[0024] As a preferred embodiment, as Figure 2 , the above-mentioned weighing rice bin 1 includes an electronic scale base 11 and a bin body 12 provided on the electronic scale base 11. The weight of the rice grains in the bin body 12 can be monitored in real time through the electronic scale, facilitating timely rice addition. The bin body 12 is inclined so that the rice grains at the bottom of the bin body 12 can accumulate together for easy conveying.

[0025] In some embodiments of the present application, as Figure 2The rice steaming body 3 comprises a frame 31, a rice steaming tank 32, a steam conveying assembly 33 and a water material conveying assembly 34. The frame 31 is connected by a steel frame. The frame 31 is closed by setting a plate body around it, and the plate body can be set to an open and close type to facilitate the maintenance of the internal equipment; a support plate can be set in the middle of the frame 31 to support the rice steaming tank 32 and other structures. The rice steaming tank 32 is in the shape of a drum, and the two end surfaces of the rice steaming tank 32 are respectively rotatably mounted on the frame 31 through bearings, so that the rice steaming tank 32 can rotate inside the frame 31 to realize rotary rice steaming. One end surface of the rice steaming tank 32 is connected to the rice grain conveying mechanism 2 and driven to rotate by the first driving mechanism 36; the rice grain conveying mechanism 2 delivers the rice grains into the rice steaming tank 32, and the first driving mechanism 36 can drive the rice steaming tank 32 to realize 360-degree rotary rice steaming, so as to improve the uniformity of heating of the rice grains and avoid agglomeration, thereby improving the taste of the rice.

[0026] As a preferred implementation method, Figure 2 and Figure 3 The rice grain conveying mechanism 2 includes a spiral rice feeding tube 21, a rice rotating motor 22, a rice feeding tube 23, a spiral rice feeding tube 24, a rice feeding motor 25, and a push rod assembly 28; the spiral rice feeding tube 21 is penetrated into the weighing rice bin 1 and one end of the spiral rice feeding tube 21 is transmission-connected to the rice rotating motor 22, and the other end of the spiral rice feeding tube 21 is connected to the rice feeding tube 23; it should be noted that the spiral rice feeding tube 21 is composed of a tube body and a propeller arranged inside the tube body, and the internal propeller is connected to the rice rotating motor 22, and the rice grains are conveyed by the rotation of the propeller in the spiral rice feeding tube 21, and the rice grains are conveyed to the rice feeding tube 23.

[0027] The other end of the rice feeding pipe 23 is communicated with the side wall of the spiral rice feeding pipe 24, and the rice grains are fed into the spiral rice feeding pipe 24. One end of the spiral rice feeding pipe 24 penetrates into the rice steaming tank 32 from the end face center of the rice steaming tank 32, and the other end of the spiral rice feeding pipe 24 is connected to the rice feeding motor 25. It should be noted that the spiral rice feeding pipe 24 has the same structure as the spiral rice feeding pipe 21, and both have a motor to drive the internal propeller to rotate to realize rice feeding. The propeller of the spiral rice feeding pipe 24 is driven to rotate by the rice feeding motor 25, so that the rice grains are horizontally fed into the rice steaming tank 32.

[0028] A long shaft 26 is movably inserted into the spiral shaft of the above-mentioned spiral rice inlet pipe 24. One end of the long shaft 26 is connected with a blocking block 27, and the blocking block 27 is located in the rice steaming tank 32 and its diameter is larger than the outer diameter of the spiral rice inlet pipe 24; the other end of the long shaft 26 is connected with the push rod assembly 28. By movably inserting the long shaft 26 into the spiral shaft and connecting one end of the long shaft 26 with the push rod assembly 28, when the push rod assembly 28 expands and contracts, it can drive the long shaft 26 to move back and forth. The long shaft 26 drives the blocking block 27 to move back and forth, realizing the opening and closing of the end face of the spiral rice inlet pipe 24. When the long shaft 26 moves towards the end away from the rice steaming tank 32, the blocking block 27 seals the spiral rice inlet pipe 24 to prevent steam leakage during rice steaming. When the long shaft 26 moves towards the end of the rice steaming tank 32, the blocking block 27 opens the spiral rice inlet pipe 24 to complete rice feeding. When feeding rice, the above-mentioned push rod assembly 28 and the rice inlet motor 25 are started synchronously.

By the expansion and contraction of the first push rod 281 to drive the connecting rod 282 to move, the connecting rod 282 drives the long shaft 26 to move. A spring is sleeved outside the part of the long shaft 26 between one end of the spiral rice inlet pipe 24 and one end of the connecting rod 282, which can make the long shaft 26 reset to the target position and reduce the impact during the movement.

[0031] The above-mentioned first proximity switch 283 and the second proximity switch 284 are arranged at intervals along the axial direction of the long shaft 26, and one of the proximity switches is opposite to one end of the connecting rod 282. In this embodiment, it is preferably arranged above the connecting rod 282. The first push rod 281 drives the long shaft 26 to move towards the rice steaming tank 32 until it stops at the second proximity switch 284. At this time, the circular blocking block 27 in the rice steaming tank 32 opens the spiral rice inlet pipe 24, and the rice grains fall into the rice steaming tank 32; after completing rice feeding, it drives the long shaft 26 to move in the reverse direction until it stops at the first proximity switch 283.
