Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Application Public Fund The present invention provides a device for firing balls, such as softball balls, by rotating the pitching rotors of two pitching boxes. This invention relates to a pitching machine that can simultaneously launch two balls to a player and pitch different types of balls to -1 batter.

Conventional technology There is no known pitching machine that can pitch two balls at the same time.

As shown in FIGS. 7 and 8, a conventional pitching machine has two pillars 12 and 13 erected in the front and back on the table 10,
It consists of a pitching box 16 that is rotatably supported by the support column 12.13 via a shaft 14.15, and a drive that rotates two external pitching rotors 25 at high speed within the pitching box 16 via a drive shaft. In a pitching machine to which the device is attached, the pitching rotor 25 provided outside is rotated in a different direction, and the ball is sandwiched between the rotors 25 and pitched, and the pitching box 16 is supported. The table 10 is pivoted by a rotation support 5 via a pipe 11 below the table 10 so that it rotates vertically around the center of the table 10 as a fulcrum, and the rotation support 5 rotates vertically below the fulcrum. The connection between the base 10 and the rotation support base 5 is such that the pipe 11, which is supported perpendicularly to the pitching direction below the base 10, is connected to the rotation support base 5 through a thrust bearing 4. Two types are known: one is a type with a shaft mounted on the top, and the other type is a type in which a screw 8 locked at the rear of the rotating support stand 5 is screwed into the stand 10 (Utility Model Application No. 63-71072). ).

Such a pitching machine has the advantage of being able to change the pitching direction from front to back, left and right, and also being able to pitch various types of balls by rotating the pitching box and changing the rotational speed of the pitching rotor.

Problems to be Solved by the Invention However, such conventional pitching machines can only pitch one ball at a time, and cannot pitch in different directions at the same time.

When attempting to pitch two balls at the same time, the only option is to use two pitching machines of the same type side by side to pitch, but this has the disadvantage of occupying too much space.

When pitching different types of balls to batters,
It is necessary to set the pitching direction, angle, etc. one by one, which has the disadvantage of taking time to set.

Therefore, in view of the drawbacks of the prior art, the present invention has the following features:
- The aim is to provide a device that can pitch different types of balls to a human batter.

Means for Solving the Problems The present invention provides a truck equipped with wheels, and horizontal bisected parts longitudinally relative to the traveling direction of the truck, one front part and the other rear part. a support stand having a bearing rotatably connected in a direction; a pitching table each pivotally connected to the bearing of the support stand so as to be swingable; and two pitching boxes rotatably supported by the support via a shaft. This object is achieved by a pitching machine configured such that the rotation of the support base is locked to the trolley.

Function: In the pitching machine of the present invention, two pitching boxes are mounted diagonally on a rectangular cart, and the pitching boxes can freely change the direction of pitching to the front, back, left, or right without colliding with each other.

Then, the direction of pitching is determined, and each support base is rotated horizontally on the trolley in accordance with the pitching direction.

Next, the swing angle of the pitching box is determined and fixed by adjusting the screw between the pitching table and the support base.

Furthermore, the pitching box, which is rotatably supported by the support via a shaft, is rotated to determine the type of pitch to be pitched, and the pitching is performed.

Since the pitching box is equipped with an independent drive device, by simultaneously sandwiching the ball between two types of pitching rotors, it is possible to shoot different types of balls in different directions at the same time.

It is also possible to alternately pitch two different types of pitches at different speeds in the same direction.
