Small road pavers design
Abstract: Currently, in municipal roads and highways construction, the main application is the large road pavers. However, for small-scale or small area on-site construction, large road pavers are not qualified. Therefore, the small road pavers are particularly important. China's current small-scale road pavers’ production volume and variety still small and the prices are relatively high. Therefore, this paper aims to study the small road pavers’ relevant parameters and structure to achieve the desired work requirements, reduce production costs. This article is completed by theoretical analysis and calculation of small road paver’s frame, deep tone means and work equipment - mixing rotor design. In the power plant, taking into account the requirements of the site can use the motor power limitations, so choose the engine as the driving force. Transmission mainly for the belt drive, the content includes choice of belt type and the pulley design. The design content of work device includes mixing shaft design, calculation and checking the shaft and the shaft parts fixation, etc. Deep tone means mainly through the rear support wheel angle adjustment to achieve the depth of the threaded rod control mixing.
Keywords: small road pavers design; mixing rotor; the device of depth adjust; the belt drive; Mixing Tools
