The connecting rod 15 is enclosed to form a regular polygon hollow structure, namely, the driving shaft 4 is in non-surface contact with the conveying belt 6 through the connecting rod 15, so that the anti-slip effect is realized; hollow out construction can form an holding chamber in regular polygon's inside promptly, when partial domestic waste passed the conveyer belt through the hole of conveyer belt, can scrape into the holding intracavity through connecting rod 15 to the conveyer belt, the domestic waste that will permeate the coming scrapes, plays the effect of clearance conveyer belt, and the conveyer belt does not have of course to adhere to, and the extrusion effect also can ensure. And a support ring 25 is arranged in a regular polygon hollow structure surrounded by the connecting rod 15, and the support ring 25 is used for supporting the connecting rod 15. The gap distance between two adjacent connecting rods 15 is 3-5cm or 6-8 cm. The concrete can be determined according to the diameter of the circumscribed circle of the section of the actual driving shaft 4. In the application, the driving force required for driving the conveyer belt 6 is larger due to the weight of the conveyer belt 6, the weight of the conveyed garbage, the extrusion force born during extrusion and the like, so the used driving shaft 4 is thicker and can be selected from 6-8 cm. The infusion belt 22 is only used for conveying the extruded liquid and the entrained small particle solid, and the weight of the infusion belt is light, so the selected infusion driving shaft 24 can be 3-5 cm. The outer surface of the connecting rod 15 can be provided with anti-skid projections, so that the friction of the driving shaft 4 is further increased, and the special conveying requirements of water and oil containing of the household garbage and the like are better met.

Through the combined use of 1

home roll

8 and 2 bearing

rollers

9, 3 rollers constitute triangle-shaped, realize effective stable extrusion to domestic waste on the conveyer belt 6, and the liquid that extrudes flows out through the hole on the conveyer belt 6.

The main roller 8 comprises a roller shaft 10, a first roller 11 and a second roller 12, the roller shaft 10 is arranged at two ends of the first roller 11 respectively, the second roller 12 is sleeved on the outer circumference of the first roller 11, the second roller 12 is made of rubber, and the roller shaft 10 drives the first roller 11 and the second roller 12 to rotate simultaneously under the driving of a driving device. The first roller 11 and the second roller 12 are fixedly connected.

The rubber thickness of the second roller 12 is 40mm +/-5 mm. The optimization setting of 12 thickness of second roller to domestic waste's characteristics, realizes that the domestic waste after broken-screening can both effectually pass through every squeeze roll, and this thickness of rubber material can provide sufficient deflection to the squeeze roll when the extrusion, guarantees that the solid particle thing that meets can both pass through the squeeze roll. When the rubber material thickness of second roller 12 was too thick, the elastic deformation volume increase of rubber material can weaken relatively to the extrusion ability of liquid, and when the rubber material thickness of second roller 12 was too thin, the elastic deformation volume of rubber material was too little, and the granule that the solid matter is slightly bigger can't pass through smoothly again, or is detained before the squeeze roll always, or passes through the squeeze roll by force, but can cause the damage to domestic waste conveyer belt 6.

The circumferential surface of the second roller 12 is provided with a groove 18, and the groove 18 is used for the rapid passing of the household garbage during the initial extrusion.

8 and 2 carrier rollers 9) can be arranged, and multi-stage extrusion operation is realized. During the multi-stage extrusion operation, the opening depth of the groove 18 on the second roller 12 can be gradually reduced, so that the extrusion efficiency can be better improved. A drainage groove can be formed in the groove 18, so that the extruded liquid can be conveniently and quickly separated from the second roller 12.

And a rubber layer is sleeved on the outer circumference of the carrier roller 9. The supporting roller 9 mainly provides a supporting force for the main roller 8 and the conveying belt 6, and simultaneously guarantees the extrusion effect of the extrusion device.
