Description

Technical Field

[0001] This invention relates to the technical field of seed-binding machines for seedling raising, and more specifically to a seed-binding machine for double-layer seedling raising paper. Background Technology

[0002] Following the publication of the applicant's patent application for a printing seeder, the production technology of raising seedlings on paper has gradually become widespread. More and more different plants are adopting printing seeding, and the variety of seeds available for printing seeding is increasing. This method also makes it more convenient for research centers to study various plants. In rice research, it is often necessary to plant different varieties of seeds in the same field and then analyze and select the best varieties based on the rice's performance. Currently, the printing seeding method involves directly and evenly attaching seeds to the seedling paper with adhesive. This leaves the seeds exposed, making them susceptible to falling off the paper during handling or sowing, or being eaten by rodents or birds after sowing. This not only reduces the number of seeds on the seedling paper, affecting yield values, but also leads to mixing of fallen seeds when different varieties are planted adjacently. Seeds located at the boundary of different varieties may also become indistinguishable after maturing, resulting in inaccurate experimental results and impacting overall experimental outcomes.

[0003] Currently, assembly line seed-binding machines cannot separate and fix small batches of seeds of various varieties onto seedling paper. Although the applicant's previous patent application, entitled "Printing Seeder Applicable to Various Seedling and Seedling Substrates," discloses a method for fixing various different varieties of seeds onto different seedling papers, its dispensing efficiency and seed-binding efficiency are relatively low.

[0004] In addition, the seeds currently fixed on the seedling raising paper are glued on. Since the seeds fixed on the paper are exposed, they may fall off the seedling raising paper and be lost during the later turnover planting process. When the paper is laid in the field for seedling raising, the probability of the seeds being eaten by rodents or birds in the field will also increase. All of these factors can lead to inaccurate experimental results or reduced yield in actual production. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a seed-binding machine for double-layer seedling paper, which can pre-fix seeds between the seedling paper and mark them. The seeds are placed in the middle of the corresponding seedling paper and are left with sufficient distance from the edge of the seedling paper. Moreover, it can also separate the seedlings planted in the experimental field from the surrounding seedlings, avoiding confusion and affecting the experimental results caused by the seedlings or rice areas corresponding to the seeds in adjacent closed unit areas mixing together.

[0006] The technical solution adopted in this invention is:

[0007] A seed-binding machine for double-layer seedling paper includes a frame. From one end of the frame to the other end, a seedling paper unwinding device A, a perforating roller A, a seedling paper conveyor belt, and a seedling paper winding device are sequentially arranged. The seedling paper conveyor belt conveys the seedling paper from the end where the seedling paper unwinding device A is located to the end where the seedling paper winding device is located.

The lifting adjustment frame is also equipped with a glue scraper that moves reciprocally along the horizontal direction within the area of ​​the printing screen. The lifting adjustment frame is fixedly connected to a vertically adjustable frame. The vertical frame is fixedly connected to the machine frame. The screen array A is within the range of motion of the glue scraper.

[0011] A further improvement of the present invention is that the scraping device includes a horizontally movable frame that reciprocates horizontally along the lifting adjustment frame.

Scraper A and scraper B are respectively arranged below the horizontal connecting plate and along the moving direction of the horizontally movable frame. Scraper A and scraper B are respectively connected vertically by their respective lifting cylinders B. The lifting cylinders B are fixed to the horizontal connecting plate. There is a gap between the bottom of scraper A, which moves downward to its maximum stroke, and the top surface of the printing screen, which moves downward to its maximum stroke. The bottom of scraper B, which moves downward to its maximum stroke, is flush with the top surface of the printing screen, which moves downward to its maximum stroke. The bottoms of both scraper A and scraper B, which move upward to their maximum stroke, are higher than the top surface of the printing screen, which moves upward to its maximum stroke.

[0012] A further improvement of the present invention is that a horizontal slide bar is horizontally arranged on the lifting adjustment frame along the moving direction of the horizontal moving frame, and the horizontal moving frame is driven by a horizontal moving cylinder to reciprocate along the horizontal slide bar.

[0013] A further improvement of the present invention is that the frame is fixedly connected to vertical rods on both sides corresponding to the lifting and adjusting frame, and the tops of the vertical rods are fixedly connected to each other by a horizontal longitudinal rod. The lifting and adjusting frame is provided with matching sliding sleeves on both sides corresponding to the vertical rods. An adjusting screw is also provided between the vertical rods.

After the adjusting screw passes upward through the horizontal longitudinal rod, a screwing device is fixedly connected to it. The adjusting screw is rotatably connected to the horizontal longitudinal rod. The lifting and adjusting frame is fixedly connected with a nut pair that matches the threaded connection of the adjusting screw.

[0014] A further improvement of the present invention is that a horizontal bar is fixed to the bottom of the horizontal frame, the front edge and the rear edge relative to the conveying direction of the seedling paper conveyor belt, respectively. When the printing screen moves downward to the maximum stroke, the bottom of the horizontal bar contacts the top surface of the seedling paper conveyor belt.

[0015] A further improvement of the present invention is that the seed-dispensing device includes a horizontal dispensing base plate fixedly connected to the top of the frame. A horizontal rotating plate is coaxially rotatably connected to the top of the horizontal dispensing base plate via a drive motor.

A dispensing through hole is provided on the side of the horizontal dispensing base plate directly above the seedling paper conveyor belt, penetrating the top and bottom of the horizontal dispensing base plate. The diameter of the dispensing through hole is greater than or equal to the bottom diameter of the seed placement hopper. When the adhesive dots on the seedling paper A unwound by the seedling paper unwinding device A are conveyed to the position of the dispensing through hole by the seedling paper conveyor belt, the dispensing through hole is located within the range of the adhesive dot array B formed by the wire mesh array B.

[0021] A further improvement of the present invention is that the pore density of the wire mesh array A is greater than the pore density of the wire mesh array B.

[0022] The beneficial effects of this invention are as follows:

[0023] First, the seed-binding machine for the double-layer seedling paper of the present invention can pre-fix the seeds between the seedling paper and mark them. The seeds are respectively placed in the middle part of the corresponding seedling paper and at a sufficient distance from the edge of the seedling paper. Moreover, it can also separate the seedlings planted in the experimental field from the surrounding seedlings, avoiding confusion and affecting the experimental results caused by the seedlings or rice areas corresponding to the seeds in adjacent closed unit areas mixing together.

[0025] Third, the seed-binding machine of the double-layer seedling paper of the present invention, through the action of the perforated roller, enables the seeds between the two layers of seedling paper to breathe with the outside, which facilitates the improvement of the germination rate.

[0026] Fourth, the seed-adhesive machine for the double-layer seedling paper of the present invention, through the action of the gluing device, can quickly and accurately apply glue to the seedling paper, thereby enabling the seedling paper to effectively adhere to the seed and facilitating the fixation of the two layers of seedling paper.

[0027] Fifth, the seed-binding machine of the double-layer seedling paper of the present invention, through the action of the seed-dropping device, can fix different varieties of seeds separately at different positions on the seedling paper, so that the seeds in a certain closed unit area of ​​the seedling paper are all of the same variety and will not be mixed with the seeds in other closed unit areas.

The bottom of the horizontal frame 22, the front edge and the rear edge relative to the conveying direction of the seedling paper conveyor belt 4 are respectively fixed with transverse horizontal bars 37. When the printing screen 21 moves downward to the maximum stroke, the bottom of the transverse horizontal bars 37 contacts the top surface of the seedling paper conveyor belt 4. The seed-dropping device 6 includes a horizontal material-dropping base plate 38 fixedly connected to the top of the frame 1. The top of the horizontal material-dropping base plate 38 is coaxially rotatably connected to a horizontal rotating plate 39 through a drive motor 41. The bottom surface of the horizontal rotating plate 39 is in contact with water. The top surface of the flat feeding substrate 38 is attached, and the drive motor 41 is fixedly connected to the bottom of the horizontal feeding substrate 38. Multiple seed placement hoppers 40 are evenly distributed along the top edge of the horizontal rotating plate 39. The bottom of the seed placement hopper 40 penetrates the horizontal rotating plate 39. The horizontal feeding substrate 38 is provided with a feeding through hole (not shown in the attached drawing) that penetrates the top and bottom of the horizontal feeding substrate 38 on one side directly above the seedling paper conveyor belt 4. The diameter of the feeding through hole is greater than or equal to the bottom diameter of the seed placement hopper 40. When the glue dots on the seedling paper A unwound by the seedling paper unwinding device A2 are conveyed to the position of the feeding through hole by the seedling paper conveyor belt 4, the feeding through hole is located within the range of the glue dot array B formed by the wire mesh array B23.The vibration device is fixedly installed on the frame 1 at a position between the top and bottom conveyor belts of the seedling paper conveyor belt 4, and correspondingly located directly below the material discharge hole; the two ends of the pressing roller 9 are connected to the connecting frames on both sides of the frame 1 by springs 44 with preload, and the restoring force of the springs 44 causes the pressing roller 9 to press and fix the seedling paper B unwound by the seedling paper unwinding device B7 to the seedling paper A that has been glued with seeds; the seedling paper marking device 10 is fixedly connected to the frame 1 by a fixed bracket 16, and the fixed bracket 16 is also fixedly connected to... The machine includes an operation panel 17 with a seedling paper marking device 10; conveyor rollers A12, B14, and C18 are respectively located on the frame 1 between the seedling paper unwinding device A2 and the perforating roller A3, between the seedling paper unwinding device B7 and the perforating roller B8, and between the seedling paper marking device 10 and the seedling paper winding device 11; the axial positions of the rollers A19 of the perforating roller A3 and B42 of the perforating roller B8 are both located within the area enclosed by the wire mesh array A24; the pore density of the wire mesh array A24 is greater than that of the wire mesh array B23.

[0035] In use, different varieties of seeds for seedling cultivation are placed sequentially in the seed placement hopper 40. Then, the end of the seedling paper A, wound by the seedling paper unwinding device A2, first passes around the conveyor roller A12, then between the perforating roller A3 and the pad roller A13, and contacts the seedling paper conveyor belt 4. Afterward, it passes under the gluing device 5, under the seed dropping device 6, under the seedling paper unwinding device B7, and under the conveyor roller B14. It is then pressed together with the seedling paper B unwound by the seedling paper unwinding device B7 (which has passed over the conveyor roller B14) by the pressing roller 9. Finally, it passes around the conveyor roller C18 and is wound onto the seedling paper take-up roller 11. The seedling paper A unwound by the unwinding device A2 is conveyed around the conveyor roller A12 to the space between the perforating roller A3 and the pad roller A13. Multiple cuts A are evenly distributed on the surface of the seedling paper A after it passes through the roller cutter A19 of the perforating roller A3. When the seedling paper A is conveyed by the seedling paper conveyor belt 4 to the area below the gluing device 5, and the end of the seedling paper A extends beyond the gluing device 5 away from the unwinding device A2, the seedling paper conveyor belt 4 stops conveying. The printing screen 21 moves upward to its maximum stroke under the action of the lifting cylinder A25. Adhesive is placed on the top surface of the printing screen 21, and the lifting cylinder B29 of the scraper A26 drives the scraper A26 downward. Move to the maximum stroke position, then the horizontal movement drive cylinder drives the horizontal movement frame 30 and drives the scraper A26 to scrape the adhesive on the top surface of the printing screen 21 evenly and flat. Then, the lifting cylinder B29 of the scraper A26 drives the scraper A26 to move upward to the maximum stroke position. Then, the lifting cylinder A25 drives the horizontal frame 22 and the printing screen 21 downward to the horizontal bar 37 to press and fix the seedling paper A. Then, the lifting cylinder B29 of the scraper B27 drives the scraper B27 downward to the maximum stroke position, so that the bottom edge of the scraper B27 contacts the top surface of the printing screen 21. Then, the horizontal movement drive cylinder drives the horizontal movement frame 30 and drives the scraper A26 to move upward to the maximum stroke position. The movable scraper A26 scrapes the adhesive on the printing screen 21 through the screen mesh arrays A24 and B23, causing the adhesive on the printing screen 21 to fall downwards onto the seedling paper A, thereby forming adhesive dot arrays A and B respectively. Then, the lifting cylinder B29 of the scraper B27 drives the scraper B27 to move upwards to the maximum stroke position, and the lifting cylinder 29 of the scraper A26 drives the scraper A26 to move downwards to the maximum stroke position. The horizontal moving drive cylinder drives the horizontal moving frame 30 to move the scraper A26 again, and scrapes the adhesive on the printing screen 21 flat again.Next, the lifting cylinder A25 drives the horizontal frame 22 and the transverse horizontal bar 37 to move upward to their maximum stroke. The seedling paper conveyor belt 4 continues to convey the seedling paper A. When the adhesive dot array B of the seedling paper A is directly below the material discharge hole, the seedling paper conveyor belt 4 stops conveying again, and the drive motor 41 drives the horizontal rotating plate 39 to rotate around the axis until the seed placement hopper 40 containing the corresponding variety of seeds rotates to the position of the material discharge hole and stops, so that the corresponding variety of seeds fall down along the seed placement hopper 40 and the material discharge hole into the center of the area of ​​adhesive dot array B formed by the wire mesh array B23 below; and through the vibration of the vibration device, the seeds can be evenly adhered by the adhesive dot array formed by the wire mesh array B23. The seedling paper A, after being adhered, continues to be conveyed to the pressing roller 9 under the conveyor belt 4. At the same time, the seedling paper B of the seedling paper unwinding device B7 passes around the conveyor roller B14. After passing between the perforating roller B8 and the pad roller B15, seedling paper B is laid on the top surface of seedling paper A, which is conveyed by the seedling paper conveyor belt 4. When seedling paper B and seedling paper A pass together through the pressing roller 9, the top surface of seedling paper A still has the glue dot array A formed by the screen mesh array A24. Seedling paper B is bonded and fixed to seedling paper A by the glue dot array A. The position corresponding to the glue dot array A is the bonding point between seedling paper A and seedling paper B. After passing through the pressing roller 9, seedling paper A and seedling paper B are conveyed by the seedling paper conveyor belt 4 to the area directly below the seedling paper marking device 10. The seedling paper marking device 10 marks the seeds of the corresponding varieties between seedling paper A and seedling paper B. The marking content can be edited and modified through the operation panel 17. After passing through the seedling paper marking device 10, seedling paper A and seedling paper B pass around the conveyor roller C18 and are finally wound around the seedling paper winding device 11.

[0036] To ensure that the seeds, which pass sequentially through the seed placement hopper 40 and the discharge through-hole into the adhesive dot array B, do not jump out of the adhesive dot array B during vibration, an annular base frame (not shown in the attached drawings) can be fixed to the bottom of the horizontal discharge substrate 38. The discharge through-hole is located inside the annular base frame, and a matching annular lifting frame (not shown in the attached drawings) is fitted and fixed to the outside of the annular base frame. The inner sidewall of the annular lifting frame is fitted to the outer sidewall of the annular base frame, and the annular lifting frame matches or corresponds to the edge of the adhesive dot array B in the area between the adhesive dot array B and the adhesive dot array A. The lifting frame is driven by a lifting cylinder C (not shown in the attached diagram) fixed to the bottom of the horizontal feeding base plate 38, which moves the annular lifting frame up and down relative to the annular base frame. The bottom edge of the annular base frame is higher than the top surface of the seedling paper conveyor belt 4. When the annular lifting frame moves upward to its maximum stroke, the bottom edge of the annular lifting frame is higher than the top surface of the seedling paper conveyor belt 4. When the annular lifting frame moves downward to its maximum stroke, the bottom of the annular lifting frame contacts the top surface of the seedling paper conveyor belt 4, and the top edge of the annular lifting frame is higher than the bottom edge of the annular base frame. In use, when the glue dot matrix B of the seedling paper A is located directly below the feeding through hole, and the seedling paper conveyor belt 4 stops conveying again, the lifting cylinder C drives the annular lifting frame downward to its maximum stroke; after the vibration device completes vibration, the lifting cylinder C drives the annular lifting frame upward to its maximum stroke.

[0037] When the seedling raising paper is finished and ready for seedling raising, unroll the seedling raising paper and use scissors or other methods to separate the area between the adhesive joints of two adjacent closed unit areas that are respectively fixed with seedling raising seeds, thereby separating a seed fixing area at the end of the seedling raising paper so that the seed can be raised; and before raising seedlings, you can check the relevant information such as the type of seed to be raised through the markings on the surface of the seedling raising paper B.
