Example

[0036] A tile-pushing device for a mahjong machine includes a tile-receiving block 3 for receiving mahjong tiles delivered by a tile-feeding device and a tile-pushing head 4 for pushing mahjong tiles off the tile-receiving block 3. It also includes a tile-pushing transmission mechanism for driving the tile-receiving block 3 to move up and down and the tile-pushing head 4 to swing horizontally back and forth around a specific axis. The tile-pushing transmission mechanism includes a tile-pushing wheel 22 and a transmission shaft 25.

[0037] The push-tile wheel 22 is rotatably mounted on the outer casing. A stacking curve groove 23 is provided on one end face of the push-tile wheel 22. One end of the stacking swing rod 35 is hinged to the outer casing and is movably connected to the stacking curve groove 23 on the push-tile wheel 22. The other end of the stacking swing rod 35 is connected to the tile-bearing block 3. When the push-tile wheel 22 rotates, it can drive the stacking swing rod 35 to move up and down through the stacking curve groove 23, so that the tile-bearing block 3 can complete the stacking and lifting of mahjong tiles.
