Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing technology, and in particular to a swing frame adjustment roller mechanism for a rice hulling and milling combined machine. Background Technology
[0002] Currently, the common method for removing rice husks is to use the squeezing motion created by two rubber rollers pressed together to tear the husks. However, as the rice hulling machine continues to run, the rubber rollers will wear down, increasing the gap between the two rollers and causing a decrease in the husk breaking rate.
[0003] Existing equipment typically pushes one of the rubber rollers to bring the two rollers closer together. Since most rubber rollers are driven by belts to rotate the pulleys on the rollers, when the rollers are displaced, the belts that transmit power between the pulleys will loosen and fall off, requiring replacement with shorter belts, which is quite troublesome. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a swing frame adjustment roller mechanism for a rice hulling and milling combined machine to solve the above problems.

The roller group includes a fixed roller and an adjustment roller arranged adjacent to each other. A rotating shaft one and a rotating shaft two are respectively installed at one end of the fixed roller and the adjustment roller. One end of the rotating shaft one and the rotating shaft two passes through the machine body and is respectively installed with a belt pulley one and a belt pulley two.

[0025] Furthermore, it also includes a support frame for supporting the first and second fixed plates. A drive motor is installed inside the support frame, and the output end of the drive motor is equipped with a pulley four that cooperates with the belt.

[0040] The receiving area is equipped with a pushing device to drive the second rotating shaft to move upward along an arc-shaped trajectory in the arc-shaped groove 4 in the direction of the first rotating shaft, that is, to move the second rotating shaft to the upper left of its original position.
[0041] By adopting the above technical solution, when the rubber roller wears and the distance between the rubber rollers needs to be adjusted, the pushing device can drive the rotating shaft two to gradually rise along the arc groove, so that the adjusting rubber roller and the second pulley can move upward synchronously.
