Description

固定组件及固定装置 技术领域
本发明涉及新能源材料回收利用的技术领域，特别是涉及一种固定组件及固定装置。
背景技术
在废旧电池回收以后，需要经过拆解、烘干、热解及粉碎筛选等操作，然后使用硫酸来酸浸，以去除电池粉中的铜铁铝等杂质，然后才能进行后续的工序。目前的电池粉一般使用吨袋进行包装和运输，在吨袋通过周转箱运输到指定的地点后，需要先将吨袋底部做简单的固定然后再倒料防止吨袋掉入料箱内。然而，在吨袋进行固定时，由于吨袋的重量较重，且吨袋置于周转箱内四周的空间较为紧凑，通常只能够固定吨袋上端的四角或者边缘，以便对吨袋进行倒料操作，使吨袋存在定位难度较高的问题。
发明内容
本发明的目的是克服现有技术中的不足之处，提供一种方便定位吨袋的固定组件及固定装置。
本发明的目的是通过以下技术方案来实现的：
一种固定组件，包括：
连接套；
尖刺件，所述尖刺件与所述连接套转动连接；以及
弹性件，所述弹性件的一端连接于所述连接套，所述弹性件的另一端连接于所述尖刺件，所述弹性件至少螺旋环绕抵接于所述尖刺件的外周壁上，且所述弹性件用于在所述尖刺件沿与所述弹性件的螺旋环绕方向相反的方向相对于所述连接套转动时产生弹性形变，所述弹性形变的方向与所述尖刺件的轴向延伸方向存在夹角，以形成螺旋外凸弹性结构。
一种固定装置，包括周转箱和上述任一实施例所述的固定组件，所述周转箱开设有相连通的容置槽和安装孔，所述连接套位于所述安装孔内并与所述周转箱固定连接，所述尖刺件和所述弹性件均位于所述容置槽内，且所述尖刺件的一端凸出于所述周转箱的外侧。
与现有技术相比，本发明至少具有以下优点：
1)本发明的固定组件，连接套可以固定安装于安装位置，如连接套可以固定安装于周转箱的放置槽的内壁，由于尖刺件与连接套转动连接，且弹性件的一端连接于连接套，弹性件的另一端连接于尖刺件，弹性件至少螺旋环绕于尖刺件的外周壁上，在吨袋放置于周转箱内的放置槽内，并使尖刺件刺穿并插入吨袋的面层时，使尖刺件沿与弹性件的螺旋环绕方向相反的方向相对于所述连接套转动，又由于弹性件用于在尖刺件沿与弹性件的螺旋环绕方向相反的方向相对于连接套转动时产生弹性形变，弹性形变的方向与尖刺件的轴向延伸方向存在 夹角，使弹性件外弹并形成往尖刺件的外周壁向外张开的螺旋外凸弹性结构，起到对吨袋的内壁进行弹压和固定作用，如此起到类似于“钉帽”的固定限位作用，如此实现对吨袋起到较好的固定作用，即使吨袋较好地固定定位于周转箱内，以便对吨袋进一步地倒料操作，实现吨袋的固定定位的整个过程方便快捷，解决了吨袋定位难度较高的问题；2)本发明的固定组件，当不需要固定吨袋时，仅需使尖刺件沿与弹性件的螺旋环绕方向相同的方向相对于连接套转动，即可使弹性件自动复位并旋转收紧环绕于尖刺件的外周壁上，即螺旋外凸弹性结构内缩并紧贴于尖刺件的外周壁表面，亦即是弹性件螺旋环绕抵接于所述尖刺件的外周壁上，此时尖刺件能够从吨袋的面层快速拔出，实现不用固定定位时可以马上解除固定的状态，同时避免了吨袋的结构因固定定位而遭受破坏的问题，实现吨袋循环使用；3)本发明的固定组件，在尖刺件刺穿并插入吨袋的面层时，使尖刺件相对于连接套正、反方向转动，即可实现固定组件对吨袋进行固定定位与解除固定定位的两种不同状态的快速切换，大大提高了固定组件的使用方便性及定位效率。

同时参见图3，在其中一个实施例中，固定组件200包括连接套210、尖刺件220以及弹性件230。其中，连接套210位于安装孔104内并与周转箱100固定连接。尖刺件220与连接套210转动连接。弹性件230的一端连接于连接套210，弹性件230的另一端连接于尖刺件220。弹性件230至少螺旋环绕抵接于尖刺件220的外周壁上，即弹性件230沿自旋方向至少螺旋环绕抵接于尖刺件220的外周壁上。可以理解，在其中一个实施例中，在弹性件230连接于尖刺件220及连接套210，且弹性件230未发生形变时，弹性件230至少螺旋环绕抵接于尖刺件220的外周壁上，即弹性件230至少螺旋紧密环绕并抵接于尖刺件220的外周壁上。
如图4及图5所示，弹性件230用于在尖刺件220沿与弹性件230的螺旋环绕方向相反的方向相对于连接套210转动时产生弹性形变，且弹性形变的方向与尖刺件220的轴向延伸方向存在夹角，即弹性形变的方向与尖刺件220的轴向延伸方向不平行，以形成螺旋外凸弹性结构，使螺旋外凸弹性结构对吨袋的内壁进行弹压和固定作用，即使螺旋外凸弹性结构对吨袋的内壁产生平行于尖刺件220的轴向的轴向力，如此起到类似于“钉帽”弹性固定限位作用于吨袋，如此实现对吨袋起到较好的固定作用。在本实施例中，所谓的螺旋外凸弹性结构为弹性件230因尖刺件220沿与弹性件230的自旋方向相反方向相对于连接套210转动时而产生弹性形变的结构形状，产生弹性形变的弹性件230螺旋环绕于尖刺件220且呈外弹张开的状态，如图4所示，即产生弹性形变的弹性件230未与尖刺件220的外周壁完全紧密抵接，亦即是产生弹性形变的弹性件230存在局部离开于尖刺件220的外周壁的情形，使弹性件230得到旋转展开，以使螺旋外凸弹性结构对吨袋的内壁进行弹压和固定作用。可以理解， 当尖刺件220沿与弹性件230的自旋方向相同的方向相对于连接套210转动时，弹性件逐渐复位，此时螺旋外凸弹性结构逐渐消失，直至弹性件螺旋环绕抵接于尖刺件的外周壁上，使弹性件紧贴于尖刺件的外周壁上。
如图1及图3所示，在本实施例中，尖刺件220和弹性件230均位于容置槽102内，且尖刺件220的一端凸出于周转箱100的外侧，以便在周转箱100的外侧能够使尖刺件220相对于连接套210转动，提高了固定组件200的使用方便性。在一个实施例中，尖刺件220位于容置槽102内的底部，使尖刺件220能够对吨袋的底部进行刺破定位，由于吨袋的重力作用，使尖刺件220能够较好地对吨袋的底部进行刺破定位。
上述的固定装置10及其固定组件200，连接套210可以固定安装于安装位置，如连接套210可以固定安装于周转箱100的放置槽的内壁，由于尖刺件220与连接套210转动连接，且弹性件230的一端连接于连接套210，弹性件230的另一端连接于尖刺件220，弹性件230至少螺旋环绕于尖刺件220的外周壁上，在吨袋放置于周转箱100内的放置槽内，并使尖刺件220刺穿并插入吨袋的面层时，使尖刺件220沿与弹性件230的螺旋环绕方向相反的方向相对于连接套210转动，又由于弹性件230用于在尖刺件220沿与弹性件230的螺旋环绕方向相反的方向相对于连接套210转动时产生弹性形变，弹性形变的方向与尖刺件220的轴向延伸方向存在夹角，使弹性件230外弹并形成往尖刺件220的外周壁向外张开的螺旋外凸弹性结构，起到对吨袋的内壁进行弹压和固定作用，如此起到类似于“钉帽”的固定限位作用，如此实现对吨袋起到较好的固定作用，即使吨袋较好地固定定位于周转箱100内，以便对吨袋进一步地倒料操作，实现吨袋的固定定位的整个过程方便快捷，解决了吨袋定位难度较高的问题；当不需要固定吨袋时，仅需使尖刺件220沿与弹性件230的螺旋环绕方向相同的方向相对于连接套210转动，即可使弹性件230自动复位并旋转收紧环绕于尖刺件220的外周壁上，即螺旋外凸弹性结构内缩并紧贴于尖刺件220的外周壁表面，亦即是弹性件230螺旋环绕抵接于尖刺件220的外周壁上，此时尖刺件220能够从吨袋的面层快速拔出，实现不用固定定位时可以马上解除固定的状态，同时避免了吨袋的结构因固定定位而遭受破坏的问题，实现吨袋循环使用；本发明的固定组件200，在尖刺件220刺穿并插入吨袋的面层时，使尖刺件220相对于所述连接套210正、反方向转动，即可实现固定组件200对吨袋进行固定定位与解除固定定位的两种不同状态的快速切换，大大提高了固定组件200的使用方便性及定位效率。
如图4所示，在一个实施例中，弹性件230的一部分螺旋环绕抵接于尖刺件220的外周壁上，且弹性件230的另一部分还螺旋环绕抵接于连接套210，使弹性件230在连接于连接套210的端部的邻近部位在连接套210的表面存在环绕抵接的尺寸长度，如此在同等螺旋环绕周长尺寸的条件下，当尖刺件220相对于连接套210转动时，能够切换固定组件200快速固定或解除固定吨袋的状态，即能够形成或消除螺旋外凸弹性结构，亦即是能够实现弹性件230的弹性形变的快速产生或消除。可以理解，在其他实施例中，弹性件230还可以是完全 螺旋环绕抵接于尖刺件220的外周壁上，且弹性件230的一端与连接套210的边缘连接。
在其中一个实施例中，弹性形变的方向与尖刺件220的轴向延伸方向相互垂直，即弹性形变的方向与尖刺件220的径向所在的平面相互平行，如此当尖刺件220沿与弹性件230的螺旋环绕方向相反的方向相对于连接套210转动时，使弹性件230沿尖刺件220的径向产生弹性形变，进而使螺旋外凸弹性结构能够更好地对吨袋的内壁进行弹压和固定作用。可以理解，在其他实施例中，弹性形变的方向不仅限于与尖刺件220的轴向延伸方向相互垂直。例如，弹性形变的方向与尖刺件220的轴向延伸方向之间的夹角大于5°且小于或等于80°。
如图4所示，在其中一个实施例中，弹性件230为弹簧线结构，使弹性件230具有较好的弹性强度，同时使形变后的螺旋外凸弹性结构更好地对吨袋的内壁进行弹压和固定作用。可以理解，在其他实施例中，弹性件230不仅限为弹簧线结构，还可以为卷簧或弹性胶件或其他弹性件230。
如图6所示，在其中一个实施例中，弹性件230的横截面直径从弹性件230的中间到弹性件230的两端递减，使弹性件230产生的弹性形变力更好地压持作用于吨袋，如此使螺旋外凸弹性结构更牢固地对吨袋的内壁进行拉持，进而使形变后的螺旋外凸弹性结构更好地对吨袋的内壁进行弹压和固定作用。
如图5所示，在其中一个实施例中，尖刺件220包括依次连接的尖刺端222、环绕部224和转动连接部226，转动连接部226与连接套210转动连接，弹性件230的一端连接于环绕部224，且弹性件230螺旋环绕抵接于环绕部224的外周壁上，使弹性件230连接于尖刺件220上，且弹性件230螺旋环绕抵接于尖刺件220，同时使尖刺件220转动连接于连接套210。在本实施例中，尖刺端222用于刺穿插入吨袋的面层。进一步地，尖刺端222呈圆锥状结构，使尖刺端222更好地刺穿插入吨袋的面层。
为使尖刺件220能够快速地刺穿插入吨袋，如图1所示，在本实施例中，尖刺件220设于周转箱100的放置槽的内壁的底部，使尖刺件220在吨袋放置于周转箱100内时能够刺穿插入吨袋底部的面层，如此在吨袋的自身重力的作用下，使尖刺件220能够快速地刺穿插入吨袋。
如图7至图9所示，在其中一个实施例中，环绕部224邻近尖刺端222的端部的外周壁上形成有限位台阶224a，即环绕部224用于螺旋环绕弹性件230的外周壁的直径小于尖刺端222的邻近环绕部224的直径，亦即是，在尖刺件220的环绕部224的外周壁上形成用于容置弹性件230的收容凹槽229。弹性件230的一端连接于限位台阶224a的表面，且弹性件230螺旋环绕抵接并限位于限位台阶224a，即弹性件230螺旋环绕抵接于限位台阶224a的表面，使弹性件230可靠地螺旋环绕抵接于环绕部224，同时使弹性件230可靠地限位于限位台阶224a的一侧，避免弹性件230在随尖刺件220拔出吨袋的过程中脱离于尖刺件220，同时减小了尖刺件220的横截面，也避免了弹性件230因凸出于尖刺件220的外周壁而对尖刺件220刺破或拔出吨袋产生较大的阻力，进而减小了固定组件200刺破或拔出吨袋所受的阻力，如 此便于固定组件200快速刺破或拔出吨袋。可以理解，当尖刺件220未相对于连接套210沿与弹性件230的自旋方向相反的方向转动时，弹性件230呈螺旋状且紧密环绕抵接于环绕部224的外周壁上。当尖刺件220相对于连接套210沿与弹性件230的自旋方向相反的方向转动时，弹性件230产生弹性形变，此时虽然产生弹性形变的弹性件230依然螺旋环绕于尖刺件220，但是弹性件230呈外弹张开的状态，即产生弹性形变的弹性件230未与尖刺件220的外周壁紧密抵接，以使螺旋外凸弹性结构对吨袋的内壁进行弹压和固定作用。
如图7至图9所示，进一步地，转动连接部226的直径小于环绕部224的直径，使弹性件230的两端分别与连接套210和尖刺件220连接，且弹性件230能够更紧密地环绕于尖刺件220的外周壁上，即弹性件230能够平整且紧密环绕抵接于尖刺件220的外周壁上，进而使固定组件200更好地刺破于吨袋并对吨袋进行固定定位。在本实施例中，环绕部224的直径等于连接套210的直径，使弹性件230更平整地螺旋环绕于尖刺件220的外周壁上，同时使弹性件230在环绕部224与连接套210的连接处的螺旋环绕结构更加平整。
如图10所示，进一步地，转动连接部226的外周壁上形成有第一螺纹226a，连接套210的内周壁上形成有第二螺纹211，连接套210套设于转动连接部226并与转动连接部226螺纹连接，使连接套210与转动连接部226的转动连接，且转动连接部226在与连接套210相对转动的过程中能够使尖刺件220在尖刺件220的轴向与连接套210相对移动。弹性件230与尖刺件220连接的部位为第一端，弹性件230与连接套210连接的部位为第二端，当尖刺件220相对于连接套210沿与弹性件230的自旋方向相反的方向转动时，尖刺件220与连接套210相对移动，减小了第一端与第二端之间的距离，如此形成的螺旋外凸弹性结构更加扁平，提高了螺旋外凸弹性结构对吨袋的内壁的轴向作用力，进而使螺旋外凸弹性结构更好地对吨袋的内壁进行弹压和固定作用。在本实施例中，第一螺纹226a和第二螺纹211为相互适配的螺纹连接结构，使转动连接部226与连接套210螺纹连接。进一步地，第一螺纹226a呈螺旋状环绕于转动连接部226的外周壁上，第二螺纹211呈螺旋状环绕于连接套210的内周壁上，使第一螺纹226a与第二螺纹211更好地螺纹连接，同时使尖刺件220与连接套210的轴向连接位置的调节更加灵活，即使第一端与第二端之间的距离的调节更加灵活。
如图9所示，在其中一个实施例中，连接套210套接于尖刺件220并与尖刺件220转动连接，使连接套210与尖刺件220之间的相对转动连接更加平稳。在本实施例中，连接套210套接于转动连接部226的外周壁并与转动连接部226转动连接。进一步地，第一螺纹226a呈螺旋环绕状设于转动连接部226的外周壁，第二螺纹211呈螺旋环绕状设于连接套210的内周壁上，使连接套210与尖刺件220螺纹连接。
为使固定组件200的结构较简单，如图8所示，在其中一个实施例中，弹性件230的两端分别焊接于尖刺件220的外周壁和连接套210的外周壁上，这使弹性件230的两端分别连接于尖刺件220和连接套210上，同时使固定组件200的结构较简单。
然而，由于吨袋的重量较大，在固定装置10反复多次固定吨袋的过程中，弹性件230的 两端受重力的作用容易存在断裂甚至脱离于尖刺件220及连接套210，如此导致固定组件200多次使用后存在报废的问题，使固定组件200的使用寿命较短；此外，受重力的作用，固定组件200的弹性件230容易存在塑性变形，即弹性件230在复位后无法螺旋紧密环绕抵接于尖刺件220的外周壁上，亦即是弹性件230存在局部凸出于尖刺件220的外周壁上，进而使尖刺件220穿刺刺入吨袋过程中所受的阻力较大，使固定组件200固定定位吨袋所需的时间较长，循环反复使用之后，使弹性件230存在的塑性变形更严重，最终导致固定组件200报废无法进一步使用，使固定组件200的使用寿命较短。为提高固定组件200的使用寿命及使用方便性，如图10所示，在另外一个实施例中，弹性件230的两端分别可拆卸连接于尖刺件220的外周壁和连接套210的外周壁上，以便对弹性件230进行定期维护或更换，如此提高了固定组件200的使用寿命及使用方便性。在其中一个实施例中，弹性件230的第一端设有第一弯折部230a，尖刺件220的外周壁上开设有第一插接孔223，第一弯折部插接于第一插接孔223内，使弹性件230可拆卸连接于尖刺件220的外周壁上。弹性件230的第二端设有第二弯折部230b，连接套210的外周壁上开设有第二插接孔213，第二弯折部插接于第二插接孔213内，使弹性件230可拆卸连接于连接套210的外周壁上。为避免第二插接孔213的开设影响连接套210的结构强度的问题，进一步地，连接套210的外周壁上凸设有安装凸台212，第二插接孔213开设于安装凸台212，使连接套210开设有第二插接孔213的位置具有较好的结构强度，避免了第二插接孔213的开设影响连接套210的结构强度的问题。
可以理解，如图11和图12所示，在其他实施例中，弹性件230的两端不仅限于通过插接的方式连接于连接套210和尖刺件220。在其中一个实施例中，弹性件230的第一端和弹性件230的第二端均与尖刺件220的横截面平行。同时参见图13和图14，弹性件230的第一端形成有第一弧形弯钩230c，第一弧形弯钩230c形成有第一固定孔233。弹性件230的第二端形成有第二弧形弯钩230d，第二弧形弯钩230d形成有第二固定孔235。固定组件200还包括第一锁紧件240，尖刺件220的外周壁上开设有第一连接孔225，第一锁紧件240分别穿设于第一固定孔233和第一连接孔225内，使第一锁紧件240将第一端固定连接于尖刺件220，实现弹性件230与尖刺件220可拆卸连接。固定组件200还包括第二锁紧件250，连接套210的外周壁上开设有第二连接孔215，第二锁紧件250分别穿设于第二固定孔235和第二连接孔215内，使第二锁紧件250将第二端固定连接于连接套210，实现弹性件230与连接套210可拆卸连接。在本实施例中，尖刺件220的横截面与尖刺件220的轴向相垂直。第一连接孔225和第二连接孔215均可以为螺纹孔，第一锁紧件240和第二锁紧件250均可以为螺丝或螺钉，使第一锁紧件240和第二锁紧件250的结构均较简单。
为使第一锁紧件240更好地将第一端固定连接于尖刺件220，同时使第二锁紧件250更好地将第二端固定连接于连接套210，如图13所示，进一步地，第一弧形弯钩230c的背离尖刺件220的一面设有第一抵接斜面237，第一锁紧件240与第一弧形弯钩230c抵接的部位设有第一压紧斜面241，第一压紧斜面241与第一抵接斜面237抵接，避免第一锁紧件240 与第一端抵接处存在抵接可靠性较差而晃动的情形，使第一锁紧件240更稳固地将第一端固定连接于尖刺件220。第二弧形弯钩230d的背离连接套210的一面设有第二抵接斜面239，第二锁紧件250与第二弧形弯钩230d抵接的部位设有第二压紧斜面251，第二压紧斜面251与第二抵接斜面239抵接，避免第二锁紧件250与第二端抵接处存在抵接可靠性较差而晃动的情形，使第二锁紧件250更稳固地将第二端固定连接于连接套210。
为使第一锁紧件240更好地抵接压紧于第一端，进一步地，固定组件200还包括第一弹性压紧圈，第一弹性压紧圈套设于第一锁紧件240，且第一弹性压紧圈弹性抵接于第一弧形弯钩230c的内周壁，使第一锁紧件240更好地抵接压紧于第一端。为使第二锁紧件250更好地抵接压紧于第二端，进一步地，固定组件200还包括第二弹性压紧圈，第二弹性压紧圈套设于第二锁紧件250，且第二弹性压紧圈弹性抵接于第二弧形弯钩230d的内周壁，使第二锁紧件250更好地抵接压紧于第二端。在本实施例中，第一弹性压紧圈和第二弹性压紧圈均为弹性硅胶圈。
为避免第一锁紧件240和第二锁紧件250对穿刺于吨袋进行固定定位的过程中产生干涉，导致固定组件200穿刺于吨袋所受的阻力较大的问题，如图13和图14所示，进一步地，第一连接孔225开设于尖刺端222的邻近环绕部224的端面，即第一连接孔225开设于限位台阶224a的内周壁上，使第一锁紧件240将第一端固定连接于尖刺件220时收容于收容凹槽229内。第二连接孔215开设于连接套210邻近尖刺端222的端面，使第二锁紧件250将第二端固定连接于连接套210时收容于收容凹槽229内，避免了第一锁紧件240和第二锁紧件250对穿刺于吨袋进行固定定位的过程中产生干涉，导致固定组件200穿刺于吨袋所受的阻力较大的问题。在本实施例中，尖刺端222的直径大于环绕部224的直径，使尖刺端222与环绕部224的连接处形成第一连接端面，第一连接孔225开设于第一连接端面。转动连接部226的直径等于环绕部224的直径，尖刺端222的直径等于连接套210的外径，连接套210套接于转动连接部226并与转动连接部226转动连接，由于尖刺端222的直径大于环绕部224的直径，使连接套210邻近尖刺端的一侧形成第二连接端面，第二连接孔215开设于第二连接端面，使尖刺端222与连接套210之间形成有收容凹槽229，进而使弹性件230、第一锁紧件240和第二锁紧件250均收容于收容凹槽229内，同时使弹性件230的第一端通过第一锁紧件240固定于第一连接端面，并使弹性件230的第二端通过第二锁紧件250固定于第二连接端面。
由于固定装置10用于对吨袋进行固定定位，使固定装置10的周围环境中存在较多的粉尘，由此不可避免地存在部分粉尘通过尖刺件220与连接套210的连接处进入，导致尖刺件220与连接套210的连接处存在磨损较严重的问题，为避免尖刺件220与连接套210的连接处存在磨损较严重的问题，如图15至图17所示，进一步地，连接套210邻近尖刺端222的端部形成有定位环槽216，定位环槽216环绕于尖刺端222设置。固定组件200还包括卡接密封环260，卡接密封环260活动套设于尖刺件220，且卡接密封环260设于定位环槽216内 并与连接套210弹性抵接，提高了尖刺件220与连接套210的连接处的密封性能，避免了尖刺件220与连接套210的连接处存在磨损较严重的问题，进而延长了固定组件200的使用寿命。
可以理解，由于尖刺件220与连接套210的连接处需要反复多次的相对运动，如尖刺件220与连接套210相对转动，随着使用时间或频率的增加，卡接密封环260存在磨损严重而无法起到较好的密封效果，如图15至图17所示，进一步地，卡接密封环260可拆卸连接于尖刺件220，以便对卡接密封环260进行定期更换，避免了卡接密封环260存在磨损严重而无法起到较好的密封效果的问题。更进一步地，卡接密封环260设有止档凸起261，定位环槽216内周壁上设有旋转限位挡块216a，旋转限位挡块216a与定位环槽216的底部之间存在卡入间隙，止档凸起用于在定位环槽216内旋转预定角度时旋入卡入间隙内，且止档凸起与旋转限位挡块216a抵接，使卡接密封环260卡接限位于定位环槽216内，同时使卡接密封环260可拆卸连接于尖刺件220。在本实施例中，卡接密封环260可以为硅胶环或橡胶环。为使卡接密封环260更紧密地弹性抵接于定位环槽216内，同时参见图18，进一步地，卡接密封环260的外周壁设有密封凸缘263，密封凸缘位于定位环槽216内并与连接套210弹性抵接，使卡接密封环260更紧密地弹性抵接于定位环槽216内。在本实施例中，密封凸缘的横截面呈三角形状或矩形状或梯形状，使密封凸缘位于定位环槽216内并与连接套210的内周壁紧密地连接，如此更好地避免了灰尘进入连接套与尖刺件的连接处的问题。
为使尖刺件220相对于连接套210转动的过程中更加平稳，如图1及图19所示，进一步地，固定装置10还包括支撑轴承300，支撑轴承300套设于尖刺件220，且支撑轴承300固定安装于周转箱100上，使尖刺件220凸出于周转箱100的外侧的端部相对于连接套210转动的过程中更加平稳，进而使尖刺件220相对于连接套210转动的过程中更加平稳。然而，由于固定装置10用于对吨袋进行固定定位，使固定装置10的周围环境中存在较多的粉尘，由此不可避免地存在部分粉尘进入支撑轴承300内导致支撑轴承300容易磨损的问题，如图20所示，进一步地，固定装置10还包括防尘罩400，防尘罩400包覆于支撑轴承300，且防尘罩400开设有第一避位孔402和第二避位孔404，尖刺件220分别穿设于第一避位孔402和第二避位孔404。在本实施例中，第一避位孔402的内周壁上凸设有第一密封环402a，第二避位孔404的内周壁上凸设有第二密封环404a，第一密封环402a和第二密封环404a均套设于尖刺件220上，使支撑轴承300密封设置于防尘罩400内，进而使固定装置10的周围环境中粉尘不易进入防尘罩400内，提高了支撑轴承300的使用寿命。更进一步地，防尘罩400的侧壁上开设有注油孔406，注油孔406与支撑轴承300的滚珠对应设置，以便使用者定期通过注油孔406对支撑轴承300进行保养维护，进一步地提高了支撑轴承300的使用寿命。
为提高吨袋的固定定位可靠性，如图1所示，在其中一个实施例中，固定组件200的数目为多个，多个固定组件200间隔分布，使吨袋通过多个固定组件200对吨袋进行固定定位，提高了吨袋的固定定位可靠性。在本实施例中，多个固定组件200间隔分布于周转箱100的 底部，使多个固定组件200均对吨袋的底部进行固定定位。
如图1所示，在其中一个实施例中，尖刺件220凸出于周转箱100的外侧的端部设有扳手配合部221，使用时，可通过扳手工具作用于扳手配合部221，以使尖刺件220相对于连接套210转动，提高了固定组件200的使用方便性。在本实施例中，扳手配合部221为方形截面的扳手固定卡扣。同时参见图2，进一步地，固定装置10还包括固定架600，固定架600固定并支撑于周转箱100，固定架600的侧壁上形成有镂空腔601，扳手配合部221位于镂空腔，采用扳手工具通过镂空腔作用于扳手配合部221。
可以理解，在其他实施例中，不仅限于通过设置扳手配合部221的方式来转动尖刺件220凸出于周转箱100的外侧的端部，使弹性件230产生弹性形变，以形成螺旋外凸弹性结构，使螺旋外凸弹性结构对吨袋的内壁进行弹压和固定作用。如图21和图22所示，在其中一个实施例中，固定装置10还包括固定架600和驱动机构700，固定架600固定并支撑于周转箱100，驱动机构700安装于固定架600上，且驱动机构700的动力输出端与尖刺件220凸出于周转箱100的外侧的端部连接，使驱动机构700驱动尖刺件220相对于连接套210转动，使弹性件230产生弹性形变，以形成螺旋外凸弹性结构，使螺旋外凸弹性结构对吨袋的内壁进行弹压和固定作用。在本实施例中，驱动机构700可以为电机驱动机构。
如图21和图22所示，在其中一个实施例中，固定组件200的数目为多个，多个固定组件200并排设置于周转箱100上。固定装置10还包括多个传动齿轮800，多个传动齿轮800一一对应套设于多个固定组件200的尖刺件220上，且多个传动齿轮800均位于周转箱100的外侧，多个传动齿轮800沿多个固定组件200的排列方向依次啮合传动，且其中一个固定组件200的尖刺件220与驱动机构700的动力输出端连接。当驱动机构700驱动其中一个固定组件200的尖刺件220相对于相应的连接套210转动时，该固定组件200对应的传动齿轮800将驱动机构700的动力传导至其他传动齿轮800，如此实现多个固定组件200的尖刺件220同时相对于相应的连接套210转动，进而实现多个固定组件200同时对周转箱100内的吨袋进行固定定位或解除固定定位，进一步地提高了固定装置10的使用方便性。在本实施例中，相邻两个固定组件200的弹性件230螺旋环绕抵接于相应的尖刺件220的外周壁的螺旋方向相反，如此，当驱动机构700驱动其中一个固定组件200的尖刺件220相对于相应的连接套210转动时，相邻的两个固定组件200的尖刺件220旋转的方向相反，使多个固定组件200的弹性件230均能够同时产生弹性形变或解除弹性形变，进而实现多个固定组件200同时对周转箱100内的吨袋进行固定定位或解除固定定位。
与现有技术相比，本发明至少具有以下优点：
1、本发明的固定组件200，连接套210可以固定安装于安装位置，如连接套210可以固定安装于周转箱100的放置槽的内壁，由于尖刺件220与连接套210转动连接，且弹性件230的一端连接于连接套210，弹性件230的另一端连接于尖刺件220，弹性件230至少螺旋环绕于尖刺件220的外周壁上，在吨袋放置于周转箱100内的放置槽内，并使尖刺件220刺穿并 插入吨袋的面层时，使尖刺件220沿与弹性件230的螺旋环绕方向相反的方向相对于所述连接套210转动，又由于弹性件230用于在尖刺件220沿与弹性件230的螺旋环绕方向相反的方向相对于连接套210转动时产生弹性形变，弹性形变的方向与尖刺件220的轴向延伸方向存在夹角，使弹性件230外弹并形成往尖刺件220的外周壁向外张开的螺旋外凸弹性结构，起到对吨袋的内壁进行弹压和固定作用，如此起到类似于“钉帽”的固定限位作用，如此实现对吨袋起到较好的固定作用，即使吨袋较好地固定定位于周转箱100内，以便对吨袋进一步地倒料操作，实现吨袋的固定定位的整个过程方便快捷，解决了吨袋定位难度较高的问题；
2、本发明的固定组件200，当不需要固定吨袋时，仅需使尖刺件220沿与弹性件230的螺旋环绕方向相同的方向相对于连接套210转动，即可使弹性件230自动复位并旋转收紧环绕于尖刺件220的外周壁上，即螺旋外凸弹性结构内缩并紧贴于尖刺件220的外周壁表面，亦即是弹性件230螺旋环绕抵接于所述尖刺件220的外周壁上，此时尖刺件220能够从吨袋的面层快速拔出，实现不用固定定位时可以马上解除固定的状态，同时避免了吨袋的结构因固定定位而遭受破坏的问题，实现吨袋循环使用；
3、本发明的固定组件200，在尖刺件220刺穿并插入吨袋的面层时，使尖刺件220相对于所述连接套210正、反方向转动，即可实现固定组件200对吨袋进行固定定位与解除固定定位的两种不同状态的快速切换，大大提高了固定组件200的使用方便性及定位效率。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
