For make multiple scraper plates can not the clear of spacing scrape spreading tube overall length, the half Zhou Chang great of the spool 8
In equal to the spacing between two neighboring scraper plate.
It is toothed around on 9 periphery of drive disk, for gear teeth meshing there are one gear 21, gear 21 is connected with driving dress
Put 22.
For the present invention when specifically used, the feed inlet of two spreading tubes is connected to asphalt tank and water tank through bitumen pipeline, drip
The pitch melted in blue or green tank equipped with heat, water tank is interior to be equipped with water;14 both ends of steel wire rope are wrapped on two spools 8 always in drawing
Tight state, when driving device 22 is not actuated, two blocks and two drive blocks are respectively positioned on the upper quadrant of each autokinesis Circular test
At point;When spraying pitch, start the bitumenpump on bitumen pipeline first, then each switch valve on control piper makes pitch exist
Xun Huan preheats spraying pipeline in pipeline.
After the completion of preheating, controlling switch valve makes to form access between asphalt tank and spreading tube, and the pitch in asphalt tank is dripping
The first spreading tube 1 and the second spread are respectively enterd by first charging aperture 3 and second charging aperture 4 through bitumen pipeline under the action of green grass or young crops pump
Pipe 2, then sprayed through the nozzle 5 on spreading tube;Due to along spreading tube pipe range direction there are pressure drop, so close to feed inlet nozzle
5 pitches ejection pressure is larger, and 5 pitch of the nozzle ejection pressure away from feed inlet is smaller, this results in single spreading tube along pipe range
Direction pitch sprinkling is uneven, i.e. 1 left end asphalt distribution amount of the first spreading tube is more than right end asphalt distribution amount, and the second spreading tube 2 is right
Asphalt distribution amount is held to be more than left end asphalt distribution amount;At same position on left and right directions, the pressure of 1 upper nozzle 5 of the first spreading tube
The pressure drop being reduced on the 5 left side spread length of tube of nozzle, the pressure drop of 2 upper nozzle 5 of the second spreading tube is the 5 right side spreading tube of nozzle
Pressure drop in length, the pressure drop of 1 upper nozzle 5 of the first spreading tube are just spreading tube plus the pressure drop of 2 upper nozzle 5 of the second spreading tube
Pressure drop in overall length length, i.e., in any position, the overall presure drop of two nozzles 5 on two spreading tubes is identical namely any bit
It is identical to put the asphalt distribution amount summation of two nozzles 5, the first spreading tube 1 of the invention carries out first pass sprinkling preceding, and second spills
Stringing 2 carries out second time sprinkling rear, and after twice of sprinkling, the asphalt distribution amount of any position is sprayed for two spreading tube upper nozzles 5
Spill the summation of pitch, i.e., it is identical everywhere, realize uniform sprinkling of the pitch along pipe range direction.
Further, since the gap trend between the rubble completed is extremely irregular, if a direction sprinkling pitch, for walking
To the gap opposite with sprinkling direction, pitch cannot directly be poured into gap, can only be penetrated by flowing in gap, this just leads
Cause such gap exist cannot effective injection pitch possibility, formation weak spot, in the future road surface may using such weak spot as
Center starts to burst bad;Nozzle 5 on first spreading tube 1 of the invention tilts backwards sprinkling pitch, the nozzle 5 on the second spreading tube 2
Turn forward sprinkling pitch, can ensure that pitch is directly poured into gap, makes gap to the greatest extent from both direction sprinkling
Filling is more effective.
After the completion of sprinkling, the access between asphalt tank and spreading tube is closed, bitumenpump reruns a period of time, makes pipeline
Interior remaining pitch empties, and pipeline then is switched to water tank, makes to form access between water tank and spreading tube, then unscrews first
The end cap 15 at 1 and second spreading tube of spreading tube, 2 both ends, the taper flaring 18 at spreading tube nozzle no longer squeeze conical seal ring
17, the second cord hole 19 on conical seal ring 17 unclamps steel wire rope 14, allows steel wire rope 14 in the first cord hole 16 and the second rope
It is free to slide in hole 19, while start driving device 22;In initial position, two blocks and two drive blocks are respectively positioned on each
At the upper quadrant point for moving Circular test, since the spool 8 and drive disk 9 in front are eccentric and axis is located on 9 axis of drive disk
Side, therefore, the movement Circular test of the first block 10 and the movement Circular test of the first drive block 12 are on it at quadrantal points at a distance of most
Far, i.e., the radial distance of the first block 10 and the first drive block 12 is farthest at this time, at this time the outside and first of the first drive block 12
The inside of block 10 is mutually neat, and the first drive block 12, which rotates, can just cross the first block 10 without driving its rotation;On the contrary, by
Spool 8 and drive disk 9 in rear be eccentric and axis is located at 9 axis of drive disk lower section, therefore second is driven at upper quadrant point
The radial distance of 13 and second block 11 of motion block is nearest, at this time the outside phase of the outside of the second drive block 13 and the second block 11
Together, i.e. the second drive block 13 and the fitting of the second block 11 can promote the second block 11 to rotate;After starting driving device 22 at this time, drive
Dynamic device 22 drives drive disk 9 to rotate by gear 21, after drive disk 9 promotes the second block 11 to drive by the second drive block 13
The spool 8 of side rotates counterclockwise beginning take-up, while steel wire rope 14 pulls the spool 8 in front to rotate clockwise unwrapping wire, steel
For 14 tail end take-up head end unwrapping wire of cord so as to pull steel wire rope 14, steel wire rope 14 drives multiple first scraper plates 6 thereon to transport to the right
Dynamic, multiple second scraper plates 7 are to left movement, and the first scraper plate 6 and the second scraper plate 7 are respectively to the second spreading tube 2 of the first spreading tube 1
Inner wall is scraped clearly, and the pitch adhered to thereon is struck off, while the water in water tank is pumped into two spreading tubes by bitumenpump, current
The pitch that scraper plate scrapes is gone out from nozzle 5;With the rotation of drive disk 9, the second drive block 13 drives the second block 11 gradually
Turn to lower quadrant point from upper quadrant point counterclockwise, in the process the second drive block 13 compared with the second block 11 gradually to circle
It is moved at the heart, 13 outside of the second drive block is just mutually neat with 13 inside of the second drive block when turning to lower quadrant point, i.e., the two is de-
It opens, the second drive block 13, which is rotated further, will no longer drive the second block 11 to rotate;In above process, the spool 8 at rear is inverse
When hour hands rotate take-up, steel wire rope 14 pulls the spool 8 in front to rotate clockwise unwrapping wire, due to two 8 diameter phases of spool
Together, so two 8 angular speed of spool are identical, the first block 10 rotates clockwise and the second block 11 with the spool 8 in front
Lower quadrant point is reached simultaneously, with upper quadrant point on the contrary, at lower quadrant point, the second drive block 13 and the second block 11 disengage, the
One drive block 12 and the first block 10 are bonded, and drive disk 9 is rotated further, and the first drive block 12 drives front by the first block 10
Spool 8 rotate counterclockwise beginning take-up, steel wire rope 14 pulls the spool 8 at rear to rotate clockwise unwrapping wire, steel wire rope 14
For head end take-up tail end unwrapping wire so as to pull steel wire rope 14, steel wire rope 14 drives multiple first scraper plates 6 thereon to left movement, multiple
Second scraper plate 7 moves right, and the first scraper plate 6 and the second scraper plate 7 respectively carry out the first spreading tube 1 and 2 inner wall of the second spreading tube
It scrapes clearly, while the first drive block 12 and the first block 10 rotate counterclockwise to upper quadrant point, the second block 11 turns clockwise
It moves at upper quadrant point, the first drive block 12 and the first block 10 disengage, and the second drive block 13 and the second block 11 are bonded, one
Cycling is terminated;Drive disk 9, which is rotated further, drives the spool 8 at rear to rotate counterclockwise, and the spool 8 in front is drawn by steel wire rope 14
Dynamic reversion clockwise, i.e., next Xun Huan start;By the fitting and disengagement of two drive blocks and two blocks, in a Xun Huan
Interior, the spool 8 of 9 driven front and back of drive disk respectively rotates 180 degree, realizes that the once reciprocal of steel wire rope 14 pulls;
Drive disk 9 persistently rotates, and spread inside pipe wall is scraped clearly so as to which multiple scraper plates be driven repeatedly to move back and forth.
After cycling several times, remaining pitch is cleaned in spreading tube, at this time closing drive device, drive disk 9 and volume
Spool 8 stops operating, then bitumenpump is shut down, closes each switch valve, finally tighten spreading tube by multiple scraper plate stop motions
The end cap 15 at both ends, for end cap 15 when inwardly tightening, conical seal ring 17 is flared 18 crimps by the taper of spreading tube nozzle,
So that the second cord hole 19, which is shunk, compresses steel wire rope 14, sealing is realized;So far whole work process terminates, to treat next use.
The present invention has the advantages that following notable:
1st, asphalt distribution is uniform;The present invention devises two spreading tubes being arranged side by side, and makes two spreading tube any positions
Asphalt distribution pressure is complementary, so that it is identical along the asphalt distribution amount of pipe range direction any position, completely solve traditional asphalt
Spreading tube to make the non-uniform problem of asphalt distribution along pipe range there are pressure drop, and without installing any pressure stabilizing device or pressure compensation additional
Equipment is not required in addition set control mechanism, does not increase cost and operation difficulty, be skillfully constructed, use is simple and effective.
2nd, pitch can be more effectively in injection rubble gap;The present invention is devising two spreading tubes being arranged side by side
Meanwhile adjustment is had also been made to 5 direction of nozzle on each spreading tube, the nozzle 5 on two spreading tubes is made to spray direction on the contrary, making
Pitch can be from the rubble gap of the different trends of the more effectively direct injection of both direction, and ensureing can injection in rubble gap
Enough pitch avoids penetrating into each gap due to being unable to effective flowing before cooling after pitch ejection during traditional unidirectional sprinkling
In and form weak spot, make road surface since weak spot burst it is bad.
3rd, the present invention is more thoroughly effective to the cleaning of spreading tube;Traditional asphalt distribution equipment is mostly simple by the molten of diesel oil
Remaining pitch in solution and flushing action cleaning spreading tube, the method cleaning slowly get to clean, it is necessary to rinse for a long time
It is required that and cleaning be not thorough, and waste massive diesel-fuel, the present invention multiple scraper plates are devised in spreading tube, further through two
The mutual cooperation of drive block and two blocks realizes that drive disk rotates alternating in one week and two spools is driven respectively to rotate half cycle,
And then the reciprocating motion of scraper plate is realized by the take-up unwrapping wire of steel wire rope, so that pitch be struck off from spread inside pipe wall, then use
Water washes away, and thoroughly can rapidly strike off very much the residual asphalt of spread inside pipe wall adherency using scraper plate, and no longer need
Diesel oil dissolves, and need to only be gone out with water, and cleaning is quick thorough, and effect is good efficient, and avoids waste diesel oil.
To sum up, asphalt distribution of the present invention is uniform, in energy more effectively injection gap, is cleaned using rear asphalt distribution pipe thorough
Quickly, pitch felt jam in spreading tube is avoided;Present inventive concept is novel, and clever structure, significant effect is easy to use, real
It is strong with property.
