Description

Technical Field

[0001] The utility model belongs to the technical field of ear picking rollers, and particularly relates to a dustproof and waterproof sealing structure of an ear picking roller. Background Art

[0002] The ear picking roller is one of the important components on the cutting table of a corn harvester. It is generally rotatably connected to the cutting table through a bearing support. There is an inevitable assembly gap between the stem pulling roller and the guide cone of the ear picking roller and the two sides of the bearing support, and impurities, rainwater, etc. can easily enter, thereby causing wear or oxidation corrosion to the internal bearing components. There is no very effective dustproof and waterproof structure in the existing technology. Generally, the dustproof and waterproof seal of the bearing component is relied on the dustproof cover of the bearing component, but the effect is limited. Utility Model Content

[0003] The utility model provides a dustproof and waterproof sealing structure of an ear picking roller, which can solve the problems pointed out in the background technology.

[0004] A dustproof and waterproof sealing structure for an ear picking roller comprises a bearing support, a stem pulling roller and an introduction cone assembled on both sides of the bearing support, the bearing support comprises a bearing sleeve and a bearing assembly, a first cone ring is provided at the connecting end between the bearing sleeve and the stem pulling roller, and a first inner cone surface which cooperates and matches with the first cone ring is provided on the connecting end of the stem pulling roller.

[0005] Preferably, a second cone ring is provided at the connecting end of the bearing sleeve and the introduction cone, and a second inner cone surface that cooperates and matches with the second cone ring is provided on the connecting end of the introduction cone.

[0006] Preferably, a first dust ring is provided on one side of the bearing assembly close to the connecting end of the stem pulling roller.

[0007] Preferably, a second dust ring is provided on one side of the bearing assembly close to the connecting end of the introduction cone.

[0008] The utility model provides a dustproof and waterproof sealing structure of an ear picking roller, and a conical surface structure is arranged. When the stem pulling roller rotates, centrifugal force is generated, and impurities are easily thrown away under the guidance of the conical surface, thereby effectively preventing them from entering the bearing assembly;

[0009] Providing a dustproof ring can further effectively achieve the effect of sealing against dust and water, and improve the sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0016] Embodiment 1:

[0017] like Figure 1-3 As shown, an embodiment of the utility model provides a dustproof and waterproof sealing structure for an ear picking roller, comprising a bearing support 1, a stem pulling roller 2 and an introduction cone 3 assembled on both sides of the bearing support 1, the bearing support 1 comprising a bearing sleeve 11 and a bearing assembly 12, a first cone ring 13 is provided at the connecting end between the bearing sleeve 11 and the stem pulling roller 2, a first inner cone surface 21 which cooperates and matches with the first cone ring 13 is provided on the connecting end of the stem pulling roller 2, and the cooperation between the first cone ring 13 and the first inner cone surface 21 can be a clearance cooperation.

[0018] In some embodiments, a second cone ring 14 is provided at the connecting end between the bearing sleeve 11 and the introduction cone 3, and a second inner cone surface 31 which cooperates and matches with the second cone ring 14 is provided on the connecting end of the introduction cone 3. The cooperation between the second cone ring 14 and the second inner cone surface 31 can be a clearance cooperation.

[0019] In some embodiments, a first dust ring 15 is provided on one side of the bearing assembly 12 close to the connecting end of the stem pulling roller 2 .

[0020] In some embodiments, a second dust ring 16 is provided on one side of the bearing assembly 12 close to the connection end of the introduction cone 3 .

[0021] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
