Generally, the belt support assembly may include multiple bearings. During the movement of the conveyor belt, it can contact the bearing surface and drive the bearing to rotate. The belt support assembly provides support for the conveyor belt.

[0004] However, the surface of the bearing may become contaminated with moisture or dust, causing it to rust. Utility Model Content

[0005] The present invention aims to provide a belt support assembly, a fruit and vegetable conveying mechanism, and a fruit and vegetable sorting device to solve the technical problem in the prior art that the surface of the bearing may be contaminated with moisture or dust, leading to rust.

[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution: One embodiment of this utility model provides a belt support assembly, including: A fixed shaft component, the fixed shaft component comprising a base and a connecting rod connected to each other; A bearing component, which is sleeved on the connecting rod; A bushing component is rotatably connected to a fixed shaft component via a bearing component. The bushing component has a receiving cavity, the bearing component is located inside the receiving cavity, and the base covers the opening of the receiving cavity.

[0007] With the above structure, the bearing component is located inside the receiving cavity, and the base covers the opening of the receiving cavity; the conveyor belt can abut against the outside of the bushing component, the conveyor belt does not need to directly contact the bearing component, and the receiving cavity is sealed, so the bearing component is not easy to come into contact with liquid or debris on the conveyor belt, reducing the possibility of the bearing component rusting and improving the service life of the belt support assembly in this embodiment.

[0008] In some embodiments, the base includes a body and an annular wall, the body includes an abutting side, the connecting rod is connected to the abutting side, and the abutting side abuts against the bushing component and covers the opening of the receiving cavity; The annular wall is connected to the abutting side, and the annular wall protrudes toward the bushing component relative to the abutting side, and the annular wall is sleeved on the outside of the bushing component.

[0009] With the above structure, the annular wall is connected to the abutting side and is sleeved on the outside of the bushing component; the annular wall can cover the gap between the abutting side and the bushing component, further reducing the possibility of liquid or dust on the conveyor belt entering the receiving cavity, improving the sealing of the receiving cavity, and thus further reducing the possibility of bearing components rusting.

[0010] In some embodiments, the connecting rod includes a thick rod segment, a thin rod segment, and a first connecting portion. One end of the thick rod segment is connected to the abutting side, and the other opposite end of the thick rod segment is connected to the thin rod segment. One end of the thin rod segment facing away from the thick rod segment is detachably connected to the first connecting portion. The bearing component is sleeved on the thin rod segment, and the thick rod segment and the first connecting portion together clamp the bearing component.

[0011] With the above structure, the thicker rod segment and the first connecting portion together clamp the bearing component, ensuring a stable connection between the bearing component and the thinner rod segment. This prevents the bearing component from wobbling relative to the thinner rod segment during rotation, improving the stability of the belt support assembly in this embodiment. The thicker rod segment is located between the thinner rod segment and the abutting side, maintaining a certain distance between the bearing component and the opening of the receiving cavity. Even if some liquid or debris is located at the opening of the receiving cavity, it will not contact the bearing component.

[0012] In addition, the end of the thinner rod segment facing away from the thicker rod segment is detachably connected to the first connecting part. After the first connecting part is detached from the thinner rod segment, the bushing component and the bearing component can be removed to facilitate the replacement of the bushing component and the bearing component or the application of lubricating oil periodically.

[0013] In some embodiments, the bushing component includes a sleeve and a bottom cover, the sleeve having the receiving cavity, the abutting side abutting against the sleeve and covering the opening of the receiving cavity, and the annular wall being sleeved on the outside of the sleeve; The bottom cover is installed on the side of the sleeve facing away from the base, and the bottom cover is disposed on the first connecting part.

On the other hand, the bottom cover is provided on the first connecting part, and the bottom cover can prevent liquids or debris from contacting the first connecting part, thereby reducing the possibility of rust on the metal part of the first connecting part and improving the service life of the first connecting part.

[0015] In some embodiments, the bushing component further includes a retaining ring, the sleeve component has an annular retaining groove, the annular retaining groove communicates with the receiving cavity, and the bottom cover is located inside the receiving cavity; The retaining ring is installed in the annular retaining groove, the retaining ring portion is located in the receiving cavity, and the portion of the retaining ring located in the receiving cavity abuts against the side of the bottom cover facing away from the first connecting portion.

[0016] With the above structure, the portion of the retaining ring located inside the receiving cavity abuts against the side of the bottom cover facing away from the first connecting part. The retaining ring limits the bottom cover so that it is stably located inside the receiving cavity, thereby preventing the bottom cover from falling off relative to the sleeve.

[0017] In some embodiments, there are multiple bearing components, all of which are arranged sequentially along the central axis of the connecting rod, with adjacent bearing components fitting together.

[0018] With the above structure, there are multiple bearing components. All bearing components can work together to support the conveyor belt through the bushing component, so that the conveyor belt can run more stably and the stability of the belt support assembly is improved.

[0019] In some embodiments, the base portion is located within the receiving cavity, and the side surface of the base abuts against the cavity wall of the receiving cavity; The connecting rod includes a main body and a second connecting part. The bearing component is sleeved on the main body. One end of the main body is connected to the base, and the other opposite end of the main body is detachably connected to the second connecting part. The second connecting part and the base clamp the bearing component.

[0020] With the above structure, the base portion is located inside the receiving cavity, so that the bearing component can be stably installed inside the receiving cavity, and the portion of the base extending into the receiving cavity makes the bearing component a certain distance from the cavity opening, so that even if some liquid or debris is located at the cavity opening, it will not come into contact with the bearing component.

[0021] In addition, the second connecting part clamps the bearing component with the base; the bearing component does not need to be fixed to the main body of the connecting rod by welding or glue, which simplifies the assembly process of the belt support assembly.

[0022] In some embodiments, the bushing component includes an abutment protrusion connected to the cavity wall of the receiving cavity, the abutment protrusion abutting against the side of the bearing component facing the base.

[0023] With the above structure, the abutting protrusion abuts against the side of the bearing component facing the base, so that the abutting protrusion and the second connecting part can clamp the bearing component together. Thus, in the extension direction of the central axis of the connecting rod, the connecting rod, the bearing component and the bushing component are fixed to each other. The bearing component can be fixed relative to the bushing component without the need for welding or glue, which simplifies the assembly process of the belt support assembly.
