Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in FIG. 1 to 3, a kind of with protecting cover cutter for mower, including home position are provided with installation through-hole 11
Projection shape cutterhead 1, saw blade 2, home position are provided with the cylindrical shape protective cover 3 of through hole 34, and the protective cover 3 is by the same pericardium of cutterhead 1
It is rolled in inside, the bottom surface outer rim of cutterhead 1 is laid with several cutter grooves 12, the saw blade 2 is equilateral triangle and three angles are
Mowing pointed tooth 21, circle center line connecting of the saw blade 2 provided with three fixing holes 22 and three fixing holes 22 is described into equilateral triangle
Saw blade 2 is coupled by screw 7 through any two in three fixing holes 22 with the screwed hole 6 in cutter groove 12, when cutting for saw blade 2
Careless pointed tooth 21 is damaged, and saw blade 2 can be rotated to 60 degree and install fixation using corresponding two fixing holes 22, the mowing point renewed
Tooth 21 protrudes work, convenient and economical and practical, improves circumference uniform distribution on service life, the top surface of the cutterhead 1 and is provided with several
The first ball 5 is provided with first hemispherical-shaped aperture 13 and the first hemispherical-shaped aperture 13, the outer wall circumference uniform distribution of the column body of cutterhead 1 is set
Have in several second hemispherical-shaped apertures 14 and the second hemispherical-shaped aperture 14 and be provided with the second ball 4, the protective cover 3 includes ring flat-plate 31,
On the bottom surface of ring flat-plate 31 from outside to inside successively with one heart be provided with the first cylinder 32 and the second cylinder 33, the bottom surface of the ring flat-plate 31 with
First ball 5 is tangent, and the inwall of second cylinder 33 and the second ball 4 are tangent, and the first ball 5 is used for supporting the weight of protective cover
Power so that supported between protective cover 3 and cutterhead 1 for rolling friction, the second ball 4 is used for limiting support protective cover, makes it will not
Radial-play causes protective action to fail, so when 1 rotary work of cutterhead, 3 meetings of protective cover are trickle to be swung without rotating,
Effectively stop the splash that the cutterhead 1 and saw blade 2 of rotation at a high speed are got, with very strong protective action.
Coordinate between the ball 5 of first hemispherical-shaped aperture 13 and first for gap, second hemispherical-shaped aperture 14 and second
Coordinate between ball 4 for gap, the first ball 5 can be rolled in the first hemispherical-shaped aperture 13, and force of rolling friction is small, the second ball 4
Rolled in the second hemispherical-shaped aperture 14, force of rolling friction is small so that cutterhead 1 will not drive protective cover 3 to rotate when rotating, protective cover
3 meetings are trickle to be swung, and can play a part of effectively stopping splash.
There is gap between the bottom surface of second cylinder 33 and the convex shoulder plane of cutterhead 1 so that protective cover 3 is not contacted with cutterhead 1,
The rotation of cutterhead 1 is avoided to drive protective cover 3 to rotate.
The diameter of the through hole 34 is more than the diameter of installation through-hole 11, facilitates motor reel to extend through through hole 34 logical with installing
Hole 11 couples.
The bottom surface of first cylinder 32 is less than the bottom surface of saw blade 2, and cutterhead 1 and saw blade 2 is fully wrapped around internally, improves
Protection effect.
The ball 5 of second ball 4 and first is stainless steel material, will not be got rusty, service life is long, it is ensured that rolling rubs
Wipe power small.
It the foregoing is only the utility model preferably embodiment, but protection domain of the present utility model not office
It is limited to this, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.
