Technical Field

[0001] This utility model relates to the technical field of corn harvester accessories, specifically to a tracked corn harvester gear. Background Technology

[0002] Tracked harvesters are mechanical devices driven by tracks, used for harvesting and baling crops. Depending on the crop being harvested, they can be divided into specialized models for wheat, rice, soybeans, corn, etc. Tracked corn harvesters can simultaneously complete corn ear picking, corn husking, corn ear collection, and corn stalk crushing and returning to the field, greatly improving the efficiency and quality of corn harvesting.

[0003] Currently, tracked harvesters use a large number of gears. However, the current gear structure is simple and is generally a one-piece structure. The gears used in harvesters bear a large load, which can easily cause the teeth on the gears to break or wear. When replacing a one-piece gear, the entire gear must be replaced, which increases the cost. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a tracked corn harvesting gear, which is divided into three parts, all of which can be replaced, so as to solve the problem mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a tracked corn harvesting gear, comprising a middle ring, an outer ring, and multiple inner rings. The inner rings are arranged one in front of the other inside the middle ring. The outer ring is composed of multiple arc-shaped parts, which are arranged in a ring structure on the outer surface of the middle ring. The outer surface of the arc-shaped parts is raised to form convex teeth. The multiple convex teeth are evenly distributed in a ring structure. The opposite end faces of the inner rings abut against each other. The opposite end faces of the inner rings are bent outward to form a ring-shaped pressing part. The pressing part abuts against the sides of the middle ring and the outer ring.

[0006] As a preferred technical solution, each of the opposite surfaces of the inner ring is provided with an arc-shaped groove, and the opposite arc-shaped grooves are combined to form a fixing groove. Each arc-shaped groove is equipped with a half-column, and the opposite half-columns are combined to form a stud. The stud is threaded with a nut that presses the inner ring inward and positions it.

[0007] As a preferred technical solution, the outer end faces of both the stud and the nut are set with an arc-shaped structure, and the degree of arc of the arc structure matches the degree of arc of the inner ring on the inner ring.

[0008] As a preferred technical solution, both sides of the arc-shaped part are provided with pressure grooves, and the pressure grooves are all arranged in an arc-shaped structure. Multiple pressure grooves on each side are combined to form an annular groove. The inner surface of the pressing part is equipped with a pressing ring facing the annular groove. The pressing rings are all inserted into the annular groove and are all in contact with the inner wall surface of the annular groove.

[0009] As a preferred technical solution, the outer ring surface of the inner ring is provided with external threads, and the inner wall surface of the openings at both ends of the middle ring is provided with internal threads. The inner ring is connected to the middle ring by the engagement of the external threads with the internal threads.

[0010] As a preferred technical solution, the outer ring surface of the middle ring is provided with multiple connecting grooves distributed in an annular structure. The inner ring surface of the arc-shaped component protrudes to form connecting parts opposite to the connecting grooves. The connecting parts are all inserted into the connecting grooves, and both the connecting parts and the connecting grooves are arranged in a fan-shaped structure.

[0011] The beneficial effects of this utility model are: the utility model has a simple structure, the gear is divided into three parts, consisting of an inner ring, a middle ring and an outer ring. After rotating the inner ring outward, the inner ring, the middle ring and the outer ring can be separated. The outer ring is composed of multiple arc-shaped parts. If the convex teeth on any arc-shaped part are damaged, only the corresponding arc-shaped part needs to be replaced. Once the inner ring is worn, the inner ring can be replaced, which greatly increases adaptability and reduces cost. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0019] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a tracked corn harvesting gear of this utility model includes a middle ring 7, an outer ring, and multiple inner rings 2. The inner rings 2 are arranged one in front of the other inside the middle ring 7. The outer ring is composed of multiple arc-shaped parts 1. The arc-shaped parts 1 are arranged in a ring structure on the outer ring surface of the middle ring 7. The outer ring surface of the arc-shaped parts 1 is raised to form convex teeth. The multiple convex teeth are evenly distributed in a ring structure. The opposite end faces of the inner rings 2 are abutted together. The opposite end faces of the inner rings 2 are bent outward to form a ring structure pressing part 3. The pressing part 3 is abutted together with the sides of the middle ring 7 and the outer ring.

[0021] In this embodiment, arc-shaped grooves 4 are provided on opposite surfaces of the inner ring 2. The opposite arc-shaped grooves 4 are combined to form a fixing groove. Half-columns are installed in the arc-shaped grooves 4. The opposite half-columns are combined to form studs 5. Nuts 6 that press the inner ring 2 inward and position it are threadedly connected to the outside of the studs 5.

[0022] In this embodiment, the outer end faces of both the stud 5 and the nut 6 are arc-shaped, and the degree of arc of the arc structure matches the degree of arc of the inner ring on the inner ring 2.

[0023] In this embodiment, both sides of the arc-shaped component 1 are provided with pressure grooves, and the pressure grooves are all arranged in an arc-shaped structure. Multiple pressure grooves on each side are combined to form an annular groove 9. A clamping ring 10 is installed on the inner side of the clamping part 3 opposite to the annular groove 9. The clamping ring 10 is inserted into the annular groove 9 and is in contact with the inner wall surface of the annular groove 9. The annular groove and the clamping ring can connect the outer ring and the inner ring, increasing the contact area and the overall installation firmness.

[0024] In this embodiment, the outer ring surface of the inner ring 2 is provided with external threads, and the inner wall surface of the openings at both ends of the middle ring 7 is provided with internal threads. The inner ring 2 is connected to the middle ring 7 by the engagement of the external threads with the internal threads of the middle ring 7. The connection between the inner ring and the middle ring is strengthened by the threaded connection.

[0025] In this embodiment, the outer ring surface of the middle ring 7 is provided with multiple connecting grooves distributed in an annular structure. The inner ring surface of the arc-shaped component 1 protrudes to form connecting parts 8 at the connecting grooves. The connecting parts 8 are all inserted into the connecting grooves. The connecting parts 8 and the connecting grooves are arranged in a fan-shaped structure, so that the arc-shaped component and the middle ring are connected and separation is avoided.

[0026] During installation, the connecting part on the arc-shaped part is inserted into the connecting groove, and the inner ring is threaded into the openings at both ends of the middle ring. As the inner rings approach, the clamping ring on the clamping part can be inserted into the annular groove. After the inner rings come into contact, the half-pillars can fit together to form a stud. The inner side of the clamping part comes into contact with the outer side of the middle and outer rings, and the clamping ring can come into close contact with the inner wall of the annular groove. The connection and fixation between the inner ring, middle ring and outer ring can be directly completed through the inner ring.

[0027] After the above is completed, the nut can be threaded onto the stud, and the inner ring can be directly fixed by the nut, which avoids separation between the inner rings and increases the stability after installation;

[0028] The inner ring can be fitted onto any rotating shaft by shrinking through liquid nitrogen cooling. After fitting, the outer end faces of the nut and stud can abut against the outer wall of the rotating shaft, thus preventing the nut from shifting outward and affecting the overall stability of the installation.

[0029] In this design, if the arc-shaped component or the inner ring is damaged, the nut can be unscrewed, causing the inner ring to rotate outward. After the inner ring is removed from the middle ring, the arc-shaped component can be disassembled outward along the connecting groove, allowing the outer ring, middle ring, and inner ring to be separated. All three can be replaced, reducing costs through independent replacement.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
