AN IRON BALL VARIABLE HITTING APPARATUS OF RECREATION FACILITIES PROVIDE WITH SOLENOID

摘要

It can be changed output type gold bead device for the one of hammering to be arranged to control solenoidal metal bead batting intensity by the control pulse length of driving voltage. A metal pearl device is used for the solenoid part hammered include: for hitting metal bead; One driving voltage generates unit, is used to provide solenoidal applied voltage; For controlling a solenoidal switching controller. Solenoid part (100) includes a spool (101), a magnet exciting coil (102), a plunger (103) and an extension spring (104). The plunger arm (105) of alkali metal and high resiliency impact spring head (106) is mounted in plunger, in order to collide metal bead.
