A pitching machine includes a stand unit, a direction adjusting device swivelably mounted on the stand unit, a base unit pivotally mounted on the direction adjusting device, two pitch adjusting devices mounted on the base unit, and an angle adjusting device pivotally mounted between the base unit and the direction adjusting device. The base unit includes a base frame, two side brackets, two screwed sockets, two rotation wheels, two drive motors, a guide track, and a push member. Thus, the inclined angle of each of the rotation wheels can be adjusted individually by each of the pitch adjusting devices so that the rotation wheels can be adapted to have different inclined angles. In addition, the angle adjusting device can move the base frame relative to the support arm to change the inclined angle of the base frame. |
