Description

Technical Field

[0001] The utility model relates to the technical field of raw material sorting equipment, in particular to a raw material sorting equipment with convenient screen replacement. Background Art

[0002] As we all know, the process of bulk materials being divided into different particle sizes through one or several layers of screens is called screening. The screening machine is a vibrating screening machine that uses the relative movement between the bulk material and the screen surface to allow some particles to pass through the screen holes, and can separate materials such as sand, gravel, and crushed stone into different grades according to particle size. The screening process of the screening machine is generally continuous. After the screened raw materials are fed to the screening machine (referred to as the sieve), the materials smaller than the size of the screen holes pass through the screen holes, which are called undersize products; the materials larger than the size of the screen holes are continuously discharged from the screen surface, which are called oversize products;

[0003] When sorting raw materials, different screen specifications are required according to the screening requirements, and the screen needs to be replaced in the screening device. The existing screening device is troublesome and laborious to replace the screen, which increases the labor cost. In view of the above problems, the present application designs a raw material sorting equipment with convenient screen replacement. Utility Model Content
