Description

一种基于齿轮齿条传动的分苗装置 技术领域
本发明属于农业自动化设施中的移栽机分苗领域，具体涉及一种基于齿轮齿条传动的分苗装置。
背景技术
目前机械化移栽已经得到了较大的发展，移栽机种类繁多，功能多样。但是一般都是通用型移栽机。由于各种蔬菜秧苗的尺寸及物理特性存在一定的差异，对栽植要求如行距、株距、同一垄栽植行数也不尽相同，将通用型移栽机大规模应用于我国各种类型的蔬菜田具有一定难度。穴盘苗从最开始的育苗到移栽，中间有许多重复性的劳动，手工连续作业容易对人产生疲劳，容易出现漏苗和其他问题。穴盘的移栽能否实现自动高速显得尤为关键。
多行移栽机，比如富来威公司研发的一种半自动油菜苗移栽机。这种分苗装置由小型的拖拉机提供动力，拖拉机与移栽机之间采用三点悬挂的方法进行联接，前端有开沟器，使用链条钳夹式栽植器，4个人乘坐在上面投苗，能够进行4行移栽，由人工将油菜苗投入到钳夹上方苗盒中，随着钳夹的运动油菜苗被夹持到圆盘上做圆周运动，转到最低点时送到已经开好的苗沟中，钳夹打开，秧苗落入沟中，随后被镇压轮覆土压密。
而单行移栽机国内普遍采用圆形转盘式，栽植的苗杯一般直径比秧苗略大，以保证下落顺畅。其工作原理如是利用槽轮机构或者不完全齿轮传递间歇运动，苗杯在圆盘内转动，为使秧苗在苗杯中转动不至一夹苗根,直接让秧苗底部与转盘相互摩擦运动容易夹苗根，在苗杯底部设计有活门机构，使活门在行至落苗缺口处自然打开，落苗完成后能够顺利关闭。
国内外更多的是采用多环形输送链式分苗机构，比如井关的两行半自动蔬菜移栽机，单人乘坐式，带环形托杯，一个人可以完成2行的栽植器栽植任务。环形托杯在输送链的作用下转动，到达栽植器上方时，通过特殊的触发装置，可实现奇偶数错开落苗，栽植的苗杯一般直径比钵苗略大，以保证下落顺畅。其转动所需要的动力较单行移栽机固定转盘式较大，并且这种形式所需苗杯较多，重量过重。
如果设计不尽合理、受力及运动仿真不准确，容易造成分苗机构链轮峰值受力过大，动力不足，或者造成动力的分配不均。因此设计一种全新的，简易的分苗机构具有十分重要的意义。
