Description

一种双横并联分流低冲击脱粒分离装置 技术领域
本发明属于联合收割机脱粒分离装置领域，尤其是涉及一种双横并联分流低冲击脱粒分离装置。
背景技术
脱粒分离系统是联合收割机的核心工作部件，其脱粒性能直接决定了整机的工作性能。在水稻脱粒方面，国内外开发出了纵流脱粒装置、横轴流脱粒装置、切纵流组合式脱粒装置等脱粒结构；专利CN201280048847.6发明了一种加长物料脱粒分离的脱粒装置，极大的提高了农作物的脱粒行程和脱粒时间；专利CN201110298025.0发明了半喂入脱粒分离装置，该装置仅对水稻穗头进行脱粒，茎秆不喂入脱粒滚筒极大的降低了脱粒功耗；专利CN201410136610.4发明了一种双纵轴流滚筒负压喂入分流装置，该装置脱粒通过双滚筒增加了脱粒效率；专利201510192840.7发明了一种通过电动机带动的脱粒装置，采用电机代替发动机。现有脱粒装置在稻麦类收获指标上已基本满足国家要求，但脱粒系统在工作时存在功耗大、脱粒滚筒的冲击大、脱粒装置振动大、经脱粒后籽粒破碎率高等问题，严重制约着我国联合收割机向高品质高端机型发展。国外高端联合收割机脱粒装置类型较多，但我国联合收割机脱粒装置的与国外同类型相比存在较大不同，(1)国外机型主要针对旱作物收获较多，专用于水稻脱粒装置的结构及产品较少；(2)随着我国高产水稻产量增加(水稻“Y两优900”亩产1006公斤)，茎秆越来越粗壮，茎秆韧性越来越大，与国外旱作物相比对脱粒装置要求更高；(3)为缩短作物的生长时间提高产量，水稻在提前收获时茎秆的含水率较高，脱粒分离难度较大；(4)受现有发动机技术限制，适合联合收割机所需大马力的发动机较少，整机动力配置也成为收割机发展的一大瓶颈。
现有脱粒装置的主要有横轴流、纵轴流、横轴流与纵轴流组合三大类，纵轴流脱粒装置可以通过加长脱粒滚筒提高脱粒效率，但在加大脱粒滚筒长度时，对整机清选带来极大的困难，脱粒后籽粒的损伤也较大；横轴流多滚筒脱粒装置便于清选，但脱粒效率较低且脱粒过程中的振动较大。现有传统的高效脱粒分离装置设计主要是依据增加茎秆脱粒行程(脱粒时间)来提高工作效率和提高脱粒效果，但存在功耗大、破碎率高、脱粒滚筒冲击大和振动大的难题。
发明内容

本发明的有益效果：
(1)本发明所述的一种双横并联分流低冲击脱粒分离装置，通过初脱喂入装置将物料分成作物A部和作物B部两组；喂入作物A部进入到分流脱粒装置I内由分流滚筒I进行脱粒，脱粒后经分流脱粒装置I的A排草口排出；喂入作物B部经分流脱粒装置I的B排草口直接喂入到分流脱粒装置II内，由分流滚筒II进行脱粒；经分流滚筒I和分流滚筒II脱粒后的作物均由分流脱粒装置II的AB排草口喂入碎草装置；通过将切流滚筒初脱分离后的茎秆进行分流脱粒，极大的减轻了后续滚筒的脱粒负担；针对初脱后的难脱籽粒设置分流滚筒脱粒参数，极大的提高了脱粒效果；通过分流减少了分流滚筒脱粒的负荷，减少了脱粒过程中滚筒的不平衡和振动现象。
(2)本发明的结构布置和外形尺寸与现有履带式联合收割机匹配，可以直接替换现有履带式联合收割机上脱粒装置，也可以将本发明直接应用在现有结构尺寸的履带式水稻联合收割机上，减少了与本发明配套的联合收割机相关零部件研发成本，极大的提高了本发明的通用性和普适性。
(3)本发明通过在将输送槽喂入到初脱喂入装置的茎秆采用钉齿脱粒元件脱粒，茎 秆受打击后变软，在切流滚筒初脱作用下茎秆上成熟度高易脱籽粒被脱粒，未脱籽粒极大减少，有效减少了后续的难度；同时切流滚筒也具有初脱功能，将已脱粒籽粒进行分离，减少茎秆中籽粒夹带量，减少滚筒后期分离的负担；从而实现了依据作物成熟度进行分级脱粒并减少籽粒损伤程度的功能，降低了籽粒的破碎率。
(4)本发明通过将滚筒钉齿安装在滚筒齿杆上呈后倾3～5°夹角，极大的提高了脱粒滚筒在脱粒滚中钉齿的缠草及脱粒装置堵草的问题；通过在滚筒导流板内侧设计锯齿，提高了物料的输送能力，减少了脱粒滚筒运动中茎秆的回流；通过将脱粒部的导流板设置成由入口至出口宽度逐渐减小的偏心圆环，可以增加茎秆在输送过程中的分层和茎秆的相对运动，提高籽粒的分离效果。
(5)本发明通过在初脱喂入装置的AB排草口位置采用切流半脱粒凹板筛辐条，使得茎秆在输送过程中也具有一定的籽粒脱粒和分离功能；在分流滚筒II排草位置设置分流滚筒II输送凹板筛辐条，可以减少茎秆在排草口位置的脱粒阻力，提高茎秆的输送能力，防止茎秆在排草口被堵塞；本发明的半脱粒凹板筛辐条和输送凹板筛辐条均采用全脱粒凹板筛辐条结构改造，极大减少了发明过程中的模具开发和加工成本。
