Cement trowelling device for road construction
The invention discloses a cement trowelling device for road construction. The cement trowelling device for road construction comprises a trowelling machine body, the trowelling machine body comprises a supporting frame, one end of the supporting frame is fixedly connected with a fixing frame, a telescopic rod is rotationally arranged on the fixing frame, the two sides of one end of the telescopic rod are fixedly connected with a pair of fixing rods, the fixing rods are fixedly connected with handles, and the handles are sleeved with rubber sleeves; a driving motor is fixedly connected to the supporting frame, a rotating shaft is fixedly installed at the output end of the driving motor, a trowelling mechanism is fixedly connected to the bottom of the rotating shaft and comprises a rotating disc, the rotating disc is fixedly arranged at the bottom of the rotating shaft, and a plurality of trowelling frames are arranged on the rotating disc; compared with the prior art, the ejector rod is ejected outwards under the action of air pressure in the air pressure cavity, aggregate gravel and the like on the surface of cement are jacked into the cement, the trouble of replacing a troweling plate and a spatula is avoided, meanwhile, interaction force is generated after the ejector block collides with the aggregate, an elastic plate and a first spring can be driven to shake, and the cement at the bottom of the ejector rod is shaken off; and cement is prevented from remaining at the bottom of the ejector rod.
本发明公开了一种道路施工用水泥抹平装置，包括抹平机本体，抹平机本体包括支撑架，支撑架一端固连接固定架，且固定架上转动设有伸缩杆，伸缩杆一端两侧固定连接有一对固定杆，固定杆上固定连接有把手，且把手上套设有橡胶套，支撑架上固定连接有驱动电机，驱动电机输出端上固定安装有转轴，转轴底部固定连接有抹平机构，抹平机构包括转盘，转盘固定设置在转轴底部，转盘上开设有多个抹刀架；与现有技术相比，使顶杆在气压腔内气压作用下向外顶出，将水泥表面的骨料碎石等顶进水泥内，避免了更换抹平板和抹刀的麻烦，同时顶块在与骨料撞击后产生相互作用力，能够带动弹性板和第一弹簧抖动，使顶杆底部水泥抖落，避免水泥残留在顶杆底部。
