Seeding device of tobacco floating seedling raising plate

Abstract

The invention discloses a seeding device of a tobacco floating seedling raising plate. The seeding device comprises a conveying mechanism of the seedling raising plate, and a first substrate discharging hopper, a first substrate scraping mechanism, a first indenting mechanism, a second substrate discharging hopper, a second substrate scraping mechanism and an indenting and seeding integrated mechanism which are sequentially distributed along the conveying mechanism; the first indenting mechanism adopts a disc type structure; the indenting and seeding integrated mechanism is used for screeningseeds and then conveying the seeds into a material dividing plate, and the seeds are discharged one by one through three layers of staggered plates of the material dividing plate; then secondary indenting and seeding are completed at the same time through a combined conical indenting seeding hopper and a round-head indenting bar. Two times of substrate filling and indenting fully guarantee formingof seed pits; the indenting and seeding integrated mechanism guarantees that the seeding positions are proper, the device is reliable and lasting in work, it is guaranteed that the seeding success rate can reach 195 / 200, thinning is not needed, the seeding quality is improved, and the seedling quality of tobacco seedlings is ensured.

Description

technical field [0001] The invention relates to a sowing device of a tobacco floating seedling raising tray. Background technique [0002] During the cultivation of tobacco, flowers, vegetables and other crops, the seeder is used to sow the seedling holes of the floating seedling tray. In the prior art, such as the "floating seedling raising tray seeder" disclosed in the utility model patent document with the authorized announcement number CN201256532Y, during the seedling raising tray transmission process: the method of flooding the hopper and scraping the scraper plate is used in the seedling raising grid hole. Fill the matrix; press the matrix in the seedling hole of the seedling tray through the rotation of the pressing roller; the seeds stored in the holes on it fall into the hole through the rotation of the seeding roller, thereby completing the pressing and sowing Work. This is also the mainstream device widely used in the tobacco system now. [0003] In addition, ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the prior art are: firstly, the highest seeding success rate can only reach 95%, and there are phenomena of missed sowing and multi-sowing, and manual thinning procedures are required to transplant the redundant seedlings in the multi-sowing grid holes into the missing-sowing grid holes However, the thinning process is time-consuming and labor-intensive. According to financial statistics, the labor required for thinning accounts for 50% or more of the entire labor for seedling cultivation.

Second, the quality of sowing needs to be improved: because the matrix may form agglomerates, and after falling into the seedling grid holes of the seedling tray, the matrix in the grid will be filled with voids, and the seed holes pressed by the pressure hole roller will not be formed; the seed holes are in the seedling grid holes If it is not in the middle, the seeds are easy to fall off during the transportation of the seedling tray, the growth space of the tobacco seedlings is limited, the growth is poor, and even the seedlings cannot be formed
