Problems solved by technology

[0002] The quality of different iron ores is different, that is, the iron content in them is different, but the existing mining crushing device does not have a device that can screen according to the quality of the iron content. Therefore, we now provide A crushing and screening device for mining, which can produce better iron ore by changing the magnetic screening of the electromagnetic plate

Abstract

The invention discloses a crushing and screening device for mining, and relates to the field of devices for mining. The ore enters through a feed inlet and enters into a crushing hopper under the action of a guide plate, and driven components on the two sides of a driving wheel drive a rack to ascend / descend respectively, so that a breaking hammer performs reciprocating lifting motion under the action of a driving mechanism in order to achieve hammering and breaking work; through holes are arranged in the crushing hopper; screening and breaking can be performed simultaneously; due to the arrangement of an electromagnetic plate, the ore with higher iron content can ascend along a conveyor belt under the magnetic action, and conversely, the resistance of the ore is smaller and the ore can only descend along the conveyor belt; a vibrating mechanism and a connecting spring are further arranged to promote a conveying mechanism to vibrate in order to prevent the ore from being accumulated onthe conveyor belt; a lifting mechanism drives a telescopic column to ascend and descend, so that the effective length of the connecting spring can be changed; and when the telescopic column goes deepinto a connecting seat, the connecting spring loses transverse freedom, so that the degree of stability of the conveying mechanism is increased.

Description

technical field [0001] The invention relates to the technical field of mining devices, in particular to a crushing and screening device for mining. Background technique [0002] The quality of different iron ores is different, that is, the iron content in them is different, but the existing mining crushing device does not have a device that can screen according to the quality of the iron content. Therefore, we now provide The utility model relates to a crushing and screening device for mining, which can produce relatively good iron ore by changing the magnetic screening of an electromagnetic plate. Contents of the invention [0003] The object of the present invention is to provide a crushing and screening device for mining to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A crushing and screening device for mining, comprising a crushi...
