[0053] By arranging the spiral scraper 3, when some paint stored for a long time or having a large viscosity is sprayed, the original bucket cover of the paint bucket is first opened, then the mounting cover 2 is buckled on the top of the paint bucket from top to bottom, in the process of moving the mounting cover 2 from top to bottom, the spiral scraper 3 can be inserted into the paint bucket and kept in close contact with the inner wall of the side of the paint bucket, after the mounting cover 2 is completely buckled on the top of the paint bucket, the two second adjusting screw rods 20 are successively screwed, so that the two arc-shaped clamping plates 19 can be respectively pressed tightly together with the two sides of the paint bucket under the driving of the two second adjusting screw rods 20, when the arc-shaped clamping plate 19 is in contact with the paint bucket, the magnetic piece 21 can be attracted to the paint bucket, so as to cooperate with the clamping action of the two arc-shaped clamping plates 19 and the paint bucket, so that the mounting cover 2 is fixed on the top of the paint bucket, then the depth of the suction pipe 15 inserted into the paint bucket is adjusted according to the depth of the paint bucket, after the position of the suction pipe 15 is adjusted, the first adjusting screw rod 17 is tightened, so that the suction pipe 15 is locked in the current position under the pressing action of the first adjusting screw rod 17.

[0054] When using the spraying machine body 1, connect the spray gun to the connector 26, and then start the drive assembly. At this time, the drive assembly can drive multiple spiral scrapers 3 to stir and mix the paint in the paint bucket, so that the paint that has been stored for a long time can be gradually stirred evenly. After the spiral scrapers 3 have stirred the paint for a period of time, start the spraying machine body 1 to perform the spraying operation. At this time, the paint can be evenly sprayed onto the wall or ceiling. At the same time, as the spiral scrapers 3 scrape against the inner side of the paint bucket, the spiral scrapers 3 can drop the paint adhering to the inner side of the paint bucket from the inner side of the paint bucket into the paint at the bottom of the paint bucket, thereby avoiding the waste of the paint adhering to the inner side of the paint bucket.

[0055] In addition, when spraying paints with low viscosity and short shelf life, the first adjusting screw 17 can be loosened, and then the suction tube 15 can be removed from the sleeve 16 and directly inserted into the paint bucket for use, which improves the convenience of use.

[0056] like Figures 1 to 8 As shown, the drive assembly includes: a drive ring 4, a drive component 5, a gear 6, and a clamping mechanism. The drive ring 4 is rotatably connected to the bottom of the mounting cover 2, and the drive ring 4 and the mounting cover 2 are coaxial. The inner side of the drive ring 4 is evenly provided with teeth. The drive component 5 can be a motor, which is fixedly installed on the top of the mounting cover 2 to provide power to the drive ring 4. The output shaft of the drive component 5 is vertically rotatably inserted into the mounting cover 2. The gear 6 is connected to the output shaft at the bottom of the drive component 5, and the gear 6 meshes with the teeth on the inner side of the drive ring 4. There are multiple clamping mechanisms, which are evenly distributed in a ring at the bottom of the drive ring 4 to press the spiral scraper 3 against the inner wall of the paint bucket side.

[0057] The clamping mechanism includes: a fixed strip 7, a movable strip 8, a slider 9, an elastic element 10, and an adjusting element. The fixed strip 7 is connected to the bottom of the drive ring 4 and is located on the diameter of the drive ring 4. The bottom of the fixed strip 7 has a mounting groove, and both sides of the mounting groove facing the axis of the drive ring 4 are open. The movable strip 8 is slidably installed in the mounting groove at the bottom of the fixed strip 7, and the bottom of the movable strip 8 has a sliding groove, with the side of the sliding groove away from the axis of the drive ring 4 being open. The slider 9 is slidably installed in the sliding groove at the bottom of the movable strip 8, and the slider 9 is fixedly connected to the spiral scraper 3. The elastic element 10 can be a spring, and both ends of the elastic element 10 are fixedly connected to the inner wall of the movable strip 8 and the sliding groove near the axis of the drive ring 4, respectively. The elastic element 10 is used to press the spiral scraper 3 tightly against the inner wall of the paint bucket. The adjusting element is connected to the fixed strip 7 and is used to adjust the distance between the spiral scraper 3 and the inner wall of the paint bucket according to the different inner diameters of the paint bucket.

[0058] Due to the difference of the diameter of the paint bucket, when aiming at the paint bucket with different diameters, the distance between the spiral scraper 3 and the suction pipe 15 can be adjusted through the adjusting piece first, so that the distance between the side of the spiral scraper 3 close to the inner wall of the paint bucket and the suction pipe 15 is slightly larger than the radius of the paint bucket, when the spiral scraper 3 is adjusted, the cover 2 is buckled from top to bottom on the top of the paint bucket, in this process, the sliding block 9 can be pressed towards the suction pipe 15, so that the sliding block 9 can extrude the corresponding elastic piece 10, and at the same time, the spiral scraper 3 can be moved towards the suction pipe 15 under the drive of the sliding block 9, so that the spiral scraper 3 can be smoothly put into the paint bucket, when the spiral scraper 3 is about to be inserted into the paint bucket, the sliding block 9 is released, at this time, the sliding block 9 can drive the spiral scraper 3 to be close to the inner wall of the side of the paint bucket under the push of the elastic piece 10, after the cover 2 is completely covered on the top of the paint bucket, the cover 2 and the paint bucket are fixedly connected together through the two fixing assemblies, then the driving piece 5 is started, at this time, the driving piece 5 can drive the driving ring 4 to rotate through the gear 6, and with the rotation of the driving ring 4, the spiral scraper 3 can be stirred under the drive of the driving ring 4 at the same time, the spiral scraper 3 can also be scraped along the inner wall of the side of the paint bucket, so that the paint attached to the inner wall of the side of the paint bucket can fall from the inner wall of the side of the paint bucket to the paint at the bottom of the paint bucket under the scraping of the spiral scraper 3, thereby avoiding the waste of the paint attached to the inner wall of the side of the paint bucket.

[0059] As shown in Figures 4 to 7 The adjusting piece comprises: an installation ring 11, an adjusting disc 12, a lever 13 and a locking piece, the installation ring 11 is fixedly connected to the top of the plurality of fixing strips 7; the adjusting disc 12 is rotationally installed on the installation ring 11; the lever 13 is connected to the top of the movable strip 8, the top of the fixing strip 7 and the lever 13 are provided with a strip-shaped notch at the corresponding position, and the notch is located on the same movement track as the lever 13, so that the fixing strip 7 cannot block the movement of the lever 13, the adjusting disc 12 is provided with a guide hole at the position opposite to the lever 13, the guide hole is inclined, and the lever 13 is inserted into the guide hole; the locking piece is connected between the adjusting disc 12 and the driving ring 4, for locking the position of the adjusting disc 12 after rotation;

[0060] The locking member comprises an arc-shaped plate 22, an arc-shaped pressing strip 23 and a third adjusting screw 24. The arc-shaped plate 22 is fixedly connected to the bottom of the driving ring 4, and the axis of the arc-shaped plate 22 coincides with the axis of the driving ring 4. A limiting hole is horizontally and through formed in the arc-shaped plate 22. The arc-shaped pressing strip 23 is horizontally and slidably arranged on the side of the arc-shaped plate 22 away from the adjusting disc 12, and the arc-shaped pressing strip 23 can move a distance along the diameter direction of the driving ring 4, so as to realize the close or separation operation of the arc-shaped pressing strip 23 and the arc-shaped plate 22. The third adjusting screw 24 is horizontally and through inserted into the limiting hole and is threadedly connected to the arc-shaped pressing strip 23. The third adjusting screw 24 is connected to the bottom of the adjusting disc 12 through a fixing block, and the third adjusting screw 24 is rotationally connected to the fixing block.

[0061] Since the diameters of the paint buckets are different, when the paint buckets with different diameters are targeted, the third adjusting screw 24 can be loosened first, so that the arc-shaped pressing strip 23 can move away from the arc-shaped plate 22 under the action of the third adjusting screw 24, and then the arc-shaped pressing strip 23 can be slightly separated from the arc-shaped plate 22, so that the locking effect of the arc-shaped pressing strip 23 on the arc-shaped plate 22 is released. Then, the adjusting disc 12 is rotated, so that the adjusting disc 12 can push the push rod 13 to move through the obliquely arranged guide hole. With the movement of the push rod 13, the movable strip 8 can drive the spiral scraper 3 to move along the diameter direction of the driving ring 4 under the action of the push rod 13, so as to change the distance between the spiral scraper 3 and the suction pipe 15, and then meet the scraping requirements of the spiral scraper 3 on the inner wall of the paint bucket with different diameters. When the position of the spiral scraper 3 is adjusted, the distance between the side of the spiral scraper 3 close to the inner wall of the paint bucket and the suction pipe 15 is slightly greater than the radius of the paint bucket, so that when the spiral scraper 3 is put into the paint bucket, the spiral scraper 3 can be close to the inner wall of the paint bucket under the pushing force of the elastic member 10 on the sliding block 9, and then the scraping effect of the spiral scraper 3 on the paint on the inner wall of the paint bucket is ensured.

[0062] When the position of the spiral scraper 3 is adjusted, the third adjusting screw 24 can be tightened, so that the arc-shaped pressing strip 23 can be pressed tightly with the arc-shaped plate 22 under the pulling of the third adjusting screw 24, so as to realize the locking of the position of the adjusting disc 12 after rotation through the friction between the arc-shaped pressing strip 23 and the arc-shaped plate 22.

[0063] As shown in Figures 4 to 8 The number of the pressing mechanism and the spiral scraper 3 is multiple, and they are one-to-one corresponding. The side of the spiral scraper 3 close to the suction pipe 15 is uniformly and fixedly connected with a plurality of horizontally arranged stirring rods 18.

[0064] Through the arrangement of the stirring rod 18, the stirring rod 18 can stir the paint close to the middle position of the paint bucket during the process that the spiral scraper 3 scrapes the paint on the inner wall of the paint bucket and stirs the paint in the paint bucket, thereby improving the stirring efficiency of the paint together with the spiral scraper 3.

[0065] As shown in Figure 9 The roller 25 is installed on the side of the sliding block 9 away from the suction pipe 15, which is used to reduce the friction between the sliding block 9 and the inner wall of the paint bucket.

[0066] When the sliding block 9 is attached to the inner wall of the paint bucket under the pushing of the elastic member 10, the sliding block 9 can move around the suction pipe 15 under the driving of the driving ring 4 as the driving member 5 drives the driving ring 4 to rotate through the gear 6. In this process, the sliding block 9 can drive the spiral scraper 3 to scrape along the side wall of the paint bucket under the action of the elastic member 10, and the roller 25 can roll along the inner wall of the paint bucket, thereby reducing the friction between the sliding block 9 and the inner wall of the paint bucket, so that the sliding block 9 can drive the spiral scraper 3 to move more smoothly.

[0067] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it.
