A roller scraping device, solves the problem of surface bonding sand cleaning roller, which comprises a supporting seat, shaft, connecting arm and the connecting arm of A B, the weight, the sand scraping plate; the supporting seat is fixed; shaft mounted on the supporting seat, in parallel with the roller shaft connecting arm and the connecting arm; A B each other in a certain angle setting can rotate around the axis to axis and in the week, weights and scraping plates are respectively fixed at the end part of the connecting arm and the connecting arm of A B; the axis of the torque is greater than the weight to the sand scraping plate to the axis of the torque; the circumference of the cylinder surface in the rotating track sand scraping plate in circumferential contact; is the sand scraping plate and the end of the drum, there is in contact with the angle between the sand scraping plate at the section of the drum and the sand scraping plate; the utility model has the advantages of simple structure, convenient and efficient, and can work in drum cleaning up sediment, reducing the generation of wear and belt deviation at The utility model can adjust the clearance between the scraping plate and the roller to the maximum extent by the lever principle, and plays the role of protecting the belt and the equipment.
【技术实现步骤摘要】
滚筒刮砂装置
本专利技术涉及混凝土搅拌站的斜皮带机,具体涉及斜皮带改向滚筒刮砂装置。
技术介绍
混凝土搅拌站的斜皮带机在皮带运行一段时间以后,改向滚筒上会粘上许多皮带带来的泥沙混合物,形成一定高度的凸起,从而对皮带产生磨损,并引起皮带跑偏,因此需要对改向滚筒进行清理。因此,往往导致浪费时间,耗费人力。
技术实现思路
为了解决以上问题,本专利技术提供一种结构简单、可在工作的同时进行对滚筒表面进行清理的刮砂装置。本专利技术所述滚筒刮砂装置,包括支撑座、轴、连接臂A和连接臂B、配重、刮砂板;支撑座被固定不动;轴安装在支撑座上,与滚筒轴平行;连接臂A和连接臂B彼此成一定夹角设置在轴的周向且可绕轴心转动,配重和刮砂板分别固定在连接臂A和连接臂B的端部;配重到轴心的力矩大于刮砂板到轴心的力矩;滚筒的圆周面在刮砂板的旋转轨迹内;刮砂板端部与滚筒的圆周面相触,滚筒在与刮砂板相触处的切面与刮砂板之间有夹角。本专利技术所述改向滚筒刮砂装置,通过杠杆原理,在配重的作用下,自动调节刮砂板与滚筒之间的缝隙,从而达到清理滚筒表面粘结泥沙的目的。当泥沙粘结力较小时,刮砂板可将泥沙清理干净;若遇到粘 ...
