[0034] The convenient disassembly mechanism 9 includes:

[0035] Two first rotating rods 9-1, the two first rotating rods 9-1 are respectively rotatably arranged in the front and rear side walls of the mounting frame 2 through bearings. The two ends of the first rotating rod 9-1 are respectively rotatably arranged with second rotating rods 9-2 through bevel gear pairs.

[0038] When using the present utility model, start the motor 4. The motor 4 drives the rotating shaft 5 connected to its output shaft to rotate, and through the meshing of two gears 7, the synchronous reverse rotation of the two rotating shafts 5 is achieved. The rotating shaft 5 can drive the pressure roller 6 to rotate, and the two pressure rollers 6 can extrude the waste poured into the crushing box 1. The waste after extrusion will fall onto the guide plate 10. Among them, the water in the bottle-like solid waste will drip into the liquid storage tank 8 through the filter holes as the bottle-like solid waste is squeezed and broken. Affected by the inclined guiding of the guide plate 10, the waste falling above it will move towards the crushing assembly 3, and then the crushing assembly 3 will crush the waste.

[0039] When maintenance is required for the crushing assembly 3, the control handle 9-3 can be rotated. The control handle 9-3 drives the second rotating rod 9-2 on one side to rotate, and through the cooperation of the bevel gear pair, the first rotating rod 9-1 and the third rotating rod 9-4, the synchronous rotation of several second rotating rods 9-2 can be achieved. The second rotating rod 9-2 drives the limiting plate 9-5 to rotate, so that the limiting plate 9-5 completely rotates into the storage groove 11 and disengages from the limiting groove 12. The third rotating rod 9-4 drives the limiting cylinder 13 to rotate. During the rotation of the limiting cylinder 13, affected by the guiding of the guiding block 20 in the guiding groove 19, it moves towards the inner side of the cylindrical groove, so that the limiting cylinder 13 disengages from the connecting socket 14. After that, the mounting frame 2 can be pulled to the left to move the mounting frame 2 out of the crushing box 1, facilitating the maintenance of the crushing assembly 3 by the staff.

[0040] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0041] 1. Through the cooperation of the motor 4, the rotating shaft 5, the pressure roller 6, the gears 7, the liquid storage tank 8 and the guide plate 10, the waste can be extruded before crushing, which not only facilitates improving the crushing effect of subsequent crushing work, but also enables the liquid in the bottle-like solid waste to flow out and be collected.
