Description

Technical Field

[0001] The utility model relates to a belt cleaning assembly of a belt conveyor, belonging to the technical field of belt conveyor maintenance equipment. Background Art

[0002] In industrial production, belt conveyors are widely used for continuous conveying of various bulk materials. During the conveying process, inevitably, some residues of the materials will adhere to the belt. If these residual materials are not cleaned in time, it will affect the normal operation of the belt, such as increasing the risks of belt deviation and wear, reducing the conveying efficiency, and may also cause problems such as material spillage. In order to ensure the long-term stable operation of the belt conveyor and reduce equipment failures, it is necessary to clean the belt conveyor regularly.

[0003] There are certain limitations in the traditional manual cleaning method. In the early stage, methods such as manual cleaning may be adopted, but the efficiency is low and there are safety hazards. Therefore, specially designed mechanical cleaners have gradually emerged to address these problems. At present, although the existing blade-type belt conveyor cleaners also have a good cleaning effect on the belt conveyor, their installation methods are relatively limited, and they are basically applicable to be installed in relatively open places below the belt conveyor. Moreover, the materials cleaned by the blade-type belt conveyor cleaners will directly accumulate directly below the belt conveyor, which is likely to wear the belt conveyor. And when the blade-type cleaner is in contact with the belt conveyor, due to the deformation of the old belt, the belt conveyor cleaner cannot be closely attached to the belt, and there will be some situations where the cleaning is not in place. The scraper-type cleaner is mainly used for cleaning small particles and their media, can effectively ensure the cleanliness of the conveyor belt, has a novel structure, a unique buffer compensation device, good anti-impact and oscillation performance of the conveyor belt, good cleaning effect, and is not easy to damage the conveyor belt. However, it is relatively heavy, requires a certain amount of manpower and technology for installation and maintenance, and the cost is relatively high. For some highly viscous materials, there may be a certain amount of material sticking to the scraper. There is also the existing high-pressure water spraying cleaner, whose principle is to use high-pressure water to flush the belt to remove the adhered materials. This cleaning method has a good cleaning effect on the adhered bulk materials. Its disadvantage is that it will increase the humidity and viscosity of the materials, and it is necessary to install water pipes and pressurization devices, and the construction cost will be relatively high.

[0004] With the continuous progress of technologies such as materials science and mechanical design, it is very necessary to improve the performance of the belt conveyor cleaner and optimize its structure to adapt to different working conditions and material property requirements.

The diameter of the retaining cap 21 is larger than the diameter of the guide hole of the horizontal plate 18. The top of the guide post 19 is fixedly connected to the brush plate 8. The spring 20 is sleeved on the guide post 19 between the upper surface of the horizontal plate 18 and the lower surface of the brush plate 8. Under the action of the spring 20, the brush plate 8 always closely fits the belt, enhancing the cleaning effect on the belt. The front end of the guide post 19 has a thread, and a threaded hole is opened on the bottom surface of the brush plate 8.

The two lead screw nuts 14 cannot rotate under the constraint of the inner wall of the square sleeve of the fixed column 2, and can only move up and down along the two lead screws 13 respectively. When the lead screw nuts 14 move, they drive the sliding connection blocks 16 to slide synchronously in the opening grooves 3 of the column 2, and the sliding connection blocks 16 can drive the lifting plates 5 of the lifting frame to move;

[0033] The top plate 6 of the lifting frame drives the brush plate bracket 7 and the brush plate 8 of the cleaning mechanism to move to the height of the belt of the belt conveyor. Turn off the motor 12, move the moving base 1, so that the belt of the belt conveyor is located between the outer sleeve of the clamping shaft 22 and the brush plate 8, and prepare to clean the adhered materials on the belt by the brush plate 8;

[0034] Turn on the belt conveyor. The belt conveyor drives the belt to rotate. The spring 20 pushes the brush plate 8 to move upward. The brush plate 8 will drive the guide post 19 to slide inside the guide hole. Due to the action of the spring 20, the brush plate 8 will always closely fit the belt, further enhancing the cleaning effect on the belt.
