Description

Technical Field

[0002] A rice transplanter is an agricultural machine that implants rice seedlings into rice fields. Its main function is to automatically complete rice transplanting in the fields and improve planting efficiency. The travel wheel is one of the important metal components of the rice transplanter. The travel wheel provides power and support, enabling the rice transplanter to move and locate to the required position in the field, ensuring the accuracy and coverage of the operation. At the same time, the travel wheel can provide stable support and balance, helping the rice transplanter to maintain stability in uneven terrain and reduce vibration and shaking.

[0003] The structure of the rice transplanter's walking wheel is quite special. It is not a traditional rubber wheel, but a metal wheel formed by overall welding of various metal accessories. The welding quality of the various accessories of the metal wheel will directly affect the strength of the rice transplanter's walking wheel.

[0004] The existing rice transplanter walking wheels are mostly made by manually positioning each metal accessory one by one, and then welding them in sequence. Although this manual welding processing method can ensure the structural connectivity of the walking wheel, since the metal wheel has more internal struts and the metal accessories are not connected, the method of positioning one by one is adopted. This method greatly increases the workload, and the accuracy of manual positioning and docking with the help of auxiliary tooling needs to be improved; secondly, during the welding process of a complete metal wheel, the assembly and disassembly between the accessories and the auxiliary tooling needs to be carried out many times, the work process is relatively cumbersome, and the work efficiency is low, which in turn affects the welding processing and production progress of the rice transplanter walking wheel, and has a low adaptability to the batch processing and production of the rice transplanter walking wheel.
