In this arrangement, the hook plate 10 is engaged with the valley surface 12 and the presser plate 13 is superposed on the upper side. At the next unlocked position 19, the cam surface XY moves to the position b as described above, and at the same time as the front end of the hook plate 10 comes into contact with the starting point X, the presser plate 13 is moved to the hook plate 10. It is arranged so as to deviate from the rear end. Further, at the extended position 17 where the cam surface XY has moved to the c position, the lever plate is arranged such that the hook plate 10 has passed the apex Y of the cam surface and the upward movement of the carrier A has been completed.
[0014]
2 and FIG. 3, the mounting of the lifting device will be described with reference to FIG. 2 and FIG. 3. A bearing 46 is provided on the reinforcing pipe 47 spanned on the rear frame 7, and the rotating lever 16 is fixed to the upper shaft end through which the vertical axis 15 is inserted. Then, the lifting cam 11 is fitted to the lower side and engaged with the hook plate 10, and the presser plate 13 that clamps the lifting cam 11 is fixed to the arrangement for superposition, and set bolts 57 are provided at the upper and lower shaft ends. It is a mounting structure in which the vertical axis 15 is rotatably mounted, and is configured such that the transport body A moves up and down by a lever operation in the direction of arrow A, and the transport state during the downward movement can be locked.
[0015]
FIG. 5 is a side view in which the transport body is moved upward, and the lifting device 8 is transported in conjunction with the operation of the rotation lever 16 in the transport state in which the waste chain 3 approaches the waste guide rod 21. A state in which A is moved upward and the guide body 5 guides the rejection chain 3 to the extended position of the expansion angle θ with respect to the rejection guide rod 21 is shown by a chain line. This is a waste transporting device in which both the guide body 5 and the lifting device 8 that move up and down are provided in front of and behind the reinforcing pipe 47 so as to correctly guide the waste chain 3.
[0016]
FIG. 8 is a cross-sectional front view of the fulcrum PP, in which a support shaft 36 is inserted into a metal 37 suspended from the rear frame 7, and a chain base 35 around which the exhaust chain 3 is wound is screwed. The roller 26 provided at the end of the conveyor belt 25 is rotatably mounted on the right side of the conveyor belt 25 so that the fulcrum PP of the conveyor A is formed behind the evacuation chamber 6. Further, on the working side for obliquely conveying the waste, the waste guide rod 21 and the head guide rod 27 are arranged side by side, and are transported while sandwiching the head side and the heel side. The evacuation guide bar 21 is supported by a spring 28 provided on the lower surface 55 and is lowered in the direction of the arrow C in accordance with the transport amount.
