Description

A tennis ball pickup machine

technical field

The utility model relates to the field of tennis machinery, in particular to a tennis ball pickup machine.

Background technique

Tennis has become one of people's favorite sports. At present, there is no service or product specialized in intelligent tennis pick-up robot in China, which belongs to the market to be developed. There are about 85,475 tennis courts in my country, with a tennis population of 8.64 million, and the number of sports population is increasing at a rate of 10% to 12% every year, and the market potential is huge. At present, there are only a small number of caddies in the market who specialize in picking up tennis balls, and the personnel are of poor quality. Most of them are temporarily employed in tennis courts. With the popularization and development of tennis players, tennis delivery and ball pick-up machines have also developed to a certain extent. At present, there are many manufacturers of tennis ball machines in the world, and the most representative ones are the tennis machines produced by TUTOR and LOBSTER in the United States. The former uses two high-speed spinning rear wheels to eject the ball. The latter works on the principle of air compression. Most of the tennis ball machines sold on the market are mainly based on the principle of counter-rotating double wheels, and their advantages are fast speed and easy control. The disadvantage is that the serving form is single, which cannot fully meet the needs of some professional players. Both have a common disadvantage: the ball cannot be recovered, which will increase the workload of the trainer.

In contrast to this, the automatic tennis ball pickup machine is made of aluminum as a whole, with a compact structure, beautiful appearance, and simple and convenient use. The speed and frequency of serving can be controlled, and the serving style has been increased, allowing trainers to carry out a variety of different trainings, so that they can get better exercise and training effects. It has the characteristics of high efficiency and no omission, and solves the problem of stuck balls and injured balls as much as possible.

Compared with the prior art, the utility model has the following beneficial effects:

1. The driving wheel is driven by the motor, and then the driving wheel drives the driven wheel through the belt. The driven wheel drives the recovery wheel to work. The baffle at the front of the ball collection device is used to allow more balls to enter the ball collection port. After that, it will enter the recycling box under the pushing action of the recycling wheel. Since the bottom surface of the recycling box is inclined, it is beneficial for the tennis ball to fall to the ball storage box, which can save the number of caddies specializing in picking up the ball and effectively improve the ball picking. efficiency, and reduce the workload of picking up the ball.

2. In order to control the frequency of serving, we have adopted the sheave structure, which can realize intermittent serving.

3. By using four friction wheels to serve, the style of serving is increased, allowing trainers to carry out a variety of different trainings, so that they can get better exercise and training effects.
