A belt conveyor

Abstract

The invention discloses a belt conveyer. The belt conveyer comprises a frame and a conveying belt; the frame is provided with a main roller, a driven roller and a support cylinder; the conveying belt sleeves the main roller and the driven roller; the rotating shaft of the main roller penetrates one end of the support cylinder and is rotatably arranged inside bearings and connected with a cylinder cutter, which is parallel to the rotating shaft, through a linkage mechanism. The belt conveyer also comprises a V-shaped blade which is fixed onto the support cylinder through a connecting rod, the V-shaped blade is in an arc shape matched with the outer surface of the main roller, the cross section of the V-shaped blade is provided with a wheel, and when in work, the wheel is in contact with the conveying belt on the main roller; the driven roller is provided with a tensioning mechanism. When the main roller fails and leads to vertical vibration of the conveying belt, the wheel mounted on the cross section of the V-shaped blade is in contact with the conveying belt, so that damage to the V-shaped blade due to too much contact between the V-shaped blade and the conveying surface of the conveying belt can be effectively avoided, and further the service life of the conveying belt can be prolonged.

Description

technical field [0001] The invention relates to a conveyor, in particular to a belt conveyor. Background technique [0002] The belt conveyor is a friction-driven machine that transports materials in a continuous manner. It can form a material conveying process on a certain conveying line from the initial feeding point to the final unloading point. It can not only transport broken materials, but also transport finished items; in addition to pure material transport, it can also cooperate with the requirements of the technological process in the production process of various industrial enterprises to form a rhythmic flow operation transport line. [0003] Belt conveyor is also called conveyor belt conveyor. The conveyor belt moves according to the principle of friction transmission. It is suitable for conveying powdery, granular and small pieces of low-grinding materials with a bulk density of less than 1.67 / ton / m3 and easy to dig out. Bagged materials, such as coal, gravel,...

AI Technical Summary

Problems solved by technology

[0004] In the long-term working state of the conveyor belt conveyor, more material residues will accumulate on the conveying surface of the conveyor belt, and the remaining materials will adhere to the conveying surface and rotate with the conveyor belt, which greatly increases the workload of the driving roller when it rotates. And the residual material will not slide down to the destination together with the material. While reducing the effective conveying capacity, it will also cause a certain degree of damage to the conveyor belt; at present, when cleaning the residual material on the surface of the conveyor belt, more use Alloy scraper, sticking it to the surface of the conveyor belt, under normal circumstances, this method can improve the cleaning effect, but when the main roller of the conveyor is in contact with the conveyor belt at the moment or the main roller fails and the conveyor belt stops suddenly, The conveyor belt will vibrate up and down to a certain extent, that is, it will move up and down. The scraper attached to the conveyor belt will directly generate force on the surface of the conveyor belt. When the main roller returns to normal, the scraper will directly rub against the conveyor belt, resulting in damage to the conveyor belt.
