Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rotary sorting device that is integrated with a huller and separates mixed rice into paddy and brown rice.

[Prior art]

The finishing valve of the brown rice transfer gutter located inside the rotating sorting tube is composed of a single plate extending from the grain supply side to the discharge side of the sorting tube, and is used to control the proportion of paddy mixed into the recovered brown rice, etc. Adjust the rotation while watching.

Furthermore, the amount of paddy supplied to the shedding section can be changed in size by operating the efficiency lever, but this is independent of the rotational adjustment of the finishing valve.

[Problem to be solved by this invention] For example, if there is a large amount of paddy mixed in the recovered brown rice, if the finishing valve is rotated upward and the brown rice intake position is changed to a higher position, the amount of paddy mixed in will be reduced. In this case, since the finishing valve is made up of a single plate, efficiency is lost on the grain supply side where a large amount of brown rice is scooped out, and the brown rice to be collected tends to flow to the discharge side and is returned to the shedding section.

This causes so-called skin slippage. In addition, if the finishing valve is maintained to ensure the amount of brown rice recovered on the supply side, when the amount of mixed rice in the rotary sorting cylinder decreases, especially on the discharge side, it will become mostly a paddy layer, so paddy will be mixed into the recovered brown rice. There is a simple drawback.

In addition, if the finishing valves are simply divided and their rotations are adjusted independently, it is not easy to adjust them, especially the discharge side finishing valve.

[Means to solve the problem]

This invention attempts to eliminate the above-mentioned drawbacks, and is it the next technical means? I gave a lecture.

That is, in a rotary sorting device that collects the brown rice into the brown rice transfer gutter α while scooping up the mixed rice supplied to the rotary sorting tube 011 at the inner circumferential pile (10QO...), the brown rice transfer gutter 04 is connected to A finishing valve VcFf that can be rotated and adjusted independently by a plurality of divided bodies from the grain supply side to the discharge side of the rotary sorting cylinder is formed, and among these divided finishing valves αGα, the finishing valve on the grain discharge side is The rotary sorting device is configured to rotate in conjunction with an efficiency lever that changes and adjusts the amount of paddy supplied to the shedding section.

[Operation and effect of the invention]

The mixed rice supplied into the rotary sorting cylinder is scooped up in large piles, and the brown rice is collected into the brown rice transfer gutter after passing through the dividing finishing valve.

The amount of rice supplied to the shedding section can be arbitrarily changed in size by operating the efficiency lever, and the amount of mixed rice in the rotary sorting cylinder increases or decreases accordingly. When the amount of mixed rice in the rotary sorting cylinder is large, the amount of brown rice is also large, and the split finishing valve should be set (rotated) at a low position to increase the efficiency. In particular, since the amount of brown rice is extremely small on the discharge side, the grain intake position of the discharge side finishing valve should be set at a high position to reduce the amount of paddy mixed into the brown rice transfer gutter. When the amount of paddy supplied to the shedding section is large in conjunction with the efficiency lever, it rotates downward and the grain intake position becomes low.
On the other hand, when the amount is low, it is set to a high level, so special operations by changing the size of the amount of mixed rice are not required, and problems such as paddy mixture in brown rice or unevenness of the skin are reduced. In addition, on the supply side of the rotary sorting cylinder, there is a sufficient amount of brown rice regardless of the change in the amount of mixed rice in the longitudinal axis, but the finishing valve on the supply side always takes in brown rice regardless of the movement of the finishing valve on the discharge side or the efficiency lever. It is convenient because the optimum position can be secured.

〔Example〕

An embodiment of this invention will be described based on the drawings.

(1) is a shedding part, which includes a paddy supply funnel (2), a pair of shedding rolls (31 (3), etc.).A dust exhaust air passage (4) is formed below the shedding part (1). Then, the rice husks mixed in the extracted rice are discharged out of the machine via the dust exhaust pipe (6) by the suction fan (5).

The structure is such that paddy etc. are accumulated downward from the middle of the air path (4).

The washed out mixed rice of paddy and brown rice falls into the lower receiving trough (7). 6 (8) is a grain lifting machine connected to this.

(9) is the sorting machine frame, and inside there are many stacked 0
A rotary sorting cylinder α11 having numbers 001, . . . is rotatably provided on a horizontal axis. In addition, a mixed rice transfer gutter ■ is installed in this machine frame (9) with an open top surface to be located inside the rotary sorting cylinder D, and the terminal end opening of the grain lifting machine (8) is connected to the starting end side of the mixed rice transfer gutter ■. Look at the rotating sorting cylinder 01 with the transfer spiral αJ.
The configuration is such that mixed rice is fed and transferred to the supply side of No. 1 (the rear side of the machine frame (9)).

A< is a brown rice transfer gutter installed parallel to the mixed rice transfer gutter @, which is equipped with a transfer spiral α9 and is connected with a finishing valve αGαη whose angle can be freely adjusted.

The above-mentioned finishing valve is divided in the longitudinal direction from the supply side to the discharge side of the rotary sorting cylinder αυ (in the example shown, it is divided into two parts), and is divided into a wide finishing valve αG on the supply side, and a paddy reducing machine groove section, which will be described later, with a slight middle part. Discharge side finishing valve Q71 with cutout part formed to prevent interference
It consists of (to) is a shaft that supports both finishing valves α0αη, the supply side finishing valve αG is constructed integrally with this shaft (to), and the discharge side finishing valve αη is loosely fitted and configured to freely rotate. be.

In addition, the mixed rice is scooped out by the volume αOQO of the rotary sorting cylinder αB and separated into paddy and brown rice, of which the brown rice is transferred to the transfer gutter by passing over the finishing valve aOα71. It is.

The discharge side of the brown rice transfer gutter α4 communicates with the brown rice flow down tube 01. A grain board is visible below this flow tube 09 to guide the brown rice into the brown rice gutter QD. The kan is a grain frying machine.

On the discharge side of the rotary sorting cylinder OD, an annular body @ is arranged in series to rotate integrally, and on the inner peripheral surface of this annular body, grain lifting blades (c) (c) are placed at predetermined intervals.・ is provided to scoop up the paddy mixed with unrecovered brown rice that has reached the discharge side of the rotating sorting tube αυ. (to) is a reducing hole that opens on the front side of the sorting machine frame (9), and corresponding to the width of this reducing hole, there is a slanted reducing gutter that receives the above-mentioned paddy etc. that is scooped out by the grain lifting blades @4 @41... A kimono is provided. In addition, the supply funnel (2) of the removal part (1)
) is an opening that is joined to the front surface of the sorter frame (9), and the rice grains etc. flowing down from the inclined reduction seed @ are directly returned to the supply funnel (2).

The gradient is a layer thickness sensor that hangs down to rotate according to changes in the layer thickness of the mixed rice supplied to the rotary sorting tube QDK. When the supply valve C3 provided in the section is interlocked with opening and closing, when the layer is thick, swing the rocking plate around the axis to reduce the supply amount, and when the layer is thin, do the opposite. This is a technique to increase the amount of supply by shaking it.

Further, the swing plate is swingable around its axis by operating a manual efficiency lever.

A wire (to) is connected between the substrate (38a) of the efficiency lever (to), which can arbitrarily change the supply amount, and the discharge side finishing valve α force of the split finishing valve, and the efficiency lever (to) is connected. When moving upward to reduce efficiency, the discharge side finishing valve αq is rotated upward to set the grain intake position to a high position; conversely, when increasing efficiency, it is rotated downward to lower the grain intake position. We will develop it as soon as possible.

(to) is an adjustment lever, which is connected to the spindle (to) of the finishing valve αUη, and can adjust the angle of the supply-side finishing valve αG as desired.

(9) is the roll that comes off (3) (31, suction fan (5),
This is a motor that drives each rotational sorting section, grain transfer section, etc.

The action of the upper side will be explained.

When the motor @ is started and paddy is supplied to the paddy supply funnel (2), the paddy is removed from the roll (31) according to the supply valve 01 (6 paddy that falls between 31 is removed, and the rice that has fallen off is discarded). As the dust flows down through the wind channel (4), it is screened and the rice husks and grains are separated.

The mixed rice of paddy and brown rice is supplied to the mixed rice transfer gutter α2 of the rotary sorting section through a receiving gutter (7) and a grain frying machine (8). It is sequentially transferred by the action of the transfer spiral and reaches the supply side of the rotary sorting tube αυ.

The rotating sorting cylinder αD rotates in a fixed direction, and the pot hole 0001...
・Scoop up the mixed rice. Brown rice is in this pot hole 00 QO・
··in.

It rises to a high position, passes over the finishing valve αG or αη, and falls into the brown rice transfer gutter 04. Similarly, for rice, the pot hole α0αO
... tries to scoop it up, but it is a long grain.

In addition, since the center of gravity is high, the pot falls off from the hole QO (10...) at a low position, flows down into the rotating sorting tube αB, or falls into the mixed rice transfer gutter υ, and returns to the rotating sorting tube α.
B is returned to the supply side. This sorting action is repeated from the supply side to the discharge side of the rotary sorting tube αD to separate paddy and brown rice. The brown rice is collected outside the machine through the brown rice flow tube.

On the discharge side of the rotary sorting cylinder 0D, paddy and unrecovered brown rice remain, but they are scooped up by the grain lifting blades @ (A) on the inner circumferential surface of the annular body QD and rise, and are reduced to grade-reduced seeds ( ) and flows down to the Kankan Kanhan side. Passes through the reduction hole. It gets mixed into the original state, and then the process of removing it again, wind sorting, and rotating sorting is repeated.

By the way, among the 1-split finishing valves QG (Q7), the supply side finishing valve αG can be arbitrarily set to an appropriate angle using the adjustment lever side, and the discharge side finishing valve α is linked to the adjustment of the efficiency lever (to). Rotate. That is, as the efficiency lever 03 is raised to reduce the opening degree of the supply valve 01) and the amount of paddy supplied to the shedding section (1) is reduced, the discharge sidewall and the valve αη are
is rotated upward to set the grain intake position to a high position. When the opening degree of the supply valve 0'D decreases, the amount of mixed rice supplied into the rotary sorting tube αD also decreases, and on the discharge side of the sorting tube αD, the proportion of brown rice mixed is extremely low, and the paddy is removed from the pot hole Ql). ... to scoop up the rice to a high position, but the discharge side finishing valve α automatically rotates upward, raising the grain intake position and reducing the chance of paddy jumping into the brown rice transfer gutter α4.

Conversely, when the efficiency lever (to) is lowered, the opening degree of the supply valve I3υ becomes large, and the finishing valve αη on the discharge side is rotated downward, thereby lowering the grain intake height. Therefore, even if the amount of mixed rice in the rotary sorting tube αυ increases and the amount of brown rice on the discharge side increases, it can be collected along the brown rice transfer gutter α, and the so-called double-polishing that redistributes brown rice can be avoided. 4 phenomena can be reduced.

In this embodiment, the finishing valve is divided into two parts, but it may be divided into more parts.
