Embodiment 1

[0037] Example 1, such as Figure 1-9 As shown, the present invention provides a sampling device and an operating method that can avoid sample sticking and clogging in geological exploration, including a base 1, two screw mandrels 2 are installed on the upper end of the base 1, and the circular arc surfaces of the two screw mandrels 2 are threadedly connected with Drilling machine 3, control switch 6 is installed on the surface of drilling machine 3, sampling tube 4 is installed on the lower end of drilling machine 3, the surface of drilling machine 3 is provided with percussion structure 5, and the side of drilling machine 3 near control switch 6 is provided with protective structure 7.

[0038] Let's talk about the specific setting and effect of its knocking structure 5, protective structure 7 and method of operation in detail below.

[0039] Such as image 3 and Figure 4 As shown, the knocking structure 5 includes a mounting plate 501, the mounting plate 501 is fixedly c...

Embodiment 2

[0050] Embodiment 2, on the basis of embodiment 1, this operation method step is:

[0051] S1. First check whether the equipment is normal, then place the base 1 at the location to be tested and fix it;

[0052] S2, start the drilling rig 3, so that the drilling rig 3 drives the sampling pipe 4 to perform drilling and sampling at the site to be measured;

[0053] S3, after the sampling is finished, use the screw mandrel 2 to move the drilling machine 3 upwards, and the sampling pipe 4 slides out from the soil to be tested;

[0054] S4. Hook the hook plate 512 on the sampling tube 4, and make the rubber pad 513 contact the surface of the sampling tube 4;

[0055] S5, start the motor 507, the motor 507 drives the adjustment wheel 508 to rotate, the adjustment wheel 508 continuously pushes the ejector rod 505, the ejector rod 505 drives the slide bar 502 to move, the slide bar 502 still knocks the sampling tube 4 continuously, and reaches the sample in the sampling tube 4 , to ...

Abstract

The invention provides a sampling device capable of avoiding sticking and blocking of samples in geological exploration and an operation method, and relates to the technical field of geological exploration drills, the sampling device comprises a base, two screw rods are mounted at the upper end of the base, the arc surfaces of the two screw rods are in threaded connection with a drilling machine, and a control switch is mounted on the surface of the drilling machine; a sampling pipe is mounted at the lower end of the drilling machine, a knocking structure is arranged on the surface of the drilling machine and comprises a mounting plate, the mounting plate is fixedly connected to the surface of the drilling machine through bolts, a sliding rod is slidably inserted into the surface of the mounting plate, one end of the sliding rod is fixedly connected with a circular plate, and the arc surface of the sliding rod is sleeved with a spring A; and the two ends of the spring A are fixedly connected with the circular plate and the sliding rod correspondingly. According to the invention, the problem that a sampling pipe of a traditional drilling machine is easily affected by soil and blocked, so that an operator is difficult to take out a sample from the sampling pipe is solved.

Description

technical field [0001] The invention relates to the technical field of geological exploration drilling rigs, in particular to a sampling device and an operating method capable of avoiding sample sticking and clogging in geological exploration. Background technique [0002] Drilling rigs are mainly used for geological exploration, including coal fields, petroleum, metallurgy, minerals, geology, hydrology, non-ferrous metals, and nuclear industry exploration. By using drilling rigs to obtain geological soil samples for testing, it provides reference data for subsequent construction. [0003] After using the drilling rig to sample the geological exploration position, it is necessary to take out the soil sample in the sampling tube of the drilling rig. When the sample needs to be taken out after the drilling rig is finished, the sampling tube of the traditional drilling rig is prone to blockage due to the influence of the soil, resulting in It is difficult for the operator to re...
