[0032] The fan housing 1 includes a housing body 101, a noise reduction groove 102, and a mounting base 103. The inner wall of the housing body 101 is provided with a noise reduction groove 102, and the mounting base 103 is fixedly connected to the inner wall of the housing body 101.

[0033] The connecting seat 6 includes an adjusting seat 601, a sleeve 602, an angle scale line 603, a worm gear 604, an internal hexagonal connector 605, an angle pointer 606, a mounting pivot 607, a worm wheel 608, a slot 609, and a locking hole 610. The sleeve 602 is fixedly connected to the outside of the adjusting seat 601. An angle scale line 603 is provided on the outside of the sleeve 602. The worm gear 604 is rotatably connected inside the adjusting seat 601. An internal hexagonal connector 605 is fixedly connected to the end of the worm gear 604 near the sleeve 602. An angle pointer 606 is provided on the outside of the internal hexagonal connector 605. The mounting pivot 607 is provided at the end of the adjusting seat 601 away from the turntable 5. The worm wheel 608 is fixedly connected to the end of the mounting pivot 607 near the turntable 5. A slot 609 is provided at the end of the mounting pivot 607 away from the adjusting seat 601. A locking hole 610 is provided on the outside of the mounting pivot 607.

[0034] Specifically, the noise reduction groove 102 has a grid-like structure, and the fixing base 2 includes a ring seat 201 and a support pipe 202. The support pipe 202 is fixedly connected to the outside of the ring seat 201, and the support pipe 202 is welded to the mounting base 103. The advantage is that the grid-like structure of the noise reduction groove 102 can reflect and weaken sound waves multiple times, effectively absorbing and dispersing the noise generated during the operation of the fan, reducing the impact of noise on the working environment, and providing relatively quiet working conditions for operators.

[0035] Specifically, there are two symmetrically arranged fixed seats 2. Fixed seats 2 and ring seats 3 are locked together by bolts. Motor 4 is also locked together with ring seats 3 and ring seats 201 by bolts. The advantage is that the installation and disassembly of motor 4 with ring seats 3 and ring seats 201 by bolts is convenient, which facilitates the maintenance and repair of the equipment.

[0036] Example 2: Figures 2-5 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, the hex socket 605 and the sleeve 602 are rotatably connected, and the angle scale line 603 corresponds to the angle pointer 606. The advantage is that the rotatable connection between the hex socket 605 and the sleeve 602 allows operators to easily rotate the hex socket 605 using tools such as an Allen wrench. The corresponding setting of the angle scale line 603 and the angle pointer 606 provides an intuitive reference for angle adjustment, enabling precise adjustment of the angle of the blade assembly 7. This precise angle adjustment function allows the fan to flexibly adjust the direction and intensity of the airflow output according to different coal preparation needs, improving coal preparation efficiency and quality.

[0038] Specifically, the worm gear 608 extends into the adjusting seat 601, the worm 604 is meshed with the worm gear 608, and the mounting swivel 607 is rotatably connected to the adjusting seat 601. The advantage is that the meshing connection between the worm 604 and the worm gear 608 has a self-locking characteristic. The operator can rotate the Allen wrench or other tools to rotate the Allen connector 605, causing the worm 604 to rotate accordingly. This allows for precise control of the rotation of the worm gear 608 and the mounting swivel 607, thereby achieving precise adjustment of the blade assembly 7 angle. The self-locking performance of the worm gear 608 and the worm 604 ensures that the adjusted blade assembly 7 angle remains stable and will not change due to vibrations or other factors during wind turbine operation.

[0039] Specifically, the blade assembly 7 includes a blade body 701 and a plug 702, with the plug 702 located at the end of the blade body 701 near the mounting pivot 607. The advantage of this design is that the plug 702 facilitates the connection between the blade body 701 and the mounting pivot 607. When the blade body 701 is damaged or needs replacement, it can be quickly replaced, reducing equipment downtime and improving maintenance efficiency.

[0040] Specifically, the plug 702 and the slot 609 are connected by a plug-in joint, and the slot 609 and the plug 702 are locked together by a locking bolt. The advantage is that during assembly, the plug 702 is inserted into the slot 609, and the locking bolt is passed through the locking hole 610 to lock the mounting bracket 607 and the blade assembly 7.

[0041] Working Principle: During use, according to different coal preparation requirements, the operator can precisely control the rotation of the worm gear 608 and the mounting swivel 607 by turning the Allen wrench around the Allen connector 605, thereby precisely adjusting the angle of the blade assembly 7. The fan can flexibly adjust the direction and intensity of the wind output, improving coal preparation efficiency and quality, and meeting diverse production process requirements. The noise reduction grooves 102 set on the inner wall of the fan casing 1 have a grid structure, which can reflect and weaken the sound waves generated by the fan multiple times, effectively absorbing and dispersing noise, reducing noise pollution to the working environment, and creating a relatively quiet working condition for the operator. The motor 4 is fixed to the ring seat 3, the ring seat 201, and the fixed seat 2 is fixed to the ring seat 3 by bolts. The installation and disassembly of the axial flow fan is very convenient. When a component of the axial flow fan fails, maintenance personnel can quickly disassemble and replace it, greatly shortening the equipment downtime, improving equipment maintenance efficiency, and reducing maintenance costs.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
