Description

[Detailed description of the invention] This invention consists of a dehulling device and a rice milling device installed side by side within an integrated body frame, and is composed of a wind sorting section, a hulling rice transfer device, a suction winch, a cyclone, a motor, etc. This invention relates to a rice husk/bran storage box for a rice huller and rice miller that completes the hulling and milling operations of unhulled rice from dehulling to milling in one pass through the device.

The rice hulling machine of the present invention is small and compactly installed within a single machine frame, and the rice husk, bran, etc. are removed from the machine in order to prevent waste such as rice husks and bran from scattering or floating around the machine during hulling and rice milling work. It is possible to store them in the same place within the frame. In addition, the rice husk drop opening at the lower end of the cyclone that communicates with the suction karang is provided facing the rice husk/bran storage box, but the rice husks that fall due to the cyclone are not completely separated from the air blown from the suction karan, and are placed inside the storage box. Because the rice bran is blown into the storage box, the cumulative appearance of the rice bran in the storage box is poor, and the rice bran scatters and floats inside the storage box, preventing the rice from being discharged from the rice milling equipment.

This invention was developed to eliminate the above-mentioned drawbacks, and it is an ultra-compact system that collects unnecessary rice husks and bran discharged from the rice hulling process in the same place within the frame of the machine without interfering with their discharge. The aim is to provide a concise and better product.

The present invention will be explained below based on the illustrated embodiments. Fig. 1 is a schematic longitudinal sectional front view of a rice hulling machine;
The figure is a schematic longitudinal sectional plan view, and FIGS. 3 and 4 are schematic explanatory views of main parts, and the arrows in the figures indicate the direction of air blowing. In the figure, 1 is the machine frame, 2 is the paddy supply funnel, and 3 is the removing device, where a pair of rubber rolls 17 and 17' are connected to the roll shaft 23 and
23', and a wind sorting section 1 is installed below the device 3.
1 and communicates with a suction winnower 5 located approximately in the center of the fuselage frame 1, and a wire mesh or the like is stretched over the suction port 12 which is opened to suck in outside air. Further, a polished rice transfer device 4 consisting of a screw conveyor is mounted below the wind sorting section 11 in approximately parallel to the roll shafts 23 and 23', and is connected to a lifting device 16 to transfer polished rice arranged in parallel to the paddy supply funnel 2. to be transferred to the mouth supply funnel 6. A rice milling device 7 consisting of a milling roll or the like is installed at the bottom of the funnel 6 to remove the bran from the mixed rice consisting of brown rice and paddy. A rice husk/bran storage box 10 is provided. The suction chimney 5 passes through a rice husk discharge path 15 to a cyclone 8 consisting of a cylindrical part 24, an inner cylindrical part 26, and a rice husks falling port 21.
connected to. The lower part of the cyclone 8 is communicated with a rice husk/bran storage box 10, and the upper part is communicated with an exhaust port 9 opened toward the outside of the body frame 1 through an inner cylindrical part 26. A wire mesh or the like is stretched over the exhaust port 9 so that the air separated by the cyclone 8 can be discharged to the outside of the fuselage frame 1.

Therefore, in the rice husk/bran storage box 10, a partition plate 20 made of an iron plate or the like is provided with the lower part of the partition plate 20 open at a position corresponding to the discharge ratio of rice husks and bran and blocking the air blowing from the cyclone 8. It will be done.

The present invention has been made as described above, and if a pulley or the like is fitted to each drive shaft and driven shaft and a transmission belt is engaged between each pulley, the motor 19 can be started.
When the unhulled rice is put into the paddy supply funnel 2 and the paddy supply shutter is opened, the hulled rice removed by the dehulling device 3 flows down and is sorted into chaff, rice grains, etc., and brown rice and paddy in the wind sorting section 13. The separated brown rice and paddy are transferred to the rice milling port supply funnel 6, and when the rice milling port supply shutter 18 is opened, the rice milling rolls in the rice milling device 7 remove the bran into polished rice, and the bran etc. are stored in the rice husk and bran storage box 10. Ru. On the other hand, after wind sorting, rice husks, rice bran, etc. with light specific gravity are sucked into a suction winnower 5, transferred to a cyclone 8 through a rice husk discharge passage 15, and discharged into a rice husk/bran storage box 10.

Here, in the cyclone 8, the rice husks settle and fall along the cylindrical part 24 and the conical part 25 due to the wind speed from the suction chimney 5 and the centrifugal force generated by the curvature of the cylindrical part 24, and the rice husks and bran fall from the rice husks drop opening 21. The air is stored in the storage box 10, and is discharged from the inner cylindrical portion 26 while swirling. In this case, as in the embodiment shown in FIG.
The air blown into the cyclone 8 is transferred to the inner cylindrical part 2.
A part of the rice husks is discharged from the rice husk drop port 21 to the rice husk/bran storage box 10 along with the rice husks. For this reason, the rice husks that settle and fall scatter within the storage box 10, disturb the cumulative appearance, and spread to the lower part of the rice bran discharge port 27 at the bottom of the rice milling device 7, impeding the discharge of rice bran during rice milling.

Next, in FIG. 4, the exhaust air blown from the cyclone 8 is blocked by the partition plate 20 in the rice husk/bran storage box 10, and the diffusion of the rice husks to the lower side of the rice bran drop opening is suppressed. It will be done. Furthermore, by leaving the lower part of the partition plate 20 open without partitioning, rice husks and bran can be collected in a small space.

As described above, according to the present invention, by installing the partition plate 20 in the rice husk/bran storage box 10, the scattering of rice husks due to the exhaust air from the cyclone 8 is suppressed, and the diffusion of rice husks in the storage box 10 is eliminated. , the cumulative disorder of posture is also eliminated. Therefore, it becomes easy to discharge the bran from the bran dropping port. Furthermore, by opening the lower part of the partition plate 20 without partitioning it, rice husks and bran can be easily stored in a small space. Therefore, it is possible to install a storage box using a small space within the frame of the machine, and it is possible to sufficiently deal with the waste generated in normal rice hulling and rice milling operations.

As described above, the present invention has various effects.
