Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to all of the drawings, a rotary tiller blade includes:

the tool handle connecting part 1 is of a trapezoidal plate-shaped structure, and a mounting hole 11 is formed in the tool handle connecting part 1;

the rotary cutting part 2 is fixedly connected with one end of the handle connecting part 1, and the rotary cutting part 2 is in a curved surface shape;

the rotary cutting part 2 comprises a knife back 21 and a tangent blade 22, two opposite side edges on the rotary cutting part 2 are respectively set as the knife back 21 and the tangent blade 22, and the thickness of the knife back 21 is greater than that of the tangent blade 22;

the front end face and the rear end face of the tangent blade 22 are both provided with blade grooves 3.

As an embodiment of the present invention, the inner side of the blade groove 3 is provided with a stepped reinforcing rib 31.

As an embodiment of the present invention, a wear-stopping column 32 is provided at one end of the blade groove 3 close to the shank connecting portion 1.

As an embodiment of the present invention, the handle connecting portion 1 and the rotary cutting portion 2 are integrally cast.

As an embodiment of the present invention, the thickness of the blade back 21 is 2 to 4 times the thickness of the front cutting edge 22.

As an embodiment of the present invention, one end of the rotary cutting portion 2 is connected to the handle connecting portion 1, and the other end is connected to the triangular cutting edge 4.

The working principle and the beneficial effects of the technical scheme are as follows: in the rotary tillage process, the blade of rotary tillage blade directly connects with earth and carries out the stripping and slicing, and this also leads to the rotary tillage blade to be the fastest part of loss among the rotary tillage device, and in addition in the rotary tillage process, the intensity and the good also blade's of aggravation wearing and tearing of structural shape of rotary tillage blade. Therefore, the technical scheme provides a rotary cultivator blade, and the main components of the rotary cultivator blade are a handle connecting part 1 used for fixing the whole rotary cultivator blade on a cutter shaft and a rotary cutting part 2 used for carrying out rotary cultivation to cut soil blocks. Two mounting holes 11 are formed in the end portion of the handle connecting portion 1, and a mounting bolt can be used for mounting the blade. The rotary cutting part 2, which is the most important working member, includes a back 21 and a tangential blade 22. The front and rear end faces of the main cutting edge 22 are provided with the cutting grooves 3 to form the cutting edge 22. In order to improve the overall strength of the tangential blade 22 and the rotary cutting part 2, a step reinforcing rib 31 is arranged on the inner side of the blade groove 3 (namely, the upper end of the blade groove 3 in fig. 1 and the end close to the back of the blade), the step reinforcing rib 31 is actually 3-5 transverse edges, the tangential blade 22 cuts soil blocks in the rotary tillage process, and the 3-5 transverse edges can assist in cutting the soil blocks one by one in the cutting process, so that the overall strength and the wear resistance of the blade can be improved to a certain degree, and the rotary tillage blade with the structure can avoid grass winding. In addition, the grinding-stopping column 32 is arranged on the blade groove 3, and the rotary tillage blade also moves forwards when rotating, so the grinding-stopping column 32 is arranged at the tail end of the blade groove 3, and the wear resistance of the blade groove can be further improved. And under the action of the step reinforcing ribs 31 and the grinding stopping columns 32, rotary tillage is more labor-saving.

Synthesize above device structure, the utility model provides a pair of rotary cultivator blade adopts the structure formation tangent blade of seting up the sword groove, combines curved surface form rotary-cut portion and ladder strengthening rib, ends the structure of grinding the post simultaneously, required moment of torsion power when not only can reducing the rotary tillage, but also can improve the abrasion resistance of blade, the whole life of extension.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit of the present invention.
