Detailed implementation manner

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-3 , this embodiment provides a technical solution: a bidirectional rotating stirring drill pipe, including a linkage bin 1 and an adjustable stirring mechanism 4;

[0022] Linkage bin 1: A rotating column 3 is rotatably connected to its upper end, a rotating cylinder 2 is rotatably connected to the lower end of the linkage bin 1, the rotating cylinder 2 is movably sleeved on the outer surface of the rotating column 3, and a spiral blade 9 is fixedly connected to the lower end of the rotating column 3. The spiral blade 9 is an inverted conical spiral blade;

[0023] Adjustable stirring mechanism 4: It includes a fixed cylinder 41, adjusting arms 42 and stirring blades 46. The fixed cylinder 41 is connected to the lower end of the outer surface of the rotating cylinder 2 by evenly distributed screws. The upper end of the fixed cylinder 41 is provided with evenly distributed first notches. Inside each of the first notches, an adjusting arm 42 is rotatably connected. The lower ends of the adjusting arms 42 are fixedly connected with stirring blades 46 respectively. The adjustable stirring mechanism 4 further includes an adjusting seat 43, connecting rods 44 and connecting seats 45. The adjusting seat 43 is slidably connected to the outer surface of the rotating cylinder 2. The lower end of the adjusting seat 43 is provided with evenly distributed second notches. Inside each of the second notches, a connecting rod 44 is rotatably connected. The connecting seats 45 are respectively fixedly connected to the middle parts of the upper surfaces of the adjusting arms 42. The connecting seats 45 are all rotatably connected to the lower ends of the vertically adjacent connecting rods 44. The adjustable stirring mechanism 4 further includes a driving cylinder 47 and an external thread 48. The external thread 48 is arranged in the middle of the outer surface of the rotating cylinder 2. The middle part of the external thread 48 is threadedly connected to the inside of the driving cylinder 47. The lower end of the driving cylinder 47 is rotatably connected to the upper end of the adjusting seat 43. According to the requirements of the drilling diameter and the stirring range, rotate the driving cylinder 47. Under the action of the external thread 48, the driving cylinder 47 moves downward. The downward movement of the driving cylinder 47 drives the adjusting seat 43 to move downward. The downward movement of the adjusting seat 43 drives the upper ends of the connecting rods 44 to move downward, so that the connecting rods 44 all push the corresponding adjusting arms 42 to rotate through the vertically adjacent connecting seats 45. The adjusting arms 42 all rotate in a direction away from the center of the rotating cylinder 2. The outward rotation of the adjusting arms 42 all drives the vertically adjacent stirring blades 46 to rotate outward, realizing the adjustment of the coverage range of the stirring blades 46;

[0024] Wherein: Transmission shafts 5 are rotatably connected to both the left and right ends of the linkage bin 1. One ends of the transmission shafts 5 close to the center of the linkage bin 1 are fixedly connected with transmission gears 6 respectively. The upper end of the rotating cylinder 2 is fixedly connected with a driven gear 7. Both of the two transmission gears 6 are meshed with the driven gear 7. The upper end of the rotating column 3 is fixedly connected with a driving gear 8. Both of the two transmission gears 6 are meshed with the driving gear 8. The rotation of the rotating column 3 is realized by an external driving device. The rotation of the rotating column 3 drives the driving gear 8 to rotate. Then both of the two transmission gears 6 rotate under the action of the corresponding transmission shafts 5. The rotation of the transmission gears 6 drives the driven gear 7 to rotate. The rotation of the driven gear 7 drives the rotating cylinder 2 to rotate. The rotating directions of the rotating cylinder 2 and the rotating column 3 are opposite. The rotation of the rotating column 3 drives the spiral blade 9 to rotate, facilitating the drilling work of the bidirectional rotating stirring drill rod. At the same time, the rotation of the rotating cylinder 2 drives the fixed cylinder 41 to rotate, and then drives the evenly distributed adjusting arms 42 to rotate around the central axis of the rotating cylinder 2. The rotation of the adjusting arms 42 all drives the corresponding stirring blades 46 to rotate around the central axis of the rotating cylinder 2, realizing the stirring work while performing the drilling work with a specified hole diameter;

[0025] Among them: The upper end of the linkage bin 1 is fixedly connected with a support plate 10 through uniformly distributed struts. An installation plate 13 is arranged at the upper end of the support plate 10. Uniformly distributed installation holes are arranged inside the installation plate 13. Handles are fixedly connected to both the front and rear ends of the linkage bin 1. Uniformly distributed shock-absorbing dampers 11 are arranged between the support plate 10 and the installation plate 13. Uniformly distributed springs 12 are fixedly connected between the support plate 10 and the installation plate 13. The springs 12 are all movably sleeved on the outer surface of the vertically adjacent shock-absorbing dampers 11. Under the shock-absorbing effect of the shock-absorbing dampers 11, the shock-absorbing performance of the bidirectional rotating mixing drill pipe during work is improved.

[0026] The working principle of a bidirectional rotating mixing drill pipe provided by the present utility model is as follows: During work, personnel stably connect the installation holes with the threaded holes of external driving equipment through bolts, and then stably connect the output shaft of the external driving equipment and the rotating column 3 through a coupling. Then, according to the requirements of the drilling diameter and mixing range, personnel rotate the driving cylinder 47. Under the action of the external thread 48, the driving cylinder 47 moves downward. The downward movement of the driving cylinder 47 drives the adjusting seat 43 to move downward. The downward movement of the adjusting seat 43 drives the upper end of the connecting rod 44 to move downward, so that the connecting rods 44 all push the corresponding adjusting arms 42 to rotate through the vertically adjacent connecting seats 45. The adjusting arms 42 all rotate in a direction away from the center of the rotating cylinder 2. The outward rotation of the adjusting arms 42 all drives the vertically adjacent mixing blades 46 to rotate outward, realizing the adjustment of the coverage range of the mixing blades 46. When the mixing blades 46 rotate to the required position state, personnel stop rotating the driving cylinder 47. Then, personnel rotate the rotating column 3 through the external driving equipment. The rotation of the rotating column 3 drives the driving gear 8 to rotate, and further enables both transmission gears 6 to rotate under the action of the corresponding transmission shafts 5. The rotation of the transmission gears 6 drives the driven gears 7 to rotate. The rotation of the driven gears 7 drives the rotating cylinder 2 to rotate. The rotating directions of the rotating cylinder 2 and the rotating column 3 are opposite. The rotation of the rotating column 3 drives the spiral blade 9 to rotate, facilitating the drilling work of the bidirectional rotating mixing drill pipe. At the same time, the rotation of the rotating cylinder 2 drives the fixed cylinder 41 to rotate, and further drives the uniformly distributed adjusting arms 42 to rotate around the central axis of the rotating cylinder 2. The rotation of the adjusting arms 42 all drives the corresponding mixing blades 46 to rotate around the central axis of the rotating cylinder 2, realizing the mixing work while performing the drilling work of a specified hole diameter. At the same time, under the shock-absorbing effect of the shock-absorbing dampers 11, the shock-absorbing performance of the bidirectional rotating mixing drill pipe during work is improved.
