Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment technology, specifically to a follow-up coal collection scraper conveyor. Background Technology

[0002] A coal mine is an area where humans extract coal resources in coal-rich areas, generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, underground tunnels are typically dug to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is typically stripped away to extract the coal; this is called an open-pit coal mine. A coal mine encompasses a large area, including both above-ground and underground sections, as well as related facilities. A coal mine is a rationally excavated space created by humans when mining coal-rich geological strata, typically including tunnels, shafts, and working faces. Coal is the most important solid fuel and a type of combustible organic rock. It is formed from abundant vegetation that grew in a specific geological era, gradually accumulating into thick layers under suitable geological conditions, buried underwater or in silt, and undergoing natural coalification over long geological periods. Among the world's geological periods, the Carboniferous, Permian, Jurassic, and Tertiary strata contain the most coal and are considered important coal-forming eras.

[0003] A publicly available patent (publication number CN206361155U) discloses a follow-up coal collection scraper conveyor, including an upper connecting bayonet, a lower connecting bayonet, and a cover. The upper opening of the cover is closedly connected to the upper connecting bayonet, and the lower opening of the cover is closedly connected to the lower connecting bayonet. This coal collection conveyor, while meeting product sealing requirements, can accommodate ball joints with a larger swing angle, improve the tear resistance of the cover's closing end, and effectively extend the service life of the dust cover without frequent replacement, thereby reducing vehicle maintenance costs. However, existing coal collection scraper conveyors have some problems in use: 1. When using existing coal collection scraper conveyors on the market, coal tends to accumulate excessively during operation, leading to difficulties in smooth conveying and reducing overall project progress; 2. The operating principle of existing coal collection scraper conveyors is relatively complex, making them inconvenient for efficient and convenient use, thus reducing the overall scope of their widespread application. Utility Model Content

[0004] The purpose of this invention is to provide a follow-up coal collection scraper conveyor to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a follow-up coal collection scraper conveyor, including a drive motor, a scraper conveyor and a collection and cleaning assembly disposed on the surface of the machine body; The output shaft of the drive motor is connected to the input end of the gearbox, and the output end of the gearbox is connected to the drive roller. The drive roller is located at one end of the machine body and has two sprockets. There are two chains, which are wrapped around the surfaces of the sprockets respectively. A scraper is installed between the chains. A discharge port is provided at one end of the drive roller. A driven roller is connected to the other end of the machine body. Two sprockets are installed on the surface of the driven roller. A chute is connected to the surface of the driven roller. A pair of chain pressure plates are detachably connected to the surface of the chute. A guard plate is detachably connected to one side of the machine body. A coal retainer plate is detachably connected to the lower part of the other side of the machine body. A collection and cleaning component is detachably connected to one side of the machine body, and a track is detachably connected to the machine body; the collection and cleaning component moves laterally along the track.

[0006] As a further improvement of this utility model, the collection and cleaning component also includes a collection groove, which is an inclined groove, and coal cleaning plates are provided on both sides of the surface of the collection and cleaning component.

[0007] As a further embodiment of this utility model: the collection and cleaning component is internally connected to a motor frame, with two small motors mounted on the motor frame. The motor frame has a "U" shaped structure. The output shafts of the small motors are connected to the small pulleys via a key. The large pulley and the small pulleys are connected by a belt. The large pulley is connected to a roller via a shaft.

[0008] As a further improvement of this utility model, the coal retaining plate is located above the track and parallel to the track.

[0009] As a further improvement of this utility model: an L-shaped groove is provided on one side of the collection and cleaning component, and a guide groove is provided on the surface of the body, with one end of the L-shaped groove embedded in the guide groove.

[0010] As a further improvement of this utility model: the drive motor is a three-phase explosion-proof motor, the two sprockets on the drive drum are fixedly connected to the drive drum, and the two sprockets on the driven drum are fixedly connected to the driven drum.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. At the start of coal mining operations, the machine body is a scraper conveyor. The drive motor transmits power to the gearbox, which in turn transmits amplified torque to the drive drum. The drive drum drives the chain and scraper to move. Then, the coal mining machine moves along the track on the scraper conveyor. The coal mining machine is responsible for stripping the coal seam off, and the coal chunks falling onto the chute are moved to the next designated position by the scraper. At the same time, the collection and cleaning component moves along the track and follows behind the coal mining machine. Through the collection trough on it, it transports the coal chunks that have not fallen onto the chute to the chute. The collection and cleaning component moves laterally... The conveyor moves back, pushing the coal into the collection trough. This curved collection trough then sends the coal into the upper chute, thus cleaning up the coal in front of the scraper conveyor and facilitating further movement. It retains the original overall structure of the traditional scraper conveyor, with a collection and cleaning component added to the existing structure. The main function of this component is to move the coal accumulated in front of the scraper conveyor onto the chute, reducing the obstruction caused by coal and making the conveyor's movement smoother, avoiding situations where it is stuck and unable to move due to coal blockage.

[0012] 2. In use, this utility model facilitates the passage of coal blocks through scrapers between chains, and discharges the coal blocks through a discharge port at one end of the drive roller. The other end of the machine body is connected to a driven roller, which rotates two detachably connected sprockets on its surface. This, in turn, moves the chute connected to the driven roller and a pair of detachably connected chain plates, thus conveying the coal blocks. Guard plates prevent the coal blocks from falling. The design principle is simple and reliable, and its collection and cleaning components have a simple structure, are easy to install, and have broad application prospects.

[0017] Example 2: In addition to all the technical features in Example 1, this example also includes: the collection and cleaning component 14 further includes a collection groove 1401, which is an inclined groove; coal cleaning plates 1408 are provided on both sides of the surface of the collection and cleaning component 14; a motor frame 1403 is connected inside the collection and cleaning component 14; two small motors 1402 are mounted on the motor frame 1403, which has a "U" shaped structure; the output shaft of the small motor 1402 is connected to the small pulley 1406 via a key; the large pulley 1404 and the small pulley 1406 are connected by a belt 1405; the large pulley 1404 is connected to the roller 1409 via a shaft; during use, the motor drives the small pulley 1406 connected to its output end to rotate; the small pulley 1406 drives the large pulley 1404 to rotate via the belt 1405; and the large pulley 1404 drives the roller 1409 to rotate via the shaft.

[0018] The coal retaining plate 10 is located above the track 12 and parallel to the track 12. An L-shaped groove 1407 is provided on one side of the surface of the collection and cleaning component 14, and a guide groove 11 is provided on the surface of the body 16.

The guard plate 8 prevents the coal blocks from falling. The design principle is simple and reliable, and its collection and cleaning components have a simple structure, are easy to install, and have broad application prospects.
