Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1 to Figure 3, the utility model provides a kind of grass trimmer cutter head assembly cleaned automatically, including protection
Harvest mechanism 1 and cleaning transmission device 2, the protection harvest mechanism 1 are fixedly connected with cleaning transmission device 2.
In present embodiment, protection harvest mechanism 1 can carry out cutting blade during grass trimmer works effective
Ground protection avoids the collision of the hard object generation such as blade and stone and leads to the damage of blade, substantially prolongs the use of blade
Service life, cleaning transmission device 2 are not only that protection harvest mechanism 1 provides sufficient driving force, at the same can also automatically to blade into
Row cleaning, ensure that the cleaning of blade, avoids impurity liquid corrosion caused by it on blade.
The protection harvest mechanism 1 includes cutterhead 3, is equipped with several mounting grooves 4 in the cutterhead 3, in the mounting groove 4
Cushion 5 is installed on side, the hollow protective jacket 6 of arc, the hollow protective jacket 6 are fixedly installed in the mounting groove 4
Arc circumferential surface is equipped with protective device 7, and the cutting blade 8 of arc, the cutting blade are movably installed in the hollow protective jacket 6
Contraction spring 9 is fixedly connected between 8 and 6 medial surface of hollow protective jacket, the cutting blade 8 is equipped with and 5 phase of cushion
The dashpot 10 matched.
In present embodiment, protect protective device 7 in harvest mechanism 1 can be to cutter during grass trimmer works
Piece is effectively protected, and is avoided the collision that the hard object such as blade and stone occurs and the damage for leading to blade, is substantially prolonged
The service life of blade.
In the present embodiment, protective device 7 has shifted the hard object such as external stone onto cutting blade in rotary course
8 both ends avoid cutting blade 8 and collide during rotation with the hard object such as stone and cause to damage.When cutterhead 3 revolves
When turning, the cutting blade 8 in hollow protective jacket 6 is subject to centrifugal forces, and is thrown away out of hollow protective jacket 6 and with cutterhead
3 rotate together and carry out mowing task, and the wherein setting of cushion 5 and dashpot 10 is played during cutting blade 8 is thrown away
Certain buffer function avoids cutting blade 8 and fierce collision occurs with mounting groove 4 inner wall and damages；When cutterhead 3 stops
Spin-ended cutting blade 8 is retracted in hollow protective jacket 6 under the pulling force effect of contraction spring 9 when turning, and hollow protective jacket 6 is to cut
Cutting blade 8 provides the space of storage.
The protective device 7 includes the contraction frame 11 being fixedly mounted on side of hollow 6 arc week of protective jacket, the contraction frame
