[0002] A crusher is a machine that crushes large-scale solid raw materials to the required size. It is widely used in the feed, pharmaceutical, food, agricultural production and chemical industries. According to the size of the material being crushed or the material being crushed, crushers can be divided into coarse crushers, pulverizers and ultrafine pulverizers. There are four types of external forces applied during the crushing process: shearing, impact, crushing and grinding. Through the action of these four external forces, the raw materials are crushed.

[0003] Application No. 2020203628386 discloses a crusher discharge anti-blocking device, including a crusher housing. A crushing roller is installed inside the crusher housing. A servo motor is fixedly connected to the outer wall of one side of the crusher housing via a fixed frame. A first rotating shaft is fixedly connected to the shaft wall of the output shaft of the servo motor. The other end of the first rotating shaft passes through the crusher housing. The beneficial effects achieved by this utility model are: the crusher discharge anti-blocking device of this utility model has a simple structure and is easy to use. A second rotating shaft is connected to the first rotating shaft on the crusher via a coupling, so that when the crusher is crushing, it can drive a third rotating shaft to rotate through a transmission wheel and a transmission belt. When the third rotating shaft rotates inside the discharge pipe, it can drive a material-distributing roller to rotate in the discharge pipe, thereby dispersing the material in the discharge pipe and allowing the material in the housing to be discharged more smoothly.

[0004] The above technical solutions have alleviated the problem of material blockage at the discharge port of the crusher to some extent, but the problems of material blockage at the discharge port and low crushing efficiency still exist. Utility Model Content

[0005] This utility model proposes an anti-clogging spiral pulverizer, which solves the problem that the discharge port of existing pulverizer anti-clogging devices is prone to clogging and the pulverizing efficiency is low.

[0006] The technical solution of this utility model is as follows: an anti-clogging spiral pulverizer, comprising a bearing housing, a centrifugal fan, a cyclone separator, a motor, an upper housing, a lower housing, a feed hopper, a pulverizing blade assembly, an auger, and a discharge port. The upper housing and the lower housing are rotatably connected. The upper housing has a feed hopper at its front end, and the lower housing has a bearing housing at its top. A pulverizing blade assembly is installed inside the bearing housing. A screen is located below the pulverizing blade assembly, and an auger is located below the screen. The auger is rotatably connected to the lower housing. A centrifugal fan is located at the end of the auger shaft. The centrifugal fan is connected to the cyclone separator through a pipe. The bottom of the cyclone separator is the discharge port. The pulverizing blade assembly and the auger are driven by a motor.

[0007] Preferably, a frame is connected to the bottom of the lower box body, and casters are connected to the bottom of the frame.

[0008] Preferably, pulley wheels are installed at the ends of the crushing knife group and the auger shaft, a pulley wheel is provided at the end of the motor shaft, and a V-belt is arranged between the pulley wheels.

[0009] Preferably, protective covers are provided on the outer edges of the motor pulley wheel, the crushing knife group pulley wheel and the auger pulley wheel.

[0010] Preferably, the frame is welded by angle steels, and a plurality of kidney-shaped holes are provided at the top of the frame.

[0011] Preferably, the upper box body and the lower box body are formed by casting.

[0012] Preferably, the feed hopper is formed by sheet metal bending and welding.

[0013] Preferably, a magnet is fixed at the end of the feed hopper.

[0014] Principle of the present utility model: In order to solve the problems that the discharge port of the existing anti-blocking pulverizer is prone to blockage and the pulverizing efficiency is low, an auger is added below the sieve of the existing pulverizer, and a centrifugal fan is connected to the end of the auger. The pulverized material is conveyed to the centrifugal fan by the auger, and the centrifugal fan uses wind power to convey the material to the cyclone separator through a pipeline. The material is discharged through the discharge port at the bottom of the cyclone separator, and impurities are discharged from the top of the cyclone separator to complete the pulverizing operation. Compared with the existing anti-blocking pulverizer, it is not easy to block, it is not easy to accumulate materials below the sieve, and the pulverizing efficiency is high. Especially for materials such as straw, the quality is light after pulverization and it is easy to accumulate below the sieve, affecting the pulverizing work efficiency. In addition, the negative pressure suction generated by the centrifugal fan sucks away the air in the pulverizing cavity, accelerating the material to pass through the sieve and further improving the pulverizing efficiency.

[0015] Advantages of the present utility model: An anti-blocking spiral pulverizer has a scientific and reasonable structural design, low manufacturing cost, the pulverized material is not easy to accumulate below the sieve, has a good anti-blocking effect, high pulverizing quality and high pulverizing efficiency.
