Portable wild soil sampling device and sampling method thereof

Abstract

The invention discloses a portable wild soil sampling device and a sampling method thereof. The portable wild soil sampling device comprises a handle, a support rod, a scale disc, a regulating rod, round plates of at least one specification, a plug pin, sampling devices of at least one specification, soil containers of at least one specification and an ascending and descending assembly, wherein the lower end of the support rod is fixedly connected with a dial; the regulating rod and the round plate are movably connected under the dial; a plurality of rings of fixing grooves are formed at the lower end surface of the dial at the same diameter; the sampling device is detachably connected into a fixing groove of the dial; the soil container is detachably connected in the sampling device; theascending and descending assembly realizes the upward and downward reciprocating driving on the sampling device. Compared with the prior art, the device and the method have the beneficial effects thatthe depth and inner diameter regulation of the taken soil samples are completed; through the splicing of the soil containers and the sampling device, the disturbance and the damage on the soil samplecan be reduced; meanwhile, mechanical power is used for replacing the labor force; the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of soil samplers, and relates to a portable field soil sampler and a sampling method thereof. Background technique [0002] 1. The current sampler is used to lift the undisturbed soil of the lower layer of the test soil as a sample to understand its properties. The implementation methods of field operations are divided into manual push and external power push. The manual push is in the process of bulldozing, taking soil and obtaining soil samples. The consumption of manpower is large, and the implementation is difficult, which greatly increases the difficulty of the work of the sampler and affects its work efficiency. It is more feasible to push in with external power. [0003] 2. Once the existing sampler is made, the inner diameter and size of the sample are also fixed under the condition of sampling conditions and smooth sampling. However, the inner diameter and height of the sample required for different research...

Problems solved by technology

[0003] 2. Once the existing sampler is made, the inner diameter and size of the sample are also fixed under the condition of sampling conditions and smooth sampling. However, the inner diameter and height of the sample required for different researches are different, so directly The retrieved soil samples still need post-processing, which will have a certain impact on the post-sampling test operation

[0004] 3. The production part of the existing sampler is often relatively simple, the protection effect on the properties of the soil sample is weak, and the anti-disturbance performance is poor
