[0024] One embodiment of the present invention is as follows:

[0025] The rice mill discharge port adjustment mechanism includes a shell 2, inside which a counterweight part, a linkage part and a pressure part are installed. The counterweight part transmits the driving force generated by gravity to the pressure part through the linkage part to adjust the position of the pressure plate 11, thereby achieving the effect of adjusting the discharge port pressure.

[0026] The counterweight part includes a flow regulating rod 5 and a rotating shaft 3. The rotating shaft 3 is connected to the shell 2 in a rotatable manner. Both ends of the rotating shaft 3 pass through the outside of the shell 2. Both ends of the rotating shaft 3 are fixedly connected to the flow regulating rod 5. There are two flow regulating rods 5 in total. The two flow regulating rods 5 are parallel to each other. When the flow regulating rod 5 rotates, it will drive the rotating shaft 3 to rotate.

[0027] The flow regulating rod 5 is connected with a pressure weight 4 in an interference fit manner. There is static friction between the pressure weight 4 and the flow regulating rod 5. The static friction ensures that the pressure weight 4 can move on the flow regulating rod 5 by manpower, and also ensures that the pressure weight 4 will not slide with the flow regulating rod 5. The pressure weight 4 can move on the flow regulating rod 5. The pressure weight 4 is at different positions of the flow regulating rod 5. Due to the lever principle, the torque that causes the flow regulating rod 5 to rotate is also different. The closer the pressure weight 4 is to the end of the flow regulating rod 5, the greater the torque generated, and the closer it is to the inner end of the flow regulating rod 5, the smaller the torque generated.

[0028] In a further embodiment, the flow regulating rod 5 is configured as a screw rod, the pressure weight 4 is configured as a nut, and the flow regulating rod 5 and the nut are connected by meshing.

[0029] The linkage part includes a first connecting rod 6 and a second connecting rod 10, and two of the first connecting rod 6 and the second connecting rod 10 are provided, which are divided into two groups. The first connecting rod 6 and the second connecting rod 10 are hinged by a pin 9, and the second connecting rod 10 and the connecting seat are hinged by the pin 9, wherein the upper end of the first connecting rod 6 is fixedly connected to the two ends of the rotating shaft 3 respectively, the lower end of the first connecting rod 6 is hinged to the second connecting rod 10, and the second connecting rod 10 is hinged to the connecting seat. When the rotating shaft 3 rotates clockwise, the first connecting rod 6 is driven to rotate clockwise, so that the second connecting rod 10 drives the connecting seat and the pressure plate 11 to move toward the discharge port, thereby increasing the discharge port pressure. When the rotating shaft 3 rotates counterclockwise, the first connecting rod 6 is driven to rotate counterclockwise, so that the second connecting rod 10 drives the connecting seat and the pressure plate 11 to move in the opposite direction of the discharge port, thereby reducing the discharge port pressure.

[0030] The pressure part includes a connecting seat, a pressure plate 11 and a guide shaft 7. The second connecting rod 10 is hinged to the connecting seat. The pressure plate 11 is fixedly arranged on the side of the connecting seat away from the second connecting rod 10. A through hole is arranged in the middle of the pressure plate 11. The guide shaft 7 passes through the through hole. The shell 2 also includes a front panel 8. One end of the guide shaft 7 is fixedly connected to the inner side surface of the front panel 8.

[0031] One end of the shell 2 is connected with a flange 1, and the shell 2 is connected to the discharge port of the rice mill through the flange 1, and the rice with the husk removed is discharged from the discharge port.

[0032] A partition plate 12 is also provided in the shell 2 , and the partition plate 12 is parallel to the pressure plate 11 .

[0033] The upper panel of the housing 2 is provided with an observation port 13, which is made of transparent organic glass 14 and is used to observe the internal operation of the device and the rice output.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
