Description

TECHNICAL FIELD

[0001] The utility model relates to a belt conveyor accessory technical field, concretely is a belt conveyor noise reduction mechanism. BACKGROUND

[0002] As a key material conveying equipment, the belt conveyor has too large running noise, which will affect the comfort of the working environment, and some parts, such as the motor and the transmission box, are provided with sound insulation materials and noise reduction structures to isolate and reduce the propagation of noise. However, the drum is also prone to generate relatively large noise during operation. Frequent noise and vibration problems can cause the equipment failure rate to rise, thereby increasing the cost of maintenance and replacement of parts.

[0003] For example, in the low-noise belt conveyor disclosed in the prior patent No. CN213801696U, a bottom plate and an installation plate located directly above the bottom plate are provided, a support frame is arranged between the installation plate and the bottom plate, the support frame is installed on the bottom plate, a connecting seat corresponding to the support frame is fixedly connected to the installation plate, the connecting seat is hingedly connected to the top end of the support frame, a conveyor belt is sleeved between the driven roller and the driving roller, a cleaning assembly is arranged below the conveyor belt close to the driven roller, and the cleaning assembly is installed on the rack. By arranging the cleaning assembly below the conveyor belt, the labor intensity is reduced, and the safety of the belt conveyor is ensured. By arranging the noise reduction shell with the sound absorbing layer and the sound insulation board outside the cleaning motor, the rotating motor and the driving motor, the noise of the motor during operation is effectively reduced.

[0004] In the above-mentioned belt conveyor, the sound absorbing layer and the sound insulation board are used for noise reduction, but the structure design for the drum is not convenient for disassembly and replacement, and noise is easily generated after long-term use and wear. In addition, the loose belt is prone to slip and deviation during operation, which aggravates the friction and impact between the belt and the drum, the carrier roller and other components, and significantly affects the overall performance and operation effect of the belt conveyor. In view of the above problems, a belt conveyor noise reduction mechanism is proposed. UTILITY MODEL CONTENTS
