Description

Technical Field

[0001] The utility model relates to the technical field of soil leveling devices, in particular to a soil leveling device for a rotary tiller. Background Art

[0002] Driven soil tillage machinery with rotating blades as working parts, also known as rotary tillers, are divided into two types: horizontal axis type and vertical axis type according to the configuration of the rotary tiller blade shaft. Horizontal axis rotary tillers with horizontal blade shaft are more commonly used and have stronger soil crushing ability, which is beneficial to saving farming time, improving work efficiency, and making full use of the tractor's power.

[0003] After the existing rotary tillers till the soil, they must be equipped with corresponding leveling devices to flatten the turned-up soil to make it flat. However, the existing leveling devices have the following defects when used: the leveling devices are generally equipped with a long strip-like plate to move and spread the soil. However, in many cases, due to the slow flattening and accumulation, more soil is accumulated, resulting in greater resistance, and the height is difficult to adjust, which affects the use effect.
