[0024] Among them, it also includes an armrest 19, which is fixed on the side bracket of the support plate. The armrest 19 is provided with a power switch group 13, and the power switch group 13 is equipped with a power supply 20. The power supply 20 and the stepper motor 14 are electrically connected to the power switch group 13. The base 1 is moved to the fertilizing area through the moving wheel 2. The armrest 19 is used to allow the user to perform manual operation. The barrel 17 is used to hold the fertilizer material. The output shaft of the stepper motor 14 drives the connecting shaft 15 to rotate, and the connecting shaft 15 drives the stirring rod 16 and the auger 10 to rotate. The stirring rod 16 stirs the material in the barrel 17 to avoid material agglomeration and causing difficulty in transportation. The auger 10 transports the material to the feeding pipe 9. The material in the feeding pipe 9 enters the drill bit 7 through the bellows 11 under the action of gravity. The material in the drill bit 7 is discharged into the pit through the discharge hole 6. The fertilization operation can be carried out without the drill bit 7 completely exiting the pit, thereby further improving the efficiency of fertilization.

[0025] The lifting mechanism 4 includes a guide rod 42 and a lifting seat 44. The guide rod 42 is fixed between the support plate and the base 1. The lifting seat 44 is connected to the guide rod 42 for sliding up and down. The mounting seat 5 is fixed to the side of the lifting seat 44. The lifting mechanism 4 also includes an electric push rod 43. The electric push rod 43 is installed on the top of the support plate.

The telescopic end of the electric push rod 43 drives the lifting seat 44 to perform lifting and lowering movements. The lifting seat 44 slides up and down along the guide rod 42, so that the scale 41 on the guide rod 42 is read to determine the depth of the pit. Since the fertilization depth of the trees is different in different growth periods, the depth of the pit is determined to meet the fertilization requirements, thereby ensuring the quality of fertilization.

[0026] The driving mechanism 3 includes a servo motor 31, a worm 32 and a worm wheel 33. The worm 32 is rotatably mounted on the top stand of the mounting seat 5. The servo motor 31 is mounted on the side of the stand. The output shaft of the servo motor 31 is fixedly connected to the end of the worm 32.

The lifting seat 44 drives the mounting seat 5 to move up and down, thereby adjusting the drilling depth of the drill bit 7. The output shaft of the servo motor 31 drives the worm 32 to rotate, and the worm 32 is engaged with the worm wheel 33. The worm wheel 33 drives the drill bit 7 to rotate, thereby completing the digging operation.

[0027] The support unit 8 includes a connecting seat 81 and a telescopic rod 82. The telescopic rod 82 is fixed to the bottom of the support plate, and the connecting seat 81 is fixed to the telescopic end of the telescopic rod 82. The drill rod of the drill bit 7 is rotatably connected to the connecting seat 81 through a rotary joint 12. One end of the bellows 11 is fixed on the connecting seat 81 and is connected to the inside of the drill rod of the drill bit 7. During the lifting process of the drill bit 7, the connecting seat 81 drives the telescopic rod 82 to perform telescopic movement, and the drill bit 7 rotates relative to the connecting seat 81 through the rotary joint 12.

[0028] The working principle of the fertilizing device for forestry tree planting provided by the utility model is as follows: the base 1 is moved to the fertilizing area by the moving wheels 2, the handrail 19 is used for the user to operate by hand, the barrel 17 is used to hold the fertilizer material, the telescopic end of the electric push rod 43 drives the lifting seat 44 to move up and down, and the lifting seat 44 slides up and down along the guide rod 42, so that the scale 41 on the guide rod 42 reads the number, thereby determining the depth of the pit. Since the fertilization depth of the trees is different at different growth stages, the pit depth is determined to meet the fertilization needs;

[0029] The lifting seat 44 drives the mounting seat 5 to perform lifting and lowering motion, thereby adjusting the drilling depth of the drill bit 7. The output shaft of the servo motor 31 drives the worm 32 to rotate, and the worm 32 engages with the worm gear 33. The worm gear 33 drives the drill bit 7 to rotate, thereby completing the digging operation. During the lifting process of the drill bit 7, the connecting seat 81 drives the telescopic rod 82 to perform telescopic motion. The drill bit 7 rotates relative to the connecting seat 81 through the rotary joint 12.

[0030] The output shaft of the stepper motor 14 drives the connecting shaft 15 to rotate, and the connecting shaft 15 drives the stirring rod 16 and the auger 10 to rotate. The stirring rod 16 stirs the material in the barrel 17 to prevent the material from agglomerating and causing difficulty in transportation. The auger 10 transports the material to the feed pipe 9. The material in the feed pipe 9 enters the drill bit 7 through the bellows 11 under the action of gravity. The material in the drill bit 7 is discharged into the pit through the discharge hole 6. Fertilization operations can be carried out without the drill bit 7 completely withdrawing from the pit. The covering plate is used to fill the pit.
