Concrete finished product hopper combined discharge valve

Abstract

The invention provides a concrete finished product hopper combined discharge valve, and relates to the technical field of discharge valves. The concrete finished product hopper combined discharge valve comprises a raw material hopper and a vertical discharge valve which are sequentially arranged up and down, the raw material hopper is in the shape of an inverted circular truncated cone, both the top and the bottom of the vertical discharge valve are open, the lower end of the raw material hopper is connected with the top of the vertical discharge valve through a flange, an arc-shaped valve plate and a movable chute are sequentially arranged on the peripheral side of the vertical discharge valve from inside to outside, the arc-shaped valve plate comprises a left side plate, a right side plate and an arc-shaped bottom plate, the left side plate and the right side plate are both of fan-shaped hollowed-out structures, the circle centers of the left side plate and the right side plate are rotationally connected to the opposite outer walls of the vertical discharge valve through rotating shafts, the arc-shaped bottom plate is arranged between an arc-shaped edge of the left side plate andan arc-shaped edge of the right side plate and located at the bottom of the vertical discharge valve. The concrete finished product hopper combined discharge valve has the advantages that the phenomena of slurry leakage and material leakage when the discharge valve is closed can be avoided, concrete slurry splashing can be avoided when concrete mixers of different heights are fed, and the like.

Description

technical field [0001] The invention relates to the technical field of unloading valves, in particular to a combined unloading valve for concrete finished buckets. Background technique [0002] The function of the finished hopper loading and unloading valve is to load the concrete slurry in the finished hopper into the concrete mixer truck through the control unloading valve. At present, most of the discharge valves at the bottom of the finished hopper are straight cylinders. When unloading, the concrete slurry moves vertically downward into a free-falling body and enters the concrete mixer truck, causing the concrete slurry to splash when unloading, and the splashed part falls. Outside the body of the concrete mixer truck; when the material is unloaded quickly, part of the concrete slurry will overflow the hopper of the transport vehicle and fall to the ground, causing environmental pollution. Moreover, the height of concrete mixer trucks is inconsistent, some are as high ...

AI Technical Summary

Problems solved by technology

At present, most of the discharge valves at the bottom of the finished hopper are straight cylinders. When unloading, the concrete slurry moves vertically downward into a free-falling body and enters the concrete mixer truck, causing the concrete slurry to splash when unloading, and the splashed part falls. Outside the body of the concrete mixer truck; when the material is unloaded quickly, part of the concrete slurry will overflow the hopper of the transport vehicle and fall to the ground, causing environmental pollution

Moreover, the height of concrete mixer trucks is inconsistent, some are as high as 4.2m, some are as low as 3.8m, and the drop is as high as 400mm. It will make part of the concrete slurry splash when unloading. Therefore, there is an urgent need for a discharge valve that can solve the above problems.
