This design has the disadvantages of: the spin ball cannot be generated, the actual training is that the spin ball is very necessary, the timely coping strategy and action of the training players on the spin ball are one of the basic purposes of the training, and different spin can bring different track effects of the ball. When the ball flies forward without rotating, the air on the upper, lower, left and left surfaces of the ball flows backward at the same speed. If the ball body rotates upwards, air on the upper part of the ball is driven to flow forwards and is abutted against the air flowing backwards, so that the air flow rate on the upper part of the ball is reduced, and the pressure is increased; the upward rotation of the ball drives the air at the lower part of the ball to flow backwards, and the air flow velocity at the lower part of the ball is increased and the pressure is reduced. Thus, the ball is pressed down quickly in flight due to the large upper pressure and the small lower pressure of the ball, and a falling parabola track is formed. The faster the rotation, the faster the descent speed. Similarly, the downward rotating ball flies upward and the side rotating ball inclines. The hit ball cannot rotate, which is very different from the actual serving effect, and thus cannot adapt to the high-quality training effect.

Detailed Description
The present invention will be described in further detail below by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not to be construed as limiting the present invention.
The multifunctional court training pitching machine has the following functions to achieve the perfect actual training effect.
(1) The ball 6 sent out by the pitching machine should rotate, and as a preferred design, the spinning direction can be adjusted; the spin direction should be capable of selecting the conventional spin mode such as spin up, spin down, spin left, spin right, etc., and as a preferred design, the spin speed can be adjusted, and there is no direct correlation between the selected speed and the ejection speed of the ejected ball 6, so that the ejected ball 6 can be in the state of low speed (ejection speed) high rotation (spin speed), high speed high rotation, low speed low rotation, low speed high rotation, etc.,
(2) the service robot can realize continuous service, and as a preferred design, the service action process of the service robot can prepare for the ball feeding 6 (the ball 6 enters the launching cavity 311), thereby improving the service efficiency.
(3) The serving speed of the serving machine should be adjustable, and the adjustment is preferably made by electronic control.
Preferably, the shooting angle of the service ball of the service robot can be adjusted, and as a preferred design, the shooting angle can be automatically controlled and adjusted through electric control,
in order to achieve the above design objective, the working process of the present invention comprises the following steps:

(2) in step S2, the two ends of the ball 6 located at the spin station are pressed by the rotating pressing rod 52 of the spin adjusting module 5, and then the pushing cylinder 42 moves backwards slightly to avoid contacting the outer wall of the ball 6, the rotating pressing rod 52 drives the ball 6 to spin,
(3) in step S3, the blocking of the ball striking rod 32 is released, the ball striking rod 32 moves forward rapidly by the power storage spring 321, the rotary pressing rod 52 moves outward in the radial direction with respect to the ball 6, the lower end of the rotary pressing rod 52 is separated from the surface of the ball 6, and the ball 6 with spin is rapidly hit by the ball striking rod 32.
In step S2, the direction of spin is adjusted by adjusting the rotation of the rotary presser bar 52 relative to the axis of the pusher cylinder 42.
Preferably, in step S2, after the lower end of the rotary press rod 52 is separated from the surface of the ball 6, at least two core rods 53 are pushed against the surface of the ball 6, and the end surface of the core rod 53 is made to be a hemispherical surface 6, so as to reduce the contact surface between the core rod 53 and the ball 6, so that the position deviation of the ball 6 is not too large at the moment of separation of the rotary press rod 52, and the applicant tests that if the core rod 53 is absent, the bounce range of the contact point of the ball striking rod 32 striking the ball 6 is large, which greatly affects the stability of the serve, and after the core rod 53 is used, the bounce and floating of the ball 6 are reduced at the moment of separation, the bounce range of the contact point of the ball striking rod 32 striking the ball 6 is small, which greatly improves the stability of the serve,
