Abstract
The invention relates to a working head of a rotary grass cutter, and the working head comprises a circular cutter holder, a cutter blade and a cutter rest, and is characterized in that at least one cutter cavity with an opening facing an edge is arranged on the circular cutter holder; a guiding chute capable of enabling the cutter rest to slide inwards and outwards is arranged in the cutter cavity; an inner stop block and an outer stop block are arranged on the guiding chute; the cutter blade is arranged on the cutter rest; the cutter rest is arranged in the guiding chute in the cutter cavity in the circular cutter holder. When the working head of the grass cutter rotates at high speed, a sharp circular cutting edge is formed, larger cutting force can be borne in a grass cutting direction, so that the cutter blade cuts with high efficiency and is self-cleaned; when larger resistance is encountered, the cutter blade is retracted into the cutter cavity of the cutter holder along with the cutter rest, so that the operation safety is ensured, the cutter blade is effectively protected and an obstacle can be got over smoothly; the sliding part of the cutter rest is arranged in the closed cutter cavity and effectively prevents blockage caused by straw pulp and other impurities, the structure is simple and reliable, and the installation and maintenance are easy; a part of the cutter holder which is close to the edge forms a protective wall when rotating at high speed, so that the cutter cavity can be further sealed and the cutter holder can be further protected.
Description
Technical field
The present invention relates to a kind of mower, particularly relate to a kind of rotary mower working head.
Background technology
Rotary mower is used for the finishing on lawn, and is easy and simple to handle, the efficient height, and the rotary mower working head has two kinds at present, and a kind of is the nylon rope formula, and a kind of is blade type.Nylon rope formula working head is that nylon rope interrupts grass when rotating by high speed, and efficient is relatively low, and nylon rope is easy to often replacing of wearing and tearing; The blade type working head can be realized efficient cutting, for safety with effectively avoid barrier such as stone, insert design is become between two disks, and a movable rotation-shaft is arranged, and blade can be received between two disks when running into big resistance.Because existing blade type working head blade can not bear big cutting force on the mowing direction, blade often subsidiary straw pulp is recovered in the cutterhead, having reduced mowing efficient and blade is easy to be influenced the mowing effect by the straw pulp adhesion, existing blade type working head blade recovering mechanism is in the state of exposing, stopped up by foreign material such as straw pulps easily yet and lost efficacy, reliability is not high.
Summary of the invention
For effectively addressing the above problem, the object of the invention is to provide a kind of rotary mower working head, realizes efficient, safety mowing, and is simple in structure, reliable.
The present invention takes following technical scheme to realize:
A kind of rotary mower working head, comprise the circular tool rest that is installed on the output shaft, blade and knife rest, it is characterized in that having an opening at least towards the cutter chamber at edge at described circular tool rest, be provided with in the described cutter chamber and can allow the guide chute of the inside and outside slip of knife rest, also be provided with inside and outside block on the described guide chute, described blade is installed on the knife rest, and described knife rest is installed in the guide chute in the cutter chamber.
Further, described rotary mower working head is characterized in that described opening towards the cutter chamber at edge straight forming on tool rest, or forms by butt joint more than two.
Further, described rotary mower working head is characterized in that described guide chute is arranged in the cutter chamber, or is arranged on the knife rest.
Further, described guide chute is characterized in that can allowing knife rest install from outside to inside along cutter chamber opening at described guide chute.
Further, described rotary mower working head is characterized in that being provided with inside and outside block in described guide chute, and internal stop is a locating surface on the tool rest, and outer baffle block is the stop bit screw that screws in from tool rest.
Further, described rotary mower working head is characterized in that described blade exposes the tool rest marginal portion for circular.
Further, described rotary mower working head is characterized in that the described tool rest part that keeps to the side has a following extended surface that extends downwards, and described tool rest edge is provided with an outer facade.
The invention has the beneficial effects as follows:
Form sharp circular cutting edge when 1, working head rotates at a high speed, on the mowing direction, can bear big cutting force, realize high-efficient cutting and automatically cleaning blade, can receive in the cutter chamber of tool rest with knife rest when running into big resistance blade, guarantee handling safety, effectively protected blade also can clear the jumps smoothly;
2, blade is installed on the knife rest, and the knife rest slipper is located at foreign material such as effectively preventing straw pulp in the cutter chamber of sealing and stops up, and is simple in structure, reliable, and is easy to installation and maintenance.
3, tool rest keeps to the side and partly forms protecting wall when rotating at a high speed, can further seal cutter chamber and protection tool rest.

Embodiment
Below in conjunction with accompanying drawing the present invention is done concrete being described below:
As shown in Figure 1 and Figure 2, rotary mower working head of the present invention, circular tool rest 2 is installed on the output shaft 1, the opening of two symmetries is arranged towards the cutter chamber at edge V on the circular tool rest 2, have in the V of cutter chamber and can allow the guide chute S of knife rest 3 inside and outside slips, knife rest 3 is installed in the guide chute S, the internal stop of guide chute S is locating surface P, the outer baffle block of guide chute S is the stop bit screw 6 that screws in outside tool rest 2, blade 4 is installed on the knife rest 3 by screw 7, two pins 5 are housed on the knife rest 3, and circular tool rest 2 fixes by nut 9 and pad 8.Blade 4 will rotate and form cutting edge C when as shown in Figure 2, rotary mower working head of the present invention is worked.
Fig. 3 has illustrated rotary mower working head knife rest installation process of the present invention.During installation earlier with knife rest 3 along b in the guide chute S that inserts cutter chamber V, screw in stop bit screw 6 again and get final product.Screw out stop bit screw 6 during dismounting and just can take out knife rest 3.
As Fig. 1, Fig. 2, shown in Figure 4; the following extended surface M that downward extension is arranged in the marginal portion of circular tool rest 2; circular tool rest 2 edges are provided with an outer facade N, work at present that extended surface M will effectively protect working head, and the protecting wall of formation can be protected blade better when outer facade N rotated at a high speed.
