Description
本发明涉及一种用于电动驾乘式草坪修剪机的工作附件，尤指一种用于电动驾乘式草坪修剪机的中排后集草刀盘。
在草坪养护领域，尤其是公园、高尔夫球场、运动场等大面积草坪区域，电动驾乘式草坪修剪机因其工作效率高而被广泛使用。传统的电动驾乘式草坪修剪机的工作附件，即刀盘，大多是两刀或三刀形式，且一般采取纯侧排草方式，或者采取侧排草再通过输送管道送至后部的集草箱内收集。从实际使用效果来看，已有的侧排草方式都存在草坪修剪机尺寸较大、占据空间大，结构复杂，草屑收集效果不佳的问题。目前市场上还出现了中排后集草的方式，此方式所使用的中排后集草刀盘在为了保证随草坪修剪机行进中不发生漏草的现象，必须相对于草坪修剪机前进方向斜置，或者使用同步带来传动。但是，中排后集草刀盘斜置带来的直接问题就是会导致草坪修剪机的长度增加，整个结构不够紧凑，而同步带传动方式则存在传动可靠性不佳的问题。
由此可见，设计出一种结构紧凑、运行可靠、草屑收集效果好的中排后集草刀盘，是目前急需解决的问题。
发明内容
本发明的目的在于提供一种电动驾乘式草坪修剪机的中排后集草刀盘，其结构紧凑，在与集草箱配合下可实现中排草、后集草功能，提升了草屑收集效果，适于推广。
为了实现上述目的，本发明采用了以下技术方案：
一种电动驾乘式草坪修剪机的中排后集草刀盘，其特征在于：它包括安装在机架下方的刀盘壳，刀盘壳上安装有多个主刀电机，主刀电机上安装有主刀片，刀盘壳内对应于每个主刀片的旋转中心为一上旋圆弧形风道，风道出口连接有排草挡板或集草导管，集草导管用于连接机架后部的集草箱；所有主刀电机排列在与修剪机前进方向垂直的同一条直线上；在刀盘壳上，每相邻的两个主刀电机的前方安装有一副刀电机，副刀电机上安装有副刀片，副刀片处于风道外；主刀片的旋转方向与风道上旋方向一致，以使主刀片将修剪下的草屑沿风道推送至排草挡板或集草导管；副刀片旋转方向任意。
本发明的优点是：
本发明结构紧凑，有效压缩了电动驾乘式草坪修剪机的长度，在与集草箱 配合使用下可实现中排草、后集草的目的，且大大提升了草屑收集效果，运行可靠，工作效率高，可广泛适用于公园、运动场、高尔夫球场等需大面积草坪养护的场所。

如图5，零转弯机型草坪修剪机包括机架20，机架20的前部下方安装有万向轮作为前轮30，机架20的中部下方安装有本发明中排后集草刀盘10，本发明中排后集草刀盘10的集草导管16从两个后轮50之间穿过并与机架20后部安装的集草箱60连通(本发明中排后集草刀盘10也可直接安装排草挡板17而不与集草箱60连通)，机架20上安装有行走机构70和控制器，控制器与本发明中排后集草刀盘10的主刀电机12、副刀电机13电连接，用于对修剪作业的启动与停止进行控制。行走机构70包括轮毂无刷电机和操作手柄，机架20每侧安装一轮毂无刷电机和一操作手柄，各轮毂无刷电机通过固定轴套安装在机架20上，各轮毂无刷电机上套装有后轮50，各操作手柄的底部安装有角度传感器，机架20同侧的角度传感器、轮毂无刷电机与同一行走控制器电连接。控制器、行走控制器分别与修剪启动按钮、行走启动按钮电连接。当按下修剪启动按钮后，各主刀电机12、各副刀电机13运行，开始修剪作业。当按下行走启动按钮、合拢两个操作手柄后，角度传感器开始检测操作手柄的摆动位置，即工作人员通过操纵两个操作手柄来控制零转弯机型草坪修剪机的行进状态。例如：令两个操作手柄处于中位，保持静止；令两个操作手柄偏离中位同时向前，则两个轮毂无刷电机带动后轮向前转动，呈现前进状态；令两个操作手柄偏离中位同时向后，则两个轮毂无刷电机带动后轮向后转动，呈现后退状态；令两个操作手柄偏离中位、一个向前一个向后，则两个轮毂无刷电机带动后轮呈现一个正转、一个倒转，从而实现零转弯动作。
如图6，方向盘机型草坪修剪机包括机架20，机架20的前部下方安装有前轮30，机架20的中部下方安装有本发明中排后集草刀盘10，本发明中排后 集草刀盘10的集草导管16从两个后轮50之间穿过并与机架20后部安装的集草箱60连通(本发明中排后集草刀盘10也可直接安装排草挡板17而不与集草箱60连通)，机架20上安装有行走机构70’和控制器，控制器与本发明中排后集草刀盘10的主刀电机12、副刀电机13电连接，用于对修剪作业的启动与停止进行控制。行走机构70’包括操作装置，操作装置通过驱动装置来控制后轮50的运行，从而实现停止、前进、后退与转弯。操作装置包括方向盘、控制前进与后退的操纵杆。控制器、驱动装置分别与修剪启动按钮、行走启动按钮连接。当按下修剪启动按钮后，各主刀电机12、各副刀电机13运行，开始修剪作业。当按下行走启动按钮后，驱动装置开始接收操作装置的指令，即工作人员通过操纵方向盘和操作杆来控制方向盘机型草坪修剪机的行进状态。
在本发明中，设定电动驾乘式草坪修剪机的车头为前，车尾为后。
本发明的优点是：
本发明结构紧凑，有效压缩了电动驾乘式草坪修剪机的长度，在与集草箱配合使用下可实现中排草、后集草的目的，且大大提升了草屑收集效果，运行可靠，工作效率高，可广泛适用于公园、运动场、高尔夫球场等需大面积草坪养护的场所。
以上所述是本发明较佳实施例及其所运用的技术原理，对于本领域的技术人员来说，在不背离本发明的精神和范围的情况下，任何基于本发明技术方案基础上的等效变换、简单替换等显而易见的改变，均属于本发明保护范围之内。
