Abstract

一种弧形小铲,本实用新型适宜行距窄株距小的禾谷类农作物在小苗期间的间苗除草使用,比传统的小锄速度快,还能剜坑把多余的苗移栽到缺苗的位置上,也能移栽蔬菜苗和花卉苗,能铲除其它作物小苗阶段的杂草。其特征是包括弧形铲板、三角尖铲头、手柄和半圆挡头;弧形铲板长为15厘米,宽8厘米,厚1毫米;三角尖铲头的内角为130度;弧形铲板的弧底最深处为5毫米;手柄的长为15厘米,外直径25毫米,厚1毫米;半圆挡头用与手柄外直径相等的半圆形螺丝帽的螺丝;弧形铲板的左右两边和三角铲头都磨成刀刃;手柄前端为向下弯的圆弧形,斜切口连接在弧形铲板后端中间。

Description

一种弧形小铲
技术领域
本实用新型涉及一种农田间苗除草用的小农具。
技术背景
禾谷类作物,因行距和株距都小,从种籽到间苗其间如果雨水多,杂草就长的特别快,给人们间苗造成很大困难。一般间苗锄草人们都用小锄,小锄锄一寸以下的草挺快,但是草长到一寸以上草叶乱草根又深又多,用小锄锄草就慢了许多。因为小锄锄草是顺着手柄的方向向后拉,小锄每向后拉一下都得把杂草铡断锄刃才能进入土里锄断草根,锄刃没有刀刃锋利,所以锄刃就很难铡断地面上的杂草和地面下的草根,锄草的速度就会很慢,慢了费的时间就长,草就有时间继续长,行成了恶性后果;还有,谷物从播种到出苗期间,如果遇上干旱有的垄不出苗造成缺苗,或者大雨把刚出土的苗埋没也会造成缺苗,要想补苗还得另外换别的工具,用小锄间苗不能把多余的苗补栽到缺苗的位置。
发明内容
本实用新型针对上述已有工具的不足,提供一种弧形小铲。
一种弧形小铲,其特征是包括弧形铲板、三角尖铲头、手柄和半圆挡头;弧形铲板长为15厘米,宽8厘米,厚1毫米;三角尖铲头的内角为130度;弧形铲板的弧底最深处为5毫米;手柄的长为15厘米,外直径25毫米,厚1毫米;半圆挡头用与手柄外直径相等的半圆形螺丝帽的螺丝;弧形铲板的左右两边和三角尖铲头都磨成刀刃;手柄前端为向下弯的圆弧形,斜切口连接在弧形铲板后端中间。
本实用新型的弧形铲板用1毫米厚的锯条钢钢板磨出来的刃锋利,耐用,前后向上弯弓背朝下有利于调节铲板的角度;三角尖铲头能用不同姿势方便地铲掉谷苗间用小锄进不去锄不掉的草,三角尖铲头的两条边磨成刀刃向前推对于草根来说是斜割,很省力;弧形铲板的两边刃是为铲除两侧的草提供了方便,可以左右铲草;手柄前端向下弯,斜切口连接弧形铲板,手握住手柄向前推铲时二母指在下面正好顶住向下弯的手柄前下端,不怕手往前滑;因为手柄是空管,用半圆形螺丝帽挡住手柄后面的孔,既得力又不怕割手。这种铲看起来小,又简单,但每一个特征部分都起着非常重要的作用,正是因为如此,用它干起活来特别快。首先这种铲对付小草可以快速地左右刮,左右斜着刮;觉得不好刮的草就左右铲,向前铲;比如要是向前推铲,每向前铲3次才用3/4秒,退出铲来还能休息1/4秒,这还是60岁以上的人的速度,年轻人的速度更快。还有,如果在间苗时遇上缺苗的空垄,还可以用铲挖小坑,把多余的苗剜起来当时就能栽上,把苗用最短的时间移栽上浇上水成活率最高。另外还能移栽蔬菜苗和花卉苗,也能铲除其它作物小苗阶段的杂草。
附图说明
图1为本实用新型结构示意图。
图中:1、弧形铲板,2、三角尖铲头,3、手柄,4、半圆挡头。
具体实施方式
铲板选1毫米厚的锯条钢钢板,在钢板上画出所要的尺寸,割开后放在火上加温,拿出来放入弧形模具里冷却;把30厘米长两头管口内车好内丝扣的管子以中间为界对弯回来,两头弯回来的距离是10厘米为宜,从中间截断,一分就是两个手柄;把手柄有斜切口的一头焊接在弧形铲板后端的中间,把半圆螺丝帽的螺丝扭在手柄后面的孔内;用砂轮将弧形铲板两边和三角尖铲头磨出刀刃。
为了减轻弧形小铲的重量,半圆形螺丝帽的螺丝可选用塑料螺丝。
