Embodiment 1

[0022] see figure 1 with figure 2 , a spiral blade of a paver, comprising a blade body 1 and a connecting body 2 arranged on one side of the blade body. In this embodiment, the blade body 1 and the connecting body 2 are cast as one piece. The connecting body 2 is in the shape of a bearing bush. The connecting body 2 is provided with holes for installing locking bolts.

[0023] The blade body 1 includes a back surface and a material guiding surface opposite to the back surface. The material guide surface is the surface in the same direction as the material conveying direction, and is the action surface between the blade body 1 and the material. The grid-like ribs 3 are arranged on the material guiding surface, and the grid-like ribs 3 form several grooves 4 on the material guiding surface. In this embodiment, the grid-like ribs 3 and the blade body 1 are integrally cast. The transition between the grid-like ribs 3 and the material-guiding surface of the blade body 1 adop...

Embodiment 2

[0027] A paver equipped with any one of the above-mentioned helical blades. That is, the paver has a rotatable paving shaft. A plurality of said helical blades are fixedly installed on the paving rotating shaft by screws, and the helical blades form helical blades from one end of the paving rotating shaft to the other end.

Abstract

The invention discloses a paver spiral blade and a paver and belongs to the technical field of road construction devices. The paver spiral blade comprises a blade body and a connecting body arranged on one side of the blade body, and the blade body comprises a back surface and a material guide surface opposite to the back surface. A latticed rib body is arranged on the material guide surface, anda plurality of grooves are formed on the material guide surface by the latticed rib body. The spiral blade is light in weight, resistant to abrasion and high in conveying efficiency.

Description

technical field [0001] The invention belongs to the technical field of road construction equipment, and in particular relates to a paver spiral blade and a paver. Background technique [0002] In the construction and maintenance of highways and urban roads, asphalt or concrete pavers have been widely used at home and abroad to pave asphalt or concrete on the road surface. The screw distributor is a key part of the material flow during the construction of the paver, and the screw blade is also a key component used to transport the viscous and compressible materials on the screw distributor. At the same time, it has and completes the functions of stirring and mixing materials. [0003] The existing spiral blade of paver mainly includes a casing as a connecting body and a blade body surrounding the casing and having a certain helical angle. The sleeve body drives the blade body to rotate. The surface of the blade body extruding the material is the material guide surface, the ...
