The fixed column 8 and the second fixed column 11 move. The upper surfaces of the two second fixed columns 11 are respectively fixedly connected to the first motor 12 and the second motor 15. The first motor 12 and the second motor 15 are fixedly connected to the first rotating shaft 13 and the second rotating shaft 16 respectively, which drive the first rotating shaft 13 and the second rotating shaft 16 to rotate. The side surfaces of the first rotating shaft 13 and the second rotating shaft 16 are respectively fixedly connected to the first blade 14 and the second blade 17. The first blade 14 and the second blade 17 are located in the slot and are staggered in the vertical direction, which facilitates uniform crushing of bio-fertilizer and makes the crushing effect better.

[0022] The upper surface of the partition 9 and the lower inner surface of the housing 1 are both fixedly connected to rails 21. The rails 21 are T-shaped to prevent the first fixed post 8 and the second fixed post 11 from detaching from the rails 21. Both the first fixed post 8 and the second fixed post 11 are provided with sliding grooves, allowing them to slide smoothly along the rails 21 for easy movement. Limiting blocks 20 are fixedly connected to both the upper surface of the partition 9 and the lower inner surface of the housing 1. The limiting blocks 20 are located outside the rails 21 and on the side of the first fixed post 8 and the second fixed post 11 closest to the crushing cylinder 19. The box 1 is rotatably connected to a first rotating column 4, and a first rotating door 2 is fixedly connected to the side surface of the first rotating column 4, which drives the first rotating door 2 to rotate. The box 1 is rotatably connected to a second rotating column 5, and a second rotating door 3 is fixedly connected to the side surface of the second rotating column 5, which facilitates the rotation of the second rotating door 3. The height of the first rotating door 2 is the same as the height between the partition 9 and the top of the box 1, which facilitates the isolation of the blade from the outside world. A collection box 18 is set inside the box 1. The collection box 18 is located behind the second rotating door 3. The position of the collection box 18 is determined to collect the bio-fertilizer.

[0023] Working principle: During use, bio-fertilizer is poured into the feed hopper 6. The first motor 12 and the second motor 15 drive the first rotating shaft 13 and the second rotating shaft 16 to rotate, thereby causing the first blade 14 and the second blade 17 to rotate and crush the bio-fertilizer. At the same time, as needed, the first hydraulic cylinder 7 and the second hydraulic cylinder 10 can drive the first fixed column 8 and the second fixed column 11 to adjust the position of the first blade 14 and the second blade 17, so as to adjust the crushing effect to a certain extent. The track 21 is designed to facilitate the sliding of the first fixed column 8 and the second fixed column 11. The limiting block 20 restricts the movement area of ​​the first fixed column 8 and the second fixed column 11. The crushed bio-fertilizer falls into the collection box 18 and can be taken out by opening the second rotating door 3. When it is necessary to maintain or replace the components inside the box, the first rotating door 2 can be opened.
