Abstract
The utility model discloses a cutting knife for a brush cutter. The cutting knife for the brush cutter comprises a cutting board, a plurality of blades distributed on the periphery of the cutting board and adjusting mechanisms used for respectively adjusting each of the blades, wherein a connecting hole is formed in the center of the cutting board; cutting edges are arranged at one ends of the blades; each adjusting mechanism comprises a mounting shaft, a nut and a spring; the mounting shafts pass through the mounting holes of the blades and the mounting hole of the cutting board in turn and then are in threaded connection with the nuts; the springs are sleeved on the mounting shafts; one ends of the springs are resisted against the blades while the other ends are resisted against the nuts. When the blade part of the cutting knife provided by the utility model is not used, the blade part can be rotated to the interior, so that a user can be prevented from being carelessly hurt; during a working process, when the cutting edges meet hard objects, such as stone, the blades are difficult to break because the blades have certain elasticity, and the service life is longer; when the blades are damaged, the blade part can be exchanged ,and the whole cutting knife need not be exchanged; the exchange operation is convenient; unnecessary waste is avoided; the working efficiency is increased.
Description
Technical field
The utility model belongs to graden machine equipment, is specifically related to a kind of cutter of brush saw.
Background technology
At present, brush saw is used for cutting off shrub, 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 when work, when blade is encountered the hard objects such as stone, the blade of integral type does not have elasticity, easily causes blade to burst apart and need to change cutter, make the service life of cutter short, affect operating efficiency.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of long service life, blade are difficult for injuring user brush saw cutter when changing conveniently and depositing.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of cutter of brush saw, it comprises knife plate, multiple guiding mechanism that is evenly distributed on the blade on knife plate circumference and is respectively used to regulate each blade, the center of knife plate offers connecting hole, one end of blade is provided with blade, guiding mechanism comprises installation shaft, nut and spring, installation shaft is successively through being connected with nut thread after the installing hole of blade and the installing hole of knife plate, spring housing is contained in installation shaft, one end is against blade, and the other end is against nut.
Wherein, on knife plate, near connection hole, offer locating hole.
Wherein, on knife plate, evenly offer multiple through holes.
Wherein, on blade, the one end with respect to blade is provided with rubber sleeve.
Wherein, on nut, with respect to the one end against spring, be provided with sphere.
(3) beneficial effect
Compared with prior art, the blade section of the utility model cutter can be threaded to inside when not using, and avoids injuring user because of carelessness, and on blade, is provided with rubber sleeve, avoids scratching user when operation.
Accompanying drawing explanation
Fig. 1 is the structural representation in cutter when work of the utility model brush saw.
Fig. 2 is the structural representation of the cutter of the utility model brush saw while not working.
Fig. 3 is the cross-sectional view in cutter when work of the utility model brush saw.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of the cutter of the utility model brush saw as depicted in figs. 1 and 2, its cross-section structure as shown in Figure 3, the cutter of this brush saw comprises knife plate 1, multiplely be evenly distributed on the blade 2 on knife plate 1 circumference and be respectively used to regulate the guiding mechanism of each blade 2, the center of knife plate 1 offers connecting hole 11, one end of blade 2 is provided with blade 21, guiding mechanism comprises installation shaft 3, nut 4 and spring 5, installation shaft 3 is successively through being threaded with nut 4 after the installing hole of blade 2 and the installing hole of knife plate 1, spring 5 is sleeved in installation shaft 3, one end is against blade 2, the other end is against nut 4.
On knife plate 1, near connecting hole 11 places, offer locating hole 12; In the present embodiment, the quantity of locating hole 12 is 2, is evenly distributed on connecting hole 11 around.The setting of locating hole can avoid knife plate 1 to occur the phenomenon of skidding.
On knife plate 1, evenly offer multiple through holes 13, the not of uniform size of multiple through holes 13 causes, and the setting of through hole can alleviate the weight of cutter.
On blade 2, with respect to one end of blade 21, rubber sleeve 6 is installed, when blade is retracted, avoids scratching user.
On nut 4, with respect to being provided with sphere 41 against one end of spring 5, while making push nut, avoid injuring user.
When finishing the work, only need the sphere portion of push nut, overcome spring force and drive installation shaft down to move, make the head of installation shaft and knife plate reserve enough gaps before, promote again rubber sleeve and blade is completed to the below that pushes knife plate, avoid injuring because of carelessness user; When blade is encountered the hard objects such as stone in work, because blade has certain elasticity, be difficult for causing and break, longer service life; And during breaks down, only need to change blade section, do not need whole cutter to change, it is convenient to change, and reduces unnecessary waste, increases work efficiency.
These are only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
