Abstract

脚踏链条传动轻便两用脱粒机,由谷斗、谷围、辊简和链条传动机构等组成,机斗合一并装有出谷门,既可用于各种条件下的谷物收成脱粒,又可切割稻草回田,且轻便易搬动,打谷效率是老式人力脱粒的三倍,每亩稻谷损失又可降低5~6斤,是我国广大农村特别是山区收成脱粒的一种理想机械。

Description

本实用新型属农业机械技术领域。
老式的收成脱粒采用人力在木桶内摔打脱粒,效率低,劳动量大且谷粒损失多;近代虽有机械化收割机,因成本高,难于普及,且不宜在山田作业。中国专利号为85200958的柔性传动脚踏脱粒机采用柔性传动带传动虽有许多优点,但在重负荷或在水田作业下容易打滑,且没有解决谷粒损失和稻草回田问题。
本实用新型的目的是设计出一种轻便、适用面广,又能解决稻草回田问题的两用脱粒机械。
本实用新型的脱粒机结构为机斗合一,采用链条传动,且装有稻草回田装置,从而克服了柔性传动脚踏脱粒机的上述缺点。
本实用新型经农民试用,打谷速度为老式人工脱粒的三倍,每亩稻谷损失降低5~6斤,普遍认为是当前我国农村的一种优良脱粒机械,适合我国广大农村的国情。
下面结合附图给出本实用新型的一种实施例:
如附图所示,图中1为本脱粒机机架,2为扶手板,3为割草刀,4为左右罩板,5为谷围,6为刀夹,7为抬环,8为出谷门,9为主轴,10为滚筒,11为小链轮,12为链条,13为大链轮,14为脚踏杠杆,15为拉杆,16为脚踏板,17为连杆,18为轴承,19为链盖,20为拉手。本实用新型靠脚踩踏板16来驱动一种四连杆机构,四连杆机构由脚踏杠杆14、拉杆15和连杆17组成。通过四连杆机构带动大链轮13转动,通过链条12传至小链轮11提高主轴9的转速,从而使滚筒10运转,滚筒10上安有钉齿。将割下的稻子(或小麦等)置于滚筒10上进行脱粒,脱下的谷粒堆集于由左右罩板4与谷围5及出谷门8组成的谷斗中,待斗中存谷快满时,停止脱粒,打开出谷门,取出谷子。脱粒后的稻草可顺手在割草刀3上回拉割断,散于田中,达到稻草回田的目的。割刀为活动式,停用后可将割刀合置刀夹6内,即完成实施全过程。
操作时先以手触动滚筒10使其成顺时针方向转动,然后脚踩踏板16使滚筒加速,即可进行脱粒,脱下的谷粒堆集于谷斗中,脱粒后的稻草可顺手在割草刀上回拉割断散于田中,斗中存谷快满时停止脱粒,打开出谷门取出谷子。
