Description

Technical Field

[0001] This utility model relates to the technical field of coal mining, and in particular to a coal retaining structure for a belt conveyor. Background Technology

[0002] Belt conveyors are crucial equipment in coal mining, serving as continuous conveying machinery for transporting coal materials. During operation, coal may spill from both sides of the belt for various reasons. Coal retainers effectively prevent this spillage, ensuring coal falls accurately into designated locations or containers, reducing waste and environmental pollution. Coal spillage can damage equipment below the conveyor, affecting its normal operation. By minimizing spillage and equipment damage, coal retainers help maintain stable conveyor operation, reducing downtime due to equipment malfunctions and coal removal, thereby improving overall coal mine production efficiency.

[0003] A conveyor belt coal retainer structure, authorized by announcement number CN221875330U, proposes a method where a pressing plate is quickly squeezed, and a connecting rod drives an insert rod downwards, causing the insert rod to move completely away from the through hole. This, combined with the connecting seat and connecting piece, facilitates the rapid flipping of the spare coal retainer, allowing it to replace the original coal retainer for continued operation. However, in practice, we have found that the coal retainer plates, after being fitted with coal retainers, occupy the effective area of ​​the conveyor belt, leading to coal accumulation at the coal drop point. Furthermore, the fixed installation method of the coal retainer plates in practice makes it impossible to clean up the accumulated coal at the drop point, thus occupying transportation space. Additionally, the method of flipping the spare coal retainer is time-consuming and labor-intensive, and the flipped plate cannot be fixed in place, causing knocking noise when coal contacts the retainer plate. Therefore, this utility model provides a conveyor belt coal retainer structure. Utility Model Content

[0004] The purpose of this application is to provide a coal retaining structure for a belt conveyor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a coal retaining plate structure for a belt conveyor, comprising a base plate, a coal retaining plate body, and a fixed coal retaining plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The shown coal retaining structure for a belt conveyor includes a base plate 10, a coal retaining plate body 20, and a fixed coal retaining skin 30. The base plate 10 has a T-shaped groove 11, and a T-shaped slider 13 is slidably connected in the T-shaped groove 11. The base plate 10 is connected to the coal retaining plate body 20 through the T-shaped slider 13. An adjusting plate 12 is installed on the side of the coal retaining plate body 20 near the base plate 10. The adjusting plate 12 is provided with an adjusting component for adjusting the position of the coal retaining plate body 20, and the adjusting component includes an adjusting frame 40 embedded in the adjusting plate 12.

[0024] A fixed coal retaining plate 30 is fixedly installed on the bottom side of the coal retaining plate 20 away from the base plate 10 by bolts. Fixed sliding grooves 21 are opened at both ends of the coal retaining plate 20. Fixed sliders 22 are slidably connected to the coal retaining plate 20 in the fixed sliding grooves 21. The fixed sliders 22 are connected to spare coal retaining plates 24 through L-shaped connecting rods 23. The spare coal retaining plates 24 block and replace the fixed coal retaining plates 30.

[0025] See Figure 1 , Figure 2 and Figure 3 A rotating shaft 25 is fixedly installed on the top of the coal retaining plate 20 by bolts. A rotating baffle 26 is fixedly installed on the rotating shaft 25. An arc-shaped rotating groove 27 is opened on the side of the spare coal retaining plate 24 near the base plate 10. The top of the rotating baffle 26 is movably engaged in the arc-shaped rotating groove 27. The rotation of the rotating baffle 26 and the arc-shaped rotating groove 27 are coordinated to support the lifting and lowering of the spare coal retaining plate 24.

[0026] The spare coal retaining sheet 24 is movable on the outside of the fixed coal retaining sheet 30. The spare coal retaining sheet 24 is the same size as the fixed coal retaining sheet 30 and their positions overlap. The spare coal retaining sheet 24 is used to replace the fixed coal retaining sheet 30 that falls in an emergency, so as to avoid affecting the normal transportation and production of the belt conveyor and improve the working efficiency of coal mine production operations.

[0027] See Figure 3 , Figure 4 and Figure 5 Several telescopic springs 41 are fixedly installed on the inner top of the adjusting frame 40 by bolts. A positioning plate 42 is fixedly installed between the bottom ends of the telescopic springs 41 by bolts. Positioning blocks 43 are fixedly installed at both ends of the bottom of the positioning plate 42 by bolts. A rubber support pad 44 is fixedly installed at the bottom end of each positioning block 43 by bolts. The rubber support pad 44 under the positioning block 43 makes stable and effective contact with the friction pad 47 in the groove 46, so that the positioning block 43 can be fixedly supported at any position in the groove 46.

[0028] A U-shaped handle 45 is bolted to the top of the positioning plate 42, and the top of the U-shaped handle 45 extends through to the outer side of the top of the adjusting frame 40. A groove 46 is provided on the top of the base plate 10, and a rubber friction pad 47 is bolted to the groove 46 on the base plate 10. The rubber support pad 44 and the friction pad 47 move against each other. The adjusting frame 40 moves to one side of the top of the base plate 10, and the U-shaped handle 45 moves to the top of the adjusting frame 40. The state of the positioning plate 42 and the telescopic spring 41 is controlled by the U-shaped handle 45 to adjust the position of the coal retaining plate 20 on the base plate 10.

[0029] The working principle of this utility model is as follows: During use, the fixed coal retaining plate 30 on the coal retaining plate 20 protects and blocks the coal transport. The T-shaped groove 11 on the base plate 10, in conjunction with the T-shaped slider, allows for horizontal adjustment of the coal retaining plate 20, ensuring it is in the appropriate position. This also facilitates the conveying and cleaning of coal slag. Specifically, pulling the U-shaped handle 45 compresses the positioning plate 42, storing and compressing the telescopic spring 41. Simultaneously, the positioning block 43 disengages from the groove 46. After the base block slides to the appropriate position in the T-shaped groove 11, releasing the U-shaped handle 45 allows the telescopic spring 41 to reset, thereby activating the rubber support under the positioning block 43. The pad 44 contacts the friction pad 47 in the groove 46 to limit and fix the coal retaining plate 20. The operation is simple. When the fixed coal retaining plate 30 is damaged or falls off in an emergency, the rotating baffle 26 on the rotating shaft 25 is operated to disengage the rotating baffle 26 from the arc-shaped rotating groove 27 of the spare coal retaining plate 24. The spare coal retaining plate 24 will descend through the action of the fixed slide 21, the fixed slider 22 and the L-shaped connecting rod 23, so that the spare coal retaining plate 24 temporarily completes the blocking and protection of coal, replacing the original fixed coal retaining plate 30 to work, avoiding affecting the normal transportation and production of the belt conveyor, and helping to improve the working efficiency of coal mine production operations.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
