[0003] When in use, the spray head needs to be fixedly connected to the water pipe and fixedly installed by a supporting device. In the prior art, after the spray head is fixedly installed, it can only spray in the direction of the fixed installation, which has certain limitations. When it is necessary to spray at positions of different angles, the angle cannot be adjusted as required, resulting in uneven pesticide spraying and inability to effectively disinfect pests and diseases. The practicality is insufficient. Therefore, it is necessary to redesign a multi-angle spray head to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A multi-angle spray head includes a spray head body 1, a connecting pipe 2 and a bottom plate 3. A lifting frame 4 is fixedly installed on the upper end surface of the bottom plate 3. A screw 5 is rotatably installed inside the lifting frame 4. A first motor 6 connected to the screw 5 is fixedly installed on the upper end surface of the lifting frame 4. A moving plate 7 is threadedly installed on the outer wall of the screw 5. The upper end surface of the moving plate 7 is connected to a connecting plate 9 through a connecting mechanism. The connecting mechanism includes two connecting rods 8 fixedly installed on the upper end surface of the moving plate 7. The ends of the two connecting rods 8 are fixedly connected to the bottom wall of the connecting plate 9. With the cooperation of the two connecting rods 8, the movable plate 7 can be restricted so that it can only move axially along the outer wall of the screw rod 5. A rotating shaft 10 is rotatably installed on the upper end surface of the connecting plate 9, and a first gear 11 is fixedly installed on the outer wall of the rotating shaft 10. A second motor 12 is fixedly installed on the upper end surface of the connecting plate 9. The outer wall of the output shaft of the second motor 12 is connected to the first gear 11 through a rotating mechanism. The rotating mechanism includes a second gear 13 fixedly installed on the outer wall of the output shaft of the second motor 12, and the second gear 13 is engaged with the first gear 11.

[0024] A fixing plate 14 is fixedly installed on the end of the rotating shaft 10, and a connecting frame 15 is fixedly installed on the upper end surface of the fixing plate 14. A connecting rod 16 is fixedly installed inside the connecting frame 15. A connecting block 18 is rotatably installed on the outer wall of the connecting rod 16 through an elastic mechanism. The elastic mechanism includes a torsion spring 17 installed on the outer wall of the connecting rod 16, and the two ends of the torsion spring 17 are elastically connected to the outer wall of the connecting rod 16 and the inner wall of the connecting block 18 respectively. An electric push rod 20 is fixedly installed on the upper end surface of the fixing plate 14, and a pulley 21 is fixedly installed on the telescopic end of the electric push rod 20. A fixing sleeve 19 is fixedly installed on the end of the connecting block 18, and a bolt 22 is rotatably installed on the outer wall of the fixing sleeve 19. A lower pressure plate 23 is rotatably installed on the end of the bolt 22. The lower pressure plate 23 is an arc-shaped inner wall, and the lower pressure plate 23 of the arc-shaped inner wall can better fit the outer wall of the connecting pipe 2.

[0025] When the utility model is used, the bottom plate 3 is fixedly installed on the ground, the spray head body 1 and the connecting pipe 2 are connected and fixed, and then the connecting pipe 2 can be inserted into the fixing sleeve 19, and the bolt 22 is rotated to drive the lower pressing plate 23 to move downward inside the fixing sleeve 19, so that the outer wall of the connecting pipe 2 can be pressed down and fixed by the lower pressing plate 23. When spraying, the first motor 6 drives the screw rod 5 to rotate, and the screw rod 5 drives the moving plate 7 to move inside the lifting frame 4. The moving plate 7 can drive the connecting plate 9 to move up and down through the cooperation of the two connecting rods 8, so that the spray head body 1 can be driven to move up and down through the connecting plate 9, thereby realizing convenient adjustment of the spraying height;

[0026] The second motor 12 can drive the second gear 13 to rotate. At this time, the second gear 13 can drive the rotating shaft 10 to rotate by engaging the first gear 11. The rotation of the spray head body 1 can be realized by the drive of the rotating shaft 10, so as to spray at different positions. When it is necessary to spray at different angles, the electric push rod 20 drives the pulley 21 to move upward, and the pulley 21 can apply an upward force to the fixed sleeve 19, and the pulley 21 also slides on the outer wall of the fixed sleeve 19. At this time, the fixed sleeve 19 is subjected to force to drive the connecting block 18 to rotate on the outer wall of the connecting rod 16, thereby conveniently adjusting the inclination angle of the spray head body 1 and changing the curve of the pesticide during spraying. While rotating, the connecting block 18 will also drive the torsion spring 17 to contract. When the electric push rod 20 drives the pulley 21 to move downward and reset, the torsion spring 17 releases its elastic potential energy to drive the connecting block 18 and the fixed sleeve 19 to rotate and reset.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
