Description

小型插秧机
技术领域
本发明涉及一种农业机械，特别是涉及一种插秧机。
背景技术
根据机插秧水稻的生长规律，插秧需满足以下要求才能使秧苗正常生长，从而达到提高水稻生产效率和产量的目的：1、栽植深度不能过深或过浅，过深将导致水稻生长慢，过浅将导致倒秧而降低成活率低，因此秧苗的栽植深度以保持在2～3cm为宜；2、田块水面不能过高，水面需保持在1～2cm左右；3、采用机械插秧时，在插秧的第一周内不能有过多的水淹没秧苗，但根部需保水以保证生长；4、田块地面要求平整，旋耕后需耙田平地以保证秧苗的栽植深度尽量一致。
CN201957435U 中公开了一种电动插秧机，包括拖板、机构传动臂、插秧臂、机架、移箱轴、拉杆、秧箱，机架固定在拖板上，在机架上设有直流电机、蓄电池，直流电机通过传动箱带动分插秧机构、移箱轴、送秧机构运动。直流电机与减速器连为一体。拖板沿插秧机前进方向设有凹槽，凹槽的位置与插秧臂的位置对应。
这种结构中，由于插秧臂运动的最低点与土壤的距离恒定，因此秧苗插入土壤的深度不能调节。但根据不同的气候土壤条件，却需要调整插秧深度以满足最佳的农艺要求，从而提高水稻产量。
插秧机工作时，启动电机，拉动拖板，使插秧机前行插秧。但是由于插秧机机架以上的重量直接作用在拖板上，因此拖板与水田之间的附着力较大，拖动插秧机较为吃力，并且在拖板前行起垄的过程中，拖板下部容易淤泥，不利于田垄成型。
因此本领域技术人员致力于开发一种可调节插秧臂与土壤相对高度的插秧机。
发明内容
有鉴于现有技术的上述缺陷，本发明所要解决的技术问题是提供 一种可调节插秧臂与土壤相对高度的插秧机。
为实现上述目的，本发明提供了 一种小型插秧机，包括拖板；所述拖板上安装有可旋转的机架；所述机架上安装包含 插秧臂、移箱轴、秧箱组成的 插秧机构和包含 传动臂、电池、电机组成的 动力装置，；所述 传动臂相对所述拖板和机架的连接点向后延伸； 所述 插秧臂安装在所述传动臂上并置于插秧机的前端 ；所述传动臂的尾部与拖板之间设置有高度调节装置，用于使机架相对拖板发生相对旋转运动，并可锁死所述拖板和机架的相对位置和距离。
为简化结构，降低成本，安装维修方便，并便于操作，所述拖板在所述连接点的后部左右两侧焊接有结构对称的第一支耳和第二支耳；所述第一支耳和第二支耳上设置有横管；所述传动臂的尾端固定有调节块；所述横管上套装有调节管；所述调节管上焊接有调节螺杆；所述调节螺杆穿过所述调节块；所述调节螺杆在所述调节块的上方和下方分别配合上调节螺母和下调节螺母。
为便于调节插秧臂高度，增加插秧机的稳定性，降低调节的劳动强度，所述拖板的中部焊接有横梁；所述横梁的左右两侧分别对称焊接有第三支耳和第四支耳；所述机架左右两侧分别与所述第三支耳和第四支耳通过螺栓固定连接。
为便于拉杆的安装，所述调节管设置在所述横管长度方向中心线的右侧或左侧。
为在自然状态下使拖板相对地面向上倾斜， 所述拖板与机架的连接点位于所述机架及机架上安装部件重心的后方，从而使所述拖板与地面的夹角为5-10°。
较佳的，所述连接点位于所述重心后方35-45mm处；所述夹角为7-8°。
本发明的有益效果是：
1 、本发明可根据不同的地质气候条件调节插秧臂的插植深度，以满足秧苗不同的农艺要求 ，因此大大提高了插秧机的适应性；
2 、本发明结构简单，重量轻，可由人力拖动整机，因此对田块的地质条件无特别要求，适应性广；
3 、本发明制造工艺要求低，大大降低了生产成本；
4 、本发明由于在前后方向上将机架与拖板的连接点设置于机架及机架上安装部件重心的前方，因此在自然状态下，拖板将相对地面向上倾斜5-10°，从而便于插秧机拖动前行，并利于拖板起垄成型。
附图说明

图2是图1中I处的局部放大图。
图3是图1中A向结构示意图。
图4是图1的俯视结构示意图。
图5是本发明一具体实施方式中拖板的结构示意图。
图6是图5的A-A剖视结构示意图。
图7是图5的B-B剖视结构示意图。
图8是本发明一具体实施方式的工作状态示意图。
具体实施方式
下面结合附图和实施例对本发明作进一步说明：
如图1至图8所示， 一种小型插秧机，包括拖板1，拖板1的中部焊接有横梁9，横梁9的左右两侧分别对称焊接有第三支耳1c和第四支耳1d，机架2左右两侧分别与第三支耳1c和第四支耳1d通过螺栓固定连接。
机架2上安装有包含 插秧臂10、移箱轴11、秧箱12组成的 插秧机构和包含 传动臂3、电池13、电机14组成的 动力装置。 传动臂3相对拖板1和机架2的连接点P向后延伸，插秧臂10安装在传动臂3上并置于插秧机的前端 。
拖板1与机架2的连接点P位于机架2及机架2上安装部件重心N后方的距离L为40mm，因此当机架2与拖板1连接好后，插秧机将重新寻找重力平衡点，从而使插秧机在水田工作时，拖板1与地面的夹角θ为8°。
在其他具体实施方式中，也可通过对机架2及其上部安装部件重量和位置布置等合理设计，使连接点P位于重心N后方35-45mm处的其他值，夹角θ为5-10°之间的其他值，以达到基本相同的技术效果。
拖板1在机架2和拖板1连接点P的后部左右两侧焊接有结构对称的第一支耳1a和第二支耳1b，第一支耳1a和第二支耳1b上铰接有横管4。
传动臂3的尾端固定有调节块5，横管4上套装有调节管6，调节管6上焊接有调节螺杆7，调节螺杆7穿过调节块5。调节螺杆7在调节块5的上方和下方分别配合上调节螺母8a和下调节螺母8b。
调节管6设置在横管4长度方向中心线4a的右侧，以便于安装拉杆15。在其他具体实施方式中，调节管6也可设置在横管4长度方向中心线4a的左侧，以达到基本相同的技术效果。
根据不同的地质气候条件，秧苗插入水田的深度需要适时调整，此时，只需松开第三支耳1c、第四支耳1d与机架2的连接螺栓，然后松开上调节螺母8a和下调节螺母8b，使机架2相对拖板1转动，从而使安装于传动臂3后端的左右插秧臂10运动的最低点与拖板1的竖直距离恰当，最后拧紧前述松开的各螺母即可。
由于连接点P位于机架2及机架2上安装部件重心N的后方，拖板相对水田地面16保持一个倾角θ向上倾斜，因此插秧机拖动前行时，拖板1与土壤之间的附着力将较小，便于拖动，并且拖板1下部凹槽起垄时不淤泥，利于拖板1起垄成型。
以上详细描述了本发明的较佳具体实施例。应当理解，本领域的普通技术人员无需创造性劳动就可以根据本发明的构思作出诸多修改和变化。因此，凡本技术领域中技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在由权利要求书所确定的保护范围内。
