Background technology

Hay mower is widely used in mowing in the way of selected by the hobby of people.Due to the hay mover of hand push Mobility is poor, and in putting into practice when mowing, due to the narrower swath in hay mover front portion, so repeating to cut and leak the phenomenon cut often has Occur, benefit must be gone to cut, it is very arduous that operator's walking, which is mowed,.If with sitting type, riding mower is also, then is seated than station And feel different, but noise is big.If the prominent position that disseats of people, is protected for original 3 seconds；Dan has rushed 9 meters or danger Jiu the meter per seconds of Suan 3.

Silencer is widely used as the silencing equipment of internal combustion engine particularly put-put, is arranged on cylinder cover Valve port, to reduce the noise of engine operation process.Pole of the countries in the world to various traveling vehicles and the noise of hay mover Limit value has the regulation of correlation, and exhaust silencer is exactly such a device of life for reduction exhaust noise.The property of silencer Can evaluate mainly has acoustical behavior, the index such as aerodynamic quality and structural behaviour.The considerable part category pulsating nature of internal combustion engine is low Frequency noise source, more using resistance or impedance is answered and property and micro-perforated plate muffler.The silencer of common internal combustion engine in particular for The silencer of put-put is three-chamber silencer mostly, and noise elimination effect is limited；And outside must have larger containment envelope, But itself is acted on without noise elimination.It is hot moreover its shell temperature rise is higher, influence safety.If plus anechoic trap ought have improvement. It is easier said than done to solve global hard nut to crack.How this kind of product is further improved, associates the present inventor and once existed Foreign countries are particularly related to lifetime experience of manufacture in Switzerland as senior engineer SENIOR ENGINEER, are improved special kneading, then Be aided with invention research and development to be expected to make product attain a yet higher goal, just like silkworm in spring to dead silk not to the utmost, the mankind pursue invention perfection be forever without End, can noise reduction sound-deadening, the present invention just arise at the historic moment.

Artificial foot protection is in standard STD.BSI EN 836-ENGL 1997 and GB 4706.78-2005/IEC 60335-2- 77：2002 have related request.The mowing height of most hay movers is that have that more gears are adjustable, this peace to operating the pin of pedestrian Entirely must be by the security regulations strictly controlled.This is typically to do what prosthetic foot was tested.But the prosthetic foot test location of palpus test daily is more, multiple Lid product quantity is very little.So that there is the hay mover of shipment, prosthetic foot safety is measured but by people individually, then all influences to cut Careless machine order.Improved idea often allows hay knife to be elevated at several millimeters of chassis.But because cutter is the part of elongate strip The sheet metal being folded over, due to tolerance, the reason for form and position tolerance and assembling cumulative errors, the point of a knife at both ends is in large quantities of actual productions In be difficult to ensure it is not high not low in a circumferential plane；Just in case occur thing difficulty avoid, but also to ensure ten thousand none go out Safety problem.The side discharge of hay mower is easy for Lysimachia sikokiana, but side Lysimachia sikokiana lid will in addition be collected and want the used time to call in installation again； And because be quickly to hang on hook temporarily, usually it be dropped or touch down when mowing, it is seen that dangerous hay knife in straw outlet； A variety of inventive concepts are being hovered such as ghost：If with thick soft foamed plastics by mowing table and the outsourcing of hay mover many places it, can The effect for receiving security protection and noise abatement is hoped, is really that my observations may contain a grain of truth.It is again to use safety precautions when safer more.

In order to avoid phenomenon is cut in the leakage caused by the adjacent gap of two knives, two of original sitting type hay mover Knife, typically one in front and one in back.Figure 23 is refer to, this is the transmission signal of one in front and one in back two knives of original sitting type hay mover Scheme, in figure, 23a is the belt pulley on the axle of the first knife, and 23b is the belt pulley on the axle of the second knife, and 11 be the belt of engine Wheel.The strip of two knives is mutually to hang down and reversely turn, so as to non-interference；It is two-sided V-belt, has also used three tensionings Wheel, more primary disadvantage is that before and after having because of knife, make to cut the front and rear increasing of disk, cause wheel base to increase, complete machine lengthens, car revolution half Footpath becomes big, and longitudinal potentiality coefficient of stability is deteriorated, and cost is added, and these are all undesirable.Another original sitting type Two knives of hay mover, though it is not one in front and one in back, referring to Figure 24, because two knives reversely turn, so as to non-interference, to be Double-sided synchronous belt, also handy two synchronous tension wheels, this causes added cost.If driven without tensioning wheel and with ordinary straps, It is that can reduce cost；But without tensioning, belt is just too loose without handy, unless primary and secondary belt wheel spacing further significantly shortens；It is double Will there is unavoidable ground between hay knife is cut rate and is cut with leakproof again, and multi-purpose double hay knives are smaller than knife diameter；So require double Hay knife reversely rotates, and requires that double hay knives are staggeredly provided with certain phase, and this requires the mutual invariablenes turning speed of double hay knives, just Use synchronous cog belt；But problem is that not only tension structure is complicated, synchronous cog belt and wheel cost improve, more undesirable be because Double hay knives reversely rotate and can not be provided with the rear Lysimachia sikokiana and side Lysimachia sikokiana of wide cut simultaneously, and in the market objectively needs have two simultaneously Go out the four-wheel hay mower of careless outlet after individual or prevent misunderstanding operation from opening the lawn of side Lysimachia sikokiana lid and cutting with manual locking Careless machine；Or the left fan door-plate of tool and the hay mower of right wing door-plate and the side Lysimachia sikokiana lid that shrinks；Or door-plate is led to left and right Rail slips off and the hay mower with side Lysimachia sikokiana lid；Or tool interlocks to be locked from misunderstanding operation and opens the lawn of side Lysimachia sikokiana lid and cut Careless machine side generation, in the hope of meeting the international new safety of 2017, in favor of products export.Under the above promotion of many reforms, wish Product is set to attain a yet higher goal, innovation design is hovered such as ghost for a long time, with Switzerland's senior engineer's SENI.ENGI. lifetime experiences And international co-operation, it is thousand worries and good fortune has one, then the present invention just arises at the historic moment, be exactly people what is meant by hard nut to crack Often ignore and fail to give attention to.World-famous puzzle is thought in solution, and innovation is thought wadding and pushed up accumulateing：Noise reduction sound-deadening grass-winding proof, say and easily do hardly possible, Appearance is told explanation just, and examination sends inner feelings more than invention, do not expect and leave behind a good reputation behind, merely cast a brick to attract jade.

The content of the invention

The present invention relates to one kind to be used for by garden, park and road, and the hay mover that physical culture place cuts the grass on a lawn is main to improve Purpose does not add safety circuit protection measures still, resultant effect is not only improved mowing, operation is comfortable, variable speed, has again Beneficial to noise reduction, environmental protection and safety, and be in order to reduce cost；But without tensioning, belt is just too loose without handy, except non-master Secondary belt wheel spacing further significantly shortens；Will there is unavoidable ground between double hay knives is cut rate and is cut with leakproof again, uses double hay knives It is smaller than knife diameter；So require double hay knives to reversely rotate, and require that double hay knives are staggeredly provided with certain phase, this is just It is required that double mutual invariablenes turning speeds of hay knife are it is necessary to using synchronous cog belt；But problem is that not only tension structure is complicated, synchronous cog belt And wheel cost improves, more undesirable can not be arranged in the rear Lysimachia sikokiana provided with wide cut and side simultaneously because double hay knives reversely rotate Grass, in the market objectively needs a kind of while there is the four-wheel hay mower for going out careless outlet after two to emerge, in the hope of not blocking up Grass.

The technical scheme adopted by the invention to solve the technical problem is that again to there is the hay mover of safety circuit protection measures And safeguard protection have the hay mover of noise reduction pioneer and constantly improve and perfect driven without tensioning wheel ordinary straps it is tilting double in the same direction With the four-wheel hay mower for going out careless outlet after two while the double careless wide cut hay mover of hay knife is innovated for reference In the hope of not stifled grass.

Have the riding mower of safety circuit protection measures, be add safety circuit protection measures have noise reduction measure and liquid Press the riding mower of variable speed, including safety circuit protection measures, and the propons turned to of two front-wheels of connection, connection Two trailing wheels drive back axle with hydraulic stepless speed change, the vehicle frame with dual fail-safe thick stick above four-wheel, having below vehicle frame The mowing-apparatus of noise reduction, the forward engine with anechoic trap in vehicle frame top and the headstock hood (1) for having noise reduction and the air eliminated the noise There is the receipts grass box of noise reduction at screen pack (4), the vehicle frame upper center vehicle seat for having noise reduction to the rear, and car rear, and also saddle horse is grasped Author's personal protection annex includes earplug, anti-sound cotton, earmuff and anti-sound head helmet；It is characterized in that：In the headstock hood 1 for having noise reduction and disappear The connecting place of the airstrainer 4 of sound, provided with two car lights 3, both it is noted that viscous seam not leak very much sound, more it is noted that temperature rise, if It is LED with lamp, then temperature rise is out of question；Lamp is mentioned it is necessary to mention circuit；, must on riding mower for safety Install safety circuit protection measures additional, described safety circuit, mainly by single board computer and instrument plug-in unit (C4), engine plug-in unit (C1), Expansion plugin (C5), ignition switch (C2), battery (B1), DC relay (C3), power output PTO switches (C6), electromagnetism Clutch (C7), starter (ST), hang case buzzer (U1), full careless buzzer (U2), the first insurance (F1), the second insurance (F2), head lamp switch (S0), left headlamp (L1), right headlamp (L2), parking switch (S1), N gear switch (S2), seat is opened Close (S3), hang grass cutting collection box switch (S4), full careless alarm switch (S5) is formed, described left headlamp (L1) and right headlamp (L2), respectively by multiple, such as 4 light emitting diodes are in series, and can also power up resistance；Or respectively by multiple light emitting diode strings simultaneously Connection, for example, 4 string 4 and i.e. respectively combined by 16 pipes, moreover, preferably multitube arcuately covering of the fan arrange, with profit expand angular field of view； Described seat switch (S3), has now made unconventional design of new design；Because original seat switch, although seat not by Seat switch is to disconnect when sitting down, and can just be started after driver sits down；After if driver leaves seat, there is the list of 3-5 seconds The flame-out control of trigger delay, this, which is sounded, seems very safe, and actually this is not so；Original seat switch is individual long-term it is difficult to solution Hard nut to crack certainly, because when actual job, meadow is jolted, hip are shakes, and seat is upper and lower, seat switch It is that suddenly logical neglect is broken, particularly when driver falls accidentally, has the flame-out control of unit delay of 3-5 seconds, after waiting the 3-5 seconds It is flame-out；The hay mover speed of travel both makes to take most at a slow speed one meter per second, also to go out 3-5 rice, or ten at 3.6 to 15 kilometers/hour Several meters could far stop, it is conceivable that this is to the trick fallen or barrier how it feels；Although practise under normal conditions Think often using the flame-out control of unit delay for there are the 3-5 seconds, but in order to prevent unsafe hidden danger, it is necessary to newly conceive The reliable and less expensive seat switch of non-conventional design, described seat switch must be safe, when seat is shaken up and down When amplitude is very big, seat switch can not neglect logical neglect and break, and taking seriously will disconnect at once when disconnecting in 0.1 second；The present invention The seat switch of offer solves this hard nut to crack；Referring to Figure 28, described seat switch (S3),

Embodiment

Adopt the technical scheme that to there is the hay mover of safety circuit protection measures and safeguard protection to have the mowing of noise reduction Machine continuous improve and perfect for pioneer drives the tilting double careless wide cut hay mover of double hay knives in the same direction without tensioning wheel ordinary straps On the basis of update perfect several schemes：Or prevent misunderstanding operation from opening the lawn of side Lysimachia sikokiana lid and cutting with manual locking Careless machine；Or the left fan door-plate of tool and the hay mower of right wing door-plate and the side Lysimachia sikokiana lid that shrinks；Or door-plate is led to left and right Rail slips off and the hay mower with side Lysimachia sikokiana lid；Or tool interlocks to be locked from misunderstanding operation and opens the lawn of side Lysimachia sikokiana lid and cut Careless machine；It is each has something to recommend him.

There is the riding mower of safety circuit protection measures, be that existing security circuit has noise reduction measure and hydraulic stepless to become again The riding mower of speed, in addition to safety circuit protection measures, include the propons turned to of two front-wheels of connection, connection two Individual trailing wheel drives back axle with hydraulic stepless speed change, the vehicle frame with dual fail-safe thick stick above four-wheel, has drop below vehicle frame The mowing-apparatus made an uproar, the forward engine with anechoic trap in vehicle frame top and the headstock hood 1 for having noise reduction and the air mistake eliminated the noise There are the receipts grass box 10 and vehicle body 10c of noise reduction in filter screen 4, the vehicle frame upper center vehicle seat for having noise reduction to the rear, and car rear；And The earplug being furnished with for the personal protection of saddle horse operator, anti-sound cotton, earmuff and the anti-all annexes of sound head helmet, to improve comprehensive product Matter.The propons turned to of two front-wheels of connection included by described riding mower, passes through between two front-wheels 6 Known parallelogram steering mechanism, i.e., the left cambered axle and right cambered axle, the left cambered axle upper end connected by a connecting rod pass through One joint arm is fixed on one end of control-rod, and the other end of control-rod is then connected in gear and tapered tooth with steering wheel 8 On disk 8a, therefore it is easy to manipulate direction.As shown in Fig. 9, Figure 10, Figure 13 and Figure 15, described fluted disc 8a is characterized in：Its fluted disc 8a tooth is internal tooth, and particularly inner toothed surface is tapered, and does not have originally；If external tooth, because external tooth tends to have resigning to external tooth now As then matching somebody with somebody so tacit without the external gear of internal gear and steering wheel；Again because being now improved to tapered or chamfering, just it is more easy to Match with oblique tooth.Its taper is less than 30 degree, preferably 18 degree；Because fluted disc 8a is to be horizontally mounted, to connect parallelogram Steering mechanism, and the axis of the gear of steering wheel 8 with plumb line be it is angled, usually 18 degree, therefore easy to operation；Will be by reality Condition adjusts gap, and stuffing lubricates.

The described two trailing wheel 6b of connection having included by the riding mower of noise reduction measure and hydraulic stepless speed change band Hydraulic stepless speed change drives back axle 24, and as shown in figure 20, this is to remove multiple connecting screw and half back axles, and surplus half Back axle and two plunger pumps and hydraulic control valve group and the schematic elevation view of multiple gears for exposing inside, described back axle are included and are located at Two semiaxis between two rear wheels, are provided with differential mechanism between two semiaxis, and thus differential mechanism is sequentially connected second upwards Plunger pump 24c and hydraulic control valve group stepless speed changing mechanism and brake apparatus, then through hydraulic control valve group connect the first plunger pump 24b from Mechanism, then the belt 22 via the belt pulley in the rotary shaft of the first plunger pump are closed, transmits the power of engine spindle 11, it is special Sign is：The differential mechanism includes a pair of axle shaft gears, the planet wheel assembly between axle shaft gear, the star-wheel 24h of planet wheel assembly Most handy 2 star-wheels, and each tooth number of star is 12；Planet wheel assembly is erected on a larger gear wheel 24g, preferably its The number of teeth is 53；Described gear wheel 24g engages with intermediate speed pinion 24f, and its best number of teeth is 11；Described intermediate speed pinion 24f is coaxial with idler gear 24e and connects firmly, and its best number of teeth is 48；Described idler gear 24e and the speed change of the second plunger pump Gear 24d is engaged, and its best number of teeth is 13, so foring decelerator and reinforcement, and forms differential mechanism and makes turning flexible. The plunger of the second described plunger pump is most handy 5, and the plunger than the first plunger pump is more, the cylinder diameter of each plunger with regard to larger, Pretend as oil motor, output torque is with regard to larger.Because the coaxial of the change-speed gearing of the second plunger pump is provided with brake apparatus Brake disc, be provided with friction plate, brake bar and spring and form brake apparatus on the back axle 24 near brake disc, therefore just It is connected in the foot brake device 12 in the middle part of vehicle frame and Hand brake apparatus 13；The foot brake device 12 and Hand brake apparatus 13 of this car be actually Same set of mechanism.In hydraulic control valve group between the second plunger pump and the first plunger pump, provided with Shift lever, on the one hand regulate and control hydraulic control Oil inlet and outlet in valve group, the angle on the other hand changing the plunger head inclined-plane of the first plunger pump change output speed, therefore It is easy to be connected with the drive shift 14 in the middle part of vehicle frame and reverse drive gear 14b, to form stepless speed changing mechanism；When neutral gear, the first plunger The angle on the plunger head inclined-plane of pump is zero, dallies and serves the effect of clutch without output, the first plunger pump；Drive shift 14 It is connected with reverse drive gear 14b, manipulates stepless speed changing mechanism；When stepping on drive shift 14, the second plunger pump and the first plunger pump it Between hydraulic control valve group on Shift lever, regulate and control hydraulic control valve group on oil inlet；Step on deep, make the big then speed of oil inlet fast；Step on Shallow, the small then speed of oil inlet is slow, therefore realizes stepless shift；When depressing reverse drive gear 14b, in the second plunger pump and the first plunger pump Between hydraulic control valve group on Shift lever it is reverse, make the oil inlet and outlet in regulation and control hydraulic control valve group reverse, make the second plunger pump anti- Turn, drive decelerator below and differential mechanism reversion, be allowed to move backward.Because the second plunger pump is actually when oil motor is used herein , it drives change-speed gearing 24d to be engaged with series of gears, so as to drive two semiaxis and trailing wheel 6b.In the second plunger pump and In hydraulic control valve group between first plunger pump, parking bar is additionally provided with, regulates and controls the interior hydraulic fluid port of hydraulic control valve group, when pulling parking position, Hydraulic fluid port in the D-shaped bar obstruction of the inside of parking bar.Inlet valve 24k is provided with inside back axle 24 to connect outer oil in described driving Box, therefore convenient lubrication；Permanent magnet 24j is additionally provided with back axle 24 in described driving, or with horseshoe magnet, because of You Ci rotation Stream and effect is good, or be located at many places, therefore beneficial to the iron filings for holding each steel and iron parts after wearing for a long time and being mixed into oil.

Again because there is the band dual fail-safe above noise reduction measure and four-wheel included by the riding mower of hydraulic stepless speed change The vehicle frame of thick stick, as shown in Fig. 2 bumper is provided with the front of car, it is characterized in that：Described bumper is parallel bars, or three, or More, and per thick stick it is that two is curved, middle straight pipe or square tube, and also support supports at least two；Parallel bars should be more than list Insurance；As an improvement, described support is not rigidity, but elasticity, such as with spring, or elastomeric material such as rubber or poly- Ammoniacum, therefore be more conducive to buffer.

Again because there is the noise reduction that has below noise reduction measure and vehicle frame included by the riding mower of hydraulic stepless speed change Mowing-apparatus, including height adjusting part point and mowing part；Referring to Fig. 5, height adjusting part point, by parallelogram principle, by The preceding dead axle (18a) and rear dead axle 18c being located on vehicle frame, and be located at and cut preceding moving axis 18b on disk 18 and rear moving axis 18d and therewith The rod member mutually interlocked, and the steel wire rope 18h for pulling, sector gear 18g, ratchet 18f with heighten handle 15 and formed, its It is characterized in：The described preceding dead axle 18a being located on vehicle frame and rear dead axle 18c, and it is located at preceding moving axis 18b and the rear moving axis cut on disk 18d is four summits of parallelogram, and its corresponding side is parallel and equal two-by-two, so, in any case by heightening Handle 15 pulls steel wire rope 18h, and by sector gear 18g, and ratchet 18f heightens gear to several, preceding fixed on vehicle frame Axle 18a and rear dead axle 18c line, always it is parallel with cutting preceding moving axis 18b on disk and rear moving axis 18d, so as to basic On ensure that the upper and lower translation for cutting disk and normal work；But steel wire rope 18h length is still mixed up when practical, and sector Take turns 18g and ratchet 18f allotment.Though it is whole cut disk and be almost be in each gear it is parallel, but it is front and rear have movement, be with dynamic The engine spindle 11 that power belt 21 is ined succession is the center of circle, and being moved apart from longitudinal projection for radius for the first tool rest is passed to through belt 21 Dynamic, and belt 21 also has difference in height, is oblique, can also fortunately use.As can be seen from Figure 6, because heightening the described fan of gear Shape gear 18g has multiple tooth, and now preferably 10 teeth, have 10 grades, such as can cut height in 10-100mm to adjust；Or by conventional 25-85mm, Several shelves are divided preferably to press customer requirement.Referring to Figure 10, the power for part of mowing passes to first from engine spindle 11 through belt 21 Tool rest, then synchronized band 23 pass to the second tool rest, therefore are easy to drive hay knife 20 to work；As an improvement, referring to Figure 14 and Figure 16, Described hay knife 20 is provided with two or more wind wings, and grass is twined in order to cut off, and multiple cutting edges are provided with described wind wing 20a, the angle on the two sides of described cutting edge are not the acute angles at right angle, preferably less than 60 degree；It is further used as improving, it is described Hay knife 20 is provided with multiple hexagonal holes, or further improves, and described hay knife 20 is provided with multiple such as honeycomb or such as point 7b convex-concave is split, therefore beneficial to the audio frequency i.e. noise reduction for changing the high speed Tiny pore for flowing through knife.

The graphical designs of the mowing part of the described mowing-apparatus for having noise reduction and preferred method of thinking, it is the one of the present invention Item significant contribution.As it was previously stated, the scheme of one in front and one in back two knives of original sitting type hay mover, is two-sided V-belt, Three tensioning wheels have also been used, before and after having because of knife, has made to cut the front and rear increasing of disk, causes complete machine to lengthen.Another original sitting type is cut Two knives of careless machine, though it is more expensive double-sided synchronous belt because two knives reversely turn one in front and one in back not to be, it is also handy Two synchronous tension wheels, this causes added cost.It can find with two knives, not be one in front and one in back, not make to cut that disk is front and rear to be increased, And do not turn reversely, without more expensive double-sided synchronous belt, grass does not leak, the approach that knife does not touch, with what methodAnswer is yes.With Illustrate optimum seeking method：Two point widths for taking strip-shaped cutter 20 are diameter D, the gyroaxis by two knives be belt wheel center (23a, 23b) away from for A, 2 circles are drawn, referring to Figure 25, the intersecting front part of two circles is represented with filling hachure, and width B is exactly careless leak-free weight swath B；Make to justify using A as diameter again, angle of circumference perseverance is right angle, is mutually hung down because having set two knives, and is synchronous axial system, therefore two knives are circumference Two sides at angle, it can separately draw multiple angles of circumference and come preferably.There is formula：B=D-A.Referring again to Figure 26, A is changed, first by optimum seeking method 0.618 method takes band wheelspan A=0.618D, mapping, then is gradually increased A, is up to close to D；It is when knife touches soon shown in figure Maximum weight swath B and minimum A.A influences to cut the size of disk 18.Again by formula：

Take designed ratios N=A/D, in general, be preferred in 74%-92%.

Such as 74% is taken, the long D=530 of knife, cutter heart is away from A=390；Swath F=D+A=530+390=920, it is somewhat few, Wish a little bigger good；Heavy swath B=D-A=140, it is enough.

As another embodiment, designed ratios N=A/D=92% is taken, the long D=530 of knife, cutter heart is away from A=490；Then mow The swath F=D+A=530+490=1020 of machine, it is a little bigger, it is good；Weight swath B=D-A=40, also can use.

If take weight swath B=D-A≤20, it is likely that leakage grass, because grass is left and right rolling, and be to be cut disk by askew allow and overwhelmed , just have once in a while sometimes cut less than grass.When practical, the gap of disk inner circumferential and point of a knife is cut preferably in more than 3mm.

Because using PROE-WILDFIRE softwares, therefore easily variable can draw, other softwares can be also used certainly.

Again because there is band forward above noise reduction measure and vehicle frame included by the riding mower of hydraulic stepless speed change to disappear The engine of sound track and the vehicle cover for having noise reduction, as shown in Fig. 4 and Figure 10, engine is drawn to see clearly to exempt to block to have saved；Eliminate the noise The enlarged drawing of groove is as
