Description

一种秧苗移栽装置
技术领域
本发明涉及一种机械化自动秧苗抓取、开沟和秧苗投放的行距可调式秧苗移栽装置。
背景技术
近年来蔬菜移栽机迅猛发展，移栽秧苗的种类和移栽机结构均多样，但从取苗的方式上来看仍多采用人工“喂苗”的方式，效率比较低。由于机械喂苗这个环节未能实现技术突破，所以市场上的移栽机基本不能实现高效作业。并且市场上现有的移栽机功能单一，通用性差，机具性能不稳定。无法从根本上解决移栽时劳动强度大，移栽效率低，秧苗的准直度低的问题。
发明内容
本发明提供一种秧苗移栽装置，以解决蔬菜秧苗机械化自动移栽的问题。该装置能通过机械爪将蔬菜秧苗进行移栽，提高了秧苗移栽的准直度。
具体的本发明是通过如下技术方案实现的：
本发明提供的蔬菜秧苗移栽装置，其包括：机架、曲柄摇杆机构、摆架机构、开沟机构、移栽爪及压苗机构；所述机架包括顶块和立柱，其中顶块为两个且对称布置在机架的前端，立柱为一个，位于机架一侧；所述曲柄摇杆机构置于机架中部且与机架中的立柱同侧；所述摆架机构由摆杆、固定杆、旋转杆、伸缩杆、转动销组成，摆架机构位于机架中部；所述开沟机构通过固定杆放置在摆架机构顶端，所述移栽爪以及所述压苗机构固定在摆架机构的旋转杆上。
进一步地，所述摆架机构中的固定杆和旋转杆放置在机构的顶端，所述转动销放置在所述机架的立柱上，所述伸缩杆一端在转动销中伸缩，一端固定在旋转杆上，摆架机构中的摆杆与所述曲柄摇杆机构中的摇杆放置在同一根轴上。
进一步地，所述开沟刀与顶块组成的结构类似于凸轮顶杆机构，所述开沟刀由开沟板和拉簧组成，拉簧为两个位于开沟板两侧并且连接开沟板和旋转轴。
应本发明实施例，动力传入到秧苗移栽装置后，该秧苗移栽装置将秧苗的夹取、开沟和投放的动作先后连贯完成，解决了人工投喂苗的问题，提高了移栽机的作业效率实现了秧苗移栽的机械化。压苗机构在最低位置按压苗之后再将苗投放，保证了秧苗的准直度。

具体实施方式
结合附图可知秧苗移栽装置由机架、曲柄摇杆机构、摆架机构、开沟机构、移栽爪及压苗机构；摆架机构中的15摆杆通过轴与曲柄摇杆机构相连，机械爪及压苗机构分别安装在15摆杆的两侧，开沟机构由6开沟刀、16拉簧，配合位于机架上的5顶块，使得开沟机构类似于凸轮顶杆机构，最后由16拉簧将6开沟刀复位。6开沟刀和7机械抓手的间距均可调，可实现移栽时行距调整。
所述的摆架机构由15摆杆两个、17固定杆、18旋转杆及1伸缩杆组成，动力通过链轮传入到曲柄摇杆机构，其中曲柄摇杆机构中的14摇杆与15摆架由同一根轴相连，可实现同步运动，1伸缩杆与15摆架中的18旋转杆相连，当1伸缩杆在15摆杆运动过程中进行随动运动时，可带动18旋转杆进行90°的往复旋转。18旋转杆的往复旋转，带动机械爪和压苗机构的90°摆动。
所述的开沟机构在摆架机构运动的过程中带动着6开沟刀的运动，6开沟刀与5顶块组成的机构是类似于凸轮顶杆的机构，以此实现6开沟刀在移栽机行进方向上的前后移动，最后由16拉簧将6开沟刀复位。 整个机构结构简单，机械化程度高，蔬菜秧苗移栽的准直度高。
所述的7机械抓手固定在9电推杆上，18旋转杆进行90°的往复旋转，带动18旋转杆上的9电推杆转过90°，使得固定在9电推杆上的7机械抓手转过90°，利于蔬菜秧苗的夹取与投放。在此过程中7机械抓手实现了在最高位置夹取秧苗，在最低位置投放秧苗。
所述的压苗机构完成的的压苗动作是在投放秧苗的时候9电推杆伸到最长时完成的，之后将秧苗投放。
