[0038] like Figure 5 As shown, the dumping movement mechanism includes a U-shaped driving side plate 14 and a dumping bucket 15 arranged between the driving side plates 14; the driving side plates 14 are relatively arranged inside the transfer bin 6, and the dumping screw 16 is rotatably matched with the driving side plates 14 through bearings; a dumping motor 18 is fixed to the outer side of the transfer bin 6 through a motor bracket, and the dumping screw 16 extends out of the driving side plate 14, and the transfer bin 6 and the motor shaft of the dumping motor 18 are fixed through a coupling; a broken line dumping groove 17 is opened on the driving side plate 14, and the dumping groove 17 includes a left section, a middle section and a right section, and the left section, the middle section and the right section are parallel, and the dumping groove 17 runs through the driving side plate 14; as shown Figure 6 As shown, the dumping screw 16 is threadedly engaged with a linkage drive block 19, and the linkage drive block 19 is rotatably engaged with a dumping shaft 20, and a dumping ear plate 21 is fixed to the outer side of the dumping shaft 20 (the dumping shaft 20 and the dumping ear plate 21 will not rotate relative to each other); a linkage guide wheel 22 is rotatably set at the end of the dumping ear plate 21, and the linkage guide wheel 22 is engaged in the dumping groove 17; the inner side of the dumping shaft 20 is connected to the dumping bucket 15.

[0040] The material inside the dumping bucket 15 may be stuck to the inside of the dumping bucket 15 and cannot fall off. In order to solve this problem, Figure 8 As shown, the inner side of the tipping shaft 20 is connected to the tipping bucket 15 through a floating mechanism; the floating mechanism includes a floating plate 23 and a floating shaft 24 that is slidably fitted at both ends of the floating plate 23, and the inner side of the tipping shaft 20 is connected to the middle of the floating plate 23; the rotation of the tipping shaft 20 can drive the floating plate 23 to rotate, the inner side of the floating shaft 24 is fixed to the side of the tipping bucket 15, and the outer end of the floating shaft 24 is provided with an anti-slip shaft plate 25; a floating spring 26 is passed through the floating shaft 24, and both sides of the floating spring 26 are clamped between the anti-slip shaft plate 25 and the floating plate 23; a floating guide wheel 27 is provided on the outer side of the anti-slip shaft plate 25 on one side; Figure 8-9 As shown, a floating chute 28 corresponding to the floating guide wheel 27 is provided on the inner side of the driving side plate 14. The floating chute 28 is a U-shaped structure, and a floating protrusion 29 with a semicircular cross-section is provided inside the floating chute 28. When in use, when the dumping bucket 15 moves to the inside of the transfer bin 6 and the opening of the dumping bucket 15 faces downward, the floating guide wheel 27 rolls and fits in the floating chute 28, and the dumping bucket 15 continues to move deeper into the transfer bin 6. The floating protrusion 29 laterally squeezes the floating guide wheel 27, causing the dumping bucket 15 to swing laterally, thereby assisting in completely dumping the material inside the dumping bucket 15.

[0041] like Figure 10-11 As shown, a downward pressure mechanism is provided on the top of the transfer bin 6, and transverse pressure chambers 30 are provided at both ends of the lower side of the transfer bin 6. The transverse pressure chamber 30 is located on the upper side of the support platform 5 and is connected to the inside of the transfer bin 6. A transverse pressure cylinder 31 is provided on the side wall of the transverse pressure chamber 30.

A semicircular groove is provided on the inner side of the transverse pressure block 32, and a plurality of pressing protrusions 33 are provided on the side wall of the semicircular groove; a mesh plate 34 is provided at the bottom of the transfer bin 6, and a liquid collecting tank 35 is provided at the lower part of the transfer bin 6, and the liquid collecting tank 35 is connected to the bottom of the transfer bin 6 ; The liquid collecting tank 35 is connected to the liquid waste treatment system through a discharge pipe; in a natural state, the cross-pressure block 32 will be located inside the cross-pressure chamber 30; when the waste is transported to the bottom of the transfer bin 6, the cross-pressure cylinder 31 extends, and the two cross-pressure blocks 32 are relatively close to each other, squeezing most of the waste into the semicircular grooves; the two semicircular grooves form a groove with a circular cross-section; the downward pressure mechanism squeezes the waste surrounded by the two semicircular grooves downward to separate dry and wet waste; liquid waste enters the liquid collecting tank 35 through the mesh plate 34; the liquid waste is pumped to the liquid waste treatment system through the discharge pipe for treatment.

[0042] like Figure 12-13As shown, the pressing mechanism includes a pressing cylinder 36 and a pressing base frame 37 of a U-shaped structure. The pressing cylinder 36 is arranged on the top of the transfer bin 6, and the push head of the pressing cylinder 36 extends downward to the inside of the transfer bin 6 and is fixed to the adapter 38; the lower side of the adapter 38 is a shrinking groove structure, and the bottom of the shrinking groove is provided with a ball groove 39 with a circular cross-section, and a plurality of balls are rollingly matched in the ball groove 39; the two side ends of the pressing base frame 37 are provided with a downward sliding column 40, and the downward sliding column 40 is slidably matched with the top of the transfer bin 6, and the end of the downward sliding column 40 has an anti-slip structure; a rotating sleeve 41 is provided in the middle position of the pressing base frame 37, and the rotating sleeve 41 is a ring cavity structure; The side wall of the rotating sleeve 41 is provided with a zigzag guide groove 42, and the rotating rod 43 is slidably fitted in the rotating sleeve 41.

[0043] The two horizontal pressure blocks 32 are relatively close to each other, squeezing the waste into the semicircular groove, and the downward pressure cylinder 36 is extended. Under the action of the rotating rod spring 48, the downward pressure base 37 and the pressure plate 46 move downward at the same time; when the anti-slip structure at the end of the lower slide column 40 contacts the top of the transfer bin 6, the downward pressure base 37 will not continue to move downward, and the pressure plate 46 moves to the position corresponding to the horizontal pressure block 32; the downward pressure cylinder 36 continues to extend, driving the rotating rod 43 to slide downward along the rotating sleeve 41, and the guide protrusion 44 moves along the guide groove 42, thereby driving the rotating rod 43 to rotate relative to the rotating sleeve 41, and finally making the pressure plate 46 rotate ninety degrees when moving downward; thereby, the rotating plate is pressed down while twisting and squeezing the waste; compared with the direct squeezing method of the cylinder and the pressure plate 46, the separation effect is further improved.

[0044] The pushing unit is used to push the material at the bottom of the transfer bin 6 from the transfer bin 6 to the fireproof bin 9. Fig.14 As shown, one embodiment of the pushing unit includes a pushing cylinder 49 and a pushing plate 50. The pushing cylinder 49 is arranged at the bottom of the transfer bin 6. The pushing head of the pushing cylinder 49 extends inside the transfer bin 6 and is fixed to the pushing plate 50. The mesh of the mesh plate 34 is easily blocked by waste, thereby losing the separation effect. In order to solve this problem; Fig.15 As shown, another embodiment of the push unit includes a push cylinder 49 and a push cavity 51. The push cylinder 49 is arranged at the bottom of the transfer bin 6. The push head of the push cylinder 49 extends inside the transfer bin 6 and is fixed to the knocking drive plate 52.
