Conveying device capable of automatically adjusting belt tension according to weight of materials

Abstract

The invention relates to the technical field of conveyors, and discloses a conveying device capable of automatically adjusting the belt tension according to the weight of materials. The conveying device comprises a rack, wherein a driving groove is formed in the top of the rack, a rack is fixedly connected to the inner bottom of the driving groove, a gear is engaged with the top of the rack, a rotating wheel is fixedly connected to the interior of the gear, a movable frame is fixedly connected to the top of the rotating wheel, a support rod is connected to the interior of the movable frame ina sliding mode, a band pulley is fixedly connected to the back surface of the support rod, a conveying belt sleeves the outer side of the band pulley, a catch pawl is connected to the interior of theconveying belt in the sliding mode, and tension springs are fixedly connected to both sides of the bottom of the catch pawl. According to the conveying device capable of automatically adjusting the belt tension according to the weight of the materials, a piston is pressed to move leftwards by the materials, an expansion ball is driven to expand by the piston, and the expansion ball is matched withthe catch pawl, so that the effect that heavy objects can be effectively conveyed and cannot fall off is achieved.

Description

technical field [0001] The invention relates to the technical field of conveyors, in particular to a conveyor device that can automatically adjust belt tension according to material weight. Background technique [0002] Conveyors have a long history. In ancient China, people used high-drum cars and water-lifting rollovers to transport water. This was the prototype of early conveyors. Conveyors can be divided into: integrated conveyors for loading and refilling, and belt conveyors according to their operation methods. Conveyors, screw conveyors, bucket elevators, roller conveyors, plate chain conveyors, mesh belt conveyors and chain conveyors, among which belt conveyors are currently the main way of conveying bulk materials. [0003] The belt conveyor is a machine that transports materials in a continuous manner driven by friction. The existing belt conveyor can only transport light materials. When heavy materials need to be sent from a low place to a high place, the belt is ...
