Description

Paver with improved rotary mechanism Technical Field A paver with an improved revolving mechanism is used for paving a road surface and belongs to the technical field of pavers. Background In pavement construction, the mixture is uniformly paved on the required width according to the specified loose pavement thickness. The cement stabilized macadam foundation layer is paved by an asphalt concrete paver or a special stabilized soil paver, and the paver has the performances of automatic leveling, whole paving, larger paving thickness, automatic control of operation speed and feeding speed and high pre-compaction degree. The water content of the mixture during paving is preferably 0.5% -1.0% higher than the optimal water content to compensate for water loss during paving and rolling. The spiral distributor is one of core components of the paver, and the mixture is transversely conveyed from the middle trough to the width direction of paving through the rotary motion of the spiral blades, so that the mixture is uniformly distributed. The concrete working principle is that the helical blade rotates under the drive of the driving device to push the mixture to move along the axial direction (the spreading width direction). However, the helical blade in the prior art has the following technical problems: 1. The thickness of the helical blade is too thick, so that the contact area with the mixture is too large, the segregation risk is increased, the energy consumption is increased, and the problem of abrasion resistance reduction is easily caused due to the too thin thickness; 2. The mixture is rolled by a road roller after being paved, the temperature of the mixture is easy to drop after the mixture is not rolled immediately after being paved, so that the uniform compaction effect is affected, and meanwhile, the construction efficiency is reduced; 3. The bottom of the front analysis baffle in the spiral distributor can not effectively block the sliding materials in the conveying process of the spiral blades, so that the problem that the paving thickness is difficult to quickly reach the requirement is easily caused.
