AI Technical Summary

Technical Problem

Existing concrete sampling devices, when operated manually, are prone to issues such as insufficient filling or concrete spillage, failing to meet the requirements for quantitative sampling.

Method used

A concrete quantitative sampling device was designed, including a feeding support frame, a sampling funnel, a quantitative hopper and an excess material collection assembly. Quantitative sampling is achieved through an overflow section and a tilting section. Excess concrete is collected by an overflow trough. The walking section and the tilting section work together to move and tilt the quantitative hopper.

Benefits of technology

It enables quantitative sampling of concrete, avoiding insufficient sampling or overflow waste, improving sampling accuracy and efficiency, and reducing manual labor intensity.

Abstract

This invention discloses a concrete quantitative sampling device and method, including a discharge support frame, a sampling funnel, a quantitative hopper, and a residual material collection assembly. The sampling funnel is located at the top of the discharge support frame, and the quantitative hopper is located at the bottom of the sampling funnel. An overflow section is provided on the side of the quantitative hopper, and a tilting section is provided at the bottom of the quantitative hopper. A traveling section is provided at the bottom of the tilting section. The residual material collection assembly is located on the side of the discharge support frame. This invention utilizes the sampling funnel at the top of the discharge support frame to guide the concrete discharged from the mixer truck into the quantitative hopper. Excess concrete overflows from the overflow section into the residual material collection assembly. The traveling section moves the fully loaded quantitative hopper to the filling area, and the tilting section tilts the quantitative hopper to unload the concrete. This design utilizes the overflow design of the overflow section to maintain quantitative sampling by the quantitative hopper, avoiding the problems of insufficient concrete sampling or excessive spillage that are common with manual sampling.
