Abstract

The invention provides an upper entry type barrel tennis ball ejection device and a method thereof. The controller controls the motor to drive the rotating shaft to rotate and the rotating shaft to drive the baffle to rotate. The tennis balls in the storage bin enter the independent space one by one in the process of the baffle rotating. With the baffle rotating, the tennis balls are sent into theball outlet channel, and the tennis balls pass through the ball outlet channel and connect the channel to the ballistics. The controller controls the spring in the spring compressor to eject. In thespring ejection process, the emitter ejects and pushes the tennis ball to be launched. The tennis learners strike back according to the direction of the tennis ball, and hit back the ball to the baffle. After the tennis ball is fired, the controller controls the spring in the compressor to return to the spring compressor and wait for the next tennis ball to be fired. The stiffening barrel type tennis ejection device provided by the invention has the advantages of simple structure and convenient use, is helpful for tennis learners to carry out training, improves the training effect and tennis skills of tennis learners, fully exercises the reaction ability of athletes, and lightens the work intensity of coaches at the same time.

Description

technical field [0001] The invention belongs to the field of tennis training, and in particular relates to a lifting cylinder type tennis ejection device and a method thereof. Background technique [0002] Tennis is a ball game usually played between two singles players or two pairs. A player hits a tennis ball with a tennis racket through the net on a tennis court. In the process of learning tennis, it is highly dependent on the comprehension of the learner, and the training of tennis comprehension cannot be passed on through action demonstrations. [0003] Tennis learners need to overcome the following two difficulties in the contact process. One is to release the maximum strength of the body and hit the fastest and heaviest ball when the whole body is relaxed; Next, hit the desired landing point. And if these two difficulties are combined, it is how to hit the desired landing point with the greatest strength. If you can do this step, you can advance to the ranks of mas...
