Description

一种切碎器 技术领域
本申请涉及破碎装置技术领域，具体涉及一种切碎器。
背景技术
将联合收割机收割后的谷草切碎抛洒还田是一项既能防止焚烧秸秆污染空气又能作为有机肥料肥沃土地的符合环保要求的重要措施，为了达到这一目的，现有的联合收割机均已配备了破碎装置。
联合收割机收割作物后留下的秸秆若长度过长，农户一般采用焚烧秸秆的方法清理田地，焚烧秸秆时产生大量的烟尘严重污染空气，燃烧排放的二氧化碳增大了大气中二氧化碳的含量，加剧了温室效应；与减少大气中二氧化碳排放的环保要求背道而驰。
为了避免出现前述状况，现有的联合收割机采用低茬收割作物，降低了农田里留下的秸秆高度，使其无法进行焚烧。同时，联合收割机割下的秸秆长度较长，必须经过联合收割机充分切碎后铺撒在农田里，在拖拉机翻地时，将农田里留下的秸秆和碎草翻入土中充作肥料，才能从根本上杜绝焚烧秸秆。现有的联合收割机切草器沿动刀辊径向采用四个一组的刀片组合交叉成十字形排列，刀片组合在动刀辊轴向间隔排列六排，每组刀片组合共有4个刀片，共计有24个刀片，通过加大切草器主轴转速来提高其碎草性能，这种方法虽然达到了碎草效果，但消耗了联合收割机的很大一部分功率。并且提高转速后还需增加对切草器的动平衡要求，直接加大了切 草器的制造成本。
发明内容
因此，本申请要解决的技术问题在于克服现有技术中的破碎装置分撒效率低。
为此，本申请提出一种切碎器，包括：
左侧壁和右侧壁；
动刀辊，设置在所述左侧壁和所述右侧壁之间；
多个动刀片，呈螺旋状排列分布并可拆卸地安装在所述动刀辊上；任一所述动刀片平行于所述动刀辊的横截面；
定刀座，设置在所述动刀辊斜下方；
多个定刀片，同向且均匀间隔设置在所述定刀座上；所述动刀辊受驱动旋转时，所述动刀辊带动所述动刀片旋转经过所述定刀片之间的间隙。
所有所述动刀片在所述动刀辊横截面所在的平面上的正投影围成闭合环。
还包括：

沿圆柱形的所述动刀辊的母线展开的方形结构中，在长度方向上，多个所述动刀座成排设置；在宽度方向上，所述动刀座成多排设置。
在宽度方向上，相邻排的所述动刀座同向倾斜设置。
相邻排中的所述动刀座在长度方向上一一间隔设置。
还包括防缠圈；所述防缠圈包括：
至少两个圈板，分别呈圆弧形结构；所有所述圈板首尾相接围成圆环 状的隔离区；
至少两个卡板，固定在相接的两个圈板中的其一圈板上，且与该圈板之间形成插槽；另一所述圈板适于插接固定在所述插槽中。
任一所述圈板包括底板和侧板；所述底板为平板，呈圆弧形弯曲设置；所述侧板为曲面板，沿所述底板外圈边缘设置。

实施例1
本实施例提供一种切碎器，如图1所示，包括收割机上排草通道的左侧壁10r和右侧壁11r，为便于清晰的展示其他结构，左侧壁10r和右侧壁11r在图1中仅以部分示出。动刀辊1r设置在左侧壁10r和右侧壁11r之间。动刀辊1r为圆柱形辊。多个动刀片2r呈螺旋状排列分布并可拆卸地安装在动刀辊1r上，任一动刀片2r平行于动刀辊1r的横截面。
如图3所示，多个动刀座5r焊接固定在动刀辊1r上，动刀片2r一一对应并固定安装在动刀座5r内。每个动刀座5r呈匚型结构，本实施例中，动刀片2r栓接固定在动刀座5r的匚型安装腔内。
如图4所示，将动刀辊1r沿其圆柱形的其中一条母线展开平铺后的方形结构中，在长度方向上，多个动刀座5r成排并倾斜设置，如图4所示，六个动刀座5r组成一排，且从左上的第一个动刀座5r依次向右下倾斜间隔排布。在宽度方向上，动刀座5r呈多排设置，如图4所示，本实施例中，动刀座5r自上而下形成四排，四排动刀座5r同向倾斜设置。且相邻排中的动刀座5r在长度方向上一一间隔设置，即第一排动刀座5r与第二排动 刀座5r错位设置，第一排动刀座5r与第三排动刀座5r位置相同，形成逐排交叉，在动刀辊1r上的分布状态如图5所示，使得所有动刀座5r在动刀辊1r横截面所在的平面上的正投影呈闭合环型，如图6所示，动刀座5r内均安装动刀片2r后，使得动刀片2r同样能够在动刀辊1r的横截面所在的平面上围成闭合环。
定刀座3r设置在动刀辊1r的斜下方，如图2所示，多个定刀片4r同向且均匀间隔设置在定刀座3r上，相邻两个定刀片4r之间对应通过一列动刀片2r，例如图4中，第一列动刀片2r为第一排和第三排中左数第一个动刀座5r上的动刀片2r，第二列动刀片2r为第二排和第四排中左数第一个动刀座5r上的动刀片2r，以此类推。
动刀辊1r受驱动旋转时，动刀辊1r带动动刀片2r旋转经过定刀片4r之间的间隙。将动刀片2r在动刀辊1r的辊面上呈螺旋状排列分布，动刀辊1r处于任一旋转位置上时，能够保证均有动刀片2r能经过定刀片4r之间的间隙，即能够始终保持动刀片2r与定刀片4r之间的切削状态，在动刀辊1r常规转速下，仍然提高了切碎效率，降低了为提高转速带来的动力输出成本，同时避免了提高转速导致破坏动平衡带来的安全隐患。
如图7所示，防缠圈K套设在动刀辊1r两端的轴承座上并固定在左侧壁10r和右侧壁11r上。如图7所示，每一个防缠圈K包括至少两个圈板1k和至少两个卡板2k。圈板1k分别呈圆弧形结构，所有圈板1k首尾相接围成圆环状的隔离区。至少两个卡板2k，固定在相接的两个圈板1k中的其一圈板1k上，且与该圈板1k之间形成插槽3k；另一圈板1k适于插接固定在该插槽3k中。
本实施例中，如图7所示，任一圈板1k包括底板11k和侧板12k，底板11k为平板，呈圆弧形弯曲设置，侧板12k为曲面板，沿底板11k的外圈边缘设置，本实施例中，底板11k和侧板12k一体成型。
本实施例中，圈板1k设置两个，两个圈板1k均呈半圆弧状，其一圈板1k外壁面贴合在另一圈板1k的内壁面上，并在叠加的两个底板11k上打孔，通过螺栓固定连接两个圈板1k。底板11k上还开设若干装配孔5k，装配孔5k与常规螺栓尺寸相匹配，螺栓穿过装配孔5k将防缠圈安装固定在左侧壁10r和右侧壁11r上。当然，圈板1k也可以为三个或四个等，顺序依次首尾相接，围成圆环状隔离区即可，圈板1k的具体数量视具体情况而定。
本实施例中，任一圈板1k的侧板12k垂直底板11k设置，卡板2k呈L形折弯，L形短边焊接固定在其一侧板12k的外壁面上，并位于该侧板12k的两端，L形长边与该侧板12k之间平行设置，卡板2k与侧板12k之间形成插槽3k，另一侧板12k的两端对应插接在该插槽3k中。
再如图7所示，底板11k上还开设至少一个排障口，用于观察或者从中伸入其他设备，本实施例中，排障口为由圆弧形的底板11k内圈边缘朝向外圈边缘凹陷成型的排障槽4k，排障槽4k整体呈等腰梯形，且槽口的宽度大于槽底的宽度。槽口位于底板11k的内圈上，防缠圈的底板11k围成的孔用于套设固定在轴承座上，因此，槽口扣合在轴承座表面，槽口尺寸大，更便于观察内部情况。本实施例中，每个圈板1k的底板11k上各设置两个排障槽4k，四个排障槽4k在圆周上均匀间隔设置。
通过圈板1k围成圆环状隔离区，适于套设固定在驱动转轴上，并阻挡在间隙中，避免杂草或秸秆缠绕在驱动转轴上。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予 以穷举。而由此所引伸出的显而易见的变化或变动仍处于本申请的保护范围之中。
