Device for uniformly spreading stone chips after municipal road construction

ZHANG LIPEI

The invention discloses a device for uniformly spreading stone chips after municipal road construction. The device comprises a base, wherein the upper end of the base is fixedly connected with a material guiding box, the upper end of the material guiding box is communicated with a feeding frame, two sliding grooves are formed in the opposite inner walls of the feeding frame, baffles are rotatablyconnected to the inner walls of the two sliding grooves, and adjusting mechanisms for adjusting the rotating angles of the baffles are installed in the two sliding grooves. According to the invention,a lead screw rotates, a lead screw nut drives the baffles to rotate through a connecting rod, the distance between the two baffles is adjusted, and the spilling amount of the stone chips in unit timecan be conveniently adjusted, thereby avoiding the situation that much stone chips exist in a certain area, time need to be spent in paving the stone chips, and the paving efficiency of the road stone chips is reduced. Through rotation of the reciprocating lead screw, a sliding block drives a transverse plate and scraping teeth to slide back and forth through a telescopic mechanism, the stone chips on a road are scraped, and uniform extrusion and horizontal paving of the stone chips by a subsequent extrusion roller are facilitated.

本发明公开了一种市政道路施工后的石屑均匀洒布装置，包括底座，所述底座上端固定连接有导料箱，所述导料箱上端连通有进料框，所述进料框相对内壁开设有两个滑槽，两个所述滑槽内壁转动连接有挡板，两个所述滑槽内安装有对挡板的转动角度进行调节的调节机构。本发明通过丝杠转动使得丝杠螺母通过连接杆带动挡板转动，对两个挡板之间的距离进行调节，进而便于对在单位时间内石屑的洒出量进行调节，避免某个区域内石屑较多，需要花费时间对其进行铺平，降低了对道路石屑铺设的效率，通过往复丝杠转动使得滑块通过伸缩机构带动横板和刮齿来回滑动，对道路上的石屑进行刮平，便于后续挤压辊对石屑的均匀挤压水平铺设。
