A pushing mechanism 400 is arranged in the through groove 300, and the pushing mechanism 400 includes a pushing baffle 401 located inside the filter box 200 and used for closing and opening the discharge port 103, and a telescopic push rod 402 is arranged on the outer wall of the pushing baffle 401. The utility model can set a pushing mechanism 400 at the discharge port 103 of the crusher to push the larger materials on the filter plate back into the crusher, so as to achieve multiple sufficient crushing operations on the materials, without taking out and collecting the larger materials and then putting them back, which greatly improves the processing efficiency and saves time and effort.
[0021] According to one embodiment of the utility model, Figure 1-4 As shown, the filter box 200 is a box-type structure with a hollow side wall on the side close to the discharge port 103. A plurality of filter holes are provided on the bottom side wall of the filter box 200. The upper and lower sides of the filter box 200 are fixed on the side walls of the crushing barrel 101. The utility model can screen and filter the crushed material in the crushing barrel 101 through the filter holes at the bottom of the filter box 200, which is more convenient and efficient in realizing the filtering operation of the crushed material during the crushing operation.
[0022] According to another embodiment of the present invention, Figure 1 , Figure 2 and Figure 3As shown, a fixing frame 500 is arranged on the outside of the filter box 200, and the fixing frame 500 is arranged on the outer side wall of the side of the discharge port 103. The fixed end of the telescopic push rod 402 is fixed on the fixing frame 500, and the output rod of the telescopic push rod 402 passes through the through slot 300, and the output rod end of the telescopic push rod 402 is fixed together with the back of the push baffle 401.

[0024] The use of the utility model:
[0025] First of all, it should be made clear that the filtering component involved in the utility model is mainly used for the automatic filtering operation of the material after being crushed by the crusher. The utility model takes the filtration in the process of silicon nitride processing and crushing as an example to explain its method of use in detail. When it is necessary to crush the silicon nitride raw material, the output shaft of the crushing motor at the bottom of the crushing is started to rotate to drive the crushing blade 102 to rotate, and then the silicon nitride raw material to be crushed is put into the crushing barrel 101. At this time, the output rod of the telescopic push rod 402 is in a state of extending to push the push baffle 401 to seal the discharge port 103. After a certain period of crushing, the telescopic push rod 402 is started to retract to bring the push baffle 401 away from the discharge port 103, and the discharge port 103 is opened. The crushing and stirring action of the high-speed rotating crushing blade 102 realizes the crushing of the material, and at the same time drives the crushed material to rotate at high speed. The crushed material is thrown out through the discharge port 103 under the action of centrifugal force. The filtering effect of the filter box 200 realizes the classification and collection of materials. When too much material accumulates on the bottom of the filter box 200, the output rod of the telescopic push rod 402 is started to extend to push the push baffle 401 to push the material back into the crushing box. The output rod of the telescopic push rod 402 is extended to push the push baffle 401 to move to the side close to the discharge port 103 to push the material blocked on the filter hole at the bottom of the filter box 200 back into the crushing box and be rotated to perform repeated crushing operations by the crushing blade 102. There is no need to take out and collect larger materials before putting them in, which greatly improves the processing efficiency. The utility model can set a pushing mechanism 400 at the discharge port 103 of the crusher to push the larger materials on the filter plate back into the interior of the crusher, so as to realize multiple sufficient crushing operations on them. There is no need to take out and collect larger materials before putting them in, which greatly improves the processing efficiency and saves time and effort.

[0027] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
