Abstract

农用尖齿锄。目前的锄头的锄刃外边缘为一条弧线,工作阻力大、操作费力。而这种尖齿锄的锄刃则是由多个尖齿构成,入土性能好,省力,便于操作。

Description

尖齿锄
技术领域:本实用新型是一种农具,即一种农用手工尖齿锄。
背景技术:农民铲地用的锄头,多由锄板、锄钩和锄把构成,其锄板是两条曲向相反的弧线对扣在一起构成的板面,一条弧线称为锄背,另一条称锄刃或锄锋。锄背连接锄钩及锄把,锄锋及两端的锄角为入土铲草间苗的主要工作部位。锄头历史悠久,至今仍是中国农民田间管理的重要工具。然而,锄头也存在着锄锋入土阻力大,使用费力,不便掌握等缺点。
发明内容:本实用新型的目的是研制一种入土性能好,阻力小,省力,便于掌握的锄头。这一目的是由以下技术方案实现的:这种锄头也有一个锄板,锄板也有锄背和锄锋,所不同的是:所说的锄锋是由多个尖齿构成的。
所说的锄背的外缘线是由三条弧线对接而成,两侧的弧线向内弯曲,中段的弧线向外弯曲,中段弧线与两侧弧线连接处,形成两个向外的侧尖角。
采用上述方案制成的锄头,使用时,齿尖入土,压强较大,加上齿尖两侧为斜线,相对被切割物的正面压力较小,从而达到了阻力小,省力,便于掌握的目的。
附图说明:图1是一种实施方式的主视图,图2是其左视图。图3是使用状态示意图。
图中可见:锄背1、锄锋2、锄钩3、尖齿4、侧尖角5。
实施方式:由图可见,这种锄头也有锄背1和锄锋2,而锄锋1上带有多个尖齿4,锄背中段向内弯曲,两侧各有一个向外的侧尖角5。侧尖角的作用是在向前伸推的过程中去除个别的杂草或余苗。

Claims (2)

1、一种锄头,也有一个锄板,锄板也有锄背(1)和锄锋(2),其特征在于:所说的锄锋(2)是由多个尖齿(4)构成的。
2、根据权利1所述的尖齿锄,其特征在于:锄背(1)的外缘线是由三条弧线对接而成,两侧的弧线向内弯曲,中段的弧线向外弯曲,中段弧线与两侧弧线连接处,形成两个向外的侧尖角(5)。
