[0030] Example 1:

[0031] See also Figure 1 、 Figure 2 As shown, a spraying device with an adjustable spraying range provided in an embodiment of the present application includes a feed pipe 1; a fixed plate 5, the fixed plate 5 includes a first fixed plate 51 and a second fixed plate 52, the first fixed plate 51 and the second fixed plate 52 are respectively installed in parallel on the upper and lower sides of the outer wall of the discharge port of the feed pipe 1, and the first fixed plate 51 is provided with a through hole 53 passing through the upper and lower parts; a first nozzle assembly, the first nozzle assembly includes a first mounting block 7 and a first nozzle 71; the front end of the first mounting block 7 is connected to the first nozzle 71, and the rear end is connected to the feed pipe 1; the upper end of the first mounting block 7 is slidably connected in the through hole 53, and the lower end is connected to the second fixed plate 52.

[0032] In this embodiment, through-hole 53 is arcuate, and feed pipe 1 is used to supply material. A space for accommodating the first nozzle assembly is formed between first fixing plate 51 and second fixing plate 52. The through-hole in first fixing plate 51 engages with the upper end of first mounting block 7, allowing first mounting block 7 to slide on first fixing plate 51. First nozzle 71 is fixed to first mounting block 7 and moves with first mounting block 7. During operation of the device, material is sprayed from first nozzle 71 through the feed pipe. To change the spraying range, the upper end of first mounting block 7 is slid within through-hole 53 to change the position of first nozzle 71, thereby changing the spraying range.

[0033] See also Figure 1 、 Figure 2 、 Figure 3 As shown, a plurality of circular limiting grooves 54 are provided on the upper end surface of the second fixing plate 52, and correspond to the positions of the arc-shaped through holes 53; a grip rod 72 is provided on the top of the first mounting block 7, and the grip rod 72 is slidably connected in the through hole 53. An elastic member 73 is provided inside the first mounting block 7, and the two ends of the elastic member 73 are respectively connected to the upper inner wall of the first mounting block 7 and the first end of the insertion rod 74, and the second end of the insertion rod 74 extends out from the bottom of the first mounting block 7 and engages with the limiting groove 54, and the second end of the insertion rod 74 is hemispherical.

[0034] When the upper part of the gripping rod 72 is pushed, the first mounting block 7 is driven to move along the arc-shaped through hole 53. Since an elastic member 73 is provided inside the first mounting block 7, and the elastic member 73 is connected to the first end of the insertion rod 74, the second end of the insertion rod 74 is squeezed by the upper end surface of the second fixing plate 52 during the movement, causing the elastic member 73 to contract. When it moves into the circular limiting groove 54, the insertion rod 74 extends out under the action of the rebound force of the elastic member 73, thereby achieving a snap connection with the circular limiting groove 54. The second end of the insertion rod 74 can stay on the circular limiting groove 54 at different positions, so that the first nozzle 71 stays at the required angle.

[0035] See also Figure 3 As shown, a slider 75 is connected between the elastic member 73 and the insertion rod 74, and the slider 75 slides up and down inside the first mounting block 7. The edge of the slider 75 abuts the lower inner wall of the first mounting block 7, and the insertion rod 74 is connected to the middle part of the lower end surface of the slider 75. The slider 75 serves as a force transmission structure between the elastic member 73 and the insertion rod 74, ensuring that the elastic member 73 is subjected to more uniform force, avoiding damage to the elastic member 73, and ensuring that the insertion rod moves up and down more smoothly.

[0036] See also Figure 1 、 Figure 2 As shown, the second nozzle assembly is also included, which includes a second mounting block 6 and a second nozzle 61. The second mounting block 6 is mounted between the first fixing plate 51 and the second fixing plate 52. The front end of the second mounting block 6 is connected to the second nozzle 61, and the rear end of the second mounting block 6 is connected to the feed pipe 1. The second mounting block 6 is fixed between the first fixing plate 51 and the second fixing plate 52 to fix the angle of the second nozzle 61, which facilitates quick use when spraying a small area.

[0037] See also Figure 1 、 Figure 2 As shown, the feed pipe 1 is connected to the first mounting block 7 through the first connecting pipe 41, and the feed pipe 1 is connected to the second mounting block 6 through the second connecting pipe 42. Valves 43 are provided on the first connecting pipe 41 and the second connecting pipe 42. Protective shells 44 are provided on the outside of the first connecting pipe 41 and the second connecting pipe 42. The valves 43 pass through the protective shells 44 and are connected to the first connecting pipe 41 and the second connecting pipe 42 respectively. The opening and closing of the first connecting pipe 41 and the second connecting pipe 42 are controlled by the valve 43. The opening and closing of each nozzle or the material flow rate is adjusted by adjusting the valve. The protective shell 44 is provided to install and protect the internal pipeline.

[0038] See also Figure 2 As shown, it also includes a dividing block 3, and the first connecting pipe 41 and the second connecting pipe 42 are both connected to the feeding pipe 1 through the dividing block 3. After the dividing block 3 quantitatively distributes the material, the material enters the first connecting pipe 41 and the second connecting pipe 42.

[0039] See also Figure 1 、 Figure 2 As shown, it also includes: a sleeve 2, which wraps the middle parts of the first connecting pipe 41 and the second connecting pipe 42, and the sleeve 2 protects the first connecting pipe 41 and the second connecting pipe 42.

[0040] See also Figure 1 、 Figure 2 As shown, there are two groups of first nozzle assemblies, which are respectively arranged on both sides of the second nozzle assembly. By arranging multiple groups of first nozzle assemblies, the spraying range is wide and the flexibility is high.

[0041] Furthermore, the elastic member 73 is a spring.

[0042] The use process of the spraying device of this embodiment is as follows:

[0043] When in use, first install the feed pipe 1 on the spray gun or other paint delivery equipment, then adjust the position of the first mounting block 7 as needed, operate the handle 72 to drive the first mounting block 7 to move along the arc-shaped through hole 53, and when it moves into the circular limit groove 54, the insertion rod 74 extends from the first mounting block, thereby achieving a snap connection with the circular limit groove 54, and the second end of the insertion rod 74 can stay on the circular limit groove 54 at different positions, so that the first nozzle 71 stays at the required position, open the valve 43 on the corresponding connecting pipe, and start spraying, realizing multi-angle and large-scale spraying.
