Abstract

The utility model provides a slope screening-clearing machine, which comprises wheels 1, a vehicle frame 2, a control chamber 3, a conveying machine set, a slope digging-storage-transportation machine set 10 and a drive mechanism 14. The utility model is characterized in that a digging bucket wheel frame 23 of the slope digging-storage-transportation machine set is provided with a conveying machine 9 arranged forward above a screen, and a screening machine 7, a conveying machine 5 arranged below the screen and a rotary conveying machine 4 are arranged orderly below the conveying machine 9. The utility model conveys screened dirty earth to the front end of a locomotive so as to keep working positions after the locomotive for a subsequent screening-clearing machine for rod dregs under sleeper or a tamping locomotive, effectively reduces stand-by time, enhances work efficiency by 50 percents, and provides quick and reliable guarantee for the maintenance of railway.

Description

Ballast shoulder cleaning machine

The utility model relates to a kind of railway ballast ballast shoulder cleaning machine, belongs to the railway maintenance engineering truck.

Ballast shoulder cleaning machine is the rail-mounted engineering working vehicle of rail track.On railway line, both can finish railway roadbed side slope cleaning separately, and can unite with cleaner for cleaning under sleeper again railway roadbed is carried out full section cleaning.This machine is when partly carrying out cleaning to the side slope of railway pillow end, and also the ballast that material transport vehicle can be sent here is backfilling in the railway roadbed, thereby its mechanization degree and automaticity are comparatively outstanding.But existing this class railway maintenance machinery, because the dirty soil that sifts out is the conveying device by postposition, with its be sent to the operator on opposite back extension mass transport car, taken very long operation position, the stand-by time of maintenance unit is prolonged, thereby influenced construction speed, therefore, track blockade " skylight " utilization rate is low to be the ubiquitous problem of this class machinery.Be necessary to make improvements.

The purpose of this utility model is to overcome the deficiency of prior art, provides that a kind of to account for the operation position little, and stand-by time is short, the ballast shoulder cleaning machine of high efficiency.

The utility model is realized by following scheme: it comprises running part 1, car body 2, control room 3, carry unit, side slope is excavated accumulating unit 10 and drive unit 14 thereof, it is characterized in that being provided with conveyer 9 on the preposition sieve on the excavating bucket-wheel framework 23 of side slope excavation accumulating unit, the below of this conveyer is provided with preposition screening machine 7, sieve conveyer 5, Rotatruder 4 down successively.Conveyer 9 axially is provided with along car body on the described sieve, its front end is hinged on the relay conveyer 6 by connecting plate 24, pin 18, the rear end is hinged on the excavating bucket-wheel framework 23, form a slope conveyor, and can be with the lifting of excavating accumulating unit 10, and do upper and lower swing around pin joint, so that send in the preposition screening machine 7 with excavating the mixed quarrel of getting up.Described preposition screening machine 7 is located at the below that sieve is gone up conveyer 9 front ends, conveyer 5 is located at the below of this screening machine under the sieve, Rotatruder 4 is located at the sieve below of conveyer 5 front ends down, so that the dirty soil under will sieving is sent on the mass transport car in car body the place ahead through conveyer 5 by Rotatruder 4, perhaps directly throw the railway roadbed both sides, thereby vacate enough operation positions for the postorder locomotive by Rotatruder 4.Be provided with oversize conveyer 15 in the bottom of screening machine rear end in addition, the rear end of this conveyer is provided with backfill bucket 20, so that the ballast backfill that will sieve is near sleeper end of ballast bed and rail.

The utility model compared with prior art has following advantage and effect: owing to be provided with conveyer on the preposition sieve on excavation accumulating unit, and this conveyer can be with the lifting of excavating the accumulating unit on, lower swing, make screening machine, sieve is conveyer down, Rotatruder is prepended to the vehicle frame front end, dirty soil after the screening is sent to the locomotive front end, thereby the working position behind the locomotive is risen fully to ballast screening machine at the bottom of the pillow of postorder or tamping tool supporting operation, reduced the stand-by time of supporting unit, can improve 30% blockade " skylight " utilization rate, for the maintenance of railway provides quick, ensure reliably.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the left view of Fig. 1.

Below in conjunction with accompanying drawing the utility model is described further, is not limited in this but hold within the utility model.

Among the figure, 1 is driving portion, 2 is car body, 3 is the control room, 4 is Rotatruder, can be to track both sides convey materials, 5 are conveyer under the sieve, dirty soil is transported to 4 under the sieve that is used for sifted is branched away, 6 are the relay conveyer, 7 is screening machine, ballast is backfilling into railway roadbed through conveyer 15 by backfill bucket 20 on its sieve that sieves out, 8 is support, be used to support each conveyer, 9 for sieving upward conveyer, its front end is by connecting plate 24, pin 18 is fixedly hinged on the relay conveyer, the rear end is hingedly fixed in excavating bucket-wheel framework 23 by angle bar and pin, on 21 the sliding sleeve, this conveyer is an incline conveyer, and on the lifting of excavating the accumulating unit, lower swing, 10 are side slope excavation accumulating unit, 11 is Excavating bucket, and 12 is horizontal feeder, when the mixing quarrel of having been excavated by Excavating bucket 11 is transported to horizontal feeder 12 tops, automatically after falling into this horizontal feeder, send into sieve again and go up on the conveyer 9, send into screening machine 7 by 9 and sieve, 13 are the guided bearing wheel, 14 for excavating driver, 15 is the oversize conveyer, 16,17 is the feeder of postorder working vehicle, and 19 is receiving hopper, be used for the ballast of postorder working vehicle is filled in the railway roadbed both sides through

backfill bucket

20,21 is lifter, makes side slope excavate accumulating unit 10 along the direction move left and right perpendicular to the vehicle frame longitudinal axis by it, so that excavate the side slope ballast, 22 is hoist, can make on the side slope accumulating unit 10, move down, so that locomotive operation and digging operation, 23 is the excavating bucket-wheel framework.
