[0002] Existing rice transplanter walking systems require multiple sets of linkages to control the transplanter's forward, backward, and neutral movement. This complex structure makes the linkages prone to damage after prolonged use, leading to safety hazards such as machine stalling. Secondly, the mechanical gear shifting requires significant operating force, causing driver fatigue after extended periods and reducing human-machine comfort. Furthermore, the diverse types of linkages in existing rice transplanter walking systems require precise adjustments, placing high demands on factory setup personnel and after-sales maintenance staff, resulting in low efficiency and poor convenience.

[0003] In summary, the current transmission and walking systems of rice transplanters use mechanical linkage mechanisms, which have a low degree of automation, poor sensitivity, and low efficiency. There is a lack of transmission and walking systems with high sensitivity and high efficiency that are suitable for rice transplanters. Summary of the Invention

A fixing seat (53) is provided on the first connecting plate (51) and the second connecting plate (52). The first tooth plate angle sensor (22) is fixed on the fixing seat (53) and is used to collect the rotation direction of the first tooth plate (214) and the angle of rotation in that direction.

6. The transmission and walking system suitable for a rice transplanter according to claim 5, characterized in that, The mounting base (53) is also equipped with a third connecting plate (54), which is fixed to the steering column (5).

7. The transmission and walking system suitable for a rice transplanter according to claim 6, characterized in that, The bottom end of the steering column (5) is provided with a fourth connecting plate (55), and the end of the fourth connecting plate (55) is provided with a mounting base (56). The housing of the motor (231) is fixed on the mounting base (56).

8. The transmission and walking system for a rice transplanter according to claim 7, characterized in that, The second toothed plate (232) has a fixed shaft in the center, and the second toothed plate (232) is movably sleeved on the fixed shaft.

9. The transmission and walking system for a rice transplanter according to claim 8, characterized in that, It also includes a second toothed plate rotation detection mechanism, which includes a second toothed plate angle sensor (7).
