Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a surface drying vehicle that dries a wet surface such as a ground surface of a core material for fill dam construction, a ground surface such as a ground, a baseball field, a soccer field, a golf field, and a construction site, and a construction surface such as a concrete floor. .
[0002]
[Prior art]
Conventionally, in the core dam construction work of fill dams, the core material erection surface is dried by natural drying by the sun, and when it falls within the specified moisture content range, the surface soil is further separated, and the next layer I was sweeping out. It usually took about 1 to 3 days from the time of fine weather until the water content was high enough to sweep out.
[0003]
As a method other than the sweeping, for example, the wetness of the surface is sucked out manually by using a direct swunge or the like.
[0004]
Further, the water accumulated in the ridges of the roller on the surface of the core material is squeezed out or drained by providing a water channel in the filter layer.
[0005]
In addition to the core material raised surface, natural drying is the main drying means even on wet surfaces such as ground, baseball fields, soccer fields, golf courses, grounds such as grounds, road surfaces, concrete construction surfaces, etc. there were.
[0006]
[Problems to be solved by the invention]
In the conventional surface drying method, it is necessary to wait for the ground surface to dry due to clear weather, and the method of removing with a sponge or the like is burdensome and time consuming, and when construction is urgent, etc. This will lead to work delays.
[0007]
In addition, the water collected in the ridge on the surface of the core material must be drained by connecting a water channel to the filter layer. The work could not be done, and the draining work could not proceed even in a hurry.
[0008]
If the surface is other than the core surface, for example, in a baseball stadium, a soccer field, an athletic ground, etc., from the management aspect, the surface water should be removed as soon as possible after the rain so as not to hinder the game. Technology is required.
[0009]
An object of the present invention is to enable drying of a wet surface such as a ground surface in a short time.
[0010]
[Means for Solving the Problems]
The present invention is a surface drying vehicle for drying a wet surface such as a wet ground surface, a carriage that moves the surface, a hot air blowing device that is provided on the carriage and blows hot air to the wet surface, An exhaust fan is provided on the carriage and exhausts steam from the surface to which hot air from the hot air blowing device is applied.
[0011]
The exhaust fan is provided with an intake port directed toward a surface side to which hot air blown from the hot air blowing device is actually applied.
[0012]
An opening is provided at the bottom of the carriage toward the surface on which the carriage moves, and an exhaust fan with an intake port directed toward the opening is provided above the opening. The air outlet of the hot air blowing device is provided on the peripheral edge side of the opening toward the surface side below the opening.
[0013]
When the carriage of the surface drying car having the above configuration is slowly moved on a wet surface such as a ground surface, hot air is blown toward the road surface from a hot air blowing device provided on the carriage. The water that has previously wetted the ground surface by the blown hot air is forcibly evaporated as water vapor. The water vapor is sucked by an exhaust fan provided on the carriage, and the surface is dried.
[0014]
When the hot air blowing device and the exhaust fan are provided on the cart, the hot air blowing device may be provided on the front side along the traveling direction of the cart, and the exhaust fan may be provided on the rear side of the hot air blowing device, or more drying efficiency. As a good configuration, the intake port of the exhaust fan may be located above the blowing target area of the hot air blowing device.
[0015]
In particular, if an exhaust fan is provided so that steam generated from the surface to which hot air is actually applied from the hot air blowing device can be quickly exhausted, surface drying can be performed in a shorter time.
[0016]
That is, with the above configuration, the water vapor suction operation by the exhaust fan and the hot air blowing operation by the hot air blowing device can be performed in parallel on the same surface area, compared to a configuration in which both operations are performed with a time difference. Since the steam is sucked upward immediately after the hot air is blown, the steam easily rises correspondingly, and the drying efficiency can be further improved.
[0017]
As such a configuration, for example, an opening is provided at the bottom of the carriage, an intake port of the exhaust fan is provided toward the opening, and the outlet of the hot air blowing device is wetted on the periphery of the opening. If it is provided so that hot air can be blown on the surface side, water vapor generated by the hot air being blown can be quickly exhausted to efficiently dry the surface.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0019]
As shown in the perspective view of FIG. 1, the surface drying vehicle 10 is configured by mounting a hot air blowing device 30 and an exhaust fan 40 on a carriage 20. The carriage 20 is provided with wheels 22 at the four corners of the bottom portion 21 of the vehicle body formed in a substantially box shape, and can move on a surface such as a wet ground surface.
[0020]
As shown in FIGS. 1 and 2, a circular opening 23 is provided in the center of the bottom at a position between the front and rear wheels 22 of the flat bottom 21. The opening 23 is opened toward the wet surface on which the surface drying wheel 10 moves.
[0021]
In this embodiment, the opening 23 will be described as having a circular shape. However, the opening 23 may be shaped so that hot air is blown from the opening toward the surface, and the steam generated by the hot air can be sucked and exhausted by the exhaust fan 40. For example, you may comprise in various shapes, such as a square opening part.
[0022]
In the opening 23 opened in the bottom 21 in the above-described manner, as shown in FIG. 3, the peripheral edge 23a is formed in a taper shape, and the taper-shaped peripheral edge 23a is formed on the rear side of the blowout side of the hot air blowing device 30. The side is installed.
[0023]
As shown in FIGS. 3 and 4, in the hot air blowing device 30, the duct 31 a emitted from both sides of the hot air generator 31 such as a jet heater is gradually lowered toward the lower side (see FIG. 2B). ), Both the ducts 31a have a shape that communicates with the air outlet 23 formed in a ring shape at the center.
[0024]
The duct 31a lowered from both sides of the hot air blowing device 31 in the above manner is communicated with the ring-shaped air outlet 32 provided in the center on the bottom 21 side, and the back surface portion of the air outlet 32 formed in this ring shape is shown in FIG. As shown in FIG. 3, it is fitted along the peripheral edge 23a of the opening 23 and fixedly attached.
[0025]
The blower outlet 32 is configured such that hot air is blown obliquely downward toward a wet surface such as a ground surface viewed through the opening 23 as indicated by an arrow in FIG. 3. The hot air blowing range from the blower outlet 32 is indicated by a broken line in FIG.
[0026]
In this manner, hot air is blown out from the outlet 32 whose blowing direction is set toward the inner side of the opening 23 toward the peripheral edge 23a of the opening 23, and hot air is concentrated on the wet surface from the surroundings. Then, a large amount of heat is supplied to the wet surface in a short time, and the water that has wetted the surface is forced to evaporate upward in a short time.
[0027]
As shown in FIG. 1, the hot air generator 31 constituting the hot air blowing device 30 is installed on the top plate 24 of the vehicle body, and the duct 31a penetrates the top plate 24 downward from both sides of the hot air generator 31, It communicates with the air outlet 32 on the bottom 21 side.
[0028]
Moreover, the hot air generator 31 is provided in the position biased to the side from the upper position of the blower outlet 32 formed in the ring shape, as shown to Fig.2 (a). The space above the air outlet 32 is opened for the exhaust fan 40 as shown in FIG.
[0029]
The exhaust fan 40 provided on the upper side of the air outlet 32 is formed in a substantially conical cylinder shape, and the bottom wide-mouth side of the conical cylinder body 41 has a ring-shaped air outlet as shown in FIGS. 32 is provided so as to cover the opening surface of the opening 23 provided on the peripheral edge 23a.
[0030]
The narrow mouth side of the conical cylinder body 41 penetrates above the top plate 24 of the vehicle body, and the tip end side is formed as a cylindrical exhaust end 42. A multiblade fan 43 is provided in the cylinder of the exhaust end 42 so that the motor can rotate. The multi-blade fan 43 is configured to suck water vapor from below and exhaust it upward.
[0031]
In such a configuration, the exhaust fan 40 is configured as a conical cylindrical body 41 with a narrowed top, so that the top plate is longer than the configuration in which the exhaust fan 40 is configured to extend upward in a cylindrical shape according to the diameter of the opening 32. The exhaust port 42 and the hot air generator 31 can be juxtaposed on the top plate 24 by reducing the diameter portion that penetrates the 24 side. Accordingly, the width of the carriage 20 can be reduced.
[0032]
However, when such consideration is unnecessary, the exhaust fan 40 is configured by extending the top plate 24 as it is in accordance with the diameter of the opening 23 and penetrating the top plate 24 and providing a multiblade fan on the penetrating end side. You may make it. The point is that the water vapor generated on the wet surface can be guided upward and exhausted to the outside.
[0033]
A generator 50 is provided on one end side of the carriage 20, and a power supply for the hot air blowing device 30 and the exhaust fan 40 is secured. In addition, a pulling member 25 provided with a hole in which a hook or the like is hooked on a substantially flat member is provided at the end of the cart 20 so that the cart 20 can be pulled and moved by the driving vehicle. Yes.
[0034]
Further, a skirt 26 made of a material such as rubber is provided downward from the bottom 21 of the carriage 20 so that hot air blown from the air outlet 32 to the surface side such as a wet ground surface does not escape.
[0035]
The surface drying wheel 10 having the above-described configuration is used to dry a surface such as a wet ground surface as follows.
[0036]
A hook for pulling a driving vehicle (not shown) is hung on the pulling member 25 of the surface drying vehicle 10 and is pulled by the driving vehicle and conveyed to the work place. At the work place, when the surface drying vehicle 10 is towed, the operation of the hot air blowing device 30 and the exhaust fan 40 is started. In a state where both fans are operated, the surface drying vehicle 10 is slowly moved within the working range by the driving vehicle.
[0037]
As the surface drying vehicle 10 moves, hot air produced by the hot air blowing device 31 is blown out from the blowout port 32 to the surface portion viewed from the opening 23 provided in the bottom portion 21 of the carriage 20, as shown in FIGS. As shown, it will be sprayed.
[0038]
A large amount of hot air is blown on the surface viewed from the opening 23 in a short time, and the moisture that has wetted the surface until then becomes water vapor and is forced to evaporate upward. Since the upper portion of the opening 23 is covered with a conical cylinder 41 connected to the exhaust end 42 provided with the multiblade fan 43, the forcibly evaporated water vapor is discharged to the exhaust end guided by the conical cylinder 41. 42 side is exhausted to the outside air from there.
[0039]
In the surface drying vehicle 10 of the present embodiment, the carriage 20 is configured to be pulled by another driving vehicle, but may be configured in a self-propelled manner. Alternatively, a handle may be provided on the carriage 20 so that it can be moved while being pushed by human power.
[0040]
In the above description, as shown in FIGS. 1 and 2, the configuration in which the hot air generating device 30 and the exhaust fan 40 are provided side by side in the width direction of the top plate 24 of the carriage 20 is shown, but other arrangement methods may be used. .
[0041]
In the surface drying vehicle 10, the air outlet 32 and the exhaust fan 30 are provided on the same opening 23 side. However, as shown in FIG. 5, the openings 23, 23 ′ are front and rear at the bottom 21 of the same carriage 20. It is also conceivable that the hot air blowing device 30 is provided on the opening 23 side as described above, and the exhaust fan 40 is provided in the opening 23 ′.
[0042]
As the surface drying vehicle 10 moves, hot air is blown from the hot air blowing device 30, and then the exhaust fan 40 moves onto the surface on which the hot air is blown to exhaust the generated steam. Although the efficiency is somewhat lower than in the case of the above-described configuration in which the hot air blowing device 30 and the exhaust fan 40 are provided in the same opening 23 to perform surface drying, the configuration shown in FIG. 5 is also compared with the conventional manual drying operation. It is very efficient.
[0043]
【The invention's effect】
In the present invention, the surface can be dried while moving on a wet surface such as the ground surface.
[0044]
In the present invention, the drying process can be mechanized as compared with the conventional method of drying using a sponge or the like.
[0045]
In the present invention, the drying time can be shortened by mechanizing the drying process.
[0046]
In the present invention, hot air is blown and the generated steam can be exhausted and forcedly dried, so that the ground surface and the like can be dried without waiting for fine weather.
[0047]
In the present invention, since the blowing direction is formed so as to face the surface side from the peripheral edge of the opening, and the exhaust fan is provided above, the water vapor generated by hot air irradiation does not stagnate on the surface. Compared with the case where the hot air blowing device and the exhaust fan are installed at different positions and the hot air is applied to the exhaust fan after moving to the hot air irradiation position after a while. Water vapor generated by blowing is quickly exhausted without stagnation on the surface, and drying efficiency is improved.
