Column 85 is provided with the stripper plate 86 matched with the squeezing tank 81 on the hydraulic column 85.It is set in the squeezing tank 81
Several squeezing passages 82 are equipped with, the squeezing passage 82 is arranged in a straight line and interval is uniform, 81 bottom angled of squeezing tank
Setting, squeezing passage 82 are located at 81 bottom lowermost end of squeezing tank.
The molding laying device 7 includes molding machine 9 and laying device 4, and the laying device 4 includes paving slab
41.The molding machine 9 includes mold 91 and pressing mechanism, is provided with and 82 phase of squeezing passage on the mold 91
The feeding inlet 911 and discharge port 912 of cooperation are provided with several type chambers, the feeding inlet 911 and institute in the mold 91
The discharge port 912 stated is separately positioned on type chamber both ends.It is additionally provided with baffle mechanism and pressing mechanism on the mold 91,
The baffle mechanism includes baffle motor 94, inlet baffle 92 and outlet damper 93, the inlet baffle 92 and described
It is provided with damper rod 96 between outlet damper 93, the rotation with the damper rod 96 cooperation is provided on the baffle motor 94
Sliding block 95.The limited block 42 matched with the outlet damper 93, the baffle machine are provided on the laying device 4
Structure controls the opening and closing of the feeding inlet 911 and the discharge port 912.The pressing mechanism includes that adding on car body 1 is arranged in
Depressor 71, the pressurizer 71 include several pressure rods 72 corresponding with the feeding inlet 911, and the pressure rod 72 is right
91 inner mold chamber of mold applies pressure.91 bottom of mold is additionally provided with several air holes.
The raw material for making brick are put into agitator tank 21, stirring wheel 22 by stirring motor 11 drive to raw material into
Row stirring, raw material are evenly stirred until when reaching requirement, adjust motor 24 and movable plate 26 is driven to rotate, in rotation process
In, rubber membrane 27 can prevent the raw material being stirred from revealing as movable plate 26 is by drawing exhibition.Movable plate 26 reaches predetermined position
Afterwards, sand material can be entered in squeezing tank 81 by movable plate 26, and after whole raw material enter, movable plate 26 turns round again, carries out down
Primary raw material stirring.After sand material enters squeezing tank 81, the stripper plate 86 on top is compressed by hydraulic column 85, stripper plate
86 following table area is identical as the sectional area of box body 81 is squeezed, and the height that stripper plate 86 declines every time is identical, the height of decline
It is the volume in all 91 type chambers of mold full of raw material divided by the sectional area of squeezing tank 81, sand material is under the pressure of stripper plate 86
Enter that 91 type of mold is intracavitary, and after sand material has all been squeezed in squeezing tank 81, hydraulic column 85 is by stripper plate by feeding inlet 911
86 retract top, to prevent stripper plate 86 from hindering the rotation of movable plate 26.
The feeding inlet 911 of mold 91 is connect with the squeezing passage 82 in squeezing tank 81, and sand material enters mould by feeding inlet 911
After tool 91, baffle motor 94 drives outlet damper 93 to seal material mouth 912, while outlet damper 93 is limited the card master of block 42.
Inlet baffle 92 is in folding condition under the action of damper rod 96 and turning block 95 at this time, then passes through control pressurizer
71, allowing the pressure rod 72 on pressurizer 71 to extend into from feeding inlet 911,91 type of mold is intracavitary to pressurize to sand material, even if pressurization
Great efforts, outlet damper 93 remains to fitting discharge port 912 inflexibly under the action of limited block 42, prevents sand material from overflowing, together
When in 91 bottom of mold be additionally provided with several air holes, the air for being discharged in pressure process in sand material, even if part
Sand material is overflowed from air hole, nor affects on entire pressurisation effect.Brick forms in mold 91 after pressurization, releases add at this time
Compression bar 72, then 94 opposite direction of baffle motor rotates, and allows outlet damper 93 to rise and opens discharge port 912, while allowing inlet baffle
92 lower into feeding inlet 911, due to being provided with interval trough on inlet baffle 92, inlet baffle 92 are allowed to be deep into mould
Have that 91 types are intracavitary to eject brick.Then brick enters tile work plate 41, and there are low-angle inclined-plane in 41 two sides of tile work plate, can be by each mold
The brick produced in type 91 is gathered together, the spacing between reducing, as brick constantly is produced out, finally
Brick can be extruded into road surface, finally be tiled onto ground.Paving slab 41 generally tilts installation, and setting angle is arrived at 30 °
Between 45 °.Agitating device 2, pressurizing unit 8, molding laying device link always in the whole process, continual to carry out entirely
Work.
The flattening mechanism 5 includes screed 51, is uniformly intensively provided with several on the screed 51 and loosens the soil
Pawl 52.After equipment is started, paving machine is advanced forward by wheel 3, and in order to make the brick of laying neatly steady, loosening the soil pawl 52 will i.e.
The wheel print that the large clod for needing the road surface being laid with and wheel rolled is loosened the soil, the soil for crossing pine using screed 51
Carry out it is smooth, to facilitate the laying of brick on tile work plate.It further include rolling body 6, the rolling body 6 includes connecting rod 61,
Described 61 one end of connecting rod is hinged by hinge 62 and car body 1, and 61 other end of connecting rod is connected with connection frame 63, institute
It states connection frame 63 and is rotatably connected to milling roller 64.Brick in tile work plate 41 is laid on ground under extruding force and gravity
On, although there is the leveling of flattening mechanism 5, still exists and be laid with jiggly problem, by milling roller 64, by what is laid
Brick is rolled, allow laying transform it is steady neat.The size and weight of milling roller 64 can change, to be suitble to difference
Laying demand.Uniform circular is provided with anti-skid bulge 31 on the tire 3.Since the travel speed of whole device is slower,
Anti-pulley form can be used in tire 3, and the road surface that wheel can be made to roll in this way is not in the impression of large area, facilitates smooth
Mechanism work.
