The traditional structure forms of stacking and lifting the mahjong pieces cause the high manufacturing cost, large occupied space, high use failure rate, difficult maintenance and poor adaptability of the whole mahjong machine. In addition, the existing tile lifting mechanism only lifts the mahjong tiles stacked by the tile stacking mechanism to the edge position of the upper part of the table top of the mahjong machine, and when a player needs to grasp and supplement the mahjong tiles on the edge of the table top of the opposite mahjong machine in the game process, the player often needs to lift up to get up due to a longer grasping distance, so that the physical strength of the player is seriously consumed. Therefore, after the mahjong tiles are lifted onto the table top of the mahjong machine by the tile lifting mechanism and before the game starts, each player needs to push the mahjong tiles in front of himself to the middle of the table top of the mahjong machine so as to facilitate grabbing to the player; this not only affects the consistency of the game progress, but also the game experience and comfort are poor. Therefore, the four-port full-automatic mahjong machine in the prior art needs to be improved.

The side part of the flip arc rack 58 is slidably arranged in the arc guide groove 56 at the upper part of the transmission connecting frame 36, and the upper end of the flip arc rack 58 is connected with the arc tooth connecting lug plate 57 arranged at the end part of the card pushing flip cover plate 37 through the cover plate connecting lug 59. So as to drive the flip arc-shaped rack 58 to rotate reciprocally along the arc-shaped guide groove 56 by the forward and backward rotation of the flip rotating gear 55 along with the transmission long shaft 34, and further drive the card pushing flip cover plate 37 to open or close.
When the tile lifting and pushing device of the mahjong machine is used, firstly, the contact rotary posts 21 of the driven tile lifting gear I15 and the driven tile lifting gear II 18 are respectively positioned at the first descending driving sections 26 of the driving bayonets 25 at the two sides of the lower part of the tile lifting driving frame 12, namely the tile lifting driving frame 12 is positioned at the initial position for placing the first layer of mahjong tiles; then, the mahjong pieces sucked randomly from the shuffling cavity are sequentially conveyed to the tile supporting frame 3 at the upper part of the tile lifting driving frame 12 by the tile feeding mechanism in the mahjong machine core and corresponding to the tile lifting front pushing device. After the number of the first layer of mahjong tiles on the tile supporting frame 3 meets the requirement, the driving motor 6 drives the driving motor gear 16 to rotate so as to drive the contact rotary column 21 on the driven tile lifting gear I15 and the driven tile lifting gear II 18 to rotate towards the second descending driving section 27 of the driving bayonet 25, and then the tile supporting frame 3 at the upper part of the tile lifting driving frame 12 is driven to move downwards by one mahjong tile thickness; then, the mahjong tiles sucked randomly from the shuffling cavity are sequentially conveyed to the upper part of one layer of mahjong tiles arranged on the tile supporting frame 3 by the tile feeding mechanism, so that a mahjong tile pile (shown in figure 1) which is formed on the tile supporting frame 3 in a two-layer stacked mode is formed.
Subsequently, the driving motor 6 continuously drives the driving motor gear 16 to rotate, so that the contact rotary column 21 on the driven card lifting gear I15 and the driven card lifting gear II 18 passes through the stable cover opening contact section 28 of the driving bayonet 25, and the position of the card lifting driving frame 12 is temporarily kept still; simultaneously, the cover plate of the annular inner groove of the tile pushing rotary cam 8 which rotates along with the driven tile lifting gear II 18 opens the inner groove section 44, the tile pushing swing arm 9 is driven to swing upwards around the swing arm pivot 10 through the cam linkage post 40, the tile pushing driving rack 11 is driven to move upwards along the rack guide chute 49 of the rack guide connecting body 33, and the turning cover rotating gears 55 at two ends of the driving long shaft 34 are driven to rotate forwards through the tile pushing driving gear 32 meshed with the tile pushing driving rack 11, so that the tile pushing turning cover plate 37 is opened (as shown in fig. 18 and 19), namely the tile lifting opening exposing the edge position of the upper part of the mahjong table surface.
After the tile pushing overturning cover plate 37 is opened, the driving motor gear 16 which continuously rotates along with the driving motor 6 drives the contact rotary column 21 on the driven tile lifting gear I15 and the driven tile lifting gear II 18 to pass through the lifting driving section 29 of the driving bayonet 25, so that the tile lifting driving frame 12 and the tile pile thereon are driven to move upwards, and the mahjong tile 5 is pushed to the upper part of the table top through the tile lifting opening at the upper edge of the table top of the mahjong machine (as shown in fig. 20 and 21). In this process, the upper position of the annular inner groove of the tile pushing rotary cam 8 which rotates along with the driven tile lifting gear ii 18 maintains the inner groove section 45, and maintains the upper swing position of the tile pushing swing arm 9, that is, the tile pushing driving rack 11 is kept at the upper position and is temporarily stationary (the tile pushing turnover cover plate 37 is in an opened state, so that smooth pushing of the tile pile is facilitated).
After the mahjong pieces are lifted above the table top of the mahjong machine, the driven tile lifting gear II 18 continuously drives the tile pushing rotary cam 8 to rotate, the cover plate of the annular inner groove of the tile pushing rotary cam 8 closes the inner groove section 46, the tile pushing swinging arm 9 is driven to swing downwards around the swinging arm pivot 10 through the cam linkage post 40 so as to drive the tile pushing driving rack 11 to move downwards, and the turning cover plate 37 is gradually closed through reverse rotation of the turning cover plate rotary gears 55 at the two ends of the driving long shaft 34 driven by the tile pushing driving gear 32 (as shown in fig. 22 and 23). In the process of closing the tile pushing and turning cover plate 37, the contact rotary column 21 on the driven tile lifting gear I15 and the driven tile lifting gear II 18 passes through the stable tile pushing contact section 30 of the driving bayonet 25, so that the rising state of the tile lifting driving frame 12 is maintained, and the tile pushing and turning cover plate 37 is convenient for pushing the rising mahjong tile stack. In the process of closing the tile pushing and turning cover plate 37, the tile pushing and turning cover plate 37 is close to the edge of the cover plate on one side of the mahjong tile 5, and the mahjong tile stack on the raised tile supporting frame 3 and above the table top of the mahjong machine can be pushed out for a certain distance to the middle part of the table top. When the tile pushing and turning cover plate 37 is completely closed, the contact rotary column 21 on the driven tile lifting gear I15 and the driven tile lifting gear II 18 which rotate along with the driving motor gear 16 passes through the first descending driving section 26 of the driving bayonet 25, so that the tile lifting driving frame 12 is driven to move downwards to an initial position for placing the first layer of mahjong tiles; prepare for the next "lift card, push forward" action cycle.
