Description

一种农用车 技术领域
本发明涉及一种农用车。
背景技术
农业自动化为现代化农业的标志，各种农机设备代替原始的人力劳动，使农业生产效率成倍增长。农机设备虽然需要具备一般机动车的性能，但是一般机动车不能满足农机设备的需求，这是因为农机设备所运行的环境大多在松软的泥土或者长满庄稼的田地，甚至是充满泥水的水田。农用车是一种专门用于水田农作业的农机设备，作业环境充满泥水及生长中的庄稼，现有高花车轮由于自身重量较重，轮面较宽，进行农田作业时，很容易压坏作物，能耗大，效率低，不适合环保能源。
另外，由于农田类型不同，或者农用车不同农作物生长阶段所需的浇灌、喷洒量不同，使农用车的载重量及行进难度有所不同，但是目前农用车大部分为恒定输出功率的设备，在需要超出输出功率的动力需求时，或者动力装置发生损坏时，就需要更换另一个功率更高的农用车，造成需要置备多种农用车进行农田作业，从而不能充分利用每台农用车，也增加使用人的设备采购成本。在更换作业地点时，农用车需要在其他车辆的拖动下快速转场，此时农用车的电机链轮会随着拖车快速转动，不利于电机的寿命保持。
发明内容

所述的链状传动结构40为如图1所示传动链或者如图2-3所示的由若干滚子均匀排列形成的传动装置；所述的链状传动结构40设置在所述轮缘70的正面或者侧面，从而使所述的电机30位于车轮20的左侧、右侧或者上方，例如图1所示的电机30处于车轮20的内侧，如图2所示的电机30处于车轮20的外侧，如图3所示的电机30处于车轮20的正上方，此时链轮50可以设计为与电机30为一体。
为了使链状传动结构40的链条或者棍子之间不易卡入田间杂物，所述的链状传动结构的节距为链轮齿距的2倍或以上。
为了使所述车轮的整体重量减轻，如图6-8所示，所述的轮缘70设计为适当的宽度，本发明中轮缘70的宽度大于30mm小于100mm，这样既可以维持车轮20整体较轻的重量，又不易于在行走过程中车轮陷入泥土中。所述的轮缘70易于与轮缘外侧的防滑装置连接，也易于与内侧的轮辐连接。具体来说，所述的轮缘70的外圈为圆周面，并且轮缘上均匀的设有多个通孔，用于固定轮缘外侧的防滑装置；所述轮缘70的内圈为中间凹进、两边凸起72的U形结构，便于轮缘与轮辐的固定。
为了进一步减轻车轮20的重量及避免车轮绞缠农作物，所述的轮辐采用薄钢板，且所述的轮辐为若干如图9所示的扇形薄钢板80拼接而成的整体无开孔的圆环形。所述扇形薄钢板80的两边向上弯折形成加强骨81，以及中心凹陷形成T形槽状加强骨82，且所述若干扇形薄钢板正反交替焊接固定。
为了增强车轮20的耐磨性以及防滑性，所述的轮缘70外圈上固定有防滑胶块95，所述的防滑胶块95可以通过轮缘70上的通孔与轮缘固定。所述的防滑胶块95的高度大于20mm小于40mm，所述的防滑胶块95为橡胶块。并且所述的防滑胶块95至少设置两排，两排防滑胶块95左右交错相对设置。为了增强轮缘防滑胶块的固定及因损坏而进行更换的效率，若干防滑胶块95与一段支架91固定形成一个防滑单元90，如图11-12所示，所述的防滑胶块95为支架91上的金属立柱94和金属立柱95包裹橡胶而形成。所述的金属立柱由三个金属片在相邻三个面大致垂直相交形成。每个防滑胶块内设有两个 所述的金属立柱，所述的两个金属立柱呈对角相对设置在所述的支架上。所述金属立柱94和金属立柱95与所述支架91为一体制造的金属结构。
所述支架与轮缘接触的面为弧形，设有两个以上，每个支架弧长小于二分之一轮缘周长，本实施例中，优选每个支架91的弧长为四分之一轮缘周长。如图10所示，所述两个以上的支架91通过支架固定孔92与轮缘70固定安装在一起并且组成一个完整的圆环。如图12所示，所述的支架中轴线上设有若干棍子41，所述棍子按照一定节距均匀排列在支架的上面，且棍子之间互相平行。所述的支架91中间设置棍子、两侧通过金属立柱固定防滑胶块，防滑胶块交错对应设置，共同形成新的防滑单元90，然后再将诉述防滑单元全部固定在轮缘上。
为了使作为驱动器的电机可以根据农用车的动力需求方便置换，以满足农用车不同的使用情况，所述驱动器或者电机为可拆卸更换式。如图13、14、15所示，所述驱动器上的链轮50通过一链轮架130与农用车本体10连接，所述的电机的一侧与链轮可拆卸式连接，另一侧与一驱动器架120连接，所述的驱动器架120与所述链轮架130可拆卸式连接。所述电机30的中心设有螺栓150，所述驱动器架120的中心设有螺栓孔，电机30上的螺栓穿过驱动器架120上的螺栓孔使电机30与驱动器架120通过螺栓螺母连接。所述的电机30外侧设有驱动器保护罩150，所述的驱动器保护罩130与驱动器架120焊接固定。所述的链轮外侧设有链轮罩100，所述的链轮罩100上设 有固定孔，所述的链轮50的传动轴140穿过所述的链轮罩100的固定孔使链轮罩100与链轮50固定连接。所述链轮架130位于链轮与驱动器之间并与链轮和驱动器的连接轴固定；所述的驱动器架120为一V形钢板，所述的V形钢板的中心与电机螺栓固定，所述的V形钢板的两端焊接有钢管，所述钢管与链轮架130上对应位置的螺栓柱嵌套连接。
如图16所示，所述的链轮50的中心设有一传动轴140，所述的传动轴140与驱动器中心的螺栓150连接，使电机30带动链轮转动。
为了使所述电机在农用车转场等情况下，不需自身动力运动时，电机与车轮脱离啮合，以保护电机寿命，所述的电机及链轮涉及为可以离合的结构，具体如图17所示，包含链轮固定块170，离合器160，固定链轮和电机的链轮架130，所述的链轮架130上设置离合器160。
如图17所示，所述的离合器160包含固定部和握持部，所述的固定部为圆柱形，所述固定部穿过链轮架130，并在水平方向相对于链轮架进行一定距离的移动。所述的握持部与固定部一体制造并整体呈T形。所述的固定部上套有一弹簧，弹簧的一端为凸台161，另一端设有卡簧180，所述卡簧180位于远离握持部的一端，凸台161位于靠近握持部的一端，所述固定部上设有卡簧固定槽，所述的卡簧嵌入卡簧固定槽并与弹簧的一端连接。
如图18-21所示，所述的链轮架130通过链轮固定块170与一立柱190转动连接，所述立柱190为农用车本体的一部分。所述的链轮固定块170上还设有一高一低两个定位孔，分别为高定位孔171和低 定位孔172，所述的离合器160与链轮固定块170上的高定位孔171固定时，所述的链轮50处于如图20和21所示的与车轮20脱离啮合状态，即非啮合或者离合状态；所述的离合器160与链轮固定块170上的低定位孔172固定时，所述的链轮50处于如图18和19所示的与车轮20啮合的状态。
以上实现的农用车，采用电机等驱动器驱动，电机驱动车轮边缘以及电机在损坏或者需要不同动力时，可以快速更换；在农用车不需要动力供给即可移动时，可以将电机与车轮脱离啮合，非常方便各种农田作业，且车轮轻便，不易碾压农作物。
