Automatic sphericity falling device and automatic seeding system for plant growth grooved tray

Abstract

The invention relates to an automatic ball-dropping device for automatically dropping gel-coated seeds and an automatic seeding system for a seedling-raising trough. The gel-coated seeds can be dropped correctly in a very short time without scratching the gel-coated seeds. The device is composed of a conveying roller unit (70) that clamps the disc-shaped conveying roller (42) by plates A and B to make it rotatable, and is installed on the side of the conveying roller unit, and is equipped with a driving device for driving the conveying roller. Etc. C board composition. And, the gel-coated seeds (50) from the hopper are supplied into the gel-coated seeds holding recesses (42a) arranged on the outer periphery of the conveying rollers, and are transported to the lower part of the conveying roller unit as the conveying rollers rotate. The lower output falls down. The friction rubber (27) arranged opposite to the outer peripheral surface of the conveying roller swings in a state of keeping in contact with the outer periphery of the conveying roller, so as to prevent bridging at the bottom.

Description

technical field [0001] The present invention relates to a method for securely accommodating one seed in a concave portion such as gel-coated seeds other than gel-coated seeds or gel-coated seeds or shaped seeds so that they can fall down accurately and quickly automatically Automatic ball drop device and automatic seeding system for seedling trays. Background technique [0002] In recent years, in agriculture, in order not to be affected by the climate, more and more reliable seedlings have been adopted. The method of growing seedlings in a greenhouse or the like to the size of a seedling tray and then transplanting them into the field instead of directly planting them in the field The method of sowing seedlings. As an apparatus for seeding, for example, there is a vacuum seeder shown in FIG. 16 . [0003] The vacuum seeder shown in FIG. 16 has a structure in which a vacuum seeder main body 92 is fixed to a transfer table 91 . [0004] The vacuum seeder main body 92 has a...

Problems solved by technology

As a result, there is a problem that it takes a lot of time and costs to sow gel-coated seeds

[0008] In addition, since the position where the seeds are released is high, the seeds sometimes fall into the grooves of the seedling trays with the momentum of falling, and there is a problem that it is difficult to correctly sow seeds into the soil pits of the seedling trays.
