Description

Technical Field

[0001] The invention relates to an agricultural device, in particular to an agricultural tomato seedling raising and sowing device. Background Art

[0002] As living conditions in my country gradually improve, the demand for vegetables and fruits is also increasing. Tomatoes are rich in carbohydrates, vitamins, carotene, and other nutrients. They have a sweet and sour taste, clear away heat and relieve summer heat, and can prevent a variety of diseases. They are deeply loved by consumers and have a huge market demand for tomatoes. Tomatoes are annual herbs, and farmers need to spend a lot of time each year to raise and sow tomato seedlings. Traditional tomato seedling and sowing is done entirely manually. First, use a shovel to dig a small hole about 5 cm deep in the ground, then sow the appropriate amount of tomato seeds, and finally backfill the excavated soil. This not only wastes a lot of manpower and time, resulting in low sowing efficiency, but the long sowing operation also places a huge burden on farmers' health.

[0003] Existing automated seeding systems typically use steel pipes or solid columns to drill holes in the soil. Steel pipes, with their tapered lower ends, prevent soil from draining easily after insertion. Solid columns compact the soil at the bottom of the hole, affecting its fluffiness at the seeding site. Furthermore, during the soil-covering process, rear wheels are often used to compact the pit and backfill the soil. This backfill is often not the same soil as that excavated, affecting the flatness of the soil. Summary of the Invention

[0006] As an improvement, a cone portion is formed at the lower end of the excavator, and a sealing plate is rotatably provided at the lower opening of the cone portion. The sealing plate is sealed at the lower opening by a spring. The fixed rod is a hollow structure, and a push rod is slidably provided inside the fixed rod. The push rod and the lower opening are arranged opposite to each other, and a feeding air pipe is provided inside the push rod, which is connected to the blowing pump.

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 6As shown, the agricultural tomato seedling raising and sowing device in this embodiment includes a bracket 1, a driving motor 3, a connecting shaft 31, a rotating wheel 32, a connecting rod 33, a rack 34, a sowing unit 2, a feeding mechanism 4 and an air pump.

[0018] Among them, a roller 13 is provided at the bottom of the bracket 1, and a plurality of sowing units 2 are provided on the bracket 1. The bracket 1 includes an upper support plate 11 and a lower support plate 12. The sowing unit 2 includes a fixed rod 21 fixedly arranged on the upper support plate 11, and a fixed bevel gear 23 is provided at the lower end of the fixed rod 21. A rotating shaft 22 is provided on the outer sleeve of the fixed rod 21, and a digging barrel 25 is provided on the outer sleeve of the rotating shaft 22. The digging barrel 25 is rotatably arranged on the lower support plate 12, and a spiral groove 252 is formed on the outer wall of the digging barrel 25. A soil-scraping tooth 253 is formed on the outer wall of the digging barrel 25 between adjacent spiral grooves 252. A transmission connection is provided between the digging barrel 25 and the rotating shaft 22, and a transmission bevel gear 24 meshing with the fixed bevel gear 23 is provided on the outer wall of the rotating shaft 22. A transmission column 241 is eccentrically provided on the outer end surface of the transmission bevel gear 24. An annular guide rail 251 is formed on the inner side wall of 25, and the transmission column 241 is limited to the annular guide rail 251. At the same time, in order to facilitate the transmission column 241 to roll in the annular guide rail 251 in the excavator tube 25, a rolling bearing can be sleeved on the transmission column 241, and the rolling bearing is limited to the annular guide rail 251; a rotating gear 27 is provided on the rotating shaft 22, and columns 28 are provided on both sides of the rotating gear 27 on the lower support plate 12. A transmission gear 281 meshing with the rotating gear 27 is provided at the upper end of the column 28, and a first bevel gear 283 is provided at the lower end of the column 28. A horizontal column 285 is horizontally arranged at the position corresponding to each column 28 on the lower support plate 12, and a second bevel gear 284 meshing with the first bevel gear 283 is provided on the horizontal column 285, and a covering plate 282 is provided on the horizontal column 285. When the digging barrel 25 is driven to rotate, the rotating shaft 22 also drives the transmission bevel gear 24 to rotate along the fixed bevel gear 23, and the transmission column 231 on the transmission bevel gear 23 can also drive the digging barrel 25 to slide up and down. In this way, when the digging barrel 25 is digging the pit, the digging barrel 25 moves downward while the digging barrel 25 can also rotate. As the digging barrel 25 rotates, the soil located directly below the digging barrel 25 can be discharged to the outer edge of the pit opening along the spiral groove 252 on the outer wall of the digging barrel 25. During the entire digging process, the digging barrel 25 does not generate a large pressure on the soil at the bottom of the pit, thereby preventing the soil in the pit from being compacted. When the digging barrel 25 is withdrawn in the reverse direction, by designing the gear parameters between the rotating gear 27 and the transmission gear 281 and between the first bevel gear 283 and the second bevel gear 284, it can be ensured that the two covering plates 282 swing inward, and most of the soil just excavated is filled back into the pit. In this way, the filling action can be completed synchronously.

[0019] Furthermore, a cone is formed at the lower end of the digging barrel 25, and a sealing plate is rotatably provided at the lower opening of the cone. The sealing plate is sealed at the lower opening by a spring. The fixed rod 21 is a hollow structure, and a push rod 26 is slidably provided inside the fixed rod 21. The push rod 26 and the lower opening are arranged opposite each other. A feeding air pipe is provided inside the push rod 26, and the feeding air pipe is connected to the air pump. When the digging barrel 25 is digging downward, the sealing plate can block the lower opening to prevent soil from entering the digging barrel 25. At the same time, when the digging barrel 25 reaches the bottom of the pit and begins to move upward, the push rod 26 can push the sealing plate open, and the air pump can blow the seeds into the pit. As the air flows, the soil deposited on the inner wall of the bottom of the digging barrel 25 will be blown away during each sowing process.

[0020] In addition, in the embodiment of the present invention, in order to realize the synchronous driving of multiple sowing units 2, as shown in FIG. Figure 3 As shown, a driving motor 3 is provided on one side of the lower support plate 12, and the output end of the driving motor 3 is connected to a connecting shaft 31, and a plurality of rotating wheels 32 are arranged at intervals on the connecting shaft 31, and a connecting rod 33 is eccentrically hingedly provided on the rotating wheel 32. A rack 34 is slidingly provided on the lower support plate 12 corresponding to each rotating wheel 32, and the connecting rod 33 and the rack 34 are hingedly connected to each other. A plurality of sowing units 2 are arranged at intervals along the length direction of the rack 34, and the rotating gear 27 of each sowing unit 2 is meshed with the rack 34. In this way, as the driving motor 2 rotates, the driving motor 2 can drive the connecting shaft 21 to rotate, and the connecting shaft 21 drives each wheel 32 to rotate. The wheel 32, the connecting rod 33 and the rack 34 form a crank-connecting rod mechanism, the wheel 32 is equivalent to the crank, and the rack 34 is equivalent to the slider structure. In this way, the rotation of the wheel 32 can drive the rack 34 to move back and forth, and the back and forth sliding of the rack 34 can drive the positive and negative rotation of the rotating gear 27. Specifically, when the rack 34 slides forward, the rotating gear 27 rotates clockwise, and the digging barrel 25 moves downward while rotating clockwise, which is the action of the digging barrel 25 digging a hole; when the rack 34 moves to the front end and starts to slide in the opposite direction, at this time, the corresponding digging barrel 25 also begins to prepare to reversely exit the pit, and the air pump can blow the seeds into the bottom of the pit.

[0021] In addition, in order to facilitate the discharge of seeds, a discharge mechanism 4 is provided on the upper support plate 11. Figure 6As shown, the discharge mechanism 4 includes a distribution plate 41, on which a plurality of filling holes 411 are evenly distributed in a circumferential direction. A vertically arranged feeding channel 43 is provided on one side of the distribution plate 41, and a conveyor belt 44 is provided in the feeding channel 43. The conveyor belt 44 is provided with separators 441 arranged at intervals. A group of thumbwheels 42 for feeding the seeds 5 in the filling holes 411 into the feeding channel 43 one by one are provided between the distribution plate 41 and the upper end of the feeding channel 43. A discharge port 45 is provided below the feeding channel 43, and the discharge port 45 is connected to the feeding air pipe. A blocking wheel is rotatably provided at the discharge port 45, and the blocking wheel is provided with blocking blades for separating the discharge port 45 of the feeding channel 43. The distribution plate 41 rotates to drop each seed 5 into the corresponding filling hole 411. The rotation of a set of dial wheels 42 can sequentially drop the seeds 5 in the filling hole 411 between two adjacent separators 441 on the conveyor belt 44. Along with the conveying action of the conveyor belt 44, the seeds 5 are transported to the discharge port 45 and eventually fall into the feeding air pipe. Under the action of the air pump, they fall into the earth pit. Among them, the blocking blades realize the sequential opening and closing operation of the discharge port 45 as the blocking wheel rotates. When opened, it can be used for dropping materials. When closed, the air pump can blow air into the feeding air pipe to enhance the power of the air flow and avoid affecting the discharge mechanism 4.

[0022] In summary, during the movement and sowing process of the bracket 1, the driving motor 3 drives the connecting shaft 31 to rotate, and the connecting shaft 31 can drive each rotating wheel 32 to rotate. The rotating wheel 32 drives the corresponding rack 34 to move back and forth through the connecting rod 33, so that the various rotating gears 27 meshing with the same rack 34 rotate back and forth in positive and negative directions, thereby driving each sowing unit 2 to move, wherein, while the rotating gear 27 rotates, the rotating gear 27 drives the digging barrel 25 to rotate through the rotating shaft 22. At the same time, while the rotating shaft 22 rotates, the transmission bevel gear 24 on the rotating shaft 22 rotates around the fixed bevel gear 23 at the bottom of the fixed rod 21. During the movement of the transmission bevel gear 24, the transmission column 241 on the transmission bevel gear 24 drives the digging barrel 25 to slide up and down, so that the digging barrel 25 can be moved up and down. The barrel 25 moves up and down while rotating. When digging a hole, the barrel 25 rotates and moves downward at the same time. In this way, the soil that blocks the barrel 25 can be transported to the outside of the hole along the spiral groove 252 of the barrel 25, so that the soil at the bottom of the hole will not be compacted, thereby ensuring the quality of the hole. After digging, the air pump can blow the seeds into the hole. After that, the barrel 25 can exit in the opposite direction. When exiting, the rotating gear 27 drives the two transmission gears 281 to rotate, and through the first bevel gear 283 and the second bevel gear 284, the two covering plates 282 can swing with each other, so that the soil just dug out can be re-covered in the hole, so that the dug soil can be backfilled. The whole process can be completed by driving the motor 3 and the air pump, thereby greatly improving the sowing efficiency.
