Description

Large-head tillage knife

Technical Field

The utility model relates to a turn over and plough sword technical field, especially relate to a big head of piece sword of turning over.

Background

A method for cultivating soil by using plough to shovel, loosen and turn the upturned soil. Commonly known as plowing, plowing or plowing. The application history in world agriculture is long and the application range is wide. China has begun to use plows with moldboards to plow land more than 2000 years ago. Plowing refers to the process of leveling and loosening the soil by shoveling, scattering, dredging and the like, is the most preliminary process for farmers to cultivate, and can ensure that seeds can breathe and grow easily in the soil. However, the existing tillage knife has structural defects, so that the disturbance coefficient of the existing tillage knife to soil is small when the existing tillage knife is actually used, and the actual tillage effect is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a large-head tillage knife.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a big blade head tilling knife, includes the handle of a knife, the tilling knife connecting hole has been seted up to the outer wall of handle of a knife, insert the bolt in the tilling knife connecting hole, the handle of a knife passes through the bolt-up and connects on rotary cultivator knife rest, the lateral wall integrated into one piece of handle of a knife is equipped with the tilling knife extension, one side integrated into one piece that the handle of a knife was kept away from to the tilling knife extension is equipped with tilling knife tangent portion, one side that tilling knife tangent portion was kept away from the tilling knife extension is provided with tilling knife side-cut portion, one side that tilling knife side-cut portion was kept away from tilling knife tangent portion is provided with the tilling knife kink.

Preferably, the bending angle of the bending part of the tilling blade is one hundred degrees.

Preferably, the right sides of the tangential part and the lateral part of the turning knife are respectively provided with a tangential cutting edge and a lateral cutting edge of the turning knife, and the thicknesses of the cutting edges of the tangential cutting edge and the lateral cutting edge of the turning knife are two millimeters.

Preferably, the cutting edge chamfers of the tangential cutting edge and the side cutting edge of the tilling knife are forty-five degrees.

The utility model provides a big head tilling knife, beneficial effect lies in: through the shape that changes current tilling cutter, set up tilling cutter tangent portion, tilling cutter side cut portion and tilling cutter kink, the bending angle of tilling cutter kink is one hundred degrees, tilling cutter tangent portion, the blade thickness of tilling cutter side cut portion is two millimeters, and tilling cutter tangent portion, the blade chamfer of tilling cutter side cut portion is forty-five degrees, at the tilling cutter tangent portion that uses this tilling cutter, the entering vegetable land that tilling cutter side cut portion can be better, the effectual disturbance coefficient that increases the tilling cutter, vegetable land ditching and ridging problem have been solved, and can make the higher ridge platform of vegetable land play, better tilling effect has.
