Background technology

Hay mower is widely used in mowing by the selected mode of people's hobby.When some operation pedestrian likes and is accustomed to using mower, make slightly large strength and have a kind of sensation that relies on and press down on latter half of upper handrail, this has just increased the unsettled possibility of perk of front-wheel virtually; And the design of mower also should be looked after the comfortable of user and convenient as far as possible.Use before petrolic mower and also stick up less, because of engine heavier.But before also having, sticking up the bad phenomenon of sticking up before the near front wheel particularly occurs.For power-operated mower, because electromotor ratio engine is light, and electromotor axis will drive the hay knife that tactical diameter is very large, again can not too forward installation, so the front-wheel of power-operated mower sticks up, and to lift phenomenon more common.Say again, according to related standards GB4706.78-2005 for example; 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, the code requirement that all has slope 16.7 to spend.In complete machine front portion, add the husky kettle of counterweight, installation will change chassis, add three positions, hole, also will add sandstone, trouble.Counterweight is because of heavier, and cost of transportation is also higher.

Separately there is common mower, as Figure 10, shown in moving head explosive view, without cutter, by series excited machine, driven the moving head that has nylon wire.When installing mower, and start the nylon wire rotation making in reel 25-3, just can beat the grass.When line in short-term, operator's pier is pressed, reel aluminium head 25-3b touches ground, makes reel spring 25-1 compression, and reel 25-3 is turned, and makes the logical wire over inserted sheet 25-6 of nylon wire 134 in it, and unwrapping wire.The long line of emitting 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, than the light and handy power saving of 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 as, uses for reference and participates in for many years European correlation experience and repeatedly explore, and is thousand worries and good fortune has to obtain.If, imagine a device, for example central pull pulls bull stick, if can make reel aluminium head unwrapping wire, just can on hay mower, adopt light and handy moving head and power saving; Fruit and for example, counterweight need not husky kettle, the also tank of improved once, and on hay mower, establish accumulator, preferably establish 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 having what just worked out is that winder can be used with drawing with the pipe winding device stopping, so a kind of series motor power-operated mower of novel biasing, exactly existing moving head has again the mower of winder, has just arisen at the historic moment.Its resultant effect is to have expanded the scope of application, adds and suppresses grass soil moisture conservation and safety, and fuel-efficient and environmental protection.

Though there is stall mower safety in three seconds, former not lasting by brake reliability; Because the motor belt wheel of stopping having still skids; The radially centrifugal block for clutch use having, without multiple tooth, though test is passed through, just skids with polishing of a specified duration; While rotating in brake process, radially still have centrifugal obstruction effect, if change into axially, just without centrifugal obstruction, stop soon; Former with brake think suddenly once to smother stop dead, but because it gathers energy, things turn out contrary to one's wishes, if change vexed stop into stretched and relaxed brake holding kind here greatest, function wave dish brake intermittently degree of tightness is pulsed and the energy that scatters, be beneficial to and check, and extend the life-span of brake pad, because pressure is always clung to like grim death, brake pad is rubescent, and relaxation pine once a tight next brake pad be difficult for rubescent.In meadow, sometimes contain the hard thing of steel, and hinder occasionally cutter or cause the mower that topples; If when frontal collisions is lived the outpacking rubber skin and making of support while living the slide bar retraction of support and triggered limit switch, can profit crashproof.Crashproof security personnel and guarantee brake, mow that it is optional to beat the grass, live wire and region is large, and these are being said and are easily doing difficulty, are being the hard nut to crack of power-operated mower always.

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