A protective cover 62 is sleeved on the surface of the cross bar 61. By setting the cross bar 61 and the protective cover 62, the device can be pushed better.

[0038] As can be seen from the above, by setting the first servo motor 19 to rotate in coordination, it is convenient to drive the soil improvement and repair agent inside the repair agent box 11 for transportation, and transport the soil improvement and repair agent to the inside of the discharge tray 3. At the same time, the discharge tray 3 is coordinated with the repair agent pipe 14 and the first flow valve 16 set in the bottom array, which can play the role of discharging the soil improvement and repair agent through the repair agent pipe 14 and controlling the discharging amount of the repair mechanism 1 through the first flow valve 16, thereby increasing the accuracy of the repair mechanism 1, and adopting the fertilizer tray 41 to cooperate with the fertilizer pipe 43 set in the bottom array and the second flow valve 45 set on the outer wall of the fertilizer pipe 43, which can play the role of discharging the fertilizer tray The fertilizer inside 41 is transported to the inside of the repair agent tube 14 through the fertilizer pipe 43, and the flow is controlled by the second flow valve 45, thereby realizing precision fertilization and soil repair. At the same time, the vibrator 48 is used in conjunction with the positioning plate 44 to drive the discharge tray 3 and the fertilizer tray 41 to vibrate, which can increase the discharge effect of the discharge tray 3 and the fertilizer tray 41.

[0039] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a stratification mechanism 7 is provided on the outside of the repair mechanism 1, and the stratification mechanism 7 includes an improved fertilizer pipe 71, and the improved fertilizer pipe 71 is connected to the repair agent pipe 14, and an opening head 72 is sleeved on the bottom of the improved fertilizer pipe 71. The bottom of the opening head 72 is conical, and a plurality of blocking plates 78 are provided on the surface of the opening head 72. A plurality of discharge holes 79 are opened between the plurality of blocking plates 78, and a plurality of push rods 74 are provided on the top of the opening head 72. A push plate 73 is slidably sleeved on the surface of the push rod 74, and the push plate 73 is fixedly connected to the outside of the improved fertilizer pipe 71, and a plurality of springs 77 are provided on the top of each spring 77. A movable sleeve 75 is provided on the top of the push rod 74, and the push rod 74 is located inside the spring 77, and the top is fixedly connected to the movable sleeve 75. A limiting block 76 is provided on the top of the improved fertilizer pipe 71.

[0040] As can be seen from the above, by pressing the movable sleeve 75 downward, the movable sleeve 75 squeezes the spring 77, so that the spring 77 drives the push plate 73 and the push rod 74 to move. When the push rod 74 and the push plate 73 move, they will drive the opening head 72 to move, so that the opening head 72 opens holes around the fruit trees, and stratifies the openings under the action of the blocking plate 78. At this time, the first flow valve 16 is opened to discharge the mixed fertilizer and soil improvement and repair agent from the discharge port, thereby fertilizing and improving the soil around the fruit trees. After fertilization is completed, the movable sleeve 75 rebounds under the action of the spring 77, so that the opening head 72 is separated from the ground, and then the ground opening is buried, so that the device can complete soil improvement and repair while fertilizing.

[0041] Working principle: First, take out the device and place it in an appropriate position. Then, fill the repair agent box 11 inside the device with an appropriate amount of soil improvement and repair agent, and fill the fertilizer disc 41 with an appropriate amount of fertilizer. Then, install the dispersion mechanism 5, and then push the device.

[0042] When fertilization and repair mechanism 1 need to be operated, first start the servo motor installed at the bottom of the repair agent box 11, and the servo motor drives the spiral shaft arranged inside the repair agent box 11 to rotate, thereby driving the soil improvement and repair agent to rise and transport it to the inside of the discharge tray 3, and then the second servo motor 52 drives the rotating block 54 and the rotating ring 53 to rotate, so that the dispersion plate 56 at the bottom of the rotating ring 53 rotates, and the soil improvement and repair agent inside the discharge trough 12 is evenly dispersed. At this time, the vibrator 48 symmetrically arranged on both sides of the discharge tray 3 is started, and the vibrator 48 drives the discharge tray 3 and the fertilizer tray 41 to vibrate, so that the soil improvement and repair agent inside the discharge tray 3 is transported to the inside of the repair agent pipe 14 through the discharge hole 13. At the same time, the fertilizer tray 41 is transported to the inside of the fertilizer pipe 43 through the material hole opened on its top, and the amount of fertilizer is controlled by the second flow valve 45 arranged on the outer wall of the fertilizer pipe 43;

[0043] At this time, the first flow valve 16 is started, and the soil improvement and repair agent inside the repair agent tube 14 is quantitatively transported. At this time, the fertilizer is transported to the inside of the repair agent tube 14 through the fertilizer pipe 43 and mixed with the soil improvement and repair agent. After the body is transported to the appropriate position, the movable sleeve 75 is pressed downward to squeeze the spring 77, so that the spring 77 drives the push plate 73 and the push rod 74 to move. When the push rod 74 and the push plate 73 move, they will drive the opening head 72 to move, so that the opening head 72 opens holes around the fruit trees, and the openings are layered under the action of the blocking plate 78. At this time, the first flow valve 16 is opened to discharge the mixed fertilizer and soil improvement and repair agent from the discharge port, thereby fertilizing and improving the soil around the fruit trees. After fertilization is completed, the movable sleeve 75 rebounds under the action of the spring 77, so that the opening head 72 is separated from the ground, and then the ground opening is buried, so that the device can complete soil improvement and repair while fertilizing.
