When the posture change operation body 45 is lowered from the lowering operation start position (e) to the lowering operation end position (f), the posture of the hook 68 is changed from the locking posture (c) to the locking release posture (d). I am doing so.

  Further, as shown in FIGS. 8 to 10, a temporary fixing body 78 for temporarily fixing the posture changing operation body 45 at the lowering operation end position (f) is attached to the rear upper part of the rear extension connecting plate 66 with an attachment bolt 119. Is attached through. In other words, the temporary fixing body 78 is integrally formed by a leaf spring with a horizontally long mounting piece 120 in the front-rear direction and a hanging piece 121 that hangs downward from the lower end central portion of the mounting piece 120. Then, as shown in FIG. 10 (b), the drooping piece 121 extends downward from the upper end portion 122 to the lower right side so as to form a downward inclined portion 80, and substantially extends from the lower end of the downward inclined portion 80 to the left side. A temporary fastening portion 81 is formed by extending horizontally, and a release operation portion 83 is formed by extending downward from the temporary fastening portion 81. Here, the downward inclined portion 80 has a lower end portion disposed at a position where the operation main piece 76 of the posture changing operation body 45 intersects with the vertical movement surface, and the temporary fixing portion 81 is in the downward operation start position (e). The change operation body 45 is disposed so as to be in contact with the upper end surface of the operation main piece 76, and the release operation portion 83 is disposed at a position immediately behind the rear end surface of the rear extension connecting plate 66.

  When the posture changing operation body 45 is lowered from the lowering operation start position (e) to the lowering operation end position (f) in this way, as shown in FIG. The lower end portion of the descending inclined portion 80 of the temporary fixing body 78 is pressed to 76 from above, and is displaced to the left by a minute width d. That is, the temporary fixing body 78 is deformed. Then, when the posture changing operation body 45 is lowered to the lowering operation end position (f), the temporary fixing body 78 is restored, and the temporary fixing portion 81 of the temporary fixing body 78 is operated by the operation piece of the posture changing operation body 45. It is arranged in a crossing shape directly above 76. That is, the operation main piece 76 of the posture changing operation body 45 is in a temporarily fixed state in which it is locked to the temporary fixing portion 81 of the temporary fixing body 78. As a result, the posture changing operation body 45 that is indirectly biased upward by the locking spring 70 is prevented from returning to the lowering operation start position (e). Further, when releasing the temporarily fixed state, the release operating portion 83 of the temporary fixed body 78 is pressed to the left side, and the lower end portion of the downward inclined portion 80 is displaced to the left side indicated by the arrow by a minute width d. As a result, the operation main piece 76 of the posture changing operation body 45 is temporarily released, and the posture changing operation body 45 that is indirectly urged to rotate upward by the locking spring 70 is moved to the lowering operation start position. Return to (e).

  Further, as shown in FIGS. 8 to 10, a round bar-like return operation lever extending in the front-rear direction is formed at a corner formed by the upper end surface of the laterally extending connecting plate 63 and the right side surface of the backward extending connecting plate 66. The front end portion of 84 is continuously provided so that the return operation lever 84 protrudes rearward substantially horizontally. When returning the waste transporting device 17 whose posture has been changed from the waste transporting posture (a) to the waste clogging releasing posture (b) to the waste transporting posture (a), By grasping the end portion and performing a lowering operation, the engagement recess 71 of the rearward extending connecting plate 66 is engaged with the lock pin 67 from above. Here, the return operation lever 84 has a shorter front-rear width than the posture change operation body 45. Since the posture changing operation body 45 needs to be operated in a state in which the waste transporting device 17 is clogged with waste, the posture changing operation body 45 is formed with a relatively long width to ensure good operability. On the other hand, since the return operating lever 84 is operated after removing the waste trapped in the waste transporting device 17, it is formed with a relatively short width to reduce weight and size.

  As described above, the waste transporting device 17 operates the posture changing operation body 45 from the rear of the machine body via the posture changing mechanism 60, so that the waste transporting posture (a) and the waste clogging release posture (b) are obtained. The posture can be changed. The posture changing operation procedure will be described below.

[Operation procedure from the waste transporting posture (a) to the waste clogging releasing posture (b)]
First, when the grip 75 of the posture changing operation body 45 is grasped and the operation piece 76 is lowered from the lowering operation start position (e) to the lowering operation end position (f), the hook 68 is engaged from the locking posture (c). The posture is changed to the stop release posture (d). Then, since the waste transporting device 17 is elastically biased upward by the tension spring 64, the waste transporting device 17 is swung (rotated) about the rotation axis P, and the waste transporting posture (a) is removed from the waste transporting posture (a). The posture is changed to (b). Therefore, the waste that is stuck in the waste transporting device 17 can be easily taken out. At this time, the operation main piece 76 of the posture changing operation body 45 is in a temporarily fixed state locked to the temporary fixing portion 81 of the temporary fixing body 78 and holds the hook 68 in the unlocking posture (d).

[Operation procedure from the waste clogging release posture (b) to the waste transporting posture (a)]
First, the release operation part 83 of the temporary fixing body 78 is pressed to the left side, and the operation piece 76 of the posture changing operation body 45 is set to the temporary fixed release state. Then, by gripping and lowering the rear end portion of the return operation lever 84, the engagement recess 71 of the rearward extending connecting plate 66 is engaged with the lock pin 67 from above. Then, the lower end portion 116 of the rear half of the hook 68 that is urged to swing backward slides on the outer peripheral surface of the lock pin 67, while the hook 68 moves forward (see FIG. 9) against the elastic urging force of the locking spring 70. The hook 68 is moved backward (counterclockwise in the side view of FIG. 9) by the elastic biasing force of the locking spring 70 when the engaging recess 74 is aligned with the lock pin 67. The engaging recess 74 is engaged with the lock pin 67 by swinging. That is, the hook 68 is in the locking posture (c). As a result, the evacuation / conveyance device 17 is changed from the evacuation / clogging release posture (b) to the evacuation / conveyance posture (a) and held in the evacuation / conveyance posture (a). At this time, the posture changing operation body 45 is returned to the lowering operation start position (e). For this reason, it is possible to quickly perform an operation for changing the posture of the waste transporting device 17 again from the waste transporting posture (a) to the waste clogging release posture (b).
