The spraying device of the synchronous gravel sealing vehicle and the synchronous gravel sealing vehicle

Abstract

The invention relates to the field of road construction machinery, and provides a spraying device of a synchronous gravel sealing vehicle and a synchronous gravel sealing vehicle. The spraying device includes a frame and an asphalt storage tank installed on the frame, a gravel bin, an asphalt spraying mechanism and a gravel spreading mechanism. The mechanism includes a first spray pipe, a second spray pipe and a third spray pipe, the first spray pipe and the second spray pipe are located on both sides of the crushed stone spreading mechanism and are used to spray the crushed stone discharged from the crushed stone spreading mechanism; The three spray pipes are located on the same side as the second spray pipe and behind the gravel spreading mechanism for spraying asphalt on the ground. It uses atomized asphalt to spray the crushed stones before contacting the ground, which first makes the connection between the crushed stones stronger and reduces the bouncing of the crushed stones when they fall to the ground. The asphalt and gravel sprayed by the synchronous gravel sealing vehicle have a better bonding effect and are not prone to cracking.

Description

technical field [0001] The invention relates to the field of road construction machinery, in particular to a spraying device of a synchronous gravel sealing vehicle and a synchronous gravel sealing vehicle. Background technique [0002] The synchronous crushed stone sealing vehicle is a special device for asphalt pavement maintenance and maintenance. It concentrates the two processes of asphalt spraying and crushed stone spreading in a short period of time, so that the crushed stone particles can be in contact with the freshly sprayed asphalt immediately. , because the fluidity of the asphalt is better at this time, the gravel can be buried deeper in the asphalt. The connection time between asphalt and gravel is shortened, and the covering area of ​​gravel and asphalt is increased. However, in the prior art, the covering area of ​​asphalt and gravel is not good, which leads to problems such as surface cracking, weak bonding between layers, and falling off of gravel after a ...
