请参阅图1、图2、图3以及图5，本公开实施例提供的松土器组件，包括松土器装置100、挂载件110、承载件120以及承力组件。
松土器装置100包括车体连接部102和松土器连接部104，车体连接 部102与松土器连接部104可以是可拆卸的独立结构，也可以是一体成型结构。作业机械向前运动时，松土器装置100可以松动地基表层土。
为了使松土器装置100与车体200紧密连接，车体连接部102形成有与车体200贴合的连接面，连接面的形状尺寸与车体200的轮廓相适应，连接面可以增加松土器装置100安装在车体200上的稳定性。
在一些实施例中，车体连接部102与松土器连接部104之间具有夹角，车体连接部102与松土器连接部104的其中一个连接于车体200的背面，另一个连接于车体200的底面，使松土器装置100与车体200稳定连接。
为了使挂载件110与松土器装置100的车体连接部102稳定连接，挂载件110焊接于车体连接部102，焊接结构的强度较大，可以承受来自松土器装置100的水平荷载。
在一些实施例中，松土器组件还包括底座112，底座112设置于挂载件110靠近松土器装置100的一端，且底座112与挂载件110一体成型，底座112固定连接于车体连接部102。
底座112与挂载件110形成“L”型构件，底座112的面积较大，焊接于车体连接部102时，稳定性较强，增加了挂载件110承受水平荷载的能力。
在另一些实施例中，松土器装置100还包括加强部106，加强部106连接于车体连接部102和松土器连接部104。
车体连接部102与松土器连接部104之间具有夹角，在松土器连接部104承受来自松土器300的水平荷载时，加强部106可以避免松土器连接部104在外部荷载作用下出现变形，提升了松土器装置100的结构稳定性。为了避免出现局部应力集中的情况，加强部106还形成有倒角。
承载件120被构造成固定在车体200上，在松土器装置100贴紧车体200时，承载件120和挂载件110沿车体200的前后方向设置，承载件120用于传递来自挂载件110的水平工作荷载。
车体200的车头方向为前，车尾为后，沿车体200的前后方向，承载件120位于挂载件110的前方，承力组件卡接于挂载件110和承载件120，承力组件可以将挂载件110上的工作荷载传递至承载件120，来自松土器装置100的工作荷载被传递至车体200。在松土器装置100与车体200之 间设置有安装螺栓150时，安装螺栓150起到定位支撑作用，减少了安装螺栓150承担的水平方向的荷载，降低了安装螺栓150出现磨损断裂的情况，松土器装置100与车体200之间不容易松动开裂，稳定性较好。
本公开实施例提供的松土器组件，不需要设置横梁或者连杆等结构，体积较小，方便推广使用。
根据本公开提供的实施例，承力组件连接于挂载件110和承载件120，可以传递挂载件110和承载件120之间的水平工作荷载。
在一些实施例中，挂载件110和承载件120均为销轴结构，承力组件包括连接板，连接板上形成有两组安装孔，安装孔的规格与挂载件110和承载件120的尺寸相适应，挂载件110和承载件120一一对应插接在两个安装孔内。
连接板不仅可以维持挂载件110和承载件120之间的距离，还可以传递挂载件110和承载件120之间的水平荷载，减少安装螺栓150承担的水平方向的荷载。
挂载件110和承载件120均为棱柱结构且安装孔为多边形结构时，连接板的稳定性较好，不会出现松动的情况。
在一些实施例中，承力组件包括连接板，连接板转动连接于挂载件110和承载件120的其中一个，连接板的一侧向内凹陷形成有卡槽。转动连接板，可以使卡槽卡接于挂载件110和承载件120中的另外一个。
在一些实施例中，承力组件包括连接件130，连接件130的底侧向内凹陷形成安装槽132，挂载件110和承载件120卡接于连接件130的安装槽132内。
连接件130不仅可以限制挂载件110与承载件120的运动，还可以将挂载件110的工作荷载传递至承载件120，减少了安装螺栓150承担的水平方向的荷载，避免了安装螺栓150的磨损破坏。
挂载件110与承载件120的截面形状可以根据需要设置，安装槽132的形状与挂载件110和承载件120的外部轮廓相适应，且挂载件110和承载件120的横截面面积之和与安装槽132的横截面面积相匹配。
在一些实施例中，为了增加挂载件110与承载件120传递荷载的稳定 性，连接件130的数量可以为多个，多个连接件130沿车体的前后方向并列设置。
根据本公开的实施例，连接件130卡接于挂载件110和承载件120，可以传递挂载件110和承载件120之间的荷载，增加连接件130与挂载件110和承载件120之间的摩擦力，有助于提升连接件130的位置稳定性和防脱性能。
在一些实施例中，安装槽132包括槽底1322、槽口1324以及相对设置的第一槽壁1326和第二槽壁1328，第一槽壁1326贴合于挂载件110，第二槽壁1328贴合于承载件120。
第二槽壁1328具有第一斜面1329，承载件120具有与第一斜面1329配合的第二斜面122，第一斜面1329沿着槽底1322至槽口1324的方向，向挂载件110所在的方向倾斜设置。
承载件120可以为锲形结构，且锲形结构靠近槽底1322的部位尺寸较大，靠近槽口1324的部位尺寸较小，锲形结构可以防止连接件130沿着槽口1324脱落，提升了连接结构的稳定性。
当车体200与松土器装置100之间存在水平荷载时，为了防止连接件130相对于挂载件110和承载件120滑动，需要确保连接件130和承载件120之间具有足够的摩擦力，即摩擦力大于滑动分力，挂载件110和承载件120之间形成自锁效应。
请参阅图2，假设承载件120的第二斜面122与水平方向的夹角为R，连接件130受到竖直方向的作用力为F，连接件130与承载件120的相邻接触面之间的摩擦系数为f，则满足以下关系：
F*cosR*f≥F*sinR，即f≥tanR。
当摩擦系数与夹角R存在以上关系时，连接件130与承载件120之间形成自锁效应，无论荷载多大，连接件130与承载件120之间都不会发生相对滑动，松土器组件的稳定性较高。
在一些实施例中，承力组件还包括顶出部件134，顶出部件134活动连接于松土器装置100，用于调节所述连接件的位置，使得第一槽壁1326紧贴于挂载件110，且使得第二槽壁1328紧贴于承载件120。
当挂载件110和承载件120的横截面面积之和小于安装槽132的横截面面积时，挂载件110和承载件120之间具有间隙。安装槽132的尺寸稍大于挂载件110和承载件120，有助于挂载件110和承载件120插设在安装槽132内，有助于松土器组件与车体200的装配连接。
在松土器装置100和连接件130之间设置顶出部件134，顶出部件134可以适当改变连接件130的位置，使第一槽壁1326紧贴于挂载件110，且使第二槽壁1328紧贴于承载件120。
在另一些实施例中，可以沿侧向将承载件120插设在安装槽132内，然后再将承载件120焊接在车体200上，此时安装槽132的横截面面积与挂载件110或者承载件120的横截面面积之和相同。
根据本公开的实施例，顶出部件134可以调整连接件130的位置，使挂载件110、承载件120和连接件130紧密卡接。
在一些实施例中，松土器装置100的车体连接部102形成有螺孔，顶出部件134包括螺杆，螺杆转动连接于车体连接部102的螺孔，螺杆的端部抵接于槽口1324靠近承载件120的一侧的端面。
槽口1324的两侧形成有两个端面，其中一个靠近挂载件110，另一个靠近承载件120(也即远离挂载件110)，安装槽132的尺寸稍大于挂载件110和承载件120，更便于挂载件110和承载件120安装于安装槽132内。因第二槽壁1328贴合于承载件120，且承载件120的第二斜面122与第二槽壁1328的第一斜面1329配合，在螺杆的端部抵接于槽口1324靠近承载件120的一侧的端面，且施加向上作用力时，连接件130沿斜面向上移动，使得第二槽壁1328紧贴于承载件120，且连接件130相对于挂载件110发生顺时针方向的转动，可以使连接件130的第一槽壁1326紧贴于挂载件110，如此，连接件130可以将挂载件110上的工作荷载传递至承载件120，因此，来自松土器装置100的工作荷载可以传递至车体200，减少了安装螺栓150承担的水平方向的荷载。
螺杆相对于车体连接部102转动时，螺杆受到车体连接部102和连接件130之间的轴向力，螺栓在轴向力作用下强度较大，不会受到磨损，稳定性高且使用寿命长。
根据本公开的实施例，挂载件110、承载件120以及连接件130将相关技术中螺杆承受的剪力转换为轴向力，改变了螺杆的受力方向，减少了螺杆的磨损。
在一些实施例中，顶出部件134还包括定位螺母136，定位螺母136转动连接于螺杆且设置在松土器装置100与连接件130之间。
定位螺母136可以固定螺杆的位置，在螺杆向上转动且抵接于连接件130时，转动定位螺母136使其固定螺杆的位置，避免螺杆相对于松土器装置100向下转动，可以使连接件130维持与松土器装置100之间的位置关系，挂载件110、承载件120与连接件130的卡接更为稳定，更有利于连接件130将挂载件110上的工作荷载传递至承载件120。
调节螺杆相对于车体连接部102的伸出长度，可以调节连接件130的偏转角度，使挂载件110和承载件120紧密贴合。转动定位螺母136，可以使螺杆与车体连接部102之间锁紧，螺杆不会相对于车体连接部102转动，可以避免螺杆因振动而出现松动的情况，连接件130的偏转角度也不发生变化，可以使挂载件110、承载件20以及连接件130之间始终处于锁紧状态。
在一些实施例中，还可以设置其它锁紧结构以对螺杆进行约束，避免螺杆在长期振动作用下出现松动。
根据本公开的实施例，第二槽壁1328具有第一斜面1329，承载件120具有与第一斜面1329配合的第二斜面122，第一斜面1329沿槽底1322至槽口1324的方向，向挂载件110所在的方向倾斜，倾斜设置的第二槽壁1328会增加与连接件130之间的摩擦力。
在一些实施例中，如图5所示，第一槽壁1326具有第三斜面1327，挂载件110具有与第三斜面1327配合的第四斜面114，第一槽壁1326的第三斜面1327沿槽底1322至槽口1324的方向，向承载件120所在的方向倾斜，倾斜设置的第一槽壁1326会增加与连接件130之间的摩擦力。
挂载件110和承载件120可以均为锲形结构，挂载件110和承载件120相互远离的侧面均为斜面，且安装槽132的第一槽壁1326和第二槽壁1328均倾斜设置，此时，挂载件110、承载件120和连接件130之间的摩擦力 增加，松土器组件的稳定性较高。
第一槽壁1326的倾斜角度与摩擦系数同样满足自锁效应关系，可以确保挂载件110和连接件130之间稳定连接。
根据本公开的实施例，挂载件110和承载件120位于连接件130的安装槽132内，安装槽132可以限制挂载件110和承载件120的移动。
在一些实施例中，松土器组件还包括防脱组件140，防脱组件140可拆卸地连接于松土器装置100或车体200，且设置于承载件120远离车体200的一侧，防脱组件140可以限制承力组件沿远离车体200的方向移动。
在承载件120为锲形结构时，第一槽壁1326贴合于挂载件110，第二槽壁1328贴合于承载件120，连接件130不会沿着槽口1324处脱离挂载件110和承载件120。
在松土器装置100或者车体200上安装防脱组件140，防脱组件140和车体200可以限制承力组件的位置，避免承力组件沿远离车体的方向移动脱落，提升了松土器组件的稳定性。
在一些实施例中，防脱组件140包括限位盖板142和固定螺栓144，限位盖板142通过固定螺栓144安装在松土器装置100或者车体200上。
在其它一些实施例中，可以在连接件130和挂载件110之间或者连接件130和承载件120之间设置限位组件，例如销钉、螺栓等结构，将连接件130固定在挂载件110或者承载件120上，也可以起到防脱的效果。
根据本公开实施例提供的作业机械，包括车体200和本公开实施例提供的松土器组件，松土器组件连接于车体200的底部或者尾部。作业机械可以为平地机等具有松土器的机械设备。
在作业机械中，承力组件连接于挂载件110和承载件120，承力组件可以将挂载件110上的工作荷载传递至承载件120，来自松土器装置100的工作荷载被传递至车体200。如此，在松土器装置100与车体200之间设置有安装螺栓150时，安装螺栓150起到定位支撑作用，减少了安装螺栓150承担的水平方向的荷载，降低了安装螺栓150出现磨损断裂的情况，松土器装置100与车体200之间不容易松动开裂，稳定性较好。
本公开实施例提供的松土器组件，不需要设置横梁或者连杆等结构， 体积较小，方便推广使用。
根据本公开实施例提供的松土器组件和作业机械，松土器组件包括松土器装置100、挂载件110、承载件120以及承力组件，挂载件110连接于松土器装置100，承载件120被构造成固定设置在车体200上，承载件120和挂载件110沿着车体200的前后方向设置，承力组件卡接于挂载件110和承载件120，承力组件可以传递挂载件110上的工作荷载到承载件120上。通过螺栓进行传递的松土器装置100和车体200之间的工作荷载将会减少，减少了螺栓的磨损，松土器装置100与车体200之间不会松动开裂，稳定性较好，且松土器组件的体积较小，方便推广使用。
以上仅为本公开的优选实施例而已，并不用于限制本公开，对于本领域的技术人员来说，本公开可以有各种更改和变形。凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
