The utility model discloses a self-cleaning device for roller sieve, which comprises a roller sieve housing, a horizontal roller inside the roller sieve housing, a roller sieve on the roller shaft, a roller sieve tooth on the roller sieve, a sweeping plate at the lower end of the roller, a slide rail connected by a pulley at both ends of the sweeping plate, a driving cylinder connected at the lower end of the sweeping plate, and a driving cylinder arranged on the inner wall of the roller sieve housing. There are several limit protrusions. The inside of the limit protrusion is provided with magnetic switches, which are attached to the driving cylinder, and the cleaning board is provided with several cleaning mechanisms. The utility model can adjust the position of the cleaning mechanism by setting a lifting cleaning board inside the roller screen, so that the cleaning mechanism can be inserted into different depths to clean the teeth of the roller screen. There are inclined scrapers and brushes inside the cleaning mechanism, which can effectively remove and remove the internal residual dirt, and improve the cleaning ability of the cleaning mechanism, which is worth promoting.

一种滚轴筛自清扫装置
本技术涉及滚轴筛
,具体为一种滚轴筛自清扫装置。
技术介绍
滚轴筛的筛面由很多根平行排列的、其上交错地装有筛盘的滚轴组成,滚轴通过链轮或齿轮传动而旋转,其转动方向与物料流动方向相同。滚轴筛全部为座式,有左传动和右传动之分,又分带走轮和不带走轮的,带走轮的可在钢轨上移动。由于筛轴是按不同的工作角度布置的,所以当物料在工作角度较高的位置运行时速度较快;当物料在工作角度较低的位置运行时速度较平缓。两种不同速度运行下的物料,在筛面某一位置相汇时开始做轴向运动,这样就使物料均匀地分布在筛面上,达到了提高筛分效率的目的。申请号为CN201420396111.4,名称为一种滚轴筛自清扫装置总成的技术专利,包括滚轴筛,滚轴筛设置有滚轴筛齿,所述滚轴筛外侧滚轴筛护罩上设置有支撑梁,所述支撑梁轴线与滚轴筛的轴线相互平行,支撑梁上设置有与支撑梁轴线相垂直的三角状梳齿;所述设置有三角状梳齿的支撑梁表面设置有向实体内侧凹陷的圆弧形凹槽,该技术滚轴筛自清扫装置总成,给筛板上加上梳齿进行筛板间的清扫,保证筛板之间的粘煤不会堵住,利用滚轴本身的转动将筛板间的粘煤刮下来 ...
