Description

Technical Field

[0001] The utility model relates to the technical field of traction equipment, in particular to a traction device for a farmland rotary tiller. Background Art

[0002] In modern agricultural production, rotary tillers are an important type of tilling machinery, which are widely used due to their efficient soil crushing ability and flat surface after tillage. However, with the continuous development of rotary tillers and the diversification of farmland operation needs, the installation and connection problems of rotary tillers and traction devices have gradually become prominent, becoming a key factor restricting the efficiency and operation effect of rotary tillers.

[0003] At present, the installation of rotary tillers and traction devices mainly relies on traditional fasteners such as bolts and pins for connection. This connection method is not only cumbersome to operate and requires professional installation tools and skills, but also easily leads to component damage or loose installation due to improper operation during the installation process. In addition, the adaptability between rotary tillers and traction devices is poor, and different models of rotary tillers require different traction devices, which further increases the difficulty and cost of installation;

[0004] Moreover, the traction device of the rotary tiller often adopts a rigid connection method, such as welding, riveting, etc. This connection method is prone to stress concentration and fatigue damage during operation, resulting in failure of the traction device. At the same time, since the rotary tiller needs to frequently adjust the working angle and depth during operation, the rigid connection method cannot achieve fast and flexible adjustment, which seriously affects the operation efficiency and quality. For this reason, we provide a traction device for the farmland rotary tiller. Utility Model Content
