Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feed regulating device in a test huller.

In other words, in a test hulling machine that has a reed roller and a control valve installed opposite each other in the upper supply section between the two de-rolls, the rice huller usually performs so-called two-time rolling to completely remove the rice, and during the double-rolling. The opening degree of the control valve must be changed from the first time, but the present invention can easily adjust the opening degree and change the opening degree reliably, and has a simple structure. It is provided to enable suitable implementation.

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

FIG. 1 shows a sectional view of the main parts of a test huller, in which a supply hopper 8 is installed at a distance above a removing chamber 7 in which both removing rolls 1 and 2 are mounted on an axis. Lead roller 3 is located above between 1 and 2.
and a control valve A are installed opposite each other, and the inclined upper side of the control valve A is pivoted on a support shaft 9, and when the control valve A is moved away from the lead roller 3 and the opening degree is increased, the control valve A will be rubbed once, and the control valve When A is brought close to the lead roller 3 side and the opening degree is made small, it is installed and configured so that it rubs twice.

A projecting piece 10 is integrally formed on the upper end side of the control valve A above the pivot portion of the support shaft 9, and a female threaded portion 12 formed on the side wall 11 in the vicinity thereof has an adjusting screw body. B is screwed together, and a large-diameter head b for rotational operation is integrally formed on one end side of the adjusting screw body B, and a long support is slidably inserted into the internal axis of the adjusting screw body B. A round hole portion 14 is provided at the axis of the large diameter head b so that the log portion 13 on one end side of the rod C can fit therein.
Grooves 5 and 6, which are cross-shaped when viewed from the end surface side of the large-diameter head b, are formed across the round hole portion 14, but one groove 5 is formed from the end surface of the large-diameter head b. The other groove 6 is formed so as to become deeper along the end surface of the large diameter head b, and the other groove 6 is formed so as to become shallower along the end surface of the large diameter head b.
The pin 4 is inserted into the groove 3 so as to be perpendicular to the axial direction, and both ends of the pin 4 are fitted into the grooves 5 and 6.

The support rod C is formed to extend long enough to extend from the adjusting screw body B and fit into the hole 15 in the protruding piece 10 of the regulating valve A, and the seat plate 16 and the protruding piece 10 are joined to the end face of the adjusting screw body B. A compression spring 17 is interposed around the support rod C in between, and a locking plate 18 that can be joined to the outer surface of the projection piece 10 is fitted and locked at the tip of the support rod C that protrudes from the projection piece 10. Install and configure.

Therefore, the huller configured as described above is used for testing purposes in a hulling plant, etc., but the rice supplied to the supply hopper 8 is sent downward between the control valve A and the feed roller 3 by rotation of the lead roller 3. , and are removed by both removal rolls 1 and 2.

In that case, since it is for testing, it will be rubbed twice to completely release it, but during the first rubbing, as shown in Figures 1 to 3, the pin 4
is fitted into the groove 5, and while rotating the adjusting screw body B with the large diameter head b, the forward and backward adjustment is performed by screwing into the female threaded portion 12, and at the same time by engaging with the supporting rod C which moves forward and backward. Rotate control valve A to set the opening degree.

In addition, for the subsequent double rubbing, grasp the log portion 13 of the support rod C and pull it outward until the pin 4 comes out of the groove 5, then rotate it 90 degrees.
The tension of the tension spring 17 causes the pin 4 to engage with the groove 6, and as shown in FIGS. 6 to 8, the control valve A is pulled by the support rod C.
The opening degree is adjusted so that the slope becomes steeper and the distance from the lead roller 3 becomes narrower, thereby making it possible to effectively perform double sliding.

In this way, the present invention provides a test huller in which a lead roller 3 and a regulating valve A are installed oppositely in the upper supply section between the two derolling rolls 1 and 2, and in which a movably adjustable regulating screw body B is provided. The rotatable control valve A is connected to the support rod C to be engaged, and the support rod C is engaged to the adjustment screw body B so that the engagement position can be changed freely by engaging the pin 4 and the grooves 5 and 6. Since the opening degree of the control valve A can be adjusted, the opening degree of the control valve A can be set accurately using the adjustment screw body B during the first rubbing, and the opening degree of the control valve A can be set accurately using the adjustment screw body B during the first rubbing. The opening degree of the control valve A can be changed by simply changing the engagement between the pin 4 and the groove 6 using the support rod C without operating the body B.
The opening degree can be easily adjusted and the opening degree can be changed reliably, and it has a feature that it can be implemented suitably with a simple structure.
