Abstract

本实用新型公开了一种回转振动分级筛的尾部支撑板,该回转振动分级筛的尾部支撑板为两端宽中间细的弹性板,弹性板的两腰呈向内凹陷的弧形形状。本实用新型的回转振动分级筛的尾部支撑板,将常用的支撑板的形状改变为中间采用弧形过渡段,利用弧形来传递应力,从而改善尾部支撑板根部的受力状况,能够有效的延长支撑板使用寿命。同时,该回转振动分级筛的尾部支撑板还具有设计巧妙、节省材料、容易制作等优点。

Description

一种回转振动分级筛的尾部支撑板
技术领域
本实用新型涉及一种饲料行业中使用的回转振动分级筛,具体涉及一种回转振动分级筛的尾部支撑板。
背景技术
回转振动分级筛是一种常见的用于筛分的设备,在饲料行业中,常用于颗粒饲料的分级,其结构主要包括:筛船、支座和尾部支撑等。尾部支撑板作为尾部支撑的主要部件,一般是由尼龙板或电木等弹性材料制成,利用支撑板的弹性来支撑筛船的往复运动。回转振动分级筛工作时,频繁的往复折弯变形,容易在支撑板的根部造成应力集中,经常使支撑板发生断裂和损坏,从而影响支撑板的使用寿命。
发明内容
发明目的:针对现有技术中存在的不足,本实用新型的目的是提供一种回转振动分级筛的尾部支撑板,在保证支撑筛船往复运动的同时,减小支撑板根部应力集中,延长支撑板的使用寿命。
技术方案:为了实现上述发明目的,本实用新型采用的技术方案为:一种回转振动分级筛的尾部支撑板,所述尾部支撑板的为两端宽中间细的弹性板。
在回转振动分级筛上安装尾部支撑板时,可以采用两块尾部支撑板并列叠放安装,在尾部支撑板两端的安装段均使用第一垫板、第二垫板和第三垫板将两块尾部支撑板隔开。
有益效果:本实用新型的回转振动分级筛的尾部支撑板,将常用的支撑板的形状改变为中间采用弧形过渡段,利用弧形来传递应力,从而改善尾部支撑板根部的受力状况,能够有效的延长支撑板使用寿命。同时,该回转振动分级筛的尾部支撑板还具有设计巧妙、节省材料、容易制作等优点。
附图说明
图1是回转振动分级筛的结构示意图;
图2是尾部支撑板1的结构示意图;
图3是尾部支撑板1的安装结构示意图。
具体实施方式
下面结合附图对本实用新型做进一步的说明。
如图1所示,该回转振动分级筛的主要结构包括尾部支撑板1、筛船2和支座3,回转振动分级筛在工作时,尾部支撑板1随筛船2做前后往复高速运动。
如图2所示,尾部支撑板1由两端的安装段和中间的过渡段组成的弹性板,两端宽中间细即为安装段的宽度大于过渡段的宽度,弹性板的两腰呈向内凹陷的弧形或其他渐变曲线形状。典型的弹性板形状还包括呈哑铃形状。
如图3所示,在回转振动分级筛上安装尾部支撑板1时,采用两块尾部支撑板并列叠放安装,在尾部支撑板两端的安装端均使用第一垫板4、第二垫板5和第三垫板6将两块尾部支撑板隔开。
回转振动分级筛在工作时,尾部支撑板1随筛船2做前后往复高速运动,集中于尾部支撑根部的应力会沿着尾部支撑板1的弧形部分向中间扩散,从而改善尾部支撑板根部的受力状况,达到延长其使用寿命的目的。

Claims (3)
