1 to 4 and 10, the snow removing apparatus 1 according to an embodiment of the present invention is the base 10, the first steam sprayer 20, the second steam sprayer 30, hot air sprayer ( 40, 50, a control unit 60, a removal unit 70, and a power generation unit G.

The snow removing apparatus 1 includes the first steam sprayer 20, the second steam sprayer 30, the hot air sprayers 40 and 50, the controller 60, the remover 70, and the power generator G, respectively. 10, the entire snow removal apparatus 1 can be easily transported only by the movement of the base 10.

Therefore, if it is mounted on the vehicle (V) and wants to use it in another device, it is only necessary to dismantle the base 10 from the vehicle (V) and then move it to another device. It has the advantage of being mixed.

In addition, if there is a space to mount the base 10 can be equipped with a snow removal device (1) in any device, including the vehicle (V) can be carried out snow removal work as a general vehicle without the need for a separate snow removal vehicle. have.

As such, the base 10 serves to modularize the snow removal apparatus 1 into one, and various electric components of the snow removal apparatus 1 may be embedded. The base 10 may be provided with a boarding unit (not shown) to allow an operator to operate the snow removal apparatus 1.

The first steam injector 20 is mounted to the front of the base 10 and injects steam toward the bottom surface. The first steam injector 20 includes a first steam generator 21, a first steam supply pipe 22, and a first steam discharger 23.

The first steam generator 21 is installed above the base 10. The first steam generator 21 generates steam and provides the generated steam to the first steam supply pipe 22 communicating with each other.

The first steam generator 21 may be rotatably installed in the horizontal direction with respect to the base 10. Therefore, since the injection range of steam through the first steam injector 20 can be expanded, the snow removing effect by the first steam injector 20 can be further improved. The rotation of the first steam generating unit 21 is made by an instruction of the controller 60.

The first steam supply pipe 22 communicates with the first steam generator 21 and extends toward the front of the first steam generator 21. The first steam supply pipe 22 serves as an intermediary for supplying the steam generated by the first steam generator 21 to the first steam discharger 23.

The first steam supply pipe 22 includes a pair of supply passages 22a and 22b extending forward from the first steam generator 21 and branching to both left and right sides. The distance between the pair of supply passages 22a and 22b is formed to be wider than the width of the driver's seat of the vehicle V, and each of the supply passages 22a and 22b is arranged in parallel with each other.

The first steam supply pipe 22 is rotatably mounted in the vertical direction with respect to the first steam generating part 21. Therefore, when the first steam injector 20 is operated, the first steam supply pipe 22 is moved downward toward the bottom surface to more closely arrange the first steam discharge part 23 and the bottom surface to discharge the first steam. The steam remaining in the section 23 can remove snow remaining on the bottom surface in a shorter time.

On the contrary, when the operation of the first steam injector 20 is completed, the first steam supply pipe 22 may be moved upward to prevent the first steam discharge part 23 from being damaged by an obstacle present on the bottom surface. . At this time, the rotation of the first steam supply pipe 22 is made by the instruction of the control unit 60.

The first steam outlets 23 are respectively coupled to ends of the supply passages 22a and 22b. Therefore, the first steam discharge part 23 is disposed in the left and right direction perpendicular to the supply passages 22a and 22b. Thus, when the snow removing apparatus 1 is mounted on the vehicle V, the first steam discharge unit 23 may be disposed perpendicular to the traveling direction of the vehicle V to expand the injection range.

Since the first steam discharge unit 23 communicates with the supply passages 22a and 22b, the first steam discharge unit 23 receives the steam generated by the first steam generator 21 through the supply passages 22a and 22b. At this time, the first steam discharge unit 23 may inject steam in a direction perpendicular to the bottom surface (see FIG. 8). In the present embodiment, the first steam discharge portion 23 is formed in a long duct shape.

Referring to FIG. 7, the first steam discharge unit 23 has a plurality of injection holes 23a arranged at a predetermined interval at a lower portion thereof. Since the steam is injected to the bottom surface through the injection hole 23a, the steam is uniformly sprayed along the longitudinal direction of the first steam discharge unit 23.

1 to 4 and 10, the steam of the first steam injector 20 is evaporated from the water to a gaseous state, the steam generated in the first steam injector 20 to the snow accumulated on the bottom surface When spraying at high pressure, pressure is added to the heat of the steam, which can easily destroy the accumulated snow tissue.

On the other hand, the first steam injector 20 may spray water instead of steam. Water can apply more pressure per unit area than steam, so it has the advantage of distinguishing steam from destroying snow tissue if the temperature is not too low, ie if the risk of freezing is low.

The second steam injector 30 is mounted to the base 10 so as to be disposed behind the first steam injector 20 and injects steam toward the bottom surface. The second steam injector 30 includes a second steam generator 31, a second steam supply pipe 32, and a second steam discharger 33.

The gap between the pair of supply passages 32a and 32b is formed to be wider than the width of the trailing edge of the vehicle V, and each of the supply passages 32a and 32b is arranged in parallel with each other.

The second steam supply pipe 32 is rotatably mounted in the vertical direction with respect to the second steam generator 31. Therefore, when the second steam injector 30 is operated, the second steam supply pipe 32 is moved downward toward the bottom to more closely arrange the second steam discharge part 33 and the bottom to discharge the second steam. The steam remaining in the part 33 can remove snow remaining on the bottom surface in a shorter time.

On the contrary, when the operation of the second steam injector 30 is completed, by moving the second steam supply pipe 32 upward, the second steam discharge unit 33 may be prevented from being damaged by an obstacle existing on the bottom surface. . At this time, the rotation of the second steam supply pipe 32 is made by the instruction of the control unit 60.

The second steam discharge portion 33 is coupled to the ends of the supply passages 32a and 32b, respectively. Therefore, the second steam discharge part 33 is disposed in the left and right direction perpendicular to the supply passages 32a and 32b. Thus, when the snow removal apparatus 1 is mounted on the vehicle V, the second steam discharge unit 33 may be disposed perpendicular to the traveling direction of the vehicle V to expand the injection range.

Since the second steam discharge part 33 communicates with the supply flow paths 32a and 32b, the second steam discharge part 33 receives the steam generated by the second steam generation part 31 through the supply flow paths 32a and 32b. In this case, the second steam discharge unit 33 may inject steam in a direction perpendicular to the bottom surface (see FIG. 8). In the present embodiment, the second steam discharge part 33 is formed in a long duct shape.

Referring to FIG. 6, the second steam discharge part 33 is provided with a plurality of injection holes 33a arranged at predetermined intervals at a lower portion thereof. Since the steam is injected to the bottom surface through the injection hole 33a, the steam is uniformly sprayed along the length direction of the second steam discharge part 33.

1 to 4 and 10, the steam of the second steam injector 30 is evaporated from the water to a gaseous state, the steam generated in the second steam injector 30 to the snow accumulated on the bottom surface When spraying at high pressure, pressure is added to the heat of the steam, which can easily destroy the accumulated snow tissue.

On the other hand, the second steam injector 30 may spray water instead of steam. Water can apply more pressure per unit area than steam, so it has the advantage of distinguishing steam from destroying snow tissue if the temperature is not too low, ie if the risk of freezing is low.

The hot air injectors 40 and 50 are disposed behind the second steam injector 30 and spray hot air toward the bottom surface. The hot air injectors 40 and 50 include supports 41 and 51, connecting tables 42 and 52, and hot air spray units 43 and 53.

Supports 41 and 51 are mounted to the base 10 to be disposed behind the second steam generator 31. One end portion of the connecting table 42 and 52 is rotatably installed in the supporting members 41 and 51 in the up-down direction or the left-right direction, and the other end is coupled to the hot air spraying parts 43 and 53.

And it can be arranged, it can further expand the range in which the hot air is injected from side to side.

8 to 10, the hot air spray units 43 and 53 are rotatably coupled to the other ends of the connecting tables 42 and 52 in the front-rear direction, and spray hot air toward the bottom surface. The hot air spray units 43 and 53 include the housings 46 and 56, the heating units 47 and 57, and the air blowing units 48 and 58.

The housings 46 and 56 are formed in a cylindrical shape with the lower end opening. The housings 46 and 56 are rotatably coupled to the other ends of the connecting tables 42 and 52 in the front-rear direction. The housings 46 and 56 are rotated by receiving an instruction from the control unit 60 and using one side of the connecting tables 42 and 52 as the rotation axis.

By the rotation of the housings 46 and 56, the hot air jetting parts 43 and 53 can extend the injection range of hot air in the front-back direction. The specific rotation direction and angle of the housings 46 and 56 are controlled by the controller 60.

The heating parts 47 and 57 are provided inside the housings 46 and 56, and generate hot air by heating a fluid flowing into the housings 46 and 56 from the outside. A plurality of long holes (not shown) are formed at upper ends of the housings 46 and 56 so that fluid can easily flow into the housings 46 and 56.

In the present embodiment, the heating parts 47 and 57 are illustrated as hot wires, but the heating parts 47 and 57 need not be limited thereto as long as the heating parts 47 and 57 are capable of heating a fluid existing in the housings 46 and 56.

Blowing parts 48 and 58 are provided inside the housings 46 and 56, and blow hot air generated by the heating parts 47 and 57 to the lower end side of the housings 46 and 56. Although the blowers 48 and 58 are shown as fans in the present embodiment, if the hot air can be sprayed to the lower end side of the housings 46 and 56, it can be replaced with another configuration.

The blowers 48 and 58 allow the inflow of fluid into the housings 46 and 56 and the discharge of the heated fluid into the lower ends of the housings 46 and 56.

In this embodiment the fluid is air. The air is not only easily heated by the heating parts 47 and 57 but also has an advantage of applying less pressure to the object relative to steam. That is, the fluid is sprayed toward the object in the direction of gravity from the upper side due to the characteristics of the hot-air jet parts 43 and 53, the use of air in the case of the object that can not withstand the large pressure, such as grass helps to prevent the damage of the object.

The hot air injectors 40 and 50 are divided into a central hot air injector 40 and an outer hot air injector 50 according to the position disposed on the base 10. In the present embodiment, the central hot air injector 40 is illustrated to extend further to the rear than the outer hot air injector 50, but the reverse may be reversed.
