a pulverizer

Abstract

The invention relates to a crusher, and relates to the technical field of material crushing devices. The crusher comprises a case and a motor; a feeding inlet and a discharging outlet are formed in the upper end and the lower end of the case correspondingly, a crushing cavity is formed in the case, and an output shaft of the motor is arranged in the crushing cavity in a penetrating mode and connected with a material crushing piece; a filtering net arranged on the discharging outlet in a covering mode is arranged in the crushing cavity, and a plurality of fastening pieces are arranged on the cavity wall, close to the motor, of the crushing cavity in the circumferential direction; each fastening piece comprises two symmetrically-arranged fastening plates, wherein a net embedding groove is formed between the two fastening plate; and the filtering net is connected into the net embedding grooves in a clamped mode and makes contact with the groove bottoms of the net embedding grooves. According to the crusher, the multiple sets of fastening pieces which are each composed of the two fastening plates are arranged, wherein the corresponding net embedding groove for clamped connection of thefiltering net is formed between the two fastening plates, thus the filtering net is detachably connected into the crushing cavity, and the filtering net is replaced and cleaned conveniently.

Description

technical field [0001] The invention relates to the technical field of material crushing devices, in particular to a crushing machine. Background technique [0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. Existing pulverizers such as the publication number are a Chinese invention patent of CN106914310A, which discloses a kind of agricultural pulverizer, including a pulverizer body, and the pulverizer body includes a feed hopper, a pulverization chamber housing, a pulverization block, a filter screen, Machine base, discharge port and driving mechanism, the feed hopper is connected to the upper end of the crushing chamber shell, the discharge port is set at the lower end of the crushing chamber shell, the crushing chamber shell is installed on the machine base, and the crushing block is located in the crushing chamber shell The inside of the body rotates with the shell of the crushing chamber, the filter screen is located un...

AI Technical Summary

Problems solved by technology

[0003] The above existing technical solutions have the following defects: when the pulverizer crushes materials during use, the crushed materials will be exported from the discharge port through the filter screen, and part of the crushed materials will remain in the filter during the export process. On the Internet, after a long working time, the residual materials will gradually block the filter screen so that the subsequent crushed materials cannot pass through the filter screen. At this time, the filter screen needs to be replaced or cleaned to ensure that the crushed materials can be exported normally, but The filter screen of the above pulverizer is fixed on the shell of the crushing chamber, which makes it more troublesome to replace and clean the filter screen
