Description

上置式脱粒半喂入联合收割机割台 技术领域
本发明涉及一种半喂入联合收割机，尤其涉及一种上置式脱粒半喂入联合收割机割台。
背景技术
现有的半喂入联合收割大都采用静液压无级变速操控收割作业，行驶速度、割刀的动作、夹持秸秆的输送链条的运行速度、拨禾与扶禾机构的运动速度都不随行驶作业速度变化，这带来收获作业不协调的状况影响作业效率，为改变这一状况，有的机型为扶禾机构增加运行速度调节的档位，但是没有根本改变其作业运行中存在多余的机构运动，浪费了能源。
现有的半喂入收割机的割台、脱粒夹持输送链、脱粒滚筒等功能部件的构建从前面直至后面组装在行驶底盘上，传动链长且多，工作流程路径长且复杂，不可能将这些收割功能部件较完整的拆卸下来，将行驶底盘在收割季节后挪作它用。
因机器重量重，且体积较大，不能够适应水田作业。水田都采用放干水后收割，因此是农业生产适应机械化，不是机械化适应农业生产。

在左侧护板11和右侧护板12的后侧顶部横向设置一支撑板17，支撑板17的两端分别与左侧护板11和右侧护板12固定。集粮筒14的上部敞开，集粮筒14的后侧固定连接在支撑板17上，集粮筒14的前侧伸向夹持输送链机构。中 间隔板13固定在集粮筒14的一侧，中间隔板13、集粮筒14和左侧护板11组成集粮斗。在脱粒滚筒1的上方设置脱粒滚筒上挡板38，脱粒滚筒上挡板38的后端与支撑板17固定连接，脱粒滚筒上挡板38的前端与压草板30固定连接。脱粒滚筒上挡板38的前端与集粮筒14的前端形成穗部入口。
拨禾机构包括挡板21、左拨禾传动总成和右拨禾传动总成。左拨禾传动总成和右拨禾传动总成均包括拨禾带盒22以及设置在拨禾带盒22内的拨禾主动带轮、拨禾从动带轮和拨禾传动带。拨禾传动带绕过拨禾主动带轮和拨禾从动带轮，在拨禾传动带的外侧上均布设置拨禾指24。左拨禾传动总成和右拨禾传动总成分别位于分禾条8的下方左右两侧并位于割刀机构的上方，左拨禾传动总成和右拨禾传动总成形成前侧张开的入口通道，左拨禾传动总成和右拨禾传动总成上的拨禾指24在水平高度和/或前后位置错开设置(即一拨禾传动总成上的拨禾指24高于另一拨禾传动总成上的拨禾指24，且一拨禾传动总成上的拨禾指24与另一拨禾传动总成上的拨禾指24在前后位置可错开设置)，左拨禾传动总成和右拨禾传动总成上的拨禾带盒22相对应侧的盒壁上设置一供拨禾指伸出的通道口25，拨禾指24伸出对应的拨禾带盒22上的通道口25，左拨禾传动总成和右拨禾传动总成上的对应的拨禾指24在垂直方向上交叉。分禾条8靠近底部设置一分流板36，分流板36在水平高度上高于左拨禾传动总成和右拨禾传动总成。
挡板21设置在左侧的拨禾带盒22和右侧的拨禾带盒22的后侧，挡板21与一拨禾带盒连接，挡板21与另一拨禾带盒之间形成一拨禾输送通道26，拨禾输送通道26位于夹持输送链机构的正下方。在本实施例中，左侧的拨禾带盒22和右侧的拨禾带盒22均由上拨禾带盒和下拨禾带盒构成，左侧的上拨禾带盒和下拨禾带盒的右侧之间形成通道口25，右侧的上拨禾带盒和下拨禾带盒的左侧之间形成通道口25，挡板21的前侧右部与右侧的拨禾带盒22固定连接，挡板21的前侧左部与左侧的拨禾带盒22之间形成拨禾输送通道26。
左拨禾传动总成和右拨禾传动总成上的拨禾指24的旋转方向不在同一个平面上、且前后形成错位，左侧的和右侧的拨禾指24的运行轨迹在平面上不相 交。在运行轨迹的垂直方向上，左侧的和右侧的拨禾指24构成运行的封闭空间。在拨动秸秆运行时，左拨禾传动总成和右拨禾传动总成形成前侧张开的入口通道将拨动秸秆向中集中，后面的挡板21的直边构成秸秆拨动运行的轨迹(即拨禾输送通道26)，起排出秸秆的作用，此时，双向夹持链条27已夹持着秸秆可完成排草全过程。
扶禾机构包括左扶禾机构和右扶禾机构，左扶禾机构和右扶禾机构均包括扶禾板2以及设置在扶禾板2内的环形传输带3、主动轮4、从动轮5、左折弯导向轮Ⅰ、右折弯导向轮Ⅰ6、左折弯导向轮Ⅱ和右折弯导向轮Ⅱ10。扶禾板2由上扶禾板和下扶禾板组成。上扶禾板的上表面和下扶禾板的下表面分别拉伸形成一凹槽39，上扶禾板和下扶禾板上的凹槽39的两侧外形成扶禾指7的运行轨迹，上扶禾板的凹槽与下扶禾板的凹槽贴合形成安装结合部(即上扶禾板和下扶禾板通过凹槽上设置螺栓孔和螺栓连接)，上扶禾板的凹槽39上安装装饰小板40，装饰小板40遮住上扶禾板上的凹槽39。
扶禾板2上部向后弯折，左折弯导向轮Ⅰ和右折弯导向轮Ⅰ6安装在扶禾板2折弯部位下的两侧(即安装在下扶禾板折弯部位下的两侧)，左折弯导向轮Ⅱ和右折弯导向轮Ⅱ10安装在扶禾板2折弯部位下的两侧并位于左折弯导向轮Ⅰ和右折弯导向轮Ⅰ6的上方后侧。下扶禾板22的顶部固定在支撑板17上，下扶禾板的底部通过支撑板41支撑在割刀架15上，支撑板41的上端固定在下扶禾板的底部，支撑板41的下端固定在割刀架15上。主动轮4安装在扶禾板2的顶部，从动轮5安装在扶禾板2的底部，主动轮4和从动轮5的轴线与左折弯导向轮Ⅰ和左折弯导向轮Ⅱ的轴线垂直。环形传输带3依次绕过主动轮4、左折弯导向轮Ⅱ、左折弯导向轮Ⅰ、从动轮5、右折弯导向轮Ⅰ6和右折弯导向轮Ⅱ10，环形传输带3的外圆周上均布固定设有多个扶禾指7。
左扶禾机构和右扶禾机构分别位于分禾条8的两侧，左侧的扶禾板2和右侧的扶禾板2相对应的侧壁分别设置通槽9，左侧的扶禾指7和右侧的扶禾指7伸出对应扶禾板2的通槽9。在本实施例中，左侧的上扶禾板和下扶禾板的右 侧之间形成通槽9，右侧的上扶禾板和下扶禾板的左侧之间形成通槽9。在左侧的上扶禾板上的右侧设置伸向左扶禾机构和右扶禾机构的中间的左入口挡板42，在右侧的上扶禾板上的左侧设置伸向左扶禾机构和右扶禾机构的中间的右入口挡板43。
环形传输带3的外圆周上均布固定设置安装座44，扶禾指7的一端设置安装孔，安装座44插入扶禾指7的安装孔内，如图8所示。安装座44上和扶禾指7设置安装孔的一端对应设置锁销孔45，锁紧销插入扶禾指7设置安装孔的一端上的锁销孔45和安装座44上的锁销孔45中。扶禾指7加长，扶禾指7设置安装孔的一端的上侧和下侧具有导向块46，扶禾指上的导向块46与运行方向对应的侧端面和该扶禾指与运行方向对应的侧端面在同一平面上,扶禾指上的导向块46与运行方向对应的侧端面和该导向块46的另一侧端面相对安装座44为对称面，导向块46没有延伸尾部,扶禾指7的四周倒角。环形传输带3采用高强度纤维线芯带棱面的传动带。左扶禾机构或者右扶禾机构都是独立可完成单行收割扶禾作业的模块化单元,以此模块可构成单行及多行的扶禾机构总成。
夹持输送链机构包括双向夹持链条27、折弯导向板28、压条29和压草板30。双向夹持链条27的链板上设置竖向链齿31，双向夹持链条27靠近扶禾指7一侧链板的外侧设置横向链齿32，横向链齿32设置在双向夹持链条27靠近扶禾指7一侧链板外侧的底部。折弯导向板28位于双向夹持链条27的上方，折弯导向板28的前侧与扶禾板2固定连接，折弯导向板28的后侧与压草板30固定连接，折弯导向板28的右侧由引导面33和折弯面34组成(即折弯导向板28靠近左扶禾机构和右扶禾机构之间的中部向外凸出形成光滑过渡的锥形导向面)，折弯导向板28的引导面33和折弯面34有利于作物的穗部顺利引入压草板30的下方。压条29的一端固定在折弯导向板28或扶禾板2上，压条29的另一端沿横向链齿32的下方水平伸出。
脱粒滚筒1安装在集粮筒14内，集粮筒14的底部向下形成弧形槽18，在左侧护板11上设置与集粮筒14的弧形槽18对接的搅龙筒19，弧形槽18和搅 龙筒19内均安装绞笼。中间隔板13的右侧设置一引流板35，如图9所示，引流板35靠近中间隔板13的一侧比远离中间隔板13的一侧低，脱粒过程中，落入引流板35上的粮食会沿着引流板35的倾斜表面滚入集粮筒14内，进而进入弧形槽18内由绞笼排出。
脱粒滚筒1的轴线与集粮筒14的板面平行，脱粒滚筒1靠近端部圆周上均布多个扇形叶片20，多个扇形叶片在轴向(指脱粒滚筒1的轴向)上的投影形成封闭，相邻两个扇形叶片在径向(指脱粒滚筒1的径向)上形成开口，该开口便于排出脱粒后的秸秆蕙部以及杂物。脱粒后的秸秆，从两扇形叶片20之间的螺旋形开口处被双向夹持链条27带出，能起到限制脱粒后的粮食溢出的作用。
收割机在向前行驶的过程中，分禾板16和分禾条8将作物引入对应的左扶禾机构和右扶禾机构之间，扶禾指7作环形运动，从下向上将作物梳理整齐。扶禾指7运行到折弯导向轮处时，便改变方向向后运动，作物的穗部在折弯导向板28的导向下以及在向后运动的扶禾指7和横向链齿32的作用下，作物的穗部进入运行中的双向夹持链条27，作物秸秆被折弯后随链条的运行进入脱粒滚筒1脱粒。以此同时，左拨禾传动总成和右拨禾传动总成上的拨禾指24带动作物的茎秆并结合割刀机构将其割断的作物茎秆传递到拨禾输送通道26，脱粒后的作物通过双向夹持链条27和拨禾输送通道26排出。
图1中，47为扶禾角齿变速箱，48为传动轴外护壳，49为扶禾传动变速箱，扶禾角齿变速箱47和扶禾传动变速箱49均用于驱动扶禾机构的主动轮4。图4和图5中，50为扶禾、割刀、拨禾、夹持输送链动力分配变速箱，51为割刀动力变速箱，52为拨禾动力变速箱，53为拨禾角齿变速箱，54为提升绞笼角齿变速箱，55为提升绞笼连接变速箱，56为集粮绞笼、脱粒滚筒变速箱。扶禾、割刀、拨禾、夹持输送链动力分配变速箱50将动力分配给割刀动力变速箱51、拨禾动力变速箱52和夹持输送链。图6中，57为提升绞笼，58为脱粒夹持链张紧调节轮，59为夹持链下部外护板，脱粒夹持链张紧调节轮58用于调节双向夹持链条27的松紧程度。
扶禾、割刀、拨禾、夹持输送链动力分配变速箱50的输出轴分别与拨禾机构、扶禾机构、夹持输送链机构、割刀机构的变速箱连接，扶禾、割刀、拨禾、夹持输送链动力分配变速箱50的输入轴与经行驶调速控制后的关联动力输出轴连接，使割刀运行机构、脱粒夹持输送链运行机构与行驶运行机构相连接，割刀的每一个动作的切割量是相对恒定，夹持输送链运行的承载量也相对恒定，收割机工作运行将更精确和顺畅。
扶禾指工作运行轨迹与收割机行驶距离以及收割植株的关系如图10所示；i扶≈A/sinQ，其中i扶是环形传输带的运行速度，Q是扶禾板与地面之间的夹角，A是双向夹持链条对应植株折弯点与地面之间的垂直距离。I运≈C/cosQ，I运是收割机的作业速度，C是扶禾板和地面的交点与折弯点在地面上的投影点之间的距离。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
