Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a receiving gutter device for a rotary grain sorter, and particularly to a receiving gutter device for a rotary grain sorter.

Conventionally, a rotary grain sorting machine has a rotatable sorting tube with many recesses and a catch gutter inside, and while the sorting tube is slowly rotated, a mixture of paddy and brown rice is collected from one end of the tube. supply,
The mixture flows in the axial direction inside the sorting tube, and in the middle of the flow, the mixture tries to be scooped up as the sorting tube rotates, but the brown rice sinks and gets stuck in the recess and is lifted upwards. Then, it falls in a large parabola. On the other hand, the paddy is also scooped up, but because it does not fit into the dent, it falls in a small parabola. A catch channel is installed at the point where the brown rice falls, so the paddy and brown rice are separated.

On the other hand, the sorting performance depends on various factors, and favorable results can only be obtained experimentally, but according to the inventors,
Good results were obtained when the sorting tube was hung horizontally. However, since the mixture is supplied from the end of the tube, the mixture accumulates on the supply side and becomes bulky, and the inside of the sorting tube gradually expands as it goes towards the end, making the number of layers constant. Therefore, the sorting action is performed in the best condition in the sorting tube. Therefore, since the mixture becomes bulky on the supply side, J'4. J I-" Nigesaku IJj + met with active, and i" J also jumped into the receiving gutter:, causing deterioration of sorting performance.The supply of the sorting tube that was cut was opposite to 4iQ! Output of J+11 E At the mouth, the amount of ligated material decreased, and even there, one or more particles were easily crushed, reducing the sorting performance.

Therefore, it is an object of the present invention to make improvements in response to f%i and to eliminate the problems of the prior art described above.

Embodiments of the present invention will be described below with reference to the accompanying drawings. Figure 1 shows a cross section of the entire rice huller, and the cold husking machine A has a rice huller C placed on one side of the soil surface of the wind sorting part B, which is a rectangular box, and rotates side by side with this. A sorting machine is mounted and the whole is constructed (/-I).

Wind sorting department BIF-ba, No. 2 conveyor 1, mixed rice conveyor 2
, 3 brown rice conveyors are installed in parallel. Since the wind sorting section B is provided with a suction dust extractor 4 at one end K in the longitudinal direction, and an intake port 6 is provided at the other end in the longitudinal direction, each of the conveyors 1.
2.3 The sorting wind is made to flow in the direction shown by the broken line.

The hulling section C has a pair of rolls 9 inside, and 7) throws a dropper] 0 upwards.

The rotary sorting machine D (has two upper and lower sorting tubes 1.I'l suspended horizontally in a box-like case 14. The axial direction of these sorting tubes 1.H is just opaque. It is arranged to be perpendicular to the axis of the release roll 9 in the sliding portion 01C.The sorting cylinders 1 and II have hemispherical recesses 15 of a size that allows brown rice to fit therein. A large number of brown rice receiving containers IJi 17 having a substantially V-shaped cross section are inserted and suspended inside the sorting tube 1.TI.

A load conveyor 18 is housed in the receiving trough 17.

Separately from the receiving gutter 17, an upper trunk screw conveyor 19 is arranged in parallel to the upper sorting cylinder 1. The rice hulling section c IQII of the screw conveyor 19 has the same stopping force as the mixing rice slot '7-
The upper end of the tank 12 communicates with the tank 12 via a provision tank 12.

The lower sorting tube ■ communicates with the end of the receiving gutter 17 in the sorting tube I, and further sorts brown rice grains etc. that have been sorted in the sorting tube 1.

Since the structure is as described above, the operation using this rotary sorting and hulling machine is as follows: When paddy is fed to the hopper 10 (this example is a small and portable one, the paddy bags are The paddy/brown rice mixture is removed by the huller C, and the mixture of paddy and brown rice is screened in the wind sorting part B, falls onto the mixed rice conveyor 2, and is fed by the mixed rice thrower 12. The upper barrel screw conveyor 19 transports the upper sorting tube I in FIG.
After being transferred to the right end of the tube, it is supplied to the inner surface of the sorting tube I.

Since the sorting tube I is rotating, the mixture is piled up on the inside of the sorting tube I and is about to be scooped up, but the brown rice is stuck in the dent and is lifted up to ffJy (comparison). While drawing a parabola, the paddy falls down the receiving trough 17Vc, which will be explained in detail later.The paddy is also scooped up, but falls again onto the inner surface of the sorting tube I, and is returned to the omper 10 from the left end of the sorting tube I.

On the other hand, the receiving gutter 171' of the sorting tube I? ; Fallen brown rice etc. are transported to the screw conveyor 18r, l:l:1 in the receiving gutter 17.
From the terminal end, the brown rice is sent to the lower sorting tube (2), and the unpolished rice containing some paddy is again subjected to the same sorting action as the upper sorting tube (1) in the lower sorting tube (2), where it is carefully selected.

The paddy that was not scooped up in the sorting cylinder B (some brown rice is mixed in) is again supplied to the mixed rice conveyor 2. On the other hand, the brown rice that has not been scooped up by the sorting cylinder ■ falls onto the brown rice conveyor 3 while being subjected to the wind sorting action, and is carried out of the machine.

Here, in particular, the present invention is provided with a sorting control valve 22 as shown in FIG. 2, which allows the sorting tube 1 or (2) to scoop into the receiving gutter 17, and its details are configured as shown in FIG. 3. are doing.

Sorting tube I (Also, by rotating the mixture supplied by Y (2nd ``4'' of the sorting tube) in the direction of the arrow, the inner circumferential surface of 71J tube 1 is moved to the left. As the mixture flows, it becomes bulky and piled up, and is scooped up by being scooped up by the inner circumferential surface.At the time of supply, the mixture is more deposited on the inner circumferential surface, so the scooping action is as follows: Both brown rice and paddy are being actively processed, and the upper part of the sorting tube 1 is
It is held until the mouth (I is the brown rice that fits in the dent, and the mouth is the parabola of paddy/brown rice that does not fit in the dent). Next, when the axial direction of the sorting tube I reaches the middle, the amount of the mixture reaches the designed normal amount, and the piled up state becomes a constant spread, so that the brown rice stuck in the recess 15 provided in the sorting tube I is removed. It is lifted higher and falls into the receiving gutter 17 in a parabola. Sorting tube I! I! Near the end, the amount of the mixture decreases and the layer becomes thinner, so that the paddy is also fitted into the recess 15VC and can be scooped up, increasing the mixing of the paddy.

However, the receiving gutter 17 is provided with a pair of receiving side plates 20 and a receiving collecting plate 21 that extend obliquely upward, and the sorting adjustment plate 22 is extended by a 6N vertically adjustable number. and the third fffi,
As shown in the axial plane of the sorting joint 1, the bends 23 and 24 are provided at the W part, so the 1' point scooped up by the inner surface of the sorting cylinder 1 at the time of supply σiz draws a parabolic mouth. However, it was blocked by the bend 23, and the receiving gutter 1
7VC does not fall. In the area where the designed normal layer is formed, only the unpolished rice with a depression of 15 VC is scooped upwards, and as it approaches the end of the sorting tube I, which draws a parabola that falls into the receiving trough 17, the paddy Both brown rice can be lifted higher, but they are blocked by the bent 24VC and do not fall into the receiving gutter 17.

Depending on the increase or decrease in the amount of mixture continuously flowing in from the hopper 10, the difference in shape due to different types, the size of grains, etc., the scooping effect of the sorting tube I (I) may fluctuate, resulting in normal Even if the layer is thick, some i′υ may flow into the receiving gutter 17, or conversely, some brown rice may not reach the receiving gutter 17 and repeat its rise and fall in the sorting tube I together with the handle. If the sorting adjustment plate 22 no longer fulfills its role, the support shaft 25 wound around the base of the adjustment plate 22 can be operated from outside the machine to adjust the upright angle of the adjustment plate 22. Modify as shown in the chain line in Figure 2 to improve the sorting performance.

In summary, the present invention has a sorting cylinder with a large number of recesses formed on its inner peripheral surface, which is rotatably installed horizontally horizontally, and a receiving gutter is installed inside the sorting cylinder to receive the sorted grains scooped up by the recesses. A rotary sorting machine equipped with a rotary sorting machine, in which one end of the sorting node is a supply side of the mixed grains, the other end is a discharge side, and a catch gutter fall prevention member is provided on the supply side and the discharge side of the gutter. Since this is a gutter device, it has the following effects.

- Since the sorting tube is placed horizontally across the IC, the scooping action by the recess is well performed and the sorting performance is good.

■ Even if VC mixed grains are continuously supplied to the sorting tube and the sorting tube is approximately horizontal, the mixed particles accumulate on the supply side and are scooped up by the inner surface of the sorting tube. This prevents the particles from falling into the receiving gutter and preventing them from getting mixed into the sorted particles.

■ Even if the particle layer gets thinner as it approaches the discharge side of the sorting tube and the sorting performance deteriorates, the falling gutter on the discharge side prevents it from falling and does not adversely affect the sorting performance.

■ Since it is simply a material to prevent falling of the gutter, its structure can be easily configured.

FIG. 4 shows another embodiment of the sorting adjustment plate 22, in which the bends 23 and 24 are perpendicular to the surface of the adjustment plate 22, and a bent side plate 26 is attached.
