Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, and in particular to a multifunctional crawler machine. Background Art

[0002] Agricultural crawlers are a special type of crawler designed for the agricultural field. They are widely used in agricultural work and can be used for different agricultural operations, such as land leveling, field operations and harvesting. Traditional agricultural crawlers are generally powered by fuel as the main power source, which not only has the problem of fuel emissions polluting the environment, but also has high fuel costs; directly using motor power to walk or run, the required battery weight is too large, so the extended-range power supply is adopted. The extended-range technology is a technology that charges the battery by adding a generator set to extend the mechanical range. Due to the complexity of cultivated land, agricultural machinery requires a relatively large power drive. For the range extender, a stable high current is required. The existing range extender has a power of 250W / h and an output voltage of 12V, which cannot meet actual needs. Manufacturers need to redesign and reproduce the above problems. The production cost is high, and the products produced are expensive, which farmers cannot afford. Secondly, the adaptability of the crawler machine. The existing crawler machine is prone to rollover or difficulty in climbing when running on rugged terrain, and the function is single. Summary of the invention
