Description

Technical Field

[0001] The utility model belongs to the technical field of geological surveying and mapping, and specifically relates to a geological surveying and mapping sampling device. Background Art

[0002] In geological surveying, it is necessary to sample the rocks or soil layers below the surface. The general sampling method is to use a geological surveying drill, which uses a drill barrel to select a certain depth underground. The rocks or soil collected inside the drill barrel can visually observe the changes in soil quality below the surface, facilitating subsequent analysis of rock material, chemical properties, etc.

[0003] When the drill barrel currently used on the drilling rig drills into the rock, due to its long length, when the rock samples collected inside are taken out, a hammer is generally used to generate vibration force to take out the rock. However, this method of taking out the rock is prone to cause problems such as rock sample breakage and fracture, and the taking out speed is slow. During long-term use, the drill barrel is subjected to the hammer's striking force and is prone to deformation, which reduces its service life. Utility Model Content

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0024] like Figure 1-Figure 7 As shown, a geological surveying and sampling device comprises a drill barrel 1, a transfer tube 2 is arranged at the bottom of the drill barrel 1, a plurality of blades 3 are fixedly connected to the bottom end face of the transfer tube 2, the transfer tube 2 and the drill barrel 1 are threadedly connected, the top end face of the transfer tube 2 and the bottom end face of the drill barrel 1 are both stepped, after the drill barrel 1 and the transfer tube 2 are docked, the outer wall diameters of the two are the same, which is convenient for movement in the borehole, a sealing ring 4 is fixedly connected to the top end face of the transfer tube 2, a sealing groove 5 is opened on the bottom end face of the drill barrel 1, the sealing ring 4 is adapted to the sealing groove 5, a push ring 6 is arranged near the top of the inner cavity of the drill barrel 1, and a control component is arranged on the side wall of the push ring 6.

[0025] like Figure 6 and Figure 7 As shown, the control component includes a slider 7 fixedly connected to the side wall of the push ring 6, a slide groove 8 is provided on the inner wall of the drill tube 1, the slider 7 is slidably connected to the slide groove 8, a steel wire 9 is fixedly connected to the bottom surface of the slider 7, the other end of the steel wire 9 passes through the bottom end surface of the drill tube 1 and is fixedly connected to a pull ring 10, the steel wire 9 is movably connected to the drill tube 1, and a reset component is arranged on the upper side of the slider 7.

[0026] A receiving groove is provided on the bottom end surface of the drill tube 1, and the pull ring 10 is located in the receiving groove.

[0027] Among them, the steel wire 9 is used as the force-bearing structure, which has the characteristics of small diameter, high strength, and not easy to break. When used in this solution, it can also withstand the friction and corrosion of rocks and groundwater, ensure good flexibility and reliability when subjected to force, and improve its performance.

[0028] like Figure 2 and Figure 6 As shown, the reset assembly includes a cavity 11 opened on the inner side of the drill tube 1, the cavity 11 is located on the upper side of the slide groove 8, a groove wheel 12 is rotatably connected in the cavity 11, a spring 13 is installed on the side wall of the groove wheel 12, an elastic rope 14 is wound around the groove wheel 12, one end of the elastic rope 14 extends into the slide groove 8 and is fixedly connected to the slider 7.

[0029] Specifically, the running length of the mainspring 13 can be selected according to actual needs. Since the elastic rope 14 is used as the connection structure with the slider 7, the groove wheel 12 will be driven to rotate only when the elastic rope 14 is in a taut state. Therefore, the running stroke of the mainspring 13 can be smaller than the length of the elastic rope 14.

[0030] like Figure 3 and Figure 4 As shown, the inner wall of the push ring 6 is inclined near the bottom. By arranging its inner wall into an inclined surface, it is convenient to adapt to rocks or soils of different diameters, and when pushing the rock to be discharged, the force surface of the rock is more balanced and stable.

[0031] like Figure 2 and Figure 4 As shown, the inclined surface of the inner wall of the push ring 6 is fixedly connected with a plurality of protrusions 15, and the protrusions 15 are arranged in a conical shape. In order to further improve the stability between the push ring 6 and the rock or soil, the protrusions 15 are used to facilitate embedding in the rock or soil, thereby increasing the stability of the sample during the sampling process.

[0032] The working principle of the utility model is as follows: when the drill tube 1 is finished sampling, the drill tube 1 is first taken out, and then the transfer tube 2 is rotated to take it out, and then the pull ring 10 is pulled to drive the slider 7 to move downward through the steel wire 9, and the slider 7 drives the push ring 6 to move downward, and the thrust of the push ring 6 is utilized to facilitate the convenient removal of the rock sample, thereby reducing the damage to the integrity of the rock sample;

[0033] At the same time, the slider 7 drives the elastic rope 14 downward when moving downward, and the groove wheel 12 is tightened when the spring 13 rotates. When the rock sample is completely taken out, the pull ring 10 is released to drive the groove wheel 12 to reverse through the rotation of the spring 13, and the elastic rope 14 is wound up. The elastic rope 14 pulls the push ring 6 to reset through the slider 7, thereby achieving the purpose of reciprocating use.

[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
