Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Examples

Referring to fig. 1, the present embodiment provides a feed grinder, which mainly includes: the machine comprises a machine shell 1, a crushing mechanism and a cleaning mechanism; the shell 1 is provided with a feed inlet 11 and a discharge outlet 12; the crushing mechanism comprises a rotating shaft 21 and a cutter 22, and the rotating shaft 21 is connected with a driving motor 23 in a transmission way. The cleaning mechanism includes a first fixing plate 31, a first cleaning brush 32, a second fixing plate 33, and a second cleaning brush 34. One end of the first fixing plate 31 is fixed to the inner wall of the housing 1, and the first cleaning brush 32 is fixed to the first fixing plate 31. One end of the second fixing plate 33 is fixed to the inner wall of the housing 1, and the second cleaning brush 34 is fixed to the second fixing plate 33. A gap 35 that matches the thickness of the cutter 22 (the dimension of the cutter 22 in the up-down direction shown in fig. 1) is left between the first cleaning brush 32 and the second cleaning brush 34.

Raw materials enter the machine shell 1 from the feeding hole 11, the driving motor 23 is used for driving the rotating shaft 21 and the cutter 22, the cutter 22 crushes the raw materials, and the crushed materials are discharged from the discharging hole 12. In the process that the cutter 22 rotates along with the rotating shaft 21, the cutter 22 can penetrate through the gap 35 between the first cleaning brush 32 and the second cleaning brush 34, and residues attached to the cutter 22 are swept by the first cleaning brush 32 and the second cleaning brush 34, so that the crushing effect on raw materials is ensured, and the waste of the raw materials is reduced.

A filter screen 4 is arranged between the cutter 22 and the discharge port 12, and only fine materials which can pass through the filtering holes of the filter screen 4 can be discharged from the discharge port 12, so that the coarse materials with larger volume are prevented from being mixed in the fine materials discharged from the discharge port 12.

The filter screen 4 is ring-shaped, a first connecting ring 41 is fixed on the inner side of the filter screen 4, a second connecting ring 42 is fixed on the outer side of the filter screen, the first connecting ring 41 is sleeved on the rotating shaft 21, and the second connecting ring 42 is abutted against the inner wall of the casing 1. First connecting ring 41 can be under elevating system's effect and make up and down reciprocating motion to make filter screen 4 do up and down reciprocating motion, this one side can make the material on the filter screen 4 leak down better, and on the other hand in the in-process that filter screen 4 reciprocated, the material that is located filter screen 4 top reciprocated along with filter screen 4 for rotation axis 21 reciprocates, in order to improve the crushing effect to the material.

Specifically, the lifting mechanism includes a guide plate 51, a top rod 52, a limit rod 53, and a driving rod 54.
