The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] When grapefruit is planted, pile driving is required. For this purpose, a grapefruit planting pit driving machine is provided. Figure 1 As shown, it includes a frame 1 for mounting devices;

[0024] The limiting sliding column 2 located inside the frame 1 is used for sliding limiting;

[0025] A sliding frame 4 located outside the limiting sliding column 2 and slidably connected thereto is used to adjust the height of the pile when planting grapefruit;

[0026] The mounting plate 9 located on one side of the sliding frame 4 is used to install the grapefruit planting piling device; a forward and reverse motor 8 is installed at the middle position of the top of the mounting plate 9 to provide power for piling, and a rotating column 10 is fixed to the output end of the forward and reverse motor 8, and a spiral plate 11 is fixed to the outside of the rotating column 10. The forward and reverse motor 8 drives the spiral plate 11 to rotate through the rotating column 10, and the sliding frame 4 is manually moved down to complete the piling. A stud 7 is fixed to one side of the mounting plate 9, and a nut 6 is connected to the outside of the stud 7 through a thread. The interior of the sliding frame 4 is provided with a mounting hole 5 that cooperates with the stud 7. The nut 6 is loosened to remove it from the stud 7, and then the stud 7 is taken out from the inside of the mounting hole 5, which is convenient for replacing accessories;

[0027] Please refer to Figure 1-3 A tension spring 3 is fixed at the middle position of the top of the sliding frame 4, which is used for the sliding frame 4 to reset upward, and racks 21 are fixed on both sides of the bottom of the sliding frame 4. Both ends of one side of the frame body 1 are rotatably connected to a rotating rod 20, and an inclined plate 22 is fixed to the end of the rotating rod 20.

The number of the inclined plates 22 is two groups, and the two groups of inclined plates 22 fit each other and cooperate with the spiral plate 11.

[0028] It can be understood that when the sliding frame 4 moves down to a certain extent, the rack 21 and the gear 19 fit each other, and at this time, the two sets of inclined plates 22 are closed to each other and located on the outside of the spiral plate 11. When piling, the soil is located on the top of the inclined plate 22. When the piling is completed, the forward and reverse motor 8 is reversed. At this time, the sliding frame 4 is manually pulled upward. At this time, the gear 19 and the rack 21 cooperate with each other, and the gear 19 drives the rotating rod 20 to reverse, and the inclined plates 22 reverse to both sides, and the soil is poured outward to prevent it from entering the inside of the piling hole;

[0029] Please refer to Figure 1 and 2 , an auxiliary rod 14 is provided on one side of the frame 1, and a marking rod 12 is slidably connected inside the auxiliary rod 14, and a fastening rod 17 is rotatably connected to the top of the end of the marking rod 12 through a thread, a rotating knob 16 is fixed to the top of the fastening rod 17, a moving groove 18 is provided on the top of the auxiliary rod 14, and a scale 15 is provided on the surface of the auxiliary rod 14, the cross section of the marking rod 12 is a U-shaped structure, a roller 13 is provided at the bottom end of one side of the frame 1, and a handle is provided at the top end of one side of the frame 1;

[0030] It should be understood that after loosening the rotating knob 16, pull the marking rod 12, and check the piling distance with the help of the scale 15, then turn the rotating knob 16 to drive the fastening rod 17 to rotate. Under the action of the thread, the fastening rod 17 gradually reduces the distance between the rotating knob 16 and the auxiliary rod 14, and generates friction to fix the rotating knob 16 and the auxiliary rod 14. Then, under the action of the roller 13, pull the frame 1 to move. When the marking rod 12 coincides with the edge of the pile hole that has been drilled, perform the next set of drilling, thereby facilitating the adjustment of the piling distance.
