Abstract

The utility model relates to a kind of brush saw cutter and applies the brush saw of this cutter, and during its work, rotating shaft is not easily stuck.Described brush saw cutter comprises: knife plate, be multiplely evenly distributed on knife plate movable blades circumferentially, the upper surface of knife plate is distributed with multiple gear piece around central installing hole surrounding, the knife plate of High Rotation Speed drives each gear piece to cut the weeds of the rotating shaft of contiguous knife plate central authorities or line etc., avoid rotating shaft to be wound, guarantee normal work.During work, the knife plate of High Rotation Speed drives each gear piece to cut the weeds of the rotating shaft of contiguous knife plate central authorities or line etc., avoids rotating shaft to be wound, guarantees normal work.Simultaneously knife plate drives each movable blades, makes it do at centrifugal force, outwards launches and whose knife plate High Rotation Speed, to cut weeds etc.

Description

Brush saw cutter and apply the brush saw of this cutter
Technical field
The utility model relates to a kind of brush saw cutter and applies the brush saw of this cutter.
Background technology
At present, brush saw is used for cuts brush, weeds, prunes, cuts down undersized log, cuts bamboo, repairs lawn etc., the cutter of existing brush saw adopts the blade of integral type, and its shortcoming is when not using, and blade exposes and easily injures user, and during work, when blade encounters the hard objects such as stone, the blade of integral type does not have elasticity, easily causes blade to burst apart and needs to change cutter, make the service life of cutter short, affect operating efficiency.
For this reason, there is a kind of cutter of brush saw in prior art, it comprises knife plate, is multiplely evenly distributed on knife plate movable blades circumferentially, a rotating shaft in knife plate central authorities, being in transmission connection for the driving mechanism driving knife plate to rotate on rotating shaft and handle; Its in use, the foreign material such as weeds or line, the rotating shaft be easily wrapped in make rotating shaft stuck, and then cause working.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of brush saw cutter and applies the brush saw of this cutter, and during its work, rotating shaft is not easily stuck.
In order to solve the problems of the technologies described above, the utility model provides a kind of brush saw cutter and comprises: knife plate, be multiplely evenly distributed on knife plate movable blades circumferentially, the upper surface of knife plate is distributed with multiple gear piece around central installing hole surrounding, the knife plate of High Rotation Speed drives each gear piece to cut the weeds of the rotating shaft of contiguous knife plate central authorities or line etc., avoid rotating shaft to be wound, guarantee normal work.
Each gear piece is substantially triangular in shape, and the top hypotenuse of gear piece is distributed with sawtooth; The angle of the top hypotenuse of each gear piece and the upper surface of knife plate is acute angle, to guarantee effect and the efficiency of the cutting work of gear piece.
Preferred scheme is conveniently installed further, described knife plate is distributed with the bar hole matched with each gear piece.
In order to reduced volume, described knife plate entirety is triangular in shape, and each end angle of knife plate has been bolted movable blades.
Described knife plate comprises upper and lower symmetry and refers to the upper and lower knife plate of setting, and each movable blades is located between upper and lower knife plate by bolt.When not using, each blade can be received in each limit of knife plate, and then reduce overall volume, be convenient for carrying.
The front and back end of each gear piece is respectively equipped with the spacing preiection extended laterally, the upper and lower hypotenuse of gear piece is engaged in the laterally zygomorphic bar hole of upper and lower knife plate respectively, spacing preiection is in outside corresponding bar hole, to play position-limiting action, prevent when knife plate High Rotation Speed, gear piece comes off and produces security incident.
A kind of brush saw, it comprises: above-mentioned brush saw cutter.
Technique scheme of the present utility model has the following advantages compared to existing technology: during brush saw cutter work of the present utility model, the knife plate of High Rotation Speed drives each gear piece to cut the weeds of the rotating shaft of contiguous knife plate central authorities or line etc., avoid rotating shaft to be wound, guarantee normal work.Simultaneously knife plate drives each movable blades, makes it do at centrifugal force, outwards launches and whose knife plate High Rotation Speed, to cut weeds etc.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below basis specific embodiment and by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is the vertical view of the using state of brush saw cutter of the present utility model;
Fig. 2 is the stereogram of described brush saw cutter;
Fig. 3 is the vertical view of the collapsed state of described brush saw cutter;
Fig. 4 is the side view of Fig. 3;
Fig. 5 is the exploded view of described brush saw cutter;
Fig. 6 is the structural representation of gear piece.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail:
See Fig. 1-5, a kind of brush saw cutter, comprise: knife plate 1, three is evenly distributed on knife plate movable blades 5 circumferentially, the upper surface of knife plate 1 is distributed with multiple gear piece 3 around central installing hole surrounding, the knife plate 1 of High Rotation Speed drives each gear piece 4 to cut the weeds of the rotating shaft of contiguous knife plate central authorities or line etc., avoid rotating shaft to be wound, guarantee normal work.
Each gear piece 3 is substantially triangular in shape, and the top hypotenuse of gear piece 3 is distributed with sawtooth 3-1; The angle of the top hypotenuse of each gear piece 3 and the upper surface of knife plate 1 is acute angle, to guarantee effect and the efficiency of the cutting work of gear piece.
In order to reduced volume, described knife plate 1 is overall triangular in shape, and as Fig. 1, preferred scheme is further, three limits depression in circular arc type to the inside of knife plate 1.
Described knife plate 1 comprises symmetrical up and down and refers to the upper knife plate 1-1 of setting, lower knife plate 1-2, and each movable blades 5 is located on each end angle between upper and lower knife plate by bolt 7.When not using, each blade 5 can be received to each limit between upper and lower knife plate, and then reduce overall volume, be convenient for carrying.
The front and back end of each gear piece 3 is respectively equipped with the spacing preiection 4 extended laterally, the upper and lower hypotenuse of gear piece 3 is engaged in the laterally zygomorphic bar hole of upper and lower knife plate respectively, spacing preiection 4 is in outside corresponding bar hole, to play position-limiting action, prevent when knife plate High Rotation Speed, gear piece comes off and produces security incident.
A kind of brush saw, it adopts above-mentioned cutter, can avoid driving the windings such as the rotating shaft of knife plate 1 is grown grass, line, guarantees normal work.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And these belong to spirit institute's apparent change of extending out of the present utility model or change and are still among protection domain of the present utility model.
