Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a rotary sorting tube type that sorts mixed rice such as paddy and brown rice using a rotating sorting tube that has a large number of potholes on its inner circumferential surface. This invention relates to a layer thickness detection plate for a grain sorter.

[Prior art]

The layer thickness detection plate that detects the amount of grains to be sorted in the rotary sorting tube according to the conventional technology does not have an inclined surface in the axial direction of the single rotation sorting tube. When grains that do not fall onto the upper grain level fall onto the upper surface of the layer thickness detection plate, they tend to stagnate on the layer thickness detection plate, and as a result, the detection operation cannot be performed smoothly9. Since the grains that have fallen onto the upper surface of the layer thickness detection plate fall from behind in the direction of rotation of the rotary sorting cylinder on the five-layer thickness detection plate, the grains that have been guided to fall onto this flow stack are moves upward due to the rotation of the rotating sorting tube.

The problem is that the grains move as a flow layer below the layer thickness detection plate, and it is incorrectly detected that there is a larger amount of grains to be sorted than the actual flow layer inside the rotary sorting cylinder. There was a point.

[Problem that the invention seeks to solve]

Therefore, this invention smoothly detects the layer thickness by guiding the grains that fall onto the layer thickness detection plate during the rotational sorting operation to the left and right sides based on the rotational direction of the five-rotation sorting tube. This method allows the grains on the plate to fall and also prevents erroneous layer thickness detection.

1. Means for Solving Problem 1) The technical means of the present invention for solving this technical problem is to improve the grain amount 04 of the rotary sorting tube (11), which has a large number of potholes in its inner circumference. ) The rotary sorting tube (11) is supported downwardly so as to be movable up and down, and at least the lower part of the layer thickness detection plate for detecting the amount of grains to be sorted in the rotary sorting tube Qll is connected to the rotary sorting tube (11) in the layer thickness detection plate. Either the supply side end or the discharge side end is configured to be an inclined surface (c) located at the lower side.

〔Effect of the invention〕

According to this technical means, the grains that have fallen onto the layer thickness detection plate during the rotational sorting operation are moved laterally to the right and left with reference to the rotational direction of the rotary sorting cylinder 0υ on the layer thickness detection plate (to). It is guided and dropped quickly, and can make the detection operation of the layer thickness detection plate grain smooth, and can prevent erroneous detection of the amount of grains to be sorted.

In addition, when configuring the 1-layer thickness detection plate (a) IC inclined plane, set either the supply (1111 end or the discharge side end) of the rotary sorting cylinder (11) at the layer thickness detection plate to the L position. , either the discharge side end or the supply side end may be configured as a lower inclined surface.

Next, the operation of the embodiment will be explained. When carrying out hulling work, raw paddy is supplied to the paddy tank (2).

Drives each rotating part of the huller. Then, the paddy supplied from the paddy tank (2) to the shedding section (1) is subjected to the shedding action, and the fallen rice flows into the fallen rice sorting air passage (4) below and is sorted.
The rice husks are discharged out of the machine from the dust exhaust pipe (6). The mixed rice of brown rice and paddy falls into the sliding rice receiving trough (7), passes through the mixed rice supply hopper (9) in the mixed rice grain lifting machine (8), and is transferred to the supply trough ( 14) Starting end (lifted and supplied to tll).

It is supplied to the supply side end of the rotary sorting cylinder (11) through the supply helix 0 in the supply trough 0.

Next, the rotating sorting tube (which is rotating clockwise in Figure 2)
The fine brown rice is scooped up by the pot hole in Ill and falls into the finishing rice gutter 0G F1. Mixed rice of FJ and some brown rice is
The unsorted mixed rice that fell into the supply gutter 04) and was sorted and fell into the feed gutter 0 is fed again into the rotary sorting tube Qll from the conveyance end of the feed gutter 04) at the feed helical 0. Will be re-screened. In addition, 1 tithe - Rice that fell into the rice gutter 00 is served with 0 rice - L rice n, l" m07
), and while falling through the finishing rice flow grain board 081 to the tithe-rice receiving gutter, it is sorted by the sorting wind generated by the rotation of the river breeze fan in the pressure fan chamber, and the tithe-rice grain is Grain is taken out of the machine using the grain handle.

Discharge of the rotating sorting tube On (sorted paddy sent to the till end falls into the lower paddy receiving trough C1), and goes to the paddy tank (2) of the section (1) where the paddy is taken off by the paddy hoist. It is reduced and undergoes the action of shedding again in the shedding part (1).

The hulling and sorting work is carried out as described above.
The increase or decrease of the grains to be sorted in the rotary sorting tube (11) is detected by the layer thickness detection plate, and the shedding part (1) is detected via the layer thickness detection shaft (c) and the interlocking member (not shown). Feedback is sent to the paddy supply control valve @, and the opening degree of the paddy supply control valve (a) is adjusted to adjust and maintain the appearance of the grains to be sorted in the rotary sorting tube (11) within an appropriate range.

In this way, the first layer thickness detection plate moves up and down while in contact with both upper surfaces of the flow stack of grains to be sorted produced by the rotation of the rotating sorting tube (Ill), and detects the amount of grains to be sorted. ,
The upper surface of the layer thickness detection plate (23) is
The grains that have been extracted through the pot holes but do not reach the finishing rice gutter Oe and the supply gutter Oe fall.

The grains that have fallen onto the top surface of the layer thickness detection plate (to) flow down to the bottom of the layer thickness detection plate (to) and also flow along the slope @ slope formed at the bottom of the layer thickness detection plate (to). Rotating sorting tube (
The 9-layer thickness detection plate (23) is guided smoothly to the supply side and the discharge side of the 9-layer thickness detection plate (23), and is prevented from falling onto the stacked layer below from the lower end of the rotating sorting tube (11) along the rotational direction. be done. Therefore, the grains do not stay on the top surface of the first layer thickness detection plate, and the vertical movement of the layer thickness detection plate @ is performed smoothly, and the amount of grains to be sorted in the one-rotation sorting cylinder α℃ is reduced. Accurate detection is possible, and the grains that have fallen onto the layer thickness detection plate (top) are guided and dropped to both the left and right sides based on the rotation direction of the rotating sorting tube at 0°C, and the grains are guided down to the 1st layer thickness detection plate. Rotating sorting cylinder from the rear end (
11) because it is not reduced onto the flow stack at the rear in the direction of rotation.

When the grains fall from the rear end of the layer thickness detection plate (to) to the flow layer 10, the flow layer of grains to be sorted formed by one rotation of the sorting cylinder (11) moves below the layer thickness detection plate (23). Only the grains that fell backwards through the top of the five-layer thickness detection board.

There is a problem in that grains to be sorted are layered in a large number of layers, and the detection results at the layer thickness detection plate grains are not accurate.However, in this embodiment, this problem is solved and accurate layer thickness can be obtained. It is capable of detecting thickness.
