Large-flexibility spiral conveyor with adjustable length

Abstract

The invention discloses a large-flexibility spiral conveyor with adjustable length. The conveyor comprises a support and a charging section with charging section flanges, wherein the support and the charging section are fixedly connected, the charging section is provided with a charging opening, and the end of the charging section is fixedly connected with an electric motor; an output shaft of theelectric motor is fixedly connected with a conveying spiral blade; a flexible section with two ends fixedly connected with flexible section flanges, and a rigid section with two ends fixedly connected with rigid section flanges are further included, the conveying spiral blade is rotatably supported in the rigid section through a ring frame, a universal section fixedly connected with the end extends out of the end of the rigid section, and the flexible section and the charging section are connected through the charging section flanges and the flexible section flanges. The rigid section and theflexible section are connected through the flanges at the ends, the universal sections are located in the flexible sections, the spiral conveyor has the larger flexibility, and the conveying part canconvey materials under the smaller bending curvature radius state.

Description

Technical field [0001] The invention relates to a screw conveyor, in particular to a screw conveyor with large flexibility and adjustable length, belonging to the technical field of screw conveyors. Background technique [0002] Ordinary screw conveyors use spiral blades that rotate on a linear axis in a straight tube shell to transport materials. Usually screw conveyors are used to transport granular solid materials, but they can also be used to transport liquids or mixtures of solids and liquids. For example, it is used to transport food waste, wood chips, grains, boiler slag, mud, concrete slurry, etc. The screw conveyor is usually driven by a motor at one end to rotate the spiral blades in the bearings at both ends of the straight tube shell. The conveying rate is proportional to the rotation rate of the screw blade shaft. The screw conveyor can be used for horizontal conveying of materials, and it can also convey materials upward at a certain inclination angle. Therefore...

AI Technical Summary

Problems solved by technology

This technical solution can make the conveying parts of the screw conveyor flexible to a certain extent, and can meet the needs of some materials conveying between two points when obstacles need to be bypassed, but it has the following disadvantages: When the flexible shell of the conveyor is relatively When bending with a small radius of curvature, the flexible shell will become flat and will be squeezed together with the conveying screw blade, resulting in a significant increase in the rotational resistance moment of the conveying screw blade, and even causing the conveying screw blade to fail to rotate

In addition, the conveying distance of this conveying device cannot be adjusted.
