[0002] In the agricultural production process, sowing is a vital link. Among them, the seeder can be used to spread seeds evenly on the ground, which is suitable for large-scale sowing. For example, the drill is mainly used for sowing small seeds such as cereals, vegetables, and forage grass. The seeds are discharged into the opened grooves through the seed meter. The hole seeder sows seeds in holes according to a certain row spacing and hole spacing, which is suitable for row crops such as corn, cotton, beets, sunflowers, and beans.

According to the amount of water required for the sown seeds, the amount of water in the cylindrical groove 23 between the piston disc 24 and the inner ring surface of the silo 2 is adjusted by the adjusting component, and the amount of water is the amount of water required for the seeds. Then, the seeder is installed on the tractor, and then sowing can be carried out; More specifically, during sowing, the tractor will drive the seeder to move in the field, the furrowing disc 15 on the seeder will dig furrows on the field, and at the same time the pneumatic seed metering device 12 will sort the seeds one by one, and the sorted seeds will fall into the seed delivery tube 14 in sequence. Since the seed delivery tube 14 is connected to one of the cylindrical grooves 23, the seeds entering the seed delivery tube 14 will first pass through the sensor 141, and then fall into the cylindrical groove 23 opposite to the seed delivery tube 14, and then the motor 31 will be controlled to rotate, and the motor 31 will drive the fixed disk 3 to rotate, and the fixed disk 3 will rotate. The disk 3 drives the annular plate 22 to rotate clockwise, and the annular plate 22 drives the cylindrical groove 23, the piston plate 24 and the adjusting assembly to rotate. The rotating cylindrical groove 23 drives the seeds to rotate. When the cylindrical groove 23 containing the seeds rotates to the position below the water pipe 32, the cylindrical groove 23 originally located below the seed delivery tube 14 rotates to align with the seed delivery tube 14. When the seeds in the seed delivery tube 14 continue to fall into the cylindrical groove 23, the motor 31 continues to be controlled to rotate until the next cylindrical groove 23 is aligned with the seed delivery tube 14 again, and the cycle continues. Furthermore, when the cylindrical groove 23 containing seeds is aligned with the water pipe 32, the water in the water pipe 32 will flow into the cylindrical groove 23. Since the water pipe 32 is directly connected to the water tank 17 and the water pipe 32 is vertically downward, the cylindrical groove 23 can be quickly filled. At the same time, since the water pipe 32 is fixedly connected to the mesh layer 33 on one side close to the cylindrical groove 23, it is possible to prevent the seeds from being flushed into the water pipe 32 during the process of water entering the cylindrical groove 23. With the intermittent rotation of the annular plate 22, the cylindrical groove 23 containing seeds and water will continue to rotate clockwise. Since the inner ring surface of the silo 2 is provided with a sealing The cylindrical groove 23 rotates along the sealing layer, so as to block the cylindrical groove 23 and prevent the water in the cylindrical groove 23 from flowing out. When the cylindrical groove 23 filled with seeds and water rotates to the position of the discharge pipe 34 and is aligned with the discharge pipe 34, the water and seeds in the cylindrical groove 23 flow downward, and will first enter the discharge pipe 34, and then fall into the ditch opened by the ditching plate 15. The roller 16 passing by will bury the seeds in the soil. With the cyclic rotation of the annular plate 22, more seeds can be brought to the position of the discharge pipe 34, and the seeds can be sown in the opened ditch, so as to repeat the cycle. Furthermore, by controlling the annular plate 22 to drive the multiple cylindrical grooves 23 to rotate in a circular manner, the seeds that fall one by one can be moved by the multiple cylindrical grooves 23, and then water is added to the cylindrical grooves 23 in turn, and the water and the seeds are discharged into the ditch together. Since the water capacity of the cylindrical grooves 23 between the piston disk 24 and the inner ring surface of the silo 2 is the amount of water required by the seeds, the amount of water required for the seeds can be controlled more accurately, thereby avoiding uneven watering of the seeds. At the same time, since the seeds are directly located in the water and the seeds and water fall together, it is possible to avoid the existing use of sprinklers to spray water on the sown seeds. When the pneumatic seed metering device 12 vibrates and causes the position of seed sowing to change, the watering position will not match the sowing position, resulting in misalignment of the seeds and the water.

[0021] Embodiment 2: The adjustment assembly includes an adjustment disk 4; the adjustment disk 4 rotates on the inner ring of the annular plate 22; the middle of the adjustment disk 4 is fixedly connected to an adjustment rod 41, and one side of the adjustment rod 41 is rotatably mounted on the fixed disk 3, and the other side extends out of a cylinder 42; The surface of the adjusting disk 4 is provided with arc grooves 43 which are evenly arranged, and the number of the arc grooves 43 is the same as the number of the guide rods 26, and the guide rods 26 all slide in the corresponding arc grooves 43; The cylinder 42 extends out of one side of the silo 2, and is fixedly connected to a circular plate 44 at the inner circle of the cylinder 42, and the adjusting rod 41 passes through the circular plate 44 and is rotatably connected to the circular plate 44; The outer ring surface of the cylinder 42 is threadedly engaged with locking bolts 45 arranged evenly, and the locking bolts 45 pass through the circular plate 44 and abut against the adjusting rod 41; the outer ring of the adjusting rod 41 is provided with scale lines 46 on the circular plate 44, and the scale lines 46 are marked with corresponding water volumes; the adjusting rod 41 is provided with a pointer; Specifically, when it is necessary to sow seeds of different crops, the water volume of the cylindrical groove 23 between the piston disc 24 and the inner ring surface of the silo 2 can be adjusted according to the moisture required by the seeds. When adjusting, first use a wrench to loosen the locking bolt 45, and then rotate the adjusting rod 41 forward or reverse. In the process of rotating the adjusting rod 41, the adjusting rod 41 will drive the adjusting disk 4 to rotate, and the rotating adjusting disk 4 will drive the arc groove 43 to rotate. Since the guide rods 26 all slide in the arc groove 43, the guide rods 26 will be controlled to slide in the arc groove 43. The sliding guide rods 26 will push the connecting rod 25 to move, and the connecting rod 25 will drive the piston disc 24 to slide upward or downward in the cylindrical groove 23. When the pointer on the adjusting rod 41 is aligned with the scale line 46 of the amount of water required for the seeds, stop rotating the adjusting rod 41, and use the locking bolt 45 to limit and fix the adjusting rod 41, and then it can be used; More specifically, by utilizing the adjusting rod 41 to control the rotation of the adjusting disk 4, the piston disk 24 can be indirectly driven to move in the cylindrical groove 23, so that the water volume of the cylindrical groove 23 between the piston disk 24 and the inner ring surface of the silo 2 can be adjusted according to the required water volume of different crop seeds, thereby avoiding the situation where the water volume of the cylindrical groove 23 between the piston disk 24 and the inner ring surface of the silo 2 is fixed, and only seeds of one crop can be sown and watered, thereby improving the practicality of the seeder.

[0022] Embodiment 3: Air passages 5 are provided on both sides of the cylindrical groove 23 on the outer surface of the annular plate 22, and the air passages 5 extend between the piston plate 24 and the regulating plate 4; the two air passages 5 are staggered with the seed delivery pipe 14, the water pipe 32 and the feed pipe 34; The air passage 5 extends to one side between the piston plate 24 and the regulating plate 4 and is fixedly connected to an air pipe 51, and the air pipe 51 extends to the piston plate 24; a one-way valve is installed in the air pipe 51; An air bin 52 is provided at the bottom of the round bin 2, and the feed pipe 34 passes through the air bin 52; a joint is fixedly connected to the air bin 52, and the joint is connected to the air pump; The bottom of the round silo 2 is provided with two air holes 53, and the air holes 53 are located in the air silo 52, and the air passages 5 on both sides of the cylindrical groove 23 corresponding to the feeding pipe 34 overlap with the air holes 53; In this embodiment, the air pipe 51 is a telescopic pipe. When the piston plate 24 moves, the air pipe 51 will be extended or contracted. In this embodiment, the end surface of each piston disc 24 away from the connecting rod 25 is fixedly connected to the top cover 54, and the top cover 54 is provided with evenly arranged through holes 55; In this embodiment, two conduits 56 are fixedly connected in the gas bin 52, and both conduits 56 extend into the feed pipe 34; Specifically, since a one-way valve is provided on the air pipe 51, when the water in the water pipe 32 enters the cylindrical groove 23, the one-way valve can prevent the water from flowing into the air pipe 51. When the cylindrical groove 23 filled with seeds and water rotates to align with the discharge pipe 34, the air passages 5 on both sides of the cylindrical groove 23 also coincide with the air holes 53. Therefore, the gas in the air chamber 52 will enter the air passage 5 through the air holes 53, and then the gas in the air passage 5 will enter the air pipe 51. The gas entering the air pipe 51 will be ejected, and the ejected gas will eject the seeds and water, thereby preventing the seeds from adhering to the cylindrical groove 23 and being unable to be sown, and at the same time reducing the amount of water remaining in the cylindrical groove 23. More specifically, since the piston disc 24 is fixedly connected to the top cover 54, and the top cover 54 is provided with evenly arranged through holes 55, the gas ejected from the air pipe 51 will be ejected from the evenly arranged through holes 55. In this process, the range of gas ejection can be increased, so that the cylindrical groove 23 can be more comprehensively jetted, thereby further preventing the seeds from adhering to the cylindrical groove 23 and being unable to be sown; Furthermore, since the conduit 56 in the gas bin 52 extends into the feed pipe 34, the gas in the gas bin 52 will enter the feed pipe 34 through the conduit 56. The gas entering the feed pipe 34 will act on the inner wall of the feed pipe 34. When seeds and water pass through, the gas ejected from the conduit 56 will continue to push the seeds and water to fall downward, thereby preventing the seeds from adhering to the feed pipe 34 and being unable to be sown. At the same time, the gas entering the feed pipe 34 will be ejected from the bottom of the feed pipe 34, thereby ejecting the soil adhering to the bottom of the feed pipe 34, thereby preventing the soil from clogging the feed pipe 34 and making it impossible for the feed pipe 34 to discharge.

[0023] On the other hand, the present invention further provides a method for using the sprinkler device for a seed drill, which is applicable to the sprinkler device for a seed drill, and comprises the following steps: Step 1: First, seeds are placed in a plurality of seed boxes 13, then water is added to the water tank 17, and then the seeder is installed on the tractor, and then the sowing can be carried out; Step 2: During sowing, the tractor will drive the seeder to move in the field, and the furrowing disc 15 on the seeder will furrow on the field. At the same time, the pneumatic seed metering device 12 will sort the seeds one by one, and the sorted seeds will fall into the seed delivery tube 14 in sequence, and then fall into the cylindrical groove 23 opposite to the seed delivery tube 14; Step three: Control the annular plate 22 to drive the multiple cylindrical grooves 23 to rotate in a circular motion, and the seeds that fall one by one can be moved through the multiple cylindrical grooves 23, and then water is added to the cylindrical grooves 23 one by one, and the water and seeds are discharged into the ditch together for sowing.
