Description

A ore layer cutting and falling device used in coal mining

Technical Field

The invention relates to the technical field of ore layer cutting, and more specifically, to an ore layer cutting and dropping device used in coal mining.

Background technique

Coal mines refer to places rich in coal resources, which are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal, which is an underground coal mine; when the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal, which is an open-pit coal mine; after the topsoil of the open-pit coal mine is removed, the ore layer will be exposed, and at this time, various mechanical equipment is needed for mining operations;

In order to improve the mining efficiency of open-pit coal mines, reduce the labor intensity of workers, and adapt to complex environments, cutting equipment is often used in mining operations to cut and separate the ore layers;

After checking the publication (announcement) number: CN112855135B, a coal cutting device with adjustable distance for coal mining is disclosed. This technology discloses "a coal cutting device with adjustable distance for coal mining, including a base lifting platform and a box body, the lifting platform is connected to the top of the base, the bottom of the box body is provided with an angle adjustment component, the box body is connected to the top of the lifting platform through the angle adjustment component, the top of the box body is provided with a dust removal component, the inside of the box body is provided with a distance adjustment mechanism and other technical solutions, and has the function of bidirectional clamping and cutting of coal seams, greatly improving the cutting efficiency, and at the same time, the height, lateral angle and lateral distance of the cutting device can be adjusted to meet different cutting requirements and other technical effects".

However, when this device is in use, it can be seen from its structure that when its upper and lower double-layer cutting mechanism cuts the ore layer, the two sides of the cut part of the ore layer and the deep position are still connected to the ore layer, and the cut ore layer cannot be directly separated. It also needs to be assisted by explosives or external knocking equipment to form a complete cutting and mining operation. This process will undoubtedly waste a lot of time and labor cost output, affect the mining efficiency, and is not conducive to large-scale mining operations;

In order to solve the above problems, the present application proposes a ore layer cutting and dropping device used in coal mining.

When the lower cutting teeth and the circular cutting teeth cut the ore rock and move to the middle position adjacent to the cut ore rock, the side cutting teeth are used to cut the two sides of the ore rock, so that the ore rock can be conveniently cut into rectangular blocks and separated from the ore layer. Compared with the existing coal mine cutting equipment, the ore rock can be conveniently separated without external equipment and the cooperation of multiple people, which effectively reduces the cost output of coal mining operations and greatly improves the efficiency of coal mine cutting and mining operations.

After the block material is separated from the ore layer, the present invention uses a rotating seat to rotate and store the lower cutting teeth, and then uses a pull rod to hook an edge of the coal block material, and then the upper slide seat is recovered to drive the coal block material to move outward. Compared with the existing cutting and mining operations, the coal block material can be completely taken out without crushing, so that the mineral can be completely separated from the ore layer for subsequent processing and use;

After the block material is taken out, the present invention guides it into the interior of the transfer seat through the roller and the inclined roller, then lowers the lifting seat and pushes out the slide plate to drive the coal block material to slide outward, so that it falls into the external transmission equipment for transfer processing. Based on this, a complete mining operation is formed, and the integrated function of mining, separation and transfer can be formed without the cooperation of multiple machines. Compared with the existing equipment, it has more efficient mining efficiency and improves the overall practical performance of the equipment.

It can be understood that the present invention can automatically separate coal blocks from the ore layer when cutting them, and take them out for unloading, and can complete integrated and continuous operations without the need for the cooperation of multiple devices. While improving coal mining efficiency, it reduces labor and equipment cost output, and is conducive to large-scale coal mine ore layer cutting and separation operations.

The working principle and operation process of the present invention are specifically as follows:

First, the lifting platform 33 is driven to lift up and adjust the distance between the lower slide 3 and the upper slide 4, and then the spiral transmission rod inside the lifting seat 2 is driven to drive the lower slide 3 and the upper slide 4 to move outward, so as to drive the lower cutting teeth 31 and the circular cutting teeth 41 to cut the ore layer, and then when the lower cutting teeth 31 and the circular cutting teeth 41 move to the middle position near the front of the equipment, the side cutting teeth 51 are driven to cut both sides of the ore rock, and move upward to reset after cutting, and then when the lower cutting teeth 31 and the circular cutting teeth 41 cut to the predetermined position, each surface of the cut ore rock automatically separates from the ore layer, and the cutting operation is completed; further, the rotating seat 32 is driven to rotate and store the lower cutting teeth 31, and then the circular cutting teeth 41 are moved to the middle position in front of the equipment, and then the cutting teeth 51 are driven to cut the ore layer. Driving the first electric telescopic device 63 to push the transfer rod 62 can drive the front end of the pull rod 6 to be pressed down, so that 66 hooks the edge of the coal block. At this time, the lower sliding seat 3 can be directly recovered to pull the block out. Then, under the guidance of the roller 72 and the inclined roller 73, the block directly slides into the interior of the transfer seat 7 for storage. Finally, the lower sliding seat 3 is lowered and the second electric telescopic device 76 is driven to push the slide plate 71 outward to connect it to the external transmission equipment. Then, the telescopic mechanism at the upper end of the arc-shaped base 79 is driven to drive the transfer seat 7 to tilt, so that the block automatically slides under the rolling action of the transverse roller 74 to form unloading. Based on this, the complete operation of mining, separation and unloading is completed, and efficient coal mine layer cutting and mining operations can be formed without the need for external knocking equipment.
