In order to realize the purpose, the utility model adopts the following technical scheme: comprises a rotating shaft, a rotating shaft and a rotating shaft,

the rotating shaft is provided with a plurality of fixed disks;

the fixed disks are used for fixing the positions of the blades;

the blade edge is at a 45-degree oblique angle.

As a further description of the above technical solution: five fixed disks are fixed on the rotating shaft and are solid disks.

As a further description of the above technical solution: five fixed disks are uniformly distributed on the rotating shaft.

As a further description of the above technical solution: the fixed disc is of a disc-shaped structure.

As a further description of the above technical solution: seven blades are fixed on the fixed disc and are alloy blades.

As a further description of the above technical solution: seven notches are uniformly formed in the fixed disc.

As a further description of the above technical solution: the blade is fixedly arranged at the notch.

As a further description of the above technical solution: the blade is a spiral blade.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment: the device comprises a rotating shaft 1 and a plurality of fixed disks 2, wherein the rotating shaft 1 is provided with the fixed disks 2; the blades 3 and the fixed disks 2 are used for fixing the positions of the blades 3, and the cutting edges of the blades 3 are inclined at an angle of 45 degrees; the spiral blades 3 are uniformly distributed on the outer side of the fixed disc 2, the cutting edges of the blades 3 face outwards, the blades are made of alloy materials, the blades inclined at 45 degrees can cut faster, and the number of the blades 3 can be changed according to the requirements of a trimming field; the equipment can be driven to rotate in various modes, such as direct driving by an engine, driving of a hydraulic pump by the engine and driving of a motor and forward driving by a land wheel of the whole cutting device, and acceleration driving of a gear; when this equipment began to use, the cooperation of the bed knife of highly making spiral blade 3 and fixed setting in the below of adjustable pivot 1 will press close to the grass trunk on ground and also be drawn into inside and prune, and the grassland that makes the pruning out is levelly and smoothly pleasing to the eye more, and the space between blade 3 can make the grass of cutting discharge to outside in the grass box that collects.

Referring to fig. 2, a connecting hole 4 is formed in a transverse surface of one end of the rotating shaft 1; the connecting hole 4 is used for installing and fixing the equipment on other devices; the five solid fixed disks 2 uniformly arranged on the rotating shaft 1 can ensure that the blade 3 can keep the original shape in the using process and is not easy to deform.

Referring to fig. 3, seven spiral blades 3 are uniformly arranged at the notches 5 formed in the fixed disk, and a part of the blades 3 are embedded in the disk-shaped fixed disk 2, so as to achieve better mechanical properties.

The working principle is as follows: when the cylindrical squirrel cage hob consisting of a plurality of strip spiral blades 3 works, the height of the rotating shaft 1 is adjusted to enable the hob to be adjusted to a target height, and when the hob rotates, grass plants to be trimmed are pulled in by matching with a bottom knife fixedly installed below the hob; the bottom cutter and the hob blade 3 form relative movement, and countless open-close double-edged scissors are formed in the rotating process of the hob; when the blade edge of the blade 3 of the hob meets the blade edge of the bottom knife, the grass plants can be cut off just like closed scissors.

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 and the scope of the invention.
