Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a flow path switching device in a stone removal machine.

(Prior art) In the conventionally known technology, a rice miller a is provided with a feeding elevator b.
A switching valve d is provided between the rice milling machine a and the stone removing machine c, a return path f is provided between the switching valve d and the loading port e of the supply elevator b, and a switching valve d is provided between the switching valve d and the stone removing machine c. A supply path h was provided between the supply section g and the measuring device j was supplied via the elevator i.

(Problems to be Solved by the Invention) In the known method, a switching valve d is provided between the rice milling machine a, which is outside the stone removing machine c, and the rice removing machine c, and the rice is supplied from the switching valve d through the return path f. The structure was very complicated because the supply path h was provided between the switching valve d and the supply section g of the destoner c.

(Means for solving the problem) The present invention has thus been devised, and has a milled rice supply port 2 in the upper part of the case 1 of the de-stoning machine, and a rocking de-stoning sorting plate 5 in the lower position of the interior 3 of the case 1. Stone removal device 4
Between the polished rice supply port 2 and the rocking stone removal sorting plate 5, there is a flow path from the polished rice supply port to the rocking stone removal screening plate 5, and a flow path from the polished rice supply port 2 to the rocking stone removal screening plate 5. It is used as a flow path switching device in a stone removing machine which is provided with a flow path leading to the outside of the stone removal sorting plate 5 and a switching valve 19 therefor.

(Example) An example of the present invention will be described with reference to the drawings.
is the whole case, with white rice supply port 2 installed at the top,
A stone removal device 4 is provided at a lower position in the interior 3. Reference numeral 5 designates an oscillating stone removal sorting plate, 6 a grain outlet, and 7 a stone waste removal section.A blower winnower 8 is installed below the oscillating stone removal sorting plate 5 to blow air onto the oscillating stone removal selection plate 5. give. 9 is the wind fuselage.

Therefore, a swinging supply plate 10 that sings in the T direction is provided at the bottom of the polished rice supply port 2, and the swinging supply plate 10
A oscillating rice sorting body 11 which similarly swings in the T direction is provided below the oscillating rice sorting body 11, and a small rice receiving trough 12 is provided below the oscillating rice sorting body 11. 13 is a discharge gutter of the rice receiving gutter 12. Numerous protrusions 15 are provided on the bottom surface 14 of the swinging supply plate 10 to move the brown rice 16 and polished rice 17 toward the outlet 18 of the swinging supply plate 10.

Reference numeral 19 denotes a switching valve. When switched as shown by the solid line, brown rice 16 and white rice 17 are supplied to the small rice receiving trough 12 and not supplied to the rocking stone extraction sorting plate 5. When switched as shown by the temporary line, brown rice 16 and white rice 17 are supplied to the oscillating stone extraction sorting plate 5. The polished rice 17 is supplied to the oscillating rice sorting body 11, and is supplied to the channel leading to the oscillating stone removal sorting plate 5 via the oscillating rice sorting body 11.

Reference numeral 20 denotes a discharge port of the oscillating rice sorting body 11, which serves as a supply port for the oscillating stone extraction and sorting board 5.

2 to 5 show other embodiments, and in FIG. 2, the swinging supply plate 10 of FIG. , either directly to the oscillating millet sorter 11 or to the millet receiving trough 12.

FIG. 3 shows a configuration in which the swinging supply plate 10 and the swinging rice sorter 11 of FIG. 1 are removed, and only the switching valve 19 and discharge gutter 13 are used for switching.

In FIG. 4, instead of the switching valve 19, a take-out gutter 21 which can be freely entered and exited is provided, and the polished rice supplied from the milled rice supply port 2 is supplied to the oscillating rice sorting body 11 or the take-out gutter 2 is provided.
1 is taken out directly.

FIG. 5 shows that when the length of the oscillating rice sorting body 11 is modified and the oscillating rice sorting body 11 is positioned below the white rice supply port 2, the oscillating stone removal sorting plate 5 is removed from the oscillating rice sorting body 11. When the oscillating rice sorter 11 is removed, the rice is taken out to a receiving gutter 12 and a discharging gutter 13.

(effect) Next, we will discuss the effect.

At the beginning of the work, there will be a lot of brown rice 16, so
The switching valve 19 is kept in the position shown by the solid line in FIG. 1, and in this state, grains are supplied from the polished rice supply port 2. Then, via the switching valve 19, the rice receiving gutter 12 and the discharge gutter 1 are
3, so it can be taken out of the system.

As the work progresses, only the polished rice 17 will be supplied from the polished rice supply port 2, so the switching valve 19 is switched to the position shown by the temporary line. Then, the oscillating rice sorter 11
The milled rice is sorted by the oscillating millet sorter 11, and the white rice 17 is supplied to the oscillating stone extraction sorting board 5.
The grains are taken out from the grain outlet 6, and the stone chips are taken out from the stone chip removal section 7.

In FIGS. 2 to 5, the flow path can be switched by switching the switching valve 19 to the position shown by the solid line and the position shown by the phantom line.

(Effect) The conventionally known one is a rice miller a with a feeding elevator b.
A switching valve d is provided between the rice milling machine a and the stone removing machine c, a return path f is provided between the switching valve d and the loading port e of the supply elevator b, and a switching valve d is provided between the switching valve d and the stone removing machine c. A supply path h was provided between the supply section g and the measuring device j was supplied via the elevator i.

In the known method, a switching valve d is provided between the rice polishing machine a and the destoning machine c, and the switching valve d is returned to the insertion port e of the supply elevator b via the return path f, and the switching valve d and the destoning machine are connected to each other. Since the supply path h is provided between the supply section g and the supply section g of the supply section c, the configuration is extremely complicated.

However, in the present invention, a polished rice supply port 2 is provided in the upper part of a case 1 of a stone removal machine, and a stone removal device 4 is provided at a lower position inside 3 of the case 1. In a stone removing machine, a flow path leading to the rocking stone removing and sorting plate 5, a flow path leading to the outside of the rocking stone removing and sorting plate 5, and a switching valve 19 therefor are provided between the rocking stone removing and sorting plates 5. Since it is configured as a flow path switching device, simply by switching the switching valve 19 in the case 1 interior 3 of the stone removal machine, the flow path leading to the oscillating stone removal sorting plate 5 and the oscillating stone removal It is characterized by a simple structure and easy implementation.
