Description

Function wave self-clutched blade riding mower

Technical field

The present invention relates to a kind of hay mower cut the grass on a lawn for places such as garden, park and road side, courts, press the mowing cutter of careless mower, especially function wave self-clutched blade riding mower.

Background technology

Hay mower is widely used in by sometimes mowing from walking the mode sometimes certainly do not walked selected by the hobby of people.Operation pedestrian pulls from walking control crank, by 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 driven by the belt pulley being contained in engine spindle.And engine spindle mowing-apparatus, as Fig. 5. shown in engine spindle mowing-apparatus explosive view, by drive pulley (11), cushion cover (12), key (13), tool rest (14), hay knife (60), large pressure pad circle (16), fastening bolt (17) formed; Generally speaking, tool rest is absolutely necessary.Conventional mowing-apparatus part used is more more expensive; Also heavier, rotary inertia is comparatively large, and power hungry is more; And cutter is rigidly connected, when running into foreign material as water pipe, be very stiff and demanding, there is no security protection.Only there is sword the side of common hilted broadsword and anodontia, its Ren Yi Blunt, and running into cane cuts bad, usually tears; Particularly its end face is circumferentially anodontia, and end face is high at the rotating speed of circumferential location, and cutting function is strong, thus the end face of common hilted broadsword anodontia be very large loss to ablation energy.

Hay mower is widely used in mowing by the mode selected by the hobby of people.Because the mobility of the mower of hand push is poor, and when mowing in practice, due to the anterior narrower swath of mower, so repeat to cut and leak the phenomenon of cutting often have generation, benefit must be gone to cut, it is very arduous that operator's walking is mowed.If with sitting type, be also riding mower, be then seated and feel different than stand, but noise be large.Because riding mower double-pole is synchronous, can not only give hilted broadsword with self-clutched blade.

Silencer is widely used as the silencing equipment of internal combustion engine particularly put-put, is arranged on cylinder cover and is vented doorway, reduce the noise of engine operation process.The limiting value of countries in the world to the noise of various traveling vehicle and mower has relevant regulation, exhaust silencer be exactly such one for reducing the device that exhaust noise is given birth to.The performance evaluation of silencer mainly contains acoustical behavior, the index such as aerodynamic quality and structural behaviour.The considerable part of internal combustion engine belongs to pulsating nature Low Frequency Noise Generator, adopts resistance or impedance is multiple and property and micro-perforated plate muffler more.Mostly the silencer of common internal combustion engine is three-chamber silencer, noise elimination limited use in particular for the silencer of put-put; And must there be larger containment envelope outside, the effect but itself is not eliminated the noise.Moreover its shell temperature rise is higher, hot, affects safety.If add anechoic trap when being improved.The noise reduction of improvement mowing-apparatus and cutter and to subtract consumption also very important.

Artificial foot protection all has related request at standard STD.BSI EN836-ENGL1997 and GB4706.78-2005/IEC60335-2-77:2002.The mowing height of most mower has many gears adjustable, and these must by the strict security regulations controlled to the safety of the pin of operation pedestrian.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 have the mower of shipment, but measured false pin safety by people individually, then all affect mower order.The idea improved allows hay knife be elevated at several millimeters, chassis often.But due to the sheet metal that the cutter local that is elongate strip is folded over, due to tolerance, the reason of form and position tolerance and assembling cumulative errors, the point of a knife at two ends is just difficult to ensure not high not low in a circumferential plane in large quantities of actual production; Just in case occur thing difficulty avoid, but also to guarantee ten thousand none go out safety problem.If with noise attenuation material by mowing table and mower improvement, and improve cutter, be expected the effect receiving security protection and noise abatement.

Phenomenon is cut in the leakage caused in order to avoid the adjacent gap of two cuttves, two cuttves of original sitting type mower, and normally one in front and one in back the strip of two cutter two cuttves hangs down mutually and oppositely turns, so that non-interference; Be two-sided V-belt, also used three regulating wheels, main shortcoming is because of before and after cutter has, and makes to cut before and after dish and strengthens, cause wheel base to strengthen, complete machine lengthens, and the car turning radius becomes large, longitudinal potentiality coefficient of stability is deteriorated, and cost is added, and these are all undesirable.Two cuttves of another kind of original sitting type mower, though be not tandem, because two cuttves oppositely turn, so that non-interference, be double-sided synchronous belt, also handy two synchronous tensions are taken turns, and this makes added cost.

During actual mowing, sometimes meet stone and hinder cutter.Again by the regulation of blade test, with No. 45 steel, diameter 30mm, the seamless steel pipe of wall thickness 3mm, put in blade and cut district, do not allow fracture, but flexible, this grass cutter with self-clutched blade inspiring us to make improvements, also inspires us to make multistage flail knife, and has the cutter of protection.

Summary of the invention

It is constantly improve with endless that science is improved.First changed repeatedly cutter, then change multiple with cutter from the part that clutch is relevant.

Mowing-apparatus in order to the routine overcoming hay mower prior art part used is more, rotary inertia is larger, power hungry is more, and cutter is rigidly connected, there is no the shortcoming of security protection, the invention provides a kind of improvement of hay mower cutting mechanism, it is the cutter of the not independent tool rest for hay mower, be called the hay mower hay knife without tool rest, one can make part reduce ， Zao Price reduces; Two can make weight saving, and consumed power reduces; Three functions that can make it have security protection.Only there is sword side again in order to make up common hilted broadsword and anodontia, its Ren Yi Blunt, and running into cane cuts bad, usually tears, particularly its end face is circumferentially anodontia, and end face is high at the rotating speed of circumferential location, cutting function is strong, therefore the end face of common hilted broadsword anodontia be the shortcoming of very large loss to ablation energy, the present invention is improving for many years, such as material, thermal treatment, mechanism, form, on the basis of the and for example described hay mower hay knife without tool rest, a kind of multi-tooth hey knife for lawn mower is provided especially, the multiple tooth length considerably increasing blade than hilted broadsword, there is many folding swords and have multiple impact cutting angle and slip cutting angle, be conducive to strengthening the careless bar of cutting and straw usefulness, structure is ground at the bottom of the hunchbacked formula of shear blade, it is made to have self-grinding and wear-resisting persistence, and because of multiple tooth sharper than former hilted broadsword and save power consumption.

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

This is the ingenious combination of two class junctures in fact, saves heavy tool rest exactly, and direct punching press can be shaping for what connect on the steel plate of cutter; Or make with welding splicing, be the cutter of not independent tool rest in a word, be that tool rest and cutter are integrated, it be also provided with the key of security protection, the hay mower hay knife without tool rest can be generically and collectively referred to as.

A kind of engine spindle mowing-apparatus, particularly without the hay mower hay knife of tool rest, on the steel plate of cutter, in the riding position region of engine spindle and fastening bolt (17), be provided with pit (2), key (1), keyway (3), as Fig. 5, Fig. 6, Fig. 7, and shown in Fig. 8; It is characterized in that: the internal diameter of described pit (2) equal or tolerance slightly larger than the external diameter of engine spindle, the centre of the bottom of described pit (2) is porose, so that through 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, is from the steel plate of cutter, utilize material and punching press bending and shaping, or to make with welding or glued joint, or use non-steel key, as aluminium key or plastic molding and processing plant's key, and the two sides of its square-section, at least one side, install and sticker in the keyway of engine spindle; The root of described key (1); the namely connecting portion laying the band of position of key at key (1) and the steel plate of cutter and the edge with described pit (2); the crack arrest groove having punching press to bend; correctly to select suitable shear strength; make both to mow by key, again can when encountering water pipe key root overloading and protect.Described correctly select that the method for suitable shear strength is brief and concise to be described below: the root of the key (1) described in manufacture can by the crack arrest channel process of secondary wall.Secondary wall refers to and is connected to panel beating wall on other thin-walled to be counted as the subitem of main wall.The seamed crack arrest groove of crack arrest groove of the root of key, without crack arrest groove, stretch crack arrest groove, rectangle crack arrest groove, Long Circle crack arrest groove, preferably selects seamed crack arrest groove.Suggestion computer bender and PROE, available system acquiescence equation, by Y factor or the K factor; Or with predefined bending table; Or with customization bending table; Material behavior and compensation is considered by system.If the bending table of customization is not assigned to sheet metal component, available following formulae discovery length of run:

L＝(π/2xR+YxT)xθ/90，

In formula, L is the length of run of key; R is the inner radius of key; Y factor this desirable 0.5; T is steel plate thickness, beats edge break and many places are dashed forward convex, can improve the modulus of the mechanics of materials, reduces steel plate thickness; θ is bending angle, can choose between 80-100.Y factor and the K factor are the part constants defined by the position of the neutral bending line of the relative thickness of sheet metal component material.The K factor is the ratio distance (δ) from neutral bending line to inner side radius bend and material thickness (T), and its formula is K=δ/T.Y factor is the ratio between the length of neutral bending line and material thickness (T), and its formula is Y=Kx (pi/2).Can accessing text and the report of HTML sheet metal component and the precision of sheet metal component is set.Two of the method for suitable shear strength is selected to be the methods of facts have proved, at the root of described key (1), the namely connecting portion laying the band of position of key at key (1) and the steel plate of cutter and the edge with described pit (2), nothing wheel is the crack arrest groove having punching press to bend, or to make with welding or glued joint, if facts have proved, still its intensity is too high, material reducing is then taked to cut out method, namely at the root of its key, digging material makes the root portion cross section of key attenuate, to select suitable shear strength.The feature of described keyway (3) is, in the band of position of laying common key (13) at the edge of described pit (2), be provided with wide keyway the same as the keyway of engine spindle, this is for subsequent use for some occasion, such as, when adding woodruff key, such as, when adding spare key.In the middle part of the steel plate of cutter, edge break be beaten and many places are dashed forward convex thinning to strengthen.

Only there is sword side again in order to make up common hilted broadsword and anodontia, its Ren Yi Blunt, and running into cane cuts bad, usually tears; Particularly its end face is circumferentially anodontia, and end face is high at the rotating speed of circumferential location, and cutting function is strong, therefore the end face of common hilted broadsword anodontia be the shortcoming of very large loss to ablation energy, the present invention is improving for many years, such as material, as 65Mn, as 40MnB, thermal treatment is as carbo-nitriding, and mechanism is as hilted broadsword, multitool, stationary knife, cutter of living, form is as flat cutter, jack knife, tulwar, blackout, sprays black moulding, have seat without seat, as as described in the hay mower hay knife without tool rest basis on, provide a kind of multi-tooth hey knife for lawn mower especially, referring to Fig. 8.Described multi-tooth hey knife for lawn mower, primarily of side multiple tooth (24), apical tooth (25), hold multiple tooth (26), wind wing cutting edge (27), and the middle through-hole of cutter hub (18), key (1), pit (2), keyway (3) formed; It is characterized in that, described side multiple tooth (24) is located at cutter hub steel plate side, the namely place of original blade, in the direction of advance of hay knife rotation, with the middle through-hole of cutter hub (18) for reference, multiple tooth is established, at least 1 in a steel plate side, or nearly hundred, such as 16.If tooth is few, preferentially keep to the side namely by the outermost end of rotation round; And in the outermost end by rotation round, be provided with described end multiple tooth (26), at least 1, or reach dozens of, such as 3; Multiple tooth (24) and described end multiple tooth (26) junction in described side, be provided with described apical tooth (25) again.Described side multiple tooth (24), described end multiple tooth (26), and the cross section of the tooth of described apical tooth (25), there is the feature of common tooth, namely the back of a bow that the useful steel plate punched of cross section of each described tooth is stretched, the steel plate of the both sides of the back of a bow has certain angle, the bottom of the back of a bow is polished and namely grinds cutting edge.In addition, described side multiple tooth (24), described end multiple tooth (26), and the common edge feature of the tooth of described apical tooth (25) is, each described tooth has side, has wedge angle; And dual-side or at least one side have cutting edge; Wedge angle or fillet, the angle of the not too point passed through mutually, but general shape to be the head of tooth little and root is thick; The side of described tooth or straight hypotenuse, or curved, arc, or saw thread form, or prominent arc, or arcs of recesses, the side of particularly described tooth is arc, preferably involute shape.The wind wing of cutter is provided with described wind wing cutting edge (27), and it is characterized in that, described wind wing is provided with at least one or more breach, such as 4, and the edge of each breach is also provided with cutting edge (27), twines grass in order to cut-out; The wind wing of cutter maybe can establish the non-round tube hole of wind wing (28), described non-round tube hole at least one, or nearly hundred, such as 6, in order to the booster action having noise reduction.Or wind wing honeycomb is established on the wind wing of cutter; Described wind wing honeycomb at least one, or nearly tens, such as 6, in order to the booster action having noise reduction; Particularly described wind wing honeycomb is protruding, circular cone or pyramid, particularly hexagonal pyramid shape, and there is through hole at middle part, in order to there being good Noise Reduction.The beneficial effect of multi-tooth cutter is: multi-tooth cutter considerably increases the length of blade than hilted broadsword, has many folding swords and has multiple impact cutting angle and slip cutting angle; Material to be cut is flexible, and allow careless phenomenon many during single-blade, single-blade is easily blunt, and fracture torn by a large amount of grass; Sword of rolling over then hugs careless function comparatively by force more, is conducive to the usefulness strengthening the careless bar of cutting and straw, grinds structure at the bottom of the hunchbacked formula of shear blade, makes it have wearability and save power consumption.Wind wing non-circular hole on the wind wing of cutter and wind wing honeycomb, have the booster action of noise reduction.

Improvement is endless.Function wave self-clutched blade riding mower improves on the basis of the riding mower having noise reduction measure and hydraulic stepless speed change, therefore simple to describing of changing last time, and describe detailed to the current function wave self-clutched blade part improved.The mowing-apparatus having noise reduction below vehicle frame included by riding mower, comprises height adjusting part and divides and mowing part, height adjusting part divides, by parallelogram principle, by the front dead axle be located on vehicle frame and rear dead axle, and be located at the front moving axis and the rear moving axis that cut on dish (58) and be attached thereto dynamic rod member, and for the steel wire rope pulled, sector gear, ratchet and heighten handle and formed, described be located at front dead axle on vehicle frame and rear dead axle, and be located at and cut four summits that front moving axis on dish and rear moving axis are parallelogram, its corresponding limit is parallel between two and equal, so, steel wire rope is pulled in any case by heightening handle, and pass through sector gear, ratchet heightens gear to several, front dead axle on vehicle frame and the line of rear dead axle, always parallel with the front moving axis cut on dish with rear moving axis, thus fundamentally ensure that the upper and lower translation that cuts dish and normally working, sector gear has multiple tooth, preferably 10 teeth, has 10 grades, such as, can cut height to adjust at 10-100mm, or by conventional 25-85mm.In the described surrounding of cutting dish (58), be provided with 4 rollers (59), this newly adds: preferably give 4 described roller (59) inflations, use flexible glue material, make it soft, to cushion over the ground and to have auxiliary helping effect to cutting dish (58).The power of part of mowing, from engine spindle (51), passes to the first tool rest through belt (61b), then passes to the second tool rest through Timing Belt (63), to drive hay knife (60) to work; Described hay knife (60) is upper or can be provided with two or more wind wing, and twine grass to cut off, described wind wing is provided with multiple cutting edge, the angle on the two sides of described cutting edge is not right angle, is preferably less than angle or the acute angle of 60 degree; Described hay knife (60) can be provided with multiple hexagonal hole, or described hay knife (60) also can be provided with multiple as honeycomb or the convex-concave as wedge (29), in order to changing the audio frequency and the noise reduction that flow through the high speed Tiny pore of cutter.

Spy provides the graphical designs of the mowing part of the mowing-apparatus of noise reduction and preferred method of thinking, is a significant contribution of the present invention.As previously mentioned, the scheme of one in front and one in back two cuttves of original sitting type mower, be two-sided V-belt, also used three regulating wheels, before and after cutter has, made to cut before and after dish and strengthen, cause complete machine to lengthen.Two cuttves of another kind of original sitting type mower, though be not tandem, because two cuttves oppositely turn, be more expensive double-sided synchronous belt, also handy two synchronous tensions are taken turns, and this makes added cost.Can find with two cuttves, be one in front and one in back, do not make to cut before and after dish to strengthen, and oppositely do not turn, double-sided synchronous belt that need not be more expensive, and grass does not leak, the approach that cutter does not touch, use what way? answer is yes.Use diagram optimum seeking method: two point widths getting strip-shaped cutter (20) are diameter D, are A by the gyroaxis centre-to-centre spacing of two cuttves, draw 2 circles, the front part that two circles intersect represents with filling hachure, and width B is exactly the heavy swath B that grass does not leak; Be that diameter is justified again with A, angle of circumference perseverance is right angle, because establishing two cuttves to hang down mutually, and is synchronous axial system, therefore two cuttves are two limits of angle of circumference; There is formula: B=D-A.Variation A, first by optimum seeking method 0.618 method, gets the cutter heart apart from A=0.618D, mapping, then strengthens A gradually, be to the maximum close to D; Obtain the maximum heavy swath B when cutter touches soon and minimum A.The size of dish (58) is cut in A impact.Again by formula:

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

Such as get 74%, the long D=530 of cutter, the cutter heart is apart from A=390; Swath F=D+A=530+390=920, somewhat few, it is good a little louder to wish; 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, a little bigger, good; Heavy swath B=D-A=40, also can use.Can design further according to this.

If get heavy swath B=D-A≤20, then likely leak grass, because grass is that left and right is shaken, and cut dish overwhelm by askew allowing, sometimes just have once in a while cut less than grass.

Adopt PROE-WILDFIRE software to draw by variable easily, certainly also can use other software.

Summary has anechoic trap (47) forward above the vehicle frame included by the riding mower of noise reduction measure and hydraulic stepless speed change and has the wedge (29) of noise reduction again, as shown in Figure 1, draws engine for seeing clearly to exempt to block to have saved;

Mower, as the term suggests, can mow exactly.No matter be riding mower, still press careless mower, or the hay mower of hand push, all be unable to do without hay knife.Although tool rest form or power transmission mode slightly change, change ten thousand times without leaving the original aim or stand; Every mower, has surpassed moment of torsion just can have safety protection function as long as is equiped with, just can be commonly referred to as the mower of cutter from clutch.

The present invention relates to a kind of riding mower, main improvement purpose makes resultant effect both be conducive to wide cut to mow, and operates comfortable, infinitely variable speeds, be conducive to noise reduction again, environmental protection and safety.Because take multiple noise reduction measure and technical scheme and preferred diagram analysis method, therefore have the riding mower of noise reduction measure and hydraulic stepless speed change, comprise the propons turned to of connection two front-wheels, connect the driven back axle of the band hydraulic stepless speed change of two trailing wheels, the vehicle frame of the band dual fail-safe thick stick above four-wheel, the mowing-apparatus having noise reduction below vehicle frame, engine and the headstock hood 41 having noise reduction and the airstrainer 44 of eliminating the noise of band anechoic trap forward above vehicle frame, the vehicle seat of what vehicle frame upper center was to the rear have noise reduction, and there are receipts grass box 50 and the vehicle body 50c of noise reduction in car rear, and be the personal protection of saddle horse operator and the earplug be furnished with, anti-sound is cotton, and earmuff and all annexes of anti-sound head helmet, its integrated quality increases.Again because there is the propons turned to of connection two front-wheels included by the riding mower of noise reduction measure and hydraulic stepless speed change, be included between two front-wheels 46 by known parallelogram steering mechanism, namely by left cambered axle and the right cambered axle of a connecting rod connection, described left cambered axle upper end is fixed on one end of control lever by a joint arm, the other end of control lever be then connected in steering wheel 48 gear and have on the fluted disc of tapering, therefore be convenient to steering.The tooth of the described fluted disc improved is internal tooth, and particularly inner toothed surface has tapering, and does not originally have; If external tooth, because external tooth easily to be stepped down phenomenon to external tooth, then do not have the external gear of internal gear and steering wheel to join tacit agreement like this; Again because be now improved to tapering or chamfering, just more easily match with oblique tooth.Its tapering is less than 30 degree, preferably 18 degree; Install because fluted disc is level, to connect parallelogram steering mechanism, and the axis of the gear of steering wheel 48 and plumb line are angled, are generally 18 degree, therefore convenient operation; The gap of form and position tolerance will be allocated by fact, and adds grease lubrication.

Function wave self-clutched blade riding mower is also provided with the driven back axle of connection two trailing wheel 46b of noise reduction measure and hydraulic stepless speed change, is conducive to improving gear.If with common mechanical engage a gear back axle, can not infinitely variable speeds, only cost is lower.

Because function wave self-clutched blade riding mower comprises the driven back axle of the band hydraulic stepless speed change of connection two trailing wheel 46b, its inside is provided with two plunger pumps and pilot operated valve device group and multiple gear, described back axle comprises two semiaxis be located between two rear wheels, differential mechanism is provided with between two semiaxis, differential mechanism upwards connects stepless speed changing mechanism and the brake device of the second plunger pump and pilot operated valve device group successively thus, the clutch of the first plunger pump is connected again through pilot operated valve device group, again via the belt 62 of the belt pulley on the turning cylinder of the first plunger pump, transmit the power of engine spindle 51, described differential mechanism comprises a pair axle shaft gear, planetary gear assembly between axle shaft gear, 2 star-wheels of planetary gear assembly, and each tooth number of star is 12, planetary gear assembly is erected on a larger gear wheel, and preferably its number of teeth is 53, described gear wheel engages with intermediate speed pinion, and preferably its number of teeth is 11, described intermediate speed pinion is coaxial and connect firmly with idler gear, and preferably its number of teeth is 48, described idler gear engages with the change-speed gearing of the second plunger pump, and preferably its number of teeth is 13, institute's decelerator that to form and reinforcement, and defines differential mechanism and make turning flexible.The most handy 5 of the plunger of the second described plunger pump, more than the plunger of the first plunger pump, the cylinder diameter of each plunger is just comparatively large, and pretend as oil motor, output torque is just larger.Because the coaxial brake disc being provided with brake device of the change-speed gearing of the second plunger pump, the back axle near brake disc is provided with friction plate, brake bar and spring and form brake device, therefore be convenient to be connected with Hand brake apparatus with the foot brake device in the middle part of vehicle frame; The foot brake device of this car and Hand brake apparatus are actually same set of mechanism.In pilot operated valve device group between the second plunger pump and the first plunger pump, be provided with Shift lever, oil inlet and outlet on the one hand in regulation and control pilot operated valve device group, the angle changing the plunger head inclined-plane of the first plunger pump on the other hand changes output speed, therefore be convenient to the drive shift in the middle part of vehicle frame with retreat shelves and be connected, to form stepless speed changing mechanism; When neutral gear, the angle on the plunger head inclined-plane of the first plunger pump is zero, therefore dallies and no-output; First plunger pump serves the effect of clutch; Drive shift is connected with retrogressing shelves, handles stepless speed changing mechanism, when stepping on drive shift, and the oil-in in the Shift lever regulation and control pilot operated valve device group in the pilot operated valve device group between the second plunger pump and the first plunger pump; Step on deeply, then the speed of a motor vehicle is fast greatly to make oil-in; Step on shallow, oil-feed is young, and then the speed of a motor vehicle is slow, therefore achieves stepless shift; When depressing retrogressing shelves, the Shift lever in the pilot operated valve device group between the second plunger pump and the first plunger pump is reverse, makes the oil inlet and outlet in regulation and control pilot operated valve device group reverse, makes the second plunger pump reversion, drives decelerator below and differential mechanism to reverse, makes it reversing.Because the second plunger pump is actually when oil motor here, it drives change-speed gearing to engage with series of gears, thus driving two semiaxis and trailing wheel 46b.In pilot operated valve device group between the second plunger pump and the first plunger pump, be also provided with parking bar, the interior hydraulic fluid port of regulation and control pilot operated valve device group, when pulling parking position, the D shape bar of the inside of parking bar hinders interior hydraulic fluid port.Inlet valve is provided with to be communicated with outer oil box in described driven back axle inside, therefore convenient lubrication; Also permanent magnet is provided with, the most handy horseshoe magnet in described driven back axle, effective because there being magnetic rotation stream, many places can be located at, therefore be beneficial to and hold each steel and iron parts after permanent wearing and tearing, be mixed into iron filings in oil.

Again because the vehicle frame of the band dual fail-safe thick stick above the four-wheel included by riding mower having noise reduction measure and hydraulic stepless speed change, as shown in Figure 1, bumper 45 is provided with in the front of car, it is characterized in that: described bumper is parallel bars, or three, or more, and every thick stick is that two is curved, the pipe of middle straight or square tube, and have at least two place's supports to support; Parallel bars should more be insured than single; As improvement, described support is not rigidity, but flexible, such as, use spring, or elastomeric material is as rubber or polyurethane, therefore is more conducive to buffering.

Again because there is the mowing-apparatus having noise reduction below the vehicle frame included by the riding mower of noise reduction measure and hydraulic stepless speed change, comprise height adjusting part and divide and mowing part, referring to Figure 24, height adjusting part divides, by parallelogram principle, by being located at front dead axle on vehicle frame (with rear dead axle, and be located at the front moving axis and the rear moving axis that cut on dish 58 and be attached thereto dynamic rod member, and for the steel wire rope pulled, sector gear, ratchet and heighten handle and formed, it is characterized in that: described be located at front dead axle on vehicle frame and rear dead axle, and be located at and cut four summits that front moving axis on dish and rear moving axis are parallelogram, its corresponding limit is parallel between two and equal, so, steel wire rope is pulled in any case by heightening handle, and pass through sector gear, ratchet is fixed several heightens gear, front dead axle on vehicle frame and the line of rear dead axle, always parallel with the front moving axis cut on dish with rear moving axis, thus fundamentally ensure that the upper and lower translation that cuts dish and normally working, but still will mix up the length of steel wire rope time practical, and the allotment gap of sector gear and ratchet.Cut dish to be close at each gear be parallel though whole, but there is movement front and back, is that the engine spindle 51 of ining succession with power belt 61b is for the center of circle, be radius movement through distance longitudinal projection that belt 61b passes to the first tool rest, and belt 61b also has difference in height, be oblique, fortunately can also use.Because the described sector gear heightening gear has multiple tooth, existing preferably 10 teeth, can have 10 grades, such as, can cut height to adjust at 10-100mm; Or by conventional 25-85mm, point several shelves are preferably by customer requirement.Referring to Fig. 1, the power of part of mowing, from engine spindle 51, passes to the first tool rest through belt 61b, then passes to the second tool rest through Timing Belt 63, therefore is convenient to drive hay knife 60 to work.As improvement, described hay knife 60 can being provided with two or more wind wing, twining grass to cut off, described wind wing is provided with multiple cutting edge, the angle on the two sides of described cutting edge is not right angle, is preferably less than 60 degree, or acute angle; Be further used as improvement, described hay knife 60 is provided with multiple hexagonal hole, or further improves, and described hay knife 60 is provided with multiple as honeycomb or the convex-concave as wedge 29, therefore is beneficial to the audio frequency and the noise reduction that change and flow through the high speed Tiny pore of cutter.

What described function wave self-clutched blade riding mower was provided with has the graphical designs of the mowing part of the mowing-apparatus of noise reduction and preferred method of thinking, is a significant contribution of the present invention.As previously mentioned, the scheme of one in front and one in back two cuttves of original sitting type mower, be two-sided V-belt, also used three regulating wheels, before and after cutter has, made to cut before and after dish and strengthen, cause complete machine to lengthen.Two cuttves of another kind of original sitting type mower, though be not tandem, because two cuttves oppositely turn, be more expensive double-sided synchronous belt, also handy two synchronous tensions are taken turns, and this makes added cost.Can find with two cuttves, be one in front and one in back, do not make to cut before and after dish to strengthen, and oppositely do not turn, double-sided synchronous belt that need not be more expensive, and grass does not leak, the approach that cutter does not touch, use what way? answer is yes.By optimum seeking method: two point widths getting strip-shaped cutter 60 are diameter D, are A by the gyroaxis centre-to-centre spacing of two cuttves, draw 2 circles, the front parts that two circles intersect represent with filling hachure, and width B is exactly the heavy swath B that grass does not leak; Be that diameter is justified again with A, angle of circumference perseverance is right angle, because establishing two cuttves to hang down mutually, and is synchronous axial system, therefore two cuttves are two limits of angle of circumference, can separately establish multiple angle of circumference to come preferably.There is formula: B=D-A.Variation A, first gets band wheelspan A=0.618D by optimum seeking method 0.618 method, then strengthens A gradually, be to the maximum close to D; When cutter touches soon, maximum heavy swath B and minimum A.The size of dish 58 is cut in A impact.Again by formula:

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

Such as get 74%, the long D=530 of cutter, the cutter heart is apart from A=390; Swath F=D+A=530+390=920, somewhat few, it is good a little louder to wish; 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, a little bigger, good; Heavy swath B=D-A=40, also can use.

If get heavy swath B=D-A≤20, then likely leak grass, because grass is that left and right is shaken, and cut dish overwhelm by askew allowing, sometimes just have once in a while cut less than grass.Time practical, cut the gap of dish inner circumferential and point of a knife preferably at more than 3mm.

Because adopt PROE-WILDFIRE software, therefore can draw by variable easily, certainly also can use other software.

The cutter heart is apart from A and cut after dish reserves, and in the described surrounding of cutting dish 58, then establishes the installation site of 4 auxiliary wheels 59, the content that the present invention newly adds is: inflate preferably to 4 described rollers 59, use flexible glue material, make it soft, to cushion over the ground and to have auxiliary helping effect to cutting dish 58.Sometimes out-of-flatness, careless uneven time, the feature of described roller 59 is inflations, and material is soft, has the cushioning effect of servo-actuated servo, further improves the flexibility of pressure grass and does not hinder grass roots, thus improves the gear of complete machine.

Again because have the engine of band anechoic trap forward above the vehicle frame included by the riding mower of noise reduction measure and hydraulic stepless speed change and have the car cover of noise reduction, as shown in Figure 1 and Figure 4, draw engine for seeing clearly to exempt to block to have saved; The placement figure of described anechoic trap as shown in Figure 1; Anechoic trap provided by the invention, containing hush tube 47 and tank 42; In the tank 42 described in lower bend immersion of described hush tube 47, therefore there is cooling effect.The effect of described tank kills two birds with one stone, except cooling except, also with water for weight; Because it is located at mower front portion, therefore there is counterweight effect.The water of tank faces the used time and just adds, because this disregards hauled weight; The water added does not add tankful, has had half just.The lower end of the lower bend of described hush tube 47 connects with muffler outlet.The feature of described tank 42 is that its side is provided with through hole, to match with the lower bend of described hush tube 47; Dewatering outlet is provided with bottom it.Described hush tube 47 is by pipe 47a in multistage and brace and form containing the outer tube of multiple wedges 29 array of micropore.Have interior pipe in outer tube, the feature of described interior pipe 47a which is provided with cellular hexagon eyelet, or polygon eyelet, or oval and oval eyelet; And the inner tube length of multistage to be length different and alternate; Such as have one section to be the longer interior pipe of 3/4ths wavelength multiplying factors, then adjacent is the interior pipe of only its quarter-wave multiplying factor.In addition, the distribution of multiple eyelets that described interior pipe is provided with neither be uniform but have density; The position being positioned at 1/4th pipe ranges at the middle part on one section of pipe of 3/4ths wavelength multiplying factors is closeer eyelet, the pipe of remaining part is the eyelet comparatively dredged; And the feature of its eyelet is hexagon eyelet or many prismatics; The feature of the interior pipe of the quarter-wave multiplying factor of described band eyelet is, the distribution of the multiple eyelets which is provided with is not uniform but has density; The position being positioned at 3/8ths pipe ranges at the middle part on this section of pipe is closeer eyelet, the pipe of remaining part is the eyelet comparatively dredged.Described eyelet is polygonal, preferably hexagonal; As improvement, or the feature of its eyelet is many prismatics, or six prismatics, or have the polygonal of a fabrication flange; Or the feature of its eyelet is the described wedge 29 having micropore, therefore there is quarter-wave effect and dilatational wave effect and honeycomb effect.On the face of described outer tube, many stamping projections can be provided with, in multi-prism taper and multiaspect cone-shaped, particularly hexagonal pyramid shape, is called wedge 29; The feature of described wedge is, it is hexagon from the root of the punching press of metallic plate, and reduce from root to top, roughly its breadth depth ratio is one to one, or to one to one five.And the top of the wedge of each described hexagonal pyramid shape on the face of described hush tube is provided with micropore, and its approximate diameter is advisable at 0.1 to 0.5 millimeter.In described pipe 47a face on, as improvement, or its eyelet also can change and is set to many stamping projections, in multi-prism taper and multiaspect cone-shaped, particularly hexagonal pyramid shape, also can be described as wedge, but its breadth depth ratio is One to naught point eight, or to one. four to one.The how stupefied structure of many wedges composition wedge, it is that the hexagonal of honeycomb is polygonal in the arrangement in each face, or random, or oval, Long Circle, or irregular convex-concave shape; In hush tube or partly can be filled with the nonmetallic materials of metallic fiber or heatproof; Or the sound-absorbing material that partly can be filled with resistance to middle temperature is as sound-absorbing porous material, or flexible material and film material.Or attach, or directly mold pressing, or add azoic foaming agent bi-component in mould make outer hard in and solidify.Described porous material is as fiber-like, and foam class, particulate species, alone good, more or less mixing application is good.Also usable fibers class is as rock wool, or glass fiber, or mineral wool particularly super glass wool; Or use foam class, by warmware, place wants fireproof; Or by particulate species as expanded perlite, porous clay brick, and the fabric of heatproof, felt is filled or is attached; Therefore be beneficial to improved performance index, and make comprehensive composition reach the good object of noise reduction.Multiple material has complementary low-and high-frequency sound absorption usefulness.Many wedges, have added area of dissipation; Particularly many wedges having micropore, not only have the micropore effect of noise reduction, and have the latent effectiveness of hypereccrisia gas-liquid.As extending, many wedges also can reverse-drawing namely outwardly to add area of dissipation.The pad not only made heat insulating mattress but also make beam also can be assembled between silencer and engine.Also the pad not only made heat insulating mattress but also make beam can be assembled between the outlet and described hush tube 47 of silencer.Anechoic trap provided by the invention, is provided with numerous large-area wedge regions, containing numerous wedges having micropore, has wedge to hinder and falls effect and micropore effect.The beneficial effect that anechoic trap provided by the invention causes is: increase the combination property of soundproof effect and lifting silencer as insertion loss, sound transmission loss, noise abatement amount and attenuation, and cooling.A kind of inventive concept is being hovered as ghost: if with thick soft foamed plastics, or as improving, fully utilize above-mentioned various silencing vibration-damping material and with numerous large-area wedge regions, be located at mowing table 58, and mower many places are as headstock hood 41, as vehicle body 50c, also has the vehicle seat having noise reduction that vehicle frame upper center is to the rear, and there is the receipts grass box of noise reduction at car rear, so there is the effect of security protection and noise abatement.In addition, be the personal protection of saddle horse operator, annex of the present invention adds is furnished with earplug, and anti-sound is cotton, earmuff and anti-sound head helmet.Also in the middle part of mower, both sides are provided with the artificial foot protection plate containing turning joint.The artificial foot protection plate containing turning joint that described both sides in the middle part of mower are provided with is made up of protective plate and turning joint; It is characterized in that described protective plate is the sound absorption material selected, and left, right each one; But when sometimes will to lay side Lysimachia sikokiana plate on right side, just an on the left side lays artificial foot protection plate; Namely the waveform having two bigger of described protective plate profile preferably foot-shape, can with reference to figure 3, therefore enhances warning association and artistic image that foot is careful; Described protective plate preferably uses more soft but not too soft shore hardness at 65 to 95 materials such as rubber, main sheet material made by polyurethane or polyvinyl chloride, and its usefulness discharges water when putting down work, such as, be placed on when cutting dish 18 both sides, adagio more not easily hinders grass, and soft board is more convenient for casing.Described protective plate also can use the material of hard.Described protection edges of boards are provided with mobilizable hinge, do not limit one or more or with flexible material, then are aided with stop before going too far determinate spacing, if described protective plate can be made to decontrol can work and turn get on to be convenient to case just passable.As extending or improving, described protective plate also can be set to dismountable, puts, take off when not working during work.In order to prevent trouble before it happens, put prevention first, guarantee that the complete machine of a large amount of shipment all detects by false pin.Described protective plate also can be used on fuselage, and other is local, and such as the top of two trailing wheels is protected.As another embodiment, also available acoustic material makes car load is not open, but on have top or totally-enclosed car type, to shine in order to gear, or full sound insulation.Head fuselage everywhere, all available foamed material, sound-absorbing porous material, as foam cement or foamed plastic, or flexible material and film material, or the blowing part of bilayer; Or attach, or directly mold pressing, or add azoic foaming agent in mould bi-component with formed outer hard in foam and solidify; Or various large that is blow molded into large-area honeycomb and wedge sample convex concave of bilayer, as head and fuselage.To sum up, therefore there is the beneficial effect of various noise reducing efforts: not only utilize the characteristic impedance that sound-absorbing material is different, reduce reflected sound, and utilize aperture low frequency diffraction shadow zone principle, if sound barrier weakens high-frequency noise.Described earplug pre-mould mode earplug is many, is molded as certain geometry with flexible plastic or soft rubber; Or use foamed plastics earplug; Therefore have certain sound insulation property and comfortableness.Again because described anti-sound cotton be make through Chemical softnessprocess with super glass wool, the most handy 1-3 micron diameter be good; And make fritter taper, therefore be convenient to plug in one's ear; The sound insulation of anti-sound cotton is more effective than common cotton, and sound-insulation value improves along with the increase of noise frequency, therefore more effective to isolated high-frequency noise, uses anti-sound cotton, not only without prejudice to linguistic relationships, and increases to speech articulation.Described earmuff is the ear protection device of earphone class, or uses music earmuff, therefore can increase the enjoyment of work.Described anti-sound head helmet is motorcycle helmet class, therefore also has security effect.

Again because described vehicle frame upper center to the rear have the vehicle seat of noise reduction also characteristic: vehicle seat is surrounded by thick noise reduction foamed material, removable before and after vehicle seat; Vehicle seat is provided with when people sits down and connects, limit protection switch just obstructed when people leaves; Or non-contacting human inductor and sensor, therefore also there is protective effect.There is the receipts grass box 50 of noise reduction at described car rear, is provided with 2 hooks, it is characterized in that S shape, therefore is convenient to hang over after being located at vehicle frame 2 and has on the hanger of pin, and pin is stuck in actively in S shape, therefore is convenient to artificial gyration and becomes reconciled get to fall grass.Make the one side Timing Belt that two cuttves drive in the same way foregoing, find too tight in workshop, and badly to install on a production line; As korean pine, easily leapfrog and asynchronous once in a while again.In order to make the good installation of one side Timing Belt 63 driving two cuttves in the same way, added regulating wheel, described regulating wheel and one side Timing Belt 63 are without face, so described regulating wheel is anodontia circle wheel; Regulating wheel is contained on tensioning support, tensioning support actively with fixing bolt for balance pivot, by the adjusting bolt on the minor adjustment frame fixed with set up nut and can estimate, therefore facilitate installation, and eliminate asynchrony phenomenon.

Hereby provide, with acoustic material, car load being made is not open, but on have top or totally-enclosed car type, or make large-scale integral car, gear can be beneficial to and shine or full sound insulation; Or splice by several bulk.Head fuselage everywhere or whole or spell all right.Headstock hood 41 and vehicle body 50c, can whole or spell.Such as vehicle body 50c can be divided into front and back two major parts, and rear a bulk of dividing can plug together and do to receive the Shang great Gai of grass box.Head fuselage everywhere or whole or spell all right anti-noise structure that also mainly to refer to, as steel plate is molded the head fuselage and the ceding of Taiwan being stretched as honeycomb wedge convex concave, or iron plate attaches large of the honeycomb wedge convex concave of injection molded, join described acoustic material again as foamed material, 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, to form the structure as portable refrigerator of outer hard interior foaming and solidification; Or the various large blowing part being blow molded into large-area honeycomb and wedge sample convex concave of bilayer, as head and fuselage, then attach thick foamed plastic.To sum up, therefore there is the beneficial effect of various noise reducing efforts: not only utilize the characteristic impedance that sound-absorbing material is different, reduce reflected sound, and utilize aperture low frequency diffraction shadow zone principle, if sound barrier weakens high-frequency noise.There is the connecting place of the airstrainer 4 of the headstock hood 1 of noise reduction and noise elimination to have two car lights 3, should notice that sticky seam does not leak sound very much, more will note temperature rise; If be LCD luminous tube with lamp, then temperature rise is out of question; Certainly, also can the lamp of other classes of temporary.

The present invention is constantly perfect on many bases in advance.During actual mowing, sometimes meet stone and hinder cutter; Again by the regulation of blade test, put in blade with steel pipe and cut district, do not allow fracture, but flexible, this grass cutter with self-clutched blade inspiring us to make improvements, and the cutter having protection.First changed repeatedly cutter, then change multiple with cutter from the part that clutch is relevant.Object is that the mowing-apparatus part used of routine in order to overcome hay mower prior art is more, and rotary inertia is comparatively large, and power hungry is more, and cutter is rigidly connected, and does not have the shortcoming of security protection.Thered is provided a kind of improvement of hay mower cutting mechanism, be the cutter of the not independent tool rest for hay mower, be called the hay mower hay knife without tool rest, one can make part reduce, and cost reduces; Two can make weight saving, and consumed power reduces; Three functions that can make it have security protection.But the tool rest of the mower still having a few money to shape and accessory, wish few change in the hope of applying, so there is kinds of schemes, have the tool rest of several clutch pin, also have the tool rest of the end-face friction of many distortion.The clutch-plate up and down of several end-face friction, particularly many kinds of function ripple clutch-plate, can be used for multiple tool rest, as the tool rest of end-face friction; Function wave clutch-plate, not only can be used for the clutch of function wave cutter and drive machine, can also be used for the clutch of multiple electronic product.

Because the hay mower tool rest assembly of the band on-of pin of the grass cutter with self-clutched blade of described improvement, primarily of blade 60, tool rest 60a, power belt wheel 60d, and cutter on-of pin 60c, and elastic ring 60e formed, blade 60 is contained on tool rest 60a, tool rest 60a and power belt wheel 60d is contained on the engine spindle of cotter way, it is characterized in that: described tool rest 60a is provided with the pin-and-hole can laying cutter on-of pin, referring to Figure 29; Pin-and-hole can put into cutter on-of pin 60c, referring to Figure 11; Exterior flexible circle 60e, can referring to Figure 15; The head of described cutter on-of pin 60c is provided with inclined-plane, or 2 inclined-planes, referring to Figure 11 and Figure 14, or arcwall face, or involute face, so that when torsional moment is excessive, the radial component on inclined-plane exceedes 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, to be installed elastic ring; Described elastic ring 60e is the closed-coil spring of annular; Certainly, described elastic ring also can use elastic tape; Or the afterbody of on-of pin is provided with stage clip or torsion spring.Because pushing riding dual-purpose mower and the careless mower of pressure, referring to Figure 14, its tool rest 60a2 and power belt wheel are overall aluminium castings, be contained on the engine spindle of cotter way, so pin-and-hole is located between belt wheel and tool rest, put cutter on-of pin 60c again, then put described elastic ring, described elastic ring elastic tape can directly be put into; The closed-coil spring or complete of annular, or also can use with the closed-coil spring hook joint that stretched is long; As long as make its string diameter and circle footpath share, please note when string diameter is large and circle footpath hour then power greatly, material and thermal treatment have impact, after primary election, then test, then fixed output quota.Described elastic ring elastic tape, with solid, cross section is circular; Or with hollow, cross section is 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 the half of pin total length, in order to the steel wire inserting stage clip or torsion spring.The string diameter of described elastic ring preferably circle; Certainly, the spring of bandlet shape can also be used.

Self-clutched blade be in order to reality mow time, meet stone by chance and can also allow and operate on and do not hinder cutter, and test in order to the blade by a kind of regulation, namely put in blade with steel pipe and cut district, do not allow fracture, but flexible, so made the grass cutter with self-clutched blade improved, and there is the multiple cutter of protection.First changed repeatedly cutter, then change multiple with cutter from the part that clutch is relevant; Object is that the mowing-apparatus part used of routine in order to overcome hay mower prior art is more, and rotary inertia is comparatively large, and power hungry is more, and cutter is rigidly connected, and does not have the shortcoming of security protection; Spy reoffers the improvement of a few money hay mower cutting mechanism, is the tool rest of the end-face friction of several distortion, mainly tells about several friction plates of the tool rest of the end-face friction of distortion.Emphasis is several function wave friction plates of end-face friction improved, and not only can be used for the clutch of the cutter of various tool rest, and the clutch of powered pulley for riding mower, therefore solves the difficult problem driving the synchronous bad clutch of double-pole.

Because as several hay mowers end clutch tool rest that cutter is housed of Figure 18 and Figure 19, use multiple friction clutch disc.There is cutter from the mower tool rest assembly that end clutch is housed of clutch, primarily of end clutch tool rest 60a3, tool rest lower sheeting 60b3, clutch-plate 60k under tool rest, clutch-plate 60m on tool rest, and cushion block in cutter 60h and tool rest, and unillustrated line shaft and cutter fastening bolt formed, the described tool rest having end clutch, cushion block in in-built tool rest, refill on line shaft, end clutch tool rest 60a3 is housed from top to bottom successively, clutch-plate 60m on tool rest, cutter 60h or other cutter, clutch-plate 60k under tool rest, tool rest lower sheeting 60b3, cutter fastening bolt; The described end face having the tool rest 60a3 of end clutch, be provided with groove, the projection that itself and tool rest lower sheeting 60b3 are provided with, when matching, the root of projection is larger, therefore in any case cutter be clipped in the middle and hold again tight, there are the large plane of tool rest of end clutch and the large plane of tool rest lower sheeting always to have gap; Or establish counterbore to replace groove at the end face of tool rest, and establish banking pin to replace projection at tool rest lower sheeting, need two to more than, as long as the effective length of banking pin is greater than the degree of depth of counterbore, have gap, or repair follow closely or cushioning that gap is suitable for is good.Then at gap location, clutch-plate 60k under clutch-plate 60m and tool rest is installed on suitable tool rest, when usually using, after installing, its frictional force enough makes swivel move, therefore when extremely touching stone or steel pipe, under upper clutch-plate and tool rest, the frictional force of clutch-plate is enough, cutter is skidded, and plays cutter from clutch action.In order to compensate contingent manufacturing tolerance and assembling form and position tolerance, not only the material of clutch-plate under upper clutch-plate and tool rest is selected softer, without steel, and with plastics, the most handy PP, polypropylene, or PU, polyurethane, also can use other softwood certainly, such as fabric; Or plastics are mixed with fabric; Or establish pressure sensing sheet; Or establish function friction plate; And clutch-plate under upper clutch-plate and tool rest is carried out various distortion improvement, in order to there being the assembling frictional resistance be applicable to from clutch; Such as, referring to Figure 20 and Figure 21, be have the mower of cutter clutch to hold clutch tool rest have clutch-plate 60k under multiple tooth tool rest, minimum 2 teeth, maximum 100 teeth, multiple tooth or circumferentially uniform arrangement, or by multiple tooth parallel composition convex concave;
