[0002] With the development of my country's economy, more and more domestic garbage is generated in rural areas. However, if the traditional landfill method is used to dispose of rural garbage, a large amount of land will be occupied. In addition, there are a large number of industrial inserts containing harmful substances in the existing domestic garbage, and direct landfilling is likely to pollute the soil and water sources. Therefore, some rural garbage needs to be sent to the garbage incineration plant for incineration. In order to facilitate the incineration of garbage, a crushing mechanism is often needed to crush the garbage;

[0033] When the device is in use, the garbage to be crushed is placed on the right side of the partition 2, and the two crushing rollers 3 are driven to rotate by the dual-axis motor 7, and then the garbage is preliminarily crushed. Then, the completely crushed garbage is filtered through the filter plate 23 and stacked under the crushing box 1. The incompletely crushed garbage above the filter plate 23 enters the spiral feeding device 26 through the discharge port 24 and is transported to the inside of the feed box 38, and then falls between the two crushing rollers 4 for secondary crushing, thereby achieving the effect of cyclic crushing and ensuring a good garbage crushing effect.

[0034] like Figure 3 , Figure 7 and Fig. 9 As shown, a circular ring 8 is fixedly connected to the left side of the bracket 6, and a plurality of cavities 9 are opened inside the circular ring 8. A piston block 10 is slidably connected inside the cavity 9. An abutment column 11 is fixedly connected to the outer wall of the piston block 10.

[0038] like Figure 2 , Figure 4 and Fig.10 As shown, the left side of the partition 2 and the left side of the crushing box 1 are both rotatably connected to the guide plate 27 through a rotating shaft, a connecting rod 28 is arranged between the two guide plates 27, and both ends of the connecting rod 28 are rotatably connected to the rotating block 1 29 through a rotating shaft, and the outer side walls of the two rotating blocks 1 29 are respectively fixedly connected to the outer side walls of the two guide plates 27, and the left side of the partition 2 and the right side of the inside of the crushing box 1 are fixedly connected to a plurality of springs 30, and the right end of the spring 30 is fixedly connected to the lower surface of the guide plate 27, and the right end of the central axis of the crushing roller 24 located in the front of the crushing box 1 is fixedly connected to the gear 31.

A rotating block 2 36 is fixedly connected to the lower surface of the guide plate 27 on the right side of the crushing box 1. A pressure bar 37 is rotatably connected to the outer side wall of the rotating block 26 through a rotating shaft. The right end of the pressure bar 37 passes through the right side of the crushing box 1 and contacts the left side of the wedge-shaped head 34.

[0039] The rotation of the crushing roller 2 4 will drive the gear 3 31 to rotate together, so that the gear 3 31 engages with the top of the extrusion rod 33, driving the extrusion rod 33 to move up and down repeatedly, so that the wedge-shaped head 34 provided in cooperation can push the compressed horizontal bar 37 to move left and right repeatedly, and then can drive the guide plate 27 to move, which is convenient for guiding materials and avoids the problem of garbage accumulation.
