China Patent Publication No. CN205030136U patent document discloses a kind of lustration type grass mower, including frame,
The rear portion of frame, which is connected with, pushes away handle hand, and the bottom of frame, which is provided with road wheel, frame, to be covered with body shell, body shell
Bottom is provided with careless power-driven mechanism is cut, and the clutch end for cutting careless power-driven mechanism stretches out the body shell, cuts grass dynamic
The clutch end connection of power drive mechanism cuts careless cutterhead positioned at bottom of the frame.Careless cutterhead connection is cut in above-mentioned technical proposal
In the lower section of body shell and body shell lower surface is stretched out in, when running into the raised adamant on lawn during grass is cut
When, because the terrain clearance of frame lower surface is higher than careless cutterhead terrain clearance is cut, frame can smoothly cross projection, but subsequently
The careless cutterhead cut stretch out the lower surface of frame, so the blade hit that can cause to cut on careless cutterhead is damaged to projection adamant
It is bad.
Utility model content
The purpose of this utility model is to provide a kind of rotary cutting apparatus of grass mower, by using the rolling for stretching out in blade
Wheel can touch raised adamant in advance during grass is cut, and realization is smoothly crossed, it is to avoid the blade in rotary course
Collide raised adamant and be damaged.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of rotation of grass mower
Cutter device, including rotary shaft, the cutterhead for being connected to rotary shaft, some blades for being uniformly arranged along cutterhead circumferencial direction, it is described
Cutterhead is connected with installation axle away from rotary shaft end face, and the mounting sleeve is provided with bearing, and the bearing outer wall is arranged with and row
Wheel shaft is walked to the mounting rod being vertical setting, the mounting rod is rotatably connected to roller, the roller away from cutter head center one end
Terrain clearance is less than blade terrain clearance, and the distance of the roller and cutter head center is more than blade away from cutterhead one end and cutterhead
The distance between heart.
By using above-mentioned technical proposal, during grass is actually cut, when grass mower has crossed terrain clearance less than under it
During the raised adamant of end face terrain clearance, during grass mower walks on, because the distance of roller and cutter head center is big
In blade outermost end and the distance of cutter head center, roller conflicting that can first on mounting rod avoids rotation in raised adamant
In blade direct collision to raised adamant, staff can then be rolled and smooth using roller along raised adamant afterwards
Cross, so that protective effect is served to the blade in rotation, while grass can be also cut to progress around raised adamant, and nothing
It need to specially be bypassed during trimming and subregion can not can be realized and cut careless action.
The utility model is further arranged to：The rotary shaft vertically slides connection and radially fixed has flexible
Bar, the expansion link is fixedly connected on cutterhead away from rotary shaft one end.
By using above-mentioned technical proposal, using the expansion link vertically moved up and down, can make whole cutterhead with
And be connected to cutterhead roller can be realized during grass is cut it is flexible up and down, when roller scrolls up along raised adamant
When, can be by making the terrain clearance of grass mower shell lower surface constant in expansion link automatic retracted to rotary shaft, so that nothing
It need to be lifted in grass mower and make road wheel liftoff, the shell of whole grass mower can be kept to remain able to by road wheel smoothly

By using above-mentioned technical proposal, expansion link is set up and down to be transported in the slip hole of rotary shaft along vertical direction
It is dynamic, while rotary shaft is driven expansion link and is connected to the cutterhead of expansion link again makees continuous rotating motion, and then complete
Cut careless action.
The utility model is further arranged to：The expansion link is connected with spring away from cutterhead one end with rotary shaft inwall.
By using above-mentioned technical proposal, a position-limiting action can be played to the end of expansion link by spring, it is to avoid
Cause expansion link to detach rotary shaft because manpower lifts whole grass mower, careless mistake is being cut in the presence of expansion link and spring
The floating effect of whole cutterhead and roller is realized in journey, when expansion link is bounced back in rotary shaft, the conflict of spring can be relied on
Power and roller is remained and contact at lawn, and then realize that grass is cut in normal rotation.
The utility model is further arranged to：The bearing outer ring is arranged with terminal pad, and the mounting rod is justified along terminal pad
Circumferential direction is corresponded with blade and is provided with several, and the mounting rod is placed between adjacent knife blades.
By using above-mentioned technical proposal, auxiliary stopper effect can be played using the roller on some mounting rods, and
And when whole grass mower is turned, it is possible to use the roller in all directions is directly oriented to；And each mounting rod
Corresponded with each blade, so as to play comprehensive protective effect to blade, not only in the direction of advance of road wheel
On blade is played a protective role, cutterhead be able to can be played a protective role for one week.
The utility model is further arranged to：Away from cutterhead one end, vertically sliding is connected with tune to the mounting rod
Pole, the adjusting rod is connected with rotation seat, and the rotation seat is rotating with roller；The adjusting rod be threaded with to
Tightly in the locking nut on mounting rod surface.
By using above-mentioned technical proposal, by adjust the terrain clearance of roller can directly change blade on cutterhead from
Ground level, so as to be adjusted according to actual cutting-height demand, makes its more practicality, also can be according to actually cutting grass
Lawn situation be adjusted come the terrain clearance to blade.
The utility model is further arranged to：Fastening bolt group, the fastening spiral shell are connected between the blade and cutterhead
Bolt group includes being arranged in cutterhead and being threaded with pushing against the thread segment of nut, being shaped in thread segment and section is square simultaneously
Be matched with the square neck section of cutterhead, be connected to square neck section and be rotationally connected with the light bar segment of blade, the light bar segment integrally formed with
Contact at the bolt end of blade face.
By using above-mentioned technical proposal, when installing blade, it is matched with cutterhead using square neck section to realize to fastening spiral shell
The positioning of bolt group and cutterhead, enables cutterhead to drive square neck section to realize and rotates, and avoid producing relative rotation between the two；According to
By being rotatably assorted for light bar segment and blade, when the blade in rotary course gets to stone, blade can impact moment according to
Depend on rotation to realize to rebound, it is to avoid occur strong rigid shock between the adamant such as blade and stone, extend blade
Service life；Final utilization pushes against nut and whole fastening bolt group is fixed, and makes blade without departing from cutterhead.
In summary, the utility model has the advantages that：With reference to the rolling on the one-to-one mounting rod of blade
The stretching motion of wheel and expansion link in rotary shaft, can realize the floating effect of cutterhead and blade during grass is cut, can
Walked, steadily cut with successfully crossing raised adamant, and making grass mower the enterprising every trade in lawn that is placed in that can still stablize
Blade hit is avoided to cause to damage to raised adamant during grass.
