AI Technical Summary

Technical Problem

Existing seed extractors cause mechanical damage to fragile seeds, such as beet pellet seeds, during precision seeding, and it is difficult to effectively reduce the breakage rate.

Method used

Design a seed extractor with a circular seed extraction hole and an extension in front of the seed extraction hole. The seed extraction hole is divided into three curved surfaces. Curved surfaces one and two are nearly perpendicular to the circular surface, while curved surface three forms a large angle with the circular surface on the back, which reduces friction between the seed and the isolation plate and reduces mechanical damage.

Benefits of technology

It achieves the goal of reducing mechanical damage to seeds, improving seed collection efficiency, ensuring that fragile seeds are not damaged excessively, and smoothly completing the seed collection, transport, and sorting process.

Abstract

本发明涉及农业机械领域,特别是涉及一种颗粒种子取种器及其播种装置。现有取种器存在以下问题:(1)传统取种孔结构对种子姿态适应性差,取种成功率低;(2)易碎种子(如甜菜种子)在取种过程中破损率高。一种颗粒种子取种器,包括圆环形取种器本体,取种器外边缘设有若干取种孔,取种孔前方设有延伸部;取种孔在垂直于正面圆环面的方向上分为至少三个曲面:曲面一位于靠近正面圆环面部分,厚度略小于种子半径;曲面二位于曲面一向内延伸处,垂直或接近垂直于背面圆环面;曲面三位于曲面二前方,与背面圆环面形成大倾斜角;曲面一和曲面二与取种器外边缘形成凸起的取种钩。取种孔厚度和曲面一底部直径均为种子最大直径的1.05~1.5倍。通过多曲面取种孔结构,配合取种钩设计,可有效包裹种子,降低取种时种子掉落风险;采用渐变曲面引导种子进入取种孔,提高取种成功率;垂直于取种器的曲面可以降低对种子到挤压力,可有效保护易碎种子,降低破损率;延伸部采用平滑过渡设计,增加取种到成功率。
