Background technology

Hay mower is widely used in the selected mode of hobby by people to mow.Some operation pedestrians like During with custom hay mover, slightly larger strength is made on latter half of upper handrail and has a kind of sensation for relying on and pushing, this is with regard to nothing The hanging possibility of the tilting of front-wheel is added in shape；And the design of hay mover should also look after the comfortable and square of user as far as possible Just.Also lacked using being stuck up before the hay mover of petrol engine, because of engines heavy.But stuck up before particularly the near front wheel is stuck up before also having Bad phenomenon occur.For power-operated mower, because motor is lighter than engine, and motor axis will drive revolution Diameter very big hay knife, too forward can not be installed again, therefore to stick up lift phenomenon more common for the front-wheel of power-operated mower.Say again, According to relevant standard 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, the code requirement for having 16.7 degree of slope.Add in complete machine front portion and match somebody with somebody Weight sand kettle, installation will change chassis, add three hole positions, also want gaza's stone, cumbersome.Counterweight is because heavier, and cost of transportation is also higher.

Separately there are common grass-mowing machine, such as Figure 10, shown in moving head explosive view, without knife, being driven by series excited machine has nylon The moving head of line.When installing grass-mowing machine, and starting rotates the nylon wire in reel 25-3, with regard to that can beat the grass.When line in short-term, behaviour Once, reel aluminium head 25-3b touches ground to author's pier pressure, compresses reel spring 25-1, and turns reel 25-3, makes in it Nylon wire 134 lead to wire over inserted sheet 25-6, and unwrapping wire.The long line released is trimmed by blade 127.The used time is not blade sleeve 126 are placed on blade 127, there is protective action.Moving head effect of beating the grass is good, power saving lighter and handier than knife, but because needing pier to press line, and nothing Method, which is mounted in, to be had on the common hay mover of wheel.

The common widely used engine of hay mower, scope of activities is wide, but wants oil consumption, exhaust pollution environment.Some Operation pedestrian likes using power-operated mower, but is limited by power supply, and the widely used of this hay mover is also restricted.

Innovation design is hovered such as ghost for a long time, is used for reference and is participated in European correlation experience for many years and repeatedly explore, can Meaning thousand is considered and good fortune has one to obtain.If imagining a device, such as central pull pulls bull stick, if can put reel aluminium head Line, just can the power saving using light and handy moving head on hay mower；And for example fruit, counterweight is without husky kettle, without once improving The tank crossed, and battery is set on hay mower, preferably set winder with easy access；Originally the damping of winder is sometimes Failure is unreliable, and the failure once in a while for both knowing about bobbin winoler is world-famous puzzle；Fortunately have just worked out with draw with the pipe winding device stopped I.e. winder can use, and then, a kind of series motor power-operated mower of new biasing, exactly existing moving head has winder again Hay mover, just arise at the historic moment.Its resultant effect is to expand to use scope, strengthens the soil moisture conservation of pressure grass and safety, and fuel-efficient And environmental protection.

Though there is stalling hay mover safety in three seconds, original is not lasting with brake reliability；Because have stop motor and belt wheel still Skid；Some radial direction centrifugal block for clutch use, though test passes through, are just skidded without multiple tooth with long polishing；When being rotated in brake process radially Still there is centrifugation obstruction effect, if being changed to axial direction, just obstructed without centrifugation and stop soon；Original is thought once to smother suddenly with brake stops dead, But because it gathers energy and things turn out contrary to one's wishes, be apt to if vexed stop as stretched and relaxed brake holding is changed it is greatest here, function wave disk brake interval Elastic pulsation and the energy that scatters, beneficial to checking, and the life-span of extension brake pad, send out because pressure always clings to then brake pad like grim death It is red, and relaxation pine once it is tight once then brake pad be difficult it is rubescent.Sometimes the hard thing of steel is contained in meadow, and hinders knife occasionally or causes to topple Hay mover；If when frontal collisions live support outpacking rubber skin and making live support slide bar retraction when and trigger limit switch, can Sharp anticollision.Anticollision is ensured public security and ensured brake, and mowing is beaten the grass optional, and live wire and region are big, and these, which are said, easily does hardly possible, always It is the hard nut to crack of power-operated mower.

Why winder is usedBecause very long electric wire on the ground at random, when power-operated mower comes and goes and mowed, have When imprudence just stepped on by pin, or be pressed onto by wheel, influence safety；Sometimes it can knot or disorderly twine because of electric wire again, cause line to fall short of And suspend and mow, or reason line is gone by human hand, add potential safety hazard.Why winder is attached on power-operated mowerWith The people for crossing power-operated mower both knows about, and mowing has leakage grass often, must cut again, is particularly mixed in environment complexity if any grove During lawn, it is necessary to enter several steps and push away several steps and left and right multiplicating mowing；If winder is placed near far place, hay mover Electric wire can not in time with drawing with stopping synchronous turnover, or can it is soft it is repeated fall on the ground, have and stepped on or by the danger of wheel load, or not Can timely inlet-outlet line.Winder is attached on power-operated mower, it is described not only in order to replace counterweight, and in order to free to advance or retreat Winder in the front portion of hay mover and two kinds of middle part dress methods, its line outlet is all higher away from ground, thus be difficult to be stepped on or by Wheel load.
