Abstract

The invention discloses a ball shooting device for tennis training. The ball shooting device comprises an outer shell body, universal wheels, a round groove body, a rotating plate, an end cover, a motor, a connecting hole, a clamping piece, an exhaust hole, a fixed base, a gas spraying opening, a gas conveying channel, an exhaust machine, a connecting pipe and an exhaust groove. The ball shootingdevice is reasonable and simple in structure, low in production cost, convenient to install and complete in function; the motor is a stepping motor, and therefore the precise programming control can be conveniently conducted through an existing control technology, it is ensured that the rotating plate can indirectly rotate by 90 degrees anticlockwise, it is ensured that tennis balls can be intermittently filled and shot, and the ball shooting efficiency is improved; the exhaust machine can vacuumize the exhaust groove, when the connecting hole is located on the upper side, the exhaust hole onthe side face can be communicated with the interior of the exhaust groove, and therefore the tennis balls can be sucked into a ball-shaped clamping groove, and the tennis ball filling speed and quality are greatly improved.
