Description

Technical Field

[0001] This application relates to the field of plastering equipment, and more particularly to an intelligent plastering robot. Background Art

[0002] A wall plastering machine is a specialized mechanical tool used for on-site plastering and renovation of building walls, ceilings, and other surfaces. Traditional plastering work requires manual labor or tools, which is time-consuming, labor-intensive, and difficult to guarantee in terms of quality and efficiency. Wall plastering machines, on the other hand, use electric or hydraulic power to drive the plastering board or spray gun back and forth, achieving fast, precise, and safe plastering results. Therefore, wall plastering machines are widely used in building decoration work to improve construction efficiency, reduce labor intensity, and improve construction quality.

[0003] Chinese Patent CN116816042A discloses an intelligent plastering machine, including a movable plate and two guide rails mounted on the movable plate. Several casters are mounted on the bottom side of the movable plate. A coating component and a feeding component are mounted on the movable plate. The coating component includes a hopper and a drive unit that moves the hopper. One side of the hopper has a plastering opening and a plastering plate located below the opening. The feeding component includes a storage tank, a pump, and a second connecting pipe. The storage tank has an inlet for injecting slurry on its upper side. The pump is fixedly connected to one end of the storage tank and one end of the second connecting pipe, and the other end of the second connecting pipe is fixedly connected to the upper edge of the storage hopper. When feeding slurry into the storage hopper, the pump is activated to inject the slurry inside the storage tank into the storage hopper through the second connecting pipe.

[0004] However, when the storage bin is small, it can hold less slurry, requiring frequent replenishment of larger quantities of slurry, which wastes manpower. When the storage bin is large, it is difficult to move, reducing the flexibility of the plastering machine. Summary of the Invention

[0005] To save manpower and ensure the flexibility of the plastering machine, this application provides an intelligent plastering robot.

[0006] The intelligent plastering robot provided in this application adopts the following technical solution: An intelligent plastering robot includes a coating mechanism and a feeding mechanism. The feeding mechanism includes a feeding pipe connected to the coating mechanism and a storage box. The upper surface of the storage box is open. One end of the feeding pipe is a feeding port, and a feeding mechanism is installed at the feeding port. A pump body and a locking mechanism for locking the feeding pipe to the storage box are installed on the feeding pipe. The feeding mechanism includes a sealing plate located on one side of the feeding port. At least two limiting rods are fixedly connected to the sealing plate, and each limiting rod is connected to the feeding port.

[0007] By adopting the above technical solution, the intelligent plastering robot can be equipped with multiple storage bins. When the slurry in a certain storage bin is emptied, the locking mechanism connecting the supply pipe and the storage bin allows for easy unlocking and quick replacement of the storage bin, ensuring continuous robot operation. This significantly reduces the time required for the robot to stop and wait for refilling due to the depletion of slurry in a single storage bin, improving plastering efficiency, saving manpower, and maintaining the flexibility of the plastering machine. Simultaneously, the sealing plate and limiting rod in the feeding mechanism ensure the stability of the feeding port structure, allowing material to be fed directly between the sealing plate and the feeding port. This reduces the likelihood of the feeding port hitting the bottom wall of the storage bin, thus facilitating smooth material feeding.

[0008] Preferably, the outer wall of the feed inlet has multiple locking grooves arranged axially along the feed pipe. Each limiting rod is a plastic limiting rod and has a protrusion on the side wall near the feed pipe. Each protrusion engages with one of the locking grooves. The diameter of the sealing plate is larger than the diameter of the feed inlet.

[0009] By adopting the above technical solution, multiple locking grooves are formed on the outer wall of the feed inlet, arranged axially along the feed pipe. The protrusions on the side wall of the plastic limiting rod engage with the locking grooves, allowing the sealing plate to be securely installed on one side of the feed inlet. Since the diameter of the sealing plate is larger than the diameter of the feed inlet, the sealing plate can move towards the feed inlet until it blocks it. Simultaneously, the characteristics of the plastic limiting rod can be utilized to deform it, causing the sealing plate to move towards or away from the feed inlet. When the sealing plate approaches the feed inlet, the effective feeding area decreases, thus reducing the feeding rate; when the sealing plate moves away from the feed inlet, the effective feeding area increases, thereby increasing the feeding rate, achieving flexible adjustment of the feeding rate.

[0010] Preferably, a support rod is fixedly connected inside the feed inlet, a rotating shaft is rotatably connected to the support rod, and multiple blades are fixedly connected to the side wall of the rotating shaft, each blade being inclined.

[0011] By adopting the above technical solution, when the slurry flows at the inlet of the feed pipe, it impacts the inclined blades, causing the blades to drive the rotating shaft to rotate on the support rod, thereby agitating the slurry at the inlet. This agitation action ensures more uniform mixing of the slurry, guaranteeing its consistency and stability, which is beneficial for the subsequent application of the slurry by the intelligent plastering robot, improving the quality and effect of the application.

[0012] Preferably, the locking mechanism includes a connecting block installed on the feed pipe, two locking rods slidably connected to the connecting block, an installation groove is provided on one side of the storage box, the upper end of the installation groove is open, the connecting block is inserted into the installation groove, and the locking mechanism also includes a control component that drives the two locking rods to move in opposite directions and respectively abut against the side wall of the installation groove.

[0013] By adopting the above technical solution, a connecting block is installed on the feeding pipe and inserted into the mounting groove with the opening facing upward on one side of the storage box. At the same time, two sliding locking rods and a control component that drives the locking rods are provided on the connecting block. The control component can drive the two locking rods to move in opposite directions and press against the side wall of the mounting groove, thereby facilitating the locking between the feeding pipe and the storage box.

[0014] Preferably, the feed tube passes through the connecting block and is slidably connected to the connecting block. A connecting hole is provided on one side wall of the connecting block, and each locking rod is slidably connected to the connecting hole. A threaded hole communicating with the connecting hole is provided on the upper surface of the connecting block. The control component includes a threaded rod that is threadedly connected to the threaded hole. One end of the threaded rod abuts against the outer side wall of the feed tube. The threaded rod is located between two locking rods. The ends of the two locking rods that are close to each other are provided with an inclined surface that gradually slopes towards each other in the direction close to the feed tube.

[0015] By adopting the above technical solution, the feed pipe passes through the connecting block and is slidably connected to it, facilitating the adjustment of the feed pipe's position on the connecting block. A through-hole is provided in the connecting block, allowing the locking rod to slide within it and achieve telescopic movement. The threaded hole on the upper surface of the connecting block engages with the threaded rod of the control component. When the threaded rod is rotated so that one end presses against the outer wall of the feed pipe, because the threaded rod is located between the two locking rods, and the locking rods have inclined surfaces at their closest ends, as the threaded rod moves downwards, it compresses the inclined surfaces of the two locking rods, thereby driving the two locking rods to move in opposite directions and press against the side wall of the mounting groove, thus locking the feed pipe to the storage box and ensuring the stability of the feeding process.

[0016] Preferably, the two side walls of the connecting block are provided with grooves, each groove is connected to one end of the corresponding connecting hole, a spring is installed in the groove, one end of the spring is fixedly connected to the bottom wall of the groove, and the other end is fixedly connected to a corresponding locking rod.

[0017] By adopting the above technical solution, when the threaded rod needs to move away from the feed pipe and disengage from the two locking rods, since one end of the spring installed in the groove is fixedly connected to the bottom wall of the groove and the other end is fixedly connected to the corresponding locking rod, the spring will generate an elastic restoring force, pulling the locking rod to slide along the connecting hole and return to the initial position, thereby facilitating the reset of the locking rod and preparing for the next locking operation.

[0018] Preferably, an elastic plate is rotatably connected to the end of the threaded rod near the feed tube.

[0019] By adopting the above technical solution, the elastic plate can better fit the outer wall of the feed tube when the threaded rod is rotated, reducing wear and damage to the feed tube, while improving the stability of the feed tube. This also facilitates adjusting the different lengths of the feed tube entering the storage tank according to the depth of the storage tank.

[0020] Preferably, the inner diameter of the feed inlet is larger than the inner diameter of the feed pipe.

[0021] By adopting the above technical solution, the inner diameter of the feed inlet is larger than the inner diameter of the feed pipe, which makes the material enter the feed pipe more smoothly, thereby reducing the occurrence of blockage.

[0022] Preferably, the bottom surface of the storage box is equipped with multiple casters, and the upper surface of the storage box is hinged with a door for sealing the opening on the upper surface of the storage box.

[0023] By adopting the above technical solution, multiple casters are installed on the bottom of the storage box to facilitate its movement. A hinged door on the upper surface of the storage box can block the opening on the upper surface of the storage box, limiting the entry of dust and debris into the storage box.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Improved the efficiency of plastering operations, saved manpower, and ensured the flexibility of the plastering machine; 2. To achieve locking between the feed pipe and the storage box, ensuring the stability of the feeding process; 3. It facilitates the adjustment of the length of the feed pipe entering the storage bin according to the depth of the storage bin. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0031] This application discloses an intelligent plastering robot. (Refer to...) Figure 1 and Figure 2 The intelligent plastering robot includes a coating mechanism 1 and a material supply mechanism 2. The coating mechanism 1 is used to coat the slurry, and the material supply mechanism 2 is connected to the coating mechanism 1 and can transport the material to the coating mechanism 1 for wall plastering.

[0032] The feeding mechanism 2 includes a feeding pipe 21 and a storage box 22, with an opening on the upper surface of the storage box 22. One end of the feeding pipe 21 is set as a feed inlet 211 and a feeding mechanism 3 is installed at the feed inlet 211. The other end is connected to the coating mechanism 1 for feeding the coating mechanism 1.

[0033] Reference Figure 2 and Figure 3 The feeding mechanism 3 includes a sealing plate 31 located on one side of the feed inlet 211, which serves to prevent foreign objects from entering the feed pipe 21. At least two limiting rods 32 are fixedly connected to the sealing plate 31. The limiting rods 32 are generally made of plastic material, which has a certain degree of flexibility and plasticity. Multiple engagement grooves 212 arranged axially along the feed pipe 21 are formed on the outer wall of the feed inlet 211. Each limiting rod 32 has a protrusion 33 on its side wall near the feed pipe 21, and each protrusion 33 engages with one of the engagement grooves 212, thereby achieving a stable connection between the limiting rod 32 and the feed inlet 211.

[0034] The sealing plate 31 is moved toward or away from the feed inlet 211, so that the protrusions 33 on each limit rod 32 can be adjusted to engage with different locking slots 212. By selecting different locking slots 212, the relative position of the sealing plate 31 and the feed inlet 211 can be adjusted, thereby adjusting the size of the feed area of ​​the feed inlet 211.

[0035] The diameter of the sealing plate 31 is larger than the diameter of the feed inlet 211, which can better protect the feed inlet 211. That is, the sealing plate 31 is moved closer to the feed inlet 211 until the sealing plate 31 touches the feed inlet 211, thus achieving the sealing of the feed inlet 211.

[0036] Reference Figure 2 and Figure 3 To facilitate the mixing of the slurry entering the feed pipe 21, a mixing assembly 4 is installed inside the feed inlet 211. The mixing assembly 4 includes a support rod 41 fixedly connected inside the feed inlet 211. The support rod 41 is perpendicular to the axis of the feed inlet 211 and serves to support and fix subsequent components. A rotating shaft 42 is rotatably connected to the support rod 41, perpendicular to the support rod 41. Multiple blades 43 are fixedly connected to the side wall of the rotating shaft 42, each blade 43 being inclined.

[0037] When the material enters the feed pipe 21 from the inlet 211, it impacts the blades 43, causing the blades 43 to drive the rotating shaft 42 to rotate. This rotation can agitate the slurry. The blades 43 can be made of plastic or metal, as long as they have sufficient strength and corrosion resistance.

[0038] A pump body 5 is installed on the feed pipe 21. The end of the feed pipe 21 with the feeding mechanism 3 is placed into the storage box 22. Then the pump body 5 is started. At this time, the material in the storage box 22 can be transported to the coating mechanism 1 along the feed pipe 21 under the action of the pump body 5.

[0039] Reference Figure 2 and Figure 4 In order to facilitate a stable connection between the feed pipe 21 and the storage box 22, a locking mechanism 6 is connected to the feed pipe 21 to lock the feed pipe 21 and the storage box 22.

[0040] The locking mechanism 6 includes a connecting block 61 mounted on the feed pipe 21. The connecting block 61 is penetrated by the feed pipe 21 and is slidably connected to the feed pipe 21. A connecting hole 611 is provided on one side wall of the connecting block 61, through which two locking rods 62 are slidably connected. The locking mechanism 6 includes a control component that drives the two locking rods 62 to move in opposite directions and respectively abut against the side wall of the mounting groove 221.

[0041] The upper surface of the connecting block 61 has a threaded hole 612 communicating with the connecting hole 611. The control component includes a threaded rod 63 threadedly connected to the threaded hole 612. The threaded rod 63 is arranged perpendicularly to the two locking rods 62 and is located between the two locking rods 62. The ends of the two locking rods 62 that are close to each other are provided with an inclined surface that gradually slopes towards each other in the direction close to the feed pipe 21.

[0042] A mounting groove 221 is provided on one side of the storage box 22, with an opening at the upper end. The connecting block 61 is inserted into the mounting groove 221. One end of the threaded rod 63 abuts against the outer wall of the feed pipe 21. One end of each locking rod 62 with an inclined surface abuts against the thread, and the other end of each locking rod 62 abuts against the side wall of the mounting groove 221. Grooves 613 are provided on both sides of the connecting block 61. Each groove 613 communicates with one end of the corresponding connecting hole 611. A spring 64 is installed in the groove 613, and each spring 64 is sleeved on the outside of the corresponding locking rod 62. One end of the spring 64 is fixedly connected to the bottom wall of the groove 613, and the other end is fixedly connected to a corresponding locking rod 62. When the locking rod 62 abuts against the side wall of the mounting groove 221, the spring 64 is in a stretched state.

[0043] When the threaded rod 63 is rotated, it moves downwards until it presses against the feed tube 21. Simultaneously, the inclined plane pushes the two locking rods 62 in opposite directions, causing each locking rod 62 to press against the side wall of the mounting groove 221, thereby locking the feed tube 21 to the storage box 22. The spring 64 acts as a buffer and reset mechanism; when the feed tube 21 is disassembled, the spring 64 can return the locking rods 62 to their initial positions.

[0044] In addition, in order to reduce the damage to the outer wall of the feed tube 21 by the threaded rod 63, an elastic plate 65 is rotatably connected to one end of the threaded rod 63 near the feed tube 21. The elastic plate 65 can be made of rubber and has good elasticity and cushioning performance.

[0045] Reference Figure 1 and Figure 3 The inner diameter of the feed inlet 211 is larger than the inner diameter of the feed pipe 21. This design provides a buffer and gathering space for the material before it enters the feed pipe 21, which helps the material enter the feed pipe 21 more smoothly.

[0046] Each corner of the bottom surface of the storage bin 22 is equipped with casters 7, which facilitates the movement and positioning of the storage bin 22, thereby adapting to different construction sites. The upper surface of the storage bin 22 is hinged with a door 8 for sealing the opening on the upper surface of the storage bin 22. The door 8 can prevent dust, debris and other objects from entering the storage bin 22, ensuring the cleanliness of the materials.

[0047] The implementation principle of the intelligent plastering robot in this application embodiment is as follows: This intelligent plastering robot achieves efficient wall plastering operations through the cooperation of the feeding mechanism 2 and the coating mechanism 1. The design of the feeding mechanism 3 ensures the smooth and safe entry of materials into the feeding pipe 21, while the locking mechanism 6 ensures a stable connection between the feeding pipe 21 and the storage box 22, preventing loosening or displacement of the feeding pipe 21 during operation. The power provided by the pump body 5 ensures that materials can be delivered to the coating mechanism 1 in a timely manner. Compared with traditional wall plastering methods, the overall robot design greatly improves the quality and efficiency of plastering operations, reduces manual labor intensity, and overcomes problems such as uneven material feeding and inconsistent material distribution in existing technologies, bringing significant improvements and enhancements to wall plastering operations in the construction industry.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
