Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coal processing and conveying technology, and in particular relates to a windbreak structure at the bottom of a coal chuting pipe. Background Technology
[0002] Coal chutes are a general term for coal conveying pipelines in industries such as coal, ports, and thermal power. They are key channels connecting upstream conveyor belts and downstream equipment. Their main function is to achieve efficient and stable conveying of coal particles. Some coal chutes are equipped with wind deflectors at the bottom. When there is coal, the weight and impact force of the coal cause the wind deflectors to open. When there is no coal, the wind deflectors hang down and close under their own weight, thus playing the role of blocking wind and preventing coal dust from flying.
[0003] After a period of use, the wind deflector may weaken due to prolonged contact and friction with coal and impact, necessitating replacement and repositioning. To ensure the reliability of the wind deflector's fixation, a bottom wind deflector structure for the coal chute is required. This structure uses a bidirectional threaded rod to engage the internal threaded block with a locking block, allowing the wind deflector to be pre-fixed and then secured with bolts. This effectively reduces the need for repeated alignment of bolt holes during installation and provides a better fixing effect. Summary of the Invention
[0004] The purpose of this utility model is to provide a windbreak structure at the bottom of a coal chute, which uses a bidirectional threaded rod to drive the internal threaded block and the locking block to engage, so that the windbreak plate can be pre-fixed and fixed with bolts. This effectively reduces the need to repeatedly align the bolt holes when installing the windbreak plate and achieves a better fixing effect, thereby solving the aforementioned technical problems.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A bottom windbreak structure of a coal chute includes a fixed rod disposed on the inner wall of the coal chute, a U-shaped plate rotatably connected to the surface of the fixed rod, a windbreak plate disposed on the inner wall of the U-shaped plate, connecting plates fixedly connected to the left and right sides of the U-shaped plate, a connecting head fixedly connected to the bottom of the connecting plate by bolts, two internally threaded blocks slidably connected to the inner wall of the connecting head, a bidirectional threaded rod threadedly connected to the inner wall of the two internally threaded blocks, a fixed block fixedly connected to the inner wall of the connecting head by bolts, a slider integrally formed at the bottom of each of the two internally threaded blocks, an L-shaped rod fixedly connected to the left and right sides of the windbreak plate, a locking block fixedly connected to the top of the L-shaped rod by bolts, and a locking groove adapted to the locking block being opened on the surface of the internally threaded block.
[0006] Preferably, a limiting block is fixedly connected to the end of the bidirectional threaded rod, and the limiting block is an annular limiting block.
[0007] Preferably, the inner wall of the fixing block is adapted to the surface of the bidirectional threaded rod, and the inner wall of the fixing block is rotatably connected to the surface of the bidirectional threaded rod.
[0008] Preferably, the surface of the slider is adapted to the inner wall of the connector, and the surface of the slider and the inner wall of the connector are slidably connected.
[0009] Preferably, the surface of the locking block engages with the inner wall of the connector.
[0010] The beneficial effects of this utility model are: 1. This utility model uses a rotating bidirectional threaded rod to engage the internal threaded block with the locking block, thereby fixing the U-shaped plate and the windbreak plate. Then, the U-shaped plate and the windbreak plate are fixed with bolts. This effectively reduces the need to repeatedly align the bolt holes when installing the windbreak plate and achieves a better fixing effect. 2. This utility model limits the movement of the internal thread block by setting a limiting block, effectively preventing the internal thread block from accidentally slipping off the surface of the bidirectional threaded rod during movement.

[0013] In the following description, embodiments of the bottom windbreak structure of the coal chute of this invention will be described with reference to the accompanying drawings. Example 1:
[0014] Figure 1-5 This invention illustrates a bottom windbreak structure for a coal chute 1 according to an embodiment of the present invention. The structure includes: a fixed rod 2 disposed on the inner wall of the coal chute 1; a U-shaped plate 3 rotatably connected to the surface of the fixed rod 2; a windbreak plate 4 disposed on the inner wall of the U-shaped plate 3; connecting plates 5 fixedly connected to both the left and right sides of the U-shaped plate 3; a connecting head 6 fixedly connected to the bottom of the connecting plate 5 by bolts; two internally threaded blocks 7 slidably connected to the inner wall of the connecting head 6; a bidirectional threaded rod 8 threadedly connected to the inner walls of the two internally threaded blocks 7; and a limiting block 9 fixedly connected to the end of the bidirectional threaded rod 8. The limiting block 9 is an annular limiting block. The movement of the internal threaded block 7 is limited by the setting of the limit block 9, which effectively prevents the internal threaded block 7 from accidentally slipping off the surface of the bidirectional threaded rod 8 during movement. The inner wall of the connector 6 is fixedly connected to the fixing block 10 by bolts. The bottom of the two internal threaded blocks 7 is integrally formed with a slider 11. The left and right sides of the wind baffle 4 are fixedly connected to the L-shaped rod 12. The top of the L-shaped rod 12 is fixedly connected to the locking block 13 by bolts. The surface of the locking block 13 engages with the inner wall of the connector 6. The surface of the internal threaded block 7 is provided with a locking groove 14 that matches the locking block 13. Example 2:
[0015] Figure 1-5 This invention illustrates a bottom windbreak structure for a coal chute according to an embodiment of the present invention. The structure includes: a fixed rod 2 disposed on the inner wall of the coal chute 1; a U-shaped plate 3 rotatably connected to the surface of the fixed rod 2; a windbreak plate 4 disposed on the inner wall of the U-shaped plate 3; connecting plates 5 fixedly connected to both the left and right sides of the U-shaped plate 3; a connecting head 6 fixedly connected to the bottom of the connecting plate 5 by bolts; two internally threaded blocks 7 slidably connected to the inner wall of the connecting head 6; a bidirectional threaded rod 8 threadedly connected to the inner walls of the two internally threaded blocks 7; and a fixed block 10 fixedly connected to the inner wall of the connecting head 6 by bolts. The inner wall of the fixing block 10 is adapted to the surface of the bidirectional threaded rod 8, and the inner wall of the fixing block 10 is rotatably connected to the surface of the bidirectional threaded rod 8. The bottom of the two internal threaded blocks 7 is integrally formed with a slider 11. The surface of the slider 11 is adapted to the inner wall of the connector 6, and the surface of the slider 11 is slidably connected to the inner wall of the connector 6. The left and right sides of the baffle plate 4 are fixedly connected with L-shaped rods 12. The top of the L-shaped rod 12 is fixedly connected with a locking block 13 by bolts. The surface of the internal threaded block 7 is provided with a locking groove 14 adapted to the locking block 13.
[0016] Working principle: When using this utility model, the user rotates the bidirectional threaded rod 8. Under the limiting action of the fixed block 10, the bidirectional threaded rod 8 rotates on the inner wall of the fixed block 10, thereby causing the bidirectional threaded rod 8 to drive the two internal threaded blocks 7 to move relative to each other. During this process, the movement of the internal threaded blocks 7 is limited by the slider 11, which causes the internal threaded blocks 7 to disengage the slot 14 and the block 13. Subsequently, the connecting plate 5 and the L-shaped rod 12 respectively drive the U-shaped plate 3 and the windproof plate 4 to release the pre-fixed connection. The U-shaped plate 3 and the wind deflector 4 are released by rotating the bolts. After the wind deflector 4 is replaced, the two-way threaded rod 8 is rotated, causing the two-way threaded rod 8 to move relative to each other on the inner wall of the connector 6. This causes the internal threaded blocks 7 to engage with the slot 14 and the block 13, thus pre-fixing the U-shaped plate 3 and the wind deflector 4. The U-shaped plate 3 and the wind deflector 4 are then fixed with bolts. This effectively reduces the need to repeatedly align the bolt holes when installing the wind deflector and provides a better fixing effect.
[0017] In summary, the bottom windbreak structure of this coal chute, by rotating the bidirectional threaded rod 8, causes the internal threaded block 7 to engage with the locking block 13, thereby fixing the U-shaped plate 3 and the windbreak plate 4. Subsequently, the U-shaped plate 3 and the windbreak plate 4 are fixed together with bolts, which effectively reduces the need to repeatedly align the bolt holes when installing the windbreak plate and achieves a better fixing effect.
