As shown in fig. 4, the dewatering assembly comprises an extrusion cylinder 11 and an extrusion screw shaft 12, the extension direction of the extrusion cylinder 11 is the same as that of the feeding cylinder 9, the extrusion cylinder 11 also has a head end and a tail end, and the tail end of the extrusion cylinder 11 is detachably connected with the head end of the feeding cylinder 9. Specifically, the tail end of the extrusion barrel 11 is fixedly connected with the head end of the feeding barrel 9 through a bolt, a tail end barrel opening of the extrusion barrel 11 is communicated with a head end barrel opening of the feeding barrel 9, and materials in the feeding barrel 9 are conveyed into the extrusion barrel 11 through a feeding screw shaft 10.

And an extrusion screw shaft 12 is coaxially arranged in the extrusion container 11, the extrusion screw shaft 12 extends along the direction from the tail end to the head end of the extrusion container 11, and an extrusion channel for extruding materials is formed between the extrusion screw shaft 12 and the inner wall of the extrusion container 11. The head end of the extrusion container 11 is also provided with a discharge port 24, and the discharge port 24 is communicated with the extrusion channel. In the scheme, the extrusion screw shaft 12 comprises a rotating main shaft 13 and a helical blade 14, the helical blade 14 winds on the outer wall of the rotating main shaft 13, the diameter of the rotating main shaft 13 gradually increases along the direction from the tail end to the head end of the extrusion container 11, meanwhile, the tail end of the rotating main shaft 13 is connected with the head end of the feeding screw shaft 10, and the rotating motor 31 drives the rotating main shaft 13 to rotate synchronously when driving the feeding screw shaft 10 to rotate. When the rotating main shaft 13 rotates synchronously with the feeding screw shaft 10, the screw blades 14 on the rotating main shaft 13 drive the materials to move towards the discharge port 24. Meanwhile, as the diameter of the rotating main shaft 13 is gradually increased along the direction from the tail end to the head end of the extrusion container 11, the width of an extrusion channel between the screw shaft and the inner wall of the extrusion container 11 is gradually reduced, the pressure of the rotating main shaft 13 and the inner wall of the extrusion container 11 on the materials in the feeding process is gradually increased, the rotating main shaft 13 and the inner wall of the extrusion container 11 extrude and dehydrate the materials, and the dehydration effect of the materials is improved.

Meanwhile, a material pushing part and an elastic part are arranged at the discharge port 24. In a preferred embodiment, the material supporting member is an end cone 15, the end cone 15 extends along the length direction of the extrusion screw shaft 12, and the diameter of the end cone 15 gradually increases from the discharge port 24 toward the direction away from the discharge port 24.

A resilient member acts on the tip cone 15. Specifically, referring to fig. 4, the present embodiment further includes a connecting shaft 18, and the extending direction of the connecting shaft 18 is the same as the extending direction of the screw extruding shaft 12. The connecting shaft 18 penetrates through the tip cone 15, the tip cone 15 can slide along the connecting shaft 18, a limiting block 17 penetrates through the connecting shaft 18 and is in threaded connection with the limiting block 17, the elastic part is a spring 16, the spring 16 is sleeved on the connecting shaft 18, and two ends of the spring 16 are respectively abutted against the limiting block 17 and the tip cone 15.

When the extrusion screw shaft 12 drives the material in the extrusion channel to move towards the discharge port 24 until the material abuts against the tip cone 15, the material gives an acting force to the tip cone 15 to move away from the discharge port 24. The spring 16 will now give the tip cone 15 a force opposite to the direction of movement of the material so that the tip cone 15 presses the material in the extrusion channel. The material receives the spacing of tip cone 15 and piles up in discharge gate 24, it takes place to extrude further to realize the extrusion dehydration to pile up the material that comes on the material of discharge gate 24 and follow-up feeding, only when the material piles up to certain volume, the material just can extrude the tip cone 15 and force the tip cone 15 to do for discharge gate 24 and keep away from the action, the tip cone 15 slides along connecting axle 18 and forms the unloading passageway that is used for through the material and realizes the unloading, make the extrusion dehydration of material more abundant through the tip cone 15. And because the outer conical surface of the tip cone 15 is inclined relative to the inner wall of the extrusion container 11, the feeding path is greatly reduced in the process that the material collides with the surface of the tip cone 15, the extrusion pressure is increased, and the dehydration effect is improved.

And it is easy to understand, in the farm product rubbish, the water content of the farm product rubbish of melon and fruit class is big, and the water content of the coarse fiber farm product rubbish such as wheat straw, maize leaf is just little. The deformation amount of the spring 16 is adjusted by turning the limiting block 17, so that the acting force of the spring 16 on the tip cone 15 is adjusted. The larger the acting force of the spring 16 on the tip cone 15 is, the larger the force required by the material to push the tip cone 15 to form a blanking channel is, more materials are required to be stacked and extruded at the discharge hole 24, and the extrusion dehydration effect is better. To melon and fruit class farm trade rubbish, its water content is big, just turns round stopper 17 and makes the compression of spring 16, and then makes melon and fruit class farm trade rubbish extrusion more abundant. And to the farmer's rubbish of coarse fibre class, its water content is few, just reverse turn knob stopper 17 reduces the deformation volume of spring 16, and the material promotes tip cone 15 and forms the required power of unloading passageway just for little, when guaranteeing extrusion dehydration effect, can push away tip cone 15 faster and accelerate unloading speed.

The outer conical surface of the tip cone 15 is also provided with a multi-step 23 along the length direction thereof. When the material offsets with tip cone 15, the material bumps to step 23, and the material is more finely broken by extrusion, and the effect of extrusion dehydration is better.

When the material is conveyed to the discharge opening 24, part of the material is extruded into the discharge gap 22 while the material pushes away the tip cone 15. Because the tip cone 15 and the connecting shaft 18 rotate synchronously, the teeth 21 on the tip cone 15 rotate to extrude the material in the discharging gap 22, and an extrusion force of circumferential rotation is given to the material to further extrude and dewater the material. The steps 23 are provided on the outer wall of the teeth 21.

It should be noted that, in the embodiment, the cross section of the trepanning 20 of the sleeve 19 is a quadrangular structure with a chamfer, but the cross section may also be a triangular structure, a pentagonal structure, a hexagonal structure, or the like under the condition that the connecting shaft 18 can drive the tip cone 15 to rotate synchronously.

The vertical distance between the nozzle of the discharge pipe 30 at the bottom of the material collecting box 29 and the bottom end face of the cover body 1 is the height of the garbage bin. It will be readily appreciated that for ease of blanking, the mouth of the discharge duct 30 at the bottom of the bin 29 needs to be vertically spaced from the bottom end face of the housing 1 by the height of the bin. The height of the head end of the extrusion cylinder 11 is fixed, and if the extrusion cylinder 11 and the feeding cylinder 9 are horizontally arranged, the whole height of the cover body 1 needs to be very high in order to accommodate the crushing box 7 above the feeding cylinder 9. And a certain included angle is formed between the extrusion cylinder 11, the feeding cylinder 9, the feeding screw shaft 10 and the extrusion screw shaft 12 and the horizontal plane. The extrusion container 11 leaves a large amount of space in the vertical direction to accommodate the crushing box 7, and the height of the crushing box 7 is lower than that of the head end of the extrusion container 11, so that the overall height of the cover body 1 is reduced, and the material cost of the cover body 1 is saved.
