<p>The present invention relates to an automatic baseball training device. The automatic baseball training device comprises: a fixed chute extending in a longitudinal direction; a ball transferring device for transferring a ball inside the fixed chute; a vacuum pump for generating a vacuum force; one or more ball loading actuators being operated by the vacuum pump; a ball supporting part being raised and lowered by the ball loading actuator and generating negative pressure via the vacuum pump; and an operating chute for mounting, at the upper end of the ball supporting part, a ball that has passed the fixed chute. The automatic baseball training device according to the present invention has excellent training efficiency because balls are forcibly supplied without interruption. Balls can be supplied stably because the balls are mounted while attached using the vacuum pump capable of adsorption and exhaustion and the balls do not separate from a tee for supporting the balls even if the tee rises and stops abruptly. The present invention enables hitting exercise with various courses by placing a ball at any position inside a strike zone using a plurality of tees. Also a hitter can swing without a burden because the tees are made of synthetic resin or rubber and are erected vertically again after being hit by a bat. And the tees are easy to carry because the tees are disassembled into parts.</p> |
