The invention discloses an earthworm-imitating corrugation lubrication body surface anti-drag subsoiler which is composed of a shovel handle and a shovel blade. The shovel blade is fixedly arranged at the lower end of the shovel handle through a bolt group, and the shovel handle is provided with a first corrugation non-smooth structure and a second corrugation non-smooth structure. The corrugation lubrication function surface is designed based on the biological surface structure, biological lubrication and coupling bionic theory. When the earthworm-imitating corrugation lubrication body surface anti-drag subsoiler is used, a lubricant is conveyed to the positions of a plurality of lubricant spray holes through thin pipes and lubricant conveying holes and sprayed to the shovel blade, the blade surface of the shovel blade has a non-smooth surface to have a lubricating effect, and binary coupling bionics is achieved. The first corrugation non-smooth structure and the second corrugation non-smooth structure reduce soil adhesion. The earthworm-imitating corrugation lubrication body surface anti-drag subsoiler is simple in structure, safe, reliable, convenient to dismantle and high in working efficiency, has a small lubricating medium demanded quantity, reduces cost, is low in maintenance cost and small in resistance during work, effectively reduces soil adhesion, improves service life and is suitable for being widely applied.
Description
technical field [0001] The invention relates to an agricultural tool, in particular to a drag-reducing deep loosening shovel imitating earthworm corrugated lubricating body surface. Background technique [0002] The role of subsoiling is to break the plow bottom layer, deepen the plow layer, improve the soil structure, improve the ability of soil water storage and moisture conservation and the utilization rate of soil fertilizer without plowing the soil. The subsoiling shovel is an important agricultural method used in conservation tillage. Machine tools also represent the level of subsoiling technology. [0003] The adhesion and resistance of the soil to the surface of the subsoiler shovel seriously affect the working efficiency, service life and operation quality of the machine tools, and increase energy consumption and aggravate the energy and environmental crisis. The resistance of subsoiler shovel components includes the following three parts: 1. The resistance caused ...
