[0035] Working principle: When it is necessary to pre-treat the material, the crusher 1 can be started first, and then the raw materials can be put into the crusher 1. The crusher 1 will crush the material, and then the crushed material will fall to the top of the filter plate 23 under the action of gravity. The material of the required size will pass through the filter plate 23 and enter the collection box 31, while the material of oversized size will move downward along the top of the filter plate 23 and enter the separation box 22. At the same time, when the crusher 1 is working, the belt will drive the shaft 21 to rotate, and the shaft 21 will drive the cam 211 to rotate. When the cam 211 rotates, it will continuously hit the filter plate 23 to assist the movement of the material on its surface. When vibration is not required, the adjusting rod 25 can be pushed upward to drive it to move upward. When the block 26 and the receiving block 28 are aligned, the push spring 27 will push the block 26 to make it fit into the receiving block 28 and squeeze the push block 29 to expose it to the left. The material passing through the inside of the diverter box 24 will move downward to contact the blocking plate 32 and enter the collection box 31 along its top.

[0036] When enough material has accumulated inside the collecting box 31, you can first hold the handle 38 and then move the fixed block 39 to the right to disengage it from the fixed plate 37. Then you can move the handle 38 downward to drive the blocking plate 32 to move downward. After the bottom end of the blocking plate 32 contacts the top of the blocking block 33, the subsequent material will be blocked at the top of the blocking plate 32 and cannot enter the interior of the collecting box 31. At the same time, the discharge plate 35 will move downward to disengage from the bottom of the discharge block 36. At this time, the material inside the collecting box 31 will be separated from the inside of the discharge plate 35 and enter the internal mixing equipment. When feeding, the subsequent material cannot enter the interior of the internal mixing equipment, so that the effect of controlling the discharge of materials can be achieved.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
