Sealed soil collection equipment capable of automatically adjusting collection depth for agricultural research

Abstract

The invention relates to soil collection equipment, in particular to sealed soil collection equipment capable of automatically adjusting collection depth for agricultural research. The sealed soil collection equipment comprises a collection cylinder, a drill bit is arranged below the collection cylinder and used for drilling soil, a collection groove is formed in the collection cylinder and eccentrically formed in the collection cylinder, a sealing groove is formed below the collection cylinder, a sealing disc is arranged in the sealing groove and rotationally connected into the sealing groove, a round hole is formed in the sealing disc, and the size of the round hole is matched with the size of the collection groove. Soil at the specified depth is collected through the arranged collecting cylinder, and after collection is completed, the telescopic rod retracts, so that the round hole and an inlet of the collecting groove are staggered, sealing of the inlet is completed, mutual interference of soil at different depths is avoided, and therefore the research precision is improved, and the agricultural research structure precision is improved.

Description

technical field [0001] The invention relates to a soil collection device, in particular to a sealed soil collection device for automatic adjustment of collection depth for agricultural research. Background technique [0002] In agricultural research, due to different research purposes, there are different requirements for the collection of soil samples. To study the relationship between soil moisture and crop yield, it is required to collect soil samples at a depth of 2 to 3 meters in each growth period, but the existing collection equipment often brings out the surface soil when collecting, and it is located in the same device as the soil to be tested At this time, direct contact of soils at different depths will cause water dispersion, which will affect the research results. The purpose of the present invention is to seal the sampling soil at a specific depth in the agricultural research process, so as to avoid soils at different depths from interfering with each other, th...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a kind of sealed soil collection equipment that automatically adjusts the depth of collection for agricultural research, to solve the problem that the existing collection equipment proposed in the above background technology often takes out the surface soil when collecting, which is different from the soil to be detected. The soil is located in the same device. At this time, the direct contact of the soil at different depths will cause water dispersion, which will affect the research results.
