Abstract

The invention belongs to the technical field of ore mining, and particularly relates to an ore feeding and screening device. According to the following scheme, the ore feeding and screening device comprises a screening box, wherein a feeding port is formed in one side of the top end of the screening box, and a primary feeding screen is fixedly installed on the inner wall of the feeding port through bolts; a steel wire mesh hopper is welded to the inner wall of the end, close to the primary feeding screen, of the screening box, and a material breaking hopper barrel is welded to the bottom end of the steel wire mesh hopper; notches which are distributed at equal intervals are formed in the material breaking hopper barrel, and wall thorns which are distributed in a staggered mode with the notches are welded to the inner wall of the material breaking hopper barrel; and fixing cross rods penetrating through the steel wire mesh hopper are horizontally welded to the two sides of the inner wall, close to the top end, of the screening box. According to the ore feeding and screening device, through an arranged electric telescopic rod, when an extension rod of the electric telescopic rod is drawn back, a second piston plate can be pushed by utilizing an L-shaped driving rod, so that a first piston plate and a driven side rod are pushed to move upwards by utilizing the hydraulic principle; and otherwise, the electric telescopic rod extends and extends, so that the driven side rod moves downwards, and then a screen disc swings back and forth.

Description

technical field [0001] The invention relates to the technical field of ore mining, in particular to an ore feeding screening device. Background technique [0002] Ore refers to mineral aggregates from which useful components can be extracted or which have certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components in an ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are usually expressed in percentages. The ore grade is often used to measure the value of ore, but the composition and harmful impurities of the gangue (useless minerals in the ore or minerals with very little useful content that cannot be used) and the amount of harmful impurities in the ore also affect the value of the ore. Ore is generally composed of ore minerals and gangue minerals. Ore minerals refer to metal or non-metallic minerals that can be uti...
