At one end of the bottom plate 1, the discharge port 15 is used to transport the material in the material barrel 2 to the outside; a discharge pipe 4 is installed at the discharge port 15, and the end of the discharge pipe 4 away from the discharge port 15 is connected and communicated with the booster pump 5, and the material barrel 2 is connected and communicated with the booster pump 5 through the discharge pipe 4 to transport the material in the material barrel 2 to the booster pump 5, and the booster pump 5 pressurizes the material transported to the inside of the booster pump 5 by the discharge pipe 4; a discharge hose 6 is connected to the output end of the booster pump 5, and the discharge hose 6 is connected and communicated with the booster pump 5, and the discharge hose 6 is away from the booster pump 5. One end is connected and communicated with a spray gun 7, and a discharge hose 6 delivers the material pressurized by the booster pump 5 to the spray gun 7, and the spray gun 7 is used to spray the material on the surface of the object to be sprayed; a nozzle 16 is connected to the end of the spray gun 7 away from the discharge hose 6, and the nozzle 16 makes the spray angle of the spray gun 7 wider and atomizes the material sprayed from the spray gun 7, so that the material passing through the nozzle 16 is more uniform during spraying; an adjustment component is installed at the bottom of the spray gun 7, and the adjustment component includes a height adjustment mechanism 8 and an angle adjustment mechanism 9, and the height adjustment mechanism 8 controls the height of the spray gun 7 Adjustment is performed so that the spray gun 7 can spray at different heights on the surface of the object to be sprayed; the angle adjustment mechanism 9 is installed on the height adjustment mechanism 8 and is used to adjust the spray angle of the spray gun 7. By changing the spray angle between the spray gun 7 and the object to be sprayed, the sprayed paint can be more evenly distributed on the surface of the object to be sprayed, reducing the omission of certain areas during the spraying process, and reducing the probability of secondary spraying or grinding due to excessive spraying of materials in certain areas due to the fixed spray angle, thereby reducing the impact of uneven spraying on the spraying efficiency.

[0028] Reference Figure 1 and Figure 2 A mounting plate 10 is connected to the bottom of the spray gun 7, and one end of the mounting plate 10 facing away from the spray gun 7 is connected to the height adjustment mechanism 8. In this embodiment, the height adjustment mechanism 8 is two telescopic rods 81 arranged in parallel, and the telescopic rods 81 are fixedly mounted on the base plate 1. The movable end of the telescopic rod 81 is fixedly connected to the base plate 1. Through the arrangement of the telescopic rod 81, when the height of the spray gun 7 needs to be adjusted, the height of the spray gun 7 can be adjusted by adjusting the movable end of the telescopic rod 81, thereby reducing the time spent on adjusting the height of the spray gun 7, and the two parallel telescopic rods 81 can improve the stability of the mounting plate 10 during the lifting process of the telescopic rod 81.

[0029] Reference Figure 1 and Figure 2 The angle adjustment mechanism 9 includes a reciprocating motor 91, a reducer 92, a rotating rod 93, a driving gear 94 and a driven gear 95. The reciprocating motor 91 and the reducer 92 are both mounted on the mounting plate 10. The output end of the reciprocating motor 91 is connected to the reducer 92, and the output end of the reducer 92 is rotatably connected to the rotating rod 93. The rotating rod 93 is rotatably mounted on the mounting plate 10, and the end of the rotating rod 93 away from the mounting plate 10 is connected to the spray gun 7. The reciprocating motor 91 enables the staff to realize the back and forth swing of the spray gun 7 within a fixed angle by setting the forward and reverse rotation of the reciprocating motor 91, thereby improving the uniformity of the spraying; the setting of the reducer 92 enables the reciprocating motor 91 to rotate back and forth. The speed of the motor 91 is adjusted to a speed suitable for the rotation of the spray gun 7 through the reducer 92, so that the material sprayed by the spray gun 7 can better adhere to the surface of the object; the driving gear 94 is fixedly connected to the output end of the reducer 92, and the driven gear 95 is fixedly sleeved on the rotating rod 93. The driving gear 94 and the driven gear 95 are meshed with each other, and the driving gear 94 is driven to rotate through the reducer 92. The driving gear 94 and the driven gear 95 are meshed with each other to drive the spray gun 7 connected to the rotating rod 93 to rotate. The driving gear 94 and the driven gear 95 are both bevel gears, and due to the characteristics of the bevel gears, the angle adjustment mechanism 9 is more stable during the rotation process.

[0030] Reference Figure 1 and Figure 2 A rotary joint 17 is installed between the discharge hose 6 and the spray gun 7. The rotary joint 17 makes the connection between the discharge hose 6 and the spray gun 7 detachable, which is convenient for repairing and replacing the spray gun 7 after long-term use.

[0031] Reference Figure 1 and Figure 3 A ball valve 18 is installed between the discharge pipe 4 and the booster pump 5. The ball valve 18 divides the discharge pipe 4 into two parts in the length direction, which are respectively connected to the material barrel 2 and the booster pump 5. At the same time, the setting of the ball valve 18 enables the connection between the material barrel 2 and the booster pump 5 to be cut off by closing the ball valve 18 when the booster pump 5 fails, thereby reducing the material waste caused by repairing the booster pump 5.

[0032] Reference Figure 1 and Figure 2 A clamping ring 11 is fixedly connected to the end of the rotating rod 93 away from the mounting plate 10. The clamping ring 11 is an arc-shaped shell with an open end. The size of the clamping ring 11 matches the size of the spray gun 7. The spray gun 7 is clamped in the clamping ring 11. When the spraying device is used for a long time and the spray gun 7 needs to be repaired and maintained, the spray gun 7 is removed from the clamping ring 11 for maintenance; the clamping ring 11 is made of elastic material, which is convenient for fixing and removing the spray gun 7.

[0033] Reference Figure 1 and Figure 3 A cleaning pipe 19 is installed at the height direction of the material barrel 2 relative to the discharge port 15. The cleaning pipe 19 is connected and communicated with the material barrel 2. A control valve is installed on the cleaning pipe 19. The control valve is used to control the communication between the cleaning pipe 19 and the material barrel 2. When the spraying work is completed, the control valve is opened, and clean water is poured from the cleaning pipe 19 into the material barrel 2 for cleaning to reduce the impact of material residue on the next spraying. After the cleaning is completed, the clean water is discharged from the cleaning pipe 19, and the control valve is closed to reduce the probability of the material in the material barrel 2 flowing out of the cleaning pipe 19 during subsequent use.

[0034] Reference Figure 1 A plurality of rollers 12 are installed at one end of the bottom plate 1 away from the material barrel 2. The rollers 12 enable the staff to change the spraying position of the spraying device by rotating the rollers 12, thereby reducing the inconvenience in the process of carrying the spraying device and making the change of the position of the spraying device quicker; in order to improve the overall stability of the spraying device after the spraying position is moved, a plurality of support columns 13 are rotatably installed on the bottom plate 1, and the support columns 13 are rotatably connected to the bottom plate 1 so that the support columns 13 can slide away from or close to the ground. When the spraying device moves to the spraying position under the sliding of the rollers 12, the support columns 13 are rotated to make them slide close to the ground, thereby improving the stability of the spraying device; on the support columns 1 A rubber pad 20 is fixedly installed at one end facing the ground. The rubber pad 20 changes the direct contact between the support column 13 and the ground into indirect contact. When the support column 13 slides toward the ground, the rubber pad 20 contacts the ground. Under the gravity of the spraying device, the rubber pad 20 is deformed, thereby increasing the contact area between the rubber pad 20 and the ground, further improving the stability of the spraying device, and reducing the impact of vibration caused by the operation of the spraying device. In order to facilitate the driving of the roller 12 to rotate, a push rod 14 is installed on the bottom plate 1 towards the material barrel 2. The push rod 14 is fixedly installed at one end in the length direction of the bottom plate 1. When the spraying device needs to be moved, applying force to the push rod 14 can make the roller 12 rotate.

[0035] In the present invention, before spraying the object to be sprayed, confirm whether the control valve is closed, whether the ball valve 18 is open, whether the spray gun 7 is blocked, whether the connection between the spray gun 7 and the discharge hose 6 is tight, whether the spray gun 7 and the nozzle 16 are installed in place, whether the booster pump 5 can work normally, whether the drive motor, the reciprocating motor 91, and the reducer 92 can work normally. After confirming that there are no problems with the above, move the spray device to the spraying position through the roller 12, slide the support column 13 toward the ground so that the spray device is in a stable working environment, pour the pre-mixed material from the feed port 3 into the material barrel 2, start the booster pump 5, so that the material moves from the material barrel 2 to the spray gun 7, and sprays through the nozzle 16, and start to The compound motor 91 and the reducer 92 make the spray gun 7 rotate through the meshing of the driving gear 94 and the driven gear 95, so that the spray gun 7 automatically changes the spray angle of the spray gun 7 during the spraying process, and realizes repeated spraying in a certain horizontal range. After reaching the preset spraying thickness, the telescopic rod 81 is started to make the spray gun 7 slide in the height direction to spray the spray object at different heights; after the spraying is completed in a certain height direction of the spray object, the support column 13 is slid away from the ground to release the support to the restriction on the sliding of the roller 12, and the spraying device is moved to the next spraying position through the push rod 14, and the support column 13 is slid toward the ground, and then spraying is carried out; repeat the above actions until the overall spraying is completed.
