[0003] Common spraying equipment includes sprayers, which mainly pour putty paint into the hopper of the sprayer, and use the mechanical pump and spray gun in the sprayer to spray high-pressure putty through the nozzle of the spray gun. Due to the huge pressure difference, the putty is instantly atomized into many small particles, thereby spraying the wall. However, most existing sprayers pour the putty paint directly into the hopper after it is fully mixed. The temperature of the weather will accelerate the solidification speed of the putty in the hopper, thereby making the putty paint in the hopper unusable. Summary of the Invention

It should be noted that, unless there is a conflict, the embodiments of the present disclosure and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] See also Figures 1 to 2 , which shows a schematic structural diagram of a wall paint spraying device provided by an embodiment of the present invention. As shown in the figure, the device includes: a sprayer 1, a hopper 2 and a stirring mechanism 3.

[0020] The hopper 2 is provided on the spraying machine 1, and the discharge port of the hopper 2 (such as Figure 1 The bottom end shown in the figure is connected to the discharge pipe 11 of the sprayer 1, and is used to carry the paint used by the sprayer 1 for spraying. Specifically, the sprayer 1 can be a mobile sprayer. The hopper 2 is provided on the sprayer 1, which is connected to the discharge pipe 11 of the sprayer 1 and can carry the paint used by the sprayer 1 for spraying. Among them, the hopper 2 is also connected to a feed pipe 21 for inputting paint or water into the hopper 2, which can be threadedly connected to an external pipeline to supply additional putty material or water. In this embodiment, a support seat 22 is provided on the hopper 2 for supporting and fixing the feed pipe 21.

[0021] A stirring mechanism 3 is provided on the hopper 2 and is used to stir the paint within the hopper 2 to prevent it from solidifying. Specifically, the stirring mechanism 3 can be provided on the hopper 2 to stir the paint within the hopper 2, thereby preventing high temperatures from accelerating the solidification of the putty in the coating machine, allowing workers ample time to spray putty on indoor walls. Furthermore, when the putty material is depleted, additional putty material or water is supplied through an external pipeline threadedly connected to the interface of the feed pipe 21. During this feeding process, the rotation and stirring of the stirring mechanism 3 are not affected.

[0022] Continue to see Figures 1 to 4 The stirring mechanism 3 includes: a supporting top cover 31, a shaft 32, a plurality of stirring components 33 and a driving mechanism 34.

[0023] The support top cover 31 is used to cover the top open end of the hopper 2. Specifically, the support top cover 31 is provided with a cover hole 311 so that the shaft rod 32 can be rotatably installed in the support top cover 31 from the cover hole 311, thereby realizing the transmission connection between the driving mechanism 34 on the upper side of the support top cover 31 and the stirring assembly 33 on the lower side, and then driving the stirring assembly 33 to rotate by the driving mechanism 34, thereby realizing the stirring of the paint in the hopper 2. In the present embodiment, an assembly disk 35 can be installed on the support top cover 31 for supporting the driving mechanism 34. The assembly disk 35 can be a stainless steel frame, with a small circular plate and a large circular plate at the upper and lower ends respectively, and the large circular plate at the bottom is installed on the upper end of the support top cover 31 by bolts. The top of the support top cover 31 is provided with a cover hole 311 for the shaft rod 32 to be inserted. The assembly disk 35 can be an open structure, so the hopper 2 is not completely sealed after being covered by the top cover 31. Of course, the hopper 2 can also be a closed structure after being covered by the top cover 31, and this is not limited in this embodiment. In this embodiment, a buckle 23 can be provided between the support top cover 31 and the hopper 2 to achieve a removable fastening between the support top cover 31 and the hopper 2. The provision of the support top cover 31 can effectively reduce the exposed surface of the putty in the hopper 2.

[0024] A shaft 32 is rotatably mounted on the support cover 31 and is connected to a drive mechanism 34 for rotating the shaft 32. Specifically, the shaft 32 is vertically arranged and rotatably mounted on the support cover 31 and the mounting plate 35. The top end of the shaft 32 serves as a power input terminal and is connected to the drive mechanism 34 disposed on the mounting plate 35. This drives the stirring assembly 33 connected to the bottom end to rotate, thereby stirring the paint in the hopper 2. The drive mechanism 34 may be a servo motor.

[0025] Several stirring assemblies 33 are arranged on the shaft 32 at intervals along the circumference of the shaft 32, and are used to rotate with the shaft 32 to stir the paint. Specifically, there can be one or more stirring assemblies 33. In this embodiment, three stirring assemblies 33 are used as an example. The three stirring assemblies 33 are evenly arranged along the circumference of the shaft 32 and are connected to the shaft 32 in a detachable manner to facilitate replacement, cleaning, maintenance, etc. In this embodiment, the shaft 32 can be provided with an assembly ring 36, such as Figure 5 As shown, the assembly ring 36 is provided with a securing groove 361 corresponding to each stirring assembly 33. The stirring assembly 33 is detachably mounted in the corresponding securing groove 361. The stirring assembly 33 and the assembly ring 36 are detachably connected via a disassembly assembly 37. The assembly ring 36 is sleeved onto the upper end of the shaft 32, and the shaft 32 rotates with the stirring assembly 33 to stir the putty and prevent it from delaminating. The securing groove 361 can be a recessed structure, particularly one with an open side end, so that the stirring assembly 33 can be inserted into the securing groove 361 from the open end.

[0026] Continue to see Figure 3 , each of the stirring components 33 includes a stirring support rod 331 and a stirring rod body 332 arranged side by side and at intervals along the length direction of the stirring support rod 331. Specifically, the stirring support rod 331 can be arranged horizontally, that is, perpendicular to the shaft rod 32, and the three stirring support rods 331 are arranged in a scattered manner on the periphery of the shaft rod 32, that is, distributed in a ring shape along the center of the assembly ring 36. Among them, the stirring support rod 331 can be inserted into the corresponding fixing groove 361, and is detachably connected to the assembly ring 36 through the disassembly assembly 37. A plurality of vertically arranged stirring rod bodies 332 located below the stirring support rod 331 can be equidistantly installed on the stirring support rod 331. The vertical arrangement of the stirring rod body 332 can avoid static stratification of the putty. Among them, the stirring rod body 332 is detachably connected to the stirring support rod 331. Preferably, the stirring rod body 332 and the stirring support rod 331 can be connected by a threaded connection to achieve disassembly and assembly; for example, the lower end of the stirring support rod 331 is provided with multiple groups of threaded holes, and the stirring rod body 332 is threadedly connected to the threaded holes. In this embodiment, the lower end of each group of stirring support rods 331 is provided with three groups of threaded holes equidistantly along the length of the stirring support rod 331. Each group of threaded holes can be threadedly installed with a stirring rod body 332. The threaded installation method is convenient for later disassembly and assembly.

[0027] Continue to see Figures 5 to 7 The disassembly and assembly component 37 includes: an elastically retractable clamping component 371 and a pressing and disassembling component 372.

[0028] The assembly ring 36 is provided with an arc-shaped support groove 362 with openings at both ends, and the two open ends of the arc-shaped support groove 362 are connected to the fixing groove 361; each of the arc-shaped support grooves 362 is provided with an elastically retractable clamping piece 371, and the elastically retractable clamping piece 371 is embedded in the arc-shaped support groove 362 in a manner that can be elastically retracted, and in a free state, the two ends of the elastically retractable clamping piece 371 extend into the fixing groove 361 to be fixed to the stirring support rod 331 in the fixing groove 361 for fixing; each of the stirring support rods 331 is provided with two oppositely arranged sockets 3311, so that the end of the elastically retractable clamping piece 371 on one side of the stirring support rod 331 is inserted from the socket 3311 into the stirring support rod 331, thereby realizing the locking of the assembly ring 36 and the stirring support rod 331, and thus realizing the fixing between the two.

[0029] Specifically, if Figure 5 As shown, the arc-shaped support grooves 362 correspond one-to-one to the stirring components 33. In this embodiment, three stirring components 33 are taken as an example; three arc-shaped support grooves 362 are provided in the assembly ring 36, that is, an arc-shaped support groove 362 is provided between any two adjacent fixing grooves 361, and the two ends of the arc-shaped support grooves 362 are opened and connected to the two fixing grooves 361 on both sides, so that the two ends of the elastic telescopic fixing parts 371 arranged in the arc-shaped support grooves 362 can extend into the two fixing grooves 361 on both sides, and then the stirring mechanism 33 is locked by the ends of the two elastic telescopic fixing parts 371 on both sides of the stirring mechanism 33; wherein, the arc-shaped support grooves 362 can be a curved arc structure for placing the elastic telescopic fixing parts 371. Of course, if there is one stirring assembly 33, one fixing groove 361 and one arc-shaped supporting groove 362, both ends of which are open and communicate with the fixing groove 362, so that both ends of the arc-shaped supporting groove 362 can be inserted into the fixing groove 362, thereby locking the stirring mechanism 33 in the fixing groove 362 on both sides. In this embodiment, Figure 6 and Figure 7 As shown, one end of each stirring support rod 331 is connected to the end of the mounting ring 36 (as shown in FIG. Figure 3 The left end of the right stirring support rod 331 is shown as Figure 7 The left end shown in FIG) is provided with two oppositely arranged sockets 3311, that is, the stirring support rod 331 is connected to the left and right side plates of the end portion of the mounting ring 36 (relative to the left side plate Figure 6 As for the position shown in the figure, two relatively arranged sockets 3311 are provided, so that when the end of the stirring support rod 331 is inserted into the fixing groove 361, the ends of the elastically retractable fixing members 371 on both sides of the stirring support rod 331 can be inserted from the sockets 3311 into the stirring support rod 331, thereby locking the assembly ring 36 and the stirring support rod 331, and thus achieving the fixing between the two.

[0030] The stirring support rod 331 is hollowed out at the socket 3311, and the pressing and disassembling assembly 372 is slidably arranged on the stirring support rod 331 for sliding into the stirring support rod 331 under the action of an external force (e.g., Figure 6 As shown in the upward and downward sliding), and driving the elastic telescopic clamp 371 inserted in the stirring support rod 331 to be compressed outside the stirring support rod 331, releasing the locking between the assembly ring 36 and the stirring support rod 331 to achieve disassembly between the two.

[0031] Specifically, the stirring support rod 331 can be hollow as a whole, or it can be hollow at the end connected to the assembly ring 36, i.e., it can have a cavity. For example, the end of the stirring support rod 331 connected to the assembly ring 36 can have an assembly hole 3312 provided inside to guide the sliding of the press-to-release assembly 372. Of course, other guidance methods can also be used, which are not limited in this embodiment. The press-to-release assembly 372 is slidably disposed on the stirring support rod 331 and is partially slidably disposed within the assembly hole 3312.

[0032] In this embodiment, the elastically retractable clamping member 371 may be a compression spring. When in a free state, the two ends of the elastically retractable clamping member 371 may extend from the two open ends of the arc-shaped support groove 362 into one or two fixing grooves 361, and then be inserted into the stirring support rod 331 from the socket 3311 on the stirring support rod 331 provided in the fixing groove 361, thereby locking the stirring support rod 331 to the assembly ring 361. When the pressing and disassembly component 372 squeezes the two ends of the elastically retractable clamping member 371, the elastically retractable clamping member 371 is compressed and the two ends of the elastically retractable clamping member 371 are retracted into the arc-shaped support groove 362, disengaging from the stirring support rod 331, thereby locking the stirring support rod 331 and enabling the stirring support rod 331 to be disassembled.

[0033] Continue to see Figure 5 Both ends of the elastic telescopic clamp 371 are provided with guide balls 3711, which are used to slide and guide the telescopic deformation movement of the elastic telescopic clamp 371 in the arc groove 3612; each guide ball 3711 is provided with a limit block 3712 on the side facing away from the elastic telescopic clamp 371, which is used to be inserted from the socket 3311 to the interior of the stirring support rod 331, so as to realize the assembly between the assembly ring 36 and the stirring support rod 331.

[0034] Specifically, guide balls 3711 are provided at both ends of the elastically retractable clamping member 371 , and a limit block 3712 is installed at one end of the guide ball 3711 away from the elastically retractable clamping member 371 . The diameter of the guide ball 3711 is larger than the outer contour of the limit block 3712. The guide ball 371 can guide the elastic telescopic clamping piece 371 to be compressed and deformed into the arc groove 3612. The guide ball 371 can also limit the limit block 3712 through the guide ball 371 to prevent the limit block 3712 from being inserted into the socket 3311 and inserted as a whole into the stirring support rod 331, that is, the assembly hole 3312, that is, to ensure that when the limit block 3712 is inserted into the stirring support rod 331, ensure that the limit block 3712 can be partially placed in the socket 3311 and partially placed in the assembly hole 3312. Otherwise, when the limit block 3712 is inserted as a whole into the stirring support rod 331, that is, the assembly hole 3312, the limit block 3712 may fall directly into the assembly hole 3312, making it unable to return to the arc groove 3612. The limiting block 3712 may be provided with a compression guide surface, which can guide the limiting block 3712 to move toward the outside of the stirring support rod 331 under the extrusion action of the pressing and disassembling member 372 .

[0035] Continuing the case Figure 6 and Figure 7 The pressing and disassembling member 372 includes: an extrusion block 3721 , a movable block 3722 and an elastic force applying member 3723 .

[0036] The extrusion block 3721 is slidably disposed inside the stirring support rod 331, and one end of the extrusion block 3721 (such as Figure 6 The top of the stirring support rod 331 is provided with a movable block 3722, which can be slidably passed through the support plate (as shown in FIG. Figure 6 The top plate shown in the figure) is used to partially protrude from the outside of the stirring support rod 331, and is used to drive the extrusion block to slide toward the socket 3311 under the action of external force, so as to squeeze the elastic telescopic clamping piece 371 inserted in the stirring support rod 331, so that it is compressed toward the outside of the stirring support rod 331.

[0037] Specifically, the extrusion block 3721 is movably arranged in the internal cavity of the stirring support rod 331, and a movable block 3722 is installed on the upper end of the extrusion block 3721. The movable block 3722 and the top plate of the stirring support rod 331 are movably interlaced, wherein the extrusion block 3721 and the movable block 3722 can be fixedly connected, and the movable block 3722 is smaller than the size of the extrusion block 3721, and can be slid upwardly and limited by the extrusion block 3721. The movable block 3722 is slidably arranged in the top plate of the stirring support rod 331 in the vertical direction, and the extrusion block 3721 is slidably arranged in the assembly hole 3312 in the vertical direction. The sliding of the extrusion block 3721 and the movable block 3722 can be guided by the hole position of the top plate, and the sliding of the extrusion block 3721 and the movable block 3722 can also be guided by the assembly hole 3312. Among them, the end of the extrusion block 3721 facing away from the movable block 3722 (such as Figure 6 The bottom end of the stirring support rod 331 is provided with an extrusion guide surface 37211 to squeeze the limit block 3712 from the socket 3311 to the outside of the stirring support rod 331.

[0038] The elastic force member 3723 is provided between the inner wall of the stirring support rod 331 and the extrusion block 3721, and is used to apply an elastic force to the extrusion block 3721 so that the extrusion block 3721 moves away from the socket 3311 and is limited to a position where it contacts the inner wall of the support plate (such as Figure 6 The top wall shown in the figure) is provided to make way for the elastic retractable clamping piece 371 inserted at the socket 3311, and can be elastically compressed when the extrusion block 3721 slides toward the socket 3311, so that the extrusion block 3721 and the movable block 3722 can be reset under the elastic force of the elastic force-applying piece 3723 when in a free state.

[0039] Specifically, the elastic force-applying member 3723 is disposed between the lower end of the extrusion block 3721 and the bottom wall of the stirring support rod 331. The elastic force-applying member 3723 can be in a compressed state to apply an upward force to the extrusion block 3721, so that the extrusion block 3721 and the movable block 3722 can move upward to a yielding position when in a free state, i.e., when no external force is applied. In other words, the top wall of the extrusion block 3721 presses against the bottom wall of the top plate of the stirring support rod 331. The extrusion block 3721 can yield to the socket 3311, allowing the limit block 3712 to extend from the socket 3311 into the interior of the stirring support rod 331. Under the action of external pressure, the movable block 3722 drives the extrusion block 3721 downward, and can squeeze the limit block 3712 by squeezing the guide surface 37211, so that it moves from the socket 3311 toward the outside of the stirring support rod 331.

[0040] In this embodiment, the elastic force-applying member 3723 can be a compression spring, which can always be in a compressed state, especially when the yielding extrusion block 3721 and the movable block 3722 are in the yielding position. It is also in a compressed state, ensuring the stability of the extrusion block 3721 and the movable block 3722 in the yielding position in a free state, preventing the extrusion block 3721 and the movable block 3722 from squeezing the limit block 3712 by themselves, and thereby preventing the assembly ring 36 from falling off by itself from the stirring support rod 331.

[0041] In this embodiment, when the stirring support rod 331 is installed in the fixing groove 361, the sockets 3311 opened on both sides of the stirring support rod 331 are in a coaxial position with the limit blocks 3712 on the outside of the guide ball 3711, and the limit blocks 3712 will be inserted into the inside of the socket 3311 to form a plug-in fixation. When the stirring support rod 331 needs to be disassembled later, the movable block 3722 is manually squeezed, and the squeezing block 3721 squeezes out the limit blocks 3712 plugged into the sockets 3311 on both sides. At this time, the stirring support rod 331 can be pulled out.

[0042] In this embodiment, the support seat 22 and the feed pipe 21 can be installed on the support top cover 31, and both the support seat 22 and the feed pipe 21 can be provided with two groups, and are symmetrically distributed at the upper end of the support top cover 31. Later, the external pipeline can be connected to the interface thread of the feed pipe 22 to supply additional putty material or water.

[0043] The method of using the wall paint spraying device is as follows: when in use, connect a hose and a spray gun to the discharge port below the sprayer 1, remove the support top cover 31 from the upper end of the hopper 2, and pour putty material into the interior of the hopper 2, manually install the support top cover 31 from top to bottom on the upper end of the hopper 2, and the assembly ring 36 and the stirring support rod 331 installed on the shaft 32 stir the putty inside the hopper 2 after being driven by the driving mechanism 34 to avoid the high temperature of the weather causing the putty to solidify faster. At this time, the staff can have enough time to spray putty on the indoor walls. When the putty material is exhausted, the putty material or water is supplied through the external pipeline and the interface threaded connection of the feed pipe 21. During the feeding process, it will not be affected by the rotation and stirring of the stirring support rod 331.

[0044] In summary, the wall paint spraying device provided in this embodiment stirs the paint in the hopper 2 through the stirring mechanism 3 provided on the hopper 2, which can prevent the putty from being stratified while standing and can also delay the solidification of the putty. The staff can use the sprayer to spray putty on the wall, and can avoid the high weather temperature causing the putty of the paint machine to solidify faster. At this time, the staff can have sufficient time to spray putty on the indoor walls, which solves the problem that the putty in the hopper of the existing sprayer is affected by the weather temperature and solidifies, making the putty paint in the hopper unusable.

[0045] Furthermore, the disassembly component 37 facilitates the installation of the stirring support rod 331 by cooperating with the elastic retractable clamping piece 371, the guide ball 3711 and the limit block 3712 in the fixing groove 361 opened in the assembly ring 36. During the later disassembly, it is only necessary to manually squeeze the movable block 3722 to separate the stirring support rod 331 from the assembly ring 36. The disassembly and assembly method is convenient, and it is easy to disassemble and clean separately afterwards, avoiding the solidified putty remaining on its surface, and preventing the solidified putty from mixing with the subsequent new putty to cause color difference.
