Description

A kind of snowplough having engine and motor drive

Technical field

The present invention relates to it is a kind of for before office building, garden, the places such as pavement clean the light-duty of accumulated snow and self-propelled sweep away snow Machine is regulated and controled in the snowplough for having antiskid chain and ice-spur snow brush screw feeder and heat transfer vapour slot and front exhaust pipe and using drawstring Fluted disc becomes on the basis of the snowplough for having safe manoeuvring and preceding jockey pulley and noise reduction body of multi-speed, continuously improves and further innovates A kind of tool engine and motor drive snowplough.

Background technique

Though being that timely snow is met 1000000 years, road accumulated snow influences traffic.Large-sized power snowplough is used on main road, Bulky and with high costs, takes a lot of work and low efficiency if with tactics of human sea, 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 The indispensability that clears the snow of winter it is mechanical.But any product is not all perfect in every way, always must further change there are many shortcoming Into.Snowplough mostly uses Horizontal type wind-cooling put-put, and muffler shell temperature rise is excessively high, hot up to 160 degree, influences Safety, and it is not up to standard, it needs to improve, but is difficult to overcome.Silencer is widely used as internal combustion engine especially small gasoline and is started The silencing equipment of machine, is mounted on cylinder cover and is vented doorway, to reduce the noise of engine operation process.Countries in the world are to various Traveling vehicle has related to the graden machines such as grass trimmer and rotary cultivator and snowplough to the limiting value of the noise of agriculture and animal husbandry machinery Regulation, exhaust silencer is exactly such a device to reduce 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 be multiple 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 biggish containment envelope, such as the snowplough of Fig. 7 Shown in the outer cover (19b) of stereoscopic schematic diagram, but itself is acted on without noise elimination, shell temperature rise superelevation, common different types of machines, Not still snowplough, and there are also grass trimmer, though silencer is added with outer cover, and it is not too much very useful or hot, safety is influenced, It cannot thoroughly solve the problems, such as.Using snowplough frequently encounter many be not desired to there is a situation where: when sweeping away snow sometimes, especially 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 is sometimes insufficient into snow；It is not significant and get rid of not far that effect is got rid of in the throwing of snow throwing disk； The direction that turns of snow output spot uses not freely sometimes；The small spade of anodontia ice and snow encounters that some thin ice are all bad to be made；Before side in front of side Diverter, which turns difficulty when sharp turn turns in snowplough, to be carried out；The big traveling wheel of no antiskid chain skids along ground, cannot be carefully to being pushed forward Snow；Even if hold drawstring handle hold raw pain it is not all right；Also as Fig. 7 type fence too far from engine, people Reach regulation；And the safety measure that its operation handle there is not maloperation to protect；How to solve and how to guard against many snowploughs even The deficiency and disadvantage that you occur, are always the hard nut to crack in the field.In order to overcome the prior art snowplough each mechanism The deficiency of caused working condition, 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 the original outer cover without noise elimination effect being changed to noise elimination effect, and calculating three-chamber silencer just becomes five Chamber silencer, 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 changes installation position adaptation snowplough, be also available；If repaying can make temperature lower than 100 degree, that is just more preferably and safe ?；It comes into being, as a result, has heat transfer vapour slot and front exhaust pipe, a kind of is exactly more preferably of the invention with safe method One of safety measure vapour channel process, is covered on the slot added with water to cool down on silencer, and the hot vapour that the water added becomes is led to It crosses steam pipe (16) and is directed to front of sweeping away snow, with the heated auxiliary deicing of benefit, 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 conducive to auxiliary deicing again, and is discharged into exhaust gas of the i.e. waste gas outlet originally too close from operator from nose less than one meter far Place and it is healthy, it is too close 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 becomes ice, and direct difficulty is removed, but works as this snow ice, dashes forward and meets Hot vapour and hot waste gas, local heating are easily cracked by impact, therefore are conducive to auxiliary deicing, without whole ice heating and melting, without In addition heating energy consumption；Heat and exhaust gas excessive at silencer is set to go to and need 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 be to be easy to implement in technique and cost, check a large amount of domestic and international patent families, this It really innovates, perhaps it can be said that having started a kind of with antiskid chain and existing heat transfer vapour slot, and has 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 base of the common improved novel snowplough for having antiskid chain and ice-spur snow brush screw feeder and conduct heat vapour slot and front exhaust pipe of snowplough On plinth, the snowplough for having safe manoeuvring and preceding jockey pulley and noise reduction body for becoming multi-speed for monodentate disk is further improved, has started one Kind of monodentate disk becomes multi-speed and cooling, noise reduction, energy conservation, emission reduction walking machine new technical field.Though sweeping away snow is to seem capable , still, new problem occurs again；What the purpose swept away snow? it is to scan out a road convenient for people's walking；But problem Though be the thick snow of road being to be swept, however because snow is swept unclean, a thin layer can be left on the road, due to trampling or The sun, which shines, the reasons such as melted and froze, this thin layer left on the road is very sliding just at ice and snow mixed layer, not only influences walking Safety, and very hard and smooth slip and be difficult to clean off；How ice and snow mixed layer is swept away snow and removed with mechanization, be that machinery sweeps away snow The long-term insoluble hard nut to crack of machine institute.If using blowing snow device and if inhaling snow device or vibrator etc., dynamic power machine is driven just It is remote and inconvenient, market prediction and a kind of tool engine is actually needed and the snowplough of motor drive emerges, gradually to change Into with constantly bring forth new ideas.

Specific embodiment

With reference to suggestion and method of the invention, can be reequiped on original snowplough；There is no noise elimination to act on original Outer cover is changed to two chambers of noise elimination effect, and calculating three-chamber silencer just becomes five chamber silencers, and noise elimination effect is much improved, at 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 ?.

It reference may also be made to suggestion and method of the invention, 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 slot and front exhaust pipe, preferably with the front exhaust pipe for having noise elimination, so that noise elimination effect is much improved.

Preferably with suggestion and method of the invention, carry out detailed rules for the implementation on the snowplough of batch production.

Because of thing inperfect in every way, any product all must be always further improved there are many shortcoming, as hair Bright is endless.Because the present invention proceeds in two phases, first a kind of common snowplough is improved to novel have antiskid chain And ice-spur avenges the snowplough of brush screw feeder and conduct heat vapour slot and front exhaust pipe, therefore first say the former；It is stated on the basis of preceding again, into one Step improves the details for becoming the snowplough for having safe manoeuvring and preceding jockey pulley and noise reduction body of multi-speed for monodentate disk.

Because there is the snowplough of antiskid chain and ice-spur snow brush screw feeder and conduct heat vapour slot 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 Steering mouth base edge 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 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 and tensioning wheel cooperate, and before the tensioning wheel is mounted on tensioning plate, the preceding tensioning plate passes through fulcrum It is mounted 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, and the screw feeder controls bracing wire and is located at the screw feeder of the push rod 10 Operating handle is connected, and sweeps away snow to cooperate；It is attached to manual spade on body, sweeps ice and snow to cooperate；Therefore it still carries out general Work of sweeping away snow.But any product is not all perfect in every way, and always there are many shortcomings must be further improved.Generally sweep Snow machine mostly uses Horizontal type wind-cooling put-put, and muffler shell temperature rise is excessively high, hot to influence safety up to 160 degree, and It is not up to standard, it needs to improve, but be difficult to overcome, the outer of many railing column net samples of no noise elimination effect have to be added with stupid method Cover.Silencer is widely used as the silencing equipment of internal combustion engine especially put-put, is mounted on 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 relevant regulation, and it is to subtract that exhaust silencer, which is exactly such a, 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 mostly uses resistance or impedance multiple and property and micro-perforated plate muffler. The silencer of common internal combustion engine is mostly three-chamber silencer, noise elimination effect in particular for the silencer of put-put It is limited；And outside must have biggish containment envelope, as shown in the outer cover 19b of the snowplough stereoscopic schematic diagram of Fig. 7, but itself It does not eliminate the noise effect, shell temperature rise superelevation, common different types of machines, not still snowplough, and also there are also grass trimmer, silencers It is ear-ornaments of deaf person in fact though being looked at added with outer cover, it is not too much very useful or hot, safety is influenced, it cannot be thorough It solves the problems, such as.Many situations can be encountered when sweeping away snow: when sweeping away snow sometimes, especially 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: the stirring without ice-spur snow brush in front of sweeping away snow Dragon and snow shoveling plate are sometimes insufficient into snow；It is not significant and get rid of not far that effect is got rid of in the throwing of snow throwing disk；The direction that turns of snow output spot uses not sometimes Freely；The small spade of anodontia ice and snow encounters that some thin ice are all bad to be made；Because but before the side of preceding jockey pulley 14a or preceding crawler belt 14 in front of side Diverter turns difficulty when sharp turn turns in snowplough and carries out；The big traveling wheel of no antiskid chain skids along ground, cannot be carefully to being pushed forward Snow；Even if hold drawstring handle hold raw pain it is not all right；Also as Fig. 7 snowplough type fence 24 from engine Too far, people reaches the regulation of engine；And the safety measure that its operation handle there is not maloperation to protect；How to solve and how to prevent Showing specious technical phenomena for the sporadic insufficient and disadvantage of many snowploughs or implied or is exactly the long-standing of each field Problem.Working condition caused by each mechanism in order to overcome the shortcomings 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. Because having heat transfer vapour slot and front exhaust pipe, it is conducive to transmitting heat；And the ice shoveling plate 15 being equipped in the front lower place of body be it is with teeth, Therefore convenient for shovel ice and snow；On the side of the ice shoveling plate 15, the front exhaust for being used to change ice equipped with the front lower place for being vented to body Pipe 17, and the hot vapour pipe 16 for being used to change ice of the front lower place equipped with steaming to body, thus it is frangible conducive to Shi Bing local heating； In the periphery of the silencer 12 of engine, it is equipped with heat transfer vapour slot 19, the heat transfer vapour slot is the container for adding water, the specific heat of water Greatly, therefore it is conducive to cooling, and the heat transfer vapour slot is equipped with hot vapour pipe 16, the use of logical hot vapour to the front lower place of the body The hot vapour pipe of Yu Huabing；And it is connected to front exhaust pipe 17 in the exhaust outlet that goes out of the silencer of the engine 12, logical exhaust gas arrives The front exhaust pipe for being used to change ice of the front lower place of the body, therefore it is conducive to deicing of conducting heat and assist.

When implementing, it is to be particularly noted that it has a two major features because the heat transfer vapour slot is the container for adding water, one A feature is when using it because it is to influence counterweight, and quite have an impact to the slip-resistant against foot traffic of complete machine；Because further changing Good, the described snowplough for having antiskid chain and ice-spur snow brush screw feeder and conduct heat vapour slot and front exhaust pipe, it is characterised in that described The wheel that After-Body is equipped with is equipped with antiskid chain 22.In addition to the grabbing and take off adhesive ability of antiskid chain itself, counterweight is also grabbed to anti-skidding Taking off adhesive ability has significant impact；Because the heat transfer vapour slot is to add water, weight is variation and is adjusted, so to count Calculate the volume of a container for influencing counterweight, when adding water polygamy great, it is big that the grabbing of antiskid chain itself takes off adhesive ability, this be do not say and Analogy, and quite have an impact to the slip-resistant against foot traffic of complete machine.The second largest feature of described plus water the heat transfer vapour slot, influences complete machine Walking such as turn and climb and fall, it is important to note that its height of C.G., and longitudinal potentiality coefficient of stability is calculated, undergraduate course professor said, Therefore it does not repeat.In other words, heat transfer vapour slot is suitable, the bigger point of container, then with adding how much water is adjusted to.

Because further improveing, described have antiskid chain and ice-spur snow brush screw feeder and conduct heat vapour slot and front exhaust pipe are swept Snow machine, it is characterised in that the screw feeder 13 of the front for being rotationally transversely mounted on body, spiral screw feeder it is outer Edge is equipped with multiple ice-spur 13a and multiple snow brush 15b, or optionally first, therefore having it to assist deicing and the effect of sweeping away snow.
