Description

a soil sampler

technical field

The utility model belongs to the technical field of soil sampling devices, and more specifically relates to a novel soil sampling device.

Background technique

Soil is the cornerstone of the survival and development of human society, and an important material basis for ensuring the safety of human food and the ecological environment and the sustainable development of the economy and society. Therefore, protecting the soil environment is an important part of promoting the construction of ecological civilization and maintaining national ecological security. In recent years, the field of soil science research and geological prospecting has been widely concerned by the ecological environment protectors. However, along with the development of human society and economy, it also brings a series of major challenges such as resource shortage, energy shortage, environmental pollution and climate change. At present, the overall situation of my country's soil environment is worrying, and some areas are seriously polluted. Therefore, it is very important to strengthen soil scientific research and take appropriate measures for pollution prevention and control in time to ensure the safety of the ecological environment.

The collection of soil samples is the basic work in the field of soil science research and geological exploration. It provides a material basis for the determination of the physical and chemical properties of soil samples. It is time-consuming and labor-intensive to use excavation methods for soil sampling, which is not economical and causes great damage to the environment, especially in deep layers. Soil sampling can be extremely difficult. At the same time, the traditional sampling tools are manually pressed the sampler directly into the soil layer for sampling. It is difficult to realize the sampling operation when facing some dry and hard soil layers. It is neither labor-saving nor timely control of the excavation depth. .

For example, the application with Chinese patent application number 201510430563.9 discloses a quick soil collection device. The collection device of this application includes a straight soil-taking rod for collecting soil. The lower end of the soil-taking rod has a storage section. The storage section surrounds and forms a slot for collecting soil, and the slot is arranged along the axial extension of the storage section and runs through the lower end of the storage section. This application optimizes the structure of the storage section at the front end of the earth-taking rod, which can effectively avoid the phenomenon of test soil falling off during the soil collection process to a certain extent and improve the efficiency of soil collection. However, the device used in this application When taking soil sampling, it is necessary to directly drive the soil-taking rod to rotate 360° by turning the handle, which is time-consuming and laborious. When the soil to be collected is relatively hard, it is difficult to insert it into the sampling depth.

In order to improve sampling efficiency, some new soil samplers are currently driven by motors, hydraulic components and other equipment. Although the sampling efficiency has been improved, it is difficult to meet the basic conditions of electric power and hydraulic oil supply for soil sampling in the field. . For example, the Chinese patent application No. 201520630767.2 discloses a soil sample single-time multi-layer collector. The application drives the driving gear through the motor, so that the driven gear that rotates together drives the nut to rotate, and the screw drives the sampling tube. Rotate and turn into the soil to insert the sampling tube into the soil; when the sampling tube is almost completely in the soil, reverse the motor to unscrew the sampling tube with the soil sample. This application realizes fully mechanized sampling, is easy to operate, and can be used smoothly in geologically hard soil, but it is difficult to meet the demand for motor power supply when soil sampling is carried out in the field, and it is difficult to really promote its use.
