Drilling and sampling device for agricultural soil remediation

Abstract

The invention discloses a drilling and sampling device for agricultural soil remediation. The device comprises a lifting plate, wherein a driving motor is arranged in the middle of the top of the lifting plate, a drill rod is arranged on an output shaft of the driving motor, limiting rods are inserted into the four corners of the top of the lifting plate correspondingly, the same mounting plates are arranged at the bottoms of the four limiting rods, connecting springs are arranged at four corners of the bottom of the lifting plate correspondingly, and the bottoms of the four connecting springsare connected with the mounting plates through fastening bolts. The device is advantaged in that when the mounting plate is supported, a supporting rod and a base plate are prevented from sinking into the muddy ground, soil around the base plate can be used for pressing and fixing the base plate, when the lifting plate is pulled upwards, a connecting sleeve is stretched straight, soil and sewageon the connecting sleeve slide down, the sludge is prevented from being accumulated at the top of the base plate, the supporting rod is convenient to take out after sampling is completed, the sewage in the conveying pipe can be pumped into an extension pipe, and the situation that sampling precision of the soil is affected due to the fact that the sewage is doped in the soil during material takingis avoided.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a drilling sampling device for agricultural soil restoration. Background technique [0002] Soil remediation is a technical measure to restore the polluted soil to normal functions. With the continuous acceleration of the industrialization process, the unreasonable mining of mineral resources and their smelting discharge, long-term sewage irrigation and sludge application to the soil, and atmospheric pollution caused by human activities Subsidence, the application of chemical fertilizers and pesticides have caused serious soil pollution. The pollution of farmland soil directly causes the farmland to be unable to cultivate crops and reduces farmers' income. In the process of agricultural soil restoration, it is necessary to sample and analyze the soil in the farmland. According to the soil Carry out targeted remediation operations for the pollution situation. Since farmla...
