Description

Pitching Machine for Batter Training

The present invention relates to the improvement of the baseball batting practice, and more particularly, baseball batting practice can be hit by hitting the ball automatically throwing at least a bunch of machines, such as a pitcher throws the ball in a baseball game It's about hitting exercises.

Baseball is now a popular sport that is more widely known to the public than in the past. In order to enjoy such a baseball game, batting practice should be accompanied by the characteristics of the sport, but in general, batting practice of baseball was a common practice of two-person batting practice in which one person throws the ball.

Since such a batting practice can always be organized in pairs of two people, there is a problem that can not be hitting alone.

As a throwing device that can throw a baseball by improving the problem that cannot be practiced alone, the thrower can throw the ball at a constant speed by using the belt device at the throwing part, so that the hitter can practice the batting but only a short throw is possible because of insufficient friction. It was only possible to pitch at a distance (usually a pitcher's pitch in a baseball game), so he couldn't get a sense of hitting.

In consideration of this point, a pitching machine capable of cultivating a batting sensation while satisfying a pitching distance has been introduced by the Utility Model Registration Application No. 2000-8649 of the applicant.

The throwing machine is provided with a pleats for improving frictional force on a pair of rotating drum surface to throw a baseball ball at a predetermined distance with the frictional force of the pleats between the drums, so that the batter hits the ball, so that the batting practice can be performed alone. It is possible to throw a ball at a constant speed by adjusting the interval of the rotating drum according to the wear condition of the ball. However, because the ball to be thrown is rubbed between the drums, the ball is damaged and the service life is not only shortened. Also, the new ball is periodically purchased and replaced with the old ball to maintain the correct pitching power. The expenditures associated with the purchase resulted in uneconomical use. In addition, since the friction coefficient of the rotating drum is always uniformly adjusted, the frictional state of the ball to be thrown is not uniform or one-sided friction, which leads to an irregular pitching state and thus an unstable blow.

In this regard, the present applicant has proposed a throwing device that can be thrown by an arm driving method instead of a friction method through Utility Model Registration Application No. 2001-8764. This thrower prevents the friction of the ball when it is thrown, prolonging the life of the ball, and throwing it at a constant speed regardless of the wear condition or size of the ball. Even if the ball is easily controlled, the ball can be freely pitched to distribute the ball to the hitter, thereby cultivating the sense of hitting and at the same time making economical use of the ball.

However, because the throwing device is a vertical movement of the throwing arm, the braking force by the braking means after the throwing is insufficient, the mechanical load is increased, so that the throwing arm can not be used due to damage or abnormality of the mechanism, and the throwing arm with the orthogonal movement force is not snapped Because the ball is thrown because the ball is thrown up from the pitching point or pitched to the desired distance is not thrown in the middle, there is a problem that can not be hitting practice.

In addition, in the hitting exerciser such as the Utility Model Registration Application No. 2001-24236 of the applicant of the present application, the rotating plate rotated by the motor shaft and the drive shaft connected to the belt and the pulley so that the pitcher throws the same pitch, and accommodates the rotating plate It includes a throwing guide passage, a supply pipe for periodically supplying the ball to the throwing guide cylinder, and a discharge pipe for throwing the ball periodically. Therefore, the ball injected into the throwing guide tube is thrown by the rotary plate to be thrown through the discharge pipe, but the throwing time becomes longer because the ball supplied through the supply pipe passes through the first and second accommodation chambers, and at the same time the first, 2 There is an uneconomical problem that is produced by the complex structure of the accommodation room, and also because the friction coefficient of the ball caused by the ball stoke of the throwing guide tube through which the ball is guided is large, the transportation of the ball is not smooth and the structural problem that hinders the pitching have.

The present invention has been devised to solve the conventional problems as described above, the object of the present invention is to simplify the internal structure of the throwing guide cylinder while reducing the friction coefficient of the ball to be guided ball is guided to a quick and good state By hitting the ball thrown from the pitcher during baseball games, the player can throw a batting practice, while maintaining a stable and continuous pitch without mechanical friction or load disturbance. It is to provide a baseball batting practice that can improve more effectively and achieve economical production with a simple structure.

Baseball batting practice of the present invention for achieving the above object is provided with a drive shaft connected to the motor shaft and the belt and the pulley, the pitch is formed by forming a supply pipe and a discharge pipe, respectively, in the throwing guide tube with a rotating plate attached to one end of the drive shaft In the baseball hitting exerciser made of, a attracting port attached to a predetermined position of the edge of the rotating plate to attract the ball introduced into the supply pipe, and disposed on the inside and outside of the area in which the attracting hole is rotated and installed along the curved surface of the throwing guide cylinder Including a guideway.

According to another embodiment of the present invention, the inlet is detachably attached to the rotating plate and is characterized in that the hemispherical groove is formed on the front surface protruding from the rotating plate.

According to another embodiment of the present invention, the ball induction bar is characterized in that the support bar is disposed on both sides, the support bar is bound by the pin shaft and at least one bearing is disposed.
