[0002] Fertilization is an important means of providing nutrients required by crops in agricultural production. Through fertilization, nutrients in the soil can be supplemented to meet the nutritional needs of crops during growth, promote the healthy growth of crops, and improve the yield and quality of crops. Currently, the commonly used fertilization methods include line fertilization, hole fertilization, ring fertilization, etc. Taking hole fertilization as an example, most of the fertilization process is done manually by digging holes.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] For example, see Figure 1-9 The present invention provides a method for precise fertilization at a fixed point in agricultural planting, which is specifically as follows: when in use, after the fertilizer is added into the storage box 21 through the feeding port, the servo motor 25 in the storage box 21 is started, so that the servo motor 25 drives the stirring rod 23 to rotate, and the multiple beating plates 24 on the stirring rod 23 continuously beat the fertilizer under the rotation of the stirring rod 23 to break up the clumped fertilizer, and the whole device is moved to the position where fertilization is required and fixed by the mobile vehicle 1; The plurality of electric push rods 13 are started, so that the plurality of electric push rods 13 drive the synchronous plate 14 to move downward, thereby driving the fertilizer barrel 31 to move downward, so that the bottom of the fertilizer barrel 31 contacts the ground, and at the same time, the second synchronous gear 65 gradually meshes with the limit rack 52 and rotates under the action of the limit rack 52, and the first synchronous gear 64 rotates synchronously driven by the second synchronous gear 65, and the two synchronous racks 63 meshing with the second synchronous gear 65 slide in a direction close to each other, so that the two blocking plates 61 gradually separate from the isolation plate 61. The fertilizing cylinder 31 is closed, the hydraulic push rod 15 and the driving motor 36 are started, so that the driving motor 36 drives the auger 33 to rotate, and at the same time, the hydraulic push rod 15 pushes the connecting plate 35 to move downward along the inner wall of the isolation cylinder 32, so that the auger 33 moves downward to drill a hole. When the drilling depth reaches a predetermined depth, the driving motor 36 is turned off, and the hydraulic push rod 15 is driven to drive the connecting plate 35 and the auger 33 to move upward to reset. When the auger 33 moves upward, the soil produced by the drilling is brought into the isolation cylinder 32 for temporary storage. After the isolation cylinder 32 completes drilling, the electric push rod 13 is started, so that the electric push rod 13 drives the fertilization cylinder 31 to move slightly upward, and the second synchronous gear 65 rotates in the opposite direction under the action of the limit rack 52, so that the first synchronous gear 64 drives the two synchronous racks 63 to move in the direction away from each other, so that the two blocking plates 61 are opened, and the fertilizer falls on the feed tray 38. When the first synchronous gear 64 rotates, it also drives the second bevel gear 66 to rotate, and drives the first bevel gear 37 to rotate through the second bevel gear 66, so that the first bevel gear 37 drives the feed tray 38 to rotate, so that the fertilizer falls evenly into the drilled fertilization hole through the feed port 39. When the fertilizer is added, the drive motor 36 is started again, so that the drive motor 36 drives the auger 33 to reverse, so that the soil on the auger 33 falls into the borehole again, and the borehole is backfilled.

After fixing, the multiple electric push rods 13 are first started, so that the multiple electric push rods 13 drive the synchronous plate 14 to move downward, thereby driving the fertilization component 3 to move downward, so that the bottom of the fertilization component 3 contacts the ground; When the fertilization component 3 is completely in contact with the ground, the electric push rod 13 is turned off and the hydraulic push rod 15 is started, so that the hydraulic push rod 15 drives the drilling component to drill a fertilization hole downward. After drilling the hole, the hydraulic push rod 15 drives the drilling component to reset and stores the drilled soil in the fertilization component 3. At this time, the fertilization component 3 performs fertilization. After the fertilization is completed, the drilling component pours the soil stored in the fertilization component 3 back into the drilled fertilization hole to backfill the fertilization hole; By setting up the drilling fertilization method, the accuracy of fertilization and the utilization rate of fertilizer can be greatly increased, and fertilizer waste can be reduced.

[0021] For example 3, please refer to Figure 2 , Figure 3 and Figure 7 The fertilization assembly 3 includes a fertilization barrel 31, a limiting groove is provided on the surface of the fertilization barrel 31 near the bottom end, and the adjustment assembly 6 is slidably connected to the limiting groove. The inner wall of the fertilization barrel 31 and the outer wall of the drilling assembly form a fertilization chamber 34. The bottom of the fertilization barrel 31 is also rotatably connected to a feed tray 38, and a feed port 39 is provided on the feed tray 38. The top of the feed tray 38 is an inclined surface, and the inclined direction of the inclined surface is toward the feed port 39. The outer surface of 31 is also rotatably connected to a first bevel gear 37 fixed to the feed tray 38. The drilling assembly is arranged inside the fertilization barrel 31. The drilling assembly includes an isolation barrel 32, and an auger 33 is arranged inside the isolation barrel 32. Two connecting plates 35 are slidably connected to the top of the isolation barrel 32. A driving motor 36 is installed between the two connecting plates 35. The output end of the driving motor 36 is fixed to the top of the auger 33 through a coupling, and the connecting plate 35 near the top is fixed to the hydraulic push rod 15 on the L-shaped fixing plate 12. When fertilizing, when the synchronous plate 14 moves downward, the fertilizer cylinder 31 is driven to move downward at the same time, so that the bottom of the fertilizer cylinder 31 and the auger 33 touch the ground, the hydraulic push rod 15 and the drive motor 36 are started, so that the drive motor 36 drives the auger 33 to rotate, and at the same time, the hydraulic push rod 15 pushes the connecting plate 35 to move downward along the inner wall of the isolation cylinder 32, so that the auger 33 moves downward to drill a hole. When the drilling depth reaches a predetermined depth, the drive motor 36 is turned off, and the hydraulic push rod 15 is driven to drive the connecting plate 35 and the auger 33 to move upward to reset. When the auger 33 moves upward, the soil produced by the drilling is brought into the isolation cylinder 32 for temporary storage. When the fertilizer is added, the drive motor 36 is started again, so that the drive motor 36 drives the auger 33 to reverse, so that the soil on the auger 33 falls back into the borehole to backfill the borehole. By providing a drive motor 36 to drive the auger 33 to reverse, the soil produced by the drilling is refilled into the hole, thereby realizing automatic backfilling, greatly reducing manual labor, greatly increasing work efficiency, and helping to quickly restore the soil surface.

[0022] Example 4, please refer to Figure 2-7 The adjusting assembly 6 includes two baffle plates 61, which are respectively slidably connected to the fertilizer cylinder 31, and the inner diameter of the two baffle plates 61 is the same as the diameter of the isolation cylinder 32. A connecting block 62 is installed at one end of the two baffle plates 61, and the two connecting blocks 62 are fixedly connected to a synchronous rack 63 on the side away from the baffle plates 61. The adjusting assembly 6 also includes a first synchronous gear 64, which is arranged between the two synchronous racks 63, and the first synchronous gear 64 is respectively meshed with the two synchronous racks 63. The first synchronous gear 64 is fixedly connected to a connecting shaft on the side close to the fertilizer cylinder 31. The adjusting assembly 6 also includes The second bevel gear 66 is included, and the second bevel gear 66 is installed on the connecting shaft. The second bevel gear 66 is meshed with the first bevel gear 37. A connecting rod is provided at one end of the second bevel gear 66 close to the fertilizer barrel 31, and the connecting rod is fixedly rotated on the fertilizer barrel 31. An adjusting plate 5 is also installed at the bottom of the mobile vehicle 1, and a sliding cavity 51 is provided on the adjusting plate 5. A synchronous shaft is installed on one side of the first synchronous gear 64 close to the sliding cavity 51, and the synchronous shaft is slidably connected to the sliding cavity 51. A second synchronous gear 65 is also installed at the other end of the synchronous shaft, and a limit rack 52 meshing with the second synchronous gear 65 is installed on the other side of the adjusting plate 5; In the initial position, the first synchronous gear 64 and the synchronous shaft are located at a high position on the sliding cavity 51, and the two blocking plates 61 are not in contact with the isolation cylinder 32. When the synchronous plate 14 drives the fertilizer cylinder 31 to move downward, the fertilizer cylinder 31 simultaneously drives the synchronous shaft and the first synchronous gear 64 to move downward. When the second synchronous gear 65 at the other end of the first synchronous gear 64 moves downward, it gradually contacts the limit rack 52 and rotates under the action of the limit rack 52. The first synchronous gear 64 rotates synchronously driven by the second synchronous gear 65, and the two synchronous racks 63 meshing with the second synchronous gear 65 slide in a direction approaching each other, so that the two blocking plates 61 gradually contact the isolation cylinder 32, and the fertilizer cylinder 31 is closed. When the fertilizer cylinder 31 is closed, the fertilizer in the storage assembly 2 enters the fertilizer cavity 34 formed between the fertilizer cylinder 31 and the isolation cylinder 32, and is ready for fertilization; After the isolation cylinder 32 has completed drilling, the electric push rod 13 is started, so that the electric push rod 13 drives the fertilizer cylinder 31 to move slightly upward, and the second synchronous gear 65 rotates in the opposite direction under the action of the limit rack 52, so that the first synchronous gear 64 drives the two synchronous racks 63 to move in the direction away from each other, so that the two blocking plates 61 are opened, and the fertilizer falls on the feed tray 38. When the first synchronous gear 64 rotates, it drives the second bevel gear 66 to rotate at the same time, and drives the first bevel gear 37 to rotate through the second bevel gear 66, so that the first bevel gear 37 drives the feed tray 38 to rotate, so that the fertilizer falls evenly into the drilled fertilizer hole through the feed port 39; When fertilizing again, the fertilizing tube 31 moves downward to drive the two blocking plates 61 to close the bottom of the fertilizing tube 31 again, so that the fertilizer falls into the fertilizing chamber 34 for fertilization.

[0023] For example 5, please refer to Figure 2 , Figure 8 and Fig. 9 The material storage assembly 2 includes a material storage box 21, a feeding port is provided on the top of the material storage box 21, a material discharge port is provided at the bottom of the material storage box 21, a material delivery hose 4 is connected to the material discharge port, and the other end of the material delivery hose 4 is connected to the fertilization chamber 34 in the fertilization barrel 31, and a stirring rod 23 is rotatably connected in the inner wall of the material storage box 21, and a plurality of evenly distributed beating plates 24 are installed on the stirring rod 23, and a servo motor 25 is also installed in the inner wall of one side of the material storage box 21, and the output end of the servo motor 25 is fixed to one end of the stirring rod 23 through a coupling, and a first synchronous wheel 26 is also installed on the coupling, and a discharge wheel 22 is rotatably connected in the material discharge port of the material storage box 21, and one end of the discharge wheel 22 is fixedly connected to the second synchronous wheel 27, and a transmission belt 28 is sleeved between the first synchronous wheel 26 and the second synchronous wheel 27, and the first synchronous wheel 26 and the second synchronous wheel 27 are connected by the transmission belt 28; When in use, after the fertilizer is added into the storage box 21 through the feeding port, the servo motor 25 in the storage box 21 is started, so that the servo motor 25 drives the stirring rod 23 to rotate, and the multiple beating plates 24 on the stirring rod 23 continuously beat the fertilizer under the rotation of the stirring rod 23, so as to break up the clumped fertilizer and prevent the fertilizer from accumulating in the storage box 21 and being unable to fall down; At the same time, when the stirring rod 23 rotates, the first synchronous wheel 26 and the transmission belt 28 simultaneously drive the second synchronous wheel 27 to rotate, so that the second synchronous wheel 27 drives the unloading wheel 22 to rotate, and the fertilizer in the storage box 21 is input into the fertilization chamber 34 through the feeding hose 4 for fertilization; By setting the unloading wheel 22, it can be ensured that the amount of fertilizer dropped each time is basically the same, and at the same time, it can be prevented that the fertilizer accumulates at the discharge port and causes blockage; When no fertilizer is applied, one end of the feed hose 4 located at the fertilizer barrel 31 is higher than one end of the storage box 21, so at this time the fertilizer cannot enter the fertilizer chamber 34 through the feed hose 4. When fertilization is needed, the fertilizer barrel 31 gradually moves downward. When the fertilizer barrel 31 is fully moved into place, one end of the feed hose 4 located at the storage box 21 is higher than one end of the fertilizer barrel 31. At this time, the fertilizer can smoothly enter the fertilizer chamber 34. When fertilization is completed, the stirring rod 23 and the discharge wheel 22 stop rotating, and the fertilizer cannot fall. At the same time, the fertilizer barrel 31 moves upward again to further ensure that the fertilizer cannot fall out.
