1. A ball detection device comprising:
a support rack including a fixing portion;
a target plate fixed in front of the support rack and spaced from the fixing portion, the target plate including nine marking zones formed on a front segment of the target plate, wherein a respective one marking zone has a passing orifice defined therein;
a sensing module including multiple ultrasonic sensors corresponding to the nine marking zones of the target plate, wherein a respective one ultrasonic sensor is received in the fixing portion and corresponds to the passing orifice of the respective one marking zone, such that when the respective one ultrasonic sensor emits ultrasounds to the respective one marking zone, the ultrasounds emit out of the target plate via the passing orifice, thus sensing a ball hitting position and a ball pitching speed by using the respective one ultrasonic sensor; and
a control unit electrically connected with the sensing module and configured to record and display the ball hitting position and the ball pitching speed.
