3. blade mount pad, 31, fixed through-hole, 32, mounting hole.
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 shaft comprises:
the cutter shaft comprises a cutter shaft body 1 and a cylindrical rod-shaped structure, wherein connecting discs 2 are arranged at two ends of the cutter shaft body 1;
the cutter shaft comprises blade mounting seats 3, wherein at least one blade mounting seat 3 is sleeved on the outer peripheral surface of the cutter shaft body 1, and all the blade mounting seats 3 are fixed on the cutter shaft body 1 in a clockwise spiral arrangement mode.
The blade mounting seat 3 is of a plate-shaped structure, a through hole 31 for connecting and fixing the blade mounting seat with the cutter shaft body 1 is formed in the middle of the blade mounting seat, and one side face of the blade mounting seat 3 is a curved surface.
As an embodiment of the present invention, the blade mounting base 3 is further provided with a mounting hole 32 for mounting a rotary blade.
As an embodiment of the present invention, the rotation angle between two adjacent blade mounting seats 3 is 54 degrees.
As an embodiment of the present invention, the connection pad 2 is further provided with a positioning notch 21.
As an embodiment of the present invention, the included angle between the central lines of the two opposite side edges on the blade mounting base 3 is 153 degrees.
The working principle and the beneficial effects of the technical scheme are as follows: the rotary tiller shaft mainly has the function that the rotary tiller shaft rotates around the central axis of the rotary tiller shaft under the driving of a power device of a tractor, and the rotary tiller shaft rotates along with the rotary tiller shaft in the rotating process of the rotary tiller shaft and digs soil in a field. The common rotary tiller shaft is easy to be wound by weeds in fields in the soil planing process to influence the soil planing effect, and the rotary tiller shaft disclosed by the technical scheme is designed for this reason. The foundation structure of the rotary tiller cutter shaft comprises a cutter shaft body 1 serving as a rotary main shaft and a plurality of blade mounting seats 3, wherein the blade mounting seats 3 are spirally arranged in a clockwise 54-degree mode (namely, the included angle of the same radial axis on every two adjacent blade mounting seats 3 is 54 degrees) by combining the length of the cutter shaft body 1, the length of a rotary blade and the length of field weeds. The blade mount 3 is a fan-shaped plate-like structure, and the fan-shaped width is 153 degrees.
Synthesize above device structure, the utility model provides a pair of rotary cultivator cutter shaft adopts rationalization structural design, and is not only laborsaving when carrying out the rotary tillage to the field, and it is effectual to dig soil moreover, is difficult for twining the grass, and the soil block after the rotary tillage is even.
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.
