Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a hulling and sorting device for deweighing and sorting rice.

Problems to be Solved by the Invention This invention solves the problem of separating and sorting paddy into paddy, brown rice, and small rice after dehulling the paddy using a descaling device. If there are many stubs, it may adversely affect the sorting performance of the sorting device, so the idea is to reduce the supply of such small rice, especially fine rice with no commercial value, to the sorting device.

Means for Solving the Problem The present invention provides a sorting millimeter rice flow path (3) of a sorting device (2) that separates and sorts the scraped rice that is deweighed by a weighing device (1) into paddy, brown rice, and millet rice. A flow meter (4) is installed at the top, and a dust removal fan (6) sucks the wind force from the wind selection passageway (5) located below the scale removal device (1) to wind-select the fallen rice, depending on the flow rate of the rice. The rice hulling sorting device is configured to be adjusted by changing the rotation speed of the rice huller.

Function and Effects of the Invention The fallen rice that has been deweighed by the weighing device (1) falls into the wind sorting passage (5) below, where rice husks, etc. are sorted out by the suction air of the suction dust exhaust fan (6). It is supplied to the post-sorting device (2). In this sorting device (2), the fallen rice is separated and sorted into paddy, brown rice, and small rice, but a large amount of sorted rice, especially fine rice, is sorted and taken out into the rice flow path (3). If this is the case, the flowmeter (4) in the flow path (3) detects this and rotates the dust removal fan (6) to suck up the wind force from the wind selection path (5) below the demixing device (1). Increase your numbers and become stronger,
In this wind return section, a large amount of small rice such as rice grains is sorted and separated in advance and then supplied to the sorting device (2).

Therefore, the sorting device (2) that separates and sorts paddy and brown rice is not supplied with a large amount of these small rices, and does not interfere with the sorting of paddy and brown rice.

In addition, if the amount of small rice in the small rice flow path (3) is extremely small, this is detected by the flow meter (4), and the rotation speed of the suction and dust removal fan (6) is lowered to remove the small rice from the air selection path (5). This reduces the wind force of the fan (6), prevents the brown rice from scattering to the suction/exhaust fan (6), and also reduces the power required.

It is connected to.

The scraped rice that falls from the weighing device (1) is sent to the wind selection passageway (5).
The rice husks, etc. are removed from the machine by the suction dust exhaust fan (6), and the waste rice such as rice husks falls onto the waste rice receiving trough (G), and the mixed rice of paddy and brown rice falls into the falling rice receiving trough. It is collected by the transfer helix αQ and supplied to the relay tank α by the grain lifting device OQ.

The grains in the relay tank αη are supplied to the mixed rice receiving trough ■ and transferred, and then transferred by the feed screw (c) to the starting end 011 (a) of the rotary sorting tube (e), and then transferred from the supply port (c) to the rotary sorting tube. It is supplied to Kanai.

The grains supplied to the rotary sorting tube (1) are divided into barbarians (one grain α) as the sorting tube (1) rotates in the direction of arrow I/1.
However, long-grained rice has a center of gravity located outside the barbarian αO, so it slides down much faster, while short-grained brown rice has a center of gravity within the barbarian Q. Therefore, they are lifted to a relatively high position and fall into the brown rice receiving trough (a), mixed rice receiving trough (a), and rotating sorting tube trough, respectively.

The brown rice that has fallen into the brown rice receiving gutter is transferred to the terminal side (b) by the transfer helix, and is taken out of the machine by the grain lifting device @ through the flow passage gutter and the brown rice receiving gutter (a). .

The mixed rice that falls into the mixed rice receiving trough (c) and is collected is transferred to the starting end side (a) by the transfer helix (c) and then transferred to the supply port (c).
It is circulated from there into the rotating sorting tube.

The paddy discharged from the rotary sorting cylinder (1) is collected in the unhulled rice receiving trough and is circulated to the reduced paddy supply funnel (, 9) by the grain lifting device (to).

In addition, at the starting end of the rotary sorting tube (1), the rice that fits into the brown rice is lifted further in the direction of the transmission (one) than the brown rice falling position, falls into the rice receiving gutter, and is collected in the rice flow path. It passes through (3) and is returned to the rotary sorting cylinder, but due to the falling blade of the rice, the sensor (to) of the flowmeter (4) is rotated against the spring (to) to center around the rotating shaft. The flow rate is detected by a potentiometer.

The test value of the potentiometer ω of the flowmeter (4) is compared with the output of the Xiaomi flow rate reference value setter θη in a comparison calculation circuit (foundation), and if the Xiaomi flow rate is higher than the reference value, the amplifier θ is The signal is outputted to the drive circuit (7) through the motor to rotate the forward/reverse motor (g) in the normal direction. Therefore, the forward/reverse motor (

Therefore, the fallen rice that falls into the sorting air passage (5) is sorted by a strong suction wind, and small rice, stubs, etc. are sucked in advance and collected in the waste receiving gutter (G). ) is not supplied with extra rice.

On the other hand, when the amount of rice is less than the reference value, it is outputted from the comparison calculation circuit (product) to the drive circuit (2) via the amplifier 61 to reverse the forward/reverse rotation motor (product). Therefore, the support rod (C) is rotated in the opposite direction of the arrow by the output shaft of the forward/reverse rotation motor, and the pressing force on the belt (3'J) is weakened by the tension pulley 0]). The rotational speed of the suction and dust removal fan (6) is lowered to weaken the wind force in the sorting air passage (5).

Although the rice collected in the rice receiving trough (a) is configured to be returned to the rotary sorting tube (1), it may be taken out of the machine using the downflow trough.

Further, the embodiment shown in FIGS. 4 and 5 is a rotary sorting device (2
