DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5 , the present utility model provides a technical solution: An environment-friendly gyratory crusher, including an upper frame 1, the inner wall top end of the upper frame 1 is provided with a housing 2, the housing 2 is hinged with annularly arranged spray heads 3, the lower ends of the spray heads 3 extend to the lower end of the housing 2, a drive assembly for driving the spray heads 3 to deflect outward is installed in the housing 2, an annular water guide chamber 4 is installed in the housing 2, and the water inlet ends of the spray heads 3 are connected to the joints on the annular water guide chamber 4 through hoses.

[0019] The housing 2 is sleeved on the main shaft installed on the upper frame 1 and does not contact the main shaft. The spray heads 3 are distributed around the main shaft.

[0020] The housing 2 includes an annular mounting base 21. The annular mounting base 21 is installed at the top end of the inner wall of the upper frame 1. The annular water guide chamber 4 is installed on the annular mounting base 21. A connecting ring 22 is installed at the inner side end of the annular mounting base 21. A circular fixing plate 23 is installed at the lower end of the connecting ring 22. The spray head 3 is hinged to the circular fixing plate 23.

[0021] A protective plate 5 is installed on the outer side wall of the circular fixing plate 23, and the upper end of the protective plate 5 is connected to the annular mounting base 21.

[0022] The driving assembly includes a limiting ring 6 sleeved on the connecting ring 22. Symmetric electric telescopic rods 7 are installed on the circular fixing plate 23. The extending ends of the electric telescopic rods 7 are connected to the limiting ring 6. A connecting rod 8 is hinged between the spray head 3 and the limiting ring 6.

[0023] The hinged position of the spray head 3 and the circular fixing plate 23 is lower than the hinged position of the spray head 3 and the connecting rod 8.

[0024] The limiting ring 6 is located inside the ring formed by the annularly distributed spray heads 3. The limiting ring 6 is hinged to the spray head 3 through the connecting rod 8. The connecting rod 8 is hinged to the bottom surface of the limiting ring 6, and the connecting rod 8 is inclined after connection.

[0025] A communicating pipe 9 is installed on the outer side wall of the upper frame 1. The water delivery pipe of the annular water guide chamber 4 extends out through the communicating pipe 9 for connection with a water supply device.

[0026] Working principle: When the present utility model is in use, the annular water guide chamber 4 is connected to a water supply device through a water delivery pipe. The water supply device is started, and water enters the annular water guide chamber 4 and reaches each spray head 3 through a hose. The spray heads 3 spray water on the surface of the crushing chamber and the incoming material, reducing the generation of dust during crushing. Moreover, the water sprayed by the spray heads 3 can settle the generated dust. The electric telescopic rods 7 are started, and the electric telescopic rods 7 drive the limiting ring 6 to move up and down. The limiting ring 6 is sleeved on the connecting ring 22 to limit it. Since the spray head 3 is hinged to the limiting ring 6 through the connecting rod 8, the spray head 3 is driven to rotate towards the outer side end, increasing its spraying range.
