Description

一种用于半自动移栽机的钵苗自动喂苗机构 技术领域
本发明为一种高效的钵苗喂送机构，该机构应用于蔬菜、花卉等钵苗移栽机的分苗与喂苗作业，特别涉及一种应用于钵苗喂送过程的机构，属于农业机械技术领域。
背景技术
钵苗移栽主要优点如下：①、缩短生长周期，有利茬口安排，提高土地利用率；②、移栽后钵苗根系发达，可为后续管理等环节提供便利条件。蔬菜、花卉生产一直是一项劳动密集型产业，由于没有合适的配套机械，其劳动力成本占生产成本的50％以上，人工移栽作业劳动强度大，作业效率低，移栽质量差，且难以实现大面积移栽，进而导致生产规模小，生产效益低，制约我国蔬菜、花卉种植业的发展。机械化移栽能降低劳动强度、提高作业效率和钵苗成活率，还能提高经济效益和社会效益，与直接播种相比具有很大的优势，越来越受到蔬菜、花卉生产者的青睐。
喂苗机构的作用就是把钵苗实时送入栽植器中，现有半自动移栽机喂苗机构大都采用旋转托杯机构，一次只能喂入一棵幼苗，且不能间断操作；人工喂苗时劳动强度大，且操作员易疲倦而造成漏苗，降低移栽质量；受人工操作影响，移栽速度难以有效提升。全自动移栽机拥有一套自动喂苗机构，不需要人工喂苗，移栽速度增快，但整个机构比较复杂，成本很高，不适合中小规模用户，不适用于我国目前农业发展状况。用于穴盘苗移栽的自动取喂苗机构(申请号为201210317407.8)的发明专利公开了一种用于穴盘苗移栽的自动取喂苗机构，其包括移位机构、支架、滑杆、连杆机构和夹苗机构，支架设置于移位机构上，实现支架在取苗和喂苗动作之间的位置转换，滑杆一端插装于可在支架上滑槽内移动的滑套内，另一端与夹苗机构连接，通过移位机构实现夹苗机构在取苗和喂苗工序位置之间的转换，通过连杆机构控制滑杆和夹苗机构转动，并实现苗夹的闭合和张开，该装置结构比较复杂，生产成本较高，且其夹苗机构在夹苗过程中并不能精确定位钵苗位置，容易导致漏苗。机械喂苗移栽机的发明专利(申请号为201110133505.1)公开了一种替代人工向机械投苗系统投苗杯中喂苗的机械喂苗移栽机，可将穴盘内的苗一次多颗同步移入机械喂苗机构，喂苗机构由移栽机电控系统自动控制，以提高移栽作业速度和效率、降低生产成本，但其喂苗机构设计复杂、部件较多，此外，其采用传动链连续传动，会在两次喂放钵苗时产生不连续现象，导致钵苗落入托杯时的 托杯与钵苗配合时间的错误造成钵苗漏栽，而降低移栽质量。
发明内容
本发明针对当前移栽机喂苗机构的主要缺陷和不足，提出一种结构简单、高效可调移栽机钵苗喂苗机构及方法，通过一次放入多棵钵苗，提高喂苗系统效率，减小操作者的劳动强度，并提高移栽机的工作效率。
为实现上述目的，本发明技术方案如下：
一种用于半自动移栽机的钵苗自动喂苗机构，包括传动机构、曲柄滑块机构、挡杆9、侧板2、复位机构10和带轴承的轴承座12。所述传动机构包括传动轴Ⅰ5、传动轮3、传动轴Ⅱ8和传动轴Ⅲ11，所述传动轴Ⅰ5与传动轮3通过转动副E连接；所述传动轴Ⅱ8与传送带1通过转动副F连接；所述传动轴Ⅲ11与传送带1通过转动副G连接。所述曲柄滑块机构包括曲柄4、滑杆6和滑槽7，所述曲柄4与传动轮3通过转动副A连接，转动副A在传动轮3上，但不在转动轮3的圆心处；所述滑杆6与曲柄4通过转动副B连接；所述滑槽7与滑杆6通过移动副C连接；所述挡杆9与复位机构10通过转动副D连接；所述复位机构10与滑杆6固定连接。
所述曲柄滑块机构向右移动到极限点处时，挡杆9受到侧板2和复位机构10的作用，绕转动副D转动，末端正好转到侧板2的前端开口处；所述曲柄滑块机构向前移动到极限点处时，挡杆9在侧板2和复位机构10作用下能回到原始状态。所述的挡杆9的末端转动到侧板2上的极限位置时，电机都正好转动一个或多个脉冲，并控制传送带1进给一段预设距离。
在本发明的自动喂苗机构的工作实施中，挡杆9负责分苗，当栽植器接苗桶运动至接苗位置时，其同时触动用于喂苗的挡杆9，使挡杆9放开钵苗，钵苗在重力作用下落入栽植器接苗桶，也可落入传统移栽机用于分苗的旋转托杯中；挡杆9在放开一个钵苗后，在复位机构10作用下立即复位，以阻挡下一棵钵苗的连续喂入，并使下一棵钵苗在欲喂苗位置等待喂苗，以保障钵苗自动喂苗机构的功能实现。因此，本发明机构可单独直接使用于单行移栽机，也可将其2个或2个以上并列组合使用，以实现多行钵苗移栽机的多行自动喂苗移栽作业。
本发明的有益效果：本发明与现有技术相比，使移栽机械作业过程中钵苗的输送和分苗实现连续自动化，一次放入多棵钵苗实现了大于每分钟60株的连续机械自动化喂苗，满足高速自动移栽机的技术需求；一次放入多棵钵苗有效避免了操作者直接喂苗时 的频繁重复动作和怕漏苗的神经紧张造成的过度疲劳；结构简单，操作便利，降低操作者的劳动强度和移栽作业的劳动成本，提高移栽机的工作效率和移栽质量。

具体实施方式
下面结合附图以及具体实施例对本发明的结构、原理和工作过程做进一步的说明，但本发明的保护范围并不限于此。
图1为本发明提供的用于半自动移栽机的钵苗自动喂苗机构，其特征在于：包括传动机构、曲柄滑块机构、挡杆9、传送带1、侧板2、复位机构10和带有轴承的轴承座12。所述传动机构包括传动轴Ⅰ5、传动轮3、传动轴Ⅱ8和传动轴Ⅲ11，所述传动轴Ⅰ5与传动轮3通过转动副E连接；所述传动轴Ⅱ8与传送带1通过转动副F连接；所述传送带Ⅲ11与传送带1通过转动副G连接。所述曲柄滑块机构包括曲柄4、滑杆6和滑槽7，所述曲柄4与传动轮3通过转动副A连接转，转动副A在传动轮3上，但不在传动轮3的圆心处；所述滑杆6与曲柄4通过转动副B连接；所述滑槽7与滑杆6通过移动副C连接；所述挡杆9与复位机构10通过转动副D连接；所述复位机构与滑杆6一端铰接。
图2为钵苗自动喂苗机构的曲柄滑块机构示意图，图3为曲柄滑块机构的滑动极限 位置示意图。所述传动轮3转动半圈，曲柄滑块机构向右滑动；若传动轮3继续转动，则向左返回滑动，其极限位置如图3所示。
图4为钵苗自动喂苗机构的喂苗挡杆在滑杆推动下向右运动到达极限时的位置示意图；所述挡杆9在滑杆6推动下向右运动，同时因复位机构10的作用绕着转动副D转动，到达极限位置；当滑杆6返回运动时，挡杆9回复到原始位置。整个动作就是一棵钵苗下滑至导苗桶，另一棵钵苗随传动带1平移一小段距离后被挡杆9挡在投苗位置的过程。
本发明用于半自动移栽机的钵苗自动喂苗机构的喂苗过程，按如下步骤进行：
a)、操作者一次将多株钵苗放入传动带1上，动力通过传动轴驱动传送带1上的钵苗向前移动至挡杆9前的预喂苗位置。
b)、挡杆9负责分苗，当栽植器接苗桶运动至接苗位置时，其同时触动用于喂苗的挡杆9，使挡杆9放开钵苗，钵苗在重力作用下落入栽植器接苗桶(也可落入移栽机用于分苗的旋转托杯)中实现喂苗。
c)、挡杆9在喂入一个钵苗后，在复位机构10的作用下立即复位，阻挡下一棵钵苗的连续喂入，并使下一棵钵苗在欲喂苗位置等待喂苗，以保障钵苗自动喂苗机构的功能实现。至此，喂苗系统完成一个钵苗的完整喂苗过程，并开始下一个循环。
d)、操作者将前一组钵苗放入传送带1后同时准备好下一组钵苗，待机放入传送带1上，以保障待移栽钵苗能连续喂入。按如上次序即可实现半自动移栽机钵苗自动喂苗机构的连续喂苗，不仅降低工人的劳动强度和移栽作业的劳动成本，而且提高移栽机的工作效率，并可使移栽速度大于每分钟60株。
所述实施例为本发明的优选的实施方式，但本发明并不限于上述实施方式，在不背离本发明的实质内容的情况下，本领域技术人员能够做出的任何显而易见的改进、替换或变型均属于本发明的保护范围。
