Multi-layer automatic sampling and accuracy improving soil sampler for soil remediation

Abstract

The invention relates to the technical field of ecological restoration, and discloses a multi-layer automatic sampling and accuracy improving soil sampler for soil remediation. The multi-layer automatic sampling and accuracy improving soil sampler comprises a shell, the shell is utilized to support and stabilize the whole device, through cooperative use of a sampling chamber, a push rod, a second disc, a first limiting sleeve and a baffle plate, the sampling chamber is automatically opened during sampling, after sampling is completed, the sampling chamber is automatically closed, cross contamination of soil at different depths is avoided, the accuracy of a soil sampling result is improved, through cooperative use of a convex disc, a rotating shaft, a first limiting sleeve, a second limiting sleeve and a roller shaft, the soil at different depths is automatically crushed and sampled, repeated sampling is not needed, more time and labor are saved, the working efficiency of sampling is improved, and the two steps of opening and closing and automatic sampling of the sampler are linked through cooperative use of a sliding sheet and a sliding rheostat, so that the linkage property of the whole device is improved, and the operation is simpler.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a soil sampler for multi-layer automatic sampling and improved accuracy for soil restoration. Background technique [0002] With the continuous development of agricultural technology, the problem of ecological pollution has gradually been paid attention to. Ecological restoration is a technical measure to restore the normal function of the polluted soil. The soil is one of the important components of the entire ecological environment. Soil pollution will make the ecological environment become Poor and need to remediate the polluted environment. Most of the pollution sources that cause soil pollution are different, and remediation and restoration are required according to different pollution sources. Therefore, it is necessary to take samples of the soil for testing, and then carry out special restoration. However, the current soil sampling device is relatively sim...

Problems solved by technology

However, the current soil sampling device is relatively simple to set up. In the process of sampling, the soil at different depths cannot be sampled at one time, and it needs to be operated many times, which is time-consuming and laborious. The surface usually adheres to soil at different depths, so there may be cross-contamination between soils, which will affect the sampling results

[0003] Aiming at the deficiencies of the prior art, the present invention provides a soil sampler for soil remediation with multi-layer automatic sampling and improved accuracy, which has the advantages of sampling at different depths and avoiding cross-contamination, and solves the problem that the existing sampling device is relatively simple to set. It ensures that the soil at different depths can be sampled at one time when the device is used for operation, which improves the sampling efficiency, and controls the opening and closing of the sampling device during sampling, thereby avoiding soil at different depths. Mutual pollution, improve the intelligence of the sampler when used
