AI Technical Summary

Technical Problem

Existing seeders cannot simultaneously perform seed sowing and fertilization, resulting in a fragmented sowing process, increased operational steps and time costs, and difficulty in meeting the high-efficiency and integrated production needs of modern agriculture.

Method used

A precision seeding planter was designed. A servo motor drives a reducer to rotate two rotating shafts in opposite directions at the same speed. Combined with separating wheels in opposite directions, it realizes the alternating delivery and mixed sowing of seeds and fertilizers. Combined with a mixing guide tube and a plow blade, it directly completes the uniform mixing and sowing of seeds and fertilizers in the soil.

Benefits of technology

This method enables simultaneous sowing of seeds and fertilizers, reduces repetitive field operations, ensures uniform water and fertilizer ratios, improves sowing efficiency and operational uniformity, and avoids resource waste.

Abstract

This utility model discloses a precision seeding device, relating to the field of agricultural planting technology. It includes a seeding device body, one end of which is equipped with a plow blade, and the other end with two rotating shafts that rotate in opposite directions. Separating wheels are fixedly connected to the outer walls of the rotating shafts, and these wheels are evenly distributed on the outer walls. The outer sides of each separating wheel are provided with toothed grooves, and the grooves on the two rotating shafts are oriented in opposite directions. This utility model uses a servo motor to drive a reducer, causing the two rotating shafts to rotate in opposite directions at the same speed. Combined with the separating wheels with opposite toothed groove directions, seeds and fertilizer fed into the funnel are alternately transported at a ratio of one unit of seed to one unit of fertilizer. After mixing through a mixing conduit, the mixture is sown into the soil tilled by the plow blade, eliminating the need for subsequent separate fertilization, significantly reducing field operations, ensuring uniform water and fertilizer ratios, and avoiding resource waste.
