Description

Vibration and noise reduction structure of grain and oil conveying equipment Technical Field The utility model relates to the technical field of grain and oil conveying noise reduction, in particular to a vibration reduction and noise reduction structure of grain and oil conveying equipment. Background Scraper conveyors occupy an important position in grain and oil transportation. However, in use of the scraper conveyor, the frictional impact between the scraper and the chute can produce intense noise. In the current equipment, the chute structure is a fixed U-shaped shell, when the scraper blade conveys materials, frequent friction is generated between the edge of the bottom of the scraper blade and the bottom of the chute, which is an important noise source, and meanwhile, quite large noise is generated when grain particles move in the chute. In order to reduce noise, some manufacturers set flexible rubber strips at the bottom of the scraper, but the rubber strips are easy to wear and fail under high-strength friction. In order to solve the noise problem, the whole conveyor is covered by a box body in the traditional mode, but the symptoms and the root causes are not treated. For this problem, patent document CN220448878U discloses a coal mine conveyor with a noise reduction function, which attempts to achieve noise reduction by spring vibration reduction, and the spring vibration reduction cannot solve the problem of collision noise between a scraper and a chute at all. In order to solve the problem, a vibration and noise reduction structure of grain and oil conveying equipment is provided, and noise in grain and oil conveying can be greatly reduced. Disclosure of utility model Aiming at the situation, in order to overcome the defects of the prior art, the utility model provides the vibration and noise reduction structure of the grain and oil conveying equipment, which effectively solves the problems of avoiding drug infection and avoiding liquid medicine sprinkling. The technical scheme includes that the chute comprises a chute body, wherein roll shafts are arranged at two ends of the chute body, the roll shafts are conveyed by a conveying belt, the running speed of the conveying belt is equal to the moving speed of a scraper in a scraper conveyor, a horizontal supporting plate is arranged in the chute body, the upper half part of the conveying belt is kept horizontal by the supporting plate, and a tensioning roller is arranged at the lower side of the chute body. Preferably, the U-shaped plate with a downward opening is arranged below the body, the tensioning roller is rotatably arranged in the U-shaped plate, a plurality of inserting rods are arranged at the upper end of the U-shaped plate, a plurality of cylinders corresponding to the inserting rods one to one are fixed at the lower end of the body, the inserting rods are arranged in the cylinders, and the pressure springs are arranged in the cylinders. Preferably, stainless steel is paved on the outer surface of the conveyor belt. Preferably, the section of the conveyor belt is U-shaped, and two sides of the conveyor belt are attached to the side plates of the body. The utility model has ingenious structure, and the bottom of the chute and the scraping plate move simultaneously by changing the traditional fixed chute into the movable chute, so that the friction between the scraping plate and the chute can be reduced, and the purpose of noise reduction is further realized.
