[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up a vibrating feeding mechanism, when feeding the crusher is required, the material can be poured into the U-shaped material transfer trough. At this time, the motor is started. The motor drives the first rotating shaft on the fixed plate to rotate through the pulley and belt. The first rotating shaft drives two eccentric wheels to rotate, so that the U-shaped material transfer trough vibrates under the action of the first spring, and the material in the U-shaped material transfer trough is guided into the rectangular box, enabling the material to be evenly and continuously conveyed to the feeding port of the crusher, ensuring that the crusher can work continuously and stably. The material is agitated and arranged in the feeding trough, thus avoiding the situation of blockage or uneven feeding during the feeding process. The feeding speed and quantity of the material can be adjusted according to needs to adapt to the processing capacity of the crusher. By adjusting the amplitude and frequency of the vibrating feeding mechanism, different degrees of material conveying can be achieved, so as to maximize the processing capacity of the crusher, and the energy consumption during the start-up and stop processes of the crusher can be reduced;

[0017] 2. By setting up a crushing mechanism, when the material enters the rectangular box, the motor will also drive the second rotating shaft to rotate. The second rotating shaft drives the moving jaw plate to swing on the connecting rod through the eccentric shaft and the connecting block, and the material is clamped between the moving jaw plate and the static jaw plate for crushing, so that the material can be effectively crushed, ground or sheared, thus meeting the processing requirements of different industrial fields. The raw material can be effectively crushed, making various components inside the raw material easier to be released and utilized, improving the utilization rate of the raw material, reducing the production cost, and helping to reduce the generation of waste. The raw material can be quickly and continuously crushed, reducing the waiting and停顿 time in the production process.

[0018] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
