Abstract

The invention relates to probabilistic ball mixing equipment, and particularly relates to pedal-type probabilistic ball mixing equipment for education and teaching. The technical problem is to providepedal-type probabilistic ball mixing equipment which is excellent in randomness, accurate in measurement and convenient to use for education and teaching. The technical scheme is that the pedal-typeprobabilistic ball mixing equipment for education and teaching comprises a horizontal plate, a vertical plate, a first connecting plate, a sliding rod, a sliding sleeve, a connecting rod, a seat cushion, a first bearing pedestal, a screw, a nut, a rear side plate, a second bearing pedestal and the like, wherein the left side of the top of the horizontal plate is connected with the vertical plate,the upper part of the left side surface of the vertical plate is connected with the first connecting plate, and the sliding rod is connected between the left side of the bottom of the first connectingplate and the left side of the top of the horizontal plate. The pedal-type probabilistic ball mixing equipment can mix different colors of balls in a shell through enabling mixing blades to rotate, thereby being capable of disorganizing the different colors of balls. Therefore, the randomness can be improved, and thus the effects of excellent randomness, accurate measurement and convenient use can be achieved.

Description

technical field [0001] The invention relates to a probability ball stirring device, in particular to a foot-operated probability ball stirring device for education and teaching. Background technique [0002] This book mainly collects some achievements since Chengdu Institute of Information Engineering vigorously promoted the reform of education and teaching integration. education management, etc. [0003] Probability is a measure of the possibility of a random event. Generally, a real number between 0 and 1 represents the possibility of an event occurring. The existing probability is to pour balls of different colors into a In an opaque box, the small balls in the box are manually grasped by hand, so the random effect is poor and the measurement is inaccurate. Therefore, it is urgent to develop a foot-operated education and teaching system with good randomness, accurate measurement and easy use. Stir the device with a probability ball. Contents of the invention [0004]...
