Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement of a sorting device in a huller.

(Prior Art) In a conventional huller that can be sorted by a manseki net, the finished rice that leaked through the manseki net was sent out of the machine by a finishing rice thrower.

(Problems to be solved by the invention) In the case of the above-mentioned conventional technology, when looking at what was sent out by the finishing rice thrower, it was unavoidable that some amount of paddy was mixed into the brown rice, and it was necessary to remove it to eliminate this If the rate is increased, the brown rice will be scratched and the rate of occurrence of damaged rice will increase. In addition, it was impossible to prevent the paddy from being mixed only by adjusting the stones for various changes such as variety and drying unevenness.

(Means for Solving the Problems) In the device of the present invention, a finishing rice hopper having a discharge outlet of a finishing rice thrower is provided above a mixed rice hopper facing a discharging outlet of a rice milling thrower. A finishing brown rice discharge pipe with a sorting mesh installed between the finishing rice hopper and the mixed rice hopper so as to swing, and a discharge port facing the outside of the machine under the starting end side of the sorting mesh. And a leaking substance discharge branching plate for changing the branching position in the transfer direction of the mesh is disposed below the sorting mesh. It is a thing.

(Operation) The polished rice subjected to the desorption in the desorption chamber is fed into the mixed rice hopper by the sludge for polishing rice. The polished rice that has entered the mixed rice hopper falls on the manseki device and is sorted. The sorting with the Mangoku device is divided into paddy and a mixture of paddy and brown rice by the upper net, the paddy and brown rice that passed through the upper net by the middle net, and the paddy and brown rice that passed through the middle net by the lower net. Is further divided into paddy and brown rice. The brown rice that has leaked through the manseki device is sent to the finished rice hopper by the finished rice sloa. On the other hand, the paddy that could not leak through the Mangoku device is returned to the defunnel by the returning paddy. The brown rice that has entered the finishing rice hopper falls on the sorting net and is sorted.
The spillage discharge branch plate disposed below the sorting net is set such that a substantially intermediate portion in the transfer direction of the net is at the branch position. The brown rice dropped on the sorting net is sorted into good brown rice and good brown rice, paddy, and rice by the swinging sorting net, and the good brown rice leaked at the start end side of the net is finished brown rice discharged by the branching plate. Those discharged to the pipe side and leaking from the approximately middle part of the net at the end side, or those that could not leak from the mesh, that is, some good brown rice, paddy and rice gruel are mixed by the branch plate. It is returned to the rice hopper side, separated and discharged as brown rice, and re-selected through the mixed rice hopper.

(Embodiment) The drawings show a hulling machine A embodying the present invention. The hulling machine A is provided with a roll-type dechamber a, a mannequin device b, and a Karako-type dust sorting section c. Reference numeral 1 denotes a funnel that can be discharged to the upper part of the chamber a. The manseki device b is an upper net 2, a middle net 3, a lower net 4,
It is a one-sided installation of three-stage sorting nets. 5 is
It is a miller for slender rice that is arranged in the lower part of the chamber. 6 is a mixed rice hopper, and the discharge port 5a of the milled rice thrower 5 is exposed in the mixed rice hopper 6. A finishing rice hopper 7 is provided above the mixed rice hopper 6. Reference numeral 8 denotes a finishing rice thrower disposed below the manseki device b, and an outlet 8a of the finishing rice thrower 8 faces the inside of the finishing rice hopper 7. A sorting net body 9 is mounted between the finishing rice hopper 7 and the mixed rice hopper 6 so as to perform a swinging motion. The sorting net body 9 is disposed so as to be slightly inclined downward from the starting end side immediately below the dropping port 7a of the finishing rice hopper 7 toward the terminating side that is gradually away from the dropping port 7a. A receiving port 10b of a finished brown rice discharging pipe 10 with a discharging port 10a facing the outside is faced below the starting end side of the sorting net body 9. Reference numeral 11 denotes a leakage plate discharging branch plate for switching the leakage products from the sorting net body 9 to the receiving port 10b side of the finished brown rice discharge pipe 10 and the mixed rice hopper 6 side.
1 is located below the sorting net body 9 and is configured to be adjustable in angle so as to change the branching position of the sorting net body 9 in the flow-down direction. 6a is an outlet of the mixed rice hopper 6,
Reference numeral b is a shutter for adjusting the amount of mixed rice for adjusting the opening amount of the outlet 6a, and reference numeral 12 is a return paddle.

(Effect of the device) According to the present invention, the finished rice sent by the finishing rice thrower after being sorted is finished and sorted by the sorting net body that swings once without being discharged to the outside of the machine, and only the good brown rice is sorted. Some of the good brown rice and paddy and rice grains discharged to the outside of the machine are returned to the mixed rice hopper for re-selection as rice, so the sorting performance is further improved and the good brown rice is not affected by various conditions of the paddy. The effect is that you can select only those and no complicated adjustment is required.
