Earthwork screw conveying device with blockage early-warning function

Abstract

The invention relates to the technical field of earthwork excavation, and discloses an earthwork screw conveying device with a blockage early-warning function. The device comprises a conveying unit, wherein a screw propeller is movably installed in the conveying unit, the left and right ends of the screw propeller are movably installed at the left and right ends in the conveying unit through bearings, a bearing plate is movably installed in the lower side of the conveying unit, and an early-warning device is fixedly installed on the lower side of the bearing plate. When the inner part of the screw conveying device is blocked, internal earthwork cannot be conveyed to the right end, so that the pressure of the internal bearing plate is increased; after the bearing plate is pressed, a springmechanism is compressed, and when the pressure reaches a certain level, a sensing part at the lower end of the spring mechanism can make contact with a triggering part; and after the sensing part is in contact with the triggering part, an electrical connection is generated, and an early-warning module gives an alarm, so that the effect of timely early warning when the conveying unit is blocked isachieved.

Description

technical field [0001] The invention relates to the technical field of earthwork excavation, in particular to an earthwork screw conveying device with a blockage early warning function. Background technique [0002] The screw conveyor is a kind of machine that uses the motor to drive the screw to rotate and push the material to achieve the purpose of conveying. Its main components are the rotating shaft and the screw blade welded on the rotating shaft. When working, the screw blade pushes the material for screw conveying. [0003] At the earthwork excavation site, due to some terrain and soil quality reasons, the engineering vehicles for earthwork transportation cannot reach, so it is necessary to use the screw conveyor to send the earthwork to the place where the earthwork transportation engineering vehicles can reach, but because the excavation site is generally not carried out The soil that has been hardened is relatively soft, so during the conveying process of the screw...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an earthwork screw conveying device with a blockage early warning function, which has the characteristics of preventing the support from subsidence and issuing an early warning in case of internal blockage, which solves the problem of the current existing screw conveyor. Subsidence is prone to occur in soft soil, and problems that cannot be detected in time due to internal blockage
