Background technology

Hay mower is widely used in mowing by the mode selected by the hobby of people.Some operation pedestrian like and custom mower time, latter half of upper handrail makes slightly large strength and have a kind of sensation relying on and press down, and this is with regard to the unsettled possibility of the tilting virtually adding front-wheel; And the design of mower also should look after the comfortable of user and convenience as far as possible.Stick up also less before using petrolic mower, because of engines heavy.But the bad phenomenon of sticking up before sticking up particularly the near front wheel before also having occurs.For power-operated mower, because electromotor is lighter than engine, and electromotor axis will drive the hay knife that tactical diameter is very large, again can not too forward installation, and therefore the front-wheel of power-operated mower sticks up that to lift phenomenon more common.Say again, according to related standards such as GB4706.78-2005; IEC60335-2-77-2002; The standards such as EN836-1997, particularly EN836/A3-2004/4.2.3.2.1 ~ 4.2.3.2.3.3, all have the code requirement on 16.7 degree, slope.Add the husky kettle of counterweight in complete machine front portion, installation will change chassis, add three positions, hole, also will add sandstone, comparatively bother.Counterweight is because of heavier, and cost of transportation is also higher.

Separately there is common mower, as Fig. 10, moving head explodes figure instituteshow, without cutter, driven the moving head having nylon wire by series excited machine.When installing mower, and start the nylon wire in reel 25-3 is rotated, just can beat the grass.When line in short-term, once, reel aluminium head 25-3b touches ground to operator's pier pressure, reel spring 25-1 is compressed, and reel 25-3 is turned, make the nylon wire 134 in it lead to wire over inserted sheet 25-6, and unwrapping wire.The long line of releasing is pruned by blade 127.The used time is not placed on blade sleeve 126 on blade 127, has protective action.Moving head is beaten the grass effective, power saving lighter and handier than cutter, but because needing pier to press line, and cannot be contained on the common mower of wheel.

Common hay mower extensively adopts engine, and scope of activities is wide, but wants oil consumption, exhaust pollution environment.Some operation pedestrian likes with power-operated mower, but is subject to the restriction of power supply, and the extensive employing of this mower is also restricted.

Innovation design is being hovered for a long time as ghost, uses for reference and participates in European correlation experience for many years and repeatedly explore, and is thousand worries and good fortune has one to obtain.Such as, if imagine a device, central pull pulls bull stick, if reel aluminium head unwrapping wire can be made, light and handy moving head just can be adopted and power saving on hay mower; And for example fruit, counterweight need not husky kettle, also need not the tank of once improved, and on hay mower, establish accumulator, preferably establishes winder with easy access; Originally the damping of winder is sometimes malfunctioning unreliable, all knows that the malfunctioning once in a while of bobbin winoler is world-famous puzzle; Fortunately there is can using with the pipe winding device stopped and winder with drawing of just having worked out, so a kind of novel biased series motor power-operated mower, exactly existing moving head has again the mower of winder, has just arisen at the historic moment.Its resultant effect expands the scope of application, adds and suppress grass soil moisture conservation and safety, and fuel-efficient and environmental protection.

Though there is stall mower safety in three seconds, former brake reliability is not lasting; Because of the motor and belt wheel still skids stopped had; The radial centrifugal block for clutch use had is without multiple tooth, though test is passed through, just skids with polishing for a long time; When rotating in brake process, radial direction still has centrifugal obstruction effect, if change axis into, just stops soon without centrifugal obstruction; Former brake think suddenly once to smother stop dead, but because it gathers energy, things turn out contrary to one's wishes, vexedly stop as stretched and relaxed brake holding if change, kind here greatest, function wave dish brake interval degree of tightness is pulsed and the energy that scatters, be beneficial to and check, and extend life-span of brake pad, because of pressure always, to cling to then brake pad like grim death rubescent, and once tightly once then brake pad is not easily rubescent for relaxation pine.Sometimes contain steel hard object in meadow, and hinder cutter occasionally or cause the mower that topples; If when frontal collisions live support outpacking rubber skin and make live support slide bar retraction time and trigger limit switch, can profit crashproof.Crashproof security personnel and guarantee brake, mowing, it is optional to beat the grass, and live wire and region are large, and these are said and easily do difficulty, are the hard nut to cracks of power-operated mower always.

Why use winder ?because very long electric wire on the ground at random, when power-operated mower comes and goes mowing, sometimes because of carelessness just stepped on by pin, or be pressed onto by wheel, affect safety; Sometimes because of electric wire knotting or disorderly can twine again, cause line to fall short of and suspend mowing, or being gone to manage line by staff, adding potential safety hazard.Why winder to be installed on power-operated mower ?all knowing with crossing the people of power-operated mower, mowing often to have and leaking grass, must heavily cut, particularly when circumstance complication is mixed in lawn if any grove, just need to push away a few step into a few step and repeatedly repeat to mow in left and right; If winder is placed on far place, the electric wire near mower can not in time with drawing with stopping synchronous turnover, or can softly repeatedly to fall on the ground, and has to be stepped on or by the danger of wheel load, or can not line in time.Winder is installed on power-operated mower, and not only in order to replace counterweight, and in order to free to advance or retreat, described winder is in two kinds of dress methods at the front portion of mower and middle part, and its line outlet is all higher apart from ground, therefore is not easily stepped on or by wheel load.
