Soil sampling device for preventing disturbance damage to soil sample layer during sampling separation

Abstract

The invention provides a soil sampling device for preventing disturbance damage to a soil sample layer during sampling separation, relates to the field of soil sampling, and solves the problem that disturbance to a soil sample cannot be reduced by adopting a pricking type sampling structure so as to improve the sampling precision. When samples are taken out of the sampling barrel, most of the samples are taken out by adopting a crushing method, so that complete reservation of the soil samples cannot be realized, and the storage and reservation of the samples are influenced. The invention discloses a soil sampling device for preventing disturbance damage to a soil sample layer during sampling separation. The soil sampling device comprises a frame body adjusting groove and a sampling cylinder B, the frame body is of a concave structure, and two fixing bases are fixedly connected to the frame body through bolts. When the sampling cylinder B moves upwards by 10cm along with the electric telescopic rod, the top end surface of the sampling cylinder B is in contact with the top end surface of the shifting plate, and when the sampling cylinder B continuously moves upwards along with the electric telescopic rod, the sampling cylinder B is in a dismounting state, so that the sampling cylinder B can be automatically dismounted through the contraction of the electric telescopic rod.

Description

technical field [0001] The invention belongs to the technical field of soil sampling, and more specifically relates to a soil sampling device that prevents soil sample layers from being disturbed and damaged when sampling is separated. Background technique [0002] A soil sampler is a tool used to obtain soil samples. Commonly used are earth drills, shovels and shovels. Earth drills consist of a bit and handle made of a hard material (steel or hard plastic). Bits are usually helical or cylindrical. [0003] Such as the application number: CN201210092840.6, a mechanical soil sampling device, including a motor, a soil sampling drill, a soil collection disk and a fixed box, the lower end of the soil sampling drill is provided with a spiral inner groove, and the outer edge of the groove has an outer The small flange is extended, and the bottom end of the sampling drill is made into a pointed round drill surface. The upper end of the soil sampling drill is provided with a pass...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a soil sampling device that prevents the disturbance and damage of the soil sample layer when sampling is separated, to solve the existing problem that the above-mentioned application has a large disturbance to the soil during sampling, and it is easy to This leads to mixed phenomenon in the samples, and the sampling accuracy is low, and it is not possible to use the plunge-in sampling structure to reduce the disturbance to the soil sample and improve the sampling accuracy; moreover, the existing plunge-in sampling device combines the sampling cylinder and the The sample is extracted from the soil, and when the sample is taken out of the sampling cylinder, it is mostly taken out by a broken method, so that the complete retention of the soil sample cannot be achieved, which affects the storage and retention of the sample; finally, the existing cylindrical When the sampling cylinder is pulled out from the soil, the soil is easy to fall from the sampling cylinder, which affects the sampling success rate
