2. Description of the Related Art The floor coating agent coating machine has been designed so that the coating agent can be applied to the floor surface and the coating agent can be dried at once by simply moving the floor body. It is a thing. In this type of applicator, the drying conventionally provided by a blower
The air is blown so that the air can smoothly flow out from the floor of the destination.
Install the ventilation port of the device at a place relatively high above the floor.
Has been. In addition, the vent has a relatively short front and rear length.
It is configured to be relatively remote from the coating device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 3, one cater-type idle front wheel 1 is provided, and a pair of left and right rear wheels 2 and 2 are drivable by an electric motor M1 for traveling, and steering is performed. At the front of the traveling machine body 4 provided with the handle 3, a supply device 5 for supplying a coating agent to the floor surface by a supply nozzle 5a, a coating device 6 for coating the floor surface with a coating tool 6a, and a coating agent tank 7 are attached. At the same time, a blower 8 for supplying dry air to the floor surface by a blower fan 8a is attached to a location located behind the coating device 6 of the traveling machine body 4, and the blower 8, the coating agent tank 7, the traveling motor M1, etc. A cover 9 covering the above is attached to the upper part of the traveling machine body 4 to form a walking type self-propelled floor coating agent coating machine. This coating agent applicator stores a thermoplastic resin-based coating agent solution in a coating agent tank 7 and makes it self-propelled on a floor made of stone, wood, concrete or a chemical flooring material,
The process of supplying and applying the coating agent to the floor surface and the process of drying and solidifying the applied coating agent can be automatically performed, and the details are configured as follows.

That is, the supply device 5 is composed of one supply nozzle 5a, an electric liquid feed pump 5b, a nozzle transfer endless belt 5c, an electric nozzle transfer motor M2, etc., and the electric liquid supply pump 5b is used for running the machine body. It is driven along with it, and supplies the coating agent solution from the coating agent tank 7 to the hose 1
It is configured to be taken out via 0 and supplied to the supply nozzle 5a. The supply nozzle 5a is configured to drop the coating agent from the liquid supply hose 10 onto the floor surface by the supply pressure of the electric liquid supply pump 5b, and is attached to the nozzle transfer endless belt 5c. Nozzle transfer motor M2
Is automatically and normally driven in accordance with traveling of the machine body, and drives the nozzle transfer endless belt 5c to switch between the forward rotation direction and the reverse rotation direction via the belt support shaft 11, thereby driving the supply nozzle 5a. It is configured to reciprocate in the lateral direction of the machine body. That is, the supply nozzle 5a drops the coating agent solution from the liquid supply pump 5b on the floor surface, and moves zigzag above the floor surface for the purpose of traveling the machine body and the reciprocating transfer by the nozzle transfer motor M2. As the process progresses, the coating agent is supplied to the floor surface using the width determined by the nozzle movement stroke as the supply processing width. The applicator 6 comprises the applicator 6a, an applicator drive mechanism 6b and an electric application motor M3, and the applicator drive mechanism 6b is driven by the application motor M3 as the machine body travels to apply the applicator 6a to the floor surface. Since the applicator 6a is configured to vibrate vertically so as to act, and the applicator 6a is positioned on the rear side of the supply nozzle 5a, the coating agent from the supply device 5 is applied by the applicator 6a as the machine travels. The coating process is applied to the floor surface. The blower 8 is
The blower fan 8a, the wind tunnel body 8b, and the electric blower motor M4 are provided, and the blower fan 8a is rotatably driven by the blower motor M4 as the machine travels to cover an intake port 12 formed in the upper portion of the machine body cover 9. The outside air is sucked into the wind tunnel body 8b and is discharged downward from the ventilation port 13 formed by the lower end side of the wind tunnel body 8b, and the ventilation port 13 is located at the rear side of the applicator 6a. By doing so, the room temperature air is supplied as the coating agent drying air to the floor surface after the application treatment by the application tool 6a as the machine body travels.

When the machine is moved at 6 to 15 m / min, the time for the dry air to act on the coating agent after application is appropriate so that a good finished state can be obtained, so that the blower opening 13 is in the machine longitudinal direction. The relationship between the length Lcm and the traveling speed Vcm / min of the machine is L / V = 60/700 to 60
It is set to / 1500. This was set based on the experimental results under the experimental conditions shown in Table 2 below, using the floor coating liquid having the physical properties shown in Table 1 below.

[0010]

[Table 1]

[0011]

[Table 2]

The blower opening 13 is close to the applicator 6a in the machine front-rear direction so that the front-rear length of the entire machine can be kept relatively short in comparison with the length L of the air blower 13 in the machine front-rear direction. It is arranged to Nevertheless, the sheet metal shield 14 against the drying air of the coating agent from the air outlet 13 is configured and provided so as to be supported by the wind tunnel body 8b, so that coating failure or drying failure due to the drying air of the coating agent occurs. Consideration is made so that it is difficult to do. That is, as shown in FIGS. 1 and 2, the shield 14 includes a front shield plate portion 14a located between the blower opening 13 and the applicator 6a so as to partition the blower opening 13 and the applicator 6a, and both lateral sides of the blower opening 13. A pair of horizontal shielding plate portions 14b, 14b for individually covering the vicinity of each side are provided, and the dry air from the blower opening 13 is applied by the partitioning action and the covering action of the front shielding plate portion 14a and the horizontal shielding plate portion 14b.
It is configured so as to suppress the flow into a. In other words, it is intended to prevent the coating agent during the coating process from contacting dry air and solidifying. Further, since the shield 14 is open without covering the rear side of the air blower 13 on the airframe, the dry air after being supplied to the floor surface from the air blower 13 to dry the coating agent is on the rear side of the airframe. It is designed to allow easy flow. In other words, the drying air quickly passes over the floor surface to be dried so that high drying efficiency can be obtained.

[Other Embodiments] As the applicator of the applicator,
In addition to the vibration type applicator, various types such as a rotary type and a brush type having different operation types and applicator types may be adopted for implementation, and these are collectively referred to as an application processing unit 6a. . The present invention can also be applied to a non-self-propelled applicator in which the machine body is moved by the hand push of an operator.

It should be noted that although reference numerals are given in the claims for convenience of comparison with the drawings, the present invention is not limited to the structures of the accompanying drawings by the entry.
