Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mining equipment, and specifically relates to a self-moving type crushing and rehandling unit. BACKGROUND

[0002] The existing open-pit coal mining mainly applies the following two processes: one is the intermittent mining process of single-bucket electric shovel (or hydraulic excavator) + truck; and the other is the semi-continuous mining process of single-bucket electric shovel (or hydraulic excavator) + truck + semi-fixed crushing station + belt conveyor. The development trend of open-pit coal mining is continuous mining process, and ultimately realizes few people and unmanned open-pit mining.

[0003] With the emphasis and development of continuous mining process of open-pit coal mine, the rehandling unit begins to be applied to the continuous mining process of open-pit coal mine. Its arrangement position is generally behind the mining equipment (open-pit coal mining machine), and its function is to receive the coal material of the mining equipment and transport it to the belt conveyor device. Therefore, the rehandling unit needs to be able to move flexibly with the mining equipment, and at the same time, it needs to be able to connect with the belt conveyor device in time to achieve timely receiving and unloading. Due to the hardness of the coal seam, the mined coal material may have the problems of too large lump size and uneven size. Large coal material may cause low transportation efficiency of coal material transportation and serious damage to the conveying device, etc. Therefore, a crushing device is needed to crush again before transportation. However, if the crushing device is arranged on the coal mining machine, it will affect the coal mining efficiency of the coal mining machine and also affect the crushing effect. At present, most of the rehandling units do not have a structure with a crushing device, and there are still the following problems:
