A bearing is also arranged in the bearing sliding seat, and the two ends of the rotating shaft of the upper rubber roll are arranged in the bearings in the bearing sliding seat. An electric telescopic driving cylinder for driving the bearing sliding seat to move up and down is fixedly arranged on the rubber roll frame.

[0006] Preferably, a sliding groove is arranged on the side of the bearing sliding seat, and the sliding groove is slidably clamped on the inner side of the guide rail block.

[0007] Preferably, a lubricating hole is arranged on the inner side surface of the sliding groove, and lubricating grease is arranged in the lubricating hole.

[0008] Preferably, a sponge is filled in the lubricating hole, the lubricating grease soaks in the sponge, and the outer side wall of the sponge contacts the side surface of the guide rail block, thereby providing good lubrication.

[0009] Preferably, a spring is also installed in the lubricating hole to push the sponge outwards to press against the side surface of the guide rail block to provide good lubrication.

[0010] Preferably, a limiting block is arranged at the lower end of the guide rail block for limiting the downward movement of the bearing sliding seat.

[0011] The advantages and positive effects of the present utility model are as follows: By driving the bearing slide by the electric telescopic driving cylinder, it is convenient to adjust the gap between the upper sizing roller and the lower sizing roller, thereby better peeling the paddy. In addition, a good lubrication is provided through the lubrication structure to facilitate its smooth and stable movement. Description of the Drawings
