Description

Technical Field

[0001] The utility model belongs to the technical field of land cultivation, and in particular relates to a soil-preventing rotary tillage shield for agricultural machinery. Background Art

[0002] A rotary tiller currently consists of a series of key components: a suspension frame, gearbox, housing, chain, drag plate, cutter roller, lower tie rod, universal joint, and upper tie rod. During operation, the tractor moves forward, simultaneously sending power to the power output shaft. This power is then transferred through the universal joint shaft and gearbox, driving the cutter roller to rotate. Because the cutter roller rotates faster than the tractor's forward speed, the blade's tip (cutting edge) forms a curved path across the ground, cutting the soil from top to bottom and throwing the resulting soil clumps backward. These clumps impact the housing and drag plate, breaking them up further and falling back to the ground, where they are leveled by the drag plate. As the unit advances, the blades continuously cut and break up the soil. However, when the soil surface is moist, some of the thrown soil clumps may adhere to the housing plate. As these clumps accumulate and become contaminated by roots and other pollutants, they can easily clog the housing plate, preventing the cutter roller from properly operating. Utility Model Content
