Ball-Loading Device For Fee Fall Experiment

A ball-loading device for free-fall experiments, comprising an inlet tube (1) and a shell (2), wherein

• an end of the inlet tube (1) is connected to a first end of the shell (2);
• the shell (2) comprises a ball channel in an interior, a second end of the shell (2) forms a ball outlet (4), the first end of the shell (2) is disposed higher than the second end of the shell(2), a bracket (5) is rotatably connected to the shell (2);
• a first blocking part and a second blocking part are disposed on the bracket (5), the first blocking part corresponds to the ball outlet (4), the second blocking part corresponds to the ball channel;
• and
• when the bracket (5) rotates to different positions around the shell (2), the first blocking part switches to block the ball outlet (4), or the second blocking part switches to block the ball channel.
