Description

Technical Field

[0001] This invention relates to the field of seed sowing technology, and in particular to a novel seed printing and sowing device and its sowing method. Background Technology

[0002] To reduce the labor intensity of mulching cultivation, seed printers have been developed to ensure precise sowing spacing in research on wheat, corn, rice, and vegetables. In the breeding of new crop varieties, sowing in experimental plots is the most crucial step in the entire breeding experiment. Currently, most research institutions in China still use manual sowing, which is labor-intensive, has a high workload, and results in uneven sowing rates, directly affecting the effectiveness of the breeding experiment. The advent of seed tapes, using a printed sowing method, can improve sowing accuracy. However, due to the influence of terrain, even with seed tapes, sowing accuracy can be affected to some extent when encountering uneven ground. Summary of the Invention

[0009] Preferably, the film winding drive assembly includes film winding fixing plates fixed on both sides of the equipment frame. A guide roller, a power roller, and a driven roller are arranged between the two film winding fixing plates. The guide roller and the power roller are located on the same plane, with the guide roller located behind the power roller and the driven roller located below the power roller. The power roller is connected to the film winding roller via a roller shaft drive mechanism. The film roll fixed on the film winding roller passes around the guide roller from the rear side, is horizontally guided by the guide roller, passes around the power roller from the front side, is then laid downwards, passes around the driven roller from the rear side, and enters the dispensing machine, extending from below the dispensing roller of the dispensing machine.

[0010] Preferably, the dispensing machine includes a dispensing machine housing fixed to the top of the equipment frame, a dispensing motor set on the top of the dispensing machine housing, a first rotating shaft connected to the output end of the dispensing motor, transmission wheels set at both ends of the rotating shaft, and a rotating shaft connected at both ends to the corresponding transmission wheels through a dispensing transmission mechanism. Multiple sliding connecting blocks are fixed on the rotating shaft. A connecting shaft is set on one side of the rotating shaft. Dispensing wheels corresponding to the number of sliding connecting blocks are set on the connecting shaft. The wheel rod of the dispensing wheel is fixed to the sliding connecting block. Multiple needle tips are provided on the wheel surface of each dispensing wheel (22). A dispensing head is provided on the wheel rod of each dispensing wheel. The dispensing outlet of the dispensing head is in contact with the wheel surface of the dispensing wheel. The dispensing head and the dispensing motor are electrically connected to the controller.

[0011] Preferably, the rotating shaft is provided with two shafts, one upper and one lower, and the connecting shaft is positioned at a higher height than the lower rotating shaft.

[0012] Preferably, the film-stretching body includes film-stretching fixing frames fixed on both sides of the equipment frame, a film-stretching roller disposed between the two film-stretching fixing frames, a film-stretching fixing plate fixed on one of the film-stretching fixing frames, and a film-stretching motor fixed on the film-stretching fixing plate. The output end of the film-stretching motor is connected to the film-stretching roller, and the film-stretching motor is electrically connected to the controller.

[0013] Preferably, the film-pulling fixing frame is also fixed with a braking device for controlling the rotation speed of the film-pulling roller to control the film-winding speed and prevent the film from breaking.

[0014] Preferably, the bottom of the equipment frame is equipped with wheels and support legs, the top surface of the equipment frame is a stepped surface, the dispensing machine and the film winding transmission assembly are both located at a lower position on the top surface of the equipment frame, the seed sowing bin is located at a higher position on the top surface of the equipment frame, and the height of the film pulling and winding roller is flush with the higher part of the top surface of the equipment frame.

[0015] Preferably, the seed sowing bin includes a seed storage hopper, and the bottom of the seed storage hopper is provided with a straight-opening seed drop outlet.

[0016] A method for seeding using the aforementioned device specifically includes the following steps:

[0017] S1, set the seed sowing density and sowing location in the controller;

[0018] S2, the film exit end of the film roll is led out from the film roll roller, passes around the film roll transmission assembly and enters the dispensing machine, then passes under the dispensing wheel of the dispensing machine and under the seeding port of the seed sowing bin, passes around the film pulling and winding roller and then winds onto the film pulling roller.

[0019] S3, according to the set sowing position and sowing shape, rotate the corresponding dispensing wheel to the dispensing position;

[0020] S4. Simultaneously start the film stretching machine, film winding machine and dispensing machine. While the film is conveyed forward by the film winding machine and film stretching machine, the dispensing wheel of the dispensing machine rotates up and down under the drive of its dispensing transmission mechanism so that the needle tip on its wheel surface punctures the film and sticks the glue to the edge of the hole to form glue holes. As the film is conveyed forward, a glue hole array is formed on the film.

[0021] When the film with adhesive is conveyed to the bottom of the seed sowing chamber, the seeds are scattered from the seed drop outlet at the bottom of the seed sowing chamber onto the film and are stuck into the glue holes by the adhesive at the edge of the glue holes. The film with the seeds stuck to it continues to be conveyed forward and is then rolled up onto the film pulling roller.

[0022] During the film winding process, seeds that are not firmly stuck or not stuck fall into the seed recycling bin for recycling.

[0023] S5, remove the seed-coated film from the film-pulling roller and wait for sowing;

[0024] S6. When planting seeds, lay the rolled-up film with the seeds attached flat on the soil surface with the film facing up and the seeds facing down, so that the seeds are in contact with the soil. Cover the film with a thin layer of soil, and then water according to the seed growth requirements. Based on the phototropism of the seedlings, the seedlings will emerge from the adhesive holes of the film.

[0025] The beneficial effects of this invention are:

[0026] 1. This invention sets up a film rolling machine, a glue dispensing machine, a seed sowing bin, a film pulling machine, and a seed recycling bin on the equipment frame. During the film's movement, seeds can be stuck onto the film, and the seed-attached film is rolled up on the film pulling machine. During the film rolling process, any seeds that are not firmly attached will fall into the seed recycling bin for recycling. Thus, when sowing seeds, the seed-attached film can be directly laid flat on the soil.

[0027] 2. During the forward conveying process, the film of the present invention can be pressed and stretched by multiple rollers on the film winding machine and the film stretching machine to avoid wrinkles in the film, thereby effectively ensuring the accuracy of dispensing and seed adhesion, and thus improving the sowing accuracy.

[0028] 3. The present invention is equipped with traveling wheels and outriggers at the bottom of the equipment frame. When transportation is required, the outriggers can be retracted and the entire device can be transported to the designated location by the traveling wheels. After the device is transported to the location, the outriggers are lowered and the traveling wheels are retracted at the same time to effectively support the device. In addition, the outriggers are designed to be telescopic and adjustable in length, which can make the device adapt to uneven ground and various terrains, making the device more widely used.

[0029] 4. This invention achieves automatic adhesive printing by controlling the film rolling machine and the film stretching machine, thus realizing fully automatic adhesive bonding and fixing of seeds on the film. At the same time, it can also ensure the accuracy of the sowing position, reduce manpower consumption, save time and effort, and improve sowing efficiency. Attached Figure Description

[0046] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0047] This invention provides a novel seed printing and sowing device, comprising a frame 1, a film winding machine for fixing the film roll and conveying the film 8 forward, a dispensing machine 6 for dispensing adhesive onto the film 8 to form an adhesive array of a predetermined shape on the film 8, a seed sowing bin 7 for sowing seeds so that the seeds adhere to each dispensing point in the adhesive array, a film pulling machine for pulling the film 8 forward and rewinding the film with the seeds, a seed recovery bin 10 for collecting the seeds that are not firmly adhered during the film winding process of the film pulling machine, and a controller 27.

[0048] The equipment frame 1 is used to support and fix the film rolling machine, the glue dispensing machine 6, the seed sowing bin 7, the film pulling machine, the seed recycling bin 10, and the controller 27.

[0049] The bottom of the equipment frame 1 is equipped with multiple pairs of wheels 2 and support legs 3. The wheels 2 are foldable rollers, and the support legs 3 are shock-absorbing and adjustable in length to adapt to various terrains. Installing wheels 2 at the bottom of the equipment frame 1 facilitates the transportation of the entire device. The top surface of the equipment frame 1 is a stepped surface, with the front part of the top plate higher than the rear part.

[0050] The film winding machine includes a film winding body 4 located at the lower rear side of the equipment frame 1 and a film winding transmission assembly 5 located at the top rear side of the equipment frame 1. The glue dispensing machine 6 and the seed sowing bin 7 are both located at the top of the equipment frame 1, with the glue dispensing machine 6 located in front of the film winding transmission assembly 5 and the seed sowing bin 7 located in front of the glue dispensing machine 6. Specifically, the glue dispensing machine 6 and the film winding transmission assembly 5 are both located on the lower part of the top surface of the equipment frame 1, and the seed sowing bin 7 is located on the higher part of the top surface of the equipment frame 1.

[0051] The film roll body 4 includes film roll mounting plates 28 fixed on the lower left and right sides of the rear side of the equipment frame 1, a film roll bracket 29 fixed on one of the film roll mounting plates 28, and a film roll roller 16 disposed between the left and right film roll mounting plates 28. A film roll motor 30 is mounted on the film roll bracket 29. The output shaft of the film roll motor 30 is connected to the film roll roller 16. The film roll motor 30 is electrically connected to the controller 27.

[0052] The film winding transmission assembly 5 includes film winding fixing plates 14 fixed on both sides of the equipment frame 1. A guide roller 11, a power roller 12, and a driven roller 13 are arranged between the two film winding fixing plates 14. The guide roller 11 and the power roller 12 are arranged parallel to each other on the same plane, with the guide roller 11 positioned behind the power roller 12. The driven roller 13 is positioned below the power roller 12. The power roller 12 is connected to the film winding roller 16 via a roller shaft transmission mechanism. Preferably, the driven roller 13 is located between the guide roller 11 and the power roller 12, and is positioned close to the power roller 12.

[0053] The film 8, fixed on the film roll 16, passes around the guide roller 11 from the rear side. After being horizontally guided by the guide roller 11, it passes around the power roller 12 from the front side. Then it is laid downward and passes around the driven roller 13 from the rear side and enters the glue dispensing machine 6. After passing under the glue dispensing wheel of the glue dispensing machine 6 and under the seeding port of the seed sowing bin 7, it passes around the film pulling and winding roller 17 and is wound onto the film pulling body 9 to achieve winding.

[0054] The dispensing machine 6 includes a dispensing machine housing 18 fixed to the top of the equipment frame 1, a dispensing motor 26 mounted on the top of the dispensing machine housing 18, a first rotating shaft 25 connected to the output end of the dispensing motor 26, transmission wheels 24 mounted at both ends of the rotating shaft 25, and a rotating shaft 19 connected at both ends to the corresponding transmission wheels 24 via a dispensing transmission mechanism (not shown in the figure). Multiple sliding connecting blocks 21 are fixed on the rotating shaft 19. A connecting shaft 20 is provided on one side of the rotating shaft 19. Dispensing wheels 22 corresponding to the number of sliding connecting blocks 21 are mounted on the connecting shaft 20. The wheel rod 23 of the dispensing wheel 22 is fixed to the sliding connecting block 21. Each dispensing wheel 22 has a dispensing head on its wheel rod 23. The dispensing outlet of the dispensing head is in contact with the wheel surface of the dispensing wheel 22. The dispensing head and the dispensing motor 26 are both electrically connected to the controller 27.

[0055] In this embodiment, the rotating shaft 19 is provided with two shafts, one above the other, and the connecting shaft 20 is positioned at a higher height than the rotating shaft 19 located below it.

[0056] When the dispensing motor 26 is started, the dispensing motor 26 drives the first rotating shaft 25 to rotate. The first rotating shaft 25 drives the rotating shaft 19 to rotate through the dispensing transmission mechanism. When the rotating shaft 19 rotates, it drives the sliding connecting block 21 to rotate synchronously. Since the sliding connecting block 21 and the dispensing wheel 22 are fixed together, the rotation of the sliding connecting block 21 can drive the dispensing wheel 22 to rotate synchronously (that is, the dispensing wheel can flip up and down to achieve the dispensing action). While the dispensing wheel 22 flips up and down, it moves forward with the film 8 to form a glue array of a set shape on the film 8.

[0057] Since the dispensing roller 22 has needle tips on its surface, when the dispensing roller 22 is flipped down to contact the film surface, the needle tips on its surface will pierce the film surface. At this time, the dispensing head will dispense glue, which can stick to the edge of the hole in the film to form a glue hole.

[0058] When the adhesive-coated film 8 moves toward the seed sowing chamber 7, the seeds in the seed storage hopper 15 of the seed sowing chamber 7 fall onto the film 8 from the seed drop opening at its bottom. Some seeds will fall directly onto the surface of the film, but some seeds will fall into the glue holes and be stuck by the glue at the edge of the glue holes. The film 8 with the seeds stuck on it continues to move forward.

[0059] When dispensing is required, the dispensing roller 22 is lowered and placed on the dispensing position so that it can contact the film. When dispensing is not required, the dispensing roller 22 is flipped up. The flipped-up dispensing roller 22 can rest on the rotating shaft 19 located above. The seed sowing density can be adjusted by adjusting the number of dispensing rollers located on the dispensing position and the interval between flipping the dispensing rollers up and down.

[0060] The seed sowing bin 7 includes a seed storage hopper 15, which is an open hopper with a straight-opening seed drop opening at the bottom.

[0061] The film stretching machine includes a film stretching and winding roller 17 located on the front side of the equipment frame 1 and in front of the seed sowing bin 7, and a film stretching body 9 located on the lower part of the front side of the equipment frame 1. The seed recovery bin 10 is located below the film stretching body 9.

[0062] The film winding roller 17 is set at the same height as the higher part of the top surface of the equipment frame 1.

[0063] The film-pulling body 9 includes film-pulling fixing frames 30 fixed on both sides of the equipment frame 1, film-pulling rollers 32 disposed between the two film-pulling fixing frames 30, film-pulling fixing plates 31 fixed on one of the film-pulling fixing frames 30, and film-pulling motors 33 fixed on the film-pulling fixing plates 31. The output end of the film-pulling motor 33 is connected to the film-pulling rollers 32, and the film-pulling motor 33 is electrically connected to the controller 27.

[0064] After the seed-adhered film 8 passes over the film-pulling and winding roller 17, it is wound downwards onto the film-pulling roller 32. As the film-pulling roller 32 rotates, the seed-adhered film 8 is wound onto the film-pulling roller 32, thus achieving the winding of the film 8. During the winding process, seeds that are not firmly adhered or do not fall into the adhesive area will fall into the seed recycling bin 10, thus achieving seed recycling and avoiding seed waste. The recycled seeds can be reused.

[0065] In this embodiment, the film 8 is a fully biodegradable PBAT mulch film with a thickness of 8-10 μm.

[0066] Preferably, the film-pulling fixing frame 30 is also fixed with a braking device 34 for controlling the rotation speed of the film-pulling roller 32 to control the film-winding speed and prevent the film from breaking.

[0067] The present invention also provides a method for seeding using the aforementioned device, specifically comprising the following steps:

[0068] S1, set the seed sowing density, sowing location and sowing shape in the controller 27;

[0069] S2, the film exit end of the film roll is led out from the film roll roller 16, passes around the film roll transmission assembly 5 and enters the dispensing machine 6, then passes under the dispensing wheel of the dispensing machine 6 and under the seeding port of the seed sowing bin 7, passes around the film pulling and winding roller 17 and then winds onto the film pulling roller 32.

[0070] S3, according to the set sowing position and sowing shape, rotate the corresponding dispensing wheel 22 to the dispensing position;

[0071] S4, simultaneously start the film stretching machine, film winding machine and dispensing machine 6. While the film 8 is conveyed forward by the film winding machine and film stretching machine, the dispensing wheel of the dispensing machine 6 rotates up and down under the drive of its dispensing transmission mechanism so that the needle tip on its wheel surface punctures the film 8 and sticks the glue to the edge of the hole to form glue holes. As the film 8 is conveyed forward, a glue hole array is formed on the film 8.

[0072] When the film 8 with adhesive is conveyed to the bottom of the seed sowing chamber 7, the seeds are scattered from the seed drop outlet at the bottom of the seed sowing chamber 7 onto the film 8 and are stuck in the glue hole by the adhesive at the edge of the glue hole. The film with the seeds stuck to it continues to be conveyed forward and is then rolled up onto the film pulling roller 32.

[0073] During the film winding process, seeds that are not firmly stuck or not stuck fall into the seed recycling bin 10 for recycling.

[0074] S5, remove the film with seeds attached from the film pulling roller 32 and wait for sowing;

[0075] S6. When planting seeds, lay the rolled-up film with the seeds attached flat on the soil surface with the film facing up and the seeds facing down, so that the seeds are in contact with the soil. Cover the film with a thin layer of soil, and then water according to the seed growth requirements. Based on the phototropism of the seedlings, the seedlings will emerge from the adhesive holes of the film.

[0076] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

The output end of the film-pulling motor (33) is connected to the film-pulling rollers (32), and the film-pulling motor (33) is electrically connected to the controller (27).

5. The novel seed printing and sowing device according to claim 4, characterized in that, The film-pulling fixing frame (35) is also fixed with a braking device (34) for controlling the rotation speed of the film-pulling roller (32) to control the film-winding speed and prevent the film from being pulled apart.

6. The novel seed printing and sowing device according to claim 1, characterized in that, The bottom of the frame (1) of the equipment is provided with a walking wheel (2) and a support leg (3). The top surface of the equipment frame (1) is a stepped surface. The dispensing machine (6) and the film winding transmission assembly (5) are both located at the lower position of the top surface of the equipment frame (1). The seed sowing bin (7) is located at the higher position of the top surface of the equipment frame (1). The height of the film pulling and winding roller (17) is flush with the higher part of the top surface of the equipment frame (1).

7. The novel seed printing and sowing device according to claim 1, characterized in that, The seed sowing bin (7) includes a seed storage hopper (15), and the bottom of the seed storage hopper (15) is provided with a straight-opening seed drop port.

8. A method for seeding using the apparatus according to any one of claims 1-7, characterized in that, Specifically, the following steps are included: S1, set the seed sowing density and sowing location in the controller (27); S2, the film roll exit end is led out from the film roll roller (16), passes around the film roll transmission assembly (5) and enters the dispensing machine (6), then passes under the dispensing wheel of the dispensing machine (6) and under the seeding port of the seed sowing bin (7), passes around the film pulling and winding roller (17) and then winds onto the film pulling roller (32). S3, according to the set sowing position and sowing shape, rotate the corresponding dispensing wheel (22) to the dispensing position; S4, start the film stretching machine, film winding machine and dispensing machine (6) at the same time. The film (8) is conveyed forward under the action of the film winding machine and the film stretching machine. At the same time, the dispensing wheel of the dispensing machine (6) rotates up and down under the drive of its dispensing transmission mechanism so that the needle tip on its wheel surface punctures the film (8) and sticks the glue to the edge of the hole to form glue holes. As the film (8) is conveyed forward, a glue hole array is formed on the film (8). When the film (8) with adhesive is conveyed to the bottom of the seed sowing bin (7), the seeds are scattered from the seed drop opening at the bottom of the seed sowing bin (7) onto the film (8) and are stuck into the glue hole by the adhesive at the edge of the glue hole. The film with the seeds is conveyed forward and then rolled onto the film pulling roller (32). During the film winding process, seeds that are not firmly stuck or not stuck fall into the seed recycling bin (10) for recycling; S5, remove the film with seeds attached from the film pulling roller (32) and wait for sowing; S6. When planting seeds, lay the rolled-up film with the seeds attached flat on the soil surface with the film facing up and the seeds facing down, so that the seeds are in contact with the soil. Cover the film with a thin layer of soil, and then water according to the seed growth requirements. Based on the phototropism of the seedlings, the seedlings will emerge from the adhesive holes of the film.
