Engineering exploration soil sampling device capable of sampling deep soil by several times

Abstract

The invention relates to the technical field of soil sampling, particularly to an engineering exploration soil sampling device capable of sampling deep soil by several times. The engineering exploration soil sampling device comprises a soil sampling mechanism, which comprises a soil sampling main body, wherein a first soil sampling cylinder is inserted into one end of the soil sampling main body.By arranging the first soil sampling cylinder, the first lead screw, the first bevel gear, the second bevel gear, the second soil sampling cylinder and the side plate, a worker shakes a crank to enable a rocker to drive the second bevel gear, the second bevel gear drives the first bevel gear to rotate to drive the first lead screw to rotate, the first lead screw moves downwards at the moment so asto insert the first soil sampling cylinder into the soil, when the first soil sampling cylinder is inserted to half of the soil, the servo motor starts to rotate, the rotating rod drives the second baffle to rotate so as to make the second soil sampling cylinder be opened to carry out secondary sampling on deep soil, so that the accuracy of a detection result of the device is improved.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a soil sampling device used for engineering exploration and capable of sampling soil depth in stages. Background technique [0002] With the development of society, environmental pollution is becoming more and more serious. The soil contains more pollutants, which is not convenient for the production and development of plants, and reduces the microorganisms in the soil. In severe cases, it will cause a large number of plants to die, which will have a serious impact on greening. People need to sample and analyze the soil to find a reasonable solution. Therefore, the staff uses the soil sampling device to sample the soil, then tests the sample soil, and performs targeted soil remediation treatment. [0003] Most of the traditional soil sampling devices directly insert the soil sampling cylinder into the soil to be sampled, and then perform sampling treatment. However, when th...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of soil sampling device that can sample soil depth in batches for engineering exploration, to solve the problem that most of the traditional soil sampling devices proposed in the above-mentioned background technology are directly inserting the soil sampling cylinder into the soil that needs to be sampled. However, when the sampling cylinder is inserted into the soil, the upper layer of soil at the mouth of the sampling cylinder will be inserted into the depth together with the sampling cylinder, causing the deep sample soil to be mixed with the upper layer of soil, which is not convenient for sample detection, and now Some sampling devices are inconvenient for staff to operate
