after the guests order dishes, the CPU (84) stores the order of the guests ordering dishes, a chef is used for frying dishes from the data stored by the CPU (84) and observing the data through the display screen (81), the dishes are placed in the placement box (35) after the dishes are fried, and the cross section of the placement box (34) and the cross section of the curled edge (35) are of a straw hat-shaped structure, so that the dishes are placed in the placement box (34) more stably, the splashing of the dishes is avoided, the inner part of the placement box (34) is fixedly connected with a rubber skin (38) in a hemispherical structure, the surface of the rubber skin (38) is provided with protrusions (37) at equal intervals, on one hand, the dishes are supported, on the other hand, the dishes are prevented from being splashed due to shaking during distribution, grooves (36) are symmetrically formed in the top of the curled edge (35) which is obliquely arranged, and the dishes are convenient to take;

the triangular connecting frame (31) is rotationally connected to the surface of the connecting plate (5) through the rotating shaft (33), different or same dishes are placed in the storage box (34) at a constant speed and cannot fall off because the connecting plate (5) is fixed on the surface of the driving shaft (61) at equal intervals, the whole structure is matched with the display screen through the camera (21) to walk in a restaurant, a guest observes the inside of the barrel (7) through the observation window (22) to push a first button (82) to realize that the first motor (11) is not moved, a second button (83) is pushed to realize that the second motor (63) is not moved to facilitate the guest to take the dishes, the dustproof plate (42) is opened to take the foods from the taking port (43), the dustproof plate is closed after the taking is completed, and the first button (82) is pushed again to realize that the first motor (11) drives to send the dishes again;

the surface of drive shaft (61) is annular array form fixed connection relatively set up connecting plate (5), be link (31) that triangle-shaped structure is connected to the side through pivot (33) rotation between arbitrary two connecting plates (5), on the one hand, the dish is put the volume, on the other hand, fixed connection is rectangle structure hold board (32) between two link (31), hold the bottom of board (32) be equipped with turn-up (35) fixed connection place box (34), and place the cross-section of box (34) and turn-up (35) and be straw hat nature structure, make the dish put in place the inside of box (34) more stable, avoid the dish to spill, the inside fixed connection of placing box (34) is rubber (38) of hemisphere structure, the surface equidistance of rubber (38) is equipped with arch (37), on the one hand has supported the dinner plate, on the other hand avoided the dish to shake when the delivery and has led to splash dish, the top symmetry of turn-up (35) that the slope set up sets up is recess (36), the dustproof board (42) that arc mechanism is the side is to the inside slip connection of turn-up of barrel (7), will be the dustproof board (42) when the delivery is closed, the dust-proof board is closed when the delivery, the dust-proof board is closed of the food of the person (42) is avoided falling down to the food protection of the person and has been confirmed to have good dust-proof property.
