Roadbed soil filling and flattening device

Abstract

The invention discloses a roadbed soil filling and flattening device. The upper end of a driving motor is rotationally connected with a driving shaft. A driving shaft bearing is rotationally connectedwith a transmission case. The top of the driving shaft is in rolling connection with the left end of a conveying belt. The right end of the conveying belt is in rolling connection with the upper endof a stirring shaft. A bearing on the upper portion of the stirring shaft is rotationally connected with a material storage barrel. The lower end of the stirring shaft is fixedly connected with a turnplate. The turnplate is rotationally connected with the inner wall of the material storage barrel. A material guide pipe is arranged on the turnplate in the peripheral direction. The lower end of thematerial guide pipe abuts against the bottom of the material storage barrel. The lower portion of the driving shaft is fixedly connected with a first bevel gear. A second bevel gear is fixedly connected with the right end of a bidirectional lead screw. According to the roadbed soil filling and flattening device, the conveying belt drives the stirring shaft to rotate, accordingly, stirring rods aredriven to rotate so as to stir crushed soil in the material storage barrel, the crushed soil is prevented from caking, the rotating stirring shaft drives the turnplate to rotate so as to drive the material guide pipe to rotate to be reciprocatively aligned with a discharging pipe, intermittent discharging is achieved, meanwhile, moving blocks moving left and right drive oscillating rods to oscillate reciprocatively, and accordingly, rolling wheels are driven to perform rolling compaction on the ground reciprocatively and to planish the crushed soil discharged out of the discharging pipe

Description

technical field [0001] The invention relates to a road construction machine, in particular to a roadbed pad soil flattening device. Background technique [0002] Subgrade refers to the belt-shaped structure built according to the location of the route and certain technical requirements as the foundation of the road surface. It is the foundation of railways and highways. The subgrade is a linear structure built with soil or stone. The subgrade built under good geological, hydrological and climatic conditions. In terms of materials, roadbeds can be divided into three types: soil roadbeds, stone roadbeds, and earth-rock roadbeds. The subgrade body includes the embankment filled with natural soil and stone and the cutting dug out of the natural stratum, which directly supports the track and bears the load of the train passing through the track, and is the main body of the subgrade.

AI Technical Summary

Problems solved by technology

[0003] Before the roadbed is leveled, it is often necessary to pad and flatten the uneven parts of the roadbed. Most of the existing roadbed constructions are filled with soil and then flattened. The work efficiency is not high, the degree of automation is low, and a large amount of labor is required.
