[0035] In an optional implementation manner of the embodiment of the present invention, as Figure 1 As shown, a group of horizontal sliders 18 are installed on the slide rail I 21, and two groups of horizontal sliders 18 are installed on the slide rail II 31. The mechanisms installed on the horizontal sliders 18 are the same.

[0036] Working principle: When the present invention is in use, the width of the spraying can be adjusted at any time according to the actual needs during spraying, and the spraying angle can be adjusted during spraying, so that the nozzle 1 forms a certain angle with the bottom surface, so that the nozzle 1 can better adapt to surfaces of different shapes, especially when the surface is uneven or rapid painting is required in a short time, the oblique spraying can better cover and spray, and the liquid spraying direction of the oblique nozzle reduces the paint splashing phenomenon and reduces the environmental pollution during spraying; when the present device is in use, a plurality of groups of nozzles 1 are provided, which can spray one mark or two marks, and when spraying two marks, the distance between the two marks can also be adjusted, thereby improving the adaptability of the spraying and facilitating the drone to measure and shoot the land boundaries.

[0037] When the device is in use, first place the storage tank 14 filled with paint on the bottom frame 15, then insert the lower end of the connector 10 obliquely into the cylinder at the upper end of the spray head 1, and bend the upper end inward, so that the upper end of the connector 10 contacts the inclined surface of the lower end of the top block 12, thereby pressing the top block 12 upward, and compressing the compression spring 11. When the upper end of the connector 10 is completely inserted into the groove at the lower end of the top block 12, the top block 12 moves downward under the action of the compression spring 11, and the connector 10 is clamped. Then the plunger pump in the storage tank 14 squeezes the paint into the connector 10, thereby squeezing the paint from the lower end of the connector 10 into the spray head 1, and spraying it out from the outlet at the bottom of the spray head 1; Before spraying, the width of the spraying can also be set. Specifically, the motor I5 is started to drive the screw rod I4 to rotate, thereby driving the slide plate 3 to slide left and right. When the slide plate 3 slides inward, the bottom of the slide plate 3 will squeeze the short rod 9, thereby driving the baffle 6 to slide downward, so that the lower end of the baffle 6 blocks the spraying port below the nozzle 1. The number of spraying ports blocked by the baffle 6 determines the width of the spraying; and the angle of the spraying can also be adjusted. Specifically, the motor II20 is started to drive the worm 19 to rotate, and the worm 19 drives the semi-worm gear 17 to rotate, thereby driving the support frame I16 to rotate, and further rotating the nozzle 1, thereby realizing the angle adjustment. When the motor III23 is started, it can also drive the screw rod II22 to rotate, thereby driving the horizontal slider 18 to move left and right, so that the route can be adjusted during spraying; The device can also use double-row spraying. At this time, the nozzle 1 slidably mounted on the slide rail II 31 will be started. When the electric push rod 27 is started, it drives the vertical slider 29 to slide up and down, and drives the horizontal sliders 18 on both sides to move on the slide rail II 31 through the connecting rod 30, thereby adjusting the distance between the two horizontal sliders 18, thereby adjusting the spacing between the two spraying lines.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
