DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following Figures 1-5 further describes the present application in detail with reference to the accompanying drawings.

[0024] An embodiment of the present application discloses a pipeline groove excavation tool. As Figure 1As shown in the figure, it includes a slotted vertebral body 1. A protective ring 9 is fixedly arranged at the edge position of the top of the slotted vertebral body 1. The inner wall of the protective ring 9 is in contact with the outer side of the outer guard plate 8. The protective ring 9 is higher than the bottom of the outer guard plate 8. The protective ring 9 prevents the outer slide plate 8 from rotating in the reverse direction and moving away from the edge of the slotted vertebral body 1 due to excessive movement, playing a role in protecting the outer slide plate 8. One side of the upper surface of the slotted vertebral body 1 is rotatably connected to the bottom of the outer guard plate 8 through a rotating rod. The inner wall of the power groove in the middle of the inner side of the outer guard plate 8 is rotatably connected to one end of a cross plate 3 through a rotating rod. The upper surface of the other end of the cross plate 3 is fixedly connected to the bottom of a power vertical rod 13. The outer circumferential surface of the top of the power vertical rod 13 is slidably connected to the arc track in the middle of the lower surface of a power circular plate 4. The middle of the lower surface of the power circular plate 4 is fixedly connected to the top of a rotating column 16. The bottom of the rotating column 16 is rotatably arranged in the middle of the upper surface of a bottom support plate 10. The bottom of the bottom support plate 10 is fixedly arranged in the middle of the upper surface of the slotted vertebral body 1 through a fixed column.

[0025] Please refer to Figure 1 , the thickness of the inner arc plate 2 is less than that of the outer guard plate 8. Limiting baffles are arranged at the positions of both ends of the inner arc plate 2 inside the outer guard plate 8. The relatively thin inner arc plate 2 is convenient for sliding inside the outer guard plate 8. At the same time, the limiting baffles are set to prevent the inner arc plate 2 from moving excessively and avoid the inner arc plate 2 detaching from the outer guard plate 8 during movement.

[0026] Please refer to Figure 2 , a spur gear 17 is fixedly sleeved on the outer circumference of the bottom of the rotating column 16. The spur gear 17 meshes with the teeth on one side of a rack 7 through the teeth on one side of its outer circumferential surface. The top of the rack 7 is fixedly connected to one end of a hydraulic rod 11 through a connecting plate. The other end of the hydraulic rod 11 is fixedly connected to the top of one side of a fixing plate 15. The bottom of the fixing plate 15 is fixedly arranged on the upper surface of the slotted vertebral body 1.

[0027] Please refer to Figure 3 , a cross bar 14 is slidably inserted into the middle of the rack 7. One end of the cross bar 14 is fixedly arranged in the middle of one side of the fixing plate 15. The cross bar 14 is arranged parallel to the hydraulic rod 11. The cross bar 14 ensures that the rack 7 can always move horizontally during lateral movement and avoids deviation during movement.

[0028] Please refer to Figure 2, five identical cross plates are arranged at the edge position of the bottom support plate 10. A trapezoidal chute is arranged on the upper surface of the cross plate. A trapezoidal slider is slidably arranged on the inner wall of the trapezoidal chute. The trapezoidal slider ensures smooth horizontal movement. A telescopic support column 12 is fixedly arranged at the top of the trapezoidal slider. The telescopic support column 12 is convenient for changing its length when the distance is changed. The top of the telescopic support column 12 is fixedly arranged at the bottom of the cross plate 3. The telescopic support column 12 is convenient for the cross plate 3 to support at all times during displacement. The cross plate at the edge position of the bottom support plate 10 is perpendicular to the inner wall of the vertical external protection plate 8, which is convenient for supporting the external protection plate 8 through the cross plate at the edge of the bottom support plate 10.

[0029] Please refer to Figure 4 , five identical arc-shaped tracks are fixedly arranged in the middle of the power circular plate 4. The width of the arc-shaped track is the same as the diameter of the power vertical rod 13. The top of the power circular plate 4 is rotatably arranged with a top connecting plate 6 through a bearing. A support rod 5 is fixedly arranged on the outside of the top connecting plate 6. The bottom of the support rod 5 is fixedly arranged on the upper surface of the grooved cone 1. The power circular plate 4 drives the power vertical rod 13 to move through the arc-shaped tracks in the middle. The support rod 5 ensures the stability of the power circular plate 4 during movement and prevents the power circular plate 4 from shifting during rotation.

[0030] Please refer to Figure 4 , the number of the external protection plates 8 is five. The five external protection plates 8 are evenly and rotatably arranged on one side of the grooved cone 1. Chutes are arranged on both sides of the external protection plate 8. Inner arc-shaped plates 2 are slidably arranged on the inner walls of the chutes. The two external protection plates 8 are slidably connected through the inner arc-shaped plates 2. Rotating the five identical external protection plates 8 on the top of the grooved cone 1 is convenient for the bottom of the external protection plate 8 to rotate on the top of the grooved cone 1, so as to change the diameter behind the tool and facilitate the excavation of a trench with a larger diameter.

[0031] The implementation principle of a pipe trench excavation machine in an embodiment of the present application is as follows: Place the grooved cone 1 at the position of the pipe trench excavation. The connecting fastener on one side of the top connecting plate 6 is connected to an external driving device. When it is necessary to excavate pipe trenches with different diameters, start the hydraulic rod 11 as the power to drive the power circular plate 4 to rotate through the rack 7 and the spur gear 17. The power circular plate 4 makes the power vertical rod 13 slide inside the arc-shaped track during rotation through the arc-shaped tracks in the middle. The power vertical rod 13 drives the cross plate 3 to move horizontally. The cross plate 3 pushes the top of the external protection plate 8 to move in an arc during movement. The circumference formed by the tops of the five external protection plates 8 expands, so as to achieve the effect of excavating a trench with a larger size.

[0032] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
