Description

Technical Field

[0001] The utility model relates to the field of coal mine excavation, in particular to a transportation device for coal mine excavation. Background Art

[0002] A coal mine is an area where humans exploit coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when digging geological strata rich in coal. They usually include tunnels, shafts, mining faces, etc. Coal is the most important solid fuel and a type of combustible organic rock.

[0003] According to a coal mine transportation device for coal mine excavation disclosed in the national patent network (authorization announcement number: CN216548270U), "the utility model discloses a coal mine transportation device for coal mine excavation, which belongs to the technical field of coal mine transportation devices. The key points of its technical solution include a frame, a conveyor belt is arranged on the inner wall of the frame, a buffer box is fixedly connected to the inner wall of the frame, two holes are opened at the bottom of the buffer box, a feed hopper is fixedly connected to the top of the buffer box, and the bottom of the feed hopper extends to the inside of the buffer box. The utility model can separate larger coal blocks and smaller coal blocks through a leak plate by arranging a separation device, so that smaller coal blocks and larger coal blocks can be transported to the conveyor belt at the same time through different routes, thereby improving production efficiency; by arranging an energy absorption device, a part of the gravity of the falling coal blocks can be absorbed, so that the coal blocks will not cause damage to the conveyor belt when they fall on the conveyor belt, thereby improving the service life of the conveyor belt, reducing the cost of maintaining the conveyor belt, and improving production efficiency."

[0004] The device is equipped with a buffer box to classify and transport coal blocks, which improves the service life of the conveyor belt to a certain extent. However, coal is a combustible substance. When coal is rubbed, squeezed or affected by high temperature on the conveyor belt, there may be a risk of combustion or spontaneous combustion. The device is not equipped with relevant mechanisms, and the fire risk is relatively high. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a transport device for coal mine excavation. The device is provided with a sprinkler mechanism to avoid excessively high temperatures and dry environments, which helps to reduce the risk of fire.

[0006] A transportation device for coal mining, comprising a frame, a conveyor belt is arranged on the top of the frame, side rollers are fixedly connected to both sides of the conveyor belt, a motor is arranged on the surface of the frame, a scraping mechanism is arranged below the conveyor belt, the scraping mechanism comprises a cross bar, the cross bar is fixedly connected to the lower part of the frame, a buffer mechanism is arranged at one end of the conveyor belt, the buffer mechanism comprises a chute, the chute is fixedly connected to one end of the frame, a sprinkler mechanism is arranged on the top of one end of the frame close to the buffer mechanism, the sprinkler mechanism comprises a water tank, a pipe is arranged at one end of the water tank close to the conveyor belt, a fixed block is fixedly arranged at one end of the pipe away from the water tank, the fixed block is fixedly connected to one end of the chute close to the conveyor belt, a nozzle is arranged on the surface of the fixed block, a conduction chain is arranged at one end of the frame away from the buffer mechanism, and the nozzle can be adjusted so as to better wet the coal transported on the conveyor belt.

[0007] The above technical solution further includes:

[0008] The scraping mechanism also includes a sliding wheel, which is arranged on the surface of the horizontal bar. A collection box is arranged on the top of the sliding wheel. A scraper is arranged on the surface of one end of the collection box close to the buffer mechanism. The scraper can be rotated and adjusted to prevent damage to the device caused by overly stubborn attachments. A handle is arranged on the side of the collection box to facilitate its dumping.

[0009] The buffer mechanism also includes a feed box, which is fixedly connected to the end of the chute away from the conveyor belt. An elastic plate is provided at the inner bottom of the feed box, a damping column is fixedly connected to the bottom of the elastic plate, a shock-absorbing column is fixedly connected to the bottom of the feed box, and a conveying wheel is provided at the end of the chute away from the feed box. The use of the damping column and the shock-absorbing column greatly reduces the damage to the device when the coal falls, and improves the service life of the device. At the same time, the output wheel is provided to slightly slow down the coal before it slides down the chute to the conveyor belt, so as to reduce the damage of the coal to the conveyor belt.

[0010] The water tank, the pipe, the fixing block and the nozzle are in two groups and are symmetrically distributed about the slide slot.

[0011] There are multiple groups of sliding wheels evenly arranged at the bottom of the collection box. The sliding wheels are arranged to facilitate taking out the collection box after the operation is completed and to handle the scraped attachments.

[0012] There are multiple shock-absorbing columns evenly distributed at the bottom of the feed box, the size and position of the elastic plate correspond to the size and position of the opening of the feed box, and there are multiple damping columns evenly distributed below the elastic plate.

[0013] Beneficial effects:

[0014] 1. The excavation transport mechanism is equipped with a sprinkler mechanism. When the coal is transported to the device, the sprinkler mechanism is started to realize humidification and dust removal throughout the process. By humidifying the coal surface and the air nearby, the dryness of the air is reduced and the generation of static electricity is reduced. On the other hand, humidification can reduce the concentration of coal dust in the air and prevent coal dust from accumulating to form a thin layer or even clogging the equipment. At the same time, since dry coal dust is prone to friction, it increases the resistance of the conveyor belt and reduces the conveying efficiency. By changing the humidity in the air through humidification, friction can be reduced and the operating efficiency of the conveyor belt can be improved.

[0015] 2. The excavation transport mechanism is equipped with a buffer mechanism and a scraping mechanism. The buffer mechanism can reduce the impact force and friction of the coal, reduce the degree of wear, extend the service life of the conveyor belt and conveying machinery, achieve smooth transmission, and improve the stability of the operation. At the same time, a scraping mechanism is set to effectively remove the coal, dust and other impurities remaining on the conveyor belt to prevent these materials from re-accumulating, scattering or clogging the equipment during transportation. At the same time, it can also reduce friction and reduce the resistance of the conveyor belt, thereby improving the throughput and energy efficiency of the conveyor, realizing self-cleaning of the conveyor belt, and saving cleaning procedures and labor.
