Description

[Detailed Description of the Invention] The present invention relates to a drive device for derolling in a huller.

In other words, among the main and auxiliary rubber rolls, which have different rotational speeds, the rubber roll with the faster speed generally wears out faster, but the present invention is economical because both rubber rolls rotate at different speeds at different speeds, but wear out equally. Moreover, the present invention provides a simple structure that does not require a complicated interlocking structure, provides a strong rotational force, improves detachment, and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 is a side view of a part of the rice husking machine. Below the hopper 5 and below the feed roll 6, etc., there is a chamber escape 7 installed, and inside the chamber escape 7 there is a main rubber roll 1 and an auxiliary rubber roll 2. The rotating shaft 8 of the main rubber roll 1 is mounted on the metals 10, 10 of the side case 9, and the rotating shaft 8 is installed to be rotationally driven by the variable speed motor 3.

Further, the rotating shaft 11 of the sub-rubber roll 2 is attached to a metal 1 at the middle part of the support arm 12 in the side case 9.
3 and 13, and is installed so that the rotary shaft 11 is rotationally driven by a variable speed motor 4 fixed to the support arm 12, and the lower part of the support arm 12 is pivoted to a fixed support shaft 14, and the side part An operating cylinder 16 pivotally supported by a stay 15 on the outside of the case 9
The distal end of the piston rod 17 which extends further is connected to the upper end of the support arm 12 and is installed so as to be able to press the sub-rubber roll 2 in the direction of the main rubber roll 1.

Both variable speed motors 3 and 4 are installed to rotate at a predetermined high and low speed at different speeds and to rotate in opposite directions. Both variable speed motors 3 and 4 are connected to a control panel 19 equipped with a timer 18, By setting 18, when both speed change motors 3 and 4 rotate at a predetermined high and low speed at a differential speed and a certain period of time has elapsed, both speed change motors 3 and 4 are switched to rotate at a predetermined high and low speed at a differential speed. Similarly, the structure is such that it can be controlled to alternately switch between high and low speeds at regular intervals.

During the hulling operation, as shown in Fig. 2, both the main and auxiliary rubber rolls 1 and 2 rotate in the opposite direction to remove the paddy, but one of the rubber rolls 1 and 2 rotates at high speed and the rubber rolls 1 , 2 to promote disengagement.

In this state, both variable speed motors 3
is switched to a predetermined high and low speed rotation and rotates at a differential speed, and the rubber roll wears out faster at high speed, but both rubber rolls 1 and 2 are rotated alternately between high speed and low speed. They rotate at different speeds and wear out equally.

In this way, the present invention rotates the main and sub-rubber rolls, which rotate at predetermined high and low speeds at different speeds and rotate in opposite directions, respectively, by variable speed motors, and connects the variable speed motors to a control panel with a timer. Since the structure is configured so that the high-speed side is alternately switched to the low-speed side and the low-speed side is switched to the high-speed side at regular intervals, the main and auxiliary rubber rolls are alternately switched at high and low speeds at regular intervals. Since they rotate at high speed, both parts wear out equally, making it economical. Moreover, since both rubber rolls are rotationally driven by variable-speed motors, the structure is simple without requiring a complicated interlocking structure as in the past, and the advantage is that strong rotational force is applied to both rubber rolls, making it easy to remove and can be carried out suitably. has.
