The mahjong tiles are named as sparrow tiles (also named as Ma hang) and are called as sparrow tiles for short, and are a game invented by ancient Chinese people. A set of mahjong tiles comprises that "ten thousand, cake and strip" are 3 basic suits, which are called: the card comprises ten thousand cards, cheese cards (cakes) and striped cards (strings), wherein each card comprises 4 cards from one card to nine card, and the total number of the cards is twenty-seven 108 cards; 4 cards of 'east, south, west, north, middle, hair and white' characters are added, and seven cards of 28 cards are counted; the total number of the tiles is 136, and the tile is the 'Suyun mahjong' which we say at ordinary times. Then, the flower cards with the similar function to the king (Jorker) in the poker are added, and the number of the flower cards is generally eight: the total number of the brands of spring, summer, autumn, winter, plum, orchid, bamboo and chrysanthemum is one hundred and forty four, so that the name of the flower and hemp family is formed. And 8 wild cards are additionally arranged. Thus, a complete set of mahjong tiles, 152 (74 in some regions), includes word tiles, flower tiles, ordinal tiles, and wild tiles. The popular mahjong is a simplified mahjong without joker and large white board, and the number of the mahjong is 144. Compared with other domino forms, the playing method of mahjong is the most complex and interesting, the basic playing method is simple and easy to operate, but the change is extremely large, and the matching and combination are different from person to person, so that the mahjong is one of the most attractive playing forms in the history of China.

Along with the continuous improvement of the living standard, people pay more and more attention to leisure and entertainment life, and the convenient and labor-saving automatic mahjong machine is gradually loved by people.

The existing four-opening automatic mahjong machine is limited by the structure of the pushing and lifting mechanism, when the mahjong machine is pushed and lifted to play, two mahjong pieces are stacked together to play, and only one row of mahjong pieces is arranged in front of each person on the table top. For example, patent document CN201164721 discloses a pushing and lifting mechanism of an automatic mahjong machine, which comprises a lattice plate, a mahjong storage plate, and a mahjong supporting device and a mahjong pushing device which are respectively arranged at two sides of the mahjong storage plate, wherein the mahjong supporting device comprises a supporting plate, a supporting plate supporting device and a mahjong supporting cam driven by a motor, a connecting rod is arranged on the mahjong supporting cam, a supporting plate bracket with a waist hole is arranged below the supporting plate, one end of the connecting rod is movably arranged in the waist hole, a sensor is arranged in the middle of the mahjong storage plate, and the pushing and lifting mechanism only has one fixed mahjong storage plate, so that the pushing and lifting mechanism can only push a row of mahjong at each time, and twelve or thirteen mahjong tiles which are opened need to be manually grabbed when the mahjong starts to be played. In order to make up for the deficiencies of the existing four-opening mahjong machine, eight-opening mahjong machines have been developed in the industry, and the eight-opening mahjong machines can also stack twelve or thirteen tiles required for game opening.

a first height, which is the lower deck area 312 of the deck block 31 for storing the first tile in that area; in the first height, the height of the bottom plate lower deck of the lower deck area 312 is slightly lower than the height of the card outlet of the card delivery device 2.

A second height, which is the lower holding area 312 of the holding block 31 for storing a second mahjong tile in the area; in the second height, the top surface of the first mahjong is lower than the card outlet of the card sending device 2, the lower card bearing area 312 bears the second mahjong sent from the card sending channel, and the second mahjong is superposed on the first mahjong;

the third height is that the upper card-holding area 311 of the card-holding block 31 is used for storing the first mahjong card in the area; in the third height, the height of the card holding plate on the bottom plate of the upper card holding area 311 is slightly lower than the height of the card outlet of the card feeding device 2.

Based on the structure of the tile bearing block 31, the tile pushing head needs to be capable of pushing the mahjong tiles in the upper tile bearing area 311 and the lower tile bearing area 312 to the corresponding tile storage grooves respectively, and in the first scheme, two tile pushing heads which operate independently can be used for pushing the mahjong tiles in the upper tile bearing area 311 and the lower tile bearing area 312 respectively. In the second scheme, the mahjong tile pushing device comprises an upper tile pushing head 361 and a lower tile pushing head 362, wherein the upper tile pushing head 361 and the lower tile pushing head 362 are synchronously driven by the same driving structure to respectively push mahjong tiles in an upper tile bearing area 311 and a lower tile bearing area 312. In the third embodiment, a pushing head is adopted, the pushing head comprises an upper pushing area for pushing the mahjong tiles in the upper tile bearing area 311 and a lower pushing area for pushing the mahjong tiles in the lower tile bearing area 312, a gap is arranged in the upper pushing area and the lower pushing area and corresponds to the bottom plate of the upper tile bearing area 311, so that the pushing head is not obstructed by the tile bearing block 31 when pushing the mahjong tiles. In the embodiment shown in particular in figures 2 and 3, the push-up shoe 361 and the push-down shoe 362 are driven synchronously by the same drive structure. Specifically, the stacking and pushing device 3 further includes a tile pushing slider 37 laterally sliding and limited on the housing 32, specifically, a laterally arranged optical axis is arranged on the housing 32, the tile pushing slider 37 is slidably arranged on the optical axis, and the tile pushing slider 37 is connected with the upper tile pushing head 361 and the lower tile pushing head 362 to realize synchronous lateral sliding. The card holding cam 34 drives the card pushing slider 37 to slide transversely, so that the card pushing actions of the upper card pushing head 361 and the lower card pushing head 362 are controlled to be linked with the lifting motion of the card holding block 31. In the embodiment shown in the figure, a card pushing curve slot 371 is arranged on the card pushing slide block 37, a card pushing roller 342 is arranged on the card bearing cam 34, the card pushing roller 342 moves in the card pushing curve slot 371, and the card pushing slide block 37 is changed in the transverse direction based on the change of the moving position of the card pushing roller 342 in the card pushing curve slot 371.

In the above solution, the position of the tile bearing roller 352 in the tile bearing curved groove 341 changes, so that the tile bearing block 31 is lifted; the position of the card-pushing roller 342 in the card-pushing curved groove 371 changes, so that the card-pushing slider 37 moves in the lateral direction. Therefore, the curve variation of the card holding curved slot 341 and the card pushing curved slot 371 affects the card holding block 31 (stacking action) and the card pushing slider 37 (card pushing action). Specifically, the shapes of the card holding curved groove 341 and the card pushing curved groove 371 may refer to the shapes of the card holding curved groove and the card pushing curved groove described in the chinese patent publication No. CN107335216A, but those skilled in the art may also make adaptive changes to the card holding curved groove and the card pushing curved groove as needed.

The stacking and pushing device 3 completes the stacking of the three mahjong tiles and divides the three mahjong tiles into two groups; the upper group is a single mahjong tile, and the lower group is a stack of two mahjong tiles. In the subsequent slope card-playing device, the card-feeding support comprises two card-storing grooves (a first card-storing groove 41 and a second card-storing groove 42) and two card-lifting supports (a first card-lifting support 43 and a second card-lifting support 44); there are also two sets of card raising assemblies (a first card raising assembly and a second card raising assembly). Specifically, the starting ends of the first card storage groove 41 and the second card storage groove 42 respectively receive the card outlet end of the stacking and pushing device 3, and the first card storage groove 41 is located below the second card storage groove 42. The first card storage groove 41 is used for receiving two layers of stacked mahjong tiles sent out from the lower card bearing area 312, and the second card storage groove 42 is used for receiving a single layer of mahjong tiles sent out from the upper card bearing area 311.

In the slope mahjong tile discharging device, two groups of mahjong tile feeding assemblies can be selected to be respectively used for pushing mahjong tiles on the first mahjong tile storage groove 41 and mahjong tiles on the second mahjong tile storage groove 42, each group of mahjong tile feeding assembly comprises a mahjong tile feeding swing rod and a mahjong tile feeding motor, the mahjong tile feeding motor drives the mahjong tile feeding swing rod to rotate along one end of the mahjong tile feeding swing rod, the other end of the mahjong tile feeding swing rod slightly passes through the mahjong tile storage groove to achieve the purpose of pushing the mahjong tiles, and on one hand, two groups of driving motors are arranged for driving the mahjong tile feeding assemblies to respectively push the mahjong tiles, so that the structure is complex, and the cost is high; on the other hand, whether the swing paths of the two mahjong loading swing rods are staggered or are matched with the mahjong loading bracket and the mahjong storage groove or not is also considered. In addition, refer to the technical solution described in publication No. CN108096828A, a card pulling assembly is respectively disposed in the first card storage slot 41 and the second card storage slot 42, the card pulling assembly includes a card pulling head moving along the track direction of the first card storage slot 41 or the second card storage slot 42, and the card pulling head may be driven by a card pulling motor through a wire rope or a belt as in the patent document with publication No. CN 108096828A. Of course, the two schemes can be combined, namely, the mahjong loading swing rod is adopted when the first mahjong storage groove 41 pushes the mahjong, and the mahjong pulling head is adopted when the second mahjong storage groove 42 pushes the mahjong; or the opposite of the two schemes described above.

In the embodiment shown in the figure, the slope card-playing device adopts the same card-playing assembly, the card-playing assembly comprises a first card-playing swing rod, a second card-playing swing rod and a card-playing motor, and the first card-playing swing rod and the second card-playing swing rod are coaxially and rotatably arranged and are driven by the card-playing motor. As mentioned above, the first card storage slot 41 is located below the second card storage slot 42, and a gap is left between the top of the first card storage slot 41 and the bottom of the second card storage slot 42, so that the first card feeding swing rod extends into the first card storage slot 41 to push cards. The track path of the first mahjong tile storage groove 41 is in a C shape, and the first mahjong tile storage groove 41 is in a circular arc shape taking the rotating axis of the first mahjong tile feeding swing rod as the center of circle; the track path of the second mahjong tile storage groove 42 is J-shaped, the J-shaped mahjong tile storage groove comprises an arc-shaped section 421 and a straight-line section 422, the arc-shaped section 421 is located in front of the straight-line section 422, namely the head end of the straight-line section 422 is connected with the tail end of the arc-shaped section 421, the arc-shaped section 421 coincides with the radian of the first mahjong tile storage groove 41, and the straight-line section 422 is attached to the edge of the mahjong machine frame 1, and the second mahjong tile lifting supporting plate 46 and the second mahjong tile lifting port are located on the same straight line. When the mahjong loading motor drives the first mahjong loading swing rod and the second mahjong loading swing rod to rotate, the first mahjong loading swing rod pushes mahjong tiles to the first mahjong lifting supporting plate 45 along the track of the first mahjong storage groove 41, and the first mahjong lifting supporting plate 45 lifts to the desktop after lifting; the second mahjong loading swing rod pushes the mahjong tiles to the second mahjong lifting supporting plate 46 along the track of the second mahjong storage groove 42, and the second mahjong lifting supporting plate 46 lifts the mahjong tiles to the desktop after being lifted. In the above solution, in order to push the mahjong tiles to the second tile lifting supporting plate 46 completely by the second tile feeding swing rod, the movable end of the second tile feeding swing rod needs to pass through the end of the straight section 422 of the second tile storage slot 42, so as to ensure that no mahjong tiles remain in the second tile storage slot 42 after the second tile feeding swing rod passes through. In addition, in the above scheme, it is indicated that the first card storage slot 41 is located below the second card storage slot 42, the second card storage slot 42 is located above, at this time, the relative position of the second card storage slot 42 is higher, the swing angle of the second card lifting support plate 46 is smaller, and as the swing angle is smaller, too much space for avoiding is not needed to be made in the inside of the rack 1; the rail mahjong splitting device disclosed in the patent document of the chinese utility model with the publication number "CN 208694238U", in the scheme, the rail mahjong splitting device comprises a first rail for sequentially conveying mahjong pieces to be grabbed separated from the main rail to the mahjong tile grabbing area, a second rail for sequentially conveying the mahjong pieces to be played separated from the main rail to the mahjong tile playing area, and a mahjong tile pushing mechanism for pushing the mahjong tiles. In the scheme, the conveying track of mahjong tiles to be played is positioned below the mahjong tile lifting mechanism, so that a second sub-track and the mahjong tile pushing mechanism are required to be arranged, and a larger avoiding space is made to realize the lifting of the mahjong tile lifting supporting plate in a larger angle. In addition, in the scheme, because the inclination angle of the second tile lifting supporting plate 46 when receiving the mahjong tiles is relatively small, the mahjong tiles cannot slide down due to too large inclination angle in the lifting process of the second tile lifting supporting plate 46. In another embodiment with the same effect, the card feeding assembly comprises a card feeding swing rod 47 and a card feeding motor for driving the card feeding swing, and a card feeding pushing head connected to the movable end of the card feeding swing rod 47, wherein the card feeding pushing head comprises a first card feeding part and a second card feeding part, the first card feeding part pushes the mahjong tiles to the first card lifting supporting plate 45 along the track of the first card storage groove 41, the second card feeding part pushes the mahjong tiles to the second card lifting supporting plate 46 along the track of the second card storage groove 42, and the second card feeding part passes through the tail end of the straight line segment 422 of the second card storage groove 42. The scheme is that the first mahjong loading swing rod and the second mahjong loading swing rod which are coaxially and rotatably arranged in the scheme are combined into one mahjong loading swing rod 47, and two mahjong loading parts are arranged to meet the mahjong loading requirements of the first mahjong storage groove 41 and the second mahjong storage groove 42.

Similarly, in the automatic mahjong machine, four groups of picking and carrying systems are respectively arranged at four sides of the shuffling tray, mahjong tiles sent out from the first tile storage groove 41 of each group of picking and carrying systems are in front of the player at the side, and mahjong tiles sent out from the second tile storage groove 42 of each group of picking and carrying systems are in front of the player at the downstream side.

The main innovation points of the mahjong machine are as follows: under the action of an eight-port machine of the existing three-layer mahjong machine, the mahjong conveying device 2 of the mahjong machine is divided into an upper mahjong bearing area 311 and a lower mahjong bearing area 312, and a first mahjong storage groove 41 and a second mahjong storage groove 42 are adopted in a slope mahjong conveying device corresponding to the mahjong conveying device, the first mahjong storage groove 41 receives two-layer stacked mahjong conveyed from the lower mahjong bearing area 312, and the second mahjong storage groove 42 receives a single-layer mahjong conveyed from the upper mahjong bearing area 311; in order to simplify the card feeding structure, the second card storage groove 42 is arranged above the first card storage groove 41, so that the swing angle of the second card lifting supporting plate 46 is small, the inclination angle in carrying is small, and too much avoidance space is needed; the card lifting can be realized by adopting a single card feeding assembly; the structure is simplified, and the efficiency is improved.

The arranging method of the mahjong tiles of the mahjong machine comprises the following steps:

when the mahjong machine works, the shuffling large disc rotates and the mahjong tile scraping device is not moved, mahjong tiles on the shuffling large disc are respectively pushed to the lower part of the tile inlet of the four tile conveying devices 2 at the edge of the shuffling large disc, the mahjong tiles are sucked by the tile sucking wheels in the tile conveying devices 2 and are conveyed to the tile conveying channels in the same direction, then the mahjong tiles are conveyed to the tile bearing block 31 in the stacking and pushing device 3 from the tile outlet of the tile conveying channels through the conveying belt, one mahjong tile in three mahjong tiles continuously conveyed out from the tile conveying devices 2 is pushed to the upper tile bearing area 311 of the tile bearing block 31, the other two mahjong tiles are pushed to the lower tile bearing area 312 of the tile bearing block 31 and are stacked into a pier, the tile bearing sequence of the upper tile bearing area 311 and the lower tile bearing area 312 can be adjusted according to requirements, and the adjustment scheme is in the matching action process of the tile bearing cam 34 and the tile pushing slide block 37; then, the upper pushing head 361 of the stacking and pushing device 3 pushes the mahjong tiles in the upper tile bearing area 311 into the second tile storage groove 42, and the lower pushing head 362 pushes the mahjong tiles in the lower tile bearing area 312 into the first tile storage groove 41; repeating the stacking and pushing steps, and waiting for a card-loading signal when enough mahjong tiles are stored in the first card storage slot 41 and the second card storage slot 42. After receiving the card-feeding signal, the movable end of the first card-raising supporting plate 45 descends to be connected with the tail end part of the track of the first card-storing groove 41, and the movable end of the second card-raising supporting plate 46 descends to be connected with the tail end part of the track of the second card-storing groove 42; the mahjong loading motor drives the first mahjong loading swing rod and the second mahjong loading swing rod to synchronously rotate, the first mahjong loading swing rod pushes mahjong tiles to the first mahjong lifting supporting plate 45 along the track of the first mahjong storage groove 41, and the second mahjong loading swing rod pushes the mahjong tiles to the second mahjong lifting supporting plate 46 along the track of the second mahjong storage groove 42; after the mahjong is loaded, the first mahjong lifting supporting plate 45 and the second mahjong lifting supporting plate 46 are lifted, and then the mahjong is lifted to the table top plate.

Based on the arrangement method of the mahjong tiles, the desktop plate is provided with four first tile lifting ports and four second tile lifting ports, so the mahjong tile arranging machine is called an eight-port machine; the mahjong tiles sent to the tabletop plate by the first mahjong lifting supporting plate 45 are mahjong tiles required by card drawing, and the two layers are stacked; the mahjong tiles sent to the table top by the first tile raising supporting plate 45 are cards which are issued to each player in a single-layer manner.

Example 2:

the embodiment also relates to a mahjong machine, as shown in fig. 11 to 13, the mahjong machine comprises a central control panel assembly 11 located in the center of the bottom plate of the machine frame 1, a shuffling large plate and a mahjong scraping device, four groups of mahjong picking and carrying systems are arranged around the shuffling large plate, each mahjong picking and carrying system comprises a mahjong feeding device 2 used for picking and feeding mahjong tiles from the shuffling large plate one by one, a stacking device used for stacking a plurality of mahjong tiles into one pier and pushing the mahjong tiles into a mahjong storage groove, and a slope mahjong discharging device used for feeding the stacked mahjong tiles onto the table surface of the mahjong machine along a slope.

Namely, four first mahjong lifting ports 13 for sending mahjong required by card drawing and four second mahjong lifting ports 14 for sending mahjong required by card opening and dealing are arranged on a table top plate 12 of the machine frame 1. The four first tile lifting ports 13 are located in the middle of the table top 12 and are disposed around the central control panel assembly 11. The first tile lifting port 13 is similar to the tile lifting position of a four-port machine adopted at present, the first tile lifting port 13 in the scheme is obliquely arranged relative to the edge of a table top, and the distance between the left side end of the first tile lifting port 13 and the edge of the table top is smaller than the distance between the right side end of the first tile lifting port 13 and the edge of the table top, so that the left end and the right end are judged in the direction of a user at the side; therefore, the operation space of the right front space of the user is larger, and the device is suitable for handedness of most users. The four second tile lifting ports 14 are respectively positioned at the four end edges of the table top plate 12 and are substantially parallel to the edges of the table top; after the second tile lifting port 14 delivers the mahjong tiles, the user only needs to lift the mahjong tiles at the position, which is equivalent to the step of manually dealing the mahjong tiles in the traditional four-port machine.

The card feeding device 2 in this embodiment is similar to that used in embodiment 1, and patent documents with publication numbers CN105413161A, CN106492454A, and CN106669142A can be referred to.

The difference is that in the embodiment, the upper tile receiving area 311 of the stacking and pushing device 3 is used for receiving two-layer stacked mahjong tiles, and the lower tile receiving area 312 is used for receiving a single-layer mahjong tile. Therefore, the first mahjong tile storage groove 41 for receiving two-layer stacked mahjong tiles is positioned above the second mahjong tile storage groove 42 for receiving single-layer mahjong tiles. In this embodiment, the card feeding assembly specifically includes a first card feeding assembly and a second card feeding assembly. Wherein, the first mahjong tile feeding assembly pushes the two layers of stacked mahjong tiles in the first mahjong tile storage groove 41 to the first mahjong tile lifting port 13 along the inclined plane; the second card feeding assembly pushes the single-deck tiles in the second storage slot 42 along the incline to the second card lifting port 14. That is, in this embodiment, cards are dealt in the first card-raising gate 13 and the second card-raising gate 14 in a manner of raising cards on a slope.

In one specific embodiment, referring to fig. 1 of the drawings of example 1, the first card storage slot 41 and the second card storage slot 42 are arranged in a direction from the beginning to the end in a counterclockwise direction along the shuffler board, the beginning and the end of the first card storage slot 41 are located in front of the same player, and the end of the second card storage slot 42 is located in front of the player located counterclockwise downstream of the beginning thereof. Specifically, as shown in the figure, the track path of the first card storage groove 41 is a circular ring shape with the rotation axis of the first card feeding assembly as the center, and the arc center angle formed by the path of the first card storage groove 41 is greater than or equal to 180 °. By adopting the scheme, the first mahjong storage groove 41 conveys mahjong tiles along the anticlockwise direction of the shuffling large plate, in order to enable the starting end and the tail end of the first mahjong storage groove 41 to be positioned in front of players on the same side, the first mahjong storage groove 41 needs to turn by more than or equal to 180 degrees, and then the circular arc-shaped first mahjong storage groove 41 can be used for feeding mahjong tiles in a swing rod pushing mode. In a specific scheme, the first mahjong loading assembly comprises a mahjong loading motor and a mahjong loading swing rod, wherein one end of the mahjong loading swing rod is connected to the output end of the mahjong loading motor; the movable end of the mahjong loading swing rod pushes mahjong tiles along the track of the first mahjong storage groove 41. In addition, the two-layer piled mahjong tiles in the first tile storage groove 41 are pushed to the first tile lifting port 13 along the inclined plane in the scheme, so the slope tile playing device further comprises a tile lifting assembly, the end part of the first tile storage groove 41 is connected with a first tile lifting support 43, the specific structure of the tile lifting assembly can refer to the tile lifting structure in the Chinese utility model patent application with the application number of '2019200586016' filed by the applicant in the day, and the tile lifting structure comprises a first tile lifting supporting plate 45 with one end hinged to the first tile lifting support 43 and a tile lifting driving assembly for driving the first tile lifting supporting plate 45 to move along the hinged end of the first tile lifting supporting plate 45.

In another specific embodiment, referring to fig. 12 and 13, the first card storage groove 41 and the second card storage groove 42 are arranged along the direction of the card shuffling large disc clockwise from the beginning to the end; the end portions of the first card storage groove 41 and the second card storage groove 42 are located on the front side of the player in the clockwise direction of the starting end thereof. In the embodiment shown in the drawings, the track path of the first card storage groove 41 is in a shape of "J", and the first card storage groove 41 comprises a starting section attached to the edge of the rack 1 and an arc section turning from the end of the starting section to the lower part of the first card lifting port 13 in the middle of the mahjong machine. Since the first card storage slot 41 and the second card storage slot 42 in this embodiment both adopt a J shape, not a circular arc structure, the first card feeding assembly cannot use the swing link pushing manner in the above-mentioned embodiment. In this embodiment, the first card feeding assembly includes a first card feeding pushing block 481 and a first traction assembly for driving the first card feeding pushing block 481 to move back and forth along the first card storage slot 41. The first traction assembly is a traction pull rope 482 arranged along the track direction of the first mahjong storage groove 41, specifically, a synchronous belt, a steel wire rope or a chain can be adopted, and specific embodiments can be seen in patent documents with publication numbers CN201783185U which disclose a chain-driven slope mahjong tile discharging device for a full-automatic mahjong machine; or the automatic mahjong machine disclosed in patent documents with publication numbers CN103861280A and CN104645608A, which discloses a scheme for realizing the mahjong tile feeding by driving the pushing head of the mahjong tile to move by using a steel wire rope. Similarly, in the present embodiment, the first card storage slot 41 is connected to the end portion thereof with a first card lifting support 43, and the specific structure of the card lifting assembly can be referred to the card lifting structure in the chinese utility model patent application with application number "2019200586016" filed by the applicant in the day, and the card lifting assembly includes a first card lifting support plate 45 with one end hinged to the first card lifting support 43, and a card lifting driving assembly for driving the first card lifting support plate 45 to move along the hinged end thereof. The first card raising supporting plate 45 can swing in a certain range relative to the first card raising bracket 43 along the hinged end of the first card raising supporting plate, and when the movable end of the first card raising supporting plate 45 is positioned at the lowest end of the swing path, the first card raising supporting plate 45 is connected with the tail end part of the track of the first card storage groove 41; when the movable end of the first card raising support plate 45 is positioned at the uppermost end of the swing path, the first card raising support plate 45 is positioned horizontally and closes the first card raising port 13.

Based on the layout structure of the first card storage slot 41 and the specific structure of the first card feeding assembly adopted by the first card storage slot 41 in the above two schemes, the present embodiment is different from the prior art in that the second card storage slot 42 adopts a passive card feeding scheme. The scheme adopted in embodiment 1 is that the swing link pushes the mahjong tiles in the first tile storage groove 41 and the second tile storage groove 42 at the same time. As shown in fig. 1 of embodiment 1 and fig. 12 of this embodiment, the second card storage groove 42 is J-shaped, except that the second card storage groove 42 is fed clockwise or counterclockwise along the shuffling platter. However, the second card storage slot 42 is applicable to the following embodiment, in a specific embodiment, a card lifting inclined plane is provided at the end of the second card storage slot 42 to connect with the second card lifting port 14, unlike example 1, the card lifting inclined plane 491 in this embodiment is fixedly connected to the end of the first card storage slot 41, and the second card lifting support plate in example 1 is in a slope manner with one end hinged and the other end capable of lifting. In this embodiment, since the tile lifting slope 491 is fixed, it does not have the function of lifting the mahjong tiles, and the mahjong tiles need to be forcibly pushed onto the tile lifting slope 491 by the second tile lifting assembly and then be delivered to the table top 12 through the second tile lifting opening 14. In view of the above-mentioned use cases, the passive tile feeding method is generally used as a single-layer tile discharging structure for the mahjong tiles, because the double-layer mahjong tiles are easy to slide and shift when pushed on the inclined surface. Meanwhile, the slope of the tile lifting slope 491 should also be considered, too small slope will make the tile lifting slope 491 longer and occupy the space of the mahjong machine, too large slope will make it difficult to push the mahjong tiles onto the table top plate 12; the angle shown in the drawings of this embodiment is 36 °, but it should be adjusted by those skilled in the art within a suitable angle as needed. In addition, in order to make it easier to push the mahjong tiles onto the table top 12 through the tile lifting slope 491, the second tile storage slot 42 can be gradually lifted along the feeding direction. In a specific embodiment, the second card feeding assembly comprises a card feeding pushing assembly and a second traction assembly for driving the card feeding pushing assembly to move along the track direction of the second card storage slot 42; the card feeding pushing assembly is longitudinally adjustable relative to the depth of the second card storage slot 42. The second traction assembly is arranged along the track direction of the second mahjong storage groove 42, is consistent with the first traction assembly, and can adopt a synchronous belt or a steel wire rope or a chain, and the specific implementation scheme can be respectively referred to the patent document with the publication number of CN201783185U to disclose a chain-driven slope mahjong tile discharging device for the full-automatic mahjong machine; or the automatic mahjong machine disclosed in patent documents with publication numbers CN103861280A and CN104645608A, which discloses a scheme for realizing the mahjong tile feeding by driving the pushing head of the mahjong tile to move by using a steel wire rope. In the drawings of this embodiment, the second traction assembly is a chain 401, which can be driven by a driving motor through a gear. As shown in the figures, the card feeding pushing assembly comprises a sliding column 402, a card feeding pushing block 403 and a sliding seat 404; the sliding column 402 is arranged on the second card storage groove 42 in a penetrating manner in the depth direction of the second traction assembly, the card feeding push block 403 is connected to the sliding column 402 above the second traction assembly, and the sliding seat 404 is connected to the sliding column 402 below the second traction assembly; the sliding column 402 can move along the axial direction relative to the second traction assembly, and a spring 405 is arranged between the second traction assembly and the sliding column 402 between the sliding seats 404; a sliding track which is matched with the sliding seat 404 and adjusts the height of the sliding seat 404 is arranged below the second mahjong tile storage groove 42. In the embodiment shown in fig. 14, a linear through hole 423 is formed in the middle of the bottom of the second card storage slot 42 along the track direction, the card feeding pushing block 403 extends out of the linear through hole 423, and the sliding column 402, the spring 405 and the sliding seat 404 below the card feeding pushing block 403 are all located below the second card storage slot 42. The sliding track may be completely consistent with the track direction of the second card storage groove 42, or may be completely consistent with the second card storage groove 42 only in the height adjusting section of the card storage groove. The sliding seat 404 may be a smooth fit with the sliding rail, or a rolling fit, for example, rollers may be installed on the sliding seat 404, or balls may be installed on the sliding rail. The mahjong tile feeding pushing assembly moves to push mahjong tiles, a driving motor in the second traction assembly drives a chain 401 to convey along the rail direction of the second tile storage groove 42 through a gear to drive the mahjong tile feeding pushing assembly to move along the linear through hole 423, and a mahjong tile feeding pushing block 403 in the mahjong tile feeding pushing assembly extends into the second tile storage groove 42 to push mahjong tiles. The front mahjong tiles are smoothly pushed out of the second tile lifting port 14 along the tile lifting inclined plane 491 in a stacking and pushing mode, and when the tile pushing block 403 moves to the position of the tile lifting inclined plane 491, the last mahjong tiles are smoothly pushed out of the second tile lifting port 14; at this time, the sliding seat 404 is matched with the sliding rail, the sliding seat 404, the sliding column 402 and the mahjong tile pushing block 403 connected with the sliding seat are lifted by the height of the sliding rail, the spring 405 is compressed, and the mahjong tile pushing block 403 is lifted to push the last mahjong tiles out of the second mahjong tile lifting port 14. When the second traction assembly drives the card-loading pushing assembly to return along the track of the second card storage slot 42, the sliding track is lowered in height, and the card-loading pushing block 403 is lowered in height under the action of gravity and the force of the spring 405.
