The top of the drilling rod 202 is movably connected to a lifting plate 205 through a bearing. The top of the lifting plate 205 is fixedly connected to a second motor 207. The top of the drilling rod 202 passes through the lifting plate 205 and is drivingly connected to the output shaft of the second motor 207.

[0026] The buffer mechanism 6 includes a damper 601, which is located at the top of the fixed block 4 and fixedly connected to the fixed block 4, the top of the damper 601 is fixedly connected to the bottom of the pillar 3, the surface of the damper 601 is sleeved with a buffer spring 602, the top of the buffer spring 602 is fixedly connected to the bottom of the pillar 3, and the bottom of the buffer spring 602 is fixedly connected to the top of the fixed block 4.

[0027] like Figure 1-4 As shown, the placement plate 1 is used to support and fix the components on the top to improve the stability of each component when in use. The drilling mechanism 2 is used to perform ground drilling work in order to collect geological samples. The support pillar 3, the fixing block 4 and the universal wheel 5 cooperate to facilitate the movement of the placement plate 1. The buffer mechanism 6 can buffer the vibration generated by the placement plate 1 during the movement and reduce the vibration amplitude of the placement plate 1 during the movement, which can not only reduce the burden on the staff's arms, but also prevent the internal parts of the drilling mechanism 2 from loosening, thereby ensuring that the drilling work can be carried out normally and preventing unnecessary trouble caused by the loosening of the internal parts of the drilling mechanism 2.

[0028] Example 2

[0029] Reference Figure 3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0030] In this embodiment, a protection box 203 is fixedly connected to the right side of the top of the placement plate 1, the inner cavity of the protection box 203 is movably connected to a threaded rod 204 through a bearing, and the lifting plate 205 is threadedly connected to the surface of the threaded rod 204.

When the threaded rod 204 rotates, the height of the lifting plate 205 can be adjusted, so that it drives the drilling rod 202 and the second motor 207 to descend. When the drilling rod 202 descends, it can gradually drill into the ground to carry out sampling work.

[0033] Example 3

[0034] Reference Figure 2 and 4 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0035] In this embodiment, the front and rear ends of the top of the fixing block 4 are fixedly connected with positioning columns 603 , and the top of the positioning columns 603 penetrates into the inner cavity of the pillar 3 and is slidably connected with the inner cavity of the pillar 3 .

[0036] A support rod 604 is fixedly connected to one side of the pillar 3 , and a positioning pin 605 is slidably connected to the inner cavity of the support rod 604 .

[0038] like Figure 2 and 4 As shown, when the placement plate 1 vibrates during operation, the buffer spring 602 will be deformed due to compression, and the return elastic force of the buffer spring 602 can cooperate with the damper 601 to buffer the vibration, thereby reducing the vibration amplitude of the placement plate 1. The positioning column 603 is used to limit the fixed block 4 to prevent its angle from deflecting. The support rod 604 is used to support the positioning pin 605. After the positioning pin 605 is inserted into the ground, the position of the entire device can be fixed to ensure the stability of the drilling penetration.

[0039] When in use, when the placement plate 1 vibrates during operation, the buffer spring 602 will be deformed due to compression, and the return elastic force of the buffer spring 602 can cooperate with the damper 601 to buffer the vibration, thereby reducing the vibration amplitude of the placement plate 1. When drilling work is required, first take out the auxiliary plate 606 from the inside of the placement groove 607, and insert the positioning pin 605 into the figure to fix the position of the placement plate 1, and then start the first motor 206 and the second motor 207. The second motor 207 is used to drive the drilling rod 202 to rotate. When the first motor 206 is in operation, it can drive the threaded rod 204 to rotate. When the threaded rod 204 rotates, it can adjust the height of the lifting plate 205, so that it drives the drilling rod 202 and the second motor 207 to descend. When the drilling rod 202 descends, it can gradually drill into the ground to carry out sampling work.
