Description

Technical Field

[0001] The utility model relates to the technical field of asphalt distributors, in particular to a hydrogen fuel cell asphalt distributor. Background Art

[0002] Asphalt spreaders are essential equipment in highway maintenance. There are currently two power sources for driving thermal oil pumps and asphalt pumps:

[0003] One approach involves installing an auxiliary engine to drive a hydraulic pump, which in turn drives a hydraulic motor, which in turn operates the thermal oil pump and asphalt pump connected to the motor. While this method can meet the operational requirements of asphalt distributors, the specific nature of the equipment makes it difficult to regulate the emissions requirements of auxiliary engines. Consequently, many manufacturers use auxiliary engines that do not meet national emission standards, resulting in significant air pollution during use.

[0004] The second method is to install a power take-off on the main vehicle engine, and rely on the main vehicle engine to do work to drive the hydraulic pump, and then the hydraulic pump drives the hydraulic motor to drive the thermal oil pump and asphalt pump. Although this method solves the problem of air pollution, it will greatly reduce the power of the main vehicle engine used to drive the vehicle forward, resulting in insufficient power when the vehicle is driving, especially when the vehicle is climbing a slope, and may also cause safety accidents.

It should be noted that the asphalt pump 701 is also provided with an asphalt flow inlet, which is connected to the asphalt storage module 5. Alternatively, an asphalt heating tank is provided between the asphalt storage module 5 and the asphalt flow inlet.
