Description
技术领域
本实用新型涉及周护板技术领域，更具体的是涉及一种用于制砂机的高效撞击机构。
背景技术
制砂机是筑、矿山、冶金行业以及高速公路、铁路、桥梁、水电、矿物粉磨领域及机制砂行业的核心设备。制砂机(离心冲击破碎机)广泛应用于各种金属和非金属矿、水泥、耐火材料、磨料、玻璃原料、建筑骨料，机制砂、冶金等行业。适用中细碎不同硬度的各种矿石和岩石，如铁矿石、有色金属矿石、金刚砂、铝矾土、石英砂、棕刚玉、珍珠岩、玄武岩等高硬度物料的中细碎作业。
制砂机工作原理：物料由进料斗进入破碎机，经分料器将物料分成两部分，一部分由分料器中间进入高速旋转的叶轮中，在叶轮内被迅速加速，其加速度可达数百倍重力加速度，然后以60-70米/秒的速度从叶轮三个均布的流道内抛射出去，首先同由分料器四周自收落下的一部分物料冲击破碎，然后一起冲击到涡支腔内物料衬层或周护板上，物料发生反弹，斜向上冲击到涡动腔的顶部，又改变其运动方向，偏转向下运动，从叶轮流道发射出来的物料形成连续的物料幕，一块物料在涡动破碎腔内受到两次以至多次机率撞击、磨擦和研磨破碎作用，被破碎的物料由下部排料口排出，排料口和循环筛分系统形成闭路，一般循环三次即可将物料破碎成20目以下。
专利号为201410408890.X提供一种制砂机通孔式周护板，直棱柱形的周护板可根据磨损面的磨损严重程度，调换撞击面或更换冲击块，从而使得周护板的使用时间长，降低成本，也在一定程度上解决了圆柱形周护板的磨损程度不均匀的问题，从而节约了人力成本和材料成本。但是通过视窗观察周护板磨损面的磨损程度不太方便，因为磨损面使面对物料而背对视窗，观察时需要旋转周护板，而且菱形周护板并不能完全解决周护板磨损程度不均匀的问题。
实用新型内容
本实用新型的目的在于：为了解决圆柱形周护板侧面磨损程度不均匀的问题，本实用新型提供一种用于制砂机的高效撞击机构。
本实用新型为了实现上述目的具体采用以下技术方案：
一种用于制砂机的高效撞击机构，包括上固定环、下固定环和多组冲击块，所述多组冲击块按圆周均布在上固定环和下固定环之间，每组冲击块包括冲击块主体和设置在冲击块主体主体上下两端的且同轴线上转轴和下转轴，上转轴和下转轴分别通过轴承连接有上固定环和下固定环，所述下固定环底端连接有驱动多组冲击块旋转的驱动机构。多组冲击块按圆周均布在上固定环和下固定环之间形成周护板，驱动机构能让冲击块快速旋转，使冲击块侧面磨损程度均匀，减小了周护板的更换频率，从而延长周护板的使用寿命。
进一步地，所述下转轴下端均贯穿下固定环并设有齿轮，所述齿轮均位于同一水平面，所述驱动机构包括与所有齿轮啮合的齿圈，其中一个下转轴的齿轮的转轴与电机的输出轴连接，所述电机下端设有环形支撑板。齿圈可以仅使用一个电机驱动所有冲击块旋转，节省了制砂机运行成本同时节约能源。
进一步地，所述冲击块主体为圆柱体，所述圆柱体外侧均设有齿，相邻两个冲击块主体之间啮接，所述驱动机构为电机，其中一个下转轴连接有电机的输出轴，所述电机下端设有环形支撑板。冲击块主体之间啮接，可以仅使用一个电机驱动所有冲击块旋转，节省了制砂机运行成本同时节约能源。
进一步地，所述冲击块侧面竖直方向等间距设有多组螺纹孔，所述冲击块侧面设有多个粉碎机构，所述粉碎机构包括与所述螺纹孔对应的带孔固定环，所述带孔固定环上设有多个撞击块，所述撞击块向下倾斜。在制砂机运作过程中，冲击块两端磨损程度远远低于中间段的磨损程度，冲击块的不同水平面设置粉碎机构，可以在两端磨损程度不严重的情况下，仅更换中间段磨损严重的粉碎机构。当物料水平或斜向下撞向冲击块时，向下倾斜的撞击块可以使物料在上下两层撞击块中来回撞击；当物料刚好落在同一破碎机构的两个撞击块之间时，伴随冲击块旋转的撞击块让物料受到撞击块更大的作用力。因此，向下倾斜的撞击块以及旋转的冲击块，大大增加了制砂机的破碎效率，同时节约了制砂机的运行成本。
进一步地，所述环形支撑板与下固定环之间竖直设有圆弧形挡板，圆弧形挡板位于齿圈内部。圆弧形挡板可以保护驱动机构不被物料砸中而损坏。
进一步地，所述电机外设有保护箱。保护箱可以保护电机不被物料砸中而损坏。
进一步地，所述冲击块为圆柱体或长方体。
本实用新型的有益效果如下：
1、本实用新型所述多组冲击块按圆周均布在上固定环和下固定环之间，每组冲击块包括冲击块主体和设置在冲击块主体主体上下两端的且同轴线上转轴和下转轴，上转轴和下转轴分别通过轴承连接有上固定环和下固定环，所述下固定环底端连接有驱动多组冲击块旋转的驱动机构。多组冲击块按圆周均布在上固定环和下固定环之间形成周护板，驱动机构能让冲击块快速旋转，使冲击块侧面磨损程度均匀，减小了周护板的更换频率，从而延长周护板的使用寿命。
2、本实用新型下转轴下端均贯穿下固定环并设有齿轮，所述齿轮均位于同一水平面，所述驱动机构包括与所有齿轮啮合的齿圈，其中一个下转轴的齿轮的转轴与电机的输出轴连接，所述电机下端设有环形支撑板。齿圈可以仅使用一个电机驱动所有冲击块旋转，节省了制砂机运行成本同时节约能源。
3、本实用新型冲击块主体为圆柱体，所述圆柱体外侧均设有齿，相邻两个冲击块主体之间啮接，所述驱动机构为电机，其中一个下转轴连接有电机的输出轴，所述电机下端设有环形支撑板。冲击块主体之间啮接，可以仅使用一个电机驱动所有冲击块旋转，节省了制砂机运行成本同时节约能源。
4、本实用新型冲击块侧面竖直方向等间距设有多组螺纹孔，所述冲击块侧面设有多个粉碎机构，所述粉碎机构包括与所述螺纹孔对应的带孔固定环，所述带孔固定环上设有多个撞击块(3-22)，所述撞击块向下倾斜。在制砂机运作过程中，冲击块两端磨损程度远远低于中间段的磨损程度，冲击块的不同水平面设置粉碎机构，可以在两端磨损程度不严重的情况下，仅更换中间段磨损严重的粉碎机构。当物料水平或斜向下撞向冲击块时，向下倾斜的撞击块可以使物料在上下两层撞击块中来回撞击；当物料刚好落在同一破碎机构的两个撞击块之间时，伴随冲击块旋转的撞击块让物料受到撞击块更大的作用力。因此，向下倾斜的撞击块以及旋转的冲击块，大大增加了制砂机的破碎效率，同时节约了制砂机的运行成本。
5、本实用新型环形支撑板与下固定环之间竖直设有圆弧形挡板，圆弧形挡板位于齿圈内部。圆弧形挡板可以保护驱动机构不被物料砸中而损坏。
6、本实用新型电机外设有保护箱。保护箱可以保护电机不被物料砸中而损坏。

多组冲击块3按圆周均布在上固定环1和下固定环2之间，形成周护板，上转轴3-11和下转轴3-12分别与上固定环1和下固定环2轴承连接，驱动机构4能让冲击块3快速旋转，使冲击块3侧面磨损程度均匀，减小了周护板的更换频率，从而延长周护板的使用寿命。
实施例2
如图1到3所示，本实施例在实施例1的基础上做了进一步改进，具体是所述下转轴3-12下端均贯穿下固定环2并设有齿轮，所述齿轮均位于同一水平面，所述驱动机构4包括与所有齿轮啮合的齿圈4-1，其中一个下转轴3-12的齿轮的转轴与电机4-2的输出轴连接，所述电机4-2下端设有环形支撑板5，所述环形支撑板5与下固定环2之间竖直设有圆弧形挡板6，圆弧形挡板6位于齿圈4-1内部。
齿圈4-1可以实现用一个电机4-2驱动所有冲击块3旋转，节省了制砂机运行成本，同时节约能源。圆弧形挡板6可以保护驱动机构4。
实施例3
如图1到图2所示，本实施例在实施例1的基础上做了进一步改进，具体是所述冲击块主体3-1为圆柱体，所述圆柱体外侧均设有齿，相邻两个冲击块主体3-1之间啮接，所述驱动机构4为电机4-2，其中一个下转轴3-12连接有电机4-2的输出轴，所述电机4-2下端设有环形支撑板5，所述电机4-2外设有保护箱。冲击块主体3-1之间啮接，可以仅用一个电机4-2驱动所有冲击块3旋转，节省了制砂机运行成本同时节约能源。
实施例4
如图1到3所示，本实施例在实施例2的基础上做了进一步改进，具体是所述冲击块3侧面竖直方向等间距设有多组螺纹孔，所述冲击块3侧面设有多个粉碎机构3-2，所述粉碎机构3-2包括与所述螺纹孔对应的带孔固定环3-21，所述带孔固定环3-21上设有多个撞击块3-22，所述撞击块3-22向下倾斜。
在制砂机运作过程中，冲击块3两端磨损程度远远低于中间段的磨损程度，冲击块3的不同水平面设置粉碎机构3-2，粉碎机构3-2与冲击块3可拆卸连接，可以在两端磨损程度不严重的情况下，仅更换中间段磨损严重的粉碎机构3-2。当物料水平或斜向下撞向冲击块3时，向下倾斜的撞击块3-22可以使物料在上下两层撞击块3-22中来回撞击；当物料刚好落在同一破碎机构3-2的两个撞击块3-22之间时，伴随冲击块3旋转的撞击块3-22让物料受到撞击块3-22更大的作用力。因此，向下倾斜的撞击块3-22以及旋转的冲击块3，大大增加了制砂机的破碎效率，同时节约了制砂机的运行成本。
实施例5
如图1所示，本实施例在实施例1的基础上做了进一步改进，具体是所述冲击块3为圆柱体或长方体。
