[1] The problem corresponding to the background art [1] is as follows.

In the combine, when clogging occurs in the harvesting section, if the harvesting section can be driven in a rotational direction opposite to the forward rotational direction driven at the time of work, the clogging can be easily eliminated.

In the case of employing the above-described conventional technique to enable the forward and reverse rotation driving of the harvesting section, the whole forward and reverse switching mechanism may be equipped with an electric case or a harvesting input shaft, or the reverse rotational power may be extracted from the driving electric system for harvesting. Equipped with a reverse rotation electric mechanism that transmits to the input shaft. Then, the cost tends to be high due to the production and equipment of the forward reverse switching mechanism and reverse reverse transmission mechanism. In addition, the overall structure of the transmission apparatus tended to be complicated.

An object of the present invention is to provide a combine that can perform the reverse rotation drive of the harvesting section at low cost and can be easily structured.

[2] The problem corresponding to the background art [2] is as follows.

When the above-mentioned conventional technique is employed to enable the reverse rotation driving of the harvesting section by switching between the forward rotation clutch and the reverse rotation clutch, the state in which the clutch operating tool is connected to the forward rotation clutch and the state in which the reverse rotation clutch is linked In order to link the clutch control mechanism with the clutch, a linkage mechanism having a complicated structure was required.

SUMMARY OF THE INVENTION An object of the present invention is that structure can be easily obtained from the aspect of the linkage between the clutch and the clutch operating tool, while being able to drive the harvesting unit forward and reverse in a state in which both the forward and reverse clutches are prevented from being operated in a connected state. To provide a combine.

[3] The problem corresponding to the background art [3] is as follows.

In the above configuration, since most of the processing chamber is used for the arrangement space of the barrel, and only the narrow space remaining around the barrel is used as the processing space for threshing treatment, a large amount of harvesting grain stems are used as the threshing processing material at the time of high speed work or the like. When supplied to, the processing space may be saturated, and when the saturation occurs, the threshing treatment material stays in the processing space, whereby the threshing treatment product is removed from the water network without sufficient threshing treatment being performed. It is easy to cause the problem of filtering down, the load required for threshing treatment, and the like, such that the electric system for the barrel is damaged.

An object of the present invention is to provide a rapid structure excellent in processing capacity capable of performing a sufficient threshing treatment on a threshing treatment product without causing an increase in the load required for the threshing treatment even when a threshing treatment product is supplied in a large amount. To provide a threshing apparatus having a.

[1] The means for solving the problem [1] is as follows.

It is a combine which mounted the threshing apparatus provided with the barrel and engine to a traveling body, and provided the harvesting part in the front part of the said threshing apparatus,

A front case of the threshing apparatus is provided with a case input shaft to which driving force from the engine is transmitted and a case output shaft in which the case input shaft is interlocked with the case input shaft via a bevel gear mechanism so as to transmit the driving force of the case input shaft to the barrel. Installed on the side,

Equipped with a mowing output shaft interlocked with the case input shaft via 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 for interlocking the case input shaft, the other side of the harvesting output shaft, and the harvesting input shaft so as to transmit a driving force in a reverse rotational direction to the harvesting input shaft of the harvesting section.

According to this configuration, when the forward rotation clutch is operated in the connected state and the reverse rotation clutch is operated in the released state, the driving force of the side of the case input shaft and the harvest output shaft to which the forward rotation clutch is interlocked is transmitted to the harvest input shaft. Then, since the rotation direction of a case input shaft and the rotation direction of a harvesting output shaft become the opposite rotation direction by a bevel gear mechanism, the harvesting input shaft is driven forward rotation.

On the other hand, when the forward rotation clutch is operated in the released state and the reverse rotation clutch is operated in the connected state, the driving force of the case in which the reverse rotation clutch is interlocked among the case input shaft and the harvesting output shaft is transmitted to the harvest input shaft. Then, since the rotation direction of a case input shaft and the rotation direction of a harvesting output shaft become the opposite rotation direction by a bevel gear mechanism, the harvesting input shaft is driven to reverse rotation.

As a result, even if a blockage occurs in the harvesting section, it is easy to drive the harvesting section in reverse rotation to eliminate the blockage, and the bevel gear mechanism can be obtained at low cost by using the rotational direction converting means, and the overall structure of the transmission is easily completed. You can get it as light as possible.

In one preferred embodiment, the case input shaft and the harvesting output shaft are arranged in the traveling body transverse direction with the barrel output shaft interposed therebetween.

According to this configuration, the case input shaft and the harvesting output shaft are arranged in a straight line or in a state close to the traveling body in the transverse direction of the traveling body, so that the size when viewed from the side of the traveling body of the transmission case can be made as small as possible.

As a result, it is possible to obtain a simple state in which the transmission case is compactly arranged on the front side of the threshing apparatus so that clogging is easily performed by driving the harvesting unit in reverse rotation.

In one suitable embodiment, it is comprised so that the said reverse rotation clutch may be hold | maintained by artificial operation in a connected state.

According to this structure, the thing which is easy to remove a blockage by reverse rotation drive of a harvesting part can be obtained in the state which is easy to avoid the trouble generation by the reverse rotation drive of a harvesting part.

That is, when the harvesting unit is driven in reverse rotation for a long time, an excessive force may be applied to the apparatus of the harvesting unit. According to the configuration of the third aspect of the present invention, it is necessary to consciously maintain the reverse rotation clutch in the connected state. This makes it easy to be careful not to make the reverse rotation drive of the harvesting section longer than necessary, such as intermittently performing a switching operation to the connected state of the reverse rotation clutch when driving the harvesting section in reverse rotation.

[2] The means for solving the problem [2] is as follows.

It is a combine which mounted the threshing apparatus provided with the barrel and the engine to a traveling body, and provided the harvesting part in the front part of the said threshing apparatus,

A forward rotation clutch for transmitting a forward rotational driving force to the harvesting unit, and a reverse rotation clutch for transmitting a reverse rotational driving force to the harvesting unit,

A forward rotation clutch operation port for switching the forward rotation clutch and a reverse rotation clutch operation port for switching the reverse rotation clutch, respectively,

When the forward rotation clutch is in the connected state, the switching operation to the connected state of the reverse rotation clutch is switched to a check state, and when the forward rotation clutch is in the release state, the state is switched to the release state in which the check is released. The combine which installs a check mechanism.

According to this structure, even if it tries to switch a reverse rotation clutch to the connection state in the state which made the forward rotation clutch connected, the reverse rotation clutch does not switch to a connection state by the action of a check mechanism. Then, even if the forward rotation clutch operating port for switching the forward rotation clutch and the reverse rotation clutch operation port for switching the reverse rotation clutch are respectively provided, the forward rotation clutch is connected and the reverse rotation clutch is connected. Can not. Thereby, the forward rotation clutch and the forward rotation clutch operation tool as its operation tool can be linked at all times, and the reverse rotation clutch and the reverse rotation clutch operation tool as its operation tool are always linked. Can be.

Therefore, it is possible to drive the harvesting unit forward and reverse while preventing the reverse clutch from being switched to the connected state while the forward clutch is in the connected state. A simple thing can be obtained inexpensively.

In one suitable embodiment, the check mechanism is provided with a check body integrally supported on one side of the forward clutch operating tool and the reverse clutch operating tool, and the other side of the forward clutch operating tool and the reverse clutch operating tool. It is comprised so that a switch to the connection state of a reverse rotation clutch may be prevented by checking a switch to the connection position of the said reverse rotation clutch operation tool by a contact with a contact part.

According to this structure, a check mechanism can be obtained by the simple structure which supports a check body integrally rocking to one of a forward clutch control tool and a reverse clutch control tool, and installs a contact part in the other side of a forward clutch control tool and a reverse clutch control tool. Can be.

Therefore, it is possible to drive the harvesting unit forward and reverse while preventing the reverse clutch from being switched to the connected state while the forward clutch is in the connected state, not only in terms of the coupling between the clutch and the operating tool, but also in terms of the check mechanism. A simple thing can be obtained inexpensively.

[3] The means for solving the problem [3] is as follows.

It is threshing apparatus mounted in combine,

It is equipped with the barrel which performs threshing process with respect to the harvesting grain stem supplied to the processing chamber by rotationally driving by using the support shaft as a support point,

A plurality of rod-shaped members arranged so as to be arranged such that the barrels are spaced apart at a predetermined interval in the circumferential direction of the barrels in a posture along the support shaft, and support members provided before and after the support shaft to support the rod-shaped members; Threshing, characterized in that each of the rod-shaped members is configured with a plurality of rapid teeth arranged to be spaced apart from each other in a front-rear direction by a posture protruding from the rod-shaped member toward the outside of the barrel. Device.

According to this configuration, the barrel has a space communicating therein with the feeding chamber, thereby allowing the introduction of the threshing treatment material into the interior space. Therefore, during the rotation operation, the threshing process by a plurality of rod-shaped members, hitting or skimming of the plural bar members, is performed to the threshing process around the threshing process and the threshing process introduced into the inner space. Done.

That is, even when a large amount of harvesting grain stem is supplied to the feeding chamber as the threshing treatment product, the inner space of the barrel can be effectively used as the treatment space for the threshing treatment, so that the staying of the threshing treatment product in the treatment space and the saturation of the treatment space are avoided. can do. As a result, the problem that the threshing process is filtered out from the water network without sufficient threshing treatment due to the retention of threshing process or the saturation of the processing space, and the load required for the threshing treatment are increased, and the transmission to the barrel is increased. It is possible to avoid the occurrence of problems such as damage to the system.

In addition, by arranging the plurality of rod-shaped members so as to be spaced apart at a predetermined interval in the circumferential direction of the barrel, it is possible to prevent the winding of the long straw on the rod-shaped members, thereby preventing the retention of the threshing treatment material due to the winding. Can be avoided. In addition, during the rotational operation of the barrel, not only a plurality of jets but also a plurality of rod-shaped members forming the barrel body of the barrel function as a threshing processing member that performs threshing processing by thrashing or sweeping against the threshing process. The threshing performance can be improved.

In addition to the above configuration, if the barrel is equipped with a partition member that spaces the inner space back and forth, it is further advantageous in the following points.

According to this characteristic constitution, the grains separated by the threshing process on the front part side of the barrel by the partition member, or the flow to the threshing direction in the downstream direction, such as the non-tallip grain stem introduced into the internal space of the barrel in the initial stage of the threshing process, are flowed. This is suppressed, and the granulated grains, the untapped grain stems, and the like are guided around the barrel with the rotation of the barrel, so that the grained grains, the untapped grain stems, etc., just pass the internal space of the barrel and are separated. The occurrence of tertiary loss caused by discharge from the downstream end in the threshing treatment direction together with the grain stem can be prevented.

Therefore, even when a threshing process material is supplied in large quantities, sufficient threshing process can be performed with respect to threshing process material, and the generation | occurrence | production of 3rd loss is prevented, without causing the increase of the load required for threshing process. As a result, the threshing performance and the grain recovery efficiency can be improved while avoiding damage to the hydraulic power system due to the increase in load, and as a result, the barrel structure of the threshing apparatus with excellent durability and processing ability can be provided. .

In addition, it is further advantageous in the following point if it is equipped to equip the winnowing fan which produces the sorting wind, and to flow the sorting wind from the said blowing opening toward the said partition member.

According to this characteristic structure, the threshing process block | blocked by the partition member is scattered up and down toward the periphery (circumference | surroundings of a barrel) of the partition member by the sorting wind from a tuyere, and threshing process from the surroundings of a partition member with rotation of a barrel. Since it flows toward the downstream direction, the possibility of threshing processed material deposited at the site | part immediately before a partition member can be avoided beforehand.

Therefore, the fall of the processing ability resulting from the deposition of threshing process material can be prevented.

In one suitable embodiment, the upper side of the said barrel is covered by the ceiling plate, and the said ceiling plate is equipped with the some dust conveying valve which guides the said harvesting grain stem toward the threshing process direction downstream according to the rotational drive of the said barrel. .

According to this characteristic constitution, the harvesting grain stem supplied to the processing chamber is conveyed toward the upper part of the processing chamber and receives the threshing action due to the plural hits and skippings due to the rotation of the barrel. Therefore, it is guided toward the threshing process direction downstream by a some dust feed valve.

That is, the threshing processing material can be conveyed to the threshing process direction downstream, provided that a some raw material is provided in a barrel, and sufficient threshing action | action by hitting or skipping of the threshing process with respect to threshing process material is fully acquired.

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 making the dust conveyance valve convey mainly to the threshing process direction downstream of a threshing process material, the threshing performance and grain recovery efficiency can be improved, without impairing the conveyance performance of the threshing process object toward a downstream threshing process direction. It is possible to provide the threshing structure of the full width input combine combine.

If the said dust conveying valve is formed so that it may have length over the left and right edge parts of the said ceiling board, the length of the dust conveying valve equipped with a ceiling board can be made long enough, and this is downstream of the threshing process direction by a dust conveying valve. The conveyance guide of the threshing process object toward the side can be made more favorable. Therefore, the conveyance performance of the threshing process object to the threshing process direction downstream can be improved, aiming at the improvement of threshing performance by a plurality of processing values, and grain recovery efficiency.

Moreover, if the said ceiling plate is formed so that the rotational trace which the tip of the said tooth may draw according to the rotation of the barrel may be curved substantially, the threshing process conveyed to the upper part of the chamber will be rotated according to the rotation of the barrel, and the ceiling plate and the dust conveying valve. It can be guided smoothly downward below the threshing process direction, making it follow. Therefore, while improving the threshing performance and grain recovery efficiency by a plurality of jets, it is possible to improve the conveyance performance of the threshing treatment product toward the downstream side of the threshing treatment direction. Damage and the like can be avoided.

In one suitable embodiment, the front-end part of the said barrel is equipped with the spiral blade which conveys the harvested grain stem supplied and conveyed toward the front-end part toward the back according to the rotation of the said barrel, and makes the said spiral wing detachable. I wear it.

According to this characteristic configuration, when the spiral blade is remarkably worn by severe contact with a harvesting grain stem or the like over a long period, only the worn spiral blade can be replaced. As a result, compared to the case where the spiral blades are not detachably mounted by welding or the like, the effort and the cost required for the replacement of the spiral blades can be greatly reduced. As a result, the worn spiral blades can be reduced. It becomes easy to exchange. Then, it becomes easier to replace the worn spiral blades, thereby reducing the soot conveyance action of the spiral blades to the harvesting grain stem, which is caused when the wear of the spiral blades is left untreated. Problems such as a decrease in capability can be easily avoided.

Therefore, by implementing a simple improvement such as detachably attaching the spiral blade to the shear front end portion, it is possible to easily and inexpensively perform appropriate treatment for the wear of the spiral blade, and as a result, wear of the spiral blade It can be made easy to avoid the fall of the threshing process ability resulting from this.

In addition to this configuration, the bottom of the barrel is disposed so as to cover the front end of the barrel from below, so that the harvested grain stem supplied and conveyed toward the front end of the barrel is picked up, and the bottom grain stem is conveyed by the spiral blade. If the conveyance assistance guide is provided so that the conveyance assistance guide can be attached or detached at least the part located in the rotational direction downstream of the said barrel, the conveyance assistance guide will severely contact with harvesting grain stems etc. over a long term. When it is remarkably worn by, only the worn conveyance auxiliary guide can be replaced. Thereby, compared with the case where the conveyance assistance guide is attached to a support frame or the like by welding or the like, for example, it is possible to significantly reduce the labor and cost required for the replacement of the worn conveyance assistance guide. As a result, It becomes easy to replace the worn conveyance auxiliary guide. And it becomes easy to replace the worn conveyance auxiliary guide, and the cutting gap is large because the clearance gap formed between the spiral blade and the conveyance auxiliary guide becomes large, which is caused when the wear of the conveyance auxiliary guide is left unattended. The problem that the conveyance of the spiral of a spiral blade | wing to a grain stem falls, and the threshing process ability falls with that fall can be easily avoided.

By the way, the harvesting grain stem etc. conveyed by the spiral blade to the rear according to rotation of a barrel are gathered in the rotation direction downstream part of a barrel in a conveyance auxiliary guide under the influence of a rotation of a barrel. Therefore, in the conveyance auxiliary guide, the portion located on the downstream side in the rotational direction of the barrel is in deeper contact with the harvesting grain stem and the like, and wear due to the contact tends to occur.

Therefore, in view of that point, when the rotational direction downstream side part of the barrel in a conveyance auxiliary guide is detachably detachable, it is downstream of the barrel in the conveyance auxiliary guide by severe contact with the harvesting grain stem etc. over a long term. If the side part is worn out remarkably, only the worn part can be replaced. Thereby, compared with the case where the whole conveyance assistance guide is replaced, the cost required for exchange | exchange can further be reduced.

Therefore, by carrying out a simple improvement such that the conveyance assistance guide is configured such that at least the portion located at the downstream side in the rotational direction of the barrel becomes detachable, appropriate treatment for wear of the conveyance assistance guide can be performed simply and inexpensively. As a result, it is possible to easily avoid a drop in threshing treatment capability due to wear of the conveyance auxiliary guide.

In one suitable embodiment, it is formed so that a water net may be arrange | positioned so that the said barrel may be covered from below, the ceiling plate may be arrange | positioned so that the said barrel may be covered from above, and it has a guide surface which connects those inner surfaces in series between the said net and the said ceiling plate. Equipped with a detachable member detachably.

According to this characteristic configuration, when the guide surface of the joint member is remarkably worn by severe contact with the harvesting grain stem and the like over a long period, only the worn joint member can be replaced. Thereby, compared to the case where the joint member is unremovably mounted on the mesh or ceiling plate by welding or the like, the labor and cost required for the replacement of the worn joint member can be greatly reduced, and as a result, the worn joint It becomes easy to exchange a member. And it becomes easy to replace the worn joint member, and it becomes impossible to connect the inner surface of a water net and the inner surface of a ceiling plate in series by the guide surface of a joint member, which is caused when the wear of a joint member is left unattended, Due to the fact that the harvesting grain stem and the like do not flow smoothly over the barrel of the barrel and the ceiling plate, problems such as deterioration of the threshing processing ability can be easily avoided.

Therefore, by implementing a simple improvement such as detachably mounting the joint member between the mesh and the ceiling plate, it is possible to easily and inexpensively perform appropriate treatment for the wear of the joint member. As a result, wear of the joint member can be achieved. It can be made easy to avoid the fall of the threshing process ability resulting from this.

Then, the tension restrictor 97 supports the tension ring 94 through the support shaft 99 so as to resist movement against the spring 92 of the tension ring 94. As a result, the tension restrictor 97 prevents a significant loosening from the guide wheel body 89 in the portion 44b which becomes the relaxed side of the electric chain 44 due to the reverse rotational drive of the harvesting section 10. The relaxation margin of this part 44b is suppressed.

11-13, the feeding chamber 114 is formed in the upper part of the threshing apparatus 5. As shown in FIG.

In the lower part of the sheave case 129, the grain pan 133 and the grain sheave 134 for fine sorting are arrange | positioned from the front side of the sheave case 129 in that order. In the upper portion of the swing sorting mechanism 119, the sorted object filtered out from the water net 117 in a state where granulated grains, straw crumbs, etc. are mixed, is disposed on the upper grain pan 130, the chives 131 or the straw. It picks up by the rack 132, and performs the initial screening process by sifting. In the lower part of the swing sorting mechanism 119, the sorting processing material filtered out from the chaff sieve 131 in the state which the granulation grain, the grain with a stem, etc. are mixed, and the lower grain pan 133 and the grain sheave 134 are carried out. ), And perform the precise sorting process by sifting. As a result, the sorted material was separated into granulated grains as the first crop, mixed grains such as grains and straw crumbs as the second crop, and straw as the third crop. We sort by dust such as debris.

The tuyere 120 is driven from the engine 20 transmitted through the belt transmission mechanism 25, and rotates around the tuyere drive shaft 26 as a support point to generate the sorting wind. The sorting wind is supplied to the sorting material filtered out from the water network 117 through the three air paths R1 to R3 and to the sorting material sorted by the swinging sorting mechanism 119, whereby the specific gravity is increased from the sorting material. Small straw waste etc. are scattered here and there and conveyed toward the discharge port 123 downstream of a threshing process direction. The first recovery unit 121 filters the granulated grains filtered out from the grain sheave 134 of the swinging sorting mechanism 119 in the state where dust such as straw flakes is removed by the sorting wind from the tuyere 120.

The conveying screw 137 conveys the 1st conveyed from the 1st screw conveyor 28, and supplies it to the packaging tank 6a provided in the upper part of the grain packaging part 6 (refer FIG. 1 and FIG. 2). The second reduction mechanism 139 is provided with a reprocessing unit (not shown) which performs threshing treatment again with respect to the second article conveyed by the second screw conveyor 29, and performs the second article after the threshing treatment by the reprocessing section. It is transported and reduced to the swinging screening mechanism 119 (see FIGS. 2 and 11).

The discharge port 123 is equipped with a grained grain stem flowing down from the straw discharge port 118 without being filtered down from the water net 117, or straw debris that is sorted and conveyed to the rear of the swing sorting mechanism 119 by a sieve sorting process or a wind sorting process. Radiate out.

As shown in FIGS. 11-17, the barrel 5a is a truncated truncated grapple part 141 which forms the front-end part, and the skipping process part 142 connected to the rear end of the grapple part 141. As shown to FIG. It is equipped with. On the outer circumferential surface of the chamfer 141, the harvesting grain stem supplied and conveyed to the supply port 125 by the feeder 11 is gathered and conveyed toward the sweeping processor 142 at the rear in accordance with the rotation of the barrel 5a. Two spiral blades (an example of spiral teeth) 143 are equipped.

The skipping process part 142 is the 1st plate (an example of a support member) 144 which was integrally equipped in the front part of the threshing output shaft 38, and the 2nd plate (compartment member) which was integrally equipped in the front-back middle part of the threshing output shaft 38. 145), the front-back direction along the threshing output shaft 38 by the 3rd plate (an example of a support member) 146 integrally equipped in the rear end of the threshing output shaft 38, and those plates 144-146. In the postures of six barrel frames (an example of a rod-shaped member) 147 and each barrel frame 147 made of round pipe steel or the like supported so as to be arranged at a predetermined interval apart in the circumferential direction of the barrel 5a, It is a posture which protrudes toward the outer side of the barrel 5a from the barrel frame 147, and is comprised by the several tooth gear 148 etc. which were equipped so that it might arrange | position at predetermined intervals in the front-back direction.

That is, the barrel 5a is arranged so that the plurality of jets 148 protruding toward the outside thereof are arranged so as to be spaced apart from each other in the circumferential direction and the front-rear direction of the sweeping processing unit 142 by a predetermined interval. In addition, the barrel 5a is formed so that the internal space S of the skimming part 142 communicates with the quick delivery chamber 114, and allows the processing object to be taken into the internal space S. FIG. As a result, during the rotational operation of the barrel 5a, while the workpieces around it and the workpieces introduced into the internal space S are stirred, the impacts of the barrel frame 147 and the pier 148 on the processed objects are Threshing process by sweeping etc. is performed.

In addition, when the internal space S of the sweeping processing unit 142 communicates with the feeding chamber 114, even when a large amount of harvesting grain stem is supplied to the feeding chamber 114 as a processing object, the internal space S of the sweeping processing unit 142 is used. ) Can be effectively used as a processing space for threshing treatment. As a result, it is possible to avoid the retention of the processed material in the processing space and the saturation of the processing space. As a result, the processed material is filtered out from the water network 117 or the load required for the threshing process is increased in a state in which sufficient threshing treatment is not performed due to the retention of the processed material or the saturation of the processing space. It is possible to avoid problems such as breakage of the electric system for the power supply.

In the rotation operation of the barrel 5a, not only the plurality of jets 148 but also the six barrel frames 147 forming the skid processing section 142 of the barrel 5a as a skipping processing member acting on the workpiece. As a result, the threshing performance and threshing efficiency can be improved.

In addition, inside the barrel 5a in the front and rear intermediate portions of the barrel 5a in which a large amount of grains are separated by the threshing treatment on the front side of the barrel 5a, and the amount of processing water is reduced by filtering out from the water net 117. The second plate 145 spaced apart from the space S back and forth prevents the flow of the processed material in the inner space S of the barrel 5a to the downstream side in the threshing treatment direction, and is processed together with the rotation of the barrel 5a. Water is guided around the barrel 5a to promote threshing and filtering down from the net 117 of the granulated grains by hitting or sweeping the jet 148 or the like against the treated material. As a result, the straw discharge port 118 formed by the granulated grains, the ungrained grain stems, etc. contained in the processed material just passed the internal space S of the barrel 5a and formed at the downstream end in the threshing process direction together with the grain break grains. It is possible to prevent the occurrence of the third loss by discharge from the.

In addition, at the time of the rotation operation of the barrel 5a, the outside air sucked from the supply port 125 in accordance with the rotation of the spiral blade 143 together with the harvesting grain stem that is gathered and conveyed by the action of the grapple 141, It flows smoothly to the circumference | surroundings of the barrel 5a and the internal space S of the skipping process part 142. FIG. Thereby, the outflow to the feeder 11 can be prevented from the supply port 125, such as the straw waste which generate | occur | produced by the threshing process, and conveyance of a processed material downstream of the threshing process direction can be performed faster.

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 includes a mowing device 16, an auger 18, and the like. Since the discharge port (not shown) and the supply port 125 for collection | recovery grain stem conveyance formed in the harvest collection part of the harvesting | reaping conveying apparatus 4 equipped with this are made to communicate, the spiral blade | wing at the time of rotation operation of the barrel 5a is carried out. Due to the suction action of the rotation of the 143, the dust and the dust of straw debris generated by the mowing and recovery processing in the mowing recovery unit, the outside space and the internal space of the feeder 11 from the outlet of the mowing recovery unit together with the outside air. Through 125, it flows into the circumference | surroundings of the barrel 5a and the internal space S of the skipping process part 142. As shown in FIG. As a result, it is possible to suppress adhesion deposits and flying up, such as straw crumbs, in the harvest recovery section, and to reduce the conveyance of the cutting grain stems resulting from the adhesion deposits, and to reduce the working environment and visibility due to the flying up. It can be suppressed.

Each plate 144-146 is circular centered around the threshing output shaft 38, and the barrel frame 147 is bolted to the equidistant position from the threshing output shaft 38 in the outer peripheral side. That is, six barrel frames 147 are arranged on the outer circumferential side of each of the plates 144 to 146 in a state of being spaced apart at regular intervals in the circumferential direction thereof to increase the body diameter of the barrel 5a. . Thereby, the winding of the harvesting grain to the barrel 5a can be prevented.

Each barrel frame 147 is changeable and adjacent to a normal posture in which its front and rear directions coincide with the front and rear directions of the barrel 5a, and inverted in its reverse direction in which its front and rear directions are opposite to the front and rear directions of the barrel 5a. It is bolted to each plate 144-146 so that the front-back direction with the barrel frame 147 may be reversed.

Each of the barrel frames 147 is provided with a plurality of mounting holes 147A and 147B for enabling the mounting of the tooth teeth 148 at a constant pitch P in the front and rear directions thereof. The distance L1 from the front end to the center of the front mounting hole 147A and the distance L2 from the rear end of the barrel frame 147 to the center of the rearmost mounting hole 147A are half pitch (= 1 / 2P). It is perforated in a different state as).

And each barrel frame 147 is connected and supported by each plate 144-146 in the state in which the front-back direction with the adjacent one is reversed. Thereby, while employ | adopting the thing of the same structure as the six barrel frames 147, the gear teeth 148 equipped in each of the barrel frames 147 are moved in the front-back direction with the barrel teeth 148 of the adjacent barrel frames 147. The position can be shifted by half pitch. As a result, it is possible to reduce the striking interval of the steer 148 against the workpiece without reducing the spacing of the adjacent steer 148.

That is, while reducing the cost by having each of the barrel frames 147 in the same configuration, the smaller the interval between the adjacent tooth teeth 148, the easier it is to bring about. It is possible to improve the threshing performance by increasing the number of strikes of the plunging tooth 148 against the processed material while effectively preventing clogging of the processed material due to the winding.

In addition, since each barrel frame 147 is equipped so that a direction can be changed into a normal posture and an inverted posture, the abrasion of the jet 148 located in the threshing process direction upstream which is relatively easy to be worn by a large amount of processing volume is used for a long time. In this case, when the remarks are remarked, the plurality of quick teeth 148 provided in the quick frames 147 are relatively easy to be worn by changing the directions of the quick frames 147, and the fast teeth 148 on the upstream side of the threshing process direction which tend to be relatively worn. And position can be changed at once in the state which replaced the processing gear 148 downstream of the threshing process direction which is hard to be worn. As a result, the feed value 148 on the downstream side of the threshing process direction with less wear can be effectively used as the feed value 148 on the upstream side of the threshing process direction with a large amount of processing water.

Of the plurality of mounting holes 147A and 147B, four mounting holes 147A located at both front and rear ends of each barrel frame 147 are smaller in diameter than the mounting holes 147B located in the middle portion. It is formed.

Of each of the teeth 148, the teeth 148A to be mounted using the small-diameter mounting holes 147A are stepped round bar steels provided with small diameter portions 148a to be inserted into the mounting holes 147A. It is comprised so that the center of the threshing output shaft 38 and the line which passes through the center of the barrel frame 147 can be detachably attached to the barrel frame 147 by the nut.

The feed 148B, which is mounted using the mounting hole 147B in the middle portion, is composed of a round bar steel without a step, the center of which is positioned on a line passing through the center of the threshing output shaft 38 and the center of the barrel frame 147. The welding is performed on the barrel frame 147 in a non-removable manner.

That is, since each of the teeth 148A located at the front and rear ends of the skid processing part 142 is detachable, when the teeth 148A are remarkably worn out by long-term use including the change of the direction of the barrel frame 147, Can be easily replaced with a new jet 148A.

Moreover, on the downstream side in the threshing process direction which increases the amount of threshing grain stem, as shown in FIG. 18, when arrange | positioning in the state which squeezed the swift teeth 148A located in the rear end part of the barrel 5a, The spacing of the gear 148A becomes large, and it is possible to effectively suppress the retention of the delamination grains caused by the latch on the gear 148A at the rear end portion of the barrel. As a result, it is possible to promote the release of the granulated grain stem from the straw outlet 118.

The mesh is configured to have a long horizontally long rectangular shape in the rotational direction of the barrel 5a. Thereby, compared with the case where the mesh 117 is comprised so that the mesh may become a long vertically long rectangular shape in the threshing process direction (front and rear direction) of the barrel 5a, a siphoning grain etc. of the mesh 117 It becomes easy to be filtered out from the front part side. As a result, generation | occurrence | production of the peeling grains resulting from suppressing the filtering of the granulation grains from the front part side of the water net 117 can be suppressed effectively. In addition, by forming each of the receiving members 153 in the same shape, the productivity and the assembly adhesion of the receiving member 117 can be improved.

As shown in Figs. 11 and 24, the chief sieve 131 for priming selection is a single sorting plate 154 bolted to the sheave case 129 in a rear upwardly inclined posture positioned upwardly downstream of the sorting direction. It consists of).

On the front side of the sorting plate 154 (an area of about one third of the front side relative to the whole of the sorting plate 154), a plurality of filtering holes 154A formed in a rectangular shape in plan view are provided in the front row. The rear row of filtering holes 154A are arranged in a zigzag shape between the filtering holes 154A. On the rear side of the sorting plate 154 (the area about 2/3 of the back side relative to the whole of the sorting plate 154), a plurality of filters formed in a rectangular shape when viewed in a plane having the sorting pieces 154a and 154b. Lowering holes 154B and 154C are formed in a zigzag shape in which rear rows of filtering holes 154B and 154C are located between front rows of filtering holes 154B and 154C.

Among each sorting piece 154a, 154b, the sorting piece 154a located in the left-right center side of the sorting plate 154 is cut out and formed in the scale shape located upwards narrower as the downstream of the sorting direction. The sorting piece 154b located at the left and right both ends of the sorting plate 154 has a shorter rectangular shape than the sorting piece 154a at the left and right center side, and is formed by being punched out so as to be located upward in the sorting direction downstream. have.

That is, since the chives sheave 131 for the primary sorting is constituted by a single sorting plate 154, for example, the chives sheave 131 is arranged to be spaced apart at a predetermined interval in the front-rear direction by a plurality of charips made of a strip-shaped steel sheet. Compared with the case where the arrangement is made, the configuration can be simplified and the cost can be reduced.

And the sieve 131 which formed the filtering hole 154A which is not equipped with the sorting pieces 154a and 154b in the front part side of the chaff sheave 131 to which the sorting object with a high content of a granulation grain is supplied is provided, The granulation grain which falls down by the grain pan 133 and grain sheave 134 of the downward from the front part side of () increases. As a result, the recovery rate of the granulated grains in the 1st collection part 121 located below the grain pan 133 and the grain sheave 134 can be improved.

Further, in the sifting treatment, the sieve sieve is formed by rearranging the filtering holes 154B and 154C having the sorting pieces 154a and 154b on the rear side of the chaff sheave 131 in a zigzag shape. The sorting processing on 131 is distributed evenly without bias in the left and right directions. Thereby, filtering down from each filtering hole 154B, 154C of a granulation grain can be promoted.

Moreover, by equipping the chaff sheave 131 in the rearward inclined posture, the chaff sheave 131 uses the sorting treatment in the sifting treatment as compared with the case of equipping the chaff sheave 131 in the horizontal posture. The force which pushes toward the upper side of the sorting process direction upstream becomes large. Therefore, at the time of sifting, the conveyance to the downstream of the sorting direction of the sorting processing is suppressed, and the vertical movement of the sorting processing is increased and the specific gravity difference sorting of the sorting processing is performed more effectively, thus filtering every grain of a large specific gravity. Filtering from the lowering holes 154B and 154C is promoted, and the occurrence of the third loss in which the granulated grains are discharged out of the device from the discharge port 123 can be effectively suppressed, and as a result, the improvement of the grain recovery efficiency can be improved. We can plan.

In addition, the sorting pieces 154b at the left and right ends of the chaff sheave 131 are formed shorter than the sorting pieces 154a at the left and right center side, so that the sorting processing material in the chaff sheave 131 is deposited. Filtering, such as a grain, from the filtering hole 154C of an easy left and right both ends can be accelerated | stimulated. As a result, the fall of the sorting efficiency resulting from the deposition of the sorting processing material at the left and right ends of the chaff sheave 131 can be avoided.

In addition, the ratio of the filtering hole 154A which is not provided with the sorting piece 154a and 154b formed in the chaff sheave 131 and the filtering hole 154B and 154C provided with the sorting piece 154a and 154b is shown. The silver can be changed in various ways depending on the type of grain to be sorted.

In addition, on the front side of the sorting plate 154, a plurality of sorting holes 154C formed in a rectangular shape in plan view so as to have a rectangular sorting piece 154b in a short direction, the sorting hole 154C in the front row. You may make it arrange | position to the zigzag shape in which the rear hole filtering hole 154C is located in between.

As shown in FIG. 11, the sorting wind which passes through the wind path R1 of the upper end among the sorting winds from the tuyere 120 of the barrel 5a through the wind path R4 formed in the sheave case 129. It is set to flow toward the second plate 145. Thereby, the processed material to which the flow to the threshing process direction downstream side is prevented by the 2nd plate 145 can be conveyed by wind toward the periphery of the barrel 5a. As a result, it is possible to avoid the fear that the processed material is deposited at the immediately preceding portion of the second plate 145, thereby causing trouble in the threshing process.

As shown in FIG. 11 and FIG. 14, the barrel 5a has a rapid traverse 148A located at the rear end thereof so as to face the straw discharge port 118 behind the rear end of the water net 117. . That is, in the rear end of the barrel 5a, the water net 117 does not exist, and a relatively large space is formed around it. As a result, even if the detached grain stem is wound around the spigot 148A of the barrel rear end portion, the detached grain stem is released from the tip of the spigot 148A by the centrifugal force caused by the rotation of the barrel 5a. As a result, it is possible to effectively suppress the retention of the peeling grain stem resulting from the engagement of the spigot 148A at the rear end of the barrel 5a, and to promote the discharge from the straw outlet 118 of the peeling grain stem.

As mentioned above, in this invention, the threshing apparatus provided with the barrel 5a which threshes with respect to the harvesting grain stem supplied to the processing chamber 114 by being rotationally driven with the support shaft (the barrel output shaft 38) as a support point ( 5) WHEREIN: The several cross-section circular rod-shaped member (barrel frame 147) arrange | positioned so that the barrel 5a may be arrange | positioned at predetermined intervals in the circumferential direction of the barrel 5a in the posture along a support shaft, The cantilever beam toward the outside of the barrel 5a from the rod-shaped member on each of the support members (first plate 144, third plate 146) provided before and after the support shaft to support the rod-shaped member. It consists of a plurality of cross-sectional circular feeders 148 which are arranged to be spaced apart at a predetermined interval in the front-rear direction by a posture protruding in a shape.

According to this configuration, the barrel 5a has a space communicating therewith with the feeding chamber 114, thereby allowing the introduction of the threshing treatment material into the interior space. Therefore, at the time of the rotational operation, a plurality of rod-shaped members (buckling frame 147) and the feed 148 are stirred for the threshing processed material and the threshing processed material introduced into the inner space while stirring. Threshing process by hitting or skipping is performed.

That is, even when a large amount of harvested grain stem is supplied to the processing chamber 114 as the threshing treatment product, since the internal space of the barrel 5a can be effectively used as the processing space for threshing treatment, Saturation of the processing space can be avoided. As a result, the problem that the threshing process is filtered out from the water network without sufficient threshing treatment due to the retention of threshing process or the saturation of the processing space, and the load required for the threshing process are increased, resulting in a sudden increase in the load 5a. It is possible to avoid the occurrence of a problem such as damage to the electric system.

In addition, by arranging a plurality of rod-shaped members (barrel frames 147) so as to be spaced apart at a predetermined interval in the circumferential direction of the barrel 5a, winding of long straw on the rod-shaped members can be prevented, Retention of the threshing process due to the winding can be avoided. In addition, in the rotation operation of the barrel 5a, not only the plurality of jet teeth 148 but also a plurality of rod-shaped members forming the trunk portion of the barrel 5a are subjected to threshing treatment by hitting or sweeping the threshing process. Since it functions as a threshing process member, the threshing performance can be improved.

In addition, since the rod-shaped member (the barrel frame 147) and the teeth 148 are formed in a circular cross section, the rod-shaped members and the teeth 148 have fewer portions such as sharp corners. It is less likely that threshing processing material is damaged by the hit of (148).

In addition, the jet 148 protrudes in a cantilever shape from the rod-shaped member (the barrel frame 147) to the outside, and the tip end of the jet 148 is in an open state (not connected to any member). Therefore, the threshing process wound around the pier 148 is easily moved outward along the pier 148 by the centrifugal force by the rotation of the barrel 5a, and is in a state of being easily separated from the distal end of the pier 148. The state such that the threshing processed material is not wound by being wound around the feed 148 is reduced.

In addition, it is advantageous from the following points that the rod-shaped member (the barrel frame 147) is configured to be changeable in an inverted posture in which the normal posture and the front-back direction are reversed.

In the threshing apparatus 5, the abrasion of the jet 148 of the front part of the barrel 5a is severe, and the abrasion of the jet 148 of the back part of the barrel 5a is small. This is a harvesting grain stem supplied from the supply port 125 to the processing chamber 114, the threshing process of the harvesting grain stem is mainly performed in the front part of the barrel 5a, and the threshing process material is filtered off from the water network 117, This is because the cutting grain stem which is not threshing becomes smaller as it goes to the rear part of 114).

Therefore, according to this structure, initially, the rod-shaped member (the barrel frame 147) is put in the normal posture, and when the wear of the plunging teeth 148 of the front portion of the rod-shaped member proceeds, the rod-shaped member is placed in the reverse posture. You can change the direction. Therefore, in the rod-shaped member of the wear-in progress 148, the wear-in progress 148 is placed at the rear of the rod-shaped member, and the wear-in-progress 148 is placed in front of the rod-shaped member. It can be located in the part, and the whole service life of a rod-shaped member can be made long.

For example, if the gear 148 is mounted over a plurality of adjacent rod-shaped members, when the rod-shaped member is changed in direction, the rod-shaped member to be changed in direction and the rod-shaped member that does not need to be changed in direction. If the gear 148 is attached, the direction of the rod-shaped member which should be changed in direction cannot be changed unless the gear 148 is removed. In addition, when the gear 148 is attached over the adjoining several rod-shaped member, it is necessary to change the direction of all these rod-shaped members, and cannot change direction of one rod-shaped member independently.

On the other hand, according to this structure, the toothed tooth 148 protrudes in a cantilever shape from the rod-shaped member (the barrel frame 147) to the outside, and the front end of the toothed tooth 148 is open (connected to any member, And the rod-shaped member which does not need to change the direction, since one rod-shaped member can be changed in direction alone without removing the gear 148, when the direction of the rod-shaped member is changed. It can be left in a normal position.

In addition, it is advantageous in the following point that it is possible to detach | demount the feed value 148 located in the front part of a rod-shaped member, and to comprise the feed value 148 located in the middle part of a rod-shaped member so that attachment or detachment is impossible. .

As described above, in the threshing apparatus 5, the abrasion of the jet 148 of the front part of the barrel 5a is generally severe. On the other hand, according to this structure, when abrasion of the feed 148 of the front part of a rod-shaped member (the barrel frame 147) advances, it replaces the feed 148 of the front part of this rod-shaped member, The whole service life can be made long.

In this case, if the salvage 148 is configured to be detachably attached, complexity of the structure is accompanied. Therefore, not all the salvage 148 of the rod-like member is detachably configured, but rather than the front portion of the rod-shaped member, By making the piercing part 148 of a middle part which advancing slow detachably, complexity of the structure of a rod-shaped member can be suppressed.

Moreover, the spiral tooth part (spiral blade 143) which conveys the mowing grain culm back to the front end of the barrel 5a is provided.

As described above, when the feed 148 is configured in a circular cross section, a function of conveying the harvesting grain stem and threshing process back to the feed 148 is unlikely to occur.

On the other hand, in the case where the gear 148 is configured to have a circular cross section, according to this configuration, the feed chamber 114 is provided from the supply port 125 by providing a spiral tooth portion (spiral blade 143) at the front end of the barrel 5a. The harvested grain stem supplied to the furnace is collected and conveyed to the rear without remaining by the spiral teeth, and clogging due to the retention of the harvested grain stem supplied from the supply port 125 to the processing chamber 114 can be prevented. .

Moreover, the partition member (2nd plate 145) which spaces back and forth the internal space of the barrel 5a is provided. Therefore, grains separated by the threshing process on the front part side of the barrel 5a by the partition member, or downstream of the threshing process direction, such as non-gall grain grain stems introduced into the internal space of the barrel 5a at the initial stage of the threshing process, etc. Is suppressed, and the granulated grains and the untapped grain stems are guided to the periphery of the barrel 5a with the rotation of the barrel 5a. It is possible to just pass the internal space and prevent the occurrence of tertiary loss caused by discharge from the downstream end in the threshing treatment direction together with the threshing grain stem.

Therefore, even when a threshing process material is supplied in large quantities, sufficient threshing process can be performed with respect to threshing process material, and the generation | occurrence | production of 3rd loss is prevented, without causing the increase of the load required for threshing process. As a result, the threshing performance and the grain recovery efficiency can be improved while avoiding damage to the barrel 5a electric system due to an increase in load, and as a result, the threshing apparatus 5 having excellent durability and processing capability can be obtained. The barrel 5a structure can be provided.

Moreover, it is comprised so that the wind fan (winnowing fan) 120 which produces a sorting wind is flown, and it flows the sorting wind from a blowhole toward the partition member (2nd plate 145).

According to this structure, the threshing process blocked by the partition member (2nd plate 145) is scattered up and down toward the periphery (peripheral of the barrel 5a) of the partition member by the sorting wind from the tuyere 120. Since it flows from the circumference | surroundings of a partition member to the downstream side of a threshing process direction with rotation of the barrel 5a, the fear that a threshing process material may accumulate in the immediately preceding part of a partition member can be avoided beforehand.

Therefore, the fall of the processing ability resulting from the deposition of threshing process material can be prevented.

In addition, it is advantageous in the following points if the rod-shaped member (the barrel frame 147) is detachably connected to the partition member (the second plate 145).

As described above, in the case of having a partition member that spaces the inner space of the barrel 5a back and forth, according to this configuration, when the rod-shaped member is connected to the partition member, the rod-shaped member is supported by the front portion and the rear portion by the support member. As a result, the intermediate portion of the rod-shaped member is supported by the partition member, so that the rod-shaped member is supported with sufficient strength.

Therefore, when the rod-shaped member is configured to be changeable in an inverted posture in which the normal posture and the front-back direction are reversed, according to this configuration, the rod-shaped member is detachably configured to the partition member so that the normal posture and the reverse posture of the rod-shaped member The direction of can be changed without any problem.

Furthermore, the dust conveying valve which has the top plate 124 which covers the upper side of the barrel 5a, and guides the threshing process conveyed to the upper part of the chamber 114 according to the rotation operation | movement of the barrel 5a to the rear ( 149 is provided in the ceiling plate 124, which is advantageous in the following points.

As described above, when the feed 148 is configured in a circular cross section, a function of conveying the harvesting grain stem and threshing process back to the feed 148 is unlikely to occur.

As a result, in the case where the gear 148 is configured to have a circular cross section, according to this configuration, the threshing treatment product is provided with the dust transfer valve 149 in the ceiling plate 124 covering the upper side of the barrel 5a. By being guided rearward by the dust transfer valve 149 without staying in), the threshing process can be prevented from clogging due to staying in the air supply chamber 114.

In addition, it is advantageous in the following points if the dust conveyance valve 149 is comprised so that it may have length over the left-right side edge part of the ceiling plate 124. FIG.

As described above, when the dust conveying valve 149 is provided in the ceiling plate 124 covering the upper side of the barrel 5a, according to this configuration, the dust conveying valve 149 is provided at the left and right side edges of the ceiling plate 124. By having the length over the part and by configuring the dust conveying valve 149 long enough, the threshing process can be guided to the rear by the dust conveying valve 149 without remaining in the feeding chamber 114 further. .

In addition, it is advantageous in the following point if the top plate 124 is comprised so that the rotational trace K which the front-end | tip of the swift tooth 148 draws in accordance with rotation of the barrel 5a may be curved.

As described above, when the dust conveying valve 149 is provided in the ceiling plate 124 covering the upper side of the barrel 5a, according to this configuration, the ceiling plate 124 is provided with the jet 148 according to the rotation of the barrel 5a. By forming the tip of the curve so as to be curved along the rotational trajectory K, the threshing workpiece is smoothly guided along the inner surface of the top plate 124, and the threshing workpiece is guided by the dust transfer valve 149. It is guided backwards smoothly.

Moreover, the water net 117 is provided below the barrel 5a, and the mesh of the water net 117 is comprised in the rectangular shape long in the rotation direction of the barrel 5a.

In the barrel 114, there are many threshing processed objects which rotate with the barrel 5a in accordance with the rotation of the barrel 5a. Thereby, according to this structure, the threshing process material which rotates with the barrel 5a by constructing the mesh of the water net 117 located below the barrel 5a in a rectangular shape long in the rotation direction of the barrel 5a. It becomes a state which follows the direction of a movement and the direction of the mesh of the water net 117, and it becomes easy to filter out the grain of threshing process from the mesh of the water net 117.
