Coal mine underground multifunctional stirring, loading and unloading device

Abstract

The invention discloses a coal mine multifunctional stirring, loading and unloading device. The device is characterized in that a fixed rack is fixedly arranged along the running direction of a roadway car, the fixed rack comprises a longitudinally horizontal rail, a movable roller driven by a movable rack driving motor on a longitudinally horizontal rack is supported by the longitudinally horizontal rail; two supporting cylinders are respectively fixedly arranged at the two ends of the longitudinally horizontal rack, a transverse horizontal frame rail which is supported by the supporting cylinders and is driven by jacking power provided by the supporting cylinders is fixedly arranged at the top of each supporting cylinder; a grab bucket type loading and unloading machine is adopted, loading and unloading machine supporting roller assemblies which are arranged at the two side parts of the case of the grab bucket type loading and unloading machine and are driven by a motor are supported by the transverse horizontal frame rail, and the transverse horizontal frame rail is taken as a rolling guide rail; and a lift cylinder is arranged in the case of the loading and unloading machine.

Description

Coal mine underground multifunctional mixing and loading and unloading device technical field The invention relates to a multifunctional mixing and loading and unloading device for underground coal mines, which is used for mixing and loading and unloading various powders and granules in roadways such as tunneling working faces and coal mining working faces in underground coal mines. Background technique Due to the harsh working environment of coal mines, mine trucks need to be used to transport a large amount of loose materials, such as stones and yellow sand, during the working process of the excavation face and coal mining face. Due to the needs of coal mine production and the limitation of the mine car structure, a large Most of the loose materials are manually loaded and unloaded with shovels, the production efficiency is low, and the labor intensity of workers is high. At the same time, due to the harsh working environment of coal mines, the excavation working face a...

Problems solved by technology

Due to the harsh working environment of coal mines, mine trucks need to be used to transport a large amount of loose materials, such as stones and yellow sand, during the working process of the excavation face and coal mining face. Due to the needs of coal mine production and the limitation of the mine car structure, a large Most of the loose materials are manually loaded and unloaded with shovels, the production efficiency is low, and the labor intensity of workers is high

At the same time, due to the harsh working environment of coal mines, the excavation working face and the coal mining working face have small space, and a large amount of dust is generated when mixing, loading and unloading loose materials, which will cause great damage to human health. Wear a dust mask to prevent dust The effect is not ideal, and it also affects the natural breathing of the human body. Therefore, reducing the dust concentration in the working environment and improving production automation to reduce manpower are the fundamental solutions to the problem.
