Novel baseball simulated training device

The invention relates to a novel baseball simulated training device. The novel baseball simulated training device comprises a projector, a screen and 3D glasses, wherein the projector is used for projecting a 3D simulated scene; a user can wear the 3D glasses during training; an automatic ball machine and a control device are further arranged at the rear of the screen; the control device is used for controlling the ball serving speed, the ball serving angle and the ball serving time of the automatic ball machine to be matched with a ball serving situation in the 3D simulated scene; a hole is formed in the screen; and a cover plate which is used for covering the hole at ordinary times but actively or positively opens during launching of the baseball. After wearing the 3D glasses, a user seems like staying in a real competition terrain, the simulated scene has a pitcher, and because the ball is served really, a trainee has rear force feedback when hitting the ball, and can really sense optimal ball hitting, tra
