Description

Technical Field

[0001] The present application relates to the technical field of equipment for hydrogeological exploration, and more specifically, to a rapid drilling device for hydrogeological exploration. Background Art

[0002] When conducting hydrogeological surveys, the rapid and accurate acquisition of underground information is related to the reliability of the entire exploration results. Therefore, in order to improve exploration efficiency and ensure the reliability of exploration results, relevant staff often use fast drilling devices for hydrogeological surveys to quickly and accurately obtain underground soil and rock sample information.

[0003] The document with the prior art publication number CN217632246U provides a portable drilling device for hydrogeological drilling, which is stable and easy to operate during drilling work, and has the characteristics of being detachable and can effectively reduce the volume during transportation, making it easy to carry.

[0004] Although the above-mentioned existing technical solutions have the function of geological drilling, they still have the following defects: when drilling with the above-mentioned technical solutions, the user needs to manually hold the handle to push the drill rod downward to ensure that the drill rod is drilled smoothly. However, in the process of geological drilling, workers often need to drill holes in hard rocks, which not only requires high physical strength of the workers, but also has low efficiency and is difficult to complete the drilling work quickly. In view of this, we propose a fast drilling device for hydrogeological exploration. Utility Model Content

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The embodiment of the present application discloses a rapid drilling device for hydrogeological exploration, comprising: a mounting seat 1, a drilling mechanism is installed on the mounting seat 1, the drilling mechanism includes a connecting seat 12, a drill rod 5 is detachably installed on one side of the connecting seat 12, a rotating mechanism is installed on one side of the drill rod 5, the rotating mechanism is used to drive the drill rod 5 to rotate, a driving frame 16 is installed on one side of the drill rod 5, a fixed frame 14 is fixed on the mounting seat 1, a screw rod 2 is rotatably connected to the fixing frame 14, the driving frame 16 is threadedly connected to the screw rod 2, the driving frame 16 is limited by the fixing frame 14 and is slidably connected thereto, a driven gear 6 is fixedly connected to the end of the screw rod 2, a connecting rod 9 is also rotatably connected to the mounting seat 1, a handle 4 is installed on one side of the connecting rod 9, a driving gear 3 is sleeved and fixed on the connecting rod 9, the driving gear 3 is meshed and connected with the driven gear 6, and the diameter of the driving gear 3 is smaller than the diameter of the driven gear 6.

[0029] The rotating mechanism includes an electric motor 11 fixedly mounted on a mounting base 1, a spline rod 10 being fixedly connected to the output end of the electric motor 11, a spline cylinder 13 being sleeved on the outer side of the spline rod 10, the spline cylinder 13 being fixedly connected to a connecting base 12, and the spline cylinder 13 being restricted by a driving frame 16 and being rotationally connected therewith.

[0030] The staff aligns the drill rod 5 to the designated position, and under the action of the motor 11, the spline rod 10 drives the spline cylinder 13 and the drill rod 5 to rotate. The staff holds the handle 4 to rotate the connecting rod 9, and the driving gear 3 rotates. Since the driving gear 3 is meshed with the driven gear 6 and the diameter of the driving gear 3 is smaller than the diameter of the driven gear 6, the screw 2 rotates, and the driving frame 16 then drives the spline cylinder 13 and the drill rod 5 to move downward.

[0031] This method enables the staff to drill the drill rod 5 into the hard ground easily and quickly, greatly reducing the drilling difficulty and effectively improving the drilling efficiency.

[0032] Reference Figure 1 and Figure 2 A telescopic rod 7 is fixedly installed on one side of the handle 4. By adjusting the length of the telescopic rod 7, the staff can rotate the connecting rod 9 more effortlessly. The other end of the telescopic rod 7 is connected and fixed to the connecting rod 9.

[0035] While the driving frame 16 drives the drill rod 5 to move downward, under the action of the slide bar 15 and the spring 17, the protective tube 8 can always be tightly covered on the outside of the drill rod 5, reducing the probability of stones scattering and effectively improving the safety of the technical solution.

[0036] The present application provides a screw rod 2, a driving gear 3 and a driven gear 6, so that the staff can easily and quickly drill the drill rod 5 into the hard ground, greatly reducing the difficulty of drilling; and by providing a protective tube 8 and a spring 17, it can prevent the stones generated during the drilling process from splashing randomly, effectively improving the safety of the present technical solution.

[0037] The implementation principle of the fast drilling device for hydrogeological exploration in the embodiment of the present application is as follows: when the relevant staff needs to use the technical solution for geological drilling, the staff first aligns the drill rod 5 with the designated position, and under the action of the motor 11, the spline rod 10 drives the spline cylinder 13 and the drill rod 5 to rotate. Then the staff holds the handle 4 to rotate the connecting rod 9, the driving gear 3 drives the screw 2 to rotate, and the driving frame 16 then drives the spline cylinder 13 and the drill rod 5 to move downward.

[0038] During the period when the driving frame 16 drives the drill rod 5 to move downward, under the action of the slide bar 15 and the spring 17, the protective tube 8 can always be tightly covered on the outside of the drill rod 5, reducing the probability of stones scattering. In this way, the geological drilling operation can be completed.
