[0031] One of support plates 13 is fixedly connected to the top of support frame 3, and the other support plate 13 is fixedly connected to the top of one of sliding blocks 5. A plurality of balls 15 are embedded in the interiors of the two support plates 13. Through the arrangement of the support plates 13, the drill rod 10 can be supported to prevent it from sagging under the action of gravity after being released from clamping and affecting the quality of drilling. Through the arrangement of the balls 15, the friction between the drill rod 10 and the support plates 13 can be reduced.

[0032] The moving component includes a slide 16, which is opened at the top of the electric lifting platform 2. An electric push rod 17 is fixedly installed inside the slide 16. The telescopic end of the electric push rod 17 is fixedly connected to a push plate 18. The push plate 18 is slidably connected to the slide 16, and the push plate 18 is fixedly connected to the bottom of the support frame 3. Through the coordinated use of structures such as the electric lifting platform 2, the slide 16, the electric push rod 17 and the push plate 18, the position of the drill bit 12 during use can be adjusted up and down and left and right, which is convenient and quick, and there is no need to move the entire device for adjustment, thereby improving the practicality of the device.

[0033] The rotating assembly includes a motor 19 and a gear ring 20. The motor 19 is fixedly installed on one side of one of the fixed plates 6. The output end of the motor 19 is fixedly connected to a gear 21. The gear ring 20 is fixedly sleeved on the outer surface of the rotating ring 7. The gear 21 is engaged with the gear ring 20. Through the setting of the rotating assembly, the rotating ring 7 and the clamped drill rod 10 can be driven to rotate synchronously, thereby causing the drill bit 12 to rotate, and with the cooperation of structures such as the motor 2 22 and the guide rod 4, it can be drilled into the soil.

Through the setting of the driving assembly, it can drive one of the sliders 5 and the drill bit 12 to move after rotation to perform drilling work.

[0035] Working principle: During operation, the drilling position of the drill bit 12 can be adjusted according to the position of the pipeline to be laid, that is, after the electric lifting platform 2 is started, it drives the support frame 3 to move up and down synchronously, and can synchronously drive the drill bit 12 to move up and down, and adjust its use height. The electric push rod 17 is started to extend or retract its telescopic end, driving the push plate 18 to slide inside the slide groove 16. The push plate 18 drives the support frame 3 and the drill bit 12 and other structures to move synchronously, so that the horizontal position of the drill bit 12 when in use can be adjusted left and right;

[0036] After adjusting the use position of the drill bit 12, start the motor 19 to drive the gear 21 to rotate, the gear 21 drives the gear ring 20 meshing with it to rotate, the gear ring 20 drives the rotating ring 7, the clamped drill rod 10 and the drill bit 12 to rotate synchronously, and then start the motor 22 to drive the threaded rod 23 to rotate. Under the guiding and limiting action of the guide rod 4, the slider 5 threadedly connected to the threaded rod 23 drives the corresponding fixed plate 6, rotating ring 7, clamping plate 9, drill rod 10 and drill bit 12 to move synchronously along the axial direction of the threaded rod 23, and cooperate with the rotating drill bit 12 to perform drilling work. During the drilling process, after one section of the drill rod 10 has been partially drilled into the soil, another new section can be taken out. The drill rod 10 is inserted into the support plate 13 on the other slider 5, and the other end that matches the thread groove 11 is threadedly connected to the thread groove 11. Then the hydraulic cylinder 8 is started to drive the clamping plate 9 to move up. After the clamping of the corresponding drill rod 10 is released, the motor 22 is started to drive the threaded rod 23 to reverse, and the corresponding slider 5 and the rotating ring 7 can be moved to the side close to the spring 14. In the process of moving, after squeezing the other slider 5 and the spring 14, the newly added drill rod 10 can be clamped and fixed near one end by the hydraulic cylinder 8 again, and the drill bit 12 and the drill rod 10 partially drilled into the soil can be used to drill again to increase the length of the drill hole.
