Abstract

一种护罩圆状型有对称的弹性钩,安装简便,成本低廉,不卡种,不漏播,使用寿命长。

Description

护罩
所属技术领域:
本发明型涉及农业机械,尤其是播种机精密排种器上的护罩。
背景技术:
目前排种器上的护罩是断开口,在实用中降低护罩整体强度,排种轮与护罩转速不一致,排种轮转速快;护罩转速慢,排种轮推动种子进入开口(包括锐角开口)时有发生,加大磨损。开口处漏种错播,无规律的撒种产生至命缺陷。
发明内容:
为了克服现有护罩的缺陷,本发明提供一种封闭护罩无断开口在工作转动中增加了护罩的强度,使之无口可入不卡、漏种子的护罩。
[0004]本发明目的是这样实现的,排种盒、排种轮、刮种器、外圆与弹性钩形成凹槽的护罩,护罩常用弹性塑料制做,本发明的护罩实际上是一种用于播种机排种器上的护罩,减轻排种轮与排种盒之间摩擦延长使用寿命。一种用于播种机排种器上的护罩,该护罩呈环状,用于排种盒侧壁内圆上,护罩内圆装有排种轮,圆状护罩有对称的弹性钩,或三角形分布的弹性钩,安装时利用弹性将弹性钩推入排种盒侧壁内圆。
有益效果是,由于采用上述方案、增加了护罩的强度,护罩转动通畅,使用寿命长,所排放的颗粒不会产生卡种、漏播,排种器达到至善完美,成本低廉,操作使用简便。
附图说明:
下面结合附图和实施例进一步说明。
图1是排种盒与窝眼式排种轮及护罩结合图。
图2是护罩结构图。
图中1护罩、2护罩弹性钩、3、窝眼式排种轮左视结构图,4、排种盒。
具体实施方式
在图1中排种盒(4)安装在播种机种子箱底部,排种轮(3)与阻塞套并排在排钟盒(4)的中部,中心是播种轴,排种轮(3)斜上方是刮种器、排种轮(3)与排种盒(4)转动摩擦的圆处是护罩(1)、外圆与弹性钩(2)形成凹槽套在排种盒侧壁内圆上,是弹性钩(2)利用自身的弹性由侧面装、卸简便。

Claims (3)

1.一种用于播种机排种器上的护罩,该护罩呈环状,用于排种盒侧壁内圆上,护罩内圆装有排种轮,其特征是:圆状护罩有的弹性钩。
2.根据权利要求1所述的护罩,其特征是:圆状护罩的弹性钩对称分布。
