The process of laying the pavement tiles is described in detail below with reference to fig. 1-11, and fig. 12 and 13:

starting belt conveyor 16, artifical placing the unordered brick of standard size to belt conveyor 16's upper surface, the direction of placing roughly makes brick length border fore-and-aft direction, roughly is perpendicular with preceding baffle 15 and backplate 17 on belt conveyor 16, because artifical placing, the brick can produce the skew, consequently can not be completely perpendicular. When the belt type conveyor belt 16 rotates, the first motor 9 starts to work to drive the crank 10 to rotate, the crank connecting rod 12 hinged with the crank connecting rod starts to rotate back and forth relatively, so that the hinged crank push rod 13 is driven to do back and forth reciprocating brick pushing motion in the horizontal direction in the sliding rail of the front baffle 15, the distance between the front brick pushing and the rear brick pushing is 60 mm, the front baffle 15 contacts bricks under the repeated pushing of the crank push rod 13 to arrange the bricks, the long edges of the bricks are further perpendicular to the front baffle 15 or the rear baffle 17, and the bricks can still incline and are not completely perpendicular. Then, under the movement of the belt conveyor 16, bricks move to the left and firstly come to the position right below the support 19, because the distance between the bottom of the roller 21 and the belt conveyor 16 is slightly smaller than the thickness of a standard brick, the brick cannot immediately pass through the support 19 and can be blocked in front of the support 19, but under the continuous driving of the belt conveyor 16, the inclined bricks sequentially contact the circular ring-shaped rollers 21, when both circular ring-shaped rollers 21 receive an upward component force brought by the brick, the component force is transmitted to the cross rod 23 in a connection relationship and becomes an upward thrust force, then the cross rod 23 moves upwards along the cylindrical track 30, then the two connecting rods 26 hinged with the circular ring-shaped rollers expand outwards to push the two shells 28 to move away, the springs 25 connected with the shells are stretched, and then the two grabbing hooks 29 fixed on the shells 28 clamp inwards and slide to the bottom ends of the grooves on the ejector rods 22, the lifting rod 22 is driven to move upwards by the gripping hook 29, so that the two circular ring-shaped rollers 21 blocking the bricks are lifted simultaneously. Due to the resistance effect of the circular ring-shaped roller 21 on the left side edge of the brick, the brick is enabled to be placed in the front and back positions, the long edge of the brick is completely vertical to the front baffle 15 and the back baffle 17, and the brick is driven by the belt type conveyor belt 16 to move leftwards continuously according to the adjusted direction. When the bricks completely pass through the bracket 19, the circular roller 21 loses the supporting force of the bricks and moves downwards to reset, the ejector rod 22 and the cross rod 23 are driven to move downwards, the connecting rod 26 contracts inwards, the spring 25 contracts at the moment, the two shells 28 move towards each other under the elastic force generated in the retraction process of the spring 25, the grapple 29 is loosened outwards, and moves upwards along the groove of the ejector rod 22 to return to the initial state.

Then, the bricks move to the lower part of the soft rubber roller 33, the second motor 34 works to drive the soft rubber roller 33 to rotate, and the bricks can still pass through the brick inlet according to the previous position and stably enter the roller type conveyor belt 42 through the slide rail 32 under the action of extrusion and friction force when passing through the soft rubber roller 3. Under the drive of the drum-type conveyor belt 42, the bricks continue to move leftwards until the bricks touch the left side fence 43 or the bricks arranged in front of the left side fence stop moving. When bricks on the drum-type conveyor belt 42 reach the designated mass and a pressure sensor below the drum-type conveyor belt 42 detects a mass signal, the air cylinder 41 works to push the concave-convex push rod 40 to move forwards, so that bricks originally arranged orderly are also arranged in a concave-convex shape.

When the concave-convex push rod 40 is pushed forwards, the triangular support plate 38 fixedly connected with the concave-convex push rod moves forwards, the baffle roller 36 contacted with the triangular support plate 38 moves downwards along the inclined edge of the triangular support plate 38, the brick inlet baffle 37 also performs slow descending motion, and when the roller 36 stops moving, the brick inlet baffle 37 stops descending and is blocked at the brick inlet of the roller type conveyor belt 42, so that the brick pushing process and the brick feeding process are not interfered with each other. If a brick is just in the brick inlet in the brick pushing movement, the brick inlet baffle 37 can press the brick by the self gravity to complete the blocking function. When the concave-convex push rod 40 moves backwards under the action of the air cylinder 41, the triangular support plate 38 moves upwards, the roller 36 contacted with the triangular support plate also moves upwards, the brick inlet baffle plate 37 connected with the triangular support plate moves upwards to lose the blocking effect, and the blocked bricks continue to move forwards.

Under the continuous propulsion of the concave-convex push rod 40, the whole row of bricks are pushed away from the drum-type conveyor belt 42, finally, the bricks arranged in the concave-convex latch mode reach the arc transition plate 4, and due to certain friction between the bricks, the bricks cannot damage the previously arranged array shapes due to the height difference when passing through the arc transition plate 4. The bricks reach the brick laying track 2 through the arc transition plate 4, after the bricks enter the brick laying track 2, because the friction force on the brick laying track 2 is greater than the discrete gravity of the bricks, the arranged bricks can stay on the brick laying track 2 under the condition of no external force until the concave-convex push rod 40 pushes the next row of bricks, the bricks in the next row and the bricks in the previous row are clamped with each other in a concave-convex mode, the bricks in the next row are pushed by the air cylinder 41 to prop against the bricks in the previous row, and the bricks in the previous row are pushed forwards at the same time. When a brick touches the pressure sensors at the breast boards at two sides of the brick paving track 2, the driving wheel 31 driving device starts to slowly walk backwards, and the walking speed is slightly less than the moving speed of the whole row of bricks.

When the lowermost brick row is pushed to the cement ground, the cylindrical roller 1 compacts the laid bricks by means of the gravity of the cylindrical roller, and thus, one-time brick laying is completed. The device has the maximum left and right paving width of 3 m, and roads with different widths can be paved by moving the right breast board 3 hinged on the screw rod 5 and simultaneously changing the parameter setting of the pressure sensor arranged below the drum-type conveyor belt 42.
