Description
Technical field
The present invention relates to a kind of mower, particularly relate to a kind of can the mower of quick-replaceable blade.
Background technology
Mower is a kind of machine tool for cutting the grass on a lawn, and it is made up of structures such as cutterhead, motor, blade, road wheel, control systems.The structure of general mower is that cutterhead is contained on road wheel, cutterhead is equipped with motor, the output shaft of motor is equipped with blade, blade utilizes the High Rotation Speed of motor to improve a lot in speed, save the activity duration of weeding workman, decrease a large amount of human resources.But there is a problem in this traditional structure, the replacing being exactly blade is very inconvenient.
In the practical application of mower, the replacement frequency of blade quickly.And in conventional art, blade is all be threaded with cutterhead by fixed forms such as screws, when changing, need with screwdriver, screw to be backed out, take off old blade, screwed on by screw with screwdriver, doing so extremely wastes time and energy again, but also user must be asked to carry screwdriver at any time for a rainy day.Such as publication number is the utility model patent that the name of 202773369U is called " mower cutterhead ", its blade mode be fixed on cutterhead be exactly with bolt by two fixing holes, blade is fixed on cutterhead; When needs are dismantled, need to back out two bolts.But blade can be stained with the dew on thick grass in use, contact with air for a long time in addition, be easy to cause blade and threaded bolt contacts place to be got rusty, also inconvenient during dismounting.
Summary of the invention
The object of this invention is to provide a kind of mower that can be convenient for changing blade, to meet the demand of user.
For achieving the above object, the technical solution used in the present invention is: a kind of mower, described mower has rolling disc, the edge of described rolling disc is provided with at least one group of cutting assembly, described cutting assembly comprises the connecting rod be fixedly connected with described rolling disc, be sheathed on the cutting element on described connecting rod, the butterfly be connected with described turn disc, the axial line of described connecting rod and the axial line of described rolling disc are parallel to each other, described cutting assembly at least has locking and unlocks two duties, when described cutting assembly is in the lock state, described butterfly by spacing for described cutting element on described connecting rod, when described cutting assembly is in released state, described butterfly and described connecting rod are separated.
Preferably, described cutting element offers at least one installing hole, described cutting element is set on described connecting rod by described installing hole.
Further preferably, described installing hole is circular hole.
Further preferably, gap is had between described installing hole and described connecting rod.
Preferably, described cutting element offers at least one place helix-type flute, described helix-type flute has the spiral mouth and fixing hole that are connected, and described connecting rod is located in described fixing hole vertically.
Preferably, described cutting element is blade.
Further preferably, described blade has at least two cut edges, place.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages: mounting portion cover on cutting element, when installing cutting element, can directly on connecting rod, then be stirred butterfly and lock by user; And when dismantling cutting element, only needing first to stir butterfly by it removes from latched position, then taking off cutting element, avoiding the inconvenience of generation when being connected by bolt or screw.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is further elaborated.
Mower of the present invention, based on mower of the prior art, has added cutting assembly at the edge of rolling disc 1.Accompanying drawing 1 is the schematic diagram of the rolling disc of mower of the present invention, and accompanying drawing 2 is the partial enlarged drawings in A portion in accompanying drawing 1, and 3, accompanying drawing is the cutaway view of rolling disc cutting assembly, and above three place's accompanying drawings combine and describe detailed construction of the present invention.Rolling disc 1 is circular, and be provided with at least 1 group cutting assembly in its edge, preferred version is for arranging 3 groups of cutting assemblies here, and its circumferential edges at rolling disc 1 is 120 degree, interval between any two.Cutting element 3 is preferably double-edged blade, and it has two cut edges 32, can directly be inverted by blade in the radial direction of rolling disc 1 like this after finishing using in cut edge, side, continues to use; Cutting element 3 is provided with mounting portion 31, in order to coordinate above-mentioned double-edged blade, preferably on cutting element 3, offers two mounting portions, place 31, so that can continue to be connected with rolling disc 1 when being inverted.The effect of connecting rod 5 is connection of rotating dish 1 and cutting element 3, specifically, one end and the rolling disc 1 of connecting rod 5 are fixed, here connected mode can be inlay connection or other interference fit form, connecting rod 5 can not be caused when working with rolling disc 1 to skid, the other end of connecting rod 5 needs sheathed cutting element 3, also namely through the mounting portion 31 of above-mentioned cutting element 3, cutting element 3 freely can be rotated on connecting rod 5.
Everywhere cutting assembly 2 is also provided with butterfly 4, this butterfly 4 is by being rotationally connected between rotating shaft 41 and rolling disc 1, the effect of butterfly 4 compresses cutting element 3 to make it be close on rolling disc 1, such cutting element 3 would not because of reasons such as vibrations from landing connecting rod 5, therefore butterfly 4 should be close to the end face of connecting rod 5, but when needs dismounting, need again butterfly 4 can allow open position, cutting element 3 can be taken off easily.Preferred version in accompanying drawing is that butterfly 4 is designed to rectangle, and rotating shaft 41 is arranged on one end of rectangle, and the width of rectangle is enough to the end face covering connecting rod 5.Here also can change according to the dissimilar shape of rolling disc 1 pair of butterfly 4 and the position of rotating shaft 41.
Accompanying drawing 4 and accompanying drawing 5 are the concrete shapes for mounting portion 31 in described cutting element 3, two designed embodiment.Accompanying drawing 4 is first embodiments, and its cutting element 3 is provided with two place's installing holes 33, and installing hole 33 is preferably circular hole here, is convenient to the size design to carrying out interference fits between circular hole 33 and connecting rod 5 like this.Accompanying drawing 5 is second embodiments, its cutting element 3 is provided with spiral line type groove 34, when mounted, need by installation end to similar spiral mouth 35, then rotating cutting elements 3, make connecting rod 5 be threaded in the fixing hole 36 of spiral, like this, due to when rolling disc 1 works, all active forces all concentrate on the side at S type edge 37, avoid the possibility that it skids off from spiral mouth 35.No matter be the first embodiment of accompanying drawing 4 or the second embodiment of accompanying drawing 5, all need butterfly 4 to compress cutting element 3 and do auxiliary fixing.
The present invention is easy to operate, after installation cutting element 3, do not need screw of screwing on, only need to stir butterfly 4, during dismounting cutting element 3, also only need remove butterfly 4, taking off cutting element 3, provide the user facility when not affecting properties of product.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
