BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pitching machine capable of realizing various types of pitch and pitch by controlling the rotational speed of a rotating wheel,

The four rotating wheels 130, 140, 150, and 160 are spaced apart from each other to form an X-like shape to form an inner hole 110 into which the inner hole 110 is inserted, (100); A supporting part 200 for supporting the pitching part 100 and adjusting a firing angle of the sphere; A controller 300 for controlling the rotational speed of each of the four rotating wheels 130, 140, 150, and 160 to determine a rotational speed and a rotational direction of the sphere to be fired; And a pitching machine capable of realizing a variety of pitches and pitches.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in FIGS. 1 to 5, a pitching machine capable of realizing various kinds of pitches and pitches according to the present invention includes four rotating wheels 130, 140, 150 and 160 arranged in an X- And a pitching unit (100) for forming an inner hole (110) into which the ball is inserted and emitting a ball inserted into the inner hole (110).

The pitching unit 100 is a device that fires a ball inserted in the backward direction toward a catcher or batter on the front side. The pitching unit 100 is a device for catching and / or hitting a pitcher and / And controls the rotation speed and the rotation direction.

At this time, it is preferable that the ball is basically used in a baseball game, but it is not limited thereto, and other types of ball such as a ball used for softball may be used.

In other words, the fastball is one of the types in which the orbital of the ball is relatively straight and the velocity is formed faster than the ball. The fastball is a four-seam fastball or a fastball two-seam fastball, and the like. The ball is a generic name of a variety of ball types in which the orbits of the ball are formed as curved lines as compared with the straight ball, and the velocity is slower than that of the straight ball. A slide ball, a splitter, a changeup, a fork ball, a screw ball, and a knuckle ball.

The inner hole 110 is a space in which the sphere is temporarily inserted for firing, and the volume of the space may be formed differently according to the interval between the four rotating wheels 130, 140, 150 and 160, In the case where the volume of the perforation 110 and the size of the sphere are formed differently, the sphere may not enter the inner perforation 110 or the traveling direction of the sphere may be out of the predicted range, The pitching machine capable of realizing various kinds of pitches and pitches according to the present invention is configured to adjust the distance between the four rotating wheels 130, 140, 150, and 160 so as to adjust the size of the inner hole 110 to fit the size of the sphere .

Therefore, it is characterized in that it comprises a circular or polygonal housing 120 in which a hollow is formed inside and a pair of supporting bars 121 are protruded downward, and one end of the housing 120 And a plurality of arms (170) coupled at one end to one of the four rotating wheels (130, 140, 150, 160) to support the rotating wheel. The pitching machine capable of realizing various kinds of pitches and pitches according to the present invention is characterized in that the four rotating wheels 130, 140, 150 and 160 can be arranged in an X-shape inside the hollow body by the plurality of arms 170, The distance between the rotating wheels can be adjusted by adjusting the depth of each of the plurality of arms 170 passing through the rotating shaft.

However, the method of adjusting the distance between the four rotating wheels 130, 140, 150, and 160 is not necessarily limited to the above example, and various other methods may be used.

As shown in FIG. 2, the four rotating wheels 130, 140, 150, and 160 may include a first rotating wheel (not shown) disposed obliquely downward in the left- A second rotating wheel 140 sloping downward to the right with respect to the inner hole 110 in the hollow, and a second rotating wheel 140 disposed on the inner side of the hollow, And a fourth rotating wheel 160 disposed at an upper right side of the hollow space with respect to the inner hollow 110. The first rotating wheel 150 may be divided into a first rotating wheel 150, The driving motor 180 is rotated by driving one of the plurality of driving motors 180 connected to the center of each of the first to fourth rotating wheels 130, 140, 150 and 160.

The plurality of driving motors 180 may include a first driving motor for rotating the first rotating wheel 130, a second driving motor for rotating the second rotating wheel 140, And a fourth driving motor for rotating the fourth rotating wheel 160. The four driving wheels 130, 140, 150 and 160 and the four driving motors 180 Each matching on a one-to-one basis.

Specifically, the first rotating wheel 130 and the second rotating wheel 140 provide rotational force to the sphere so that they can be fired forward, but the height of the sphere reaching the catcher and / or the batter side is lower than the firing point The third rotating wheel 150 and the fourth rotating wheel 160 can be rotated so that they can be fired forward by providing rotational force to the spheres, but the catcher and / or the ball reaching the batter side Make the height higher than the launch point.

When the first to fourth rotating wheels 160 rotate at the same speed, the emitted spheres form a straight line. However, since the rotational speeds of the first rotating wheel 130 and the second rotating wheel 140 are The third wheel 150 and the fourth wheel 160 rotate in a direction opposite to the rotation direction of the third wheel 150 and the fourth wheel 160, When the rotational speed of the first rotating wheel 130 is higher than the rotational speed of the first rotating wheel 130 and the second rotating wheel 140,

The first to fourth rotating wheels 130, 140, 150, and 160 may be formed to have different rotation speeds than the first to fourth rotating wheels 130, 140, 150 and 160 to provide a curveball, a slide ball, a splitter, a changeup, a forkball, So that a catcher catching the ball or a batting batter can be trained against a variety of ball types.

Particularly, the rotation speed of the third rotating wheel 150 and the fourth rotating wheel 160 is made higher than the rotating speed of the first rotating wheel 130 and the second rotating wheel 140, The speed of at least one of the first rotating wheel 130 to the fourth rotating wheel 160 is differently set so that the sphere forms a rising trajectory, The configuration is such that it is impossible to implement the conventional pitching machine in which two rotating wheels are arranged in a straight line or three rotating wheels are arranged in a Y-shape. With this configuration, the catcher and / You can get the same training effect as playing against a throwing pitcher.

That is, the conventional pitching machine can not implement a rising trajectory of the launched ball so that only a training such as a catcher or / and a batter can deal with a pitcher of an overhand hand type becomes possible, but using the pitching machine of the present invention, As a result, both of the upshift and downshift implementations of the sphere can be realized, so that the pitch and pitch of the type arms of the side arms or the underhand hands can be realized as well as the overhand hands, and this configuration is applicable to the side arms or the underhand type It is especially effective for the general public or amateur players who have little chance to get to know.
