AI Technical Summary

Technical Problem

During the sampling process, the existing sampling devices cannot effectively slump during sampling due to the increase in the compactness of the material during sampling, which affects the sampling efficiency. The structure of the sampling port is lacking, so the accuracy of the sampling sample cannot be guaranteed.

Method used

An engineering sampling device is designed, including a sampling rod, a sampling cylinder, a sampling assembly, an injection control assembly and an auxiliary sampling assembly. By setting up a sampling port baffle and guide slider, the sampling port is closed and the cement is prevented from spilling; the eccentric wheel is driven by the motor to generate vibration to help the cement slump into the sampling barrel.

Benefits of technology

It improves sampling efficiency and accuracy, and can quickly and effectively sample bagged or canned cement, prevent cement from spilling, and achieve fixed-depth sampling to ensure the accuracy of the test results.

Abstract

The utility model discloses an engineering sampling device, which belongs to the technical field of detection equipment for engineering supervision and comprises a sampling rod and a sampling mechanism, and the sampling mechanism is arranged in the sampling rod and comprises a sampling barrel, a sampling component, a sampling control component and an auxiliary sampling component; when the sampling device is inserted into bagged or canned cement, the sampling opening faces upwards to enable the cement to fall into the sampling barrel, the motor drives the rotating rod to enable the eccentric wheel to rotate, and the sampling rod vibrates through the eccentric wheel to enable the cement to fall into the sampling barrel, so that the bagged or canned cement is quickly sampled; according to the cement sampling device, the opening can scatter cakes in bagged or canned cement, the sampling opening baffle can protect the cement in the sampling barrel through cooperation of the guiding sliding block and the sliding groove, the bagged or canned cement can be rapidly sampled, the sampling effect of the device is improved, and fixed-depth sampling can be achieved; the sampling device solves the problems that an existing sampling device cannot perform quick sampling and ensure the accuracy of a sampled sample.
