摘要

(57) [Abstract] To provide a Objective and apparatus for a new shot or grit or the like shot machine (projection grains) is automatically replenished once and apparatus for automatically recovering replenish projected particle used. [Configuration] replenishing device 30, the projection particle D shot machine 10 comes decreased, ammeter 3 which operates in accordance with the load current of the motor 15 for rotating the rotor 16 of the shot machine 10 1 needle 35 actuates the switch 36, opening the valve 33, and supplies a new projection particles D1 in the projected grain tank 34 to the shot machine 10 by a compressed air K. Needle 35 can swing in accordance with the supply of the projection grains, and to some extent provided, to close the valve 33 actuates the switch 37, stopping the supply.
