文档介绍：螺旋槽轮式小麦精量播种机
摘要
小麦精量播种机技术具有省种高产的优点,可使小麦苗匀、苗齐、苗壮,且能节约种子,降低成本,增加产量,受到广大群众的欢迎,因而小麦精量播种机己成为农户迫切需要的一种农业机械。
目前由于国内使用的小麦精量播种机都是机械式的,对种子的尺寸都有严格要求,而且容易造成一定的种子破碎率。本设计是根据国内外播种机的发展趋势,通用性和适应性不断提高以及本着结构简单操作灵活的原则,而设计的一种螺旋槽轮式小麦精量播种机。
本文就现有小麦播种机存在的问题,提出了设计方案,着重对播种机的排种器、开沟器、以及镇压轮等结构进行设计。该机可减少拖拉机功率消耗、降低作业成本, 为后续机械化作业打好基础。

ABSTRACT
Wheat planter precision technology advantage is to save seed yield of wheat seedlings to enable unified, Miao Qi, Miao, Zhuang, and can save the seeds, reduce costs, increase production, ed by the masses, it has e an urgent need for refined wheat planter farmers agricultural machinery.
     At present, the domestic use of good wheat planter machinery, seed size is required, but it may cause some seed crushing rate. To achieve the goal of high-yield crops, we must pay attention to agricultural and bination of reasonable precision sowing wheat can provide good growing conditions. This design is now on the basis of domestic and foreign R & D planter, for versatility and adaptability of continuous improvement, with a simple and flexible operating principles for the design, the design of the spiral groove wheel refined wheat planter.
In this paper, the design of wheat planter raised questions focused on planting row planter, bottle opener, and the suppression of the wheel structure design choices. This machine can reduce the energy consumption of tractors, reduce operating costs, provide a basis for subsequent mechanization.

1 概述
国内:国家从1990年代开始发展精密播种机械,在1980年代,中国开发了半精细耕作作的小麦播种机,但种子大小不均,土地整理不好,机械发展中没有重大突破,许多因素限制了小麦精密播种机的
