Problems solved by technology

[0003] At present, most of the two-color balls are drawn from the box by hand. During the drawing process, in order to ensure fairness and randomness, people will use their hands to stir the two-color balls before drawing, making the two-color balls more chaotic. It needs to be stirred by hand before each extraction, which is troublesome, and because the number of times people stir each time is different, it is easy to affect the fairness of the extraction

Embodiment 1

[0024] A kind of double-color ball extraction device for random selection, such as Figure 1-5 As shown, it includes a base plate 1, a cylindrical shell 2, a guide rod 3, a guide sleeve 4, a first spring 5, a pressure plate 6, a feed pipe 7, an L-shaped contact rod 71, a mixing assembly 8 and an extraction assembly 9, and the base plate 1. A cylindrical shell 2 is installed in the middle of the top, and a feed pipe 7 is connected to the left side of the top of the cylindrical shell 2. The feed pipe 7 communicates with the inside of the cylindrical shell 2. The top left side of the bottom plate 1 is symmetrically fixed with a The guide rod 3 is provided with a sliding guide sleeve 4 on the guide rod 3, and a mixing assembly 8 is provided between the right side of the front guide sleeve 4 and the center of the cylindrical housing 2, and the mixing assembly 8 and the cylindrical housing 2 Cooperate, the first spring 5 is wound around the bottom of the guide sleeve 4 and the lower...

Embodiment 2

[0031] On the basis of Example 1, such as image 3 and Figure 4 As shown, a partition assembly 10 is also included. The partition assembly 10 includes a support sleeve 1001, a second slide bar 1002, a third spring 1003, a partition bar 1004, a contact wheel 1005 and a special-shaped block 1006, and the left and right sides of the material guide block 907 The bottom is fixedly connected with a second slide bar 1002, and a support sleeve 1001 is slidingly provided on the second slide bar 1002. A third spring 1003 is connected between the inner surface of the support sleeve 1001 and the outer surface of the material guide block 907. The third spring 1003 is set on the second slide bar 1002, and the front side of the support sleeve 1001 is fixedly connected with a partition bar 1004, and the inner ends of the left and right side partition bars 1004 run through the upper part of the material guide block 907 to cooperate with it, and the left and right sides of the partition bar 10...

Embodiment 3

[0034] On the basis of embodiment 1 and embodiment 2, such as figure 1 , figure 2 and Image 6 As shown, push plate 11, torsion spring 12 and collection frame 13 are also included, and push plate 11 is hinged on the lower part of the rear side of material guide block 907, and the front portion of push plate 11 is positioned in material guide block 907, and push plate 11 and material guide block The hinge of 907 is connected with torsion spring 12, and collection frame 13 is installed in the middle front part of bottom plate 1 top, and collection frame 13 is positioned at push pedal 11 front side, and collection frame 13 front side bottom has holes.

[0035] When the support plate 906 drives the two-color ball to move downward, the support plate 906 moves downward to contact the push plate 11, the support plate 906 drives the push plate 11 to swing backward, the torsion spring 12 stretches, and then the support plate 906 continues to move down and push When plate 11 is disen...

Abstract

The invention relates to a drawing device, in particular to a double-color ball drawing device for random drawing. The technical problem is how to design a kind of double-color ball extracting device that can be more convenient for people to draw, and can also stir the double-color ball, improve randomness, and not affect fairness. A double-color ball extraction device for random drawing, comprising: a bottom plate, a cylindrical shell is installed in the middle of one side of the bottom plate, and a feeding pipe is connected to the side away from the bottom plate, and the feeding pipe is connected to the column connected in the shell. In the present invention, by throwing the two-color balls into the cylindrical shell and pushing the pressure plate to move downward, the n-type scraper can stir the two-color balls. At the same time, when the L-shaped contact rod contacts the contact block to move downwards, one of the two-color balls is The support plate is driven into the material guide block, and the extraction is completed. There is no need to stir the two-color balls by hand, which is troublesome and does not affect the fairness.

Description

technical field [0001] The invention relates to a drawing device, in particular to a double-color ball drawing device for random drawing. Background technique [0002] Sphere: The spatial geometry formed by a semicircle rotating around the straight line where the diameter is located is called a sphere, or sphere for short, and the radius of the semicircle is the radius of the sphere. A sphere is a three-dimensional figure with one and only one continuous curved surface, and this continuous curved surface is called a sphere. The orthographic projection of the sphere on any plane is a circle of equal size, and the diameter of the projection circle is equal to the diameter of the sphere. When people hold events for lottery draws, they like to use two-color balls for lottery draws, so they need to draw two-color balls. [0003] At present, most of the two-color balls are drawn from the box by hand. During the drawing process, in order to ensure fairness and randomness, people w...
