Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically to a geological exploration sampling device. Background Technology

[0002] During drilling and sampling, core samples are extracted from the rock formations to facilitate testing. According to the publication (announcement) number CN113865919A, published (announcement) date: 2021-12-31, an ecological environment geological exploration sampling device is disclosed. Its structure includes a sampling mechanism, a main body, a sealing cover, a connecting shaft, and a mounting base. The upper end of the sampling mechanism is fixedly embedded in the lower outer wall of the main body. The lower outer wall of the sealing cover is nested and fitted into the upper outer wall of the main body. The lower outer wall of the connecting shaft is movably fitted into the upper outer wall of the mounting base. When this invention is used to sample geological soil in the ecological environment, the sampling rotor of the device will start when the device is started. The starting of the sampling rotor will excavate the soil. The soil excavated and entering the sampling rotor will enter the collection mechanism due to the conduction of the sampling rotor. After the soil contacts the front surface of the flow-limiting plate, the flow-limiting plate will block the soil, causing the first soil to enter to be blocked and flow back to both ends, thereby maximizing the removal of impurities inside the soil and surface dust, avoiding soil contamination and subsequent data deviations in testing.

[0003] In existing patents that include the above-mentioned technologies, the sampling tool used is a cylindrical drill barrel for sampling. The structure is simple, but there is a lot of sampling debris generated during the sampling process. Utility Model Content

[0004] The purpose of this invention is to provide a geological exploration sampling device to address the aforementioned shortcomings in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a geological exploration sampling device, including a base, a support plate fixedly connected to the top of the base, a hydraulic telescopic cylinder fixedly installed on the upper surface of the support plate, a push rod fixedly installed at the output end of the hydraulic telescopic cylinder, a drilling mechanism fixedly connected to the bottom end of the push rod, a protective cover slidably arranged on the periphery of the push rod, a first spring arranged between the protective cover and the lower surface of the support plate, a retaining ring fixedly connected to the periphery of the protective cover, and elastic stops arranged on both sides of the inner wall of the base;

[0006] The drilling mechanism includes a mounting frame fixedly connected to the bottom end of the push rod, a motor fixedly mounted on the mounting frame, a three-jaw chuck fixedly mounted on the output end of the motor, and a drill bit fixedly mounted on the three-jaw chuck.

[0007] Preferably, the mounting bracket includes an upper mounting plate and a lower mounting plate, with four L-shaped connecting plates fixedly connected between the upper and lower mounting plates. The bottom end of the push rod is fixedly connected to the upper surface of the upper mounting plate, and the motor is fixedly mounted on the upper surface of the lower mounting plate.

[0008] Preferably, the elastic stop includes a fixed plate, a movable plate is slidably disposed on the upper surface of the fixed plate, a second spring is disposed between one side of the movable plate and the inner wall of the base, one end of the second spring is fixedly connected to one side of the movable plate, and the other end of the second spring is fixedly connected to the inner wall of the base.

[0009] Preferably, the upper surface of the fixed plate is provided with a T-shaped groove, and a T-shaped slider is slidably disposed inside the groove, with the top end of the slider being fixedly connected to the lower surface of the movable plate.

[0010] Preferably, the end of the movable plate has an isosceles triangular structure.

[0011] In the above technical solution, the geological exploration sampling equipment provided by this utility model, when the drilling mechanism moves downward to drill the hole, the push rod drives the protective cover to rise. When the drilling mechanism moves downward to drill the hole, the push rod drives the protective cover to fall.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-6 This utility model provides a geological exploration sampling device, including a base 1, a support plate 2 fixedly connected to the top of the base 1, a hydraulic telescopic cylinder 3 fixedly installed on the upper surface of the support plate 2, a push rod 4 fixedly installed at the output end of the hydraulic telescopic cylinder 3, a drilling mechanism fixedly connected to the bottom end of the push rod 4, a protective cover 5 slidably arranged on the periphery of the push rod 4, a first spring 6 arranged between the protective cover 5 and the lower surface of the support plate 2, a retaining ring 7 fixedly connected on the periphery of the protective cover 5, and elastic stops arranged on both sides of the inner wall of the base 1. On the movement path of the drilling mechanism, the retaining ring 7 contacts the elastic stops.

[0023] When the drilling mechanism moves downward to drill the hole, the push rod drives the protective cover 5 to rise. When the drilling mechanism moves downward to drill the hole, the push rod drives the protective cover 5 to fall. The retaining ring 7 first contacts the elastic stop to prevent the protective cover 5 from blocking the operator's view before the drilling mechanism is aligned with the rock column. It will not affect the alignment of the drilling mechanism with the rock column. There is no need to manually open or close the protective cover 5, which reduces the production process.

[0024] The drilling mechanism includes a mounting frame 8 fixedly connected to the bottom end of the push rod 4. A motor 9 is fixedly mounted on the mounting frame 8. A three-jaw chuck 10 is fixedly mounted on the output end of the motor 9. A drill bit 11 is fixedly mounted on the three-jaw chuck 10. The mounting frame 8 includes an upper mounting plate and a lower mounting plate. Four L-shaped connecting plates are fixedly connected between the upper mounting plate and the lower mounting plate. The bottom end of the push rod 4 is fixedly connected to the upper surface of the upper mounting plate, and the motor 9 is fixedly mounted on the upper surface of the lower mounting plate.

[0025] Secondly, the elastic stop includes a fixed plate 12, a movable plate 13 is slidably disposed on the upper surface of the fixed plate 12, a second spring 14 is disposed between one side of the movable plate 13 and the inner wall of the base 1, one end of the second spring 14 is fixedly connected to one side of the movable plate 13, and the other end of the second spring 14 is fixedly connected to the inner wall of the base 1, a T-shaped groove is opened on the upper surface of the fixed plate 12, a T-shaped slider 15 is slidably disposed inside the groove, the top end of the slider 15 is fixedly connected to the lower surface of the movable plate 13, and the end of the movable plate 13 is an isosceles triangle structure, which facilitates the retaining ring 7 to push open the elastic stop.

[0026] In the above technology, the two elastic stops release elastic force to both sides respectively. When the drilling mechanism moves downward to drill the hole, the push rod 4 drives the protective cover 5 to fall. The retaining ring 7 first contacts the elastic stops. When the pushing force of the push rod 4 is greater than the resistance of the elastic stops, the retaining ring 7 pushes the two elastic stops apart, and the protective cover 5 continues to fall. The first spring 6 plays the role of holding the protective cover 5, and it will not affect the upward rebound of the protective cover 5 when the protective cover 5 contacts the rock column.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
