内充式精准定量排种器
本技术涉及作物种子排种器,尤其涉及一种内充式精准定量排种器。
技术介绍
随着农业机械技术的不断发展,作物种子的播种方式已经由传统的人工播种方式向机械播种、精密播种等方式发展。现有的排种器主要包括外壳、设于外壳内的储种盘、设于储种盘前端外缘上部的弧形护种板、设于外壳与储种盘之间的排种盘、设于排种盘轴心且穿过外壳与储种盘的滚轴、周向设于排种盘外缘的种孔、设于外壳侧壁靠近弧形护种板末端的排种口。排种操作时,与排种车行走轮通过传动机构连接的滚轴带动排种盘逆时针转动,储种盘内的作物种子依次充入位于排种盘底部的种孔内,在弧形护种板和外壳侧壁的保护作用下,跟随逆时针转动的排种盘转动到排种口处,在重力作用下,种孔内的作物种子经排种口掉落到耕地,实现定距排种。由于作物种子大小不一致,同一种穴内有时装有二个以上较小的作物种子,导致耕地同一位置作物种子过多造成浪费现象发生;且较大作物种子转动排种口处时,因作物种子夹在排种孔内不易掉落,造成耕地种沟缺种,排种不精准,影响作物产量。
技术实现思路
本技术是为了解决上述技术问题,提供一种内充式精准定量排种器,其可将同一种穴内多余的作物种子拨回储种盘,避免耕地同一位置作物种子过多造成的浪费现象发生;并可将转动到排种口处的作物种子顺利排出,防止耕地缺种,实现精准排种,保证作物产量。本技术的技术解决方案是:一种内充式精准定量排种器,包括外壳,设于外壳内的储种盘,设于储种盘上的弧形护种板,设于外壳侧壁靠近弧形护种板末端的排种口,设于外壳与储种盘之间的排种盘,设于排种盘轴心且穿过外壳与储种盘中心孔的传动轴,周向设于排种盘外周板 ...
