First, the solenoid valve (11) is excited to be in an open state, and compressed air is jetted from the compressed air supply pipe (18) via the air supply pipe (12). Then, due to the effect of the viscosity and the pressure difference of the air jetted from the tip of the compressed air supply pipe (18), the adhesive particles (10) in the storage chamber (14) pass through the powder supply pipe (17). Then it is injected with compressed air. In this case, the compressed air guided by the compressed air supply pipe (18) is the powder supply pipe (17).
Since the particles are sprayed from the surroundings of the vehicle, the adhesive particles (10) do not scatter like the spray particles (10a) shown in FIG. 1 due to the air curtain effect of the compressed air, so that the wheel (1) and the rail ( It is supplied between 2). This injection speed is, for example, the distance between the powder supply pipe (17) and the compressed air supply pipe (18).
When the compressed air pressure is 0.5 kg to 1.5 mm and the compressed air pressure is 5 kg / cm 2 , the pressure is 200 to 300 m / sec. When stopping the injection of the tackifying particles (10), the supply of compressed air to the compressed air supply pipe (18) may be stopped.

It is data showing how the difference l between the tip of the powder supply pipe (17) and the tip of the compressed air supply pipe (18) affects the injection amount (cc / sec) and the arrival efficiency. The arrival efficiency is the ratio of the amount of the tackifying particles that reach the target with a diameter of 50 mm at a position 250 mm away from the tip of the compressed air supply pipe (18) and the total injection amount injected from the powder supply pipe (17). is there. From the point of arrival efficiency, the difference in the tip of the injection pipe is 9 mm to 22.5 mm. That is,
When the inner diameter of the powder supply pipe (17) is d (mm), the tip difference l of the supply pipe has a relationship of 1 = (3 to 7.5) × d (mm).

In this figure, for example, when the inner diameter of the powder supply pipe (17) is 3 mm, the total injection amount is 7.5 cc / sec.
Is. And, from Figure 3, the arrival efficiency is about 50%, so if the distance between the wheel (1) and the rail (2) is 250 mm, about 3.8cc / sec will be about 3.8cc / sec between the wheel (1) and the rail (2). Reach in between.
