Description

Technical Field

[0001] This utility model relates to the field of coal conveying technology, and more specifically, to a conveying mechanism for a coal conveying system. Background Technology

[0002] A coal conveying system refers to a comprehensive facility used for the transportation, storage, and processing of coal throughout its journey from the mining site to its final destination. Coal conveyors are crucial equipment in mining areas, power plants, and other industrial settings, primarily transporting coal from one location to another.

[0003] Belt conveyors are one of the most common coal conveying devices. Driven by a motor, the conveyor belt moves, moving the material placed on it. During operation, coal chunks or ash often adhere to the conveyor belt, increasing its load and affecting its normal conveying efficiency. Furthermore, these materials can spill during belt reversals, causing pollution and waste.

[0004] Current methods typically involve manual cleaning during shutdown, which is labor-intensive and time-consuming, impacting coal conveying efficiency. Another approach involves installing scrapers at the bottom of the conveyor belt to remove adhering coal during belt folding. However, when encountering highly adhesive coal, the scrapers become stuck, causing belt jamming. This can damage the conveyor belt and malfunction the drive system, preventing continued coal transport. The high failure and damage rates, coupled with the inability to adjust scraper height according to specific requirements, result in poor performance.

[0005] Therefore, it is necessary to provide a conveying mechanism for a coal conveying system to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide a conveying mechanism for a coal conveying system to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A conveying mechanism for a coal conveying system includes a conveyor with a conveyor belt mounted thereon, and further includes:

[0009] A support base is provided on the conveyor, a support plate is provided on the support base, a rotating shaft is rotatably provided on the support plate, and a connecting seat is provided on the rotating shaft;

[0010] A torsion spring, one end of which is connected to the support plate and the other end of which is connected to the rotating shaft;

[0011] A scraper is detachably mounted on the connecting seat, and the scraper is located below the conveyor belt;

[0012] An adjusting component, connected to the support base, is used to adjust the height of the scraper.

[0013] Furthermore, the adjustment component includes:

[0014] A base is disposed on the conveyor, and the interior of the base has an inner cavity that is slidably connected to the support seat;

[0015] A screw is threaded to the bottom of the base, and the upper end of the screw is rotatably connected to the support.

[0016] Furthermore, the bottom wall of the inner cavity is provided with a sleeve column, and a movable column connected to the support seat is movably inserted inside the sleeve column.

[0017] Furthermore, the support base has a sliding cavity inside, and an installation seat is slidably connected to the inner wall of the sliding cavity. The scraper is detachably connected to the installation seat, and a first elastic element is provided between the bottom wall of the sliding cavity and the installation seat.

[0018] Furthermore, the upper end of the mounting base is provided with a mounting groove, the scraper is provided with an insert plate that is adapted to the mounting groove, and the mounting base is provided with a limiting component for fixing the insert plate.

[0019] Furthermore, the insert plate has an insertion port, and the limiting component includes:

[0020] An inner groove is formed in the mounting base, and a limiting block is slidably provided on the inner wall of the inner groove. A second elastic element is provided between the limiting block and the inner wall of the inner groove.

[0021] The pull rod has one end connected to the limiting block and the other end movably passing through the outer wall of the mounting base.

[0022] Furthermore, the conveyor is equipped with a support frame, the base is mounted on the support frame, and a collection box is placed below the base.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This solution uses a scraper to remove coal lumps or ash adhering to the conveyor belt. When there are highly adhesive and hard coal lumps on the conveyor belt, if the scraper cannot remove them, the coal will cause the scraper to rotate. The scraper will drive the connecting seat and the rotating shaft to rotate, causing the torsion spring to elastically deform. The coal will then move past the scraper as the conveyor belt moves. The torsion spring will then drive the rotating shaft, connecting seat, and scraper back to their initial state. This avoids the situation where the currently fixed scraper blocks the highly adhesive and hard coal, causing the conveyor belt to jam. This greatly reduces the possibility of conveyor belt deformation and damage or drive equipment failure. Afterwards, the highly adhesive and hard coal can be manually removed by stopping the machine, further reducing the failure and damage rates, and demonstrating high practicality.

[0025] The height of the scraper can be changed by adjusting the components to move the support and connecting seat up or down, thereby adjusting the distance between the scraper and the conveyor belt. The height of the scraper can be adjusted according to the scraping requirements and specific conditions, making it highly flexible and suitable for various situations. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] Please see Figure 1-6 A conveying mechanism for a coal conveying system includes a conveyor 1 on which a conveyor belt 2 is mounted, and further includes:

[0036] Support base 3 is set on conveyor 1. Support plate 4 is set on support base 3. Rotating shaft 5 is rotatably set on support plate 4. Connecting seat 6 is set on rotating shaft 5.

[0037] The torsion spring 7 is connected at one end to the support plate 4 and at the other end to the rotating shaft 5;

[0038] The scraper 8 is detachably mounted on the connecting seat 6 and is located below the conveyor belt 2;

[0039] Adjustment component 9, connected to support base 3, is used to adjust the height of scraper 8.

[0040] During operation, conveyor 1 transports coal via conveyor belt 2. After conveyor belt 2 delivers the coal to the end discharge point, some coal chunks or coal ash will turn back with conveyor belt 2. When conveyor belt 2 carrying adhering coal moves from top to bottom and turns back, it will pass by conveyor belt 2. The scraper 8 can scrape off the coal chunks or coal ash adhering to conveyor belt 2, which can prevent the load on conveyor belt 2 from becoming too heavy, ensure the normal transport of conveyor belt 2, reduce coal spillage, and eliminate the need for manual cleaning by staff, saving time and labor and improving coal transport efficiency.

[0041] When there are highly adhesive and hard coal lumps on the conveyor belt 2, if the scraper 8 cannot scrape off the coal when it encounters the scraper 8, the coal will continue to move with the conveyor belt 2 and cause the scraper 8 to rotate. The scraper 8 will drive the connecting seat 6 and the rotating shaft 5 to rotate, and the torsion spring 7 will be subjected to the torsional torque of the rotating shaft 5, causing the torsion spring 7 to undergo elastic deformation. At this time, the coal will move with the conveyor belt 2 and pass over the scraper 8. After the coal is removed, the scraper 8 is no longer under force, the torsional torque on the torsion spring 7 is removed, and it will return to its initial state. The torsion spring 7 will then drive the rotating shaft 5, the connecting seat 6, and the scraper 8 to return to their initial state. That is, at this time, the scraper 8 continues to scrape the conveyor belt 2. This avoids the current fixed scraper 8 blocking the highly adhesive and hard coal, which would cause the conveyor belt 2 to jam. It greatly reduces the possibility of deformation and damage to the conveyor belt 2 or failure of the drive equipment, and can continue to transport coal. The highly adhesive and hard coal can be manually handled after the machine is stopped, reducing the failure rate and damage rate. It has high practicality and can be widely promoted and used.

[0042] The height of the scraper 8 can be changed by adjusting the component 9 to move the support base 3 and the connecting base 6 up or down, thereby adjusting the distance between the scraper 8 and the conveyor belt 2. The height of the scraper 8 can be adjusted according to the scraping requirements and specific conditions, which is highly flexible, applicable to various situations, and has good performance.

[0043] For preferred options, please refer to [link / reference]. Figure 2-3 and Figure 5 Adjustment component 9 includes:

[0044] The base 91 is mounted on the conveyor 1, and the interior of the base 91 has an inner cavity 92 that is slidably connected to the support base 3;

[0045] The screw 93 is threaded to the bottom of the base 91, and the upper end of the screw 93 is rotatably connected to the support 3.

[0046] Specifically, by rotating the screw 93, the support 3 can be moved up or down along the inner cavity 92 of the base 91, thereby adjusting the height of the support 3, which in turn adjusts the angle of the connecting seat 6 and the scraper 8.

[0047] Please see Figure 5 The bottom wall of the inner cavity 92 is provided with a sleeve post 10, and a movable column 11 connected to the support base 3 is movably inserted inside the sleeve post 10. With this design, when the support base 3 moves up or down along the inner cavity 92 of the base 91, the support base 3 will drive the movable column 11 to move up or down along the sleeve post 10. The cooperation between the movable column 11 and the sleeve post 10 not only improves the movement stability of the support base 3, but also further restricts the rotation of the support base 3.

[0048] For preferred options, please refer to [link / reference]. Figure 5-6 The support base 3 has a sliding cavity 12 inside, and the inner wall of the sliding cavity 12 is slidably connected to the mounting base 13. The scraper 8 is detachably connected to the mounting base 13. A first elastic element 14 is provided between the bottom wall of the sliding cavity 12 and the mounting base 13. The first elastic element 14 in this application can be a spring.

[0049] This design allows the scraper 8 to be in close contact with the surface of the conveyor belt 2. When the scraper 8 is squeezed, it will drive the mounting base 13 to move into the sliding cavity 12 and compress the first elastic element 14. The first elastic element 14 will also give the mounting base 13 and the scraper 8 a reaction force, so that the scraper 8 can always be in contact with the conveyor belt 2, improving the scraping effect of coal on the conveyor belt 2. Moreover, the scraper 8 and the surface of the conveyor belt 2 are in elastic contact, which can prevent the scraper 8 from damaging the surface of the conveyor belt 2.

[0050] For preferred options, please refer to [link / reference]. Figure 3-6 The mounting base 13 has a mounting groove 15 at its upper end. The scraper 8 has an insert plate 16 that matches the mounting groove 15. The mounting base 13 also has a limiting component 17 for fixing the insert plate 16. This design allows the scraper 8 to be detachably mounted on the mounting base 13. During installation, the insert plate 16 of the scraper 8 is inserted into the mounting groove 15 of the mounting base 13, and then the limiting component 17 fixes and limits the insert plate 16. During disassembly, the limiting component 17 is released to remove the insert plate 16 from the mounting groove 15, allowing the scraper 8 to be removed. This facilitates the inspection and replacement of the scraper 8, extending the service life of the device.

[0051] For preferred options, please refer to [link / reference]. Figure 3-6 The insertion plate 16 has an insertion port 18, and the limiting component 17 includes:

[0052] An inner groove 171 is formed in the mounting base 13. A limit block 172 is slidably provided on the inner wall of the inner groove 171. A second elastic element 173 is provided between the limit block 172 and the inner wall of the inner groove 171. The second elastic element 173 in this application can be a spring.

[0053] The pull rod 174 is connected at one end to the limit block 172, and at the other end it moves through the outer wall of the mounting base 13.

[0054] Specifically, before installing the scraper 8, the pull rod 174 can be pulled outward. The pull rod 174 will drive the limiting block 172 to move into the recessed groove 171 and compress the second elastic element 173. After the insert plate 16 of the scraper 8 is inserted into the mounting groove 15 of the mounting base 13, the pull rod 174 is released. The rebound force of the second elastic element 173 will reset and drive the limiting block 172 to move. The limiting block 172 will enter the insertion port 18 of the insert plate 16, thereby limiting and fixing the insert plate 16, thus completing the fixing of the scraper 8. The same principle applies when disassembling the scraper 8. Pulling the pull rod 174 outward will disengage the limiting block 172 from the insertion port 18, allowing the insert plate 16 to be moved out of the mounting groove 15, thus completing the disassembly of the scraper 8.

[0055] For preferred options, please refer to [link / reference]. Figure 1-2 The conveyor 1 is equipped with a support frame 19, and a base 91 is mounted on the support frame 19. A collection box 20 is placed below the base 91. This design uses the support frame 19 to support and install the base 91 and the components above it. Coal scraped off the conveyor belt 2 by the scraper 8 falls into the collection box 20 for collection, facilitating subsequent unified processing and reducing the difficulty of manual handling.
