Embodiment 2

[0057] With embodiment 1, difference is:

[0058] The water pressure of the cleaning system 7 is set to P / Mpa, the vertical distance from the nozzle to the cleaning position is C / cm, and the horizontal distance is D / cm. The relationship between them satisfies: Among them, ε takes 7.2.

[0059] The gap between the upper mixing drum 512 and the lower mixing drum 511 is 1.2 cm, the wall thickness of the upper mixing drum 512 is 4 cm, the wall thickness of the lower mixing drum 511 is 5 cm, and the inner wall radius of the lower mixing drum is 100 cm.

[0060] When the equipment of this embodiment is applied to a road reconstruction project, the pavement on site is 8m wide, 12cm thick, and 600m in length; After being taken to the road concrete transport mixing device at a speed of 50km per hour and arriving at the operation site within 1 hour, it is quickly debugged and put into production, which is completed within 1 hour; the power unit is started, and an excavator is used to ...

Embodiment 3

[0062] With embodiment 1, the difference is

[0063] The water pressure of the cleaning system 7 is set to P / Mpa, the vertical distance from the nozzle to the cleaning position is C / cm, and the horizontal distance is D / cm. The relationship between them satisfies: Where ε takes 2.

[0064] When the equipment of this embodiment is applied to a certain road reconstruction project, the on-site pavement is 10m wide, 15cm thick, and 400m long; the road concrete transport mixer is about 75km away from the construction site, and the road concrete transport mixer, tractor After being taken to the road concrete transport mixing device at a speed of 50km per hour and arriving at the operation site after 1.5 hours, it was quickly debugged and put into production, which was completed within 1 hour; the power unit was started, and an excavator was used to add raw materials to it, and at the same time , the power device drives the screw to rotate, drives the upper mixing drum 512 to rise, ...

The invention has the advantages of variable stirring volume, adjustable center of gravity, convenient transportation, compact structure, high production efficiency, saving production cost and high degree of automation.

Description

technical field [0001] The invention belongs to the technical field of concrete production equipment, and in particular relates to a road concrete transport mixing device and a using method thereof. Background technique [0002] Since the Shanghai-Jiajia Expressway opened to traffic in 1988 and achieved zero breakthroughs in mainland China's expressways, China's expressway construction has advanced by leaps and bounds. In the first 15 years of expressway development, that is, from 1990 to 2005, expressway construction experienced a period of rapid growth, and the national expressway mileage was growing at a year-on-year growth rate of 20%-80% per year, especially from 1998 to 2005. The average mileage of Xintong Expressway is more than 4,500 kilometers. However, with the rapid development of expressways and the rapid increase in traffic volume, the dynamic load strength, impact force, and fatigue of expressway bridges are constantly increasing, so that the bridge deck is of...
