Description

Technical Field

[0001] This invention relates to the field of bricklaying machinery and equipment, specifically to a bricklaying machine for construction sites. Background Technology

[0002] Bricklaying refers to the process by which construction workers stack bricks with concrete to form a wall. Currently, bricklaying is still done manually, requiring multiple workers to work on the same wall simultaneously. This increases labor costs, and scaffolding is needed to assist in stacking bricks to a certain height, resulting in consistently low efficiency.

[0003] The reference publication number is "CN114352044A" entitled "An Auxiliary Bricklaying Device for Construction Sites". It states that "existing auxiliary bricklaying devices do not have a flow guiding device, which results in slow flow of concrete due to its high viscosity, thus slowing down the workers' work efficiency. Furthermore, existing auxiliary bricklaying devices cannot adjust the width of the concrete applied to the device according to the different types of bricks."

[0004] The technical solution to the above problem is as follows: by setting up a storage box, a motor, a rotating shaft, a threaded column, and a push plate, the motor drives the rotating shaft to rotate, the rotating shaft drives the threaded column to rotate, the threaded column drives the nut to move horizontally, the nut drives the push plate to move horizontally, and the push plate pushes the concrete in the storage box towards the discharge port, thereby accelerating the flow of viscous concrete towards the discharge port and improving the work efficiency of workers; by setting up a discharge port, a threaded groove, a baffle, and screws, the baffle can be slid according to the size of the brick, so that the baffle blocks the discharge port that is larger than the width of the brick, so that when the concrete flows out of the discharge port, it just lands on the upper surface of the brick, thereby realizing the ability to change the size of the opening according to the size of the brick.

[0005] Current bricklaying machines have certain limitations in terms of bricklaying height. As the height of the wall increases, the height of the bricklaying machine must also be increased. To ensure the stability of the stacking, a mechanical arm is needed to adhere concrete to both sides of the bricks before stacking them on the wall. This method increases the time spent adhering concrete to the bricks, thus delaying the stacking progress. Therefore, a bricklaying machine was developed. Summary of the Invention

[0022] Example 1

[0023] Please refer to the following: Figure 1-6 This invention discloses a bricklaying machine for construction sites, comprising a base 1, a pusher box 3 fixedly connected to the top of the base 1 near one edge, a conveyor belt 2 provided on one side of the pusher box 3, a lifting rod 5 embedded in the top of the base 1 and on one side wall of the pusher box 3, a collection box 6 detachably connected to the output end of the lifting rod 5 by screws, an extension plate 13 fixedly connected to the bottom edge of one end of the base 1, a concrete storage box 14 fixedly connected to the top of the extension plate 13 away from the base 1, a discharge port 4 fixedly connected to the side wall of the pusher box 3 opposite to the conveyor belt 2, the pusher box 3 having a conical structure, a feeding pipe 17 fixedly connected to the side wall of the base 1 opposite to the concrete storage box 14, a branch pipe 18 fixedly connected to one side wall of the feeding pipe 17, the branch pipe 18 having a telescopic structure, the outlets of the feeding pipe 17 and the branch pipe 18 extending into the pusher box 3 and the collection box 6 respectively, and one end of the branch pipe 18 fixedly connected to one side wall of the collection box 6;

[0024] The top of the base 1 is connected to the mounting base plate 11 by screws on the side edge of the lifting rod 5. The top of the mounting base plate 11 is rotatably connected to the robotic arm 12, which is a four-axis linkage structure. One end of the robotic arm 12 is fixedly connected to the gripper cylinder. The side edge of the extension plate 13 is fixedly connected to the column 15. The top of the column 15 is embedded with the positioning camera 16. Bricks are evenly placed on the conveyor belt 2, which is a step feeding structure.

[0025] The pusher box 3 is detachably inlaid with a telescopic column 20 on the side wall opposite to the feeding pipe 17 and near the bottom edge. The output end of the telescopic column 20 extends into the pusher box 3. A push plate 25 is provided inside the pusher box 3. The push plate 25 is detachably connected to the output end of the telescopic column 20 through a docking column in the middle of its side wall. The isolation plate 24 has an L-shaped structure. A receiving plate 32 is fixedly connected to the bottom side wall of the pusher box 3 at the discharge port 4. The bottom of the receiving plate 32 is set with an inclined structure.

[0026] A material collection box 6 is fixedly connected to one side wall. A screw rod 26 is rotatably connected inside the material collection box 6. A driver 27 is embedded in the bottom side wall of the material collection box 6. The output end of the driver 27 extends into the lifting pipe 7 and is detachably connected to one end of the screw rod 26 by screws. A discharge box 8 is fixedly connected to the end of the lifting pipe 7 away from the material collection box 6. The bottom side wall of the material collection box 6 has an inclined structure. An outlet is opened through one side of the discharge box 8 near the edge. A guide plate 9 is fixedly connected to the bottom edge of the outlet. An anti-overflow plate 10 is fixedly connected to the top edges of both sides of the guide plate 9. A fixing block 28 is fixedly connected to the top side wall of the discharge box 8 above the outlet. A threaded post 29 is threadedly connected through the middle of the fixing block 28. A baffle 30 is rotatably connected to the bottom end of the threaded post 29 of the fixing block 28. The baffle 30 fits against one side of the outlet.

[0027] The bricks are placed on the conveyor belt 2 and transported towards the push box 3. Then, the robotic arm 12 is started to control the movement and adjustment of the gripper cylinder. The gripper cylinder then clamps and transports the bricks. After the bricks are picked up, they are controlled by the mounting base plate 11 and the robotic arm 12 to fit into the opening of the discharge port 4. The gripper cylinder then moves the bricks to make the concrete adhere to one end of the bricks. Finally, the mounting base plate 11 drives the robotic arm 12 to rotate and stack the bricks on the wall.

[0028] To improve stacking efficiency, concrete is fed into the machine's aggregate box 6 through the branch pipe 18. Then, the driver 27 is started, which drives the screw rod 26 to rotate. As the screw rod 26 rotates, the concrete injected into the aggregate box 6 is sent into the lifting pipe 7 through the screw conveyor structure. The concrete is then conveyed outward along the lifting pipe 7 and sent into the discharge box 8. After entering the discharge box 8, the concrete will be discharged from the outlet under the influence of gravity. The concrete is then laid on the wall by the movement of the base 1. Because the bottom concrete is laid on the wall in advance, it is only necessary to apply concrete to one end of the rotating block to lay the concrete on the wall.

[0029] The drive 27 is turned on and off at regular intervals to prevent concrete from accumulating on the wall due to the continuous movement of the screw rod 26, thus avoiding concrete waste. The installed guide plate 9 and anti-overflow plate 10 ensure that the concrete is accurately laid on the wall and prevent concrete from overflowing from both sides of the guide plate 9, thus avoiding resource waste. The installed lifting rod 5 can raise the aggregate box 6 as the height of the wall increases, ensuring the smooth progress of the wall construction.

[0030] Concrete is fed into the pusher box 3 through the feeding pipe 17. The telescopic column 20 is activated to drive the pusher plate 25 to move. As one end of the pusher plate 25 pushes the concrete to continue moving, the concrete is squeezed out from the discharge port 4, making it easier for the concrete to adhere to the bricks. Because the pusher plate 25 has an L-shaped structure, when the telescopic column 20 moves backward, it will squeeze the concrete located behind the pusher plate 25 to the front of the pusher plate 25, thereby achieving a continuous and stable push of the concrete outward and avoiding the accumulation of concrete in the pusher box 3, which would cause waste. For this reason, the pusher box 3 is equipped with a conical structure to ensure that the concrete is accurately pushed out from the discharge port 4. In order to avoid waste, a receiving plate 32 is set to receive and store the fallen concrete for later reuse.

[0031] The above method can accurately save a stacking step, thereby improving stacking efficiency. By pre-laying concrete on the wall, it is easier to lay bricks later. Through the cooperation of the robotic arm 12 and the lifting pipe 7, the concrete laying and brick stacking can be effectively ensured.

[0032] Example 2

[0033] Please see the appendix Figure 2-3 A mixing column 22 is rotatably connected to the inner side wall of the concrete storage tank 14. Support columns are evenly fixedly connected to the mixing column 22. A motor 21 is detachably connected to the outer wall of one end of the concrete storage tank 14 by screws. The output end of the motor 21 extends into the concrete storage tank 14 and is fixedly connected to one end of the mixing column 22. A conveying pump 19 is detachably connected to the middle of the side wall of the concrete storage tank 14 opposite to the base 1 by a flange. The conveying pump 19 is detachably connected to one end of the feeding pipe 17 through one end away from the concrete storage tank 14.

[0034] The feeding pipe 17 has a Z-shaped structure. Inside the feeding pipe 17 and at the connection with the branch pipe 18, a rotating column 23 is rotatably connected by a torsion spring. A partition plate 24 is fixedly connected to one side wall of the rotating column 23. The partition plate 24 is normally vertical and fits against the connection between the branch pipe 18 and the feeding pipe 17. A conical stop is fixedly connected to the inner wall of the feeding pipe 17. A knob 31 is rotatably connected to the outer wall at the connection between the feeding pipe 17 and the branch pipe 18. The knob 31 extends into the feeding pipe 17 and is fixedly connected to one end of the rotating column 23.

[0035] Rollers are fixedly connected to the four corners of the bottom of the base 1. The base 1 is rotatably connected to the side wall of the mounting base plate 11, and the rollers are in contact with the wall. The rollers ensure that the base 1 can move smoothly. In order to reduce the friction between the base 1 and the wall, the corresponding rollers are set. When the base 1 moves, the rollers will also rotate synchronously, thereby avoiding wear on the wall due to friction.

[0036] To increase the flexibility of the application, rotating the threaded column 29 pushes the baffle 30 downward through the threaded connection, thereby adjusting the outlet size and the concrete discharge volume, and making flexible adjustments according to the actual situation.

[0037] Starting the delivery pump 19 can send the concrete stored in the concrete storage tank 14 into the delivery pipe 17, and then the concrete is injected into the pusher box 3 along the delivery pipe 17 to wait for it to be spread on one side wall of the brick. The branch pipe 18 is connected to the delivery pipe 17 and the concrete is sent into the collection box 6 along the branch pipe 18. In order to cooperate with the lifting of the collection box 6, the branch pipe 18 is set as a telescopic structure. In order to prevent the concrete from solidifying in the concrete storage tank 14, the mixing column 22 driven by the motor 21 can be rotated to prevent the concrete from solidifying.

[0038] To ensure the accuracy of brick placement during stacking, corresponding pillars 15 and positioning cameras 16 are set up. The positioning cameras 16 are used to locate the stacked bricks, and then the base 1 is moved to the designated position by rollers to place new bricks, so as to avoid the stacked wall being crooked and unstable.

[0039] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
