The front surface of the gear 3 16 is close to the outer wall of the fixed plate 23 and is provided with a slide groove 22 for facilitating the sliding of the round rod 19. The inner wall of the slide groove 22 is slidably connected with the supporting gear 3 16 and the round rod 19 of the box body 1. The rear surface of the round rod 19 is fixedly connected to the inner wall of the box body 1 near the right side of the supporting rod 17. The front end outer wall of the rotating rod 14 penetrates and is rotatably connected to the inner wall of the fixed plate 23. The inner wall of the fixed plate 23 is set to be hollow. The mutual cooperation between the gear 2 18, the gear 1 15 and the gear 3 16 enables the stirring paddle 20 and the cutting blade 21 to rotate in different directions, so that the stirring paddle 20 and the cutting blade 21 can be staggered to stir, mix and crush the soil, and the soil can be quickly crushed, thereby improving the crushing efficiency of the device and being more practical.
[0033] Reference Figure 1 , Figure 2 A feed box 2 is provided at the top of the box body 1 for easy entry of soil, a discharge box 5 is provided at the bottom of the box body 1 for easy discharge of soil, and a discharge port 9 is provided on the inner wall of the discharge box 5 for easy discharge of soil.
[0034] Reference Figure 3The bottom of the inner wall of the box body 1 is fixedly connected with one end of a spring 13, and the spring 13 is used to connect the sieve plate 11 and the box body 1. The top of the spring 13 is fixedly connected with the sieve plate 11 that can screen the soil. The right side of the inner wall of the box body 1 is provided with a limit groove 10 for facilitating the sieve plate 11 to slide up and down. The outer wall of the sieve plate 11 is slidably connected in the limit groove 10. The outer wall of the sieve plate 11 is convex, and the limit groove 10 is a T-shaped groove. The convex shape of the sieve plate 11 slides in the limit groove 10, so that the sieve plate 11 can shake up and down to screen the soil. The top of the sieve plate 11 is fixedly connected with a round block 12 connected to the sieve plate 11. The top of the round block 12 is set as an inclined surface. The round block 12 with the inclined surface is convenient for the stirring paddle 20 to hit and squeeze the round block 12. The stirring paddle 20 squeezes the round block 12 and the sieve plate 11, so that the sieve plate 11 is subjected to the tension of the spring 13, allowing the sieve plate 11 to slide up and down in the limiting groove 10, thereby realizing the up and down screening of the sieve plate 11, and better screening and collecting the soil.
[0035] Reference Figure 1 , Figure 2 The top of the box body 1 is fixedly connected with a base 7 supporting the box body 1 near the discharge box 5, and a discharge box 6 for collecting the screened soil is placed on the top of the base 7.

[0036] Working principle: Before use, put the discharge box 6 on the base 7, and put the soil from the feed box 2 into the box body 1. When in use, turn on the motor 8, and the motor 8 will drive the rotating rod 14 connected thereto to rotate, and the gear 1 15 connected to the rotating rod 14 will rotate accordingly, and the gear 2 18 and the gear 3 16 meshing with the gear 1 15 will be driven accordingly, thereby generating rotation. The gear 1 15 and the gear 3 16 are respectively located on the left and right of the gear 2 18. Therefore, the rotation directions of the gear 1 15 and the gear 3 16 are opposite, the gear 1 15 rotates clockwise, and the gear 3 16 rotates counterclockwise. When the gear 3 16 rotates, it will drive the stirring paddle 20 to rotate to stir the soil. When the rotating rod 14 rotates, it also drives the cutting blade 21 to rotate. , thereby cutting larger soil into small pieces. When the stirring paddle 20 rotates, it will hit the round block 12. The top of the round block 12 is an inclined surface. The stirring paddle 20 hits the inclined surface of the round block 12 and squeezes the round block 12. The sieve plate 11 will move downward. The stirring paddle 20 is in a rotating state, so the squeezing of the round block 12 is intermittent, and when the sieve plate 11 moves downward, it squeezes the spring 13 to generate a reaction force. Under the influence of the reaction force of the spring 13, the sieve plate 11 will reciprocate longitudinally, so that the sieve plate 11 can be shaken up and down to sieve the soil. The sieved soil will be sieved from the sieve plate 11 and fall into the discharge box 5, and then discharged from the discharge port 9 of the discharge box 5, and finally collected in the discharge box 6. After use, turn off the motor 8.
