Description

一种气吸式排种器带式导种装置
技术领域
本发明涉及农业技术领域,尤其是涉及一种气吸式排种器带式导种装置。
背景技术
免耕精密播种机多在未经耕整过的茬地作业,为保证在恶劣条件下具有较好的作业性能,设计的开沟装置一般采用双圆盘式开沟器。其主要优点是通过性好,使用可靠。主要缺陷是:种子在实际下落过程中,受重力作用由吸孔落下,沿开沟器输种通道运动时受到管壁的弹碰,使每粒种子由型孔落入种沟的时间发生变化,另外由于种子自振幅度的不同,落入种沟安定在种床上的时间也极不相同。导致播后种子粒距变异系数大,合格指数低。
发明内容
为克服上述问题,本发明采用如下技术方案:
一种气吸式排种器带式导种装置,包括取种盘和中间转动轮,所述取种盘的下部一侧设有导槽,另一侧设有中间传动轮,中间传动轮与从动轮齿合,从动轮的内部设有主动带轮,从动轮与从动带轮通过种子输送带连接,种子输送带的两侧设有种道护板,种道护板上设有拨片,拨片上置有种子,所述种子输送带的下部设有种沟。
所述拨片结构为波浪形,防止种子晃动、滑落。
排取种盘转速为30r/min。
本发明的优点是:带式导装装置可以将种子输送到最佳的投种高度,种子到达投种位置是的粒距得到精确矫正,种子拨入种沟后株距合格率大福提高,且该结构合理,可在恶劣环境下作业。
附图说明
图1为本发明的结构示意图。
具体实施方式
如图1所示,一种气吸式排种器带式导种装置,包括取种盘1和中间转动轮2,所述取种盘1的下部一侧设有导槽3,另一侧设有中间传动轮2,中间传动轮2与从动轮4齿合,从动轮4的内部设有主动带轮5,从动轮4与从动带轮9通过种子输送带7连接,种子输送带7的两侧设有种道护板6,种道护板6上设有拨片8,拨片上置于8上置有种子10,所述种子输送带7的下部设有种沟11。
所述拨片8结构为波浪形,放置种子时不宜晃动。
所述排取种盘1转速为30r/min。
工作过程如下:
在种子10随取种盘1转动到达排种器上的投种区时,种子10以取种盘1型孔的线速度为初速度,在重力的作用下做自由落体运动。经过导槽3导入安装在双圆盘开沟器中间的带式导种装置,种子10在重力的作用下掉落到种子输送带7。带式导种装置由取种盘1驱动,动力由取种盘1通过中间传动轮2传递至从动轮4,从动轮4与主动带轮5同步转动,使种子输送带7逆时针转动,使种子10向下运动。种子输送带7两侧设有种道护板6,以保护种子10在离心力和震动的作用下不会脱离种子输送带7与种道护板6形成的种子输送腔。当种子10运动到导种装置投种点时,在重力的作用下落入种沟11,完成导种过程。
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本领域的技术人员在本发明所揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本发明的保护范围之内。
