Description

Technical Field

[0001] The 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 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 experiments is very limited, and it is impossible to use sufficient or excessive test seeds on the seedling-raising paper where glue is applied so that each glue spot is fixed with the experimental seeds through vibration.
