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 with 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 1...

Embodiment 3

[0034] On the basis of embodiment 1 and embodiment 2, such as figure 1 , figure 2 with 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 dise...

Abstract

The invention relates to a drawing device, relates to a double-color ball extracting device, particularly relates to a double-color ball extracting device for random extraction and selection, and aimsto design a double-color ball extracting device for random extraction and selection, which is more convenient for people to extract bicolor balls, can stir the bicolor balls, improves randomness anddoes not influence fairness. The double-color ball extracting device for random extraction and selection comprises a bottom plate, wherein a cylindrical shell is installed in the middle of one side ofthe bottom plate, a feeding pipe is connected with a side, away from the bottom plate, of the bottom plate, and the feeding pipe is communicated with the interior of the cylindrical shell. The deviceis advantaged in that double-color balls are thrown into the cylindrical shell, a pressure plate is pushed to move downward so that an n-type scraper stirs double-color balls, and meanwhile, when anL-shaped contact rod makes contact with a contact block to enable the L-shaped contact rod to move downwards, one of the double-color balls is driven by a supporting plate into a material guiding block, extraction is completed, the two-color balls do not need to be stirred by hands of people, trouble is avoided, and fairness is not affected.

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...
