Description of the Related Art Conventionally, as a dropper structure of a combine, a straw for threshing process discharged backward from a transport end of a waste straw transporting device is received and supported by a waste straw receiving device, and the drainage is carried out. It is well-known that when a predetermined amount of straw is accumulated, the discharged straw receiver automatically swings downward, thereby discharging the discharged straw collectively to the ground, and then automatically returning to the discharged straw receiving position. In the above-mentioned conventional structure, a shaft along the up-down direction for restricting the discharged straw discharged from the discharged straw transporting device from protruding from the free end of the discharged straw receiving device is provided with a discharging straw transporting device. Is connected and supported in a suspended state at the rear end of an arm member continuously extended in a rearward state of the case for storing the arm member.

制ガイド棒が外方に突出しないようにする。(Operation) According to the structure of the first aspect of the present invention, the rear end of the case for accommodating the waste straw transporting device can be freely opened and closed, and the maintenance of the waste straw transporting device and the like can be performed. In the case of a dropper operation for discharging a predetermined amount of straw by a predetermined amount, a lid for opening and closing the rear end of the case is swung to an open position, and a regulating guide rod is suspended from the lid and supported. In this case, the use posture is such that the straw is prevented from dropping out of the free end of the straw receiver. On the other hand, when the dropper operation is not performed, the rear end of the case is closed with the lid. So that it does not protrude.

In addition, when the dropper work is not performed, the control guide rod can keep the lid aside and close the lid to prevent it from protruding outward. Since the members protruding rearward from the case can be eliminated, the longitudinal length of the body can be shortened, and the problem of the lid or the like coming into contact with other objects when traveling on a road or the like can be avoided. Further, since the lid is pivotally opened and closed, switching to the dropper working state can be easily performed.

More specifically, the waste straw processing unit transfers the waste straw after threshing by a threshing device (not shown) from the feed chain 2 to the waste straw transport chain 3 as a waste straw transport device, and transports the waste straw to the rear of the machine. I am trying to do it. The transported waste stirrer can be switched between a state where it is discharged from the waste straw transporting chain 3 to the waste straw shredding device 4 and a state where it is discharged to the dropper device 5 behind the waste straw shredding device 4. It is composed. That is, by changing the rear end position of the holding rail 3a in the waste straw transporting chain 3 back and forth, it is possible to freely switch between a state of being discharged to the waste straw shredding device and a state of being discharged to the dropper device 5. Make up.

ることが簡易に行える。[0009] The dropper device 5 includes a discharge straw transport chain 3.
Is installed at the rear end of the case 6 in which is stored. More specifically, a waste straw receiver 7 made of a sheet metal is supported on the lower side of the case 6 so as to be swingable around the horizontal axis P1. Then, a rear wall portion of the case 6, which is behind the straw distributing and transporting chain 3, of the case 6 covering the discharging straw and distributing chain 3 is supported so as to be swingable around the horizontal axis P2 to form a lid 8. I have. The lid 8 can be fixedly held in a posture in which the rear part of the case 6 is opened and a posture in which it is closed by a posture holder 9. And at the free end of the lid 8,
One end of a pair of left and right metal regulating guide rods 10 is pivotably supported. That is, as shown in FIGS. 1 to 3, the left and right side edges and the lower edge 8 a of the lid 8 have a flange structure that extends forward in a closed state, and the lower edge 8 a has friction. The pair of left and right regulating guide rods 10, 10 are cantilevered so as to be swingable left and right in a held state and can be held in an appropriate posture. These regulating guide rods 10 can be suspended from the lower edge 8a of the lid 8 while the lid 8 is held in the open position. In the suspended state, the lower end portions of the regulating guide rods 10, 10 are engaged with a pair of left and right locking grooves 11, 11 formed on the rear end edge of the discharge straw receiving member 7 in the receiving position, and receive the discharge straw. The stirrer supplied to the tool 7 is regulated so as not to fall backward, and is guided so as to be placed on the stirrer receiver 7. A link rod 12 is erected between the two regulating guide rods 10 so as to be relatively swingable.
Since each of the first and second control rods 0 and 10 is swingable in an interlocking manner, the rocking operation is performed by holding one of the regulating guide rods 10 or the link rods 12 so that the locking groove is formed as shown by a two-dot chain line in FIG. 1
The two restriction guide rods 10, 10 which have been released from being locked to the rods 1, 11
2 can be easily switched between a state in which both enter into the lid 8 and a state in which the cantilever is in a suspended posture as shown by a solid line in FIG.

受け具7は元の受け止め姿勢へ復帰して、待機する。The discharge straw receiving member 7 is supported between the case 6 by a biasing mechanism (not shown), and a load acting on the biasing mechanism due to the accumulation of the discharge straw on the discharge straw receiving member 7 is fixed. As a result of the above, the waste straw receiver 7
The receiving position of the lock is released, and the waste straw receiver 7 is moved to the horizontal axis P1.
It swings downward around, thereby discharging the waste straw from the waste straw receiver 7 downward. The discharge straw receiving member 7 returns to the original receiving posture by the return urging action of the urging mechanism in which the discharge straw load is released by the release, and stands by.

0 and 10 are oscillated in a suspended position, and the
Are locked in the locking grooves 11, 11. When the dropper device 5 is not used, the lid 8 is closed, and the drain stirrup receiver 7 is swung and held so that the case 6 is moved aside.
