Problems solved by technology
The blade body of the rotary tillage blade in the prior art is generally a steel plate of equal thickness, and the thickness of the outer arc edge of the blade body is consistent with other parts of the blade body. This type of rotary tillage blade has a simple structure, but when it is installed on a rotary tiller to work, the resistance to entry into the soil is relatively large. Not only increases the power consumption of the rotary tiller, but also easily causes the phenomenon of entanglement of grass and straw

The invention discloses a rotary tillage cutter. The rotary tillage cutter is a spiral and bent bar-shaped plate component composed of a cutter body and a cutter handle. The outer arc side of the cutter body is provided with a cutting edge. The rotary tillage cutter is further characterized in that the cutting edge is provided with sawteeth, the connecting portion between the end portion of the cutter body and the cutting edge is provided with an arc transitional edge. The rotary tillage cutter can obviously reduce the resistance born by the cutter into soil, power consumption of a rotary tiller as well as grass or straw winding, obviously decrease the number of times of manual cleaning and improve the working efficiency.
Description
technical field [0001] The invention relates to a rotary tiller blade on an agricultural rotary tiller. Background technique [0002] At present, the rotary tiller blades used on the existing rotary tillers are generally helically curved elongated plate-shaped members, including a handle and a blade body, and the outer arc edge of the blade body is the working edge. The blade body of the rotary tillage blade in the prior art is generally a steel plate of equal thickness, and the thickness of the outer arc edge of the blade body is consistent with other parts of the blade body. This type of rotary tillage blade has a simple structure, but when it is installed on a rotary tiller to work, the resistance to entry into the soil is relatively large. It not only increases the power consumption of the rotary tiller, but also easily causes the phenomenon of entanglement of grass and straw. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present ...
