[0019] The specific implementation methods, structures, features and functions of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] The automatic rice and water distributing machine of the present invention is characterized in that a transmission shaft 1 is installed in the middle of a frame 18 through a bearing, a bevel gear A4 is fixedly installed in the middle of the transmission shaft 1, a water distribution crank 13 and a rice leaking crank 20 are fixedly connected at the front and rear ends respectively, the water distribution crank 13 and the rice leaking crank 20 are respectively hinged to a water distribution connecting rod 14 and a rice leaking connecting rod 19, the water distribution connecting rod 14 is hinged to a slider water distribution cup 15, a slider on the slider water distribution cup 15 is inserted into a groove provided on the frame 18, an overflow device 16 is inserted into the slider water distribution cup 15, and the overflow water is The device 16 is connected to the frame 18, the overflow device 16 is connected to the water distribution pipe 12, the water distribution pipe 12 is connected to the water distribution valve 11, the water distribution valve 11 is installed at the bottom of the water tank 9, the rice leakage connecting rod 19 is hinged to the rice matching slider 3, the rice matching slider 3 is stuck in the guide rail groove 2, the guide rail groove 2 is fixedly connected to the bottom of the rice box 5, the rice box 5 is installed on the frame 18, the guide rail groove 2 is connected to the leakage rice pipe 17, the frame 18 is installed with a stepping motor 10, the output shaft of the stepping motor 10 is installed with a bevel gear B7, and the bevel gear B7 is meshed with the bevel gear A4.

[0021] The upper and lower surfaces of the guide rail groove 2 are respectively provided with staggered rice leakage holes, and the upper rice leakage hole is communicated with the hole at the bottom of the rice box 5.

[0022] One end of the rice-matching slider 3 is provided with a through hole.

[0023] The meter matching slide block 3 can slide left and right in the guide rail groove 2.

[0024] The slide block water dispensing cup 15 can move up and down in a groove arranged on the frame 18 .

[0025] A water inlet valve 8 is installed on the water tank 9, and a rice box cover 6 is covered on the rice box 5.

[0026] When in use, the stepper motor 10 is controlled to work by the touch screen and PLC. There is an input box for setting the number of people eating and a rice and water distribution button on the touch screen, because the rice and water distribution is the amount of food for one person, and it is repeated for many people. The inner pot of the electric rice cooker is placed below the slider water distribution cup 15, and the controller controls the stepper motor 10 to rotate, driving the transmission shaft 1, the water distribution crank 13 and the rice distribution crank 20 to rotate, and the slider water distribution cup 15 and the rice distribution slider 3 just reciprocate to distribute rice and water.
