[0022] like Figure 2 、 Figure 3 As shown, the mixing box 52 is arranged above the finished product box 51, and a discharge port 56 is provided at the lower end of the mixing box 52. The discharge port 56 is horizontally slidably connected to a switch plate 57.

[0023] like Figure 2 、 Figure 3 As shown, a stirring paddle 8 is provided inside the stirring box 52 , and the stirring paddle 8 includes a pair of rotating tubes 81 , a pair of rotating rods 82 , a stirring blade 83 and a driving mechanism 9 .

[0024] like Figure 2 、 Figure 3 As shown, a pair of rotating tubes 81 are horizontally connected to the two ends of the mixing box 52, and a pair of rotating rods 82 are respectively disposed inside the pair of rotating tubes 81. The outer wall of the rotating rod 82 is provided with a spline 84, and the inner wall of the rotating tube 81 is provided with a keyway 85 for the spline 84 to slide. The mixing blade 83 is disposed on the outer wall of the rotating rod 82.

[0025] like Figure 2 、 Figure 3 As shown, the drive mechanism 9 is used to control the horizontal sliding of the pair of rotating rods 82. The drive mechanism 9 includes a drive block 91, a drive rod 92, and a cylinder 93. The drive block 91 is disposed above the position between the pair of rotating rods 82. One end of the drive rod 92 is rotatably connected to the drive block 91, and the other end is rotatably connected to the rotating rod 82. The cylinder 93 is used to control the vertical sliding of the drive block 91.

[0026] like Figure 3 、 Figure 4 As shown, the powder tank 6 is positioned above one end of the mixing tank 52 and is connected to the mixing tank 52. The powder tank 6 includes a powder hopper 61, a connecting pipe 62, a discharge pipe 63, and a rotating shaft 64. The powder hopper 61 is vertically positioned, the connecting pipe 62 is horizontally positioned below the powder hopper 61, and the discharge pipe 63 is connected between the connecting pipe 62 and the mixing tank 52. The rotating shaft 64 is horizontally connected to the connecting pipe 62 and is provided with a trough 65 for connecting the powder hopper 61 and the discharge pipe 63.

[0027] like Figure 3 、 Figure 4 As shown, a reamer 66 is horizontally rotatably connected in the powder hopper 61 , and a pulley set 67 that cooperates with each other is provided between the rotating shaft 64 and the reamer 66 .

[0028] like Figure 3 、 Figure 4 As shown, the water tank 7 is arranged above the other end of the mixing tank 52 and is connected to the mixing tank 52. The water tank 7 includes a water bucket 71, a water outlet pipe 72 and a rotary valve 73. The water bucket 71 is arranged vertically, the water outlet pipe 72 vertically connects the water bucket 71 and the mixing tank 52, and the rotary valve 73 is arranged on the water outlet pipe 72.

[0029] like Figure 3 、 Figure 4 As shown, a first ratchet 74 and a first ratchet ring 75 are provided at the end of the rotary valve 73 . The first ratchet ring 75 is rotatably connected to the outer side of the first ratchet 74 , and a first sprocket set 76 that cooperates with the rotating shaft 64 is provided between the first ratchet ring 75 and the rotating shaft 64 .

[0030] like Figure 3 、 Figure 4 As shown, a second ratchet 77 and a second ratchet ring 78 are provided at the end of the rotary valve 73. The directions of the second ratchet 77 and the second ratchet ring 78 are opposite to those of the first ratchet 74 and the first ratchet ring 75. The second ratchet ring 78 is rotatably connected to the outer side of the second ratchet 77. A motor 711 is provided on the outer wall of the water bucket 71. A second sprocket group 79 that cooperates with each other is provided between the second ratchet ring 78 and the motor 711.

[0031] When spraying is required on the wall, putty powder and clean water are added to the powder tank 6 and water tank 7, respectively. The reducer is then used to control the intermittent rotation of the rotating shaft 64. When the trough 65 on the rotating shaft 64 rotates to the upper end, the trough 65 is connected to the powder hopper 61, and the putty powder enters the trough 65. When the trough 65 rotates to the lower end, the trough 65 is connected to the discharge pipe 63, and the putty powder is quantitatively added to the mixing box 52.

[0032] When the rotating shaft 64 rotates, under the cooperation of the pulley group 67, the reamer 66 in the powder box 6 will be driven to rotate synchronously, so as to stir the putty powder, break the interaction between the putty powder, prevent the arching phenomenon, and enable the putty powder to stably enter the material trough 65.

[0033] When the rotating shaft 64 rotates, the first sprocket assembly 76 cooperates with the first ratchet ring 75 to rotate. At this time, the first ratchet ring 75 and the first ratchet wheel 74 can interact with each other, causing the first ratchet wheel 74 to rotate synchronously with the first ratchet ring 75, thereby driving the rotary valve 73 to rotate, achieving continuous opening and closing control of the water outlet pipe 72, so that clean water is quantitatively discharged into the mixing tank 52. Furthermore, when the rotating shaft 64 drives the rotary valve 73 to rotate, the second ratchet wheel 77 and the second ratchet ring 78 do not interact with each other, and will idle, thereby not affecting the motor 711.

[0034] After putty powder and clean water are put into the mixing box 52, the raw materials can be fully stirred using the stirring paddle 8. When the stirring paddle 8 is working, a pair of rotating tubes 81 rotates. At this time, under the cooperation of the spline 84 and the keyway 85, the rotating tube 81 drives the rotating rod 82 to rotate synchronously, and drives the stirring blade 83 to rotate, thereby achieving the stirring of the raw materials.

[0035] At the same time, the cylinder 93 is used to drive the driving block 91 to reciprocate vertically, the driving block 91 drives the driving rod 92 to move synchronously, and the driving rod 92 drives a pair of rotating rods 82 to move horizontally, so that the rotating rod 82 and the stirring blade 83 can move horizontally while rotating, thereby achieving sufficient stirring and mixing of the raw materials.

[0036] When the raw materials are ready, the switch panel 57 is opened, and the putty paint enters the finished product box 51 and can be sprayed out through the spray gun 3. At this time, the wall is sprayed under the action of the walking carriage 1 and the mechanical arm 2, completing the automatic spraying of the putty paint. During the putty powder spraying process, the gantry 54 is controlled by the electric cylinder 55 to move vertically. The gantry 54 drives the scraper 53 to move synchronously, scraping the paint off the inner wall of the finished product box 51, reducing paint waste.

[0037] Therefore, by setting up a batching box 5 that can prepare putty paint at all times, continuous preparation and supply of putty paint can be achieved to meet spraying needs, without stopping the machine to replenish putty paint, and at the same time, putty paint can be prepared as needed, thereby reducing putty paint waste.

[0038] When spraying operation is not required, the motor 711 is controlled to work. At this time, under the cooperation of the second sprocket group 79, the second ratchet ring 78 is driven to rotate. At this time, the second ratchet ring 78 and the second ratchet wheel 77 can rotate synchronously, and the first ratchet wheel 74 and the first ratchet ring 75 are idle.

[0039] Then the second ratchet 77 drives the rotary valve 73 to rotate, thereby opening the water tank 7, allowing clean water to pass through the positions where the paint passes in sequence, so that the clean water can rinse all working parts, ensuring the cleanliness of the working parts and avoiding blockage caused by solidification of the putty paint.

[0040] Therefore, by arranging a rotary valve 73 that can be opened and closed in both directions on the water tank 7, the water in the water tank 7 can be opened and closed following the operation of the powder box 6, thereby realizing the preparation of putty paint. It can also be opened and closed independently, so that clean water can be used to rinse all working parts, thereby ensuring the cleanliness of the working parts and avoiding the putty paint from solidifying and causing blockage.

[0041] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
