室内墙壁用差动抹灰机研究

Research on Differential Plastering Machine for Indoor Wall

设计了一种旨在能够成功代替手工抹灰的墙壁抹灰机,分析了该机器的结构特点与工作原理,抹灰机由灰浆输送机构、差动抹灰机构、摆动导轨机构、灰厚控制装置、万向支撑小车和高度调整机构组成,其中差动抹灰机构以经过变异的差动轮系为基础,将甩灰叶轮、摊灰辊和抹灰板分别固接在小中心轮、系杆轮和大中心轮上,灰浆输送机构的螺旋滚筒通接差动抹灰机构小中心轮的空腔,甩灰叶轮将来自螺旋滚筒并经过小中心轮的灰浆甩于附近墙面,由摊灰辊摊平,由抹灰板压实抹平,较好地模拟了人工抹灰的动作,摆动导轨机构是为了使机器适应地面对墙壁的垂直度误差,灰厚控制装置用以调节墙壁抹灰厚度,万向支撑小车的锁定与解锁可以使抹灰机移动操作更为灵活和可靠。

A kind of wall plastering machine replacing manual work is designed. Its structural characteristics and working principle is analyzed. This machine is made up of a mortar transport mechanism, differential plastering mechanism, swing guide rail mechanism, a mortar thickness controlling device, a universal support pushcart and adjusting height mechanism. The differential plastering mechanism is based on changed differential gear train, then flick mortar impeller, spread mortar roller and rendering trowel is fixed on the small centre gear, tie rod wheel and big centre gear respectively. The spiral cylinder of the mortar transport mechanism is installed in cavity of the small centre gear of the differential plastering mechanism. The mortar came from the spiral cylinder and pass the cavity of the small centre gear, then the mortar is flick to nearby wall by the flick mortar impeller, spread out by the spread mortar roller, compacting and floating by the rendering trowel. Manual plastering action is simulated bitterly. The swing guide rail mechanism is used to adjust to error of perpendicular degree of ground surface to wall. The mortar thickness controlling device is used to regulate the mortar thickness. Moving operation of plastering machine is more agile and reliable by means of lock and unlock of the universal support pushcart.
