Description

Technical Field

[0001] The invention belongs to the technical field of coal mine transportation, and in particular relates to a belt conveyor device used in coal mine mining. Background Art

[0002] Coal mining is the process of mining coal resources in coal-rich areas. These are generally classified as underground and open-pit mines. When the coal seam is far from the surface, tunnels are typically excavated underground, creating an underground mine. When the coal seam is close to the surface, the coal is extracted directly from the surface soil, creating an open-pit mine. The vast majority of coal mines in my country are underground. Coal mines encompass large areas above and below ground, including related facilities. Coal mines are the natural spaces humans create when digging coal-rich strata, typically consisting of tunnels, shafts, and mining faces. Coal is the primary solid fuel and a type of combustible organic rock. It is formed by lush vegetation that thrives over a certain geological age, gradually accumulating into thick layers in a suitable geological environment and then being buried under water or in mud. This process, known as natural coalification, occurs over a long period of time. Conveyors are essential for coal mining. Existing conveyors have unstable drop points, and because the belts are unevenly stressed, they can cause the belts to deviate and lead to serious accidents. Furthermore, when material falls directly onto the belts, the inertia and weight of the material collide with them, damaging them and shortening their service life. Therefore, addressing these issues is crucial. Summary of the Invention

[0003] The present invention overcomes the deficiencies of the prior art and provides a belt conveyor device for coal mining, which can prevent the belt from deviating, prolong the service life of the belt and facilitate adjustment of the position of the material dropping point.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

One of the fixed shafts is connected to the extension shaft, and a shaft cap is provided at the end of the extension shaft. A pressure sleeve is sleeved on the extension shaft, and the circumferential surface of the pressure sleeve is fixedly connected to an arc segment positioning body near the top position, and the arc segment positioning body has arc segment teeth built in, and the arc segment teeth can mesh with the gears. A return spring is sleeved on the extension shaft between the pressure sleeve and the shaft cap, and a swing handle is hinged on the side of the shaft cap, and the middle part of the swing handle is connected to the pressure sleeve, and the pressure sleeve can be driven to slide on the extension shaft by rotating the swing handle.

[0006] A further improvement of the present invention is that the fixed shaft and the extension shaft are integrally formed.

[0007] A further improvement of the present invention is that the diameter of the shaft cap is larger than the diameter of the extension shaft.

[0008] A further improvement of the present invention is that the movable seat is in an n shape.

The T-slot 7 extends along the conveying direction of the belt 2, and a T-block 8 is provided on the movable seat 4 between the contact surface of the movable seat 4 and the fixed seat 3. The T-block 8 is placed in the T-slot 7. Fixed shafts 9 are evenly distributed near the top position on the side of the movable seat 4, and gears 10 are provided on the fixed shafts 9 for rotation. The gears 10 mesh with racks 11. 11 is fixedly installed on the top of the fixed seat 3, one of the fixed shafts 9 is connected to the extension shaft 12, and a shaft cap 13 is provided at the end of the extension shaft 12. A pressure sleeve 14 is sleeved on the extension shaft 12, and key grooves 15 are evenly distributed on the extension shaft 12 between the pressure sleeve 14 and the contact surface of the extension shaft 12. Parallel keys 16 are evenly distributed on the pressure sleeve 14 between the pressure sleeve 14 and the contact surface of the extension shaft 12. The parallel keys 16 are placed in the key grooves 15, and the circumferential surface of the pressure sleeve 14 is fixedly connected to the arc segment positioning body near the top position. The arc segment positioning body has arc segment teeth 18 built in, and the arc segment teeth 18 can engage with the gear 10. A return spring 19 is sleeved on the extension shaft 12 between the pressure sleeve 14 and the shaft cap 13, and a swing handle 20 is hinged on the side of the shaft cap 13.
