[0016] Embodiment 1:

[0017] As Figures 1-5 shown, the precise alignment hole fertilization device based on electric drive control disclosed by the present utility model includes: a fertilizer spreading disc housing 1, a rotary drive mechanism, a fertilizer taking and bullet feeding mechanism, and a spiral fertilizer feeding mechanism; the spiral fertilizer feeding mechanism is installed at the lower part of the fertilizer spreading disc housing 1 for conveying fertilizer into the fertilizer spreading disc housing 1; a fertilizer discharging pipe 4 is communicated and arranged on the fertilizer spreading disc housing 1; the rotary drive mechanism is installed on the fertilizer spreading disc housing 1, the fertilizer taking and bullet feeding mechanism is installed on the rotary drive mechanism, the rotary drive mechanism drives the fertilizer taking and bullet feeding mechanism to rotate, and the fertilizer taking and bullet feeding mechanism scrapes fertilizer from the spiral fertilizer feeding mechanism and bullets it into the fertilizer discharging pipe 4.

[0018] The fertilizer taking and bullet feeding mechanism can relatively concentrate the scraped fertilizer per hole and then bullet it into the fertilizer discharging pipe 4, so that the fertilizer per hole is discharged relatively concentrated, ensuring that the fertilizer per hole is relatively concentrated, facilitating correspondence with the seed hole position, and ensuring the fertilization effect.

[0019] Furthermore, the rotary drive mechanism includes a fertilizer feeding drive motor 21, a central main shaft 5, and four branch mounting square pipes 6; the spiral fertilizer feeding mechanism includes a spiral drive motor 18, a spiral conveyor 17, and a fertilizer tank connecting pipe 20; the central main shaft 5 is rotatably installed at the central axis of the fertilizer spreading disc housing 1, and the fertilizer feeding drive motor 21 is used to drive the central main shaft 5 to rotate; the four branch mounting square pipes 6 are fixedly installed on the central main shaft 5 in a cross shape, and the fertilizer taking and bullet feeding mechanism is installed on the four branch mounting square pipes 6; a fertilizer inlet 14 is arranged at the lower part of the fertilizer spreading disc housing 1, the outlet of the spiral conveyor 17 is butt-joint installed at the fertilizer inlet 14, and the spiral drive motor 18 is used to drive the spiral conveyor 17; an inlet connecting pipe 19 is communicated and arranged at the inlet of the spiral conveyor 17; one end of the fertilizer tank connecting pipe 20 is connected to the inlet connecting pipe 19, and the other end is used to be connected to a fertilizer storage tank. The spiral fertilizer feeding mechanism can realize the stable feeding of fertilizer in a fixed quantity and at a fixed speed into the fertilizer feeding drive motor 21, thereby ensuring that the amount of fertilizer discharged each time is basically the same; using the four branch mounting square pipes 6 to install four bullet feeding units can effectively improve the fertilization efficiency.

[0020] Further, the fertilizer bullet feeding mechanism includes four bullet feeding units. Each bullet feeding unit includes a supporting compression spring 8 and a fertilizer feeding hopper 7. The supporting compression springs 8 of the four bullet feeding units are respectively fixedly installed in four branch mounting square tubes 6. One ends of the fertilizer feeding hoppers 7 of the four bullet feeding units are respectively slidably installed in the four branch mounting square tubes 6 and are elastically supported on the supporting compression springs 8. The other end of the fertilizer feeding hopper 7 is formed into a U-shaped fertilizer shovel by enclosing three side plates, which is used to extend out of the branch mounting square tube 6 to shovel the fertilizer conveyed at the fertilizer inlet 14. Circular grooves 3 are provided on the inner walls of the two side discs of the fertilizer spreading disc housing 1. The corresponding side outer walls of the branch mounting square tubes 6 are embedded in the circular grooves 3. The corresponding side outer walls of the U-shaped fertilizer shovels of the fertilizer feeding hoppers 7 are close to the inner walls of the two side discs of the fertilizer spreading disc housing 1. A fertilizer discharging port 15 is provided on the side edge of the fertilizer spreading disc housing 1, and when the branch mounting square tube 6 rotates to the fertilizer discharging port 15, it is in a horizontal state. The upper end of the fertilizer discharging pipe 4 is connected to the fertilizer discharging port 15. A lifting platform 2 is provided on the circumferential inner wall of the fertilizer spreading disc housing 1 and above the fertilizer discharging port 15, and the lifting surface of the lifting platform 2 gradually rises from the top of the circumferential inner wall of the fertilizer spreading disc housing 1 to the fertilizer discharging port 15 to reach the maximum. The supporting compression spring 8 can elastically push the fertilizer feeding hopper 7, so that the fertilizer feeding hopper 7 is ejected after leaving the lifting platform 2. Under the action of inertia, the stored fertilizer inside is ejected and thrown into the fertilizer discharging pipe 4 at one time, making the discharged fertilizer relatively concentrated. By rotating and installing the four bullet feeding units, after the U-shaped fertilizer shovels of the fertilizer feeding hoppers 7 obtain fertilizer from the fertilizer inlet 14, they slide into the fertilizer feeding hoppers 7 during the rotating upward process and gather at the bottom of the fertilizer feeding hoppers 7, which is convenient for ejecting and throwing at one time as a whole. The circular grooves 3 can facilitate the embedding of the side walls of the branch mounting square tubes 6, avoid too large a gap between the side of the fertilizer feeding hopper 7 and the inner wall of the fertilizer spreading disc housing 1, and prevent fertilizer from leaking from the gap. The lifting platform 2 can gradually push and press the U-shaped fertilizer shovels of the fertilizer feeding hoppers 7 to compress the supporting compression spring 8, so that when the U-shaped fertilizer shovels leave the lifting platform 2, the fertilizer feeding hoppers 7 have the maximum extension acceleration and eject and throw the stored fertilizer inside at one time as a whole.

[0021] Further, a telescopic guiding sliding groove 12 is provided on the inner wall of the branch mounting square tube 6, and a telescopic guiding sliding block 13 that is slidably embedded in the telescopic guiding sliding groove 12 is provided on the outer wall of the fertilizer feeding hopper 7. When the telescopic guiding sliding block 13 moves to the outer end of the telescopic guiding sliding groove 12, the end of the U-shaped fertilizer shovel is close to the circumferential inner wall of the fertilizer spreading disc housing 1. By the cooperation of the telescopic guiding sliding groove 12 and the telescopic guiding sliding block 13, the movement limit of the fertilizer feeding hopper 7 can be realized, and the fertilizer feeding hopper 7 can be prevented from being completely ejected out of the branch mounting square tube 6 and falling into the fertilizer discharging pipe 4.

[0022] Further, the end face of the lifting platform 2 at the fertilizer discharging port 15 is a horizontal plane, so that the fertilizer feeding hopper 7 will not be blocked when it pops out, ensuring the popping speed; an arc chamfer 11 is provided at the end edge of the U-shaped fertilizer bucket of the fertilizer feeding hopper 7, which is matched with the lifting surface of the lifting platform 2, and the side plate edges of the U-shaped fertilizer bucket close to the inner walls of the two side discs of the fertilizer spreading disc housing 1 are provided as fertilizer shoveling inclined planes 16. The arc chamfer 11 can enable a smooth transition when the U-shaped fertilizer bucket contacts the lifting platform 2; the fertilizer shoveling inclined plane 16 can quickly collect the fertilizer into the U-shaped fertilizer bucket when shoveling the fertilizer from the fertilizer inlet 14.

[0023] Further, an arc-shaped lifting slope 10 is provided on the inner wall of the hopper side plate 9 of the fertilizer feeding hopper 7 that is not used to enclose the U-shaped fertilizer bucket, and the arc-shaped lifting slope 10 gradually rises from the inner end to the outer end of the fertilizer feeding hopper 7. The arc-shaped lifting slope 10 can make the fertilizer always concentrate at the bottom of the fertilizer feeding hopper 7 when the fertilizer feeding hopper 7 rotates and rises and rotates to the lifting platform 2, and can provide an obliquely upward guiding direction for the fertilizer when ejecting the fertilizer, avoiding the fertilizer from flying and falling outside the fertilizer discharging port 15.

[0024] When the precision alignment hole fertilization device based on electric drive control disclosed by the utility model is installed and used, the fertilizer feeding drive motor 21 and the spiral drive motor 18 are electrically connected to the controller of the seeder, or a control cabinet is separately provided for driving and controlling the fertilizer feeding drive motor 21 and the spiral drive motor 18, so as to realize synchronous control with the seeder of the seeder and correspond the fertilizer discharging and seeding positions; then the fertilizer tank connecting pipe 20 is connected to the fertilizer storage tank.

[0025] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present invention itself. Various changes can be made in its form and details without departing from the spirit and scope of the present invention defined by the appended claims.
