Description

Technical Field

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

[0002] Belt conveyors are commonly used conveying equipment used in the field of mining production to transport materials. Its core component is a conveyor belt made of high-strength, wear-resistant material. This conveyor belt is wrapped around two or more rollers, and the rotation of the rollers drives the conveyor belt to move, thereby realizing continuous transportation of materials. During the operation of the belt conveyor, there may be material residue on the surface of the belt. When impurities are attached to the surface of the belt, these impurities will increase the friction between the belt and the rollers, causing the belt to deviate, increase wear, and even cause serious faults such as belt breakage. In the existing technology, a cleaner can be installed in the belt conveyor to clean the surface of the head belt to avoid the attachment of impurities on the belt surface. Traditional cleaners are mostly set under the head belt for cleaning. Some belt conveyors do not have enough internal space to install a cleaner. Secondly, only setting a single cleaner will result in poor cleaning effect. Utility Model Content

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0016] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4The utility model provides a technical solution: a belt cleaning device for a belt conveyor, comprising a steel pipe 1, which is rotatably connected to the cover body 8, and the cover body 8 is fixedly connected to the top of the belt conveyor body to shield and protect the conveyor belt at the head. The side wall of the cover body 8 is hinged with a switch door, which is used to repair and maintain the equipment assembled in the cover body 8. A U-shaped frame 2 is welded and fixed to the side wall of the steel pipe 1, and a scraper 3 is detachably fixed and assembled in the U-shaped frame 2 by fixing screws. The scraper 3 is fitted with the surface of the head belt to clean the surface of the belt and remove the residual material on the surface of the belt. The scraper 3 is detachably fixed and connected by fixing screws. When the scraper 3 is worn, it is convenient to maintain and replace the scraper 3. The steel pipe 1 is combined with the U-shaped frame 2 as the main structure of the device, which has a lighter weight and is convenient to adjust the inclination angle of the U-shaped frame 2 so that the scraper 3 can maintain a fit with the belt surface.

[0017] The two ends of the steel pipe 1 pass through the two side walls of the cover 8 respectively, and the two ends of the steel pipe 1 are respectively welded with movable arms 4, which are L-shaped. The movable arm 4 and the U-shaped frame 2 of the fixed scraper 3 form a skewed Y-shaped structure. The movable arm 4 is welded by two steel plates. The size of the steel plate in the reverse belt running direction is 500mm*100mm, and the size of the steel plate in the forward belt running direction is 650mm*100mm. One end of the movable arm 4 in the forward belt running direction is fixedly equipped with a counterweight assembly 5, and the side wall of the cover 8 is fixedly equipped with The limiting component 6 limits the end of the movable arm 4 in the opposite direction of the belt running direction. The counterweight component 5 is provided to drive the steel pipe 1 to rotate through the movable arm 4, and tighten the steel pipe 1 and the U-shaped frame 2, thereby maintaining the inclination state of the scraper 3 and the belt surface. The inclination angle of the movable arm 4 can be limited by the provided limiting component 6 to prevent the movable arm 4 from being too tilted, causing the belt surface to bear excessive gravity from the scraper 3 and the U-shaped frame 2, so that the scraper 3 affects the normal transportation of materials by the belt.

[0018] like Figure 2 and Figure 4 As shown in the figure, the counterweight assembly 5 includes a counterweight rod 51, one end of the counterweight rod 51 is welded and fixed to the side wall of the movable arm 4, and the other end of the counterweight rod 51 is welded and fixed with a fixing pin 52, and the outer side wall of the fixing pin 52 is sleeved with a counterweight block 53. By setting the counterweight block 53, the steel pipe 1 and the U-shaped frame 2 are driven to rotate inside the cover body 8 through the movable arm 4 to adjust the angular position of the U-shaped frame 2. The counterweight rod 51 is L-shaped and is distributed around the switch door. When the scraper 3 is maintained and replaced, the counterweight rod 51 will not block the switch door, thereby causing inconvenience in repair and maintenance.

[0019] like Figure 2 and Figure 3As shown in the figure, the limiting assembly 6 includes a fixing nut 61, and a connecting frame 62 is welded and fixed to the side wall of the fixing nut 61. The connecting frame 62 is welded and fixed to the side wall of the cover body 8. The limiting bolt 63 is threaded inside the fixing nut 61. By screwing the limiting bolt 63 inside the fixing nut 61, the bottom of the limiting bolt 63 can limit the rotation angle of the movable arm 4, so that the movable arm 4 can be deflected within a certain range, avoiding the deflection angle of the movable arm 4 being too large, causing the scraper 3 to affect the normal operation of the belt.

[0020] like Figure 2 and Figure 3 As shown in the figure, an auxiliary tensioning assembly 7 is installed between the side wall of the cover body 8 and the movable arm 4. The auxiliary tensioning assembly 7 cooperates with the counterweight assembly 5, and a double tensioning method is adopted to better drive the movable arm 4 and the U-shaped frame 2 to deflect, thereby improving the effect of the scraper 3 fitting the belt surface.

[0021] The auxiliary tensioning assembly 7 includes a hook 71, which is welded and fixed to the side wall of the cover body 8. An open groove is provided on the side wall of the movable arm 4. A tensioning belt 72 is sleeved between the hook 71 and the open groove. The rotation angle of the movable arm 4 is further tightened and adjusted by the set tensioning belt 72.

[0022] Working principle: Figure 1 and Figure 2 As shown in the figure, the device is assembled inside the cover 8. Through the cooperation of the counterweight assembly 5 and the movable arm 4, the U-shaped frame 2 can be deflected in the inner cavity of the cover 8, and the scraper 3 is kept in contact with the surface of the belt. The surface of the belt is cleaned by the scraper 3 to remove the residual material. The device can be used in conjunction with a traditional belt cleaner assembled under the belt to better clean the surface of the belt and improve the cleaning effect. At the same time, when the installation position inside the belt conveyor is limited and the traditional belt cleaner cannot be assembled under the belt, the device can be assembled independently to clean the belt above the belt to maintain the cleaning effect of the belt surface.
