Description

[Detailed description of the invention] The present invention has a rubber roll type removing device and a rice polishing device adjacent to each other within the machine frame, and a wind sorting section and a hulled rice transfer device are arranged below the removing device. The upper device connects the rice milling mouth supply funnel and hulled rice transfer device above the rice milling device, and also connects the suction winch of the wind sorting section to the bran grain discharge port, from dehulling to milling in one pass through each device. This relates to a rice hulling machine that completes the following operations.

In conventional rice hulling machines, the hulled rice that has passed through the dehulling device flows downward and is separated into paddy grains and grains by wind sorting with a suction winnower, and the paddy grains are quickly discharged from the machine. was. Furthermore, the grains were supplied to the rice milling device, the bran was removed, and the polished rice was taken out from the take-out port, and the bran flowed downward and was scraped out of the machine from the discharge port. Therefore, when the rice huller and rice miller is in operation, paddy grains and bran are discharged from two places, which pollutes the area around the machine and causes dust to float around, making it difficult to clean up after work.

The present invention has been made to eliminate the above-mentioned drawbacks, and aims to provide a rice hulling machine that improves the performance of rice hulling and milling, and that is ultra-compact and can be simply and compactly installed within a single machine frame. .

The present invention will be described below based on the illustrated embodiments. FIG. 1 is a schematic longitudinal sectional view of a rice hulling machine, and FIG. 2 is a schematic cross-sectional view. In the figure, 1 is a machine frame, 2 is a paddy supply funnel, and 3 is a removing device, which is a pair of rubber rolls, supported by a roll shaft, etc. The device 3 has a wind sorting section 13 below it, and is located at approximately the center of the machine frame 1. A suction port 12 is opened and a wire mesh or the like is stretched in order to suck outside air using the suction winnower 5. Next, after wind sorting the grains and paddy grains, the grains are conveyed to one side by a hulling rice transfer device 4 consisting of a screw conveyor, and then transported to one side by a lifting device 1.
At step 4, the rice is transferred to a rice milling mouth supply funnel 6 installed in parallel with the paddy supply funnel 2. At the bottom of the funnel 6, a rice milling device 7 consisting of a rice milling roll or the like is installed to remove bran from the mixed rice consisting of brown rice and hulled rice.The device 7 has a polished rice outlet (not shown) and a bran/hull discharge port 10 at the bottom. provided. On the other hand, the rice grains sorted by the wind sorting section 13 are sucked into the suction winnower 5, communicated with the cyclone 8 having a substantially conical shape by the suction winnower tube 15, and then dropped into the bran rice grain outlet 10. Do it. in this case,
Above the cyclone 8 is provided a suction and wind exhaust port 9 that opens toward the outside of the fuselage frame 1.
A wire mesh or the like is stretched over the spacer in order to exhaust the air from the suction winch 5 to the outside of the fuselage frame 1.

Since the present invention is constructed as described above, each drive shaft,
If a pulley or the like is fitted to the driven shaft and a transmission belt is attached between each pulley, the electric motor 11 is started, unhulled rice is introduced into the paddy supply funnel 2, and the paddy supply shutter 17 is opened. The hulled rice removed by the device 3 flows down and is sorted and separated into paddy grains and grains in the wind sorting section 13, and the grains are transferred to the rice milling port supply funnel 6, and are transferred to the rice milling device 7 by opening the rice milling port supply shutter 18. The bran is removed from the polished rice using internal milling rolls, etc., and the bran is stored in the bran/paddy discharge port. On the other hand, rice grains with a light specific gravity are sucked into the suction winnower 5 by ventilation from the suction port 12, transferred to the cyclone 8 through the suction winch pipe 15, and discharged to the bran rice grain outlet.

According to the present invention, as described above, paddy grains are collected from the suction winch 5 in the machine frame 1 through the suction winch pipe 15 to the cyclone 8 and into the bran and paddy discharge port 10 at the bottom of the rice milling device 7. Because of this structure, unnecessary rice grains and bran generated during the rice hulling work are stored in one place within the machine frame 1. In addition, compared to conventional machines, it prevents dirt on the machine and its surroundings due to paddy and bran during work.
Therefore, cleaning after the work is facilitated, which is very effective in carrying out the rice-hulling and rice-polishing work. Furthermore, the rice hulling machine of the present invention has advantages such as being ultra-compact, compactly installed within a single frame, and operable with household power, making it easy to use.
