As the third lifting cylinder 803 is raised, the inlet gate of the mobile material collection box is raised to open the feed port.

[0026] In order to facilitate the limiting of the inlet gate of the mobile aggregate box, the front sides of the two vertical frames of the door-shaped frame 801 are respectively provided with guide grooves 11 for guiding and cooperating with the side edges of the door body of the gate of the mobile aggregate box receiving port.

[0030] The specific extrusion process of the integrated kitchen waste extrusion device of the present invention is as follows: the garbage is subjected to a first-level extrusion and drainage through the extrusion pusher head 2 in the extrusion bin 3. After reaching a certain extrusion force, the first lifting mechanism 6 lifts the first gate plate 4, and further pushes forward through the pushing action of the extrusion pusher head 2, further pushes and pushes the garbage to transcribe the space of the extrusion bin 3, and performs the next round of extrusion and drainage of the feeding garbage, and pushes forward again. The garbage is repeatedly extruded and pushed in sections for multiple times, so that a large amount of liquid in the garbage is squeezed out, and the volume of the garbage is greatly reduced. After the extruded garbage reaches a certain amount, the mobile collection box is docked to the outlet At the material inlet, the clamping mechanism is activated to clamp and connect the mobile material collection box and the discharge end of the extrusion bin, the third lifting mechanism is activated to open the gate of the mobile material receiving box, and the second lifting mechanism is activated to open the second gate to the maximum. At this time, the extrusion cylinder continues to squeeze and push the extrusion push head forward to push the extruded garbage material to the mobile material collection box until the material reaches the innermost part and the extrusion push head 2 cannot be further lifted and pushed. The extrusion cylinder retracts in the opposite direction and returns to the initial position to wait for the next round of feeding pre-extrusion. At the same time, the third lifting mechanism, the second lifting mechanism and the first lifting mechanism descend in turn to close each gate to complete a segmented pre-extrusion process. The aforementioned segmented pre-extrusion process can be repeated many times until the mobile material collection box is filled. The utility model uses the integrated kitchen waste extrusion device to perform multiple segmented pre-extrusions on the garbage to achieve compression and drainage of the garbage, transfer and push to the mobile material collection box, increase the net garbage load of the mobile material collection box, and reduce liquid dripping during transportation, reducing the impact of water on the surrounding environment.
