Description

一种新型振动筛阻尼支撑装置
技术领域
本发明涉及振动筛领域，特别是一种新型振动筛阻尼支撑装置。
背景技术
振动筛分机械通常由激振器、工作机体和阻尼支撑部件三部分组成。阻尼支撑部件用作支撑和减少传给基础或结构架的动载荷，常用的阻尼元件有金属螺旋柱弹簧、金属螺旋锥弹簧、橡胶弹簧、金属螺旋柱外裹胶复合弹簧、橡胶空气弹簧等。其中橡胶弹簧是一种应用广泛的阻尼元件，但这种阻尼元件布置方式单一，振动筛对底部基础的冲击较大，也增加了生产现场的噪音。
发明内容
针对现有技术缺乏存在的不足，本发明提供一种新型振动筛阻尼支撑装置。
为实现上述目的，本发明提供一种新型振动筛阻尼支撑装置，其特征在于，包括活塞杆2、活塞3和橡胶弹簧4；活塞杆2安装在上支撑座1；活塞3安装在活塞杆2底部；橡胶弹簧4安装在下支撑座5；
所述橡胶弹簧4中心有阶梯孔，阶梯孔有一段锥面，阶梯孔的轴心线与活塞杆2、活塞3的轴心线重合，阶梯孔的最小直径大于活塞3的直径。
与现有技术相比，本发明的有益效果在于：
1)活塞在阶梯孔内运动会受到压强的作用，提供一个阻尼，与橡胶弹簧形成双阻尼，提高减振减冲击的效果；
2) 活塞提供的阻尼先于上支撑座接触橡胶弹簧，可抵消一部分冲击，延长橡胶弹簧的寿命；
3) 该结构简单紧凑，装置容易实现，容易制造，实现成本较低。
附图说明
为了更清楚的说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单的介绍。
图1为本发明的整体结构示意图；
图2为本发明中各部分尺寸示意图；
图中：1上支撑座，2活塞杆，3活塞，4橡胶弹簧，5下支撑座。
具体实施方式
下面结合附图和实施例对本发明作进一步的详细说明，显然，这里所描述的仅仅是本发明的一部分实例，并不是全部实例，对本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
如图1和图2所示，一种新型振动筛阻尼支撑装置，包括活塞杆2、活塞3和橡胶弹簧4；活塞杆2安装在上支撑座1；活塞3安装在活塞杆1底部；橡胶弹簧4安装在下支撑座5；橡胶弹簧4中心有阶梯孔，阶梯孔有一段锥面，锥面的角度为θ，阶梯孔的轴心线与活塞杆2、活塞3的轴心线重合，锥面的最小直径为d1，d1应大于活塞3的直径；锥面的最大径为d2，尺寸取值范围如下：d1+0.1mm < d2< d1+10mm， 10°<θ<180°， d1视橡胶弹簧4的尺寸规格而定。
当振动筛受到向下的激振力时，与重力会叠加一个较大的激振力，橡胶弹簧4与活塞3会产生两个阻尼，而活塞3和阶梯孔内部的气压会首先抵消振动筛的冲击，能减少振动筛对橡胶弹簧4的直接冲击，由于锥面的存在，活塞3向下运动时，气压会不断增加，阻尼也不断增加，活塞3提供的阻尼先于上支撑座1接触橡胶弹簧4，可抵消一部分冲击，延长橡胶弹簧4的寿命。同时，此装置结构简单紧凑，装置容易实现，容易制造，实现成本较低。
