Description

Technical Field

[0001] This invention relates to the field of forestry nursery seeders, and in particular to a forestry nursery seeder. Background Technology

[0002] A forestry nursery seeder is a mechanical device specifically designed for sowing operations in forestry nurseries. It achieves mechanized and efficient sowing operations by evenly and quantitatively scattering forest tree seeds on seedbeds.

[0003] When using a seeder to sow seeds in forestry production, traditional seeders often use fixed sowing depths and forces, making it difficult to adapt to soils of varying hardness. In hard soils, the seeder may be damaged due to excessive resistance, while in soft soils, it may sow too deep or too shallow, affecting seed germination and reducing seed survival rates. This also results in the low applicability of traditional seeders, making them inconvenient to use. Summary of the Invention

[0004] This invention addresses the problem that traditional seeders, which often employ fixed sowing depths and forces, are ill-suited to soils of varying hardness during seeding operations in forestry production. In hard soils, excessive resistance can damage the seeder, while in soft soils, sowing may result in excessively deep or shallow planting, affecting seed germination and reducing seed survival rates. This invention provides a forestry nursery seeder to address these issues.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a forestry nursery seeder, comprising a seeder body and a first belt, a push rod fixedly connected to one side of the seeder body, a circular frame fixedly connected to the inner wall of the seeder body, a plurality of feed hoppers radially connected to the outer surface of the circular frame, a seeding roller rotatably connected to the inner wall of the circular frame, the two ends of the seeding roller being respectively connected to the two sides of the inner wall of the seeder body, a drive motor fixedly connected to one side of the seeder body, and the inner walls of the two ends of the first belt respectively sleeved on one end of the seeding roller and the drive motor. On the outer surface of the output end of the motor, several sowing grooves are formed on the outer surface of the sowing roller. A soil loosening device is provided on the outer surface of the circular frame. An irrigation device is provided on one side of the inner wall of the seeder body. An auxiliary device is provided on one side of the seeder body. The soil loosening device can loosen the soil in the field to be planted before planting. At the same time, the depth of loosening and sowing can be adjusted according to the sowing needs. The irrigation device can irrigate the soil after sowing. The auxiliary device can scrape the drilled soil to level it and help the seeder body cover the sown seeds.

[0006] The aforementioned components achieve the following effect: When using the seeder body to sow seeds during forestry production, seeds are placed in the feed hopper and then fall into the sowing trough on the sowing roller through the hopper's outlet. The drive motor is then activated, causing the sowing roller to rotate within the seeder body and the inner wall of the circular frame. Simultaneously, the operator holds the push rod and propels the seeder body across the planting field. The outer surface of the sowing roller is tightly pressed against the inner wall of the circular frame, thus ensuring a fixed number of seeds fall into the sowing trough. As the sowing roller rotates, the seeds in the sowing trough move along the inner wall of the circular frame to a certain position. The soil is then loosened by a soil loosening device and guided into the soil for planting. Irrigation is then performed by an irrigation device. Finally, an auxiliary device levels the soil and covers the planted seeds. By continuously sowing seeds through several sowing troughs at intervals, the seeder body achieves continuous sowing.

[0007] Preferably, the soil loosening device includes a support frame, several second belts, two third belts, and a dual-shaft motor. Several guide pipes are threaded and connected to the outer surface of the circular frame. A grooved ring frame is rotatably connected to one end of each guide pipe. Second telescopic rods are symmetrically fixed to one side of the grooved ring frame. Winding rollers are rotatably connected to the inner walls of both ends of the grooved ring frame. First torsion springs are sleeved and connected to the outer surfaces of both ends of the winding rollers. The two ends of the first torsion springs are respectively fixedly connected to one side of the winding roller and one side of the inner wall of the grooved ring frame. The outer surface of the winding roller is fixed... A pull rope is connected to the guide tube. A round rod is slidably connected to the outer surface of one end of the guide tube. A circular ring block is rotatably connected to the outer surface of the round rod. One end of each of the two second telescopic rods is fixedly connected to one side of the circular ring block. A toothed ring block is fixedly connected to the outer surface of one end of the circular ring block. A through hole is symmetrically opened on one side of the toothed ring block. A U-shaped block is symmetrically fixedly connected to the outer surface of the circular ring block. A rotating block is rotatably connected to the inner wall of the U-shaped block. A second torsion spring is sleeved and connected to the outer surface of both ends of the rotating block. The two ends of the second torsion spring are respectively connected to the inner wall of the U-shaped block and one side of the rotating block. The rotating block is fixedly connected to one side of a drill block. One end of the pull rope passes through a through hole and is fixedly connected to one end of the drill block. The inner walls of several second belts are respectively sleeved and connected to the outer surfaces of several adjacent ring blocks. One side of the bracket is connected through to the outer surfaces of several ring blocks. Fixed frames are fixedly connected to both sides of the dual-axis motor. One side of the fixed frame is fixedly connected to one side of the bracket. One output end of the dual-axis motor is fixedly connected to a first gear. The outer surface of the first gear meshes with the outer surface of the gear ring block. The other output end of the dual-axis motor is fixedly connected to a first telescopic rod. One end of the first telescopic rod is fixedly connected to a second gear. One end of the second gear is rotatably connected to the outer surface of the ring frame. A third gear is symmetrically rotatably connected to the outer surface of the ring frame. The outer surface of the third gear meshes with the outer surface of the second gear. A reciprocating screw is symmetrically rotatably connected to the outer surface of the ring frame. A sliding hole is symmetrically opened on one side of the bracket. The outer surface of the reciprocating screw is slidably connected to the inner wall of the sliding hole. One end of the reciprocating screw is fixedly connected to a limit block.

[0008] The effect achieved by the above components is as follows: By setting up a soil loosening device, after the seeds in the seeding trough move along the inner wall of the circular frame to a certain position due to the rotation of the seeding roller, the seeds will fall into the guide pipe and then enter between the round rod and the two drill blocks. At this time, the dual-axis motor on the fixed frame is started to drive the first gear to rotate, which in turn drives one of the toothed ring blocks to rotate in the inner wall of the support and on the outer surface of the round rod, and drives the circular ring block, two U-shaped blocks, two rotating blocks and two drill blocks to rotate. Then, under the drive of the second belt, several pairs of drill blocks can be driven to rotate. At the same time, under the connection of the second telescopic rod, the grooved ring frame, the winding roller and the pull rope will also rotate. At this time, the other output end of the dual-axis motor is started to drive the first telescopic rod and the second gear to rotate on the circular frame, which drives the two third gears to rotate in the same direction on the outer surface of the circular frame. Then, under the drive of the third belt, the two reciprocating screws can be driven to rotate on the circular frame, so that the support moves downward on the reciprocating screws through the sliding hole, so that the drill blocks and the circular ring blocks pass through the round rod. Sliding downwards on the outer surface of the guide tube, the drill block and the ring block not only move downwards but also rotate, loosening the soil in the sown field and breaking up the harder soil to make it softer. As the drill block, ring block, and round rod move downwards, they pull the first and second telescopic rods apart. At the same time, one end of the pull rope is continuously unwound on the winding roller, causing the first torsion spring to deform. When the pull rope is unwound to a certain position, the other end pulls one end of the drill block, causing it to rotate within the inner wall of the U-shaped block via the rotating block. The second torsion spring deforms, causing its other end to open, sowing the seeds inside into the drilled soil. When the reciprocating screw drives the support to move upward, the drill block will return to its original position and close under the reset action of the second torsion spring. At the same time, the first torsion spring will drive the winding rod to return to its original position and rewind one end of the pull rope, making it easy to continue the operation for the next sowing. Through this operation, the hardness of the sowing soil can be reduced, making the seeder body adaptable to different planting environments, improving its adaptability, while ensuring that the planting depth of each seed is consistent, thus improving the seed survival rate.

[0009] Preferably, the inner walls of the seeder body are symmetrically provided with sliding grooves on both sides, and the two ends of the bracket are slidably connected to the inner walls of the two pairs of sliding grooves respectively.

[0010] The effect achieved by the above components is that by setting the sliding groove, the two ends of the bracket can be limited, making it less prone to shaking when moving up and down, and making the movement more stable.

[0011] Preferably, a folded cloth cover is fixedly connected to the outer surface of the circular frame, and one end of the folded cloth cover is fixedly connected to one side of the support.

[0012] The effect achieved by the above components is that by setting up a folding cloth cover, the outer surfaces of the dual-shaft motor, the first gear, the gear ring block, the second gear, the third gear, and the guide pipe can be protected, preventing soil from splashing between the first gear and the gear ring block during sowing and causing them to get stuck and affect the movement.

[0013] Preferably, a plurality of circular rollers are rotatably connected to the inner wall of one end of the through hole, and the plurality of circular rollers are arranged at equal intervals.

[0014] The effect achieved by the above components is that by setting up the circular roller, the friction between the through hole bend and the pull rope can be reduced, thereby increasing the service life of the pull rope.

[0015] Preferably, the irrigation device includes a water tank, one side of which is fixedly connected to one side of the inner wall of the seeder body, the outer surface of the inlet of the water tank is connected through to one side of the inner wall of the seeder body, a tank cover is threadedly connected to the outer surface of the inlet of the water tank, a water pump is connected through to one side of the water tank, and a spray frame is fixedly connected to the outlet of the water pump.

[0016] The effect achieved by the above-mentioned components is as follows: by setting up the irrigation device, before using the main body of the seeder, first unscrew the box cover, pour water into the water tank, and then close the box cover. After the soil loosening device works with the main body of the seeder to sow the seeds into the soil, the water pump is started to draw the water in the water tank into the interior of the water spray frame, and then discharges it from several water outlets to irrigate the freshly sown seeds, provide them with water, promote seed germination, and improve seed survival rate.

[0017] Preferably, filter screens are fixedly connected to the inner walls of several outlets of the water spray frame.

[0018] The effect achieved by the above components is as follows: by setting up a filter screen, the inner wall of the water sprayer outlet can be protected, so that soil is not easily splashed into the inner wall of the water sprayer during sowing and drilling, thus avoiding blockage at the outlet of the water sprayer and improving its service life.

[0019] Preferably, both ends of the water spray frame are fixedly connected to a round hole frame, and one side of the round hole frame is fixedly connected to one side of the seeder body.

[0020] The effect achieved by the above-mentioned components is that by setting the round hole bracket, the two ends of the water spray bracket can be supported and fixed, making it less prone to shaking during use and improving its stability.

[0021] Preferably, the auxiliary device includes a scraper and a pad block. A threaded rod is fixedly connected to one side of the scraper, and a threaded hole block is threadedly connected to the outer surface of the threaded rod. A rectangular groove is opened on one side of the seeder body, and a rectangular hole is opened on one side of the inner wall of the rectangular groove. The scraper and the threaded rod are slidably connected to the rectangular groove and the rectangular hole, respectively.

[0022] The effects achieved by the above-mentioned components are as follows: By setting the auxiliary device, after the seeder body is placed in the planting field, the scraper and threaded rod can be manually slid down into the rectangular groove and rectangular hole to a certain position according to the height of the seeder from the ground. Then, the screw hole block is turned to rotate it to a certain position so that one side of it abuts against the side of the seeder body, fixing the scraper to the limiting post. After the seeder body and the soil loosening device have finished sowing the seeds, the scraper will move along with the seeder body as it is being driven, scraping the soil that has been drilled open and covering the sown seeds, improving sowing efficiency and facilitating the use of the seeder body.

[0023] Preferably, the pad is fitted onto the outer surface of the threaded rod, and the pad is positioned between the threaded hole block and one side of the seeder body.

[0024] The effect achieved by the above components is that by setting the pad, the contact area between the screw hole block and the seeder body can be increased, making it more secure when fixing the scraper.

[0025] In summary, the beneficial effects of the present invention are as follows:

[0026] By setting up a soil loosening device, the soil in the field to be planted can be loosened before planting, reducing soil hardness and making the seeder body adaptable to different planting environments, improving its adaptability, ensuring that each seed is planted at a consistent depth, and improving seed survival efficiency.

[0027] By setting up an irrigation device, water can be provided to the soil after sowing, thereby improving the survival rate of seeds.

[0028] By setting up auxiliary devices, the drilled soil can be leveled, and the main body of the seeder can cover the seeds after sowing, thereby improving sowing efficiency and facilitating the use of the seeder. Attached Figure Description

[0042] Reference Figure 1-11As shown, this embodiment discloses a forestry nursery seeder, including a seeder body 1 and a first belt 10. A push rod 5 is fixedly connected to one side of the seeder body 1. A circular frame 6 is fixedly connected to the inner wall of the seeder body 1. A plurality of feed hoppers 7 are radially connected to the outer surface of the circular frame 6. A sowing roller 8 is rotatably connected to the inner wall of the circular frame 6. The two ends of the sowing roller 8 are respectively connected to the two sides of the inner wall of the seeder body 1. A drive motor 9 is fixedly connected to one side of the seeder body 1. The inner walls of the two ends of the first belt 10 are respectively sleeved on one end of the sowing roller 8 and the drive motor 9. On the outer surface of the output end, the outer surface of the seeding roller 8 is provided with several seeding grooves 11, the outer surface of the circular frame 6 is provided with a soil loosening device 2, one side of the inner wall of the seeder body 1 is provided with an irrigation device 3, and one side of the seeder body 1 is provided with an auxiliary device 4. The soil loosening device 2 can loosen the soil of the field to be planted before planting, and can also adjust the soil loosening and sowing depth according to the sowing needs. The irrigation device 3 can irrigate the soil after sowing. The auxiliary device 4 can scrape the drilled soil flat and assist the seeder body 1 in covering the seeds after sowing. When using the seeder body 1 to sow seeds during forestry production, the seeds are placed in the feed hopper 7 and then fall into the sowing trough 11 on the sowing roller 8 through the outlet of the feed hopper 7. At this time, the drive motor 9 is started to drive the sowing roller 8 to rotate within the inner wall of the seeder body 1 and the circular frame 6. Simultaneously, the operator holds the push rod 5 to push the seeder body 1 to move in the planting field. The outer surface of the sowing roller 8 is in close contact with the inner wall of the circular frame 6, so the number of seeds falling into the sowing trough 11 is fixed. When the sowing roller 8 rotates and drives the seeds in the sowing trough 11 to move along the inner wall of the circular frame 6 to a certain position, the soil is loosened by the loosening device 2 and then guided into the soil for planting. Then, the seeds are irrigated by the irrigation device 3. Finally, the auxiliary device 4 scrapes the soil to level it and covers the planted seeds. By continuously receiving and sowing seeds through several sowing troughs 11, the seeder body 1 achieves the effect of continuous sowing.

[0043] Reference Figure 1-11As shown, this embodiment discloses a soil loosening device 2 including a support 215, several second belts 214, two third belts 222, and a dual-shaft motor 216. Several guide pipes 21 are connected to the outer surface of the circular frame 6. A grooved ring frame 22 is rotatably connected to the outer surface of one end of the guide pipe 21. A second telescopic rod 225 is symmetrically fixed to one side of the grooved ring frame 22. A winding roller 23 is rotatably connected to the inner wall of both ends of the grooved ring frame 22. A first torsion spring 24 is sleeved and connected to the outer surface of both ends of the winding roller 23. The two ends of the first torsion spring 24 are fixedly connected to one side of the winding roller 23 and one side of the inner wall of the grooved ring frame 22, respectively. A pull rope 2 is fixedly connected to the outer surface of the winding roller 23. 5. A round rod 26 is slidably connected to the outer surface of one end of the guide tube 21. A circular ring block 27 is rotatably connected to the outer surface of the round rod 26. One end of each of the two second telescopic rods 225 is fixedly connected to one side of the circular ring block 27. A toothed ring block 28 is fixedly connected to the outer surface of one end of the circular ring block 27. A through hole 29 is symmetrically opened on one side of the toothed ring block 28. A U-shaped block 210 is symmetrically fixedly connected to the outer surface of the circular ring block 27. A rotating block 211 is rotatably connected to the inner wall of the U-shaped block 210. A second torsion spring 212 is sleeved and connected to the outer surfaces of both ends of the rotating block 211. The two ends of the second torsion spring 212 are fixedly connected to the inner wall of the U-shaped block 210 and one side of the rotating block 211, respectively. A drill block 213 is fixedly connected to the side. One end of the pull rope 25 passes through the through hole 29 and is fixedly connected to one side of the drill block 213. The inner walls of several second belts 214 are respectively sleeved and connected to the outer surfaces of several adjacent ring blocks 27. One side of the bracket 215 is connected through to the outer surfaces of several ring blocks 27. Both sides of the dual-axis motor 216 are fixedly connected to the fixing bracket 217. One side of the fixing bracket 217 is fixedly connected to one side of the bracket 215. One output end of the dual-axis motor 216 is fixedly connected to the first gear 218. The outer surface of the first gear 218 meshes with the outer surface of the gear ring block 28. The other output end of the dual-axis motor 216 is fixedly connected to the second gear 218. A telescopic rod 219 is provided. One end of the first telescopic rod 219 is fixedly connected to a second gear 220. One end of the second gear 220 is rotatably connected to the outer surface of the ring frame 6. A third gear 221 is symmetrically rotatably connected to the outer surface of the ring frame 6. The outer surface of the third gear 221 meshes with the outer surface of the second gear 220. A reciprocating screw 223 is symmetrically rotatably connected to the outer surface of the ring frame 6. A sliding hole 224 is symmetrically opened on one side of the bracket 215. The outer surface of the reciprocating screw 223 is slidably connected to the inner wall of the sliding hole 224. The reciprocating screw 223 and the bracket 215 form a ball screw mechanism through the sliding hole 224. One end of the reciprocating screw 223 is fixedly connected to a limit block 226.After the seeds in the seeding trough 11 move along the inner wall of the circular frame 6 to a certain position as the seeding roller 8 rotates, they fall into the guide pipe 21 and then enter the space between the round rod 26 and the two drill blocks 213. At this time, the dual-axis motor 216 on the fixed frame 217 is activated, which drives the first gear 218 to rotate. This causes one of the gear ring blocks 28 to rotate on the inner wall of the support 215 and the outer surface of the round rod 26, and drives the circular ring block 27, the two U-shaped blocks 210, the two rotating blocks 211, and the two drill blocks 213 to rotate. Then, under the transmission of the second belt 214, several pairs of drill blocks can be driven to rotate. When block 213 rotates, the second telescopic rod 225, connected to the grooved ring frame 22, winding roller 23, and pull rope 25, also rotate. Simultaneously, the other output end of the dual-axis motor 216 is activated, causing the first telescopic rod 219 and the second gear 220 to rotate on the ring frame 6. This causes the two third gears 221 to rotate in the same direction on the outer surface of the ring frame 6. Then, driven by the third belt 222, the two reciprocating screws 223 rotate on the ring frame 6, causing the support 215 to move downwards on the reciprocating screws 223 through the sliding hole 224, thus causing the drill block 213 and the ring block 213 to rotate. 7. The round rod 26 slides downward on the outer surface of the guide tube 21. At this time, the drill block 213 and the ring block 27 not only move downward but also rotate, loosening the soil in the sowing field and drilling through the harder soil to make it softer. When the drill block 213, the ring block 27 and the round rod 26 move downward, they will pull the first telescopic rod 219 and the second telescopic rod 225 to stretch apart. At the same time, one end of the pull rope 25 is continuously unwound on the winding roller 23, causing the first torsion spring 24 to deform. When the pull rope 25 is unwound to a certain position, the other end will pull one end of the drill block 213 with the help of the rotating block 211 on the U-shaped block 2. Rotation occurs within the inner wall of the 10, causing the second torsion spring 212 to deform and open its other end, sowing the seeds into the drilled soil. When the reciprocating screw 223 drives the support 215 upward, the second torsion spring 212 resets the drill block 213, causing it to close. Simultaneously, the first torsion spring 24 resets the winding rod, rewinding one end of the pull rope 25 for easy re-operation during the next sowing. This operation reduces the hardness of the sowing soil, allowing the seeder body 1 to adapt to different planting environments, improving its adaptability, and ensuring consistent planting depth for each seed, thus increasing seed survival efficiency. It should be noted that the dual-axis motor 216 is a mature drive technology and device in the existing field. In this solution, its two sides can rotate independently and stop promptly after completing a set number of rotations. Its internal structure, connection method, and principle will not be elaborated further.

[0044] Reference Figure 1-11As shown in the figure, this embodiment discloses that the inner walls of the seeder body 1 are symmetrically provided with sliding grooves 227 on both sides, and the two ends of the bracket 215 are slidably connected to the inner walls of the two pairs of sliding grooves 227 respectively. By setting the sliding grooves 227, the two ends of the bracket 215 can be limited, making it less prone to shaking when moving up and down, and making the movement more stable. A folded cloth cover 228 is fixedly connected to the outer surface of the ring frame 6, and one end of the folded cloth cover 228 is fixedly connected to one side of the bracket 215. By setting the folded cloth cover 228, the outer surfaces of the dual-shaft motor 216, the first gear 218, the gear ring block 28, the second gear 220, the third gear 221 and the guide pipe 21 can be protected, preventing soil from splashing between the first gear 218 and the gear ring block 28 during sowing and causing jamming that affects the movement. A number of circular rollers 229 are rotatably connected to the inner wall of one end of the through hole 29, and the number of circular rollers 229 are arranged at equal intervals. By setting the roller 229, the friction between the bend of the through hole 29 and the pull rope 25 can be reduced, thereby improving the service life of the pull rope 25.

[0045] Reference Figure 1-11 As shown, this embodiment discloses an irrigation device 3 including a water tank 31. One side of the water tank 31 is fixedly connected to one side of the inner wall of the seeder body 1. The outer surface of the inlet of the water tank 31 is connected through to one side of the inner wall of the seeder body 1. A tank cover 32 is threadedly connected to the outer surface of the inlet of the water tank 31. A water pump 33 is connected through to one side of the water tank 31. A spray frame 34 is fixedly connected to the outlet of the water pump 33. Before using the seeder body 1, the tank cover 32 is unscrewed, water is poured into the water tank 31, and then the tank cover 32 is closed. After the soil loosening device 2 works with the seeder body 1 to sow the seeds into the soil, the water pump 33 is started to pump the water in the water tank 31 into the interior of the spray frame 34, and then discharged from several outlets to irrigate the freshly sown seeds, provide them with moisture, promote seed germination, and improve seed survival rate.

[0046] Reference Figure 1-11 As shown in the figure, this embodiment discloses that filters 35 are fixedly connected to the inner walls of several outlets of the water spray frame 34. By setting the filters 35, the inner walls of the outlets of the water spray frame 34 can be protected, preventing soil from splashing into the inner walls of the water spray frame 34 during sowing and drilling, thus avoiding blockage at the outlets and extending its service life. Circular hole frames 36 are fixedly connected to the outer surfaces of both ends of the water spray frame 34, with one side of the circular hole frame 36 fixedly connected to one side of the seeder body 1. By setting the circular hole frames 36, the two ends of the water spray frame 34 can be supported and fixed, preventing wobbling during use and improving operational stability.

[0047] Reference Figure 1-11As shown, this embodiment discloses an auxiliary device 4 including a scraper 41 and a pad 46. A threaded rod 42 is fixedly connected to one side of the scraper 41, and a threaded hole block 43 is threadedly connected to the outer surface of the threaded rod 42. A rectangular groove 44 is opened on one side of the seeder body 1, and a rectangular hole 45 is opened on one side of the inner wall of the rectangular groove 44. The scraper 41 and the threaded rod 42 are slidably connected to the rectangular groove 44 and the rectangular hole 45, respectively. After placing the seeder body 1 into the planting field, the scraper 41 and threaded rod 42 can be manually slid down into the rectangular groove 44 and rectangular hole 45 to a certain position according to the height of the seeder from the ground. Then, the screw hole block 43 is turned to rotate it to a certain position so that one side of it abuts against one side of the seeder body 1, fixing the scraper 41 to the limiting post. After the seeder body 1 and the soil loosening device 2 have finished sowing the seeds, the scraper 41 will move along with the seeder body 1 during the driving process, scraping the drilled soil to level it. This can cover the sown seeds, improve sowing efficiency, and facilitate the use of the seeder body 1.

[0048] Reference Figure 1-11 As shown, this embodiment discloses a pad 46 sleeved on the outer surface of the threaded rod 42, with the pad 46 positioned between the threaded hole block 43 and one side of the seeder body 1. By providing the pad 46, the contact area between the threaded hole block 43 and the seeder body 1 can be increased, making it more secure when fixing the scraper 41.

[0049] The working principle is as follows: When using the seeder body 1 to sow seeds during forestry production, before using the seeder body 1, first unscrew the box cover 32, pour water into the water tank 31, and then close the box cover 32. At the same time, depending on the height of the seeder from the ground, manually slide the scraper 41 and the threaded rod 42 downwards in the rectangular groove 44 and the rectangular hole 45 to a certain position, and then turn the screw hole block 43 to rotate it to a certain position so that one side of it abuts against one side of the seeder body 1. Fix the scraper 41 to the limiting post so that the bottom of the scraper 41 abuts against the ground. When sowing, the seeds are put into the feed hopper 7, and then the seeds fall into the sowing groove 11 on the sowing roller 8 through the outlet of the feed hopper 7. At this time, start the drive motor 9 to drive the seeder. The seed roller 8 rotates within the inner walls of the seeder body 1 and the circular frame 6. Simultaneously, the operator holds the push rod 5 and propels the seeder body 1 across the planting field. The outer surface of the seed roller 8 is tightly pressed against the inner wall of the circular frame 6, thus the number of seeds falling into the seed trough 11 is fixed. When the seed roller 8 rotates, it causes the seeds in the seed trough 11 to move along the inner wall of the circular frame 6 to a certain position, where they fall into the guide pipe 21. The seeds then flow along the guide pipe 21 between the round rod 26 and the two drill blocks 213. At this point, the dual-shaft motor 216 on the fixed frame 217 is activated, driving the first gear 218 to rotate. This causes one of the gear ring blocks 28 to rotate within the inner wall of the support 215 and on the outer surface of the round rod 26, and also drives the circular ring block 27. Two U-shaped blocks 210, two rotating blocks 211, and two drill blocks 213 rotate. Driven by the second belt 214, several pairs of drill blocks 213 rotate. Simultaneously, connected by the second telescopic rod 225, the grooved ring frame 22, the winding roller 23, and the pull rope 25 also rotate. At this time, the other output end of the dual-axis motor 216 is simultaneously activated, causing the first telescopic rod 219 and the second gear 220 to rotate on the ring frame 6. This causes two third gears 221 to rotate in the same direction on the outer surface of the ring frame 6. Driven by the third belt 222, two reciprocating screws 223 rotate on the ring frame 6, causing their supports 215 to move downwards through the sliding holes 224 on the reciprocating screws 223. The movement causes the drill block 213 and the ring block 27 to slide downwards on the outer surface of the guide pipe 21 via the round rod 26. This downward movement and rotation of the drill block 213 and the ring block 27 loosens the soil in the sown field, breaking up harder soil and making it softer. As the drill block 213, the ring block 27, and the round rod 26 move downwards, they pull the first telescopic rod 219 and the second telescopic rod 225 apart. Simultaneously, one end of the pull rope 25 is continuously unwound on the winding roller 23, causing the first torsion spring 24 to deform. When the pull rope 25 is unwound to a certain position, the other end pulls one end of the drill block 213, causing it to rotate within the U-shaped block 210 via the rotating block 211, thus deforming the second torsion spring 212.The other end of the drill is opened to sow the seeds into the drilled soil. When the reciprocating screw 223 drives the support 215 upward, the drill block 213 will return to its original position and close under the reset action of the second torsion spring 212. At the same time, the first torsion spring 24 will drive the winding rod to return to its original position and re-wrap one end of the pull rope 25, making it easy to continue the operation for the next sowing. This operation can reduce the hardness of the sowing soil, making the seeder body 1 adaptable to different planting environments, improving its adaptability, and ensuring that the planting depth of each seed is consistent, thus improving the seed survival rate. At this time, the water pump 33 is started to draw water from the water tank 31 into the interior of the water spray frame 34, and then discharge it from several outlets to irrigate the freshly sown seeds, providing them with moisture, promoting seed germination, and improving seed survival rate. After the seeder body 1 and the soil loosening device 2 have finished sowing the seeds, the scraper 41 will move along with the seeder body 1 during its movement to level the drilled soil, cover the sown seeds, improve sowing efficiency, and facilitate the use of the seeder body 1. ,
