Ore crushing device with dust prevention structure for mine mining

Abstract

The invention discloses an ore crushing device with a dust prevention structure for mine mining. The ore crushing device with the dust prevention structure for mine mining comprises a first crushing cavity, a second crushing cavity, a filter plate, a flowing guide dust prevention plate and a filter screen. A feeding port is formed in the upper end of the first crushing cavity, a second rotary shaft is connected to the output end of a second driving motor, the filter plate is mounted in the second crushing cavity, discharging ports are formed in the lower ends of the first crushing cavity and the second crushing cavity, and valves are mounted on the surfaces of the discharging ports. The head and tail ends of the filter screen are connected with the inner wall of a material collecting box through mounting blocks, and a damping device is mounted between supporting frames. According to the ore crushing device with the dust prevention structure for mine mining, a main position rod can be driven to rotate in the function of driving motors, a first time of striking and stirring for crushed stone is facilitated, so that the crushed stone generates cracks, each surface of the crushed stonecan be struck completely, so that convenience is brought for the subsequent crushing working, and the improvement of the working efficiency of ore crushing is facilitated.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to an ore crushing device with a dust-proof structure for mining. Background technique [0002] Mining mining technology refers to the mining technology of valuable natural mineral resources by manual or mechanical means. According to the different burial depths of ore deposits and the requirements of technical and economic rationality, mining technology is divided into open-pit mining and underground mining. Open-pit mining is adopted for the surface and shallow buried parts, and underground mining is used for deep parts. For an ore body, whether to use open-pit mining or underground mining depends on the occurrence status of the ore body. If open-pit mining is used, how deep should be adopted? , there is a depth boundary problem here, and the determination of the depth boundary mainly depends on economic benefits. Generally speaking, if the boundary stripping is less than or equal...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of ore crushing device with dust-proof structure for mining, to solve the problem that the ore crushing device for mining used in the above-mentioned background technology has poor crushing efficiency of ore, and the crushing effect on the ore after crushing The particles do not have the function of sieving, which is not convenient for the user to separate and process them separately, and does not have the function of drainage during the crushing process, so it is not convenient for the gravel to be guided smoothly into the collection box, and it is difficult to guide the gravel into the collection box smoothly during the drainage process. There is no dust-proof function in the process, it is not convenient for users to use it, and it is not conducive to protecting the surrounding environment and people.
