Problems solved by technology

[0003] During the use of existing soil sampling devices, it is often necessary to drill holes in the ground through motors and other devices and then take samples. The depth that needs to be sampled is inserted into the soil for sampling. When this method is used, in order to facilitate insertion into the soil at a certain depth, it is usually used to insert the hollow tube directly into the soil, or insert it into the soil in a spiral manner. The method is single and inconvenient. Fix the sampling device stably at the sampling site, and after sampling, due to the problem of soil material, it is easy to appear that after the plunger pulls out the soil, the sampled soil falls out of the hollow tube, which affects sampling. For this reason, a new type of soil is needed. Soil sample collection device with controllable depth range

Abstract

The invention relates to the technical field of soil detection, and discloses a depth-range-controllable soil sample collection device which comprises a sampling insertion rod; the bottom end of the sampling insertion rod is a tip end, the sampling insertion rod is of a hollow structure with both the top end and the bottom end being open, and the top end of the sampling insertion rod is fixedly connected with a rotating block; and a penetrating through hole is formed in the center of the upper surface of the rotating block, and the bottom end of the through hole is communicated with the interior of the sampling insertion rod. According to the device, through an arranged positioning insertion rod, the positioning insertion rod can be inserted into soil by treading a foot rest lever, the foot rest lever is supported by an arranged triangular rib plate, the problem of treading breakage can be prevented, and after the positioning insertion rod is inserted into the soil, the triangular rib plate also goes deep into the soil to prevent the positioning insertion rod from rotating in the soil; therefore, a rotating block can be held by hand to drive the sampling insertion rod in threaded connection with a threaded sleeve to rotate, and the descending position is controlled according to the sampling depth.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a soil sample collection device with a controllable depth range. Background technique [0002] With the continuous acceleration of the industrialization process, the unreasonable mining of mineral resources and their smelting discharge, long-term sewage irrigation of the soil, atmospheric subsidence caused by human activities, and the application of chemical fertilizers and pesticides have caused serious soil pollution, air pollution, Problems such as water pollution and waste pollution are generally more intuitive and can be found through the senses, while soil pollution is concealed and hysteresis, which can only be discovered through analysis of soil samples and crop residue detection. The laboratory often needs to test and analyze the soil after collection. For shallow soil, it is generally collected directly with tools such as shovels. To understand the pollution of d...
