烟草智能装盘播种机的设计

摘要

This paper designs a 200-pit-tray tobacco intelligent plate planter .For meeting the requirements of tobacco floating-seedling intensity , run the operations at scale , and mechanizing , and to reduce the labor intensity of tobacco farmers and boost working efficiency ,this machine can automatically convey the plate ,matrix filling and compacting , see-ding,watering and matrix recovering .Bi-scraper is adopted in this machine .It makes the matrix fill and compact twice in one operation .It also makes the pits regular and easy to seed .Single-double sowing is achieved via a program controlled step motor .This machine distributes seed evenly , adjustable and high efficiency .The machine has many obvious strong points as compact structure , smaller volume , easy to operate and remove and low power requirements .%为了更好地满足烟草穴盘漂浮育苗工厂集约化、规模化、机械化的需要，以达到有效地降低广大烟农的劳动强度，提高劳动效率，设计了一种200穴苗盘烟草智能装盘播种机。该机具以1台单相异步电动机和1台步进电机为动力源，可1次完成自动送盘、基质填充、压实压穴、播种、淋水裂解、二次覆基质等多项作业。采用旋转滚筒式落料装置使基质雨状散落，使基质均匀下落；采用双刮板双压穴装置使落入穴中的基质得到2次压实和2次填充，实现盘穴穴坑形状规则，为播种打下基础；采用程序控制步进电机驱动的播种装置实现单双粒播种。该机具可以达到播种均匀、可控和高效的目标，同时具有结构紧凑、体积小、便于移动、操作简单和动力消耗小等优点。
