Crushing and screening device for mining

Abstract

The invention discloses a crushing and screening device for mining. The crushing and screening device for mining comprises a supporting mechanism, a dust falling mechanism and a first crushing mechanism, wherein the supporting mechanism comprises a crushing box, a crushing box door, sound absorption cotton, a top cover, a feeding opening, supporting legs, telescopic sleeves and springs; the supporting legs are connected with the crushing box through the telescopic sleeves; a second crushing mechanism is arranged below a first crushing roller and a second crushing roller; a transmission gear is arranged on the rear side of the crushing box; and belt shafts are arranged on a motor and the first crushing roller. The crushing and screening device for mining is provided with an atomizing spray head, and the atomizing spray head can spray water to dust blown out from a feeding port in the crushing process, so that dust sedimentation can be accelerated, meanwhile, and the dust can be prevented from polluting the surrounding working environment; and meanwhile, the telescopic sleeves and the springs are arranged, so that the telescopic sleeves and the springs can effectively reduce the impact of the vibration of the device on self parts during working, and then the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a crushing and screening device for mining. Background technique [0002] In the process of mining, it is necessary to use a crushing device to crush the stones. The existing crushing device is prone to dust when crushing the stones, and it is easy to cause pollution to the surrounding environment. On the other hand, the existing Most of the crushing devices do not have the function of screening, so the crushed stone needs to be transferred to other equipment for volume screening, which is not convenient to use. To solve the above problems, the existing equipment needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a crushing and screening device for mine development, to solve the phenomenon that some crushing devices proposed in the background technology are prone to dust diffuse when crushing stones, and then easily cause ...
