Arc-shaped grooves 817, which are used in conjunction with the secondary multi-faceted insertion posts 806, are formed on both sides of the front side and the rear side of the treatment bin 1, and the arc-shaped grooves 817 penetrate into the interior of the rectangular frame 802. A displacement frame 808 is fixedly connected to one side of the cross-shaped slide plate 801. A double beveled plate 809 with a handle, which is used in conjunction with the displacement frame 808, is fixedly connected to the bottom of the mounting frame 601; Installation columns 810 are rotatably arranged on the front side and the rear side of the processing bin 1. Second belt pulleys 811 are fixedly connected to the front side and the rear side of the surface of the installation column 810 and the right crushing shaft 2. A second belt 812 is drivingly connected between two second belt pulleys 811 in the same plane. Strip frames 813 are slidably arranged on the front side and the rear side of the processing bin 1.

[0027] Longitudinal cross chutes 12 which are slidably adapted to the cross slide plate 801 are formed on both sides of the processing bin 1.

Transverse sliding sleeves 14 which are slidably adapted to the transverse plates 13 are fixedly connected to both sides of the front side and the rear side of the processing bin 1.

[0028] The specific operation steps are as follows: Step 1: Intermittently and orderly feed and roughly crush soil blocks: Start the driving motor 4, so that the driving motor 4 meshes with the first gear 3 through the first gear 3, so that the two crushing shafts 2 rotate in opposite directions. The rotation of the crushing shaft 2 drives the camshaft 703 to rotate synchronously through the transmission cooperation of the first belt pulley 705 and the first belt 706. The camshaft 703 drives the second movable frame 702 and the feeding frame 701 to reciprocate. The reciprocating movement of the feeding frame 701 will intermittently feed the stored materials in the storage bin 5. When the feeding frame 701 moves, it will synchronously drive the soil-breaking cone 704 to reciprocate to roughly crush large soil blocks. During the reciprocating reset of the feeding frame 701 carrying the soil-breaking cone 704, the fitting socket 708 will, through the insertion cooperation with the insertion hole 707, clean the soil blocks stuck in the gaps between the blades of the soil-breaking cone 704. Step 2: Separate and crush soil blocks: When the soil material is fed from the bottom of the storage bin 5, the soil blocks fall on the tops of many inclined guiding plates 602. The finely crushed soil blocks fall through the gaps between the guiding plates 602 and finally fall into the inside of the sieve frame 804. The large soil blocks fall along the guiding track of the guiding plates 602 into the crushing gap between the two crushing shafts 2. After being crushed by the crushing shafts 2, the soil blocks successively fall into the inside of the sieve frame 804. While the crushing shaft 2 rotates, it drives the cam 606 to rotate simultaneously. The rotation of the cam 606 reciprocally drives the first movable frame 607 and the bending frame 608 to move up and down, prompting the mounting frame 601 to drive a plurality of material guiding inclined plates 602 to reciprocally vibrate up and down, accelerating the separation and discharging speed of large soil clods. When the material guiding inclined plates 602 reciprocally move up and down, the material guiding inclined plates 602 synchronously drive the extrusion plate 603 and the sliding rod 604 to move. When the sliding rod 604 moves upward, the sliding rod 604 slides and guides along the inclined hole inside the inclined hole seat 610, prompting the sliding rod 604 to drive the extrusion plate 603 to reciprocally move back and forth, so that the soil clods stuck in the gap between the material guiding inclined plates 602 can be reciprocally extruded by the extrusion plate 603, causing the local crushing of the soil clods and then smoothly falling into the inside of the sieve frame 804; Step 3: Sieving the crushed soil from multiple angles; When the mounting frame 601 drives the material guiding inclined plates 602 to reciprocally move up and down, the mounting frame 601 synchronously drives the double bevel extrusion plate 809 with a handle to extrude the displacement frame 808 up and down, prompting the displacement frame 808 to drive the cross-shaped sliding plate 801 and the rectangular frame 802 to reciprocally move back and forth, and the rectangular frame 802 drives the sieve frame 804 to reciprocally sieve back and forth; When the right crushing shaft 2 rotates, the right crushing shaft 2 synchronously drives the mounting column 810 to rotate through the transmission cooperation of the second pulley 811 and the second belt 812. The rotation of the mounting column 810 drives the eccentric rod 814 to move in a circle, and the eccentric rod 814 reciprocally drives the strip frame 813 to move left and right. The strip frame 813 drives the tooth plate 815 to reciprocally engage with the second gear 816, prompting the multi-sided inner socket 805 to drive the sieve frame 804 to reciprocally rotate left and right slightly to adjust the screening angle through the multi-sided insertion post 803.
