[0002] In automatic breeding, belt conveyor is needed in (egg picker and excrement cleaning machine etc.), so a large number of unpowered rollers are needed. In the prior art, the iron bearing seat is welded on the pipe body. In chicken house, duck house or rabbit house, there are a lot of excrement, the ammonia content in the air is high, and the damp excrement is easy to fall on the bearing seat from both sides of the conveying belt, so the iron bearing seat is easy to rust and rot, resulting in short service life of the roller.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] Detailed implementation method: combined with Figures 1-5As shown, a corrosion-resistant idler roller includes an idler roller shaft 1 and a tube body 2, and also includes two polymer bearing seats 3. The outer side of each bearing seat 3 is provided with an insertion part 31 for inserting into the end of the tube body 2. The outer diameter of the insertion part 31 is slightly larger than the inner diameter of the tube body 2, resulting in an interference fit between the two. The bearing seat 3 is provided with a bearing chamber 32 extending through its outer end (the end closest to the idler roller end is the outer end). The inner end of the bearing seat 3 is provided with a through hole through which the idler roller shaft 1 passes. A bearing 4 is disposed within the bearing chamber 32, with the outer ring of the bearing 4 fitting against the inner wall of the bearing chamber 32. The ring mates with the idler roller shaft 1. A polymer inner sealing cover 5 is provided inside the bearing chamber 32 on the outside of the bearing 4. The inner sealing cover 5 is interference-fitted with the bearing chamber 32. A channel 52 is provided in the center of the inner sealing cover 5. An insertion cylinder 62 is provided on the polymer outer sealing cover 6. The insertion cylinder 62 is tightly fitted around the outside of the idler roller shaft 1 and passes through the channel 52. The outer diameter of the insertion cylinder 62 is smaller than the inner diameter of the channel 52. The outer sealing cover 6 does not contact the bearing seat 3 or the inner sealing cover 5. A retaining spring is provided on the outside of both the bearing 4 and the outer sealing cover 6. The inner end of the insertion cylinder 62 contacts the retaining spring on the outside of the bearing 4. Interlocking protrusions are provided on the outside of the inner sealing cover 5 and the inside of the outer sealing cover 6, forming a labyrinth seal. During use, the idler roller shaft 1 and the outer sealing cover 6 do not rotate, while the tube body 2, bearing seat 3, and inner sealing cover 5 rotate. Because the bearing seat 3, inner sealing cover 5, and outer sealing cover 6 are all made of polymer material, they are not easily corroded. Since the inner sealing cover 5 and the outer sealing cover 6 are not easily corroded, they are easy to disassemble (if they are made of iron, they are not easy to disassemble after rusting), making it easy to replace the bearing.

[0017] Furthermore, the outer end of the bearing housing 3 is provided with a coaxial recess 33, and the inner sealing cover 5 is provided with a retaining ring 51. The outer diameter of the retaining ring 51 is larger than the diameter of the bearing chamber 32 and smaller than the diameter of the recess 33. The inner side of the retaining ring 51 contacts the bottom surface of the recess 33, serving a positioning function. The outer circumference of the outer sealing cover 6 is provided with a folded edge 61. The outer diameter of the folded edge 61 is larger than the outer diameter of the retaining ring 51 and slightly smaller than the diameter of the recess 33. The presence of the folded edge 61 makes it difficult for dust to enter the bearing chamber 32.

[0018] Furthermore, the outer sealing cover 6 has a ramp 611 on its outer side near its outer circumference, so that debris or water can easily fall down along the ramp 611.

[0019] Furthermore, the outer end of the recessed platform 33 is provided with a plurality of pushing plates 34. Preferably, the pushing plates 34 are disposed in the grooves on the outer side of the recessed platform 33, and the pushing plates 34 gradually tilt rearward in the direction of rotation from the outer end to the inner end. Figure 1As shown, when the bearing housing 3 rotates with the pipe body 2, the water falling from both sides of the conveyor belt falls onto the bearing housing 3 and flows down along its outer end face. It may then enter the location of the push plate 34. Since the push plate 34 rotates with the bearing housing 3, it can throw the water outward, thus making it difficult for the water to enter the bearing chamber 32.

[0020] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
