[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This application uses two spiral conveyor rods to transport seeds inside the feed pipe to both sides, then the seeds fall from the guide pipe and enter the fixed frame, thereby allowing the seeds to enter the collection hole inside the fixed sleeve for seed transport. By setting up conveying components such as spiral conveyor rods and rotating rods, driven by a second motor, and cooperating with the first and second bevel gears, bidirectional synchronous seed supply is achieved, ensuring that the seeds are evenly and stably transported from the hopper to each guide pipe and fixed frame, further ensuring the continuity and reliability of the sowing process.

[0018] 3. This application uses a hydraulic cylinder to drive a hinge plate to descend. When the hinge plate descends, it drives a pressure plate to descend. After the pressure plate descends, it pushes a slider to descend and causes the slider to slide inside the swing arm. This causes the swing arm to deflect downward along the junction point. When the swing arm deflects downward, it drives the bent rod and the digging plate to press down, causing the digging plate to push the soil to turn over and cover the seeds with soil, thus facilitating subsequent seed growth. The hydraulic cylinder drives the swing arm and the digging plate to turn up and down, realizing the soil covering operation for the sown seeds. The spring and slider structure enhances the buffering and adaptability of the swing arm, ensuring uniform soil covering and improving the survival rate and operation efficiency after sowing.

[0028] In use, this solution connects to the ditching machine head pin via the connecting plate 1, allowing the head unit to move into the field. The front ditching machine then turns the soil to form planting furrows. Seeds are introduced into the worm gear 10, falling into the distribution pipes 18 on both sides and being discharged from the two distribution pipes 18 into the conveying pipes 17 on both sides. The second motor 22 starts and drives the first bevel gear 23 to rotate, which in turn drives the two second bevel gears 24 to rotate. The rotation of the two second bevel gears 24 then drives the two rotating rods 21 and the screw conveyor 20 to rotate, thus causing the two... A spiral conveyor 20 transports the seeds inside the conveying pipe 17 to both sides, then causes the seeds to fall from the guide pipe 15 and enter the fixed frame 13, thereby allowing the seeds to enter the collection hole 7 inside the fixed sleeve 5. This process of seed transport is achieved by setting up conveying components such as the spiral conveyor 20 and the rotating rod 21, driven by the second motor 22, and cooperating with the first bevel gear 23 and the second bevel gear 24 to achieve bidirectional synchronous seed supply. This ensures that the seeds are evenly and stably transported from the hopper 19 to each guide pipe 15 and the fixed frame 13, further guaranteeing the continuity and reliability of the sowing process.
[0029] The third motor 30 starts and drives the guide shaft 31 to rotate, which in turn drives the fourth bevel gear 33 to rotate, which in turn drives the third bevel gear 32 to rotate. The rotation of the third bevel gear 32 drives the rotating shaft 8 to rotate, which in turn drives the inclined rod 35 to rotate. Then the inclined rod 35 drives the swing rod 36 to move back and forth, which in turn drives the push rod 37 and the baffle 39 to move back and forth. The baffle 39 moves back and forth inside the sliding sleeve 38, which separates the baffle 39 from the bottom of the collection hole 7, allowing the seeds inside the collection hole 7 to fall into the planting furrow. This allows for precise and accurate seed distribution and planting. The seed distribution mechanism uses a seed-discharging wheel type with multiple collection holes 7 arranged in a ring on the feeding wheel 6. With the help of the worm gear 12 and worm 10, and driven by the first motor 11, it can achieve precise and continuous seed extraction and discharging, effectively avoiding seed clogging and repeated discharging, improving the uniformity and accuracy of sowing, and promoting the uniformity of crop growth.
[0030] The first motor 11 starts and drives the worm gear 10 to rotate, which in turn drives the worm wheel 12 to rotate. When the worm wheel 12 rotates, it drives the feeding wheel 6 to rotate, which in turn drives the multiple collecting holes 7 to rotate. This is done to switch the multiple collecting holes 7 so that the next collecting hole 7 carrying seeds moves to the position of the baffle 39 and is discharged.
[0031] By installing a vision sensor on the mounting frame 2, the seed position is monitored, and the hydraulic cylinder 44 is activated. The hydraulic cylinder 44 drives the hinge plate 45 to descend. When the hinge plate 45 descends, it drives the pressure plate 47 to descend. After the pressure plate 47 descends, it pushes the slider 46 to descend and causes the slider 46 to slide inside the swing arm 41. This causes the swing arm 41 to deflect downward along the junction point. When the swing arm 41 deflects downward, it drives the bent rod 49 and the digging plate 42 to press down, causing the digging plate 42 to push the soil to turn over and cover the seeds with soil, thus facilitating subsequent seed growth. The hydraulic cylinder 44 drives the swing arm 41 and the digging plate 42 to turn up and down, realizing the soil covering operation of the sown seeds. The structure of the spring 48 and the slider 46 enhances the buffer and adaptability of the swing arm, ensuring uniform soil covering and improving the survival rate and operation efficiency after sowing.
[0032] By rotating the vertical rod 53, the sixth bevel gear 52 is rotated, which in turn drives the two fifth bevel gears 51 to rotate. When the two fifth bevel gears 51 rotate, they drive the two threaded rods 26 to rotate, which in turn drives the two side plates 27 and side rods 28 to move. When the side rods 28 move, they drive the guide shaft 31 and the fixed shell 34 to move, allowing the moving plate 4 to slide inside the chute 3. This adjusts the distance between the two feeding wheels 6 to adapt to different soil planting environments. This device, by setting an adjustable spacing double-row planting structure, including the moving plate 4, the fixed sleeve 5, and the feeding wheels 6, along with the chute 3 and threaded rods 26 and other adjustment mechanisms, can flexibly adjust the distance between the two feeding wheels 6 according to the planting row spacing requirements, adapting to the requirements of different crops and planting environments. This improves the versatility and applicability of the device, thereby realizing flexible configuration of precision sowing.
