[0002] Wall paint is used to decorate and protect building walls, making them beautiful and neat. It can also protect building walls and extend their service life. Wall paint is classified into two parts: interior wall paint and exterior wall paint. Interior wall paint focuses on decoration and environmental protection, while exterior wall paint focuses on protection and durability. When spraying, the spray gun is aimed at the wall to spray a cone-shaped spray to spray the wall. The stirring devices of existing wall spraying equipment are all handheld, which is laborious, and the stirring is not uniform enough, which puts a heavy load on the workers' arms. Summary of the invention

The paint is stirred by the first stirring rod and the second stirring rod and then enters the second cylinder again through the second opening for circulation, so that the paint can be continuously stirred, the stirring is more uniform and no manual intervention is required, thereby reducing the labor intensity of manual labor.

When the paint enters the first cylinder, the auger fixed on the inside of the first cylinder drives the paint to move downward, and enters the gap between the first cylinder and the second cylinder through the first opening. A plurality of first stirring rods arranged on the inside of the first cylinder and a plurality of second stirring rods arranged on the outside of the second cylinder stir the passing paint. The paint then enters the second cylinder through the second opening and is transported downward by the auger again, thereby realizing continuous circulation and stirring of the paint, so that the paint is stirred more thoroughly.

[0005] Furthermore, the power mechanism includes a motor and a first rotating rod provided on the bottom plate, the output shaft of the motor is connected to the lower end of the first rotating rod, a first gear is fixed on the first rotating rod, and a first gear ring meshing with the first gear is fixed on the outer side of the first cylinder.

[0008] Furthermore, the second opening is located on the upper side of the auger, and the lower end of the first opening is opened to the upper surface of the bottom plate, so as to prevent part of the paint from being left in the second cylinder during transportation and unable to be stirred and transported out.

[0009] Furthermore, the upper end of the second cylinder is connected to a material inlet pipe, and the outer side of the first cylinder is connected to a material outlet pipe, and the material outlet pipe is arranged on the bottom plate.

[0010] Through the above technical solution, the beneficial effects of the utility model are:

When the paint enters the first cylinder, the auger fixed on the inner side of the first cylinder drives the paint to move downward, enters the gap between the first cylinder and the second cylinder through the first opening, and then moves upward. The multiple first stirring rods arranged on the inner side of the first cylinder and the multiple second stirring rods arranged on the outer side of the second cylinder stir the passing paint, and the paint then enters the second cylinder through the second opening and is transported to the bottom again by the auger, thereby realizing continuous circulation and stirring of the paint, so that the paint is stirred more thoroughly, and no manual participation is required, thereby reducing the labor intensity of manual labor.

[0021] In this embodiment, Figure 4 As shown, the first barrel 2 and the second barrel 3 are cylindrical barrels with closed upper ends and the centers of the two coincide. The upper end of the second barrel 3 extends out of the first barrel 2 and is rotatably connected to the first barrel 2. The first opening 5 and the second opening 6 are both arc-shaped openings. The first stirring rod 7 is circumferentially arranged on the inner side of the first barrel 2 and arranged in multiple layers up and down. The second stirring rod 8 is circumferentially arranged on the outer side of the second barrel 3 and arranged in multiple layers up and down. The multiple layers of the first stirring rod 7 and the second stirring rod 8 are staggered up and down to avoid position interference, and as the first barrel 2 and the second barrel 3 rotate, the paint can be stirred more fully.

[0022] The power mechanism drives the first cylinder 2 and the second cylinder 3 to rotate as follows: the power mechanism includes a motor 21 and a first rotating rod 22 arranged on the base plate 1, the output shaft of the motor 21 is connected to the lower end of the first rotating rod 22, a first gear 23 is fixed to the first rotating rod 22, a first gear ring 24 meshing with the first gear 23 is fixed to the outer side of the first cylinder 2, the power mechanism also includes a second rotating rod 31 rotatably connected to the base plate 1, a second gear 32 is also fixed to the first rotating rod 22, the second gear 32 is located above the first gear 23, a third gear 33 meshing with the second gear 32 is fixed to the second rotating rod 31, and the second cylinder 3 extending out of the first cylinder 2 is fixed with a second gear ring 34 meshing with the third gear 33.

[0023] The motor 21 drives the first gear 23 and the second gear 32 on the first rotating rod 22 to rotate, and the first gear ring 24 meshing with the first gear 23 drives the first cylinder 2 to rotate. The third gear 32 fixed on the second rotating rod 31 rotatably connected to the bottom plate 1 is meshed with the second gear on one side and the second gear ring 24 on the other side, thereby driving the second cylinder 3 to rotate. At this time, the rotation directions of the first cylinder 2 and the second cylinder 3 are opposite.

[0024] Specifically, the second opening 6 is located on the upper side of the auger 4, and the lower end of the first opening 5 is opened to the upper surface of the bottom plate 1. The second opening 6 is located on the upper side of the auger 4, which can prevent the paint from directly entering the gap between the first cylinder 2 and the second cylinder 3 through the second opening 6, thereby affecting the stirring efficiency of the paint. The lower end of the first opening 5 is opened to the upper surface of the bottom plate 1, so that there is no plate blocking between the first opening 5 and the bottom plate 1, which can prevent part of the paint from being blocked in the first cylinder 2, causing uneven stirring of the paint.

[0025] In this embodiment, if Figure 1 As shown, the upper end of the second cylinder 3 is connected to a feed pipe 61, and the outer side of the first cylinder 2 is connected to a discharge pipe 62, which is arranged on the bottom plate 1.

The fixing rod 41 rotates as the second cylinder 3 rotates.

[0027] When in use, the paint enters the second cylinder 3 from the feed pipe 61, and the motor 21 is turned on at this time. The motor 21 drives the first gear 23 and the second gear 32 on the first rotating rod 22 to rotate, and the first gear ring 24 meshing with the first gear 23 drives the first cylinder 2 to rotate. The third gear 32 fixed on the second rotating rod 31 rotatably connected to the bottom plate 1 is meshed with the second gear on one side and the second gear ring 24 on the other side, thereby driving the second cylinder 3 to rotate. At this time, the rotation directions of the first cylinder 2 and the second cylinder 3 are opposite, and the auger 4 inside the second cylinder 3 drives the paint to move downward When the paint moves downward, it passes through the first outlet 5 and enters the gap between the first cylinder 2 and the second cylinder 3, and then moves upward. The first stirring rod 7 arranged on the inner side of the first cylinder 2 and the multiple second stirring rods 8 on the outer side of the second cylinder 3 stir the passing paint. In this process, the rotation directions of the first stirring rod 7 and the second stirring rod 8 are opposite. The paint will continue to move upward, and then enter the second cylinder 3 through the second opening 6, and be driven downward by the auger 4 again, so as to realize the circulating stirring of the paint. After the stirring of the paint is completed, it can be transported out through the discharge pipe 62.
