[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0021] A swing-spraying airless sprayer comprises a carrier 1, an upper loading plate 11 is fixedly mounted on the upper end of the carrier 1, a lower loading plate 12 for placing a barrel is fixedly mounted on the lower end of the carrier 1, a plunger pump 6 is fixedly mounted on the upper surface of the upper loading plate 11, a feed hose 61 is mounted on the feed end of the plunger pump 6, the feed hose 61 penetrates the upper loading plate 11 and is located above the lower loading plate 12, a discharge hose 62 is mounted on the discharge end of the plunger pump 6, a spray gun 63 is fixedly mounted on the end of the discharge hose 62, a convex rotating rod 2 and a driving rod 3 are respectively penetrated and rotatably mounted on the left and right ends of the upper surface of the upper loading plate 11, and the convex rotating rod 2 and the driving rod 3 are rotatably mounted. A linkage mechanism 4 is installed between them, a sleeve 22 is slidably installed on the outer surface of the convex rotating rod 2, a tightening bolt A222 is screwed and installed between the lower end of the sleeve 22 and the convex rotating rod 2, a sleeve block 5 is fixedly installed on the top of the sleeve 22, an adapter block 52 is rotatably installed on the left surface of the sleeve block 5, a clamping hoop 53 is fixedly installed on the left surface of the adapter block 52, a spray gun 63 is clamped and fixedly installed between the clamping hoop 53 and the adapter block 52, and some damping gaskets are arranged at the adapter end between the adapter block 52 and the sleeve block 5, so that there is a certain damping effect between the two, and in actual use, the spraying angle of the spray gun 63 can be adjusted;

[0022] It should be noted that if Figure 2 As shown, the linkage mechanism 4 includes two sprockets 41 and a transmission chain 42. The two sprockets 41 are respectively mounted on the outer surfaces of the convex rotating rod 2 and the driving rod 3. The transmission chain 42 is installed between the two sprockets 41. When the driving rod 3 rotates, the convex rotating rod 2 can be driven to rotate through the linkage effect of the sprocket 41 and the transmission chain 42, so that the convex rotating rod 2 is used to drive the sleeve 22, the sleeve block 5, the adapter block 52 and the spray gun 63 to rotate, and then the spraying angle of the spray gun 63 is adjusted so that the spraying range can be expanded to the surrounding area. During the entire operation process, there is no need to adjust the position of the carrier vehicle 1. Compared with the prior art, it is convenient and labor-saving to adjust the spraying range of the spray gun 63.

[0023] When using, place the material barrel required for spraying as Figure 1 As shown, it is placed on the upper surface of the download plate 12, and then the feed hose 61 of the plunger pump 6 is placed in the material barrel. After that, after pushing the carrier 1 to the position where spraying is required, it is adjusted according to the required spraying height. When adjusting, the tightening bolt A222 is loosened, and the sliding sleeve 22 drives the spray gun 63 to adjust the height. After adjusting to the appropriate position, the tightening bolt A222 is retightened to fix the position of the sleeve 22, and then the plunger pump 6 is powered on and started. The plunger pump 6 passes the paint in the material barrel into the spray gun 63 through the feed hose 61 and the discharge hose 62 for spraying. During the spraying process, the drive rod 3 can be rotated cyclically to drive the spray gun 63 to do a swinging spraying action, so that the spraying is more uniform.

[0024] In addition, in order to improve the stability of the convex rotating rod 2 and the driving rod 3 during the rotation process, as shown in FIG. Figure 2 As shown, L-shaped support plates 111 are fixedly installed on the lower surfaces of the left and right ends of the upper carrier plate 11. After the bottom ends of the convex rotating rod 2 and the driving rod 3 are respectively embedded and rotatably installed on the upper surfaces of the corresponding L-shaped support plates 111 through bearings, the L-shaped support plates 111 can be used to limit the rotation of the bottom ends of the convex rotating rod 2 and the driving rod 3, thereby increasing the stability of the two during rotation.

[0025] In addition, when the position of the sleeve 22 is adjusted by sliding up and down, the spray gun 63 can be adjusted vertically. Figure 3 As shown, limiting grooves 21 are symmetrically provided on the outer surface of the convex rotating rod 2, and limiting ribs 221 are symmetrically fixedly installed on the inner wall of the sleeve 22. After the limiting ribs 221 are slid up and down in the corresponding limiting grooves 21, the cooperation between the limiting ribs 221 and the limiting grooves 21 can be utilized to limit the vertical adjustment of the sleeve 22 on the outer surface of the convex rotating rod 2, thereby ensuring that the spray gun 63 can be adjusted up and down, thereby reducing the spraying defects generated by the spray gun 63 during the spraying process.

[0026] Specifically, if Figure 3 As shown, a tightening bolt B51 is threadedly installed through the outer surface of the sleeve block 5, and the left end of the tightening bolt B51 is in contact with the outer surface of the sleeve 22. The sleeve block 5 is fixedly installed on the top of the outer surface of the sleeve 22 by the tightening bolt B51. When the sleeve block 5 needs to be removed, the tightening bolt B51 is loosened, and the sleeve block 5 is moved up to complete the disassembly.

[0027] like Figure 2 As shown, in order to save effort when the driving rod 3 is rotated, a hand wheel 31 is fixedly installed on the top end of the driving rod 3. The driving rod 3 can be driven to rotate by driving the hand wheel 31, making the operation more labor-saving.

[0028] Finally, in order to strengthen the load-bearing strength of the upper loading plate 11, as Figure 1 As shown, a reinforcement frame 13 is fixedly installed between the lower surface of the upper loading plate 11 and the frame of the carrier vehicle 1 , and the reinforcement frame 13 can be used to lift and support the vacant position of the left end of the upper loading plate 11 , thereby enhancing the load-bearing strength of the upper loading plate 11 .
