Description

Improved blade is from the clutch mower

Technical field

The present invention relates to a kind of hay knife that is used for the hay mower that places such as garden, park and road next door, court cut the grass on a lawn, especially improved blade is from the clutch mower.

Background technology

Hay mower is widely used in not mowing from walking the mode of not walking certainly sometimes sometimes by people's hobby is selected.The operation pedestrian spurs from walking control crank, through steel wire rope and driving lever, makes clutch on-off, so that sometimes from walking sometimes not from walking.The driven wheel speed-reducing clutch of the traverse gear of prior art is to be driven by the belt pulley that is contained in engine spindle.And the engine spindle mowing-apparatus, like Fig. 5. shown in the engine spindle mowing-apparatus explosive view, by drive pulley (11), cushion cover (12), key (13), tool rest (14), original cutter (15), big pressure pad circle (16), fastening bolt (17) is formed; Generally speaking, tool rest is absolutely necessary.The conventional used part of mowing-apparatus is more more expensive; Also heavier, rotary inertia is bigger, and power hungry is more; And cutter is to be rigidly connected, and when running into foreign material such as water pipe, is very stiff and demanding, does not have security protection.Only there is sword the side of common hilted broadsword and anodontia, and its sword is prone to blunt, runs into cane and cuts badly, usually tears; Particularly its end face along circumference is anodontia, and end face is high at the rotating speed of circumferential location, and it is strong to cut off function, thus the end face of common hilted broadsword anodontia be very big loss to ablation energy.

Hay mower is widely used in mowing by the selected mode of people's hobby.Because the mobility of the mower of hand push is poor, and when mowing in the practice, because the narrower swath in mower front portion often has generation so repeat to cut and leak the phenomenon of cutting, must goes to mend and cut, it is very arduous that operator's walking is mowed.If use sitting type, also cry to drive mower, then be seated than stand and feel different, but noise is big.Noise reduction and to subtract the consumption task very big.

Silencer as the internal combustion engine silencing equipment of put-put particularly, is installed in exhaust doorway on the cylinder cover by extensively, reduces the noise of engine operation process.All there is relevant regulation countries in the world to the limiting value of the noise of various traveling vehicles and mower, and exhaust silencer comes to this one for reducing the device that exhaust noise is given birth to.The performance evaluation of silencer mainly contains acoustical behavior, indexs such as aerodynamic quality and structural behaviour.The considerable part of internal combustion engine belongs to pulsating nature low-frequency noise source, adopts resistance or impedance multiple and property and micro-perforated plate muffler more.Mostly the silencer of common internal combustion engine is the three-chamber silencer in particular for the silencer of put-put, and the noise elimination effect is limited; And outside must have bigger containment envelope, but itself not noise elimination effect.Moreover its shell temperature rise is higher, hot, influences safety.If add anechoic trap as improvement.Improve the noise reduction of mowing-apparatus and cutter and subtract consumption also very important.

Artificial foot protection all has related request at standard STD.BSI EN 836-ENGL 1997 and GB 4706.78-2005/IEC 60335-2-77:2002.The mowing of most mowers highly has many retainings adjustable, and this safety to operation pedestrian's pin must be by the security regulations of strict control.This pin test that normally rehearses.But false pin test palpus every day test location is more, and topped product quantity very little.To such an extent as to the mower of shipment is arranged, but measured false pin safety by the people individually, then all influence the mower order.Improved idea allows hay knife be elevated at several millimeters on chassis often.But because the sheet metal that cutter is the part of elongated bar bend, since tolerance, the reason of form and position tolerance and assembling cumulative errors, and the point of a knife at two ends is not high not the hanging down on a circumferential plane of just very difficult assurance in large quantities of actual productions; Just in case the thing difficulty that takes place is avoided, but also to guarantee ten thousand none go out safety problem.If with the noise abatement material mowing table and mower are improved, and are improved cutter, be expected to receive the effect of security protection and noise abatement.

Phenomenon is cut in leakage for fear of cause in the adjacent gap of two cuttves, two cuttves of original sitting type mower, normally one in front and one in back.Please referring to Figure 51, this is the transmission sketch map of one in front and one in back two cuttves of original sitting type mower, among the figure, 23a be first cutter the axle on belt pulley, 23b be second cutter the axle on belt pulley, the 11st, the belt pulley of engine.The strip of two cuttves is to hang down mutually and reverse the commentaries on classics, so that mutually noninterfere; Usefulness be two-sided V-belt, also used three regulating wheels, main shortcoming is because of before and after cutter has, and makes to strengthen before and after cutting dish; Cause wheel base to strengthen, complete machine lengthening, the car turning radius become big; Vertical potentiality coefficient of stability variation, cost is added, and these all are undesirable.Two cuttves of another kind of original sitting type mower, though be not tandem, referring to Figure 52, because of two cuttves are reverse commentaries on classics so that mutually noninterfere, usefulness be two-sided synchronous band, also handy two synchronous tensions are taken turns, this makes the cost increasing.

During actual the mowing, meet stone sometimes and hinder cutter.Press the regulation of blade test again, with No. 45 steel, diameter 30mm, the seamless steel pipe of wall thickness 3mm; Put in blade and cut the district, do not allow fracture, but flexible; This inspires blade that we make improvements from the clutch mower, also inspires us to make the multistage flail knife, and the cutter of protection is arranged.

Summary of the invention

It is constantly to improve with endless that science is improved.Changed repeatedly cutter earlier, changed multiple and cutter again from the relevant part of clutch.

For the used part of mowing-apparatus of the routine that overcomes the hay mower prior art more; Rotary inertia is bigger; Power hungry is more; And cutter is to be rigidly connected, and does not have the shortcoming of security protection, and the present invention provides a kind of improvement of hay mower cutting mechanism; It is the cutter of not wanting independent tool rest that is used for hay mower; The hay mower hay knife that is called no tool rest, one can make part reduce, and cost reduces; Two can make weight saving, and consumed power reduces; Three can make it have the function of security protection.Anodontia for sword is only arranged in the side that remedies common hilted broadsword again, it is blunt that its sword is prone to, and runs into cane and cut badly, usually tears; Particularly its end face along circumference is anodontia; And end face is high at the rotating speed of circumferential location; The cut-out function is strong; So the end face of common hilted broadsword is anodontia is the shortcoming to the very big loss of ablation energy; The present invention is improving for many years; Material for example; Heat treatment; Mechanism; Form, and for example the hay mower of described no tool rest provides a kind of multi-tooth hey knife for lawn mower especially with on the basis of hay knife; The multiple tooth length that has increased blade than hilted broadsword greatly; Have many folding swords and multiple impact cutting angle and slip cutting angle are arranged, help strengthening careless bar of cutting and straw usefulness, mill structure at the bottom of the hunchbacked formula of shear blade; Make it that self-grinding and wear-resisting persistence arranged, and save power consumption than former hilted broadsword is sharper because of multiple tooth.

The present invention solves the technical method that its technical problem takes:

This is the ingenious combination of two types of junctures in fact, saves heavy tool rest exactly, and the moulding that direct punching press can supply connect on the steel plate of cutter; Or glued joint with welding and to make, be the cutter of not wanting independent tool rest in a word, be tool rest and cutter are integrated, also be provided with the key of security protection on it, can be generically and collectively referred to as the hay mower hay knife of no tool rest.

A kind of engine spindle mowing-apparatus does not particularly have the hay mower hay knife of tool rest, on the steel plate of cutter, in the riding position zone of engine spindle and fastening bolt (17); Be provided with pit (2), key (1), keyway (3) is like Fig. 1; Fig. 3, Fig. 4, Figure 10 and shown in Figure 11; It is characterized in that: the internal diameter of described pit (2) equals or tolerance is slightly larger than the external diameter of engine spindle, and the centre of the bottom of described pit (2) is porose, so that pass fastening bolt (17); The band of position of laying key at the edge of described pit (2); Be provided with key (1); It is characterized in that: described key (1) is rectangle; Be from the steel plate of cutter; Utilize material and punching press bending and moulding, or make with welding or splicing, and the two sides of its square-section; At least one side, installation and sticker are in the keyway of engine spindle; The root of particularly described key (1); Just the steel plate of key (1) and cutter and with the connecting portion of the band of position of laying key at the edge of described pit (2); The crack arrest groove that the punching press bending is arranged; So that correctly select suitable shear strength; Make and can mow through key, again can be when running into water pipe key the root overloading and protect.Describedly correctly select the brief and concise introduction of method of suitable shear strength following: the root of making described key (1) can be used the crack arrest channel process of less important wall.Less important wall is meant the panel beating wall that is connected on other thin-walled, can be counted as the subitem of main wall.The crack arrest groove of the root of key has seam crack arrest groove, and no crack arrest groove stretches the crack arrest groove, rectangle crack arrest groove, and Long Circle crack arrest groove, preferably choosing has seam crack arrest groove.Suggestion is with computer bender and PROE, and available system acquiescence equation is with the Y factor or the K factor; Or with predefined bending table; Or with the bending table that customizes; Consider material behavior and compensation by system.If the bending table of customization is not specified to sheet metal component, available following formula calculates length of run:

L＝(π/2xR+YxT)xθ/90

In the formula, L is the length of run of key; R is the inner radius of key; Y factor this desirable 0.5; T is a steel plate thickness, and it is prominent protruding to beat edge break and many places, can improve the modulus of the mechanics of materials, reduces steel plate thickness; θ is the bending angle, can between 80-100, choose.The Y factor and the K factor are by the defined part constant in the position of the neutral bending line of the relative thickness of sheet metal component material.The K factor is distance (δ) and the ratio the material thickness (T) from neutral bending line to inboard radius bend, and its formula is K=δ/T.Y factor is the length of neutral bending line and the ratio between the material thickness (T), and its formula is Y=Kx (pi/2).Can accessing text and HTML sheet metal component report and the precision of sheet metal component is set.Select suitable shear strength method two are the methods of facts have proved; Root in described key (1); Just the steel plate of key (1) and cutter and with the connecting portion of the band of position of laying key at the edge of described pit (2); Not have wheel be the crack arrest groove that the punching press bending is arranged, or with welding or glued joint and make, facts have proved as if still its intensity is too high; Then take material reducing to cut out method; Promptly, dig material the root portion cross section of key is attenuated, to select suitable shear strength at the root of its key.The characteristic of described keyway (3) is, the band of position of laying common key (13) at the edge of described pit (2) is provided with the same wide keyway of keyway with engine spindle, and this is subsequent use for some occasion, when for example adding woodruff key, when for example adding spare key.The steel plate middle part of cutter, it is prominent protruding in to strengthen attenuate to beat edge break and many places.

Wind wing elliptical aperture (28) on the wind wing of cutter and wind wing honeycomb (29) have the booster action of noise reduction.

The described mowing-apparatus that noise reduction is arranged that drives the included vehicle frame below of mower that noise reduction measure and hydraulic stepless speed change are arranged comprises and highly regulates part and mowing part; Referring to Fig. 5; Highly regulate part; Press parallelogram principle; By the preceding dead axle (58a) and the back dead axle (58c) that are located on the vehicle frame; And be located at preceding moving axis (58b) and the back moving axis (58d) that cuts on the dish (58) and be attached thereto moving rod member; And the steel wire rope (58h) that supplies pulling usefulness; Sector gear (58g); Ratchet (58f) and heighten handle (55) and form; It is characterized in that: described preceding dead axle (58a) and the back dead axle (58c) that is located on the vehicle frame; And be located at the preceding moving axis (58b) that cuts on the dish and back moving axis (58d) is four summits of parallelogram; Its corresponding limit is parallel in twos and equal; So, spur steel wire rope (58h) through heightening handle (55) in any case, and through sector gear (58g); Ratchet (58f) comes to several gears of heightening; The line of preceding dead axle (58a) on the vehicle frame and back dead axle (58c), always with cut dish on preceding moving axis (58b) be parallel with back moving axis (58d), thereby at the upper and lower translation that has fundamentally guaranteed to cut dish and operate as normal; Can find out that from Fig. 6 described sector gear (58g) has multiple tooth, existing preferred 10 teeth have 10 grades, and for example can cut height and transfer at 10-100mm, or by 25-85mm commonly used.Referring to Figure 24, the power of the part of mowing passes to first tool rest from engine spindle (51) through belt (61), again through being with (63) to pass to second tool rest synchronously, so that drive hay knife (60) work; As improvement, referring to Figure 33 and Figure 16, described hay knife (60) is provided with two or more wind wings, twines grass in order to cut off, and on described wind wing, is provided with a plurality of cutting edges, and the angle on the two sides of described cutting edge is not the right angle, is preferably less than the angle or the acute angle of 60 degree; Further as improving, described hay knife (60) is provided with a plurality of hexagonal holes, or further improves, and described hay knife (60) is provided with a plurality of like honeycomb or like the convex-concave of wedge (29), is noise reduction in order to the flow through audio frequency of the little air-flow of high speed of cutter of change.

The spy provides the mowing graphical designs partly and preferred method of thinking of the mowing-apparatus of noise reduction, is a significant contribution of the present invention.As previously mentioned, the one in front and one in back scheme of two cuttves of original sitting type mower, usefulness be two-sided V-belt, also used three regulating wheels, because of before and after cutter has, make and strengthen before and after cutting dish, cause the complete machine lengthening.Two cuttves of another kind of original sitting type mower, though be not tandem, because of two cuttves are reverse commentaries on classics, usefulness be more expensive two-sided synchronous band, also handy two synchronous tensions are taken turns, this makes the cost increasing.Can find with two cuttves, be one in front and one in back, do not make to cut the increasing of dish front and back, and oppositely do not change, and two-sided synchronous band that need not be more expensive, grass does not leak, and what way does the approach that cutter does not bump use? Answer is yes.Use the diagram optimum seeking method: two point widths of getting bar shaped cutter (20) are diameter D, are that (23a is 23b) apart from being A at the belt wheel center by the gyroaxis of two cuttves; 2 circles draw; Referring to Figure 25, the anterior part that two circles intersect representes that with the filling hachure width B is exactly the heavy swath B that grass does not leak; Be that diameter is justified again with A, the angle of circumference perseverance is the right angle, hangs down mutually because of establishing two cuttves, and is synchronous rotation, so two two limits that cutter is an angle of circumference can be drawn a plurality of angles of circumference in addition and come preferred.Formula is arranged: B=D-A.Referring again to Figure 26, change A gets belt wheel apart from A=0.618D by optimum seeking method 0.618 method earlier, and mapping strengthens A more gradually, is to the maximum near D; Shown in the figure heavy swath B of maximum and the minimum A when cutter bumps soon.The size of dish (18) is cut in the A influence.Again by formula:

Getting designed ratios N=A/D, in general, is good at 74%-92%.

For example get 74%, the long D=530 of cutter, the cutter heart is apart from A=390; Swath F=D+A=530+390=920, a bit few, it is good a little louder to hope; Heavy swath B=D-A=140, enough.

As another embodiment, get designed ratios N=A/D=92%, the long D=530 of cutter, the cutter heart is apart from A=490; Then the swath F=D+A=530+490=1020 of mower is a little bigger, and is good; Heavy swath B=D-A=40, also available.

If get heavy swath B=D-A≤20, then might leak grass, because of grass be about rolling, and cut dish and overwhelm by askew allowing, just have once in a while sometimes cut less than grass.

Adopt PROE-WILDFIRE software variable picture easily, also available certainly other software.

For example be placed on when cutting dish (58) both sides; Adagio more is difficult for hindering grass, and rubber slab is more convenient for casing.Described protective plate is the material of available hard also.Described protection edges of boards are provided with mobilizable hinge, do not limit one or more or use flexible material, are aided with stop before going too far determinate spacing again, if described protective plate is decontroled can work and change get on to be convenient to case just passable.As extending or improving, described protective plate also can be made as dismountable, puts during work, takes off when not working.In order to prevent trouble before it happens, put prevention first, guarantee that the complete machine of a large amount of shipment all can detect through false pin.Described protective plate also can be used on other place of fuselage, and for example the top of two trailing wheels is protected.As another embodiment, also available acoustic material is processed car load and is not open, but on the top is arranged, or totally-enclosed car type shines in order to retaining, or full sound insulation.The beneficial effect of various noise abatement measures is: not only utilize the impedance of sound-absorbing material different characteristic, reduce reflected sound, and utilize aperture low frequency diffraction shadow zone principle, establish sound barrier and weaken high-frequency noise.It is many that described earplug uses the pre-mould mode earplug, is molded as certain geometry with flexible plastic or soft rubber; Or use the foamed plastics earplug; In the hope of sound insulation property and comfortableness.Described anti-sound cotton is to handle and process through chemical tendering with super glass wool, the most handy 1-3 micron diameter be good; And process the fritter taper, so that fill in one's ear; The cotton sound insulation of anti-sound is more effective than common cotton, and sound-insulation value improves along with the increase of noise frequency, and is more effective to isolated high-frequency noise, uses anti-sound cotton, and contact does not only have obstruction to language, and speech articulation is increased.Described earmuff is the earflap device of earphone class, or uses the music earmuff, increases the enjoyment of work.Described anti-sound head helmet is the motorcycle helmet class, also has the security effect.

The vehicle seat that noise reduction is arranged after described vehicle frame upper center is inclined to one side is also characteristic: vehicle seat is surrounded by thick noise reduction foamed material, and is removable before and after the vehicle seat; Vehicle seat is provided with the people to be connected when sitting down, when the people leaves with regard to obstructed limit protection switch; Or non-contacting human inductor is a sensor, and protective effect is also arranged.There is the receipts grass case (50) of noise reduction at described car rear, is provided with 2 hooks, it is characterized in that S shape, has on the hanger of pin so that hang over 2 of being located at behind the vehicle frame, and pin is to be stuck in versatilely in the S shape, and purpose is can artificial gyration to become reconciled and get to fall grass.

The described single face that two cuttves are driven in the same way is with synchronously, in the workshop, find too tightly, and does not install on the production line fortunately, like korean pine, is prone to leapfrog once in a while again and asynchronous.As improvement, be with (63) good installation synchronously in order to make the single face that drives two cuttves in the same way, referring to Figure 21, be equipped with regulating wheel (63c), described regulating wheel (63c) is with (63) synchronously with single face be that the no flank of tooth contacts, so described regulating wheel is anodontia circle wheel; Regulating wheel is contained on the tensioning support (63d), and tensioning support (63d) is that balance pivot is transferred with fixing bolt (63e) versatilely; Be to infer, made things convenient for installation, and eliminated asynchrony phenomenon by adjusting bolt (63f) on the fixing minor adjustment frame (63h) and setting nut (63g).

As improvement, with acoustic material car load is processed and not to be open, but on the top is arranged, or totally-enclosed car type, or make the large-scale integral car can be beneficial to that retaining shines or full sound insulation; Or with a few bulk splicings.The head fuselage everywhere or whole or piece together all right.Headstock hood shown in Figure 22 (41) and vehicle body (50c) also can or be put in order or assembly.Two major parts before and after for example vehicle body (40c) can be divided into, the back is a bulk of to be divided and can plug together and receive the Shang Dagai of careless case.The head fuselage everywhere or whole or piece together all right; Also mainly be meant anti-noise structure; Like the molded head fuselage and the ceding of Taiwan that is stretched as honeycomb wedge convex concave of steel plate; Or iron plate attaches big of the honeycomb wedge convex concave of injection molded; Join described acoustic material such as foamed material again; Sound-absorbing porous material, foam cement or foamed plastic, or flexible material and film material; Or attach, or directly mold pressing.Or add azoic foaming agent bi-component in mould, in hard outside forming, foam and the structure like portable refrigerator of curing; Or double-deck various big blowing part that is blow molded into large-area honeycomb and wedge appearance convex concave, like head and fuselage, attach thick foamed plastic again.Fully utilize above-mentioned various noise elimination damping materials and be located at mowing table (58) with numerous large-area wedge zones; Headstock hood (41); Vehicle body (50c); The vehicle seat that noise reduction is arranged; The receipts grass case that noise reduction is arranged; Or make the car body of large-scale integral, or add azoic foaming agent bi-component in mould, with form outer hard in foaming and the big part that solidifies such as the structure of portable refrigerator; Or double-deck various big blowing part that is blow molded into large-area honeycomb and wedge appearance convex concave, or attach thick foamed plastic again.To sum up, so the beneficial effect of various noise abatement measures is arranged: not only utilize the impedance of sound-absorbing material different characteristic, reduce reflected sound, and utilize aperture low frequency diffraction shadow zone principle, establish sound barrier and weaken high-frequency noise.The connecting place of the airstrainer (44) that the headstock hood (41) of noise reduction is arranged and eliminate the noise has two car lights (43), should note sticking seam, does not leak very much sound, more will note temperature rise; If with lamp is the LCD luminous tube, then temperature rise is out of question; The airstrainer (44) of eliminating the noise the foamed material of handy empty filter adds the fixing aperture plate of use again, not only empty the filter but also noise reduction.

Science and improvement are constantly to improve with endless.During actual the mowing, meet stone sometimes and hinder cutter; Press the regulation of blade test again, put in blade with steel pipe and cut the district, do not allow fracture, but flexible, this inspires blade that we make improvements from the clutch mower, and the cutter of protection is arranged.Changed repeatedly cutter earlier, changed multiple and cutter again from the relevant part of clutch.Purpose is more for the used part of the mowing-apparatus of the routine that overcomes the hay mower prior art, and rotary inertia is bigger, and power hungry is more, and cutter is to be rigidly connected, and does not have the shortcoming of security protection.A kind of improvement of hay mower cutting mechanism was provided, and was the cutter of not wanting independent tool rest that is used for hay mower, was called the hay mower hay knife of no tool rest, and one can make part reduce, and cost reduces; Two can make weight saving, and consumed power reduces; Three can make it have the function of security protection.But, the tool rest and the accessory of the mower that several moneys have finalized the design are still arranged, hope few the change in the hope of can using, so the tool rest of the end-face friction of several distortion is told about in the application of the tool rest of several on-of pin formulas of following narration again.

Because the mowing-apparatus that noise reduction is arranged that drives the included vehicle frame below of mower of noise reduction measure and hydraulic stepless speed change is arranged, comprise and highly regulate part and mowing part again; Referring to Figure 24; Highly regulate part; Press parallelogram principle; By the preceding dead axle (58a) and the back dead axle 58c that are located on the vehicle frame; And be located at preceding moving axis 58b and the back moving axis 58d that cuts on the dish 58 and be attached thereto moving rod member; And the steel wire rope 58h that supplies pulling usefulness; Sector gear 58g; Ratchet 58f with heighten 55 compositions of handle; It is characterized in that: the described preceding dead axle 58a and back dead axle 58c that is located on the vehicle frame; And to be located at the preceding moving axis 58b that cuts on the dish be four summits of parallelogram with back moving axis 58d; Its corresponding limit is parallel in twos and equal; So, spur steel wire rope 58h through heightening handle 55 in any case, and through sector gear 58g; Ratchet 58f comes to several gears of heightening; The line of preceding dead axle 58a on the vehicle frame and back dead axle 58c, always with cut dish on preceding moving axis 58b be parallel with back moving axis 58d, thereby at the upper and lower translation that has fundamentally guaranteed to cut dish and operate as normal; But still will mix up the length of steel wire rope 58h when practical, and the allotment of sector gear 58g and ratchet 58f.Though wholely cut dish to be close at each gear be parallel, but that front and back have is mobile, be that the engine spindle 51 of ining succession with power belt 61 is the center of circle; What pass to first tool rest through belt 61 is radius and mobile apart from longitudinal projection; And belt 61 also has difference in height, is oblique, fortunately can also use.Can find out have multiple toothly because heighten the described sector gear 58g of gear from Figure 56, existing preferred 10 teeth have 10 grades, for example can cut height at 10-100mm and transfer; Or, divide several shelves preferably by customer requirement by 25-85mm commonly used.Referring to Figure 25, the power of the part of mowing passes to first tool rest from engine spindle 51 through belt 61b, again through being with 23 to pass to second tool rest synchronously, so be convenient to drive hay knife 60 work; As improvement, referring to Figure 33 and Figure 65, described hay knife 60 is provided with two or more wind wings, twines grass in order to cut off, and on described wind wing, is provided with a plurality of cutting edge 60a, and the angle on the two sides of described cutting edge is not the right angle, is preferably less than 60 degree, or acute angle; Further as improving, described hay knife 60 is provided with a plurality of hexagonal holes, or further improves, and described hay knife 60 is provided with a plurality of as honeycomb or like the convex-concave of wedge 29, is noise reduction so be beneficial to the flow through audio frequency of the little air-flow of high speed of cutter of change.

The described mowing graphical designs partly and preferred method of thinking that the mowing-apparatus of noise reduction is arranged is a significant contribution of the present invention.As previously mentioned, the one in front and one in back scheme of two cuttves of original sitting type mower, usefulness be two-sided V-belt, also used three regulating wheels, because of before and after cutter has, make and strengthen before and after cutting dish, cause the complete machine lengthening.Two cuttves of another kind of original sitting type mower, though be not tandem, because of two cuttves are reverse commentaries on classics, usefulness be more expensive two-sided synchronous band, also handy two synchronous tensions are taken turns, this makes the cost increasing.Can find with two cuttves, be one in front and one in back, do not make to cut the increasing of dish front and back, and oppositely do not change, and two-sided synchronous band that need not be more expensive, grass does not leak, and what way does the approach that cutter does not bump use? Answer is yes.Use the diagram optimum seeking method: two point widths of getting bar shaped cutter 20 are diameter D, by the gyroaxis of two cuttves be the belt wheel center (63a, 63b) apart from be A, 2 circles that draw, referring to Figure 53, the anterior part that two circles intersect representes that with the filling hachure width B is exactly the careless heavy swath B that does not leak; Be that diameter is justified again with A, the angle of circumference perseverance is the right angle, hangs down mutually because of establishing two cuttves, and is synchronous rotation, so two two limits that cutter is an angle of circumference can be drawn a plurality of angles of circumference in addition and come preferred.Formula is arranged: B=D-A.Referring again to Figure 54, change A gets belt wheel apart from A=0.618D by optimum seeking method 0.618 method earlier, and mapping strengthens A more gradually, is to the maximum near D; Shown in the figure heavy swath B of maximum and the minimum A when cutter bumps soon.The size that dish 58 is cut in the A influence.Again by formula:

Getting designed ratios N=A/D, in general, is good at 74%-92%.

If get heavy swath B=D-A≤20, then might leak grass, because of grass be about rolling, and cut dish and overwhelm by askew allowing, just have once in a while sometimes cut less than grass.When practical, the gap of cutting interior week of dish and point of a knife is preferably in more than the 3mm.

Because adopt PROE-WILDFIRE software, so variable is drawn easily, also available certainly other software.

Described protective plate profile preferably sufficient shape the bigger waveform in two promptly arranged, so strengthened caution association and artistic image that foot is careful; Described protective plate preferably uses soft but not too soft shore hardness at 65 to 95 materials rubber for example; Polyurethane or polyvinyl chloride are made main sheet material, and its usefulness is to discharge water when putting down work, for example are placed on when cutting dish 18 both sides; Adagio more is difficult for hindering grass, and soft board is more convenient for casing.Described protective plate is the material of available hard also.Described protection edges of boards are provided with mobilizable hinge, do not limit one or more or use flexible material, are aided with stop before going too far determinate spacing again, if described protective plate is decontroled can work and change get on to be convenient to case just passable.As extending or improving, described protective plate also can be made as dismountable, puts during work, takes off when not working.In order to prevent trouble before it happens, put prevention first, guarantee that the complete machine of a large amount of shipment all can detect through false pin.Described protective plate also can be used on other place of fuselage, and for example the top of two trailing wheels is protected.As another embodiment, also available acoustic material is processed car load and is not open, but on the top is arranged, or totally-enclosed car type shines in order to retaining, or full sound insulation.The head fuselage everywhere, all available foamed material, sound-absorbing porous material is like foam cement or foamed plastic, or flexible material and film material, or double-deck blowing part; Or attach, or directly mold pressing, or add azoic foaming agent bi-component in mould and solidify to foam in hard formation outside; Or double-deck various big of being blow molded into large-area honeycomb and wedge appearance convex concave, like head and fuselage.To sum up, so the beneficial effect of various noise abatement measures is arranged: not only utilize the impedance of sound-absorbing material different characteristic, reduce reflected sound, and utilize aperture low frequency diffraction shadow zone principle, establish sound barrier and weaken high-frequency noise.It is many that described earplug uses the pre-mould mode earplug, is molded as certain geometry with flexible plastic or soft rubber; Or use the foamed plastics earplug; So certain sound insulation property and comfortableness are arranged.Again because described anti-sound cotton is to handle and process through chemical tendering with super glass wool, the most handy 1-3 micron diameter be good; And process the fritter taper, so be convenient to fill in one's ear; The cotton sound insulation of anti-sound is more effective than common cotton, and sound-insulation value improves along with the increase of noise frequency, thus more effective to isolated high-frequency noise, use anti-sound cotton, language is got in touch does not only have obstruction, and speech articulation is increased.Described earmuff is the earflap device of earphone class, or uses the music earmuff, so can increase the enjoyment of work.Described anti-sound head helmet is the motorcycle helmet class, so also have the security effect.

Again because the vehicle seat that noise reduction arranged of described vehicle frame upper center after partially is also characteristic: vehicle seat is surrounded by thick noise reduction foamed material, and is removable before and after the vehicle seat; Vehicle seat is provided with the people to be connected when sitting down, when the people leaves with regard to obstructed limit protection switch; Or non-contacting human inductor is a sensor, so protective effect is also arranged.There is the receipts grass case 50 of noise reduction at described car rear, is provided with 2 hooks 17, it is characterized in that S shape, has on the hanger of pin so be convenient to hang over 2 of being located at behind the vehicle frame, and pin is to be stuck in versatilely in the S shape, becomes reconciled with grass and gets so be convenient to artificial gyration.The foregoing single face that two cuttves are driven in the same way is with synchronously, in the workshop, finds too tightly, and does not install on the production line fortunately; Like korean pine, be prone to leapfrog once in a while again and asynchronous.As improvement, be with 63 good installations synchronously in order to make the single face that drives two cuttves in the same way, referring to Figure 21, be equipped with regulating wheel 63c, described regulating wheel 63c and single face contacts with 63 the no flank of tooth synchronously, so described regulating wheel is the anodontia wheel of justifying; Regulating wheel is contained on the tensioning support 63d; Tensioning support 63d is a balance pivot and adjustable with fixing bolt 63e versatilely; So can infer by adjusting bolt 63f on the fixing minor adjustment frame 63h and setting nut 63g, thus made things convenient for installation, and eliminated asynchrony phenomenon.

As improvement, with acoustic material car load is processed and not to be open, but on the top is arranged, or totally-enclosed car type, or make the large-scale integral car can be beneficial to that retaining shines or full sound insulation; Or with a few bulk splicings.The head fuselage everywhere or whole or piece together all right.Headstock hood 41 and vehicle body 50c shown in Figure 60 and Figure 61 can or be put in order or assembly.Two major parts before and after for example vehicle body 50c can be divided into, the back is a bulk of to be divided and can plug together and receive the Shang Dagai of careless case.The head fuselage everywhere or whole or piece together all right anti-noise structure that also mainly is meant; Like the molded head fuselage and the ceding of Taiwan that is stretched as honeycomb wedge convex concave of steel plate; Or iron plate attaches big of the honeycomb wedge convex concave of injection molded; Join described acoustic material such as foamed material again; Sound-absorbing porous material; Foam cement or foamed plastic, or flexible material and film material; Or attach, or directly mold pressing.Or add azoic foaming agent bi-component in mould, in hard outside forming, foam and the structure like portable refrigerator of curing; Or double-deck various big blowing part that is blow molded into large-area honeycomb and wedge appearance convex concave, like head and fuselage, attach thick foamed plastic again.To sum up, so the beneficial effect of various noise abatement measures is arranged: not only utilize the impedance of sound-absorbing material different characteristic, reduce reflected sound, and utilize aperture low frequency diffraction shadow zone principle, establish sound barrier and weaken high-frequency noise.The connecting place of the airstrainer 4 that the headstock hood 1 of noise reduction is arranged and eliminate the noise has two car lights 3, should notice that sticking seam does not leak very much sound, more will note temperature rise; If with lamp is the LCD luminous tube, then temperature rise is out of question; Certainly, the also lamp of available other types.

Science and improvement are constantly to improve with endless.During actual the mowing, meet stone sometimes and hinder cutter; Press the regulation of blade test again, put in blade with steel pipe and cut the district, do not allow fracture, but flexible, this inspires blade that we make improvements from the clutch mower, and the cutter of protection is arranged.Changed repeatedly cutter earlier, changed multiple and cutter again from the relevant part of clutch.Purpose is more for the used part of the mowing-apparatus of the routine that overcomes the hay mower prior art, and rotary inertia is bigger, and power hungry is more, and cutter is to be rigidly connected, and does not have the shortcoming of security protection.A kind of improvement of hay mower cutting mechanism was provided, and was the cutter of not wanting independent tool rest that is used for hay mower, was called the hay mower hay knife of no tool rest, and one can make part reduce, and cost reduces; Two can make weight saving, and consumed power reduces; Three can make it have the function of security protection.But, the tool rest and the accessory of the mower that several moneys have finalized the design are still arranged, hope few the change in the hope of using; So kinds of schemes is arranged; The tool rest that several on-of pin formulas are arranged also has the tool rest of the end-face frictions of many distortion, the existing for example clutch-plate up and down of several end-face frictions.

Referring to Figure 28, be the sketch map of the tool rest assembly of the hay mower used always; Described improved blade is from the tool rest assembly of the band on-of pin of clutch mower; Mainly by blade 60; Tool rest 60a; Power belt wheel 60d, and cutter on-of pin 60c, and elastic ring 60e forms; Blade 60 is contained on the tool rest 60a; Tool rest 60a and power belt wheel 60d are contained on the engine spindle of cotter way, it is characterized in that: described tool rest 60a is provided with the pin-and-hole that can lay the cutter on-of pin, referring to Figure 29; Put into cutter on-of pin 60c, referring to Figure 30 and Figure 31; Elastic ring 60e is housed outward, and the head of described cutter on-of pin 60c is provided with the inclined-plane, or 2 inclined-planes; Referring to Figure 35 and Figure 36, or arcwall face, or the involute face; So be convenient to when torsional moment is excessive, the radial component on the inclined-plane surpasses the 68Nm of regulation, makes it to get out of the way to shrink back; The afterbody of described cutter on-of pin 60c is provided with concave surface, so be convenient to the elastic ring that is installed; Described elastic ring 60e is the closed-coil spring of annular, referring to Figure 38; Certainly, described elastic ring can be used elastic tape; Perhaps, the afterbody of on-of pin is provided with stage clip or torsion spring.Because press careless mower; Referring to Figure 27; Its tool rest 60a2 and power belt wheel are whole aluminium castings; Be contained on the engine spindle of cotter way; So pin-and-hole is located between belt wheel and the tool rest; Put cutter on-of pin 60c earlier, put described elastic ring again, described elastic ring can directly be put into elastic tape; The closed-coil spring of annular or complete, or also available with the long closed-coil spring hook joint of stretched; As long as its footpath and circle footpath are share, please note that hour then power is big with the circle footpath when the silk footpath is big, material and thermal treatment are influential, after the primary election, test fixed output quota more again.Described elastic ring is with elastic tape, and with solid, the cross section is circular; Perhaps use hollowly, the cross section is a tubular; If the afterbody of on-of pin is provided with stage clip or torsion spring, the afterbody of its pin preferably bores an axial hole, and the degree of depth will have half of pin total length, in order to the steel wire that inserts stage clip or torsion spring.Preferably justify in the silk footpath of described elastic ring; Certainly, the also spring of available ribbon, but increase part possibly.

Blade is when mowing for reality from clutch, meets stone by chance and can also allow and operate on and do not hinder cutter, and for the blade test through a kind of regulation; Promptly put in blade and cut the district, do not allow fracture with steel pipe, but flexible; So made improved blade from the clutch mower, and the multiple cutter of protection arranged.Changed repeatedly cutter earlier, changed multiple and cutter again from the relevant part of clutch; Purpose is more for the used part of the mowing-apparatus of the routine that overcomes the hay mower prior art, and rotary inertia is bigger, and power hungry is more, and cutter is to be rigidly connected, and does not have the shortcoming of security protection; The special improvement that a few money hay mower cutting mechanisms are provided again is the tool rest of end-face friction that is used for several distortion of hay mower, reduces in order to make part, and cost reduces; Also in order to make weight saving, consumed power reduces; Make it have the function of security protection; Also change for few; In the hope of can be applicable to the tool rest and the accessory of the mower that several moneys have finalized the design; Several friction plates of the tool rest of the end-face friction that main improvement is distortion; Also do not limit illustrated, so the change of under the precondition that does not depart from the claim flesh and blood, being done still belongs to the rights protection scope of this patent.

Please referring to Figure 39; The mower that the cutter clutch is arranged is with the schematic perspective view that end clutch tool rest is housed; And Figure 44; Be the mower of cutter clutch to be arranged with the sectional arrangement drawing that end clutch tool rest is housed; Mower the tool rest assembly that end clutch be housed of cutter from clutch arranged; Mainly by end clutch tool rest 60a3, tool rest lower sheeting 60b3, clutch-plate 60k under the tool rest; Clutch-plate 60m on the tool rest; And cushion block in cutter 60h and the tool rest, and unillustrated line shaft and cutter fastening bolt form, and it is characterized in that: described have a tool rest of holding clutch; Cushion block in the interior dress tool rest; Refill on line shaft, end clutch tool rest 60a3 is housed from top to bottom successively, clutch-plate 60m on the tool rest; Cutter 60h or other cutter; Clutch-plate 60k under the tool rest, tool rest lower sheeting 60b3, cutter fastening bolt; Referring to Figure 41; The described end face that the tool rest 60a3 of end clutch is arranged; Be provided with groove; The projection that itself and tool rest lower sheeting 60b3 are provided with; When matching; The root of projection is bigger, in any case cutter holder middle and hold again tightly, have the big plane of big plane and tool rest lower sheeting of tool rest of end clutch always gapped; At gap location clutch-plate 60k under the clutch-plate 60m and tool rest is installed on the suitable tool rest again; When usual use; After installing; Its frictional force of rubbing enough makes swivel moving; And when bumping stone or steel pipe unusually; The frictional force of clutch-plate is not enough under last clutch-plate and the tool rest, cutter is skidded, and play cutter from clutch action.In order to compensate contingent manufacturing tolerance and assembling form and position tolerance, not only select the material of clutch-plate under last clutch-plate and the tool rest softlyer, without steel, and use plastics, the most handy PP, polypropylene, or PU, polyurethane, also available certainly other softwood, for example fabric; And clutch-plate under last clutch-plate and the tool rest is carried out various distortion improve, in order to the assembling frictional resistance that is fit to from clutch is arranged; For example, referring to Figure 45 and Figure 46, be mower that the cutter clutch arranged the clutch-plate 60k under the multiple tooth tool rest that has with end clutch tool rest, minimum 2 teeth, maximum 100 teeth, multiple tooth or press circumference uniform distribution and arrange, or press multiple tooth parallel composition convex concave; The best indention of described multiple tooth per tooth that is to say that the per tooth preferably left side is the right angle, and the right is the protrusion piece at obtuse angle, so that be fit to the characteristic of the unidirectional rotation of hay knife; Again for example; Referring to Figure 47; Be that have multiple tooth tool rest on the clutch-plate 60M1 of the mower of cutter clutch with end clutch tool rest arranged; The characteristic that it is multiple tooth; The similar described clutch-plate 60k under the multiple tooth tool rest that has, and also be minimum 2 teeth, maximum 100 teeth; The multiple tooth circumference uniform distribution of pressing is arranged, or by multiple tooth parallel composition convex concave; The best indention of described multiple tooth per tooth that is to say that the per tooth preferably left side is the right angle, and the right is the protrusion piece at obtuse angle, so be beneficial to the characteristic of the unidirectional rotation that is fit to hay knife; But add in addition, that is exactly described multiple tooth, single face still not, and or establish two-sided; This or establish and two-sidedly also be applicable to following and all last clutch-plates.For example, as improvement, referring to Figure 48; Be that the sketch map of the mower of cutter clutch with the tool rest clutch-plate 60m2 that many convex-concaves are arranged of end clutch tool rest arranged, it is provided with big small end, or a plurality of convex-concaves of the different depths are arranged; Its convex-concave or circle, or the side, the different depths are also arranged; Remaking to improving, referring to Figure 49, is that the tool rest clutch-plate 60m3 that many setback arranged of the mower of cutter clutch with end clutch tool rest arranged; Referring to Figure 50, be the multistage flail knife, at least 3 sections on every limit, every section movable riveted joint or the screw loose joint, the first section 60n1 that connects tool rest establishes concave arc, and it is gapped, so be convenient to fine motion; The usefulness of flail knife is to protect from clutch.Cast a brick to attract jade, mention flail knife, not only make more piece, and further make half gentle, like chain, or entirely gentle formula like nylon rope, steel wire rope; Or its combination, nylon encases steel wire rope, or the nylon rope strand is lived steel wire rope.As improvement, described chain is provided with blade; As Figure 41 and gapped cooperation as shown in figure 42 make the tool rest of cutter from clutch, also can change the multiple spacing gap that has into, for example, make a call to two counterbore 60z, to replace groove at the tool rest end face; And establish two banking pin 60Q at the end face of tool rest lower sheeting, or pin, or screw, the effective length of banking pin is slightly larger than the degree of depth of counterbore, to replace projection, please referring to Figure 63.Described banking pin 60Q adopts screw, and also having a benefit is can finely tune spacing gap, is easy to control degree of tightness, but slower in enormous quantities the time.Be not difficult thus to guess; It is a lot of from the concrete refined structure of clutch that end clutch friction makes cutter; To one skilled in the art; Obviously also has the change of many equivalent technologies; But under the precondition that does not depart from the claim flesh and blood, the change of being done still belongs to the rights protection scope of this patent.
