Embodiment 1

[0038] A kind of auxiliary teaching equipment for mathematics probability course, comprising a support frame 1, a casing 2, a storage ball 3, a first rotating shaft 4, a runner 5, a discharge pipe 6, a feeding mechanism 7, a scrambling mechanism 8 and a shielding mechanism 9 , see Figure 1-Figure 9 As shown, the upper parts of the left and right sides of the support frame 1 are welded with a casing 2, and the interior of the casing 2 is rotatably provided with a first rotating shaft 4, and the first rotating shaft 4 is provided with a storage ball 3. When the storage ball 3 rotates, it can Disorganize the positions of the small balls in the storage ball 3. The storage balls 3 are all located inside the casing 2, the outer side of the first rotating shaft 4 is provided with a runner 5, and the left and right sides of the upper part of the support frame 1 are provided with discharge pipes 6. One end of the material pipe 6 is connected to the outer shell 2 on the same side.

Embodiment 2

[0044] On the basis of Embodiment 1, a placement mechanism 10 is also included, and the placement mechanism 10 includes a storage tank 101, a first limit rod 102, a second movable block 103 and a first spring 104. See figure 1 , Figure 10 and Figure 11 As shown in the figure, storage tanks 101 are symmetrically welded on the left and right sides of the upper part of the support frame 1. People can put the balls into the storage tank 101 to store the balls. The storage tank 101 is provided with a first limit The position rod 102 is slidably provided with a second movable block 103 between the outer sides of the two first limit rods 102 on the same side. The second movable block 103 is slidably connected with the storage tank 101 on the same side. The second movable block There are first springs 104 between the inner side of 103 and the first limit rods 102 on the same side. The number of the first springs 104 is eight, and the first springs 104 are all wound around the first...

Abstract

The invention relates to auxiliary teaching equipment, in particular to auxiliary teaching equipment for a mathematical probability class. The invention aims to provide the auxiliary teaching equipment for the mathematical probability class, which can prevent a small ball from flying out during movement. The auxiliary teaching equipment for the mathematics probability class comprises a supporting frame, shells, storage balls, first rotating shafts, rotating wheels, a discharging pipe and the like, the shells are arranged on the upper portions of the left side and the right side of the supporting frame, the first rotating shafts are rotationally arranged in the shells, the storage balls for disorganizing small balls are arranged on the first rotating shafts, and the rotating wheels are arranged on the first rotating shafts. The storage balls are located in the shells, rotating wheels are arranged on the outer sides of the first rotating shafts, discharging pipes are arranged on the left side and the right side of the upper portion of the supporting frame, and one ends of the discharging pipes are connected with the shells on the same sides. Under the action of the first movable block, when the small balls move, the first movable block can block the small balls in the storage balls, and the small balls are prevented from flying out.

Description

technical field [0001] The invention relates to an auxiliary teaching device, in particular to an auxiliary teaching device for mathematics probability class. Background technique [0002] At present, the existing teaching equipment for mathematical probability theory generally uses random events to count probabilities to realize the teaching of probability theory classrooms. Due to the relatively simple method of probability statistics, the probability is generally calculated by tossing a coin and counting the number of heads and tails, and the error is relatively small. It is not suitable for the actual teaching of students. [0003] Patent application CN110874971A, published on 20200310, discloses a kind of auxiliary teaching equipment for mathematics probability class, including a box body, a chute is fixedly installed on the top inner wall of the box body, and an inlet is fixedly installed on the top of the box body, A recovery chamber is fixedly installed at the botto...
