Soil sampling device

Abstract

The invention relates to the technical field of soil sampling devices and discloses a soil sampling device. The soil sampling device comprises a base and a supporting rod, wherein a pulley is arranged at the upper end of the supporting rod, a winding roller is arranged at the middle part of the supporting rod, a sling is arranged on the winding roller, a vibrator comprises a vibrator shell, a left end cover is arranged at the left end of the vibrator shell, a right end cover is arranged at the right end of the vibrator shell, an eccentric rotating block is arranged between the left end cover and the right end cover, the two ends of the eccentric rotating block are respectively connected with the vibrator shell by virtue of a bearing, and the right end of the eccentric rotating block is connected with a gasoline engine by virtue of a torque transmission flexible shaft; and the upper end of the vibrator shell is connected with the sling by virtue of a lifting ring, the center of the lower end of the vibrator shell extends downward to form a connecting base, a drill rod joint is arranged on the connecting base, the lower end of the drill rod joint is connected with a hollow drill rod, a drill bit is arranged at the lower end of the drill rod, and a drill rod guide sleeve is arranged on the base. The soil sampling device disclosed by the invention has the beneficial effects that labor is saved and convenience is realized in application and soil sampling efficiency is high.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a soil sampling device. Background technique [0002] The collection of soil profile samples is the basis for soil system classification investigation, soil configuration analysis, soil fertility characteristics research, soil nutrient migration and soil ecological investigation. Traditional methods generally use digging and soil drilling methods to collect soil samples. Although excavating soil profile pits can obtain undisturbed soil samples at different depths, the workload is heavy, the efficiency is low, and the environmental damage to the sampling site is greatly damaged; the soil drilling method is that the operator manually rotates the drill pipe into the soil layer. The resistance to the drill pipe is relatively large. The operator needs to hit the drill pipe with a hammer to generate a large downward force, so that the soil drill can enter the deep soil layer. Thi...
