DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0033] Example

[0034] Reference Figures 1-9 As shown, the utility model is a wear-resistant wood-plastic blower, comprising:

[0035] The outer shell 6 is provided with an air inlet 1 and an air outlet;

[0036] A drive motor 4 is provided on one side of the outer shell 6;

[0037] The blade mechanism 11 includes: a first support body 2, blades 113, and a second support body 3. The first support body 2 is rotatably connected to the outer shell 6 and connected to the output end of the drive motor 4. The blades 113 are multiple and connected to the first support body 2. The second support body 3 is connected to the ends of the blades 113.

[0038] The wear-resistant mechanism includes: a first lining plate 115 and a second lining plate 111 respectively arranged on both sides of the blade 113, the first lining plate 115 is provided with a blind hole 116, the second lining plate 111 is provided with a plurality of studs 112, the blade 113 is provided with a through hole 117, a nut 114 is embedded in the through hole 117, and the end of the stud 112 can pass through and extend to the blind hole 116.

[0039] The utility model discloses a wear-resistant wood-plastic blower. The output shaft of the motor drives the first support body 2 of the blade mechanism 11 to rotate. Since the blade 113 is connected to the first support body 2, the blade 113 rotates together with the first support body 2. During the rotation of the blade 113, air is sucked in from the air inlet 1 of the outer shell 6. As the blade 113 rotates, the air is pushed and centrifuged by the blade 113 and then discharged from the outer air outlet. Since the blade 113 rubs against materials such as wood powder and talcum powder during high-speed rotation, the friction of the material is borne by the first lining plate 115 and the second lining plate 111, thereby reducing the wear of the blade 113 body. When the first lining plate 115 and the second lining plate 111 are excessively worn, The first lining plate 115 and the second lining plate 111 are disassembled and replaced through the connection structure of the stud 112, the nut 114 and the blind hole 116. The blind hole 116 of the first lining plate 115 and the stud 112 of the second lining plate 111 are both arranged on the side close to the blade 113, so that the outer surfaces of the first lining plate 115 and the second lining plate 111 remain smooth. Not only can the lining plates be easily replaced, thereby extending the service life of the entire blade mechanism 11 and ensuring the normal operation of the fan, but the outer surface of the first lining plate 115 and the outer surface of the second lining plate 111 are smooth and do not have countersunk holes, which can reduce turbulence to ensure aerodynamic efficiency and reduce aerodynamic noise during high-speed rotation, and reduce surface wear and increase the service life of the lining plates.

[0040] The through hole 117 of the blade 113 is a stepped hole, the large diameter of the stepped hole is close to the first lining plate 115, the nut 114 is rotatably connected to the large diameter of the stepped hole, and the stud 112 passes through the small diameter and large diameter of the stepped hole.

[0041] As shown in FIG3 , a plurality of slots 12 are formed on the first side of the first support body 2. The shape of the slots 12 is adapted to fit the first liner 115 and the second liner 111. When the blade mechanism 11 rotates at high speed, the first and second liner 115, 111 are embedded in the slots 12 of the first support body 2, and centrifugal force causes the liner to move outward. The shape of the slots 12 limits the radial movement of the liner, ensuring that the liner always fits tightly against both sides of the blade 113, effectively withstanding the forces generated by friction between the blade 113 and external objects.

[0042] The shapes of the first liner 115 and the second liner 111 are adapted to the blade 113, and the first liner 115 and the second liner 111 respectively cover the first side and the second side of the blade 113, so that the first liner 115 and the second liner 111 are in contact with each other. During high-speed rotation, the first liner 115 and the second liner 111 have a centrifugal tendency, and the first liner 115 is supported by the fixed blade 113. The blade 113 also pulls the second liner 111 through the nut 114 and the stud 112. At the same time, the end of the stud 112 extends into the blind hole 116 of the first liner 115, forming a frame lock for the first liner 115 to prevent the first liner 115 from deformation, so that the first liner 115 can be in contact with the blade 113.

[0043] Reference Figure 3 、 Figure 6 As shown, the blade 113 is spirally arranged, and the first side of the blade 113 is the side of the blade 113 close to the spiral center, and the second side of the blade 113 is the side of the blade 113 away from the spiral center.

[0044] Reference Figure 5 As shown, the circumferential side of the nut 114 is rotatably connected to the inner wall of the through hole 117. During the assembly and disassembly process of the second lining 111, the first lining 115 is first destroyed and removed, and then the nut 114 is rotated to disengage the nut 114 from the blade 113, thereby releasing the lock on the second lining 111.

[0045] Reference Figure 5 As shown, the stud 112 is arranged on one side of the second lining plate 111 close to the blade 113, and the depth of the blind hole 116 is not greater than the thickness of the first lining plate 115, so that the stud 112 does not pass through the first lining plate 115, keeping its surface smooth.

[0046] The second support body 3 is provided with an air inlet hole, and the air inlet hole, the spiral center of the blade 113 and the air inlet 1 of the outer shell 6 correspond to each other.

[0047] Reference Figure 7 As shown, a bolt 10 is provided on the second side of the first support body 2, and the bolt 10 passes through the second support body 3 and is connected to the blade 113, so that the air is more evenly distributed between the blades 113 when entering the blade mechanism 11, reducing the resistance to air flow, thereby improving the overall working efficiency of the fan.

[0048] A plurality of card slots 12 are provided on the first side of the first support body 2. The size of the card slots 12 is adapted to the first lining plate 115. The height of the first lining plate 115 is greater than that of the second lining plate 111, and one side of the first lining plate 115 extends into the card slot 12. Since the surface of the first lining plate 115 is subjected to a greater extrusion force, the bottom of the first lining plate 115 is extended into the card slot 12, thereby improving the stability of the first lining plate 115.

[0049] The fan is also provided with a base 5. The air outlet of the outer shell 6 is connected to an air outlet duct 8, which is arranged on one side of the base 5. The base 5 provides support for the fan and ensures its stability. Furthermore, the arrangement of the air outlet duct 8 on the side of the base 5 makes the fan layout more compact and reasonable. While meeting air delivery requirements, it also facilitates connection and collaboration with other equipment or systems.

[0050] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
