Description

Novel traction type spreading machine

Technical field

The utility model relates to a kind of road base layer spreading machine, particularly is used for the paver that speedway, Class I highway and Ordinary Rd, railway, place basic unit bulk material pave.

Background technology

As everyone knows, in road, railway, place construction and improvement project, paving of base material is a very important job.Base material typically refers to the mixture of building stones, sand, soil, flyash, industrial residue, lime, cement etc. and above-mentioned material, promptly usually said stabilizing material.The laying of base material at present adopts machineries such as bulldozer, loader and land leveller to pave usually.Adopt above-mentioned machinery to pave and have the deficiency of two aspects, the one, operating efficiency is low, and the 2nd, material easily produces segregation.The segregation of material is meant that particle diameter is bigger in the material that is paved building stones can be separated and floats over the top layer or flow to the edge from compound, thereby destroys the grating of material, slackened the supporting capacity of basic unit.

In recent years, China's highway construction project is increasing, mainly based on the standard highway construction, as Class I highway, speedway etc., these highway widths are big, and construction engineering units is to the quality requirement height, the shaping that once paves of stabilized zone requirement full width or half range paves, owing to lack large-scale Stabilized Soil paver special tool, unit in charge of construction or adopt large-scale asphalt paver to pave perhaps adopts the logical paver of two Daeporis to pave together.When adopting asphalt paver, require the asphalt paver specification many more than 1Bm, this mechanical price is comparatively expensive, and when paving the above width of 7m, because machine power deficiency, segregation phenomenon is serious, and the planeness that both sides pave is significantly wavy because of housing rigidity Xiao Yi produces, and has reduced the credit rating of road.If unit in charge of construction adopts two pavers to unite and paves, there is seam in the road that paves, make road quality be difficult to control, and use two pavers not only purchase cost be double, the loss that causes when wear and tear in machines also is double, makes the engineering cost of unit in charge of construction effectively to reduce.And existing paver all is to adopt hydraulic cylinder or mechanical engine as power source, and hydraulic cylinder equipment price costliness can't reduce the engineering cost of Construction unit.

Summary of the invention

The purpose of this utility model provides a kind of low cost and effectively guarantees the novel traction type spreading machine of planeness.

To achieve these goals, the novel traction type spreading machine that the utility model provides comprises: forebay, afer bay, feeding-distribution device, drive unit, spreading plate, bracing or strutting arrangement, levelling device, draw-gear, frame connector and levelling sensor; Wherein, the pushing tow roller is located at the forebay front end; The pushing tow pair of rollers is answered a dump truck inlet orifice; Afer bay is provided with to the linking arm that protracts, be used to connect described afer bay and described forebay; Spreading plate is located at the afer bay forward position; Feeding-distribution device is located at the place ahead of spreading plate; On afer bay, be provided with bracing or strutting arrangement; Drive unit is a power-jdriven gear; Be provided with hydro-leveling device between the linking arm of bracing or strutting arrangement and afer bay.

Further, forebay comprises left front frame and right front frame, and afer bay comprises left back frame and right back frame; The pushing tow roller is located at left front frame and right front frame front end respectively; Every group of respectively corresponding dump truck inlet orifice of pushing tow roller; Inlet orifice corresponding left and right respectively each forebay and afer bay; Draw-gear is located on the forebay; Connect by the frame connector between the left and right frame, the frame connector is the link that is arranged between left back frame and the right back frame.

Further, forebay comprises left front frame and right front frame, and afer bay comprises left back frame and right back frame; The pushing tow roller is located at left front frame and right front frame front end respectively; Every group of respectively corresponding dump truck inlet orifice of pushing tow roller; Inlet orifice corresponding left and right respectively each forebay and afer bay; Connect by the frame connector between the forward and backward frame of left and right part, the frame connector is the link that is arranged between left back frame and the right back frame; Afer bay is provided with draw-gear.
