Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a grain removal device of a rice swamp sorting device, and in the rice tank sorting device, a wind sorting device is installed in the brown rice removal process of the oscillating sorting section, and the oscillating sorting process is improved. By flowing the brown rice mixed with impurities such as flour/rice husks through the wind sorting device, it is a high-performance machine that reliably, smoothly, and quickly mass-produces high-quality selected brown rice that is free from impurities. The aim is to develop and provide a new device.

To explain the present invention with reference to embodiment figures, the reference numeral 1 in the figures is:
It is a box-shaped machine frame with a built-in wind sorting section 2 for wind-selecting the deflocated materials of paddy, brown rice, and rice husks. They are arranged in parallel with the dynamic sorting section 4 to integrally form a hulling sorting device main body, and the machine frame of the wind sorting section 2 of the device main body or the oscillating sorting section 4 connected thereto is provided with a grain removal device to be described later. A grain removal device equipped with a hopper is provided.

The wind sorting section 2 includes a flow passage 5, a wind speed chamber 6, and an air flow chamber 6 for sorting the defloated materials of paddy, brown rice, and rice husks inside the machine frame 1.
A wind fan 7 is arranged and installed integrally.

The hulling section 3 is provided with a supply hopper 9 at its upper part, and a pair of rolls 8, 8 for hulling are rotatably mounted inside.・Paddy・
It is integrally formed by mounting a sorting board 10 for swinging and sorting the mixed grains, and providing a machine frame 11 in which the swinging mechanism is housed in the lower part. 12 is a paddy outlet provided on the discharge side of the sorting board 10, 13 is a paddy/brown rice mixed grain outlet, and 14 is a brown rice outlet. Next, regarding the grain removal hopper 15, as shown in FIG. A grain chamber 19 provided with an air intake port 33 on the body, and an artificial air chamber 21 provided with a BE air port 20 on the surrounding wall body are integrally formed by communicating through a Liu wall 23 with a ventilation window 22, In FIGS. 1 and 2, the machine frame 1 of the wind sorting section 2
The machine frame 11 of the swinging sorting section 4 is mounted on and formed integrally,
The grain removal hopper 15 is attached to the side wall of the ventilation chamber 24 provided inside the swing sorting machine frame 11, and the grain removal port 14 of the sorting machine is connected to the flow grain chamber input row 6. A grain frying thrower 26 is attached to a room threshing row 7 and integrally formed.

Reference numeral 27 denotes a ventilation opening provided in the upper wall of the machine frame 1, and is formed so that the air from the upper ventilation chamber 24 flows into the lower exhaust fan 7 through the opening 27. Then, the impeller 29 is pivoted to the rotary shaft extension 28 of the blower 7 in the machine frame 1, and the blower 3 is formed to form a blower device. It is connected to the surface of the inclined plate 18 of the porous wall of the shell chamber 19, and is formed so that air is blown upward from the bottom surface of the plate surface. 32 is the sorting board 1 for the mixed grains of paddy and brown rice at the bottom of the wind sorting section 2.
This is a storage tank for supplying water.

25 is a dust collector consisting of a cyclone, which is conveyed to the air outlet 20 of 9E.

In the above configuration, when raw material paddy is put into the supply hopper 9 of the hulling section 3 and the device is driven, the paddy flows down into the hulling section 3 and is hulled between the hulling rolls 8, 8. The threshed grains flow into the wind sorting chamber 6 through the flow path 5 and are wind sorted, and the mixed grains of paddy and brown rice are accumulated at the bottom of the chamber 6 and fried in the storage tank 32, where they are shaken sorted. One sorting board in section 4 is supplied.

Then, each grain is sorted and separated by the shaking action of the sorting board surface and flows to the discharge side of the board surface, the paddy flows out from the paddy outlet 12 and is returned to the paddy tank supply hopper 9, and the mixed grains are mixed grains. The brown rice flows out from the take-out port 13 and is returned to the bottom of the winnowing chamber 6, and the brown rice flows out from the brown rice take-out port 14 and flows down to the input port 16 of the hopper 15. In this hopper 15 for taking out hardwood,
Wind generated by the rotation of the impeller 29 of the blower 30 provided on the side wall of the lower machine frame 1 reaches the porous inclined wall plate 18 through the air passage 31, and is blown upward from the lower surface of the porous wall surface of the plate 18. This exhaust air (dust-containing wind) flows into the hopper Kazuhiko E wind chamber 21.
The dust is collected by the cyclone 25 from the air outlet 20 of 9E and released into the atmosphere. Therefore, the brown rice flowing down from the input port 16 onto the inclined porous wall plate 18 of the flowing grain room is air-sorted by wind on the porous wall surface to remove impurities such as grains and rice husks mixed in during the oscillating sorting action. The perishable matter is separated and flows into the ventilation chamber 21, and the wind-selected brown rice flows down to the lower part 8E grain □17 and is discharged and stored in a container etc. outside the machine by the thrower 26, and the container is stored as appropriate. It will be transported to the next stage and sent to the next stage. In the above embodiments, a cyclone was used as the ant collecting device, but any dust collecting device such as a back filter can be used instead of the cyclone. FIG. 4 shows another embodiment of the present invention, in which the air intake port 34 of the air blower 30 is connected to the air exhaust port 201 of the material removal hobber 15, and the air passage 31 of the air blower 30 is connected to a cyclone back filter, etc. The air intake port 33 of the grain removal hopper 15 is open to the atmosphere. In this embodiment, the air passage 31 of the air blower 30 is integrated with the rice husk duct 34 provided on the artificial wind side of the rat ejector 7 shown in FIG. Good too.

In short, the grain removal device of the rice hulling and sorting device of the present invention is a paddy tank sorting device in which a hulling section and a swinging sorting section are arranged side by side on the upper part of the machine frame. A grain removal hopper, which forms a grain chamber and has a 9E air outlet and a suction port on its wall, is attached to the main body of the huller sorting device, and the input port of the hopper flow grain chamber is connected to the oscillating sorting section. The hopper grain chamber is connected to the brown rice take-out port of the sorting machine, and the hopper grain chamber is connected to a blower device, and directional air is ejected into the grain chamber to remove dust and chaff from the brown rice. The jet is sent to the air outlet side to separate the impurities, and the separated impurities are removed outside the machine by strong wind, so it is possible to remove the impurities from the brown rice, which was considered difficult. By simply attaching it to the main body of the device, the structure is simplified, the manufacturing cost is reduced, and it is always effective in mass-producing selected brown rice without contamination with impurities, reliably, smoothly, and quickly.
