Mine gravel treatment device capable of screening

Abstract

The invention discloses a mine gravel treatment device capable of screening. A feeding opening is formed in one end of a feeding box, the bottom end of the feeding box is connected with an extrusion mechanism through a bolt, the extrusion mechanism comprises an extrusion box, an extrusion cavity, a mounting plate, a fixed clamping plate, a sliding groove, a sliding plate, a movable clamping plate,a push plate, a limiting plate, an oval rotating rod, a first rotating motor, a sleeve, a fixing rod and a tensioning spring, and the bottom end of the feeding box is connected with the extrusion boxthrough the bolt. The mine gravel treatment device capable of screening is scientific and reasonable in structure and safe and convenient to use, the extrusion mechanism is arranged, first-step crushing treatment is carried out on stone through the extrusion box, the oval rotating rod is driven to rotate through the first rotating motor, and the movable clamping plate is continuously pushed to move through cooperation of the push plate, so that the movable clamping plate is matched with the fixed clamping plate to extrude and crush the stone, the size of the stone is reduced, the subsequent crushing of the stone is further facilitated, and the crushing effect of the stone is improved.

Description

technical field [0001] The invention relates to the technical field of mine crushing stone processing, in particular to a mine crushing stone processing device that can be screened. Background technique [0002] Mine refers to an independent production and operation unit that mines ore with a certain mining boundary. Ore refers to a mineral aggregate from which useful components can be extracted or has a certain performance that can be used. In the process of ore processing, it needs to use Crusher, crushing mine gravel; [0003] However, the existing crushing device only crushes the stone once, and the effect of crushing is poor, which affects the precision of crushing. In addition, some larger stones are easy to cause damage to the crushing roller, which reduces the service life of the crushing roller and reduces the The efficiency of production, so for these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a mine crushing t...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a mine crushing stone processing device that can be screened, which can effectively solve the problem of only one crushing process for stones proposed in the above background technology, the crushing effect is poor, and the crushing accuracy is affected at the same time. It is easy to cause damage to the crushing roller, which reduces the service life of the crushing roller and reduces the production efficiency
