Abstract

The invention discloses an ore smashing and screening device for mining. The ore smashing and screening device comprises a screening box, wherein lifting mechanisms are installed at the four corners of the bottom of the screening box, idler wheels are installed at the bottoms of the lifting mechanisms, an installing plate is in screw joint with the center of the bottom of the screening box, a vibration motor is fixed to the bottom of the installing plate, a first screening plate and a second screening plate are installed in an inner cavity of the screening box respectively, fixation blocks aresymmetrically installed at the left and right ends of the first screening plate and the second screening plate, reset springs are connected to the bottoms of the fixation blocks, and supporting plates are installed at the ends, away from the fixation blocks, of the reset springs. According to the ore smashing and screening device, when to-be-smashed ore falls into the upper positions of feeding plates through charging openings, the feeding plates guide the ore into the upper positions of movable rods, at this moment, positioning springs are compressed to make the movable rods rotate downwards, then the ore continues to fall, thus the smashing and screening device can control the falling speed of the ore to a certain degree, and the situation that the smashing effect of the device is influenced when too much ore falls is avoided.

Description

technical field [0001] The invention relates to the technical field of mining auxiliary equipment, in particular to an ore crushing and screening device for mining. Background technique [0002] Ore can be divided into metallic minerals and non-metallic minerals. With the continuous development of the mining industry, the ore needs to be crushed and screened before transmission to facilitate the transportation of ore. However, there are still some problems in the existing equipment: [0003] The traditional device cannot control the ore dropping speed to a certain extent, so that the crushing effect of the device is poor. In addition, the traditional device cannot perform layered screening according to the size of the ore, thereby reducing the practicability of the device. [0004] Based on this, the present invention designs a mining ore crushing and screening device to solve the above-mentioned problems. Contents of the invention [0005] The object of the present inven...
