Description

Technical Field

[0001] This utility model belongs to the field of coal mine equipment, and in particular relates to a coal blocking device at the junction of belt conveyor and scraper conveyor when the roadway height is low. Background Technology

[0002] In underground coal mines, it's common to see 40T, 150T, and 180T scraper conveyors interlocked with belt conveyors. Due to complex mine geological conditions, the roadway height often doesn't allow for laying the belt conveyor at the working face to interlock with the system belt. Laying it directly would result in insufficient auxiliary transport height, affecting transport. In such cases, a scraper conveyor needs to be laid across the auxiliary transport track to reduce workload and ensure auxiliary transport. Therefore, in a newly installed 21512 working face of a certain mine, a belt conveyor was interlocked with a 730 scraper conveyor. Using the existing coal blocking device, spillage was severe. Even slightly large volumes of coal could bury the reducer and motor, requiring dedicated personnel for cleanup. Furthermore, spray water and coal dust directly flowed into or splashed onto the motor and reducer surfaces, reducing equipment lifespan. Utility Model Content

[0003] The purpose of this utility model is to provide a coal blocking device at the junction of the belt conveyor and the scraper conveyor when the roadway height is low, so as to solve the problem that the reducer and motor are buried due to a slightly large cargo volume at the junction of the belt conveyor and the scraper conveyor when the roadway height is low.

[0004] This utility model adopts the following technical solution: a coal-blocking device at the junction of the belt conveyor and the scraper conveyor when the roadway height is low, comprising: The first inclined baffle is inclined, with its lower end abutting against the left side of the scraper conveyor and its upper end extending away from the scraper conveyor. A horizontal baffle is set horizontally. One end of the baffle is fixedly connected to the upper end of the first inclined baffle, and the other end extends away from the scraper machine. The lower side of the baffle is used to place the reduction motor of the scraper machine. The horizontal baffle is used to block dust and water falling towards the reduction motor. The second inclined baffle is inclined and its lower end abuts against the right side of the scraper conveyor, while its upper end extends away from the scraper conveyor. The second inclined baffle is symmetrically arranged with the first inclined baffle. The first and second inclined baffles are both installed at the receiving end of the scraper conveyor; the scraper conveyor transports materials from back to front. Also includes: A soft rubber sheet, the rear end of which is fixedly connected to the front end of the second inclined baffle, and the front end of which extends forward and is aligned with the front end of the first inclined baffle; The first and second inclined baffles are used to collect materials and prevent spillage. The soft rubber plate is used to bend downwards when materials are piled up, so that the materials piled on it collapse downwards and fall into the container located on the floor of the tunnel below, preventing materials from spilling from the front end of the first inclined baffle and submerging the geared motor.

[0005] The beneficial effects of this utility model are: This invention can prevent the geared motor from being buried by materials or spilled goods, reduce manual cleaning, reduce labor intensity, and greatly improve the service life of the equipment. This utility model, by setting a first inclined baffle and a second inclined baffle, can accommodate a larger volume of goods. During the continuous forward transport of goods by the scraper conveyor, goods that cannot be transported in time are unloaded from the soft rubber plate, thereby preventing materials from spilling onto the side of the first inclined baffle. The materials fall directly into the container located on the floor of the tunnel below, preventing materials from spilling from the front end of the first inclined baffle and submerging the reduction motor.

[0010] This utility model discloses a coal-blocking device at the junction of the belt conveyor and the scraper conveyor when the roadway height is low, such as... Figure 1 and Figure 2 As shown, it includes: a first inclined baffle 10, a horizontal baffle 11, and a second inclined baffle 12.

[0011] The first inclined baffle 10 is inclined, with its lower end abutting against the left side of the scraper conveyor 13, and its upper end extending away from the scraper conveyor 13.

[0012] The horizontal baffle 11 is set horizontally. One end of the horizontal baffle 11 is fixedly connected to the upper end of the first inclined baffle 10. The other end of the horizontal baffle 11 extends away from the scraper machine 13. The lower side of the horizontal baffle 11 is used to place the reduction motor of the scraper machine 13. The horizontal baffle 11 is used to block dust and water falling towards the reduction motor.

[0013] The second inclined baffle 12 is inclined, with its lower end abutting against the right side of the scraper conveyor 13, and its upper end extending away from the scraper conveyor 13. The second inclined baffle 12 is symmetrically arranged with the first inclined baffle 10.

[0014] The first inclined baffle 10 and the second inclined baffle 12 are both installed at the receiving end of the scraper conveyor 13; the scraper conveyor 13 transports materials from back to front.

[0015] The present invention also includes: a soft rubber plate 14, the rear end of which is fixedly connected to the front end of the second inclined baffle 12, the front end of which extends forward and is aligned with the front end of the first inclined baffle 10.

[0016] The first inclined baffle 10 and the second inclined baffle 12 are used to collect materials and prevent spillage. The soft rubber plate 14 is used to bend downward when materials are piled up, so that the materials piled on it collapse downward and fall into the container located on the roadway floor below, preventing materials from spilling from the front end of the first inclined baffle 10 and submerging the reduction motor.

[0017] The outer sides of the first inclined baffle 10 and the second inclined baffle 12 are both covered with fixed plates 15 parallel to them. The first inclined baffle 10 and the second inclined baffle 12 are both fixedly connected to the fixed plates 15. The fixed plates 15 are fixedly connected to the upper end of the vertically arranged positioning plate 16. The lower end of the positioning plate 16 is fixedly connected to the groove side of the scraper machine 13. The positioning plate 16 is used to position and support the first inclined baffle 10 and the second inclined baffle 12 through the fixed plates 15.

[0018] The present invention also includes a pull rod 17, which is located between the first inclined baffle 10 and the second inclined baffle 12. The two ends of the pull rod 17 are fixedly connected to the inner sides of the first inclined baffle 10 and the second inclined baffle 12, respectively. The pull rod 17 is used to pull the first inclined baffle 10 and the second inclined baffle 12 to prevent the first inclined baffle 10 and the second inclined baffle 12 from expanding outward.

[0019] The rear ends of both the first inclined baffle 10 and the second inclined baffle 12 extend into the underside of the upper belt of the belt conveyor. Only in this way can all the material at the unloading point of the belt conveyor be received. Otherwise, although it can prevent the material from spilling onto the front end of the first inclined baffle 10, if the rear end of the first inclined baffle 10 is not blocked, the reduction motor will still be buried from the rear end of the first inclined baffle 10. Therefore, extending the rear ends of both the first inclined baffle 10 and the second inclined baffle 12 into the underside of the upper belt of the belt conveyor can prevent this situation from occurring.

[0020] The front-to-back length of the first inclined baffle 10 is greater than the front-to-back length of the second inclined baffle 12. Preferably, the front-to-back length of the first inclined baffle 10 is equal to the sum of the front-to-back length of the second inclined baffle 12 and the front-to-back length of the soft rubber sheet 14.

[0021] The length of the second inclined baffle 12 is limited because if the length of the second inclined baffle 12 is set to be greater than that of the first inclined baffle 10, the material will fall towards the side of the first inclined baffle 10. Therefore, the length of the first inclined baffle 10 is set to be longer, while the length of the second inclined baffle 12 is set to be shorter. This ensures that when a large amount of material arrives, if the scraper conveyor 13, the first inclined baffle 10, and the second inclined baffle 12 cannot temporarily receive it, the material can be spilled from the side of the second inclined baffle 12, which is convenient for cleaning and also avoids burying the reduction motor 18. Example

[0022] The newly installed 21512 mining face of a certain mine connects the belt conveyor with the 730 scraper conveyor. Using the old coal blocking device, the spillage is quite serious. If the amount of cargo is slightly large, the reducer and motor will be buried. At the same time, it is necessary to arrange special personnel to clean up the cargo. In addition, the spray water and coal dust directly flow into or sprinkle onto the surface of the motor and reducer, reducing the service life of the equipment.

[0023] The materials required to prepare this utility model are shown in the table below.

[0024] Manufacturing method: Using the square bolt holes on both sides of the tail trough plate of the 730 scraper conveyor as a reference, two steel plates with a thickness of 8mm and a length of 3m × 2.6m are used to make the first inclined baffle 10 and the second inclined baffle 12. The holes of the positioning plate 16 are set according to the corresponding holes at the tail of the chute. The horizontal baffle 11 is a steel plate with a length of 3m and a width of 0.4m. The horizontal baffle 11 is welded to the first inclined baffle 10 to prevent spray water, coal dust and other debris from damaging the reducer and motor. After the two steel plates are processed in the above manner, the angle between the first inclined baffle 10 and the second inclined baffle 12 and the vertical direction is 30°.

[0025] After installing this utility model, the driver's time for clearing goods is saved each shift, which is expected to save 2 hours of working time per shift, about 200 yuan per shift. At the same time, it extends the service life of the equipment. More than 400 meters of this working face has been excavated, and there has been no failure of burying the reduction motor 18.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
