Problems solved by technology
[0004] The inventors have found that there are at least the following problems in the prior art: in the spiral material distribution trough, the large particle material has a large kinetic energy, and is easy to accumulate on both sides of the material trough after rolling. The large particle material at the flat component floats on the surface of the road along the screed component, forming deep segregation of the road surface

Embodiment Construction
[0039] Combine below Figure 1~Figure 11 The technical solution provided by the present invention is described in more detail.
[0040] Explanation of terms or terms involved in this article.
[0041] Lateral segregation: segregation of the evenly mixed paving medium in the paving width direction of the paver. That is: in the paving width direction, the components (divided by particle size) that make up the paving medium are unevenly distributed.
[0042] Depth segregation: the evenly mixed paving medium segregates in the direction of the paving depth of the paver. Namely: In the direction of paving depth, the components (divided by particle size) that make up the paving medium are unevenly distributed.
[0043] The embodiment of the present invention provides a spiral material distribution system, which includes a material shifting component 1, an ironing component 2 and a material blocking component 3. The shifting component 1 is used for shifting animal feed. The ironing assembl...

The invention discloses a screw distributing system and a paver to optimize the structure of a screw distributing system and relates to the technical field of road construction. The screw distributingsystem comprises a moving assembly, an ironing assembly and a blocking assembly, wherein the moving assembly is used for moving materials; the ironing assembly is arranged near the moving assembly and constructed to iron the materials moved by the moving assembly; the blocking assembly is arranged on one side, facing the moving assembly, of the ironing assembly and constructed into collide materials moved by the collision assembly, so that the materials fall off after collision. According to the technical field, after being moved out of the moving assembly, the materials are firstly thrown onto the blocking assembly and then collided by the blocking assembly to fall off. During collision, movement of the materials is disordered, movement of large materials is more disordered due to inertia, so that falling large materials are in a random distribution state, and the pavement depth separation problem at the ironing assembly is solved.
Description
Technical field [0001] The invention relates to the technical field of road construction, in particular to a spiral material distribution system and a paver. Background technique [0002] Paver is a pavement construction machine used for paving the road base and surface layer. It is widely used in the paving construction of highways, urban highways, rural roads and airport runways. The spiral material distribution system is the core working component of the paver, and its function is to evenly spread the paving media such as cement stabilized concrete or asphalt mixture unloaded from the dump truck on the entire width of the road. The spiral distribution system includes a distribution box, spiral blades, screw shafts, booms, ironing components, front baffles and other structural connections. [0003] In order to reduce the distribution resistance of the spiral material distribution system and improve the anti-segregation ability of the paver, all existing brand pavers adopt spiral...
