Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind separator for a hull sorter.

[0002]

[Prior Art] Hulling part for hulling, sloping rice wind selecting part for wind-selecting spilled rice from the hulling part, mixed-rice selecting part for separating and selecting mixed rice into paddy and brown rice, mixed-rice frying There is a hulling and sorting machine composed of a grain machine, a brown rice fried machine, and the like. In such a hulling and sorting machine, in order to remove dusts from brown rice taken out from the brown rice grain mill, there is a grain polishing machine equipped with a suction dust remover to clean the brown rice. In the conventional device, the wind from which the dust of brown rice of the suction dust remover is removed by suction is connected to the suction dust remover of the sliding rice wind selection unit at the front of the machine body through the dust suction passage and discharged.

[0003]

In the conventional device,
The exhaust air from the suction dust remover was sent directly to the suction dust remover in the scraped rice air selection section, merged with the main sorting air and discharged outside the machine. Therefore, the present invention aims to effectively utilize the suction air generated by the suction dust remover, and supplies the suction air of the suction dust remover to the start end side of the slide rice wind selection path of the slide rice wind selection unit. In addition, it is intended to improve the sorting efficiency of the sliding rice wind sorting unit while removing dust from brown rice by using it as an auxiliary sorting wind for sorting the sliding rice in the sliding rice wind sorting unit.

[0004]

The present invention has taken the following technical means in order to solve the problems of the prior art. That is, the present invention is directed to a hulled rice portion 1, a sludge-down rice wind-separation unit for wind-separating down-soiled rice from the hulled rice portion 1, a mixed-rice sorting unit 3 for separating and sorting the mixed rice into paddy / brown rice, and mixed rice. In a hulling and sorting machine having a fried grain machine 4 and a brown rice fried machine 5, a suction dust remover 30 for removing dust of brown rice is provided at an outlet portion 5a of the brown rice fried machine 5 located at the rear of the machine body. , Suction dust remover 30
Connected to the starting end side of the sliding rice wind selecting passage 10 of the sliding rice wind selecting portion 2 in the front part of the machine body through the dust suction passage 31 and the diffusion air passage 32 that disperses the sucked air in the width direction. This is a configuration of a wind sorting device of a characteristic hull sorting machine.

[0005]

[Function] The deciduous rice hulled by the hulling section 1 is wind-selected by the fluffed-rice selecting section 2 and the mixed rice after the wind-selection is sent to the mixed-rice selecting section 3 to remove paddy / brown rice. The brown rice after separation and sorting is taken out of the brown rice fried machine 5 at the rear of the machine body. When taken out from the brown rice fried machine 5, the take-out port portion 5 of the brown rice fried machine 5
The brown rice passing through a is sorted by the suction wind of the suction dust remover 30 and dusts are removed. In addition, the suctioned wind from which dusts have been removed passes through the dust suction passage 31 and the diffusion wind passage 32 that is dispersed in the width direction, and flows into the slide-down rice wind selecting passage 10 in the slide-down rice wind selecting passage 10 in the front portion of the machine body. Inflow to the starting side. At that time, the diffused air passages 32 disperse and flow in the left-right direction of the scraped rice-air selection passage 10, so that the sorted air is substantially even in the left-right width direction.
The scraped rice from the paddy hull 1 is properly sorted, and the suction dust collector 11 is used.
Is combined with the main selection wind and discharged.

Then, the crankshaft 51 rotates, and the crankshaft 52, the swing arms 50, 50, ...
The swing selection plates 17, 17, ... Reciprocate diagonally up and down. At this time, when the swing selection plates 17, 17, ... Are moved forward to the right side which is the upper side of the swing, and then returned to the left side which is the lower side of the swing,
The weight 56 weakens the return motion to the swaying side, and vibration and noise can be reduced.

Although the weight 56 is used in this embodiment, a tension spring 57 may be connected to the other end of the wire 54 as shown in (2) of FIG. As shown in (3) of 6, a similar structure may be adopted in which the pulling or compressing springs 57, 57 are provided between the rocking upper side end and the rocking side end of the rocking machine frame 49 and the machine body 58. You can expect an effect.

Next, the operation of the embodiment shown in FIG. 1 will be described. When working with a paddy sorting machine, the rotating parts of the machine body are driven, the paddy is put into the paddy hopper 6, and the paddy is supplied to the paddy chamber 8. Then, the grains are hulled in the grain hulling chambers 8 which are rotating in the opposite directions, and the grain-falling rice is the down-pulled rice wind selection path 10 below.
Will be dropped and supplied. The scraped rice supplied to the scraped rice wind selecting passage 10 is sorted by the sorting wind, and the light rice husks flow toward the end side of the scraped rice wind separating passage 10 and pass through the suction dust collector 11 and the dust exhaust pipe 14. The porridge that has been discharged to the outside of the machine and is relatively light is porridge receiving gutter 13
The mixed rice of heavy paddy and brown rice is dropped and sorted to the slide-down rice receiving trough 12.

Next, the fallen rice which has been dropped and sorted on the fallen rice trough 12 is conveyed to one side by the fallen rice spiral, and then,
The rice is fried by the mixed rice fried machine 4, passed through the mixed rice hopper 15, the distribution / supply gutter 18, and the distribution case 19, and then the rocking sorting plates 17, 1
7, ... In this way, the swing selection plate 1
The mixed rice fed to 7, 17, ... is reciprocally oscillated vertically and horizontally by an oscillating arm (not shown), and the grain size
The brown rice, which is selected according to the magnitude of specific gravity or the difference in frictional resistance, is distributed unevenly on the upside in the lateral direction, is separated by the brown rice partition plate 20 and taken out, and passes through the brown rice gutter 22 and the brown rice flow path 23, It is fried by the brown rice fried machine 5 and taken out of the machine. Further, the mixed rice that is unevenly distributed in the lateral middle portion of the rocking sorting plates 17, 17, ...
