Problems solved by technology

[0004] Regardless of the above-mentioned samplers, there are the following deficiencies: 1. When sampling, it is necessary to manually ensure the verticality of the insertion. The manual error is large, resulting in large deviations in verticality, and the natural state of the soil layer cannot be maintained; 2. It cannot be accurately controlled. Sampling depth, there are situations where too much force is inserted too deep, resulting in inaccurate sampling

Abstract

The invention discloses a soil sampling device, and relates to the technical field of environment-friendly soil sampling. The soil sampling device comprises an operating hand rod and a sampling cylinder at the front end of the operating hand rod, wherein an adjusting connector is connected between the operating hand rod and the sampling cylinder, a fixed convex ring is arranged at the end portionof the front end of the operating hand rod, and is connected with a contact ring in contact with the bottom surface through at least three connecting rod structures, a cavity is formed in the end faceof the front end of the operation hand rod, a guide column is arranged in the cavity, the adjusting connector is of a columnar structure capable of sliding up and down along the cavity, a guide groove in guide fit with the guide column is formed in the upper surface of the adjusting connector, a locking part is arranged on the bottom side face of the fixed convex ring, a locking mechanism is arranged on the locking part, and a groove channel matched with the locking mechanism is formed in the side face of the periphery of the adjusting connector. Through combined application of the sampling cylinder, the connecting rod structure and the contact ring, surface-layer soil of wet soft soil can be accurately sampled according to requirements.

Description

technical field [0001] The invention belongs to the technical field of environmental protection soil sampling, in particular to a soil sampling device. Background technique [0002] Soil sampling is one of the important basic tasks in the scientific and technological work of soil and ecological research, and the soil sampler is a special tool for soil sampling in soil testing, formula fertilization, soil monitoring, and cultivated land fertility survey and quality evaluation projects. [0003] At present, the common samplers on the market mainly include T-shaped samplers for hard soil sampling and in-line samplers for soft soil sampling; when the T-shaped sampler is used, the sampler needs to be straight down, and both hands Hold the handle and rotate back and forth while pressing down. In order to maintain the natural state of the soil, the downward pressure should be uniform, and the force should depend on the shear strength of the soil; Generally 150-200cm), insert it st...
