[0004] The utility model solves its technical problem by adopting the following technical solutions:

[0005] A rocker arm assembly of a rice huller includes a rocker arm arranged on the rice huller. At one end of the rocker arm, there is a rocker arm rotating shaft, and a bearing for the rocker arm is arranged in a matching manner on the rocker arm rotating shaft to enable the rocker arm to rotate smoothly. There are two sets of the rocker arms arranged symmetrically left and right. At the front end of the rocker arm, a rotating cylinder is rotatably arranged, and the shaft ends of both ends of the rubber roll are inserted and fixed in the rotating cylinder. By rotating the position of the rocker arm, the distance between the rubber roll and another rubber roll arranged on the rice huller can be adjusted.

[0006] Preferably, at the other end of the rocker arm, a rotating cylinder sleeve is fixedly arranged through bolts, and a rotating cylinder slewing bearing is embedded in the rotating cylinder sleeve.

[0007] Preferably, the rotating cylinder is inserted into the rotating cylinder slewing bearing and rotates under the action of the rotating cylinder slewing bearing.

[0008] Preferably, a locking screw hole seat is arranged on the rotating cylinder, and a locking bolt passes through the locking screw hole seat to fix the shaft end of the rubber roll inserted in the rotating cylinder.

[0009] Preferably, a buffer rubber pad cylinder is embedded in the rotating cylinder, and the shaft end of the rubber roll is inserted into the buffer rubber pad cylinder to effectively absorb energy from vibration.

[0010] Preferably, a weight reduction hole is arranged on the rocker arm to reduce the weight on the premise of meeting the structural strength of the rocker arm.

[0011] The advantages and positive effects of the utility model are: simple structure, convenient installation, no need to use a puller to remove the bearing at the shaft end of the rubber roll, and it is convenient to install the rubber roll, with high rotational coaxiality.
