Problems solved by technology

However, the speed at which the existing training equipment sends out the volleyball is less than 120km / h. The reason for the lack of ball speed is that these training equipment use a frictional ball launcher as the volleyball launching device, and the frictional ball launcher has saturated speed when the ball speed does not reach 120km / h. Happening
The serving and spiking speed of the world's high-level athletes can reach 140km / h. Therefore, the friction ball server cannot meet the requirements of high-intensity training for professional athletes.

Abstract

The invention relates to a volleyball launcher. The volleyball launcher is characterized in that a driving gear and a driven gear which have the same external dimension and are mutually meshed are arranged, batting plate springs arranged radially are respectively and fixedly connected on a driving gear shaft and a driven gear shaft, wherein the batting plate spring at the right side fixedly connected on the driving gear shaft and the left side batting plate spring fixedly connected on the driven gear shaft are provided with batting positions which are mutually opposite and both positioned in the same horizontal position, and the batting plate springs move upwards in the batting positions. According to the collision theory, the rotational speed of the motor is improved by a method of launching volleyball through the plate springs in a beating manner, i.e., the ball launching speed can exceed 140 km / h so as to meet the use requirements of high-strength training of the professional volleyball athletes.

Description

technical field [0001] The present invention relates to sports equipment for ball games, in particular to sports equipment for improving volleyball skills, and more particularly to a device for launching volleyballs. Background technique [0002] The volleyball player training equipment can replace the partner trainer to simulate the long-term and stable serve and spike of the game intensity, thereby greatly improving the training level and competition performance of professional volleyball players. Patent No.: 200610085971.6 Name: The invention patent of "Simple Training Device for Volleyball Players" is a training device for volleyball players. However, the speed at which the existing training equipment sends out the volleyball is less than 120km / h. The reason for the lack of ball speed is that these training equipment use frictional ball launchers as the volleyball launching device, and the frictional ball launcher has saturated speed when the ball speed does not reach 12...
