Soil sampling device

Abstract

The invention discloses a soil sampling device which comprises a bottom plate, two main plates are fixedly arranged on the surface of the top of the bottom plate, a partition plate is arranged between the two main plates, and a sliding plate and a driving plate are arranged between the partition plate and the two main plates respectively. Driving grooves are formed in the two sides of the driving plate and are formed in the inner walls of the partition plate and the main plates, driving blocks are arranged at the two ends of the driving plate and are arranged in the driving grooves, and a sampling rod is arranged at the bottom of the sliding plate. Through arrangement of the sliding plate and a sampling rod, a hydraulic lifting rod pushes the sliding plate to move downwards, a second motor works to drive a storage rod to rotate, and a rotating block and a baffle at the bottom of the rotating block also rotate along with the storage rod so that two through holes are communicated, and soil on the outer side of the sampling rod enters the storage rod to store samples; after sampling is completed, the second motor works again to seal the through holes, and sampled soil can be sealed underground to avoid damage to soil properties.

Description

technical field [0001] The present invention relates to the field of geological exploration, and more particularly, the present invention relates to a soil sampling device. Background technique [0002] Soil sampling is an important part of soil information acquisition technology. In order to determine the adequacy of soil nutrients in the whole area, it is necessary to correctly take soil samples and conduct testing and analysis. Generally, statistical methods are used to analyze the statistics of sample test values, so as to estimate the entire area. Before sampling, the section should be refurbished and cleaned, and the topmost layer of floating soil should be cut off, and then the samples should be taken from the top to the bottom layer by layer from the typical part of the center. Most of the existing soil sampling equipment adopts Luoyang shovel, and the handle of the Luoyang shovel is generally long and fixed. It cannot be adjusted according to the needs of use in the...

AI Technical Summary

Problems solved by technology

Most of the existing soil sampling equipment uses Luoyang shovel, and the handle of Luoyang shovel is generally long and fixed, which cannot be adjusted according to the use requirements during use, and sometimes the surface of the soil to be sampled is hard and difficult to dig Sampling is difficult, and in many specific environments, the soil will react with the air after it is taken out, and the subsequent data will be inaccurate. Therefore, it is necessary to invent a soil sampling device.
