Concrete pump truck hopper metering device

Abstract

The invention discloses a concrete pump truck hopper metering device. The metering device comprises a hopper body, a metering cylinder, weighing sensors, a guide rail and a PLC controller, wherein the metering cylinder is arranged in the hopper body, metering cylinder support legs are installed at four corners of the bottom of the metering cylinder, the weighing sensors are correspondingly arranged right below the metering cylinder support legs, weighing sensor fixing plates are arranged at the bottoms of the weighing sensors, the weighing sensor fixing plates are welded to the inner wall of the hopper body, the bottom end of the metering cylinder is connected with a conical hopper, a discharging pipe is installed at the bottom end of the conical hopper, and a discharging electromagnetic valve is installed on the discharging pipe. According to the metering device, by arranging the metering cylinder, the weighing sensors, the guide rail, a first sliding door and a second sliding door, the problems that an existing concrete pump truck hopper does not have the function of automatically metering poured concrete, personnel cannot accurately grasp the concrete dosage, excessive pouring is likely to be caused, and resources are wasted are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a metering device for a hopper of a concrete pump truck. Background technique [0002] In the process of building construction, concrete needs to be poured in the fixed formwork, and the formwork will be removed after the concrete is formed and solidified to a certain strength. The large-scale pouring of concrete is completed by a concrete pump truck. The machine for conveying concrete continuously along the pipeline is composed of a pump body, a conveying pipe and a hopper. For other auxiliary devices, the power of the concrete pump truck transmits the power of the engine to the hydraulic pump group or the rear axle through the power transfer case. The concrete poured into the hopper is conveyed to a certain height and distance. However, the function of the hopper of the existing concrete pump truck is too single to measure the concrete poured into the hopper. The...
