Description

旋转式杂草除根器
技术领域
本发明专利涉及一种除草设备， 具体的说是一种旋转式剪除杂草的设备， 可有效去除草根。
背景技术
目前的除草设备， 已经公开的的除草设备， 如中国实用新型专利
ZL200520019132.5公开的滚切式除草轮， 采用滚切的结构， 将土壤翻动， 进而 将土壤中的杂草除掉， 其设计的主要思路是采用滚切轮上沿切向安装的扁铲刀 进行挑土， 把草根翻到地面上来。 这样的除草设备一般只适用于大面积的杂草， 不能适用于单个或者几颗的杂草。
中国专利文献 CN101095388公开的滚切圆盘式行间除草机，主要采用机架、 凹形圆盘、 固定架和悬挂臂组成， 在机架上前后交错安装两排除草装置， 每个 除草装置都是由两个 EJ形圆盘组成， 每个圆盘均与前进方向成 25。 -30° 夹角， 两圆盘前后错开呈人字分布。 该文献公开的设备在工作中， 不需要动力驱动， 只需要圆盘与土壤间的摩擦力带动旋转， 从而达到除草的目的。 这样的设备只 是用于田间除杂草， 不能适用于去除绿化草地里的杂草。
绿化草地里的杂草， 在现实中大都是用人手工进行操作拔出的， 一方面由 于手工操作效率低， 另一方面， 手工除草的质量也不能完全保证， 尤其是不能 保证有效的除根。
而针对有些绿地会有土质生硬的情况， 普通的手工除杂草就变得非常困难 了， 即使使用一些筒单的机械也会很不方便。
发明内容
本发明专利设计的是一种去除绿化草地里杂草的设备， 填补该项领域的空 白。
本发明的目的是通过以下技术方案来实现的。
旋转式杂草除根器， 包括筒形的壳体， 在壳体内设置有电机和与电机连接 的变速器， 变速器的头部驱动一个刀杆， 刀杆的头部安装组合刀具， 用直流电 池或交流电进行供电驱动电机带动变速器， 进而通过刀杆带动组合刀具旋转； 在壳体的尾部安装一连接杆， 在连接杆的末端安装控制手柄， 直流电池的电源 线从连接杆内穿过， 并在手柄上设置有调速开关和充电插座。
在筒形壳体的前端设置有三角支架， 三角支架与壳体铰接， 并在铰轴上安 装有复位弹簧， 三角支架的末端安装有滚轮。
所述手柄上设置的充电插座可通过充电器进行充电， 手柄前端的连接杆可 制作成可伸缩结构， 这样可以减少旋转式杂草除根器整体体积。
所述组合刀具包括固定刀具和旋转刀具， 旋转刀具与刀杆相连， 安装在固 定刀具的前端， 在刀杆的带动下旋转； 固定刀具套装于刀杆上， 两刀具相邻面 形成剪切配合， 通过相对转动完成剪切， 使得杂草不致于缠绕于刀杆之上， 从 而降低除草的效率。
所述旋转刀具的中心具有一锥形的尖端， 并且旋转刀具的边缘具有向下延 伸的切面。 这样可以保证旋转刀具在向下旋转的过程中， 旋转刀具的中心将土 壤翻向四周， 而旋转刀具边缘的切面可以保证刀具旋转钻孔的外径， 最终达到 将杂草根部搅碎的目的。
使用的时候， 用控制手柄扶住壳体保证壳体直立， 并把组合刀具对准杂草 根部所在的位置， 打开调速开关并向下按压控制手柄， 组合刀具即可旋转并将 杂草位置的土壤翻动， 把杂草从叶到根一起搅碎， 达到斩草除根的目的。 在控 制手柄向下按压的过程中， 三角支架也会向外舒展开， 并且由于滚轮的存在， 三角支架不会伤害到附近的绿地； 当完成一个除草环节之后， 扶住控制手柄将 刀具从土壤中拔出， 三角支架在重力以及弹簧恢复力的作用下向下收紧； 而在 复位弹簧恢复力足够大的情况下， 可以通过复位弹簧的恢复力直接将刀具从土 壤中拔出。
本发明提供的技术方案， 不同于以往的除杂草设备， 采用旋转钻削的方式 将单个杂草的草叶连同草根一起搅碎， 并且由于刀具本身较小， 除杂草的过程 中， 不会对附近的绿地造成严重伤害。
与手工去除杂草相比， 本发明提供的除草设备除草效率更高， 并且除草效 果也更好。
特别指出的是， 相对于一般的除草设备对硬地草皮的除草效果， 本专利所 提供的设备可以更好的除掉硬地草皮内的杂草。 雨水过后、 阳光暴晒的草地， 很容易结起硬壳， 本专利提供的设备对这样的硬地除草效果也非常好。
附图说明
下面根据附图和实施例对本发明作进一步详细说明。
图 1为本发明所述旋转式杂草除根器的整体结构图；
图 2为所述组合刀具的组成结构图；
图 3为图 2的 A-A向视图。
图中：
1、 壳体； 2、 电机； 3、 变速器； 4、 刀杆； 5、 固定刀具； 6、 连接杆； 7、 手柄； 8、 三角支架； 9、 复位弹簧； 10、 直流电池； 11、 调速开关； 12、 充电插座； 13、 滚轮； 14、 尖端； 15、 旋转刀具； 16、 切面。
具体实施方式
如图 1至 3所示， 旋转式杂草除根器， 包括筒形的壳体 1 , 在壳体 1 内设 置有电机 2和与电机 2连接的变速器 3 , 变速器 3的头部驱动一个刀杆 4, 刀杆 4的头部安装组合刀具， 所述组合刀具包括固定刀具 5和旋转刀具 15 , 旋转刀 具 15与刀杆 4相连， 安装在固定刀具的前端， 在刀杆 4的带动下旋转； 固定刀 具 5套装于刀杆 4上， 两刀具相邻面形成剪切配合， 通过相对转动完成剪切， 使得杂草不致于缠绕于刀杆 4之上， 从而降低除草的效率。
用直流电池 10或交流电进行供电驱动电机 2带动变速器 3 , 进而通过刀杆 4带动组合刀具的旋转刀具 15旋转。
在壳体 1的尾部安装一连接杆 6, 在连接杆 6的末端安装控制手柄 7, 直流 电池 10的电源线从连接杆 6内穿过， 并在手柄 7上设置有调速开关 11和充电 插座 12。
在筒形壳体 1的前端设置有三角支架 8 , 三角支架 8与壳体 1铰接， 并在 铰轴上安装有复位弹簧 9, 三角支架 8的末端安装有滚轮 13。
所述手柄 7上设置的充电插座 12可通过充电器进行充电，手柄 7前端的连 接杆 6可制作成可伸缩结构， 这样可以减少旋转式杂草除根器整体体积。

使用的时候， 用手柄 7扶住壳体保证壳体 1直立， 并把组合刀具对准杂草 根部所在的位置， 打开调速开关 11并向下按压手柄 7 , 组合刀具的旋转刀具 15 即可旋转并将杂草位置的土壤翻动， 把杂草从叶到根一起搅碎， 达到斩草除根 的目的； 固定刀具 5卡于旋转刀具 15旋出的洞壁上， 其与旋转刀具 15的相邻 面对杂草纵向形成剪切， 使杂草不会在作业过程中缠绕于刀杆上从而影响作业 的效率。 在手柄 7向下按压的过程中， 三角支架 8也会向外舒展开， 并且由于 滚轮 13的存在，三角支架 8不会伤害到附近的绿地。当完成一个除草环节之后， 扶住手柄 7将刀具从土壤中拔出， 三角支架 8在重力以及弹簧恢复力的作用下 向下收紧； 而在复位弹簧 9恢复力足够大的情况下， 可以通过复位弹簧 9的恢 复力直接将刀具从土壤中拔出。
本发明提供的技术方案， 不同于以往的除杂草设备， 采用旋转钻削的方式 将单个杂草的草叶连同草根一起搅碎， 并且由于刀具本身较小， 除杂草的过程 中， 不会对附近的绿地造成严重伤害。
与手工去除杂草相比， 本发明提供的除草设备除草效率更高， 并且除草效 果也更好。
特别指出的是， 相对于一般的除草设备对硬地草皮的除草效果， 本专利所 提供的设备可以更好的除掉硬地草皮内的杂草。 雨水过后、 阳光暴晒的草地， 很容易结起硬壳， 本专利提供的设备对这样的硬地除草效果也非常好。
