Description

Soil sampling device

Technical Field

The utility model relates to a sampling device technical field, in particular to soil sampling device.

Background

In order to detect the soil, sampling inspection needs to be carried out on the soil. In the soil sampling process, a soil sampling device is required to be used for collecting soil samples on the surface layer of the farmland or wasteland, and a small iron shovel can be used. The cutting ring can be used for researching general physical properties of soil, such as soil volume weight, porosity, water retention property and the like. The cutting ring is a cylinder with openings at two ends, the lower opening is provided with a blade, and the height and the diameter of the cylinder are both about 5 cm. When a soil sample for chemical analysis or physical analysis without undisturbed soil is collected, an open-type soil drill is used, and the soil drill is divided into two types, namely manual operation and mechanical operation.

The open type soil that current manual pushed down bores the structure and mainly includes the drilling rod and sets up the drill bit at the cell type of drilling rod one end, when the soil drill used, with whole drilling rod perpendicular ground then push down, pull out the drilling rod again after pushing down the drill bit that fetches earth to predetermineeing the degree of depth, the soil sample is extruded in the drill bit that fetches earth, accomplishes the sample operation of soil sample.

However, because the sample in the drill bit starts to be pressed down from the soil surface layer, the sample in the drill bit actually samples downwards from the soil surface layer, and the volume of the sample in the drill bit is determined according to the volume of the drill bit, when the preset depth is reached on the drill rod, the soil sample in the drill bit cannot be compacted in the drill bit, and the problem that the existing soil drill cannot conveniently sample the soil with the preset depth is caused.

In order to solve the problems, the existing method can firstly remove a part of the soil on the upper layer of the soil and then carry out sampling operation through the operation of firstly perforating and then sampling. Because the soil auger sampling is through pushing down the sample, the drill bit has more soil sample of non-preset degree of depth all the time, when carrying out chemical analysis, all has inaccurate problem. In order to ensure the accuracy of chemical analysis, pit excavation sampling is usually adopted, but the pit excavation sampling operation is complicated and has large workload, so that the pit excavation sampling operation is not suitable for quick sampling operation, and therefore, the soil sampling device capable of sampling a preset depth in a small range (with small depth range change) is required to be provided at present.
