Description

Technical Field

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

[0002] The belt conveyor in the coal preparation workshop is mainly responsible for transporting coal and coke. Since the coal preparation and coke transport system transports a large amount of coke, a large amount of coke powder is attached to the belt, which causes serious wear of the belt and rollers. In order to reduce the frequent replacement of belts due to wear, a cleaner is usually installed at the head wheel of the belt to clean the coke powder on the belt surface.

[0003] The existing belt head wheel cleaner adopts an integrated scraper, and its cleaning principle is to attach the scraper to one side of the belt, and as the belt moves, the coke powder attached to the surface of the belt is scraped and cleaned.

[0004] However, since the scraper is an integrated structure, when the scraper is partially worn, it needs to be replaced as a whole, which increases maintenance costs and time costs. In addition, due to the uneven flatness of the belt surface, this will cause the various contact points between the belt and the scraper to have position differences, and then the scraper part of the position cannot be completely attached to the belt, which reduces the cleaning effect and makes the scraper unable to effectively remove the coke powder on the belt surface. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a belt head pulley cleaner. The technical solution of the utility model is as follows:

[0006] The cam is secured to the chassis and has a plurality of locking plates, which are secured to the chassis by a spring, and the locking plates are secured to the chassis with a spring.

[0026] The utility model realizes cleaning of the coke powder on the belt surface by providing multiple groups of scrapers 6 attached to the belt. When the scraper 6 is worn, the angle of the hook-type mounting seat 4 and the scraper 6 can be changed by rotating the adjustment rod 7 until the scraper 6 and the belt are no longer attached. At this time, the worn scraper 6 can be removed from the corresponding hook-type mounting seat 4 and replaced without replacing the scraper 6 as a whole. In addition, the multiple groups of scrapers 6 can ensure that the scraper 6 is always attached to the belt through the elastic tension of the stretch spring 5, so that the cleaning efficiency is higher.

[0027] It should be noted that the head wheel is installed on the inner side of the belt, and the head wheel fixing frame is installed on both sides of the head wheel for supporting the head wheel.

[0028] Furthermore, a slide groove 21 is provided inside the fixing seat 2, a slider 31 is fixedly connected to the lower surface of the base plate 3, and the slider 31 is slidably connected to the inside of the slide groove 21, a through hole 22 is provided at the bottom of the slide groove 21, a fixing hole 311 is provided on the lower surface of the slider 31, a locking bolt 32 is movably connected to the inside of the through hole 22, the end of the locking bolt 32 passes through the through hole 22 and extends to the inside of the fixing hole 311, and the locking bolt 32 is threadedly connected to the fixing hole 311; through such an arrangement, the fixing seat 2 and the base plate 3 adopt a detachable structure, which is convenient for subsequent maintenance and replacement.

[0029] Furthermore, two groups of rotating seats 33 are fixedly connected to one side of the upper surface of the base plate 3, and a rotating buckle 41 is fixedly connected to the outer side of the hook-type mounting seat 4 and located below the second connecting seat 42, and the rotating buckle 41 is rotatably connected to the inner side of the two groups of rotating seats 33; the hook-type mounting seat 4 forms a rotating structure with the rotating seat 33 through the rotating buckle 41, so that the inclination angle of the hook-type mounting seat 4 is in an adjustable state to adapt to different attachment angles with the belt.

[0030] Furthermore, two groups of limiting ribs 43 are fixedly connected to the inner wall of the hook-type mounting seat 4, and two groups of limiting grooves 61 are opened on one side of the scraper 6. The two groups of limiting ribs 43 are respectively slidably connected to the inside of the limiting grooves 61 on the corresponding side; when installing the scraper 6 inside the hook-type mounting seat 4, it is only necessary to insert the limiting grooves 61 into the outside of the limiting ribs 43 to quickly and conveniently complete the scraper 6 positioning operation, and the position of the limiting ribs 43 and the limiting grooves 61 are coordinated to play a role in lateral limiting of the scraper 6.

[0031] Furthermore, two groups of movable holes 44 are formed through the other side of the outside of the hook-type mounting seat 4, and two groups of connecting holes 62 are formed on the other side of the scraper 6. The movable holes 44 are movably connected inside with fixing bolts 63. The ends of the fixing bolts 63 pass through the movable holes 44 and extend to the inside of the connecting holes 62. The fixing bolts 63 are threadedly connected to the connecting holes 62. The scraper 6 is fixed to the hook-type mounting seat 4 by the fixing bolts 63. When disassembling and assembling the scraper 6, it is only necessary to adjust the state of the fixing bolts 63 to quickly complete the disassembly and assembly of the scraper 6.

[0032] Furthermore, the lower end of the adjusting rod 7 is fixedly connected to a knob 71, and the upper end of the adjusting rod 7 is fixedly connected to a limiting seat 72; by rotating the adjusting rod 7, the height of the limiting seat 72 can be changed, thereby indirectly adjusting the inclination angle of the hook type mounting seat 4 (it should be noted that when the scraper 6 is installed in contact with the belt, the limiting seat 72 is located below the inclined surface of the hook type mounting seat 4, and it is necessary to ensure that the upper surface of the limiting seat 72 does not contact the inclined surface of the hook type mounting seat 4. The purpose of doing this is that when the scraper 6 contacts the belt, the tension spring 5 can exert its elastic force to firmly attach the scraper 6 to one side of the belt through the elastic force).

[0033] Furthermore, the limiting seat 72 is made of rubber material; the limiting seat 72 made of rubber material reduces the wear when contacting with the hook type mounting seat 4.

[0034] Working principle: When the scraper 6 is worn and needs to be replaced, the knob 71 can be manually rotated first, and the knob 71 drives the adjustment rod 7 to rotate inside the threaded hole 35, and the adjustment rod 7 drives the limit seat 72 to move upward. As the limit seat 72 continues to move upward, the limit seat 72 will abut against the hook-type mounting seat 4 and the scraper 6 to change the angle until the scraper 6 and the belt are separated. Then, the fixing bolt 63 is unscrewed to remove the scraper 6 from the hook-type mounting seat 4.

[0035] When the remaining components on the single-group base plate 3 need to be replaced, it is only necessary to unscrew the locking bolt 32 and then remove the slider 31 corresponding to the lower surface of the base plate 3 from the inside of the fixing seat 2 without the need for overall disassembly.

[0036] During the belt transportation process, each set of scrapers 6 can be firmly attached to one side of the belt through the elastic tension of the tension spring 5. As the belt moves, each set of scrapers 6 can fine-tune the inclination angle according to the flatness of the belt surface to ensure that each set of scrapers 6 is always attached to the belt.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
