A kind of mowing saw blade
Technical field
The utility model relates to a kind of saw blade, and particularly a kind of mowing saw blade is installed on the mower.
Background technology
The mowing saw blade is installed on the mower, and its structure is the disk of band center hole, around disk several blades or similar blade construction is arranged, and grinds blade in the one or both sides of blade with emery wheel.During work, mowing saw blade high speed rotating constantly cuts off vegetation, reaches the purpose of weeding.The defective of existing mowing saw blade is: during mowing, can carry sandstone, iron wire or the higher object of other similar hardness from the grass secretly, at saw blade during at high speed rotating, these objects can make blade be subjected to great impact, therefore, using easy rust of a period of time at blade, even the possibility tipping, shorten the service life of saw blade and have great danger.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, provides that a kind of scope of application is wide, the efficient mowing saw blade of long service life.
The technical solution adopted in the utility model is: uniform sawtooth on the periphery of metallic matrix, and the center of metallic matrix is provided with centre bore, and alloy cutter head is fixed on the medial surface of sawtooth, is fixing one section blade between three sawtooth in every interval on the periphery of metallic matrix.
The beneficial effects of the utility model are:
1, the utlity model has the wider scope of application, not only can mow, also can be used to cut thicker plants such as shrub, contain at grass under the situation of inclement conditions such as foreign material and also can cut.
2, saw blade can carry out different structural designs according to the difference of cutting object, has improved the service life of saw blade greatly.
3, adopt the sawtooth of blade and welding alloy cutter head to replace the mode of arranging, when cutting harder vegetation, the instant impact that sawtooth contacts with cut material is very big, is easy to object is cut off, and has improved cutting efficiency.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. metallic matrix; 2. centre bore; 3. blade; 4. alloy cutter head; 5. sawtooth.
Embodiment
As Fig. 1,2, be provided with the centre bore 2 of the circle that is used to install at the center of metallic matrix 1, to make metallic matrix 1: uniform sawtooth 5 on the periphery of metallic matrix 1 through the higher steel of heat treated hardness, alloy cutter head 4 fixedly is welded on the medial surface of sawtooth 5, is fixing one section blade 3 between three sawtooth 5 in every interval on the periphery of metallic matrix 1.Like this, alternately being arranged by the blade 3 and the sawtooth of the alloy cutter head 4 of welding around the metallic matrix 1, also is that three sawtooth 5 that weld alloy cutter head 4 are arranged between per two sections blades 3, and the integral rigidity of saw blade significantly improves.In the cutting vegetation, the blade 3 of saw blade alternately contacts with the cut material body with the sawtooth of alloy cutter head 4, has improved cutting effect.
