It should be understood that the specific embodiments described herein are intended to explain the present application, and are not intended to limit the present application.

[0035] Please refer to the accompanying drawings Figures 1-11 The purpose of the embodiment is to provide a rice milling pressure continuous adjustment assembly (4), which comprises: a main pressing block (48) floating up and down in a rice milling cavity (511) and used for keeping the rice milling pressure in the rice milling cavity (511) constant; the top of the main pressing block (48) is connected with a flexible member (46), the flexible member (46) is always in a relaxed state when the main pressing block (48) applies the rice milling pressure, and the flexible member (46) is one of a rope, a cord, a wire or a chain; the overall mass of the main pressing block (48) is basically not affected when the flexible member (46) is always in the relaxed state; a temporary storage water cavity is arranged in the main pressing block (48), and the temporary storage water cavity is flexibly connected with a water injection counterweight unit (47) on one side of the main pressing block (48); the water injection counterweight unit (47) injects water into the temporary storage water cavity or pumps out water in the temporary storage water cavity to change the rice milling pressure applied by the main pressing block (48). By injecting water into the temporary storage water cavity in the main pressing block (48) or pumping out water from the temporary storage water cavity, the overall mass of the main pressing block (48) can be continuously increased or decreased, which can better improve the rice milling effect compared with applying a counterweight block or other ways, the rice milling pressure can be dynamically adjusted according to the type of rice, and the accuracy of the rice yield detection can be improved. It should be noted that the mass of the main pressing block (48) is changed by water injection to adjust the rice milling pressure, so that the adjustment of the rice milling pressure is continuous in value, and different rice milling requirements can better meet the use requirements.

[0036] In the embodiment, the water injection counterweight unit (47) is provided with a water pump (473) connected to one end of a water injection pipe (472) and a water suction pipe (474) respectively, and the other end of the water injection pipe (472) and the water suction pipe (474) are connected to the temporary water cavity and the water storage tank (475) respectively; the temporary water cavity and the water storage tank (475) are connected through a drain pipe (471). The water injection pipe (472), the water suction pipe (474) and the drain pipe (471) are all flexible hoses, so that the water injection counterweight unit (47) basically does not affect the overall mass of the main pressure block 48 and the applied rice milling pressure.

[0037] The above-mentioned continuous adjustment assembly 4 of rice milling pressure can be applied to a rice milling device, which comprises a rice milling assembly 5; The rice milling assembly 5 is provided with a rice milling unit 51, a screen cleaning unit 53, and a rice milling cavity cleaning unit 52, a roller knife cleaning unit 55 and a screen provided on a moving unit 54.

Specifically, the rice milling unit 51 is provided with a rice milling box body 516, and the roller knife 515 in the rice milling box body 516 is in transmission connection with the second driving device 514; the bottom of the main pressure block 48 is a pressure combined arc surface 481; the pressure combined arc surface 481 and the screen constitute at least part of the rice milling cavity 511. At this time, the pressure combined arc surface 481 and the screen are located in the rice milling box body 516 and thus constitute the rice milling cavity 511, and the roller knife 515 rotates at high speed to perform the rice milling work. Since the main pressure block 48 is in sliding connection with the rice milling box body 516, the main pressure block 48 will produce slight floating during the rice milling process. It should be pointed out that the rice milling effect can be coarsely adjusted by changing the pressure applied by the main pressure block 48, and the rice milling effect can be finely adjusted by changing the rotating speed of the roller knife 515. The adjustment strategy of giving priority to the counterweight and giving priority to the rotating speed can further improve the rice milling effect.

It should be noted that the roller cutter 515 performs the rice whitening work in the rice milling cavity, and the arc-shaped screen 518 leaks the chaff generated by the rice whitening.

[0041] It should be noted that the screen cleaning unit 53 comprises fixedly arranged pen-shaped steel brushes 531 and 532, and the screen is in transmission connection with a fourth driving device 533.
