Description

Technical Field

[0001] The present invention relates to a snow melting and removing machine for areas with little snowfall.

Background Art

[0002] In areas with little snowfall such as the city center, a snow melting system as urban infrastructure such as snow melting pipes is not well - equipped, and the installation of snow removal equipment in homes and workplaces is also insufficient. For this reason, when snow falls and freezes, it causes traffic disruptions and accidents. Even in large urban areas such as the southern Kanto region, which have not taken snow - accumulation countermeasures in the past, they have been hit by sudden snowfalls several times a year in recent years. In these areas, there is a lack of snow -fall countermeasures as urban infrastructure, and the residents are not used to snow, so even a small amount of snowfall has a great impact on business and life. Also, snow shovels and scoops are suitable for shoveling and disposing of a large amount of snow in places with heavy snowfall, but when there is little snowfall or when dealing with partial snow accumulation, they will come into contact with the ground and damage the equipment itself. When the ground is other than soil such as asphalt, the ground side will also be damaged. In addition, these equipment are suitable for snow removal work on wide surfaces such as roads, but are not in a shape suitable for dealing with a small amount of snow accumulation in narrow places such as sidewalks and in front of entrances. Therefore, at present, sufficient snow melting infrastructure and equipment have not spread for sudden and small amounts of snow accumulation in areas with little snowfall. As a method of melting snow for a small amount of snow accumulation or snow deposition, methods using IH or warm air can be considered. Since these methods do not bring the snow melting machine itself into contact with the snow or the ground, equipment damage can be avoided.

[0003] At construction sites, the snow that gradually accumulates on the steel plates laid for heavy machinery to travel on, as well as at the boundaries between the footpaths and roadways inside and outside the construction site, makes it easy for construction workers to slip and fall, causing injuries and work-related accidents. However, since construction sites are completed and handed over within about one to two years, and the materials and temporary facilities used in the construction are removed, it is impossible to introduce snow melting pipes or geothermal snow melting systems that are used as social infrastructure due to the installation man-hours and cost-effectiveness for the frequency of use. For snow melting in small areas, it is possible to lay snow melting mats that use conventional power sources. However, for a small amount of snowfall, they often continue to operate even after the snow has melted, resulting in wasted power consumption and is not a practical solution.

[0004] On the pedestrian passageways in the outdoor parking lots of large commercial facilities and on the passageways from the parking lots to the entrances of small-scale hospitals, even the small amount of snow accumulation on asphalt or brick-paved footpaths can cause people to slip. Even in these existing facilities, installing snow melting pipes, geothermal snow melting systems, or introducing snow melting mats that use conventional power sources for the snow accumulation that occurs several times a year is not efficient in terms of cost and maintenance management.

[0007] One object of the present invention is to provide an efficient snow melting and removing machine for a small amount of snow accumulation. Another object of the present invention is to prevent re-freezing of snow at the same location after snow melting by providing a snow melting and removing machine that removes the remaining snow after snow melting.

Means for Solving the Problems

[0008] According to one aspect of the present invention, A snow melting and removing machine (100) that travels on the ground including snow accumulation such as on the steel plates at a construction site or on the pedestrian passage of an outdoor parking lot, A snow melting mechanism (110) for melting the snow accumulation on the ground, A snow removing mechanism (120) for melting the snow accumulation and discharging the snow water generated after melting, A subdivision mechanism (820) for facilitating the drainage of the snow that is not completely melted by the snow melting mechanism (110) and remains in a semi-melted state, A snow removing mechanism (330, 830) for discharging the snow water generated after melting by the snow melting mechanism (110) and the tiny melted snow generated after subdivision by the subdivision mechanism (820), Including the above, the snow removing mechanism (120), A moving mechanism (130) for mounting and moving the snow melting mechanism (110) and the drainage mechanism (330, 830), A snow melting and removing machine (100) is provided, characterized in that it is provided with the above. According to another aspect of the present invention, The snow melting mechanism (110) is installed in front with respect to the traveling direction of the moving mechanism (130), and the snow removing mechanism (120) is installed behind the snow melting mechanism (110) of the snow melting and removing machine (100) in the traveling direction, so that snow removal is performed after snow melting with respect to the traveling direction of the snow melting and removing machine (100). The snow melting and removing machine (100) according to claim 1, characterized in that. According to another aspect of the present invention, The snow melting mechanism (110) includes an arbitrary heat source (210), The drainage mechanism (330, 830) is a plate-shaped snow removal plate (330, 830), and is installed obliquely behind the snow melting mechanism (110) of the snow melting and removing machine (100) in the traveling direction, After the snow is melted by the heat source (210), the semi-molten snow is fragmented by the fragmentation mechanism (820), and snow removal is performed by the snow removal plates (330, 830). That is, snow melting and snow removal are performed by a plurality of mechanisms according to the process of changing the state of snow from an individual to a liquid, and a snow melting and snow removal machine (100) is provided. According to another aspect of the present invention, The fragmentation mechanism (820) is a snow removal brush (820) formed in a brush shape, A snow melting and snow removal machine (100) is provided, which is characterized in that it is installed on the lower surface side of the snow melting and snow removal machine (100) so that the lower part of the snow removal brush (820) contacts the ground. According to another aspect of the present invention, The snow removal brush (820) is installed such that the upper part having the attachment portion is on the front side with respect to the traveling direction, and the lower part having the portion in contact with the ground is on the rear side. According to another aspect of the present invention, A snow melting and snow removal machine (100) is provided, wherein the upper part of the snow removal brush (820) is soft, the lower part is harder and heavier than the upper part, and when passing through the unevenness of the ground in the traveling direction, the soft upper part is configured to bend along the unevenness. According to another aspect of the present invention, A temperature sensor (601) is installed between the snow melting mechanism (110) and the snow removal mechanism (120), A snow melting and snow removal machine (100) is provided, wherein the temperature sensor (601) detects an increase in the surface temperature of the road surface, determines that it is in a semi-molten state without complete melting, and determines whether it is possible to shift to snow removal by the snow removal mechanism. According to another aspect of the present invention, The snow melting and snow removal machine (100) is provided with a warping plate that travels on the snow before snow melting by the snow melting mechanism (110), and the front wheels in front of the moving mechanism (130) are configured to be able to travel and change direction on the snow by the warping plate.

[0009] Therefore, in one aspect of the present invention, while the snow melting and removing machine advances against the snow in front, it is possible to perform snow melting in the front, fragmentation in the middle part, and drainage in the rear.

[0010] When looking at the changes given to the snow by the front, middle, and rear mechanisms as the snow melting and removing machine of one aspect of the present invention advances, from the snow side, first, it starts to melt by receiving the heat irradiation from the snow melting mechanism and all or part of it becomes water. Some of the snow that is compacted or far from the heat source on the ground does not completely melt into water. At this time, the snow is evenly heated from the upper part to the inside by IH, and the water generated by melting soaks into the surrounding snow. The snow under the snow melting mechanism that receives the IH irradiation is in the state of snow water. The snow of the snow melting and removing machine is melted by receiving the IH irradiation from the snow melting mechanism, and after the remaining unmelted snow has a reduced volume in the height direction and a gap is generated, it passes through the fragmentation mechanism in the middle part. The snow with a gap generated by the snow melting mechanism is scattered by the fragmentation mechanism into fine ice particles, and when the ground under the snow is warmed by the IH irradiation of the snow melting mechanism, it also receives heat from the ground and melts into water or a sleet state close to water. When the snow melting and removing machine further advances, the snow that has become water or a sleet state close to water is drained in the drainage direction to either the left or right side or both sides indicated by the installation direction of the drainage mechanism.

[0011] After going through the above snow melting process, the part where there was snow becomes the ground where drainage is completed. In each embodiment of the present invention, the expression "ground" is used, but the surface on which the snow melting and removing machine touches the ground is referred to as the ground. For example, it may mean the surface on which snow has accumulated on an iron plate, or it may mean the surface on the iron plate after snow melting and removal. However, within the range that those skilled in the art can understand, the meaning of "ground" can be understood according to the situation.

[0012] In one aspect of the present invention, further, the direction of the drainage plate, which can be expected to enhance the absorption rate of far-infrared rays of the snow to be the next target of snow melting and snow removal using the drained water, is set to be the direction in which the drainage heads towards the snow that is the target of snow melting and snow removal when the snow melting and snow removal machine turns back. By doing so, water can be infiltrated into the snow melting target part in advance by the water sent through the drainage plate, and the melting by the snow melting mechanism can be assisted. As another effect that the direction of the drainage plate can be adjusted so as to send water into the snow that is the next target of snow melting and snow removal, it is possible to prevent the drained water from flowing into the place where snow melting has been completed again and refreezing.

[0013] In one aspect of the present invention, in order to make the mechanism arrangement such that the snow melting and snow removal machine does not interfere with the IH irradiation towards the snow of the snow melting mechanism, the rearmost part of the snow melting mechanism is arranged to protrude forward of the foremost part of the snow melting and snow removal machine. In order to prevent the entire mechanism from tilting forward due to the weight of the snow melting mechanism, auxiliary wheels may be installed in front of the snow melting mechanism. The auxiliary wheels can rotate 360 degrees in the horizontal direction to correspond to the straight movement and direction change of the entire mechanism. In order to travel on the snow before snow melting by the snow melting mechanism, a warping plate with a warped end is installed around the turning radius of the auxiliary wheels. The warping direction of the warping plate is warped on the side far from the auxiliary wheels and can ride on the snow, and it can crush the snow up to the snow accumulation height where the auxiliary wheels are not buried in the snow. The warping plates are installed in each of the front, rear, left, and right directions to correspond to forward movement and direction change. When it is necessary to further reduce the resistance due to snow during turning, they are installed in the diagonally forward left and right and diagonally backward left and right directions. The gaps between the warping plates are filled with the same material as the warping plates or a water-resistant resin.

[0014] The snow melting and removing machine used in one aspect of the present invention may be electric. The electric power may be used to reduce the burden on the operator's hand when performing snow melting and removing operations using one aspect of the present invention as a hand-pushed machine, or may be used as the power for the present invention itself to perform automatic driving. When the snow melting and removing machine performs automatic driving, a temperature sensor is mounted between the snow melting mechanism and the snow removing mechanism as a mechanism for measuring the progress of snow melting by the snow melting mechanism and determining that the remaining snow volume, density, and hardness of the snow that can be swept by the subdividing mechanism have been reached. When the surface temperature of the snow is measured by the temperature sensor during the progress of snow melting according to one aspect of the present invention, the unmelted state is the coldest. As water is generated in the snow as the snow melting progresses, the temperature rises. When the partial melting of the snow reaches the ground surface, the ground surface temperature, which is higher than the snow and the water after the snow melts, is measured. When the ground surface temperature is measured, it is determined that the density of the snow that can be scattered by the subdividing part has been reached, and a forward permission signal is given from the temperature sensor to the snow melting and removing machine. When the snow melting and removing machine receives the forward permission signal, it moves forward at a specified distance and speed. The specified distance, speed, and travel route for the snow melting and removing machine may be such that a color tape is laid before snow accumulation in the snow melting target range, and the color tape exposed by the snow melting of the snow melting mechanism is read using an image recognition sensor installed between the snow melting and removing machine and the snow melting mechanism as the travel route. Alternatively, landmarks such as triangular cones may be learned in advance as travel route landmarks by machine learning, and the travel route may be to cover the inside of the triangular cone range at a specified distance, speed, and turning angle.

[0015] The power source for operating the snow melting and removing machine, the snow melting mechanism, the temperature sensor, the image recognition sensor, and the operation panel that integrates them used in one aspect of the present invention is a large-capacity battery mounted on the upper part of the snow melting and removing machine.

Advantages of the Invention

[0016] With the snow melting and removing machine of the present invention, efficient snow melting and removing for small areas and small amounts of snow accumulation becomes possible. In addition, it prevents snow accumulation at night, leading to a reduction in the risk of falling when entering a construction site or the entrance of an office in the early morning, and it is possible to prevent work delays by reducing the snow removal work before the start of work. Other objects, features, and advantages of the present invention will become apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

Mode for Carrying Out the Invention

[0018] Figures 1A and 1B show the configuration of a snow melting and removing machine according to an embodiment of the present invention. The snow melting and removing machine 100 of this embodiment includes a snow melting mechanism 110 that serves as an IH irradiation source for snow melting, a snow removing mechanism 120 that removes the snow that remains partially melted after the snow melting by the IH irradiation of the snow melting mechanism 110, a crawler unit 130 for moving the snow melting and removing machine 100 forward and changing its direction, a front wheel unit 140 that prevents the forward tilt due to the weight of the snow melting mechanism 110 and supports forward movement and direction change, an operation panel 150 for an operator to control the traveling of the snow melting and removing machine 100, a handrail 160 for the operator to push the snow melting and removing machine 100 forward, a control device 170 for enabling information communication and operation instructions between the snow melting mechanism 110, the crawler unit 130, and the operation panel 150, and a large-capacity battery 180 that supplies power to the heater unit 210, the crawler unit 130, the operation panel 150, and the control device 170. In this embodiment, as the power source of the heater unit, a large-capacity battery is used instead of fossil fuel, but any power source may be used. 101 is a side view from the control device 170 side of the snow melting and removing machine 100.

[0019] Figure 2 shows the configuration of the snow melting mechanism according to an embodiment of the present invention. The snow melting mechanism 110 is a mechanism that causes uniform snow melting reduction in both the planar direction and the depth direction in the snow located below the snow melting mechanism 100, and may be a snow melting source such as an IH (Induction Heating) heater, for example. The battery unit (not shown) only needs to be able to supply sufficient power to the heater unit 210, and may be any energy source other than a battery. The cover unit 220 is a metal reflector that covers the periphery of the heater unit 210, and the heat radiated from the heater unit 210 is reflected and deflected by the cover unit 220 so as to be concentrated on the opening 221 side of the heater unit 210. In the snow melting and removing machine 100, snow melting is performed by directing the opening 221 of the snow melting mechanism 110 downward. Further, the power supply unit 230 is connected to the large-capacity battery 180 and supplies power for operating as a snow melting source to the heater unit 210.

[0020] Figs. 3A and 3B show the configuration of the snow removal mechanism 120 according to an embodiment of the present invention. For convenience of explanation, Fig. 3 includes other mechanisms adjacent to the snow removal plate 330. Also, it is assumed that the snow removal using the snow removal mechanism 120 is performed by advancing the snow removal mechanism 120 by the crawler unit 130, and in the following description of snow removal by the snow removal plate 330, the description of the forward movement is omitted. The snow removal mechanism 120 is installed behind the snow melting mechanism 110 in the snow melting and removal machine 100, and discharges the snow softened by the snow melting mechanism to the side. By combining the snow melting by the snow melting mechanism 110 and the snow removal by the snow removal mechanism 120, the snow melting mechanism 110 does not reach complete melting for the snow to be melted in the front, but only melts it to an amount and density that allows the snow to be pushed away by the snow removal plate 330, and the heat irradiation time and the amount of electric power required for heat irradiation can be reduced. Also, from the perspective of the snow removal efficiency of the snow removal mechanism 120, since the object of snow removal is not snow where no snow melting and removal is performed, but snow softened and partially liquefied by the snow melting mechanism 110, the snow removal plate height required for snow removal and the energy required for forward movement can be reduced. Therefore, the snow melting mechanism 110 and the snow removal mechanism 120 can efficiently remove snow due to the synergistic effect of snow melting and snow removal. The snow removal mechanism 120 is connected by a connector 310 to a beam 320 attached in parallel with the snow melting mechanism 110 behind the snow melting mechanism 110 of the snow melting and removal machine 100, and the snow removal plate 330 is connected downward from the connector 310. For this reason, it is possible to adjust the snow removal direction of the snow removal plate 330 by moving and rotating the connector 310 on the beam 320. In addition to the equal snow removal to both sides in the traveling direction shown in the connector 310 of Fig. 3, it is also possible to install the snow removal plate 330 so that the snow removal direction is only in one of the left and right directions. The snow removal plate 330 is installed obliquely in the direction opposite to the traveling direction of the snow melting and removal machine 100 from the connector 310, and the snow removal plate 330 is curved so as to be closer to parallel to the ground from the base to the tip. The base of the snow removal plate 330 can be tilted backward with respect to the traveling direction by a connecting shaft 340. Due to the backward curvature of the snow removal plate 330 and the movable mechanism of the connecting shaft 340, when the snow melting and removal machine 100 advances after snow melting by the snow melting mechanism 110, the snow removal plate can advance without being caught by obstacles such as stones or unevenness of the road surface.The crawler unit 130 is an electric traveling machine that receives power supply from the large-capacity battery 180 and travels. Its shape is, for example, a crawler type, and one unit is installed at each of the left and right positions when looking at the side where the snow melting mechanism 110 of the snow melting and removing machine 100 is installed as the front.

[0021] Figures 4A and 4B show the configuration of the front wheel unit 140 according to an embodiment of the present invention. The front wheel unit 140 is composed of a connecting shaft 141, a wheel 142, and a skid plate 143, and is an auxiliary wheel mechanism that also serves as a support column for preventing the snow melting mechanism 110 from tilting forward due to the weight of the snow melting mechanism 110, and is connected directly below the tip portion 1010 of the snow melting mechanism 110. The wheel 142 is a passive wheel that can rotate 360 degrees in the horizontal direction, and moves forward and turns in accordance with the behavior of the crawler unit 130. The skid plate 143 is a dish-shaped plate that surrounds the outside of the wheel 142 and is fixed by a support column that extends outside the turning radius of the wheel 142 from the support column. A hole with a circumference having the length of the long side of the wheel 142 as the diameter is opened at the center of the skid plate 143, and the wheel 142 is installed with its center aligned with the center of this hole. The skid plate 143 is installed at a height where the lower end is lower than the vertical center of the wheel 142 and does not contact the ground, and pushes down the snow before snow melting existing in the traveling direction and turning direction of the wheel 142, enabling the wheel 142 to travel.

[0022] Figures 5A to 5I show the flow of snow melting and snow removal using the snow melting and removing machine 100 according to an embodiment of the present invention. In Figure 5, 510 indicates the accumulated snow before snow melting, and 520 indicates the snow after snow melting by the snow melting and removing machine. The snow after snow melting is a state in which the water generated by melting by the snow melting mechanism 110 and the snow softened in a semi-melted state are mixed.

[0023] Before the snow melting starts by the snow melting and removing machine 100, as shown in 5010, the snow 510 before snow melting exists on the entire surface of the snow melting and removing machine 100. The snow melting and removing machine 100 advances by the driving force of the crawler unit 130, the front wheel unit 140 pushes down the snow 510 before snow melting and advances, and after reaching the state of 5020 where the rearmost part of the snow melting mechanism 110 reaches the snow 510 before snow melting and stops, the snow melting mechanism 110 receives power supply from the large-capacity battery 180 to perform snow melting. The snow 510 before snow melting located below the snow melting mechanism 110 is melted into the state of the snow 520 after snow melting, and the front of the snow melting and removing machine 100 becomes the state of 5030.

[0024] The snow melting and removing machine 100 advances as shown in 5010 - 5020 for melting the snow 510 before snow melting. At the time point of 5010, the snow melting and removing machine 100 enters in front of the snow 510 before snow melting. At the time point of 5020, the snow melting and removing machine 100 enters onto the snow 510 before snow melting and starts snow melting. The snow 520 after snow melting at the time point of 5030 is removed to the side by the snow removing mechanism 120 and becomes the state of 5040. By continuously performing the process of 5010 - 5040 on the snow 510 before snow melting in the advancing direction, the snow 510 before snow melting is removed to the side of the snow melting and removing machine 100 as the snow 520 after snow melting. Also, the snowmelt water melted by the snow melting mechanism 110 is drained to the side of the snow melting and removing machine 100 by the snow removal plate 330, and a part remains as water below the snow melting and removing machine 100.

[0025] Figure 6 shows the second embodiment of the present invention, which is an example for automatically melting snow using the snow melting and removing machine 100. 601 is a temperature sensor, for example, a radiation thermometer. The temperature sensor 601 is installed at a position behind the snow melting mechanism 110 and in front of the snow plow 330, measures the temperature of the snow below the snow melting mechanism 110 with a radiation thermometer, and detects the rise in the ground surface temperature (the surface temperature of the road surface) that is warmed by passing through the surface of the snow. By doing so, it is determined by a determination mechanism (not shown) that the snow melting has been completed up to the semi-melted state of the snow, and the status is transmitted to the control device 170 as a forwardable state (that is, a state in which it is possible to shift to snow removal by the snow removal mechanism). 602 is an image sensor, which detects the marks on the ground after the snow removal by the snow plow 330 and transmits it to the control device 170. In the control device 170, the next traveling direction is determined based on the forwardable determination information transmitted from the temperature sensor 601 and the direction of the marks transmitted from the image sensor 602, and the traveling direction is transmitted to the crawler 130. In the crawler unit 130, based on the traveling direction information given from the control device 170, it moves the whole body corresponding to the front and rear of the snow melting mechanism 110. When the traveling direction information transmitted from the control device 170 to the crawler unit 130 is a turn, the crawler unit 130 makes a turn at the given angle. By continuously performing the control of this embodiment, the snow melting and removing machine 100 can automatically perform snow melting and snow removal in the target area.

[0026] Figure 7 shows an example of the installation of a detection marker for detecting a traveling route using the image sensor 602 for automatically melting snow by the snow melting and removing machine 100 according to the second embodiment of the present invention. In this installation example, a white line or a white tape is laid in advance in the target range of snow melting and snow removal before snowfall. After the snow accumulates, after the snow melting by the snow melting and removing machine 100, the determination of the completion of forward movement by the temperature sensor 601, and the snow removal by the snow plow 330, the white tape that is exposed is detected by the image sensor 602 and the vehicle travels.

[0027] FIG. 8 shows a third embodiment using the snow melting and removing machine 100 according to an embodiment of the present invention, which is an embodiment for further strengthening the snow removing mechanism according to the embodiment shown in FIG. 1 of the snow melting and removing machine 100. In the embodiment of the snow melting and removing machine 100, when the snow melting capacity of the snow melting mechanism 110 is insufficient or when it is desired to complete snow melting and snow removing in a shorter time, this embodiment can be used to improve the snow melting and removing capacity and efficiency of the snow melting and removing machine 100. The snow melting and removing machine 800 is an embodiment diagram in which the options in this embodiment are added to the snow melting and removing machine 100. It extends downward behind the snow melting mechanism 110 or is mounted on the frame between the snow melting mechanism 110 and the snow removing mechanism 120 to add a subdividing mechanism 820, and a rear wheel bumper 810 is added to the frame between the snow removing mechanism 120 and the crawler unit 130. The snow melting and removing machine subdividing mechanism 820 is in the shape of comb teeth, and is installed so that the lower end is dragged as the snow melting and removing machine moves forward and is located behind the upper end, and has a weight and hardness capable of scraping apart semi-melted snow. The rear wheel bumper 810 is installed in a position not in contact with the crawler unit 130 in the traveling direction and has an acute angle shape facing the traveling direction.

[0028] The subdividing mechanism 820 is a subdividing mechanism for facilitating the drainage of snow that remains in a semi-melted state without being completely melted by the snow melting mechanism 110. The subdividing mechanism 820 is a comb-like mechanism made of a soft resin such as plastic. As shown in FIG. 8, by being configured to contact the ground behind the snow melting mechanism 110, it reaches the snow that has become semi-melted by the snow melting mechanism 110 as the crawler unit 130 advances, and exerts a peeling effect and a horizontal cutting effect on the semi-melted snow, especially on the compacted snow and the deposited snow. This improves the snow removal efficiency of the rear snow removal mechanism 120 and reduces the local load on the lower part of the snow removal mechanism 120. The subdividing mechanism 820 is installed such that the lower part with the attachment part is on the front side with respect to the traveling direction of the snow melting and removing machine 100, and the upper part with the part in contact with the ground is on the rear side, so it does not obstruct or get caught during the advancement of the snow melting and removing machine 100. Furthermore, since the upper part of the subdividing mechanism 820 is soft and the lower part is harder and heavier than the upper part, when passing over the unevenness of the ground with respect to the traveling direction of the snow melting and removing machine 100, the soft upper part bends along the unevenness, and while avoiding getting caught, it can surely scatter the snow by applying the weight and hardness of the lower part to the snow.

[0029] The rear wheel bumper 810 has a function of further crushing the snow even when the snow melting by the snow melting mechanism 110 of the snow melting and removing machine is incomplete. Therefore, by using the subdividing mechanism 820 and the rear wheel bumper 810 as options, it is possible to shorten the snow melting time by the snow melting mechanism 110, and it becomes possible to make the forward travel determination from a lower temperature when making the forward travel determination using the temperature sensor 601, and the operating time is also shortened in the case of automatic driving.

[0030] In FIG. 8, the snow compaction removal plate 810, the rear wheel bumper 815, and the snow removal plate 840 are shown above the frame constituting the snow melting and removing machine 800 for the purpose of shape explanation, but they may be installed below the frame when actually implementing the present invention.
