Soil sampling device of saline-alkali soil pollution remediation equipment and drilling method of soil sampling device

Abstract

The invention discloses a soil sampling device of saline-alkali soil pollution remediation equipment and a drilling method of the soil sampling device, and relates to the technical field of environment-friendly machinery. The invention aims to solve the problems that a soil sample needs to be knocked by a tool when being separated from a sampling barrel, the soil sample is not easy to separate, and the soil sample is easy to crush and mix. The device specifically comprises a rack, a pulling plug is fixedly installed at the end of the rack, a power supply mechanism is fixedly installed on one side of the interior of the rack, a collecting shell is fixedly installed at the other end of the interior of the rack, and a negative pressure fan electrically connected with the power supply mechanism is fixedly installed at the top end of the collecting shell. According to the soil sampling device, soil is sucked into the collecting shell through an oval suction hole, a drilling pipe and a suction pipe, multiple soil samples can be collected by moving an auxiliary soil sampling mechanism, after the drilling pipe is screwed into a soil layer to reach the set depth, the driving motor rotates reversely, a soil sampling structure in the main soil sampling mechanism pops up, and the sampling operation of soil samples of different depths is completed; and multiple samples of different soil layers can be obtained through the two soil sampling modes.

Description

technical field [0001] The invention relates to the technical field of environmental protection machinery, in particular to a soil-taking device and a drilling method for saline-alkali land soil pollution restoration equipment. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops, and the formation of alkaline soil and alkalized soil is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is common Higher, severe saline-alkali soil areas where plants can hardly survive, the main feature of saline-alkali soil is that it contains more water-soluble salt or alkaline substances. Due to the high salinity and high alkalinity, the soil humus is leached and the soil structure is damaged. It is sticky when wet and hard when dry. There are often white salt deposits on the soil surface, poor ventilation and water permeability. [0003] Al...

Problems solved by technology

[0003] All kinds of saline-alkali soils are formed under certain natural conditions, and the essence of their formation is mainly the redistribution of various soluble salts in the horizontal and vertical directions on the ground, so that the salt gradually accumulates on the soil surface in the salt-gathering area. Accumulated, therefore, with the increase of the depth of the soil layer, the saline-alkali land has different salinity in the soil, and the means of restoration will change. Therefore, it is necessary to frequently take soil samples for analysis during the restoration process. Saline-alkali land is hard when it is dry. At present, it mainly depends on the rotation of the sampling cylinder to enter the bottom of the soil layer, and the columnar soil is taken out to sample it section by section. When the soil sample is separated from the sampling cylinder, it needs to be knocked with tools. It is easy to cause soil samples to be broken and mixed, which will affect the results of soil sample analysis
