Grassland hardening loosening machine described in bright patent CN200810166842, its cutter for being used be before three in after the draw point wheel that arranges,
By driving draw point wheel to roll and in addition axial counterweight is pressed into each draw point in soil, plate function is solved so as to realize loosening the soil, so
And, inventor find the cutter of this kind of form due to being before in after longitudinal direction arrangement, and laterally span is narrower, can cause whole machine
Operating efficiency step-down, and cantilevered draw point due to length it is excessive compared to ratio for knife footpath, easily cause the firm of draw point
Degree is reduced, when running into the stone or hard soil block that are imbedded under earth's surface once draw point in the solution plate operation process that loosens the soil, it is easy to
Cause draw point bending even to rupture, have a strong impact on cutting-tool's used life, and then the economic benefit of the solution trigger that affects to loosen the soil, to herding
The people cause certain economic loss.Therefore, a kind of rational in infrastructure, efficiency and rigidity is high, the grassland of long service life is loosened the soil solution plate
Rounding machine cutter is urgently released.
