Has the four-wheel hay mower of the oval vertical potentiality floating shock-absorbing of front wheel suspension

Technical field

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 is to add safety circuit protection measures, makes and is advantageous to mow, noise reduction, the hay mover of environmental protection and safety, particularly one kind Has the four-wheel hay mower of the oval vertical potentiality floating shock-absorbing of front wheel suspension.

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.

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.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 again to use safety circuit protection measures 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 a kind of while had There is the four-wheel hay mower for going out careless outlet after two to emerge, make grass enter to collect straw bag in the hope of not stifled grass.In the market is objectively special A kind of four-wheel hay mower for having the oval vertical potentiality floating shock-absorbing of front wheel suspension is not needed, in the hope of in high-end hay mower Upper shock-absorbing.

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.

The technical scheme adopted by the invention to solve the technical problem is that with have the hay mover of safety circuit protection measures and Safeguard protection have noise reduction hay mover and without tensioning wheel ordinary straps drive the tilting double careless wide cut hay movers of hay knife double in the same direction with And have to go out on the basis of the four-wheel hay mower of careless outlet after two simultaneously, objectively especially need to improve by the market A kind of oval vertical potentiality floating shock-absorbing of tool front wheel suspension four-wheel hay mower, in the hope of being kept away on high-end hay mower Shake.

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),
