Description

Technical Field

[0001] This utility model relates to the technical field of agricultural machinery, specifically to a front wheel of a rice transplanter. Background Technology

[0002] In agricultural production, rice transplanters are widely used as efficient planting equipment, and the stability of their walking system directly affects transplanting accuracy and work efficiency. When assembling the front and rear wheels of traditional rice transplanters, the wheel hub center and the wheel rim center axis are often collinear, making it difficult to match the wheel track. This necessitates the addition of additional bushings to adjust the front wheel position to ensure that the front and rear wheels travel on the same line.

[0003] However, this adjustment method relying on bushings has significant drawbacks: on the one hand, the addition of bushings increases the number of parts, raising production and assembly costs; on the other hand, bushings are prone to loosening and wear during long-term operation, leading to misalignment of the front and rear wheels. This not only affects the straight-line driving performance of the rice transplanter but may also cause uneven row spacing for seedlings, reducing operational quality. Furthermore, the additional bushing structure increases the overall weight of the front wheels, increasing power consumption and hindering energy conservation. Therefore, there is an urgent need for a rice transplanter front wheel structure that can achieve co-alignment of the front and rear wheels without relying on bushings, to address the shortcomings of existing technologies. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a front wheel for a rice transplanter, addressing the aforementioned shortcomings of the prior art.

[0005] To achieve its purpose, this utility model adopts the following technical solution:

[0006] A front wheel for a rice transplanter includes: a wheel rim, a hub center, and a support frame connecting the wheel rim and the hub center; the support frame is bent, and through the bending structure of the support frame, the hub center is offset outward relative to the central axis of the wheel rim, so that the assembled front wheel and rear wheel of the rice transplanter can be kept collinear without the need for an additional bushing.

[0007] Preferably, the number of support frames is four, and the four support frames are evenly distributed between the wheel rim and the center of the wheel hub.

[0008] Preferably, the bending direction of the support frame is away from the center of the wheel rim.

[0009] Preferably, the center of the wheel hub is offset outward by 5 cm relative to the central axis of the wheel rim.

[0010] Preferably, the outer circumference of the wheel rim is provided with a raised tooth-like structure to adapt to the operating requirements of the rice transplanter.

[0011] The beneficial effects of this utility model are:

[0012] The front wheel of the rice transplanter provided by this utility model has the following advantages compared with the prior art:

[0013] (1) Simplify the structure and reduce costs: The hub center is moved outward relative to the wheel rim center axis directly through the bent support frame, without the need for additional bushings, which reduces the number of parts, simplifies the assembly process, and reduces production and maintenance costs.

[0014] (2) Improve stability and reliability: The support frame, wheel rim, and hub center adopt an integrated molding structure, which has higher structural strength and avoids the problem of front and rear wheel position displacement caused by loose bushings and wear, ensuring the driving stability of the rice transplanter in long-term operation and improving the rice transplanting accuracy.

[0015] (3) Strong adaptability and energy-saving efficiency: The distance of the wheel hub center shift can be set according to the requirements of the rice transplanter model, which can accurately match the position of the rear wheel and ensure that the front and rear wheels are collinear; at the same time, the weight of the front wheel is reduced after the axle sleeve is eliminated, which reduces power consumption and meets the requirements of energy-saving operation.

[0016] (4) Enhanced operational adaptability: The raised tooth structure on the outer circumference of the wheel rim can improve the grip of the front wheel in muddy field ridges, avoid slipping, and enable the rice transplanter to drive stably in complex terrain, adapting to the operational needs of different farmland environments.

[0022] The following are specific embodiments of the present invention described in conjunction with the accompanying drawings, further illustrating the technical solution of the present invention. However, the present invention is not limited to these embodiments. Specific details such as particular configurations and components are provided in the following description merely to aid in a comprehensive understanding of the embodiments of the present invention. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0023] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0024] like Figure 1-2 The diagram shows a front wheel for a rice transplanter provided in this embodiment, comprising a wheel rim 1, a hub center 2, and a support frame 3. The wheel rim 1 has an annular structure with evenly distributed raised tooth-like structures on its outer circumference. This structure enhances the friction between the front wheel and the paddy field surface, preventing slippage during operation. Four support frames 3 are evenly distributed, with one end fixedly connected to the inner wall of the wheel rim 1 and the other end connected to the hub center 2. The support frame 3 is bent in the direction away from the center of the wheel rim 1. This bending structure offsets the central axis of the hub center 2 by 5cm relative to the central axis of the wheel rim 1, thus ensuring that the assembled front wheel and the rear wheel of the rice transplanter remain collinear without the need for additional bushings. The support frame 3, wheel rim 1, and hub center 2 are made of high-strength alloy steel, ensuring the rigidity of the overall structure while reducing the weight of the front wheel, meeting the lightweight operation requirements of the rice transplanter.

[0025] During assembly, the axle of the rice transplanter is passed through the shaft hole of the hub center 2 and fixed. Since the hub center 2 has been preset offset through the bending structure of the support frame 3, the wheel track of the front wheel and the rear wheel can be directly matched. No adjustment is needed to ensure that the front and rear wheels are collinear when driving, which effectively improves assembly efficiency and operational stability.
