Description

Technical Field

[0001] The invention relates to the technical field of seedling raising equipment, and in particular to a precise seedling raising and efficient seeder. Background Art

[0002] The applicant has previously developed a patented device for a printing seeder, which is to apply glue dots to the corresponding positions on the seedling paper in advance, and then vibrate a sufficient amount of seeds on the straight surface, so that the positions on the seedling paper with glue dots can fix the seeds, and then roll up the seedling paper with fixed seeds, and when it is necessary to sow and raise seedlings, the seedling paper is unfolded to the field or cut and placed in the seedling tray. However, this printing seeder has the problems of low glue application efficiency and seed sticking efficiency, and the seeds fixed on the seedling paper are fixed to the surface of the seedling paper by glue, and the seeds are exposed to the outside. In the later turnover planting process, the seeds may fall off the seedling paper and be lost. When it is spread in the field to raise seedlings, it will also increase the probability of the seeds being eaten by rodents or birds in the field, thereby reducing the seedling success rate, and then leading to a reduction in the actual production output; if this seedling paper is used as a test field for scientific research, it will seriously affect the accuracy of the test results.

[0003] In order to solve the above problems, the applicant later developed a double-layer seedling paper seed sticking machine, applied for a patent and submitted a patent application. The principle is that after the above-mentioned seedling paper is used to stick the seeds, another layer of seedling paper is fixed on the end surface of the seedling paper where the seeds are pasted. After forming a double-layer seedling paper, the paper is rolled up, thereby solving the problem of seeds falling during the turnover process and preventing seeds from being exposed and eaten by birds and rodents during seedling raising.

[0004] However, in actual production, it is found that the traditional printing seeder and the double-layer seedling paper seed sticking machine both set glue dots at designated positions, and then place excess seeds on the seedling paper with glue dots and vibrate them so that the seeds at the glue dots are stuck and fixed by the glue dots. The problem this causes is that, in fact, only the glue dots are precisely positioned, while the mass of the seeds is relatively small. Therefore, during the vibration process, as long as any part of the seeds touches the glue dots, they will be stuck and fixed by the glue dots. This results in different numbers of seeds fixed by different glue dots. Some glue dots may only have 2 to 3 seeds fixed after vibration, while some may have 4 to 5 seeds fixed. This results in different amounts of seedlings at positions corresponding to different glue dots during the later stage of seedling raising. In addition, the tillering of rice seedlings will form a small patch of seedlings at the glue dots with more seeds. Moreover, when the number of seeds fixed by the glue dots is large, the amount of glue liquid that each seed at the position of the glue dots is exposed to is relatively small. During the turnover of the seedling paper, it is still Of course, some of the seeds at the glue point will no longer be fixed to the seedling raising paper and will be separated, which means that the single-layer seedling raising paper will still exist, resulting in a reduction in the actual production output, and the use of it for scientific research will still make the test results inaccurate; although the double-layer bottom seedling raising paper can still keep the seeds that are no longer fixed to the seedling raising paper between the double-layer seedling raising paper, and can still grow seedlings in the later stage, their positions are no longer fixed to the seedling raising paper, so the seedlings produced by the seedling raising paper will appear outside the regular seedling emergence position, and the double-layer seedling raising paper is only fixed by various glue points, that is, the rest of the positions between the double-layer seedling raising paper are not fixed and there are gaps, so the seeds that are no longer fixed to the glue points may still fall out from between the double-layer seedling raising paper. If the double-layer seedling raising paper is used for scientific research experiments, it will make it impossible to determine what kind of test seedlings are not in the regular seedling emergence position, resulting in inaccurate test results.

[0005] In addition, for scientific research experiments, the amount of seeds used for the experiment is very limited, and it is impossible to use sufficient or excessive test seeds on the seedling raising paper that has been glued and fixed by vibration so that each glue point is pasted with experimental seeds. Moreover, the existing equipment cannot guarantee that the distribution of the seeds pasted is exactly the same each time it produces and prepares the seedling raising paper with seeds pasted and fixed, especially for the seedling raising required by the experimental field of scientific research experiments. In order to ensure the accuracy of the growth condition conclusions obtained by the experiment, it is necessary to try to ensure the consistency of the types and distribution of the seed raising seeds in each control group. However, the traditional seedling raising paper production equipment can only produce one roll of seedling raising paper at a time, and the multiple rolls of different seedling raising paper produced by the same equipment cannot guarantee that the amount of seeds and the seed types at each place of the seed raising paper are the same. This will be because the consistency of the seed conditions is low and the accuracy of the other growth condition related conclusions cannot be guaranteed. Therefore, there is an urgent need for such a seedling raising paper production equipment that can produce multiple rolls of seedling raising paper at the same time and ensure that the corresponding seed types and distribution of each roll of seedling raising paper are consistent.

[0047] A supporting leg 50 is fixedly provided on the top of the frame 1 .

[0048] When the present application is used, the paper A51 unwound by the unwinding device A2 is sequentially conveyed in steps through the transition roller A12, the tension roller 14 and the transition roller B13, and then passes between the punching roller A3 and the punching plate A16, and the punching roller A3 presses holes evenly on the surface of the paper A51, and the paper A51 with holes pressed out continues to be conveyed forward in steps. When the paper A51 is conveyed in steps to the glue spraying area below the corresponding glue spraying head 4, when the paper A51 is in a paused state of stepping, the glue spraying head 4 sprays glue to the corresponding paper A51 to form a glue layer, and when the paper A51 is conveyed again, the glue spraying head 4 stops spraying glue; whenever the paper A51 is conveyed in steps to the paused state, the driving device A21 also drives the annular conveyor belt 19 to convey a group of seed placing cups to the seed placing station 2 3. At this time, the operator or the automatic seeding device places a certain amount of corresponding seeds in each seeding cup 20 of the seeding cup group located at the seeding station 23. At the same time, the seeding cup group that has been located at the seeding station 23 and has already placed the corresponding seeds is positioned at the corresponding position of the negative pressure tube group closest to the seeding station 23. At this time, the translation cylinder 29 corresponding to the negative pressure tube group drives the seeding vertical plate 25 to drive each negative pressure tube 24 of the negative pressure tube group to move to the maximum stroke facing the annular conveyor belt 19, so that each negative pressure tube 24 of the negative pressure tube group is located directly above each seeding cup 20 of the corresponding seeding cup group. Then the lifting cylinder 28 drives the seeding vertical plate 25 to drive each negative pressure tube 24 of the negative pressure tube group to move downward and extend into each corresponding seeding cup 20. At this time, the bottom of each negative pressure tube 24 is located at the lower part of the corresponding seed placing cup 20, and then the vacuum tube connected to the negative pressure tube 24 of the negative pressure tube group is connected to the vacuum device to form negative pressure, so that the bottom of each negative pressure tube 24 extending into the seed placing cup 20 can absorb the amount of seeds that can be absorbed, and then the lifting cylinder 28 drives the seed placing vertical plate 25 to drive each negative pressure tube 24 of the group of negative pressure tubes to move upward to the maximum stroke, and then the translation cylinder 29 drives the seed placing vertical plate 25 to drive each negative pressure tube 24 of the group of negative pressure tubes to move back to the annular conveyor 19 to the maximum stroke, so that each negative pressure tube 24 with seeds absorbed is separated from the corresponding seed placing cup 20 and the annular conveyor 19, and the lifting cylinder 28 drives the seed placing vertical plate 25 to drive each negative pressure tube 24 of the group of negative pressure tubes to move downward Move to the maximum stroke, so that the bottom of the negative pressure tube 24 with the seeds adsorbed is closest to the top surface of paper A51. At this time, the vacuum tube connected to the negative pressure tube 24 of the negative pressure tube group is disconnected from the vacuum device and connected to the atmosphere, so that the seeds at the bottom of the negative pressure tube 24 directly fall and stick to the corresponding position of the glue layer of paper A51 under the action of gravity. Then the annular conveyor 19 steps and transports the group of seed placing cups to the corresponding position of the next group of negative pressure tube groups. Then the lifting cylinder 28 and the translation cylinder 29 and the vacuum tube corresponding to the corresponding negative pressure tube group repeat the above actions respectively, so that the negative pressure tube group also adsorbs the seeds in each seed placing cup 20 of the seed placing cup group and sticks them to the corresponding position of the glue layer on the top surface of another paper A51 corresponding to the cover negative pressure tube group.Then the circular conveyor belt 19 again conveys the seed placing cup group to the corresponding positions of other negative pressure pipe groups in sequence, and repeats the above steps so that the negative pressure pipes 24 of the remaining negative pressure pipe groups respectively absorb the seeds in the corresponding seed placing cups 20 of the seed placing cup group and stick them to the corresponding positions of the glue layer on the top surface of the corresponding paper A51. When the negative pressure pipe group farthest from the seed placing station 23 also absorbs the seeds in the corresponding seed placing cups 20 of the seed placing cup group and sticks them to the corresponding positions of the glue layer on the top surface of the corresponding paper A51, the paper A51 continues to be conveyed forward, and the circular conveyor belt 19 The seed placing cup group continues to be conveyed to the end of the horizontal conveyor frame 18 away from the seed placing station 23. When the seed placing cup 20 of the seed placing cup group is stepped and conveyed to the end of the seed placing station 23 of the horizontal conveyor frame 18, the corresponding seed placing cup 20 dumps the residual seeds in the seed placing cup 20 into the seed collecting device 22 during the downward rotation of the annular conveyor belt 19 wound around the transmission roller, and continues to be conveyed to the bottom with the annular conveyor belt 19. After the residual seeds in all the seed placing cups 20 of the seed placing cup group are dumped into the seed collecting device 22, at this time, the seed placing cup 20 of the seed placing cup group The seed placing cups 20 of another seed placing cup group are just transferred to the corresponding position of the negative pressure pipe group closest to the seed placing station 23. At this time, the driving device A21 again pauses the driving of the circular conveyor belt 19 and the paper A51 is again in the paused state of stepping transmission; repeat the above steps to realize the continuous sticking and fixing of the corresponding seeds on the paper A51, and the continuous forward transmission of the paper A51 with the seeds fixed thereon; in addition, the paper B52 unwound by the unwinding device B7 is sequentially stepped through the transition roller C32 and then passed through the pressing roller C42. The hole roller B8 is between the hole roller B8 and the punching plate B35, and the hole slits are uniformly pressed on the surface of the paper B52 by the hole roller B8. The paper B52 with the holes pressed continues to be conveyed forward step by step, and is conveyed through the transition roller D33 and the transition roller E36 in sequence. When conveyed to the position of the pressing roller 9 and the pressing base roller 38, the bottom of the paper B52 contacts the top of the paper A51, and the pressing action of the pressing roller 9 and the pressing base roller 38 makes the bottom of the paper B52 and the top of the paper A51 adhere and fix to form the breeding paper 53. Then the breeding paper 53 is conveyed step by step through the transition roller F39 and then wound by the winding device 10.
