Ironing plate and paver

Abstract

The invention provides an ironing plate which comprises a bottom plate, a heating element and a plate frame body, wherein the plate frame body is covered on the bottom plate, and a heating chamber is defined by the plate frame body and the bottom plate; and the heating element is arranged in the heating chamber. The ironing plate also comprises a heat reflection element arranged in the heating chamber. The ironing plate is internally provided with the heat reflection element, and heat emitted to the heating chamber from the heating element can be reflected to the bottom plate so as to improve the heating speed of the bottom plate. Meanwhile, the bottom plate far away from the heating element is heated by heat reflected by the heat reflection element so as to eliminate the phenomenon that the bottom plate is unevenly heated.

Description

technical field [0001] The invention relates to the field of road maintenance equipment, in particular to a screed and a paver using the screed. Background technique [0002] The asphalt paver will stick to the asphalt material when it comes into contact with the hot asphalt material due to the low temperature of the screed plate at the beginning of the paving or when the interval between two paving is long. When the paver spreads forward, it will pull out the cracks on the asphalt material adhered to the road surface, destroying the smoothness of the road surface, so the screed soleplate is required to have a heating function. At present, the heating methods of the screed mainly include the following: (1) gas heating, using propane gas combustion device to directly heat the screed; (2) electric heating, using an electric heating tube to heat the screed; (3) oil heating, The screed is heated by burning diesel. [0003] Among the above heating methods, the electric heating ...

AI Technical Summary

Problems solved by technology

[0003] Among the above-mentioned heating methods, the electric heating method generally uses the electric heating rod to contact the bottom plate of the screed, so the temperature rise of the bottom plate area close to the heating rod is faster, and the temperature rise of the bottom plate area away from the electric heating rod is slower, resulting in uneven heating of the bottom plate

The gas heating and oil heating methods not only have heat convection with the bottom plate, but also with the surroundings, resulting in serious waste of heat

The above three methods all have the problems of long heating time and uneven heating to varying degrees. Therefore, the construction efficiency is reduced and the construction quality is affected.
