Description

Technical Field

[0002] Sampling equipment in geological exploration is mainly used to collect rock, soil, water and other samples for subsequent experiments and analysis.

[0004] To overcome these shortcomings, prior art (Chinese patent publication number: CN218916887U, application date: November 18, 2022) discloses a field outcrop sampling device for geological exploration. This device utilizes rollers installed under the base plate to enable flexible movement of the entire device. Hydraulic legs increase the device's grip when drilling in hard geological conditions, preventing the device from tipping over. When not in use, the hydraulic legs can be folded onto the base plate, preventing the device from moving.

[0005] The existing technology connects the motor and the drilling equipment through an elastic coupling, thereby reducing the impact of the vibration generated by the equipment during drilling on the equipment. In actual use, when the elastic coupling is used to connect the motor and the drilling equipment, the elastic coupling achieves a shock-absorbing effect through the deformation of its own internal structure. However, due to the high vibration frequency and intensity of drilling, the service life of the elastic coupling is shortened, which increases the cost of equipment use. Utility Model Content

[0039] Example 2:

[0040] Based on the first embodiment, the specific working principle is as follows:

[0041] The field outcrop sampling equipment for geological exploration, during the operation of the equipment, the motor on the top of the top plate 1 drives the transmission shaft 9 to rotate, so that the transmission shaft 9 drives the driving shaft 10 at its lower end to rotate, and during the rotation of the driving shaft 10, the drilling rod 11 is driven to rotate, and at the same time the drilling rod 11 moves downward to drill holes for sampling geological structures. During the rotation of the transmission shaft 9, two continuous universal joint structures are formed at the connection points between the upper connecting rod 902 and the lower connecting rod 903 and the central connecting rod 901, respectively, so that the transmission shaft 9 can move arbitrarily within a certain range through the two continuous universal joint structures. When the drilling rod 11 performs the drilling operation, the vibration of the drilling rod 11 will be absorbed by the arbitrary movement of the transmission shaft 9 itself and the up and down movement of the drilling rod 11 on the outside of the driving shaft 10, thereby reducing the impact of the vibration of the drilling rod 11 on the equipment;

[0042] The transmission rod 19 is driven to rotate by the dual-axis motor 18, so that the two transmission rods 19 transmit power to the bevel gear ring on the outside of the screw rod 17 through the bevel gear, thereby driving the two screw rods 17 to rotate between the top plate 1 and the bottom plate 2 through the dual-axis motor 18. During the rotation of the screw rod 17, the screw rod 17 simultaneously rotates inside the limit sleeve 13 in the middle of the drive plate 12, thereby driving the drive plate 12 to move up and down on the screw rod 17. The up and down movement of the drive plate 12 drives the movable plate 8 to move up and down between the four support rods 3, thereby adjusting the vertical position of the drilling rod 11 on the outside of the drive shaft 10, so that the drilling rod 11 moves downward to complete the drilling operation. At the same time, during the movement of the drive plate 12, the two positioning sleeves 14 will slide on the outside of the support rod 3. Since the movable plate 8 and the drive plate 12 are connected to each other by the connecting piece 15, when the drilling rod 11 vibrates, it will drive the movable plate 8 to vibrate. The connecting piece 15 set between the movable plate 8 and the drive plate 12 reduces the impact of the vibration on the drive plate 12, thereby improving the stability of the equipment operation.

[0043] Pull the handle on the top of the moving frame 4, so that the entire structure formed by the top plate 1, the bottom plate 2, the support rod 3 and the moving frame 4 is tilted to a certain angle around the support wheel 7, presenting the following Figure 1 In the state shown, the support wheel 7 can be driven to move by pulling the handle on the top of the moving frame 4, thereby facilitating the movement of the entire device. At the same time, when the device needs to be placed in a fixed location, the support legs 6 and the support wheels 7 are placed on the same horizontal plane, so that the entire device is flush with the ground, thereby realizing rapid deployment of the device.
