Qualified materials fall through the screen below to achieve the purpose of screening. It can crush a variety of materials and has strong versatility. It is currently the main equipment for feed production and farmers.

[0003] Although the crusher can crush most materials, the fiber structure of some longer materials is relatively coarse, and the crushing effect is not good. In addition, the more functions the crusher has, the larger the size. In order to improve reliability, multiple components are integrated into one design, which is not only difficult to produce but also not conducive to transportation. For this reason, we proposed a new type of crusher to solve the above problems. Utility Model Content

A plurality of self-suction plates 17 are installed on the hammer rack plate 3 at one end. When the self-suction plates 17 rotate, a negative pressure area is formed at the position of the main shaft 2 through centrifugal force to absorb external granular materials. Specifically, a circular baffle 22 is installed at one end of the plurality of self-suction plates 17 so that the materials thrown out by the centrifugal force are not sucked out. The material moves radially, and a suction structure is provided on one side of the upper cover 10. The suction structure is located at the main position close to the main shaft 2, which is used to communicate with the outside world and suck the material. A crushing assembly is installed between the multiple hammer rack plates 3 to crush the material entering the casing 1. Specifically, a screen 5 is provided at the bottom of the casing 1, and the screen 5 separates the casing 1 into a crushing chamber and a material-dropping chamber. The material is continuously crushed in the crushing chamber, and the qualified crushed material falls into the material-dropping chamber through the screen 5 to complete the screening. An air regulating port is provided on one side of the material-dropping chamber to adjust the suction wind force;

[0032] A negative pressure bellows 13 is also installed at one end of the casing 1 for absorbing the material in the blanking cavity. Specifically, the main shaft 2 extends into the negative pressure bellows 13, and a negative pressure wind disc 14 is installed at one end of the main shaft 2 extending into the negative pressure bellows 13.
