The air resistance of each fan blade of the existing industrial fan is different in the operation process, the stress of the fan blades can enable the whole fan to generate resonance, the stress can be concentrated on the motor, the load of the motor is increased, and the service life of the motor is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model provides an industrial fan structure that flabellum angle can be finely tuned is used for overcoming among the prior art on the stress of flabellum can concentrate on the motor, makes the motor load strengthen, the defect that the life-span reduces.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model discloses an industrial fan structure that flabellum angle can be finely tuned, including the rim plate, follow the circumferencial direction equipartition of rim plate has a plurality of fan handles, be equipped with the bush in the through-hole of fan handle one end, be equipped with the injecting glue district in the bush, the reinforcement passes through the fastener and is connected with the fan handle.
Further, the fan blade is connected with the reinforcing piece and the fan handle through fasteners.
Furthermore, both ends of the reinforcing member are provided with hollow parts matched with the fan handle and the root part of the fan blade.
Furthermore, the fan handle is arranged in a manner that the thickness of two ends is less than that of the middle section, a through hole is formed in the upper plane of one end, far away from the wheel disc, of the fan handle, and a bushing is assembled in the through hole.
Furthermore, a glue injection area is arranged between the inner ring and the outer ring of the bushing, so that the bushing has the functions of buffering and damping.
Furthermore, the fan blades are arranged in the liner of the fan handle, and the angle fine adjustment effect of the fan blades is achieved through the glue injection area.
The utility model discloses the beneficial effect who reaches is: because the air resistance of each fan blade is different in the running process of the fan, the glue injection area has certain deformation, so that a buffer area is formed between the fan handle and the bushing, the fan blades arranged in the bushing through the fasteners can have a certain angle fine adjustment range, the fan blades can make corresponding angle adjustment according to the air resistance, and the stress of the fan blades is prevented from being concentrated on the motor, so that the load of the motor is increased, and the service life is shortened; in addition, the glue injection area also has the effect of buffering and damping, so that the rotation of the fan blades is smoother, the power consumption and the noise are reduced, and the working environment is better.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Example 1
As shown in fig. 1-4, an industrial fan structure with finely adjustable fan blade angle comprises a wheel disc 1, a plurality of fan handles 2 are uniformly distributed along the circumferential direction of the wheel disc 1, a bushing 3 is arranged in a through hole at one end of each fan handle 2, a glue injection area 5 is arranged in each bushing 3, and a reinforcing member 4 is connected with the fan handles 2 through a fastening member.
The fan blades are connected with the reinforcing member 4 and the fan handle 2 through fasteners.
The fan handle 2 is arranged with the thickness of two ends less than the thickness of the middle section, the upper plane of one end of the fan handle 2 far away from the wheel disc 1 is provided with a through hole, and a lining 3 is assembled in the through hole.
And a glue injection area 5 is arranged between the inner ring and the outer ring of the bushing 3, so that the bushing has the functions of buffering and damping.
The fan blades are arranged in the bushings 3 of the fan handle 2, and the fan blades have the effect of fine adjustment of angles through the glue injection area 5.
Both ends of the reinforcing piece 4 are provided with hollow parts matched with the fan handle 2 and the root part of the fan blade.
The working principle is as follows: the upper plane of one end of the fan handle 2 is provided with a through hole, a bushing 3 is assembled in the through hole, and a glue injection area 5 is arranged between an inner ring and an outer ring of the bushing 3, because the air resistance of each fan blade in the running process of the fan is different, the glue injection area 5 has a certain deformation amount, so that a buffer area is formed between the fan handle 2 and the bushing 3, the fan blades arranged in the bushing 3 through a fastener can have a certain angle fine adjustment range, the fan blades can make corresponding angle adjustment according to the air resistance, and the stress of the fan blades is prevented from being concentrated on a motor, so that the load of the motor is increased, and the service life is shortened; in addition, injecting glue district 5 still has the absorbing effect of buffering, can make the rotation of flabellum more smooth and easy, reduces power consumption and noise, makes operational environment better.
