Description

Technical Field

[0001] This invention relates to the field of seed tray production technology, specifically a pneumatic roller-type seed tray sowing production line. Background Technology

[0002] Plug seedling technology has many significant advantages. First, it simplifies the seedling process, saves labor and effort, and greatly improves seedling efficiency. Second, this technology can save energy, seeds, and seedling space, reducing production costs. Third, plug seedlings have strong disaster resistance and produce high-quality seedlings, enabling the cultivation of healthy, disease-free, and robust seedlings of the appropriate age. In addition, the seedling cycle is short and the cost is low. Finally, plug seedlings have intact root systems, are not prone to falling apart, are suitable for long-distance transportation, and are conducive to commercial promotion. These advantages make plug seedling technology an important development direction for new vegetable seedling technologies.

[0003] In existing technologies, the production of seed trays for forest tree breeding and seedling cultivation often involves mixing soil and fertilizer on a production line and then covering the top of the seed tray with the mixed soil. While this method enables rapid production of seed trays, it cannot precisely control the amount of fertilizer in the soil of each seeding trough. If the amount is too small, the seedlings cannot grow quickly, while if there is too much fertilizer, the seeds may come into contact with the fertilizer after germination, leading to seedling burn. Therefore, we have introduced a pneumatic roller-type seed tray sowing production line. Summary of the Invention

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-8 The present invention provides a technical solution:

[0028] Example 1:

[0029] A pneumatic roller-type tray seeding production line includes a connecting frame 1. A conveyor belt 11 is located inside the connecting frame 1. The surface of the conveyor belt 11 has several holes for soil passage. A filling mechanism is located on the upper side of the conveyor belt 11 for storing soil. The filling mechanism is connected to the connecting frame 1. Two connecting frames 14 are fixedly connected to the upper end of the connecting frame 1. A connecting shaft 21 is movably connected between the two connecting frames 14. A connecting plate 22 is fixedly sleeved on the outer side of the connecting shaft 21. The outer side of the connecting plate 22 has an opening. An elastic box 9 is provided on the outside. The elastic box 9 is made of elastic material to prevent damage to the seeding tray when it comes into contact with the seeding tray. Both ends of the elastic box 9 are fixedly connected to circular plates 20. Both circular plates 20 are movably connected to the outside of the connecting shaft 21. One of the circular plates 20 is tightly fitted to the connecting plate 22. The elastic box 9 is provided with several liquid storage mechanisms. The liquid storage mechanisms are used to store nutrient solution and transport the nutrient solution to the soil in the seeding tray. One end of the liquid storage mechanism passes through the circular plate 20 and is connected to the external environment.

[0030] Several elastic pressure rings 16 are fixedly connected to the outside of the elastic box 9. The elastic pressure rings 16 are used to press the soil in the seeding tray to form the seeding trough. The elastic pressure rings 16 are connected to the liquid storage mechanism. A first guide pipe 26 and a second guide pipe 23 are fixedly connected to the outside of the connecting plate 22. The first guide pipe 26 is used to connect to the external air supply equipment. The second guide pipe 23 is used to guide the nutrient solution. Several infusion pipes 24 are provided inside the elastic box 9. The infusion pipes 24 are connected to the corresponding liquid storage mechanism. One end of the infusion pipe 24 is fixedly connected to a circular plate 20 and passes through the circular plate 20.

[0031] Several positioning rods 13 are fixedly connected to the outside of the conveyor belt 11. The positioning rods 13 are used to position the seeding trays. Two sensors 4 are provided on the inside of the connecting frame 1. In actual use, laser sensors of appropriate size and model can be selected for use. An extension bucket 6 is fixedly connected to one end of the connecting frame 1. The extension bucket 6 is used to store the produced seeding trays. A storage mechanism is provided at the upper end of the connecting frame 1. The storage mechanism is used to store nutrient solution.

[0032] Example 2:

[0033] Based on Example 1, in order to inject nutrient solution into the soil of the seeding tray while the elastic pressure ring 16 is pressing the seeding trough, the filling mechanism includes a hopper 10. The hopper 10 is fixedly connected to the upper end of the connecting frame 1. Several through slots are opened at the lower end of the hopper 10. A spiral conveying rod 12 is movably connected inside the hopper 10. A first motor 2 is fixedly connected to the outside of the hopper 10. The output end of the first motor 2 is fixedly connected to the spiral conveying rod 12. When the soil is filled into the hopper 10, when the positioning rod 13 moves to the position of the sensor 4 below the hopper 10, the first motor 2 located outside the hopper 10 will start. The first motor 2 drives the spiral conveying rod 12 to rotate, so that the soil in the hopper 10 falls into the soil above the seeding tray through the several through slots below the hopper 10.

[0034] The liquid storage mechanism includes a connecting rod 33, which is fixedly connected between two circular plates 20. Several liquid storage tanks 28 are fixedly connected to the outside of the connecting rod 33. A first liquid guiding cavity 32 is formed inside the connecting rod 33, and the first liquid guiding cavity 32 communicates with the several liquid storage tanks 28. A second liquid guiding cavity 15 is also formed inside the connecting rod 33, and the second liquid guiding cavity 15 communicates with the first liquid guiding cavity 32 through a connecting pipe 27. One end of the second liquid guiding cavity 15 extends into a circular plate 20. The end of the liquid storage tank 28 away from the connecting rod 33 is fixed. A liquid guide pipe 35 is fixedly connected. The end of the liquid guide pipe 35 away from the liquid storage tank 28 is connected to the elastic pressure ring 16. When the elastic box 9 drives the second liquid guide chamber 15 to rotate to the position of the first guide pipe 26, the corresponding elastic pressure ring 16 will rotate to the lowest side and be pressed into the soil. Since the first guide pipe 26 is connected to the external gas supply equipment, the gas will enter the second liquid guide chamber 15 through the first guide pipe 26. The gas entering the second liquid guide chamber 15 will push the baffle 31 to move.

[0035] A T-shaped piston 30 is movably connected inside the liquid storage tank 28. A return spring 29 is fixedly connected to the lower end of the T-shaped piston 30. The lower end of the return spring 29 is fixedly connected to the inner side of the liquid storage tank 28. A guide groove 36 is opened on the outer side of the liquid storage tank 28. A baffle 31 is slidably connected inside the second liquid guiding cavity 15. One end of the baffle 31 extends out of the second liquid guiding cavity 15 and passes through several guide grooves 36 in sequence. Two support springs 37 are fixedly connected to the outer side of the baffle 31. The end of the support spring 37 away from the baffle 31 Fixedly connected to the second liquid guiding chamber 15, the upper end of the baffle 31 is provided with several through holes 25. When the T-shaped piston 30 moves downward, its lower end will be inserted into the liquid guiding tube 35, so that when venting, the gas in the liquid storage tank 28 will be vented first, and after the T-shaped piston 30 no longer blocks the baffle 31, the baffle 31 will vent and return to the initial position. At the same time, the diameter of the T-shaped piston 30 inserted into the liquid guiding tube 35 is smaller than that of the liquid guiding tube 35 to prevent the liquid from being unable to be discharged through the liquid guiding tube 35.

[0036] A one-way valve 34 is fixedly connected to the outside of the liquid storage tank 28. The end of the one-way valve 34 away from the liquid storage tank 28 is connected to the infusion pipe 24. The one-way valve 34 allows liquid to enter into the liquid storage tank 28, but the liquid in the liquid storage tank 28 will not be discharged into the external environment through the one-way valve 34. A telescopic cylinder 8 is fixedly connected to the upper end of the connecting frame 14. The output end of the telescopic cylinder 8 extends into the inside of the connecting frame 14 and is fixedly connected to the connecting shaft 21. By opening the two telescopic cylinders 8 simultaneously, the connecting shaft 21 moves up and down along the connecting frame 14, thereby adjusting the distance between the elastic box 9 and the seeding tray.

[0037] A collection box 3 is movably connected to the lower end of the connecting frame 1. The collection box 3 is used to collect the soil falling from the conveyor belt 11. The storage mechanism includes a storage box 7, which is fixedly connected to the upper end of the connecting frame 1. A circulation pump 5 is fixedly connected to one end of the storage box 7. The input end of the circulation pump 5 extends into the storage box 7, and the output end is fixedly connected to the second guide pipe 23.

[0038] A connecting motor 18 is fixedly connected to the outside of the connecting shaft 21. A transmission gear 17 is fixedly connected to the output end of the connecting motor 18. The transmission gear 17 meshes with a gear ring 19. The gear ring 19 is fixedly connected to a circular plate 20.

[0039] Working principle: When using seeding trays for forest tree breeding, seedling cultivation, and seedling cultivation, the seeding tray is placed above the conveyor belt 11 and in contact with the positioning rod 13. By turning on the conveyor belt 11, the seeding tray is moved to fill the hopper 10 with soil. When the positioning rod 13 moves to the position of the sensor 4 below the hopper 10, the first motor 2 located outside the hopper 10 will start. The first motor 2 drives the spiral conveyor rod 12 to rotate, so that the soil in the hopper 10 falls into the seeding tray through several channels below the hopper 10. When the seeding tray passes below the scraper 38, the excess soil above the seeding tray is scraped off as the conveyor belt 11 moves the seeding tray.

[0040] When the seeding tray passes the sensor 4 and no longer obstructs it, the first motor 2 will stop rotating. When the seeding tray containing soil moves to the position of the sensor 4 located below the elastic box 9, the connecting motor 18 will start and drive the transmission gear 17 connected to its output end to rotate. Since the transmission gear 17 meshes with the gear ring 19, the elastic box 9 will rotate along the direction of the conveyor belt 11 during the rotation of the transmission gear 17. When the elastic box 9 drives the second liquid guiding chamber 15 to rotate to the position of the first guide pipe 26, the corresponding elastic pressure ring 16 will rotate to the bottom and be pressed into the soil. Since the first guide pipe 26 is connected to the external air supply equipment, the gas will enter the second liquid guiding chamber 15 through the first guide pipe 26. The gas entering the second liquid guiding chamber 15 will push the baffle 31 to move. When the baffle 31 cannot move, the through hole 25 in the baffle 31 will be aligned with the liquid guiding pipe 35.

[0041] At the same time, the baffle 31 will remove the obstruction to the connecting pipe 27. At this time, the gas entering the second liquid guiding chamber 15 will enter the first liquid guiding chamber 32 through the connecting pipe 27. The gas entering the first liquid guiding chamber 32 will enter several liquid storage tanks 28 in sequence. At this time, the T-shaped piston 30 will be pushed by the gas to move. The movement of the T-shaped piston 30 will push the nutrient solution in the liquid storage tank 28 into the liquid guiding pipe 35. Then, it will be injected into the soil of the seeding tray through the elastic pressure ring 16. The elastic pressure ring 16 will inject the nutrient solution into the soil while pressing the seeding hole.

[0042] When the nutrient solution storage tank 28 rotates to the opening position of the connecting plate 22, the corresponding second liquid guiding chamber 15 will also move to that position. At this time, under the elastic force of the return spring 29, the T-shaped piston 30 will move upward, and the gas in the storage tank 28 will be discharged into the external environment through the second liquid guiding chamber 15. When the lower end of the T-shaped piston 30 moves out of the liquid guiding pipe 35 and the through hole 25, the baffle 31 will return to the initial position under the elastic force of the support spring 37, and at the same time push the gas in the second liquid guiding chamber 15 into the external environment.

[0043] When the infusion tube 24 connected to the storage tank 28 of the exhaust gas moves to the position of the second guide tube 23, the nutrient solution in the storage tank 7 can be drawn into the second guide tube 23 by the circulation pump 5. The liquid entering the second guide tube 23 will enter the infusion tube 24, and then the nutrient solution will enter the storage tank 28 through several one-way valves 34. Since the baffle 31 will block the through hole 25, the guide tube 35 and the outlet of the storage tank 28 after returning to the initial position, the nutrient solution will be stored in the storage tank 28.

[0044] Several elastic pressure rings 16 set on the outside of the elastic box 9 press the soil in the seeding hole in sequence and inject nutrient solution. When the seeding hole no longer blocks the sensor 4 on the lower side of the elastic box 9, the connecting motor 18 and the circulation pump 5 are turned off, and the external air supply equipment stops. Then the seeding hole is transported by the conveyor belt 11 to the top of the extension bucket 6.
