Description

最小安装斗距的斗式提升机用畚斗 技术领域
本发明属于斗式提升机领域，斗式提升机是用于垂直提升散状物料的设备，具体是安装在斗式提升机上的畚斗，用于装载被提升物料。
背景技术
斗式提升机是通过安装在传动带或传动链上的多个畚斗将提升机底部的物料垂直提升到顶部，畚斗沿顶部驱动轮旋转运动产生离心力或重力，从而将物料抛出或倾倒出卸料，达到提升物料的目的。
斗式提升机的主要技术参数是提升量，提升量决于单位时间内提升至顶部的物料多少，在传动带或传动链线速度相同的前提下，取决于传动带或传动链的单位长度的所载物料容积，而单位长度所载物料容积又取决于单位长度内畚斗的安装数和畚斗容积。由此可见，提高斗式提升机传动带或或传动链单位长度内的畚斗安装密度可提高斗式提升机的提升量。
为了提高畚斗的安装密度，PCT专利申请号为PCT/US2015/016795、公开号为WO 2015/127188 A1的文献中公布了一种用于斗式提升机的畚斗，该畚斗的一对侧板的上边缘设计成波形或者曲线形，安装时，将上一个畚斗的底面嵌套于下一个畚斗的上部开口上方，以此减少上下畚斗之间的安装斗距，并且将一对侧板的前上端部设计成突出的斗耳形状，以此增加畚斗的容积。但这种畚斗存在的问题是：由于一对侧板是垂直板，上下畚斗安装时，仅仅是通过下方畚斗侧板上边缘和上方畚斗侧板底面外形轮廓相似嵌套，并不是完全接触式或者重叠式嵌套，上下畚斗之间仍然留有大约0.25英寸的距离，对畚斗安装斗距有一定的限制作用，并不能更大可能地缩小斗距和进一步提升斗式提升机的提升量。
发明内容
本发明的目的是为了解决上述现有斗式提升机用畚斗存在的问题，提出一种具有最小安装斗距的斗式提升机用畚斗的结构，在畚斗容积不减小的前提下，将上下两个畚斗重叠式嵌套，以提高畚斗的安装密度，从而提高斗式提升机的提升量。
为实现上述目的，本发明采用如下技术方案：本发明由左右两侧板、后背板和前底板围成，其特征是：其下半部分是一个内腔容积向下逐渐缩小的锥体，斗式提升机上的上方畚斗的锥体底部向下伸在下方畚斗后背板的前方。
进一步地，上下两个畚斗之间最小空间距离等于或大于5mm。
进一步地，所述的左右两侧板左右对称，左侧板由上方的左直立板和下方的左过渡斜板组成，左过渡斜板是在左直立板的底部处折弯并向右下方逐渐延伸的一块上大下小的梯形斜板；所述的右侧板由上方的右直立板和下方的右过渡斜板组成，右过渡斜板是在右直立板的底部处折弯并向左下方逐渐 延伸的一块上大下小的梯形斜板；所述的后背板由后板和后过渡斜板组成，后板是一块上下垂直的上大下小的梯形斜板，后过渡斜板是在后板的底部处折弯并向前下方延伸形成的一块斜板；所述的前底板是从后过渡斜板的底部处折弯并向前上方逐渐延伸形成的一块带多个折弯的弧形板；所述的锥体是由左过渡斜板、右过渡斜板、后过渡斜板和前底板围成的锥体。
本发明采用上述技术方案后具有的技术效果是：
1、本发明通过对畚斗结构的优化设计，在不影响畚斗容积的前提下，使畚斗的侧面、后背以及前底面形成一个向下缩小的锥体，使上一个畚斗底部沉入在下一个畚斗的后背前端，最大可能地降低畚斗安装斗距，加大畚斗安装密度，以提高斗式提升机的提升量，可使畚斗安装密度及提升量都提高25～35％。
2、本发明可以根据斗式提升机不同的使用设计要求调节畚斗的安装斗距，直至在最小安装斗距的范围内调节安装。
3、本发明能减小畚斗的包装体积，畚斗包装体积缩小30～40％，节省了仓储和物流成本。

具体实施方式
参见图1所示的斗式提升机，其底部是进料口11，进料口11的上方是提升带12，提升带12由动力装置带动上升，在提升带12上安装多个相同的畚斗13。散状物料先通过进料口11进入到畚斗13中，然后通过动力装置垂直提升到斗式提升机顶部14，最后畚斗13沿安装在提升机顶部14的驱动轮作旋转运动，产生离心力或重力，将物料抛出或倾倒至出料口15卸料。
参见图2-8所示，每个畚斗13都是由左右两侧板、后背板和前底板围成，围成一个用于盛放散状物料的内腔，畚斗13的上口敞开便于装料与卸料。其中，左右两侧板结构相同，相对于畚斗13的中心左右对称，各由上方的直立板和下方的过渡斜板组成。左侧板由上方的左直立板2和下方的左过渡斜板4组成，右侧板由上方的右直立板1和下方的右过渡斜板3组成，后背板由后背部的后板5和后过渡斜板6组成。后板5上开有多个安装孔8，通过安装孔8和螺栓将畚斗固定在提升带12上。
左过渡斜板4是在左直立板2的底部处折弯并向右下方逐渐延伸的一块上大下小的梯形斜板，右过渡斜板3是在右直立板1的底部处折弯并向左下方逐渐延伸的一块上大下小的梯形斜板，后板5是一块上下垂直的上大下小的梯形斜板，后过渡斜板6是在后板5的底部处折弯并向前下方延伸形成的一块斜板，前底板7是从后过渡斜板6的底部处折弯并向前上方逐渐延伸形成的一块带多个折弯的弧形板。由此，整个畚斗13的下半部分是由左过渡斜板4、右过渡斜板3、后过渡斜板6和前底板7围成的一个内腔容积向下逐渐缩小的锥体，该锥体是一个侧面是四个面的四面锥体。
左直立板2与右直立板1的上端近前口处呈向上突出的圆弧形状，该结构可使畚斗左右两侧板近前口处的装料高于畚斗前口，提高了畚斗的装满系数，尤其在安装斗距偏小时，畚斗装料较为集中在畚斗前部时效果更优。突出的圆弧形状的后端面通过向后下方倾斜的直面连接于后板5的顶面，在不影响实际装满系数的前提下，降低后背板的高度，进一步增大了畚斗安装密度。
左过渡斜板4与左直立板2的折弯角度β＝8～12°，右过渡斜板3与右直立板1之间的折弯角度β＝8～12°，即左过渡斜板4与左直立板2的外侧表面之间的锐角夹角β＝8～12°，右过渡斜板3与右直立板1的外侧表面之间的锐角夹角β＝8～12°。这样，左右两侧板在呈β角度的折弯处形成一个加强结构，增加了左右两侧板上端近前口处呈向上突出的圆弧形状在装料时的抗变形能力。
后板5与后过渡斜板6的折弯角度α＝35～55°，在安装时，可以避免上下两个畚斗的后背板之间的重叠和干涉现象。
畚斗的左右总长度是A，总长度A是左直立板2和右直立板1的两外侧面之间的左右最大长度。畚斗的前后总凸度是B，总凸度B是后背板的后侧面与前底板7的最前端前侧面间的前后最大宽度。总长度A和总凸度B要保证畚斗与提升机两侧机壳的安全运行间距。畚斗的上下总高度C1＝(0.89～1)*B，总高度C1是前底板7底面与左直立板2、右直立板1上端面间的最大高度。左右两侧板、后背板和前底板的板厚均是t＝5～15mm。总长度A和总凸度B都可以以20～25mm为间隔增加，相互配对形成畚斗的规格系列，且总长度A尺寸不小于70mm，总凸度B尺寸不小于50mm，在相互配对形成规格系列时，总长度 A尺寸应至少大于相配对的总凸度B尺寸20mm。
以前底板7的最底部为高度基准，后板5的上端面距离前底板7最底部的高度C2＝(0.78～0.87)*B。后过渡斜板6的上端面距离前底板7最底部的高度C3＝(3～4)*t。前底板7的总高C4＝(0.52～0.62)*B。后板5的上端面距离安装孔8中心的高度D＝C2-C4。
左过渡斜板4和右过渡斜板3的上端面与后板5相交于安装孔8中心位置，也就是左过渡斜板4在安装孔8中心位置处开始折弯，左过渡斜板4和右过渡斜板3的上端面与后板5相交处距离前底板7最底部的高度C5＝C2-D，即安装孔8的中心距离前底板7最底部的高度C5＝C2-D。左过渡斜板4和右过渡斜板3的上端面与前底板7的相交处距离前底板7最底部的高度C6＝(0.9～0.8)*C4。
左直立板2与右直立板1的上端近前口处呈向上突出的圆弧形状的圆弧中心与前底板7最前端的前后宽度B1＝(0.4～0.6)*B，圆弧半径R＝(0.4～0.6)*B。
参见图9和图10所示，本发明在使用时，上下两个畚斗13互相重叠嵌套，固定在提升带12上，上方畚斗13的下半部分锥体底部向下伸在下方畚斗13后背板的后板5前方。最小安装斗距S是在提升带12长度方向上相邻两个畚斗13的间隔距离，最小安装斗距S＝B-(2*t)-(25～35)。当上下两个畚斗13在最小安装斗距嵌套时，仍可保证上下两个畚斗13之间最小空间距离H等于或大于5mm，以保证在运行时不发生干涉或碰撞。
