Sampling device for soil improvement

Abstract

The invention discloses a sampling device for soil improvement, which comprises a drill bit and a sampling column, wherein a plurality of propelling cavities are formed in the sampling column, a propelling air bag is arranged on the inner wall of one side of each propelling cavity, an inflation pipe is arranged above each propelling air bag, the propelling air bags are connected with one another through the inflation pipes, an inflation pump is arranged at the top of the inflation pipe at the uppermost end, the inflation pump is fixedly connected to the outer wall of the top of the sampling column, a sampling cylinder is arranged on one side of each propelling air bag, a smashing rotating shaft is rotatably connected to the inner wall of each sampling cylinder, a plurality of mounting grooves are formed in the outer wall of each smashing rotating shaft at equal intervals, pentagonal cutters are connected to the inner walls of the mounting grooves in a sliding mode, a plurality of third springs are arranged between the pentagonal cutters and the mounting grooves, and a plurality of arc-shaped smashing cutters are arranged between every two pentagonal cutters. Sampled soil can be smashed, and then the situation that the soil is bonded together, and consequently the soil cannot enter the sampling cylinder or cannot be discharged from the sampling cylinder is avoided.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a sampling device for soil improvement. Background technique [0002] Soil improvement refers to the use of soil science, biology, ecology and other multidisciplinary theories and technologies to eliminate or prevent unfavorable factors that affect crop growth and cause soil degradation, improve soil properties, increase soil fertility, and create a good soil environment for crops A collective term for a series of technical measures of conditions. [0003] Before improving the soil, it is necessary to take a sample of the soil, and then analyze the ratio of each element contained in the soil through experiments, so as to determine the technical solution for soil improvement according to the test data; at present, the sampling device is used for sampling, but the soil Because it is not fertile and has not been cultivated for a long time and lacks organic matter, the soil...

[0003] Before improving the soil, it is necessary to take a sample of the soil, and then analyze the ratio of each element contained in the soil through experiments, so as to determine the technical solution for soil improvement based on the test data; currently sampling is performed using a sampling device, but the soil Because it is not fertile and has not been cultivated for a long time and lacks organic matter, the soil will compact and harden the soil, which will cause the soil sample to fail to enter the sampling cylinder when the sampling device samples the soil at different depths, which will cause serious damage to the sampling work of the staff. great difficulty
