Description

Technical Field

This invention is low-cost, simple in structure, easy to manufacture, and simple to operate, adaptable to various road surfaces. The paving machine replaces the traditional bending / squatting paving method with upright walking paving, greatly liberating labor, improving paving efficiency, and saving significant manpower and resources.

[0004] However, in actual use, it lacks an integrated structure for pouring and paving blocks. During the pouring and paving process, it is difficult to adapt and adjust the width of the sidewalk, resulting in low construction efficiency, insufficient adaptability, and inconvenient adjustment. Furthermore, during the pouring process, due to the large difference in the ratio of cement and medium sand, the resulting concrete slurry has low fluidity, making it difficult for traditional discharge devices to achieve sufficient pouring.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: The present invention provides a one-time forming paving device for sidewalks and its method of use, achieving the following beneficial effects:

[0018] (1) In order to solve the problem that the concrete slurry formed by the large difference in the proportion of cement and medium sand has low fluidity and traditional discharge devices are difficult to achieve full pouring, the present invention proposes a pressurized uniform pouring mechanism. By setting up an air pump, piston and spring, pressurized discharge is achieved, which is suitable for concrete slurry with low fluidity.

[0019] (2) By utilizing the combination of the discharge tank and the discharge pipe, the number of discharge ports for pouring is increased without adding a connecting valve, thus achieving uniform pouring and filling.

[0020] (3) By using the brick position self-correcting brick laying mechanism, in conjunction with the horizontally installed conveyor belt and clamping plate, the purpose of calibrating the brick discharge position is achieved, which greatly reduces the requirements for the conveyor belt transmission position accuracy.

[0021] (4) The integrated structure of casting and block laying proposed in this invention has the problem that it is difficult to adapt and adjust the width of the sidewalk during the laying and casting process, resulting in low construction efficiency and insufficient adaptability. It also solves the problem that traditional material discharge devices cannot achieve full casting.

[0022] (5) By setting a chamfer, when the push plate is pushed laterally, due to the position error, the brick is pressed laterally against the side wall of the chamfer, causing the clamping plate to shift laterally. With the push and lateral squeezing, the position of the brick is corrected, so that the brick is facing the brick outlet.

[0023] (6) The conveyor belt is used to support multiple sets of bricks and avoid placing the bricks directly on the transmission chain frame. The second spring and the first guide rod work together to achieve the purpose of elastic installation. When the bricks are pushed to the rotating plate, the bricks can be adjusted laterally due to the pressure of the position offset.

[0024] (7) The setting of the elastic telescopic component allows the rotating plate to be reset under the elastic action of the elastic telescopic component. Attached Figure Description

[0045] In practical use, first start motor 20. The rotation of motor 20 drives the stirring rod 19 to rotate, stirring the slurry in the mixing tank 18. Open the connecting valve 21 to put the slurry into the feed tank 8. Start the air pump 22 and open the connecting valve 30. The piston 24 is driven to descend by pressurization, and the first spring 25 is compressed, increasing the pressure inside the feed tank 8. Through the cooperation of the discharge pipe 27 and the discharge tank 29, pressurized discharge is achieved. The discharge pipe 27 can introduce slurry into the discharge tank 29 through the inclined connecting pipe 28. By setting the cooperation of the discharge pipe 27 and the discharge tank 29, without increasing the connection... With valve 30 in place, the number of pouring outlets has increased, achieving uniform pouring and filling. The output end of motor 39 rotates, driving gear 40 to rotate. Gear 40 rotates, driving chain 41 to rotate. Chain 41 rotates, driving first guide rod 44 to rotate. First guide rod 44 rotates, driving conveyor belt 38 to rotate.

Push plate 48 moves, driving top ball 49 to move, pushing the bricks onto rotating plate 51. The lifting rod 52's output end moves, driving the pressure plate 53 to move. The pressure plate 53's movement pushes the bricks downwards, causing the rotating plate 51 to rotate. When the rotating plate 51 rotates 90 degrees, the lower end of the brick is directly opposite the brick outlet 35, achieving the purpose of laying the bricks. After the bricks are laid, the rotating plate 51 returns to its original position under the elastic action of the elastic telescopic member 59. By setting a pair of symmetrical clamping plates 56, multiple sets of bricks are laterally squeezed and clamped. Then, under the vertical pressure of the pressure plate 53, the bricks are kept elastically pressed and move downwards. By setting a chamfer, when the push plate 48 is pushed laterally, the bricks are further compressed and pressed downwards. Due to positional errors, the bricks are pressed laterally against the chamfered sidewalls, causing the clamping plate 56 to shift laterally. With advancement and lateral compression, the position of the bricks is corrected, ensuring that the bricks are aligned with the brick outlet 35. The conveyor belt 38 is used to support multiple sets of bricks, preventing them from being placed directly on the transmission chain frame 37. The second spring 43 and the first guide rod 44 work together to achieve elastic installation. When the bricks are advanced to the rotating plate 51, the pressure caused by the positional shift allows the bricks to be adjusted laterally. This is the overall workflow of the invention. This step can be repeated for the next use.
