Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyors, specifically to a belt tail cleaner. Background Technology

[0002] Belt conveyors offer advantages such as large conveying capacity, simple structure, convenient maintenance, and standardized components. They are widely used in mining, metallurgy, and coal industries to transport loose materials or packaged goods. Depending on the conveying process requirements, they can be used individually, in combination, or integrated with other conveying equipment to form horizontal or inclined conveying systems to meet the needs of different production line layouts. During conveyor operation, the material on the tail end of the belt must be cleaned to prevent it from falling into the machine and damaging the conveyor rollers.

[0003] Chinese Patent Publication No. CN209651275U discloses an automatic adjusting sweeper for belt cleaning. This solution achieves the effect of supporting the sweeping belt while ensuring that the sweeping belt can fit tightly against the belt. When the sweeping belt wears and gaps appear directly between it and the belt, the sweeping belt ensures that it fits tightly against the belt under its own weight, thereby effectively cleaning up fallen materials and ensuring the safe use of the machine.

[0004] The above solution uses gravity to make the sweeping belt adhere to the surface of the belt to achieve the sweeping function. However, due to the limited positive pressure generated by its own weight, the interfacial friction is insufficient and it is difficult to overcome the adhesion of the material. This mechanical defect causes the sweeping belt to be lifted by the adhered material during operation, resulting in an unsatisfactory sweeping effect and failure to achieve thorough cleaning.

[0005] Therefore, a belt end cleaner is proposed to address the above problems. Utility Model Content

[0006] This utility model proposes a belt end cleaner, which achieves continuous pressure on the cleaning belt through the coordinated action of the swing arm and the connecting part, forcing the cleaning belt to come into close contact with the conveyor belt. Compared with the solution that relies solely on its own weight, this design significantly increases the pressure on the contact surface between the cleaning belt and the conveyor belt through mechanical force amplification, thereby greatly enhancing the interface friction and material stripping ability, and thus improving the cleaning effect.

[0007] Therefore, the technical solution adopted is as follows:

[0008] A belt end cleaner includes a conveyor and a cleaning mechanism. The conveyor includes a frame and a conveyor belt. The cleaning mechanism is mounted on the conveyor and includes a pair of support frames mounted on the frame. A crossbeam is installed between the pair of support frames. A connecting frame is installed at the bottom of the crossbeam. A pair of connecting plates are installed at the bottom of the connecting frame. A cleaning belt is installed at the bottom of each pair of connecting plates. The cleaning belt is made of polyurethane material with a thickness of 10-20mm and abuts against the top of the conveyor belt. A pair of swing arms are rotatably connected to the bottom of the crossbeam. The end of the swing arm away from the crossbeam is rotatably connected to the connecting plate. A cross plate is installed between the pair of support frames. A connecting member for applying force to the swing arms is also provided on one side of the cross plate.

[0009] Furthermore, the connecting frame is rotatably connected to the bottom of the crossbeam, and a mounting bracket is installed on the top of a pair of connecting plates, the mounting bracket being rotatably connected to the inner side of the connecting frame.

[0010] Furthermore, the pair of connecting plates are arranged at an angle of 30-60°.

[0011] Furthermore, a pair of support rollers are rotatably connected to the inner side of the frame, and both of the support rollers abut against the bottom of the conveyor belt.

[0012] Furthermore, the connector includes a sleeve and a movable column, the movable column being installed into the inner cavity of the sleeve and slidably connected to the sleeve.

[0013] Furthermore, a second mounting block is installed at the end of the sleeve, and the second mounting block is rotatably connected to the cross plate; a first mounting block is installed at the end of the movable column, and the first mounting block is rotatably connected to the swing arm.

[0014] Furthermore, the connector also includes a spring, a sleeve block is installed on the outer wall of the sleeve, the spring is sleeved onto the outer wall of the sleeve, and the two ends of the spring are respectively connected to the first mounting block and the sleeve block.

[0015] The working principle and beneficial effects of this application are as follows:

[0016] By leveraging the combined action of the swing arm and connector, continuous pressure is applied to the sweeping belt, forcing it to come into close contact with the conveyor belt. Compared to solutions that rely solely on their own weight, this design significantly increases the pressure on the contact surface between the sweeping belt and the conveyor belt through mechanical force amplification, thereby greatly enhancing interfacial friction and material stripping ability, and ultimately improving the cleaning effect.

Detailed Implementation

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-5 As shown, a belt end cleaner includes a conveyor and a cleaning mechanism 3. The conveyor includes a frame 1 and a conveyor belt 2. The cleaning mechanism 3 is installed on the conveyor and includes a pair of support frames 31 installed on the frame 1. The support frames 31 are fixed to the side wall of the frame 1 by bolts. A crossbeam 32 is installed between the pair of support frames 31 and is fixed to the pair of support frames 31 by bolts. A connecting frame 33 is installed at the bottom of the crossbeam 32. A pair of connecting plates 34 are installed at the bottom of the connecting frame 33. A cleaning belt 35 is installed at the bottom of each pair of connecting plates 34. The cleaning belt 35 abuts against the top of the conveyor belt 2. A pair of swing arms 38 are rotatably connected to the bottom of the crossbeam 32. The end of the swing arm 38 away from the crossbeam 32 is rotatably connected to the connecting plate 34. A cross plate 36 is installed between the pair of support frames 31 and is fixed to the pair of support frames 31 by bolts. A connecting piece 37 for applying force to the swing arm 38 is also provided on one side of the cross plate 36.

[0026] In this embodiment, the front side of the conveyor belt 2 in the conveyor is used to convey materials. However, during the conveying process, some materials and impurities may fall onto the back side of the conveyor belt 2. If the materials and impurities are not cleaned in time, it is easy to cause the belt to slip. In this solution, during the operation of the conveyor, the cleaning mechanism 3 is used to clean the impurities on the back side of the conveyor belt 2 to prevent the falling materials from affecting the conveyor rollers in the conveyor.

[0027] Specifically, a cleaning belt 35 is provided at the bottom of the connecting plate 34, and the cleaning belt 35 can abut against the top of the conveyor belt 2. As the conveyor runs, the conveyor belt 2 moves, and the cleaning belt 35 is used to clean the material and impurities falling on the back of the conveyor belt 2. In addition, a swing arm 38 is provided, with its two ends rotatably connected to the crossbeam 32 and the connecting plate 34 respectively. The connecting piece 37 applies a downward force to the swing arm 38, forcing the connecting plate 34 to press downward, so that the cleaning belt 35 abuts tightly against the surface of the conveyor belt 2, thereby improving the overall cleaning effect.

[0028] like Figures 2-3 As shown, the connecting frame 33 is rotatably connected to the bottom of the crossbeam 32, and a mounting bracket 39 is installed on the top of a pair of connecting plates 34. The mounting bracket 39 is fixedly connected to the two connecting plates 34 at the bottom by welding, and the mounting bracket 39 is rotatably connected to the inner side of the connecting frame 33.

[0029] In this embodiment, the connecting frame 33 is rotatably connected to the bottom of the crossbeam 32, and the mounting frame 39 is also rotatably connected to the inner side of the crossbeam 32, thereby achieving the purpose of supporting the connecting plate 34, so that under the action of gravity, the bottom cleaning belt 35 of the pair of connecting plates 34 can abut against the opposite side of the conveyor belt 2.

[0030] like Figure 3 As shown, a pair of connecting plates 34 are set at an angle of 30-60°.

[0031] like Figure 2 As shown, a pair of support rollers 4 are rotatably connected to the inner side of the frame 1, and both of the support rollers 4 abut against the bottom of the conveyor belt 2.

[0032] In this embodiment, by providing a pair of support rollers 4 inside the frame 1, the conveyor belt 2 can be supported from below, so that the cleaning belt 35 is in close contact with the reverse side of the conveyor belt 2.

[0033] like Figures 3-5As shown, the connector 37 includes a sleeve 371 and a movable column 373. The movable column 373 is installed into the inner cavity of the sleeve 371 and is slidably connected to the sleeve 371. A second mounting block 376 is installed at the end of the sleeve 371 and is rotatably connected to the cross plate 36. A first mounting block 374 is installed at the end of the movable column 373 and is rotatably connected to the swing arm 38. The connector 37 also includes a spring 375. A sleeve block 372 is installed on the outer wall of the sleeve 371. The spring 375 is sleeved on the outer wall of the sleeve 371, and both ends of the spring 375 are connected to the first mounting block 374 and the sleeve block 372, respectively.

[0034] In this embodiment, a certain tension is generated by the spring 375, which causes the movable column 373 to move into the sleeve 371, thereby applying a force to the swing arm 38 and forcing a pair of connecting plates 34 to press downward, thereby making the sweeping belt 35 tightly abut against the conveyor belt 2. The tight abutment ensures that the sweeping belt 35 effectively removes debris from the reverse side of the conveyor belt 2, improving cleaning efficiency.

[0035] Specifically, spring 375 is a tension spring.

[0036] Working principle:

[0037] By providing a cleaning belt 35 at the bottom of the connecting plate 34, and the cleaning belt 35 being able to abut against the reverse side of the conveyor belt 2, the conveyor belt 2 moves as the conveyor runs, and the cleaning belt 35 is used to clean the material and impurities on the reverse side of the conveyor belt 2. In addition, by providing a swing arm 38, the two ends of which are rotatably connected to the crossbeam 32 and the connecting plate 34 respectively, and by providing a certain tension through the spring 375, the movable column 373 moves into the sleeve 371, thereby applying a force to the swing arm 38, forcing the pair of connecting plates 34 to press downward, thereby making the cleaning belt 35 tightly abut against the conveyor belt 2, improving the overall cleaning effect.

[0038] 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 shall be included within the protection scope of the present utility model.
