Description

Technical Field

[0001] The present invention relates to the technical field of seedling raising equipment, and in particular to a precision seedling raising and seeding machine. Background Art

[0002] The applicant has previously developed a patented device for a printing seed drill, which is to pre-dot glue on the corresponding positions of the seedling paper, and then vibrate a sufficient amount of seeds on the vertical surface, so that the positions of the seedling paper with glue dots can fix the seeds. The seedling paper with fixed seeds is then rolled up, and when it is necessary to sow seedlings, the seedling paper is unfolded into the field or cut and placed in the seedling tray. However, this printing seed drill has the problems of relatively low glue dot efficiency and seed sticking efficiency, and the seeds fixed on the seedling paper are fixed to the surface of the seedling paper by glue. The seeds are exposed to the outside, and in the later turnover planting process, the seeds may fall off the seedling paper and be lost. When the seedlings are spread in the field, the probability of the seeds being eaten by rodents or birds in the field will increase, resulting in a lower seedling success rate, and then a reduction in 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 completed with seed sticking, another layer of seedling paper is fixed on the end surface of the seed sticking paper to form a double-layer seedling paper and then rolled up, thereby solving the problem of seeds falling during the turnover process and preventing seeds from being exposed to the outside and eaten by birds and rodents during seedling cultivation.

[0004] However, in actual production, it is found that the traditional printing seeders and double-layer seedling paper sticking machines 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 comes into contact with the glue dots, they will be stuck and fixed by the glue dots. This results in different glue dots fixing different numbers of seeds. Some glue dots may only fix 2 to 3 seeds after vibration, while some may fix 4 to 5 seeds. This results in different amounts of seedlings at positions corresponding to different glue dots when the seedlings emerge in the later stage. 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 glue dot position contacts is relatively small. During the turnover of the seedling paper, it is still However, some of the seeds at the glue point will no longer be fixed to the rice paper and will separate, which means that the single-layer rice paper will still cause a reduction in actual production output, and its use in scientific research will still make the test results inaccurate; although the double-layer rice paper can still keep the seeds that are no longer fixed to the rice paper between the two layers of rice paper, and can still be used to grow rice seedlings in the later stage, their position is no longer fixed to the rice paper, so the rice seedlings produced by the rice paper will appear in a position outside the regular seedling emergence position, and the two layers of rice paper are only fixed by various glue points, that is, the rest of the positions between the two layers of rice 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 two layers of rice paper. If the double-layer rice paper is used for scientific research experiments, it will make it impossible to determine what kind of experimental species the rice seedlings that are not in the regular seedling emergence position are, resulting in inaccurate test results.

[0005] In addition, for scientific research experiments, the amount of seeds used for the experiments is very limited, and it is impossible to use sufficient or excessive experimental seeds on the seedling-raising paper on which the glue is applied so that each glue point is fixed with the experimental seeds through vibration. Summary of the Invention
