Description
Technical field
The present invention relates to a kind of for by garden, park and road, the hay mover that physical culture place cuts the grass on a lawn to be main to improve
Purpose is to add safety circuit protection measures, makes and is conducive to mowing, noise reduction, the hay mover of environmental protection and safety, special
It is not that one kind drives the double careless wide cut hay mover of tilting in the same direction pair of hay knife without tensioning wheel ordinary straps.
Background technology
Hay mower is widely used in the selected mode of hobby by people to mow.Due to the hay mover of hand push
Mobility is poor, and in putting into practice when mowing, due to the anterior narrower swath of hay mover, so repeat to cut and leak the phenomenon cut often having
Occur, benefit must be gone to cut, it is very arduous that operator's walking is mowed.If with sitting type, being also riding mower, then it is seated than station
And feel different, but noise is big.If the prominent position that disseats of people, protects for original 3 seconds;Dan has rushed 9 meters or danger Jiu the meter per seconds of Suan 3.
Silencer is particularly the silencing equipment of put-put by internal combustion engine is widely used as, and is arranged on cylinder cover
Valve port is reducing the noise of engine operation process.Countries in the world are to various traveling vehicles and the pole of the noise of hay mover
Limit value has the regulation of correlation, and exhaust silencer is exactly such a device to reduce exhaust noise and life.The property of silencer
Can evaluate mainly has the indexs such as acoustical behavior, aerodynamic quality and structural behaviour.It is low that the considerable part of internal combustion engine belongs to pulsating nature
Frequency noise source, is answered and property and micro-perforated plate muffler using resistance or impedance more.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 effect of itself not eliminating the noise.Moreover, its shell temperature rise is higher, hot, affects safety.If plus anechoic trap ought have improvement.
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 many gears adjustable, this peace to operating the pin of pedestrian
The security regulations of strict control must be pressed entirely.This typically does prosthetic foot test.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, individually prosthetic foot safety is measured but by people, then all affect to cut
Careless machine order.Improved idea often allows hay knife to be elevated at several millimeters of chassis.But because cutter is the local 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 two 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 guarantee ten thousand none go out
Safety problem.A kind of inventive concept is being hovered such as ghost:If with thick soft foamed plastics by mowing table and hay mover many places
Outsourcing it, it is expected to receive the effect of security protection and noise abatement, be really that my observations may contain a grain of truth.It is many again to work as safer using safety circuit protection measures.
In order to avoid two knives adjacent gap caused by leakage cut phenomenon, two of original sitting type hay mover
Knife, typically one in front and one in back.Figure 23 is refer to, this is that the transmission of one in front and one in back two knives of original sitting type hay mover is illustrated
Figure, 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 is 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, makes to cut and increase before and after disk, cause wheel base to increase, and whole machine is lengthened, car revolution half
Footpath becomes big, and longitudinal potentiality coefficient of stability is deteriorated, and cost is added, and these are all undesirable.Another kind of original sitting type
Two knives of hay mover, though not being tandem, referring to Figure 24, because two knives are reversely to turn, so as to non-interference, be
Double-sided synchronous belt, also handy two synchronous tension wheels, this causes added cost.If driven without tensioning wheel and with ordinary straps,
Being can reduces cost;But without tensioning, belt is not handy with regard to Tai Song, unless primary and secondary belt wheel spacing further significantly shortens;It is double
Unavoidable ground will have and cut rate again and cut with leakproof between hay knife, and multiplex pair of hay knife is smaller than knife diameter;So require double
Hay knife is reversely rotated, and requires that double hay knives are staggeredly provided with certain phase place, 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 are improved, more undesirable be because
Double hay knives are reversely rotated and can not simultaneously be provided with the rear Lysimachia sikokiana and side Lysimachia sikokiana of wide cut, and one kind is objectively needed on market without tensioning
Wheel ordinary straps are driven the double careless wide cut hay mover of tilting in the same direction pair of hay knife and are emerged.
The content of the invention
The present invention relates to a kind of for by garden, park and road, the hay mover that physical culture place cuts the grass on a lawn to be main to improve
Purpose does not still add safety circuit protection measures, makes resultant effect not only improve mowing, and operation is comfortable, and variable speed has again
Beneficial to noise reduction, environmental protection and safety, and it is in order to be able to reduces cost;But without tensioning, belt is not handy with regard to Tai Song, except non-master
Secondary belt wheel spacing further significantly shortens;Unavoidable ground will have and cut rate again and cut with leakproof between double hay knives, multiplex pair of hay knife
It is smaller than knife diameter;So require that double hay knives are reversely rotated, and require that double hay knives are staggeredly provided with certain phase place, this is just
Double mutual invariablenes turning speeds of hay knife are required it is necessary to synchronous cog belt;But problem is that not only tension structure is complicated, synchronous cog belt
And wheel cost is improved, more undesirable is because the reverse rotation of double hay knives can not be while be provided with rear Lysimachia sikokiana and the side row of wide cut
Grass, objectively needs a kind of without the double careless wide cut mowing machine side of the tilting in the same direction pair of hay knife of tensioning wheel ordinary straps drive on market
Generation.
The present invention solve its technical problem adopt the technical scheme that hay mover to there is safety circuit protection measures and
Safeguard protection has the pioneer of the hay mover of noise reduction and updates and perfect drive tilting in the same direction double cut without tensioning wheel ordinary straps

Connection, such as 4 strings 4 are simultaneously respectively combined by 16 pipes, and, the arcuately covering of the fan arrangement of best multitube expands angular field of view with profit;
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 just can be started after driver sits down;If driver is left behind seat, there is the list of 3-5 seconds
Trigger postpones flame-out control, and this sounds and 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 suddenly logical suddenly disconnected, particularly when driver falls accidentally, the unit for having the 3-5 seconds postpones flame-out control, after waiting the 3-5 seconds
It is flame-out;The hay mover speed of travel makes to take most at a slow speed one meter per second at 3.6 to 15 kilometers/hour, both, also to go out 3-5 rice, or ten
Several meters far could stop, it is conceivable that this is to the trick fallen or barrier how it feels;Although practising under normal conditions
Think and often flame-out control is postponed using the unit for there are the 3-5 seconds, but in order to prevent unsafe hidden danger, it is necessary to new design
The reliable and less expensive seat switch of non-conventional design, described seat switch must be safe, when seat is shaken up and down

Again because there is the noise reduction that has below the vehicle frame included by the riding mower of noise reduction measure and 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 front dead axle (18a) and rear dead axle 18c being located on vehicle frame, and it is located at the front moving axis 18b and rear moving axis 18d cut on disk 18 and therewith
The rod member for mutually interlocking, and for the steel wire rope 18h of pulling, sector gear 18g, ratchet 18f and heightens handle 15 and is constituted, its
It is characterized in that:The described front dead axle 18a being located on vehicle frame and rear dead axle 18c, and it is located at front 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
Pulling steel wire rope 18h, and by sector gear 18g, ratchet 18f is front fixed on vehicle frame heightening gear to several for handle 15
The line of axle 18a and rear dead axle 18c, is always parallel with the front moving axis 18b and rear moving axis 18d that cut on disk, so as to basic
On ensure that the upper and lower translation and normal work for cutting disk;But the length of steel wire rope 18h, and sector are still mixed up when practical
The allotment of wheel 18g and ratchet 18f.It is with dynamic though entirely cut disk to be almost in each gear is parallel, but has movement in front and back
The engine spindle 11 that power belt 21 is ined succession is the center of circle, percutaneously passes to moving for radius apart from longitudinal projection for the first tool rest with 21
Dynamic, and belt 21 also has difference in height, is oblique, fortunately can also 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, there is 10 grades, for example, can cut height to adjust in 10-100mm;Or by conventional 25-85mm,
Several shelves are divided preferably to press customer requirement.Referring to Figure 10, from engine spindle 11, percutaneous band 21 passes to first to the power of mowing part
Tool rest, then synchronized band 23 passes to the second tool rest, therefore be easy to drive hay knife 20 to work;As improvement, referring to Figure 14 and Figure 16,
Described hay knife 20 is provided with two or more wind wings, and in order to cut off grass is twined, and on described wind wing multiple cutting edges are provided with
20a, the angle on the two sides of described cutting edge is not right angle, preferably less than 60 degree of acute angle;It is further used as improving, it is described

The graphical designs and preferred method of thinking of the mowing part of the described mowing-apparatus for having a noise reduction, are 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 are also used, before and after having because of knife, has been made to be cut and increase before and after disk, caused whole machine to lengthen.Another kind of original sitting type cuts
Two knives of careless machine, are more expensive double-sided synchronous belts because two knives are reversely to turn though not being tandem, also handy
Two synchronous tension wheels, this causes added cost.Can find with two knives, not be one in front and one in back, not make to cut and increase before and after disk,
And reversely do not turn, without more expensive double-sided synchronous belt, grass does not leak, and what method is the approach that knife is not touched useAnswer is yes.With
Diagram 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, draws 2 circles, and referring to Figure 25, the intersecting front part filling hachure of two circles is represented, width B is exactly careless leak-free weight swath
B;Make again to justify as diameter with A, it is right angle that angle of circumference is permanent, is mutually hung down because setting two knives, and is synchronous axial system, therefore two knives are circumference
Two sides at angle, can separately draw multiple angles of circumference and come preferred.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 close D to the maximum;It is when knife is touched soon shown in figure
Maximum weight swath B and minimum A.A affects the size for cutting disk 18.Again by formula:
Designed ratios N=A/D are taken, in general, is preferred in 74%-92%.
74%, the long D=530 of knife are for example taken, cutter heart is away from A=390;Swath F=D+A=530+390=920, it is somewhat few,
Wish a little bigger good;Weight swath B=D-A=140, it is enough.
As another embodiment, designed ratios N=A/D=92% are taken, the long D=530 of knife, cutter heart is away from A=490;Then mow
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.
Because grass is that left and right is shaken, and cut disk and overwhelmed by askew allowing if taking weight swath B=D-A≤20, it is likely that leakage grass
, just have once in a while sometimes cut less than grass.When practical, the gap for cutting disk inner circumferential with point of a knife is preferably in more than 3mm.
Because using PROE-WILDFIRE softwares, therefore easily variable can draw, other softwares can be also used certainly.
