Description

一种大型农场灌溉渠用船式喷灌机 技术领域
本发明涉及一种喷灌机，具体是一种适用于具有灌溉渠的大型农场的、针对农田进行喷灌作业的船式喷灌机，属于喷灌设备装备技术领域。
背景技术
喷灌是利用喷头等专用设备把有压水喷洒到空中，形成水滴落到地喷灌面和农作物表面的灌溉方法，喷灌机又称喷灌机具、喷灌机组，即喷灌所采用的专用设备。
为了便于取水进行灌溉和喷灌，大型农场通常在农田之间设置灌溉渠。由于卷盘喷灌机能够灌溉大面积的农田，也可以根据喷头控制喷水量的大小以满足使用者对喷灌水量的不同要求，因此大型农场通常采用卷盘喷灌机进行农作物喷灌作业。具有灌溉渠的大型农场进行喷灌作业时通常是将卷盘喷灌机停滞在靠近灌溉渠的田间地头，然后通过抽水泵供应压力水，利用拖拉机或绞车等牵引设备把连接在PE管上的喷头车拖出至预设的喷灌地点，然后再开启抽水泵，喷灌压力水进入PE输水管自喷头车的喷头喷出进行喷灌作业的同时带动绞盘回转实现PE管的自动回收。
这种具有灌溉渠的大型农场的传统卷盘喷灌机喷灌方式存在以下缺陷：
1、由于卷盘式喷灌机通常是通过拖拉机等牵引设备牵引至需喷灌的农田地头，而通常农田地头往往因为保证尽量大的种植面积而空间有限，因此造成卷盘式喷灌机整机转向调头较困难，当喷灌作业完成后进行转场时往往会造成田间地头的农农作物被过分碾压的情况；
2、传统的卷盘式喷灌机因卷盘的设置造成宽度尺寸较大，而为了保证喷头车的直线行走，通常喷头车的宽度尺寸与卷盘的宽度尺寸配合，因此针对低矮农作物进行喷灌作业时为了防止碾压农作物、通常将喷头车的轮间距与农田的垄间距尺寸配合，且PE管在地面拖行过程中也会对农作物造成挤压损伤；而针对玉米、高粱等高度较高的农作物若进行喷灌作业，则通常需在种植时就在农田里预留供喷头车行走的通道，进而造成种植面积的减少；
3、由于喷灌作业的覆盖区域通常是以喷头为对称中心呈扇面结构，因此针对平行于灌溉渠走向设置的农田，通常需要较长的输水管路。
发明内容
针对上述问题，本发明提供一种大型农场灌溉渠用船式喷灌机，能够在实现喷灌作业的同时完全避免对农田农作物的碾压，特别适用于具有灌溉渠的大型农场对农作物进行喷灌作业。

与现有技术相比，本大型农场灌溉渠用船式喷灌机由于在船体上设有喷灌辅助支撑机构，喷灌辅助支撑机构包括沿船体左右对称设置的支撑腿和安装在支撑腿底端的支撑滚轮组，因此将本大型农场灌溉渠用船式喷灌机置入大型农场的灌溉渠内使用时，支撑滚轮组通过支撑腿自船体的左右方向架设在灌溉渠的斜堤表面上、且螺旋桨没于灌溉水面之下，喷灌控制回路和船体移动控制回路开始工作后，灌溉渠内的灌溉水经吸水管进入自吸泵、被自吸泵增压后经喷头枪喷出，同时螺旋桨旋转推动船体移动实现对农作物的喷灌，喷灌辅助支撑机构不仅可以平衡喷头枪的后坐力、防止船体倾翻，而且可以提供船体的移动导向、保证船体始终沿灌溉渠的走向方向移动；由于支撑腿的顶端铰接安装在船体上、且支撑腿与船体之间设有伸缩升降控制部件，因此可以实现在左右方向上调节支撑腿之间的间距尺寸，进而实现适应不同的灌溉渠宽度尺寸；由于支撑滚轮组还包括支撑滚轮驱动，因此可以实现支撑滚轮的旋转、由被动旋转转变为主动旋转，进而实现支撑滚轮在船体行进过程中提供辅助推动力，在配合伸缩升降控制部件的升降操作的前提下可以实现本大型农场灌溉渠用船式喷灌机在地面上行走，通过在灌溉渠上设置合适的坡面进而可以实现本大型农场灌溉渠用船式喷灌机的自行下水和上岸，能够在实现喷灌作业的同时完全避免对农田农作物的碾压，特别适用于具有灌溉渠的大型农场对农作物进行喷灌作业。

所述的驱动动力源是固定安装在船体1上的发动机系统、或动力电源系统、或其他动力系统；以发动机系统为例，发动机系统包括发动机和变速箱，发动机的动力输出轴与变速箱的动力输入轴连接；以动力电源系统为例，动力电源系统包括动力电池组、推进动力电机和喷灌动力电机，动力电池组分别与推进动力电机和喷灌动力电机电连接。
所述的行进推进装置包括设置在船体1底部的螺旋桨，螺旋桨通过传动机构与发动机系统的变速箱动力输出轴连接、或者与动力电源系统的推进动力电机连接，行进推进装置提供船体1的移动推进动力。
所述的喷灌装置2包括自吸泵21、喷头架22和喷头枪23；自吸泵21固定安装在船体1上，自吸泵21的动力输入端通过传动机构与发动机系统的变速箱动力输出轴连接、或者与动力电源系统的喷灌动力电机连接，自吸泵21的吸水端口与没入灌溉渠液面以下的吸水管连接，自吸泵21的排水端口通过管路与喷头枪23连接；喷头架22对应支撑腿11的对称中心位置固定安装在船体1上，喷头枪23通过喷头枪调节组件固定安装在喷头架22上，通过喷头枪调节组件包括可以实现喷头枪23回转定位动作的喷射角度调节机构和喷射方向调节机构，喷射角度调节机构和喷射方向调节机构均可以采用如回转电机通过齿轮带动齿圈旋转的方式实现回转、或者采用如回转液压马达通过齿轮带动齿圈旋转的方式实现回转、或者采用其他的回转驱动方式，喷射角度调节机构可以调节并定位喷头枪23的喷射轴线与水平面之间的夹角，喷射方向调节机构可以调节并定位喷头枪23围绕竖直方向设置的旋转中轴线旋转的角度。

将本大型农场灌溉渠用船式喷灌机置入大型农场的灌溉渠内使用时，如图2所示，喷灌辅助支撑机构的支撑滚轮组12通过支撑腿11自船体1的左右方向架设在灌溉渠的斜堤表面上、且螺旋桨没于灌溉水面之下，调整好喷头枪23的喷射角度和喷射方向，然后通过电控装置3的控制器控制喷灌控制回路开始工作，控制器控制驱动动力源通过传动机构带 动自吸泵21工作，灌溉渠内的灌溉水经吸水管进入自吸泵21、被自吸泵21增压后经喷头枪23喷出实现对灌溉渠两边的农田农作物的喷灌；同时，通过电控装置3的控制器控制船体移动控制回路开始工作，控制器控制驱动动力源通过传动机构带动螺旋桨旋转工作，船体1即在螺旋桨的推进作用下移动，船体1移动过程中支撑滚轮组12跟随船体1在灌溉渠的斜堤表面上滚动移动。喷灌作业过程中喷灌辅助支撑机构不仅可以提供喷灌辅助支撑、平衡喷头枪23的后坐力，而且可以提供船体1的移动导向、保证船体1始终沿灌溉渠的走向方向移动。
为了能够根据不同的灌溉渠宽度尺寸实现本大型农场灌溉渠用船式喷灌机的通用性，作为本发明的进一步改进方案，支撑腿11是伸缩结构，支撑腿11包括本体段、伸缩段和支撑腿伸缩控制部件，本体段的顶端安装在船体1上，伸缩段与本体段滑动配合连接，支撑腿伸缩控制部件沿支撑腿11长度方向设置，支撑腿伸缩控制部件的一端与本体段连接、另一端与伸缩段连接，支撑腿11与船体1之间还设有伸缩升降控制部件13，伸缩升降控制部件13的两端分别与船体1和支撑腿11的本体段铰接连接；所述的电控装置3还包括支撑腿升降控制回路和支撑腿伸缩控制回路，控制器分别与支撑腿伸缩控制部件和伸缩升降控制部件13电连接。通过控制伸缩升降控制部件13和支撑腿伸缩控制部件的伸缩可以实现调节支撑腿11的摆动角度和长度，进而实现适应不同的灌溉渠宽度尺寸。
所述的伸缩升降控制部件13和支撑腿伸缩控制部件可以采用电动螺旋杆的电传动方式，也可以采用液压油缸结构的液压传动方式，由于电传动方式不仅需额外考虑与水的绝缘问题、而且负载较大的情况下电机易烧毁，而液压传动的方式不仅可以实现稳定支撑、而且可以避免上述问题，因此优选后者，即，作为本发明的优选方案，所述的伸缩升降控制部件13和支撑腿伸缩控制部件均是液压缸结构，大型农场灌溉渠用船式喷灌机还包括设置在船体1上的液压控制装置，液压控制装置包括液压泵站和液压控制阀组，液压泵站包括液压泵和液压油箱，所述的动力电源系统还包括液压泵站动力电机，液压泵站的液压泵通过传动机构与发动机系统的变速箱动力输出轴连接、或者与动力电源系统的液压泵站动力电机连接，液压泵站通过液压管路与液压控制阀组连接，液压控制阀组通过液压管路分别与液压缸连接，液压控制阀组与所述的电控装置3的控制器电连接，即液压缸通过液压控制阀组与所述的电控装置3的控制器电连接。
由于水的粘滞力作用，物体在水中的运行速度较低，且在相同推进力的前提下外界的风力、灌溉渠内的水流方向均会影响船体1的行进速度，为了实现较高的移动速度，作为 本发明的进一步改进方案，所述的支撑滚轮组12还包括支撑滚轮驱动，支撑滚轮驱动的输出端与支撑滚轮同轴固定连接；所述的电控装置3还包括支撑滚轮驱动控制回路，控制器与支撑滚轮驱动电连接。通过控制支撑滚轮驱动的旋转动作可以实现支撑滚轮的旋转、由被动旋转转变为主动旋转，进而实现支撑滚轮在船体1行进过程中提供辅助推动力。配合伸缩升降控制部件13的控制支撑腿11升降操作，可以实现支撑滚轮组12支撑于地面、螺旋桨悬空在支撑滚轮组12上方的状态，此状态控制支撑滚轮驱动旋转动作时可以实现本大型农场灌溉渠用船式喷灌机在地面上行走，通过在灌溉渠上设置合适的坡面可以实现本大型农场灌溉渠用船式喷灌机的自行下水和上岸。
所述的支撑滚轮驱动可以采用电机控制的电传动方式，也可以采用液压马达控制的液压传动方式，由于电传动方式不仅需额外考虑与水的绝缘问题、而且负载较大的情况下电机易烧毁，而液压传动的方式不仅可以实现稳定传动、而且可以避免上述问题，因此优选后者，即，作为本发明的优选方案，所述的支撑滚轮驱动是滚轮液压马达，大型农场灌溉渠用船式喷灌机还包括设置在船体1上的液压控制装置，液压控制装置包括液压泵站和液压控制阀组，液压泵站包括液压泵和液压油箱，所述的动力电源系统还包括液压泵站动力电机，液压泵站的液压泵通过传动机构与发动机系统的变速箱动力输出轴连接、或者与动力电源系统的液压泵站动力电机连接，液压泵站通过液压管路与液压控制阀组连接，液压控制阀组通过液压管路与滚轮液压马达连接，液压控制阀组与所述的电控装置3的控制器电连接，即滚轮液压马达通过液压控制阀组与所述的电控装置3的控制器电连接。
本大型农场灌溉渠用船式喷灌机可以采用人工操作方式，也可以采用自动操作方式，为了实现自动化智能喷灌作业，作为本发明的进一步改进方案，所述的电控装置3还包括船载工业控制计算机、船体位置反馈传感器、喷头枪喷射角度控制回路、喷头枪喷射方向控制回路，船载工业控制计算机通过数据线与控制器电连接，船载工业控制计算机包括喷灌数据输入输出端口，控制器分别与喷头枪调节组件的喷射角度调节机构和喷射方向调节机构电连接，船体位置反馈传感器设置在船体1的前后两端，船体位置反馈传感器与控制器电连接。操作人员通过喷灌数据输入输出端口将喷灌数据输入船载工业控制计算机，船载工业控制计算机根据具体的喷灌角度和喷灌方向发出指令使控制器控制喷射角度调节机构和喷射方向调节机构动作将喷头枪23定位在正确的喷灌角度和喷灌方向上，然后船载工业控制计算机根据具体的喷灌距离和降水量发出指令使控制器控制船体移动控制回路和喷灌控制回路开始工作，螺旋桨根据设定旋转速度工作，自吸泵21根据设定流量工作；当船体位置反馈传感器反馈船体1运行至设定喷灌距离时，船载工业控制计算机发出指令使控 制器控制船体移动控制回路和喷灌控制回路停止工作，即完成喷灌作业。
为了进一步保证船体1移动和喷灌作业的稳定性，作为本发明的进一步改进方案，如图3所示，所述的支撑腿11至少设置为四件，四件支撑腿11相对于船体1中心对称设置，且靠近船头位置的两件支撑腿11向前方倾斜伸出设置、靠近船尾位置的两件支撑腿11向后方倾斜伸出设置。前后方向倾斜伸出设置的四件支撑腿11可增加船体1移动和喷灌作业的稳定性。
为了防止因灌溉渠的斜堤表面不平造成喷灌辅助支撑机构的卡死状况、进而造成船体1无法移动，作为本发明的进一步改进方案，支撑腿11的底端与支撑滚轮组12之间还设有具有导向滑移机构的阻尼压簧，阻尼压簧的一端安装在支撑腿11上、另一端安装在支撑滚轮组12上。阻尼压簧可以实现支撑腿11根据灌溉渠的斜堤表面进行自适应控制，进而防止因灌溉渠的斜堤表面不平造成喷灌辅助支撑机构的卡死状况。
为了实现更稳固的辅助支撑效果，所述的支撑滚轮组12可以是前后或左右设置的多个支撑滚轮结构，也可以是履带轮结构，由于后者的支撑面积更大、可以实现更好的支撑效果，因此优选后者，即，作为本发明的优选方案，所述的支撑滚轮组12是履带轮结构，履带轮结构包括履带梁和履带，履带梁与支撑腿11安装连接，所述的支撑滚轮是铰接安装在履带梁上的多个履带轮，履带首尾连接呈环状套接安装在履带轮上。
为了避免因电池电量问题影响控制器的控制，作为本发明的进一步改进方案，所述的电控装置3还包括太阳能集电板和太阳能充电控制回路，太阳能集电板分别与控制器和控制器电池组电连接。
本大型农场灌溉渠用船式喷灌机由于在船体1上设有喷灌辅助支撑机构，喷灌辅助支撑机构包括沿船体1左右对称设置的支撑腿11和安装在支撑腿11底端的支撑滚轮组12，因此将本大型农场灌溉渠用船式喷灌机置入大型农场的灌溉渠内使用时，支撑滚轮组12通过支撑腿11自船体1的左右方向架设在灌溉渠的斜堤表面上、且螺旋桨没于灌溉水面之下，喷灌控制回路和船体移动控制回路开始工作后，灌溉渠内的灌溉水经吸水管进入自吸泵21、被自吸泵21增压后经喷头枪23喷出，同时螺旋桨旋转推动船体1移动实现对农作物的喷灌，喷灌辅助支撑机构不仅可以平衡喷头枪23的后坐力、防止船体1倾翻，而且可以提供船体1的移动导向、保证船体1始终沿灌溉渠的走向方向移动；由于支撑腿11的顶端铰接安装在船体1上、且支撑腿11与船体1之间设有伸缩升降控制部件13，因此可以实现在左右方向上调节支撑腿11之间的间距尺寸，进而实现适应不同的灌溉渠宽度尺寸；由于支撑 滚轮组12还包括支撑滚轮驱动，因此可以实现支撑滚轮的旋转、由被动旋转转变为主动旋转，进而实现支撑滚轮在船体1行进过程中提供辅助推动力，在配合伸缩升降控制部件13的升降操作的前提下可以实现本大型农场灌溉渠用船式喷灌机在地面上行走，通过在灌溉渠上设置合适的坡面进而可以实现本大型农场灌溉渠用船式喷灌机的自行下水和上岸，能够在实现喷灌作业的同时完全避免对农田农作物的碾压，特别适用于具有灌溉渠的大型农场对农作物进行喷灌作业。
