From the above example, in the prior art, each tile lifting mechanism needs a first motor drive, each tile lifting and carrying mechanism needs a second motor drive, and the tile pushing and lifting device of the whole mahjong machine needs eight motor drives, so that not only is the power wasted and the mechanism composition complicated, but also the phenomenon that the tile lifting mechanism and the tile lifting and carrying mechanism of the same group operate asynchronously to cause faults can occur.
Disclosure of Invention
The application aims to provide a roller coaster type mahjong machine which is characterized in that one motor drives all the mahjong sending mechanisms and the mahjong lifting and bearing mechanisms to work simultaneously.
In order to achieve the above object, the present application has the following technical scheme:
the roller coaster type mahjong machine comprises a base, wherein four tracks surrounded by the side walls of the tracks and the bottom surface of the base are arranged on the base, a card feeding mechanism and a card lifting and bearing mechanism are arranged at each track, the base is rotationally connected with a rotary table, the rotary table is driven by a motor to reciprocate, and the rotary table is provided with a first transmission part for driving the card feeding mechanism to work and a second transmission part for driving the card lifting and bearing mechanism to work.
According to the application, the turntable capable of reciprocally rotating around the base is arranged on the base, the first transmission piece and the second transmission piece drive the turntable to reciprocally rotate, and simultaneously, the first transmission piece and the second transmission piece synchronously rotate along with the turntable, and the first transmission piece and the second transmission piece respectively drive the card feeding mechanism and the card lifting and bearing mechanism to work, so that faults caused by asynchronous operation of the card lifting mechanism and the card lifting and bearing mechanism can be avoided, and only one motor is needed (of course, in order to improve the driving effect, the number of motors for driving the turntable to rotate is increased, but the increased motors belong to unnecessary technical characteristics, which can be known by a person skilled in the art), so that the power output of the card feeding mechanism and the card lifting and bearing mechanism during work can be greatly reduced, and the running cost of the roller-coaster mahjong machine is saved.
The rotating distance of the reciprocating motion of the turntable is determined by the working frequency of the motor, and the working frequency of the motor can be controlled by arranging magnetic control points corresponding to the motors one by one in the mahjong machine. At least eight magnetic control points are required to be arranged in the traditional mahjong machine, the eight magnetic control points respectively control the motor, once one magnetic control point fails, the mahjong machine needs to be maintained, and the magnetic control points need to be checked one by one during maintenance; in the application, only one motor is needed, so that only one magnetic control point is needed (the magnetic control points are arranged in one-to-one correspondence with the motors, so that when the number of the motors is increased in a preferred scheme, the number of the magnetic control points can be correspondingly increased, but a person skilled in the art can understand that the increased magnetic control points also belong to unnecessary technical characteristics), the occurrence of failure rate is greatly reduced, and the magnetic control points are not time-consuming to be checked even if the failure occurs, so that the maintenance is more convenient.
In the roller coaster mahjong machine, the rotary connection mode between the rotary table and the base is as follows: the rotary table is in a circular shape, a first annular folded edge which is bent towards the lower part of the rotary table is arranged at the inner ring of the rotary table, and a second annular folded edge which is bent towards the lower part of the rotary table is arranged at the outer ring of the rotary table;
