The external fixed sleeve of the fixed rod 15 is provided with two symmetrically arranged distributing disks 16, and the distributing disks 16 are located just below the electric control valve 10. Two symmetrically arranged receiving boxes 17 are welded inside the fixed plate 2. The bottom of the fixed plate 2 is fixedly connected to a support plate 2 4 by screws, and two symmetrically arranged universal wheels 19 are installed at the bottom of the support plate 2 4. The top of the support plate 2 4 is fixedly connected to a handle 5 by screws, and a nozzle 18 is installed at the bottom of the receiving box 17. Through the arrangement of structures such as the stirring blade 9 and the distributing disk 16, starting the driving motor 7 to drive the stirring blade 9 to rotate during use can prevent the paint inside the barrel 1 from being too solidified. At the same time, the electric control valve 10 is opened and the nozzle 18 is fed through the distributing disk 16, so as to achieve the effect of avoiding blockage and uniform feeding.

[0030] like Figure 1 to Figure 5 As shown, a rotating groove is provided inside the fixed plate 2, and two material distribution plates 16 are both rotatably installed inside the rotating groove.

[0032] like Figure 1 to Figure 5 As shown, a cavity is provided inside the barrel 1, and the stirring blade 9 and the driving rod 8 are both rotatably mounted inside the cavity. A mounting groove is provided on the top of the barrel 1, and the driving rod 8 is rotatably mounted inside the mounting groove.

[0033] In this embodiment, when in use, the paint is introduced into the interior of the barrel 1 through the feed port 6 for storage. At the same time, two feed ports 6 are provided for adding and mixing different paints. When starting to spray paint, the handle 5 is held to push the entire device to move above the material, and the paint is sprayed through the nozzle 18. During this process, the drive motor 7 needs to be started, and the drive motor 7 drives the drive rod 8 to rotate. The drive rod 8 drives the stirring blade 9 to stir the paint inside the barrel 1 to avoid long-term storage and the solidification of the internal paint. At the same time, the linkage rod is driven to rotate by the synchronous belt 11, and the worm 13 on the linkage rod realizes the rotation of the fixed rod 15 by meshing with the worm gear 14. , the fixed rod 15 drives the two material distribution trays 16 to rotate. When the paint inside the barrel 1 is fully stirred, the electric control valve 10 inside the barrel 1 is started to open the two openings at the bottom of the barrel 1.

[0038] In this embodiment, the entire painting process requires that the entire device pass over the top of the material through the handle 5 and the universal wheel 19, so a cleaning disk 24 is provided at the front end of the entire device, and each part of the material will be processed by the cleaning disk 24 before being painted. The entire work process is that when the device as a whole is pushed, the driven wheel 20 starts to rotate, and when the driven wheel 20 rotates, it will drive the rotation of the worm 22, and the worm 22 drives the worm gear 23 to rotate, thereby realizing the rotation of the two cleaning disks 24. The cleaning disk 24 performs pre-treatment and cleaning work on the material at the front end, and then the spraying work is started. The pre-treatment cleaning can effectively remove larger debris or dust on the surface of the material, thereby improving the uniformity of subsequent painting and preventing paint from falling off.
