Multiple-head, special-shaped and spiral cell type intensive seeding apparatus for small-sized seeds

Abstract

A precise sower with multiple shaped spiral slots for small seeds has a sleeve barrel with upper seed feeding inlet and lower seed discharging outlet, and a screwed seed discharging axle in said sleeve barrel and with spiral slots on its surface.

Description

technical field The invention relates to the field of agricultural machinery, and is aimed at a seeding device for small-grain precision seeding, in particular to a multi-head special-shaped spiral groove small-grain precision seeding device suitable for small-grain grains such as millet, broomcorn, alfalfa, and vegetables. Background technique With the adjustment of the agricultural industrial structure, the mechanized production technology of small miscellaneous grains has been put on the agenda. In the mechanized production of millet, broomcorn, alfalfa, vegetables and other crops, precise and small amount sowing is a key technology. Precise and small amount sowing can save seeds, make them reasonably distributed in the soil, benefit for strong seedlings, reduce labor for thinning and setting seedlings, reduce fertilizer and light energy loss, increase production and income, and have significant economic benefits. At present, precision seeders for row crops such as corn, ...
