Drawings

The invention will be further described with reference to the following figures and examples:

FIG. 1 is a schematic plan view of a blade;

FIG. 2 is a side view of the blade;

FIG. 3 is a plan view of the cutter;

fig. 4 is a side view of the tool.

Detailed Description

As shown in fig. 1 to 4, the present invention discloses a working tool for a field management machine, which comprises a plurality of blades 1 (generally three) arranged along a circumferential direction and a tool shaft 3 for mounting the blades 1, wherein the blades 1 are provided with a movable cutting section 1011 on one side facing a rotation direction, and the movable cutting section 1011 can actively cut weeds towards the rotation direction when the tool is driven to rotate, so as to realize high-efficiency weeding and backfill; the direction facing to the rotation direction refers to the side of the blade which is forward in the rotation direction when the cutter is driven to rotate, and the movable cutting section can directly act on weeds and finish cutting.

In this embodiment, the movable cutting section 1011 forms a cutting edge, which can cut weeds in a targeted manner, so that the weeds can be cut up more easily.

In this embodiment, the blade 1 includes a mounting portion 102 and a working portion 101, the mounting portion 102 is used for mounting the blade on the tool shaft 3, and the movable cutting section 101 is located in the working portion.

In this embodiment, the working tool further includes a grass blocking member 2 fixedly disposed on the garden management machine, and the grass blocking member 2 can be fixed in any conventional mechanical fixing manner capable of being fixedly mounted on the garden management machine, which is not described herein again; the grass blocking part 2 is provided with a static cutting section 201 facing the dynamic cutting section, the dynamic cutting section 101 and the static cutting section 201 form scissors type matching, and the scissors type matching means that two cutting edges similar to scissors between the dynamic cutting section and the static cutting section perform relative opening and closing movement to finish cutting, so that the cutting efficiency is further improved; the grass blocking member 2 is generally a plate-shaped structure, and a static cutting section is formed on one side edge of the plate-shaped structure and corresponds to a movable cutting section on the blade to form a scissor-type fit.

In this embodiment, quiet cutting section 201 forms the blade, cooperatees with the blade on the dynamic cutting section 101, and the more quick cutting is weeds.

In this embodiment, the rotation plane of the working tool when in use faces the advancing direction of the field management machine, and the grass blocking member is arranged on the front side of the working tool; as shown in the figure, the forward direction of the rotation plane is that the cutter rotates transversely and forms a certain inclination angle with the vertical surface, the traveling mechanism and the machine body of the field management machine positioned at the front part of the cutter are pressed on the bottom surface at grass, and the cutter rotating transversely is more beneficial to cutting off weeds and improving the working efficiency.

In this embodiment, blade 1 is at least protruding forward in the position of moving cutting section 1011, as shown in fig. 2, moves cutting section 1011 (whole work portion all is protruding forward in fact, and is easy to assemble, make) and is protruding forward for the installation department, and during the use, fender grass piece sets up in the front side of work cutter, and the protruding cutting section 1011 that moves forward does benefit to and keeps off the cooperation of grass piece and forms scissors structure, accomplishes the work of cutting weeds better.

In this embodiment, the tail end of the working portion 101 is formed with a blade tail 1012 curved backward in an arc shape, the curve is a spiral curve that forms a forward component force to the working blade after the blade tail cuts into the soil, and since the rotation plane of the blade faces the forward direction, the tail end of the blade forms a spiral curve part and forms a forward component force (thrust) after cutting into the soil, thereby improving the forward efficiency and having the effects of energy saving and consumption reduction.

In this embodiment, a cutting edge is formed in the full length of one side of the working part 101 facing the rotation direction, the movable cutting section 1011 extends to the tail of the cutter and is an arc shape facing away from the rotation direction, the cutting edge is formed in the full length, weeds can be cut in the full length range, the matching length between the movable cutting section and the static cutting section can be prolonged by the arc structure, and the working efficiency of cutting the weeds is ensured; by counter-rotating direction is meant that the cutting edges extend radially outwards gradually in the opposite direction to the direction of rotation.

Use the rural area supervisor to adopt around this paper the utility model discloses a walking direction of cutter at the in-process of mowing is the standard, no longer gives unnecessary details here.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
