When there is no spraying instruction, the first protective cover 13 can cover the discharge pipe 11 to prevent rainwater and foreign objects from entering the discharge pipe 11. When there is a spraying instruction, the first driving member 12 drives the first protective cover 13 to rotate, so that the first protective cover 13 does not cover the discharge pipe 11. At this time, the discharge pipe 11 is in an open state, and the material can be sprayed out of the discharge pipe 11, thereby improving the protection level of the flower spraying machine.

[0037] In this embodiment, the rotation axis of the first protective cover 13 is parallel to the spraying direction of the discharge pipe 11.

[0038] A second protective cover 14 is fixed on the machine base 1. The second protective cover 14 covers the discharge pipe 11, and a spraying hole 141 facing the discharge pipe 11 is provided on the second protective cover 14.

[0040] Specifically, the first protective cover 13 includes a first plate body 131 opposite to the discharge pipe 11. Part of the edge of the first plate body 131 is provided with a first flange 132 extending towards the discharge pipe 11. The first plate body 131 is connected to the output end of the first driving member 12. The first flange 132 mainly reduces the intrusion of rainwater into the gap between the first plate body 131 and the discharge pipe 11.

[0041] The second protective cover 14 includes a second plate body 142 opposite to the discharge pipe 11. A part of the edge of the second plate body 142 is provided with a second baffle 143 extending towards the discharge pipe 11. The second plate body 142 is connected to the machine base 1, and the second baffle 143 is to prevent the first protective cover 13 from being collided. The injection holes 141 are arranged on the second plate body 142;

[0042] A first notch is formed between the edge of the first plate body 131 without the first baffle 132 and the machine base 1. The first notch allows the discharge pipe 11 to pass through, ensuring that the first protective cover 13 is not affected by the discharge pipe 11; A second notch is formed between the edge of the second plate body 141 without the second baffle 142 and the machine base 1. The second notch allows the first protective cover 13 to pass through, ensuring that the first protective cover 13 is not affected by the second baffle 142.
