Description

Technical Field

[0001] This application relates to the field of coal mine conveying technology, and more specifically, to a belt cleaning mechanism and a coal mine conveyor belt. Background Technology

[0002] A coal mine conveyor belt is a coal conveying system, including at least one belt conveyor mechanism and corresponding cleaning mechanisms. Its main task is to transport coal, and secondly, to transport waste gangue to the surface and materials and equipment to the underground use location. The surface of the conveyor belt used in coal mine transportation will have residual waste residue, which needs to be cleaned by an automatic pressing belt cleaner. The existing automatic pressing belt cleaner is too cumbersome to assemble with the conveyor belt, requiring users to use a lot of tools and wasting a lot of energy, making it inconvenient to use.

[0003] In response, Chinese patent application number CN202220441631.7 discloses an automatic clamping belt cleaner for coal mine transportation. This solution mainly involves the coordinated use of an automatic clamping belt cleaner, a conveyor belt, a mating block, a T-block, a positioning groove, a housing, a T-groove, a positioning component, and a control component. The user uses the coordination between the control components to move the positioning rod out of the T-groove, then installs the automatic clamping belt cleaner on the front side of the conveyor belt, while simultaneously moving the T-block into the T-groove. Finally, the positioning component completes the positioning. This solution solves the problem that the existing automatic clamping belt cleaner is too cumbersome to assemble with the conveyor belt, making it inconvenient for users.

[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0005] When using the above solution, one person needs to keep pushing the control block to make the positioning rod leave the positioning groove of the T-shaped block, and then another person puts the matching block on the sweeper onto the T-shaped block before the control block can be released. Moreover, control blocks are set at both ends of the conveyor belt. Therefore, the above solution requires at least two people to operate, which is quite troublesome. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this application provides a belt cleaning mechanism and a coal mine conveyor belt, which can solve the problems mentioned in the background art.

[0007] Firstly, the technical solution adopted by the embodiments of this application to solve its technical problem is: a belt cleaning mechanism, including a conveying component and a cleaning component.

[0008] The conveying assembly includes a frame and a belt. A drive device is provided on the frame to drive the belt. The cleaning assembly includes a bracket, a scraper, and a pin. A rod is fixedly connected to both ends of the bracket. A pin sleeve adapted to the rod is fixedly connected to the frame. The pin is pin-connected to the corresponding rod and the pin sleeve.

[0009] In one specific implementation, the lower end of the pin sleeve is fixedly connected to a nut that is screwed onto the pin.

[0010] In one specific implementation, both the insert rod and the pin sleeve have chamfered corners at their radial openings.

[0011] In one specific implementation, a pull ring is provided at the upper end of the pin.

[0012] In one specific implementation, the scraper component includes a rotating frame, which is rotatably connected to the support, and an elastic element is further provided between the rotating frame and the support.

[0013] In one specific implementation, the scraper component further includes a scraper, which is inserted into the rotating frame and movably pressed against the surface of the belt. A pressure plate is hinged to both ends of the rotating frame, and pins are evenly distributed and fixed on the pressure plate.

[0014] In one specific implementation, one end of one of the pressure plates is hinged to an eccentric bolt, the other end of which is movable and fastened to one end of the other pressure plate.

[0015] Secondly, the present invention also provides a coal mine conveyor belt, including the above-mentioned belt cleaning mechanism.

[0016] The advantages of the embodiments of this application are:

[0017] 1. The cleaning component can be easily and quickly installed onto the conveying component using the insertion rod, and then the insertion rod can be locked with the pin. This can be operated by a single person.

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art above, and the overall idea is as follows:

[0025] Please see Figure 1 A belt cleaning mechanism includes a conveying assembly 100 and a cleaning assembly 200.

[0026] The cleaning component 200 can be easily and quickly installed onto the conveying component 100 using the insertion rod 240, which can be operated by a single person. The scraper 223 is clamped by tightening two pressure plates 224 with pins using eccentric bolts 225, which facilitates the disassembly and assembly of the scraper 223 and is beneficial for maintenance.

[0027] Please see Figure 1-4 The conveying assembly 100 includes a frame 110 and a belt 120. A drive unit is mounted on the frame 110 to drive the belt 120. The sweeping assembly 200 includes a bracket 210, a scraper 220, and a pin 230. Insert rods 240 are fixedly connected to both ends of the bracket 210. A pin sleeve 130, adapted to the insert rod 240, is fixedly connected to the frame 110. The pin 230 is pinned to the corresponding insert rod 240 and pin sleeve 130. During installation, the entire sweeping assembly 200 is lifted until the insert rod 240 is inserted into the pin sleeve 130 on the frame 110, then released. The pin 230 is then passed through the pin sleeve 130 and the insert rod 240 to lock the insert rod 240 in place, thus completing the installation of the sweeping assembly 200. This can be operated by a single person.

[0028] Please see Figure 2 The lower end of the sleeve 130 is fixedly connected to a nut 140, which is screwed onto the pin 230. Here, the pin 230 is screwed onto the nut 140 after it passes through the sleeve 130 and the rod 240. This can prevent the pin 230 from being accidentally pulled out during use, which could cause a malfunction.

[0029] Please see Figure 1-3Both the radial openings of the insertion rod 240 and the pin sleeve 130 are chamfered. Here, the radial opening is used to accommodate the pin 230. Before the pin 230 is inserted into the insertion rod 240, the automatic clamping scraper 220 will press against the belt 120, causing the insertion rod 240 to move backward. That is, the opening on the pin sleeve 130 is not coaxial with the opening on the insertion rod 240. Therefore, by setting the chamfer, the pin 230 is guided to pass into the insertion rod 240.

[0030] Please see Figure 1-2 A pull ring is provided at the upper end of the pin 230. Here, the pull ring is designed for easy gripping and rotation.

[0031] Please see Figure 1-3 The scraper component 220 includes a rotating frame 221, which is rotatably connected to the support 210. An elastic element 222 is also provided between the rotating frame 221 and the support 210. Here, the elastic element 222 maintains the tendency of the rotating frame 221 to deflect relative to the belt 120, thereby achieving an automatic clamping effect. In this embodiment, the elastic element 222 uses a spring to push the rotating frame 221 to deflect. The spring is sleeved on a guide rod, which has a through hole in the radial direction. Before installing the cleaning component 200, tools such as screwdrivers can be inserted into this through hole in advance to limit the spring elasticity and prevent the scraper component 220 from pushing out the insertion rod 240. After inserting the pin 230, the screwdriver can be removed.

[0032] Please see Figure 1-4 The scraper component 220 also includes a scraper 223, which is inserted into the rotating frame 221. The scraper 223 is movably pressed against the surface of the belt 120. A pressure plate 224 is hinged to both ends of the rotating frame 221, and pins are evenly distributed and fixed on the pressure plate 224. Here, the rotating frame 221 is provided with a protrusion, and the scraper 223 is provided with a corresponding groove. The scraper 223 is inserted into the protrusion on the rotating frame 221, and then the pressure plates 224 on both sides are tightened together. All the pins on the pressure plate 224 are embedded in the scraper 223, forming a stable clamping effect on the scraper 223, achieving rapid installation.

[0033] Please see Figure 2-4 One end of one of the pressure plates 224 is hinged to an eccentric bolt 225, and the other end of the eccentric bolt 225 is movable and tightened at one end of the other pressure plate 224. Here, when the two pressure plates 224 are joined together, the eccentric bolt 225 is deflected and pressed onto the opposite pressure plate 224, and then deflected and tightened. No tools are required, making it easy to operate.

[0034] Please see Figure 1-4 The present invention also provides a coal mine conveyor belt, including the above-mentioned belt cleaning mechanism.

[0035] When using this application: Insert a screwdriver or other tool into the through hole to restrict the spring's elasticity. Then lift the entire cleaning assembly 200 so that the insert rod 240 is inserted into the pin sleeve 130 on the frame 110, and then release. Next, the pin 230 passes through the pin sleeve 130 and the insert rod 240 to lock the insert rod 240. Finally, pull out the screwdriver or other tool to complete the installation of the cleaning assembly 200. This can be operated by a single person. When replacing the scraper 223, first use a screwdriver or other tool to restrict the spring's elasticity, loosen and deflect the eccentric bolt 225, open the two pressure plates 224, and then remove the scraper 223 for replacement. After inserting the new scraper 223 into the rotating frame 221, tighten the two pressure plates 224 again and pull out the screwdriver.

[0036] In summary, this application utilizes the insertion rod 240 to conveniently and quickly install the cleaning component 200 onto the conveying component 100, which can be operated by a single person. The scraper 223 is clamped by tightening the two pressure plates 224 with pins using the eccentric bolts 225, which facilitates the disassembly and assembly of the scraper 223 and is beneficial for maintenance.

[0037] It should be noted that the specific models and specifications of belt 120, nut 140 and eccentric bolt 225 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
