Description

Technical Field

[0001] This invention relates to the field of construction machinery technology, specifically to an automatic brick plastering machine and its plastering method. Background Technology

[0002] Bricklaying is a common construction method in modern architecture. With the increasing automation of construction, manual bricklaying will gradually be replaced by machines. Applying mortar to the surface of the bricks is a crucial step in the bricklaying process. A mortar applicator is a device that automatically applies mortar to the laid bricks during the bricklaying process. To improve mortar application efficiency, mortar applicators are typically used.

[0003] However, during the bricklaying process, the sides of two bricks need to be connected with mortar. Therefore, it is necessary to apply mortar to the sides of the bricks. Existing mortar application machines can only apply mortar to the top surface of the bricks, and manual application of mortar to the sides of the bricks is still required. The degree of automation is not high and the work efficiency is low. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned problems and provide an automatic brick plastering machine. This plastering machine can automatically plaster the upper surface of bricks and the sides of bricks. It has a high degree of automation, which can greatly improve the efficiency of plastering and reduce the labor intensity of workers.

[0005] Another object of the present invention is to provide a grouting method for an automatic brick grouting machine.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] An automatic brick plastering machine includes a material cart, a storage cavity disposed on the material cart for storing plaster, a horizontal plastering mechanism for plastering the upper surface of the bricks, a vertical plastering mechanism for plastering the sides of the bricks, and a guide mechanism for guiding the material cart to move on the bricks; wherein,

[0008] The horizontal plastering mechanism includes plastering baffles disposed on the front and rear sides of the bottom of the material cart and a horizontal plastering drive mechanism disposed on the right side of the material cart for driving the material cart to move along the upper surface of the brick; the space between the two plastering baffles forms a plastering groove, and the bottom of the material cart is provided with a plurality of connecting grooves for communicating the storage cavity with the plastering groove.

[0009] The vertical grouting mechanism includes a grouting plate, a material hopper, a vertical grouting drive mechanism, and a material picking drive mechanism, all located on the left side of the material cart. The material picking drive mechanism drives the material hopper to transport the grout from the storage chamber to the space between the grouting plate and the side of the brick. The vertical grouting drive mechanism drives the grouting plate to move upwards to apply the grout to the side of the brick.

[0010] The working principle of the above-mentioned automatic brick plastering machine is as follows:

[0011] During operation, the sides of the bricks are first coated with mortar. Specifically, a vertical mortar-coating drive mechanism drives the mortar-coating plate downwards, bringing its bottom close to the top surface of the brick. Simultaneously, a material-retrieving drive mechanism moves the material-retrieving hopper, delivering mortar from the storage chamber between the mortar-coating plate and the brick side. Then, the vertical mortar-coating drive mechanism drives the mortar-coating plate upwards, applying mortar to the brick side. At the same time, the material-retrieving drive mechanism reverses direction, moving the material-retrieving hopper back into the storage chamber to retrieve the mortar. Once the brick side is coated, the process is complete. Guided by the guiding mechanism, the horizontal grouting drive mechanism drives the material cart to move to the right along the bricklaying direction (away from the side of the brick). During the movement, the grout in the storage chamber enters the grouting groove from the connecting groove, so that the grout comes into contact with the upper surface of the brick. As the material cart moves, the grout is applied to the upper surface of the brick. After moving to a specified distance, a new brick is laid on the position where the grout has been applied, so that the sides of the brick are connected to each other and the upper and lower surfaces are connected by the grout. The above work is repeated continuously to perform grouting and bricklaying.

[0012] In a preferred embodiment of the present invention, the vertical plastering drive mechanism includes two parallel swing arms and a vertical plastering drive motor mounted on a material cart. One end of each swing arm is hinged to the plastering plate, and the other end of each swing arm is hinged to the material cart via a hinge shaft. One end of the hinge shaft is rotatably connected to the material cart, and the other end is fixed to the swing arm. The drive end of the vertical plastering drive motor is connected to one of the hinge shafts. In this mechanism, the vertical plastering drive motor drives the hinge shaft to rotate, causing the swing arms to move upward, which in turn causes the plastering plate to move upward, thus achieving plastering of the side of the brick. Specifically, when preparing to plaster, the plastering plate is located at the initial position, and in this initial position, the plastering plate is tilted upward, moving away from the side of the brick. At this time, a triangular receiving space is formed between the plastering plate and the side of the brick. During plastering, the vertical plastering drive motor drives the hinge shaft to rotate, causing the swing arms to swing upward. During the swinging process, the swing arms... The end of the boom gradually approaches the side of the brick, causing the mortar slab to move upwards and touch the side of the brick. As it approaches the side, the mortar slab swings counter-clockwise relative to the boom, gradually bringing it closer to a vertical position and squeezing the mortar in the receiving space onto the side of the brick. During the upward movement, it pushes the mortar upwards, thus better applying it to the side of the brick. As the boom continues to swing upwards, it gradually moves away from the side of the brick, moving the mortar slab away from the side, completing the mortar application on the side of the brick. In this structure, during mortar application, as the boom swings upwards and gradually approaches the side of the brick, it applies a force to the mortar slab towards the side of the brick, causing it to flip towards the side as it applies the mortar upwards, pressing the mortar firmly against the wall, thus simulating the effect of manual mortar application and achieving a good mortar application result.

[0013] Preferably, the material-retrieving drive mechanism includes a material-retrieving transmission mechanism, which includes a driving pulley, a driven pulley, and a transmission belt. The material-retrieving hopper is rotatably connected to the material cart via a rotating shaft. The driving pulley is connected to a hinge shaft away from the vertical plastering drive motor, and the driven pulley is connected to the rotating shaft. One end of the transmission belt is connected to the driving pulley, and the other end is connected to the driven pulley. In the above structure, the material-retrieving drive mechanism and the vertical plastering drive mechanism share a power source, which is a vertical plastering drive motor. During operation, the vertical plastering drive motor drives the hinge shaft to rotate, causing the swing arm to move downward, thereby causing the plastering plate to move downward until it reaches the starting position for plastering. Simultaneously with the rotation of the hinge shaft, the driving pulley rotates, which, under the transmission of the transmission belt, causes the driven pulley to rotate, thereby causing the rotating shaft to rotate. The rotating shaft causes the material-retrieving hopper, which contains plaster in the storage cavity, to swing upward and flip, pouring the plaster from the hopper into the plastering plate. The vertical grouting drive mechanism provides a receiving space between the brick and its side. During grouting, the vertical grouting drive motor drives the hinge shaft to rotate in the opposite direction, causing the swing arm to move upward, which in turn moves the grouting plate upward, applying the grout to the side of the brick. Simultaneously, the hinge shaft's reverse rotation drives the drive pulley to rotate in the opposite direction, which in turn drives the driven pulley to rotate in the opposite direction, causing the shaft to rotate in the opposite direction. This shaft then causes the grout-collecting hopper, containing grout in the storage chamber, to swing upward and flip, returning the hopper to the storage chamber. The grout in the storage chamber then enters the hopper, completing the grouting process and preparing for the next feeding. The grout-collecting drive mechanism and the vertical grouting drive mechanism share a single power source. This single power source enables synchronous movement of the grouting plate and the grout-collecting hopper, achieving the functions of grout collection and application. This greatly simplifies the mechanism, resulting in a simpler structure, significantly reducing manufacturing costs, energy consumption, and resource conservation.

[0014] Preferably, the material cart has an inclined limiting surface on its left side, which is inclined upwards away from the side of the brick; the lower back of the plastering board has an inclined surface, and the angle between the inclined surface and the plastering board is an acute angle; when the plastering board is in the starting position for plastering, the inclined surface and the inclined limiting surface are in close contact, and the plastering board is in an upward inclined state away from the side of the brick, forming a triangular receiving space between the plastering board and the side of the brick. In the above structure, when picking up material, the swing arm swings downwards, causing the plastering board to move downwards. The lower end of the plastering board will contact the inclined limiting surface. As the swing arm continues to swing downwards, the inclined surface of the plastering board will be in close contact with the inclined limiting surface, giving the plastering board a precise starting position for plastering, maintaining an inclined state, and also facilitating material receiving.

[0015] Preferably, the upper end of the plastering slab is provided with an inclined guide plate, and the angle between the inclined guide plate and the back of the plastering slab is an obtuse angle. The purpose of this is that, by setting the inclined guide plate, when the mortar is poured into the space between the plastering slab and the side of the brick, the mortar can first be guided by the inclined guide plate to flow along the front of the plastering slab, and then flow along the front of the plastering slab into the space between the plastering slab and the side of the brick. The inclined guide plate can better guide and transport the mortar.

[0016] Preferably, the front side of the grouting slab has multiple raised strips with a triangular cross-section; the multiple raised strips are evenly arranged along the width direction. By setting the raised strips, the grout will have a striped pattern after grouting, which improves the uniformity of grouting and makes it easier to connect the bricks and grout during the bricklaying process.

[0017] Preferably, the hopper includes a hopper body and a connecting plate disposed between the rotating shaft and the hopper body; wherein one end of the connecting plate is fixedly connected to the rotating shaft, and the other end of the connecting plate is fixedly connected to the hopper body. In the above mechanism, when conveying slurry, the material-receiving drive mechanism drives the rotating shaft to move, causing the connecting plate and the hopper body to swing upward and flip together, pouring the slurry between the inclined guide plate or the grouting plate and the side of the brick; after grouting is completed, the material-receiving drive mechanism drives the rotating shaft to move in the opposite direction, causing the connecting plate and the hopper body to swing upward and flip together, the hopper body falls into the storage cavity, and the slurry in the storage cavity will enter the hopper body, completing the material-receiving and preparing for the next feeding.

[0018] Preferably, the hopper body is provided with a guide plate at one end near the connecting plate. The purpose is to better guide the slurry in the hopper body to the inclined guide plate or slurry slab and the side of the brick during the tipping and unloading process.

[0019] Preferably, the grouting groove has openings at both its left and right ends, and the opening at the left end has multiple scraper teeth; the multiple scraper teeth are evenly arranged along the width direction; multiple connecting grooves are evenly arranged along the width direction, and the positions of the scraper teeth correspond one-to-one with the positions of the connecting grooves. The purpose is to improve the uniformity of grouting during the grouting process.

[0020] Preferably, the horizontal plastering drive mechanism includes a mounting plate disposed on the side of the material cart, a traveling wheel rotatably mounted on the mounting plate, and a horizontal plastering drive motor for driving the traveling wheel to rotate. The horizontal plastering drive motor drives the traveling wheel to rotate, dragging the material cart along the upper surface of the brick to complete the plastering of the upper surface of the brick.

[0021] Furthermore, the two sides of the walking wheel have a gear structure, which is intended to improve the walking wheel's ability to move on bricks.

[0022] Preferably, the guiding mechanism includes multiple guiding components, each of which includes a mounting rod disposed at the bottom of the material cart and a guide wheel disposed at the lower end of the mounting rod. By providing the guiding mechanism, the guide wheel can roll along the side of the brick, and under the action of the multiple guiding components, the material cart can be guided to move on the brick.

[0023] A method for applying mortar using an automatic brick mortar applicator includes the following steps:

[0024] (1) The vertical grouting drive motor drives the hinge shaft to rotate, which in turn drives the swing arm to swing downward. The swing arm drives the grouting board to move downward. During the downward movement of the grouting board, the lower end of the grouting board will contact the inclined limiting surface. As the swing arm continues to swing downward, the inclined surface of the grouting board will be in close contact with the inclined limiting surface, and the vertical grouting drive motor will stop driving. At this time, the grouting board has a starting position for grouting and is in an upward inclined state away from the side of the brick. A triangular receiving space is formed between the grouting board and the side of the brick. At the same time as the hinge shaft rotates, it will also drive the material picking transmission mechanism to move, thereby driving the rotating shaft to rotate. The rotating shaft will drive the material picking hopper containing grout in the storage cavity to swing upward and flip over. The grout in the material picking hopper is poured into the receiving space.

[0025] (2) The vertical grouting drive motor drives the hinge shaft to rotate in the opposite direction, causing the swing arm to swing upward. During the swing, the end of the swing arm will gradually approach the side of the brick, causing the grouting plate to move upward while approaching the side of the brick. During the process of approaching the side of the brick, the grouting plate will swing counterclockwise relative to the swing arm, so that the grouting plate will move towards a gradually vertical state, squeezing the grout in the receiving space onto the side of the brick. During the upward movement, the grout is pushed upward, thus applying the grout to the side of the brick. As the swing arm continues to swing upward, the swing arm will gradually move away from the side of the brick, causing the grouting plate to move away from the side of the brick, completing the grouting of the side of the brick. At the same time as the hinge shaft rotates in the opposite direction, it will also drive the material picking transmission mechanism to move, thereby driving the rotating shaft to rotate in the opposite direction. The rotating shaft will drive the material picking hopper to swing upward and flip, so that the material picking hopper returns to the storage cavity. The grout in the storage cavity will enter the material picking hopper, completing the material picking and preparing for the next feeding.

[0026] (3) Under the guidance of the guiding mechanism, the horizontal grouting drive mechanism drives the material cart to move to the right along the bricklaying direction. During the movement, the grout in the storage cavity will enter the grouting groove from the connecting groove, so that the grout comes into contact with the upper surface of the brick. As the material cart moves, the grout will be applied to the upper surface of the brick.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] The automatic brick plastering machine of this invention can automatically pick up materials and apply plaster to the sides of bricks through a vertical plastering mechanism; and can drive the material cart to move and apply plaster to the upper surface of bricks through a horizontal plastering mechanism. It has a high degree of automation, which can greatly improve the efficiency of plastering and reduce the labor intensity of workers. Attached Figure Description

[0038] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0039] Example 1

[0040] See Figures 1-12This embodiment discloses an automatic brick plastering machine, including a material cart 1, a storage cavity 2 disposed on the material cart 1 for storing plaster, a horizontal plastering mechanism 3 for plastering the upper surface of the brick 12, a vertical plastering mechanism 4 for plastering the sides of the brick 12, and a guide mechanism 5 for guiding the material cart 1 to move on the brick 12.

[0041] See Figures 1-12 The horizontal plastering mechanism 3 includes plastering baffles 3-1 disposed on the front and rear sides of the bottom of the material cart 1 and a horizontal plastering drive mechanism 3-2 disposed on the right side of the material cart 1 for driving the material cart 1 to move along the upper surface of the brick; the space between the two plastering baffles 3-1 forms a plastering groove 6, and the bottom of the material cart 1 is provided with a plurality of connecting grooves 7 for communicating the storage cavity 2 with the plastering groove 6.

[0042] Furthermore, the connecting groove 7 is a long strip-shaped connecting groove that extends along the length of the material cart 1. The bottom of the grouting baffle 3-1 contacts the upper surface of the brick, preventing grout from leaking onto the front and rear sides of the brick, thus providing a blocking and supporting function and enabling grout to be applied to the upper surface of the brick.

[0043] See Figures 1-12 The vertical grouting mechanism 4 includes a grouting plate 4-1, a material hopper 4-2, a vertical grouting drive mechanism 4-3, and a material picking drive mechanism 4-4, all located on the left side of the material cart 1. The material picking drive mechanism 4-4 drives the material hopper 4-2 to transport the grout from the storage chamber 2 to the space between the grouting plate 4-1 and the side of the brick. The vertical grouting drive mechanism 4-3 drives the grouting plate 4-1 to move upward to apply the grout to the side of the brick.

[0044] See Figures 1-15 The working principle of the above-mentioned automatic brick plastering machine is as follows:

[0045] During operation, the sides of the bricks are first coated with mortar. Specifically, the vertical mortar application drive mechanism 4-3 drives the mortar application plate 4-1 downwards, bringing its bottom close to the upper surface of the brick. Simultaneously, the material handling drive mechanism 4-4 drives the material handling hopper 4-2 to transport the mortar from the storage chamber 2 between the mortar application plate 4-1 and the side of the brick. Then, the vertical mortar application drive mechanism 4-3 drives the mortar application plate 4-1 upwards, applying the mortar to the side of the brick. At the same time, the material handling drive mechanism 4-4 reverses the direction of the material handling hopper 4-2, returning it to the storage chamber. In step 2, material is taken out; after the side of the brick is coated, under the guidance of the guide mechanism 5, the horizontal grouting drive mechanism 3-2 drives the material cart 1 to move to the right along the bricklaying direction. During the movement, the grout in the storage cavity 2 will enter the grouting groove 6 from the connecting groove 7, so that the grout comes into contact with the upper surface of the brick. As the material cart 1 moves, the grout will be coated onto the upper surface of the brick. After moving to the specified distance, a new brick is laid on the position coated with grout, so that the sides of the brick are connected to each other and the upper and lower surfaces are connected by grout. The above work is repeated continuously to perform grouting and bricklaying.

[0046] See Figures 1-15The vertical plastering drive mechanism 4-3 includes two parallel swing arms 4-31 and a vertical plastering drive motor 4-32 mounted on the material cart 1. One end of each swing arm 4-31 is hinged to the plastering plate 4-1, and the other end of each swing arm 4-31 is hinged to the material cart 1 via a hinge shaft 4-33. One end of the hinge shaft 4-33 is rotatably connected to the material cart 1, and the other end of the hinge shaft 4-33 is fixed to the swing arm 4-31. The drive end of the vertical plastering drive motor 4-32 is connected to one of the hinge shafts 4-33. In the aforementioned mechanism, the vertical grouting drive motor 4-32 drives the hinge shaft 4-33 to rotate, causing the swing arm 4-31 to move upward, which in turn causes the grouting plate 4-1 to move upward, thus achieving grouting on the side of the brick. Specifically, when preparing to grout, the grouting plate 4-1 is located at the starting position for grouting. At the starting position, the grouting plate 4-1 is in an inclined state, tilting upward in a direction away from the side of the brick. At this time, a triangular receiving space 14 is formed between the grouting plate 4-1 and the side of the brick 12. During grouting, the vertical grouting drive motor 4-32 drives the hinge shaft 4-33 to rotate, causing the swing arm 4-31 to swing upward. During the movement, the end of the swing arm 4-31 gradually approaches the side of the brick, causing the grouting plate 4-1 to move upwards and approach the side of the brick. As it approaches the side of the brick, the grouting plate 4-1 swings counterclockwise relative to the swing arm 4-31, causing the grouting plate 4-1 to gradually become more vertical, squeezing the grout in the receiving space 14 onto the side of the brick. During the upward movement, the grout is pushed upwards, thus better applying the grout to the side of the brick. As the swing arm 4-31 continues to swing upwards, it gradually moves away from the side of the brick, causing the grouting plate 4-1 to move away from the side of the brick, completing the grouting of the side of the brick. In the above structure, during grouting, the swing arm 4-31 swings upwards and gradually approaches the side of the brick. The swing arm 4-31 applies a force to the grouting plate 4-1 towards the side of the brick, causing the grouting plate to flip towards the side of the brick as it applies the grout upwards, thus adhering the grout tightly to the wall. This simulates the effect of manual grouting, resulting in a good grouting effect. When the swing arm 4-31 swings to a horizontal position, the distance between the end of the swing arm 4-31 and the side of the brick is the shortest.

[0047] The two hinge shafts 4-33 are located on the same axis, which ensures that the two swing arms 4-31 swing synchronously. At the same time, it can also prevent the plastering plate 4-1 from getting dry with the hinge shaft 4-33 during the movement.

[0048] See Figures 1-15The material picking drive mechanism 4-4 includes a material picking transmission mechanism, which includes a driving pulley 4-41, a driven pulley 4-42, and a transmission belt 4-43. The material picking hopper 4-2 is rotatably connected to the material cart 1 via a rotating shaft 4-44. The driving pulley 4-41 is connected to a hinge shaft 4-33 away from the vertical grouting drive motor 4-32, and the driven pulley 4-42 is connected to the rotating shaft 4-44. One end of the transmission belt 4-43 is connected to the driving pulley 4-41, and the other end of the transmission belt 4-43 is connected to the driven pulley 4-42. In the above structure, the material-retrieving drive mechanism 4-4 and the vertical grouting drive mechanism 4-3 share a common power source, which is the vertical grouting drive motor 4-32. During operation, the vertical grouting drive motor 4-32 drives the hinge shaft 4-33 to rotate, causing the swing arm 4-31 to move downwards, thereby causing the grouting plate 4-1 to move downwards until it reaches the position ready for grouting. Simultaneously, the hinge shaft 4-33 rotates, driving the drive pulley 4-41 to rotate. Driven by the transmission belt 4-43, this drives the driven pulley 4-42 to rotate, thereby driving the rotating shaft 4-44 to rotate. The rotating shaft 4-44 then causes the material-retrieving hopper 4-2, which contains grout in the storage cavity 2, to swing upwards and flip, pouring the grout from the hopper 4-2 into the grouting plate. Between the mortar plate 4-1 and the side of the brick; during mortar application, the vertical mortar application drive motor 4-32 drives the hinge shaft 4-33 to rotate in the opposite direction, causing the swing arm 4-31 to move upward, thereby causing the mortar plate 4-1 to move upward and apply the mortar to the side of the brick; at the same time as the hinge shaft 4-33 rotates in the opposite direction, it will drive the drive pulley 4-41 to rotate in the opposite direction, and under the transmission belt 4-43, it will drive the driven pulley 4-42 to rotate in the opposite direction, thereby driving the rotating shaft 4-44 to rotate in the opposite direction. The rotating shaft 4-44 will drive the hopper 4-2 containing mortar in the storage cavity 2 to swing upward and flip, so that the hopper 4-2 returns to the storage cavity 2, and the mortar in the storage cavity 2 will enter the hopper 4-2, completing the retrieval and preparing for the next feeding. The material picking drive mechanism 4-4 and the vertical grouting drive mechanism 4-3 share a power source. Through a single power source, the grouting plate 4-1 and the material picking hopper 4-2 can move synchronously, thereby realizing the functions of picking up materials and grouting. This greatly simplifies the mechanism, makes the structure simpler, significantly reduces manufacturing costs, reduces energy consumption, and saves resources.

[0049] See Figures 1-15The material cart 1 has an inclined limiting surface 13 on its left side, which is inclined upward in a direction away from the side of the brick; the mortar board 4-1 has an inclined surface 4-131 at the lower back end, and the angle between the inclined surface 4-131 and the mortar board 4-1 is an acute angle; when the mortar board 4-1 is in the starting position for preparing to apply mortar, the inclined surface 4-131 and the inclined limiting surface 13 are in close contact with each other. At this time, the mortar board 4-1 is in an upward inclined state in a direction away from the side of the brick, and a triangular receiving space 14 is formed between the mortar board 4-1 and the side of the brick. In the above structure, when picking up materials, the swing arm 4-31 swings downward, causing the grouting plate 4-1 to move downward. The lower end of the grouting plate 4-1 will contact the inclined limiting surface 13. As the swing arm 4-31 continues to swing downward, the inclined surface 4-131 of the grouting plate 4-1 will be in close contact with the inclined limiting surface 13, so that the grouting plate 4-1 has a precise starting position for preparing to apply grout, maintaining an inclined state, and also facilitating material reception.

[0050] See Figures 1-15 The plastering slab 4-1 has mounting portions 4-13 on both sides of its back side, and the inclined surface 4-131 is provided on the mounting portion 4-13. The swing arm 4-31 is hinged to the mounting portion 4-13. The purpose is to facilitate the connection between the swing arm 4-31 and the plastering slab 4-1, and at the same time ensure that the plastering slab 4-1 has a precise starting position for plastering.

[0051] See Figure 11 The material cart 1 is provided with a protective cover 8 on its side, and the material picking drive mechanism 4-4 is disposed inside the protective cover 8. The purpose is to protect the material picking drive mechanism 4-4 and prevent slurry from entering the material picking drive mechanism 4-4.

[0052] See Figures 4-11 The upper end of the plastering board 4-1 is provided with an inclined guide plate 4-11, and the angle between the inclined guide plate 4-11 and the back of the plastering board 4-1 is an obtuse angle. The purpose is that, by setting the inclined guide plate 4-11, when the hopper 4-2 pours the plastering board 4-1 between the plastering board 4-1 and the side of the brick, the plaster can first be guided by the inclined guide plate 4-11, allowing the plaster to flow along the inclined guide plate 4-11 into the front of the plastering board 4-1, and then flow along the front of the plastering board 4-1 into the space between the plastering board 4-1 and the side of the brick. The inclined guide plate 4-11 can better guide and transport the plaster.

[0053] See Figures 4-11The plastering board 4-1 has multiple raised strips 4-12 with triangular cross-sections on its front side; the multiple raised strips 4-12 are evenly arranged along the width direction. By setting the raised strips 4-12, the plastering board 4-1 will have striped patterns on the mortar after plastering, which improves the uniformity of plastering and makes it easier to connect the bricks and mortar during the bricklaying process.

[0054] The plastering board 4-1, the raised strip 4-12, the inclined guide plate 4-11, and the mounting part 4-13 are integrated into one unit.

[0055] See Figures 4-11 The material hopper 4-2 includes a hopper body 4-21 and a connecting plate 4-22 disposed between the rotating shaft 4-44 and the hopper body 4-21; wherein, one end of the connecting plate 4-22 is fixedly connected to the rotating shaft 4-44, and the other end of the connecting plate 4-22 is fixedly connected to the hopper body 4-21. In the above mechanism, when conveying slurry, the material-receiving drive mechanism 4-4 drives the rotating shaft 4-44 to move, causing the connecting plate 4-22 and the hopper body 4-21 to swing upward and flip together, pouring the slurry into the inclined guide plate 4-11 or between the slurry plastering plate 4-1 and the side of the brick; after the slurry is applied, the material-receiving drive mechanism 4-4 drives the rotating shaft 4-44 to move in the opposite direction, causing the connecting plate 4-22 and the hopper body 4-21 to swing upward and flip together, and the hopper body 4-21 falls into the storage cavity 2, and the slurry in the storage cavity 2 will enter the hopper body 4-21, completing the material receivable and preparing for the next material delivery.

[0056] See Figures 4-11 The hopper 4-21 has a guide plate 4-23 on one end near the connecting plate 4-22. The purpose is to better guide the slurry in the hopper 4-21 to the inclined guide plate 4-11 or the slurry plate 4-1 and the side of the brick during the tipping and pouring process.

[0057] See 2- Figure 12 The material cart 1 has an installation space 9 on its left side, which is used to place the swing arm 4-31 and the plastering board 4-1; the inclined limiting surface 13 forms a wall of the installation space 9. In the above structure, the installation space 9 makes the structure more compact, while also ensuring that the swing arm 4-31 and the plastering board 4-1 have sufficient room to move. The cross-section of the installation space 9 is an inverted triangle, which further makes the structure more compact.

[0058] See 1- Figure 11The grouting groove 6 has openings 10 at both its left and right ends. Multiple scraper teeth 11 are provided on the opening 10 at the left end. These scraper teeth 11 are evenly arranged along the width direction (front-to-back direction). Multiple connecting grooves 7 are also evenly arranged along the width direction, with the positions of the scraper teeth 11 corresponding one-to-one with the positions of the connecting grooves 7. The purpose of this is to improve the uniformity of the grouting process.

[0059] The number of the connecting grooves 7 is 6, and the number of the scraping teeth 11 is also 6.

[0060] See 1- Figure 12 The horizontal plastering drive mechanism 3-2 includes a mounting plate 3-21 disposed on the right side of the material cart 1, a traveling wheel 3-22 rotatably mounted on the mounting plate 3-21, and a horizontal plastering drive motor 3-23 for driving the traveling wheel 3-22 to rotate. The horizontal plastering drive motor 3-23 drives the traveling wheel 3-22 to rotate, dragging the material cart 1 along the upper surface of the brick to complete the plastering of the upper surface of the brick.

[0061] Both the vertical plastering drive motor 4-32 and the horizontal plastering drive motor 3-23 are stepper motors.

[0062] See 1- Figure 12 The walking wheels 3-22 have gear structures on both sides, which are intended to improve the walking ability of the walking wheels 3-22 on bricks.

[0063] See 1- Figure 12 The guiding mechanism 5 includes multiple guiding components, each of which includes a mounting rod 5-1 disposed at the bottom of the material cart 1 and a guide wheel 5-2 disposed at the lower end of the mounting rod 5-1. By setting the guiding mechanism 5, the guide wheel 5-2 can roll along the side of the brick, and under the action of the multiple guiding components, the material cart 1 can be guided to move on the brick.

[0064] There are four guide components, which are distributed on the outside of the plastering groove 6.

[0065] Example 2

[0066] See Figures 1-15 This embodiment discloses a grouting method for an automatic brick grouting machine, including the following steps:

[0067] (1) The vertical plastering drive motor 4-32 drives the hinge shaft 4-33 to rotate, causing the swing arm 4-31 to swing downwards; the swing arm 4-31 drives the plastering plate 4-1 to move downwards. During the downward movement of the plastering plate 4-1, the lower end of the plastering plate 4-1 will contact the inclined limiting surface 13. As the swing arm 4-31 continues to swing downwards, the inclined surface 4-131 of the plastering plate 4-1 will be in close contact with the inclined limiting surface 13, stopping the drive of the vertical plastering drive motor 4-32. At this time, the plastering plate 4-1 has The starting position for applying mortar is tilted upwards in a direction away from the side of the brick (to the right), forming a triangular receiving space 14 between the mortar application board 4-1 and the side of the brick. As the hinge shaft 4-33 rotates, it also drives the material handling transmission mechanism to move, thereby driving the rotating shaft 4-44 to rotate. The rotating shaft 4-44 will cause the material handling hopper 4-2, which contains mortar in the storage cavity 2, to swing upwards and flip over, and the mortar in the material handling hopper 4-2 will be poured into the receiving space 14.

[0068] (2) The vertical grouting drive motor 4-32 drives the hinge shaft 4-33 to rotate in the opposite direction, causing the swing arm 4-31 to swing upward. During the swinging process, the end of the swing arm 4-31 will gradually approach the side of the brick, causing the grouting plate 4-1 to move upward while approaching the side of the brick. During the process of approaching the side of the brick, the grouting plate 4-1 will swing counterclockwise (flip to the left) relative to the swing arm 4-31, so that the grouting plate 4-1 will move towards a gradually vertical state, squeezing the grout in the receiving space 14 onto the side of the brick; during the upward movement, the grout is also squeezed into the brick. The material is pushed upwards, thus applying the slurry to the side of the brick. As the swing arm 4-31 continues to swing upwards, it gradually moves away from the side of the brick, causing the slurry application plate 4-1 to move away from the side of the brick, completing the slurry application on the side of the brick. At the same time, the hinge shaft 4-33 rotates in the opposite direction, which also drives the material picking transmission mechanism to move, thereby driving the rotating shaft 4-44 to rotate in the opposite direction. The rotating shaft 4-44 will drive the material picking hopper 4-2 to swing upwards and flip over, so that the material picking hopper 4-2 returns to the storage cavity 2. The slurry in the storage cavity 2 will enter the material picking hopper 4-2, completing the material picking and preparing for the next feeding.

[0069] (3) Under the guidance of the guide mechanism 5, the horizontal grouting drive mechanism 3-2 drives the material cart 1 to move to the right along the bricklaying direction (to the right). During the movement, the grout in the storage cavity 2 will enter the grouting groove 6 from the connecting groove 7, so that the grout comes into contact with the upper surface of the brick. As the material cart 1 moves, the grout will be applied to the upper surface of the brick.

[0070] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.

As the swing arm continues to swing downward, the inclined surface of the grouting board will be in close contact with the inclined limiting surface, and the vertical grouting drive motor will stop driving. At this time, the grouting board has a starting position for grouting and is in an upward inclined state away from the side of the brick. A triangular receiving space is formed between the grouting board and the side of the brick. While the hinge shaft rotates, it will also drive the material picking transmission mechanism to move, thereby driving the rotating shaft to rotate.
