Soil sampler

Abstract

The invention provides a soil sampler, in particular a soil sampler applicable to hard or loose soil. The soil sampler consists of a back propping element, a transmission unit, a sampling head and a front propping element. The soil sampler can sample easily in the hardened soil; the sampling head is provided with a soil sample cutter; when a soil sample is put into a sampling box, the sample and the soil in the sampling box are completely separated by the soil sample cutter so as to ensure that the sample does not slip; the soil sampler can sample in the loose soil where the sample is difficult to form; the sampling head is provided with a plurality of sampling box chambers so as to ensure that the soil sample is finely layered and a plurality of samples can be sampled at the same time; the bottom section of the sampling box chamber is reserved with gaps, simultaneously the side wall of the sampling box chamber is provided with a partition table and the bottom of the sampling box chamber is provided with vent holes so as to ensure that the internal and external pressures are balanced when the sample is introduced into the sampling box, the soil is not disturbed, and in-situ sampling is realized; and the volume and weight of the sampling box are definite and convenient for measuring the volume weight of the soil sample.

Description

technical field [0001] The invention relates to a soil sampler, in particular to a soil sampler suitable for hard or loose soil. Background technique [0002] At present, the known soil samplers are classified according to the type of power drive, and are divided into manual soil samplers and mechanical soil samplers. Its basic structure is composed of sampling head, connecting rod and power drive unit. The driving unit of the manual soil sampler is a handle, the driving unit of the mechanical soil sampler is an electric motor, etc. The operation process is to insert the sampling head vertically into the soil, then press the soil into the sampling head by pressing down, turning, etc., and finally pull the soil sample out of the soil layer by lifting, rotating, etc., and then separate the soil sample, and complete the process. sampling. When the manual soil sampler is lifted up to extract the sampler from the soil, it is laborious and time-consuming, and sometimes even the...

AI Technical Summary

Problems solved by technology

The mechanical soil sampler has a complex structure, is difficult to maintain, has a large volume and weight, and requires additional power resources, so it is not suitable for carrying and using in the field

Manual soil samplers and mechanical soil samplers are suitable for limited soil quality, especially when sampling in dry hard compacted soil or loose soil, the soil sample is difficult to shape and easily slips from the soil sampling head, making it difficult to complete the sampling

The soil samples collected by the two soil samplers are rough, and the soil samples cannot be accurately stratified and sampled
