The utility model is achieved through the following technical solutions：
A kind of open-cell light-type grass-winding proof rotary blade, includes cutter shaft, is distributed on the cutter shaft and arranges in double helix
Arc tool apron, it is characterised in that：The rotary blade with certain bending angle, the rotary tillage are separately installed on the arc tool apron
Knife includes knife handle, the knife handle and arc tool apron snap fit, and mounting hole is respectively equipped at its corresponding matching, the knife handle
Front end be equipped with blade, be successively arranged side cutting edge, transitional edges, main cutting edge and point of a knife part, and lateral incision on the blade
It cuts and multiple spaced circular holes is distributed on the blade above sword.
The rotary blade bending angle is 135 °, and it is 30mm that it, which bends transition radius of curvature,.
The knife handle, which is bolted, is installed on arc tool apron, and the interior arc radius of the arc tool apron is 160mm, outside
Arc radius is 460mm.
The blade shape is arc shaped and uses two-sided sharpening, and knife thickness is gradually thinned from arc knife handle to point of a knife, sword
Mouth thickness is thinned to 2mm by 4mm, and the basil is decreased to 6 ° by 20 °；Point of a knife is set as polygonal shape.
The side cutting edge cutting edge thickness is thinned to 2mm by 4mm, and the basil is decreased to 16 ° by 20 °；Transitional edges width of edge
Degree is 2mm, and the basil is decreased to 8 ° by 16 °；Main cutting edge cutting edge is decreased to 6 ° by 8 ° with a thickness of 2mm, the basil.
The circular hole is on the equiangularly spaced blade being distributed in above the cutting edge of side.
The Circularhole diameter is 8-12mm, and chamfering is provided at bore edges, chamfer radius 0.5-2mm.
The utility model has the advantages that：
(1) the utility model uses the method in the aperture of blade back, mitigates rotary blade self weight and entire rotor weight, can
To reduce power consumption, cost is reduced.
(2) the utility model subtracts twister by frictional force of the soil to tool apron using arc knife handle and arc tool apron
It is small, it is detached from tool apron along circular arc direction, efficiently and effectively reduces the generation of wrapping phenomena in operation, antiwind excellent,
Operation quality is substantially increased, cost is reduced, improves farming efficiency.
Detailed description of the invention：

Specific embodiment：
Referring to attached drawing.
A kind of open-cell light-type grass-winding proof rotary blade, includes cutter shaft 1, is distributed on the cutter shaft 1 and arranges in double helix
The arc tool apron 2 of column, it is characterised in that：The rotary blade with certain bending angle is separately installed on the arc tool apron 2, it is described
Rotary blade includes knife handle 11, the knife handle 11 and 2 snap fit of arc tool apron, and is respectively equipped with mounting hole at its corresponding matching
3, the front end of the knife handle 11 is equipped with blade 6, be successively arranged on the blade 6 side cutting edge 7, transitional edges 8, main cutting edge 9 with
And 10 part of point of a knife, and there are five spaced circular holes 4 for distribution on the blade of 7 top of side cutting edge.
The rotary blade bending angle is 135 °, and it is 30mm that it, which bends transition radius of curvature,.
