Description

Technical Field

[0001] This utility model relates to the field of ball-shaking machine technology, specifically to an automatic ball-shaking machine. Background Technology

[0002] A ball-drawing machine is used to draw various prizes or select numbers. It contains balls of different colors, which fall out after being operated in a specific manner. The color of the falling ball has a certain degree of randomness and uncontrollability. Therefore, these characteristics of the lottery machine ensure the fairness of the lottery results. It is suitable for courts, government agencies, enterprises, and other units that need to demonstrate fairness and impartiality, or for all activities involving lottery draws or number selection. National lottery institutions use lottery machines for drawing prizes, and provincial-level courts and relevant public disclosure departments all use lottery machines as a symbol of fairness and impartiality. Existing ball-drawing machines are generally divided into stirring-type ball-drawing machines and blowing-type ball-drawing machines. The stirring-type ball-drawing machine uses a rotating stirring shaft to make all the balls move randomly, and the ball that falls into the outlet is the lucky ball. However, current stirring ball-shaking machines usually require manual cranking of the handle to start the ball-pulling motor, which in turn drives the stirring shaft to make the balls move randomly. This method is not only complex in structure and increases labor costs, but also increases the possibility of cheating by the lottery personnel. In addition, after each ball falls, the color needs to be identified manually and announced. There is a certain probability of errors in this process, and manual identification has a certain lag, so the lottery results cannot be known to people immediately.

[0003] In view of this, it is very necessary to develop an automatic ball-shaking machine with a simple structure that can automatically identify the color of the ball. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic ball-shaking machine, so as to reduce human intervention in the ball-shaking process, avoid errors and delays in human identification of ball color, and effectively ensure the fairness, accuracy and timeliness of the prize results.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] An automatic ball-shaking machine includes a frame, a rotating ball cover, a drive mechanism for driving the rotating ball cover to rotate, and a color recognition mechanism. The drive mechanism includes a slewing bearing and a drive motor. The outer ring of the slewing bearing is fixedly connected to one side of the frame, and the inner wall of the inner ring of the slewing bearing is provided with an annular toothed portion. The drive motor is fixedly mounted on the other side of the frame, and a gear is fixedly mounted on the output shaft of the drive motor, the gear meshing with the annular toothed portion. The rotating ball cover is mounted on the inner ring of the slewing bearing, and a plurality of stirring blades are evenly distributed along its circumference on the inner wall of the rotating ball cover. The frame is provided with a ball-discharging guide groove, and the color recognition mechanism is provided on the frame.

[0007] In a preferred embodiment of this utility model, a ball-scoring detection photoelectric sensor is provided on the bottom of the ball-out guide groove.

[0008] In a preferred embodiment of the present invention, the stirring blade includes two symmetrically arranged first stirring blades and two symmetrically arranged second stirring blades, wherein the two first stirring blades and the two second stirring blades are staggered in the circumferential direction of the rotating spherical cover.

[0009] More preferably, the ends of both the first and second stirring blades are bent.

[0010] In a preferred embodiment of this utility model, the length of the first stirring plate is greater than the length of the second stirring plate.

[0011] In a preferred embodiment of this utility model, the frame is provided with a ball recovery hole, and a ball recovery guide groove is installed on the frame on the opposite side of the rotating ball cover. The ball recovery hole is connected to the ball discharge guide groove through the ball recovery guide groove.

[0012] More preferably, a ball-blocking electromagnet and a recycling electromagnet are provided on the top wall of the recycling guide trough; the color recognition mechanism is installed on the side wall of the recycling guide trough and located below the recycling electromagnet; the ball-blocking electromagnet is located between the recycling electromagnet and the ball-discharging guide trough.

[0013] More preferably, the bottom plate of the recycling guide trough is inclined relative to the horizontal plane.

[0014] In a preferred embodiment of the present invention, the present invention further includes a controller; the drive motor is electrically connected to and controlled by the controller; the goal detection photoelectric eye and the color recognition mechanism are respectively signal-connected to the controller.

[0015] In a preferred embodiment of this utility model, the ball-blocking electromagnet and the recovery electromagnet are each connected to a relay; the relay coil terminal is electrically connected to the controller, and the relay control terminal is electrically connected between the ball-blocking electromagnet and the power supply and between the recovery electromagnet and the power supply.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The automatic ball-shaking machine provided by this utility model drives a rotating ball cover to rotate via a drive motor and gears. During the rotation of the ball cover, the stirring blades cause the balls inside the rotating ball cover to move randomly, so that a certain probability of the balls fall into the ball guide groove. At the same time, after the color recognition mechanism identifies the color of the ball, the controller or display can announce the lottery result immediately. The entire ball-shaking process is fully automated, which greatly reduces the human intervention in the ball-shaking process, avoids the possibility of cheating in the ball-shaking process, and improves the credibility of the lottery. At the same time, the automatic identification of the ball color and timely announcement can effectively avoid the problems of error and lag in the manual identification of ball color, and effectively ensure the fairness, accuracy and timeliness of the lottery results.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-5 As shown, the automatic ball-sharing machine of this utility model includes a frame 1, a rotating ball cover 2 for accommodating the lottery balls, a drive mechanism for driving the rotating ball cover 2 to rotate, and a color recognition mechanism 8 for color recognition of the balls. The rotating ball cover 2 is rotatably mounted on the frame 1. The drive mechanism is mounted on the frame 1 and is connected to the rotating ball cover 2 for transmission, causing the rotating ball cover 2 to rotate clockwise or counterclockwise around its axial direction under the drive of the drive mechanism, thereby moving the balls. The color recognition mechanism 8 is mounted on the frame 1.

[0026] Specifically, such as Figure 4 As shown, the frame 1 has a mounting boss protruding towards the rotating ball cover 2. The mounting boss has a mounting hole 101, a ball recovery hole 102, and a connecting through hole 103. The mounting hole 101 is higher than the ball recovery hole 102. A ball discharge guide groove 3 is installed in the mounting hole 101. The ball in the ball discharge guide groove 3 can be recovered into the rotating ball cover 2 through the ball recovery hole 102. The connecting through hole 103 is used for the drive mechanism to pass through and be connected to the rotating ball cover 2. The rotating ball cover 2 is preferably a transparent cylindrical structure. One end of the rotating ball cover 2 has an opening, and the other end is fitted with a cover. The open end of the rotating ball cover 2 is connected to the drive mechanism, forming a space between the rotating ball cover 2 and the mounting boss of the frame 1 to accommodate the ball. Figure 2 As shown, a plurality of stirring blades 4 are evenly distributed along the circumference of the inner wall of the rotating spherical cover 2. When the rotating spherical cover 2 rotates, the stirring blades 4 drive the spheres to move randomly, so that a certain probability of the spheres falls into the ball guide groove 3. Figure 4 As shown, the drive mechanism includes a slewing bearing 5 and a drive motor 6. The slewing bearing 5 consists of an outer ring 501 and an inner ring 502, which are rotatably connected by rollers. The outer ring 501 of the slewing bearing 5 is mounted on the side of the frame 1 with a rotating ball cover 2 via bolts or other connecting parts. The inner wall of the inner ring 502 of the slewing bearing 5 has an annular toothed portion 503. The drive motor 6 is fixedly mounted on the other side of the frame 1. A gear 7 is fixed on the output shaft of the drive motor 6. The gear 7 passes through the connecting through hole 103 of the frame 1 and meshes with the annular toothed portion 503 of the inner ring 502. The rotating ball cover 2 is detachably connected to the inner ring 502 of the slewing bearing 5 via bolts or other connecting parts. Thus, the inner ring of the slewing bearing 5 can drive the rotating ball cover 2 to rotate under the drive of the drive motor 6. A color recognition mechanism 8 can be mounted on the frame 1 or in the ball guide groove 3 to identify the color of the ball in the ball guide groove 3.

[0027] With the above scheme, when the drive motor 6 drives the gear 7 to rotate the rotating ball cover 2, the stirring plate 4 causes the balls inside the rotating ball cover 2 to move randomly, so that a certain probability of the balls fall into the ball guide groove 3. At the same time, after the color recognition mechanism 8 identifies the color of the ball, the lottery result can be announced by the controller or display immediately. The entire ball-rolling process is fully automated, which greatly reduces the human intervention in the ball-rolling process, avoids the possibility of cheating in the ball-rolling process, and improves the credibility of the lottery. At the same time, the automatic identification of the ball color and timely announcement can effectively avoid the problems of easy error and lag in the manual identification of the ball color, and effectively ensure the fairness, accuracy and timeliness of the lottery results.

[0028] In some embodiments, the stirring blades 4 include two symmetrically arranged first stirring blades 401 and two symmetrically arranged second stirring blades 402, which are staggered in the circumferential direction of the rotating spherical cover 2. More preferably, the length of the first stirring blades 401 is greater than the length of the second stirring blades 402. By using stirring blades 4 of different lengths to stir the balls, the balls can be mixed more evenly, further improving the fairness and impartiality of the ball shaking process. More preferably, the ends of both the first stirring blades 401 and the second stirring blades 402 are bent, and both are bent clockwise or counterclockwise along the rotating spherical cover 2. More preferably, both ends of the first stirring blade 401 are bent, and the bending directions of the two ends are opposite.

[0029] In some embodiments, a recovery guide trough 9 is installed on the opposite side of the rotating ball cover 2 on the frame 1, and the ball recovery hole 102 communicates with the ball exit guide trough 3 through the recovery guide trough 9. Preferably, the bottom plate of the recovery guide trough 9 is inclined relative to the horizontal plane. A ball blocking electromagnet 10 and a recovery electromagnet 11 are provided on the top wall of the recovery guide trough 9, and the ball blocking electromagnet 10 is located between the recovery electromagnet 11 and the ball exit guide 3. Specifically, the ball blocking electromagnet 10 is located at the connection between the ball exit guide 3 and the recovery guide trough 9 to prevent multiple balls from falling into the ball exit guide 3 when the ball is shaken. More preferably, a ball-scoring detection photoelectric sensor 12 is provided on the bottom of the ball exit guide 3. The recovery electromagnet 11 is installed in the middle position of the recovery guide 9, and the color recognition mechanism 8 is installed on the side wall of the recovery guide 9 and located below the recovery electromagnet 11. This utility model also includes a controller (not shown); the drive motor 6 is electrically connected to the controller and controlled by the controller; the ball-scoring detection photoelectric sensor 12 and the color recognition mechanism 8 are respectively signal connected to the controller. Each of the ball-blocking electromagnet 10 and the retrieval electromagnet 11 is connected to a relay. The relay coil of the ball-blocking electromagnet 10 is electrically connected to the controller, and the control terminal is electrically connected between the ball-blocking electromagnet 10 and the power supply. The relay coil of the retrieval electromagnet 11 is electrically connected to the controller, and the control terminal is electrically connected between the retrieval electromagnet 11 and the power supply. The working process of this utility model is as follows: When the ball-scoring detection photoelectric sensor 12 detects a ball falling into the ball-out guide groove 3, it sends a ball-scoring signal to the controller. The controller controls the relay to de-energize the ball-blocking electromagnet 10, thereby opening the ball-blocking electromagnet 10. This allows the ball to roll backward along the inclined bottom plate of the retrieval guide groove 9 until it is blocked by the retrieval electromagnet 11. At this time, the color recognition photoelectric sensor identifies the color of the ball and sends the color signal to the controller for publication. Simultaneously, the controller controls the relay to de-energize the retrieval electromagnet 11, thereby opening the retrieval electromagnet. The ball continues to roll down along the retrieval guide groove 9, passes through the retrieval ball hole 102, and is retrieved into the rotating ball cover 2.

[0030] As can be seen, the automatic ball-shaking machine of this utility model can realize the automated operation of ball shaking and lottery result announcement, greatly reducing human intervention in the ball shaking process, avoiding the possibility of cheating in the ball shaking process, improving the credibility of the lottery, and avoiding the problems of easy error and lag in manual ball color identification, effectively ensuring the fairness, accuracy and timeliness of the lottery results.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
