Description

采摘机电池驱动装置
本申请要求申请日为2020年3月27日、申请号为202010229217.5的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及采摘机技术领域,例如涉及一种采摘机电池驱动装置。
背景技术
目前,在采集花蕾和茶果的时候大多采用的是人工采集,而且时间集中、时间短,需要大量的人力物力,采摘不及时容易造成茶果浪费。例如对于具有要药用价值花蕾的采集,都是采用人工来进行操作。人工采集操作存在着一些缺点:一是人工采集效率比较低下,一般一个人1小时采集花蕾量在1~2斤;二是人工采集需要人用手指进行采摘,采摘时间较长后,会造成腰酸手痛,容易疲乏。
其它大型机械式震荡采摘设备,通过震荡枝干枝条使果实脱落,同时进行果实的收集。这种采摘方式对果树本身损伤极大,且落果量多,所以实施性不强。另一种是小型采摘设备,通过负压或拨齿将果实吸入或卷入采摘设备中,使其与枝条脱离。负压吸入式采摘方式,气吸压力小不能使果实成功脱离枝条完成采摘,气吸压力大会导致果树和果实破损,同时会将树叶和树枝吸入,划破果实。拨齿卷入式采摘方式,由于设备的捕捉口不能进行调节,不便于设备对果实进行捕获,且拨齿的卷入力不可调节,容易损坏枝条和果实。
还有汽油机背负式采摘机,操作人员背负汽油机;手持采摘杆重量大,劳动强度大,例如,汽油机要通过软轴把动力输入到采摘机安全性差;而且在云南等高原区域气压低,汽油机不能正常工作,在新彊区域禁止使用汽油机。
发明内容
本申请提供了一种采摘机电池驱动装置,其结构简单、携带方便、运行稳定性好,使用效果佳。能够处理采摘费时费力的情况。提高采摘效率,同时降低劳动强度。
一实施例提供一种采摘机电池驱动装置,包括壳体,所述壳体内设有电池 腔、电机腔和手柄腔;
其中,所述电池腔内设置有至少一个电池,所述电机腔内设置有电机;所述电机的第一端设有传动轴,所述传动轴的第一端套设有传动套,所述传动套内设有与所述传动轴连接的轴承,所述电机的第二端设有与电池相连接的PCB电路板;
所述手柄腔内嵌接有与所述PCB电路板电连接的电源开关。

其中,R5色环电阻与保险丝间设有Q1场效应管。场效应晶体管简称场效应管。主要有两种类型:结型场效应管和金属-氧化物半导体场效应管。由多数载流子参与导电,也称为单极型晶体管,属于电压控制型半导体器件。

实施例:
如图1、图2和图3所示,一种采摘机电池驱动装置,包括壳体1,壳体1采用分体式结构,或采用整体式结构。壳体1内设有电池腔2、电机腔3和手柄腔4。电池腔2内套接有一个电池15,电池15为充电电池,或一次性电池。电池15尾端设有与壳体1螺纹连接的端盖16,端盖16与电池15间设有压簧17。电池15采用外置结构,PCB电路板13与电机腔隔板18间设有输出接口19。电机腔3内套接有电机9,电机9前端设有减速机8,减速器8采用行星减速器,或采用齿轮减速器。减速机8前端设有传动轴6,传动轴6设置为与采摘机构连接。减速机8与传动轴6之间采用联轴器式套接,或采用销连接,或采用螺纹连接。传动轴6的一端套设 有传动套5,传动套5固定于电机腔3内,且传动套5与电机腔3的内壁之间采用螺纹式夹紧。传动套5内设有与传动轴6连接的轴承7,电机9后端设有与电池15相连接的PCB电路板13,PCB电路板13与电池15间设有四个传电片14,电池腔2与电机腔3间设有电机腔隔板18,其中两个传电片14嵌接在电池腔2中,另外两个传电片14设置在电机腔隔板18上,四个传电片14设置为实现电池15和PCB电路板13之间的连接。PCB电路板13连接有启动开关12、保险丝10、电源开关11。启动开关12设置在手柄腔4中,保险丝10设在电机腔3中且位于电机9与PCB电路板13之间。手柄腔4内嵌接有与PCB电路板13相电路连通的电源开关11。
当电源开关11开启,启动开关12断开时,R1色环电阻、HL1红灯与电源开关11串联,启动开关12与R2色环电阻、HL2绿灯串联,此时HL1红灯亮,HL2绿灯不亮,电机9处电路呈断开状态。当同时将电源开关11与启动开关12开启,HL1红灯、HL2绿灯均亮起,电机9得电启动。Q1场效应管与R3色环电阻、R4色环电阻、R5色环电阻共同起到控制电机9的输出功率的作用。
综上所述,该采摘机电池驱动装置,具有结构简单、携带方便、运行稳定性好和使用效果佳的特点。解决了采摘费时费力的问题。提高采摘效率,同时降低劳动强度。
