Abstract

Safe type disk head of beating grass includes: the blade disc has fixed connection's upper cover and lower cover, has the sword of tibetan groove between upper cover and the lower cover, the blade has the cutting part that pin joint portion and pin joint portion extend, the pin joint deploy in hide the sword inslot and with the blade disc pin joint, the both sides and the tip of cutting part then have continuous sawtooth. Compared with the prior art, the utility model has the advantages of have the sword of tibetan groove on the blade disc, the blade meets to confine to all the time after the obstacle kick -backs hides sword inslot, safe and reliable more, the cutting part of blade can positive and negative two -way cutting, cuts more high -efficiently, is not afraid of the winding moreover.

Description

Safety-type disc type moving head
Technical field
The utility model relates to mower, specifically the safety-type disc type moving head of mower.
Background technology
Mower is a kind of machine tool for cutting the grass on a lawn, disc type mower wherein utilizes motor driving disc type moving head to mow, general and the application number of this disc type grass mowing head structure be 93226215.5 the scheme that discloses of Chinese utility model patent document similar, be made up of the structure such as cutterhead, blade, cutterhead utilizes centrifugal force that blade is opened when rotating, the blade of blade cuts towards the direction of rotation of cutterhead, if blade is encountered the hard object such as stone and can be flicked backward and avoid fracture during cutting, simultaneously operation can be carried out in barrier dead angle again.
But this disc-like type moving head often can only carry out cutting operation in a rotation direction, often also can cause blade resilience when can not once cut for more tough grass blade and repeatedly repeat cutting, thus causing blade to be wound cannot normally working.And blade run into obstacle resilience after easily upwards bounce, therefore there is potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of safety-type disc type moving head, and in prior art of can preventing, blade bounces the safety problem caused, and Double Directional Cutting can be provided to avoid blade to be wound.
To achieve these goals, the utility model adopts following technical scheme.
Safety-type disc type moving head, comprising:
Cutterhead, has the upper cover and lower cover that are fixedly connected with, has and hide cutter groove between upper cover and lower cover;
Blade, has the cutting part that articulated section and articulated section are extended, articulated section be placed in hide in cutter groove and with cutterhead pivot joint, the both sides of cutting part and end then have continuous print sawtooth;
Wherein, blade has at least three pieces of symmetrically arranged two pieces or equidistant distributions.
As the improvement of technique scheme, the cutting part of blade, its outer, bottom surface has cutting edge.
Compared with prior art, the beneficial effects of the utility model are:
Cutterhead has and hides cutter groove, blade is confined to after running into obstacle resilience hide in cutter groove all the time, more safe and reliable; The positive and negative Double Directional Cutting of cutting part energy of blade, cutting is more efficient, and is not afraid of winding.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of cutterhead of the present utility model.
Fig. 3 is the structural representation of blade of the present utility model.
Embodiment
As shown in Fig. 1 to Fig. 3, safety-type disc type moving head, comprising:
Cutterhead, has the upper cover 11 and lower cover 12 that are fixedly connected with, has and hide cutter groove 13 between upper cover 11 and lower cover 12;
Blade 2, has the cutting part 22 that articulated section 21 and articulated section 21 are extended, articulated section 21 be placed in hide in cutter groove 13 and with cutterhead pivot joint, the both sides of cutting part 22 and end then have continuous print sawtooth;
Cutterhead utilizes centrifugal force that blade 2 is opened when rotating, the cutting part 22 of blade 2 cuts towards the direction of rotation of cutterhead, if can flick from barrier when during cutting, the hard object such as stone encountered by blade 2, carry out cutting operation in barrier dead angle simultaneously, owing to hiding the existence of cutter groove 13, the spring scope of blade 2 is confined to hide in cutter groove 13 all the time, eliminates potential safety hazard.
Above-mentioned safety-type disc type moving head, both sides and the end of the cutting part 22 of its blade 2 then have continuous print sawtooth, and namely no matter cutterhead rotates forward, reverses, and blade 2 can form effective cutting.Often also can cause blade 2 resilience when can not once cut for more tough grass blade, adopt above-mentioned safety-type disc type moving head, can repeatedly switch direction of rotation to its repeatedly repeat cutting, thus stop blade 2 by grass blade be wound around cannot normally work.
As shown in Figure 1, blade 2 has three pieces of equidistantly distribution, and when High Rotation Speed, the cooperation of three pieces of blades 2 can be cut more thorough.
As shown in Figure 3, the cutting part 22 of blade, its outer, bottom surface has cutting edge, makes cutting part 22 have better cutting efficiency.
For a person skilled in the art, the structure that can disclose according to the utility model and principle obtain other various corresponding change and distortion, and all these change and distortion all belongs to protection category of the present utility model.
