AI Technical Summary
Technical Problem
Existing paddy field walking devices have difficulty turning in muddy soil, damage the soil environment, and crush or injure seedlings, and have poor adaptability.
Method used
Adopting a biomimetic design, mimicking the leg movements of a duck, it employs a walking mechanism that utilizes the support structure of mechanical legs, palms, and toes to open and close in mud. Combined with a symmetrical layout and transmission mechanism, it provides a power and steering system to ensure stability and adaptability.
Benefits of technology
It improves stability when walking in muddy soil, reduces soil damage, avoids crushing or damaging seedlings, allows for flexible turning and adaptability to rice planting row spacing, and improves the reliability and efficiency of operations.

Abstract
The invention discloses a bionic walking device for a paddy field, and belongs to the technical field of agricultural machinery. The walking device comprises a rack, a transmission mechanism, a power system and four mechanical legs, the lower portions of the two sides of the rack are each provided with two mechanical legs, and each mechanical leg comprises a leg mechanism and a sole assembly; a power system is arranged on the machine frame and transmits power to the leg mechanisms through a transmission mechanism, and lifting and falling of the leg mechanisms are achieved. The foot sole assembly comprises a supporting palm, a middle toe and two side toes, when the leg mechanism drives the supporting palm to fall, the side toes on the two sides are opened, the contact area with mud soil is increased, and the walking device is prevented from sinking; when the leg mechanism drives the supporting palm to lift up, the side toes on the two sides contract, and the resistance between the foot sole and mud soil is reduced. The problems that a common walking mechanism is large in walking resistance and difficult to turn in the muddy soil environment of the paddy field, the soil environment of the paddy field is damaged, and seedlings are pressed and damaged are solved.
