Fishing reef production raw material crushing device for crushing oyster shells and steel slag

Abstract

The raw material crushing device comprises a machine body, supporting legs are fixedly installed at the four corners of the lower end of the machine body, a feeding channel is formed in the right side of the upper end of the machine body, a discharging opening is formed in the lower end of the machine body, a main roller shaft is arranged in the middle of the inner side of the machine body, and a feeding channel is formed in the lower end of the machine body; short connecting shafts are fixedly connected to the front end and the rear end of the main roller shaft, the short connecting shafts at the front end and the rear end of the main roller shaft and the front side wall and the rear side wall of the machine body form bearing connecting structures correspondingly, the short connecting shaft at the front end of the main roller shaft is in key connection with a large gear, and the right side of the large gear is meshed with the left side of a small gear. According to the fishing reef production raw material crushing device for crushing the oyster shells and the steel slag, the size of crushed particles can be conveniently adjusted, dust generated in the crushing process can be simply and efficiently treated in a centralized mode, and the dust is prevented from affecting the body health of workers.

Description

technical field [0001] The invention relates to the technical field of fishing reef production, in particular to a raw material crushing device for fishing reef production that crushes oyster shells and steel slag. Background technique [0002] The crushing device is a kind of equipment for crushing materials. Usually, rollers are used to crush the materials. In the production process of fish reefs that use oyster shells and steel slag as raw materials, the crushing device needs to be used to crush the oyster shells and steel slag first. Shred processing. [0003] However, the existing raw material crushing device for fishing reef production that crushes oyster shells and steel slag is inconvenient to adjust the size of the crushed particles, and it is not convenient to clean up the dust generated during crushing. According to the characteristics of a large number of fish gathered near the fishing reef , fishermen will increase the output of fishing grounds by putting artif...
