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. Therefore, when snow falls and freezes, it causes traffic chaos and accidents. Even in large urban areas such as the southern Kanto region where there has been no snow - removal measures 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 residents are not used to snow. 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. However, when dealing with little snowfall or 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 devices 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 the entrance of a house. 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 contact the snow melting machine itself with the snow or the ground, equipment damage can be avoided. 【0003】 At construction sites, the light layer of snow that accumulates on the steel plates used for heavy machinery, and at the boundary between the construction site and sidewalks or roads outside the site, can easily cause construction workers to slip, leading to injuries and workplace accidents. However, since construction sites are completed and handed over in about one to two years, and the materials and temporary structures used in the construction are removed, it is not feasible to introduce snow-melting pipes or geothermal snow-melting systems, which are used as social infrastructure, due to the cost-effectiveness relative to the installation work and frequency of use. For snow melting in small areas, one option is to lay down snow-melting mats that use conventional power sources, but for small amounts of snowfall, they often continue to operate even after the snow has melted, resulting in dry heating and wasted electricity, making them an unrealistic solution. 【0004】 Even in pedestrian walkways in the outdoor parking lots of large commercial facilities and pathways leading from parking lots to entrances of small hospitals, light snowfall on asphalt or brick-paved sidewalks can cause slips. Installing snow-melting pipes, geothermal snow-melting systems, or conventional snow-melting mats for the sake of occasional snowfall is not efficient from a cost and maintenance perspective. 【0005】 Examples of prior art relating to the present application include the following patent documents. [Prior art documents] [Patent Documents] 【0006】 [Patent Document 1] Registration No. 3169432 [Patent Document 2] Registration No. 3209344 [Patent Document 3] Japanese Patent Publication No. 2004-232271 [Overview of the Initiative] [Problems that the invention aims to solve] 【0007】 One objective of the present invention is to provide an efficient snow-melting machine for small amounts of snowfall. Another objective of the present invention is to prevent refreezing of snow in the same location after melting by providing a snow-melting machine that removes snow that remains unmelted after melting. [Means for solving the problem] 【0008】 According to one aspect of the present invention, A snow melting machine (100) that travels on the ground including snow, such as on steel plates at construction sites or on pedestrian walkways in outdoor parking lots, A snow melting mechanism (110) for melting snow on the ground, A snow removal mechanism (120) that melts snow and removes snowwater generated after melting, A subdivision mechanism (820) for facilitating the drainage of snow that is not completely melted by the snow melting mechanism (110) and remains in a partially melted state, A snow removal mechanism (330, 830) removes snowwater generated after melting by the snow melting mechanism (110) and minute melted snow generated after fragmentation by the fragmentation mechanism (820), The snow removal mechanism (120) includes, A moving mechanism (130) for moving the snow melting mechanism (110) and the drainage mechanism (330, 830) is provided, The present invention provides a snow melting and removal machine (100) characterized by being equipped with the following. According to another aspect of the present invention, The snow melting mechanism (110) is installed in front of the direction of travel of the moving mechanism (130), and the snow removal mechanism (120) is installed behind the snow melting mechanism (110) in the direction of travel of the snow melting machine (100), thereby enabling snow removal after snow melting in the direction of travel of the snow melting machine (100), as described in claim 1. According to another aspect of the present invention, The snow melting mechanism (110) is equipped with an arbitrary heat source (210), The drainage mechanism (330, 830) is a plate-shaped snow removal plate (330, 830) and is installed diagonally behind the snow melting mechanism (110) of the snow melting machine (100) in the direction of travel. The present invention provides a snow melting and snow removal machine (100) characterized in that, after melting snow with the heat source (210), the partially melted snow is subdivided by the subdivision mechanism (820), and the snow is removed by the snow removal plates (330, 830), that is, snow melting and snow removal is performed by multiple mechanisms according to the process of the snow changing state from solid to liquid. According to another aspect of the present invention, The aforementioned subdivision mechanism (820) is a snow removal brush (820) formed in a brush shape, The present invention provides a snow melting machine (100) characterized in that the lower part of the snow removal brush (820) is installed on the lower side of the snow melting machine (100) such that the lower part of the snow removal brush (820) is in contact with the ground. According to another aspect of the present invention, The snow removal brush (820) is installed so that the upper part having the mounting portion faces forward in the direction of travel, and the lower part having the portion in contact with the ground faces backward. According to another aspect of the present invention, The present invention provides a snow removal machine (100) characterized in that the upper part of the snow removal brush (820) is soft, the lower part is harder and heavier than the upper part, and the upper soft part is configured to bend along the unevenness of the ground when passing over unevenness in the direction of travel. 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). The snow removal machine (100) is characterized in that the temperature sensor (601) detects a rise in the surface temperature of the road surface, determines that the snow is in a semi-melted state without completely melting, and determines whether it is possible to proceed to snow removal by the snow removal mechanism. According to another aspect of the present invention, The snow melting machine (100) is characterized in that it is equipped with a curved plate that travels on the snow before the snow melting mechanism (110) melts the snow, and the front wheels of the moving mechanism (130) are configured to be able to travel and change direction on the snow by the curved plate. 【0009】 Therefore, in one aspect of the present invention, the snow melting machine can move forward towards the snow in front of it, melt the snow in the front, break it up in the middle, and drain it at the rear. 【0010】 In one aspect of the present invention, when the snow is moved forward, the changes that the front, middle, and rear mechanisms impart to the snow are observed from the snow's perspective. First, the snow begins to melt upon receiving heat irradiation from the snow-melting mechanism, and all or part of it turns into water. Some compacted snow and snow on the ground far from the heat source do not completely melt into water. At this time, the snow is heated evenly from the top to the inside by the IH, the resulting water seeps into the surrounding snow, and the snow that receives IH irradiation under the snow-melting mechanism becomes snowmelt. The snow in the snow-melting machine is melted by the IH irradiation from the snow-melting mechanism, and the remaining snow decreases in volume in the height direction and gaps are created before passing through the intermediate subdivision mechanism. The snow with gaps created by the snow-melting mechanism is swept away by the subdivision mechanism and becomes tiny ice particles. If the ground beneath the snow has been warmed by the IH irradiation from the snow-melting mechanism, the snow also receives heat from the ground and melts into water or sleet that is close to water. As the snow-melting machine moves further forward, the water or slushy snow is drained in the direction of drainage, either to the left or right, or to both sides, as indicated by the installation direction of the drainage mechanism. 【0011】 After the snow melting process described above, the area where the snow was located becomes ground with drainage completed. In each embodiment of the present invention, the term "ground" is used, but it refers to the surface on which the snow melting machine makes contact with the ground. For example, it may mean the surface on which snow accumulated on the steel plate, or it may mean the surface on the steel plate after snow melting and removal. However, the meaning of "ground" can be understood by those skilled in the art, depending on the situation. 【0012】 In one aspect of the present invention, the direction of the drainage plate, which is expected to have the effect of increasing the far-infrared absorption rate of the snow to be melted next using the drained water, is set so that the drainage is directed towards the snow to be melted by the snow melting machine when it turns back. This allows the water sent through the drainage plate to permeate the snow to be melted in advance, thereby assisting the melting by the snow melting mechanism. Another effect of being able to adjust the direction of the drainage plate so that it sends water to the snow to be melted next is that it prevents the drainage from flowing back into areas where snow melting has been completed and causing refreezing. 【0013】 In one aspect of the present invention, the snow melting machine is positioned such that it does not obstruct the IH irradiation of the snow melting mechanism toward the snow. The rearmost part of the snow melting mechanism is positioned to protrude further forward than the frontmost part of the snow melting machine. 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 are rotatable 360 ​​degrees horizontally to accommodate the straight-line movement and turning of the entire mechanism. Curved plates with curved ends are installed around the auxiliary wheels outside their turning radius to allow them to travel on the snow before the snow melting mechanism melts the snow. The curved side of the curved plates is curved away from the auxiliary wheels, allowing them to ride up on the snow and crush the snow to a snow depth that does not bury the auxiliary wheels. The curved plates are installed facing forward, backward, left, and right to accommodate forward movement and turning. If it is necessary to further reduce resistance from snow during turning, they are installed facing diagonally forward and diagonally backward on the left and right. The gaps between each curved plate are filled with the same material as the curved plate 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 pushing when performing snow melting and removing using one aspect of the present invention as a hand-pushed machine, or may be used as the power for the one aspect of the present invention to perform automatic driving. When the snow melting and removing machine performs automatic driving, as a mechanism for measuring the progress of snow melting by the snow melting mechanism and determining that the remaining amount, density, and hardness of the snow that can be swept by the subdividing mechanism have been reached, a temperature sensor is installed between the snow melting mechanism and the snow removing mechanism. 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 un-melted 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 surface temperature, which is higher than the snow and the water after the snow melts, is measured. The fact that the surface temperature has been measured is determined to have reached the density of the snow that can be scattered by the subdividing unit, 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. Also, it may be a travel route that roams within the range of a triangular cone or the like by machine learning with a landmark such as a triangular cone as a travel route landmark in advance 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 these 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 a small area and a small amount of snow accumulation becomes possible. Also, 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. 【Brief Description of the Drawings】 【0017】 [Figure 1A] FIG. 1A shows a top view of the configuration of a snow melting and removing machine according to an embodiment of the present invention.

[Modes for carrying out the invention] 【0018】 Figures 1A and 1B show the configuration of a snow-melting machine according to one embodiment of the present invention. The snow-melting machine 100 of this embodiment consists of a snow-melting mechanism 110 which serves as an IH irradiation source for snow melting, a snow removal mechanism 120 which removes any remaining snow after it has been melted by the IH irradiation of the snow-melting mechanism 110, a crawler section 130 for moving the snow-melting machine 100 forward and changing direction, a front wheel section 140 which prevents the snow-melting mechanism 110 from tilting forward due to its weight and assists in moving forward and changing direction, an operation panel 150 for the operator to control the movement of the snow-melting machine 100, a push bar 160 for the operator to push the snow-melting machine 100 forward, a control device 170 which transmits information and operation instructions between the snow-melting mechanism 110 and the crawler section 130 and the operation panel 150, and a large-capacity battery 180 which supplies power to the heater section 210, the crawler section 130, the operation panel 150, and the control device 170. In this embodiment, a large-capacity battery is used as the power source for the heater section instead of fossil fuels, but any power source may be used. 101 is a side view of the snow melting machine 100 from the control equipment 170 side. 【0019】 Figure 2 shows the configuration of a snow melting mechanism according to one embodiment of the present invention. The snow melting mechanism 110 is a mechanism that causes uniform snow melting in both the planar and depth directions on the snow located below the snow melting mechanism 100, and may be a snow melting source such as an IH (Induction Heating) heater. 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 surrounds the heater unit 210, and the heat radiated from the heater unit 210 is reflected and deflected by the cover unit 220 so that it is concentrated toward the opening 221 of the heater unit 210. In the snow melting machine 100, snow melting is performed by directing the opening 221 of the snow melting mechanism 110 downwards. The power supply unit 230 is connected to a large-capacity battery 180 and supplies power to the heater unit 210 to operate as a snow melting source. 【0020】 Figures 3A and 3B show the configuration of a snow removal mechanism 120 according to one embodiment of the present invention. For the sake of explanation, Figure 3 includes the snow removal blade 330 and other adjacent mechanisms. Furthermore, it is assumed that snow removal using the snow removal mechanism 120 is performed by the crawler section 130 moving the snow removal mechanism 120 forward, and the description of snow removal by the snow removal blade 330 thereafter will omit the description of forward movement. The snow removal mechanism 120 is installed behind the snow melting mechanism 110 in the snow melting machine 100 and removes the snow softened by the snow melting mechanism to the side. By combining snow melting by the snow melting mechanism 110 and snow removal by the snow removal mechanism 120, the snow melting mechanism 110 does not reach complete melting of the snow to be melted in front, but only melts it to an amount and density that allows it to be pushed aside by the snow removal blade 330, thereby reducing the heat irradiation time and the amount of power required for heat irradiation. Furthermore, from the standpoint of snow removal efficiency of the snow removal mechanism 120, since the target of snow removal is not snow that has not undergone any snow melting or removal, but snow that has been softened and partially liquefied by the snow melting mechanism 110, the height of the snow removal blade 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 through the synergistic effect of snow melting and snow removal. The snow removal mechanism 120 is connected by a connector 310 to a beam 320 mounted parallel to the snow melting mechanism 110 behind the snow melting mechanism 110 of the snow melting machine 100, and the snow removal blade 330 is connected downward from the connector 310. Therefore, by moving and rotating the connector 310 on the beam 320, it is possible to adjust the snow removal direction of the snow removal blade 330, and in addition to even snow removal on both sides in the direction of travel as shown in the connector 310 of Figure 3, it is also possible to install the snow removal blade 330 so that the snow removal direction is only in either the left or right direction. The snowplow blade 330 is installed diagonally from the connector 310 in the opposite direction of travel of the snow removal machine 100. The snowplow blade 330 is curved so that it becomes nearly parallel to the ground from the base to the tip, and the base of the snowplow blade 330 can be tilted backward relative to the direction of travel by the connecting shaft 340. Due to the backward curvature of the snowplow blade 330 and the movable mechanism of the connecting shaft 340, the snow removal machine 100 can move forward after the snow has been melted by the snow melting mechanism 110 without the snowplow blade getting caught on obstacles such as stones or unevenness in the road surface.The crawler section 130 is an electric drive unit that runs on power supplied from a large-capacity battery 180, and is shaped like a crawler, for example, and is installed one on each side of the snow melting machine 100, when the side with the snow melting mechanism 110 is viewed as the front. 【0021】 Figures 4A and 4B show the configuration of the front wheel section 140 according to one embodiment of the present invention. The front wheel section 140 consists 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 to prevent the snow melting mechanism 110 from tilting forward due to its weight, 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 horizontally and moves forward and turns in accordance with the behavior of the crawler section 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 from the support column outside the turning radius of the wheel 142. The center of the skid plate 143 has a hole with a circumference equal to the length of the long side of the wheel 142 as its diameter, and the wheel 142 is installed with its center aligned with the center of this hole. The sled 143 is positioned so that its lower end is below the vertical center of the wheel 142 and does not come into contact with the ground. It pushes down the snow that is present in the direction of travel and turning of the wheel 142 before it melts, enabling the wheel 142 to move. 【0022】 Figures 5A to 5I show the snow melting and snow removal process using a snow removal machine 100 according to one embodiment of the present invention. In Figure 5, 510 shows the snow before melting, and 520 shows the snow after melting by the snow removal machine. The snow after melting is a mixture of water produced by melting by the snow melting mechanism 110 and snow that has been softened in a semi-melted state. 【0023】 Before the snow melting process by the snow removal machine 100 begins, snow 510 is present in front of the snow removal machine 100 as shown in 5010. The snow removal machine 100 moves forward with the propulsion of its crawler section 130, and its front wheels 140 push down the snow 510 as it moves forward. After the rear of the snow melting mechanism 110 reaches the snow 510 and stops, as shown in 5020, the snow melting mechanism 110 receives power from the large-capacity battery 180 to melt the snow. The snow 510 located beneath the snow melting mechanism 110 is melted and becomes snow 520, as shown in 5030, and the front of the snow removal machine 100 is in the state shown in 5030. 【0024】 The snow removal machine 100 moves forward from 5010 to 5020 to melt the snow 510 before melting. At 5010, the snow removal machine 100 has entered up to the front of the snow 510 before melting, and at 5020, the snow removal machine 100 has entered onto the snow 510 before melting and started melting it. At 5030, the melted snow 520 is removed to the side by the snow removal mechanism 120, resulting in the state at 5040. By continuously performing the process from 5010 to 5040 on the snow 510 before melting in the direction of travel, the snow 510 before melting is removed to the side of the snow removal machine 100 as melted snow 520. In addition, the meltwater from the snow melted by the snow melting mechanism 110 is drained to the side of the snow removal machine 100 by the snow removal plate 330, and some of it remains as water below the snow removal machine 100. 【0025】 Figure 6 shows a second embodiment of the present invention, which is an embodiment for automatically performing snow melting using a snow removal machine 100. 601 is a temperature sensor, for example, a radiation thermometer. The temperature sensor 601 is installed behind the snow melting mechanism 110 and in front of the snow removal blade 330. The radiation thermometer measures the temperature of the snow below the snow melting mechanism 110 and detects the rise in the ground temperature (road surface temperature) that is heated by passing through the surface of the snow. A determination mechanism (not shown) determines that snow melting to a semi-melted state is complete and transmits the status to the control device 170 as a state where it is possible to move forward (i.e., a state where it is possible to transition to snow removal by the snow removal mechanism). 602 is an image sensor that detects markers on the ground after snow removal by the snow removal blade 330 is completed and transmits this information to the control device 170. The control device 170 determines the next direction of travel based on forward movement determination information transmitted from the temperature sensor 601 and the direction of the marker transmitted from the image sensor 602, and transmits the direction of travel to the crawler 130. The crawler section 130 performs the entire front and rear of the snow melting mechanism 110 based on the direction of travel information provided by the control device 170. If the direction of travel information transmitted from the control device 170 to the crawler section 130 is a turn, the crawler section 130 performs a turn at the given angle. By continuously performing the control of this embodiment, the snow melting machine 100 can automatically melt and remove snow in the target area. 【0026】 Figure 7 shows an example of the installation of detection markers for detecting the travel route using an image sensor 602, for automatic snow melting by a snow removal machine 100 according to a second embodiment of the present invention. In this installation example, white lines or white tape are laid in advance in the area to be melted and removed before snowfall. After snowfall, the snow removal machine 100 melts the snow from the snow melting start point, the temperature sensor 601 determines when forward movement is complete, and the snow removal blade 330 removes snow. The image sensor 602 then detects the white tape that is exposed after these steps and guides the machine to travel. 【0027】 Figure 8 shows a third embodiment using the snow melting machine 100 according to one embodiment of the present invention, which is an embodiment that further enhances the snow removal mechanism of the snow melting machine 100 according to the embodiment shown in Figure 1. In the embodiment of the snow melting machine 100, if the snow melting capacity of the snow melting mechanism 110 is insufficient or if it is desired to complete snow melting and snow removal in a shorter time, this embodiment can be used to improve the snow melting and snow removal capacity and snow melting and snow removal efficiency of the snow melting machine 100. The snow melting machine 800 is an implementation drawing in which the options in this embodiment are added to the snow melting machine 100, with the rear of the snow melting mechanism 110 extended downward or attached to the frame between the snow melting mechanism 110 and the snow removal mechanism 120 to add a subdivision mechanism 820, and a rear wheel bumper 810 is added to the frame between the snow removal mechanism 120 and the crawler section 130. The snow-melting machine subdivision mechanism 820 has a comb-like shape, and is installed so that its lower end is dragged along by the forward movement of the snow-melting machine and is positioned behind its upper end. It also has the weight and hardness to separate partially melted snow. The rear wheel bumper 810 is positioned in the direction of travel and does not come into contact with the crawler section 130, and has a sharp angle in the direction of travel. 【0028】 The subdivision mechanism 820 is a subdivision mechanism designed to facilitate the drainage of snow that remains in a partially melted state and is not completely melted by the snow melting mechanism 110. The subdivision mechanism 820 is a comb-shaped mechanism made of a soft resin such as plastic, and as shown in Figure 8, it is configured to make contact with the ground behind the snow melting mechanism 110. As the crawler section 130 moves forward, it reaches over the snow that has been partially melted by the snow melting mechanism 110, and as it passes over the partially melted snow, especially compacted snow and accumulated snow, it exhibits a peeling effect and a horizontal cutting effect, thereby improving the snow removal efficiency of the rear snow removal mechanism 120 and reducing the local load on the lower part of the snow removal mechanism 120. The subdivision mechanism 820 is installed so that the lower part with the mounting portion is at the front in the direction of travel of the snow melting machine 100, and the upper part with the portion that contacts the ground is at the rear, so that it does not obstruct or get caught on the progress of the snow melting machine 100. Furthermore, since the upper part of the subdivision mechanism 820 is soft, and the lower part is harder and heavier than the upper part, when the snow melting machine 100 passes over uneven ground in the direction of travel, the upper soft part bends along the unevenness, avoiding snagging, and the weight and hardness of the lower part are applied to the snow to disperse it effectively. 【0029】 The rear bumper 810 has the function of further crushing snow even if the snow melting mechanism 110 of the snow removal machine is incomplete. Therefore, by using the subdivision mechanism 820 and the rear bumper 810 as options, the snow melting time by the snow melting mechanism 110 can be shortened, and the forward movement determination using the temperature sensor 601 can be made at lower temperatures, thus shortening the operating time even in autonomous driving. 【0030】 Note that in Figure 8, the snow removal plate 810, rear wheel bumper 815, and snow removal blade 840 are shown above the frame that constitutes the snow melting machine 800 for illustrative purposes, but in actual implementation of the present invention, they may be installed below the frame. 【0031】 As embodiments of the present invention have been described above, various alternatives, modifications, or variations are possible for those skilled in the art based on the above description, and the present invention encompasses the aforementioned various alternatives, modifications, or variations without departing from its spirit.
