Abstract

管式排种器由容器2、弯管1和转轴6构成,容器为筒形,两端封闭,两端中心固连转轴6,一端有装种口5,周壁上均匀分布孔眼,每一孔眼匹配固连一弯管1,所有弯管向同一方向緾绕在容器的周壁上,在弯管与容器孔眼接口处有取种勺4,取种勺4的出口朝筒壁外侧的弯管方向;这种排种器结构简单,容易制造,播种不伤种,不粘籽,播种效率高,精度高。特别适合油菜籽等小颗粒种子播种。

Description

管式排种器
一.技术领域
管式排种器涉及播种机领域。
二.背景技术
市场上没有适应油菜等小颗粒种子的结构简单的小型排种器。
三.发明内容
提供一种能对油菜等小颗粒种子播种的结构简单的小型排种器。其具体方法如下。
在封闭的筒形容器2的周壁上开若干个孔眼(参见附图1、附图2),每个孔眼接1个弯管1,所有弯管按同一方向緾绕固定在筒形容器的周壁上,弯管的长度在筒形容器周长的三分之一致二分之一之间,始端处固定一取种勺4,取种勺的出口朝筒壁外侧的弯管方向,在筒形容器的两端中心固连一转轴6,在一端开一装种口5。
工作过程(参见附图3),将适量油菜籽7从装种口5处装入容器2,使容器绕转轴6沿逆时针方向旋转,则弯管的始端在容器低处时,油菜籽进入弯管,当弯管始端向高处转动时,管内油菜籽一部分回流到取种勺中,多余的油菜籽回流到容器中,当取种勺转动到开口向下倾斜时,油菜籽流出取种勺,进入弯管,顺弯管从上向下流动,经管道末端的出口3流出。
在容器中装入种子的量及容器旋转速度,以种子不能从弯管中直接流出为准。
四.附图说明。
图1是管式排种器的立体结构示意图。
图2是图1中A—A剖切图。
图3是排种器原理说明图。
图中1为弯管、2为容器、3为出口、4为取种勺、5为装种口、6为转轴、7为油菜籽。
五.具体实施方式。
下面结合附图对管式排种器的结构、原理作进一步说明。
管式排种器由容器2、弯管1和转轴6构成,容器为筒形,两端封闭,两端中心固连转轴6,一端有装种口5,周壁上均匀分布孔眼,每一孔眼匹配固连一弯管1,所有弯管向同一方向緾绕在容器的周壁上,在弯管与容器孔眼接口处有取种勺4,取种勺4的出口朝筒壁外侧的弯管方向;取种勺为碗状,口面直径为2.5毫米,深度为2毫米;容器为圆筒形,弯管长度是容器侧壁周长的1/3—1/2,弯管的孔径为8—15毫米。
这种排种器结构简单,容易制造,播种不伤种,不粘籽,播种效率高,精度高。
