Efficient sandy soil screening equipment for road and bridge construction

Abstract

The invention provides efficient sandy soil screening equipment for road and bridge construction. The efficient sandy soil screening equipment for road and bridge construction comprises a filtering box, a stirring box, a motion control box and a power box, the bottom of the filtering box is in contact communication with the top of the stirring box, a timing controller is arranged on the front side face of the stirring box, the motion control box is fixed to the bottom of the stirring box, the power box is fixed to the bottom of the motion control box, a hinged shaft is arranged at the top of the filtering box, the right portion of the hinged shaft is connected with the left end of a cover plate, an electric cylinder bottom plate is fixed to the right side face in the filtering box, an electric cylinder is fixed to the left side face of the electric cylinder bottom plate, an action rod is arranged at the left power output end of the electric cylinder, an action longitudinal arm is fixed to the left end of the action rod, and an upper transverse arm and a lower transverse arm are fixed to the upper end and the lower end of the action longitudinal arm respectively. According to the technical scheme, the technical problems that in the prior art, crushing and screening capacity is not achieved, intermittent stirring and flexible moving and transporting cannot be achieved are effectively solved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a high-efficiency screening device for sand and soil used in road and bridge construction. Background technique [0002] Road bridges are generally composed of several parts such as roadbed, road surface, bridge, tunnel engineering and traffic engineering facilities. With the vigorous development of the transportation industry, the number of high-grade highways mainly including expressways and first-class highways has increased year by year, and my country's highway industry has entered a new stage focusing on the construction of high-grade highways. Sandy soil for road and bridge construction refers to the soil mixed with more than 80% sand and less than 20% clay. Generally refers to the soil with a lot of sand. This kind of soil is loose and has good water permeability and air permeability, but its ability to retain water and fertilizer is poor, so it nee...
