Description
本发明涉及割草机技术设备领域,尤其涉及调高装置及包含该装置的割草机及其使用方法。
割草机又称除草机、剪草机、草坪修剪机等。割草机是一种用于修剪草坪、植被的机械工具,其有效节约了除草工人的作业时间,因此被广泛应用。目前,在园林绿化作业中,为了满足观赏需要,通常会在绿化区域内种植多种不同品种、不同高度的植被,而这些不同品种、不同高度的植被在修剪过程中与修剪的高度要求是不一样的。现有的割草机对于刀盘的高度固定,在割草机割草过程中,被切割的草会聚集在割草机的底部,并且容易缠绕在刀片上,进而影响割草机的切割、修剪质量,严重的甚至会造成刀盘、刀片损坏断裂的情况,给作业人员带来不便。
针对上述现有技术的缺点,本发明的目的是提供调高装置及包含该装置的割草机及其使用方法,以解决现有技术中的一个或多个问题。

S2:传感器400上升,割草机移动并绘制草坪边界以及回充路径。具体的,请参考图13至图21,所述传感器400上升的具体过程如下:
由第三电机401启动并带动第二齿轮403旋转,所述第二齿轮403旋转带动所述第二齿座405沿第一导向杆412的轴线方向移动,所述第二齿座405的移动通过第一轮406沿机壳5内的轨道槽501移动,随着第二齿座405的移动,在第二齿座405上半部分的第三齿座410与旋转座4221的齿4220啮合,并且向所述旋转座4221传递动力,所述旋转座4221沿逆时针方向逐步转动,并且在转动的同时导套4223在连接轴4222上向靠近固定座421的方向移动,同时导套4223的另一端带动导套安装座432以及盖板定位座433分别向靠近第一导向杆安装座427的方向移动,直至导套安装座432移动至接触第一导向杆安装座427。
请继续参考图13至图21,当导套安装座432移动至接触第一导向杆安装座427后,所述旋转座4221的齿4220此时与第三齿座410分离。由于第二齿座405持续在移动,因此第二齿座405的凸出部408上的第三槽4080也在移动,受第三槽4080斜面的影响,设置在该第三槽4080的滚轮套409开始沿第三槽4080斜面进行动作,其由第三槽4080靠近第二齿座405的一端向远离第二齿座405的一端转动,使传感器升降座415由下至上移动,移动过程中传感器升降座415四周的第二轮425均于支架411内侧的开口槽4110中自下而上的移动,进而实现传感器400从机壳5内逐渐上升。

S3:割草机内部处理单元设定割草高度,例如设定需要割草的高度在6cm。

请参考图1至图12,第一电机100启动,所述第一电机100带动第一齿轮103转动,所述第一齿轮103与第一齿座105上的齿条1051啮合,因此第一齿轮103的转动副转化为第一齿座105的移动副,所述第一齿座105沿第一齿座移动槽1145移动,由于第一齿座105上设置第一面1053,并且该第一面1053与第一滚轮106接触,因此第一齿座105的移动副再一次转化为第一滚轮106的转动副,第一滚轮106通过第一滚轮轴107连接第一连杆109,并且第一连杆109通过拉簧112与第二连杆111连接,因此第一连杆109以及第二连杆111可以同步作旋转运动,进而实现刀盘301以及刀片302的上升或下降。在本发明实施例中,所述刀盘301及刀片302下降至需要割草的高度6cm处即可。
进一步的,请继续参考图1至图12,当所述第一滚轮106滚动至第一面1053的最低位置时,此时第一连杆109以及第二连杆111相对于第一壳体114向下伸出,使刀组机构伸出所述第一壳体114,反之,当第一滚轮106滚动至第一面1053的最高位置时,此时第一连杆109以及第二连杆111相对于第一壳体114向上回收,并最终回收至第一壳体114内部。
S5:割草机移动至指定位置,例如移动至花园的起点位置。
S6:割草机绕草坪边界进行环境采集,其主要目的是采集草坪边界的环境信息。
S7:根据绘制的草坪边界开始割草作业。
S8:割草结束后根据回充路径返回充电,传感器400下降至割草机中机壳5的内部。
