Description

Using drawstring come the snowplough that regulates and controls

Technical field

The present invention relates to it is a kind of be used for office building before, garden, the place such as pavement clean the light-duty of accumulated snow and self-propelled sweep away snow Machine, is novel to have antiskid chain and ice-spur snow brush screw feeder and heat transfer vapour groove and front exhaust pipe by common snowplough is improved in one kind Snowplough on the basis of, it is perfect to have safe manoeuvring and preceding jockey pulley and noise reduction machine using drawstring come what the fluted disc that regulates and controls became multi-speed The snowplough of body.

Background technology

Though being that timely snow is met 1000000 years, accumulated snow influences traffic on road.Large-sized power snowplough is used on main road, its Bulky and with high costs, takes a lot of work if with tactics of human sea and efficiency is low, and therefore, various small-sized snowploughs come into being, As in many occasion institute wide selections such as organ, unit, school, parking lot, square, property plots, garden, non-motorized lane Winter clear the snow indispensability machinery.But any product is all no perfect in every way, always has many shortcomings further to change Into.Snowplough uses Horizontal type wind-cooling put-put more, its muffler shell temperature rise is excessive, hot up to 160 degree, influences Safety, and it is not up to standard, it need to improve, but be difficult to overcome.Silencer is widely used as internal combustion engine particularly small gasoline and is started The silencing equipment of machine, is vented doorway on cylinder cover, to reduce the noise of engine operation process.Countries in the world are to various Traveling vehicle has related to the limiting value of the graden machine such as grass trimmer and rotary cultivator and snowplough to the noise of agriculture and animal husbandry machinery Regulation, exhaust silencer is exactly such a to reduce the device of exhaust noise and life.The performance evaluation of silencer mainly has The indexs such as acoustical behavior, aerodynamic quality and structural behaviour.The considerable part category pulsating nature Low Frequency Noise Generator of internal combustion engine, is adopted more With resistance or impedance is answered and property and micro-perforated plate muffler.The silencer of common internal combustion engine is in particular for put-put Silencer be mostly three-chamber silencer, noise elimination effect is limited；And outside must have larger containment envelope, such as the snowplough of Fig. 7 Shown in the outer cover (19b) of schematic perspective view, but itself is acted on without noise elimination, its shell temperature rise superelevation, common different types of machines, Not still snowplough, and also grass trimmer, though its silencer is added with outer cover, and it is not too much very useful or hot, safety is influenced, Cannot thoroughly it solve the problems, such as.Many situations for being not desired to occur are frequently encountered using snowplough：When sweeping away snow sometimes, particularly in ice and snow When mingling, or when road conditions are poor, the various defect of original snowplough just do not know how more or less occur, such as： The screw feeder brushed without ice-spur snow and snow shoveling plate in front of sweeping away snow are sometimes into snow deficiency；Snow throwing disk throws that to get rid of effect not notable and get rid of not far； The direction that turns of snow output spot uses not freely sometimes；The small spade of anodontia ice and snow runs into that some thin ice are all bad to be made；Before side in front of side Steering gear turns difficult when sharp turn turns to carry out in snowplough；The big traveling wheel of no antiskid chain skids along ground, it is impossible to carefully to being pushed forward Snow；Even if hold drawstring handle hold must give birth to pain it is also not all right；Also as Fig. 7 type fence from engine too far, people Reach regulation and control；And its operation handle there is not the safety measure that maloperation is protected；How to solve and how to guard against many snowploughs even The deficiency and shortcoming that you occur, are always the hard nut to crack in the field.In order to overcome each mechanism of the snowplough of the prior art The deficiency of caused working status, and also to invent several different types of deicing snow sweepers, the present inventor has made a variety of set Meter and improvement；Just like silkworm in spring to dead silk not to the utmost, the mankind pursue invention perfection be it is forever continuous, associate the present inventor's decades , as SENIOR ENGI and the domestic experience made senior engineer chief engineer and did hundred domestic and international patents, to do one in the foreign countries such as Switzerland Kind method, is two chambers for not having the outer cover that noise elimination acts on to be changed to noise elimination effect originally, calculating three-chamber silencer just becomes five Chamber silencer, its noise elimination effect are much improved, and cost is also similar with former outer cover, and temperature drops to 120 degree or so, and original, which is used in, mows On machine, now slightly change installation position adaptation snowplough, or it is available；If repaying can make temperature be less than 100 degree, that is just more preferably and safe ；Come into being, as a result, have heat transfer vapour groove and front exhaust pipe, a kind of more preferable and safety method is exactly the present invention One of safety measure vapour channel process, is covered on to cool down on silencer with the groove added with water, and the hot vapour that the water added becomes is led to Cross steam pipe (16) and be directed to front of sweeping away snow, with the heated auxiliary deicing of profit, this kills two birds with one stone；Meanwhile also the heat of silencer Exhaust gas, by flue gas leading or have noise elimination act on flue gas leading (17), also lead to sweep away snow front, both improve noise elimination effect, It is beneficial to auxiliary deicing again, and i.e. waste gas outlet originally too near from operator is discharged into far from exhaust gas of the nose less than one meter Place and it is healthy, it is too near from air filter import to also overcome small gasoline engine waste gas outlet, less than 0.3 meter, and easily causes portion Secondary the drawbacks of being mixed into air filter air inlet, it is four to obtain at one stroke that this, which can also say,；Snow is changed into ice, and direct difficulty is removed, but works as this snow ice, dashes forward and meets Hot vapour and hot waste gas, local heating, is easily cracked by impact, therefore beneficial to auxiliary deicing, without overall ice heating and melting, without In addition heating energy consumption；Heat excessive at silencer is gone to exhaust gas needs to go in front of local heating, this is really not easy to find out, It a kind of at last can cleverly invent, and easily implement in technique and cost, checked a large amount of domestic and international patent families, this Really innovate, perhaps it can be said that having started a kind of with antiskid chain, and existing heat transfer vapour groove, and have sweeping away snow for front exhaust pipe Machine, further invention monodentate disk become multi-speed, fundamentally cure common snowplough grinding disk skid disadvantage, one kind by The common improved novel base for having antiskid chain and the snowplough of ice-spur snow brush screw feeder and conduct heat vapour groove and front exhaust pipe of snowplough On plinth, further improve has safe manoeuvring and the snowplough of preceding jockey pulley and noise reduction body for monodentate disk change multi-speed, has started one That kind of monodentate disk becomes multi-speed and cooling, noise reduction, the new technical field of energy saving, emission reduction walking machine.

Embodiment

Suggestion and method with reference to the present invention, can reequip on original snowplough；There is no what noise elimination acted on original Outer cover is changed to two chambers of noise elimination effect, and calculating three-chamber silencer just becomes five chamber silencers, its noise elimination effect is much improved, into This is also similar with former outer cover, five chamber silencers of the original on grass trimmer, slightly changes installation position, is adapted to snowplough, still may be used .

Suggestion and the method for the present invention is reference may also be made to, is reequiped on original snowplough；Originally without noise elimination effect Outer cover remove, still with three chamber silencers, or with five chamber silencers, the different requirement of different clients is seen, in silencer peripheral hardware Conduct heat vapour groove and front exhaust pipe, preferably with the front exhaust pipe for having noise elimination, so that noise elimination effect is much improved.

Suggestion and method preferably with the present invention, carry out detailed rules for the implementation on the snowplough of batch production.

Because without thing perfect in every way, any product all always has many shortcomings further to improve, as hair Bright is endless.Because the present invention proceeds in two phases, a kind of commonly snowplough is first improved to novel have antiskid chain And the snowplough of ice-spur snow brush screw feeder and conduct heat vapour groove and front exhaust pipe, therefore first say the former；State again on the basis of preceding, into one Step improves the details for having safe manoeuvring and the snowplough of preceding jockey pulley and noise reduction body for becoming multi-speed for monodentate disk.

Because having antiskid chain and the snowplough of ice-spur snow brush screw feeder and conduct heat vapour groove and front exhaust pipe, include：Body, hair Motivation, the screw feeder 13 for sweeping away snow；A snow output tube is equipped with above body, the top of the snow output tube, which is equipped with, turns to mouth, described The base edge of steering mouth be equipped with tooth sector 21,；The longitudinally mounted engine for having a horizontal output shaft is set in the middle part of body, After-Body is equipped with wheel and push rod 10, and the screw feeder is rotationally transversely mounted on the front portion of body, the front lower place of body Equipped with ice shoveling plate 15, main pulley is installed on the output shaft of the engine, the main pulley makes preceding belt by belt Wheel rotation, the front pulley connect with longitudinally mounted front propeller shaft, and the middle part of the front propeller shaft is connected with snow throwing disk 18, Meanwhile the front end of the front propeller shaft is fixedly connected with the worm screw of worm type of reduction gearing 33, the worm type of reduction gearing 33 worm screw engages with the worm-drive in its worm type of reduction gearing, and the worm gear is fixedly mounted on the screw feeder of the screw feeder On axis, the belt coordinates with tensioning wheel, and the tensioning wheel is installed on preceding tensioning plate, and the preceding tensioning plate passes through fulcrum On body, the fulcrum is located at the middle part of preceding tensioning plate, and the tensioning wheel, screw feeder control bracing wire are located at preceding tensioning wheel One end, returning spring are located at the other end of preceding tensioning wheel, screw feeder of the screw feeder control bracing wire with being located at the push rod 10 Operating handle is connected, and sweeps away snow to coordinate；Manual spade is attached on body, ice and snow is swept to coordinate；Therefore still carry out general Work of sweeping away snow.But any product is all no perfect in every way, always has many shortcomings further improved.Generally sweep Snow machine uses Horizontal type wind-cooling put-put more, its muffler shell temperature rise is excessive, hot to influence safety up to 160 degree, and It is not up to standard, need to improve, but be difficult to overcome, have to be added with stupid method no noise elimination effect many bar railing column net samples it is outer Cover.Silencer is widely used as the silencing equipment of internal combustion engine particularly put-put, the exhaust valve on cylinder cover Mouthful, to reduce the noise of engine operation process.Countries in the world are to various traveling vehicles and grass trimmer and rotary cultivator and sweep away snow The limiting value of the noise of the graden machines such as machine and agriculture and animal husbandry machinery has a relevant regulation, and exhaust silencer is exactly such a to subtract Small exhaust noise and the device of life.The performance evaluation of silencer mainly has acoustical behavior, aerodynamic quality and structural behaviour etc. Index.The considerable part category pulsating nature Low Frequency Noise Generator of internal combustion engine, more using resistance or impedance is answered and property and micro-perforated plate muffler. The silencer of common internal combustion engine is three-chamber silencer mostly in particular for the silencer of put-put, and noise elimination acts on It is limited；And outside must have larger containment envelope, as shown in the outer cover 19b of the snowplough schematic perspective view of Fig. 7, but itself Do not eliminate the noise effect, its shell temperature rise superelevation, common different types of machines, not still snowplough, and also grass trimmer, its silencer It though added with outer cover, look at, be ear-ornaments of deaf person in fact, it is not too much very useful or hot, influence safety, it is impossible to thoroughly Solve the problems, such as.Many situations can be run into when sweeping away snow：When sweeping away snow sometimes, particularly when ice and snow mingles, or when road conditions are poor, The various defect of original snowplough just do not know how more or less occur, such as：Stirring without ice-spur snow brush in front of sweeping away snow Dragon and snow shoveling plate are sometimes into snow deficiency；Snow throwing disk throws that to get rid of effect not notable and get rid of not far；Snow output spot turns direction sometimes with not Freely；The small spade of anodontia ice and snow runs into that some thin ice are all bad to be made；Because but before the side of preceding jockey pulley 14a or preceding crawler belts 14 in front of side Steering gear, difficult when sharp turn turns to carry out is turned in snowplough；The big traveling wheel of no antiskid chain skids along ground, it is impossible to carefully to being pushed forward Snow；Even if hold drawstring handle hold must give birth to pain it is also not all right；Also as Fig. 7 snowplough type fence 24 from engine Too far, people reaches the regulation and control of engine；And its operation handle there is not the safety measure that maloperation is protected；How to solve and how to prevent The standby sporadic insufficient and shortcoming of many snowploughs, or it is exactly the long-standing of each field that implied or, which shows specious technical phenomena, Problem.In order to overcome the shortcomings of working status caused by each mechanism of the snowplough of the prior art, and also to invent several new The deicing snow sweeper of type, casts a brick to attract jade, only uncommon descendant just like silkworm in spring to dead silk not to the utmost, pursue the perfect of invention and never rest.
