It is one of the commonly used equipment in the processing of metal and non-metallic ores. Crusher can be divided into three types according to the size of feed and discharge particles: coarse crushing, medium crushing and fine crushing. Common crushing machines include jaw crusher, gyratory crusher, cone crusher, roll crusher, hammer crusher and impact crusher.

A screening feed pipe is arranged above the feed hopper base, and a rotating connection seat is fixedly connected to the outer surface of one side of the screening feed pipe, and one end of a connecting rod is rotatably installed inside the rotating connection seat, and the other end of the connecting rod is provided with a circular hole, and a fixed connecting column is passed through the inside of the circular hole, and the fixed connecting column is fixedly connected to the upper outer surface of the screening wheel and is located at the edge position of the upper outer surface of the screening wheel, and the screening wheel is fixedly installed at one end of the rotating shaft of the AC motor, and the screening wheel and the rotating shaft of the AC motor are coaxial.

[0004] However, the above-mentioned feeding mechanism has the following disadvantages: the device can make the feed hopper reciprocate to screen the raw materials by arranging the driving wheel and the screening plate, but the raw materials remaining on the screening plate need to be cleaned up later, which is troublesome. Excessive accumulation will also affect the screening efficiency of the screening plate. At the same time, after the screening plate has screened the raw materials for a long time, some of the apertures on the screening plate may be blocked, reducing the service life of the screening plate.

[0005] Therefore, we propose a crusher feeding structure to solve this problem.
