However, the existing dust suppression machines have a limited spray dust reduction range and the spray direction cannot be adjusted in multiple directions, resulting in limited dust reduction effects.

[0012] By adopting the above technical solution, after the motor is started, the movable seat can be driven to rotate without affecting the water delivery of the delivery pump, thereby providing power for subsequent spray angle adjustment.

[0013] Preferably, the movable seat and the spray piece in the middle are connected by a pipe, and the length of the pipe between the movable seat and the spray piece in the middle is greater than the length of the slide groove, and the spray piece in the middle and the spray pieces on both sides are connected by a pipe, and spray holes are evenly arranged on the upper surface of the spray piece.

[0029] Furthermore, a slide groove and an adjustment block are provided. As the movable frame rotates and swings, the spraying member drives the adjustment block to slide back and forth on the inner side of the slide groove under the action of gravity, thereby further adjusting the spraying radius of the spraying member and further expanding the spraying range.

[0030] 2. A support member is provided. When the motor is started, the support member can be driven to rotate intermittently through the transmission of the second gear and the inner gear ring, so as to adjust the position of the wave crest and the wave trough on the support member, so that the movable frame can rotate at different positions with different amplitudes, thereby improving the uniformity of the spray after adjustment;
