Description

四轮二组前后驱动履带式稻麦联合收割机
技术领域
本发明涉及一种农业机械, 进一步是指一种四轮二组前后驱动履带式稻麦 联合收割机。
背景技术
现在各地使用的稻麦联合收割机, 无论大、 中、 小型, 不外乎轮式行走或 履带式行走, 由于自身质量较重, 移田困难, 易于陷泥, 均不适宜山区、 丘陵 地区、 稀泥田、 狭小梯田中作业。 新近出现的微型收割机, 行走机构采用单个 大滚轮及链条链轮传动, 作业时卡泥缠草, 也不适宜在稀泥及半湿泥水田中作 业; 所述大滚轮没有动力转向而是靠人力实施, 其转向困难, 操作难度大, 消 耗体力大, 不适宜小块田中作业。 多年来, 不少人力图研制出适于山区、 丘陵 地区水田作业的联合收割机, 但至今仍未见到切实可行的产品出现, 其主要障 碍是行走轮(机构) 的适应性未有突破性进展。
发明内容
本发明要解决的技术问题是, 针对现有技术存在的缺陷, 研制一种四轮二 组前后驱动履带式稻麦联合收割机, 它的行走轮采用前、 后两组共四个圆筒形 轮体并可相应设置轻型履带而有效增加了对地接触面积, 不会陷泥; 所述行走 轮具有机械变速、 转向、 行走、 离合功能, 使整机的性能稳定、 运行灵活、 操 纵方便省力, 适于山区、丘陵的梯田、 小块田、深泥脚田、半湿水田收割作业。
本发明的技术解决方案是, 所述四轮二组前后驱动履带式稻麦收割机包括 底盘和行走轮, 其结构特点是, 所述底盘的后端中部固定安装有变速箱, 该变 速箱两侧各有一根输出半轴且其上相应安装有随轴转动的圆筒形主动行走轮, 所述底盘前端的承重轴上并列安装有两个圆筒形从动行走轮, 所述主动行走轮 和从动行走轮之间装有联动机构。
以下对本发明做出进一步说明。
参见图 1, 本发明包括底盘 1和行走轮, 其结构特点是, 所述底盘 1的后 端中部固定安装有变速箱 14, 该变速箱两侧各有一根输出半轴 171、 172且其 上相应安装有随轴转动的圆筒形主动行走轮 181、 182, 所述底盘 1前端的承重 轴 19上并列安装有两个圆筒形从动行走轮 201、 202,所述从动行走轮 201、 202 与主动行走轮 181、 182之间装有联动机构。
为了进一步降低整机对地面的压强而更有利于在水田中作业, 如图 2和图 3所示, 还可在主动行走轮 181、 182与从动行走轮 201、 202的外周上设置履 带; 其一种实施例结构是, 在主动行走轮 181、 182和从动行走轮 201、 202上 设置齿 63并在该二行走轮上安装行走履带 451,该行走履带 451的中间部位设 有相应的齿孔 65, 行走履带 451的外表面设有行走齿 64。 即主动行走轮 181 与从动行走轮 201上设有一条履带, 主动行走轮 181与从动行走轮 202上设有 另一条履带。 , 上述履带结构还可做为所述从动行走轮 201、 202与主动行走轮 181、 182 之间所设置的所述联动机构。 , 所述从动行走轮 201、 202与主动行走轮 181、 182之间所设置的联动机构 的另一种实施例结构是(参见图 1 ), 在两根输出半轴 171、 172的外端分别装 有链轮 231、 232而在两从动行走轮 201、 202的外端装有对应的链轮 471、 472, 且两链轮 231、 271以及两链轮 232、 472之间分别装有传动链条 461、 462。 还 可在输出半轴 171与链轮 231之间, 以及输出半轴 172与链轮 232之间分别安 装离合器, 或者是在两从动行走轮 201、 202的外端与对应的链轮 471、 472之 间分别设置离合器 (参见图 4)。 所述从动行走轮 201、 202与主动行走轮 181、 182之间所设置的联动机构 的再一种实施例结构是(参见图 4), 所述输出半轴 171、 172外端分别装有伞 齿轮 351、 352,所述从动行走轮 201、 202外端面上装有对应的从动伞齿轮 481、 482,十字轴 491装在伞齿轮 351与伞齿轮 481之间且其两端分别有伞齿轮 551、 561与该两伞齿轮 351、 481分别相啮合, 十字轴 492装在伞齿轮 352与伞齿轮 482之间且其两端分别有伞齿轮 552、 562与该两伞齿轮 352、 482分别相啮合。 还可在所述十字轴 491、 492上设置离合器。

如图 1、 4、 5所示, 还可在所述两从动行走轮 201、 202相邻两端面上分 别设置互相套接的防卡缠连接圈 30、 31。
本发明的技术原理是, 行走机构采用了研制者经反复研究、 几十上百次试 验而优选确定的四轮二组圆筒式行走轮, 并进一步在两组行走轮上配置履带, 成数倍地大大增加对地接触面, 因为行走轮为中空圆筒结构, 自重小, 而使之 成为浮动行走轮, 故在水田作业中双轮均不会陷入泥中; 采用前后驱动机构使 整机越障能力及水田行走能力强; 选用具有离合、 转向、 变速、 传动四大功能 的变速器, 使整机性能稳定、 运行灵活、 操作方便、 省力。
由以上可知, 本发明为一种四轮二组前后驱动履带式稻麦联合收割机,,适 于山区、 丘陵的梯田、 小块田、 深泥脚田、 半湿田收割作业而不会陷入泥中, 整机性能稳定、 能耗小、运行灵活、越障能力强, 操纵方便省力, 还可拆易装、 移田方便。
