Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a leak-proof device for belt conveyors. Background Technology

[0002] Leakage prevention devices are used to prevent materials from scattering during the conveying process. They are usually composed of components such as baffles, sealing skirts, and cleaners. They can reduce material loss and environmental pollution. During the operation of belt conveyors, problems such as edge leakage and interface spillage can easily occur due to belt deviation, uneven material particle size, or excessive drop, which affects the conveying efficiency.

[0003] In the existing technology, some belt conveyor anti-leakage devices achieve leakage prevention by combining multi-layer sealing and precise guidance. Multiple protective structures are set at the key gap between the conveyor belt and the frame: First, elastic skirt baffles are installed on both sides of the conveyor belt, which use the deformation characteristics of flexible materials such as rubber to stick tightly to the surface of the conveyor belt and prevent side leakage caused by bumps and tilting during the conveying process.

[0004] However, in actual use, leakage will cause the conveyed material to scatter during the conveying process. Especially for high-value materials, the accumulated loss will directly increase the raw material procurement cost. In order to address the above problems, a leakage prevention device for belt conveyors is proposed. Utility Model Content

A mounting housing is fixedly connected to the outside of the second fixing plate. A limit plate is slidably connected inside the mounting housing. A sliding rod is fixedly connected to the outside of the limit plate. A baffle is fixedly connected to the other end of the sliding rod. A reset spring is sleeved on the outside of the sliding rod.

[0013] As a further description of the above technical solution:

[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] Reference Figures 1 to 3 This utility model provides an embodiment of a leak-proof device for a belt conveyor, comprising an installation frame 1. The installation frame 1 provides a solid installation foundation for the entire leak-proof device, bears the weight of each component, and evenly transmits the force to the conveyor frame, ensuring the device remains stable during the operation of the conveyor. Top plates 2 are fixedly connected to the front and rear sides of the top of the installation frame 1. The two top plates 2 are arranged in parallel and are located on the front and rear sides of the conveyor belt 3, forming a protective barrier to prevent material from leaking from the edge of the conveyor belt 3 to both sides. At the same time, they provide an installation platform for the extension frame 4 and the cleaning and disassembly mechanism. The conveyor belt 3 is arranged on the adjacent side of the two top plates 2. The conveyor belt 3 is the core conveying component of the belt conveyor. Its surface maintains a certain gap with the inner side of the top plate 2. It circulates under the drive of the motor 5 to convey materials. The extension frame 4 is fixedly connected inside the top plate 2. The main function of the extension frame 4 is to install the leak-proof mechanism, extending the leak-proof component to the top or side of the conveyor belt 3 to enhance the leak-proof effect. The leak-proof mechanism is fixedly connected to the top of the extension frame 4.

[0036] Cleaning disassembly and assembly mechanisms are fixedly connected to the front and rear ends of the outer right side of the top plate 2. These mechanisms include a fixed rod 20, which provides guiding support for the sliding block 22, ensuring its smooth movement along a fixed direction. The fixed rod 20 also bears the elastic force of the mounting spring 21 and the reaction force of the brush 23 during operation. The fixed rod 20 is externally fixed to the front and rear sides of the top plate 2. A mounting spring 21 is sleeved on the outside of the fixed rod 20. In its natural state, the mounting spring 21 is extended, applying a pushing force to the sliding block 22, causing it to drive the brush 23 to tightly adhere to the surface of the conveyor belt 3, ensuring a cleaning effect. When large pieces of material pass through the conveyor belt 3, the mounting spring 21 can be compressed to buffer and prevent damage to the brush 23, thus providing protection. A sliding block 22 is slidably connected to the outside of the fixed rod 20. The sliding block 22 serves as… The supporting component is used to install the brush 23 and drive the brush 23 to keep in contact with the conveyor belt 3 under the action of the spring 21. At the same time, it is convenient to adjust the position of the brush 23. The top of the sliding block 22 is fixedly connected to the brush 23. When the conveyor belt 3 is running, the brush 23 can clean the material remaining on the surface of the conveyor belt 3, prevent the material from accumulating at the edge of the conveyor belt 3 and leaking, and keep the conveyor belt 3 clean and reduce equipment wear. The bottom of the sliding block 22 is fixedly connected to the connecting shaft 24. The connecting shaft 24 provides a rotation fulcrum for the rotating plate 25, so that the rotating plate 25 can rotate flexibly around the connecting shaft 24 to realize the clamping or separation of the positioning rod 27 and the limiting rod 28. The rotating plate 25 is rotatably connected to the outside of the connecting shaft 24. The rotating plate 25 is a lever structure made of bent metal plate and is sleeved on the outside of the connecting shaft 24 through bearings.

[0037] The rotating plate 25 can drive the positioning rod 27 to move by rotating. Multiple tension springs 26 are fixedly connected to the outside of the rotating plate 25. These tension springs 26 are always in a stretched state, applying tension to the rotating plate 25, causing the rotating plate 25 to drive the positioning rod 27 to remain locked with the limiting rod 28. This ensures that the sliding block 22 will not move unexpectedly during operation. The positioning rod 27, through its locking engagement with the limiting rod 28, keeps the rotating plate... The position of 25 is fixed, thereby restricting the sliding of the sliding block 22, so that the brush 23 maintains a stable position in the non-maintenance state. The external sliding connection of the sliding block 22 is a limit rod 28, which provides multiple clamping positions for the positioning rod 27. By adjusting the cooperation between the positioning rod 27 and different slots, the position of the sliding block 22 can be adjusted, thereby adjusting the contact pressure between the brush 23 and the conveyor belt 3 to adapt to the cleaning needs of different materials. The external of the limit rod 28 is clamped to the internal of the positioning rod 27.

[0038] The anti-leakage mechanism includes a motor 5, which serves as the power source for the mechanism and provides stable rotational power. By precisely controlling the speed and direction, the motor 5 drives the active rod 6 to rotate, providing power support for the movement of the entire mechanism. The motor 5 is externally fixedly connected to the top of the extension frame 4. The drive end of the motor 5 is fixedly connected to the active rod 6, which transmits the rotational motion of the motor 5 to the rotating plates 8 on both sides and the pulley group 10. It is the core shaft component for power transmission. The active rod 6 is externally rotatably connected to a fixed plate 7, which provides stable support and a rotation fulcrum for the active rod 6, ensuring that the active rod 6 maintains coaxiality during rotation and reducing the impact of vibration on the operation of the mechanism. The fixed plate 7 is rotatably connected to the front and rear sides of the fixed plate 7. The rotating plates 8 reciprocate under the drive of the active rod 6, converting the rotational motion of the active rod 6 into the linear reciprocating motion of the sliding plate 9, realizing the transmission of force and the conversion of motion form. The other end of the rotating plate 8 is rotatably connected to the sliding plate 9, which reciprocates horizontally under the drive of the rotating plate 8.

[0039] The extension frame 13 and the connected baffle 19 move synchronously, achieving dynamic contact between the baffle 19 and the conveyor belt 3. The top of the sliding plate 9 is fixedly connected to the extension frame 13. The function of the extension frame 13 is to connect the sliding plate 9 and the reset assembly, transmit the movement of the sliding plate 9 to the baffle 19, and provide a mounting base for the reset assembly. The external of the extension frame 13 is fixedly connected to the reset assembly, which includes a fixing plate 14. The fixing plate 14 provides a stable mounting point for the mounting housing 15. The external of the fixing plate 14 is fixedly connected to the outside of the extension frame 13. A mounting housing 15 is fixedly connected to the sliding rod 17. The mounting housing 15 provides space for the limiting plate 16 and the return spring 18, and guides the sliding of the sliding rod 17 to ensure that the sliding rod 17 moves smoothly along the axial direction. The limiting plate 16 is slidably connected inside the mounting housing 15, and the sliding rod 17 is fixedly connected to the outside of the limiting plate 16. Under the guidance of the mounting housing 15, the sliding rod 17 drives the baffle 19 to perform telescopic movement, so that the baffle 19 can adaptively adjust according to the position change of the conveyor belt 3. The other end of the sliding rod 17 is fixedly connected to the baffle 19, which is the direct component for preventing material leakage.

[0040] Under the elastic force of the return spring 18, it closely adheres to the side of the conveyor belt 3, forming a sealing barrier to prevent material leakage from the edge of the conveyor belt 3. The return spring 18 is sleeved on the outside of the sliding rod 17. The pulley group 10 is fixedly connected to the outside of the driving rod 6. The function of the pulley group 10 is to transmit the rotational motion of the driving rod 6 to the driven rod 11, so as to realize the synchronous rotation of the driving rod 6 and the driven rod 11, and ensure that the movements of the rotating plates 8 on both sides are coordinated. The driven rod 11 is fixedly connected to the bottom of the pulley group 10. The driven rod 11 rotates synchronously with the driving rod 6 under the drive of the pulley group 10, ensuring that the sliding plates 9 and the baffles 19 on the front and rear sides move in the same way, and avoiding the leakage problem caused by the asynchronous movement of the two sides. The driven rod 11 is fixedly connected to the top of the extension frame 4.

[0041] Reference Figures 3 to 6 A waste collection box 29 is fixedly connected to the outer right side of the top plate 2. When the brush 23 cleans the residual material on the surface of the conveyor belt 3, the swept-off waste will fall into the waste collection box 29 under the action of gravity, realizing the centralized collection of waste and avoiding the material from scattering under the conveyor, causing environmental pollution and resource waste. At the same time, it reduces the workload of manual cleaning. The outer side of the brush 23 is in contact with the outer side of the conveyor belt 3. One end of the tension spring 26 is fixedly connected to the outer side of the rotating plate 25, and the other end of the tension spring 26 is fixedly connected to the outer side of the sliding block 22. The fixed tension spring 26 is always in a stretched state, generating a stable pulling force on the rotating plate 25, so that the rotating plate 25 drives the positioning rod 27 to be tightly locked into the groove of the limiting rod 28, thereby firmly locking the position of the sliding block 22. This fixed connection method prevents the tension spring 26 from falling off or shifting during long-term use, ensuring the reliability of the locking structure. The top of the extension frame 4 is fixedly connected with multiple limit blocks 12, and the outer bottom end of the sliding plate 9 is slidably connected to the outside of the limit blocks 12.

[0042] Working principle: By starting the motor 5, the motor 5 drives the drive rod 6 to rotate. The rotation of the drive rod 6 drives the driven rod 11 to rotate through the pulley group 10. The driven rod 11 and the drive rod 6 drive the rotating plate 8 to rotate. The rotating plate 8 drives the sliding plate 9 to slide. The sliding plate 9 then drives the baffle 19 to slide at the top of the conveyor belt 3 through the fixed plate 14. When the material passes through, the material squeezes the baffle 19, which in turn squeezes the sliding rod 17. The sliding rod 17 slides inside the mounting housing 15, which causes the return spring 18 to deform, thus preventing material leakage.

[0043] When the conveyor belt 3 is started, the brush 23 cleans the surface of the conveyor belt 3 during its rotation. Because of the installed spring 21, even after wear, the brush 23 can still clean the surface of the conveyor belt 3 through the reaction force of the spring 21. When assembling or disassembling the brush 23, pulling the limit lever 28 allows the positioning lever 27 to slide inside the sliding block 22. At this time, pressing the rotating plate 25 causes the rotating plate 25 to engage with the tension spring. The spring 26 is compressed, which allows the rotating plate 25 to drive the positioning rod 27 to separate from the brush 23, and then the brush 23 can be taken out. When installing the brush 23, the brush 23 is placed inside the sliding block 22, and then the rotating plate 25 is released, causing the tension spring 26 to rebound, which allows the rotating plate 25 to drive the positioning rod 27 to lock with the brush 23. At this time, the limit rod 28 is inserted, which locks with the positioning rod 27.
