小区播种机净种系统的研究

Plot Seeder Seed-clearing System Research

小区播种机的性能是种子新品种培育的重要保障,其净种系统尤为重要。为此,就目前小区播种机上采用的几种净种方式进行研究,分析其组成结构和工作原理,同时对各种方式的优缺点进行剖析,以确定各种方式所适用的种子类型,为今后的小区播种机净种系统的研制提供一些参考。主要介绍了3种净种方式:1插装式,即采用可拆卸式排种装置,每次换种之前进行人工净种;2机械结构自动净种,利用特殊的结构造型在排种过程中自动清理剩余种子;3气吸式,根据气吸原理将剩余种子从排种器中吸出去。

Plot seeder performance is the important guarantee of seed breeding new varieties especially net system is particularly important. Net in this paper,the current community seeding machine adopts several kinds of ways to study,analyze its composition structure and working principle,analyzes the advantages and disadvantages of all kinds of ways and seed types,applicable to the various ways for future net kind of system to provide some references for the development of plot seeder. This paper mainly introduces the three ways: 1Net cartridge,namely the removable type metering device,every time before another manual net. 2Net,automatic mechanical structure with special structure model in the process of seed automatically clean up the rest of the seed. 3Gas suction,according to the principle of suction seed balance will be sucked out of the seed metering device.
