FIG. 3 is a schematic diagram showing an example of a conventional ice and snow pressure-feeding device. As shown in FIG. 2, for example, the rotary feeder 3 used in the conventional ice-and-snow pressure-feeding device 1'is provided with ice-snow received from the receiving port 3b in a cylindrical rotatable main body 3c below the receiving port 3b. In addition, the semi-circular groove-shaped supply parts 3a, 3a, 3a, 3a are intermittently supplied so as to drop when the supply part 3a and the receiving port 3b are in communication with each other by the rotation of the rotating body 3c. Has been formed. Further, in the conventional ice and snow pumping device 1 ′, as shown in FIG. 3, for example, the air 10 sucked from the blower 2 and the ice and snow 6 from the rotary feeder 3 are pumped to the left side in the drawing, that is, to the ice jet device 4 side. For the blower 2
The air 10 supplied from the above is connected to one supply unit 3a of the rotary feeder 3 in a form of being supplied. Therefore, when the ice and snow 6 is pressure-fed, the blower 2 is driven to suck the outside air 10 into the intake pipe 27 through the air filter 9 to compress it, and then the blower 2 adiabatically compresses and raises the temperature. The air 10 is returned to a temperature before being sucked by a heat exchanger 5 such as an intercooler and supplied to the rotary feeder 3, and the ice 10 is mixed with the air 10 in the rotary feeder 3. Then, the ice and snow 6 supplied from the rotary feeder 3 into the pipe line 8 is crushed into small pieces by collision with the inner wall of the pipe line 8 during the pressure feeding, and is supplied to the ice blasting device 4 on the left side in the figure. , Ice and snow 6 fragmented from the ice-blowing device 4
Was sprayed on the slopes.

During mixing in the rotary feeder 3, the pressure of the air 10 fluctuates before and after the pipe 8 and the supply unit 3a communicate with each other and the ice and snow 6 supplied to the supply unit 3a is pressure-fed by the air 10. The load that compresses the air 10 by the blower 2 changes due to the pressure fluctuation that occurs when the ice snow 6 is pumped by the air 10, so that repeated stress acts on the impeller of the blower 2 and the life of the blade against fatigue damage is shortened. It is consumed and the output of a drive source such as an electric motor is also changed to change the number of revolutions, so that the rotating parts such as bearings are deteriorated quickly.
