[0010] According to the above technical solution, the output end of the driving motor passes through the top of the lifting driving frame and extends to the bottom of the lifting driving frame and is fixedly connected to the top of the rotating disk.

[0011] According to the above technical solution, the telescopic end of the electric telescopic rod passes through the top of the fixed disc and extends to the bottom of the fixed disc and is fixedly connected to the top of the auxiliary lifting disc. A circular groove is opened in the middle of the fixed disc, and the fixed disc is slidably connected to the outer wall of the drive shaft through the circular groove.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when digging a hole for tree planting is required, the present invention moves the device to a designated position, then controls the hydraulic lifting rod to work, so that the digging drill bit can contact the soil, turns on the drive motor, and the drive motor controls the rotating disc and the digging drill bit to rotate during operation, and digs a hole in the soil, and then controls the hydraulic lifting rod to continue to descend, so that the digging drill bit provides an auxiliary downward force when digging a hole, and does not tilt when digging a hole; As the digging work progresses, when a pit that is wide at the top and narrow at the bottom needs to be dug, the driving motor controls the rotation of the digging drill bit, and at this time controls the electric telescopic rod to work. When the electric telescopic rod works, the electric telescopic rod pushes the auxiliary lifting plate, and then the adjustment frame on the auxiliary lifting plate synchronously pushes the connecting arm. When the connecting arm is stressed, the auxiliary frame is squeezed, so that the auxiliary frame pushes the arc-shaped water tank. At this time, the soil-dividing blades on the arc-shaped water tank are inclined to dig the soil, which can expand the diameter of the upper side when digging the pit; As the digging work proceeds, the driving motor controls the digging drill to rotate. When the digging drill rotates, the arc-shaped water tank rotates accordingly, generating centrifugal force during the rotation. At this time, water is pre-filled into the arc-shaped water tank through the water inlet pipe. As the arc-shaped water tank rotates, the water in the arc-shaped water tank directly leaks out through the pressure valve in the drainage hole, and can contact with the soil, reducing the density of the soil, making digging more labor-saving; When the driving motor controls the rotating disc to rotate, centrifugal force is generated in the rotating disc, which stretches the spring. At the same time, the spring pushes the sliding plate, so that the slider on the sliding plate slides in the sliding groove in the rotating disc. At the same time, the sliding plate pushes the moving column and the bulldozer, so that the bulldozer can push the soil on the upper side of the pit to the outside when digging, so as to prevent the soil from accumulating and re-entering the pit.

[0021] See also Figure 1-7The present invention provides a technical solution: the digging component 7 includes a driving shaft 701, a digging drill bit 702, a positioning rotating frame 703, a fixed disc 704, an electric telescopic rod 705, an auxiliary lifting plate 706 and an adjusting frame 707. The driving shaft 701 is fixedly connected to the middle of the bottom of the rotating disc 601, the digging drill bit 702 is fixedly connected to the bottom of the driving shaft 701, the positioning rotating frame 703 is fixedly connected to the top of the digging drill bit 702, the fixed disc 704 is fixedly connected to the outside of the driving shaft 701, the electric telescopic rod 705 is fixedly connected to the top of the fixed disc 704, the electric telescopic rod 705 has a telescopic end, the auxiliary lifting plate 706 is fixedly connected to the telescopic end of the electric telescopic rod 705, and the adjusting frame 707 is fixedly connected to the outside of the auxiliary lifting plate 706.

[0022] The auxiliary pit digging assembly 8 includes a connecting arm 801, an auxiliary frame 802, an arc-shaped water tank 803, a soil-dividing blade 804, a water inlet pipe 805 and a drainage hole 806. The connecting arm 801 is rotatably connected to the middle part of the adjusting frame 707, the auxiliary frame 802 is rotatably connected to the side of the connecting arm 801 away from the adjusting frame 707, the arc-shaped water tank 803 is fixedly connected to the outside of the auxiliary frame 802, the soil-dividing blade 804 is fixedly connected to the side of the arc-shaped water tank 803 away from the auxiliary frame 802, the water inlet pipe 805 is fixedly connected to the top of the arc-shaped water tank 803, and the drainage hole 806 is opened on the outside of the arc-shaped water tank 803.

[0023] The telescopic end of the electric telescopic rod 705 passes through the top of the fixed disc 704 and extends to the bottom of the fixed disc 704 and is fixedly connected to the top of the auxiliary lifting disc 706. A circular groove is opened in the middle of the fixed disc 704, and the fixed disc 704 is slidably connected to the outer wall of the driving shaft 701 through the circular groove.

[0024] A pressure valve is provided at the drainage hole 806 on the outer wall of the arc-shaped water tank 803 . The arc-shaped water tank 803 is filled with water. The bottom of the arc-shaped water tank 803 is rotatably connected to the middle of the positioning rotating frame 703 .

[0025] When it is necessary to dig a hole for planting trees, the device is moved to a designated position, and then the hydraulic lifting rod 2 is controlled to work, so that the digging drill bit 702 can contact the soil, and the drive motor 5 is turned on. When working, the drive motor 5 controls the rotating disc 601 and the digging drill bit 702 to rotate and dig a hole in the soil. Then, the hydraulic lifting rod 2 is controlled to continue to descend, so that the digging drill bit 702 provides an auxiliary downward force when digging a hole, and no tilting occurs when digging a hole.

[0026] As the digging work proceeds, when it is necessary to dig a pit that is wide at the top and narrow at the bottom, the driving motor 5 controls the digging drill bit 702 to rotate. At this time, the electric telescopic rod 705 is controlled to work. When the electric telescopic rod 705 is working, the electric telescopic rod 705 pushes the auxiliary lifting plate 706, and then the adjustment frame 707 on the auxiliary lifting plate 706 synchronously pushes the connecting arm 801. When the connecting arm 801 is under force, the auxiliary frame 802 is squeezed, so that the auxiliary frame 802 pushes the arc water tank 803. At this time, the soil-dividing blades 804 on the arc water tank 803 are tilted to dig the soil, which can expand the diameter of the upper side when digging the pit.

[0027] As the digging work proceeds, the driving motor 5 controls the digging drill bit 702 to rotate. When the digging drill bit 702 rotates, the arc-shaped water tank 803 rotates accordingly, generating centrifugal force during rotation. At this time, water is poured into the arc-shaped water tank 803 through the water inlet pipe 805 in advance. As the arc-shaped water tank 803 rotates, the water in the arc-shaped water tank 803 directly leaks out through the pressure valve in the drainage hole 806, and can come into contact with the soil, thereby reducing the density of the soil and making digging more labor-saving.

[0028] When the driving motor 5 controls the rotating disk 601 to rotate, centrifugal force is generated in the rotating disk 601, and the centrifugal force stretches the spring 602. At the same time, the spring 602 pushes the sliding plate 603, so that the slider on the sliding plate 603 slides in the sliding groove in the rotating disk 601. At the same time, the sliding plate 603 pushes the moving column 604 and the bulldozer 605, so that the bulldozer 605 can push the soil on the upper side of the pit to the outside when digging the pit, so as to prevent the soil from accumulating and re-entering the pit.
