Abstract

PURPOSE:To always exhibit the best performance in a rice husker and a rice milling machine by passing exhaust through a rocking sorting devise from the blower of a rubble takeout machine and sucking this exhaust through a sorting air path of the rice husker from an exhaust path by a blower for rice husking and discharging the exhaust to the outside. CONSTITUTION:A rice husker 6 is provided to the upper part of the inside of a mechanical body 1. The grains of paddy are husked between the husking rolls 2, 2. Sorting wind is sucked by a blower 3 for rice husking and passed through a sorting wind path 4. While the husked grains of paddy are allowed to fall on a sorting shelf 5, these are sorted into unpolished rice and chaff. A rocking sorting device 7 which receives supply of unpolished rice is provided to the downside of the rice husker 6. Air blasting is performed to the rocking sorting machine 7 from a blower 8. While unpolished rice is floated, a rubble takeout machine 9 rocks and sorts both unpolished rice and rubbles admixed therewith by rocking and sorting. Sorting wind is pass ed through the rocking sorting device 7 and exhausted to an exhaust path 10. The terminal side of this exhaust path 10 is faced and provided to the starting end side of the sorting wind path 4. As a result, the rice husker 6 and a rice milling machine always exhibit excellent performance.

Description

[Detailed description of the invention] Industrial applications TECHNICAL FIELD The present invention relates to a stone dust extractor for a grain conditioning processing device.

Conventional technology Conventionally, when paddy grains are fed into a rice grain inlet, the grains are supplied to the dehulling roll of the hulling machine, and are dehulled between the I and the hulling machine. The sorting air sucked in by the machine passes through the sorting air passage, and the hulled rice grains are sorted into brown rice and rice husks while flowing down on the sorting shelf, and the rice husks are discharged outside the machine. It is supplied to the rocking sorting device of the stone dust removal machine installed at the bottom of the hulling machine, and the air from the blower passes through this rocking sorting device, causing the brown rice to float and being sorted into brown rice by shaking sorting. This is a stone waste removal machine of a grain conditioning and processing device in which the stone chips mixed in the grain are separated by the rocking sorting device, and the exhaust air from this blower to the rocking sorting device is By circulating the dust inside the machine, the dust mixed in the exhaust air was circulated and naturally settled to the lower part of the machine.

Problems to be Solved by the Invention When working with a grain conditioning and processing device, when paddy grains are fed into one paddy grain feeder, the paddy grains are fed to the shredding rolls of the hulling machine and passed between the shredding rolls. The husked rice grains are husked by the husks, and the sorting air sucked in by the huller exhauster passes through the sorting air duct, and the husked rice grains are air-sorted into brown rice and rice husks while flowing on the sorting shelf. The rice husks are discharged outside the machine, and the brown rice is supplied to the rocking sorting device of the stone dust removal machine located at the bottom of the huller, and the air from the blower passes through the rocking sorting device.
While the brown rice is floated and shaken, the brown rice and the stone chips mixed in the brown rice are sorted by the shaking sorting device.
The sorted stone chips are discharged outside the machine, and the sorted brown rice is supplied to a rice milling machine and polished.

During this stone debris removal work, the exhaust air that has passed from the blower to the rocking sorter is circulated within the stone debris remover, and the dust generated by the stone debris remover is circulated and naturally removed. By settling to the lower part of the body, this dust may adhere to these integrated hulling machines, rice milling machines, etc., and the performance of these machines deteriorates due to this dust adhesion. This has happened, but this is what we are trying to prevent.

Means for Solving the Problems The present invention has rolls 2, 2 for removing rice grains in the upper part of the machine body 1.
The huller removes and picks the rice grains between the rice crackers and sucks them in with the huller exhauster 3, which is then passed through the sorting air passage 4 to sort the hulled rice grains flowing down the sorting shelf 5 into brown rice and rice husks. At the same time, a swing sorting device 7 is installed below the huller 6 to receive the brown rice.
A stone waste removal machine is provided, which blows air from a blower 8 to the swing sorting device 7 to float the brown rice, and performs swing sorting to separate the brown rice from the stone chips mixed in the brown rice. In the grain conditioning and processing apparatus equipped with a grain conditioning and processing device 9, the terminal end side of the air exhaust passage 10 through which the swinging sorting device 7 passes through and exhausts the air is directed toward the starting end side of the sorting air passage 4. The structure of the stone dust removal machine is characterized by:

Effect of the invention When the rice grains are fed into the rice grain supply port, the rice grains are supplied to the hulling rolls 2, 2 of the hulling machine 6, are hulled between the hulling rolls 1, 1, and are sent to the hulling waste. When the sorting air sucked by the wind fan 3 passes through the sorting air passage 4, the hulled paddy grains are transferred to the sorting shelf 5.
While flowing down, this sorting wind separates the rice into brown rice and rice husks, and the rice husks are discharged to the outside of the machine 1, and the brown rice is supplied to the rocking sorting device 7 of the stone waste extractor 9 located below the huller 6. When the air from the blower 8 passes through the oscillating sorting device 7,
While floating the brown rice, it is shaken and sorted into brown rice and stone chips mixed in this brown rice, and the sorted stone chips are discharged outside the machine 1, and this sorted brown rice is supplied to the rice milling machine. It is polished and refined.

During this stone dust removal work, the exhaust air that has passed through the rocking sorting device 7 from the blower 8 passes through the air exhaust path 10 of the stone dust removal machine 9 and the sorting air path 4 of the huller 6. By being suctioned and exhausted by the hulling fan 3, the dust generated by the stone dust remover 9 is sucked by the hulling fan 3 and discharged to the outside of the machine body 1.

Effects of the Invention According to the present invention, the exhaust air that has passed through the swinging sorting device 7 from the blower 8 of the stone dust extractor 9 is discharged from the exhaust passage 10 through the sorting air passage 4 of the huller 6 to the huller exhauster 3. As the air is sucked in and exhausted to the outside of the machine, the dust generated in the stone dust extractor 9 is discharged together with this exhaust air, so that this dust does not adhere to the huller 4, rice polishing machine, etc. Therefore, these rice huller 4, rice milling machine, etc. can always exhibit the best performance.
