AI Technical Summary

Technical Problem

Existing negative pressure seeders require multiple seed adsorption and transfer processes in Fritillaria cirrhosa plug tray seedling cultivation, resulting in low efficiency and failing to meet the high-efficiency seeding requirements of 128-cell or 50-72-cell plug trays.

Method used

A seedling sowing device for Fritillaria cirrhosa in plug trays was designed, including a storage hopper, a feeding roller, a stop block, and an adjustment component. Through the cooperation of the storage hopper and the stop block, multiple seeds can be contained and transferred at one time. The depth of the container groove can be adjusted by the radial movement of the stop block to meet the needs of different plug tray diameters.

Benefits of technology

It improves the sowing efficiency of Fritillaria cirrhosa seedling tray cultivation, enabling the insertion of multiple seeds at once, adapting to the needs of seed trays with different hole sizes, and improving work efficiency.

Abstract

The utility model relates to the field of bulbus fritillariae cirrhosae planting, in particular to a bulbus fritillariae cirrhosae plug seedling seeding device. The bulbus fritillariae cirrhosae plug seedling seeding device comprises a storage hopper, the upper portion of the storage hopper is in a boss shape, the lower portion of the storage hopper is in a semi-cylindrical shape, and a discharging port is formed in the lowest position of the lower portion; the feeding roller is located on the lower portion of the storage hopper, a cavity is formed in the feeding roller, a plurality of penetrating openings are formed in the circumferential outer wall of the feeding roller, and storage cylinders corresponding to the penetrating openings are integrally connected to the circumferential inner wall of the feeding roller; the stop block is located in the storage cylinder; and the adjusting assembly is rotationally installed in the feeding roller and further connected with the check block. In the bulbus fritillariae cirrhosae plug seedling seeding device provided by the utility model, the storage barrel is arranged on the feeding roller and is matched with the stop block to form the accommodating groove, so that a plurality of seeds can be accommodated and transferred at one time, the depth of the accommodating groove can be adjusted through the radial movement of the stop block, the accommodating capacity can be adjusted according to the size of a plug hole, and the seeding efficiency can be further improved.
