[

As shown in Figs. 10, 12, 13 to 16 and Fig. 23, the supply and conveyance apparatus 125 is provided at the rear of the grain straw passage 127 by the left and right rak transportation apparatus 124A, 124B A base cooperating conveying mechanism 182 for conveying the scraped-off grain straw to the nipping and conveying mechanism 131 of the threshing apparatus 104 while holding the bottom side of the scraped grain straw, And an end-edge-holding mechanism 183 for carrying the end-edge-holding mechanism 183 toward the supply port 104A. The base cooperating and holding mechanism 182 and the end end holding mechanism 183 are configured such that the transmission shaft 184 functioning as the input shaft thereof is connected to the input shaft 138 of the preload 103 via the pair of bevel gears 185, So that the grain straw passing through the grain straw passing portion 127 is fed and conveyed toward the threshing device 104 while changing posture from the standing posture to the right side collapsing posture for threshing.

The supply and conveyance device 125 is configured to be capable of up and down movement using the input shaft 138 of the pre-installation part 103 located at the conveying end part 125a as a fulcrum. By this up-and-down swing, the conveying end portion 125b can be adjusted in position in the grain-straw direction with respect to the grain straw passed through the grain-straw passing portion 127. By this position adjustment, It is possible to change the feed length of the grain end to the inside of the grain weir device 104 in the grain straw to control the threshing depth to control the grain threshing depth of the grain straw by the threshing device 104.

The preloading section 103 is provided with a guide lever 186 for guiding the transport start end portion 125b of the supply and conveyance apparatus 125 to swing in the up and down direction while suppressing the swinging movement of the supply and conveyance apparatus 125 in the left- I have installed.

The support frame 190 is provided with a cutting edge sensor 195 for detecting the cutting edge position of the grain straw conveyed by the feeding and conveying device 125. The cutting edge sensor 195 is provided with a pair of sensor arms 196A and 196B. The pair of sensor arms 196A and 196B are arranged at a predetermined distance in the longitudinal direction of the grain straw on the end of the grain straw conveyed by the feed and conveyance device 125. [ The edge sensor 195 outputs the edge position of the grain straw detected by the pair of sensor arms 196A and 196B to the controller 197 configured using a microcomputer. The control device 197 is provided with an electric motor 191 of the adjusting means 187 so that the length of the end of the grain straw to be fed into the threshing device 104 becomes constant based on the output of the edge sensor 195 And a control unit 197A for controlling the threshing depth. The control means 197A detects that the sensor arm 196A located on the bottom side of the grain straw detects the end of the grain straw and the sensor arm 196B located on the end of the grain straw is positioned on the edge of the grain straw The length of the grain end of the grain straw to be supplied to the inside of the trolley unit 104 is made constant by controlling the operation of the electric motor 191 so that the state of not detecting the end side is maintained.

Although not shown, the pair of sensor arms 196A and 196B are configured so that the position of the grain straw conveyed by the feeding and conveying device 125 can be changed integrally in the grain length direction. By changing the positions of the sensor arms 196A and 196B to the base side of the grain straw by the change of the position, the grain threshing depth of the grain straw by the threshing apparatus 104 is supplied to the inside of the threshing apparatus 104 To the shallow threshing side which shortens the cutting edge length of the grain straw. Further, by changing the positions of both sensor arms 196A and 196B to the end of the grain straw, the grain threshing depth of the grain straw by the threshing apparatus 104 can be adjusted to the grain- It is possible to adjust to the deep threshing side which lengthens the end length.

As shown in Figs. 10 to 12, Figs. 15 and 16, an ear lever 198 for enabling the position changing operation of the pair of sensor arms 196A and 196B is mounted on the ear edge sensor 195 . The operation lever 198 is disposed so as to be positioned at a position near the operation unit 102 of the end-of-cut sensor 195. Thereby, the operating lever 198 can be operated while sitting on the operation section 102, and the threshing depth of the grain straw by the threshing device 104 can be adjusted.

17, 18, and 22, the center divider 121C of the preloading section 103 has a curvature of the left and right packers 172A, 172B which is within the width of the left and right of the grain straw passage 127 da and db.

By this arrangement, when the post-cut grain straw is transported toward the grain passage section 127 by the left and right rake transport devices 124A, 124B, the grain straw is prevented from moving to move beyond the center divider 121C can do. As a result, as compared with the case where the grain straw passes over the center divider 121C, the bottom side of the grain straw can be prevented from contacting the center divider 121C, whereby the conveying posture of the grain straw The alignment of the end of the grain when the grain straw is transported toward the threshing device 104 by the supply and conveyance device 125 is deteriorated due to the disturbance and the threshing residue is generated in the threshing process in the threshing device 104 It is possible to avoid a drop in the recovery rate of the curled grains that can be easily obtained.

As described above, the left and right rake conveying devices 124A and 124B are arranged such that the attitude of the rake conveying mechanisms 171A and 171B of the right and left rake conveying devices 124A and 124B in the state where the pre- The posture of the packers 172A and 172B becomes the rearwardly inclined posture so that the preloading portion 103 is positioned in the rearwardly inclined posture The center divider 121C which is in a horizontal posture or a substantially horizontal posture when it is positioned in the work area is spaced upward from the center divider 121C by the lower side in the conveying direction. This prevents the grain straw which is rake-transported toward the grain straw passing portion 127 by the right and left rak transporting devices 124A and 124B from contacting the center divider 121C in the grain straw passing portion 127 As a result, it is possible to prevent the drop of the grain recovery rate due to the disturbance of the delivery posture of the grain straw due to the contact.

Fig. 24 is a schematic plan view of the main part showing the working state of the four-part cutting, and Fig. 25 is a schematic plan view of the main part showing the working state of the three cutting. As shown in Fig. 12, Fig. 13, Fig. 24 and Fig. 25, the left and right end portions of the preload portion 103 (left and right ends on the side separated from the operation portion 102 in the preload portion 103) And the crawler 113A on the left side (the side separated from the operation unit 102) are connected to the left end 113Aa of the left crawler 113A and the left end 121Aa of the left side divider 121A, Are positioned so as to coincide with each other in the lateral direction of the vehicle body. The right side divider 121B and the right side (operation side) crawler 113B located at the right end portion of the preload portion 103 (the left and right side end portions of the operation portion side in the preload portion 103) The right end 113Ba of the left dividing member 121B slightly protrudes from the fulcrum starting end 121Ba of the right dividing member 121B to the right side of the vehicle body and the right end 113Ba of the right dividing member 121B is separated from the right crawler 113B, The right side end portion 113Ba of the vehicle body is positioned substantially coincident with the position in the lateral direction of the vehicle body.

That is, the left and right crawlers 113A and 113B are arranged in such a manner that the distance L between the ends of the left and right ends of the left and right crawlers 113A and 113B is greater than the working width W of the pre- Direction at a predetermined interval. Thereby, the distance between the wheels of the left and right crawlers 113A and 113B can be made longer, and the turning performance of the crawlers 113A and 113B is not increased by increasing the grounding length, .

The left crawler 113A is positioned such that the left end 113Aa of the left crawler 113A coincides with the left end of the left dividing end 121Aa of the left divider 121A to protrude to the left side of the vehicle body from the starting end 121Aa It is not. As a result, when the uncut crops Cx and Cy are present outside the left and right sides of the surrounding waste cuts or the base 101 where the uncooked crops Cx are present on the left side outside of the base 101, The left crawler 113A presses the uncut crop Cx located in the vicinity of the left outer side thereof or the moor crop Cx located near the left outer side thereof by the left crawler 113A, It is possible to prevent the occurrence of troubles such as elongation and the like, and it is possible to avoid lowering of the working efficiency due to the stepping or the clay.

On the other hand, the right crawler 113B is arranged so that the position of the right end portion 113Ba thereof substantially coincides with the left and right direction of the branching end portion 121Ba of the right side divider 121B, (Cb) in the working width of the preloading section (103) and the front end of the crop (Cb) in the working width of the preloading section (103) (Cb) within the working width between the cropping area (Cb) outside the working width adjacent to the working width and the crop (Cy) outside the working width neighboring the working width, the right crawler (113B) It is possible to prevent the occurrence of the problem of stepping on the uncut crop Cy, and it is possible to avoid a reduction in working efficiency due to the stepping.

In addition, the protruding length Lz of the right crawler 113B from the fulcrum starting end 121Ba of the right side divider 121B to the right side of the vehicle body is equal to the length Lz of the right side crawler 113B, If it is a length that can prevent the cropped crop Cy from being stepped on, for example, Lz = 1/3 * Sc or Lz = 1/4 * Sc etc. may be obtained from the relationship with the planting interval Sc of the crop C It is preferable that Lz < / = 1/6 * Sc. The shorter the length Lz of the protrusion, the less the clay of the uncut crop Cy near the right outside of the vehicle body by the right crawler 113B can be restrained, and the higher the working efficiency Can be suppressed. On the other hand, the longer the length Lz of the protrusion, the longer the distance between the wheels of the left and right crawlers 113A and 113B can be, and the wet performance can be improved.

That is to say, it is possible to prevent the uncut crops Cx and Cy from being trampled by the left and right crawlers 113A and 113B and clay to the uncut crops Cx and Cy, It can be configured with the full cutting specification.

The right crawler 113B is arranged so that the right end 113Ba of the right crawler 113B coincides with the left and right direction of the right and left dividers 121Ba of the right dividers 121B, It may be arranged so as to be located inside the vehicle body. The left crawler 113A may be disposed such that its left end 113Aa is located inside the vehicle body relative to the fulcrum starting end 121Aa of the left divider 121A and the left crawler 113A may be disposed on the left side of the vehicle body by the left crawler 113A It is possible to prevent the uncut crop Cx in the vicinity of the left side divider 121A from being stepped on and the left end 113Aa of the left side divider 121A But may be disposed so as to be located on the left side of the vehicle body than the minute end portion 121Aa.

As shown in Fig. 24, the three dividers 121A to 121C are arranged in such a manner that the right dividers 121B are arranged such that the branching start ends 121Ba of the right dividers 121Ba, (Cb) in the working width between the rightmost crop Cb in the working width of the crop Cb and the crop Cy other than the working width on the right side adjacent to the crop Cb or the crop- Cb of the two crops Cc and Cd located on the left and right center sides in the working width to be the operation target when the center divider 121C is aligned with respect to the crop C And the left dividers 121A pass the middle position or approximately the middle position and the left dividers 121A are positioned at the leftmost working crop Ca in the working width of the preloading portion 103, Is closer to the crop Ca in the working width than the intermediate position thereof between the crop Cx or the cut-off trail Cz of the crop So as to pass through the position.

That is, at the time of running a four-piece work, the firing start end portion 121Ba of the right side divider 121B, which is located in the lower portion in front of the operation portion 102 and has high visibility from the operation portion 102, The left dividers 121A and the center divider 121C which are separated from the operation section 102 and are low in visibility from the operation section 102 are positioned so as to pass through the right lateral side of the crop Cb located thereon, It is possible to pass an appropriate position deviating from the planting position of the crop C without observing and to avoid the fall of the crop C by the dividers 121A and 121C or the stepping on of the crop C by these dividers 121A and 121C.

This makes it possible to easily and reliably align the respective dividers 121A to 121B at appropriate positions with respect to the crop C even when the crop C is badly coated, Up of the grain straw by the up-shifting devices 122A and 122B can be efficiently performed.

Further, the center divider 121C is introduced into the range of the left up-hoisting frame 126A by passing through the middle position or approximately the middle position of the two crops Cc and Cd located on the left and right center sides in the working width The grain straw of the two crops Ca and Cc and the two grain crops Cb and Cd of the two crops Cb and Cd introduced into the range of the right uplifting frame 126B are stacked on the grain straw It is possible to place the passing portion 127 at a symmetrical position with the left and right sides therebetween so that the distance from the grain straw passing portion 127 of the left and right grain straw can be uniformly shortened.

This allows the center divider 121C to feed the two crops Cc and Cd located at the left and right center sides in the working width while introducing the two crops C of the crop C into the left and right raising frames 126A and 126B, The distance from the grain straw passing portion 127 of the grain straw introduced into either one of the right and left raising frames 126A and 126B becomes unnecessarily long and the distance between the left and right rake frames 126A and 126B becomes short, It is possible to prevent the feeding efficiency of the grain straw from being lowered by the feeding rollers 124A, 124B. Further, it is possible to prevent an unnecessary delay from occurring in the conveyance of the grain straw by either one of the right and left rak conveying devices 124A and 124B, and by the disturbance of the conveying posture of the grain straw due to this delay, It is possible to prevent the lowering of the grain recovery rate that torture is liable to occur in the threshing process in the threshing device 104 because the edge of the grain end when the grain straw is transported toward the threshing device 104 can do.

In addition, when the left dividers 121A pass near the left lateral side of the crop Ca positioned at the leftmost position in the working width, when the work is carried out to harvest the four sets of crops C, It is necessary to align the firing start portion 121Ba so as to pass through the right side lateral side of the crop Cb positioned on the rightmost side in the working width.

This makes it possible to reliably pass the respective dividers 121A to 121C to the above-mentioned proper positions for the crop C at all times during the operation of harvesting the four crops C, It is possible to improve the workability at the time of running a work for harvesting the crop (C).

As shown in Fig. 25, the three dividers 121A to 121C are arranged in such a manner that the right dividers 121B are arranged in such a manner that the right dividers 121Ba, (Cz) so as to pass above the rightmost crop (Cb) in the working width of the cropping area (103) of the right crop and the upper part of the adjacent cropping cutter station (Cz) Is positioned closer to the crop Cc on the left and right center sides than the right crop Cb between the two crops Cb and Cc positioned on the right side and the left and right central sides of the working width to be the target of operation And the left dividers 121A are arranged in such a manner that the leftmost crop Ca in the working width of the preloading section 103 and the crops other than the left working width adjacent to this crop Ca (Cx) of the crop or the cutting edge Cz of the crop.

That is, at the time of the three-piece cutting operation, the firing start end portion 121Ba of the right side divider 121B, which is located in the lower portion in front of the operation portion 102, The left dividers 121A and the center divider 121C having low visibility from the operation section 102 can be separated from the operation section 102 so as to pass through the crops C of the crop C by the dividers 121A, 121C, so that the crop C can be prevented from falling down or stepping on by the dividers 121A, 121C.

This makes it possible to easily and reliably align the right dividers 121B and the center divider 121C with respect to the crop C even when the crop C is heavy, 121B and the left and right lifting devices 122A, 122B can be efficiently performed.

The center divider 121C passes through the vicinity of the right side of the crop Cc positioned at the left and right center sides in the working width to generate two sets of crops Ca and Cc introduced into the range of the left up- And the grain straw of a set of crops Cb introduced into the range of the right uplifting frame 126B from the grain straw passage 127 positioned immediately above the center divider 121C, It is possible to make the distance between the grain straw of the left crop Ca and the grain straw passage 127 shortest.

As a result, the conveying efficiency can be improved when the three pairs of grain straws are raked toward the grain passing portions 127 by the right and left rak conveying devices 124A and 124B. Further, it is possible to prevent an unnecessary delay from occurring in the conveyance of the grain straw by either one of the right and left rak conveying devices 124A and 124B, and by the disturbance of the conveying posture of the grain straw due to this delay, It is possible to prevent the lowering of the grain recovery rate that torture is liable to occur in the threshing process in the threshing device 104 because the edge of the grain end when the grain straw is transported toward the threshing device 104 can do.

In addition, when the left side divider 121A is located at the middle or substantially intermediate position between the crop Ca positioned at the leftmost position in the working width and the crop Cx other than the working width at the left side or the cutting edge Cz of the crop, The left dividers 121A having the lowest visibility from the operation unit 102 are moved from the planting position of the crop C as the operation target to the operation And can be located at the most spaced position within the range.

This makes it possible to cause the left dividers 121A having the lowest visibility from the operation unit 102 to act favorably on the crops C to be actuated when the three crops C are being harvested, It is possible to more reliably prevent the left side divider 121A from being positioned at the planting position of the crop C to be operated.

Incidentally, the concrete arrangement of the three dividers 121A to 121C for satisfying the positional relationship between the above-described three dividers 121A to 121C and the crop C is such that the left and right spacing of the three dividers 121A to 121C The arrangement in which Sa = Sb = 1.75 * Sc, the arrangement in which Sa = Sb = 1.75 * Sc, or Sa > Sb in the relationship between Sa and Sb and the planting interval Sc of the crop C An arrangement in which Sa = 1.75 * Sc and Sb = 1.75 * Sc, arrangement in which Sa < Sb and Sa = 1.75 * Sc and Sb = 1.75 * Sc, and the like can be considered. The distance La between the left divider 121A and the leftmost crop Ca in the working width positioned on the right side of the work is equal to the distance La between the right divider 121A Of the working width and the distance Lb between the rightmost crop Cb in the working width located on the left side thereof.

As shown in Figs. 12, 13 and 17, the right and left dividers 121A and 121B are arranged such that the posture of the pulleys 151A and 151B is inclined at an inner side of the vehicle body in the lateral direction of the vehicle body Posture. This makes it easier for the crops Ca and Cb located at the left and right ends of the working width of the preloading portion 103 to approach toward the right and left center in the working width.

As shown in Figs. 10 to 13 and Figs. 15 to 18, on the front end portion in the left-right direction of the preload 103, there are a left minute section 199A, a right minute section 199B, And a central minute interval 199C located at the left and right center of minute minutes 199A and right minute minutes 199B.

As shown in Figs. 10, 12, 13, and 15, the left temporal interval 199A is defined by an acting posture tilted so as to protrude outward to the left side of the base 101, And is configured to be able to change its posture by rocking motion in a storage posture standing upright to retreat to the gas side. By changing the left ventricle 199A to the working posture, it is possible to prevent the unfinished crop Cx existing outside the left side of the base 101 from being applied to the inside of the vehicle body.

Fig. 26 is a perspective view of the main part showing the installation structure on the side of the minute end portion of the left temporal interval 199A. As shown in Figs. 10, 12, 13, 15, and 26, the left temporal section 199A has its first temporal end 199a connected to the first connection portion 200 So as to be swingable. An extending end portion 201a of the connection link 201 extending from the second end portion is pivotally connected to the support member 136 of the preload portion 103 through the second connection portion 202. [

The first connection part 200 is provided with an L-shaped bracket 203 welded to the left side support 151A and a bracket 203 capable of pivoting the bracket 203 on the left side of the minute seconds 199A The connecting pin 204 is configured so that the connecting pin 204 is close to the left side of the left jetting hole 151A.

The second connection portion 202 includes a bracket 205 welded to the support member 136, a connection pin 206 for pivotally connecting the extension end 201a of the connection terminal 201 to the bracket 205, And a retention mechanism 207 for maintaining the posture of the left temporal interval 199A. A space existing immediately behind the left end portion of the left side lift frame 126A is effectively used so as to be located on the left and right center sides of the preload portion 103 rather than the first connection portion 200, And is arranged so as to be located at the left and right center sides of the base 101 than the left end 113Aa of the crawler 113A.

The retaining mechanism 207 is formed by forming an arc-shaped elongated hole 205a around the connecting pin 206 in the bracket 205 and inserting the bolt 208 through the elongated hole 205a, A compression spring 209 is externally inserted into the end of the insertion end of the bolt 208 and a pair of nuts 210 are screwed together so that the extension ends The posture of the left minute segment 199A is maintained while allowing the pivotal motion of the left minute segment 199A along the elongated hole 205a and the storage posture to be performed, .

With the above arrangement, even if the second connecting portion 202 is configured as a large size including the holding mechanism 207, the left end 199A of the preload portion 103 can be moved to the left end It is possible to prevent the second connecting portion 202 from being deformed by contact with another portion such as a slab during the operation of harvesting the crop C of the buckwheat. This is particularly effective in preventing the deformation of the second connecting portion 202 due to contact with the concrete block in a package in which the block is formed low by a concrete block or the like.

The pivot axis P of the left minute segment 199A passing through the center of the connection pin 204 of the first connection part 200 and the connection pin 206 of the second connection part 202 is connected to the pre- When the pivot axis P of the left minute segment 199A is set to the posture along the front-rear direction of the preload portion 103 by the inclined posture located at the left and right center sides of the preload portion 103 by the rear side of the preload portion 103 It is possible to reduce the operating angle at the time of pivotal operation of the left temporal interval 199A over the storage posture and the working posture and to improve the operability of the left temporal interval 199A.

FIG. 27 is a plan view of a main part showing a state in which the left minute segment 199A is changed to a storage posture. As shown in Figs. 13 and 27, the left temporal section 199A has a storage posture in which the minute end portion 199b is located closer to the left and right central portions of the base 101 than the left end portion of the preload portion 103 And the position in the transverse direction of the vehicle body substantially coincides with the longitudinal end portion 199b of the preload portion 103 and the left end portion of the preload portion 103. [

As a result, the left temporal interval 199A is set such that the minute end portion 199b of the left temporal interval 199A is located on the left and right center sides of the base 101 than the left side end portion 113Aa of the left crawler 113A , The position in the lateral direction of the vehicle body substantially coincides with the minute end portion 199b and the left end portion 113Aa of the left crawler 113A.

That is, by shifting the left minute segment 199A to the storage posture, the minute end portion 199b of the left minute segment 199A is moved to the left end portion of the preload portion 103 and the left end portion 113Aa of the left crawler 113A, The entire left temporal section 199A can be positioned at the left and right center sides of the base 101 so that the whole of the left temporal section 199A can be positioned at the left and right outside of the left end portion 113Aa of the left crawler 113A 131 in the vehicle body in the lateral direction of the vehicle body. As a result, as compared with the case where the minute end portion 199b of the left temporal section 199A is located outside the left side of the vehicle body than the left side outer end portion of the nipping and conveying mechanism 131, The overall width of the combine in the changed state can be made small, and the storage ability of the barn can be improved.

The left minute segment 199A is configured such that the minute end portion 199b is located above the grain conveying route 188 of the feeding and conveying device 125 above the vehicle body in its storing posture. This allows the grain straw to be fed to the threshing device 104 (not shown) without being brought into contact with the minute end portion 199b of the left minute bar 199A by the feed and conveyor device 125 even when the left minute bar 199A is changed to the storing posture As shown in Fig.

That is, even if the work travel is performed in the state in which the left minute segment 199A is changed to the storage posture, the grain straw conveyed by the feeding and conveying device 125 comes into contact with the minute end portion 199b of the left minute segment 199A You can avoid concerns. As a result, the conveying posture of the grain straw is disturbed due to the contact, so that the alignment of the grain ends of the grain straw is deteriorated and the grain residual recovery is likely to occur in the threshing process in the threshing device 104. [ Can be avoided in advance.

Further, in the state in which the left minute span 199A is changed to the storage posture, the entire left minute span 199A is greater than the left outer end of the gripper conveying mechanism 131 of the threshing device 104, The work can be run in a state in which the vehicle body is closer to the block, so that the position of the left divider 121A with respect to the crop C of the head can be easily aligned. As a result, it is possible to improve the workability in the murage.

Further, with respect to the crop C of short grain straw having a crop straw length of about 65 to 75 cm and less likely to be wrapped, the left minute segment 199A is changed to a storage posture so that the left minute segment 199A does not act on the end of the grain It is possible to avoid the risk of the grains falling off from the grain straw due to the action of the left minute segment 199A on the grain straw of the crop C in advance, and as a result, the grain recovery efficiency can be improved. This is particularly effective when harvesting Indica rice or the like which is easy to flake.

As shown in Figs. 10 to 13 and Figs. 15 to 17, the central minute span 199C is formed in the front end portion of the preload portion 103 in the substantially right and left middle portions of the left and right shunting devices 122A, And is installed upright from the central minute hole 151C to the connecting member 167 so as to be positioned at the position.

By this rake action of the respective claws 159A and 159B in the guide areas Aa1 and Ab1 of the right and left uplifting devices 122A and 122B the other lifting devices 122A and 122B The grain straw of the crop C which crosses when viewed from the front of the vehicle body on the front side of the vehicle body of the roll-up regions Aa1 and Ab1 of the respective roll-up devices 122A and 122B, Can be divided right and left toward the skewed areas Aa1 and Ab1 of the corresponding skewers 122A and 122B by the minute action of the first and second skewers 199A and 199C.

As a result, the grain straw of the crop C to be harvested is subjected to rake by the raking claws 159A and 159B in the guiding areas Aa1 and Ab1 of the respective hoisting devices 122A and 122B, It is possible to avoid the risk of being entangled with each other when viewed from the front of the vehicle body on the front side of the vehicle body in the hoisting areas Aa1 and Ab1 of the hoisting devices 122A and 122B, It is possible to prevent the efficiency from being lowered or the occurrence of defective raising.

As shown in Figs. 12, 13, 17, 21, and 22, the twin roll-up device 122B provided on the right-side raising frame 126B has its roll- And is located on the left side spaced apart from the operation section 102.

As compared with the case of equipping the right-side up-hoisting frame 126B with the twisting unit Ab2 positioned on the right side of the operation side, It is possible to improve the visibility to the front and improve visibility from the operation unit 102 to the workpiece in front of the vehicle body.

The left and right lifting devices 122A and 122B form the left and right widths Wa and Wb of the lift-up areas Aa2 and Ab2 thereof with a width corresponding to the maximum height of two pairs of grain straws. The claws 159A and 159B provided on the left and right lifting devices 122A and 122B are formed to have a long length corresponding to the wide roll-up areas Aa2 and Ab2.

As a result, when the grain straw passes through the corresponding lift-up areas Aa2 and Ab2 at the time of running the four-piece cutting operation in which the left and right roll-up devices 122A and 122B always lift up the two grain- It is possible to prevent the resistance from exceeding the allowable range. As a result, it is possible to smoothly and smoothly roll up the grain straw by the left and right roll-up devices 122A, 122B even in the case of four-piece cutting operation.

In addition, by forming each of the kicking claws 159A, 159B to have a length corresponding to the wide roll-up areas Aa2, Ab2, the roll-up claws 159A, 159B in the wide roll- 159A, and 159B can be prevented from forming dead zones that do not act on the grain straw. As a result, even though the respective roll-up regions Aa2 and Ab2 of the left and right roll-up devices 122A and 122B are formed at a wide width allowing the passage of two sets of grain straws, the left and right roll-up devices 122A and 122B It is possible to reliably raise the grain straw.

Incidentally, only the left-side raising device 122A to which two sets of grain straws are fed is always set to the left-right width Wa of the raising area Aa2 irrespective of the working route of the three- May be configured to have a wide width corresponding to the height of the maximum of two pairs of grain straws and the length of the toe-up claw 159A corresponding to the wide jump-up area Aa2.

As shown in Figs. 11, 14 and 16 to 18, the training drive device 170 is disposed at the right end of the intermediate member 135 so as to be positioned at the right end of the preload 103. As shown in Fig. This makes it possible to prevent the problem that the cut straw after being cut is entangled in the cutter driving device 170, which may be caused when the cutter driving device 170 is disposed on the left and right central sides of the pre- In the case where a non-cropped crop Cx exists only on the left side of the base 101, which may be caused by placing the cutting tool 170 on the left end of the preload 103, , It is possible to avoid occurrence of a problem that the uncut crop Cx is entangled with the cut-off day driving device 170 in advance.

The feed conveying device 125 is disposed at the left position in the preloading section 103 so that the grain straw conveyed by rake to the grain straw passing section 127 is fed and conveyed toward the threshing device 104 on the left side of the vehicle body, The left and right balance of the preload portion 103 can be improved by disposing the relatively large-sized power saving drive device 170 at the right end portion of the preload portion 103 where the left side becomes heavy.

A cover 211 made of a metal plate is disposed on the right side end of the preloading section 103 to cover the trim machine driving device 170. The cover 211 is formed by two bolts 212 on the upper side among the three bolts 212 connecting the right side divider 121B to the right end of the intermediate member 135, (199B) to the left end of the right hand side of Fig.

By this means, the uncut crop Cy on the right side outside of the vehicle body by the right split minute 199B and the cover 211 when the unfinished crop Cy exists on the right side outside of the base 101, It is possible to avoid the risk of getting tangled in the cutter driving device 170 in advance.

The installation efficiency can be improved as compared with the case where the right side divider 121B and the right minute divider 199B and the cover 211 are separately bolted to the right end of the intermediate member 135. [ Further, when the right minute interval 199B or the cover 211 is exchanged, it is possible to exchange them while preventing the right side divider 121B from being completely separated from the right end of the intermediate member 135 .

11 to 13, the side frame 213 located at the front right end of the base 101 has its front half portion close to the right end 113Ba of the right crawler 113B by the front end portion side So as to be inclined in the lateral direction of the vehicle body. The outer side surface 213a of the side frame 213 is connected to the outer side of the uncut crop Cy on the right side of the vehicle body at the time of traveling under heavy work where the uncut crop Cy exists on the right outer side of the base 101 And can function as a guide surface guiding to the right outside of the vehicle body. As a result, it is possible to prevent the uncut crop Cy existing on the right side outer side of the base 101 from being wrapped to the inside of the vehicle together with the right split second 199B.

By the way, in the left and right rake conveying devices 124A and 124B, the left and right rake conveying mechanisms 171A and 171B carry rake of the grain straw by the rake belts 174a and 174b made of rubber, The protrusions 174a and 174b of the rake belts 174a and 174b are deformed to be less than the strength of the grain straw before cutting and by this deformation, The grain straw is not conveyed to the grain straw passing portion 127 by rake. Further, by the running of the work at this time, the grain straw before cutting is pressed and bent toward the front of the vehicle body.

When the pushed-down grain straw is cut and reached the cutting position of the cutting device 123, the cutting action is performed by the restoring action of returning to a straight-spread state in a bent state by pressing toward the front of the vehicle, 171B of the left and right rake transport mechanisms 171A, 171B and out of the conveying region of the left and right rake transport mechanisms 171A, 171B.

When such a phenomenon occurs, the grain straw overflowing in front of the cutting device 12 is fed to the next uncut grain straw which is sequentially introduced toward the carrying region of the left and right rak transport mechanisms 171A, 171B To the cutting position of the cutting device 12, and the bottom side thereof is cut again with the uncut grain straw.

If such a grain straw is cut twice, the length of the grain straw will not be uniform, and this will result in a poor alignment of the grain end when the grain straw is transported toward the threshing device 104, The residual threshing tend to occur at the time of the threshing process, and as a result, the efficiency of recovering the grains is liable to be lowered.

Therefore, as shown in Figs. 17, 18, 22, and 23, in this combine, the left and right rake transport mechanisms 171A and 171B of the left and right rake transport apparatuses 124A and 124B are transported The inclination angles? A and? B in the vehicle body left and right directions with respect to the vehicle longitudinal direction of the paths 214A and 214B are made equal. The narrow angle? A between the linear transporting path 214A of the left rak transporting mechanism 171A and the linear transporting path 214B of the right raking transporting mechanism 171B is larger than the narrowing angle? The left and right rake transport mechanisms 171A and 171B and the supply and conveyance apparatuses 125 and 125B are formed so as to be larger than the narrow angle &amp;thetas; B between the straight transport path 215 of the base- ) Is set.

When the posture of the left and right rake transport mechanisms 171A and 171B is set in this manner, the linear transporting paths 214A and 214B thereof are positioned above the cutting device 123, and the plurality of movable blades 168 and the fixed blade 169 are arranged so as to be continuously arranged in a straight line in the left-right direction, the cutting positions of the movable blades 168 and the fixed blades 169, which are arranged in a straight line in the left-right direction, As shown in FIG.

This makes it possible to effectively suppress the left and right rake conveying devices 124A and 124B from acting on the grain straw before cutting by the cutting device 123 so that the left and right rake conveying devices 124A and 124B It is possible to effectively suppress the deterioration of the recovery efficiency of the curled grains due to the action.

Further, the grain straw immediately after cutting by the cutting device 123 can be rake-conveyed by the left and right rake conveying devices 124A, 124B toward the grain straw passing portion 127 as a result, 124A, 124B can improve the rake transport efficiency of the grain straw.

17 and 22, the right and left packers 172A and 173B are provided on the guide members 173A and 173B of the left and right rake conveying units 124A and 124B from the right and left ends of the pre- And linear guide portions 173A and 173B extending toward the rotation center of the guide portions 172A and 172B. Each of the linear guide portions 173A and 173B is formed in a horizontal straight line shape that is perpendicular to the longitudinal direction of the vehicle body.

This makes it possible to prevent the straight guide portions 173A and 173B of the right and left guide members 173A and 173B from acting on the grain straw before cutting in running the work and pushing the grain straw toward the front of the car body. As a result, it is possible to avoid the possibility that the plowed grain straw overflows to the front of the cutting device 12 and is cut off twice by the restoring action from the pushed state with the cutting.

As shown in Figs. 12 and 23, the supplying and conveying device 125 sets the conveying posture so that the conveying end portion 125b overlaps with the operating portion 102 when viewed from the front of the vehicle body. As a result, the position of the preload portion 103 in the left-right direction of the vehicle body is matched to the two-frame, four-frame trimming specification, and the left and right ends 113Aa of the left crawler 113A of the left dividers 121A And the position in the lateral direction of the vehicle body substantially coincides with the fulcrum start end 121Ba of the right side divider 121B and the right end 113Ba of the right crawler 113B, The conveying start end portion 125b of the feeding and conveying device 125 can be directly connected to the grain straw passing portion 127 to be placed in the grain straw passing portion 127, And can be positioned at a position immediately behind the front end 127 of the housing.

In other words, even if the auxiliary transport device for relaying the delivery of the grain straw is not provided between the left and right rake transport devices 124A and 124B and the supply and conveyance device 125, It is possible to obtain a supply and conveying structure suitable for the above-described embodiment.

The operation unit 102 is provided with a conveying start end 125b of the supply conveying device 125 and a conveying start end 125b of the conveying device 125 on the front end portion of the side panel 115 overlapping with the conveying end 125b of the conveying device 125, The recess portion 102a is formed in the recess 102a.

The supply and conveyance apparatus 125 is arranged so that the linear conveying path 215 of the base cooperating and conveying mechanism 182 with respect to the longitudinal direction of the vehicle body is set so that the conveying end portion 125b thereof flows into the concave portion 102a of the operation portion 102, The inclination angle? C in the lateral direction of the vehicle body and the inclination angle? D in the lateral direction of the vehicle body of the straight conveying path 216 of the trailing end edge conveying mechanism 183 with respect to the longitudinal direction of the vehicle body.

This makes it possible to bring the transportation start end side of the supply and conveyance apparatus 125 closer to the operation section 102 as compared with the case where the recess 102a is not formed in the operation section 102, 125 can be shortened in the longitudinal direction of the vehicle body, and the overall length of the combine can be shortened.

The operation lever 198 of the support frame 190 of the supply and conveyance device 125 is moved toward the operation section 102 by the conveyance end side of the supply and conveyance apparatus 125, The operation lever 202 is further brought closer to the operation section 102. As a result, the operation of the operation lever 198 for controlling the tread depth from the operation section 102 becomes easier.

When the inclination angles? C and? D in the vehicle body horizontal direction with respect to the longitudinal direction of the vehicle body conveyance device 125 are increased, the supply and conveyance device 125 approaches the left rak transportation mechanism 171A. As a result, there is a possibility that the bottom side of the grain straw conveyed by the feeding and conveying device 125 comes into contact with the left rak transport mechanism 171A, and the conveying posture of the grain straw is disturbed.

Therefore, as shown in Figs. 10, 11, 14-16, and 18, in this combine, the left rak transport mechanism 171A is arranged so as to be lower in height than the right rak transport mechanism 171B . This makes it possible to prevent the bottom side of the grain straw conveyed by the feeding and conveying device 125 from coming into contact with the left side rak transport mechanism 171A to prevent the conveying posture of the grain straw from being disturbed, , The grain sorting is made worse when the grain conveying device 125 conveys the grain straw toward the threshing device 104, and the grain recovery tendency is liable to occur in the threshing process in the threshing device 104 Can be prevented.

Further, when the left rak transport mechanism 171A is configured for two cartridges and the inclination angles? C and? D in the vehicle body transverse direction with respect to the vehicle longitudinal direction of the supply and conveyor device 125 are increased, The grain straw that has been picked up by the raking mechanism 126A on the left side is transported in a substantially U shape by the rak transport mechanism 171A on the left side and the supply and conveyance device 125. [ Therefore, in the grain straw passage portion 127, which becomes the switching point of the grain straw conveyed in the substantially U-shape, the bottom side of the grain straw tends to be swung greatly by the centrifugal force.

Therefore, as shown in Figs. 10, 11, 15 to 19 and Fig. 22, in this combine, a connecting portion 135A in the front-rear direction is interposed between the extending member 134 and the intermediate member 135 The left and right rake transfer devices 124A and 124B transfer the extended member 134 from the feeding passage device 127 to the intermediate member 135 by separating the extension member 134 from the grain straw passage 127 to the rear side of the vehicle body. 125 to allow the passage of the bottom side of the grain straw.

This makes it possible to prevent the bottom side of the grain straw from coming into contact with the extending end of the extending member 134 even if the bottom side of the grain straw is greatly swung by the centrifugal force in the grain passing portion 127, It is possible to prevent deterioration of the grain recovery rate such that the alignment of the grain ends of the grain straw is deteriorated due to the disturbance of the conveying posture of the grain straw due to the contact so that the residual threshing tendency is likely to occur in the toning process in the toning apparatus 104 .

The extension member 134 is arranged so as to be located on the left end side of the preloading section 103 rather than the grain straw passing section 127. This makes it possible to reliably prevent the bottom side of the grain straw, which is greatly swung by the centrifugal force, from contacting the extending end of the extending member 134 in the grain straw passing portion 127 more reliably, It is possible to more reliably prevent the deterioration in the recovery rate of a single grain.

The guide members 173A and 173B of the left and right rak conveying devices 124A and 124B are formed so as to guide the bottom side of the grain straw passing through the grain passing portion 127 toward the feeding and conveying device 125, The guide end portion 73c of the left guide member 173A is fixed to the support member 136 and the guide end portion 73d of the right guide member 173A is fixed to the extending end portion of the extension member 134 have.

Therefore, even if the bottom side of the grain straw is greatly swung by the centrifugal force in the grain passing portion 127, the bow can be effectively suppressed by the right side guide member 173B, and the bottom side of the grain straw And the right and left guide members 173A and 173B can quickly and surely deliver the same to the base cooperating and conveying mechanism 182 of the feeding and conveying device 125. [ As a result, it is possible to prevent degradation of the grain recovery rate due to cereal straw clogging due to defective delivery and disturbance of the delivery posture of the grain straw due to defective delivery.

As shown in Figs. 15, 18, and 22, a lower end portion of the grain straw to be delivered from the left and right rak transport devices 124A and 124B to the supply and conveyance device 125 is received above the connecting portion 135A The supporting plate 218 is supported so as to extend from the extending end of the extending member 134 to the intermediate member 135.

This makes it easier to align the bottom side of the grain straw from the left and right rak transport devices 124A and 124B to the supply and conveyance device 125. [ As a result, the grain ends of the grain straws are aligned, making it less likely that the grain remains in the threshing process in the threshing device 104, and the recovery rate of the grain can be improved.

Fig. 28 is a left side view of the preload 103 showing another form of the preload 103; and Fig. 29 is a front view of the preload 103 showing another form of the preload 103. Fig. As shown in these drawings, the preloading unit 103 is provided between the left side finishing tool 151A and the left side uplifting apparatus 122A at the left end thereof by exchanging the left side divider 121A, And the like.

As shown in Figs. 14, 28, and 29, the squeezing device 219 is provided with the power taken out through the auxiliary transmission mechanism 220 of the bevel gear type from the input shaft 153A of the left shunting device 122A . &Lt; / RTI &gt; The driving causes the driving endless chain 223 to rotate around the driving sprocket 221 disposed at the upper portion thereof and the driven sprocket 222 disposed at the lower portion thereof so that a constant The leftmost crop Ca in the working width of the preloading section 103 and the crop Cx other than the left working width adjacent to this crop Ca are separated by the plurality of roll-up claws 224 arranged in the pitch, ).

That is to say, by equipping a drive-type squeezing device 219 between the left sowing cutter 151A and the left sowing device 122A, the leftmost crop Ca in the working width of the preload 103, It is possible to improve the milling accuracy and the milling efficiency of the crop Ca and the crop Cx other than the working width on the left side adjacent to the crop Ca. This effect is particularly conspicuous when the harvesting operation is carried out in a package in which the crop C is highly dressed.

The squeezing device 219 is equipped with an inclined posture inclined toward the inside of the vehicle body in the lateral direction of the vehicle body. As a result, the leftmost crop Ca in the working width of the preloading section 103 and the crop Cx outside the working width on the left adjacent to the crop Ca are mixed while the leftmost crop in the working width Ca can be gathered toward the swelling area Aa1 of the left shunting device 122A.

As a result, the height of the crop C and the height of the cropping by the left-side tilting apparatus 122A can be improved. This effect is particularly conspicuous when the two crops C are lifted up by the left-side lifting device 122A.

As a result, the left and right rake transfer devices act on the crop straw before cutting by the cutting device, so that it is possible to effectively suppress the bending of the crop straw before cutting by pushing the straw forward. As a result, by the restoring action to return from the bent state to the straightly extended state when the pressed crop straw reaches the cutting location of the cutting device and is cut, It is possible to effectively suppress the cutting of the crop straw twice due to the fact that it protrudes in the front direction and is released from the conveying region of the left and right rak transport device and overflows to the front of the cutting device.

This is particularly effective when two crop straws are introduced into the hoisting frame, that is, when a plurality of crop straws are introduced into the hoisting frame at a transplanting interval in the left and right direction, and from the grain straw passing portion in the hoisting frame It is possible to effectively suppress the pushing and bending of the crop straw introduced into the left and right side portions of the separated side by the action of the conveying leading end side of the rak transport device located on the front side of the vehicle body.

In addition, since the crop straw immediately after cutting by the cutting apparatus can be rake-fed quickly toward the grain straw passing portion by the right and left rak transport devices, the crop straw can be smoothly transferred to the supply and conveying apparatus in the good state have.

Therefore, it is possible to prevent the deterioration of the recovery efficiency of the curled grains due to the cutting of the crop straw twice, and at the same time, the conveying efficiency of the crop straw in the pre-installation portion can be improved.

Preferably, the rake transfer device on the side remote from the operation part is positioned higher than the rake transfer device on the operation side. This is advantageous in the following respects.

In the case where the feeding and conveying device is disposed close to the raking device on the side remote from the operation part, there is a problem that the bottom side of the crop straw conveyed by the feeding and conveying device contacts the rake conveying device and the conveying posture is disturbed There is a possibility of causing it.

Therefore, in the present embodiment, the rak transporting device on the side remote from the operation portion is disposed so as to be positioned higher than the rak transporting device on the operation portion side. Thus, under the crop straw transported by the supply transporting device It is possible to make the eastern side difficult to contact with the rak transporting device on the side remote from the operation portion and to prevent the conveying posture of the crop straw from being disturbed due to the contact.

As a result, alignment of the grain ends of the crop straw becomes worse when the crop straw is transported toward the threshing device by the supply and conveyance device due to the disturbance of the transporting posture, and the threshing residue easily occurs in the threshing process in the threshing device Can be prevented.

Therefore, it is possible to prevent degradation of the gravitol recovery efficiency due to contact of the crop straw conveyed by the supply and conveyance device with the rak transport device on the side remote from the operation section.

According to this characteristic configuration, the linear guide portion of the right and left guide members can be prevented from bending the crop straw against the front of the car body by acting on the crop straw before cutting at the time of running the job. As a result, it is possible to avoid the possibility that the plowed crop straw is overflowed to the front of the cutting device and cut out twice by the restoring action from the forced bending state together with cutting.

Therefore, it is possible to prevent the deterioration of the recovery efficiency of the grains by the cutting twice of the crop straw caused by the action of the guide member on the crop straw before cutting.

Further, the combine according to the present embodiment is characterized by the following configuration. That is, it is preferable that: - a cutting part is connected to one side of the base body and an operation part is formed on the other side of the base body; a tilting device is arranged at a rear position of the tilting part of the base body; A pair of right and left raising frames are formed by disposing the two dividers and a pair of right and left raising devices so that a raising device is positioned between two adjacent dividers to form a pair of left and right raising frames, And a rake transfer device for rake-transferring the grain straw of the crop cut by the cutting device of the pre-loading part to the grain straw passing part formed between the right and left raising frames, wherein the rake- And a feeding and conveying device for feeding the grain straw of the crop conveyed to the grain straw passing part by the device to the threshing device, And an intermediate member connected to the extending end of the extending member, wherein the intermediate member is provided with a supporting member for supporting the right and left rake carrying devices And a divider positioned adjacent to one side of the left and right sides of the side separated from the operation unit and a divider adjacent to the divider so that a maximum of two crop straws can be introduced therebetween And the rake-raising device located between the two dividers is configured so as to be capable of raising up to two sets of crop straws, A maximum of two pairs of crop straws can be carried on the rake, Is connected to the extending end of the extending member through a connecting portion in the forward and backward direction, and the connecting member is provided between the intermediate member and the extending member, And a transfer path for allowing passage of the bottom side of the crop straw to be transferred from the transfer device to the supply and conveyance device is formed.

According to this characteristic configuration, the cut-off portion is constituted by at least two trillion 2-frame, three-trillion cut-off specimens, in which at least two kick-up frames on the side remote from the operation portion can be rolled up to two sets of crop straw . When the cutting portion having a wide working width is fixedly disposed on the front surface or almost directly on the front surface of the base body, it is possible to prevent the cutting work from being carried out during a heavy work operation in which uncut crops are present outside the left and right sides of the base body, Crops existing within the width of the vehicle body can be easily harvested irrespective of the work traveling of the surrounding cuttings where the uncut crops are present outside.

In addition, by constructing the lift-up frame on the side separated from the operation section for two tanks, it is possible to prevent the occurrence of unfinished cropping on the outside of the vehicle body at a distance from the operation section, There is always a hoisting frame that lifts up two sets of crop straws regardless of the operation of the surrounding cutting work where the crop exists.

As a result, the contact causes disturbance in the conveying posture of the crop straw when it is transmitted to the feeding and conveying apparatus, resulting in deterioration in alignment of the end of the crop straw conveyed by the feeding and conveying apparatus, It is possible to prevent a decrease in the recovery rate of the curl such that the residual threshing is likely to occur.

Therefore, it is possible to provide a harvesting machine which is capable of harvesting crops with a greater number of tillers than the number of shoveling frames formed on the harvesting section, It is possible to prevent deterioration of the recovery rate of the curled yarn due to contact of the crop straw with the extension member.

Preferably, a supporting plate is provided above the connecting portion to receive and support the lower end portion of the straw conveyed from the rake carrying device to the feeding and conveying device from below.

According to this characteristic configuration, it is possible to easily align the bottom side of the crop straw to be transferred from the left and right rak transport devices to the supply and conveyance device. This makes it easier for the end of the grain of the crop to be aligned, making it less likely that the threshing remains in the threshing process in the threshing device.

Therefore, the curved recovery rate can be improved.

Preferably, the rake transfer device is provided with a guide member for guiding the grain straw of the crop to the rake transfer area, and the guide of the guide member provided on the rake transfer device on the operation part side And the end portion is fixed.

According to this feature, even when the crop straw which is rake-transported by the rake transporting device on the side remote from the operation section is transported by the centrifugal force by the centrifugal force in the grain straw passing section, The portion can be effectively suppressed by the guide member fixed to the extending member. As a result, the crop straw can be quickly and surely delivered to the feeding and conveying device.

Therefore, it is possible to prevent the cereal straw clogging due to the defective transfer from the rake transfer device to the supply and conveying device, and the drop in the recovery rate of the curled product due to the disordered conveying posture of the straw by the defective transfer.

Preferably, the extension member is disposed so as to be located at a side of the left and right side end portions spaced apart from the operation portion in the pre-installation portion with respect to the grain straw passage portion.

According to this characteristic configuration, even when the crop straw which is rake-transported by the rake transporting device on the side remote from the operation section is transported by the centrifugal force in the grain straw passing section, It is possible to more reliably prevent the crop straw from coming into contact with the extending member.

<Summary of Third Embodiment>

If the lid disclosed in Patent Document 1 is used as the lid of the inspection opening, since the lid is provided on the lid, it is easy to make the inspection opening large and easy to use.

That is, when the lid is not provided with a trailing edge, since the inspection opening is provided to avoid the ridge arranged in the circumferential direction and the rotational axis direction of the lid drum, the inspection opening tends to be small, or it may become slender or curved.

On the other hand, even if the size and the shape of the inspection opening are set not depending on the trailing edge, when the lid is provided with the lid, the lid is provided with the lid by the lid in the position where the lid of the lid is to be installed do.

In the case of employing a lid provided with a feeder, problems arise with regard to the structure and arrangement of the lid and the feed dog, depending on the configuration of the lid provided on the drill drum.

42, if the lid 334 is configured to be in contact with the surface of the peripheral wall 332 of the slide drum so as to be connected to the lid 334, The entire lid 334 is positioned on the outer side of the ramp 331 of the ramp 334 and the ram 336 provided on the lid 334 is supported on the peripheral wall 332 of the ramp And the trailing edge 336 of the lid 334 is brought into a state of being very close to the water pipe 311. As a result,

When the lid 334 is brought into contact with the surface side of the peripheral wall 332 of the slide drum 334, the periphery of the lid 334 is exposed on the surface side of the peripheral wall 332 of the drum. The abrasion due to the contact with the grain straw or the curved portion tends to occur at the portion located below the check opening 333 in the peripheral portion of the opening 333 in the direction of the tilting rotation.

The portion connecting the spray 336 of the lid 334 to the peripheral wall portion of the slide drum 334 can be prevented from being damaged Even if the lid 334 is provided with a structure displaced to the inside of the ramp 331 relative to the portion connecting to the inner wall 332 of the drum 332, the ladder 334 of the lid 334, It may be closer to the water pipe 311 than the water level 335 of the water pipe 332.

Therefore, in order to provide a thruster for the threshing device which can be provided with a large and easy-to-use inspection opening and which can avoid the abnormal close-up of the lid wear and tearing, , In the combine according to the third embodiment, the feed for the threshing device has the following characteristic configuration.

In other words, in the case of the above-mentioned elevation for the threshing device having the inspection opening provided on the peripheral wall of the slide drum and the detachable lid for closing the inspection opening, the lid is provided with the lid on the peripheral wall, A connection surface for contacting the back surface of the cover portion and connecting the connection surface to the back surface of the peripheral wall portion of the connection portion; Is set to be a surface.

According to this configuration, even when the size or shape of the inspection opening is set not depending on the trailing edge, in the state where the lid is provided, the trailing edge of the cover is provided by the lid portion of the lid at the position where the trailing edge of the ram is to be installed.

In a state in which the lid is provided, the connecting portion of the lid is connected to the back side of the peripheral wall portion of the drum and is not exposed on the surface side of the peripheral wall portion. Instead of being exposed to the surface side of the peripheral wall portion, The circumferential portion of the lid does not come into contact with the curled-leaf.

Further, in a state in which the lid is installed, the lid of the lid is located at a position where the lid is introduced into the peripheral wall portion of the drill drum, and the lid pitch is supported at this position. As a result, the urging force located on the lid is not projected more toward the water receiving side than the urging force of the urging force acting on the peripheral wall of the sliding drum. Even if the position of the lid part relative to the peripheral wall part of the lid part is changed in accordance with a manufacturing error of the lid part, the lid positioned on the lid part does not protrude to the water side more than the ridge part positioned on the peripheral wall part of the lug drum.

Therefore, it is possible to efficiently install or replace the feed dogs by installing the check openings in a large and easy-to-use state, and also to provide a simple structure in which the lid is connected to the connecting surface of the connecting portion and the surface of the lid portion, It is possible to avoid high-precision close proximity to the water level of the tare, and at the same time, it is possible to obtain a high-quality swing for the threshing device which does not cause wear due to contact with the grain straw or the curved lid of the lid.

Preferably, a connecting port is provided for connecting the connecting portion of the lid and the peripheral wall portion of the sliding drum by tightening, and the connecting port and the peripheral wall portion arranged in the urging rotational direction on the upper side of the checking opening The gap between the opening and the opening is set to be larger than the gap between the connecting hole arranged in the urging rotation direction and the inspection opening perimeter of the peripheral wall portion in the lower side in the tilting direction.

According to this configuration, when the lid is provided on the back side of the peripheral wall portion of the slide drum, the periphery of the inspection opening in the peripheral wall of the drum is exposed, and around the inspection opening in the upper rotation direction The abrasion due to the contact with the straw or the curved shape is likely to occur. According to the configuration of the second aspect of the present invention, even if wear occurs around the inspection opening on the upper side in the direction of the tilted rotation with respect to the inspection opening, the abrasion progresses to the connection port and the installation of the lid becomes impossible. It can be prevented by the size of the gap between the inspection opening perimeter and the connector at the upper side.

Therefore, it is possible to prevent the lid from being installed due to the wear around the inspection opening of the rake drum, and to provide the raising for the threshing device which can be used over a long period of time, by providing the lid on the back side of the peripheral wall portion of the drum .

It is also preferable that the lid is provided on the surface of the lid part with a protrusion located in the inspection opening along the periphery of the inspection opening toward the lower side in the direction of rotation of the peripheral wall part in the state in which the lid is closed.

According to this configuration, in the state in which the lid is provided, the projecting portion provided on the lid portion is located in the inspection opening along the periphery of the inspection opening toward the lower side in the tumbling rotation direction and serves as a guard means around the inspection opening, It is possible to prevent the protruding portion from abutting against the check opening.

Therefore, the lid is provided on the back side of the peripheral wall portion of the drum, and the abrasion due to contact with the grain straw or the curved portion around the inspection opening of the drum is prevented, .

As shown in Fig. 44, a treatment copper 417 is provided below and behind the sweep 403 to release the treated material discharged from the rear end of the sweep 403 by the treatment copper 417, So that the grains are extracted from the dust. A backward fan 414 is provided behind the processed copper 417 and an upper fan guide 414 is provided to cover the upper side of the backward fan 404. [ A shielding member 420 to be described later is provided over substantially the entire width between the left and right side walls 418 and 418 below the lower fan guide 415 which covers the lower side of the dustproof fan 404, Is disposed at the rear end portion of the sheave case 416 located in the vicinity of the upper end of the sheave case 416 so as not to interfere with the swinging motion of the shielding member 420 to be described later.

Fig. 45 is a longitudinal side elevational view of the sweeping rod 403 showing the details of the sweeping bar 431 forming the stretch shrinkage level 431a at the tip end portion. Fig. 46 shows a rear end elevational view of the sweeping tongue 403.

The front end wall 430a and the intermediate wall 430b of the drum 430 of the ram 403 with the trailing edge 432 are fixed to the ramp rotation axis 433 and the rear end wall 430c of the drum 430 The shaft portion protruded forward from the front wall 425 of the first chamber 400A of the first rotary shaft 433 is rotatably supported by a first fixing shaft 435 fixed to the rear wall 426 of the first rotary shaft 400A, And a pulley 434 is fixed. The first fixed shaft 435 is provided with a fixed bracket 436 and a second fixed shaft 435 in the form of a crank from the first fixed shaft 435 at a position lower than the first fixed shaft 435, And the rear end portion of the tilted rotary shaft 433 is rotatably supported on the shaft supporting member 441 fixed to the second fixed shaft 437. [ The two fixing shafts 431 are rotatably supported on the second fixing shafts 437 around the second fixing shafts 437. When the tips of the shredding bars 431 are positioned downwardly downward, When the leading end portion (stretch shrinkage trailing portion 431a) of the rod 431 is in the protruding posture protruding outward from the drum 430 of the ramp 403 and the hoisting bar 431 is positioned upwardly, The length of the tapping bar 431 is set to be a non-protruding posture from the drum 430 of the drum 403.

The base of the tumbling bar 431 is rotatably supported by the second fixing shaft 437 and the free end of the tumbling bar 431 is connected to a tumbling bar guide body 438, respectively. Thus, when receiving the rotational power from the input pulley 434, the pulley 403 rotates about the pulley 433 and the pulley 431 is guided to the pulley 423 of the drum 430 The second fixed shaft 431 rotates about the second fixed shaft 437 and protrudes outwardly of the drum 430 as the expansion and contraction level 431a of the free end is downward. 430, and enters the most in the vicinity of the upper end position as shown in Fig. By the expansion and contraction operation of the tread bar 431 as described above, the stretch shrinkage level 431a thins and falls the rice at the lower portion, and the tread bar 431 is in the vicinity of the upper end, 403), it is possible to efficiently perform the threshing process because the processed material to which the rice is attached is released and thrown away.

47 and 48, the shielding member 420 is provided with a shielding plate 421 formed of a plate-like body on the lower surface of the lower fan guide 415 provided between the left and right side walls 418 and 418 And the shielding plate 421 is suspended from the support member 422 by screwing the shielding plate 421 at a plurality of positions in the width direction.

48, the shielding member 420 is provided with a shielding plate 421 suspended from the support member 422 at an upper portion thereof. The shielding plate 421 is integrally connected with the upper portion in the width direction And a slit 419 which is divided into left and right portions at a plurality of positions in the width direction is formed at the lower portion thereof.

The shielding plate 421 is formed of a flexible, elastically deformable vinyl chloride resin.

As described above, the shielding member 420 is formed by a light-weight, elastically deformable resin so that the shielding member 420 is lifted rearward in accordance with the airflow rate of the air flow that is sent from the tuyere 410 toward the rear power outlet 427 It is configured to swing as if it were going down.

More specifically, the shielding plate 421 suspended from the support member 422 of the shielding member 420 is bent rearward largely in the state in which the wind amount of the tuyere 410 is maximized, And the large gap between the lower back plate 428 and the waste backing plate 428 causes the rice straw debris to be discharged to the outside of the gas.

Since the shield plate 421 is formed in the plurality of small width plate-like portions 421a in the width direction by the slits 419 cut in the vertical direction in the lower half of the lower portion excluding the upper end, The plate-shaped portion 421a in contact with the abutting portion has a greater amount of bending toward the rear than a portion where the airflow is weakly applied to the plate-shaped portion 421a, and an opening is formed according to the air volume. So that the processing efficiency is better than that of the conventional shielding apparatus without the insertion slit.

In the case of a light load at which the threshing process amount is small, the output is made weak and the air volume by the tuyeres 410 is weakened. At this time, the shielding member 420 closes the discharge port 427 to be shielded at will, and when the straw straw debris including the cornsteep which can not be recovered by the recovery device 400C is supplied from the front, the shielding member 420, The debris comes into contact, and the grains having a heavy specific gravity fall into the sheave case 416. The rice straw scraper with a light specific gravity is guided rearward through the shielding member 420 and the sheave case 416 by the selective wind supplied from the tuyere 410 even when it touches the shielding member 420. As described above, even when the repellent particles are to be discharged to the outside of the gas at a low flow rate, the discharge from the discharge port by the shielding member 420 is prevented and guided into the sheave case 416. Therefore, The loss can be reduced.

&Lt; Other Form 1 of Fourth Embodiment >

&Lt; Alternative Embodiment 2 of the Fourth Embodiment &

In the above-described embodiment, the shielding plate 421 is made of flexible vinyl chloride resin capable of being elastically deformed. However, in the case where the shielding plate 421 is constituted by a plate-shaped member having a small width divided from the upper end portion to the lower end portion The shielding plate 421 is made of hard vinyl chloride or other plate-like material which is hardly deformed by elastic deformation, and the plate-shaped body is held by a pressing member such as a coil spring in a non- And each of the plate-shaped bodies may independently rotate around the horizontal axis in accordance with the pressing force of the rice straw scraps at the time of operation.

&Lt; Alternative Embodiment 3 of the Fourth Embodiment &

In the above-described embodiment, the example in which the shielding member 420 is formed of a synthetic resin material of vinyl chloride is shown, but a thin synthetic rubber, a plastic plate, or the like may be employed as long as it achieves the same function .

&Lt; Fourth Embodiment of the Fourth Embodiment >

Although the slits 419 are formed in the shielding plate 421 in the embodiment described above, the slits 419 may be formed by cutting not only a predetermined length of a single shielding plate 421 with a cutter, It may be cut to form a gap. Further, in another aspect 1, a small gap may be formed between adjacent ones of the plate-shaped bodies adjacent to each other.

&Lt; Modification 5 of the fourth embodiment >

In the above embodiment, the shielding plate 421 of the shielding member 420 is formed of a single plate-shaped body made of a resin material of vinyl chloride. However, a thin plate-shaped body may be used as the plate- Two or more sheets may be stacked one on top of the other.

It is possible to change the opening degree with respect to the same air volume by changing the number of sheets to be overlapped with each other. Therefore, depending on the crop conditions to be harvested such as rice or wheat, for example, when the wheat is harvested, There is an advantage that it is possible to make the opening degree suitable for the crop condition.

<Other Forms>

In a state where the shielding plate 421 is elastically deformable by soft vinyl chloride or the like and the swing discriminating device 400B is driven to swing back and forth in a no-load state (a state in which no wind is selected by wind) The lower end portion of the shielding plate 421 is always in contact with the member (for example, the straw body 408) mounted on the sheave case 416 (the state in which the sheave case 416 is positioned at the lowest position) 416 in accordance with the shaking motion. By doing so, it is possible to prevent the shielding plate 421 from being sucked into the dust-exhausting fan 404, and at the same time, even in the working state in which the air- A gap is formed between the plate-shaped portions, so that it is possible to perform a good sorting while preventing the third loss.

<Summary of Fourth Embodiment>

As described above, the combine according to the present embodiment is characterized by the following arrangement. A tilting device is provided below the feeder and a tuyer is provided below the upper side of the conveying of the processed material of the shaking motion sorting device and the tuyeres feed the sorting wind toward the delivery port on the lower side of the conveyed object, And a shielding member capable of shielding the juncture and capable of being displaced to the lower side of the conveyed object. The shielding member is suspended from an upper portion of the support member, and the lower portion thereof can swing independently in the width direction And a plurality of plate-shaped portions having a plurality of plate-like portions.

According to this aspect, when there is a large amount of rice straw crumbs discharged to the outside of the machine by sorting, the shielding member is largely backwardly displaced by the strong sorting wind, and the delivery port is largely opened. In addition, when the amount of processing to be sorted and processed at the time of turning of the gas becomes small, and the airflow amount of the selective air supplied from the tuyere is reduced, the shielding member is swung in the closing direction, and the opening of the dust outlet is narrowed.

When the threshing throughput is decreased, the rice that has moved to the vicinity of the discharge port tends to be repelled (bounced) and is likely to be discharged to the outside of the gas even if the output of the rice is lowered and the selected air volume by the tuyeres is made somewhat lower. According to the feature, the rice to be discharged to the outside of the gas is inhibited from being discharged by the shielding member to the outside of the gas. On the other hand, since the shielding member is formed of a plurality of plate-like portions suspended from the support member at its upper portion and capable of swinging independently in the width direction at the lower portion thereof, the rice straw scraps discharged toward the power- Not only the lower space where the members are narrowed but also the plurality of plate-shaped portions are shaken or the side portions are turned and are discharged to the outside of the gas from the gap between the expanded plate-like portions. Therefore, the recovery of rice can be performed well by the shielding member, It is possible to reduce the loss and to discharge the rice straw crumbs to the outside of the gas without causing clogging, thereby improving the sorting efficiency.

Therefore, by forming the lower portion of the shielding member into a plurality of plate-like portions capable of independently swinging in the width direction, it is possible to prevent the discharge of the rice straw debris from being obstructed at a high flow rate with a large throughput, When a low flow rate with a small throughput is obtained, even if the output (selected air flow rate) is reduced, the small plate-shaped portions tend to rise easily, and a clearance is easily generated between adjacent plate- But it was able to effectively prevent the third loss.

In order to achieve such an effect, in a preferred embodiment, the shielding member is formed as a plate-like body capable of being elastically deformed, the upper portion is integrally connected to the width direction, and the lower portion thereof is divided into a plurality of slits Shaped plate-shaped portion. In another preferred embodiment, the plate-like portion of the shielding member is constituted by a plurality of small-width plate-shaped bodies divided from the upper end portion to the lower end portion.

It is also advantageous that the shielding member is made of a synthetic resin made of vinyl chloride.

According to this configuration, although the shielding member can be made of hard vinyl chloride, if it is made of soft vinyl chloride, it is flexible enough to partially flake the side with the slit so that the air volume is reduced, It is possible to improve the function of the backward movement.

It is also advantageous that the shielding member is configured to overlap two or more plate-shaped members.

According to this, for example, in the case of a relatively heavy crop, two or more plate-shaped bodies may be stacked so that the plate-shaped bodies can not easily be lifted up. This makes it possible to reduce the amount of the relatively heavy crop to be discharged by easily flipping the plate-shaped body. On the other hand, in the case of a relatively light crop (such as wheat), it is preferable to reduce the number of overlapping of the plate-shaped bodies or to make one plate-like body without overlapping so that the plate-shaped bodies can be easily turned up. This makes it possible to reduce the situation in which relatively light rice straw scraps can not be discharged because they can not be lifted up.

INDUSTRIAL APPLICABILITY As described above, the present invention can be applied to a spindle-type combine, in which the bottom end of the cut grain straw is held and conveyed by the feed chain and the end of the spindle is subjected to a treading process by a till. Further, the configurations of the respective embodiments can be employed in the same combine unless they are contradictory.
