Soil sample sampling equipment based on combined-type soil sample horizontal cutting apparatus

Abstract

The present invention discloses soil sample sampling equipment based on a combined-type soil sample horizontal cutting apparatus, the soil sample sampling equipment includes two stand columns, an upper beam, an electric rotating seat, an electric lower press head, a soil sampling cutter located just below the electric lower press head, a lower press plate installed on the upper part of the soil sampling cutter and the combined-type soil sample horizontal cutting apparatus arranged on the outer side of the soil sampling cutter, the soil sampling cutter comprises an annular cutter and a cylindrical protection tube, a control box is arranged on the stand columns, the combined-type soil sample horizontal cutting apparatus comprises a lower position limitation ring, a plurality of side pushing panels and an upper pressure ring; the lower position limitation ring is a round ring with a cutting steel wire winding around the outer wall of one side, and the bottom of the lower position limitation ring is provided with a cutter edge, the outer side wall of the bottom of the lower position limitation ring is provided with two horizontal rings, two ends of the cutting steel wire respectively pass through the two horizontal rings, the side pushing panels are fixed on the upper pressure ring by a vertical connecting plate. The soil sample sampling equipment is simple in structure, reasonable in design, easy in use and operation, and good in use effect, and can simply and rapidly complete a sampling procedure, and the sampling effect is good.

Description

technical field [0001] The invention belongs to the technical field of soil sampling, in particular to a soil sample sampling device based on a combined soil sample horizontal cutting device. Background technique [0002] The soil fetcher is used to lift the undisturbed soil of the lower layer of the test soil as a sample to understand its properties. When sampling the undisturbed soft soil sample, a thin-walled soil fetcher is usually used to obtain the soil. During the soil collection process, in order to make the soft soil weak structure The skeleton is well preserved and less damaged, so the process of soil extraction needs to be very careful, minimizing or even avoiding the disturbance of soil samples from factors such as soil extraction tools and soil extraction methods. The diameter of the soil fetcher should not be less than Φ120mm. For sandy soil, a soil fetcher with a smaller diameter can be used to prevent the soil sample from falling off during extraction. In th...

Problems solved by technology

In the actual sampling process, in order to understand the address status of a certain stratum, it is often necessary to take soil vertically downward. Sampling failure due to soil sample falling off, disturbance caused by the separation of the bottom of the soil sample collected in the earth taker from the underlying stratum, etc.

In addition, existing soil extractors also have defects such as inconvenient use and operation, poor use effect, etc.

Therefore, there is a lack of a soil sample sampling device based on a combined soil sample horizontal cutting device that is simple in structure, reasonable in design, easy to use, and has a good effect. It can easily and quickly complete the sampling process, and the sampling effect is good. After vertically entering the formation, the bottom of the collected soil sample can be cut to separate the soil sample from the original soil layer, thereby greatly improving the sampling quality, reducing or even avoiding the disturbance caused by the separation from the original soil layer, and Can effectively reduce the probability of soil sample falling off
