When the placing bracket 431-5 is pulled out after placing the road floor tile, the mechanical arm supporting leg can prop against the laid brick body, so that the brick body with good exterior is prevented from moving. The rear slide rail supporting plate 401 is fixedly connected with the front slide rail supporting plate 402 through a quick-release connecting plate 403, and the pavement brick laying mechanism 400 is detachably arranged between quick-release mounting brackets 531 on two sides through the quick-release connecting plate 403.

Wherein, the colors of the first positioning laser 421-1 and the second positioning laser 422-1 are different, so that we can conveniently judge whether the first positioning laser 421-1 and the second positioning laser 422-1 on the same side of the ground are overlapped.

The working process of the pavement brick is described in detail as follows:

firstly, bricks (pavement bricks or curbs) are stacked on a fork of a forklift, and the front side and the back side of the stacked bricks are contacted. Then we put down the warehouse rack 130 to be in a horizontal state and drive the forklift to transfer the stacked floor tiles onto the warehouse rack 130, since the warehouse rack 130 is rotatably connected to the bottom center of the longitudinal lifting rack 102, a space for the fork to travel is formed at both sides of the warehouse rack 130, and the forklift can extend into the center of the opening of the fork when running near the flat brick laying device 10. And the floor tile is removed and separated after the forklift is driven into place.

A second conveyor 132 of rollers or belts is provided on the warehouse rack 130, and stacked bricks are conveyed forward by the second conveyor 132 onto the lift plate 103. The ejector pins of the lifting devices 120 on both sides of the lifting plate 103 slide upwards, and the ejector pins drive the lifting webs 106 on both sides to move upwards steadily by moving upwards through the lifting chains 122, so that the height of the lifting plate 103 is lifted as shown in fig. 3 b.

The clamping device 220 of the clamping and pushing mechanism 200 slides backwards to the tail direction, the clamping plate 225 clamps and fixes the left end and the right end of the uppermost brick, and then the clamping device 220 moves towards the head direction. The clamping device 220 slides forward in the process that the second roller 221 slides into the lower lifting rail 213 to lift the self height, so that the clamping device 220 slightly lifts the height of the brick while driving the brick to move forward, and the clamped brick is prevented from being scraped with the brick on the lifting plate 103, so that the attractiveness of the brick is affected.

When the gripping device 220 slides on the advancing rail 210 over the conveyor 300, the two jaws 225 are released, the brick falls onto the conveyor 300 and the lying brick continues to be conveyed forward by the conveyor 300.

The above steps are general steps of the paving brick laying mechanism 400 and the kerb laying mechanism 600, and when paving a paving brick, the paving brick laying mechanism 400 is mounted on the mechanical arm 500, and the paving process of the paving brick laying mechanism 400 is as follows:

after the carriage moves to the designated position of the paving area, the position of the paving brick paving mechanism 400 is positioned by the positioning mechanism 320, the turning cylinder 434 drives the turning mechanism 430 to integrally turn over, so that the saw-tooth scraping plate of the scraping mechanism 432 is in inclined contact with the ground, and then the horizontal telescopic cylinder 406 drives the turning mechanism 430 to integrally move back and forth on the setting frame to scrape the ground, as shown in fig. 6 g.

After the ground is scraped, the tile transferred by the transfer mechanism 300 is transferred between the pallet 431-4 and the bracket 431-5 through the support plate 407 so that the tile is held by the placement mechanism 431. Then the turnover cylinder 434 drives the turnover mechanism 430 to integrally turn over, so that the placement mechanism 431 with bricks clamped at the rear side is turned over to the front side and is in a horizontal state, as shown in fig. 6h-6i, and then the horizontal telescopic cylinder 406 drives the turnover mechanism 430 to retract, so that the bracket 431-5 is pulled out from the gap between the pavement brick 01 and the ground, and the pavement brick 01 is paved on the ground.

Then, the turning cylinder 434 drives the turning mechanism 430 to integrally turn over, so that the rolling mechanism 433 turns over to make the first rolling wheel contact with the upper surface of the laid tile, and then the horizontal telescopic cylinder 406 drives the turning mechanism 430 to move back and forth, and the first rolling wheel rolls back and forth the upper surface of the laid tile, as shown in fig. 6 j.

After the rolling is completed, the horizontal telescopic cylinder 406 drives the tilting mechanism 430 to retract to the initial position, and the tilting mechanism 430 is driven by the tilting cylinder 434 to tilt to a state in which the placing mechanism 431 is connected with the conveying mechanism 300 (i.e., to return to the state of fig. 6 e). The body is then moved to the next brick laying position, with the positioning provided by two sets of positioning mechanisms to ensure that the laid bricks fall into the designated positions.

When paving a curb, the curb paving mechanism 600 is mounted to the mechanical arm 500, and the paving process of the curb paving mechanism 600 is as follows:

when the conveyor 300 moves to the forefront, the curb 02 is firstly blocked by the buffer plate 620, the underside of the curb 02 (i.e. the bottom edge for contacting the ground) is contacted with the buffer plate 620, then the buffer plate 620 is turned down, the curb 02 loses the blocking of the buffer plate 620 and slides onto the guide slope plate 613, the curb 02 slides forward on the guide slope plate 613 under the action of gravity, and the curb 02 is blocked by the positioning guard plate 616 to stand in the curb paving groove in the Y direction when falling from the guide slope plate 613, and at this time, the paving operation of one curb 02 is completed, so that the curb 02 stands in the curb paving groove on the ground.

Subsequently, the traveling device 12 drives the brick paving machine 10 to transversely move in the Y direction, and the crushed soil cleaning plate 640 located at the front side of the paving direction is in a sagging state, so that the crushed soil in the curb paving groove can be cleaned out by the crushed soil cleaning plate 640 in the advancing process of the curb paving equipment, so that the curb paving groove is smoother, and the follow-up curb falls into the paving groove to be wholly tidier. The crushed soil cleaning plate 640 positioned at the rear side of the paving direction rotates to a horizontal state, the second roller 641 of the crushed soil cleaning plate 640 is rolled on the upper surface of the curb 02 at the rear side of the curb paving frame 610 in the paving direction, and downward rolling operation is carried out on the curb paved at the rear side in the traversing process of the brick paving machine 10; the thickness positioning wheel 630 positioned at the rear side of the paving direction is abutted against the back surface of the curb paved at the rear side, and the thickness positioning wheel 630 provides forward rolling operation for the curb in the process of traversing; by rolling down and forward the curb paved in the rear, the paved curb can be tidier.
