COMBINE AND THRESHING DEVICE MOUNTABLE ON THE COMBINE BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a combine and a threshing device which can be mounted on the combine.

[1] A transmission case equipped with a case input shaft through which a driving force from an engine is transmitted and a forward output shaft interlocked with the case input shaft bevel gear mechanism to transmit a driving force of the case input shaft to a steering cylinder, There is one disclosed in Patent Document 1 as a combine installed on the front side of the apparatus.

The combine disclosed in Patent Document 1 has a gear case (equivalent to a transmission case) mounted on the front surface of the threshing device. The gear case includes an input shaft projecting to the left, a gear transmission mechanism incorporated in the gear case, and a bevel gear mechanism.

The input shaft is interlocked with an engine output shaft through a belt transmission mechanism, a first output shaft of the counter case, a first counter shaft, and a belt transmission mechanism. The gear case shifts the driving force of the input shaft by the gear transmission mechanism, and changes the direction by the bevel gear mechanism and transmits it to the swing (as described in paragraphs [0021] and [ ).

Further, in the combine, there is one disclosed in Patent Document 2 which is provided with a power transmitting mechanism capable of forward driving and reverse driving of the preloading portion.

Patent Document 2 describes three types of power transmission mechanisms.

The first power transmission mechanism transmits the driving force of the output shaft of the engine to the input shaft of the counter case and transmits the driving force of the cutting output shaft of the counter case to the cutting input shaft of the preliminary part, .

The power switching mechanism includes a slide gear provided with gears and reverse rotation gears provided on a preliminary transmission shaft for transmitting the driving force of the input shaft to the cutting output shaft and slidably movable on the cutting output shaft. The power transmission mechanism transmits the power in the normal rotation direction to the cutting input shaft when the gear of the preliminary transmission shaft and the slide gear are engaged with each other. When the intermediate gear engaged with the reverse rotation gear of the preliminary transmission shaft and the slide gear are engaged , And transmits the power in the reverse rotation direction to the cutting input shaft.

The second power transmission mechanism transmits the driving force of the output shaft of the engine to the input shaft of the threshing device-side mission case through the drive shaft provided with the universal joint, and transmits the driving force of the output shaft of the threshing device-side mission case to the HST of the traveling mission case And a work output shaft protruding from the traveling mission case.

The cutting output shaft of the threshing device-side mission case transmits power to the cutting input shaft of the pre-loading portion via the one-way clutch and the cutting rotary clutch. The work output shaft of the traveling mission case transmits power to the mowing input shaft through the mowing reverse rotation clutch.

When the sheathed forward rotation clutch is operated as a link, the forward rotation power is transmitted to the cutting input shaft, and when the sheathed reverse rotation clutch is operated as an input, reverse rotation power is transmitted to the cutout input shaft.

The third power transmission mechanism transmits the driving force of the output shaft of the engine to the input shaft of the threshing device side mission case through the drive shaft provided with the universal joint, And transmits the driving force of the cutting input shaft to the cutting two axes through the power switching mechanism.

The power switching mechanism includes a bevel gear dedicated for turning and a bevel gear dedicated for reverse rotation supported rotatably on a cutting input shaft and includes a bevel gear fixed to a cutting input shaft in a state of being engaged with a bevel gear dedicated for reverse rotation, And a sliding member that is spline-fitted to the input shaft. When the sliding member is made to fit in the groove portion of the bevel gear for exclusive use of turning, the power switching mechanism transmits the forward rotation power to the bobbin shafts, and when the sliding member is inserted into the groove of the reverse bevel gear, (See paragraphs [0016] to [0023], [0028], [0029], [0033], [0035], [0036], and Figures 4 and 6 of Patent Document 2 , See Fig. 8).

[2] In addition, the combine described in Patent Document 2 includes a forward clutch that transmits a forward driving force to a preload portion, and a reverse clutch that transmits a reverse driving force to the preload portion, So that the cut portion is driven by forward rotation. Even if clogging occurs in the preliminary mounting portion, it is possible to reverse drive the cut portion by switching operation of the reverse rotation clutch to the connected state, and it is easy to solve the clogging.

The combine has a traveling mission case having an input shaft connected to the output shaft of the engine via a drive shaft and a traveling mission case having an output shaft connected to the output shaft of the threshing side mission case via an input shaft via a belt and an input shaft.

In the threshing side transmission case, a cutout output shaft is provided to protrude. This cut-off output shaft transmits power to the cutting input shaft through a one-way clutch, an output pulley, a cutaway positive rotation clutch, and a forward rotation pulley.

And a work output shaft projects from the traveling mission case. The work output shaft is mounted with the output pulley through the one-way clutch and a reverse rotation input pulley fixedly installed. The reverse rotation input pulley is connected to a reverse rotation output pulley fixed to the cutting input shaft via a belt. This belt is equipped with a reverse rotary clutch.

In the combine described in Patent Document 2, one combing clutch lever is provided. By operating the combing clutch lever, the forward rotation clutch is engaged and the forward rotation power is transmitted to the pre-loading portion, And the power of the reverse rotation is transmitted to the preload part.

That is, the cutting clutch lever is supported between the forward link dedicated link member and the reverse link exclusive link member so as to be capable of being rotated in the left-right direction and backward and forward. The cutting clutch lever is tilted from the connecting groove of the lever guide to the forward rotation side and fitted in the groove of the torque-transmitting link member, and is slid forward in the forward-dedicated groove of the lever guide. Then, the forklift dedicated link member rotates, its mounting portion moves upward, and the torque for exclusive use clutch wire connected to the mounting portion is pulled, and the torque cutting clutch is connected.

On the other hand, the cut clutch lever is deflected to the reverse rotation side in the connection groove of the lever guide to fit the groove of the reverse link exclusive link member, and is slid forward to the reverse specific groove of the lever guide. Then, the reverse link dedicated link member rotates, its mounting portion moves upward, and the clutch reverse clutch dedicated to the reverse clutch connected to the mounting portion is pulled to input the reverse reverse clutch. (As described above, (See FIGS. 6 and 7).

[3] The threshing device mounted on the combine as described above is provided with a tilting process for performing a threshing process on a cut tile supplied to the feeder by being rotationally driven by a support shaft as a fulcrum, (See, for example, Japanese Patent Application Laid-Open No. 2001-34430). The outer surface of the straight body portion formed in the shape of a spiral shape is provided with a spiral shape.

In addition, a plurality of tappets and the like bent in a V-shape are formed on the outer periphery of a swing main body formed in a cylindrical shape to constitute a swing (see, for example, Patent Document 4).

[1] Problems to be solved in the background art [1] are as follows.

In the combine, when clogging occurs in the preliminary mounting portion, clogging can be easily solved if the cut-off portion can be driven in the rotational direction opposite to the forward rotational direction driven at the time of operation.

In the case of adopting the above-described conventional technique to enable forward and reverse rotation drive of the preloading portion, the entire forward / reverse rotation switching mechanism may be installed in a transmission case or a cutting input shaft, or a reverse rotation power may be taken out from a running- And a reverse rotation transmission mechanism for transmitting the rotation to the input shaft. Then, the cost tends to increase due to the manufacture and equipment of the forward and reverse rotation switching mechanism and the reverse rotation transmission mechanism. Further, the overall structure of the transmission device tends to become complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a combine capable of performing forward and reverse rotation drive of an installation part inexpensively and structurally simple.

[2] Problems corresponding to the background art [2] are as follows.

When the conventional technique described above is used to enable the forward and reverse rotational drive of the preloading portion by the switching operation between the forward clutch and the reverse clutch, the state in which the clutch operating portion is engaged with the forward clutch and the state in which the reverse clutch is engaged And a link mechanism of a complicated structure is required to link the clutch operating part and the clutch.

It is an object of the present invention to provide a clutch control apparatus and a clutch control apparatus capable of performing forward and reverse rotation drive of a cutaway portion in a state in which both forward clutch and reverse clutch are prevented from being operated in a connected state, Combine.

[3] Problems to be solved in the background art [3] are as follows.

In the above-described configuration, since most of the feeder is used in the feeder arrangement space and only a narrow space remaining around the feeder is used as the process space for the threshing process, a large amount of cut- The processing space is likely to be saturated. When the saturation occurs, the throat processing product stays in the processing space, so that the throat processing product can be removed from the receiving net A problem that the oil is filtered and the load required for the threshing process is increased, and the electric system against the tilting is damaged.

It is an object of the present invention to provide a skid-steerable structure capable of sufficiently performing a threshing process on a threshing-processed product without causing an increase in the load required for the threshing process even when a large amount of threshing- And to provide a threshing apparatus having the same.

[1] Means for solving the problem [1] are as follows.

A combine having a threshing device having a tilt and an engine mounted on a traveling body, and a cutout portion provided on a front portion of the threshing device,

A transmission case having a case input shaft to which a driving force from the engine is transmitted and a front output shaft which is coupled to the case input shaft through a bevel gear mechanism so as to transmit a driving force of the case input shaft to a front- Side,

A cutout output shaft interlocked with the case input shaft through the bevel gear mechanism so as to be driven in a rotational direction opposite to the rotational direction of the case input shaft,

A forward rotation clutch for interlocking the case input shaft and one of the mowing output shafts and the mowing input shaft so as to transmit a driving force in the forward rotation direction to the mowing input shaft of the mowing section,

And a reverse rotation clutch is provided for interlocking the other of the case input shaft and the cutaway output shaft with the cutting input shaft so as to transmit a driving force in a reverse rotation direction to the cutting input shaft of the preloading portion.

According to this configuration, when the forward clutch is operated in the engaged state and the reverse clutch is operated in the released state, the drive force of the case in which the forward rotation clutch is interlocked with the case input shaft and the cutaway output shaft is transmitted to the cutting input shaft. Then, the rotation direction of the case input shaft and the rotation direction of the cutaway output shaft are opposite to each other due to the bevel gear mechanism, so that the cutting input shaft is driven forward.

On the other hand, when the forward clutch is operated to the disengaged state and the reverse clutch is operated to the engaged state, the drive force of the case input shaft and the cutoff output shaft, to which the reverse rotation clutch is interlocked, is transmitted to the cutting input shaft. Then, the rotation direction of the case input shaft and the rotation direction of the cutting output shaft are opposite to each other due to the bevel gear mechanism, so that the cutting input shaft is driven in reverse rotation.

As a result, even if clogging occurs in the preloading portion, it is easy to eliminate clogging by driving the cutoff portion reversely, and the bevel gear mechanism can be obtained inexpensively by using the rotational direction converting means, and the overall structure of the transmission device is simply completed And can be obtained as light as possible.

In a preferred embodiment, the case input shaft and the cutout output shaft are arranged in the transverse direction of the running vehicle with the tilting output shaft interposed therebetween.

According to this configuration, the case input shaft and the cutout output shaft are arranged in a straight line or in a state close to the transverse direction of the traveling gas, so that the size when viewed from the side of the traveling base of the transmission case can be minimized.

As a result, it is possible to obtain a simple state in which the transmission case is arranged compactly on the front side of the threshing device, which is easy to solve the clogging by driving the cut-off portion in the reverse direction.

In a preferred embodiment, the reverse rotation clutch is configured to be maintained in a connected state by an artificial operation.

According to this configuration, it is possible to obtain a state in which the occurrence of troubles due to the reverse rotation drive of the pre-loading portion can be avoided, which is easy to solve the clogging by driving the cut-

That is, when the cut portion is driven in reverse rotation for a long time, an unreasonable force may be applied to the apparatus of the pre-installation portion. According to the configuration of the third aspect of the present invention, it is necessary to consciously perform maintenance of the reverse rotation clutch in the connected state. This makes it easy to take care that the reverse rotation drive of the preloading portion does not become unnecessarily long, such as intermittently performing the switching operation to the connected state of the reverse rotation clutch in the reverse rotation drive of the cutaway portion.

[2] Means for solving the problem [2] are as follows.

A combine having a threshing device with a tilt and an engine mounted on a running vehicle, and a cut-off portion provided on a front portion of the threshing device,

A forward clutch operating member operable to switch the forward clutch and a reverse clutch operating member operable to switch the reverse clutch,

When the forward clutch is in the engaged state, the operating state is switched to a state in which the switching operation to the connected state of the reverse rotation clutch is inhibited, and when the forward rotating clutch is in the released state, Wherein a check mechanism is provided.

According to this configuration, even if an attempt is made to switch the reverse rotation clutch to the connection state while the forward rotation clutch is in the engaged state, the reverse rotation clutch is not switched to the connected state by the action of the check mechanism. Then, even if the forward clutch operating member for switching the forward clutch and the reverse clutch operating member for switching the reverse clutch are provided, respectively, the forward clutch is in the engaged state and the reverse clutch is in the engaged state Can not. As a result, the forward clutch and the forward clutch operating sphere serving as the operating sockets thereof can be linked at all times in a linked state, and the reverse clutch and the reverse clutch clutch sphere serving as the operating sphere thereof can be linked .

Therefore, it is possible to perform forward and reverse rotation of the cut-off portion while preventing the reverse rotation clutch from being switched to the connection state in a state where the forward rotation clutch is in the connected state. The structure in which the forward rotation clutch is also connected to the reverse rotation clutch, It is simple and can be obtained at low cost.

In a preferred embodiment, the check mechanism includes a thrust body supported in one of the forward clutch operating portion and the reverse rotating clutch operating portion so as to be capable of swinging integrally with each other, and a thrust body provided on the other side of the forward rotating clutch operating portion and the reverse rotating clutch operating portion And the reverse rotation clutch operating lever is controlled by the contact with the contact portion to switch to the connection position of the reverse rotation clutch operating member to thereby inhibit switching of the reverse rotation clutch to the connection state.

According to this configuration, the throttle body can be swingably supported in one of the forward clutch operating portion and the reverse rotating clutch operating portion, and the throttle body can be obtained with a simple structure in which only the contact portion is provided on the other side of the forward rotation clutch operating portion and the reverse rotation clutch operating portion .

Therefore, the fact that the reverse rotation clutch can be prevented from being switched to the connection state while the forward clutch is in the engaged state can be driven for forward and reverse rotation, as well as the connection between the clutch and the operating member, It is simple and can be obtained at low cost.

[3] Means for solving the problem [3] are as follows.

A threshing device mounted on a combine,

And a tilting operation for performing a tilting process on the cut tile fed to the feeder by being rotationally driven with the support shaft as a fulcrum,

A plurality of rod-shaped members arranged so as to be spaced apart from each other by a predetermined distance in the circumferential direction of the barrel in a posture along the support shaft, a support member provided on the front and rear of the support shaft so as to support the bar- , And each of the bar-shaped members is constituted by a plurality of pitches which are arranged so as to be spaced apart from each other in the front-rear direction by a predetermined distance in a posture protruding from the bar-like member toward the outside of the barrel Device.

According to the present configuration, the tilting is provided with a space communicating with the inner chamber in the inner space, allowing entry of the throat-treated object into the inner space. Therefore, during the rotation operation, the throat-treated product around the throat-treated product and the throat-treated product brought into the inner space are subjected to a threshing process by blowing or sweeping a plurality of bar-like members or tears .

In other words, even when a large amount of cut-out curved portion is supplied to the feed room as a threshing process article, since the inner space of the rough movement can be effectively used as a processing space for the threshing treatment, avoiding the stay of the threshing- can do. As a result, there arises a problem that the throat processing product is separated from the water network in a state in which sufficient threshing processing is not performed due to the stagnation of the threshing processed product and the saturation of the processing space, and the load required for the threshing process is increased, It is possible to avoid occurrence of a problem that the system is damaged or the like.

In addition, by arranging the plurality of rod-shaped members so as to be arranged at a predetermined distance in the circumferential direction of the rod-like member, it is possible to prevent the long straw from being wound around the rod-like member, Can be avoided. In addition, not only a plurality of barbs but also a plurality of bar-shaped members forming the barrel main body also function as a threshing member for performing a threshing process by blowing or skimming against the throat-treated product, The threshing performance can be improved.

In addition to the above-described structure, the provision of the partitioning member that separates the inner space from the front and rear in the above-mentioned tilting makes the following advantages even more advantageous.

According to this characteristic configuration, it is possible to prevent the flow of the granules which have been solidified by the threshing treatment on the side of the front side of the grain bundle by the partition member, the flow toward the downstream side in the threshing direction of the grain, And the free ends of the free ends of the first and second free ends of the first and second free ends of the first and second free ends of the first and second free ends of the first and second free ends of the first and second free ends of the first and second free ends, It is possible to prevent the occurrence of tertiary loss due to the discharge from the end on the downstream side of the throttling treatment direction together with the gap.

Therefore, even when the throat-treated product is supplied in a large amount, sufficient threshing treatment can be performed on the throat-treated product without causing an increase in the load required for the thrashing treatment, It is possible to improve the threshing performance and the recovery efficiency of the grains while avoiding the damage such as the ramp or the like caused by the increase of the load, and as a result, it is possible to provide a throttle structure of the threshing device which is excellent in durability and processing ability .

In addition, it is more advantageous in that it is equipped with a winnowing fan for generating a selective wind and at the same time, the selective wind from the tuyere flows toward the partition member.

According to this characteristic configuration, the throat-treated product clogged by the partition member is disturbed by the selective wind from the tuyeres to the periphery of the partition member (around the class copper alloy) and is tumbled from the periphery of the partition member So that it is possible to avoid the possibility that the throat-treated product will be deposited immediately before the partitioning member.

Therefore, it is possible to prevent the degradation of the processing ability due to the deposition of the throat-treated product.

In a preferred embodiment, the upper side of the discharge opening is covered by a ceiling plate, and the ceiling plate is provided with a plurality of dust transfer valves for guiding the cutaway grooves toward the downstream side in the threshing direction in accordance with the rotation of the feed .

According to this characteristic configuration, the cut-off cutter fed to the feeder is transported toward the upper portion of the feeder while being subjected to a lot of blows by the plurality of cutlery and a threshing effect by the cutter in accordance with the turning of the feeder, So that it is guided toward the downstream side in the threshing direction by the plurality of dust transfer valves.

That is, it is possible to carry the throat processing product toward the downstream side in the throttling process direction while providing a plurality of tare values for the tilting process so as to sufficiently obtain an appropriate thrashing action by blowing or skimming of the tilting process product.

And if each feed value is formed so that it may have a guide part etc. which guide a threshing process material toward a threshing process direction downstream side, for example according to rotation of a barrel, it will carry out conveyance of the threshing process object toward a downstream threshing process direction more favorably. When it is made possible, and formed into a shape exclusively for threshing which only strikes or skips the threshing process, it becomes possible to obtain a more suitable threshing action on the threshing process.

Therefore, by mainly carrying the transfer material to the downstream side in the throttling process direction by the dust transfer valve, it is possible to improve the thrashing performance and the recovery efficiency of the curl without deteriorating the conveying performance of the throat processed material toward the downstream side It is possible to provide a threshing structure of a full-cullet type combined combine.

If the dust transfer valve is formed to have a length extending to the left and right side edges of the ceiling plate, the length of the dust transfer valve installed in the ceiling plate can be made sufficiently long, It is possible to carry out the conveyance guidance of the throat-treated product toward the side of the conveying direction more favorably. Therefore, it is possible to improve the conveying performance of the throat processed product toward the downstream side in the throttling process direction, while improving the threshing performance by the plurality of tachometers and the improvement of the curvature recovery efficiency.

When the ceiling plate is formed such that the rotation locus drawn by the tip of the paper feed is curved substantially along the rotation of the paper feed, So that it can smoothly guide downward on the downstream side in the threshing direction. Therefore, it is possible to improve the conveying performance of the throat processed material toward the downstream side in the throttling process direction, while improving the threshing performance by the plurality of tachometers and the improvement of the curvature recovery efficiency. In addition, Damage or the like can be avoided.

In a preferred embodiment of the present invention, a spiral blade is provided at the front end of the bobbin to feed the bobbin bundle fed and conveyed toward the front end thereof toward the rear in accordance with the rotation of the bobbin, and the spiral wing is detachably attached Respectively.

According to this characteristic configuration, in the case where the spiral blade is worn remarkably by severe contact with the cut-away curved portion or the like over a long period of time, only the worn spiral blade can be replaced. As a result, the labor and cost required for replacing the spiral blades can be greatly reduced as compared with the case where the spiral blades are equipably installed at the front end of the swing arm by welding or the like. As a result, Exchange becomes easy. And the worn spiral blade is easily exchanged, the action of the spiral wing to transport the spiral wing, which is caused when abrasion of the spiral wing is left unattended, is lowered, It is possible to easily avoid such a problem that the ability is deteriorated.

Therefore, by performing a simple modification such as detachably attaching a helical blade to the front end of the barrel, appropriate treatment for abrasion of the helical blade can be carried out simply and inexpensively. As a result, wear of the helical blade It is possible to avoid deterioration of the threshing ability due to the thrust.

In addition to the above configuration, it is arranged to cover the front end of the bobbin from below so as to be located below the bobbin, thereby to take out the bobbin fed and conveyed toward the front end of the bobbin, And at least the portion of the conveyance auxiliary guide located on the downstream side in the direction of rotation of the paper feed unit is detachable so that the conveyance auxiliary guide is in a state of severe contact with the cut- It is possible to replace only the abraded conveyance assistant guide. This makes it possible to greatly reduce the labor and cost required for replacement of the abraded conveyance assistance guide, for example, as compared with the case where the conveyance assisting guide is equipped by, for example, welding or the like, , It becomes easy to replace the abraded conveyance assistance guide. Further, since the abrasion of the abraded conveyance assisting guide is facilitated, a gap formed between the helical blade and the conveyance assisting guide, which is caused when the abrasion of the conveyance assisting guide is left, It is possible to easily avoid such a problem that the spiral blade conveying action of the spiral wing with respect to the curved portion is lowered and the threshing ability is lowered in accordance with the lowering.

However, the cut grooves, etc., which are conveyed backward by the helical wing in accordance with the rotation of the feed coils, are influenced by the feed coils and are collected on the downstream side of the feed coils in the feed coils. As a result, in the conveyance assisting guide, the portion located on the downstream side in the direction of rotation of the paper feeder is in intimate contact with the cutaway grooves and the like, and wear due to the contact is likely to occur.

Therefore, in consideration of this point, if the downstream side portion of the conveying auxiliary guide in the direction of rotation of the feeding means is detachable, it is possible to prevent the conveying auxiliary guide from being moved downward If the side portion is significantly worn, only the worn portion can be replaced. This makes it possible to further reduce the cost required for the replacement as compared with the case in which the entire transportation assistance guide is exchanged.

Therefore, by performing a simple modification such that at least the portion located on the downstream side in the direction of rotation of the feeding and conveying guide is detachable, appropriate treatment for abrasion of the carrying aid guide can be performed simply and inexpensively As a result, deterioration of the threshing performance due to abrasion of the transportation assisting guide can be easily avoided.

In a preferred embodiment of the present invention, a water supply network is disposed to cover the raising from below, a ceiling plate is disposed so as to cover the raising from above, and between the water supply network and the ceiling plate is formed a guide surface And a joint member is detachably attached thereto.

According to this characteristic configuration, when the guide surface of the coupling member is significantly worn by severe contact with the cut-away groove or the like over a long period of time, only the worn joint member can be replaced. As a result, the labor and cost required for replacing the worn joint member can be significantly reduced as compared with the case where the joint member is equipped by welding or the like so as not to be detachably connected to the water channel or the ceiling board. As a result, The member can be easily exchanged. And the worn joint member can be easily exchanged, whereby the inner surface of the water tube and the inner surface of the ceiling plate, which are caused by abrasion of the joint member, can not be connected in series by the guide surfaces of the joint members, It is possible to easily avoid the problem that the threshing performance is deteriorated due to the smooth flow of the cutting blade and the like over the ceiling plate.

Therefore, by performing a simple improvement such as detachably attaching the joint member between the water pipe and the ceiling plate, it is possible to perform a proper treatment for the wear of the joint member simply and inexpensively, and as a result, It is possible to avoid deterioration of the threshing ability due to the thrust.

The forward clutch operating member 52 is moved along the guide groove 51a (see FIG. 4) of the operation panel 51 around the axis of the rotary support shaft 55 in the transverse direction of the running support shaft 55 When the clutch is swung in the forward and backward directions of the traveling gas and positioned on the front end side of the guide groove 51a, the forward clutch operating member 52 is engaged. Then, the forward clutch operating member 52 performs the upward / downward operation of the swinging arm 61 to pull up the swing link 63. Thereby, the inner cable of the operation cable 64 is tensioned to pivot the tension member 40b so as to press the tension member 40b against the transmission belt 40a. When the transmission belt 40a is in the tension state, Lt; / RTI >

8 shows the operating state of the forward clutch operating member 52 to the disengaged state. As shown in Fig. 8, when the forward clutch operating member 52 is positioned on the rear end side of the guide groove 51a, the forward clutch operating member 52 is disengaged. Then, the forward clutch operating member 52 moves the swinging arm 61 downward and swinging to move the swinging link 63 downward. Thereby, the inner cable of the operating cable 64 is loosely operated to pivot the tension member 40b so as to release the pressing of the transmission belt 40a, so that the transmission belt 40a is in the loose state and the forward clutch 40 Is released.

Then, the reverse rotation clutch operating member 41 rocks the tension member 41b toward the connection side. Thereby, the tension roller 41c tenses the transmission belt 41a, and the reverse rotation clutch 41 is engaged. At this time, the reverse clutch 41 is maintained in a connected state by being held by the articulation operation with the reverse clutch operating member 41 engaged.

7 shows an operation state of the reverse rotation clutch operating member 54 to a disengaged state. As shown in Fig. 7, when the holding operation of the reverse rotation clutch operating member 54 in the engaged position is released, the reverse rotation clutch operating member naturally descends and swings to become disengaged. Then, the reverse rotation clutch operating member 54 rocks the tension member 41b toward the dismount side. Thereby, the tension roller 41e releases the operation of tilting the transmission belt 41a, the transmission belt 41a is in a loose state, and the reverse rotation clutch 41 is in the released state.

4, the accelerator operation opening 53 is supported by a support member 58 through a support shaft 57 which penetrates the base end side of the accelerator operation opening 53, Direction around the central axis.

7 shows the operating state of the accelerator operation opening 53 at a high speed position (high). As shown in Fig. 7, the accelerator operation opening 53 is pivoted around the guide groove 51b (see Fig. 4) of the operation panel 51 around the transverse direction axial center of the running body of the supporting shaft 57 And is positioned on the rear end side of the guide groove 51b. Then, the accelerator operation opening 53 becomes the high-speed position (high), and operates the accelerator apparatus to the high-speed state. As a result, the engine 20 is in a high-speed state for work in which the engine 20 is rotated at a high rotation speed set for work.

8 shows an operation state of the accelerator operation opening 53 at a low speed position (low). As shown in Fig. 8, the accelerator operation opening 53 is positioned on the front end side of the guide groove 51b. Then, the accelerator operation opening 53 is set to the low speed position (low) to operate the accelerator apparatus to the low speed state. Thereby, the engine 20 is brought to the low-work-use low-speed state in which the engine 20 rotates at the low rotation speed set for the reverse rotation drive of the preloading section 10. [

As shown in Figs. 4, 6 and 7, the operating portion includes a holding mechanism 70 having a holding body 71 formed by a band-shaped plate member having one end side connected to the swinging arm 61, And a high-speed reverse rotation check mechanism (80) having a high-speed reverse rotation check body (81) constituted by a bending lever body connected to the ball (53).

The checking mechanism 70 includes the checking body 71 and the contact portion 73 constituted by the bending lever 72 extending from the tension member 41b toward the upper surface side of the operation panel 51, Respectively.

The claw body 71 is constituted by a band-shaped plate member connected to the swing arm 61 so that it is supported by the forward rotation clutch operation tool 52 via the swing arm 61 and the rotation support shaft 55 , And moves integrally with the forward rotation clutch operating member (52). The contact portion 73 is constituted by the bending lever 72 extending from the tension member 41b to which the reverse rotation clutch operation opening 54 is connected so that the contact portion 73 is moved in unison with the reverse rotation clutch operation opening 54 And is provided in the reverse rotation clutch operating member 54.

7 is a side view of the check mechanism 70 in an operating state. 7, when the forward rotation clutch operating member 52 is operated in the engaged position, the claw member 71 is moved in the same height as the arrangement height of the operation board 51 by the swinging arm 61 . Then, the claw body 71 becomes the acting position where the claw acted portion 71a made of the end portion of the band-shaped plate enters the movement path of the contact portion 73. [ As a result, when the counter body 71 is operated to switch the reverse rotation clutch operating member 54 from the disengaged state to the engaged position, the contact between the countercurrent operating body 71a and the contact portion 73 It is impossible to move the reverse clutch operating member 54 to the engaged position.

That is, when the forward clutch 40 is in the engaged state, the damping mechanism 70 moves the damping action portion 71a of the claw body 71 and the contact portion 73 of the reverse clutch operating member 54 The engagement of the reverse rotation clutch actuator 54 with the engaged position of the reverse rotation clutch actuator 54 is inhibited by the contact and thereby the switching operation of the reverse rotation clutch 41 to the engaged state is inhibited.

8 is a side view of the check mechanism 70 in the released state. 8, when the forward clutch operating member 52 is operated in the disengaged state, the claw member 71 is moved to a position lower than the arrangement height of the operation board 51 by the swinging arm 61 Down operation. Then, the claw body 71 becomes a releasing position retracted from the moving path of the abutting portion 73 to the outside thereof, so that the reverse clutch operating member 54 is switched from the disengaged state to the engaged position Thereby avoiding contact between the contact portion 73 and the scavenging portion 71a when operated.

That is, when the positive rotation clutch 40 is in the released state, the check mechanism 70 releases the switching check of the reverse rotation clutch operating member 54 to the engaged position, And is released to release the switching check into the connection state.

The high-speed reverse rotation check mechanism 80 includes the high-speed reverse rotation checker 81 and the contact portion 82 formed by the bending lever 72.

The contact portion 82 is constituted by the bending lever 72 extending from the tension member 41b to which the reverse rotation clutch operation opening 54 is connected so that the contact portion 82 is moved in unison with the reverse rotation clutch operation opening 54 And is provided in the reverse rotation clutch operating member 54. The high-speed reverse rotation claw 81 is provided with a claw-acting portion 83 composed of bent portions of the bending lever body constituting the high-speed claw- The high-speed reverse rotation claw 81 is attached to a holder 84 supported by the operation panel 51 at a position between a portion connected to the accelerator operation opening 53 and the cramping operation portion 83 And is kept movable. The holder 84 is supported by the operation panel 51.

7 is a side view in the operating state of the high-speed reverse rotation check mechanism 80. Fig. As shown in Fig. 7, when the accelerator operation opening 53 is operated to the high speed position (high), the high-speed reverse rotation check body 81 is moved to the rear side of the traveling gas by the accelerator operating opening 53. [ Then, when the high-speed reverse rotation claw 81 is in the operative position and the reverse rotation clutch operating member 54 is to be switched from the disengaged state to the engaged state, Thereby imparting resistance to the movement of the reverse rotation clutch operating member 54 to the engaged position by the contact with the contact portion 82. [

That is, when the engine 20 is in the high-speed operation state, the high-speed reverse rotation check mechanism 80 controls the operation of the high-speed reverse rotation claw 81 and the reverse rotation clutch operator 54 The contact with the contact portion 82 makes it difficult for the reverse-rotation clutch operating member 54 to move to the engaged position, thereby making the reverse rotation clutch 41 operative to check the switching to the connected state.

8 is a side view of the high-speed reverse rotation check mechanism 80 in the released state. As shown in Fig. 8, when the accelerator operation opening 53 is operated to the low speed position low, the high-speed reverse rotation check body 81 is moved to the forward direction of the traveling gas by the accelerator operating opening 53. [ Then, the high-speed reverse rotation check body 81 becomes the release position, and the high-speed reverse rotation check body 81 when the reverse rotation clutch operation opening 54 is switched from the disengaged state to the engaged position, And the contact portion 82 of the counterrotating clutch operating member 54. [0064] As shown in Fig.

That is, when the engine 20 is in the low-speed operation state, the high-speed reverse rotation check mechanism 80 cancels the switching check of the reverse rotation clutch operating member 54 to the engaged position, 41 to the connected state.

That is, when the work is performed, the accelerator operation opening 53 is operated at the high speed position, the reverse rotation clutch operating opening 54 is operated to the disengaged position, and the forward rotation clutch operating opening 52 is closed Operate in engaged position. Then, the engine 20 rotates in a high-speed work state and the driving force from the output shaft 20a of the engine 20 is transmitted through the belt transmission mechanism 25, the tie driving shaft 26 and the belt transmission mechanism 35, Is transmitted to the case input shaft 37 of the case 36 and the case input shaft 37 is driven and the driving force of the case input shaft 37 is transmitted to the cutout output shaft 39 through the bevel gear mechanism 43, (39) is driven in a rotational direction opposite to the rotational direction of the case input shaft (37). The forward clutch 40 is engaged and the driving force of the case input shaft 37 is transmitted to the cutting input shaft 42 by the forward clutch 40 and the reverse clutch 41 is released, 39 is not transmitted to the cutting input shaft 42, so that the cutting input shaft 42 is driven at the working rotation speed in the normal rotation direction. The driving force of the cutting input shaft 42 is transmitted to the drive shaft 45 of the cutting device 16 through the electric chain 44 directly to the conveying end side of the feeder conveyor 11 by the electric chain 44 and the electric chain 47 to the drive shaft 46 of the auger 18 via the transmission chain 44 and the transmission chain 47 and the transmission belt 50 to the drive shaft 48 of the rotary reel 17, The conveyor 11a, the auger 18, the cutting device 16, and the rotary reel 17 are driven in the normal rotation direction at a rotational speed suitable for the operation.

When clogging occurs in the preloading section 10, the accelerator operation opening 53 is switched to the low speed position, the forward rotation clutch operating member 52 is switched to the disengaged state, The clutch operating member 54 is switched to the engaged position. At this time, the switching operation to the low speed position (low) of the accelerator operating opening 53 is performed to release the switching check of the reverse rotation clutch 41 by the high speed reverse rotation check mechanism 80, To the disengaged position and disengages the reverse rotation clutch 41 by the check mechanism 70 to switch the reverse rotation clutch operating member 54 to the engaged position .

The engine 20 then rotates to the low-speed state for the non-work and the driving force from the output shaft 20a of the engine 20 is transmitted to the belt 20 via the belt transmission mechanism 25, the tie driving shaft 26 and the belt transmission mechanism 35 Is transmitted to the case input shaft 37 of the case 36 and the driving force of the case input shaft 37 is transmitted to the cutout output shaft 39 via the bevel gear mechanism 43 so that the cutout output shaft 39 is connected to the case input shaft 37 in the rotational direction opposite to the rotational direction of the drive shaft. The forward clutch 40 is released and the drive force of the case input shaft 37 is not transmitted to the cutoff input shaft 42 and the reverse rotation clutch 41 is engaged and the drive force of the cutaway output shaft 39 is reversed Is transmitted to the cutting input shaft (42) by the clutch (41), and the cutting input shaft (42) is driven at the non-work rotational speed in the reverse rotational direction. The driving force of the cutting input shaft 42 is transmitted to the drive shaft 45 of the cutting device 16 through the electric chain 44 directly to the conveying end side of the feeder conveyor 11 by the electric chain 44 and the electric chain 47 to the drive shaft 46 of the auger 18 via the transmission chain 44 and the transmission chain 47 and the transmission belt 50 to the drive shaft 48 of the rotary reel 17, The conveyor 11a, the auger 18, the cutting device 16, and the rotary reel 17 are driven at a rotational speed suitable for eliminating clogging in the reverse rotation direction, thereby facilitating elimination of clogging. At this time, the reverse clutch 41 is connected as long as the reverse clutch clutch pedal 54 is artificially maintained in the engaged position, so that the preload 10 is reversely driven, When the retaining operation of the operating member 54 in the engaged position is canceled, the reverse clutch operating member 54 is naturally switched to the disengaged state so that the reverse rotating clutch 41 is released, The reverse rotation of the motor 10 is stopped.

Fig. 5 is a side view of the chain transmission mechanism having the electric chain 44. Fig. 5, the chain transmission mechanism includes a guide rail 89 wound around the electric chain 44 so as to be guided, and a tension arm 89 supported by the transverse side wall portion 11b of the feeder 11, And a chain tensioning mechanism (90) having a chain tensioning mechanism (91).

5 and 10, the chain tension mechanism 90 includes the tension arm 91 as well as a spring 92 connected to the tension arm 91, The tension arm 91 is pivotally moved around the support shaft 93 by the spring 92 so that the loosely rotatable tension member 94 of the tension arm 91 is engaged with the transmission chain 44 So that the electric chain 44 is given a tensile force.

The side of the spring 92 opposite to the side connected to the tension arm 91 is connected to the spring support lever 96 supported by the bracket 95 to the side wall portion 11b of the feeder 11 . The tension chain member 94 acts on a portion 44a of the transmission chain 44 that becomes a relaxed side at the time of the forward rotation of the preload portion 10. [ The tension arm 91 includes a tension limiting member 97 mounted on the tension arm 91 and the spring support lever 96.

9 and 10, the tension limiting member 97 and the spring support lever 96 are connected to each other via a connecting pin 98 so as to be relatively rotatable. The tension limiting member 97 and the tension arm 91 are connected to each other by a support shaft 99 that supports the tension member 94 in a loosely rotatable manner. The support shaft 99 is inserted through the restriction hole 100 provided in the restriction member 97 so as to be slidable.

9 (a) shows the chain tension operating state of the tension member 94 in the case where the preload 10 is driven forward. As shown in Fig. 9A, when the preload 10 is driven forward, the portion 44a where the tension chain body 94 of the electric chain 44 acts acts as a relaxed side. Then, the tension member 94 tenses the chain portion 44a by a tensioning operation by the spring 92. [

Fig. 9 (b) shows the operational state of the tension limiting member 97 when the preload 10 is driven in the reverse direction. 9 (b), when the preload portion 10 is driven in the reverse direction, the straining regulator 97 regulates the movement against the spring 92 of the tension rail 94. As shown in Fig. As a result, the portion 44b of the transmission chain 44, which is to be the relaxed side, is less likely to come off the guide limb 9 due to the reverse rotation of the preload portion 10.

That is, when the portion 44a of the transmission chain 44 on which the tension ring gear 94 is applied becomes the tension side, the tension ring gear 94 is moved against the spring 92 due to this tension. The tension limiting member 97 then supports the tension member 94 via the support shaft 99 so as to restrict the movement against the spring 92 of the tension member 94. [ As a result, in the tension limiting member 97, the portion 44b to be the relaxed side of the transmission chain 44 due to the reverse rotation driving of the preloading portion 10 is prevented from being significantly loosened from the guide shaft 89 Thereby suppressing the relaxation margin of the portion 44b.

In the threshing device 5, a straw discharge port 118 is formed in the rear of the water pipe 117, which is a downstream side end in the threshing direction, for discharging the curved path to the outside of the apparatus. Below the water column 117, a rocking and sorting mechanism 119 for performing a sieving process on the processed material squeezed from the water column 117 is disposed. A winnowing fan is provided in the lower front of the shaking motion separating mechanism 119 for supplying a selective air to the treated water which is filtered from the water pipe 117 and the treated water to be sieved, (Not shown).

A grain fan 133 and a grain sheave 134 for precise sorting are disposed in the lower portion of the sheave case 129 from the front side of the sheave case 129 in that order. At the upper part of the shaking motion separating mechanism 119, the sorting processing products which are filtered from the water pipe 117 in the state where the monolithic curled pieces or the straw debris and the like are mixed are fed to the upper grain pan 130, the chaff sheave 131, Is picked up by the rack 132, and subjected to rough selection processing by screening. In the lower part of the shaking motion separating mechanism 119, a sorting process product which is filtered from the chief sheave 131 in a state in which the monolithic curved grains and the streaked curved grains are mixed is used as the lower grain pan 133 or the grain sheave 134 ), And performs precise sorting processing by sieving. As a result, it was found that the sorted material was a mixture of monolithic grains as first material (first material), grains as a second material (second material), straws and the like, and straw as a third material It is selected by dust like crumbs.

The tuyere 120 is rotationally driven with the tuyere drive shaft 26 as a fulcrum by the power from the engine 20 transmitted through the belt transmission mechanism 25, thereby generating a selective air. The selective wind is supplied through the three air paths (R1 to R3) toward the sorting processing products filtered from the water channel 117 and the sorting processing products selected by the rocking screening mechanism 119 and the like, Small straw crumbs and the like are transported toward the discharge port 123 on the downstream side in the threshing direction. The No. 1 collecting unit 121 collects the solidified grains drained from the grain sheave 134 of the shaking motion separating mechanism 119 in a state in which dust such as straw is removed by the sorting wind from the tuyeres 120, . A No. 1 screw conveyor 28 driven by a power from an engine 20 which is transmitted through a tuyere 120 or the like is arranged in the left and right direction at the bottom of the No. 1 collecting unit 121. The No. 1 screw conveyor 28 transports the No. 1 item recovered from the No. 1 recovery unit 121 toward the lifting screw 137 (see FIG. 2) provided continuously at the right end thereof.

The No. 2 recovery unit 122 is a filter unit that does not separate from the grain sheave 134 of the shaking motion separating mechanism 119 and is made of a mixed material such as curled grains or straw crumbs stuck to the rear end of the grain sheave 134, And collects a mixed material such as curled grains or straw crumbs stuck to the stove rack 132 of the mechanism 119 as stones.

11 to 17, the sweep 5a includes a truncated conical portion 141 forming a front end portion thereof and a glazing processing portion 142 connected to the rear end portion of the vowel portion 141, Respectively. The outer circumferential surface of the vowel portion 141 is guided along the rotation of the sweep 5a toward the rear sweeping processing portion 142 so as to feed the cut sweeps fed and conveyed to the feed port 125 by the feeder 11 Two helical wings (an example of a helical tooth portion) 143 are provided.

The squeegee processing unit 142 includes a first plate 144 (an example of a support member) integrally provided at a front portion of the threshing output shaft 38, a second plate integrally provided at front and rear intermediate portions of the threshing output shaft 38, A third plate 146 (an example of a support member) integrally provided at the rear end of the threshing output shaft 38, and a plate 146 (An example of rod-shaped members) 147 and each of the rake frames 147, each of which is composed of a round pipe steel material supported in such a manner as to be arranged so as to be spaced apart at a predetermined distance in the peripheral direction of the ramp 5a, And a plurality of tachometers 148 arranged so as to be spaced apart from each other by a predetermined distance in the forward and backward directions in a posture projecting from the swing frame 147 toward the outside of the swash plate 5a.

That is, in the sweep 5a, a plurality of spikes 148 protruding toward the outside are arranged and arranged so as to be spaced apart from each other by a predetermined distance in the circumferential direction of the glaze processing unit 142 and in the front-rear direction. The swash plate 5a is formed so that the inner space S of the sweep processing unit 142 communicates with the supply chamber 114 to allow the supply of the processed material to the inner space S. [ As a result, during the rotation operation of the sweep 5a, the swirling motion of the swirling frame 147 or the sweeping trail 148 or the swinging movement of the swirling frame 147 or And carries out a threshing process by sweeping.

In addition, even when a large amount of cut-out curved portion is supplied to the supply chamber 114 as a processed product, the inner space S of the glaze processing unit 142 communicates with the supply chamber 114, Can be effectively used as a processing space for the threshing process. Thereby, it is possible to avoid the retention of the processed material in the processing space and saturation of the processing space. As a result, in the state where the sufficient threshing process is not performed due to the retention of the treated product and saturation of the process space, the treated product is filtered from the water tube 117, or the load required for the threshing process is increased, It is possible to avoid the occurrence of problems such as breakage of the electric system for the vehicle.

In addition, not only a plurality of the traces 148 but also the six raising frames 147 forming the sweep processing unit 142 of the sweep 5a can be used as a sweeping member So that the threshing performance and the threshing efficiency can be improved.

In the front and rear intermediate portions of the sweep 5a in which the amount of the processed product is reduced as a result of a large number of grains becoming single-ended by the threshing process on the front side of the sweep 5a and being filtered from the water thread 117, The second plate 145 which is spaced forward and backward from the space S prevents the flow of the processed material in the inner space S in the throttling process direction in the inner space S of the ram 5a, The water is guided to the periphery of the sweep 5a to accelerate the sweeping of the treated water by the sweeping of the sweeping teeth 148 or the like or the sweeping of the sweeping water and the filtering off of the monolithic sweeping grains from the water pipe 117. This makes it possible for the straw discharge port 118 formed at the downstream side end portion in the throttling process direction together with the detaching gap to pass through the inner space S of the raking 5a, It is possible to prevent the occurrence of the third loss.

In addition, at the time of the rotation operation of the sweep 5a, the outside air sucked from the supply port 125 in accordance with the rotation of the spiral wing 143, along with the cutaway gaps conveyed by the action of the vowel portion 141, Smoothly flows into the periphery of the sweep 5a or the internal space S of the sweep processing unit 142. [ As a result, it is possible to prevent the outflow of straw debris generated by the threshing process from the supply port 125 to the feeder 11, and at the same time, it is possible to carry the treated material to the downstream side in the threshing direction more quickly.

In addition, the outside air sucked from the supply port 125 passes through the inside of the feeder 11 connected to the supply port 125, and the feeder 11 is connected to the cutter 16, the auger 18 (Not shown) for withdrawing the curved portion formed in the cut-off collecting portion of the cut-off conveyor 4 equipped with the cutting blade 5 and the supply port 125. Therefore, during the rotation operation of the pulley 5a, The dust and the like generated by the cutting and collecting process in the cut-off collecting section due to the suction of the feeder 143 due to the rotation of the feeder 143 can be transmitted to the inner space of the feeder 11 from the take-out port of the cut- And flows into the inner space S of the sweeping processing unit 142 through the swash plate 125. As a result, it is possible to suppress the deposition and flapping of straw crumbs and the like in the waste collecting and collecting section, and it is possible to prevent the conveyance failure of the cut grooves caused by the accumulation and deposition of the straw, .

Each of the plates 144 to 146 is circular around the threshing output shaft 38 and the elevating frame 147 is bolted to an equidistance position from the threshing output shaft 38 on the outer circumferential side thereof. That is, six raising frames 147 are arranged on the outer circumferential side of each of the plates 144 to 146 so as to be spaced apart from each other by a predetermined distance in the circumferential direction thereof, so that the diameter of the body of the rake 5a is increased . Thereby, it is possible to prevent winding of the cut-away curved portion relative to the swing 5a.

Each of the raising frames 147 has a normal posture in which the forward and backward directions thereof coincide with the forward and backward directions of the swash plate 5a and a reversing posture in which the forward and backward directions thereof are reversed from the forward and backward directions of the swash plate 5a, And are bolted to the respective plates 144 to 146 so that the front and rear directions of the swing frame 147 and the swing frame 147 are opposite to each other.

A plurality of mounting holes 147A and 147B for mounting the trailing edge 148 are arranged in the respective swing frames 147 in a state in which they are arranged at a predetermined pitch P in the forward and backward directions, The distance L1 from the front end portion to the center of the foremost mounting hole 147A and the distance L2 from the rear end portion of the raising frame 147 to the center of the rearmost mounting hole 147A are set to half the pitch ) In the same direction.

Each of the raising frames 147 is connected to and supported by the plates 144 to 146 in a state in which the front and rear directions thereof are opposite to that of the adjacent raising frames 147. Thereby, while using the same structure as the six raising frames 147, the trailing edge 148 equipped in the respective rake frame 147 is moved in the forward and backward directions with the trailing edge 148 of the adjacent rake frame 147 It can be positioned in a position shifted by half the pitch. As a result, it is possible to reduce the stroke interval of the tactile value 148 with respect to the object to be processed, without reducing the interval between the adjacent tactics 148.

In other words, it is possible to reduce the cost by making each of the raising frames 147 have the same configuration, and also to reduce the distance between adjacent tributaries 148, It is possible to effectively improve the threshing performance by increasing the number of strikes of the trailing edge 148 with respect to the processed product while effectively preventing clogging of the processed product caused by winding.

In addition, since each of the swing frames 147 is provided so as to be changeable in a normal posture and a reversed posture, the abrasion of the swinging teeth 148 located on the upstream side of the swinging processing direction, which is relatively easy to be worn out, The plurality of tactile values 148 provided in each of the elevating frames 147 are shifted from the tactile values 148 on the upstream side in the treading direction which tend to be relatively easily worn out by changing the direction of each of the tilting frames 147, And the swash plate 148 on the downstream side in the throttling process direction, which is difficult to be abraded, are exchanged. This makes it possible to effectively utilize the trailing edge 148 on the downstream side in the threshing direction in which the abrasion is small, as the trailing edge 148 on the upstream side in the threshing direction with a large amount of the treated amount.

The four mounting holes 147A located at the front and rear opposite ends of each of the raising frames 147 out of the plurality of mounting holes 147A and 147B are smaller in diameter than the mounting holes 147B located in the middle portion, Respectively.

The tactile value 148A to be mounted using the small diameter mounting hole 147A of each of the tactical values 148 is a stepped round bar steel material having a small diameter portion 148a which is inserted into the mounting hole 147A And a nut is detachably fixed to the flywheel frame 147 so that its center lies on a line passing through the center of the threshout output shaft 38 and the center of the flywheel frame 147.

The center of gravity 148B is located on the line passing through the center of the threshing output shaft 38 and the center of the raising frame 147 So that it is not detachably welded to the swing frame 147.

In other words, since each of the treads 148A located at both ends of the front and rear of the glaze processing unit 142 can be attached and detached, if the tare 148A is significantly worn by long-term use including the change of direction of the grate frame 147 , And can easily be exchanged with the new tank 148A.

As shown in Fig. 18, on the downstream side of the throttling process direction in which the amount of overhanging curvature increases, when the trailing edge 148A located at the rear end of the sweep 5a is disposed in a state of being pulled out, The spacing of the trailing edge 148A is increased, and the stagnation of the trailing edge due to the catching of the trailing edge 148A at the trailing edge after the traction can be effectively suppressed. As a result, it is possible to promote the release of the gap between the straw discharge ports 118.

As shown in Figs. 11 to 13, 19A, 19B and 20, the ceiling plate 124 is provided with a curved portion 124A which substantially curves a trajectory K of the trailing edge, A semicircular vertical wall portion 124B located at the front and rear ends of the curved portion 124A and a straight side edge portion 124C located at the right and left of the curved portion 124A. The ceiling plate 124 has a closing position for covering the upper side of the sweep 5a from above and a closing position for covering the upper side of the sweep 5a from the upper side of the sweep 5a by using a plurality of hinges 124D provided on the left side corner portion 124C as a fulcrum So that the opening / closing pivoting operation can be performed over the open position. The right side edge portion 124C is provided with a plurality of bolts 124E for fixing the ceiling plate 124 in a closed state.

The curved portion 124A is curved so as to smoothly guide the workpiece conveyed toward the upper portion of the ramp 5a in accordance with the rotation operation of the ram 5a toward the lower waterdrop 117 by the inner surface thereof. A plurality of dust transfer valves 149 for guiding the processed material conveyed to the upper portion of the supply chamber 114 toward the downstream side in the threshing direction are provided on the inner surface of the curved portion 124A in the forward and rearward directions In a state in which they are arranged at a predetermined distance apart from each other. The most forward dust transfer valve 149A among the plurality of dust transfer valves 149 is formed in an arc shape extending from the front vertical wall portion 124B to the left side edge portion 124C and the other dust transfer valve 149B are formed in an arc shape extending over the right and left side edge portions 124C.

That is, the ceiling plate 124 is provided with the curved portion 124A. By the rotation of the tilting 5a, the processed material that has been conveyed to the upper portion of the feeding chamber 114 by the plurality of trains 148, 124A and the dust conveyance valve 149, it is possible to guide smoothly toward the water channel 117 downstream in the threshing direction. Each of the dust transfer valves 149 is formed into a long circular arc shape extending to the left side edge portion 124C or the left and right side edge portions 124C. Therefore, guiding action of each dust transfer valve 149A on the processed material conveyed to the upper portion of the supply chamber 114 can be effectively improved. As a result, each of the treads 148 is formed not only in a shape having a transporting action with respect to the object to be treated, but also in a shape for exclusive use in threshing which can appropriately perform blowing or skimming with respect to the object, And as a result, the threshing performance and the transport performance of the processed product can be improved.

A joint member 150 made of a steel plate bent so as to have a guide surface 150a connecting the inner surface of the curved portion 124A and the inner surface of the water tube 117 in series is detachably connected to the right and left side edge portions 124C have. Since the joint member 150 which is located at the joint between the water channel 117 and the ceiling plate 124 and is in contact with the processed product is detachably attached to the joint member 150 as described above, Only the joint member 150 can be easily replaced. That is to say, as in the case where the joint member 150 is not detachably welded to the ceiling plate 124, for example, it is possible to replace the worn joint member 150 with the entirety of the ceiling plate 124, The treatment for abrasion of the joint member 150 can be appropriately performed without causing any disadvantage.

In addition, a small clearance is set between the tip of each of the cutoffs 148 and the lower edge of each dust transfer valve 149 in order to guide the processed product by the dust transfer valve 149. Between the tip of each tachy 148 and the inner surface of the water tube 117 is provided between the tip of each tachy 148 and the inner surface of the water tube 117 in order to facilitate the squeezing out of the water- A clearance larger than the gap set between the lower edges of the lower plate 149 is set.

As shown in Figs. 11, 12, 14 to 16 and 18, two support plates 141A are welded to the outer circumferential surface of the vortex portion 141 in the spiral 5a in the form of a spiral have. Corresponding spiral wings 143 are detachably and bolt-connected to the back surface of each of the support plates 141A in a state in which the outer edge of the corresponding spiral wings 143 protrudes outward beyond the outer periphery of the corresponding support plate 141A.

That is, in this swiveling 5a, the uncut portion fed and conveyed to the supply port 125 by the feeder 11 is conveyed backward by the feeder 11 in accordance with the rotation so as to vigorously contact with the cut- Two spiral blades 143 that are susceptible to abrasion due to abrasion are installed to be detachably attached to the vortex portion 141 of the ram 5a so that each spiral blade 143 Is worn out considerably, only the spiral blade 143 can be replaced easily. As a result, it is possible to reduce the time required to replace the worn-out wing 143 with the worn-out wing 143, for example, when the wing blade 143 is welded to the vowel 141 in a non-removable manner It is possible to appropriately perform the treatment against the abrasion of the spiral wing 143 without causing any economic disadvantage.

Further, each of the support plates 141A is reinforced by a plurality of reinforcing ribs 141B welded to the front surface thereof and the outer peripheral surface of the vowels 141, respectively.

The feeder 11 is provided between the front wall 126 and the water channel 117 in the threshing device 5 as shown in Figs. 11, 12, 14, 21, A conveying auxiliary guide 151 for taking in a cutaway curved portion supplied to and conveyed to the sphere 125 and assisting conveyance of the squeaky curled portion by the two spiral wings 143 is disposed. The transportation assistance guide 151 is constituted by a pair of left and right guide members 151A and 151B which are bolted to each other in a substantially U shape when viewed from the front which covers the lower side of the collection part 141 from below. The left and right guide members 151A and 151B are detachably connected to a pair of left and right support frames 152 arranged in the front and rear direction on the front wall 126 of the threshing apparatus 5 and the threshing apparatus 5, And a second plate 151b made of stainless steel for forming a guide surface extending from the front wall 126 of the threshing device 5 to the water tube 117 is welded to the first plate 151a made of stainless steel .

That is to say, in this threshing device 5, since the two bundle spiral vanes 143 assisting in conveying the bundle of bundles of the cut pieces, they are in contact with each other very much, and abrasion due to the abutment tends to occur A guide member 151A on the left side located on the upstream side in the rotation direction of the rotation 5a and a guide member 151B on the right side located on the downstream side in the rotation direction of the rotation 5a, When the whole of the conveyance assistance guide 151 is worn out by the use of the organs, only the conveyance assistance guide 151 is simply Exchangeable. When either one of the guide members 151A and 151B on the right and left sides of the transportation assistance guide 151 is significantly worn by use of organs, only the guide members 151A and 151B, which are remarkably worn, . As a result, as in the case where, for example, the transportation assistance guide 151 is welded to the water channel 117, the left and right support frames 152 and the like in a detachable manner, the water channel 117, Even when either one of the right and left sides of the conveyance assistance guide 151 is significantly worn as in the case where the support frame 152 is replaced or the conveyance assisting guide 151 is configured not to be divisible, It is possible to appropriately perform the treatment for abrasion of the conveyance assisting guide 151 without causing the same troublesome or economical disadvantages as exchanging the entirety.

In addition, since the carrying aid guide 151 is made of stainless steel which is strong against corrosion and has high strength, the frequency of replacement due to abrasion can be reduced.

As shown in Figs. 11, 13, 14 and 23, the water channel 117 is constituted by four water channel members 153 formed in the same shape, and is detachably attached to the right and left support frames 152, It is connected. Each of the water element members 153 is provided with a base frame 153A woven in a rectangular shape. In the frame of the base frame 153A, a plurality of vertical rails 153B made of a strip-shaped steel plate are arranged in the front-rear direction in a state of being spaced apart from each other by a predetermined distance in the peripheral direction of the rake 5a. A plurality of first horizontal rails 153C made of a strip-shaped steel plate curved in an arc shape are aligned and arranged in a left-right direction in a state of being spaced apart from each other by a predetermined distance in the front-rear direction of the support shaft direction of the rake 5a . Further, a plurality of second horizontal rails 153D made of piano wire curved and formed in an arc shape are arranged in the left-right direction in a state of being spaced apart from each other by a predetermined distance in the front-rear direction between adjacent first horizontal rails 153C Respectively. The mesh formed in the frame of the base frame 153A is formed so that the length of the mesh in the direction along the circumferential direction of the sweep 5a is longer than the length in the direction along the forward and backward directions, ) Is set.

That is, in the threshing process in which the sweep 5a is rotationally driven, considering the fact that the monolithic grooves or the like obtained by the threshing process with respect to the sweeping grooves flow in the rotating direction along the rotation of the sweep 5a, , And the mesh is formed into a long rectangular shape long in the rotation direction of the sweep 5a. As a result, compared with the case where the water tube 117 is configured so that the mesh has a longitudinally elongated rectangular shape elongated in the threshing direction (forward and backward direction) of the sweep 5a, It becomes easy to be filtered from the front side. As a result, it is possible to effectively prevent the generation of the peeling lips due to suppression of the filtering of the monolithic grains from the front side of the water tube (117). In addition, productivity and assembly adhesion of the water channel 117 can be improved by forming the water channel members 153 in the same shape.

As shown in Figs. 11 and 24, the chrysieve 131 for primary selection is provided with a single sorting plate 154 (see Fig. 11) connected to the sheave case 129 by bolts in a rearwardly inclined posture located above the downstream side in the sorting direction ).

A plurality of filtering down holes 154A formed in the shape of a rectangle when viewed from the plane are formed in the front side of the screen 154 (about one third of the front side of the screen 154) And are arranged in a staggered shape in which the rearwardly arranged filtering hole 154A is located between the filtering holes 154A. A plurality of squeezing members 154a and 154b formed in a rectangular shape when viewed in a plane having the sorting pieces 154a and 154b are provided in the rear side of the sorting plate 154 (about 2/3 of the rear side of the sorting plate 154 as a whole) The lowering holes 154B and 154C are arranged in a zigzag shape in which the lower row of lowering holes 154B and 154C are located between the lower row of the lower row of the lower row of the lower row.

Among the respective selection pieces 154a and 154b, the selection pieces 154a located at the left and right center sides of the selection plate 154 are formed in a scaly shape located upward in the narrower direction toward the downstream in the sorting direction. The selection pieces 154b located at the left and right ends of the discrimination plate 154 are formed in a rectangular shape shorter than the left and right center selection pieces 154a and are formed so as to be positioned upward as they are downstream in the sorting direction have.

That is, since the chrysene 131 for rough selection is constituted by a single sorting plate 154, for example, the chrysene 131 may be formed by arranging a plurality of chafers made of strip- The configuration can be simplified and the cost can be reduced.

And a squeezing hole 154A that does not include the selection pieces 154a and 154b is formed on the front side of the picksheet 131 to which the sorting processed product having a high content of the monolithic curled papers is supplied. The number of the free cutting grains that are filtered down to the grain fan 133 and the grain sheave 134 downward from the front side is increased. As a result, it is possible to increase the recovery rate of the monolithic grain bins in the No. 1 recovery section 121 located below the grain pan 133 or the grain sheave 134. [

By arranging the filtering holes 154B and 154C provided with the discriminating pieces 154a and 154b in the zigzag shape in the front, rear, left, and right positions on the rear side of the browse sheave 131, So that the sorting object on the discharge surface 131 is uniformly distributed in the left-right direction without being shifted. As a result, it is possible to facilitate the squeezing of the single-ply curled-puddle from the respective falling-down holes 154B and 154C.

In addition, by equipping the chief sheave 131 in a rearwardly inclined posture, compared to the case where the chief sheave 131 is provided in a horizontal posture, the chief sheave 131 is subjected to the screening process The force of pushing upward in the upstream side in the sorting process direction becomes large. As a result, during the sifting process, the conveyance of the sorting target to the downstream side in the sorting direction is suppressed, and the up-and-down movement of the sorting processed product becomes severe, so that the separation of the specific gravity of the sorting processed product is more effectively performed. It is possible to effectively suppress the occurrence of the third loss in which the unhardened curled papers are discharged from the discharge port 123 to the outside of the machine, and as a result, the improvement of the curled recovery efficiency .

The selection pieces 154b at the left and right ends of the chiefseve 131 are formed so as to be narrower than the selection pieces 154a at the right and left central sides, It is possible to facilitate the squeezing of the curling or the like from the squeeze-down holes 154C at the both left and right ends. As a result, it is possible to avoid a reduction in the sorting efficiency due to the accumulation of the sorting material at the left and right ends of the chrysene 131.

The ratio of the squeeze-down holes 154A which are not provided with the selection pieces 154a and 154b formed in the browse sieve 131 and the squeeze-down holes 154B and 154C provided with the selection pieces 154a and 154b Can be variously changed depending on the kind of the curved grain to be selected.

A plurality of squeeze-down holes 154C formed in a rectangular shape as viewed in a plane so as to have the rectangle-shaped selection pieces 154b on the front side of the discriminating plate 154 are provided in the front- And the rear-row narrowing-down holes 154C may be arranged in a zigzag shape.

11, the selective air passing through the upper-stage air passage R1 of the sorting air from the tuyeres 120 passes through the air passage R4 formed in the sheave case 129, And is configured to flow toward the second plate 145. As a result, the second plate 145 prevents the flow of the processing material toward the downstream side in the threshing direction, and winds the processed material toward the periphery of the swash plate 5a. As a result, it is possible to avoid the possibility that the processed material is deposited on the area immediately before the second plate 145, thereby causing trouble in the threshing process.

As shown in Figs. 11 and 14, the swash plate 5a is arranged so that the swash plate 148A located at the rear end of the swash plate 5a is located behind the rear end of the water tube 117 and faces the straw discharge port 118 . That is, at the rear end of the swing 5a, a relatively large space is formed around the periphery thereof due to the absence of the water channel 117. Thus, even if the diagonal gap is wrapped around the diaphragm 148A at the trailing edge of the swash plate, the diagonal gap between the diagonal grooves escapes from the tip of the diagonal 148A by the centrifugal force resulting from the rotation of the swash plate 5a. As a result, it is possible to effectively suppress the stagnation of the deflection groove due to the engagement with the trailing edge 148A at the rear end of the sweep 5a, thereby facilitating the discharge of the deflection groove from the straw discharge port 118.

As described above, according to the present invention, there is provided a threshing device (hereinafter referred to as a threshing device) (hereinafter referred to as a threshing device 5), the rod-shaped members (the raising frame 147) having a plurality of circular cross sections arranged so as to be arranged so as to be spaced apart from each other by a predetermined distance in the peripheral direction of the tilting 5a in the attitude along the support shaft, (The first plate 144 and the third plate 146) provided on the front and rear of the support shaft so as to support the rod-like members and the cantilevers And is configured to be arranged at a predetermined interval in the forward and backward directions in a posture of projecting in the shape of a circle.

According to this constitution, the sweep 5a has a space communicating with the supply chamber 114 therein, allowing entry of the throat-treated product into the inner space. Thus, during the rotation operation, a plurality of rod-like members (the raising frame 147) and the treads 148 are provided to the throat-treated product while stirring the throat-treated product around the throat-treated product and the throat- And performs a threshing process by blowing or skimming.

That is, even when a large amount of cut-away curved portion is supplied to the supply chamber 114 as a throat processing product, the inner space of the turntable 5a can be effectively used as a processing space for the threshing process, Saturation of the processing space can be avoided. As a result, there is a problem in that the throat processing product is filtered from the water network in a state in which sufficient threshing processing is not performed due to the stagnation of the threshing processed product and saturation of the processing space, and the load required for the threshing process is increased, It is possible to avoid the occurrence of a problem that the electric motor system is damaged.

In addition, by arranging the plurality of rod-shaped members (the raising frame 147) so as to be arranged with a predetermined distance apart in the peripheral direction of the sweep 5a, it is possible to prevent the long straw from being wound around the rod- It is possible to avoid the stay of the throat-treated product due to the winding. In addition, not only a plurality of tactile springs 148 but also a plurality of rod-shaped members forming the body of the sweep 5a are subjected to a thrashing process by blowing or skimming to the threshing process product during the rotation operation of the tilting 5a So that the threshing performance can be improved.

Since the rod-like member (the raising frame 147) and the spike 148 are formed in a circular section, the rodlike member and the spike 148 have fewer portions such as sharp corners, It is less likely that the throat processing article is damaged due to the impact of the blower 148.

Further, the trailing edge 148 protrudes in a cantilevered manner from the rod-like member (the raising frame 147) toward the outside, and the leading end of the trailing edge 148 is opened (in a state not connected to any member) Therefore, the throat-treated product wound around the tier 148 can easily move outward along the tier 148 due to the centrifugal force generated by the rotation of the tier 5a, and is in a state of being easily separated from the tip of the tier 148 , And a state in which the throat processing product is not wrapped around the tread 148 is reduced.

Further, it is advantageous in the following respects that the rod-like member (the raising frame 147) is configured to be changeable in the reverse posture in which the normal posture and the front-rear direction are reversed.

In the threshing device 5 in general, abrasion of the trailing edge 148 of the front portion of the sweep 5a is large and abrasion of the trailing edge 148 of the sweeping 5a is small. This is because a cutting gap is supplied from the supply port 125 to the supply chamber 114 to perform a threshing process between the cut grooves at the front portion of the sweep 5a and to filter the throat process product from the water supply channel 117, 114 are less likely to be touched by the rear portion.

Therefore, according to this configuration, when the rod-like member (the raising frame 147) is initially placed in the normal posture and the abrasion of the front portion 148 of the rod-shaped member progresses, the rod- You can change the direction. Therefore, in the rod-like member of the worn-out portion 148 on which the abrasion has progressed, the worn-out portion 148 on which the abrasion has progressed is placed on the rear portion of the rod-like member, So that the entire service life of the rod-shaped member can be made long.

For example, in the case of changing the direction of the rod-shaped member, if the rod 148 is mounted over a plurality of adjacent rod-shaped members, the rod-like member to be changed in direction and the rod- The shape of the rod-like member to be changed in direction can not be changed unless the feedpiece 148 is removed. Further, if the trailing edge 148 is mounted over a plurality of adjacent bar-like members, it is necessary to change the direction of all of the plurality of bar-like members, and it is not possible to change the direction of one bar-like member.

On the other hand, according to this configuration, the trailing edge 148 protrudes outwardly from the rod-like member (the raising frame 147) in the form of a cantilever, and the distal end of the trailing edge 148 is opened The rod-like member can be independently changed in orientation without removing the spike 148. The rod-like member that does not need to be changed in direction It can be left in a normal posture.

It is also advantageous in that the feed dog 148 located at the front portion of the rod-like member is detachable and the feed dog 148 located at the middle portion of the rod-like member is not removable .

As described above, in the threshing device 5, wear of the trailing edge 148 of the front portion of the swash plate 5a is generally severe. On the other hand, according to this configuration, when the swash plate 148 of the front portion of the rod-shaped member (the swing frame 147) wears, the swash plate 148 of the front portion of the rod- The overall service life can be made long.

In this case, if the sprocket 148 is detachable, the structure of the sprocket 148 is complicated, so that not all of the sprockets 148 of the rod-like member can be detachably attached, It is possible to suppress the complexity of the structure of the rod-like member by configuring the feedwater 148 in the middle portion, which is slow in progress, to be non-removable.

In addition, a helical tooth portion (helical wing 143) for feeding back the cut tail portion to the rear side is provided at the front end portion of the swing 5a.

As described above, when the trailing edge 148 is formed in a circular shape in section, the function of conveying the traced edge or the processed product backward to the trailing edge 148 is unlikely to occur.

According to this configuration, since the helical teeth (helical wings 143) are provided at the front end of the ram 5a, the supply port 125 can be moved from the supply chamber 114 to the supply chamber 114, Can be prevented from being clogged by the stagnation of the cut-in curtain supplied from the supply port 125 to the supply chamber 114 .

In addition, a partition member (second plate 145) that separates the inner space of the ram 5a from the front and rear is provided. Therefore, it is possible to prevent the curled grains which have been made single-grain by the threshing treatment on the front side of the rake 5a by the partition member or to the downstream side in the threshing direction such as the inside of the inside of the rake 5a in the initial stage of the threshing treatment And the free ends of the free ends 5a and the free ends 5a are guided to the vicinity of the tilting 5a so that the free ends of the free ends 5a It is possible to prevent the occurrence of tertiary loss due to passing through the inner space and discharging from the downstream side end in the throttling treatment direction together with the deflagration gap.

Therefore, even when the throat-treated product is supplied in a large amount, sufficient threshing treatment can be performed on the throat-treated product without causing an increase in the load required for the thrashing treatment, It is possible to improve the threshing performance and the recovery efficiency of the grains while avoiding damages such as the racing 5a due to the increase in the load and the like. As a result, it is possible to improve the durability and the processing ability of the threshing device 5 (5a) structure.

Further, a winnowing fan 120 is installed to cause a selective wind, and the selective wind from the tuyeres is configured to flow toward the partition member (the second plate 145).

According to this configuration, the throat-treated product blocked by the partitioning member (second plate 145) is guided to the periphery of the partitioning member (around the pulsation 5a) by the selective air from the tuyeres 120, And flows toward the downstream side in the threshing direction from the periphery of the partition member along with the rotation of the sweep 5a, so that it is possible to avoid the possibility that the throat processing product will accumulate immediately before the partition member.

Therefore, it is possible to prevent the degradation of the processing ability due to the deposition of the throat-treated product.

It is also advantageous in the following respects that the rod-like member (the first frame 147) is detachably connected to the partition member (the second plate 145).

When the rod-like member is connected to the partition member, the rod-shaped member is supported by the support member in the front portion and the rear portion, So that the intermediate portion of the rod-like member is supported by the partition member, so that the rod-like member is supported with sufficient strength.

Therefore, when the rod-like member is configured to be changeable in the reverse posture in which the normal posture and the back-and-forth direction are reversed, according to this configuration, the rod-like member can be detachably attached to the partition member, Can be changed without any hindrance.

A dust conveyance valve (not shown) which has a top plate 124 for covering the upper side of the sweep 5a and guides backward the throat processed material conveyed to the upper portion of the middle chamber 114 in accordance with the rotation operation of the sweep 5a 149 is provided on the ceiling plate 124, it is advantageous in the following respects.

As described above, when the trailing edge 148 is formed in a circular shape in section, the function of conveying the traced edge or the processed product backward to the trailing edge 148 is unlikely to occur.

According to this configuration, by providing the dust transfer valve 149 on the ceiling plate 124 covering the upper side of the swash plate 5a, when the swash plate 148 is formed in a circular shape, So that it is possible to prevent clogging due to stagnation of the throat-treated product in the supply chamber 114. In addition,

It is advantageous in the following respects that the dust transfer valve 149 has a length extending to the right and left side edges of the ceiling plate 124.

As described above, in the case of providing the dust transfer valve 149 on the ceiling plate 124 covering the upper side of the swash plate 5a, according to this configuration, the dust transfer valve 149 is disposed on the left and right side edges And the dust transfer valve 149 is configured to be sufficiently long so that the throat processing article is guided rearward by the dust transfer valve 149 without further staying in the supply chamber 114 .

It is advantageous in the following respects that the top plate 124 is configured so as to substantially curve the trajectory K drawn by the leading end of the trailing edge 148 along with the rotation of the traction 5a.

As described above, in the case where the top plate 124 covering the upper side of the swing 5a is provided with the dust transfer valve 149, according to the present configuration, the top plate 124 is moved to the swing plate 148 The curled material is smoothly guided along the inner surface of the top plate 124 so that the throat processing product can smoothly guide the dust transfer valve 149 It is smoothly guided rearward.

Further, a water tube 117 is provided below the sweep 5a, and the mesh of the water tube 117 is formed into a rectangular shape long in the rotation direction of the sweep 5a.

In the case of the supply chamber 114, there are many throttled products which rotate together with the tilting 5a in accordance with the rotation of the tilting 5a. Thus, according to this configuration, the mesh of the water channel 117 positioned below the sweep 5a is formed into a rectangular shape having a long length in the rotating direction of the sweep 5a, So that the grains in the throat-treated product tend to be filtered from the mesh of the water tube 117.
