Description

Snow sweeper with rear dragging inclined acute angle sliding cutting snow pusher

Technical Field

The invention relates to a light self-propelled snow sweeper used for sweeping accumulated snow in places such as the front of an office building, a courtyard, a sidewalk and the like, which is continuously improved and further innovated on the basis of a snow sweeper with an anti-skid chain, an ice-tooth snow brush auger, a heat transfer steam tank and a front exhaust pipe and a snow sweeper with a fluted disc which is regulated and controlled by a pull rope and has multiple speeds, a safety control, a front auxiliary wheel and a noise reduction machine body.

Background

Although the snowfall affects the traffic in the morning, the snowfall on the road affects the traffic. The large-scale power snow sweeper is adopted on a large road, the size is large, the cost is high, and labor is consumed and the efficiency is low if people use a sea tactic, so that various light and small snow sweepers are produced and become necessary machines for removing snow in winter widely selected in many occasions such as offices, units, schools, parking lots, squares, property districts, gardens, non-motor vehicle lanes and the like. However, any product is not perfect, and always has many defects to be further improved. The snow sweeper mostly adopts a horizontal air-cooled small gasoline engine, the temperature rise of a silencer shell is overhigh, the temperature is 160 ℃, the safety is affected, the snow sweeper does not reach the standard, and the improvement is urgently needed but is difficult to overcome. Mufflers are widely used as muffling devices for internal combustion engines, particularly small gasoline engines, and are mounted on exhaust ports of cylinder heads to reduce noise during engine operation. In all countries of the world, there are regulations relating to the noise limit of garden machines and farm and pasture machines, such as various walking vehicles, lawn mowers, rotary tillers, snow plows, etc., and the exhaust muffler is one of the devices used to reduce exhaust noise. The performance evaluation of the silencer mainly has the indexes of acoustic performance, aerodynamic performance, structural performance and the like. A considerable part of the internal combustion engine belongs to a pulsating low-frequency noise source, and resistance or impedance renaturation and a micropore plate silencer are mostly adopted. The common silencer of the internal combustion engine, particularly the silencer used for a small gasoline engine, is mostly a three-cavity silencer, and has limited silencing effect; and the exterior needs to have a larger protective outer cover, as shown in the outer cover (19b) of the snowplow three-dimensional schematic diagram of fig. 7, but the outer cover does not have the noise elimination function, the temperature rise of the outer cover is ultrahigh, various machine types are common, the snowplow is not only a snowplow, but also a mower, and the noise eliminator is provided with the outer cover, is not too top-used, is hot, influences the safety, and can not thoroughly solve the problem. Many unwanted situations are often encountered with snow plows: sometimes, when snow is swept, particularly when the snow and ice are mixed, or when the road conditions are poor, various defects of the original snow sweeper are not known to occur more or less, such as: the auger and the snow shoveling plate of the ice-tooth-free snow brush in front of the snowplow sometimes have insufficient snow entering; the throwing effect of the snow throwing disc is not obvious and not far; the rotation direction of the snow outlet is not freely used sometimes; the small ice and snow spade without teeth is not good when meeting a little thin ice; the front side steering gear in the front side is difficult to push when the snowplow turns in a sharp bend; the large walking wheel without the antiskid chain slips along the ground and cannot push snow forward well; even if the hand gripping the pull rope handle is painful, the hand cannot hold the pull rope handle; the rest of the fences of the type shown in FIG. 7 are too far away from the engine and cannot be regulated by people; and the operating handle has no misoperation protection safety measure; how to solve and how to prevent the occasional defects and shortcomings of a plurality of snow sweepers is always a long-standing problem in the field. In order to overcome the defects of working states caused by various mechanisms of the snow sweeper in the prior art and invent several different types of deicing snow sweepers, the inventor makes various designs and improvements; just as the spring silkworms are inexhaustible in silk death, the perfection of the invention pursued by human beings is ceaselessly, the inventor associates that the inventor works as SENIOR ENGI abroad such as Switzerland and the like and works high in domestic general work for decades to do the experience of hundreds of patents at home and abroad, and the inventor works a method, namely the original outer cover without the noise elimination effect is changed into two cavities with the noise elimination effect, and the three-cavity type noise eliminator becomes a five-cavity noise eliminator, so that the noise elimination effect is greatly improved, the cost is almost the same as that of the original outer cover, the temperature is reduced to about 120 ℃, the original grass cutter is used, and the installation position is slightly changed to be adapted to a snow sweeper and is still usable; if the temperature can be reduced to be lower than 100 ℃, the method is more ideal and safer; the manila has the advantages that the manila has a heat transfer steam groove and a front exhaust pipe, a more ideal and safe method is a steam groove method of safety measures of the manila, a groove added with water is used for covering a silencer so as to reduce the temperature, hot steam changed from the added water is guided to the front of snow sweeping through a steam pipe (16) so as to facilitate heat to assist in deicing, and the manila achieves two purposes; meanwhile, hot waste gas of the muffler is guided to the front of the snow sweeper through a waste gas pipe or a waste gas pipe (17) with a noise elimination function, so that the noise elimination effect is improved, auxiliary deicing is facilitated, waste gas which is originally too close to an operator and is not more than one meter from a waste gas outlet to a nose is discharged to a far place to be beneficial to health, the defect that partial waste gas is easily mixed into air inlet air of the air filter for the second time due to the fact that the waste gas outlet of a small gasoline engine is too close to the air filter inlet and is not more than 0.3 meter is overcome, and the effect of taking four things at a stroke can be achieved; snow is changed into ice and is directly difficult to remove, but when the snow ice meets hot steam and hot waste gas suddenly, the snow ice is heated locally and is easy to crack by impact, so that auxiliary deicing is facilitated, the whole ice is not required to be heated and melted, and the additional heating energy consumption is not required; the excessive heat and exhaust gas at the muffler are turned to the front where the local heating is needed, which is not easy to think, can be a skillful invention, is easy to implement in process and cost, checks a large number of similar patents at home and abroad, is innovation, perhaps speaking, the snow sweeper with the antiskid chain and the heat transfer steam groove and the front exhaust pipe is created, the single-tooth-disc variable-speed snow sweeper is further invented, the defect of slippage of a friction disc of a common snow sweeper is fundamentally overcome, on the basis of a novel snow sweeper with an anti-skid chain, an ice tooth snow brush auger, a heat transfer steam tank and a front exhaust pipe, which is improved by a common snow sweeper, the snow sweeper is further perfected as a single-fluted disc variable-speed snow sweeper with a safety control and front auxiliary wheel and a noise reduction machine body, and a new technical field of single-fluted disc variable-speed walking machinery with cooling, noise reduction, energy conservation and emission reduction is created. Although snow sweeping is just as good as possible, new problems arise; what is the purpose of snow sweeping? Is used for sweeping a road convenient for people to walk; however, the problem is that thick snow on the road is swept, but because the snow is not swept cleanly, a thin layer is left on the road, and because of treading or sun drying, melting, freezing and the like, the thin layer left on the road becomes an ice and snow mixed layer, so that the road is very smooth, the walking safety is influenced, and the hard side and the smooth side are difficult to remove; how to use the mechanical snow sweeping and the ice and snow removing mixed layer is a long-standing problem which is difficult to solve by the mechanical snow sweeping machine. If a snow blower, a snow sucker or a vibrator and the like are adopted, the power machine is far and inconvenient to drive, and the market forecast and the actual need of a snow sweeper driven by an engine and a motor are developed so as to be gradually improved and continuously innovated.

It is preferable to implement rules on mass-produced snow plows using the suggestions and methods of the present invention.

Without the full beauty, any product will always have many deficiencies to be further improved, as the invention is never at all. Because the invention is divided into two steps to walk, a common snow sweeper is improved into a novel snow sweeper with an anti-skid chain, an ice tooth snow brush auger, a heat transfer steam tank and a front exhaust pipe, so the snow sweeper is firstly said; on the basis of the prior art, the snow sweeper with the single-toothed disc variable multi-speed and the safety operation and the front auxiliary wheel and the noise reduction machine body is further improved.

However, any product is not perfect, and always has many defects to be further improved. The common snow sweeper mostly adopts a horizontal air-cooled small gasoline engine, the temperature rise of a silencer shell is too high, the temperature of the silencer shell is 160 ℃, the safety is affected, the silencer shell does not reach the standard, improvement is urgently needed, the improvement is difficult to overcome, and a plurality of enclosure with a railing net shape without the silencing effect are only added by a cumbersome method. Mufflers are widely used as muffling devices for internal combustion engines, particularly small gasoline engines, and are mounted on the exhaust port of the cylinder head to reduce noise during operation of the engine. The limit value of noise of various walking vehicles, garden machines such as grass mowers, rotary tillers, snow plows and the like and farming and animal husbandry machines is regulated in all countries around the world, and the exhaust muffler is a device for reducing exhaust noise. The performance evaluation of the silencer mainly has the indexes of acoustic performance, aerodynamic performance, structural performance and the like. A considerable part of the internal combustion engine belongs to a pulsating low-frequency noise source, and a reactive or impedance complex and a micropore plate silencer are mostly adopted. The common silencer of the internal combustion engine, particularly the silencer used for a small gasoline engine, is mostly a three-cavity silencer, and has limited silencing effect; and the exterior needs to have a larger protective outer cover, as shown in the outer cover 19b of the snowplow three-dimensional schematic diagram of fig. 7, but the outer cover does not have the noise elimination function, the temperature rise of the outer cover is ultrahigh, various machine types are common, the snowplow is not only a snowplow, but also a mower, although the noise eliminator is provided with the outer cover, the appearance is good, the ears of the deaf person are actually arranged, the snowplow is not too top-mounted, the mowers are scalded, the safety is influenced, and the problem cannot be thoroughly solved. Snow plows encounter many situations: sometimes, when snow is swept, particularly when the snow and ice are mixed, or when the road conditions are poor, various defects of the original snow sweeper do not occur much or little, such as: the auger and the snow shoveling plate of the ice-tooth-free snow brush in front of the snowplow sometimes have insufficient snow entering; the throwing effect of the snow throwing disc is not obvious and not far; the rotation direction of the snow outlet is not freely used sometimes; the small ice and snow spade without teeth is not good when meeting a little thin ice; the front side of the snow sweeper is difficult to push when the snow sweeper turns in a sharp bend because of no front side steering gear like the front auxiliary wheel 14a or the front crawler 14; the large walking wheels without the antiskid chains skid along the ground, and can not push snow forward well; even if the hand gripping the pull rope handle is painful, the hand cannot hold the pull rope handle; still like the snowplow type fence 24 of fig. 7, too far from the engine, one cannot reach the engine's regulation; and the operating handle has no misoperation protection safety measure; how to solve and how to prevent the occasional defects and shortcomings of a plurality of snow sweepers, or the technical phenomena which are hidden or present but not present, is a great problem in various fields. The invention aims to overcome the defects of working states of various mechanisms of the snow sweeper in the prior art, and invent a plurality of novel deicing snow sweeper, a mani made of polished tiles and a mani, and the inventor pursues perfection and never stops when the inventor looks like spring silkworms to be dead. The heat transfer steam groove and the front exhaust pipe are arranged, so that heat transfer is facilitated; the ice shoveling plate 15 arranged at the front lower part of the machine body is toothed, so that ice and snow are conveniently shoveled; a front exhaust pipe 17 which is used for melting ice and is ventilated to the front lower part of the machine body and a hot steam pipe 16 which is used for melting ice and is ventilated to the front lower part of the machine body are arranged beside the ice shoveling plate 15, so that the ice is easy to be locally heated and is easy to break; a heat transfer steam groove 19 is arranged at the periphery of a silencer 12 of the engine, the heat transfer steam groove is a container for adding water, the specific heat of the water is large, so the temperature is favorably reduced, and a heat steam pipe 16 is arranged on the heat transfer steam groove and used for introducing heat steam to a heat steam pipe for melting ice in the front lower part of the engine body; and the exhaust gas outlet of the silencer 12 of the engine is connected with a front exhaust pipe 17 which leads the exhaust gas to the front exhaust pipe for deicing in the front lower part of the engine body, thus being beneficial to heat transfer and assisting in deicing.

Besides the grabbing and grabbing adhesion capability of the antiskid chain, the counterweight also has a great influence on the grabbing and grabbing adhesion capability of the antiskid chain; as the heat transfer steam tank is filled with water, the weight of the heat transfer steam tank is variable and adjustable, the volume of a container influencing the balance weight needs to be calculated, and when the water is added more, the grabbing and scraping adhesion capacity of the antiskid chain is large, which is self-evident and has a great influence on the walking antiskid of the whole machine. The second major characteristic of the water-added heat transfer steam tank influences the traveling of the whole machine such as turning and ascending and descending, especially the height of the center of gravity of the tank is required to be noticed, and the longitudinal potential stability coefficient is calculated. In other words, the heat transfer steam tank is suitable, the container is slightly larger, and the amount of water added is better.
