Description

  The present invention relates to a combine that threshs a harvested cereal and selects and collects fine grains from the cereal, and more particularly, to a structure of a catching member provided at the bottom of a threshing apparatus. .

  In a conventional combine, a threshing device including a handling cylinder for threshing cereals and a selection mechanism arranged below the handling cylinder is stored in a traveling machine supported by a pair of left and right traveling crawlers, and the grain is stored. And a grain tank for it. At the bottom of the threshing device, the left and right horizontally long first receiving bowl with the first conveyor for transporting the first thing (grains after threshing), and the second thing (grains with branches, cut grains, etc.) Left and right horizontally long second receiving rods incorporating a second conveyor for conveyance are arranged in parallel. The first item collected in the first bowl is accumulated in the grain tank through the first conveyor. The second item collected in the second receiving bowl is returned to the threshing device via the second conveyor and the like and re-sorted.

By the way, in this type of combine, for example, when the type of grain to be harvested and threshed is changed, or when the season of rice harvesting is turned off, it is inconvenient if residual grains such as threshed grains remain in each receiving basket. Therefore, as a configuration for facilitating cleaning of the receiving bowl, as shown in Patent Document 1, a cleaning long hole extending along the longitudinal direction is formed in the bottom plate of each receiving bowl. . A configuration is disclosed in which a horizontally long lid cover body that closes the cleaning long hole is attached to the lower surface side of each receiving rod so as to be capable of opening and closing around a horizontal axis extending along one longitudinal side portion of the receiving rod. Each lid cover body was opened and rotated around the horizontal axis, and the residue in each receiving bowl was dropped and removed from the cleaning long hole opened toward the ground.

  However, according to the configuration of Patent Document 1, each lid cover body having a substantially lower semicircular cross section is opened and rotated around a horizontal axis parallel to the longitudinal axis of each receiving rod. Therefore, the lid cover body is opened. Since the lid cover body is inclined so that the free end side of the lid cover body faces downward, most of the residue in each receiving basket does not collect in the lid cover body, or on the ground such as a farm field or on a traveling crawler. Will fall down. For this reason, when collecting the residue, for example, a wide sheet is laid in advance between the left and right traveling crawlers and below the receiving rods, and the residue is dropped and collected on the wide sheet. There was a problem that it was extremely troublesome, and it took time to collect it.

  In addition, since each lid cover body having a substantially arc-shaped cross section opens and rotates around a horizontal axis parallel to the longitudinal axis of each receiving rod, it is necessary to check whether each lid cover body is open or closed. Had to bend near the combine and look into the bottom of the threshing device, and there was a problem that it was difficult to grasp the open / closed state of each lid cover body easily and quickly.

  In particular, when the combine is run without forgetting to close the lid cover body, the lid cover body may be caught in the rotation of the running crawler and broken. In addition, when the harvesting and threshing operation is performed without forgetting to close the lid cover body, there is a risk that the threshing may be scattered from the long holes for cleaning of the receiving bowls to the field.

In the first half of the time when the two lid cover bodies 103 and 104 are pulled out (until the connecting guide shaft 122 passes the location of the regulation piece 125), the longitudinal middle portions of the lid cover bodies 103 and 104 correspond respectively to the regulation pieces 125 corresponding thereto. The contact piece 125b is slid from above and supported (see FIG. 9). Therefore, until the connection guide shaft 122 passes the restriction piece 125, the opening angle of the lid cover bodies 103 and 104 with respect to the lower surfaces of the receiving rods 21 and 22 is restricted.

  Next, an example of the aspect which cleans each receptacle is demonstrated. Here, it is assumed that the blindfold side cover body 98 (see FIG. 5) mounted on the outer surface side of the other side wall in the threshing device has been removed in advance.

  First, while holding the grip portion of the handle member 107 with one hand, the other hand holds the vertical axis portion of the operating rod 110, and the operating rod 110 is removed from the threshing device 5 against the pressing biasing force of the compression spring 113. Pull in a direction away from the side wall 5b. Then, the hook-shaped latch claw 111 in the operating rod 110 is detached from the grip portion of the handle member 107, and the one end portion of the both lid cover bodies 103 and 104 connected by the beam member 106 and the other side wall 5b of the threshing device 5 are connected. The connection is released. In this manner, the lid cover bodies 103 and 104 can be switched from a closed posture (see FIGS. 5 to 7) in which the corresponding long holes 101 and 102 are respectively closed to an open posture shown by a solid line in FIG.

  Next, the hand gripping the grip portion of the handle member 107 is slightly pushed down, or by the dead weight of the lid cover bodies 103 and 104, the longitudinal halfway portions of the lid cover bodies 103 and 104 respectively contact the corresponding regulating pieces 125. The two lid cover bodies 103 and 104 are swung downward (rotated) around the connection guide shaft 122 together until they contact the contact piece 125b (see the solid line state in FIG. 9). As described above, the free end sides of the lid cover bodies 103 and 104 (the side where the handle member 107 is disposed) face downward, but when the inclination angle exceeds a predetermined angle, the lid cover bodies 103 and 104 are placed on the upper surfaces of the lid cover bodies 103 and 104. The remaining residue slides down to the free end side (opening end 103a, 104a side) of the lid cover bodies 103, 104. In order to prevent such a state, normally, a collection bucket is disposed outside the traveling crawler 2 on the side where the lid cover bodies 103 and 104 are disposed, and the operator has a grip portion of the handle member 107. The two lid cover bodies 103 and 104 are pulled out to the side in the state of the solid line in FIG. 9, and when fully pulled out, the free ends of the two lid cover bodies 103 and 104 are lowered, The residue on the upper surface of 104 may be dropped into a recovery bucket or the like.

  Due to the presence of the restricting piece 125 corresponding to each lid cover body 103, 104, both lid cover bodies 103, 104 do not swing downward about the connection guide shaft 122 any more. Accordingly, it is possible to reliably avoid the interference between the both lid cover bodies 103 and 104 and the traveling crawler 2 (the left traveling crawler 2 in the present embodiment). , 22 can be smoothly slid along the longitudinal direction.

  Thus, after making the both lid cover bodies 103 and 104 into the open posture (see the solid line state in FIG. 9), the handle member 107 is pulled in a direction away from the other side wall 5b of the threshing device 5, thereby 103 and 104 are pulled out together from the lower part of the threshing device 5 in the direction opposite to the grain tank 7 (the left side of the traveling machine body 1 in this embodiment). Next, at a stage after the connecting guide shaft 122 passes the location of the restricting piece 125, the hand gripping the grip portion of the handle member 107 is further pushed down, and the cover members 103 and 104 are swung downward around the connecting guide shaft 122. By moving (turning), the lid cover bodies 103 and 104 are brought into a discharge posture that is inclined obliquely downward further than in the open posture (see the two-dot chain line state in FIG. 9).

  Residues placed on the lid cover bodies 103 and 104 are slid down or scraped along the lid cover bodies 103 and 104 to open outwardly opening ends 103a at one end portions of the lid cover bodies 103 and 104. , 104a (see FIG. 8) is discharged to the side of the threshing device 5 (in this embodiment, outside the other side wall 5b). In addition, what is necessary is just to follow the procedure contrary to the above, when returning both the lid cover bodies 103 and 104 from a discharge | release position (refer the dashed-two dotted line state of FIG. 9) to a closed position (refer FIGS. 5-7).

  According to the above structure, after collecting the residue which existed in each receptacle 21 and 22 on the upper surface (inner bottom surface) of each lid cover body 103 and 104, these lid cover bodies 103 and 104 are removed from the threshing device 5. Therefore, the residue can be easily collected and removed for each of the lid cover bodies 103 and 104 without being scattered under the threshing device 5. Therefore, it is possible to reduce the burden on the operator when cleaning the receiving rods 21 and 22, contributing to the efficiency of the cleaning work.

  Moreover, even if it has forgotten to return these lid cover bodies 103 and 104 to the original closed posture after pulling out both lid cover bodies 103 and 104 to the side of the threshing device 5, Since 104 is exposed in a state of protruding outward from the other side wall 5b of the threshing device 5, the operator can surely see both the lid cover bodies 103 and 104. That is, according to the configuration of the present embodiment, the operator can easily and quickly grasp the open / closed state of both lid cover bodies 103 and 104. Therefore, there is no possibility of forgetting to store both lid cover bodies 103 and 104.

  In the present embodiment, one end portions of the both lid cover bodies 103 and 104 are detachably connected to the threshing device 5 via the engaging means 105, while the other end portions of the both lid cover bodies 103 and 104 and the threshing are connected. When the connection between the one end portion of the both lid cover bodies 103 and 104 and the threshing device 5 is released between the device 5 and the device 5, the lid cover bodies 103 and 104 can be swung up and down around the other end portion and received. Since the guide support means 121 that is slidably supported along the longitudinal direction of the flanges 21 and 22 is provided, the guide cover means 121 allows the lid cover bodies 103 and 104 to swing up and down (rotate). The corresponding long holes 101 and 102 can be opened and closed, and residues can be collected together by sliding movement of the lid cover bodies 103 and 104 in the open posture. Therefore, when the configuration of the present embodiment is adopted, the opening and closing operation of the lid cover bodies 103 and 104 is easy and easy to handle, which contributes to the improvement of work efficiency when cleaning the receiving rods 21 and 22. .

  Further, in the present embodiment, one end portions of the lid cover bodies 103 and 104 are connected via the beam member 106, while the other end portions are connected via the connection guide shaft 122, and both ends of the connection guide shaft 122 are connected. Since the structure of hold | maintaining a part slidably with a pair of guide rails 123 and 123 provided in the lower surface of the threshing apparatus 5 is adopted, one end part of both the lid cover bodies 103 and 104 and the threshing apparatus 5 In a state where the connection with the other side wall 5b is released, the handle member 107 is pushed and pulled in the longitudinal direction (left and right lateral direction) of the receiving rods 21 and 22, thereby receiving the two lid cover bodies 103 and 104. Can be taken in and out along the longitudinal direction. Thereby, the trouble of taking in and out the two lid cover bodies 103 and 104 is reduced, and the working efficiency when cleaning the receiving rods 21 and 22 can be further improved.

  The configuration of each part in the present invention is not limited to the illustrated embodiment, and various modifications can be made without departing from the spirit of the present invention.
