Abstract
Description
Technical Field
[0001] The invention relates to the technical field of sowing equipment, in particular to a visual tray seeder. Background Art
[0002] The plug tray seedling raising technology is a modern seedling raising technology that uses light-substrate soilless materials such as peat and vermiculite as seedling raising substrate, mechanized precision sowing, one seed per hole, and one-time seedling growth.
[0003] The current plug tray seeders still have some shortcomings. For example, after some plug tray seeders on the market have been working for a long time, the venting plate is squeezed by the seeding tray, and the seeding needles on the venting plate are in contact with the soil for a long time, which will cause a lot of sludge to be produced by pressing the plug tray. Over time, it may cause damage to the machine and incomplete cultivation of seedlings. During the process of the sowing needle absorbing seeds, the absorption may be incomplete, and the seeds may not be absorbed, resulting in seed leakage.
[0004] Therefore, we made improvements and proposed a visual tray seeder. Summary of the invention
