Description

Highly flexible walking wheel auxiliary components and driverless lawn mowers

Technical field

The present invention relates to the technical field of unmanned lawn mower equipment, specifically to a high-flexibility walking wheel auxiliary assembly and an unmanned lawn mower.

Background technique

A lawnmower is also called a lawnmower, a lawnmower, a lawn trimmer, etc.; a lawnmower is a mechanical tool used for trimming lawns, vegetation, etc. It consists of a cutterhead, engine, running wheels, traveling mechanism, blades, It consists of handrails and control parts.

As for the walking wheel of the drone, it is a component that supports the movement of the unmanned lawn mower and plays an important role in the driving of the drone.

Under the current technology, when an unmanned lawn mower is mowing, its running wheels are mostly driven on muddy roads. During this process, the soil and impurities on the ground will adhere to the surface of the running wheels, causing long-term damage. When working for a long time, it will affect the normal operation of the running wheel, and thus affect the working progress of the lawn mower. The solution under the existing technology is usually to simply set a scraper on the side of the running wheel, and use the scraper to clean the surface of the running wheel. To remove the soil, the scraper is generally fastened with bolts, and the scraper is in slight contact with the running wheel or is set at a certain distance. In actual work, on the one hand, its fixation is prone to loosening, and the connection stability is not high. When partial damage occurs, the scraper needs to be replaced as a whole, which is cumbersome to operate and cannot well meet actual use needs; on the other hand, the scraper may cause scratch damage to the running wheels under long-term operation, and the scraper may The plate will also be worn, creating a gap between it and the running wheel, which will have a negative impact on its soil removal effect. Furthermore, when the running wheel travels too fast, the soil and debris on it will be thrown up, which may then stick to it. Attached to the fuselage, it will cause pollution to the lawn mower, and may even enter the fuselage, affecting the work of the internal devices of the fuselage. It has low applicability to the running wheels and accessories of unmanned lawn mowers under the existing technology. , cannot meet actual work needs, thus affecting the overall economic benefits of lawn mowing work.

To this end, the present invention proposes a highly flexible walking wheel auxiliary assembly and an unmanned lawn mower to solve the above problems.
