Embodiment 1

[0021] refer to Figure 1-Figure 6 , a double-color ball drawing device for random drawing, including a chassis 1, a connecting frame 2, a support column 3, a driving mechanism, a two-way frame 7, a collection frame 8, a support groove plate 12, a circular turntable 1301, a cylinder 1302, an arc Shape cover 16, cover 1601 and opening and closing mechanism, chassis 1 top front side is fixedly connected with connecting frame 2, and connecting frame 2 top front side has the through hole that can make two-color ball drop, and connecting frame 2 and chassis 1 top left side There is a drive mechanism between them, the middle part of the rear side of the top of the chassis 1 is fixedly connected with a support column 3, the top of the support column 3 is fixedly connected with a support groove plate 12, the top of the support groove plate 12 is fixedly connected with an arc-shaped cover 16, and the top middle of the arc-shaped cover 16 A cover 1601 is provided, and the cover 1601 coo...

Embodiment 2

[0028] refer to Figure 4 Compared with Embodiment 1, the main difference of this embodiment is that in this embodiment, a torsion spring 601 is also included, and a torsion spring 601 is provided at the hinge between the bidirectional frame 7 and the bearing seat 5 .

[0029] When the first two-color ball fell to one side of the two-way frame 7, the two-color ball drove the two-way frame 7 to swing, and the torsion spring 601 stretched, the second two-color ball also fell to the other side of the two-way frame 7, and the first two-color ball fell. When falling into the collection frame 8, due to the effect of the torsion spring 601, the two-way frame 7 swings back, and the second two-color ball drives the two-way frame 7 to swing to the opposite position, and the second two-color ball also falls into another collection frame 8 , due to the effect of the torsion spring 601, the two-way frame 7 swings and resets. Like this, can avoid that two-way frame 7 can't reset and affect...

Abstract

The invention relates to a drawing and selecting device, in particular to a double-color ball drawing and selecting device for random drawing and selecting. The technical problem is how to design a two-color ball extracting device for random drawing, which can randomly drawing two-color balls, improves fairness and is labor-saving. A double-color ball drawing and selecting device for random drawing and selecting comprises a base plate, a connecting frame is fixedly connected to the base plate, holes are symmetrically formed in one side of the connecting frame, and a circular rotary disc is arranged on the side, away from the base plate, of the connecting frame. Double-color balls are poured into the arc-shaped cover, and the motor is started to rotate reversely, so that the concave baffledoes not block the double-color balls, and the double-color balls fall into the cylinder and then are driven to the front side to fall into the collecting frame; according to the invention, the double-color balls are drawn out through the device, fairness is improved, the cheating phenomenon is avoided, and labor is saved.

Description

technical field [0001] The invention relates to a lottery device, in particular to a double-color ball lottery device for random lottery. Background technique [0002] Two-color balls: spheres of different colors, mostly used for playing games or other purposes. [0003] At present, people put all the two-color balls in a box, and then put their hands into the box to grab the two-color balls for selection. In this way, it is more laborious and needs to move hands constantly, which is troublesome. Feeling unfair, there will be marks on the two-color balls, causing people to only need to grab the marked two-color balls. [0004] Therefore, there is a need for a double-color ball drawing device that can randomly draw two-color balls to improve fairness and save labor, so as to solve the problems in the prior art. Contents of the invention [0005] In order to overcome the shortcoming that human hands reach into the box to pick out the two-color balls, so that it is laboriou...
