A soil sampling device for agricultural environmental protection testing with smashing function

Abstract

The invention discloses a soil sampling device for agricultural environmental protection testing with a smashing function, which includes a smashing box, a discharge box, an electric telescopic rod, a first servo motor and a second servo motor, and the top of the side wall of the smashing box is welded A discharge box is fixed, a contact plate is welded and fixed on the bottom movable plate, and the side of the contact plate is attached to the bottom of the vertical column, and the vertical column runs through the stabilizing cylinder, and the top of the vertical column is welded and fixed with a striking plate, and the striking plate is fixed on the top of the vertical column. The lower end surface of the playing plate is welded and fixed to the top of the return spring, and the bottom of the return spring is welded and fixed to the top of the stabilizing cylinder. The soil sampling device for agricultural environmental protection testing with smashing function adopts a new structural design, which enables the device to conveniently separate and take out the compact columnar soil samples in the drill pipe disassembled from the soil drilling rig, simplifying labor operation, reduce manpower consumption, and avoid damage to the drill pipe, and at the same time, it can crush the separated columnar soil samples, which is convenient for sampling and transfer.

Description

technical field [0001] The invention relates to the technical field of agricultural environmental protection detection equipment, in particular to a soil sampling device for agricultural environmental protection detection with a crushing function. Background technique [0002] Agricultural environmental protection testing is an important technical means of agricultural environmental management. Through agricultural environmental protection testing, it can timely, accurately and comprehensively reflect the quality of agricultural environment and its changing rules and development trends, and track the residues and concentrations of pollutants in agricultural, livestock, and aquatic products. Accumulate dynamics to ensure the safety of agricultural products and human health, and provide a scientific basis for agricultural environmental management. Among them, sampling and testing the soil of the land where agricultural production activities are located is an important part of a...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a soil sampling device for agricultural environmental protection testing with a crushing function, so as to solve the above-mentioned background technology that workers use wrench steel pipes to knock and vibrate, so that the columnar soil is separated from the inner wall of the drill pipe, and the operation is cumbersome and laborious. In addition, the drill pipe is deformed, the columnar soil is relatively compact, and it is difficult to separate the columnar soil for sampling, and the overall weight is heavy, which is not easy to transfer.
