Description

Blade for brush cutter

Technical Field

The utility model belongs to the technical field of the brush cutter, concretely relates to brush cutter blade.

Background

The brush cutter is mainly used for cleaning small-diameter plants such as shrubs and the like, and has higher requirements on blades compared with a mower. Because the bush is harder, the blade wearing and tearing condition often appears, and traditional saw bit structure change can only be changed as a whole, meets hard thing such as stone when the saw bit rotates at a high speed moreover, and the sawtooth easily bursts apart the spill, takes place danger.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cutter blade for a brush cutter, which is of a split type blade structure, and the cutter blade is easier to replace after being worn; the sawtooth-shaped cutting edges are concentrated on the cutter head, so that the cutter head is not easy to break, and the potential safety hazard is reduced.

The purpose of the utility model is realized like this: the utility model provides a brush cutter blade, includes the bottom plate, and the bottom plate middle part sets up the shaft hole of cooperation brush cutter, and bottom plate both ends demountable installation has the tool bit, the head of tool bit is triangle-shaped, and two sides of head are formed with the zigzag blade.

Furthermore, the two sides of the bottom plate are provided with straight cutting edges which are butted with the saw-tooth-shaped cutting edges.

Furthermore, the cutter head is made of alloy materials, and the strength of the cutter head is greater than that of the bottom plate.

Furthermore, the tail part of the cutter head is fixedly connected with the bottom plate through two screws.

Furthermore, the specific shape of the sawtooth-shaped cutting edge is as follows, the side edge of the head part of the tool bit is an inclined cutting surface, and sawteeth are arranged on the cutting surface.

Compared with the prior art, the utility model outstanding and profitable technological effect is:

1. the cutter head and the bottom plate are assembled in a split way, and the cutter head is convenient to replace after being worn;

2. the sawtooth-shaped cutting edges are concentrated on the cutter head, so that the distribution can be finer and the cutter head is not easy to break;

3. the head of tool bit is triangle-shaped, and structural strength is good, and one side wearing and tearing back overturns, and the opposite side can continue to use long service life.

Reference numerals: 1. a base plate; 1a, a shaft hole; 1b, a straight cutting edge; 2. a cutter head; 2a, a sawtooth-shaped cutting edge; 3. a screw; 4. and a nut.

Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

A blade for a brush cutter combines a drawing 1 and a drawing 2, and comprises a bottom plate 1, wherein the middle part of the bottom plate 1 is provided with a shaft hole 1a matched with the brush cutter so as to drive the bottom plate 1 to rotate at a high speed. Two ends of the bottom plate 1 are provided with a cutter head 2 through two screws 3; the head of the tool bit 2 is triangular, inclined cutting surfaces are arranged on two sides of the head exposed out of the bottom plate 1, saw teeth are arranged on the cutting surfaces to form saw-tooth-shaped cutting edges 2a, and the saw-tooth-shaped cutting edges 2a on two sides of the tool bit 2 are symmetrically arranged.

Wherein, the two sides of the bottom plate 1 are provided with straight cutting edges 1b which are butted with the sawtooth-shaped cutting edges 2 a. The sawtooth-shaped cutting edge 2a is used for cutting harder shrubs, and the flat cutting edge 1b is used for cutting softer shrubs, so that the cooperation of the sawtooth-shaped cutting edge and the flat cutting edge can realize more efficient operation.

Wherein, tool bit 2 is alloy material, and intensity is greater than bottom plate 1 to guarantee tool bit 2's durability.

Specifically, referring to fig. 2, mounting holes are formed in the tail of the tool bit 2 and two ends of the bottom plate 1, and the screw 3 penetrates through the mounting holes and then is matched with the nut 4 below the bottom plate 1, so that the tool bit 2 and the bottom plate 1 can be detachably mounted.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
