Soil sampler

Abstract

The invention relates to a soil sampler. The soil sample comprises a soil sampling pipe which is provided with a soil sampling chamber, wherein ventilating holes which communicates with the oil sampling chamber are distributed in the wall of the soil sampling pipe; a communicating chamber which communicates with the soil sampling chamber is arranged in the upper part of the soil sampling pipe; hanging holes which communicate with the communicating chamber are formed in the wall of the soil sampling pipe; a cushion is arranged in the soil sampling chamber. The soil sampler further comprises a connecting rod and an electric pike; the lower part of the connecting rod can pass through the communicating chamber; a retaining shoulder for limiting and applying force to the soil sampling pipe is arranged at the lower part of the connecting rod; a locking mechanism which is in locking connection with the upper end of the connecting rod is arranged at the lower end of the electric pike. With the adoption of the soil sampler, the completeness of a soil sample can be effectively improved, and the soil sampling efficiency can be greatly improved; the soil sampler is convenient to operate and carry; the soil sampler is obviously superior to a traditional mode and method.

Description

technical field [0001] The invention relates to a soil sampling device, in particular to a soil fetcher. Background technique [0002] In agricultural soil science research, it is necessary to obtain undisturbed soil samples through soil fetchers for analytical testing of field soils. Existing soil extractors are mainly divided into two types: rotary type and direct pressure type. [0003] When the rotary soil fetcher is fetching soil, due to the viscosity of the soil, the head is prone to blockage, so the soil fetching depth is limited each time, and the work efficiency is low. [0004] Most of the direct-pressure soil extractors use manual soil extraction. Conventionally, one person supports the soil extractor while the other beats it with a sledgehammer. This method is time-consuming and laborious, and the soil extractor will be damaged prematurely due to hammering. Contents of the invention [0005] The present invention aims at overcoming the above-mentioned defects...

[0003] When the rotary soil fetcher is fetching soil, due to the viscosity of the soil, the head is prone to blockage, so the soil fetching depth is limited each time, and the work efficiency is low

[0004] Most of the direct-pressure soil extractors are manually excavated. The conventional method is that one person holds the soil extractor and the other uses a sledgehammer to beat it. This method is time-consuming and laborious, and the soil extractor will be damaged prematurely due to hammering.
