Description

Earth sampling device for geological engineering

Technical Field

The utility model provides a soil sampling device for geological engineering, and belongs to the technical field of coal mine exploration.

Background

Mineral exploration is geological work performed by applying effective means and methods to mineral deposits which are determined to have industrial value through general survey and detail survey and providing necessary mineral reserves and geological technical and economic data for mine construction design. Also known as deposit exploration. The deposit exploration mainly provides basic data and basis for the aspects of mine construction design, determination of mine construction scale, product scheme, mining mode, development scheme, selection of mining method, ore dressing (metallurgy) or processing technical method, overall mine construction arrangement, perspective planning, economic and social benefits of future mine enterprises and the like. In the process of surveying coal mine geology, not only the terrain of a coal mine region needs to be known, but also the soil quality of the coal mine region and the components of a coal mine contained in the soil need to be researched, when the detection research is carried out on the soil quality of the coal mine region and the components of the coal mine contained in the soil, sandy soil of the coal mine region needs to be collected firstly, at present, when sandy soil sampling work is carried out, a worker needs to open a hole on the ground by using a drilling device firstly, the soil containing broken ores is collected by using a sampling device after the hole is opened to a rock layer on the ground, the ground opening and the sampling work need to be carried out separately, which is troublesome, not only brings inconvenience to the worker, but also reduces the efficiency of the sampling work, and most of the traditional sampling devices adopt an exposed sampling box, and because the soil has certain viscosity, the soil is easy to be pulled by the soil outside the collected soil block in the process of pulling out the sampling box, thereby causing falling off and affecting the sampling effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a soil sampling device for geological engineering, which can overcome the defects, can conveniently sample and can ensure that collected soil cannot fall off.

In order to solve the problems, the utility model provides a soil sampling device for geological engineering, which comprises a top plate and a base, wherein a screw rod is arranged between the top plate and the base, a sliding block is sleeved on the screw rod, the screw rod is rotationally connected between the top plate and the base, and a motor for driving the screw rod to rotate is arranged on the top plate; the sliding block is fixed on the wall of the driving box of the drill rod; the drilling rod driving box is internally provided with a driving motor, the lower end of the driving motor is provided with a bearing seat, a rotating shaft penetrates through the inside of the bearing seat, the lower end of the rotating shaft is provided with a drilling rod, and a sampling tube is arranged in the drilling rod.

Preferably, be equipped with a plurality of sample chamber in the sampling tube, be equipped with circular sample gate on every sample chamber.

Preferably, the sampling door is controlled by a motor to rotate to open and close the sampling cavity.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model improves the efficiency of soil sampling, and ensures that the soil is not polluted and is not pulled to fall off after sampling.
