Description

Spreading machine

Technical Field

The utility model relates to the field of construction of engineering machinery, in particular to a paver.

Background

The paver is one of the important engineering machines in the construction of the highway, bridge road at present, because pave, jolt ramming, many functions such as levelling to the road surface are integrated, raise the efficiency that the construction road surface paves greatly, improve the quality of the road surface of mating formation, can be fine to guarantee its stability of quality at the same time, and greatly reduced the construction cost of road surface mating formation. The existing concrete is primarily distributed by a distributing device or an excavator before paving, namely raw materials are pre-distributed on a route where a paver passes, the concrete to be paved in front of the paver is required to be distributed as uniformly as possible, and the mixture in front of the paver is uniformly mixed by a spiral distributing device or a distributing plough. Pavers of different specifications can only pave pavements of corresponding widths. Therefore, construction units need to purchase various devices with different specifications for road construction with different widths, the cost of purchasing the devices and the cost of maintenance of the construction units are increased greatly, the transition utilization rate is not improved, and the construction progress of roads is seriously influenced.

Chinese utility model patent that is cn200920245285.x for this patent number just discloses "a novel paver spiral feed divider", this feed divider passes through the straight-tooth spiral reduction gear transmission power that sets up spiral distributor outer end both sides about, extension spiral passes through the spline hookup with left and right spiral distributor simultaneously, conveniently change extension spiral, can be no longer than the regulation width scope that paves, according to the change of the road surface width that paves, make up extension spiral wantonly, and control the motor support and can freely stretch out and draw back, make the assembly easy and highly regulated convenient. Although the material distributing device realizes the general distribution and distribution of the road surfaces with different widths by replacing the lengthened screw, the subsequent processes such as vibration and trowelling and the like can only operate partial distributed materials due to the layout design of the whole machine, so that the whole road surface pavement can be completed by repeating the subsequent processes for multiple times although the width adjustment of the material distribution is realized, and the whole road surface pavement is very complicated.

For example, chinese utility model patent No. CN201821726134.1 discloses a full width slip form cement concrete paver, in which, the whole working mechanism is moved to the rear side of the frame by a cantilever formed by extending the rear side of the frame, so that the working mechanism for vibration leveling can complete the width adjustment in pavement paving at one time, which is very convenient, but the distance for conveying the whole raw material is increased due to the design of moving the whole mechanism backward, and it is difficult to form a uniform feeding speed due to different concrete thickness, and once the feeding part is conveyed too fast, the concrete raw material will fly to the rear side of the auger due to inertia, resulting in uneven mixing; and when the feeding is too slow, the partial area after the spreading and compaction is uneven due to the lack of the material and the leakage of the material.

There is therefore a need for further improvements in such pavers.
