改进的具自动充电销插入及拔出接触片组件的智能割草机 技术领域
本发明涉及一种用于庭院、公园及道路旁边等场所修剪草坪的草坪割草机，是具自动充电销插入及拔出接触片的充电组件的智能割草机。是在其含设在割草机底盘前部的防撞保险器以及含设有防撞保险能自停的对数螺线刹车器及设有低振动树叶吹吸机及含加装集尘袋支架及扎口及大身上壳出尘口加柔和片，吹叶轮加刃口，电路加保险和双开关，及吹吸机内外加消声减振的材料及蜂巢，滚轮改为可转向，以及把单伸出筒改为多伸出管或柔性折叠管，综合设吹吸及打草头及设有浇灌和施肥及洒药的液体管线的卷管器的多功能的割草机的基础上，再次改进的具自动充电销插入及拔出接触片组件的智能割草机，以便微量随动地插拔充电。
背景技术
草坪割草机被广泛用于按人们的喜好所选择的方式来割草。有些操作步行者喜欢和习惯用割草机时，在后半部的上扶手上使稍大的劲和有一种依靠和下压的感觉，这就无形中增加了前轮的翘起悬空的可能；而割草机的设计亦应尽可能照顾使用者的舒适和方便。使用汽油发动机的割草机前翘还少一些，因发动机较重。但也有前翘特别是左前轮前翘的不良现象发生。对于电动割草机而言，由于电动机比发动机轻，而电动机中轴要带动回转直径很大的割草刀，又不能太靠前安装，因此电动割草机的前轮翘抬现象更为常见。再说，按照有关标准例如GB4706.78-2005；IEC60335-2-77-2002；EN836-1997等标准，特别是EN836/A3-2004/4.2.3.2.1～4.2.3.2.3.3，均有斜坡16.7度的规范要求。在整机前部加配重沙壶，安装要改底盘，要加三孔位，还要加沙石，较麻烦。配重因较重，运输成本也较高。另有常见的打草机，不用刀，由串激电机带动有尼龙线的打草头。当装好打草机，并开动使绕线轮25-3内的尼龙线旋转，就能打草。当线短时，操作者墩压一下，绕线轮铝头25-3b碰地，使绕线轮弹簧25-1压缩，而使绕线轮25-3转，使其内的尼龙线134通过线眼插片25-6，而放线。放出的过长的线由刀片127修剪。不用时把刀片套126放在刀片127上，有防护作用。打草头打草效果好，比刀轻巧省电，但因需墩压放线，而无法装在有轮的普通割草机上。
通常的草坪割草机广泛采用发动机，活动范围广，但要耗油，排气污染环境。有些操作步行者喜欢用电动割草机，但受电源的限制，这种割草机的广泛采用亦受到限制。恰似汽车需要加油站一样，电动割草机也需要充电站，市场需要一种改进的具自动充电销插入及拔出接触片组件的智能割草机以便可靠地自动插拔充电；但怎样微量随动地插拔充电是个难题，发明创新构思如幽灵般在长期徘徊，借瑞士高工SENI.ENGI.毕生经验及国际协作，销球微量随动，可谓千虑而幸有一得吧，于是本发明改进的具自动充电销插入及拔出接触片组件的智能割草机就应运而生了，解决了电池不耐用需频繁人工充电的问题和微量随动地可靠插拔充电的问题。还有多处需改进，如果，想象一个装置，例如中心拉线拉动转杆，若能使绕线轮铝头放线，就能在草坪割草机上采用轻巧的打草头而省电；又如果，配重不用沙壶，也不用曾改进过的水槽，想在草坪割草机上设锂电池；最好是设进出自如卷线器；原来卷线器的阻尼有时失灵 不可靠，都知道绕线器的偶尔失灵是世界难题；幸好有刚搞出的随拉随停的绕管装置即卷线器可用，于是，一种新型的偏置的串激电机电动割草机，就是既有打草头又有卷线器的割草机，就应运而生了。其综合效果是扩大了使用范围，加强压草保墒和安全，以及省油和环保。
虽有三秒内停转割草机安规，但原用刹车可靠性不持久；因有的刹电机而带轮仍打滑；有的径向离心甩块无多齿，虽测试通过，但用久磨光就打滑；刹车过程中转动时径向仍有离心阻挠作用，若改为轴向，就无离心阻挠而刹得快；原用刹车想猛然一下闷住刹死，但因其集聚能量而事与愿违，若改闷刹为一张一弛抱刹则善莫大焉，函数波盘刹车器间歇松紧脉动而散开能量，利于刹住，且延长摩擦块的寿命，因一直压死抱着不放则摩擦块发红，而张弛松一下紧一下则摩擦块不易发红。草地里有时包藏钢硬物，而偶而伤刀或致倾覆割草机；若当前方碰撞活支架的外包橡胶皮而使活支架的滑杆回缩时而触发限位开关，可利防撞。防撞保安及确保刹车，割草打草可选，有电线而区域大，这些说着容易做着难，一直是电动割草机的老大难问题。
为什么要用卷线器？因为很长的散乱在地上的电线，在电动割草机往返割草时，有时不小心就被脚踩到，或被轮压到，影响安全；有时又会因电线打结或乱缠，致使线不够长而暂停割草，或由人手去理线，增加了安全隐患。为什么要把卷线器装到电动割草机上？用过电动割草机的人都知道，割草时常有漏草，就得重割，特别是在环境复杂如有树丛夹杂在草坪时，就需要进几步推几步及左右多次重复割草；如果卷线器放在很远处，割草机附近的电线并不能及时随拉随停同步进出，还是会软沓沓掉地上，有被踩到或被轮压的危险，或不能及时进出线。把卷线器装到电动割草机上，不但为了代替配重，而且为了进退自如，所述的卷线器在割草机的前部和中部的两种装法，其出线口都距地面较高，故不易被踩到或被轮压。
若把卷线器改用水管就是卷管器；割草机一年里大部分闲置，若在割草机上装卷管器，管里装水能浇灌；管里装药水能防虫；管里装肥料水能施肥；若能一机多用该多好。
吹吸机被广泛用于按人们的喜好所选择的方式来清理树叶。有些操作步行者喜欢和习惯用吹吸机时，特别是遇到边角地方时，左顾右盼和转过角度来吹吸，若把接触地面的滚轮改为可转向，将可方便工作；操作步行者的身高不同，以及习惯采取工作角度的不同，需要辅助手柄可调节，而原有的固定辅助手柄不够称手。供电源的保险因供多路，而往往对一个吹吸机不适合，而原吹吸机内电路缺超荷防护，若加保险及双开关，将会更安全。低振动性和低噪音，亦有进一步优化的必要；若考虑在马达外加减振动的泡沫塑料及在吹吸机的多处加减震消声材料和蜂巢结构，可有一定疗效；而打草机的振动和噪音的很大根源在动力和工具的精度与形位公差，若采用提高马达和吹叶轮同轴度，及测动平衡的改进方法，当是希望的，但追求吹吸机的低振动低噪音，事实上是一项长期遗留的老大难问题。集尘袋支架及扎口，装多了易滑落，亦须改进；吹吸机大身上壳出尘口，有时特别是换向时风猛，需加柔和片；吹叶轮加刃口，对切割易堵的大吸入物当有作用；以及若把单伸出管改为多伸出管或柔性折叠管，可进一步缩小体积，提高运输工效。吹吸机由操作步行者拿着背着总是很重，且集聚袋很小，动力电池小，工作时间短。若把吹吸机放到割草机上，由扛着到有轮子滚着是个技术进 步，不但减轻人的负担，而且割草机上集草袋能大很多，连续工作时间长。

有益之处：改进的具自动充电销插入及拔出接触片组件的智能割草机能自动插拔充电；其特征在于，所述充电销((233)的根部所设有的销球(233a)，是在球形座上设有十字架销，解决了微量随动地可靠插拔充电的难题。恰似汽车需要加油站一样，电动割草机也需要充电站，市场需要自动充电销插拔的智能割草机，解决了电池不耐用需频繁人工充电的问题；其水平铺于地表的底板的左侧及右侧各所设有的沿中轴线对称的导向轨(233c)的每个导向轨的曲线段是立方曲线，以便减缓冲击；所述的接触片(234)的接触面((234b)的一段曲线是对数螺线，因对数螺线即等角螺线具有压力角处处相等的特性，利于接触插入。所述接触片(234)及压片扭簧(234a)以及转轴各共有四个，形成面对面的对开的双门，左侧和右侧各有所述的双门的活动门的面对面的每个所述的接触片(234)的接触面((234b)对应所述的立于前方的前墙上所设有的沿中轴线对称的左侧及右侧各一的所述的充电销((233)的头部所设有的所述的插入面(233b)，以便充电销插入，当充至设定值时会启动割草机后退，使充电销拔出接触片去割草；当又要充电时割草机行走到底板上，以此往复。用立方曲线和用对数螺线是技术进步。自充电 割草机用处较多：一机吹吸割草多用。增强了防撞保险及刹车效果，割草打草可选，活动区域超大；在割草机上设蓄锂电池，设进出自如卷管器；有多阻尼，解决了卷线器有时偶失灵的难题；新增碰撞回缩触发限位防撞功能，加强配重以利压草保墒，斜坡16.7度安全不倾倒，在整机前部省配重，使割草机前翘而达标，使用者舒适和方便，不用内燃机而省油节能和有利RoHS排放环保；防撞保安及张弛抱刹能确保刹车，有利防撞而解决草地里有时包藏钢硬物而偶而伤刀或致倾覆割草机的难题；加蓄电池及进退自如随拉随停的卷线器成倍扩大割草范围；函数波盘刹车器的一张一弛抱刹是个创新，其刹车器还设有轴向的按函数渐趋抬高的摩擦块的轴盘，及设有内部的多内齿的带轮，以及有多弧齿的径向离心甩块，可适于多种机型，发明改闷刹聚能为张弛抱刹，间歇脉动而散开能量的刹车新理念是一个创举；防撞保险，确保刹车，能割能打，进退自如，这些说着容易做着难；用中心拉线拉动有迷宫的转杆使绕线轮放线，从而打破了打草头尼龙线切割装置无法用于割草机的历史，且异型多槽尼龙线亦有利切草锋利而节能和降噪；又由于采用带有多种而不是单个阻尼机构的绕线装置，多种互补更可靠，即由离心慢回缩装置，侧活塞阻尼装置，位置锁及球位置锁，逆阻机构，排管器角度槽式阻尼机构所互补的卷管器，从而大大增加了割草范围；或许可以说，其开创了一种有浇灌和施肥及洒药以及防撞对数螺线自动抱刹的割草机的新领域；而发明函数波盘改闷刹聚能为张弛抱刹，间歇脉动而散开能量的刹车新理念亦作为一种创举的刹车方法而用之于多种领域；有自动抱刹防护的对数螺线刹车器的割草机，因其刹车器制动杆的弧形有对数螺线的一段具有压力角处处相等的特性，形成实质的有凸轮结构的刹车器，已批量生产，解决了不容易使割草刀急停而符合安规的难题。卷管器的管内的液体肥料是水里加有可溶化的按百分比的农药或肥料易于更换。本发明的有益之处还在于，卷线器使割草打草活动区域超大；卷管器换液体能洒药施肥灌溉；在草坪割草机上设蓄电池，设进出自如卷线器；巧妙多阻尼，可解决卷线器有时失灵的世界性难题；新增碰撞回缩触发限位防撞功能，加强配重以利压草保墒，斜坡16.7度安全不倾倒，在整机前部省配重，使割草机前翘而达标，使用者舒适和方便，不用内燃机而省油节能和有利RoHS排放环保；防撞保安及张弛抱刹能确保刹车，有利防撞而解决草地里有时包藏钢硬物而偶而伤刀或致倾覆割草机的难题；加蓄电池及进退自如随拉随停的卷线器成倍扩大割草范围，可解决电动割草机受电源限制而难广泛采用的问题；函数波盘刹车器的一张一弛抱刹是个创新，其刹车器还设有轴向的按函数渐趋抬高的摩擦块的轴盘，及设有内部的多内齿的带轮，以及有多弧齿的径向离心甩块，可适于多种机型，发明函数波盘改闷刹聚能为张弛抱刹，间歇脉动而散开能量的刹车新理念是一个创举；防撞保险，确保刹车，能割能打，进退自如，这些说着容易做着难，一直是电动割草机的老大难问题；无人预知何时出现，有时失灵就是老大难问题，诚如人类想万无一失，永不翻车，追求完美的发明是永无止境的；用中心拉线拉动有迷宫的转杆使绕线轮放线，从而打破了打草头尼龙线切割装置无法用于割草机的历史，且异型多槽尼龙线亦有利切草锋利而节能和降噪；又由于采用一种带有多种阻尼机构的绕线装置，多种互补更可靠，即由离心慢回缩装置，侧活塞阻尼装置，位置锁及球位置锁，逆阻机构， 排管器角度槽式阻尼机构所互补的卷线器，从而大大增加了普通有电线的电动割草机的割草范围；或许可以说，其开创了一种有底盘防撞保险带函数波盘刹车器的既有打草头又有卷线器的割草机的新领域；而发明函数波盘改闷刹聚能为张弛抱刹，间歇脉动而散开能量的刹车新理念亦能作为一种创举的刹车方法而用之于多种领域。

具体实施方式
先建电脑3D模，再刻模具；再在割草机上加防撞和刹车，其技术方程式及建模方法是：
采用PRO/ENGINEER WILDFIRE绘图软件，新设工作目录，新建零件，草绘2个同心圆。
打开可变截面扫描(Var Sect Sweep)指令，选取以上2圆为扫描轨迹和参考轨迹。
绘制一条平行2圆平面的直线，长度L＝(D-d)/2，且对应圆边沿投影线。
建立参数(PARAMETER)1：C实数(real number)，可跟据具体工况在0.01-1之间赋值，例如0.3；C也称为波高。建立参数(PARAMETER)2：N整数(integer)，跟据具体工况在2-100之间选值，例如13；N也称为波数。建立关系(RELATION)，如本发明的正弦波方程式是：电脑默认SDi＝C*SIN(TRAJPAR*360*N)；上式中，i是尺寸数字序列号；SIN＝SINE，正弦函数；TRAJPAR，轨迹函数。再采用旋转，合并，实体化等指令，即建模为函数波盘。
再用所述的方程式输入CNC加工中心，用CIMATRO或MASTCAM制钢模，或用铣床，刨床及电火花加工。用电火花加工时，用所述的方程式输入CNC加工中心，则要先制出钨铜电极。
制造方法有多种；或用压铸铝合金的制造方法，用有冷压室的压铸机批量生产函数波盘，基底材料是铝合金ZL109，或AC8A，并添加耐摩擦料。或用压铸锌铝合金的制造方法，用有热压室的压铸机批量生产，基底材料混乱添加耐摩擦料。或用制出的函数波盘成型芯制作模具，而先作成多个蜡模芯，然后再用蜡模铸造法大量铸出函数波盘铸件。
特别需要指出的是，本发明的函数波形也可采用其它的多种数学函数与粗糙凸凹组合，或其它的非陡峭折线的略为圆滑的波形。
操作步行者用有吹吸机的割草机，最好戴上防护眼镜和口罩，还要把肩带43接到操纵把手上和机壳上；拉出吹吸的伸缩管，调节转速，调好辅助手柄；检查电源，配上锂电池或电源长线，再次检查保险，按使用说明书，试开一下，查看有树叶区无碎玻璃及电线，在安全的情况下才可用有吹吸机的割草机来做，同时须注意天气下雨情况。
本发明是通常的用于庭院、公园及路旁等场所修剪草坪的割草机的重大改进，主要改进是草坪割草机前部设有可活动抽出的放置蓄电池的支架；割草机中部设有的切割装置由不装在该中心而是偏置的串激电机所拖动的；切割装置可用两种，一种是有风扇塑料刀座的刀，另一种是把原打草机上转轮内的绕线轮的尼龙线移植到割草机上；因偏置的串激电机让出了中心轴位置，才能用本发明的中心拉线拉动转杆，使绕线轮铝头放线，从而打破了打草头尼龙线切割装置无法用于割草机的历史；又由于采用一种带有多种阻尼机构的绕线装置，即由离心慢回缩装置，侧活塞阻尼装置，位置锁，活板压簧阻尼机构，逆阻机构，排管器角度槽式阻尼机构所互补的绕线装置，从而大大增加了普通有电线的电动割草机的割草范围。或许可以说，开创了一种既有打草头又有卷线器的割草机，这样一种新技术领域。其有益之处是解决配重，电源及割草诸问题。
一种串激电机电动割草机，是既有打草头又有卷线器的割草机，主要是在普通的草坪割草机上加设有三大总成，即设有蓄电池支架总成，设有串激电机所拖动的设在割草机中部的有拉动转杆和打草头的切割装置总成，以及设有卷线器总成；所述的支架，是在草坪割草机前部设有可活动抽出的放置蓄电池的支架；所述的切割装置有两种，一种是在割草机中心的割草刀上，设有塑料风扇的刀座，以便导风和绝缘；另一种是把原打草机上转轮内的绕线轮的尼龙线移植到割草机上，因偏置的串激电机让出了中心轴位置，才有可能使中心轴空心，才能用本发明的中心拉线拉动转杆，使绕线轮放线；实用时最好按草杆草况试配切割装置；所述的卷线器安在割草机的前部或中部，解决配重和电源；以下分别予以详述：

所述的串激电机电动割草机中部设有的切割装置总成，是由不装在该中心而是偏置的串激电机所拖动的；切割装置可用两种，一种是有风扇塑料刀座的刀，另一种是把原打草机上的打草头的转轮内的绕线轮的尼龙线移植到割草机上；因偏置的串激电机让出了中心轴位置，才能用中心拉线拉动转杆，使绕线轮铝头放线，从而打破了打草头尼龙线切割装置无法用于割草机的历史；所述的串激电机电动割草机用的有风扇塑料刀座的刀，是在割草机中心的割草刀上，设有塑料风扇的刀座，参看图12，所述的刀座85上设有花键槽85a，以便与大带轮82的花键82a相配合，以便在偏置的串激电机的带动下使刀座的刀割草；所述的刀座85上设有多个风扇85d，以便导风；且所述的风扇上设有多个小通孔85c，最好是六角形孔，以利降噪；而且所述的风扇上设有刃口85b，以利防缠草；所述的刀座宜用不导电材料，例如尼龙加纤塑料。
所述的串激电机电动割草机中部设有的切割装置总成，是由不装在该中心而是偏置的串激电机所拖动的；切割装置可用两种，一种是有风扇塑料刀座的刀，另一种是把原打草机上的打草头的转轮内的绕线轮的尼龙线移植到割草机上；因偏置的串激电机让出了中心轴位置，才能用中心拉线拉动转杆，使绕线轮铝头放线，从而打破了打草头尼龙线切割装置无法用于割草机的历史；所述的串激电机电动割草机中部设有的有打草头和中心拉线拉动转杆的切割装置总成，参看图4和图5，由内机架76，串激电机77，电机皮带轮84，皮带83，大皮带轮82，拉线81，拉动转杆78，推力轴承79，有迷宫的拉转架80，及打草头所组成；而所述的打草头，又被称为含线盒底座的盘绳打草总成，可参看图10，由打草头壳24-3，绕线轮弹簧25-1，绕线轮25-3，尼龙线134，护线圈123，线眼插片25-6，线盒上盖25-7所组成；所述的刀片127设在割草机割盘的圆周上，不用时把刀片套126放在刀片127上，有防护作用；原来用坚固的绕线轮铝头25-3b，当线短时，操作者墩压一下，绕线轮铝头25-3b碰地，使绕线轮弹簧25-1压缩，而使绕线轮25-3转，使其内的尼龙线134通过线眼插片25-6，而放线，放出的过长的线由刀片127修剪；现改为不用墩压碰地，故可省掉绕线轮铝头25-3b，而是用中心拉线拉动转杆，使绕线轮放线；放出的过长的线由刀片127修剪；所述的尼龙线134，最好用一种打草机异形多槽线，所述的异形线的特征是其截面上开有槽口34a，最少一个，或多个，例如3个；所述的槽口是沿尼龙线呈螺旋形的，且沿圆周成等分均布的；所述的槽口是三角形的，以利割草；所述的内机架76，装割草机底盘的割盘的上方，在偏置的串激电机77的轴上，设有电机皮带轮84，并通过皮带83，驱动中心线在底盘的割盘中心的大皮带轮82；所述的大皮带轮82驱动所述的打草头；所述的大皮带轮82与打草头壳24-3，线眼插片25-6，线盒上盖25-7依次相连，在打草头壳24-3内通过绕线 轮弹簧25-1，压装有绕线轮25-3，所述的绕线轮25-3上装设有尼龙线134，及护线圈123；所述的拉动转杆78与所述的绕线轮25-3连接，或固连，或用轴档圈，或用反丝扣，或用推力轴承相连；所述的拉动转杆78的另一端，通过推力轴承79，而与有迷宫的拉转架80相连，所述的拉转架80上套装有所述的拉线81的钢丝绳的一端头，而拉线的另一远端头与割草机大扶手边的放线操纵杆81b相连；当放线时，拉线拉动转杆，参看图7，使绕线轮上的几个凸台上移，而与线盒上盖25-7的几个孔坑脱开，绕线轮相对于打草头壳转动而放一下线；当打草时，整个打草头同转，绕线轮相对于打草头壳不转动就不放线；所述的有迷宫的拉转架80，是方框形，以利不易变形，因用单边的日久易拉得变形；其下面设有拉动转杆的孔80c，以便放推力轴承79和插入杆，其侧面设有长孔80b，以便放进拉线头；其上面设有中心孔80d以便放拉线，特别是其上面设有迷宫80a，其有多个弯路，连接所述的长孔和中心孔，以便拉线的钢丝绳的粗大的一端头先通过长孔80b放进拉转架80的方框，再把拉线的钢丝绳沿迷宫80a的多个弯路绕道而行进入中心孔，从而不易松脱。
所述的串激电机电动割草机的电路图，如图2所示，主要由保险RC，开关K，电感L3，电感L4，电容C，及设有绕组L1和绕组L2的串激电机M，以及起动按纽AQ和把柄75，及二极管Di，电阻R1，R2，发光管LED，绕线器及插头插座所组成；本发明特意加有保险RC，其用保险丝，或用热继电器，或用过流保护器，以求更安全；为什么供电源内已有保险，还要加保险？因为供电源还供多处，其保险往往太大，并不刚好适合本割草机。
参看图15，图16及图1，所述的起动按纽AQ和把柄75的头部，及二极管Di，电阻R1，R2，发光管LED，开关K及插头，以及各件各自的复位弹簧，均装在割草机扶手架的带把柄75的插头座75b上；所述的把柄75的头部设有勾头；所述的起动按纽AQ设有长薄片QA2，且通过长薄片连着压块QA1，还设有限位片QA3；当按下起动按纽AQ，并扳动把柄75时，所述的把柄75的头部设有的勾头压着起动按纽AQ的压块QA1，并使起动按纽AQ的压块QA1压着开关K，才能起动；当要关时，只要扳动把柄75，各件各自就可弹性复位；所述的二极管Di，电阻R1，R2，发光管LED仅仅是个指示灯的作用；所述的卷线器的一端接电源，卷线器的另一端可与带把柄75的插头座75b上的插头相接，并通过开关K接马达。
操作者选择将一种带有多种阻尼机构的绕线装置即由轮壳总成，离心慢回缩装置，侧活塞阻尼装置，位置锁，以及逆阻机构和排管器上的角度槽式阻尼机构所组成的绕管装置的外壳上的通过长销18连接且可在180度内微转的支架19放置在割草机的前部或中部的方式来装配；如图1或图3所示；也可在割草机的前部设一根垂直轴，并在支架19的中部设孔套在垂直轴上来装配；或者，在割草机的中部设一根垂直轴，并在卷线器的中轴部设孔，套在垂直轴上来装配；并插接好电源和予以固定；操作者在割草掉头时，最好让线从割草机前面转向，而不要从割草机后面转向，就是说要注意不要拌脚即可。根据草地混杂及远近情况，操作者还可选择用几个或那几种阻尼机构的绕线器，因在固定的大齿轮4的周围，有空间可放置多个小齿轮9来连接多个阻尼机构和位置锁。或者可换用所述的锂电池。因为所述的轮壳总成由上壳13，上大盘12，盘簧发条11，内盘5，大齿轮4，主轮14，接头15，下盘16，下壳17，长销18，支架19所组成。所述的外壳的中心轴的孔装有设有转轴的 下盘16及内盘5；内盘5通过盘簧发条11与上大盘12组成回缩装置；在内盘5上插入上小内盖21，而且再通过上小外盖22固定按装在上壳13上。不动的内盘5的轴上的槽上固装着盘簧发条11的靠近圆心的一端，所述的盘簧发条的外圈装配在转动的主轮14的边缘处的卡柱上，并用上大盘12通过边缘的四处卡位盖住。所以大齿轮不动。当操作者拉动管线时，因为主轮14上装配有线接头15，在线接头上已按装管线并把管线穿过排管器的2个滚轮而绕好在主轮上，且主轮14与下盘16通过螺丝固定连成一体，且由下盘16的中心大管轴转动地活套插到下壳17的中心大管的光滑的外轴表上，故上大盘12，主轮14，管接头15，下盘16相对于外壳是转动的；由小齿轮9和转盘6带动拐把销10的一端30沿阻尼盒壳3的底面的凸轮类槽内运行；停拉时，拐把销的销端30因发条反作用会锁定；再拉点并松开，销端30沿外圈槽无锁，软管或缆线在发条11的反作用力下，自动回卷；若过快时，高速的象行星轮效果的小齿轮9使小滑块1离心伸出，与壳边及与小活塞7接触而阻尼。所述的由拉簧2互拉且沿阻尼转盘6的滑道6a伸出的小滑块1，特别是小滑块1的桃形体的渐开线面及抛物线面，鱼贯地与小活塞7及阻尼盒壳3内部碰撞，啮合，滑动，磨擦，诸多作用加强了慢回缩阻尼功效。
不断新构思的方案是在已使用的卷线器内，利用中间的不动的大齿轮4，在其周围可多装小齿轮9来转动的特点，加装另一个阻尼盒壳，或者代替已用的慢回缩阻尼装置，本发明亦可称为有活板压簧机构及多阻尼机构的绕先装置，故加装几个阻尼盒，是按客户要求和产品型号所要求的性能来选的。又因为所述的活板压簧机构由小齿轮9，由小齿轮9所带动的密螺纹轴64，活板61，压簧62，阻尼盒壳63，阻尼盒盖65组成；其特征是：所述的密螺纹轴64上设有螺纹；螺纹最好采用细牙标准螺纹，其细牙有利于缩短轴行程，其标准螺纹有利于加工；所述的活板61设有内螺纹，以便与密螺纹轴64相联动而上下移动；所述的活板61设有多个外凹槽，最好是4个，以便与阻尼盒壳63内的多个凸导轨63a相滑动；所述的活板61下装有所述的压簧62，压簧62的另一端与阻尼盒壳63的盒内接触；所述的阻尼盒壳63装配在主轮14上；所述的阻尼盒盖65装配在阻尼盒壳63的上面，故当主轮14回缩时，小齿轮9所带动的密螺纹轴64使活板61下移，使压簧62多加压于阻尼盒壳63的盒内，起到阻尼作用；又当主轮14在管线拉出而反转时，小齿轮9所带动的密螺纹轴64使活板61上移，使压簧62少加压于阻尼盒壳63的盒内；如此周而复始，形成有压簧机构的多阻尼机构的绕线装置。
在另一个阻尼盒壳里，设有相同的另一小齿轮9驱动的螺旋轴106，以螺旋角大于23.5度的螺旋与内螺旋磨擦轮105联接；当轴正转时轮下移磨擦壳底，反之上移；形成阻尼器的螺旋磨擦式单向机构的阻尼效果。
同时，在加装的另一个阻尼盒壳里，在大齿轮4的外围多设的几个相同的其中之一的小齿轮9的驱动下，逆阻转盘23转动；带有多种阻尼机构的绕线装置的逆阻机构，由逆阻转盘23，逆阻转块24，扭簧26，销轴25，小齿轮9所组成。所述的逆阻转盘的安放销轴25的多个特别是4个均布的孔23c内插入的销轴25套装着的活动的逆阻转块24，平时在安放扭簧的多个特别是4个均布的小孔23b内插入一端的扭簧26及其扭簧另一端的作用下，其逆阻转块24的小弧面24c不碰触阻尼盒壳的内壁，而是逆阻转块24的弦面24d靠近内壁，这就是说正向拉出 时无阻，逆阻转块24的限位突24a与限阻转盘的限阻块23a相配和。但当逆向回缩时，逆阻转块24在速度快时就会受向心力的作用而发生离心偏转致使逆阻转块24的小弧面24c碰触阻尼盒壳的内壁，造成逆阻效果。
因为设在绕线装置的上壳13，下壳17的出口处的排管器53的安放2个滚轮轴芯盖54的导向器后支架51的2个孔，均被改为如图29所示的互有角度a的长圆槽，这样就组成了所述的滚轮轴芯盖的2个轴心在管被拉出时沿角度槽51a较远即滚轮松，而拉进时沿角度槽51b较近即滚轮紧的可变松紧的角度槽式阻尼机构。当操作者拉出线时，滚轮受到向外的磨擦分力，使得安放滚轮55的滚轮轴芯盖54被拉出时沿角度槽51a近；又因为所述的排管器53的导向器后支架51的角度槽内安放的滚轮轴芯盖54，可参看图24，由原来的2个轴心的定距，改为动距；每个盖的圆周的外側设有的拉块54a和每个拉块设有的小拉簧孔54c，被一个拉力较小的拉簧54b的两端分别插入所述的小拉簧孔中所轻轻拉住；所述的滚轮轴芯盖内安放2个滚轮55，且两个滚轮间安装有活动的管线；所述的排管器53的导向器前支架52和导向器后支架51合起来就组成了安放滚轮轴芯盖的角度槽即如图23所示的互有角度a的长圆槽，这样就形成了所述的滚轮轴芯盖的2个轴心在管被拉出时沿角度槽51a较远即滚轮松的效果。而线回缩时，由于角度槽内安放滚轮轴芯盖(如图23所示)的互有角度a的长圆槽的角度a在1度到23度之间，又由于考虑到管线进盘后是向左拐，而使所述的互有角度a的两条边，其分别与垂线的夹角，是左夹角β小于右夹角γ，所以回缩管时，滚轮受到向内的磨擦分力，使得安放滚轮55的滚轮轴芯盖54被拉进时沿角度槽51b近，安放滚轮轴芯盖的角度槽使滚轮轴芯盖的2个轴心靠近，这样就形成了沿角度槽51b较近即滚轮紧的可变松紧的角度槽式阻尼机构。
因为本发明的有球位置锁及多阻尼机构的绕管装置解决其任意位置锁的问题的技术方案可称为有球位置锁，技术革新的关键在于球；新构思的方案是在已使用的卷线器内，利用中间的不动的大齿轮4，在其周围可多装小齿轮9来转动的特点，加装所述的有球位置锁及多阻尼机构的绕管装置，其有球位置锁由小齿轮9，由小齿轮9所带动的锁芯轴74，球70，扭簧73，锁芯72，位置锁盒壳71组成；所述的位置锁盒壳71装配在主轮14上，所述的扭簧73套在锁芯轴74上，且常态是包紧套上的；所述的锁芯72活套装在所述的扭簧73及锁芯轴74并装入所述的位置锁盒壳71内；所述的锁芯72设有偏心的心形锁槽，偏心以便槽内球顺向移动，心形的凹进底部是当球进入时为锁的位置；其特征是：所述的球70是光滑的，最好是钢球；又因为球70具备按六个自由度，即三个平动自由度及三个转动自由度的特性，所以活动时，球就比拐把销或锁针有更少的分向扭力矩，而更不易偶尔卡住。所述的扭簧73是密圈的，截面是圆形的，便于加工其多弯曲的L形端部73a和U形的端部73b，也便于工作时不易因方形扭转的棱边而磨损芯轴。又因为所述的扭簧73其端部73a是呈L形的，故以利于卡在所述的锁芯72上方；而另一端73b是呈U形的，有两个边，故利于所述的球70的推动；且因所述的扭簧73的端部73a卡在所述的锁芯72上，而所述的扭簧73的端部73b伸出到锁芯72的心形锁槽的靠近心尖部的方孔内，且与所述的球70相接触；所述的球70活动安装在位置锁盒壳71的轴向长槽71a和锁芯72的心形锁槽内，并与套装在锁芯轴74且伸出到锁芯72的扭簧73的端部 73b相接触，以便与锁芯72的心形锁槽相联动而随所述的位置锁盒壳71的轴向长槽71a而上下移动，其目标是当所述的球70推所述的扭簧73的端部73b到位而使扭簧密圈的内径变大，以松开由小齿轮9所带动的锁芯轴74，使管线自由；而当所述的球70落到锁位不推所述的扭簧73的端部73b，而使扭簧密圈的内径变小，以包紧由小齿轮9所带动的锁芯轴74，使管线不动；从而形成有球位置锁及多阻尼机构的绕线装置。当操作者拉动管线时，因为主轮14上装配有接头15，在接头上已按装线并把线绕好在所述的主轮上，主轮14与下盘16通过螺丝固定连成一体，且由下盘16)的中心大管轴转动地活套插到下壳17的中心大管的光滑的外轴表上，故上大盘12，主轮14，管接头15，下盘16相对于外壳是转动的；当拉出管线时主轮14带动小齿轮9。停拉时，所述的球70，因发条反作用，会沿所述的锁芯72设有的偏心的心形锁槽(偏心以便槽内球顺向移动)，而碰到心形的凹进底部，球进入时为锁的位置，处于锁定；再拉点并松开管线，无锁，软管或缆线在发条11的反作用力下，自动回卷。在某些情况下，如左右转动角度过大，在卷线器的轴中部，或在前述的作安装用的垂直轴上，均可设双滑环带碳刷的接头，以利保护某些经铜铝导线布氏试验而偏硬的电线。
因在电动割草机上，设在割草机底盘前部的防撞保险器设在所述的支架总成的所述的活支架(90)上，由装设在割草机底盘的支架座的定滑座(90c)，及可拉出的设有滑杆(90a)和限位(90b)的活支架(90)所组成，所述的活支架(90)的滑杆(90a)套装在所述的支架座的定滑座(90c)内，当被拉出时由限位(90b)定位，其特征在于所述活支架(90)是外包橡胶皮的，且所述的限位(90b)设有限位开关，以便当前方碰撞所述活支架(90)的外包橡胶皮而使所述的活支架(90)的滑杆(90a)回缩时而触发所述的限位(90b)设有的限位开关，以形成防撞保险器而保险；所述的设在割草机底盘中部的刹车器的串激电机电动割草机的割草机底盘中部的刹车器，含内机架(76)，装在割草机底盘的割盘的上方，所述的内机架上装设偏置的串激电机(77)，在偏置的串激电机(77)的轴上，设有电机皮带轮(84)，并通过皮带(83)，驱动中心线在底盘的割盘中心的带轮(204)；并离合连接其同轴心的输出轴(203)，所述带轮(204)上面用机牙螺(216)固定一作制动用的函数波盘刹车片(206)；内机架(76)上固定一个制动固定板(207)，用六角螺钉(218)和六角螺母(219)相互固定；制动固定板(207)上设有一个活动的制动杆(208)，通过铆钉(215)连接，可灵活转动；制动杆(208)上设有摩擦片(209)，用实铆钉(223)连接，通过作用于制动固定板(207)和制动杆(208)上的制动拉簧(210)使摩擦片(209)与带轮(204)上的作制动用的函数波盘刹车片(206)制动张紧；制动杆(208)用一条拉索(211)与操纵手柄相连接，以便刹车离合；当启动拉杆启动机器的过程中，拉索带动制动杆转动，使摩擦片与制动板分离，此时制动拉簧被拉长，使制动拉簧积聚弹力，当启动拉杆释放后，电源被切断，皮带轮失去动力，制动拉簧释放弹力，使摩擦片张紧制动板，使皮带轮停止转动，实现刹车功能。所述有自动抱刹防护的对数螺线刹车器的串激电机电动割草机，其特征在于，其设有对数螺线刹车器；其特征还在于，其设有能用于浇灌和施肥及洒药的通过液体的管线的卷管器；所述的 刹车器，含内机架(76)，所述的内机架上装设电机(77)，在所述电机(77)的轴上，设有电机皮带轮(84)，并通过皮带(83)，驱动中心线在底盘的割盘中心的带轮(204)；并离合连接其同轴心的输出轴(203)，所述输出轴(203)连接工作刀具如割草刀；所述带轮(204)上面用机牙螺钉(216)固定着制动拉簧(210)的一端，所述制动拉簧(210)的另一端连接着作制动用的制动杆(208a)的回位拉孔(225)；所述制动杆(208a)上设有转动孔(226)并通过铆钉连接在带轮(204)内且可灵活转动；所述制动杆(208a)上设有摩擦片(209)；所述的内机架上装设有固定的刹车环(201a)；所述输出轴(203)的外部套装有同轴的突块拨盘(227)；所述突块拨盘(227)的边缘处设有突块拨座(224b)；所述突块拨盘(227)的边缘处还设有复位座(228)，以便安装复位压簧(228a)而复位；所述突块拨座(224b)上装配有突块组件(224a)；所述制动杆(208a)上设有依次由上圆弧(224d)、槽边(224)、下圆弧(224c)、又一条槽边(224)所围成的挖空的弧形槽；所述上圆弧(224d)是半圆弧，且其圆心到所述输出轴(203)轴心的距离远于亦是半圆弧的所述下圆弧(224c)的圆心到所述输出轴(203)轴心的距离，从而使所述弧形槽的槽边(224)不顺着沿输出轴轴心的同心圆周，而是偏心，这就形成实质上的凸轮；把所述突块拨盘(227)上的突块组件(224a)插入到所述弧形槽且顺所述槽边(224)滑动，这就形成实质上的凸轮结构；因串激电机停转时，虽串激电机内有电磁急停，但割草刀惯性大难急停，为了使割草刀急停以符合安规，就需要刹车器；当串激电机停转时，由电机带动的所述带轮(204)停转，则所述制动杆(208a)失去向外甩开的惯性离心力，以所述转动孔(226)并通过铆钉而转动，且由所述制动拉簧(210)连接着的制动杆(208a)的回位拉孔(225)而转回位，就使所述制动杆(208a)上设有的摩擦片(209)抱刹所述的内机架上装设有的固定的刹车环(201a)；在所述制动杆(208a)转回位的同时，因所述制动杆(208a)上设有依次由上圆弧(224d)、槽边(224)、下圆弧(224c)、又一条槽边(224)所围成的挖空的弧形槽；且因所述上圆弧(224d)是半圆弧，且其圆心到所述输出轴(203)轴心的距离远于亦是半圆弧的所述下圆弧(224c)的圆心到所述输出轴(203)轴心的距离，使所述弧形槽的槽边(224)不顺着沿输出轴轴心的同心圆周，而是偏心，这形成实质上的凸轮；把插入到所述弧形槽且顺所述槽边(224)滑动的所述突块拨盘(227)上的突块组件(224a)依实质上的凸轮结构原理从所述上圆弧(224d)压推向所述下圆弧(224c)，因所述输出轴(203)的外部套装有同轴的突块拨盘(227)，从而使所述输出轴(203)连接着的工作刀具如割草刀停转；反之，当串激电机在转动时，由电机带动的所述带轮(204)转动，则所述制动杆(208a)受到向外甩开的惯性离心力，以所述转动孔(226)并通过铆钉为支点而转开，就使所述制动杆(208a)上设有的摩擦片(209)离开所述的内机架上装设有的固定的刹车环(201a)，同时，因所述突块拨盘(227)的边缘处还设有复位座(228)，方便安装好的复位压簧(228a)复位。更加改进完善的所述的有自动抱刹防护的对数螺线刹车器的串激电机电动割草机，其特征是：所述的内机架上装设的固定的刹车环(201a)是金属的，以利耐热和耐磨性；且所述刹车环(201a)有多个凸出的翻边，以利卡牢 。所述制动杆(208a)上设有的摩擦片(209)的弧形是对数螺线的一段。所述突块拨盘(227)的边缘处设有的突块拨座(224b)上设有通孔以及方形凹坑，以便安装所述突块组件(224a)。所述突块拨盘(227)上所安装的所述突块组件(224a)含螺栓和螺帽及滑套。所述突块拨盘(227)上所安装的所述突块组件(224a)含螺栓和螺帽及滑套和轴承。所述突块拨盘(227)所设有的复位座(228)是突出的十字架形，以牢固安装复位压簧(228a)。所述制动杆(208a)上设有依次由互为接连处正交及相切或圆滑的上圆弧(224d)、槽边(224)、下圆弧(224c)、又一条槽边(224)所围成的挖空的弧形槽。所述制动杆(208a)上所设有的挖空的弧形槽的槽边(224)的弧形是对数螺线的一段，故任何位置压力角相等不卡死。所述的有浇灌和施肥及洒药以及防撞对数螺线自动抱刹的割草机的卷管器的管内装有的用于施肥的液体肥料是水里加有可溶合的按百分比的肥料；或换用液体农药或喷雾用水，故易于一机多用。
本发明的有益之处是：增强了防撞保险及刹车效果，割草打草可选，活动区域超大；在草坪割草机上设蓄锂电池，设进出自如卷管器；有多阻尼，解决了卷线器有时失灵的世界性难题；新增碰撞回缩触发限位防撞功能，加强配重以利压草保墒，斜坡16.7度安全不倾倒，在整机前部省配重，使割草机前翘而达标，使用者舒适和方便，不用内燃机而省油节能和有利RoHS排放环保；防撞保安及张弛抱刹能确保刹车，有利防撞而解决草地里有时包藏钢硬物而偶而伤刀或致倾覆割草机的难题；加蓄电池及进退自如随拉随停的卷线器成倍扩大割草范围；函数波盘刹车器的一张一弛抱刹是个创新，其刹车器还设有轴向的按函数渐趋抬高的摩擦块的轴盘，及设有内部的多内齿的带轮，以及有多弧齿的径向离心甩块，可适于多种机型，发明改闷刹聚能为张弛抱刹，间歇脉动而散开能量的刹车新理念是一个创举；防撞保险，确保刹车，能割能打，进退自如，这些说着容易做着难；用中心拉线拉动有迷宫的转杆使绕线轮放线，从而打破了打草头尼龙线切割装置无法用于割草机的历史，且异型多槽尼龙线亦有利切草锋利而节能和降噪；又由于采用带有多种而不是单个阻尼机构的绕线装置，多种互补更可靠，即由离心慢回缩装置，侧活塞阻尼装置，位置锁及球位置锁，逆阻机构，排管器角度槽式阻尼机构所互补的卷管器，从而大大增加了割草范围；或许可以说，其开创了一种有浇灌和施肥及洒药以及防撞对数螺线自动抱刹的割草机的新领域；而发明函数波盘改闷刹聚能为张弛抱刹，间歇脉动而散开能量的刹车新理念亦作为一种创举的刹车方法而用之于多种领域；有自动抱刹防护的对数螺线刹车器的割草机，因其刹车器制动杆的弧形有对数螺线的一段具有压力角处处相等的特性，形成实质的有凸轮结构的刹车器，已批量生产碍，解决了不容易使割草刀急停而符合安规的难题。卷管器的管内的液体肥料是水里加有可溶化的按百分比的农药或肥料易于更换。增加了浇灌和施肥及洒药的功能，使用范围广，活动区域大；卷管器的管内装有的用于施肥的液体肥料是水里加有可溶合的按百分比的肥料。或卷管器的管内装有的用于洒药的液体农药是水里加有可溶化的按百分比的农药。操作步行者拉动自走操纵手柄，通过钢丝绳及拨杆，使离合块沿轴向移动来接合。本技术的自走机构的后轮驱动齿轮减速离合器内的离合装置的 离合块，不但靠离合块侧面的圆锥来接合，而且有端面的波形来辅助接合。当操作步行者松开自走操纵手柄，通过钢丝绳及拨杆弹性复位，使离合块沿轴向移动来离开。由于端面是圆滑的正弦波形较之牙嵌离合块更易离开。设在割草机上的吹吸机(229)，其吹吸机(229)的集尘袋支架(35)连接有集尘袋(36)，且所述集尘袋(36)有管道与割草机后部的集草箱相接；所述吹吸机(229)设有喇叭形吹吸口(230)；在割草机底盘的割草刀上设吹吸风叶(231)以及设扫帚(232)直接吹吸扫。吹吸机和底盘的吹吸风叶及设扫帚都用时吹吸扫效果显著，都扫入割草机后部的集草箱的集尘袋里。
本发明涉及一种用于花坛、庭院、公园及道路旁边等场所吹吸树叶以及割草的工具，含一种吹吸机的改进，包含加装活动的辅助手柄，集尘袋支架及扎口的改进，机壳出尘口加柔和片，吹叶轮加刃口，电路加保险和双开关，及吹吸机内外加消声减振材料及蜂巢，滚轮改为可转向，以及把单伸出筒改为多伸出管或柔性折叠管，以及提高同轴度，测动平衡，及有激光照准工装的方法，以缩小体积，吹吸口用喇叭形，有利更广泛地吹吸，提高品质和安全性。
依据本发明的理想实施办法为启示，通过本说明书的内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。对相近领域的技术人员来说，显然还有许多等同技术的改动，但在不偏离权利要求实质内容的前提条件下，所做的改动仍属本专利的权利保护范围。
以下再就本发明解决其技术问题所采取的具体实施方式作详细解说：
因为一种低振动树叶吹吸机的改进，包含加装活动的辅助手柄，集尘袋支架及扎口的改进，即大身上壳出尘口加柔和片，吹叶轮加刃口，电路加保险和双开关，及吹吸机内外加消声减振的材料及蜂巢，滚轮改为可转向，以及把单伸出管改为多伸出管或柔性折叠管的多种综合改进，所以操作手感及效果均有改观。因为所述的改进的低振动树叶吹吸机，由自攻螺钉1，大身上壳2，电源线3，电缆护套4，开关扳机5，开关扳机弹簧6，端子台7，电缆压板8，电容9，自攻螺钉10，主开关11，调速器12，橡胶垫片13，电机14，风叶垫片15，吹叶轮16，六角螺母17，风叶塞片18，自攻螺钉19，转动轴盖20，弹簧21，挡圈22，吹吸转换板23，大身底壳24，安全开关25，转动轴26，吹吸转换旋扭27，侧按钮28，扭簧29，扭簧轴30，伸缩管31，轴用挡圈32，轮子33，轮轴34，集尘袋支架35，集尘袋36，六角头螺栓37，方型辅助手柄旋钮38，自攻螺钉39，辅助手把盖40，辅助手把底41，M6螺母42，背带43，以及尼龙扎带44，弹性碰珠自动定位器45，或多伸出管46，或柔性折叠管47，吹出的多伸出管48所组成；所述的自攻螺钉1是多个，其固定所述的大身上壳2和大身底壳24；其装配方法时，打自攻螺丝要用定扭矩的气动螺丝批或电动螺丝批，以使扭矩合理均匀；又因为所述的大身上壳2和大身底壳24是一左一右装合的，其含手柄部位，辅助手柄部位，伸出管限位器部位，马达蜗壳部位，吹吸换门部位，出尘口部位，及几个外挂部位；在所述的一左一右装合的大身上壳2和大身底壳24的手柄部位上，依此装入所述的电源线3，电缆护套4，开关扳机5，开关扳机弹簧6，端子台7，电缆压板8，电容9，自攻螺钉10，主开关11，调速器12；在所述的一左一右装合的大身上壳2和大身底壳24的马达蜗壳部位上，依此装入所述的橡胶垫片13，电机14，风叶垫片15，吹叶轮16，六角螺母17，风叶塞片18；在所述的一左一右装合的大身上壳2和大身底壳24的 吹吸换门部位，依此装入所述的自攻螺钉19，转动轴盖20，弹簧21，挡圈22，吹吸转换板23，大身底壳24，安全开关25，转动轴26，吹吸转换旋扭27；在所述的一左一右装合的大身上壳2和大身底壳24的伸出管限位器部位，依此装入所述的侧按钮28，扭簧29，扭簧轴30及伸缩管31；所述的伸缩管31含圆筒和方管并在前部互联，且在前下部设有安轮部位；在所述的伸缩管31的前下部设有的安轮部位，依此装入所述的轴用挡圈32，轮子33，轮轴34；在所述的一左一右装合的大身上壳2和大身底壳24的出尘口部位，设有柔和片2a；所述的柔和片至少一片，或多片，例如三片，如图4，图5及图11所示；所述的柔和片通常设在上壳，视机型不同，或在两壳都设之；所述的柔和片通常直接注塑在壳上，其呈三角形或斜四边形或梯形；或者，所述的柔和片不直接注塑在壳上，则用柔性材料，例如纤维织物，所以吹出杂物入袋时不至于太猛，袋口也不易掉；又因为在所述的一左一右装合的大身上壳(2)和大身底壳(24)的出尘口部位的外面设有两个卡槽，故便于卡挂集尘袋支架35和集尘袋36；又因为所述的集尘袋支架35，设有挂钩35a，挂钩筋35b，挂钩侧隙35c，及大套袋圈35d和小套袋圈35e；原有的挂钩筋35b，只有2个，撑力较差，致使挂钩35a有偶尔松脱；现改为挂钩筋35b，有3个或更多，撑力较高，使得挂钩35a不易松脱；所述的集尘袋(36)由纤维织物制作，设有拉练和两个连带挂扣，便于使挂扣挂在所述的壳上的外挂部位的挂钩上；而拉练是为拉开袋去倒出碎树叶用的；又因为采用了一种集尘袋支架扎袋口的改进方法：即首先准备好市售的有倒钩扣的尼龙扎带44，放在集尘袋36的纤维织物内，包之再用缝纫机制成缝线36，然后打开拉练，把制备好的集尘袋36的纤维织物的缝线36包住边的扎带44放入所述的集尘袋支架35的大套袋圈35d和小套袋圈35e之间，从拉练的大开口处，伸进钳子，拉紧有倒钩扣的尼龙扎带44，并剪去太长的带就成了，又易制作，袋又牢靠；又因为在所述的一左一右装合的大身上壳2和大身底壳24的辅助手柄部位，依此装入所述的六角头螺栓37，方型辅助手柄旋钮38，自攻螺钉39，辅助手把盖40，辅助手把底41，M6螺母42，组成了可活动辅助手柄；所述的辅助手柄的辅助手把盖40上，参看图6，图7和图10，设有呈弧形的连通柄40a，故便于保护手背，还设有端部的多个放射齿楞40b，亦有利卡位。原有的另一款式的吹吸机壳上的辅助手把2b，如图11所示，是固定的，不如所述的辅助手把盖40顺手好抓。
因为采用本发明提供的一种低振动树叶吹吸机的改进的加有保险防护的安全电路，故更安全。所述的一种低振动树叶吹吸机的改进，其含加有保险防护的安全电路，参看如图25所示的电路示意图，由端子台7，保险RC，双刀开关K，电感L，电容C，及设有绕组的串激电机M，以及调速器12所组成；所述的调速器12由双向可控硅TC和双向可控硅DC，电阻R1，电阻R2，可变电阻R3，电容C2及调速开关K3所组成；本发明特意加有双刀开关K和保险RC，其用保险丝，或用热继电器，或用过流保护器，以求更安全；为什么电源内已有保险，还要加保险？因为供电源还供多处，其保险往往太大，并不刚好适合本款树叶吹吸机；所述的可变电阻R3和调速开关K3实质上是电位器，当将其旋转时，可使双向可控硅的导通角变化，使电机转速可调，转至端点使调速开关闭合时，则是全速。
因为采用所述的一种低振动树叶吹吸机的改进，特别是按照不同机型采用不同搭配的材料，其含吹吸机内外及在吹吸机的多处加减震消声材料和蜂巢结构的减振动方案，是 本发明的重大贡献，故此减震消声方案还可用于其它多类如打草机及吸尘器。因在马达外加减振动的泡沫塑料，并在吹吸机的多处加减震消声材料，以及在吹和吸的风道多处设置蜂巢结构，其示意如图4的减振消声处43所示；在机壳内外，及各伸缩管内外，设多处减振消声蜂巢结构，其呈许多个密集互联的六角形并含消声尖劈结构，其密度及其宽深比，与吹吸机的振动参数和噪音特性有关，要多次测试；在机壳内外，及各伸缩管内外和马达外，加装的减震消声材料，或用金属纤维，或非金属材料，填充或半填充；或用耐中温的吸音材料特别是多孔吸声材料，或柔性材料，及膜状材料；所述的多孔材料可为纤维类，泡沫类，颗粒类，单用也行，或多或少混合应用也行；可用纤维类如岩棉，或玻璃丝，或玻璃棉特别是超细玻璃棉；或用泡沫类，在靠温升高处如马达处，要防火的；或用颗粒类如膨胀珍珠岩，多孔陶土砖，及耐温的织物，毡来填充，或贴附；所述的蜂巢结构也可预制后贴附，或混合模压。由于各材料的吸声系数(驻波管法吸声系数，混响法吸声系数)不同，入射角度对吸声系数亦有影响，有的对高频声吸收较好，有的对低频声吸收较好，多种材料有互补的效能，振动波及噪音被反射，转化，吸收，衰减，故有利于进一步改良性能指标。
原有吹吸机产品的附件仅有背带43，是挂在壳上和背在操作者肩上的；本发明建议，改进的低振动树叶吹吸机，在其附件内加设口罩，手套及防护眼镜和保险；吹吸机设在有四轮的割草机上，就是用轮和推车，故既提升了产品档次，又方便了用户，能用背带43远程来微调和驾驭吹吸机的吹吸方位。
因为一种低振动树叶吹吸机的改进，其含吹叶轮加刃口的改进，即在所述的吹叶轮加设有刃口，如图8，及放大的刃口如图18所示，含顶部刃口16a及侧周刃口16b，所述的顶部刃口16a的吹叶轮叶片顶面与吹叶轮叶片正面的夹角为锐角；而所述的侧周刃口16b的吹叶轮叶片侧周面与吹叶轮叶片正面的夹角亦为锐角；所述的吹叶轮加设的刃口或是沿叶片正面的边缘局部较短，或是沿边缘大部较长；其刃口是直刃或是弧形刃，或是多折刃，且其弧形刃是阿基米德线，或抛物线。作为改进，在所述的吹叶轮还或可另加设有刃钢刀，例如用条形刀；作为改进，在所述的吹叶轮叶片上，还可设含多个椭圆形及六角形的降噪孔，这均有利碎片及吹吸。
因为把接触地面的滚轮改为可转向，成为易转向吹吸机，不但增加了吹吸机的另一花色品种，而且满足了有些操作步行者喜欢和习惯用吹吸机时，特别是遇到边角地方时，左顾右盼和转过角度来吹吸以方便工作的要求。又因为把原有的伸缩管31头部下方的轮轴架分拆开，使之成为一个独立的零件轮轴架31a，在原有的伸缩管31头部下方安放轮轴架的地方设一个孔，以插入所述的轮轴架31a上的环卡槽的立轴，如图23的爆炸图所示；其余和原来一样，仍是在轮轴架31a中穿轮轴34，再安上一对轮子33，各装上轴用挡圈32，所以也较方便。
因为采用了改进，即如图20及图22所示，把单伸出筒改为多伸出管46，并设自动定位器，例如弹性碰珠自动定位器45，或碰块的自动定位器，或扭簧的自动定位器，而不用 人再用手去按按键，故缩小了体积，可随意拉缩到位既自动定位，提高了工效，降低了运输成本。所述的与自动定位器相配的多伸出管46是多节，例如4节；多伸出管46均设有凹槽与定位器适配。联想到了可自由拉进拉出的拉杆天线的原理，把它改进并用到吹吸机作多伸出管46，如图24所示，不妨把小的吸管称为多伸出管48；所述的多伸出管46和多伸出管48的特征均是一端内翻边，而另一端外翻边；且其鱼贯地一节接一节，是多节，最少4节，故拉出或回位自如，因均在其翻边处有凸凹卡位。因吹吸机的管长按标准如IEC60335-2-100，或按标准如BSEN15503：2009，均仅为0.9米，故拉杆长度是能实施的。不但联想到了可自由拉进拉出的手风琴的原理，以及常用的吸尘器和洗衣机的可叠软管，而且把它改进并用到吹吸机作多伸出管，如图21所示，不妨把管称为柔性折叠管47；为方便定位，或与多伸出管(48)并用；所述的柔性折叠管47的特征是：其有多个折叠，无论其截面是方的或是圆的或是其它形状，其管的相邻的环周是一大圈一小圈地相间排列的即鱼贯地一粗节接一细节的，其节是多节，最少4节或更多；或者，所述的柔性折叠管47的管材用柔性材料如织物，布，塑膜，同时沿柔性管间隔设有多个环圈，或沿柔性管，套装螺旋弹簧作为间隔环圈，以便支撑和拉进拉出；该螺旋弹簧是稀疏的和柔性的，故可大幅收回。
又因为采用了本发明对一种低振动树叶吹吸机的改进的又一项重要提供，即为提高制造及装配精准度的含激光的方法，系提高马达和吹叶轮同轴度及测动平衡的既有精密模制部件又有激光照准工装的改进方法，故产品质量有提高。因吹吸机的振动和噪音的很大根源在动力和工具的精度与形位公差，所以要提高马达和吹叶轮同轴度，并要测动平衡，以求对吹吸机的低振动低噪音这项长期遗留的老大难问题有一定疗效；首先，从图纸设计上提高了对形位公差的要求，例如对马达和吹叶轮总成同轴度和形位公差的要求，还加大了马达和吹叶轮过盈量，再用加力工装夹具压合；再则，用数控CNC加工中心制备精密模具，并对塑件如吹叶轮进行后处理，其主要方法是用高温蒸气法，最好是蒸够三小时以上，故塑件尺寸不易变形走样；其次，为提高马达和吹叶轮同轴度，装配时，采用专用的校准马达和吹叶轮总成同轴度的有激光照准的工装压机，压合后，并经批量抽样测动平衡修正才上产线，且最后整机也抽样测动平衡，故再辅以多处减震消声材料，就综合组成了一种有改进的且减振，安全，好用的高档次的低振动树叶吹吸机。
有底盘叶片扫帚的吹吸及浇灌和施肥洒药及抱刹的割草机，其是含设有防撞保险对数螺线刹车器和设有浇灌和施肥及洒药的液体管线的卷管器的多功能的割草机；是在普通草坪割草机上加设有四大总成，系设有充电器和逆变器的蓄电池的支架总成，设有串激电机所拖动的切割装置总成，及设有浇灌和施肥及洒药的卷管器总成，以及设有刹车器总成和切割装置总成；增加了浇灌和施肥及洒药的功能，使用范围广，活动区域大；卷管器的管内装有的用于施肥的液体肥料是水里加有可溶合的按百分比的肥料或农药。设在割草机上的吹吸机的集尘袋支架(35)连接有集尘袋(36)且有管道与割草机后部的集草箱相接。在割草机底盘的割草刀上设吹吸风叶(231)以及设扫帚(232)直接吹吸扫。
本发明涉及一种用于庭院、公园及道路旁边等场所修剪草坪的草坪割草机，是改进的具自动充电销插入及拔出接触片组件的智能割草机；是在其含设在割草机底盘前部的防撞保险器以及含设有防撞保险能自停的对数螺线刹车器及设有低振动树叶吹吸机及含加装集尘袋支架及扎口及大身上壳出尘口加柔和片，吹叶轮加刃口，电路加保险和双开关，及吹吸机内外加消声减振的材料及蜂巢，滚轮改为可转向，以及把单伸出筒改为多伸出管或柔性折叠管，综合设吹吸及打草头及设有浇灌和施肥及洒药的液体管线的卷管器的多功能的割草机的基础上，再设改进的具自动充电销插入及拔出接触片组件的智能割草机，以便可靠地自动插拔充电；恰似汽车需要加油站一样，电动割草机也需要充电站，市场需要一种具自动充电销插入及拔出接触片的充电组件的智能割草机，以便可靠地自动插拔充电；于是一种改进的具自动充电销插入及拔出接触片组件的智能割草机就应运而生了，解决了电池不耐用需频繁人工充电的问题；改进的具自动充电销插入及拔出接触片组件的智能割草机，其特征在于，其含改进的具自动充电销插入及拔出接触片组件；所述的具自动充电销插入及拔出接触片组件，其含具自动充电销插入部件的固定的供电部件，还含割草机机身的具拔出接触片的活动的受电部件；所述具自动充电销插入部件的固定的供电部件，设有水平铺于地表的底板、立于前方的前墙、供电源、地脚螺钉，所述水平铺于地表的底板的左侧及右侧各设有沿中轴线对称的导向轨(233c)，以便对割草机的前部的机身的沿中轴线对称的左侧及右侧予以导向；且所述水平铺于地表的底板的左侧及右侧各所设有的沿中轴线对称的导向轨(233c)的每个导向轨的曲线段是立方曲线，以便减缓冲击；所述水平铺于地表的底板的四脚设有所述地脚螺钉，以便固定；所述水平铺于地表的底板的前部设有所述的立于前方的前墙；所述的立于前方的前墙上设有沿中轴线对称的左侧及右侧各一的所述的充电销((233)，所述的充电销((233)的根部设有销球(233a)，以便微量随动，所述的充电销((233)的根部设有螺纹，以便与所述供电源相连；所述的充电销((233)的头部设有插入面(233b)，以便充电销插入及拔出接触片；所述水平铺于地表的底板沿中轴线铺设和引出并在工作区域沿地表铺设有电磁脉冲的引路导线，以便通过割草机前部下方的传感器(234d)并通过电路板智能引导割草机要充电时行走到所述具自动充电销插入部件的固定的供电部件的设有水平铺于地表的底板上；所述含具拔出接触片的活动的受电部件设在割草机前部，所述含具拔出接触片的活动的受电部件含所述的割草机前部下方的传感器(234d)和设在割草机前部的接触片(234)及压片扭簧(234a)以及转轴；所述接触片(234)及压片扭簧(234a)以及转轴各共有四个，每一个所述接触片(234)及压片扭簧(234a)以及转轴组成一个活动门，而所述每一个所述接触片(234)及压片扭簧(234a)以及转轴组成的一个活动门与所述每一个所述接触片(234)及压片扭簧(234a)以及转轴组成的另一个活动门形成面对面的对开的双门，左侧和右侧各有所述的双门的活动门的面对面的每个所述的接触片(234)的接触面((234b)对应所述的立于前方的前墙上所设有的沿中轴线对称的左侧及右侧各一的所述的充电销((233)的头部所设有的所述的插入面(233b)，由充电销靠销球(233a)微量随动插入；当充至设定值时会启动割草机后退，使充电销拔出接触片，继而工作；当又要充电时割草机行走到所述具自动充电销插入部件的固定的供电部件的水平铺于地表的底板上并由充电销插入。
