Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hulling machine having a rotary sorting tube for separating and sorting paddy and brown rice while rotating.

Problems to be Solved by the Invention By rotating after being supplied with ground rice that has been descaled by a deweighing device, some of the grains are scooped up in the direction of rotation by the four parts formed on the inner circumferential surface. However, it is necessary to adjust the paddy and brown rice to maintain the optimal layer thickness. Moreover, while maintaining this adjustment, the sorting efficiency is increased by adjusting the sorting efficiency to be high or low depending on the quality of the removal rate.

Means for Solving the Problem This invention provides a supply control valve (2) for adjusting the amount of paddy supplied to the agitating section (1), and a de-weighing section (1) that includes A layer thickness sensor (4) detects the thickness of the piled rice layer in the rotary sorting cylinder (3) which separates and sorts paddy and brown rice while rotating. (2)
The layer thickness sensor (4) and the supply control valve (2) are provided in conjunction with each other to operate in the closing direction, and furthermore, by adjusting the amount of brown rice sorted and separated in the rotary sorting cylinder (3) to the side that increases. ) is maintained, and the rice huller is constructed such that the layer thickness sensor (4) and the supply control valve (2) are operated in an increasing direction.

Functions and Effects of the Invention The crushed rice that is crushed by the hulling section (1) is supplied to the rotary sorting tube (3), where it is separated into paddy and brown rice. When the layer thickness of the grains inside increases beyond a certain level, the layer thickness sensor (4) is activated, and the supply control valve (4) is activated according to the increase.
2) acts in the direction of closing, and when the thickness of the correspondence decreases,
The feed control valve (2) is actuated in the opening direction by the layer thickness sensor (4) to maintain a constant layer thickness of the grains in the sorting tube (3). Furthermore, when the separation accommodation M of brown rice in the sorting cylinder (3) is adjusted to the increasing side according to the unweighing rate of the washed-out rice, etc., the operational relationship between the layer thickness sensor (4) and the supply control valve (2) becomes '' While maintaining the same conditions as described in Section 2 above, both the layer thickness sensor (4) and the supply control valve (2) are operated to increase the amount of rice being removed, and the amount of separated brown rice in the sorting cylinder (3) is adjusted. increase.

In this way, the layer thickness of the grains in the sorting tube (3) is automatically adjusted to increase or decrease the amount of removed rice using the layer thickness sensor (4), and the layer thickness is kept constant, and the deweighing section has a high deweighing efficiency. In addition to increasing the amount of paddy supplied to the demixing section (1), the layer thickness sensor (4) is also installed in the rotary sorting tube (3).
Since this method maintains the supply amount adjustment of -1-marked paddy while increasing the detection layer, highly efficient dehulling and sorting can be achieved while maintaining the best sorting. Moreover, the control of the supply control valve (2) by the sensor (4) is controlled by the sorting cylinder (3).
Even if the amount of brown rice to be sorted and separated is increased and the supply control valve (2) is opened, the operation is simple because it is automatically maintained based on this value.

In addition, (41) is the sorting tube (3) that removes the rice from the spiral gutter (8)
) is a brown rice thrower that discharges brown rice from the helical portion 0 to the outside of the machine.The rice thrower 103 is a paddy thrower that returns the paddy sorted in the sorting tube (3) to the paddy hopper (5).
It is.

Next, the effect will be explained. The amount of paddy supplied to the paddy hopper (5) is adjusted by the supply control valve (2), and the crushed rice removed by the dehulling roll (1) (1) flows down the air path (7). The rice husks are removed and fed through the helical part (8) to the front part of the transfer helix 00 in the rotary sorting tube (3) by the thrower (41). The rolled rice in this transfer helix 0e is transferred backward by the transfer helix 09), and the rice is transferred to the rear by the transfer helix 09).

When the layer thickness of the layer thickness sensor (4) reaches a certain level, the arm 0 rotates in the direction of pushing the rod (c), and the connecting plate (c)
rotates in the direction of pushing the rod oO using the rod connection hole (a) as a fulcrum, the supply control valve (2) rotates to the closing side, and the layer thickness of the layer thickness sensor (4) is detected. When becomes below a certain level, the supply control valve (2) rotates in the opening direction. Furthermore, the control valve (c)
When adjusting in the direction of increasing the amount of brown rice taken, the arm 0 side rotates in the direction of pulling the rod (to), and the connecting hole (A) of the connecting plate (to) moves with the rotation of arm ■. As a result, the supply control valve (2) is rotated via the rod θO in the opening direction, and the layer thickness sensor (4) is also rotated via the rod (c) in the direction of increasing the layer thickness. 2) and layer thickness sensor (4), the reference values have moved to the increased side.
According to this standard, the layer thickness sensor (4) and the supply control valve (2)
) will be controlled in conjunction with each other.
