Deep soil sampler for environmental monitoring

Abstract

The invention discloses a deep soil sampler for environmental monitoring. The deep soil sampler comprises a collecting device and a transmission device, wherein the collecting device comprises a hollow drill rod, a working box and a collecting pipe; the hollow drill rod is arranged inside the working box; the collecting pipe is arranged inside the hollow drill rod; a collecting groove is arrangedinside the collecting pipe; one end of the hollow drill rod is connected with a drill bit by the bolt; the other end of the hollow drill rod is provided with a cutter tooth; the cutter tooth is connected with the collecting pipe; a collecting box is arranged at a lower part of the working box; a soil sampling plate is arranged at the bottom of the collecting box; a pulley is arranged under the soil sampling plate; a part of the collecting box near the hollow drill rod is hollowed and suspended; the transmission device comprises a motor, a linkage shaft, a transmission shaft and a drill bit sleeve; the motor is connected with the transmission shaft by the linkage shaft; the transmission shaft is connected with the drill bit sleeve. The deep soil sampler provided by the invention effectivelycontrols the depth of the collected soil, is also easy in collection on hard soil, relatively low in time consumption, and higher in efficiency, and is simple in structure, convenient to use, and portable.

Description

technical field [0001] The invention relates to the field of soil sampling for environmental monitoring, in particular to a deep soil fetcher for environmental monitoring. Background technique [0002] Soil environment monitoring refers to the determination of environmental quality and its changing trend through the determination of representative values ​​of factors affecting soil environmental quality. Soil environmental testing generally includes technical content such as spot sampling, sample preparation, analysis methods, result characterization, data statistics, and quality evaluation. Soil sampling is usually carried out with soil grabbers in soil environmental testing. The following disadvantages exist in the soil sampling process of traditional soil fetchers: first, the depth of soil sampling is limited; second, the traditional soil fetchers are greatly affected by the hardness of the soil during the sampling process; third, traditional soil fetchers are time-consu...
