It is used to drive the crushing cage connecting seat 11 to rotate through the driving motor 2, and then drive the central crushing cage 6 to rotate. At this time, the main shell 1 and the central axis 7 are both fixed, and only the central crushing cage 6 rotates. The large-diameter soil particles in the central crushing cage 6 are broken up by the central axis breaking roller 13, and pass through the curved screen wall of the central crushing cage 6 and fall onto the bottom screen 8. The soil particles are broken up again by the crushing cage breaking roller 10 on the central crushing cage 6, and the broken soil particles pass through the bottom screen 8 and fall into the discharging area 9, and are discharged from the discharging port 5.

[0029] The porosity of the curved screen wall of the central crushing cage 6 is greater than the porosity of the bottom screen 8, which is used to prevent large-diameter soil particles that fall into the bottom screen 8 from being directly discharged without being crushed, thereby improving the crushing effect of the soil particles.

[0030] The distance from the end of the crushing cage crushing roller 10 to the upper wall of the main body shell 1 is equal to the distance from the crushing cage crushing roller 10 to the bottom screen 8, which is used to improve the crushing effect.

[0035] The base frame 3 includes a bottom plate and at least two annular brackets 301. The annular brackets 301 are used to support the main housing 1. The two ends of the annular brackets 301 are connected to the bottom plate through columns. Universal wheels can be provided at the four corners of the bottom of the bottom plate for easy movement. The annular brackets 301 can be fixed on the main housing 1 to improve stability.

[0036] The feeding port 4 can be arranged at the opening of the central crushing cage 6 below the central axis 7 .

[0037] Working principle:

[0038] Soil particles with large diameter are put into the central crushing cage 6 from the feeding port 4, the feeding port 4 is closed, and the driving motor 2 is turned on. The connecting seat shaft 12 is driven by the driving motor 2 to rotate, and then the crushing cage connecting seat 11 and the central crushing cage 6 are driven to rotate. The crushing cage crushing roller 10 is driven to rotate during the rotation of the central crushing cage 6. When the central crushing cage 6 rotates, the soil particles are crushed once by the collision with the central axis crushing roller 13. The crushed small-diameter soil particles pass through the curved screen wall of the central crushing cage 6 and fall into the bottom screen 8. Since the holes of the bottom screen 8 are small, the soil particles cannot be screened, and are crushed again by the crushing cage crushing roller 10. The crushed soil particles fall into the discharging area 9 and can be discharged through the discharging port 5, completing the crushing and screening of the soil particles.

[0039] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art of the utility model may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
