[0022] according to Figure 1 , 2As shown: the cylinder 1 3 is arranged on the outside of the housing 1, and the side wall of the cylinder shaft bed housing 1 is connected to the lower part of the crushing block 4, the gap between the crushing block 4 and the lower part of the triangular block 2 is gradually reduced, the upper part of the crushing block 4 is flush with the upper part of the housing 1, and the upper ends of the guide blocks 5 are located on both sides of the crushing block 4 and are flat; in this way, by changing the cylinder shaft length of the cylinder 1 3, the gap between the crushing block 4 and the triangular block 2 can be changed, so that the larger raw materials can be squeezed smaller;

[0023] according to Figure 4 As shown: there is a gap between the upper grinding block 6 and the lower grinding block 7, and the gap gradually decreases from top to bottom; this allows the device to gradually grind smaller distances when in operation;

[0024] according to Figure 2 As shown: the filter screen 10 and the guide plate 11 have different inclination directions, a vibrator is provided below the filter screen 10, and the guide plate 11 is provided with baffles on the outer side of the housing 1 for placing the raw materials flowing out from both sides; the filter screen 10 and the guide plate 11 are respectively installed on the output shaft of the motor 8 through bearings, so that when the motor 8 is started, the filter screen 10 and the guide plate 11 will not be driven to rotate, and the raw materials that do not meet the conditions and the raw materials that meet the conditions can flow out from the outlet at the lower end of the filter screen 10 and the outlet at the lower end of the guide plate 11, respectively, so that different treatments can be performed;

[0025] according to Figure 2 As shown: T-shaped plates 13 are provided on both sides of the opening of the outer shell 1 at the lower end of the filter screen 10, and a support plate 14 is provided at the lower end of the T-shaped plate 13.

[0026] The principle of the utility model is as follows: when in use, the raw material is first poured from the upper end of the shell 1 onto the crushing block 4, then the motor 8 and the vibrator are started, and the cylinder shaft of the cylinder 3 is continuously extended and shortened, the cylinder shaft of the cylinder 3 will drive the crushing block 4 to move back and forth, thereby changing the size of the gap between the triangular block 2, and then squeezing all the larger raw materials into smaller ones, and the small raw materials will pass through the guide block 5 into the gap between the upper grinding block 6 and the lower grinding block 7, the motor 8 will drive the lower grinding block 7 to rotate, thereby grinding the raw materials, and the ground raw materials will fall on the filter screen 10, and the vibrator will drive the filter screen 10 to vibrate, so that the raw materials that can pass through the filter screen 10 will fall. On the guide plate 11 below, the raw materials then flow out from the opening at the lower end of the guide plate 11. The raw materials that have not passed through the filter screen 10 will move to the opening at the lower end of the filter screen 10 under the action of vibration, and then enter the collection box 12. When the raw materials are ground, remove the collection box 12 and observe its interior to see if there are any raw materials. If so, pour the raw materials inside the collection box 12 back into the device, and then reinstall the collection box 12. If the gap between the upper grinding block 6 and the lower grinding block 7 becomes larger, making the grinding effect worse, then extend the cylinder axis of the cylinder 2 9, which will make the gap between the upper grinding block 6 and the lower grinding block 7 smaller, thereby making the ground raw materials smaller.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
