Description

The two step wheels of gasoline are from walking snowplow

Technical field

The present invention relates to a kind of for before office building, the light-duty self-propelling snow sweeper of the place cleaning accumulated snow such as garden, sidewalk, be to have on the snowplow of antiskid chain and ice-spur snow brush screw feeder and heat transfer vapour groove and front exhaust pipe and the basis of the snowplow that has safe manoeuvring and front jockey pulley and noise reduction body that monodentate dish becomes many speed, the two step wheels of gasoline of development are from walking snowplow.

Background technology

Though be that timely snow meets 1000000 years, on road, accumulated snow affects traffic.On main road, adopt large-sized power snowplow, its bulky and with high costs, if with tactics of human sea take a lot of work and efficiency low, therefore, various small-sized snowplows arise at the historic moment, and become the indispensability machinery clearing the snow in the winter of many occasions such as office, unit, school, parking lot, square, property plots, garden, nonmotorized vehicle lane institute wide selection.But it is out of this world that any product does not all have, always there are many weak points must be further improved.Snowplow adopts Horizontal type wind-cooling put-put more, and its muffler shell temperature rise is too high, and hot 160 degree that reach, affect safety, and not up to standard, is badly in need of improving, but is difficult to overcome.Sound absorber as the internal combustion engine silencing equipment of put-put particularly, is arranged on exhaust doorway on cylinder cover by extensively, reduces the noise of engine operation process.There is relevant regulation countries in the world to the limiting value of the noise of the garden machines such as various traveling vehicles and hay mover and rotary cultivator and snowplow and agriculture and animal husbandry machinery, and exhaust silencer is exactly such device of giving birth to for reducing exhaust noise.The performance evaluation of sound absorber mainly contains acoustical behavior, the indexs such as aerodynamic quality and structural performance.The considerable part of internal combustion engine belongs to pulsating nature Low Frequency Noise Generator, adopts resistance or impedance again and property and micro-perforated plate muffler more.Mostly the sound absorber of common internal combustion engine is three-chamber sound absorber in particular for the sound absorber of put-put, and noise elimination effect is limited; And outside must have larger containment envelope, as shown in the outer cover (19b) of the snowplow schematic perspective view of Fig. 7, but itself not noise elimination effect, its shell temperature rise superelevation, common different types of machines, snowplow still not, and also have hay mover, though its sound absorber is added with outer cover, very not very useful, or hot, affect safety, can not thoroughly deal with problems.Use snowplow often to run into many situations of not thinking generation: while sometimes sweeping away snow, particularly when ice and snow mingles, or when road conditions are poor, the various defect of original snowplow just do not know how to have occurred more or less, such as: it is not enough that the screw feeder without ice-spur snow brush in the place ahead of sweeping away snow and snow shoveling plate enter snow sometimes; Snow throwing dish is thrown and to be got rid of effect not significantly and get rid of not far; The veer of snow output spot is used not freely sometimes; The little spade of anodontia ice and snow runs into all bad making of some thin ice; The side front steering device in side the place ahead turns sharp turn difficult carrying out while turning at snowplow; Large road wheel without antiskid chain skids along ground, snow pushing forward carefully; Even hold holding of stay cord handle raw pain is also not all right; Also have as the fence of the type of Fig. 7 from motor excessively away from, people reaches regulation and control; And its operating grip does not have the safety measure of maloperation protection; How to solve and how to guard against the sporadic deficiency of many snowplows and shortcoming, be the hard nut to crack in this field always.In order to overcome the deficiency of duty due to each mechanism of snowplow of prior art, simultaneously also in order to invent several dissimilar deicing snow sweepers, the inventor has done multiple design and improvement; Just like silkworm in spring to dead silk not to the utmost, the perfection that the mankind pursue invention is forever continuous, the inventor of association did the experience of hundred domestic and international patents abroad in Switzerland etc. in decades as SENIOR ENGI and the domestic chief engineer of work senior engineer, did a kind of way, the original not outer cover of noise elimination effect to be changed into two chambeies of noise elimination effect, calculate three-chamber sound absorber and just become five chamber sound absorbers, its noise elimination effect has greatly improvement, cost is also similar with former outer cover, temperature drops to 120 degree left and right, former being used on hay mover, the existing adaptive snowplow in installation position that slightly changes, still available; If repay, can make temperature lower than 100 degree, that is just better and safe; Arise at the historic moment, as a result, there are heat transfer vapour groove and front exhaust pipe, a kind of better and safe way is exactly one of safety measure of the present invention vapour channel process, with the groove that is added with water, cover on sound absorber so that cooling, and the hot vapour that the water that adds becomes is directed to the place ahead of sweeping away snow by steam pipe (16), in order to the auxiliary deicing of being heated, this kills two birds with one stone; Simultaneously, also the hot waste gas of sound absorber, by flue gas leading or there is the flue gas leading (17) of noise elimination effect, be also directed to the place ahead of sweeping away snow, both improved soundproof effect, be beneficial to again auxiliary deicing, and making originally from operator close to is too waste gas outlet from the toxic emission of one meter of nose less than at a distance and healthy, has also overcome small gasoline engine waste gas outlet close to air filter import too, 0.3 meter of less than, and easily causing the drawback that part secondary exhaust gas is sneaked into air filter air inlet, this also can say what one action four obtained; Snow becomes ice, and directly difficulty is removed, but when this snow ice, prominent heat vapour and hot waste gas, and local heating, is easily impacted cracking, thus be beneficial to auxiliary deicing, and needn't whole ice heating and melting, also need not heat in addition power consumption; The too much heat in sound absorber place and waste gas are forwarded to needs the place ahead of local heating to go, and this is really not easy to find out, a kind of invention cleverly at last, and on technique and cost, be easily to implement, checked a large amount of patent families both at home and abroad, this innovates really; Further how invention monodentate dish becomes speed again, fundamentally cures the disadvantage that the grinding disk of common snowplow skids; On a kind of basis of the snowplow that has antiskid chain and ice-spur snow brush screw feeder and heat transfer vapour groove and front exhaust pipe by the improved novelty of common snowplow, further improve the snowplow that has safe manoeuvring and front jockey pulley and noise reduction body that becomes many speed for monodentate dish, improvement cooling, noise reduction, energy-conservation, reduction of discharging.Sometimes sweep away snow and need to add lamp, the past does not have.Operating grip is bad holds and grasps discomfort and will improve.And the shelves that hang up are easy to take off and will prevent losing rank once in a while.

The specific embodiment

With reference to suggestion of the present invention and way, can on original snowplow, reequip; The original not outer cover of noise elimination effect is changed into two chambeies of noise elimination effect, calculating three-chamber sound absorber just becomes five chamber sound absorbers, and its noise elimination effect has greatly improvement, cost is also similar with former outer cover, the former five chamber sound absorbers that are used on hay mover, slightly changes installation position, adaptive snowplow, or available.

Also can, with reference to suggestion of the present invention and way, on original snowplow, reequip; The original not outer cover of noise elimination effect is removed, still use three chamber sound absorbers, or with five chamber sound absorbers, see the requirement that different clients is different, at sound absorber peripheral hardware heat transfer vapour groove and front exhaust pipe, preferably adopt the front exhaust pipe that has noise elimination, so that noise elimination effect has greatly improvement.

Preferably adopt suggestion of the present invention and way, on the snowplow of batch production, carry out detailed rules for the implementation.

Because there is no out of this world thing, any product all always has many weak points further to improve, and as invention, is endless.Because the present invention proceeds in two phases, first a kind of common snowplow is improved to the novel snowplow that antiskid chain and ice-spur snow brushes screw feeder and heat transfer vapour groove and front exhaust pipe of having, therefore first talk about the former; State again on front basis, further improve the details that becomes the snowplow that has safe manoeuvring and front jockey pulley and noise reduction body of many speed for monodentate dish.

Because have the snowplow of antiskid chain and ice-spur snow brush screw feeder and heat transfer vapour groove and front exhaust pipe, include, body, motor, the screw feeder 13 for sweeping away snow, body top is provided with a snow output tube, and the top of described snow output tube is provided with and turns to mouth, and the described base edge that turns to mouth is provided with tooth sector 21, the motor that has a horizontal output shaft of longitudinal installation is established at body middle part, After-Body is provided with wheel and push rod 10, described screw feeder is laterally arranged on the front portion of body rotationally, the front lower place of body is provided with ice shoveling plate 15, on the output shaft of described motor, main pulley is installed, described main pulley rotates front belt pulley by belt, described front belt pulley joins with the front propeller shaft of longitudinally installing, the middle part of described front propeller shaft is connected with snow throwing dish 18, simultaneously, the leading section of described front propeller shaft is fixedly connected with the worm screw of worm type of reduction gearing 33, worm-drive engagement in the worm screw of described worm type of reduction gearing 33 and its worm type of reduction gearing, described worm gear is fixedly mounted on the screw conveyor shaft of described screw feeder, described belt coordinates with regulating wheel, described regulating wheel is arranged on front tensioning plate, described front tensioning plate is arranged on body by fulcrum, described fulcrum is positioned at the middle part of front tensioning plate, described regulating wheel, screw feeder is controlled one end that bracing wire is positioned at front tensioning plate, returning spring is positioned at the other end of front tensioning plate, described screw feeder is controlled bracing wire and is connected with the operating handle that is located at the screw feeder of described push rod 10, to coordinate, sweep away snow, on body, set up manual spade, to coordinate, swept ice and snow, therefore still can carry out the general work of sweeping away snow.But it is out of this world that any product does not all have, always there are many weak points must be further improved.General snowplow adopts Horizontal type wind-cooling put-put more, and its muffler shell temperature rise is too high, hot 160 degree that reach, affect safety, and not up to standard, be badly in need of improving, but be difficult to overcome, have to add the outer cover without many railing hurdle net samples of noise elimination effect by stupid way.Sound absorber as the internal combustion engine silencing equipment of put-put particularly, is arranged on exhaust doorway on cylinder cover by extensively, reduces the noise of engine operation process.There is relevant regulation countries in the world to the limiting value of the noise of the garden machines such as various traveling vehicles and hay mover and rotary cultivator and snowplow and agriculture and animal husbandry machinery, and exhaust silencer is exactly such device of giving birth to for reducing exhaust noise.The performance evaluation of sound absorber mainly contains acoustical behavior, the indexs such as aerodynamic quality and structural performance.The considerable part of internal combustion engine belongs to pulsating nature Low Frequency Noise Generator, adopts resistance or impedance again and property and micro-perforated plate muffler more.Mostly the sound absorber of common internal combustion engine is three-chamber sound absorber in particular for the sound absorber of put-put, and noise elimination effect is limited; And outside must have larger containment envelope, as shown in the outer cover 19b of the snowplow schematic perspective view of Fig. 7, but itself not noise elimination effect, its shell temperature rise superelevation, common different types of machines, not snowplow still, and also has hay mover, though its sound absorber is added with outer cover, it is good to see, is deaf person's ear one ornaments in fact, very not very useful, or hot, affect safety, can not thoroughly deal with problems.While sweeping away snow, can run into many situations: while sometimes sweeping away snow, particularly when ice and snow mingles, or when road conditions are poor, the various defect of original snowplow just do not know how to have occurred more or less, such as: it is not enough that the screw feeder without ice-spur snow brush in the place ahead of sweeping away snow and snow shoveling plate enter snow sometimes; Snow throwing dish is thrown and to be got rid of effect not significantly and get rid of not far; The veer of snow output spot is used not freely sometimes; The little spade of anodontia ice and snow runs into all bad making of some thin ice; Side the place ahead is because of but the side front steering device of front jockey pulley 14a or front crawler belt 14, at snowplow, turns sharp turn difficult carrying out while turning to; Large road wheel without antiskid chain skids along ground, snow pushing forward carefully; Even hold holding of stay cord handle raw pain is also not all right; Also have as the fence 24 of the snowplow type of Fig. 7 from motor excessively away from, people reaches the regulation and control of motor; And its operating grip does not have the safety measure of maloperation protection; How to solve and how to guard against the sporadic deficiency of many snowplows and shortcoming, or the existing specious technical phenomena of implied or is exactly the hard nut to crack in each field.In order to overcome the deficiency of duty due to each mechanism of snowplow of prior art, simultaneously also in order to invent several novel deicing snow sweepers, cast a brick to attract jade, just like silkworm in spring to dead silk not to the utmost, the perfection of pursuing invention never rests only uncommon descendant.Because have heat transfer vapour groove and front exhaust pipe, be beneficial to transferring heat; And the ice shoveling plate 15 being provided with in the front lower place of body has tooth, therefore be convenient to shovel ice and snow; On the side of described ice shoveling plate 15, be provided be vented to body front lower place for changing the front exhaust pipe 17 of ice, and be provided with logical vapour to the front lower place of body for changing the hot steam pipe 16 of ice, frangible therefore be beneficial to Shi Bing local heating; Periphery at the sound absorber 12 of motor, is provided with heat transfer vapour groove 19, and described heat transfer vapour groove is the container that adds water, specific heat of water is large, therefore be beneficial to cooling, and described heat transfer vapour groove is provided with hot steam pipe 16, its logical hot vapour to the front lower place of described body for changing the hot steam pipe of ice; And the exhaust outlet that goes out at the sound absorber 12 of described motor is connected to front exhaust pipe 17, its logical waste gas to the front lower place of described body for changing the front exhaust pipe of ice, therefore be beneficial to, conduct heat and auxiliary deicing.

When implementing, it is to be noted especially, because described heat transfer vapour groove is the container that adds water, it has two large features, feature employing it time because of it be to affect counterweight, and quite have an impact to the walking of complete machine is anti-skidding; Because further having done improvement, the described snowplow that has antiskid chain and ice-spur snow brush screw feeder and heat transfer vapour groove and front exhaust pipe, is characterized in that the wheel that described After-Body is provided with is provided with antiskid chain 22.Except grabbing of antiskid chain itself taken off adhesive ability, counterweight is also taken off adhesive ability and is had significant impact anti-skidding grabbing; Because described heat transfer vapour groove adds water, its weight be change with adjustable, so will calculate the volume of a container that affects counterweight, when adding grabbing of the great antiskid chain of water polygamy itself, to take off adhesive ability large, this is self-evident, and quite has an impact to the walking of complete machine is anti-skidding.The second largest feature of the described heat transfer vapour groove that adds water, its walking that affects complete machine, as turned round and climb and fall, will note its height of C.G. especially, and adjust longitudinal potentiality coefficient of stability, undergraduate course professor said, therefore do not repeat.In other words, heat transfer vapour groove is suitable, and container is slightly a little bigger, more how much is adjusted to adding water.
