Automatic feed type soil sampling device

Abstract

The invention relates to the technical field of soil sampling devices, and discloses an automatic feed type soil sampling device. The automatic feed type soil sampling device comprises a base and a support bar, wherein a pulley is arranged at the upper end of the support bar, a wind-up roll is arranged in the middle position of the support bar, a suspension cable is arranged on the wind-up roll, the upper end of the suspension cable bypasses the pulley and is connected with a vibrator, two bearings are arranged on both the left and right ends in the shell of the vibrator, an eccentric turning block is arranged between the two bearings, the two ends of the eccentric turning block are in rotating connection between the bearings, a connecting column is arranged at the right end of the eccentric turning block, the connecting column is connected with a gasoline engine through a torque transmission flexible shaft, the center of the lower end of the shell of the vibrator extends downward to form a lower connecting base, a drill rod joint is arranged on the lower 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, a rigid plastic bushing is arranged in the drill rod, and a drill rod guide sleeve is arranged on the base. The automatic feed type soil sampling device has the beneficial effects of no need of manual driving, labor-saving and convenient use, and high efficiency in soil sampling.

Description

technical field [0001] The invention relates to the technical field of soil sampling devices, in particular to an automatic feeding 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 ent...
