Problems solved by technology

At present, the commonly used sampling device is the clam sampler. The main feature and main problem of this sampler is that it relies on man-made and the weight of the sampling device to make it fall into the sediment. This sampling method will make it difficult to control the sampling depth, and there is a certain blindness The pipe wall of the sampler is realized by the traction of the rope and the weight of the sampler itself. This opening and closing method is often not effective, causing the sample to fall back during the lifting process, which cannot meet people's needs.

Abstract

The invention discloses a drilling sampling device and a use method and relates to the technical field of drilling sampling equipment. An operation handle (5) is arranged on a lifting shaft (4), a motor (6) is arranged at one side of a lifting device (3), a control device (7) is arranged between the lifting device (3) and the motor (6), a speed regulating rotary knob (8) and a power switch (9) are arranged on the control device (7), the upper end of a main shaft (11) is connected with the motor (6) through a connecting sleeve (10), the lower end of the main shaft (11) is connected with a sampling cylinder (12), the upper end of the sampling cylinder (12) is provided with a cover body (13), and a plurality of triangular edge boards (14) are evenly arranged at the bottom of the sampling cylinder (12). The drilling sampling device is reasonable in structural design, easy to operate, convenient to use, high in operation efficiency, large in sampling range, light, low in labor intensity, convenient to carry, safe, reliable and capable of automatically controlling the sampling depth, being automatically controlled to be switched on and switched off and satisfying the use requirements of people.

Description

Technical field: [0001] The invention relates to the technical field of drilling sampling equipment, in particular to a drilling sampling device and a use method. Background technique: [0002] Drilling refers to the use of instruments to drill holes underground to explore mineral deposits, stratum structures, soil properties, etc., and to take out soil or cores for analysis and research. [0003] Drilling is an engineering construction project that uses drilling rig equipment to drill holes from the surface to the ground to achieve the desired task. From the purpose of drilling, it can be divided into: geological drilling, hydrological water well drilling, engineering exploration drilling, oil drilling and so on. Among them, geological drilling: the operation of obtaining cores and ore samples from different depths in the borehole for analysis and research, identifying ore bodies or dividing strata, and determining the geological conditions of strata. Usually, the cost of ...
