Advanced mathematics probability demonstration device

Abstract

The present invention discloses an advanced mathematics probability demonstration device. The device comprises a pedestal, the upper side wall of the pedestal is fixedly connected with a demonstration frame which employs an opening structure at the upper side and is made of transparent plastic, the inner bottom wall of the pedestal is fixedly connected with a first separator, a second separator and a third separator in order, a second servo motor drives an electromagnetic loop to rotate to generate magnetism and perform attraction for an ejection plate, a flexible spring is compacted, when the second servo motor is closed, the magnetism of the electromagnetic loop can disappear, the ejection plate is popped up under the elastic force in the recovery of the flexible spring, coins perform parabolic motion to achieve upcast of the coins so as to replace manual work to cast the coins upwards, save time and labor and improve the casting efficiency; the coins after casting are dropped on aconveyor, students and teachers perform statistics, the coins can be conveyed by the conveyor to enter a coin collection cavity through a coin dropping port for collection so as to eliminate manual collection and so as not to influence on continuous observation and collection after collection.

Description

technical field [0001] The invention relates to the technical field of advanced mathematics auxiliary teaching aids, in particular to an advanced mathematics probability demonstration device. Background technique [0002] In advanced mathematics, probability is a difficult concept to understand. Teachers generally use the method of flipping a coin to count the number of times the coin lands on the front and back sides, and divide the total number of coin flips above to obtain the probability of the coin’s front and back sides, to assist students understand. [0003] In the prior art, the teacher needs to repeatedly toss up the coins, and collect them after each count. The whole demonstration process is time-consuming and laborious, resulting in low teaching efficiency. Contents of the invention [0004] The purpose of the present invention is to solve the problem in the prior art that the teacher needs to repeatedly toss up the coin, and it needs to be collected after eac...
