Description

Coal mining transmission device

technical field

The utility model relates to the technical field of coal mining transmission, in particular to a coal mining transmission device.

Background technique

After mining, coal mines usually need to use transmission equipment to transport the mined coal to the storage site for centralized management. However, during the mining process of the coal mine, some relatively large coal blocks are usually entrained, and the larger coal blocks need to be sorted out for processing. Crushing treatment, and the crushing and transportation of coal blocks are often carried out separately, resulting in the need to sort and crush large coal blocks after transportation, which increases the working hours;

A coal mining transmission device disclosed in the prior art (publication number: CN216025115U) includes a base, and the top of the base is fixedly connected with a first conveyor belt through a fixing piece. The utility model relates to the technical field of coal mining transmission. In this coal mining transmission device, a filter screen plate is set inside the fixed frame, so that the large coal block can be separated from the small coal block, and the large coal block can also be rolled down through the inclined setting of the filter screen plate The crushing process is carried out on the upper part of the crushing drum. In this way, the coal block can be sorted and crushed while the coal block is being transported, thereby improving the work efficiency. The worm is set so that the first rotating shaft drives the crushing drum to roll and roll, and at the same time, the cooperation between the worm and the worm wheel can make the filter screen reciprocate and sieve, so as to avoid the problem of blockage of the filter screen due to long-term use However, when the device is in use, large pieces of coal can be separated from small pieces of coal through the screen plate, wherein the screen plate reciprocates and sieves. When solid objects such as ores are stuck in it, if the depth of the card It is deeper, and when there are other fixed objects in the upper part, it is difficult to vibrate the solid objects in the sun, and they will be resisted by the solid objects in the upper part, making it still difficult to clean up the blockage, resulting in reduced practicability.
