Description

A ball passing device for spiking training of air volleyball

technical field

The invention relates to the field of sports training equipment, in particular to a ball passing device for spiking training of air volleyball.

Background technique

Air volleyball is a mass sport that integrates sports, leisure and entertainment. As a new sport, it has been favored by more and more boys and girls. Its play and scoring methods are basically the same as competitive volleyball. The weight of the gas volleyball for competition is about 120 grams, which is 100-150 grams lighter than that of ordinary volleyball; Air volleyball is a mass volleyball activity native to my country. Because the exercise is moderate and not intense, air volleyball can be mixed with men and women to participate, and it is suitable for people of all ages to carry out physical fitness activities. An important part of air volleyball training is spiking training. The spiking training of ordinary volleyball requires manual coordinating and passing the ball, and then the trainer can conduct targeted spiking training on the ball that is passed. However, such a spiking and passing It needs the cooperation of additional personnel, and the efficiency is low, so it is impossible to carry out spiking training efficiently; and for the spiking training of ordinary volleyball, ordinary volleyball server can also be used for spiking and passing, which can greatly improve the performance of ordinary volleyball. The spiking training has the passing efficiency. However, due to the hard texture of ordinary volleyball, the ordinary volleyball server that matches it for spiking and serving has a fast serving speed and high serving force, which is not suitable for automatic serving in air volleyball. Using an ordinary volleyball server to serve air volleyball will cause the air volleyball to be damaged, unstable and even fail due to its light weight and soft texture.

When the bat 10 just touches the air volleyball 18 located at the bottom of the V-shaped channel, the side wall of the bat 10 is in contact with the air volleyball located at the bottom of the V-shaped channel. The 18 spherical surfaces are just tangent, so that the bat at the moment of hitting the ball directly hits the center of the air volleyball.

Further, the base includes a turntable 1 and a base 13, the turntable 1 is arranged on the base 13, and the base 13 is provided with a second motor 14 for providing rotational power to the turntable 1. The second motor 14 is a stepper motor, and the second motor 14 is signal-connected to the second motor controller 15. The second motor controller 15 is used to control the opening and closing of the second motor 14, and to control the first motor 14. The two motors 14 rotate back and forth within the set rotation angle; the first bracket 2 and the second bracket 12 are both fixed on the turntable 1 . Through the back and forth rotation of the turntable, the azimuth angle of the hit air volleyball can be adjusted, so as to better perform the air volleyball spike training when the ball comes from different directions.

Further, the bottom of the base 13 is provided with a roller 16 with a braking mechanism 17, the device of the present invention can be conveniently moved by the roller, and the device of the present invention can be stably placed at a set location by the braking mechanism.

Further, each bat 10 is provided with elastic layers with different degrees of softness and hardness, and the elastic layer on each bat 10 is used for hitting different heights by co-action with the spring 8 corresponding to the bat 10 where it is located. The elastic layer is also used to avoid damage to the air volleyball 18 caused by the direct contact of the hard bat 10 with the air volleyball 18 when hitting the air volleyball 18 .

Further, the method of passing the ball of the air volleyball spiking training ball passing device is: placing the air volleyball spiking training ball passing device on one side of the air volleyball court, and launching the air volleyball output fairway 5 toward the ball. The direction of the air volleyball court, and then the first motor 7 is activated by the first motor controller 11 to rotate, thereby driving the bats 10 to pass through the V-shaped notch 6 in turn, so as to connect the different reset forces. Each bat 10 of the spring 8 hits the air volleyball 18 that continuously rolls down from the air volleyball conveying channel 4 to the bottom of the V-shaped channel with different strengths in turn, so that the hit air volleyball 18 is launched along the air volleyball output fairway. 5 is continuously launched and sent to the top of the air volleyball court at different pass throwing heights, so as to supply the air volleyball spike trainer to conduct spike training, and the air volleyball spike trainer will launch the air volleyball court where The air volleyball 19 is spiked so that it goes over the air volleyball net 19 and is dropped to the opposite air volleyball court.
