Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a swing sorting automatic adjustment device in a rice hulling sorting device.

In other words, in a hulling sorting device that is constructed by connecting a husking machine with a oscillating sorting plate having a grain selection plate whose inclination can be adjusted freely, the rice removed by the hulling machine is detected by a color sensor, and the paddy is separated. The inclination of the grain sorting plate of the oscillating sorter can be adjusted according to the state of grain contamination, and the oscillating sorting can be adjusted in a good manner so that the oscillating sorting can be carried out in the best condition according to the state of removal. The present invention provides a simple structure that can be easily implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows the main parts of a hulling and sorting device, where A is a hulling machine, in which a movable rubber roll 2 and a fixed rubber roll 3 are arranged side by side in a dechamber 6 below a hopper 5 so as to be freely reversible. Beneath the reflecting plate 7 between the rubber rolls 2 and 3, inverted V-shaped drift plates 8 and 9 are provided diagonally, and a sorting air passage 1 is provided diagonally below the grain plates 8 and 9.
A suction port 12 of a suction dust ejector 11 is connected to the upper side of the 0, and a part of the grain discharging plate 4 with a gentle slope installed on the lower surface of the sorting air passage 10 is connected above the part on the lower side of the slope. It is equipped with a color sensor S that can detect when the amount of rice inside increases.

B shows the entire swinging sorter, in which a large number of grain sorting plates 1 having rough surfaces on the upper surface are stacked together, and the lower part is mounted on swinging supports 13, 13, 14, 14, and installed on the upper side of each grain sorting plate 1 in the longitudinal direction Y-inclined, is equipped with a supply tank 15 so that removed rice can be supplied from below the grain flow plate 4 in the hulling machine A. A brown rice gutter 1 is installed outside the end of each grain sorting board 1 on the Y-slanted side in the vertical direction.
6. A mixed rice gutter 17 and a paddy gutter 18 are installed in parallel, brown rice is taken out from the brown rice gutter 16, mixed rice in the mixed rice gutter 17 is returned to the supply tank 15, and the paddy gutter 1
The paddy No. 8 is returned to the hopper 5 of the huller A, and the structure is similar to the conventional type.

Further, one of the swinging supports 13 includes a swinging rod 19.
are connected to each other so that each grain sorting plate 1 can be swung laterally, and a support shaft 20 connected between the lower portions of the other two swing support rods 14, 14 has two inclined operation rods 21,
The upper part of 21 is connected freely to rotate, and the metal 22, 2
A double female screw body 2 that is screwed into a threaded rod 23 that is axially mounted on the screw rod 23.
The lower parts of the operating rods 21 and 21 are connected to the lower portions of the operating rods 21 and 24 so as to be freely rotatable, and the threaded rod 23 and the shaft 25 of the drive motor M are connected through a joint 26, so that when the motor M is started, the operating rods 21 and 21 are connected to each other. 21 is tilted and the swing support rods 14, 14 are moved up and down to change the inclination of each grain sorting board 1 in the lateral direction X.

The motor M is a forward/reverse motor, and the motor M and the color sensor S are connected to a control box C so that the motor M can be driven in the forward and reverse directions based on a detection signal from the color sensor S.

Therefore, during work, the removed rice removed by the huller A is removed from each grain sorting plate 1 in the oscillating sorter B.
When the flow is carried out in the vertical direction Y, the horizontal direction
The brown rice is swung to the upper side of the slope in the horizontal direction X, and the mixed rice is separated in the middle, and the brown rice is sent to the brown rice gutter 16 and the mixed rice is transferred to the mixed rice gutter 17.
Further, the paddy falls into the paddy trough 18 and is processed.

In this state, the color sensor S detects the removed rice flowing down on the grain grain board 4 in the huller A and sends a detection signal, which starts the motor M and moves the grain selection board 1 in the horizontal direction X. The slope will be changed, but if the rice is in good condition and there is little paddy mixed in during shedding, the horizontal slope of the grain sorting plate 1 will be loosened, whereas if there is a lot of paddy mixed in, the horizontal slope will be changed. can be made sudden, thereby making it possible to carry out oscillating sorting according to the release state.

As described above, the present invention provides a separate hulling machine device comprising a oscillating sorter having a grain sorting plate whose inclination can be adjusted freely and is connected to a hulling machine, in which grain removal is carried out by both rubber rolls in the hulling machine. A color sensor capable of detecting the mixed state of paddy is installed on the grain board through which the wind-sorted rice flows, and the detection signal from the color sensor is used to change the inclination of the grain selection board in the oscillating sorter. Since the drive motor is equipped to start and control, the color sensor detects the removed rice from the huller and changes the inclination of the grain selection plate of the swing sorter depending on the state of paddy mixture. It has the advantage of being able to carry out dynamic sorting, being able to automatically adjust the oscillating sorting to be carried out in the best condition depending on the state of removal, and being able to be suitably implemented with a simple structure.
