Problems solved by technology

[0003] The existing roadbed material mixing device has an unsatisfactory mixing effect on the raw materials used in the roadbed. The mixing method is single, the mixing time is long, and the mixing is uneven, which leads to secondary processing of the roadbed materials and reduces work efficiency. Therefore, we A material mixing device for roadbed construction is proposed to solve the problems raised in the above-mentioned background technology

Abstract

The invention discloses a material mixing device for roadbed construction, and relates to the technical field of roadbed construction. The material mixing device for roadbed construction comprises a mixing box, a first stirring device is installed in the mixing box, the first stirring device comprises a motor, the motor is arranged on the outer wall of the bottom of the mixing box, and the bottom of the inner wall of the mixing box is rotationally connected with a main gear; and auxiliary gears are rotationally connected to the bottom of the inner wall of the mixing box and are positioned on two sides of the main gear. The materials are driven by a spiral stirring paddle to move downwards, and meanwhile, a stirring pipe is tubular and the middle of the stirring pipe is hollow, so that the materials gather towards the center of the stirring pipe, fall to the bottom of the mixing box through the stirring pipe, flow out of the stirring pipe through a discharging pipe, and are dispersed towards the two sides through the spiral discharging paddle; meanwhile, a part of the materials flow out of the stirring pipe through a discharging port, the materials are conveyed upwards through the spiral stirring paddle, the materials are conveyed downwards through the stirring pipe, and the materials are mixed more evenly through cooperation of the upper stirring paddle and the lower stirring paddle.

Description

technical field [0001] The invention relates to the technical field of roadbed construction, in particular to a material mixing device for roadbed construction. Background technique [0002] The subgrade is the foundation of the track or road surface, and it is a geotechnical structure formed after excavation or filling. The main function of the subgrade is to provide the necessary conditions for the laying of the track or road surface and the operation of trains or trains, and to bear the static and dynamic loads of the track and rolling stock or the road surface and traffic loads, and at the same time transfer and spread the load to the depth of the foundation. On the longitudinal section, the roadbed must ensure the elevation required by the line; on the plane, the roadbed is connected with bridges and tunnels to form a complete and continuous line. In civil engineering, subgrade plays an important role in terms of construction quantity, floor area and investment. The s...
