Description

Technical Field

[0001] This invention belongs to the field of building construction. More specifically, this invention relates to an automated slurry-spraying device and its slurry-spraying method. Background Technology

[0002] Before applying mortar to concrete or brick walls, the smooth surface needs to be roughened to increase its roughness. This provides adhesion points for the plaster layer, increasing its adhesion and ensuring a firm bond between the plaster and the wall, preventing hollow areas or complete detachment of the plaster. Currently, roughening methods typically involve manual patting or using a roughening machine. Manual patting, such as the integrated patting and roughening mesh disclosed in patent publication number CN218581111U, suffers from high labor requirements, slow construction speed, and high construction costs. Roughening with a roughening machine, such as a wall roughening sprayer disclosed in patent publication number CN219027184U, produces a circular arc-shaped spray of mortar on the wall surface, but this also presents the problem of insufficient adhesion during plastering. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0004] One object of the present invention is to provide an automated slurry-spraying device that can pat and spray slurry onto a wall surface, thereby satisfying the wall surface roughness requirements while increasing construction speed and reducing construction costs.

[0005] To achieve these objectives and other advantages of the present invention, an automated slurry-throwing device is provided, comprising:

[0006] Movable walking mechanism;

[0007] A storage bin is positioned above the movable walking mechanism;

[0008] The slurry-throwing mechanism includes a slurry-throwing box and a swinging mechanism. The slurry-throwing box is connected to the storage box through a feeding mechanism. The swinging mechanism is mounted on the movable walking mechanism. The slurry-throwing box is mounted on the swinging mechanism. The side of the slurry-throwing box away from the swinging mechanism is a wire mesh.

[0009] The material supply mechanism transports the material from the storage bin to the slurry box. The slurry box contacts the wall surface under the swing of the swinging structure, thus patting and roughening the wall surface.

[0010] Preferably, the swing mechanism includes:

[0011] The lifting mechanism includes a first motor, a first lead screw, a first sliding block, and a support frame. The support frame has an inverted U-shaped structure and is vertically mounted on the movable walking mechanism. A first sliding groove is provided on the inner side of the support frame. The first sliding block slides in conjunction with the first sliding groove. A first threaded hole is provided in the middle of the first sliding block. The first threaded hole is threaded in conjunction with the first lead screw. The first motor is mounted on the support frame and connected to the first lead screw to drive the first lead screw to rotate.

[0012] A swing arm, which is hinged to a first sliding block, and the paddle box is disposed on the swing arm;

[0013] The cylinder has its fixed end hinged to the first slider and its movable end hinged to the swing arm.

[0014] Preferably, the support frame is located at the front center of the movable walking mechanism and is rotatably connected to the movable walking mechanism. The swing arm includes a fixed part and a connecting part. The connecting part is made of elastic material. Both ends of the fixed part are provided with a first internal thread, and one end of the connecting part is provided with a first external thread. The first internal thread and the first external thread are threaded together to connect and fix the connecting part and the fixed part. The fixed part is hinged to the upper end of the first sliding block. The fixed end of the cylinder is hinged to the lower end of the first sliding block. The movable end of the cylinder is hinged to the lower end of the fixed part. The slurry box is located in the movable part.

[0015] When applying mortar to a high wall surface, the upper end of the connecting part is connected to the upper end of the fixing part. When the movable end of the cylinder extends, it drives the upper end of the fixing part to rotate downward, causing the mortar-applying box to rotate and pat the wall surface.

[0016] When applying mortar to a low wall surface, the support frame rotates 180°, connecting the lower end of the connecting part to the lower end of the fixed part. When the movable end of the cylinder extends, it drives the lower end of the fixed part to rotate upward, causing the mortar-applying box to rotate and pat the wall surface.

[0017] Preferably, the connecting part is a retractable structure.

[0018] Preferably, the connecting part has a Y-shaped structure, and the pulping box is disposed on the two free ends at the upper end of the connecting part.

[0019] Preferably, the distance between the two free ends of the paddle-beating box is equal to the width of the paddle-beating box, and the front end of the movable walking mechanism is provided with a sliding mechanism, the sliding mechanism comprising:

[0020] The second chute is located at the front end of the movable walking mechanism;

[0021] The second sliding block is in sliding engagement with the second sliding groove;

[0022] The second lead screw is threadedly connected to the second threaded hole on the second sliding block;

[0023] The second motor is connected and fixed to the second lead screw to drive the second lead screw to rotate;

[0024] The sliding distance of the second sliding block is equal to the width of the pulping box.

[0025] Preferably, the bottom of the storage box is a conical structure, the feeding mechanism includes a screw and a conveying cylinder, the screw is disposed in the conveying cylinder, the inlet is provided above the beginning of the conveying cylinder and the inlet is connected to the storage box, and the outlet is at the end of the conveying cylinder and is connected to the slurry box through a pipe.

[0026] Preferably, a pressure sensor is provided at the bottom of the slurry box. When the pressure in the slurry box is less than a preset value, the feeding mechanism delivers slurry to the slurry box; when the pressure in the slurry box is greater than the preset value, the feeding mechanism stops delivering slurry to the slurry box.

[0027] Preferably, it also includes a slurry-spraying recognition and control system for identifying and positioning the wall surface, the movable walking mechanism, the cylinder, the lifting mechanism, and the sliding mechanism.

[0028] The method for displacing slurry using an automated slurry dispensing device includes the following steps:

[0029] 1) Add slurry to the storage tank, move the device to the wall to be slurryed, and the feeding mechanism delivers slurry to the slurry box;

[0030] 2) When applying mortar to a high wall surface, the cylinder extends and drives the upper end of the connecting part to rotate downwards, causing the mortar-applying box to pat the wall surface. The second motor drives the second sliding block to move, thereby moving the support frame. The distance the support frame moves is equal to the width of the mortar-applying box. The cylinder extends and drives the upper end of the connecting part to rotate downwards again to complete the patting and mortar-applying action. After the mortar-applying box completes two patting actions, the first motor drives the first sliding block to move downwards, with the distance the first sliding block moves being equal to the height of the mortar-applying box. The cylinder extends and drives the connecting part to rotate, causing the mortar-applying box to pat the wall surface. This process is repeated to pat the wall surface to the bottom of the upper part. The movable walking mechanism moves one mortar-applying box forward along the wall surface. The cylinder extends and drives the upper end of the connecting part to rotate downwards, causing the slurry-spraying box to slap the wall. The second motor drives the second sliding block to move, thereby moving the support frame. The distance the support frame moves is equal to the width of the slurry-spraying box. The cylinder extends and drives the upper end of the connecting part to rotate downwards again, completing the slapping and slurry-spraying action. After the slurry-spraying box completes two slaps, the first motor drives the first sliding block to move upwards. The distance the first sliding block moves is equal to the height of the slurry-spraying box. The cylinder extends and drives the connecting part to rotate, causing the slurry-spraying box to slap the wall. This process is repeated to slap and spray slurry to the top of the upper part of the wall. The slapping and slurry-spraying trajectory is S-shaped to complete the slapping and slurry-spraying of the upper part of the wall.

[0031] 3) When applying mortar to a lower part of the wall, rotate the support frame 180° and connect the mortar-applying box to the lower end of the connecting part. Adjust the height of the lifting mechanism so that the mortar-applying box is below the upper part of the wall that has already been mortared. Extend the cylinder to drive the upper end of the connecting part to rotate downward so that the mortar-applying box pats the wall. The second motor drives the second sliding block to move, thereby moving the support frame. The distance the support frame moves is equal to the width of the mortar-applying box. Extend the cylinder to drive the upper end of the connecting part to rotate downward again to complete the mortar-applying action. After the mortar-applying box completes two pats, the first motor drives the first sliding block to move downward. The distance the first sliding block moves is equal to the height of the mortar-applying box. Extend the cylinder to drive the connecting part to rotate so that the mortar-applying box pats the wall. Repeat this process to mortar-apply to the lower part of the wall. At the bottom of a portion of the wall; a movable walking mechanism moves forward along the wall a distance equal to the width of a mortar-spraying box. An extended cylinder drives the upper end of the connecting part to rotate downwards, causing the mortar-spraying box to slap the wall. A second motor drives a second sliding block to move, causing a support frame to move. The support frame moves a distance equal to the width of the mortar-spraying box. The extended cylinder then drives the upper end of the connecting part to rotate downwards again, completing the slapping and mortar-spraying action. After the mortar-spraying box completes two slaps, a first motor drives a first sliding block to move upwards, the first sliding block moving a distance equal to the height of the mortar-spraying box. The extended cylinder then drives the connecting part to rotate, causing the mortar-spraying box to slap the wall. This process is repeated to slap and spray mortar to the top of the lower portion of the wall, creating an S-shaped slapping and mortar-spraying trajectory to complete the slapping and spraying of the lower portion of the wall.

[0032] The present invention has at least the following beneficial effects:

[0033] First, the present invention uses the swing arm to drive the slurry box to make a slapping action, so as to throw the slurry temporarily stored in the slurry box out from the metal mesh at the front end of the slurry box and stick it to the wall surface, thereby realizing the slapping and roughening treatment of the wall surface.

[0034] Secondly, the present invention provides two slurry-spraying boxes at the upper end of the Y-shaped connection. By slurry-spraying once, the wall surface of the two slurry-spraying boxes can be slurried, thus improving the efficiency of slurry-spraying.

[0035] Third, after one patting and splashing operation, the sliding mechanism moves the patting box by the width of one patting box. The swing arm then moves the patting box to swing again, performing a patting action. Subsequently, the lifting mechanism rises or falls, causing the patting box to rise or fall, completing the patting and splashing of one wall surface. Then, the movable walking mechanism moves to the next wall surface requiring patting and splashing, thus automatically and continuously achieving patting and splashing of the wall surface. This invention, through two patting and splashing operations, covers a wall surface width equivalent to four patting boxes, improving the efficiency of patting and splashing. Furthermore, the sliding mechanism moves the patting box, reducing the number of movements of the movable walking mechanism and decreasing the energy consumed by its movement.

[0036] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0044] like Figure 1-2 As shown, the present invention provides an automated slurry-throwing device, which includes:

[0045] Mobile walking mechanism 1;

[0046] Storage box 2 is located above the movable walking mechanism 1;

[0047] The slurry-throwing mechanism includes a slurry-throwing box 3 and a swinging mechanism. The slurry-throwing box 3 is connected to the storage box 2 through a feeding mechanism 7. The swinging mechanism is mounted on the movable walking mechanism 1. The slurry-throwing box 3 is mounted on the swinging mechanism. The side of the slurry-throwing box 3 away from the swinging mechanism is a wire mesh.

[0048] The feeding mechanism 7 delivers the material from the storage box 2 to the slurry box 3. The slurry box 3 contacts the wall surface under the swing of the swing structure, thus patting and roughening the wall surface.

[0049] In this technical solution, the movable walking mechanism 1 can move forward, backward, left, or right. The movable walking mechanism 1 can also be equipped with an automatic walking system to automatically avoid obstacles and autonomously plan its route. The cross-section of the storage box 2 can be circular, rectangular, or square. The cross-section of the slurry-beating box 3 can be triangular, circular, or rectangular, preferably rectangular. The slurry-beating box 3 is a cuboid box with a metal mesh on one side, allowing it to communicate with the outside world through the mesh openings. When the swinging mechanism swings, the slurry-beating box 3 strikes the wall surface, meaning the metal mesh side contacts the wall, and the slurry inside the slurry-beating box 3 is thrown out and adheres to the wall surface. As the slurry-beating box 3 continues to beat, the amount of slurry inside decreases, and the feeding mechanism 7 supplies slurry to the slurry-beating box 3. The feeding mechanism 7 can be a conveying screw or a conveying pump, etc.

[0050] In another technical solution, the swing mechanism includes:

[0051] The lifting mechanism includes a first motor, a first lead screw, a first sliding block, and a support frame 4. The support frame 4 has an inverted U-shaped structure and is vertically mounted on the movable walking mechanism 1. A first sliding groove is provided on the inner side of the support frame 4. The first sliding block slides in the first sliding groove. A first threaded hole is provided in the middle of the first sliding block. The first threaded hole is threaded in the first lead screw. The first motor is mounted on the support frame 4 and connected to the first lead screw to drive the first lead screw to rotate.

[0052] The swing arm 5 is hinged to the first sliding block, and the paddle box 3 is disposed on the swing arm 5;

[0053] The cylinder 6 has its fixed end hinged to the first slider, and its movable end hinged to the swing arm 5.

[0054] In this technical solution, the lifting mechanism drives the swing arm 5 to move up and down, realizing the patting and splashing of mortar on the wall surface at different heights. The cylinder 6 drives the swing arm 5 to swing up and down so that the mortar-splashing box 3 can complete the patting action on the wall surface.

[0055] In another technical solution, the support frame 4 is located at the front middle of the movable walking mechanism 1 and is rotatably connected to the movable walking mechanism 1. The swing arm 5 includes a fixed part and a connecting part 8. The connecting part 8 is made of elastic material. Both ends of the fixed part are provided with a first internal thread. One end of the connecting part 8 is provided with a first external thread. The first internal thread and the first external thread are threaded together to connect and fix the connecting part 8 to the fixed part. The fixed part is hinged to the upper end of the first sliding block. The fixed end of the cylinder 6 is hinged to the lower end of the first sliding block. The movable end of the cylinder 6 is hinged to the lower end of the fixed part. The slurry box 3 is located in the movable part.

[0056] When applying mortar to a high wall surface, the connecting part 8 is connected to the upper end of the fixing part. When the movable end of the cylinder 6 extends, it drives the upper end of the fixing part to rotate downward, causing the mortar-applying box 3 to rotate and pat the wall surface.

[0057] When applying mortar to a low wall surface, the support frame 4 rotates 180°, the connecting part 8 connects to the lower end of the fixed part, and when the movable end of the cylinder 6 extends, it drives the lower end of the fixed part to rotate upward, causing the mortar-applying box 3 to rotate and pat the wall surface.

[0058] In this technical solution, when the slurry application proceeds from low to high, the lifting mechanism drives the slurry box 3 to move upwards. Specifically, the cylinder 6 drives the swing arm 5 to rotate the slurry box 3 to complete one slurry application. Then, the lifting mechanism moves upwards by a distance equal to the length of the slurry box 3, so that the lower end of the slurry box 3 is above and adjacent to the upper edge of the previous slurry application mark. This process of slurry application and slurry application is repeated until the top of the wall is reached. After reaching the top, the movable walking mechanism 1 moves to the side of the wall that has not been slurred by a distance equal to the width of the slurry box 3. The cylinder 6 drives the swing arm 5 to rotate the slurry box 3 to complete one slurry application. Then, the lifting mechanism moves downwards by a distance equal to the length of the slurry box 3, so that the upper end of the slurry box 3 is below and adjacent to the lower edge of the previous slurry application mark. This process of slurry application and slurry application is repeated until the bottom of the wall is reached. The slurry application marks are S-shaped, completing the slurry application and roughening of the wall surface. Since the swing arm 5 is initially tilted upwards, even when the first sliding block of the lifting mechanism is at its lowest point, there is still a situation where some wall below the slurry box 3 cannot be slurried and splashed. To solve this problem, the present invention changes the direction of the swing arm 5 by rotating the support frame 4, that is, by tilting the swing arm 5 downwards so that the slurry box 3 can slurry the wall surface at a lower height.

[0059] In another technical solution, the connecting part 8 is a telescopic structure. In this technical solution, the telescopic structure can be a sleeve-type telescopic structure, fixed with positioning protrusions or bolts, or it can be an electrically operated telescopic structure. This application does not limit the telescopic structure, as long as it can achieve length adjustment. The telescopic nature of the connecting part 8 can expand the range of slapping and splashing.

[0060] In another technical solution, the connecting part 8 has a Y-shaped structure, and the slurry-spraying box 3 is disposed on the two free ends of the upper part of the connecting part 8. The presence of two slurry-spraying boxes 3 on the connecting part 8 improves the efficiency of slurry spraying.

[0061] In another technical solution, the distance between the two free ends of the plucking boxes 3 is equal to the width of the plucking boxes 3, and the front end of the movable walking mechanism 1 is provided with a sliding mechanism, the sliding mechanism including:

[0062] The second slide is located at the front end of the movable walking mechanism 1;

[0063] The second sliding block is in sliding engagement with the second sliding groove;

[0064] The second lead screw is threadedly connected to the second threaded hole on the second sliding block;

[0065] The second motor is connected and fixed to the second lead screw to drive the second lead screw to rotate;

[0066] The sliding distance of the second sliding block is equal to the width of the paddle box 3.

[0067] In this technical solution, after the slurry box 3 completes one slurry application, the sliding mechanism drives the swing arm 5 to move and complete the slurry application again. That is, through two slurry applications, the width of the roughened wall surface is 4 times the width of the slurry box 3, which improves the efficiency of slurry application. The lifting mechanism moves up or down, and the moving distance is the length of the slurry box 3. The above actions are repeated to complete the slurry application.

[0068] In another technical solution, the bottom of the storage tank 2 is a conical structure, the feeding mechanism 7 includes a screw and a conveying cylinder, the screw is disposed in the conveying cylinder, the beginning of the conveying cylinder is provided with a feed inlet, the feed inlet is connected to the storage tank 2, and the end of the conveying cylinder is a discharge port, which is connected to the slurry box 3 through a pipe.

[0069] In this technical solution, the slurry in the storage tank 2 enters the conveying cylinder through the feed inlet. The slurry is squeezed by the screw in the conveying cylinder and output from the discharge port at the end, and then transported to the slurry box 3 through the pipeline.

[0070] In another technical solution, a pressure sensor is provided in the slurry box 3. When the pressure in the slurry box 3 is less than a preset value, the feeding mechanism 7 feeds slurry into the slurry box 3; when the pressure in the slurry box 3 is greater than the preset value, the feeding mechanism 7 stops feeding slurry into the slurry box 3.

[0071] In this technical solution, as the slurry-beating and slurry-throwing of the slurry-beating box 3 continues, the slurry in the slurry-beating box 3 decreases, and the pressure value sensed by the pressure sensor decreases. At this time, the feeding mechanism 7 is activated to replenish the slurry in the slurry-beating box 3 in a timely manner.

[0072] In another technical solution, such as Figure 3 As shown, the inside of the slurry box is provided with several guide components 10, all of which are located to the right of the feed port 14 at the lower end of the slurry box. The cross-section of the guide component 10 is triangular. The several guide components 10 are spaced apart along the length of the slurry box to form a guide channel 11 between two adjacent guide components 10. The pressure sensor includes a first pressure sensor 12 and a second pressure sensor 13. The first pressure sensor 12 is located at the lower end of the slurry box, and the second pressure sensor 13 is located at the upper end of the slurry box. When the difference between the pressure detected by the first pressure sensor 12 and the pressure detected by the second pressure sensor 13 is greater than a preset pressure value, the feeding mechanism feeds material to the slurry box.

[0073] When the slurry delivered by the feeding mechanism is delivered to the slurry-pressing box, it enters the box through the feed port 14 at the bottom. Due to the viscous nature of the slurry, the pressure at the bottom of the box continuously increases as it moves from the bottom to the top, causing it to overflow from the metal mesh at the bottom during filling. In this technical solution, several guide members 10 are provided, forming a slurry supply channel 9 on the left side of each guide member 10. Due to the obstruction effect of the guide members 10, the slurry moves from the bottom to the top of the supply channel. The slurry in the supply channel 9 is distributed to the right side of the guide members 10 via the guide channel 11 to store slurry for the pressing process. The slurry distribution function of the guide members 10 reduces the pressure of the slurry between the guide members 10 and the metal mesh at the bottom of the slurry-pressing box, thereby effectively reducing the amount of slurry overflowing from the metal mesh.

[0074] In another technical solution, to facilitate more intelligent slapping and splashing of the paddle, a paddle splashing recognition and control system is also included to control the movable walking mechanism 1, the cylinder 6, the lifting mechanism, and the sliding mechanism; the control method of the paddle splashing recognition and control system includes the following steps:

[0075] Step 1: When the storage tank 2 is full, the feeding mechanism 7 supplies slurry to the slurry box 3. When the pressure sensor detects that the pressure in the slurry box 3 is greater than the preset value, the controller stops the feeding mechanism 7 from supplying slurry.

[0076] Step 2: The controller controls the cylinder 6 to extend, and the swing arm 5 swings downward to complete one beat; the controller controls the cylinder 6 to retract to control the swing arm 5 to swing upward, and at the same time the controller controls the sliding mechanism to slide a distance equal to the width of the beater box 3. After the sliding mechanism finishes sliding, the controller controls the cylinder 6 to extend to complete one beat.

[0077] Step 3: The controller controls the first slider of the lifting mechanism to rise to a height equal to the length of the slurry box 3, and repeats the operation of Step 2 to slap and splash slurry onto the wall.

[0078] Step 4: Repeat the operation of Step 3 until the slurry is patted and splashed to the top of the wall. Then, the controller controls the movable walking mechanism 1 to move along the wall. The moving distance is the width of 3 slurry patting boxes 3. Repeat Step 2.

[0079] Step 5: The controller controls the first slider of the lifting mechanism to descend by the length of the paddle box 3, and repeats Step 2;

[0080] Step 6: Repeat step 5 until the bottom of the wall surface that can be patted and splashed with mortar. Then, the controller controls the movable walking mechanism 1 to move along the wall surface, and the moving distance is the width of 3 mortar-splashing boxes 3.

[0081] Step 7: Repeat steps 2, 3, 4, 5, and 6 to pat and roughen the upper un-splashed wall surface, making the patting trajectory S-shaped; remove the connecting part 8, control the support frame 4 to rotate 180°, then connect the connecting part 8 to the lower end of the fixed part, and adjust the height of the first sliding block in the lifting mechanism so that the patting box 3 is located below the patting trace;

[0082] Step 8: The controller controls the cylinder 6 to extend and drive the swing arm 5 to swing, so that the slurry box 3 can beat the wall to complete one beat and slurry throwing. At this time, the controller cylinder 6 retracts and drives the swing arm 5 to swing. At the same time, the controller controls the sliding mechanism to slide. The sliding distance is the width of the slurry box 3. Then the controller controls the cylinder 6 to extend and drive the swing arm 5 to swing so that the slurry box 3 can beat again.

[0083] Step 9: The controller controls the first sliding block of the lifting mechanism to descend the distance of one paddle box 3, and repeats step 8;

[0084] Step 10: Repeat the operation of Step 9 until the slurry is patted and splashed to the bottom of the wall. Then, the controller controls the movable walking mechanism 1 to move along the wall. The moving distance is the width of 3 slurry patting boxes 3. Repeat Step 8.

[0085] Step 11: The controller controls the first sliding block of the lifting mechanism to rise one distance of the paddle box 3, and repeats step 8;

[0086] Step 12: Repeat the operation of Step 11 until below the slapped wall imprint, then the controller controls the movable walking mechanism 1 to move along the wall, the moving distance being the width of 3 slapping boxes 3;

[0087] Step Thirteen: Repeat Steps Eight, Nine, Ten, Eleven, and Twelve to pat and roughen the lower part of the un-splashed wall surface, making the patting trajectory S-shaped.

[0088] To enhance the intelligence of the plastering device, a wall roughness sensing and recognition system can be installed. This system automatically identifies walls that have not been plastered and roughened and walls that are easy to plastered and roughened. It controls the lifting height of the first sliding block of the lifting mechanism when plastering and roughening the lower wall. It can also work with the automatic walking system of the movable walking mechanism 1 to move to the front of the wall that has not been plastered and roughened, so as to plaster and roughen the wall that has not been plastered and roughened.

[0089] The present invention also provides a method for dispensing slurry using an automated slurry dispensing device, which includes the following steps:

[0090] 1) Add slurry to the storage tank 2, move the device to the wall to be slurryed, and the feeding mechanism 7 delivers slurry to the slurry box 3;

[0091] 2) When applying mortar to a high wall surface, the cylinder 6 extends and drives the upper end of the connecting part 8 to rotate downwards, causing the mortar-applying box 3 to pat the wall surface. The second motor drives the second sliding block to move, thereby moving the support frame 4. The support frame 4 moves a distance equal to the width of the mortar-applying box 3. The cylinder 6 extends and drives the upper end of the connecting part 8 to rotate downwards again to complete the patting and mortar-applying action. After the mortar-applying box 3 completes two patting actions, the first motor drives the first sliding block to move downwards, with the first sliding block moving a distance equal to the height of the mortar-applying box 3. The cylinder 6 extends and drives the connecting part 8 to rotate, causing the mortar-applying box 3 to pat the wall surface. This process is repeated to pat the wall surface to the bottom of the upper part. The movable walking mechanism 1 moves forward along the wall surface by one mortar-applying box. The cylinder 6 extends and drives the upper end of the connecting part 8 to rotate downwards, causing the slurry-spraying box 3 to slap the wall surface. The second motor drives the second sliding block to move, thereby moving the support frame 4. The distance the support frame 4 moves is equal to the width of the slurry-spraying box 3. The cylinder 6 extends and drives the upper end of the connecting part 8 to rotate downwards again to complete the slapping and slurry-spraying action. After the slurry-spraying box 3 completes two slaps, the first motor drives the first sliding block to move upwards. The distance the first sliding block moves is equal to the height of the slurry-spraying box 3. The cylinder 6 extends and drives the connecting part 8 to rotate, causing the slurry-spraying box 3 to slap the wall surface.

Extend the cylinder 6 to drive the connecting part 8 to rotate so that the mortar-applying box 3 pats the wall. Repeat this process to mortar-apply to the bottom of the lower part of the wall. The movable walking mechanism 1 moves forward along the wall by the width of the slurry box 3. The cylinder 6 extends and drives the upper end of the connecting part 8 to rotate downward so that the slurry box 3 slaps the wall. The second motor drives the second sliding block to move so as to move the support frame 4. The support frame 4 moves a distance equal to the width of the slurry box 3. The cylinder 6 extends and drives the upper end of the connecting part 8 to rotate downward again to complete the slapping and slurry throwing action. After the slurry box 3 completes two slaps, the first motor drives the first sliding block to move upward. The moving distance of the first sliding block is equal to the height of the slurry box 3. The cylinder 6 extends and drives the connecting part 8 to rotate so that the slurry box 3 slaps the wall. This process is repeated to slap and throw slurry to the top of the lower part of the wall.
