Abstract: A speed measuring device includes an adapter pad, two mounting boards, a guide plate, and two speed detection units. The adapter pad includes a base plate and a joint plate adapted to be assembled on a mounting rack of a ball pitching machine. Each mounting board is installed on one of two sides of the base plate and includes spaced first and second sections. The guide plate is assembled on the first sections of the mounting boards. A width between the moveable mounting boards relative to the base plate and longitudinal positions of the two mounting boards relative to the ball pitching machine are respectively adjustable. The speed detection units mounted on inner surfaces of the second sections of the mounting boards define a space through which a ball passes for detecting speed of the ball shot by the ball pitching machine.

Abstract: A ball pitching machine includes a tripod, a mounting base, two rotary wheel devices, and a ball holder. The mounting base includes an engaging member rotatably mounted to a pillar of the tripod and a mounting plate pivotably coupled to the engaging member. The rotary wheel devices are mounted on two sides of the mounting plate and each includes a rotary wheel. The ball holder is mounted to the mounting plate and located between the rotary wheel devices. The ball holder of the ball pitching machine is applicable to different-sized rugby balls or soccer balls and can be easily adjusted to any elevation angle. The ball pitching machine allows elevation angles of the mounting base to be adjusted, and also allows elevation angles of the rotary wheels to be adjusted.

Abstract: A rotary wheel for a ball pitching machine includes a wheel body and a resilient member engaged on an outer periphery of the wheel body. A shaft hole is provided in the wheel body for receiving a shaft of a motor of the ball pitching machine. The wheel body includes a spring portion arranged between the shaft hole and the outer periphery of the wheel body in a radial direction and including first and second bending portions both of which protrude from two sides of the wheel body respectively. When the rotary wheel is driven to turn by the motor, a frictional force of contact of the resilient member with a ball makes the ball shot outwardly, and the rotary wheel is not broken or damaged due to the spring portion compressed in the radial direction to absorb the impact energy.

Abstract: 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.

Abstract: A baseball and softball practicing apparatus includes a stand, a housing mounted on the stand, a ball throwing wheel mounted in the housing, and a feeding member mounted on the housing. Thus, the hooks of the feeding member are hooked onto the transverse stubs of the housing, the movable plate of the feeding member is inserted into the slideway of the housing, and the threaded rod is screwed into the housing and extended through the movable plate of the feeding member to secure the feeding member to the housing, so that the feeding member is mounted on and detached from the housing easily and quickly by rotation of the threaded rod, thereby facilitating the user assembling and disassembling the feeding member.

Abstract: A baseball and softball practicing apparatus includes a housing, a first feeding member mounted on the housing and having a first entrance, a second feeding member detachably mounted in the first feeding member and having a second entrance, and a locking device mounted on the first feeding member and detachably engaged with the second feeding member to lock the second feeding member in the first feeding member. Thus, the second feeding member is mounted on and removed from the first feeding member, so that the practicing apparatus can be used to select and change the baseball and the softball rapidly, thereby facilitating a user practicing the baseball or the softball.
