Problems solved by technology
These three methods all have the problems of long heating time and uneven heating to varying degrees. At the same time, they cannot guarantee the constant temperature of the asphalt paver screed, resulting in too slow temperature rise of the screed, large temperature difference, sometimes underheating, sometimes Overheating, local deformation, etc., will cause quality problems in the paved asphalt pavement
On the other hand, the consumption of electricity and gas is relatively large, and resources are wasted

Embodiment Construction
[0009] The intelligent heating device for asphalt paver screed of the present invention includes a multi-section screed, and the section of each section of the screed is as follows: figure 1 As shown, it includes a cover body 1 and a bottom plate 2, and a burner nozzle 3 is arranged above the bottom plate in the cover body, and the burner nozzle is controlled by a combustion control system. A far-infrared radiation layer 4 made of a far-infrared radiation material is arranged between the burner nozzle and the bottom plate. A control needle 5 for detecting temperature is installed near the burner nozzle, and a temperature sensor 6 is arranged between the far-infrared radiation layer and the bottom plate.
[0010] Such as figure 2 As shown, the combustion control system includes a gas pipeline connected between the gas outlet and the burner nozzle 3. A manual gate valve 7 is installed at the beginning of the gas pipeline, and a pressure regulating valve 8 is installed behind t...

The present invention belongs to the field of road engineering machinery, and is especially one kind of intelligent heater for ironing plate of asphalt spreader. The intelligent heater includes several ironing plates comprising one cover and one bottom plate inside the cover each, burner nozzles controlled with the combustion control system and set over the bottom plates, and one far infrared radiation layer made of far infrared radiating material set between the nozzle and the bottom. The intelligent heater has high temperature raising speed, homogeneous temperature, high heat efficiency and capacity of resulting in high asphalt spreading quality.
Description
technical field [0001] The invention belongs to road construction machinery and relates to an intelligent heating device for screed plates of asphalt paver machines. Background technique [0002] The existing asphalt paver screed heating methods mainly include the following: (1) The screed is directly heated by a propane gas combustion device. The gas is ignited by the cylinder to heat the screed after passing through the pressure reducing valve, switch, pipeline and nozzle. (2) The electric heating tube is used to heat the screed. It is composed of a generator, electrical control, wiring, heating devices, etc. to achieve the purpose of heating the screed. (3) The screed is heated by burning diesel. The diesel oil passes through the fuel pump group, the pipeline, the burner and is ignited by electrical appliances to heat the screed. These three methods all have the problems of long heating time and uneven heating to varying degrees. At the same time, they cannot guarante...
