Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt cleaning, in particular to a coal mine conveyor belt cleaner. Background Art

[0002] Coal mine conveyor belts require cleanliness. The quality of the raw coal hoisted during coal mining operations is unpredictable. When the raw coal is of poor quality, particularly when it is sticky due to moisture, some of the sticky coal can adhere to the conveyor belt's working surface and remain trapped during unloading. This can cause the sticky coal to enter the lower rollers in the return section, contaminating and sticking to them. This sticky coal entering the roller housing increases the radial and axial loads on the bearing seats, accelerating bearing wear. Sticky coal on the roller housing can also tear and roughen the belt's surface adhesive, accelerating belt wear and damage.

[0003] At present, coal mine conveyor belts can usually be cleaned in a variety of ways, such as by installing appropriate cleaning devices, such as primary cleaners, secondary cleaners, spray bars and cleaning boxes. However, there are many types and models of coal mine conveyor belts. When using the above-mentioned devices for cleaning, it is necessary to selectively adapt them according to the model and specifications of the conveyor belt. Therefore, the existing conveyor belt cleaning devices have the problem of poor adaptability. Therefore, a new type of cleaner is needed to solve this problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a coal mine conveyor belt cleaner, which can be adapted to conveyor belts of different models and specifications, so that the cleaner has a wide range of adaptability.

[0005] The technical solution to achieve the purpose of the utility model is: a coal mine conveyor belt cleaner, including a bracket, a slide is slidably connected to the bracket, a cleaning assembly is jointly provided on the bracket and the slide, and the cleaning assembly includes a first shell and a second shell, the two first shells are fixedly connected to the bracket, the two second shells are fixedly connected to the slide, two rotating rods are rotatably connected between the two first shells and the two second shells, two rotating plates are fixedly connected to the two rotating rods, and bristles are provided on both rotating plates.

[0006] Preferably, the cleaning assembly further comprises a worm gear and a worm, and a worm gear and a worm gear are disposed inside each of the first housing and the second housing, and the two worm gears are respectively engaged with the two worm gears.

[0007] Preferably, the two rotating rods pass through the first housing and the second housing respectively, and the two worm gears are fixedly connected to the two rotating rods respectively.

[0008] Preferably, the cleaning assembly further comprises a knob, wherein the two knobs are rotatably connected to a first housing and a second housing respectively, and the two knobs are respectively engaged with two worms.

[0009] Preferably, a fixing block is fixedly connected to the bracket, a screw is threadedly connected to the fixing block, and one end of the screw is rotatably connected to the slide.

[0010] Compared with the prior art, the present invention has the following significant advantages:

[0011] First, in the present invention, the cleaner can be moved to the end of the conveyor belt, that is, the unloading position of the coal blocks. By adjusting the positions of the two rotating plates, one of the rotating plates is pressed against the end of the conveyor belt, so that the coal blocks will be unloaded along the rotating plate during unloading, and the other rotating plate is pressed against the bottom of the conveyor belt. When the coal blocks are unloaded, the moist coal ash adhering to the surface of the conveyor belt will pass through this rotating plate. Brushes are provided on both rotating plates, and the bristles can be pressed tightly against the conveyor belt without affecting the normal operation of the conveyor belt. The bristles on the rotating plate used for unloading are used to press against the conveyor belt so that no gaps are generated during the unloading process, thereby preventing small pieces of coal blocks from leaking. The other rotating plate is pressed against the bottom of the conveyor belt, and the bristles on it are used to press against the surface of the conveyor belt to ensure that the bristles can sweep off the moist coal ash adhering to the surface of the conveyor belt.

[0012] Second: In the present invention, due to the different structures of conveyor belts of different models, some conveyor belts use inclined coal transportation, while some conveyor belts transport coal horizontally. Therefore, the position and angle of the two turn plates can be adjusted according to the specific shape of the conveyor belt, thereby ensuring that one turn plate is against the end of the conveyor belt to assist in the unloading of coal blocks, while the other turn plate and the bristles thereon are used to clean wet coal ash. When the two knobs are rotated, the worm in the first shell and the second shell will be driven to rotate, and then the worm gear and the rotating rod will be rotated. At this time, the two turn plates will rotate, thereby realizing angle adjustment. When the screw is rotated, the slide will be pushed to move in the bracket, thereby adjusting the relative position of the two turn plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a coal mine conveyor belt cleaner through improvement. The technical solution of the utility model is:

[0024] like Figures 1-6 As shown, a coal mine conveyor belt cleaner includes a bracket 1, a slide 2 is slidably connected to the bracket 1, and a cleaning component 3 is jointly provided on the bracket 1 and the slide 2. The cleaning component 3 includes a first shell 31 and a second shell 32. The two first shells 31 are fixedly connected to the bracket 1, and the two second shells 32 are fixedly connected to the slide 2. Two rotating rods 33 are rotatably connected between the two first shells 31 and the two second shells 32 respectively. Two rotating plates 34 are fixedly connected to the two rotating rods 33 respectively. Brushes 35 are provided on the two rotating plates 34. The rotating plates 34 are wider and the range of the bristles 35 is also wider, so that they can adapt to conveyor belts 6 of various widths.

[0025] Furthermore, the cleaning assembly 3 also includes a worm gear 36 and a worm 37. A worm gear 36 and a worm 37 are provided inside a first shell 31 and a second shell 32. The two worm gears 36 are respectively engaged with the two worm 37. The self-locking effect of the worm 36 and the worm gear 37 can prevent the rotating plate 34 from rotating due to force during use.

[0026] Furthermore, the two rotating rods 33 pass through the first housing 31 and the second housing 32 respectively, and the two worm gears 36 are fixedly connected to the two rotating rods 33 respectively.

[0027] Furthermore, the cleaning assembly 3 also includes knobs 38, which are respectively rotatably connected to a first shell 31 and a second shell 32, and the two knobs 38 are respectively engaged with two worm gears 37. The two knobs 38 can be manually rotated during the installation of the cleaner to adjust the cleaner to a state compatible with the corresponding conveyor belt 6.

[0028] Furthermore, a fixing block 4 is fixedly connected to the bracket 1 , a screw 5 is threadedly connected to the fixing block 4 , and one end of the screw 5 is rotatably connected to the slide 2 .

[0029] The specific working method is as follows: the cleaner is moved to the end of the conveyor belt 6, that is, the unloading position of the coal blocks, by adjusting the positions of the two rotating plates 34, so that one of the rotating plates 34 is against the end of the conveyor belt 6, so that the coal blocks will be unloaded along the rotating plate 34 during unloading, and the other rotating plate 34 is against the bottom of the conveyor belt 6. When the coal blocks are unloaded, the wet coal ash adhered to the surface of the conveyor belt 6 will pass through this rotating plate 34. Both rotating plates 34 are provided with brushes 35, and the brushes 35 can be tightly against the conveyor belt 6 without affecting the normal operation of the conveyor belt 6. The brushes 35 on the rotating plate 34 for unloading are used to press against the conveyor belt 6 so that no gaps are generated during the unloading process, thereby preventing small pieces of coal from leaking. The other rotating plate 34 is against the bottom of the conveyor belt 6, and the brushes 35 on it are used to press against the surface of the conveyor belt 6 to ensure that the brushes 35 can sweep off the wet coal ash adhered to the surface of the conveyor belt 6. When there is a lot of wet coal ash cleaned up on the brushes 35, it will fall onto the bracket 1 and the slide The coal blocks for normal unloading are outside the bracket 1 and the slide 2, so the coal blocks and the cleaned wet coal ash can be separated. Due to the different structures of the conveyor belt 6 of different models, some conveyor belts 6 use inclined coal transportation, and some conveyor belts 6 transport coal horizontally. Therefore, the position and angle of the two rotating plates 34 can be adjusted according to the specific shape of the conveyor belt 6, so as to ensure that one rotating plate 34 is against the end of the conveyor belt 6 to assist in unloading the coal blocks, while the other rotating plate 34 and the bristles 35 thereon are used to clean the wet coal ash. When adjusting the position and angle of the rotating plate 34, the knob 38 or the screw 5 can be rotated respectively. When the two knobs 38 are rotated, the worm 37 in the first shell 31 and the second shell 32 will be driven to rotate, and then the worm gear 36 and the rotating rod 33 will be rotated. At this time, the two rotating plates 34 will rotate, thereby realizing angle adjustment. When the screw 5 is rotated, the screw 5 itself moves and pushes the slide 2 to move in the bracket 1, thereby adjusting the relative position of the two rotating plates 34.
