Description

Table tennis ball collecting and processing method for training

Technical Field

The invention belongs to the technical field of sports equipment, and particularly relates to a table tennis ball collecting and processing method for training.

Background

When the athletes do table tennis training, a large amount of table tennis balls are used. The table tennis is scattered on the training ground and needs to be collected for reuse. At present, the adopted method mainly comprises manual bare-handed picking or broom collection, the manual bare-handed picking needs frequent stooping and knee bending, the defects of high labor intensity and low efficiency exist, and table tennis balls collected by the broom can have a large amount of dust. Meanwhile, after the used table tennis is hit by the racket for many times, the surface of the used table tennis is likely to have sunken and deformed defective goods, so that the elasticity of the table tennis is changed, the speed and the rotation of the table tennis are greatly changed in the training, and the training result is influenced.

Although there is a table tennis ball picker without frequently bending down and bending knees, for example, the chinese utility model patent entitled "table tennis ball picker" with the publication number of CN201356411Y discloses that a spring is respectively arranged on both sides of a table tennis ball mouth at the lower part of the table tennis ball picker, when the ball picking mouth is aligned with a table tennis ball, due to the elasticity of the spring, the table tennis ball pulls the spring open towards both sides, the table tennis ball enters a ball storage cylinder, and the spring restores to the original state to block the table tennis ball, so that the table tennis ball cannot fall off. Although the ball picking device can solve the problem of frequent bending and bending knees, the ball picking device can only pick up the table tennis at the close position when picking up the table tennis, and can only pick up the table tennis by vertically aligning the table tennis, thereby causing unnecessary troubles.

In order to pick up table tennis balls in a large range, the invention discloses a Chinese invention patent with an authorized bulletin number CN102397686B, namely a table tennis ball picking and collecting vehicle, wherein a steel wire rope is pulled by one end of a handle which grips a control rod, so that a ball picking plate rotates fast in a fixed axis mode, and the table tennis balls in a ball picking area are impacted, so that the table tennis balls roll into a collecting bin to pick up the table tennis balls.
