Embodiment Construction

[0038] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0039] figure 2 Shown is a schematic structural diagram of a screed surface heater according to an embodiment of the present invention. image 3 Yes figure 2 An enlarged view of area A in the embodiment shown. The screed surface heater of this embodiment includes an ejector pipe 1, a mesh surface 3 and a heat insulation surface 6. The mesh surface 3 is arranged below the heat insulation surface 6, and the mesh surface 3 and the heat insulation surface 6 enclose a gas mixing cavity 2. The ejector tube 1 is in communication with the gas mixing chamber 2, and the gas can burn on the mesh surface 3.

[0040] The ejector tube 1 can be directly installed on the gas mixing chamber 2. Prefe...

Abstract

The invention discloses a paving machine and a screed surface heater thereof. The screed surface heater includes an ejector pipe, a mesh surface and a heat insulation surface, the mesh surface is arranged below the heat insulation surface, and the mesh surface and the heat insulation surface enclose a gas mixing chamber, so The injection tube communicates with the gas mixing chamber, and the gas can be burned on the mesh surface. There are at least two areas with different air permeability on the mesh surface, and the air permeability of the area away from the injection tube is greater than that of the adjacent injection tube. The breathability of the area. The invention can ensure that the mixed gas is supplied evenly on the mesh surface, and has good combustion stability and temperature uniformity. The invention can also reduce the overall thickness, increase the installation space and improve the maintainability.

Description

Technical field [0001] The present invention mainly relates to the technical field of road construction machinery, in particular, to a screed surface heater of a paver and a paver provided with the screed surface heater. Background technique [0002] In order to prevent roughening during the construction of the asphalt pavement, the paver must preheat the bottom plate of its screed before each paving. [0003] At present, there is a method of heating the screed by using a surface heater. figure 1 Shown is a structural diagram of a surface heater of a prior art paver. The surface heater is placed in the screed cavity 6'and above the bottom plate 5'of the screed. The surface heater is mainly composed of a shell 2', a heat insulation surface 7', a mesh surface 3', an ejector tube 1'and a gas distribution cover 4'. [0004] Among them, the gas distribution cover 4'is generally a polyhedron, with small holes of different sparseness on each surface, and the mesh surface 3'is formed by sup...
