[0004] However, when the device is actually used, the soil is easily stuck in the mobile sampling drill bit, which makes it inconvenient to remove the soil. An operator or other mechanical structure is required to remove the soil, which is inconvenient to operate the device. At the same time, the device is prone to tilting during use, and the stability of the device during use is relatively low. Utility Model Content

[0005] The main purpose of the utility model is to provide a sampling device for geological exploration, which can effectively solve the problems of inconvenient device operation and relatively low device stability.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A sampling device for geological exploration, comprising a device base, a plurality of support rods are fixed in a circular array on the upper end of the device base, a limiting frame is fixed on the upper ends of the plurality of support rods, a sliding plate is slidably mounted on the outer surfaces of the plurality of support rods, and a sampling assembly is provided at the lower end of the sliding plate;

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 - Figure 5 As shown, a sampling device for geological exploration includes a device base 1, and the four corners of the upper end of the device base 1 are slidably mounted with fixed legs 11 penetrating downwards, such as Figure 2 As shown, the lower part of the fixed leg 11 is pointed, which can facilitate the insertion of the fixed leg 11 into the ground. At the same time, due to the design of multiple fixed legs 11, it is convenient to fix the device during sampling. The upper ends of the multiple fixed legs 11 are fixed with limiting blocks 12, and a reset spring 13 is fixed between the limiting block 12 and the device base 1 and is sleeved on the outer surface of the fixed leg 11. The limiting block 12 is used for the installation of the reset spring 13. When the fixed leg 11 moves downward relative to the device base 1 (that is, when the fixed leg 11 is inserted into the ground), the multiple reset springs 13 can shrink. At the same time, the reset spring 13 facilitates the pulling out of the fixed leg 11 from the ground when resetting. The upper end of the device base 1 is also fixed with multiple support rods 14 in a circular array, and the upper ends of the multiple support rods 14 are jointly fixed with a limiting frame 15.

[0023] In addition, a sliding plate 16 is slidably installed on the outer surfaces of multiple support rods 14. Multiple support rods 14 are used for installing the sliding plate 16 and for supporting the sliding plate 16. The sliding plate 16 can move horizontally up and down. The limit frame 15 is used to limit the sliding plate 16 so that the sliding plate 16 can always be slidably connected to the support rods 14 when the device is in use, preventing the support rods 14 from being separated from the sliding plate 16, thereby affecting the normal operation of the device. A sampling component 2 for sampling is provided at the lower end of the sliding plate 16, and an operating handle 18 is also fixed to the upper end of the sliding plate 16. Due to the fixed connection between the sliding plate 16 and the operating handle 18, the device can move the sliding plate 16 horizontally up and down by pressing down the operating handle 18 when in use.

[0024] like Figure 2 - Figure 5As shown, the sampling assembly 2 includes a sampling square tube 21 fixed to the middle part of the lower end of the sliding plate 16, and the sampling square tube 21 also penetrates downwardly into the device base 1. The sampling square tube 21 is fixedly connected to the sliding plate 16, so that when the sliding plate 16 moves downward, the sampling square tube 21 will also move downward. A mounting groove 1 22 is provided on the outer surface of the sampling square tube 21, and a mounting groove 23 is also provided on the vertical surface of the inner cavity of the mounting groove 12. A rotating plate 24 for sealing the mounting groove 1 22 is also rotatably installed in the inner cavity of the mounting groove 12. When the device is sampling soil, the rotating plate 24 seals the mounting groove 1 22 to prevent the soil from coming out through the mounting groove 1 22. At the same time, when the soil sampling is completed, only the rotating plate 24 needs to be opened. Then, due to the inclined design of the rotating plate 24 when it is opened, the soil in the sampling square tube 21 will fall out of the sampling square tube 21 along the inclined rotating plate 24.

[0025] In addition, a pulley 25 is rotatably installed on the upper side of the inner surface of the mounting groove 23. The pulley 25 is connected to the rotating shaft of the rotating plate 24 through a transmission belt, so that the rotating plate 24 can drive the pulley 25 to rotate when it rotates. A gear 26 is also fixed to one end of the pulley 25. The gear 26 is fixedly connected to the pulley 25, so that the rotating plate 24 can also drive the rotating plate 24 to rotate when it rotates. At the same time, the gear 26 can also drive the rotating plate 24 to rotate when it rotates. A mounting bracket 27 is fixed to the outer surface of the sampling square tube 21. A gear 28 meshing with the gear 1 26 is rotatably installed on one end of the mounting bracket 27. The mounting bracket 27 is used for the installation of the gear 2 28.

[0026] Due to the design that gear 2 28 is meshed with gear 1 26, gear 1 26 and gear 2 28 can rotate at the same time. A rack 29 meshing with gear 2 28 is also fixed to the upper end of the device base 1. Since the rack 29 is fixed to the upper end of the device base 1, the sampling square tube 21 can rotate through the mutual meshing between gear 2 28 and the rack 29 when moving downward.

[0027] The specific implementation of this embodiment is as follows: when the device is used, it is first placed on the ground where sampling is required, and then the operating handle 18 is pressed downward. Due to the design of the fixed connection between the sliding plate 16 and the operating handle 18, the sliding plate 16 moves downward horizontally, and the multiple fixed legs 11 also move downward horizontally. Due to the design of the pointed ends of the fixed legs 11, the multiple fixed legs 11 can be inserted into the ground, preventing the device from shaking during sampling, thereby affecting the sampling effect;

[0028] When the sampling square tube 21 moves downward, the gear 2 28 and the rack 29 mesh with each other, so that the gear 2 28 rotates, and then the gear 1 26 and the pulley 25 cooperate with each other, so that the rotating plate 24 rotates and the mounting groove 1 22 is sealed, and then the sampling square tube 21 is inserted into the ground to sample the soil;

[0029] When the sampling square tube 21 is taken out of the soil, the rack 29 cooperates with the gear 2 28 to make the rotating plate 24 rotate in the opposite direction, and then changes from a vertical state to an inclined state (the inclined state is as shown in FIG. Figure 3 As shown in the figure, the soil on the top of the sampling square tube 21 will fall down along the rotating plate 24. At the same time, the rotating plate 24 will also make the soil in the sampling square tube 21 soft when rotating, preventing the soil in the sampling square tube 21 from being stuck in the sampling square tube 21 and unable to fall out, thereby inconveniently operating the device.

[0030] It should be noted that the specific installation method, circuit connection method and control method of the return spring 13 and the gear, rack 29, etc. in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
