The utility model is finished by following technical proposal: a kind of full section excavates screen scarifier, comprises that its below establishes bogie, and the frame of power set and control device is established in the top, it is characterized in that being integrated with successively from front to back on the frame:
The side slope excavating gear---be symmetricly set on the frame both sides and circulation is excavated in perpendicular to the work plane of sleeper section two by the circulation digger chain and be used to contain the side slope excavator that the collection tiny fragments of stone, coal, etc. guide groove of circulation digger chain constitutes, excavate with ballast aggregate the railway roadbed side slope;
Pillow end excavating gear---be arranged on the frame and surround orbit circulation is excavated in perpendicular to the work plane of rail profile by the circulation digger chain and be used to contain and pillow that the collection tiny fragments of stone, coal, etc. guide groove of the circulation digger chain that leads constitutes at the bottom of excavator;
Screen cleaning device---front and back symmetry and squint is arranged to two vibrosieves of V font, side slope of excavating out with efficient screening and pillow end ballast aggregate;
Also be provided with on the frame:
Conveying device---comprise the dirt quarrel conveyer that constitutes by dirt quarrel conveyer belt that is positioned at pillow end excavator discharging opening below and the dirt quarrel conveyer belt that is positioned at side slope excavator discharging opening below, comprise again by the rotation of the dirt conveyer belt that is positioned at the vibrosieve dirt-discherging outlet and dirt and throw the dirt conveyer that band constitutes, also comprise by clean quarrel conveyer belt that is positioned at vibrosieve muck removal mouth and the clean quarrel that is positioned at the frame below and insert the clean quarrel backfill conveyer that conveyer belt constitutes;
Operating room---between pillow end excavator and side slope excavator, and be provided with control device and operating desk in it;
Play the track lining device---on the frame between side slope excavating gear and the pillow end excavating gear, after track being played group built on stilts, reduce pillow end excavating resistance and keep orbital position.
The clean quarrel that is positioned at the frame below of described clean quarrel backfill conveyer is inserted conveyer belt and is provided with two, be symmetricly set on the frame both sides, their feed end joins by the clean quarrel conveyer belt muck removal mouth at hopper and vibrosieve muck removal mouth place respectively, clean quarrel is carried and is brought quarrel into and mouthful join by hopper and vibrosieve muck removal mouth, being cut through hopper on the sieve of bolting only, the conveyer belt that is cut only, hopper, being cut and inserting on the side slope that conveyer belt is backfilled to the railway roadbed both sides only.
Described side slope excavator is the conventional Excavating bucket turbine of prior art, and its excavation depth and width all can be adjusted.
Excavator is the conventional chain type excavator of prior art at the bottom of the described pillow, and its excavation depth and width all can be adjusted.
Described track lining device is the conventional equipment of prior art.
The present invention compared with prior art has following advantage and effect: adopt such scheme, side slope excavating gear by frame front excavates railway roadbed side slope ballast aggregate earlier, cleaning, by excavating gear at the bottom of the pillow at frame rear portion railway roadbed pillow end ballast aggregate is excavated again, cleaning, and clean quarrel behind the cleaning and new quarrel inserted railway roadbed, to sieve the back dirt simultaneously sends, realized the quick of railway ballast full-section broken stone fully, the efficient renewal, fundamentally having solved existing screen scarifier, to be difficult to satisfy rail track because of service behaviour is single high-quality, the requirement of efficient maintenance and maintenance, cause the low problem of rail track " skylight " utilization rate, thereby provide reliable guarantee for the speed-raising of train operation.
