Vibration stirrer special for construction of large-particle-size drainage bituminous stabilized macadam base layer

Abstract

The invention relates to a vibration stirrer special for construction of a large-particle-size drainage bituminous stabilized macadam base layer. The vibration stirrer comprises a spiral conveyor; theouter side of the spiral conveyor is sequentially provided with a washing bin, a drying bin, a mixing bin and a mixture treating bin from left to right; first steel wire cages are arranged between the washing bin and the spiral conveyor as well as between the drying bin and the spiral conveyor correspondingly; a second steel wire cage is arranged between the mixing bin and the spiral conveyor; athird steel wire cage is arranged between the mixture treating bin and the spiral conveyor; nozzles and a water outlet are formed in the washing bin, and the nozzles are connected with a water pump through pipelines; a heating device is arranged in the drying bin; a stirring shaft is arranged in the mixing bin and connected with stirring blades; a bituminous binder outlet is formed in the lower part of the mixture treating bin and connected to a bituminous binder storage tank through a pipeline; and a horizontal vibrator and a vertical vibrator are arranged in the mixing bin and the mixture treating bin correspondingly. The vibration stirrer has the advantages that performance is stable, the cost is low, the stirring effect is good, and materials are saved.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a special vibrating mixer for the construction of a large-diameter drainage asphalt stabilized gravel base. Background technique [0002] Cement-stabilized macadam base is a main pavement structure form of highways in my country. There are many cracks, no drainage, and sensitivity to axle load in cement-stabilized macadam base. Due to the large-size drainage asphalt-stabilized macadam base, reflection cracks can be suppressed. , drainage, ventilation, insensitivity to axle load, long service life, easy maintenance, etc., have been widely used in China recently. In order to achieve a void ratio of 18%-25%, the large-size drainage asphalt stabilized gravel mixture is mainly made of large bone In order to ensure a large void ratio, it is necessary to reduce the amount of asphalt as much as possible, and the thickness of the oil film should be small rather tha...

[0002] Cement-stabilized macadam base is a main pavement structure form of highways in my country. There are many cracks, no drainage, and sensitivity to axle load in cement-stabilized macadam base. Due to the large-size drainage asphalt-stabilized macadam base, reflection cracks can be suppressed. , drainage, ventilation, insensitivity to axle load, long service life, easy maintenance, etc., have been widely used in China recently. In order to achieve a void ratio of 18%-25%, the large-size drainage asphalt stabilized gravel mixture is mainly made of large bone In order to ensure a large void ratio, it is necessary to reduce the amount of asphalt as much as possible, and the thickness of the oil film should be small rather than large. However, the large-size drainage asphalt stabilized gravel mixture is mixed with an ordinary mixer, and the asphalt ratio is not easy to control. Therefore, it is very important to provide a special vibrating mixer for the construction of large particle size drainage asphalt stabilized gravel base with simple structure, stable performance, low cost, good mixing effect and material saving.
