Embodiment 1

[0034] like figure 1 and 4 An upper cylinder type tennis ejection device shown includes an ejection cylinder and an ejection base, the ejection base is arranged at the bottom of the ejection cylinder, and the ejection base includes an ejection part and a base; including a temperature detection system, an infrared counting system, communication system, central processing system, cleaning system and ball loading system, the ejection cylinder is connected with a mobile base through a bracket, the bottom of the mobile base is provided with a universal roller, the cleaning system is arranged on the mobile base, the A temperature detection system, a communication system and a central processing system are all arranged on the ejection barrel, the infrared counting system is arranged on the ball loading system, the ball loading system is communicated with the ejection barrel, and the temperature Both the detection system and the infrared counting system are connected with the central...

Embodiment 2

[0045] like figure 1 A kind of push-up cylinder type tennis ejection method shown, described ejection method uses the ejection device in embodiment 1, and described ejection method comprises the following steps:

[0046] S1 cleans the tennis balls in the cleaning system, and places the cleaned tennis balls in the storage box;

[0047] S2 controls the rotation of the motor through the switch, sends the tennis balls in the storage box into the ball delivery cylinder through the scraper, and counts them by the infrared counting system;

[0048] S3 controls the ejection base through the switch to eject the tennis ball in the ejection barrel;

[0049] When the S4 tennis ball is moving in the catapult, the temperature of the catapult is monitored in real time through the temperature detection system, and when the temperature is abnormal, the central processing system controls the alarm;

[0050] S5 summarizes the data through the central processing system and transmits it to the r...

Abstract

The invention relates to the technical field of sports equipment, in particular to a tensioning cylinder type tennis ball ejection device and a method thereof. The tensioning cylinder type tennis ballejection device comprises a temperature detection system, an infrared counting system, a communication system, a central processing system, a cleaning system and a ball feeding system; the temperature detection system is arranged on an ejection cylinder, so that damage to the tennis ball or the ejection device when the temperature of the ejection cylinder wall is abnormal caused by too many ejection times is avoided; the infrared counting system is provided and can monitor the ejection number of the tennis balls in real time, so that loss of the tennis balls caused by the fact that the ball picking number is not consistent with the ejection number is avoided, and counting and check of the tennis ball number are facilitated; the tennis ball on the lower part of a storage box is prodded tothe orifice of a ball feeding cylinder by a scraping plate, the scraping plate automatically returns, and the orifice of the ball feeding cylinder can accommodate only one tennis ball at a time, so one-time movement of the scraping plate is one-time ball feeding and the infrared counting system can perform corresponding counting; and the tensioning cylinder type tennis ball ejection device is simple in structure, convenient and quick in operation and higher in safety, and has more complete functions and higher creativity.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to an upper cylinder type tennis ejection device and a method thereof. Background technique [0002] Tennis is a ball game, usually played between two singles players or a combination of two pairs. A player hits a tennis ball with a tennis racket across the net on a tennis court. The origin and development of tennis can be summed up in four sentences: it was conceived in France, born in the United Kingdom, began to popularize and form a climax in the United States, and is now popular all over the world, known as the second largest ball game in the world. Modern tennis was born in Birmingham, England in the 19th century. It was originally called "lawn tennis". Since then, tennis has developed rapidly. The first Grand Slam Wimbledon Championship was founded in 1877, followed by the United States in 1881. Tennis, the French Open in 1891 and the Australian Open in 1905, the f...
