Supporting underframe of soil collecting component

Abstract

The invention relates to the technical field of soil detection, and discloses a supporting underframe of a soil collecting component, the supporting underframe comprises a shovel handle, the bottom end of the shovel handle is fixedly connected with a shovel head, the outer side of the top end of the shovel handle is movably sleeved with a horizontal disc, the outer side of the top end of the horizontal disc is provided with a vertical movable cylinder, and the horizontal disc is sleeved with a self-adjusting column through the movable cylinder; a reset spring is fixedly installed on the outer side of the self-adjusting column, a follow-up disc is movably connected to the bottom end of the horizontal disc, follow-up threads are arranged on the outer surface of the middle of the shovel handle, an inflation cock is fixedly installed on the outer side of the follow-up disc, and a balance cavity is formed in the side face of the horizontal disc. According to the invention, the extension bracket and the adjusting cylinder are arranged, and air pressure in the adjusting cylinder is utilized to control the extension length of the four chassis supporting legs, so that the supporting chassis of the soil collecting part can be randomly mounted on an uneven ground for use and use, and the problem that sampling randomness is influenced due to the fact that sampling points are limited by terrains is avoided.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a support chassis of a soil collection component. Background technique [0002] The collection of soil samples is the basic work in the field of soil science research and geological exploration, which provides a material basis for the determination of the physical and chemical properties of soil samples. Changes in moisture and nutrients in agricultural soil have an important impact on crop yields. In recent years, with the extensive use of chemical fertilizers, the water and nutrient structure in the soil have undergone significant changes. Therefore, it is of great significance to explore the soil to study the water, nutrient content and its changing law in the soil to ensure the production of crops. [0003] The soil collector is one of the necessary tools for soil research. At present, the domestic soil collector is simple in structure, and the deep soil is sampled ve...
