Embodiment Construction
[0014] The present invention will be described in detail below with examples in conjunction with the accompanying drawings.
[0015] This tiny seed sower includes a portable compressed air source device and a portable tiny seed storage, characterized in that one end of the tiny seed storage has a seed outlet with a diameter 3-5 times the seed diameter, and the other end has a compressed air inlet , and communicate with the compressed air source device. And it can be easily installed and disassembled. A decompression hole is arranged at the side of the compressed air inlet end of the tiny seed storage to buffer the air pressure in the tiny seed storage.
[0016] combine figure 1 , a simple method is: the tiny seed storage device is a plastic bottle 1 with a cap and a volume of 500ml, and the cap 7 is screw-connected with the bottle mouth; the compressed air source device is a portable pump 2; 1. The bottle cap is removed, and the bottle cap 7 is connected and fixed with the ...

The invention relates to a small-seed seeder. The small-seed seeder comprises a portable pressing gas source device and a portable small-seed storage, wherein a seed outlet, of which the diameter is 3 to 5 times that of each seed, is formed in one end of the small-seed storage, and the other end of the small-seed storage communicates with the pressing gas source device; the small-seed seeder can be mounted and dismounted conveniently. A pressure relief vent is formed in a side face of a pressing gas inlet end of the small-seed storage. A simple practice is as follows: seeds, of which the volume does not exceed two-thirds the volume of the small-seed storage, are loaded to the small-seed storage through an entrance end of the small-seed storage, and then, the entrance end of the small-seed storage is in screwed connection with a bottle cap fixed on an air outlet tap of an inflator so as to form the small-seed seeder. The small seeds will be uniformly ejected from the seed outlet along with airflow through pushing and pulling a hand lever of the inflator. The small-seed seeder can also be applied to seedling beds. The small-seed seeder is applicable to the large-scale seeding of small seeds; compared with the existing oral-blowing seeding methods, the small-seed seeder has the advantages that the seeding is more uniform, the seeding efficiency is 50 or more times higher, and the labor intensity of seeding is remarkably lowered.
Description
technical field [0001] The invention relates to an agricultural production tool, that is, a tiny seed sower. Background technique [0002] Seedling-transplanting is the basic method of plant production. Seed sowing of general field crops and horticultural crops has been mechanized. Some small seeds, such as tobacco seeds, are sown by seed coating, changing their shape (pelletization), and increasing their volume, which can still adapt to mechanized sowing. However, in plant production, there are still some plant seeds that are as small as dust, several times smaller or slightly lighter than tobacco seeds, and cannot be coated, and it is not suitable to use the method of mixing with river sand and other materials before sowing, because this Kinds of seeds germinating should not have any covering. How to ensure the uniformity of sowing and improve the sowing efficiency is a difficult problem in the seedling breeding of such plants. Such as the spores of orchid seeds such as...
