Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention relates to a grain sorting device for sorting mixed rice of paddy and brown rice using a rotating sorting tube having a large number of potholes on its inner circumferential surface. It is something.

(Prior art) A rotary sorting tube with many potholes on its inner circumferential surface.
There is a hulling machine that sorts the mixed rice of Mohijin brown rice. In this conventional device, the shedding rate of the fallen rice that has been slipped off in the shedding section,
It is not structured in relation to the grain flow regulation of the grain to be sorted in the rotary sorting cylinder to the discharge side, and if the hulling rate is low, the paddy will be inside the grain to be sorted in the rotary sorting cylinder. Because of the relatively large amount, the flow toward the discharge side tends to stagnate, which may cause clogging of grains.Also, if the hulling rate is high, the grains to be sorted in the sorting cylinder in one rotation tend to stagnate. Since there is a large amount of brown rice in the grains, there are fewer grains on the discharge side of the single-rotation sorting cylinder, and the grains to be sorted flow quickly toward the discharge side, resulting in the problem of double rubbing of brown rice. (Means for Solving the Problem) This invention attempts to solve the above-mentioned problems, and the technical means of this invention to solve this technical problem is to Grain troughs (14) and (16) for receiving the grains sorted by the rotary sorting tube (11) are arranged in the rotary sorting tube (11), which has a large number of pot holes. Grain gutter (14) on the discharge side of the tube (11)
)・ A discharge control device (28) is installed below (18), and the discharge is carried out when a low shedding rate is detected by the shedding rate sensor (30) that detects the shedding status of the dropped rice in the shedding section (1). The control device (28) is configured to be adjusted to the small control side, and the discharge control device (28) is adjusted to the large control side when a high pulp removal rate is detected.

(Operations and Effects of the Invention) When the shedding rate of the fallen rice in the shedding section (1) is high, the discharge regulating device (28) is positioned on the side that greatly restricts the flow of grains, and the Since the flow of grains to be sorted in the sorting tube (11) to the discharge side is restricted, it is difficult for the brown rice to flow to the discharge side, reducing the amount of brown rice returned to the husking part (1), and reducing the amount of brown rice that is In order to reduce the damage to the grains due to the rubbing phenomenon, and when the shedding rate of the scraped rice in the threshing section (1) is low, the discharge regulating device (28) is set to the side that restricts the flow of the grains to a small extent. The rotary sorting tube (11) is located at the top of the rotary sorting tube (11) to ensure a good flow of grains, thereby preventing the grains to be sorted from clogging and allowing efficient grain sorting work. .

Next, the operation of the embodiment will be explained. When carrying out hulling work, the raw rice is supplied to the tank (2), and each rotating part of the hulling machine is driven. Then, the paddy tank (2) is removed from the paddy tank (2).
The paddy supplied to 1) is subjected to a dehulling action, the scraped rice is sorted in the lower scraped rice wind sorting path (4), and the rice husks are discharged outside the machine from the dust exhaust pipe (6).Brown rice The mixed rice and paddy fall into the sliding rice receiving trough (7), and are lifted up and supplied to the starting end side of the supply trough (14) on the side of the rotary sorting cylinder (11) by the mixed rice lifting machine (8), The supply helix (13) in the supply gutter (14)
1) is supplied to the supply side end.

Next, the mixed rice is scooped up by the pot hole of the rotary sorting tube (11) which is rotating clockwise in Figure 2, and the fine brown rice falls into the finishing rice gutter (16), and the paddy and some brown rice are removed. The mixed rice falls into the supply gutter (14) and is sorted, and the unsorted mixed rice that falls into the feed gutter (14) is sorted by the feed helix (14).
In step 3), the material is supplied from the transport end of the supply gutter (14) into the rotary sorting tube (11) again and is re-sorted. In addition, the finished rice that has fallen into the finishing rice gutter (16) is conveyed to the finishing rice flow down tube (17) by the finishing rice helix (15), and is transferred to the finishing rice flow down tube (17).
) while falling to the finished rice receiving trough (19), it is sorted by a sorting wind and taken out of the machine by the finished rice fryer a (20).

The paddy sent to the discharge side end of the rotary sorting cylinder (11) enters the adjacent paddy lifting cylinder (21),
1), falls into the upper paddy return channel (22), is returned to the phushulling section (1), and is subjected to the phushuping action again in the phushulling section (1).

The hulling and sorting work is carried out as described above,
When the shedding rate sensor (30) becomes below the predetermined shedding rate,
The signal output from the comparator (32) is sent to an OR circuit (33),
It is sent to the solenoid (34) via the drive circuit (38), actuates the solenoid (34), and adjusts the flow of the grains toward the discharge side of the discharge regulating device (28) to a small level.
It facilitates the flow of the grains to be sorted in the rotary sorting tube (l l) to the discharge side, speeds up the return of the unhulled rice to the husking section (1), and improves the flow of the grains in the rotary sorting tube (11). This prevents clogging phenomenon. Additionally, when the plow removal rate sensor (30) detects a plow removal rate higher than a predetermined plow removal rate, the output signal from the comparator (32) stops, the solenoid (34) becomes inactive, and the emission control As shown by the solid line in Figure 4, the parts (2, 8) are in a state where the flow of the grains to be sorted in the rotary sorting tube (ll) toward the discharge side is greatly regulated, and the brown rice is removed from the discharge side end. This prevents the rice from being reduced to the pube (1), prevents the double-sanding phenomenon of brown rice, and prevents damage to the grains.

In addition, when the discharged grain detection sensor (37) detects grains below a predetermined amount, a limit switch is activated and the solenoid (34) is activated via the OR circuit (33) and the drive circuit (38).
), the discharge restrictor (28) is adjusted to the side that reduces the restriction, and the zero-rotation sorting tube (11) facilitates the flow of grains to be sorted in the rotary sorting tube (11) to the discharge side. When the amount of grains on the discharge side of the inner
1) causes a waving phenomenon in the grains that are scooped out, reducing the sorting efficiency, but this phenomenon can be prevented.
