Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a thresher powered by a lithium battery. Background Art

[0002] my country boasts a vast territory and diverse terrain, with a significant proportion of its land being mountainous and hilly. This is particularly true in the southern regions of China, such as Yunnan, Guangxi, Hunan, and Guizhou, where the steep terrain and limited flat land have led people to adapt to local conditions and develop a unique farming method: terraced fields. Large, modern harvesters often struggle to operate effectively in these rugged terrain and narrow roads. In contrast, threshers, particularly small and portable ones, are more suited to the agricultural needs of these regions. Their compact size and high maneuverability allow them to maneuver easily along narrow field paths or on terraced fields, enabling them to harvest and thresh small plots of land, significantly improving grain harvesting efficiency in mountainous and hilly areas.

[0003] The agricultural thresher with the publication number "CN112567980A" completely relies on the rotational force of the threshing roller to drive subsequent components. Once there is a problem with the roller power, the entire system may be paralyzed. For example, if the roller speed drops due to a fault, it will affect the normal operation of the fan assembly, impeller, etc. Its structure is relatively complex and contains multiple interrelated components, such as fan assemblies, impellers, curved rods, vibrating rods, etc. Failure of any component may affect the overall operation. The complex structure means higher maintenance costs and requires professional knowledge and tools for repair and maintenance. For example, replacing worn parts may require special parts and technicians to operate. In actual applications, if the number of grains is too large or the humidity is high, the screen may still be blocked, which affects the threshing efficiency.

[0004] The agricultural machinery thresher with publication number "CN117044502A" has the following potential defects and deficiencies: Since the thresher contains multiple components such as a chain drive component, a first iron rake, a vibration component, etc., the complexity of the system increases, which may lead to increased maintenance difficulty and reduced reliability. Although the iron rake can help screen out debris from the rice, its efficiency may be limited by the frequency and force of the rake, and it may not be able to effectively remove all impurities, affecting the screening effect of the rice. The complex mechanical structure may increase the difficulty of operation and maintenance, requiring more manual intervention and regular inspections, which will increase the cost of use.

[0005] Terraced fields are usually located in mountainous areas. Because infrastructure construction in these areas is relatively difficult, power supply may be a challenge. Therefore, traditional threshers generally use diesel engines or pedal power. Utility Model Content
