Abstract

一种排种器的牙盘(又称挡圈),能够省去压盖和铆合,在装上排种轮后简便灵活地推进安装,适用较广。

Description

牙盘
所属技术领域:本发明型涉及农用机械,尤其是播种机排种器,排种盒中的牙盘(又称挡圈)。
背景技术:目前,公知的牙盘在实际应用时用压盖铆合,有的不能在排种轮后,按装受到局限,如活窝排种轮端部封闭,就无法在按装排种轮后按装牙盘。
发明型的目的:本发明型的目的是提供一种牙盘,减去压盖和铆合,能简便灵活的按装使用,挡住种子不外漏。
技术方案:本发明型的目的是这样实现的,一种牙盘,圆环形内圆有牙形状结构,其特征是:牙形弹性成凹槽。牙盘中牙的结构有弹性倒钩、按装时顺排种轮往排种盒中推进、倒钩压下,倒钩进入排种盒中弹起,倒钩形成凹槽,随排种轮转动,实现牙盘挡住种子的作用。
有益效果:由于采用上述方案,节省压盖、节省铆合,并且拆装方便灵活,尤其是先装排种轮后上牙盘,适应性广。
图案说明:下面结合附图和实施例对本发明型进一步说明。
图1是本发明型主视图。
图2是本发明型左视图。
图3是牙盘中牙剖面构造图。
图4是牙盘中牙主视图。
图5是牙盘中牙俯视图。
图中1、牙盘2、牙3、倒钩
实现发明型最好方式:在图中,牙盘(1)使用按装时由牙(2)的倒钩(3)在前往排种盒方向推进,倒钩弹起,按装完闭。

Claims (4)

1、一种牙盘,圆环形内圆有牙形状结构,其特征是:牙形弹性成凹槽。
2、根据权利要求1所述牙盘,其特征是:使用时靠倒钩装配。
3、根据权利要求1所述牙盘,其特征是:牙形弹性凹槽对称分布。
4、根据权利要求1所述牙盘,其特征是:牙形弹性凹槽均匀分布。
