Description
The application is a divisional application of an invention patent application with the invention name of "combine harvester", the application date of 2006, 9 and 11 and the application number of 201410836138.5.
Technical Field
The present invention relates to a combine harvester including a harvesting unit provided with a pusher-type harvesting device, a horizontal feeding screw conveyor, and a raking drum at a front end of a feeder connected to a front portion of a threshing device.
Background
As a reaping section driving structure in the above-described combine harvester, for example, a structure disclosed in japanese patent laid-open No. 2005-211010 is known. That is, power output from an intermediate shaft of a cross frame at the back of a harvesting part is transmitted to a harvesting knife drive box provided in the vicinity of a lateral side surface of a harvesting device via a transmission belt, the harvesting knife drive box and the harvesting device are coupled to each other, and a screw conveyor and a raking reel are driven by the power output from the intermediate shaft.
In the above-described conventional configuration, since the belt transmission mechanism for linking the intermediate shaft and the harvesting knife drive case is disposed laterally outside the harvesting unit, a large number of parts are required in the harvesting device drive system, which leads to an increase in cost. Further, since the friction transmission is performed via the transmission belt, there is a possibility that transmission slip due to wear or elongation of the transmission belt occurs, cutting performance of the harvesting device is lowered, and the transmission belt must be sufficiently maintained.
Disclosure of Invention
The present invention has been made in view of the above-described problems, and an object of the present invention is to simplify a drive system of a harvesting device and to reliably drive the harvesting device without requiring special maintenance work.
A first aspect of the present invention is a combine harvester including:
a threshing device,
A feeder connected to the front part of the threshing device,
A harvesting device arranged at the front end of the feeder,
A screw conveyor for transverse feeding arranged at the front end of the feeder,
A raking drum arranged at the front end of the feeder,
A feeder driving shaft transversely mounted on the base end of the feeder,
And an intermediate shaft with a cross frame at the front of the feeder,
wherein power is transmitted from the feeder drive shaft to the intermediate shaft, and further, the power branch from the intermediate shaft is transmitted to the harvesting device, the screw conveyor and the raking reel,
the intermediate shaft is provided with a rotation conversion mechanism that converts rotation of the intermediate shaft about a lateral axis into reciprocating rotation about a front-rear direction,
the harvesting machine is provided with a transmission shaft for transmitting the reciprocating rotation of the rotation conversion mechanism, the transmission shaft extends towards the front, and the front end part of the transmission shaft is linked with a harvesting device.
According to the above aspect, the swing arm is attached to the front end portion of the transmission shaft that is reciprocally rotated about the axial center in the front-rear direction, and the reciprocally swinging swing arm is linked to the harvesting knife of the harvesting device, whereby the harvesting knife can be reciprocally driven by a predetermined stroke in conjunction with the rotation of the intermediate shaft. In this case, the transmission system for transmitting power from the intermediate shaft to the harvesting device does not include a friction transmission portion, and therefore, the harvesting device can be driven without slippage.
Therefore, compared with the case of belt drive, the drive system for driving the harvesting device from the intermediate shaft can be simplified, the cost of the drive structure can be reduced, and reliable harvesting device driving can be performed without special maintenance.
A second characteristic aspect of the present invention is that the intermediate shaft is linked flexibly (wound) to the screw drive shaft, and power branched from the screw drive shaft is transmitted to the raking reel.
For example, if the power split from the intermediate shaft is transmitted to the raking reel, three power split portions for driving the harvesting device, the screw conveyor, and the raking reel are provided on the intermediate shaft so as to protrude outward in the lateral direction of the harvesting unit. Thus, the cantilever projection length of the intermediate shaft becomes long, and a large bending load is likely to be applied, so that the shaft diameter of the intermediate shaft needs to be increased. On the other hand, according to the above-described aspect, only two power branching points for driving the harvesting device and driving the screw conveyor need be provided on the intermediate shaft, and it is not necessary to particularly lengthen the cantilever projection length of the intermediate shaft. Therefore, the bending load applied to the intermediate shaft is reduced, and the diameter of the intermediate shaft may be small enough to transmit the necessary torque.
A third characteristic of the present invention is that a belt transmission mechanism is provided in a transmission system for transmitting power to the raking reel, and the belt transmission mechanism is provided with a transmission pulley for performing flexible transmission at different transmission ratios, and the speed change is performed by changing the transmission belt to the transmission pulley.
According to the above-mentioned scheme, the speed change structure of the raking reel can be configured at low cost.
A fourth characteristic aspect of the present invention is that the raking reel includes a bearing member and a support member;
the bearing member has a bearing recess opening radially outward, and a shaft support portion disposed on a tine mounting shaft of a reel frame is positioned and supported on the reel frame via an engagement mechanism and fixed to the reel frame by one bolt;
the bearing member is secured in engagement via the engagement mechanism to prevent disengagement of the tine mounting shaft which is captured in the bearing recess.
According to the above aspect, when the spool mounting shaft is mounted to the spool frame, one bolt is used for each of the left and right shaft support sections. For example, in the case of a pentagonal rake reel, only ten bolts are used when five reel mounting shafts are attached to the reel frame. Therefore, as compared with the conventional art in which two bolts are used for one shaft support portion, only half the number of bolts and the number of man-hours for operation can be used. In addition, if the pivot support portion between the auxiliary reel frame and the free end of the rotation restricting arm is also configured to have the same pivot support structure, a total of twenty bolts may be used in the case of a pentagonal rake reel.
Therefore, the tine mounting shaft integrally equipped with the rotation restricting arm can be easily attached to and detached from the reel frame with a small number of bolt operation man-hours, and the number of parts and the weight can be reduced.
A fifth characteristic aspect of the present invention is that the screw conveyor includes: a spiral conveyor roller, a fixed fulcrum shaft, a rotating fulcrum shaft, a supporting bracket, an eccentric fulcrum shaft and a raking body, wherein the two end parts of the spiral conveyor roller are fixedly provided with cover plates; a pair of left and right side plates provided at both left and right end portions of the conveying deck are provided so as to straddle the screw conveyor drum via the fixed support shaft and the rotary support shaft, and are rotatably supported; the fixed fulcrum is connected and fixed on one side plate and can penetrate through the center of one cover plate in a rotatable mode; the rotating support shaft is rotatably supported on the other side plate in a penetrating manner and is fixedly connected to the center of the other cover plate; the eccentric support shaft is connected and supported on the inner end of the roller of the fixed support shaft through a support bracket; the raking body is mounted on the screw conveyor roller in a penetrating way from the outer periphery, the base end part of the raking body is pivotally supported on the eccentric fulcrum shaft, and the raking body performs protrusion and retreat actions from the screw conveyor roller by the rotation of the screw conveyor roller; further, an assembly hole is formed in one of the cover plates of the auger roller. The assembling hole has a shape through which the eccentric fulcrum shaft and the support bracket can be inserted.
According to the above aspect, first, the conveying table and the left and right side plates are fixed to the harvesting section frame by welding or the like, the frame of the harvesting section is assembled, and the screw conveyor is assembled across the left and right side plates. At this time, the auger drum from which the fixed pivot shaft and the rotating pivot shaft are removed is inserted between the left and right side plates, and then the rotating pivot shaft bolt inserted through the other side plate from the outside is coupled to the other cover plate of the auger drum.
The end of the eccentric support shaft is connected to the fixed support shaft in a cantilever manner through the support bracket, and then the eccentric support shaft and the support bracket are inserted into the screw conveyor drum through an assembly hole formed in one side plate and an assembly hole formed in one cover plate of the screw conveyor drum.
The insertion end of the eccentric support shaft is connected to the free end of the support arm rotatably attached to the inner end of the rotary support shaft, so that the eccentric support shaft can be fixedly disposed at a predetermined position eccentric from the rotary axis of the drum in a state of being supported at both ends. Then, the process is continued. The inner end of the raking body penetrating the periphery of the screw conveyor roller is rotatably connected to the eccentric fulcrum shaft. The operation of connecting the eccentric support shaft to the support bracket and the operation of pivotally supporting and connecting the rake body to the eccentric support shaft are performed from an assembly hole openably and closably formed in the outer periphery of the screw conveyor drum.
Therefore, the screw conveyor can be pivotally supported and mounted across the space between the left and right side plates while the conveying table surface and the left and right side plates of the harvesting section are integrated by welding or the like. Therefore, compared with the conventional method in which the single side plate is mounted at the rear to support the screw conveyor between the left and right side plates, the number of assembly steps can be reduced, and the variation in the side plate mounting strength related to the rigidity of the harvesting portion can be reduced, thereby effectively stabilizing the quality.
A sixth characteristic aspect of the present invention is that the harvesting apparatus is a pusher-type harvesting apparatus in which a pair of left and right movable knives are reciprocally driven in opposite directions above a fixed knife;
the harvesting device has a hood; the cover extends from one of the pair of right and left movable blades to above the end of the other, and covers above the space between the ends of the pair of right and left movable blades.
That is, even if the space between the end portions of the movable blade is opened, the space above the end portions can be covered by the cover, and thus, rice straw or soil is less likely to enter the space between the end portions. Even if rice straw chips or soil intrudes or flies below the cover to be carried or hooked on the fixed knife or the cutter support body, the rice straw chips or soil comes into contact with the cover which extends from one movable knife and reciprocates together with the movable knife, and is easily scraped off by the cover to fall.
Therefore, according to the first aspect of the present invention, even when the movable blade is opened and closed between the end portions, the covering and scraping action by the cover can easily prevent the grass clippings, soil, and the like from being accumulated or accumulated between the end portions, and the cutting failure or the driving failure due to the grass clippings or soil is less likely to occur, and the harvesting operation can be efficiently performed.

The power input to the transmission case 42 is shifted in two stages, high and low, by the gear type sub-transmission mechanism 43, and thereafter branched to the left and right crawler belt traveling devices 1 via the pair of left and right side clutches 44.
The side clutch 44 is coupled to a lever 45 provided at the front of the driver 5, and when the lever 45 is positioned at a left-right neutral position, both the left and right side clutches 44 are "engaged" to travel straight, and when the lever 45 is operated in the left or right direction, the lever 44 is "disengaged" by the side clutch 44 on the operation side, and only the crawler travel device 1 on one side is driven, and the travel machine body 2 is turned in the operation direction of the lever 45.

This pivot support coupling portion has the same pivot support structure as that for rotatably supporting the tine mounting shaft 33 on the top of the drum frame 26.
That is, the arm portion 35b constituting the auxiliary drum frame 35 is also formed of a sheet metal material which is formed by folding out the side edge 35ba in the drum rotation direction and press-forming it into a cross section of a shape like a letter \12467andhas a recess 102 formed in its distal end portion so as to be opened outward in the radial direction so as to be able to be fitted into the pivot support shaft 101. On both sides of the recess 102, a pair of receiving pieces 35d are oppositely provided with a space through which the pivot shaft 101 can pass, and the pair of receiving pieces 35d are formed by bending distal end portions of the folded side edges 26ba of the arm portion 35b inward.
A bearing member 103 for rotatably supporting the pivot shaft 101 is attached to the inner side of the distal end of the arm portion 32 b. The bearing member 103 is made of a hard resin material having excellent sliding properties, and is formed in a substantially triangular shape that enters between the opposed folded side edges 26ba of the arm portion 35 b. A bearing recess 104 is formed on the outer end surface of the bearing member 103 so as to open radially outward, and the bearing recess 104 has a width and a depth corresponding to the outer diameter of the pivot support shaft 101, and the pivot support shaft 101 is inserted and supported therein. A pair of engaging projections 105 are provided on the outer end surface of the bearing member 103 so as to project on both sides of the bearing recess 104, and the engaging projections 105 are supported by engaging holes 106 formed in the receiving pieces 35d so as to penetrate from the inside.
A plate-like support member 107 is provided between the outer end surface of the bearing member 103 and the bearing piece 35d, and the plate-like support member 107 blocks the opening of the bearing recess 104 to prevent the pivot support shaft 101 from coming off the bearing recess 104. The support member 107 is formed with a support hole 108 through which the engagement projection 105 of the bearing member 103 is inserted, and by coupling and fixing the bearing member 103 to the arm portion 35b, the support member 107 supported by the bearing member 103 via the engagement projection 105 is fixed at a predetermined position.
One mounting hole 109 penetrating in the left-right direction is formed on the bottom side of the bearing recess 104 of the bearing member 103, and the bearing member 103 can be positioned and fixed at a predetermined position by screwing a bolt 110 inserted through the mounting hole 109 from the inside of the body to the arm portion 35 b. An annular projection 101a that engages with the left and right end surfaces of the bearing member 103 is provided on the outer periphery of the pivot shaft 101, and the auxiliary spool frame 35 is positioned in the left-right direction.
Here, the pivot support shaft 101 fixedly provided at the free end of the rotation restricting arm 91 has the same diameter as the tine mounting shaft 33, and the pivot support coupling portion thereof and the shaft support structure for rotatably supporting the tine mounting shaft 33 on the top of the barrel frame 26 are of the same specification, so that the bearing members 93 and 103, the support members 97 and 107, and the bolts 100 and 110 are commonly used, respectively.
In assembling the tine mounting shaft 33, first, the tine mounting shaft 33 is engaged in the recess 92 of the spool frame 32, and then the support member 97 is inserted between the receiving piece 32d and the tine mounting shaft 33 from the side. Then, the bearing member 93 is attached from the spool center side, the engagement projection 95 is inserted through the support hole 98 of the support member 97 into the engagement hole 96 of the receiving piece 32d, and then the bearing member 93 is fixed by the bolt 100. The pivot support shafts 101 of the rotation restricting arms 91 are also assembled to the auxiliary spool frame 35 in the same order. In the event that the tine mounting shaft 33 is to be disassembled for disassembly for repair or replacement, the reverse sequence is followed.
As shown in fig. 14 and 15, the tines 34 are formed in a pair by bending a spring wire downward in a U-shape, and are inserted from above into mounting holes 43 formed in the tine mounting shaft 33 so as to penetrate vertically. As shown in fig. 21, the upper cross portion 34a of the tine 34 is bent into a shape wound around the tine mounting shaft 33 when viewed from the lateral side, and the upper cross portion 34a is strongly pressed against the tine mounting shaft 33 to be elastically spread and deformed and to be externally fitted and fixed. The fork 34 can be detached by strongly pulling the fork 34 upward while pushing the upper cross bar portion 34a open.
According to the above configuration, when the spool mounting shaft is mounted to the spool frame, one bolt is used for each of the left and right shaft support portions. For example, in the case of a pentagonal rake reel, only ten bolts are used when five reel mounting shafts are mounted to the reel frame, and only half the number of bolts and the number of man-hours for operation are required as compared with the conventional technique in which two bolts are used for one shaft support portion. Further, if the pivot support portions between the auxiliary reel frame and the free ends of the rotation restricting arms are configured to have the same pivot support structure, twenty bolts may be used as a whole in the case of pentagonal raking the reel.
Therefore, the tine mounting shaft integrally equipped with the rotation restricting arm can be easily attached to and detached from the reel frame with a small number of bolt operation man-hours, and reduction in the number of parts and weight can be achieved.
In addition, since the bolt is mounted to the drum frame from the side, the bolt is located inside the rake drum profile. As a result, the straw planted is not easily hooked, and the threshing accompanying raking can be effectively prevented.
As described above, in the auxiliary drum frame, the pivot support coupling portion of the rotation restricting arm positions and supports the bearing member having the bearing recess opening radially outward via the engagement mechanism, and is fixed to the drum frame by one bolt, and the support member that prevents the rotation restricting arm engaged in the bearing recess from being disengaged from the opening is engaged and fixed via the engagement mechanism. Therefore, when the one-tine mounting shaft is pivotally supported and mounted across the drum frame and the auxiliary drum frame, only four bolts are required, and for example, in the case of a pentagonal rake drum, the five-tine mounting shaft can be mounted with twenty bolts, which is half the number of the conventional art, thereby promoting the above-described effect of the first invention.
Since the bearing member and the support member provided in the shaft support portion of the tine mounting shaft and the bearing member and the support member provided in the pivot support coupling portion of the rotation restricting arm are respectively configured to have the same specification, the parts of the shaft support portion of the tine mounting shaft and the pivot support coupling portion of the rotation restricting arm are promoted to be used in common, which is more advantageous for cost reduction.

As shown in fig. 24, the rotary support shaft 114 protruding from the right end of the auger drum 17 is rotatably supported via a bearing 116 by a bearing bracket 115 attached to the right side plate 78, and is rotatably supported by the support hole 26a of the intermediate support plate 113. As shown in fig. 27, an assembly hole 78a having a diameter formed so as to be able to pass through the coupling flange 114a and the bearing bracket 115 is formed in the side plate 78, a rectangular cover plate 117 is bolted from the outside to the side plate 78 so as to close the assembly hole 78a, and the bearing bracket 115 is bolted to the cover plate 117. Inside the side plates 78, a winding prevention plate 118 of a flanged disk shape that enters a recessed space formed at the right end of the auger drum 17 is fastened and fixed to the cover plate 117 by a common fastening bolt.
An input sprocket 119 is coupled to an outer end of the rotation support shaft 114 to receive a rotational driving force. An output sprocket 120 for transmitting power to the raking drum 18 is integrally formed with the input sprocket 119.
As shown in fig. 25, a fixed support shaft 122 is fixedly coupled to the left side plate 77 concentrically with the screw axis x via a coupling flange 122a, and the fixed support shaft 122 is rotatably supported through a bearing bracket 123 via a bearing 124, and the bearing bracket 123 is attached to the left side cover plate 111 of the screw drum 17. As shown in fig. 26, an assembly hole 77a having a diameter formed so as to be able to be inserted through the coupling flange 122a and the bearing bracket 123 is formed in the side plate 77, a rectangular cover plate 125 is bolted to the side plate 77 from the outside so as to close the assembly hole 77a, and the bearing bracket 123 is bolted to the cover plate 125. Inside the side plate 77, a winding prevention plate 126 of a flanged disc shape that enters a recessed space formed at the left end of the auger drum 17 and the cover plate 125 are bolted together by co-fastening.
A support bracket 127 is fixed to an inner end portion of the fixed support shaft 122 by a key connection, and a support bracket 128 is loosely fitted to an inner end side of the rotary support shaft 114 via a bearing 129 so as to be rotatable about the screw axial center x. The eccentric support shaft 130 is mounted parallel to the screw axis x across the distal end portions of the left and right support brackets 127, 42. The support brackets 127, 42 are fixed in a predetermined posture facing downward and forward, and as shown in fig. 22, the axial center y of the eccentric support shaft 130 connecting the support brackets between the two support brackets 127, 42 is set at a position offset downward and forward from the screw axial center x.
Nine mounting bosses 131 are loosely fitted to the eccentric support shaft 130 in accordance with the mounting positions of the rake fingers 22 and the auxiliary rake fingers 23, and the inner ends of the rake body 22 and the auxiliary rake body 23 are inserted into and screwed to the respective mounting bosses 131. The rake finger 22 and the auxiliary rake finger 23 rotatably mounted on the eccentric support shaft 130 via the mounting shaft bosses 131 are supported by penetrating a resin slide bush 132 mounted at a predetermined position on the outer periphery of the screw conveyor 17. An installation hole 20a is formed in an appropriate left and right portion of the outer periphery of the auger roller 17, the installation hole 20a is closed by a detachable cover 133, and a slide bush 132 is attached to the cover 133.
The auger 17 is configured as described above, and when the rotating support shaft 114 is rotationally driven to rotate the auger drum 17 forward, the rake fingers 22 and the auxiliary rake fingers 23 rotate around the axial center y of the eccentric support shaft 130, and at this time, the distance between the eccentric support shaft 44 and the slide bushes 132 changes according to the rotational phase, and the rake fingers 22 and the auxiliary rake fingers 23 protrude and retract from the auger drum 17 accordingly, between the left and right side plates 77 and 12.
In this case, the amount of protrusion of the rake fingers is maximized on the forward extension line connecting the axis x of the screw conveyor and the axis y of the eccentric support shaft 130, and the amount of protrusion of the rake fingers is minimized on the opposite phase. Therefore, the crop transversely fed by the screw blade 18 is raked rearward by the largely protruding raking fingers 22 and the auxiliary raking fingers 23, is conveyed rearward along the conveying surface 14 so as to be submerged below the screw conveyor drum 17, and is fed into the front inlet 221 of the feeder 6.
Next, a procedure for assembling the screw conveyor 17 between the left and right side plates 77, 12 will be described.
In assembling, the connecting flange 114a is keyed to the rotary support shaft 114. On the other hand, a support bracket 123 is mounted on the fixed support shaft 122 via a bearing 124, and a support bracket 127 is keyed. The left end of the eccentric support shaft 130 to which the mounting boss 131 is fitted is coupled and fixed to the free end of the support bracket 127, and the right end of the eccentric support shaft 130 is coupled to the support bracket 128 to which the bearing 129 is mounted.
The auger roller 17 is inserted between the left and right side plates 77, 12 in a state where the winding prevention plates 118, 39 are temporarily assembled and inserted into the recessed spaces at the left and right end portions of the auger roller 17.
Next, the rotation support shaft 114 assembled in advance as described above is inserted into the auger drum 17 through the assembly hole 78a of the side plate 78, and is inserted through the support holes 26a of the right-side cover plate 112 and the intermediate support plate 113. Then, a tool such as a socket wrench is inserted through the assembly hole 78a, and the coupling flange 114a is bolted to the cover plate 112. Then, a bearing bracket 115 to which a cover plate 117 is attached in advance is fitted to the rotation support shaft 114 via a bearing 116, and the cover plate 117 is bolted to the side plate 78 from the outside to close the assembly hole 78a. In addition, the winding prevention plate 118 is co-fastened to the side plate 78 when the cover plate 117 is bolted to the side plate 78. Thereafter, the input sprocket 119 and the output sprocket 120 are attached to the protruding portions of the rotation support shafts 114.
Next, the fixed support shaft 122, to which the eccentric support shaft 130 and the support brackets 127 and 42 and the like have been previously assembled as described above, is inserted into the auger drum 17 through the assembly hole 77a of the left side plate 77. At this time, since the assembly hole 111a having a shape through which the support brackets 127 and 42 can be inserted is formed in the left cover plate 111, the support brackets 127 and 42 and the eccentric fulcrum shaft 130 are inserted between the cover plate 111 and the intermediate support plate 113 through the assembly hole 111 a.
Next, a tool such as a socket wrench is inserted through the assembly hole 77a to bolt the bearing bracket 123 to the cover plate 111, and then the cover plate 125 is attached to the connecting flange 122a, and the cover plate 125 is bolted to the side plate 77 from the outside, whereby the fixing support shaft 122 is fixed to the side plate 77 and the assembly hole 78a is closed. In addition, the winding prevention plate 126 is co-fastened to the side plate 77 when the cover plate 125 is bolted to the side plate 77.
A support bracket 128 connected to the right end of the eccentric support shaft 130 is loosely fitted to the inner end of the rotary support shaft 114 via a bearing 129. This assembly operation is performed through the assembly hole 20a on the right side of the auger roller 17.
Next, a tool is inserted through each of the open assembly holes 20a, and the inner ends of the raking fingers 22 and the auxiliary raking fingers 23 are inserted and coupled to the mounting boss 131 externally fitted to the eccentric support shaft 130. Thereafter, the respective caps 133 are coupled to the auger roller 17 in a state where the rake fingers 22 and the auxiliary rake fingers 23 are inserted into the slide bush 132, and the respective assembly holes 20a are closed.
Through the above operations, the assembly of the auger roller 17 is completed.
(details of harvesting apparatus)
Next, an example of the detailed configuration of the harvesting device 12 will be described with reference to the drawings. However, the detailed structure of the harvesting unit 12 is not limited to the following manner.
As shown in fig. 29, the pusher-type harvesting apparatus 12 is configured by providing one fixed blade 202 and movable blades 206, wherein the fixed blade 202 is supported by the base portions of a plurality of grass-dividing frames 11 arranged at predetermined intervals in the lateral direction of the machine body, and the movable blades 206 are provided above the left and right portions of the fixed blade 202.
The pusher-type harvesting apparatus 12 is provided in a pre-harvesting treatment section of a combine harvester, and harvests planted straw introduced between straw-separating frames from the straw-separating members 200 provided at the end sides of the straw-separating frames 11, and has a detailed structure in which the combine harvester harvests planted straw such as rice and wheat, threshes the harvested straw, and recovers the threshed grain into a threshing box for storage or a bagging storage for bagging.
As shown in fig. 29, 30, 31, and the like, the fixed blade 202 includes one fixed blade table 203 and a plurality of fixed blades 205, the one fixed blade table 203 is attached to a harvesting blade support 201 (see fig. 36) connected to a lower side of a base portion of each grass frame 11, and the plurality of fixed blades 205 are arranged along a lateral direction of the machine body on an upper surface side of a front edge portion of the fixed blade table 203 and are fixedly attached by rivets 204.
As shown in fig. 29, 30, 31, and the like, each movable blade 206 includes a plurality of movable blades 207 arranged in the lateral direction of the machine body at an arrangement pitch having the same length as the arrangement pitch of the fixed blades 205 of the fixed blade 202, and one blade bar 23 fixedly attached to the upper surface side of each movable blade 207 by a rivet 208 to connect the plurality of movable blades 207.
As shown in fig. 29, 32, and 33, each of the harvesting knife drive mechanisms 221 includes a swing link 230, a link 231, and a drive rotating body 223; the swing link 230 includes an operation roller 222 at one end, and the operation roller 222 is formed by a bearing inserted between a pair of left and right operation plates 211 of the movable blade operation body 210 of the movable blade 206 to be driven; one end of the link 231 is relatively rotatably connected to the other end of the swing link 230; the other end of the link 231 is connected to the driving rotator 223 at the peripheral edge thereof so as to be relatively rotatable.
The swing link 230 has an intermediate portion rotatably connected to a support shaft 232 provided in the straw conveying device (not shown), and the swing link 230 is reciprocally swung about the axis of the support shaft 232. The driving rotor 223 is rotatably supported via a rotation support shaft 224 at an end of a transmission case 226 constituting a frame of the pre-harvest treatment section.
Thus, each of the harvesting knife drive mechanisms 221 converts the rotational drive force of the drive rotating body 223 driven around the body vertical axis of the rotating support shaft 224 into linear reciprocating power via the interlinking lever 43, transmits the linear reciprocating power to the end of the swing link 230, drives the swing link 230 to swing reciprocally around the body vertical axis of the support shaft 232 at a fixed swing angle, and transmits the reciprocating power of the swing link 230 to the movable knife operating body 210 via the operating roller 222, thereby driving the movable knife 10 reciprocally.
The pair of harvesting knife drive mechanisms 221 reciprocally drive the left and right movable knives 206 in the following states in accordance with the setting of the rotational phase of the drive rotating body 223, and the like: when the left movable knife 206 slides toward the outside of the machine body, the right movable knife 206 also slides toward the outside of the machine body, and when the left movable knife 206 slides toward the inside of the machine body, the right movable knife 206 also slides toward the inside of the machine body, that is, the pair of left and right movable knives 206 slide back and forth in opposite directions.
That is, in the clipper-type harvesting apparatus 12, in a state where the pair of right and left movable blades 206 are reciprocated in opposite directions above the fixed blade 202, and in a state where the pair of right and left movable blades 206 are opened and closed above the harvesting knife support 201 provided in the grass frame 11 located at the center portion in the lateral direction of the machine body between the end portions of the pair of right and left movable blades 206, the pair of right and left movable blades 206 are reciprocated by the pair of harvesting drive mechanisms 221, so that the planted straw from the plurality of seedling dividing pieces 200 located on the left side of the harvesting portion is harvested by the fixed blade 205 located on the left side portion of the fixed blade 202 and the movable blade 207 of the left movable blade 206 relatively moved to the fixed blade 205, and the planted straw from the plurality of seedling dividing pieces 200 located on the right side of the harvesting portion is harvested by the fixed blade 205 located on the right side portion of the fixed blade 202 and the movable blade 207 of the right movable blade 206 relatively moved to the fixed blade 205.
As clearly shown in fig. 34 and 35, the cover 227 is extended from the end of one movable blade 206 of the pair of left and right movable blades 206 to above the end of the other movable blade 206, and the cover 227 has a sufficient extension length to cover the space S between the ends of the pair of left and right movable blades 206 and to cover the entire range between the ends even in a state where the ends are opened to the maximum size by the reciprocating movement of the two movable blades 206 in opposite directions.
Accordingly, the entry of chaff, mud, or the like between the end portions of the left and right movable blades 206 is prevented by the cover 227, and even if the chaff, mud, or the like intrudes or flies into between the end portions and is caught by the fixed blade 202 or the cutting blade support 201 below between the end portions, the chaff, mud, or the like comes into contact with the cover 227 reciprocating together with the movable blade 206, and is easily dropped by the scraping action of the cover 227, so that the harvesting process is performed.
As shown in fig. 30 and 31, the support mechanism 215A for supporting the outer end portion of each movable blade 206 in the lateral direction of the machine body includes: a rear slide guide 218 fixed to the fixed tool rest 203 by a connecting bolt 217; the holder 216 made of a spring plate, the rear end portion of which is fixed to the fixed tool rest 203 together with the rear slide guide 218 by the coupling bolt 217; the front slide guide 220 is coupled to the front end of the holder 216 by a rivet 219. The support mechanism 215A slidably sandwiches the sliding portion 26 of the blade 209 by the front sliding guide 220 and the rear sliding guide 218, and supports the movable blade 206 so as to slide in the transverse direction of the machine body with respect to the fixed blade 202 by the support mechanism 215A slidably sandwiching the sliding portion 26 of the blade 209 by the front sliding guide 220 and the rear sliding guide 218.
As shown in fig. 33, 34, and 35, the support mechanism 215C for supporting the inside end of the body of the movable knife 206 to which the cover 227 is coupled includes: a rear slide guide 218 fixed to the fixed tool rest 203 by a connecting bolt 217; the rear end portion of the holder 216 made of a spring plate is fixed to the fixed base 203 together with the rear slide guide 218 by the coupling bolt 217; the front slide guide 220 is coupled to the front end of the holder 216 by a rivet 219. A rear slide contact portion 229a and a front slide contact portion 229b are provided in the attachment portion 228 of the cap 227 that is connected to the movable blade 206 by the rivet 208, so as to slide on the rear slide guide 218 or the front slide guide 220 of the support mechanism 215C provided in the fixed blade 202, and the rear slide contact portion 229a is disposed between the arbor 209 of the movable blade 206 and the rear slide guide 218; the front slide contact portion 229b is disposed between the knife bar 209 of the movable knife 206 and the front slide guide 220. The attachment portion 228 of the cover 227 is made of a material different from that of the holder 209, and the rear sliding contact portion 229a and the front sliding contact portion 229b have hardness and wear resistance superior to those of the holder 209.
As shown in fig. 32, a driven plate 212 is detachably attached to the pair of left and right operation plates 211 of the movable blade operating body 210 provided in the movable blade 206 via a connecting bolt 213, thereby forming a contact surface 214 with which the operation roller 222 of the swing link 230 comes into contact. Thus, when the contact surface 214 is worn, it is possible to deal with the situation without replacing the movable knife 206 and the movable knife operating body 210 only by replacing the driven plate 212.
As described above, the mounting portion of the cover coupled to the one movable blade includes the sliding contact portion that is located between the blade holder of the one movable blade and the sliding guide of the fixed blade and slides on the sliding guide. That is, as the movable blade is driven to reciprocate, the mounting portion of the cover slides relative to the slide guide body at the slide contact portion, whereby the movable blade can be reciprocated while suppressing the play of the movable blade relative to the fixed blade.
Therefore, the movable blade can be driven quietly with less looseness, and the cover is used as the sliding contact member, which is advantageous in terms of both the structure and the economy.
The pusher-type harvesting device 12 of the present invention is not limited to a combine harvester, and is also applicable to a pusher-type harvesting device 12 equipped in various types of harvesters other than a combine harvester.
