Description

Spreading equipment Technical Field The invention relates to the technical field of road engineering, in particular to paving equipment. Background The novel modified polyurethane mixture needs to be synchronously mixed with glass fibers to enhance the tensile strength between layers during paving, and small particle stones are immediately scattered after the paving is finished to form a wearing layer. Because of the characteristic of extremely high solidification speed of the modified polyurethane, each construction process needs to be connected quickly. The conventional paver lacks an integrated fiber adding mechanism and a synchronous facing sand spreading system, cannot meet the special process requirements, and at present, the polyurethane mixture paving operation mainly depends on the conventional asphalt paver to be combined with manual assistance or partial improvement equipment, and has the problems of poor cooperativity, low efficiency, high labor cost and the like. The utility model patent in China with the application number 202120880627.6 discloses a spreading-paving integrated device for a synchronous vehicle, which comprises an asphalt tank, a fiber bin and a broken stone bin which are arranged on a moving platform, wherein a first nozzle communicated with the asphalt tank and a second nozzle communicated with the fiber bin are arranged at the bottom of the moving platform, a discharging pipe communicated with the broken stone bin is further arranged at the tail of the moving platform, and asphalt binder, glass fiber and broken stone surface sand can be spread on a newly-built road base layer at the same time. The asphalt paving is used as an application background, and the asphalt paving machine is also suitable for paving polyurethane mixtures to a certain extent. However, the device has two obvious defects that firstly, glass fibers are paved above a pavement in a spreading mode instead of an internal blending process required by polyurethane mixture, and secondly, the device does not integrate a vibration leveling structure, and other equipment is needed to be relied on for leveling after spreading. In view of the characteristic of rapid solidification of the modified polyurethane mixture, the ideal paving equipment can synchronously finish paving and leveling operation. In addition, the optimal leveling should be performed after the glass fiber is paved and doped and before the facing sand is spread, and the device disclosed in the patent cannot meet the strict process timing requirement even though other devices are used for leveling later. Disclosure of Invention The technical problem to be solved by the invention is to provide a paving device integrating polyurethane mixture paving vibration level and synchronously blending glass fibers. The technical scheme adopted for solving the technical problems is as follows: A paving apparatus comprising A frame; the walking structure is arranged at the lower part of the rack and used for driving the rack to move; The paving assembly is arranged on the frame; The novel glass fiber paving machine is characterized in that the paving component comprises a stirring and distributing structure, wherein the stirring and distributing structure is provided with a first discharge port and a third discharge port for paving polyurethane mixture and a second discharge port for discharging glass fiber; The first discharge port, the second discharge port and the third discharge port are arranged at intervals in the front-back direction of the travelling direction of the frame, so that when the paving equipment travels, glass fibers scattered from the second discharge port fall on a bottom polyurethane mixture pavement paved from the first discharge port and are covered by an upper polyurethane mixture pavement paved from the third discharge port, and the glass fibers are mixed between the two polyurethane mixture pavement layers. Compared with the prior art, the polyurethane mixture is discharged from the first discharge port, the bottom polyurethane mixture layer is formed in the advancing direction, the glass fiber is discharged from the second discharge port and uniformly spread on the bottom polyurethane mixture just paved, then the polyurethane mixture is discharged from the third discharge port and covers the glass fiber, so that the glass fiber is embedded between the two layers of polyurethane mixtures, and synchronous mixing of the glass fiber is realized. According to the invention, through integrated continuous operation, the paving of the polyurethane mixture and the blending of glass fibers are completed at one time, so that the difficult problems of unsmooth connection and coordination in the traditional multi-equipment step construction are fundamentally avoided, the construction efficiency and interlayer bonding quality are greatly improved, and the glass fibers are ensured to be embedded into the polyurethane mixture timely and uniformly.
