Document Type and Number:
WIPO Patent Application WO/2023/051429
Kind Code:
A1
Abstract:
A ball feeding device for a free fall experiment, the device comprising a ball intake pipe (1) and a ball intake housing (2). The tail end of the ball intake pipe (1) is in communication with a first end of the ball intake housing (2); a ball passage is provided inside the ball intake housing (2); a ball outlet (4) is formed at a second end of the ball intake housing; the first end of the ball intake housing (2) is arranged higher than the second end thereof; a material blocking bracket (5) is rotatably connected to the ball intake housing (2); a first blocking portion and a second blocking portion are connected to the material blocking bracket (5); the first blocking portion corresponds to the ball outlet (4), and the second blocking portion corresponds to the ball passage; and when the material blocking bracket (5) rotates to different positions around the ball intake housing (2), the state in which the first blocking portion blocks the ball outlet (4) and the state in which the second blocking portion blocks the ball passage are switched, such that balls completing the free fall experiment can be automatically and orderly fed in sequence to be transported to an initial point for the next experiment, without needing an on-site operation and manually collecting the falling balls by an operator, thus the orderly progress of the experiment is guaranteed and the efficiency of the experiment is improved.
