A concrete mixing station hoisting material truck with a material door mechanism

Abstract

A concrete mixing plant lifting skip with a material door mechanism belongs to the technical field of skip lifting type concrete mixing plants. The concrete mixing plant lifting skip comprises a skip body, wherein a material door is arranged at the discharge opening of the skip body; a material door support arm is arranged on the material door adopting a cutting type material door structure; the material door is equipped with a material door actuation mechanism; the material door actuation mechanism comprises a cylinder, a cylinder rocker arm and a material door driving lever; one end of the cylinder is mounted on a mixing plant main body framework through a fixing seat; the cylinder is hinged to the fixing seat; the other end of the cylinder is hinged to one end of the cylinder rocker arm; the other end of the cylinder rocker arm is mounted on a lower-layer guide rail through a driving lever rotating shaft; the cylinder rocker arm is in key joint with the driving lever rotating shaft; one end of the material door driving lever is mounted on the lower-layer guide rail through the driving lever rotating shaft; the material door driving lever is in key joint with the driving lever rotating shaft; the other end of the material door driving lever corresponds to the material door support arm. According to the invention, the waiting time of a mixing engine can be shortened, the production efficiency is improved, and the service life of the concrete mixing plant lifting mechanism and the equipment running security are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of a concrete mixing station with lifting trucks, and in particular relates to a lifting truck of a concrete mixing station with a material door mechanism. Background technique [0002] The aggregate conveying process of the feed truck lifting concrete mixing plant is as follows: first, the aggregates of various specifications are measured according to the specified mixing ratio, and then the measured aggregate is transported to the lifting feed truck through the belt conveyor, and the material is lifted The car will be lifted from the receiving level of the material truck to the unloading level of the material truck and unloaded. After the unloading is completed, the lifting material truck will return to the material receiving level of the material truck to complete a working cycle. [0003] Obviously, in the whole working cycle process, the continuity of each link in the working cycle is an important facto...

AI Technical Summary

Problems solved by technology

Although this lifting method is helpful to improve production efficiency, it does not fundamentally avoid the waiting problem of the mixing main engine, and each working cycle needs to lift the material truck for a second start after hovering in the middle of the operating position. For this For a large-scale concrete mixing plant, the hoist of the hoisting mechanism is frequently started with heavy loads, which will directly lead to a greatly shortened service life of the hoisting wire rope, and virtually reduces the safety factor during the operation of the equipment.
