Improved shaft-less screw conveyer

Abstract

An improved shaft-less screw conveyer comprises supporting legs, a U-shaped groove arranged on the supporting legs and a screw body arranged in the U-shaped groove. One end of the screw body is connected with a drive device. The U-shaped groove is provided with a cover plate. The end, close to the drive device, of the cover plate is provided with a feeding opening. Elastic connection pieces are arranged on the inner wall of the cover plate. The bottoms of the elastic connection pieces are provided with an anti-arch strip. The anti-arch strip is in contact with the screw body. A wear-proof lining body is arranged on the inner wall of the U-shaped groove. The end, far away from the drive device, of the U-shaped groove is provided with a discharging opening. The discharging opening is in a funnel shape. The improved shaft-less screw conveyer is scientific and reasonable in design, the shaft-less screw body can be prevented from arching, the screw body is prevented from being damaged, andthe improved shaft-less screw conveyer is convenient to clear.

Description

technical field [0001] The invention relates to a conveying mechanism, in particular to an improved shaftless screw conveyer. Background technique [0002] Shaftless screw conveyor is a kind of machine for conveying goods. Compared with the traditional shafted screw conveyor, it adopts a design without a central shaft, and uses a flexible integral steel screw to push materials without interference from the central shaft. For the conveyor belt Shaped and easy-to-wind materials have special advantages. [0003] The disadvantages of the shaftless screw conveyor are: first, the screw body is easy to wear during the process of conveying materials; second, the screw body is easy to arch during the rotation process, resulting in wear of the screw body. Chinese patent CN104627628A applies for a shaftless screw conveyor, which includes a body, an arc-shaped groove is arranged in the body, a shaftless screw is arranged in the groove, and a shaftless screw is arranged on both sides of...

[0003] The disadvantages of the shaftless screw conveyor are: first, the screw body is easy to wear during the process of conveying materials; second, the screw body is easy to arch during the rotation process, resulting in wear of the screw body

This method can indeed prevent the shaftless spiral from arching, but the disadvantage of this method is that the body has an arc groove, which is difficult to clean. In addition, once the shaftless spiral arches, it will seriously damage the spiral body
