Emitter with 360-degree cradle head and controllable trajectory direction track

Abstract

The invention discloses an emitter with a 360-degree cradle head and a controllable trajectory direction track. The emitter comprises a ball feeding device, an emitting device, a pitching assembly with adjustable angle, the 360-degree cradle head, and a pipe connecting assembly. The ball feeding device comprises a ball cabin and a movable ball falling port; the ball cabin comprises a funnel type frame, and a plurality of ball storage channels inclinedly arranged in the frame in parallel; an infrared emission head is arranged on the higher end of each ball storage channel; the movable ball falling port comprises a linear movement mechanism and a sliding door assembly; infrared receiving head matched with the infrared emission heads are also arranged on the sliding door assembly; the emitting device is arranged on the pitching assembly; and the pitching assembly is arranged on the 360-degree cradle head rotating around a Z axis. The emitter with the 360-degree cradle head and the controllable trajectory direction track provided by the invention is economical, practical, lower in ball blockage rate, flexible and adjustable in range, emission angle and emission direction, and high in anti-interference capability of an emission curve, and can meet the requirement of tennis emission in any angle and range in a 360-degree direction.

Description

technical field [0001] The invention relates to a learning and sporting article, in particular to a tennis ball launcher with a 360-degree platform and a controllable ballistic trajectory. Background technique [0002] Tennis has now become a popular ball game all over the world, and is deeply loved by outdoor sports people. With the rapid development of tennis, many colleges and universities have also launched tennis courses and tennis majors, and tennis is becoming more and more popular among students. Most of the students generally need at least one sparring partner when they are training. However, the lack of sparring staff often leads to the inability to carry out the training or the training effect is not increased. Many colleges and universities will use tennis training machines to train students. However, the current mainstream tennis launchers on the market still shoot tennis balls through friction, but there are still shortcomings, such as relatively short range u...

Problems solved by technology

Most of the students generally need at least one sparring partner during training, however, often due to lack of sparring personnel, the training cannot be carried out or the training effect is not increased.

Many colleges and universities will use tennis training machines to train students. However, the current mainstream tennis launchers on the market still shoot tennis balls through friction, but there are still shortcomings, such as relatively short range under certain circumstances, limited angle launch and launch. The anti-interference ability of the curve is weak, the cost is high, and the ball is often jammed, and the traditional tennis training machine either does not have a rotating head, so that the training methods cannot be diversified. Most of the rotating heads use a turntable structure. The turntable has a large gap and is affected by the vertical downward force. The performance of the force is not good, it is easy to expand the gap, resulting in a decrease in accuracy, which affects the control effect and directly leads to inaccurate launch

It greatly affects the progress of tennis training, and even affects the mood of the trainer, affecting the training effect
