Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grain sorting device for sorting mixed rice of paddy and brown rice using a rotating sorting cylinder having a large number of pot holes on its inner circumferential surface. It is something.

[Prior Art] There is a grain sorting machine that sorts a mixed rice of paddy and brown rice by rotating a rotary sorting cylinder, which has a large number of pot holes on its inner circumferential surface, around a horizontal axis. Inside this rotary sorting cylinder, an intermediate reduction shelf is installed obliquely in the middle part in the longitudinal direction from the supply side to the discharge side below the finished rice gutter, and a discharge side reduction shelf is installed obliquely on the discharge side. Grains that have not reached the finishing rice gutter in the upper part of the grains that have been pumped up by the sorting tube, that is, grains that are mixed with a relatively large amount of brown rice, are transferred from the front side of the rotating sorting tube to the rear side of the rotation. The grains mixed with a relatively large amount of brown rice are returned to the rear part of the fluidized bed of grains to be sorted, which is formed by the rotation of the rotary sorting cylinder. This increases the chances of the rice entering the pot hole, increasing the efficiency of collecting brown rice into the finished rice trough.

[Problems to be solved by the invention] However, in this conventional device, the intermediate reduction shelf and the discharge side reduction shelf are disposed in a fixed state extending in the longitudinal direction below the finishing rice gutter. There was a problem in that the intermediate reducing shelf and the discharge side reducing shelf did not effectively reduce grains containing a large amount of brown rice, due to differences in grain size or variety due to the difficulty of shedding.

Therefore, the present invention is designed to respond to changes in the sorting state based on differences in variety due to the size of the grain or the difficulty of shedding.
The relative position between the intermediate reduction shelf and the discharge side reduction shelf can be adjusted, and in conjunction with this adjustment, the finished rice control valve of the finished rice gutter can also be adjusted in relation to the intermediate reduction shelf and the discharge side reduction shelf. This is intended to improve the sorting efficiency by allowing a large amount of grains containing a large amount of brown rice to flow down and return in the return shelf, and by allowing a large amount of brown rice to be received by the finished rice control valve in the finishing rice gutter.

[Means to solve the problem]

The technical means of the present invention for solving such technical problems is to provide a finished rice with a finished rice regulating valve 16a in a rotary sorting cylinder 11 which has a large number of pot holes in its inner peripheral surface and rotates around a horizontal axis. The gutter 16 is suspended horizontally, and an intermediate reduction shelf 23 is installed at the intermediate portion in the longitudinal direction from the supply side to the discharge side below the finished rice gutter 16, and a discharge side reduction tlXII 24 is installed diagonally on the discharge side. , the discharge side return shelf 24 is disposed lower than the intermediate return shelf 23, and at least the discharge side end of the intermediate return shelf 23 is configured to be freely adjustable in the longitudinal direction above the discharge side return shelf 24; 24 and finishing rice @l! The present invention has a structure of a control device for a grain sorting device, which is characterized in that it controls the 16 finished rice control valves 16a in relation to each other.

[Function and effect of the invention]

When performing sorting work in the rotary sorting tube 11, the sorting situation in the rotary sorting tube 11 changes depending on the size of the grains or differences in varieties due to difficulty of shedding, etc., and the situation in which the grains are pumped in the rotary sorting tube 11 changes. changes, and when the grains can be received on both the intermediate reduction shelf 23 and the discharge side reduction shelf 24 in the part of the discharge side reduction shelf 24, the discharge side of the intermediate reduction shelf 23 is moved to the discharge side. , give priority to the grains with a large amount of brown rice received on the intermediate reduction shelf 23 and give them an opportunity to fit into the pot hole of the rotary sorting cylinder 11, increasing the opportunity to pump up the brown rice, and in the part of the discharge side reduction shelf 24, When the grains can be received on both the intermediate reduction shelf 23 and the discharge side reduction shelf 24,

Ru.

The mixed rice of brown rice and paddy falls into the sliding rice receiving trough 7, and is lifted and supplied to the starting end side of the supply trough 14 on the rotary sorting cylinder 11 side via the mixed rice hopper 9 in the mixed rice lifting machine 8. The feed helix 13 in the feed gutter 14 supplies the feed to the feed side end of the rotary sorting tube 11 .

Next, the mixed rice is scooped up by the pot hole of the rotary sorting cylinder 11 which is rotating clockwise in FIG. The rice falls into the supply gutter 14 and is sorted, and the unsorted mixed rice that has fallen into the feed gutter 14 is fed again into the rotary sorting tube 11 from the conveyance end of the feed gutter 14 by the feed helix 13 and is re-sorted. Ru.

Further, the finished rice that has fallen into the finishing rice gutter 16 is conveyed to the finishing rice flow lower cylinder 17 by the finishing rice helix 15, and is transferred to the finishing rice flow grain plate 18.
While falling into the finished rice receiving trough 19, it is sorted by a sorting wind and taken out of the machine by the finished rice lifting machine 2o.

The sorted paddy sent to the discharge side end of the rotary sorter @i11 enters the pumping cylinder 21, is pumped up by the pumping cylinder 21, falls into the upper paddy return gutter 22, and is returned to the rice dumping section 1. After that, it is subjected to the shedding action again in the shedding section 1.

As described above, the paddy layer sorting work is performed, and when performing the sorting work in the rotary sorting cylinder 11, two grains are large in size, and two grains are small in size.

It is necessary to sort grains of various types, such as the mixture of large grains and small grains or the degree of difficulty of dehulling. Grain grains are pumped up lower by the pot holes, and grains with a smaller grain size are pumped higher by the pot holes, so depending on the characteristics of the grains, the sorting situation in the rotary sorting cylinder 11 changes, and the intermediate reduction shelf 23 and the grains fall to the discharge side reduction [24] and the reduction state changes.

In this way, the situation in which the grains are pumped up in the rotary sorting tube 11 changes, and the state in which the grains fall and return to the intermediate reduction shelf 23 and the discharge side reduction shelf 24 changes, so that the grains are dropped to the intermediate reduction shelf 23 and the discharge side reduction shelf 24. , intermediate reduction shelf 23 and discharge side reduction! 24, adjust the intermediate reduction shelf 23b of the intermediate reduction shelf 23 by using the operating lever 27 to move the intermediate reduction shelf 23b to the discharge side.
Priority is given to the grains on the adjustment intermediate reduction shelf 23b, which is located above and receives grains with a high brown rice ratio, over the grains on the discharge side reduction shelf 24, which is located below and receives grains with a low brown rice ratio. The rotary sorting cylinder 1 gives priority to grains with a lot of brown rice.
This increases the chance of pumping up the brown rice by providing an opportunity for the brown rice to fit into the hole in the pot 1.At the same time, the finished rice control valve 16a of the finished rice gutter 16 is adjusted to the side where the area of the finished rice is expanded. This makes it possible to increase the amount of brown rice recovered and improve sorting efficiency.
