Asphalt hot material mixing machine

Abstract

The invention relates to an asphalt hot material mixing machine which comprises a mixing bucket (1) with an opening (11), and a rack (2). The asphalt hot material mixing machine is characterized by also comprising a heater (3), a power device (4) and a transmission device, wherein the mixing bucket (1) is arranged on bearing rollers (6) on the rack (2); the heater (3) is arranged below the mixing bucket (1); the mixing bucket (1) is connected with the power device (4) and is driven to rotate through the transmission device; the mixing bucket (1) is internally provided with continuous spiral stirring blades (10). The asphalt hot material mixing machine is reasonable in structure, simple to operate, convenient to use, high in practicability, and high in effect, saves energy, is environmentally friendly, and wide in application.

Description

technical field [0001] The invention relates to road surface maintenance machinery, in particular to an asphalt hot material mixer. Background technique [0002] In the rapid development of transportation, highways, as the carrier of transportation, need to be maintained for a long time in order to maintain a good state, and road surface maintenance is the key. Among them, asphalt pavement is the most widely used high-grade pavement in road construction. For the maintenance of asphalt pavement, the emphasis is on fast, efficient and smooth flow. At present, there are many disadvantages in the maintenance methods usually used for repairing potholes on asphalt pavement: [0003] (1) Cold material repair method: the effect is high, but the chemical properties of the cold material determine that the quality of the repaired road surface is poor, it will be damaged when it rains, the durability is poor, repeated repairs, waste of manpower, material and financial resources; and i...

Problems solved by technology

[0003] (1) Cold material repair method: the effect is high, but the chemical properties of the cold material determine that the quality of the repaired road surface is poor, it will be damaged when it rains, the durability is poor, repeated repairs, waste of manpower, material and financial resources; and it cannot be repaired in a large area;

[0004] (2) Mixing station processing method: many links, large waste, not environmentally friendly, and high cost; hot asphalt mixture is used for repairs, because road maintenance "more points and less quantity", hot asphalt mixture production costs (mixing start-up costs, heating up Due to the long construction time and the gradual drop in temperature, 60-80% of the hot asphalt mixture cannot be used, which is too wasteful and costly; moreover, the disposal of excess asphalt mixture is also a kind of environmental hazard. Pollution;

[0006] ①. There are many components in each part, and its own volume is large, which is not convenient for transportation;

[0007] ②. The technological process is relatively complicated, the energy conversion loss is large, and the energy saving is poor;

[0008] ③. The cold mixing tank is easy to absorb or leave asphalt mixture, which makes the machine unusable;

[0009] ④, the manufacturing cost is too high, and the input and output do not match; the structure of this type of machine is relatively complicated, the components are also relatively bulky and thick, and the configuration of heating, lifting, transmission, mixing, hydraulic pressure, etc. is too complicated, so the manufacturing cost is high and the price is expensive , integrated with the car, the price is around 300,000 to 400,000 yuan;

[0010] ⑤. Thermal regeneration of asphalt mixture cannot be carried out
