Abstract

PURPOSE:To obtain an ideal huller by opening a shutter when there is an appropriate amt. of unhulled rice having a water content below the set value in a tank, approaching a roll when the shutter is opened, closing the shutter and opening the roll when the unhulled rice of high water content is supplied in hulling. CONSTITUTION:The water content of the unhulled rice in a feed hopper 3 is measured by a meter 35, and a shutter 4 is immediately closed when the water content is increased above a set value. When the fact that the water content is below the set value is sensed by the meter 35 and the lower-limit level switch 18 of a feed tank 9 is turned on, a tank sutter 12 is opened, and the unhulled rice is supplied to a hulling part 25. When the upper-limit level switch 17 of the tank 9 is turned on, the shutter 4 is closed. When the supply of unhulled rice to the hulling part 25 is sensed by a sensing plate 24, an auxiliary roll 22 is approached, and hulling is carried out. When the water content of the unhulled rice supplied to the hulling part 25 is increased above the set value in hulling, the shutter 12 is closed, and the auxiliary roll 22 is separated.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the one disclosed in Japanese Patent Publication No. 159139, a moisture meter 20 is attached to a supply tank of a hulling device, and a shutter 13 for changing an opening degree based on a moisture value detected by the moisture meter 20 is attached to a lower portion of the supply tank. This is a hulling method in which the removal rate is always constant even if the water content of the supplied paddy changes, but when the water content is large, the hulling is difficult, and therefore the purpose is not achieved. In addition, the conventionally known JP-A-61
In the one described in Japanese Patent No. 50645, a moisture detecting sensor B capable of detecting moisture of paddy rice is attached to a lower position of the roll, and the moisture of the paddy rice that has been hulled is measured. The shutter 5 is closed by and the auxiliary roll 2 is separated by the motor M2.
It is too slow to control by measuring the water content of hulled rice. Further, although it is described that the work is started in a state where the main and sub rolls 2 and 3 are in contact with each other, the specific contact technique of the main and sub rolls 2 and 3 remains unsolved. Also,
The one disclosed in the conventionally known Japanese Utility Model Laid-Open No. 58-19749 uses the level sensor 1 attached to the tank 7 to
This is a technique of opening and closing the shutter 2 and bringing the level sensor 1 into and out of contact with the auxiliary roll 4, but there is no description regarding the relationship with the water content of the paddy rice. That is, ideally, the shutter opens when the amount of paddy in the tank is less than or equal to the set moisture and an appropriate amount, the roll approaches when the shutter opens, and if the paddy with a lot of water is supplied during the hulling process, the shutter will be released. It should be closed and the roll should open.

[0008]

[Operation] Next, the operation will be described. Describing based on the flowchart of FIG. 2, since the supply tank 9 is empty and the lower limit level switch 18 is off before starting the work, the motor 27 is driven to rotate the supply belt 26, and the hopper shutter 4 is turned on. It is opened and dropped onto the supply belt 26. The dropped paddy moves up the supply elevator 1 and is supplied to the supply tank 9.

The moisture content of the paddy rice in the stake hopper 3 is measured by the moisture meter 35, and when the moisture content is equal to or higher than the preset moisture content, the hopper shutter 4 is immediately closed. When the moisture meter 35 senses the set moisture or less and the lower limit level switch 18 of the supply tank 9 is turned on, the tank shutter 12 is opened and the moisture is supplied to the hull portion 25. When the upper limit level switch 17 of the supply tank 9 is turned on, the hopper shutter 4 is closed.

When supplied to the paddy hull 25, the paddy sensing plate 24 senses this, hulls the pad by bringing the auxiliary roll 22 into contact, and the paddy is sucked and removed by the suction blower 29.
Sorting is performed by the sorting unit 28.

During the hulling operation, when the water content of the hull supplied to the hulling portion 25 exceeds the set water content, the tank shutter 12 is closed and the auxiliary roll 22 is separated.

[0012]

Ideally, the shutter opens when the amount of paddy in the tank is less than or equal to the set water content and an appropriate amount, and when the shutter opens, the rolls approach, and if the paddy with high water content is supplied during hulling. It is good that the shutters close and the rolls open. However, according to the present invention, the tension hopper 3 having the hopper shutter 4 and the moisture meter 35,
The paddy hopper 3 supplies paddy to supply upper and lower limit level switches 17 and 18, a moisture meter 36, and a tank shutter 1.

When the total amount 35 detects less than the set water content and the lower limit level switch 18 does not detect the paddy, the upper limit level switch 17 opens and closes when the paddy is detected.
Further, the tank shutter 12 of the supply tank 9 is manually opened, but it is closed when the moisture meter 35 of the inflating hopper 3 detects that the moisture content of the paddy is equal to or more than the set value, and the auxiliary roll 22 of the paddy hull portion 25 is also closed. Is a hulling device that comes into contact when the hull sensing plate 24 detects that hulling has been carried out by the hulling portion 25 and separates when the hull sensing plate 24 stops sensing. The water content of the paddy rice is measured by the water content meter 35. When the water content is above the set water content, the hopper shutter 4 is immediately closed, the water content meter 35 detects the water content below the set water content, and the lower limit level switch 18 of the supply tank 9 is turned on. When the upper limit level switch 17 of the supply tank 9 is turned on, the hopper shutter 4 is closed to open the tank shutter 12 and supply it to the hulling section 25. When paddy water supplied to become more than the set water closes the tank shutter 12, by separating the sub-roll 22, it is rice sliding of the ideal.
