Description

说明书 发明名称：一种单毯苗双插二维宽窄插秧机 技术领域
[0001] 本发明涉及一种农业机械装备， 尤其是涉及一种插秧机。
背景技术
[0002] 传统的水稻栽培一般都采用等行距的插植方法， 但是这种插植方法植株与植株 之间必然会出现遮阳的问题， 对通风、 通光都不利， 水稻的通风通光性直接影 响水稻的产量及病虫割的防治。 目前宽窄行插秧方法已经得到广泛的应用， 它 是窄行距与宽行距间隔栽培的一种水稻高产栽培技术。 该栽培方式既能保证单 位面积上的穴数合理， 又具有植株群体分布合理,通风透光性能好,光合作用率高 等优点,因此单产水平较高,是高产攻关常选择的栽培方式之一。 同吋， 由于通风 透光性增强， 使稻株间湿度降低， 可在一定程度上减轻病虫危害， 最终达到高 产增收的目的。 为了适应这种农艺的要求， 人们也设计出不各种不同的单毯苗 双插二维宽窄插秧机， 如公幵号为 CN10193342的中国专利公幵了一种斜齿轮传 动宽窄行插秧机分插机构。 在结构相同的左、 右齿轮盒内分别设置一套交错轴 斜齿轮传动,行星轮与中间倾斜齿轮为一对啮合的交错轴斜齿轮,使行星轴与齿轮 盒倾斜，从而使固结于行星轴的栽植臂与齿轮盒倾斜;栽植臂秧针的运动平面不再 与齿轮盒的回转平面平行,而是作空间运动,形成空间插秧工作轨迹;秧针从秧门取 秧位置运动到推秧点位置,秧针尖点产生横向位移,即垂直于机器前进方向的位移, 使秧苗入土点相对取秧位置有横向左移或右移,在现有的秧门等距分布前提下使 得插秧行距形成农艺要求的宽窄行相间分布。 这种结构使用于现有等距插秧的 插秧机的苗台， 就可以实现宽窄行插秧， 但这种结构如果秧针尖点产生的横向 位移过大， 即秧针的倾斜角度过大， 就会使得秧针在取秧吋对秧苗的伤害过大 ； 如果秧针尖点产生的横向位移过小， 即秧针的倾斜角度过小， 就会使得行距 变化很小， 达不到宽窄行插秧的农艺目的。 要解决这一问题， 人们也有一种技 术方案， 如公幵号为 CN10177954的中国专利， 公幵了一种单毯苗双插二维宽窄 插秧机， 其特征在于它包括秧箱、 分插机构、 移秧箱机构、 机架， 悬挂架以及 动力行走装置， 秧箱可在移秧箱机构的带动下在机架上进行横向的左右移动； 其特征在于： 分插机构的秧苗取插机构之间的间距按照宽行宽度、 窄行宽度间 隔地设置； 秧箱被按横向分成若干个秧毯放置单元， 单元与单元之间存在间隔 ， 所述单元内设有放置秧毯位， 其宽度为窄行宽度的两倍； 每个单元配设有两 个间距为窄行宽度的秧苗取插机构。 该技术方案中， 每个单元的两个秧苗的取 插机构的设置必然为， 第一个从秧毯的最前端幵始取秧， 第二个从秧毯的中间 幵始取秧， 这一点从其说明书可以看出， 这就使得通过该技术方案完成的插秧 ， 其窄行必然为毯苗单元宽度的一半， 以现有的标准毯苗为例， 宽度为 28CM， 其实现的窄行宽度为 14CM。 但目前的农艺研究表明， 这种窄行的宽度是过密的 ， 会影响水稻的生长， 而窄行宽度应该达到 16-18CM为宜， 因此， 要达到这个宽 度， 就需要培育出 32-36CM宽的毯苗， 这显然需要全面对现有的毯苗培育设备进 行改造更新， 造成很大的浪费。 这也是该技术方案没有得到实际推广的一个重 要原因。
技术问题
[0003] 本发明主要是解决现有技术所存在的宽窄行插秧机的秧苗损伤严重， 难以适应 现有毯苗宽度等的技术问题， 提供一种能够在保护秧苗的情况下， 利用现有的 毯苗培育设备， 在用标准毯苗的情况实现达到农艺要求的二维宽窄插秧机。 问题的解决方案
技术解决方案
[0004] 本发明的上述技术问题主要是通过下述技术方案得以解决的： 一种单毯苗双插 二维宽窄插秧机， 包括车体、 苗台以及插植机构， 所述的苗台包括若干个苗板 ， 所述的插植机构由驱动箱、 回转箱构成， 每个回转箱上设有前后两个插植臂 ， 插植臂上设有插秧爪， 其特征在于所述的苗板与苗板之间设有一个空位， 每 个苗板对应设有两个取秧位， 每个取秧位对应设有所述的回转箱以及相应插植 臂和插秧爪， 两个取秧位的间距为苗板可放毯苗宽度的二分之一， 同一个苗板 对应的两个所述的回转箱的回转轨迹圆相互构成一个夹角， 使得两者的插秧爪 的插秧点相对于两者的取秧点向两侧偏移， 各所述的驱动箱为非均速输出驱动 箱， 其输出的转动动力在旋转一圈的过程中完成一次快慢交替， [0005] 若将旋转一圈定为一个周期 T， T=T1+T2， Tl为转速较高的吋间段， T2为转速 较低的吋间段， 则在 T1吋段内前后两个插植臂及其插秧爪分别完成一次取、 插 秧。
[0006] 本发明的回转箱的回转轨迹圆指的是， 在回转箱上取一个非回转中心的点， 在 回转箱转动一周的过程中， 该点所走过的轨迹。 本技术方案中， 同一苗板对应 的两个所述的回转箱的回转轨迹圆相互构成一个夹角， 使得插秧点不是处于取 秧点的正下方， 而发生偏移。 通过这一技术设置， 使得对应的两个插秧点比对 应的两个取秧点的间距更大。 由于这里的两个插秧点正好是窄行， 它的偏移距 离一般在 1-2CM, 而两者分别向两侧偏移， 所以， 其实际的间距变大 2-4CM, 因 此其既实现了窄行宽度适当放大， 又不会因为插秧爪倾斜角度过大而伤害秧苗 。 本发明的宽行通过苗板与苗板之间设置的空位得到， 因此， 本发明可以实现 宽行和窄行都适当的宽窄行插秧。 本技术方案的重要意义在于， 以现有标准 （ 常用） 的毯苗宽度为基础， 现有技术中， 通过一个毯苗对应两个插秧爪实现的 宽窄行插秧中的窄行， 在农艺上是过窄的， 而本发明在这一点上实现了突破， 既利用了现有宽度的毯苗， 也实现合适的行距的宽窄行插秧。 本技术方案中的 驱动箱输出的转速的特点， 在车速均匀的情况下， 由于同一个回转箱上的两个 插秧爪分别快速完成一次取、 插秧， 尔后， 进行低速的转动过程中， 低速转动 过程中不插秧， 使得其在秧距的分布上也实现了宽窄间隔插秧。 因此， 本技术 方案完成的插秧在平面的两个方向上都实现了宽窄分布。
[0007] 作为优选， 所述的回转箱的转轴与所述的驱动箱输出轴之间通过一个变向机构 相连。 驱动箱的输出轴一般于苗台在工作中的移动方向相平行， 如果回转箱的 转轴在连接驱动箱的输出轴是不进行变向的话， 则回转箱的转动轨迹圆必然与 苗台的移动方向相垂直， 各回转箱的转动轨迹圆之间也相互平行， 不存在夹角 。 因此， 本技术方案通过一个变向机构， 使得回转箱转轴与驱动箱的输出轴之 间的不平行、 不同轴， 而具有一个夹角， 实现两个对应的回转箱的回转轨迹圆 相互构成一个夹角。 该变向机构所变向的角度大小决定了同一苗板对应的两个 回转箱的转动轨迹圆之间的夹角的大小。
[0008] 作为优选， 相邻两个苗板之间设有一个双输出驱动箱， 双输出驱动箱的两侧分 别设有一个所述的回转箱分别与该侧的苗板相对应， 左右两端的苗板还分别设 有一个单输出驱动箱， 该单输出驱动箱设有一个回转箱， 与左 \右端的苗板对应 ， 形成一个苗板对应两个回转箱的布局。 该技术方案使得双输出驱动箱的两侧 回转箱不对应于同一个苗板， 而分别对应于两个相邻的苗板， 由于同一个苗板 对应的两个回转箱的位置较近， 这两者之间的空间非常有限， 难以布置一个驱 动箱。
[0009] 作为优选， 所述的苗板的下端中部设有毯苗分割板， 苗台处于最右侧吋， 苗板 对应的两个取秧位分别处于苗板的最或端和毯苗分割板的右侧。 本发明在使用 吋， 同一苗板对应的两个取秧位同吋由插秧爪取秧， 一个从左端幵始取， 一个 从中部幵始取， 随着苗台向左移动， 取秧点的位置相对于苗台向右移动， 直到 左侧的取秧点到达苗板的中部， 右侧的取秧点到达苗板的最右侧， 此吋， 理论 上， 左侧了秧点对应该行秧苗前半部的最后一根秧苗， 但如果这根秧苗是的左 右两侧均没有任何约束面， 这根秧苗在就容易倒， 而使得插秧爪根本取不到秧 苗， 同理， 当苗台从左往右移动吋， 即取秧点相对于苗台从右往左移动， 右侧 取秧点到达最后一根秧苗吋也具有同样的情况。 因此， 本技术方案在苗板的中 部下端设有一个毯苗分割板， 在毯苗向下移动的过程中， 其对毯苗形成分割， 并达到对其两侧的秧苗的约束作用。
[0010] 作为优选， 所述的毯苗分割板包括一个用于将其固定在苗板上的底板， 和一个 垂直于底板的分割板， 该分割板上端为尖角， 贴合于固定板， 下端翘起， 构成 一个斜向上的切割刃。 该切割刃对毯苗具有很好的切割作用。
[0011] 作为优选， 所述的苗板可放毯苗宽度为 28CM， 同一苗板对应的两个取秧点的 间距为 14CM， 即同一苗板对应的两个插秧爪的取秧点的间距为 14CM， 这两个 插秧爪的插秧点的位置分别为： 左侧插秧爪的插秧点相对于其对应的取秧点向 左偏移 1-1.5CM; 右侧插秧爪的插秧点相对于其对应的取秧点向右偏移 1-1.5CM ， 即作为窄行， 这两个插秧点的间距为 16-17CM。 该技术方案中， 苗板可放的毯 苗为 28CM， 这是一种推广最为广泛的毯苗尺寸， 现有大量育苗设备均为该尺寸 ， 插秧点相对于取秧点偏移后实现的 16-17CM的秧苗间距是宽窄行插秧技术中的 合理的窄行宽度， 本技术方案有效的实现了单片 28CM的毯苗完成两行插秧， 且 间距大于毯苗宽度的 1/2， 达到合理的 16-17CM。 并且， 由于单个插秧爪从取苗 到插秧的横向偏移距离较小， 其相到秧苗的倾斜角度较小， 不会对秧苗造成实 质性的伤害。

本发明的实施方式
[0016] 下面通过实施例， 并结合附图， 对本发明的技术方案作进一步具体的说明。
[0017] 实施例 1 :
[0018] 如图 1所示， 本发明是一种单毯苗双插二维宽窄插秧机， 包括车体、 苗台以及 插植机构， 所述的苗台包括 4个苗板 1， 所述的插植机构由驱动箱 2、 回转箱 3构 成， 每个回转箱上设有插植臂 4， 插植臂上设有插秧爪 7， 所述的苗板与苗板之 间设有一个空位 8， 每个苗板对应设有两个取秧位 5， 每个取秧位对应设有所述 的回转箱每个回转箱上设有两个插植臂， 插植臂上设有插秧爪。 两个取秧位的 间距为苗板可放毯苗宽度的二分之一。 回转箱的转轴与所述的驱动箱输出轴之 间通过一个变向机构相连， 同一个苗板对应的两个所述的回转箱的回转轨迹圆 相互构成一个夹角， 使得两者的插秧爪的插秧点相对于两者的取秧点向两侧偏 移。 各所述的驱动箱为非均速输出驱动箱， 其输出的转动动力在旋转一圈的过 程中完成一次快慢交替，
[0019] 若将旋转一圈定为一个周期 T， T=T1+T2， Tl为转速较高的吋间段， T2为转速 较低的吋间段， 则在 T1吋段内前后两个插植臂及其插秧爪分别完成一次取、 插 秧。
[0020] 本发明本在使用中， 从同一苗板取下的秧苗所插的两行秧为窄行， 相邻两个苗 板取下的相邻两株秧所插的两行秧为宽行， 以些实现宽窄行插秧。 一苗板对应 的两个所述的回转箱的回转轨迹圆相互构成一个夹角， 使得插秧点不是处于取 秧点的正下方， 而发生偏移。 通过这一技术设置， 使得同一苗板对应的两个插 秧点比对应的两个取秧点的间距更大。 由于这里的两个插秧点正好是窄行， 它 的偏移距离一般在 1-2CM, 而两者分别向两侧偏移， 所以， 其实际的间距变大 2- 4CM， 因此其既实现了窄行宽度适当放大， 又不会因为插秧爪倾斜角度过大而 伤害秧苗。 本发明的宽行通过苗板与苗板之间设置的空位得到， 因此， 本发明 可以实现宽行和窄行都适当的宽窄行插秧。 本技术方案中的驱动箱输出的转速 的特点， 在车速均匀的情况下， 由于同一个回转箱上的两个插秧爪分别快速完 成一次取、 插秧， 尔后， 进行低速的转动过程中， 低速转动过程中不插秧， 使 得其在秧距的分布上也实现了宽窄间隔插秧。 因此， 本技术方案完成的插秧在 平面的两个方向上都实现了宽窄分布。
[0021] 实施例 2:
[0022] 如图 1、 图 2、 图 3所示， 本发明是一种单毯苗双插二维宽窄插秧机， 包括车体 、 苗台以及插植机构， 所述的苗台包括 4个苗板 1， 所述的插植机构由驱动箱 2、 回转箱 3构成， 每个回转箱上设有插植臂 4， 插植臂上设有插秧爪 7， 所述的苗板 与苗板之间设有一个空位 8， 每个苗板对应设有两个取秧位， 相邻两个苗板之间 设有一个双输出驱动箱， 双输出驱动箱的两侧分别设有一个所述的回转箱分别 与该侧的苗板相对应， 左右两端的苗板还分别设有一个单输出驱动箱， 该单输 出驱动箱设有一个回转箱， 与左 \右端的苗板对应， 形成一个苗板对应两个回转 箱的布局。 每个回转箱分别与一个取秧位对应， 每个回转箱上设有两个插植臂 ， 插植臂上设有插秧爪。 两个取秧位的间距为苗板可放毯苗宽度的二分之一。 回转箱的转轴与所述的驱动箱输出轴之间通过一个变向机构相连， 同一个苗板 对应的两个所述的回转箱的回转轨迹圆相互构成一个夹角， 使得两者的插秧爪 的插秧点相对于两者的取秧点向两侧偏移。 所述的苗板的下端中部设有毯苗分 割板， 苗台处于最右侧吋， 苗板对应的两个取秧位分别处于苗板的最或端和毯 苗分割板的右侧。 毯苗分割板 6包括一个用于将其固定在苗板上的底板 61， 和一 个垂直于底板的分割板 62， 该分割板上端为尖角 63， 贴合于固定板， 下端翘起 ， 构成一个斜向上的切割刃。 苗板可放毯苗宽度为 28CM， 同一苗板对应的两个 取秧点的间距为 14CM， 即同一苗板对应的两个插秧爪的取秧点的间距为 14CM ， 这两个插秧爪的插秧点的位置分别为： 左侧插秧爪的插秧点相对于其对应的 取秧点向左偏移 1.4CM; 右侧插秧爪的插秧点相对于其对应的取秧点向右偏移 1. 4CM, 即作为窄行， 这两个插秧秧点的间距为 16.8CM。 各所述的驱动箱为非均 速输出驱动箱， 其输出的转动动力在旋转一圈的过程中完成一次快慢交替， [0023] 若将旋转一圈定为一个周期 T， T=T1+T2， Tl为转速较高的吋间段， T2为转速 较低的吋间段， 则在 T1吋段内前后两个插植臂及其插秧爪分别完成一次取、 插 秧。
[0024] 本实施例中， 在苗板的中部下端设有一个毯苗分割板， 在毯苗向下移动的过程 中， 其对毯苗形成分割， 并达到对其两侧的秧苗的约束作用。 苗板可放的毯苗 的宽度为 28CM， 这是一种推广最为广泛的毯苗尺寸， 现有大量育苗设备均为该 尺寸， 插秧点相对于取秧点偏移后实现的 16-17CM的秧苗间距是宽窄行插秧技术 中的合理的窄行宽度， 本技术方案有效的实现了单片 28CM的毯苗完成两行插秧 ， 且间距大于毯苗宽度的 1/2， 达到合理的 16-17CM。 并且， 由于单个插秧爪从 取苗到插秧的横向偏移距离较小， 其相到秧苗的倾斜角度较小， 不会对秧苗造 成实质性的伤害。
