Impact type crushing device for ore mining

Abstract

The invention relates to the technical field of ore extraction, in particular to an impact type crushing device for ore extraction. The device at least comprises a bottom plate, a fixing plate is installed on the surface of the bottom plate, a shell is installed on the surface of the fixing plate, a motor is arranged in the shell, and one end of the motor is connected with a rotating rod; fixing blocks are arranged at the ends of the lead screws, lead screw nuts are connected to the surfaces of the lead screws in a threaded mode, limiting blocks are arranged on the lead screw nuts, and a rupture plate is installed at the bottoms of the lead screw nuts; and the transmission part is used for synchronously connecting the output end of the motor with the end part of the screw rod. The motor drives the rotating rod to rotate, the rotating rod drills the surface of the ore to break the ore, under connection of the transmission part, the lead screw rotates synchronously, the breaking plate permeates into the gap, the gap is gradually enlarged, and convenience is provided for follow-up carrying or secondary breaking of the ore. Meanwhile, the frequency of damage to the single rotating rod during working is also reduced due to alternate operation of the rotating rod and the rupture plate.

Description

technical field [0001] The invention relates to the technical field of ore mining, in particular to a crushing device for ore mining based on an impact type. Background technique [0002] Ore mining is a general term for mining ore materials in current mines. At present, when ore is mined, small-scale drill equipment is used to perform fracture mining on the mine field. Among them, the drill equipment directly contacts the surface of the mine ground, and is driven by a motor to rotate into the inside of the ore, causing the ore to be split and broken. In the process, the drill bit drills Excessive vibration will be generated when entering the mine, which requires a lot of manpower to control the motor and the entire equipment. When the manpower is exhausted, manpower cannot control the equipment, causing safety hazards, and when the ore is broken by this equipment, After the drill bit breaks the ore, it cannot expand the gap formed in the broken ore, so that the ore is not ...

AI Technical Summary

Problems solved by technology

At present, when ore is mined, small-scale drill equipment is used to perform fracture mining on the mine field. Among them, the drill equipment directly contacts the surface of the mine ground, and is driven by a motor to rotate into the inside of the ore, causing the ore to be split and broken. In the process, the drill bit drills Excessive vibration will be generated when entering the mine, which requires a large amount of manpower to control the motor and the entire equipment. When the manpower is exhausted, the manpower cannot control the equipment, causing safety hazards, and when the ore is broken by this equipment, After the drill bit breaks the ore, it cannot expand the gap formed in the broken ore, so that the ore is not completely separated, which will affect the subsequent handling or crushing of the ore again. Moreover, at present, only a single drill bit is used for the cracking operation , and no other parts are used in conjunction with it, so that the drill bit will be damaged after frequent and long-term use, which affects the efficiency of ore mining, and also leads to a high frequency of maintenance or replacement of this equipment
