[0024] As a preferred implementation of this embodiment, the synchronous transmission unit includes a driving gear 12 fixedly sleeved on the driving shaft 7, and the bottom ends of the multiple crushing shafts 10 are fixedly mounted with driven gears 13 meshing with the driving gear 12. The advantage of this arrangement is that when the driving shaft 7 rotates, the driving gear 12 will be driven to rotate, and the rotation of the driving gear 12 will drive the multiple driven gears 13 to rotate together, thereby achieving the purpose of driving the multiple crushing shafts 10 to rotate synchronously.

[0025] As a preferred implementation of this embodiment, four supporting legs 14 are evenly fixedly installed at the bottom of the device base 2, and movable sleeves 15 are slidably sleeved on the four supporting legs 14. A connecting cross column 16 is fixedly installed on the sides of each two movable sleeves 15 close to each other.

When the movable wheel 17 is moved upward to be separated from the ground, the device can be stably placed on the ground. When the movable wheel 17 is moved downward to lift the device, the device can be directly pushed to move, which is labor-saving and convenient, and has better practicality.

[0026] In this embodiment, the lifting control assembly includes a control rotating rod 19 rotatably mounted on the inner wall of the side of the cavity, two vertical rotating holes are provided on the inner wall of the bottom of the cavity, and vertical studs 18 are rotatably mounted in the two vertical rotating holes, and two connecting cross columns 16 are respectively threadedly sleeved on the two vertical studs 18, one end of the control rotating rod 19 extends to the outside of the device base 2 and is fixedly mounted with a control dial 20, and a gear transmission unit for synchronously rotating the two vertical studs 18 is connected to the control rotating rod 19.

With the cooperation of the grinding ring 5, the rotation of the drive shaft 7 will drive multiple grinding rollers 9 to roll in a circle through the mounting frame 8 and the rotating shaft to grind the material. At the same time, the rotation of the drive shaft 7 will also drive multiple crushing shafts 10 to rotate synchronously through the driving gear 12 and the driven gear 13, and then drive multiple crushing blades 11 to rotate together to crush larger and heavier materials, so that all the input materials can be blown upward for grinding, thereby improving the crushing and grinding efficiency of the equipment and having good practicality.

[0032] When the device needs to be moved, the fixing pin 23 can be pulled upwards to move out of the fixing socket, the control dial 20 can be released, and then the control dial 20 can be turned. The rotation of the control dial 20 will drive the control lever 19 to rotate. The rotation of the control lever 19 will drive the two vertical studs 18 to rotate synchronously through the first bevel gear 21 and the second bevel gear 22. The rotation of the vertical studs 18 will drive the connecting cross column 16 to move up and down, and then drive the moving wheel 17 to move up and down together until the moving wheel 17 moves downward to lift the device. At this time, the device can be directly pushed to move. After moving to a suitable position, the control dial 20 can be rotated in the opposite direction to make the moving wheel 17 move upward to separate from the ground, and the device can be stably placed on the ground. Finally, take the fixing pin 23 and insert it into the fixing socket to fix the control dial 20.
