Description

Technical Field

[0001] This invention relates to the technical field of coal mining machines, specifically to an auxiliary coal loading device for a thin coal seam coal mining machine. Background Technology

[0002] Coal mining machines are one of the key pieces of equipment for realizing the mechanization and modernization of coal mine production. Using coal mining machines can greatly reduce physical labor and improve safety. During coal mining, a scraper conveyor transports the mined coal out, and hydraulic supports support the working space to ensure smooth mining and transportation. The coal mining machine is supported and slides on the scraper conveyor via four sliding shoes, enabling it to move underground. The rocker arm transmits power to the drum, driving it to rotate at high speed to cut the coal seam.

[0003] When the coal mining machine travels along the working face on the scraper conveyor, it completes coal dropping and loading with the help of the spiral blades and cutting teeth on the drum. However, due to the low mining height and small drum diameter of thin coal seam mining machines, when the drum adopts the conventional method of reverse external rotation for coal mining and loading, the coal loading opening under the rocker arm is very small, making it difficult to load the dropped coal onto the scraper conveyor, resulting in poor loading efficiency. Furthermore, the main function of the coal mining machine's drum is to cut the coal seam, and the rocker arm is the strong arm supporting the 12-ton drum. Since the two drums move in the same direction during operation, their excessive weight can cause the coal mining machine to lose balance or even overturn, resulting in instability. Summary of the Invention

[0004] The present invention mainly provides an auxiliary coal loading device for thin coal seam mining machines to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A coal loading auxiliary device for a thin coal seam mining machine includes a mining machine and a scraper conveyor. The scraper conveyor is located at the bottom of the mining machine. Rocker arms are connected to both ends of the mining machine. A roller is connected to the side of the rocker arm near the outer wall. An auxiliary coal loading mechanism is connected to the outer wall of the rocker arm away from the roller. A buffer coal loading mechanism is provided on the scraper conveyor near the auxiliary coal loading mechanism.

[0007] Preferably, the bottom of the coal mining machine is connected to sliding shoes, and the coal mining machine is slidably connected to the scraper conveyor through the sliding shoes.

[0008] Preferably, the auxiliary coal loading mechanism includes an auxiliary coal loading base plate, and an auxiliary coal loading side plate is connected to the outer wall of the auxiliary coal loading base plate on the side away from the rocker arm. One end of the outer wall of the auxiliary coal loading side plate is fixedly connected to the rocker arm.

[0009] Preferably, the buffer coal loading mechanism includes a buffer coal loading baffle, and a stabilizing component is connected to the outer wall of the buffer coal loading baffle on the side away from the coal mining machine. The bottom of the buffer coal loading baffle is connected to the top of the scraper conveyor on one side.

[0010] Preferably, the stabilizing component includes a stabilizing frame, and several stabilizing frames are evenly arranged. The stabilizing frames are arranged in an L-shape. A stabilizing rod is connected to the bottom of the stabilizing frame near the outer wall. The stabilizing frame is welded to the outer wall of the buffer coal loading baffle, and the stabilizing rod is connected to the outer wall of the scraper coal conveyor.

[0011] Preferably, the auxiliary coal loading bottom plate and the auxiliary coal loading side plate are spliced ​​together to form an L-shaped coal loading hopper, which is connected to the outer wall of one side of the rocker arm at a 30-degree angle.

[0012] Preferably, the auxiliary coal loading mechanism is located directly above the center of the scraper conveyor.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In view of the problems in the background technology, this application provides an auxiliary coal loading mechanism. The auxiliary coal loading mechanism is located directly above the middle of the scraper conveyor. After the drum coal is mined, the coal falls onto the auxiliary coal loading bottom plate. The auxiliary coal loading side plate provides buffering. The auxiliary coal loading bottom plate and the auxiliary coal loading side plate are spliced ​​together to form an L-shaped coal hopper, which is connected to the outer wall of one side of the rocker arm at a 30-degree angle. This allows the collected coal to fall onto the scraper conveyor for transportation through the auxiliary coal loading bottom plate.

[0015] 2. By installing a buffer coal charging baffle on one side of the outer wall of the scraper conveyor, coal is prevented from falling through the auxiliary coal charging bottom plate and splashing out onto the scraper conveyor, so that the coal falls accurately onto the scraper conveyor.

[0016] 3. By setting an auxiliary coal loading mechanism on the outer wall of the rocker arm away from the drum, it is convenient to load coal. On the other hand, it increases the weight on the outer wall of the rocker arm away from the drum, preventing the two drums of the coal mining machine from moving in the same direction. Excessive weight can cause the coal mining machine to lose balance or even overturn, resulting in instability.

[0028] It should be noted that in this embodiment, auxiliary coal loading is performed by setting an auxiliary coal loading mechanism 3. The auxiliary coal loading mechanism 3 is located directly above the middle of the scraper conveyor 2. After the drum 13 collects coal, the coal falls onto the auxiliary coal loading bottom plate 31. The auxiliary coal loading side plate 32 provides buffering. The auxiliary coal loading bottom plate 31 and the auxiliary coal loading side plate 32 are spliced ​​together to form an L-shaped coal loading bucket, which is connected to the outer wall of one side of the rocker arm 12 at a 30-degree angle, so that the collected coal falls onto the scraper conveyor 2 through the auxiliary coal loading bottom plate 31 for transportation.

[0029] Furthermore, by setting a buffer coal loading baffle 41 on one side of the outer wall of the scraper conveyor 2, coal is prevented from falling through the auxiliary coal loading bottom plate 31 and splashing out onto the scraper conveyor 2, so that the coal falls accurately onto the scraper conveyor 2.

[0030] Furthermore, by setting an auxiliary coal loading mechanism 3 on the outer wall of the rocker arm 12 away from the drum 13, it is convenient to load coal on the one hand, and on the other hand, it increases the weight on the outer wall of the rocker arm 12 away from the drum 13 to prevent the two drums 13 of the coal mining machine 1 from moving in the same direction.

The outer wall of plate 41 is welded together, and the stabilizing rod 52 is connected to the outer wall of scraper conveyor 2 for use; auxiliary coal loading is carried out by setting an auxiliary coal loading mechanism 3, which is located directly above the middle of scraper conveyor 2. After the drum 13 collects coal, the coal falls onto the auxiliary coal loading bottom plate 31, and the auxiliary coal loading side plate 32 provides buffering. The auxiliary coal loading bottom plate 31 and the auxiliary coal loading side plate 32 are spliced ​​together to form an L-shaped coal loading hopper, which is connected to the outer wall of one side of the rocker arm 12 at a 30-degree angle, so that the collected coal falls onto the scraper conveyor 2 through the auxiliary coal loading bottom plate 31 for transportation;

[0033] By setting a buffer coal loading baffle 41 on one side of the outer wall of the scraper coal conveyor 2, coal is prevented from falling through the auxiliary coal loading bottom plate 31 and splashing out onto the scraper coal conveyor 2, so that the coal falls accurately onto the scraper coal conveyor 2.

[0034] By setting an auxiliary coal loading mechanism 3 on the outer wall of the rocker arm 12 away from the drum 13, it is convenient to load coal. On the other hand, it increases the weight on the outer wall of the rocker arm 12 away from the drum 13, preventing the two drums 13 of the coal mining machine 1 from moving in the same direction. Excessive weight would cause the coal mining machine 1 to lose balance or even overturn, resulting in instability.
