Split type crushing mechanism with rocker arm power

Abstract

The invention relates to a split type crushing mechanism with rocker arm power. The split type crushing mechanism comprises a support, a connecting seat, a crushing tooth assembly and a mining machine rocker arm, wherein the support comprises a base, a front supporting plate and a rear supporting plate; the base and the connecting seat are fixed on the rocker arm; the crushing tooth assembly comprises a rotating shaft, a plurality of shaft sleeves and crushing teeth; the shaft sleeves sleeve the rotating shaft side by side; the crushing teeth are arranged on the shaft sleeves; the front part and the rear part of the rotating shaft are respectively supported on the front supporting plate and the rear supporting plate in a rotating manner; the front end of the rotating shaft penetrates through the front supporting plate and is positioned in an inner cavity of the connecting seat; the rear end of a transmission gear in the rocker arm extends out of the rocker arm and is positioned in the inner cavity of the connecting seat; the rear end of the transmission gear is in transmission connection with the front end of the rotating shaft through a transmission system; the front supporting plate and the rear supporting plate can be arranged at different positions of the base; and the connecting seat can also be arranged at different positions of the rocker arm. The split type crushing mechanism can be used for a mining machine for mining a thin ore bed or a high-grade thin ore bed, and rocks are effectively crushed, so that the rocks can smoothly pass through the lower part of the mining machine rocker arm, and accumulation is avoided.

Description

technical field [0001] The invention relates to a crushing mechanism for a mining machine, especially suitable for a mining machine for mining relatively thin ore layers or high-grade thin ore layers. Background technique [0002] In order to adapt to the mining of thin or high-grade thin ore seams, the rocker arm of the high-power (high torque) cutting system is usually used on the bauxite mining machine. The height of the rocker arm is low, the structure is compact, and the power density is high. The advanced cutting motor occupies a large space in the front and rear direction, so that there is not enough space between the cutting motor and the cable trough to set up a conventional crushing device. However, in the actual mining of mining machines, there are often a large number of high-hardness bauxite rocks. After entering the conveyor, these bauxite rocks need to pass under the position where the cutting motor of the rocker arm is located, but many of them are large rock...

Problems solved by technology

[0002] In order to adapt to the mining of thin or high-grade thin ore seams, the rocker arm of the high-power (high torque) cutting system is usually used on the bauxite mining machine. The height of the rocker arm is low, the structure is compact, and the power density is high. The cutting motor occupies a large space in the front and rear direction, so that there is not enough space between the cutting motor and the cable trough to set up a conventional crushing device

However, in the actual mining of mining machines, there are often a large number of high-hardness bauxite rocks. After entering the conveyor, these bauxite rocks need to pass under the position where the cutting motor of the rocker arm is located, but many of them are large rocks. Unable to pass through, the final accumulation will cause the conveyor to fail to convey, and it needs to be shut down for manual cleaning, which is time-consuming and laborious, and also affects production capacity
