[0002] Peanut seed sowing is a core and fundamental step in the process of breeding improved peanut varieties. It directly determines the population consistency and trait identification accuracy of breeding experiments. It is a key process connecting parent breeding, offspring trait screening and improved variety propagation. Unlike large-scale field planting, peanut seed sowing is aimed at precious breeding materials and has extremely high requirements for sowing precision, uniformity of field layout and controllability of the sowing environment. In the breeding process, the number of seeds is limited and their genetic value is high. The sowing process should minimize mechanical damage to the seeds, and with appropriate soil covering depth and seed-fertilizer isolation conditions, ensure uniform emergence and seedling rate, and avoid affecting the complete identification of breeding materials due to incomplete emergence.

[0020] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0021] Example: Refer to Figure 1-13An automatic peanut breeding and precision sowing device includes a frame 1, with support frames 2 fixed on the left and right sides of the bottom of the frame 1, and a fixed box 4 between the two support frames 2. A lifting frame 3 is movably connected to the top of the support frames 2, and an electric push rod is vertically installed on the top of the support frames 2. The push rod end of the electric push rod is fixed to the bottom of the lifting frame 3 to provide lifting power for the lifting frame 3. The sowing depth is adjusted by the vertical displacement of the lifting frame 3. A protective shell 301 is fixed on the upper surface of the frame 1. The protective shell 301 covers the outside of the lifting frame 3 along the movement direction of the lifting frame 3, so that the lifting frame 3 is shielded at any height to prevent mud and water from entering. A first fixed frame 16 and multiple limiting rods are fixed across the two lifting frames 3. 17. A second fixed frame 19 that can slide along the rod is fitted on the limiting rod 17. A lead screw 18 is inserted through the side wall of the lifting frame 3. The lead screw 18 is threadedly engaged with the second fixed frame 19 to drive the second fixed frame 19 to move along the limiting rod 17. Both the first fixed frame 16 and the second fixed frame 19 are equipped with a sowing component 20. A storage box 5 is also fixed on the frame 1. The storage box 5 contains a storage bucket 6. The bottom of the storage bucket 6 is connected to the sowing component 20 for sowing. A fertilizer hopper 8 is sandwiched between the storage box 5 and the frame 1. The bottom of the fertilizer hopper 8 is connected to a fertilizer transport pipe 11. A guide rail frame 21 is fixed at the front of the frame 1. A movable block 24 is embedded in the guide rail frame 21. A soil scraper 28 is suspended below the movable block 24.

[0022] The first fixed frame 16 is horizontally positioned between the two lifting frames 3 and near the front of the vehicle, while the limiting rod 17 is horizontally positioned between the two lifting frames 3 and near the rear of the vehicle. The two frames stand separately to form the installation reference for the sowing component 20. Both the first fixed frame 16 and the second fixed frame 19 have mounting grooves that are adapted to the shape of the sowing component 20. The sowing component 20 is embedded and fixed in the mounting grooves. The sowing component 20 adopts a roller-type sowing structure. The inner cavity of the lifting frame 3 is equipped with a drive motor, and the output shaft of the drive motor is coaxial with one end of the lead screw 18. The torque is converted into linear displacement of the second fixed frame 19 by the rotation of the lead screw 18. There are two second fixed frames 19, both of which are mounted on the limiting rod 17 and can slide along the rod. Each of the two lifting frames 3 supports a lead screw 18, and each of the two lead screws 18 passes through a second fixed frame 19 and is threaded to it, so that the spacing between the two second fixed frames 19 can be adjusted independently. Each second fixed frame 19 is equipped with a sowing component 20, thereby realizing multi-row sowing with adjustable row width.

[0023] The storage box 5 is supported and fixed by the fixed box 4 and the frame 1. The storage box 5 is equipped with multiple storage barrels 6. Each storage barrel 6 is connected to a discharge pipe 7 at the bottom. The top of the sowing component 20 is equipped with a small funnel. The top of the small funnel is covered with a top cover. The discharge pipe 7 adopts a telescopic corrugated pipe structure. Its lower end passes through the top cover and extends into the small funnel and communicates with it. It can adaptively extend and retract without detaching as the second fixed frame 19 moves.

[0024] A partition plate 10 extends downward from the bottom of the storage box 5. The partition plate 10 stands vertically between the sowing component 20 and the fertilizer hopper 8 to separate the sowing area and the fertilization area. A partition plate 9 is vertically fixed inside the fertilizer hopper 8, dividing the fertilizer hopper 8 into multiple independent fertilizer compartments 801 for storing different fertilizers. Each fertilizer compartment 801 has a discharge port 12 at its bottom, and a sealing arc plate 30 is installed at the discharge port 12. The sealing arc plate 30 is connected to an electric push rod installed inside the partition plate 10, and is pushed by the electric push rod. Pulling the pipe opens and closes the discharge port 12; the inner cavity of the fertilizer transport pipe 11 is equipped with transport blades 13, which, through the rotation of the transport blades 13, gather the fertilizer falling from each discharge port 12 to the middle of the pipe body. The bottom end of the fertilizer transport pipe 11 is connected to a mixing tank 14, and the bottom outlet of the mixing tank 14 is equipped with a control valve. The outlet of the control valve is connected to a fertilizer discharge pipe 15. The fertilizer discharge pipe 15 adopts a branch pipe structure, with multiple branch pipes branching from a main pipe. The bottom of each branch pipe has through holes, so that the fertilizer is evenly spread on the sowing area after being diverted.

[0025] The guide rail frame 21 has a limiting groove 22 opened laterally. A rack 23 is fixed to one side wall of the limiting groove 22. The movable block 24 is embedded in the limiting groove 22 and can slide along the groove. A small motor is installed inside the movable block 24. A gear 25 is fixed on the output shaft of the small motor. The gear 25 meshes with the rack 23. The gear 25 drives the movable block 24 to move horizontally within the limiting groove 22 by rolling along the rack 23. A fixed rod 29 is fixed laterally on the frame 1 below the partition plate 10. One end of the scraper frame 28 is sleeved on the fixed rod 29 and can slide along the rod. A connecting frame 27 is fixed to the bottom of block 24. The lower end of the connecting frame 27 clamps the same end of the scraper frame 28, so that the scraper frame 28 moves synchronously with the movable block 24. A drive frame 26 is also suspended at the bottom of the movable block 24 by a small push rod. The drive frame 26 and the scraper frame 28 are in a limited sliding fit. When the small push rod extends or retracts, the drive frame 26 moves the scraper frame 28 to swing around the fixed rod 29 to adjust the scraping depth. There are multiple movable blocks 24. The position of each movable block 24 corresponds to each sowing component 20 to ensure that the scraping coverage area is aligned with the sowing area.

[0026] In this invention, the frame 1 is the basic frame of an existing agricultural cart. A push rod is installed at the rear of the frame 1, allowing for both motor-driven and hand-push operation. Support frames 2 are fixed to both sides of the bottom of the frame 1, and a fixed box 4 is installed between the two support frames 2. The fixed box 4 is mainly used to store electronic wiring harnesses and protect electronic control components. An electric push rod is installed on the top of the support frame 2, and a lifting frame 3 is connected to the support frame 2 via the electric push rod at its top. A protective shell 301 is fixedly installed on the frame 1, covering the surface of the lifting frame 3. Regardless of the height of the lifting frame 3, it is always protected by the protective shell 301. The height positions of the two lifting frames 3 are corresponding. A first fixed frame 16 is installed between the two lifting frames 3 near the front of the vehicle via a fixed plate. Multiple limiting rods 17 are connected to the two lifting frames 3 near the rear of the vehicle. Two second fixed frames 19 are slidably connected to the multiple limiting rods 17. A lead screw 18 is rotatably connected to the lifting frame 3 facing the second fixed frame 19. Driven by the internal drive motor of the lifting frame 3, the lead screws 18 on both sides are threadedly connected to the two second fixed frames 19 respectively. The rotation of the drive screws 18 allows the two second fixed frames 19 to move freely along the axial direction of the limit rod 17 within a certain range. Both the first fixed frame 16 and the second fixed frame 19 are provided with mounting slots, and the mounting slots match the shape of the sowing component 20. The sowing component 20 is a roller-type seeder commonly used in the prior art. By controlling the push rod at the top of the support frame 2, the lifting frame 3 can be raised and lowered freely. The sowing component 20 moves with the trolley and penetrates into the soil for dense sowing. The sowing depth is determined by the height of the lifting frame 3. The drive motor inside the two lifting frames 3 drives the lead screws 18 to rotate, allowing the two second fixed frames 19 to move freely. The sowing components on the second fixed frames 19 also sow at the same speed, and sow multiple rows of peanut seeds at the same time. The row width is determined by the position of the second fixed frame 19. The sowing speed and row width can be freely adjusted quickly with simple adjustments.

[0027] The storage box 5 is fixed together by the fixed box 4 and the frame 1. Peanut seeds are stored in advance in multiple storage bins 6 inside the storage box 5. When the control switch at the bottom of the storage bin 6 is turned on, the peanut seeds enter the top funnel of the sowing device 20 through the discharge pipe 7. The discharge pipe 7 can extend and retract freely to adapt to the movement of the sowing device 20 of the second fixed block 19. The storage box 5 is equipped with electric heating components and ventilation components, which can freely control the temperature, humidity and ventilation of the multiple storage bins 6 to ensure that the peanut seeds are stored in a safe environment. They are only dropped into the bottom sowing device 20 for sowing when needed, which greatly improves the quality of peanut seeds. The design of multiple storage bins 6 is also suitable for agricultural needs of planting at different seed spacings.

[0028] After peanut seeds are planted, to improve their breeding condition, the device fertilizes them promptly. A partition plate 10 is fixedly connected to the bottom of the storage box 5, separating the sowing area from the fertilization area. A fertilizer hopper 8 is connected to both the storage box 5 and the frame 1. The fertilizer hopper 8 is divided into multiple fertilizer compartments 801 by partitions 9, used to store various granular fertilizers to meet the sowing and breeding needs of different soil types. Before sowing, a simple soil sample and test are performed to determine which fertilizers are needed. During sowing, the specific position is controlled by an electric actuator inside the partition plate 10. When the closed arc plate 30 is opened, the fertilizer in the specific fertilizer compartment 801 falls into the fertilizer transport pipe 11 through the discharge port 12. The transport blades 13 inside the fertilizer transport pipe 11 rotate, concentrating the fertilizer in the middle and falling through the pipe into the bottom fixed mixing tank 14. The bottom control valve of the mixing tank 14 is opened, and the granular fertilizer falls to the bottom fertilizer drop pipe 15 and reaches the soil surface. The fertilizer drop pipe 15 is a branch pipe and has a through hole at the bottom, which can make the fertilizer fall more evenly in the soil area where the peanut seeds are planted. No matter where the second fixed frame 19 and the sowing component 20 on it are moved, they can be fully fertilized.

[0029] Before controlling the second fixed frame 20 to a suitable angle position for sowing, the internal drive motor of the movable block 24 rotates, controlling the gear 25 inside the movable block 24 to rotate. The gear 25 meshes with the rack 23 on the inner wall of the limiting groove 22 of the guide rail frame 21, allowing the movable block 24 to move freely inside the guide rail frame 21. Multiple movable blocks 24 correspond to the sowing positions of the sowing component 20. A fixed rod 29 is fixedly installed on the frame 1 below the partition plate 10. The bottom of the movable block 24 facing the fixed rod 29 clamps one end of the scraper frame 28 through the connecting frame 27. The movable block 24 is slidably connected to the fixed rod 29. A drive frame 26 is mounted on the bottom of the movable block 24 via a small push rod. The drive frame 26 is slidably connected to the scraper frame 28. By controlling the extension and retraction of the small push rod at the bottom of the movable block 24, the scraper frame 28 can be rotated around the fixed rod 29, thereby controlling the depth of contact between the scraper frame 28 and the soil, achieving the effect of adjusting the scraping depth. When the movable block 24 moves, the connecting frame 27 moves synchronously with the scraper frame 28, ensuring that the scraper frame 28 corresponds to the sowing area of ​​the sowing component 20, ensuring that the fertilizer in the peanut seed breeding area is covered by the soil, and improving seed survival rate. This device combines sowing and fertilization, and the clock can adapt to simultaneous sowing of multiple rows. The sowing width can also be easily adjusted without replacing other sowing equipment, making it highly adaptable.
