Sampling device for spirally propelling soil

Abstract

The invention discloses a sampling device for spirally propelling soil, and relates to the field of soil collection equipment. The sampling device comprises a fixed base, an L-shaped supporting rod, asupporting table, a connecting rod and a drill bit, wherein first hinges are arranged at the three corners above the fixed base, the L-shaped supporting rod comprises an upper supporting rod, a lowersupporting rod and a first hinged seat, a sliding groove is formed in the upper surface of the upper supporting rod, the first hinged seat is hinged to the first hinge, only second hinges are arranged at the three corners of a regular triangle plate body, a second hinged seat is arranged at one end of the connecting rod, the second hinged seat is hinged with the second hinge, a limiting plate ishinged to the other end of the connecting rod, and the limiting plate is clamped in the sliding groove. According to the invention, through sliding fit between the L-shaped supporting rod and the connecting rod, the rocker is continuously rotated to enable the drill bit fixed in the supporting table to be continuously and vertically pushed into soil along with rotation of the rocker so as to conveniently and smooth perform outdoor soil collection work, and errors are not prone to occurring in vertically-downward collected soil so as to improve the outdoor working efficiency.

Description

technical field [0001] The invention belongs to the field of soil collection equipment, in particular to a screw-propelled soil sampling device. Background technique [0002] With the continuous acceleration of urbanization and industrialization and the frequent interference of human activities, the problem of soil pollution has become more and more serious. On April 17, 2014, the Ministry of Environmental Protection and the Ministry of Land and Resources jointly issued the "National Soil Pollution Survey Bulletin". The heavily polluted sites are 11.2%, 2.3%, 1.5% and 1.1%, respectively. The overall soil environment is not optimistic, and pollution control is imminent. [0003] Clarifying the composition and concentration of soil pollutants is the basic premise for formulating soil pollution control measures, and soil sample collection and analysis are the basic means to obtain soil physical, chemical, biological properties and composition characteristics. The soil sampler...

Problems solved by technology

[0006] The object of the present invention is to provide a sampling device for screw-propelled soil. Through the sliding fit between the L-shaped strut and the connecting rod, the drill bit fixed in the support table can be continuously pushed vertically into the soil as the rocker rotates, solving the problem of The existing soil sampling is prone to errors and the problems of low field work efficiency
