Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice removing machine in which a circulating rice milling device, a removing device, and a sorting device are provided adjacent to each other in the machine body.

In conventional rice polishing machines, when the brown rice that has been sorted through the removing device and sorting device is put into the hopper of the rice milling device, it is put into the hopper from the top of the hopper. In addition to the above, a special grain lifting device had to be installed, which not only complicated the mechanism but also made it impossible to make the aircraft compact.

The present invention was proposed in order to solve the above-mentioned conventional drawbacks, and it fundamentally changes the means for loading brown rice into a rice milling device, and transfers the sorted brown rice to the rice grains that are opened in the grain feeding chamber of the rice milling device. Supply it to the supply port of
By using the rice milling device's grain transport mechanism, rice can be milled by loading it into the hopper, eliminating the need for a grain lifting device for loading brown rice, simplifying the mechanism, and making the machine easier to use. The aim is to provide a compact and inexpensive rice removing machine.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is a box-shaped machine body, and inside this machine body 1, there is a circulating rice milling device A on one side.
However, on the other side, a removing device B and a sorting device C are installed in series in front and behind.

As shown in FIGS. 1, 3, and 4, the circulating rice mill A has a milling roll 3 disposed horizontally in a grain feeding tube 2, and a milling roll 3 disposed in the front part of the grain feeding tube 2. A grain feeding chamber 4 is formed at the rear, and a reflux chamber 5 is formed upward at the rear. Also, above the grain feeding chamber 4 and the circulation chamber 5, there is a rice milling hopper communicating with each of the chambers 4 and 5. 6 is provided. A resistance plate 7 is attached to the upper part of the grain feeding chamber 5 so that it can be opened and closed by an adjustment lever 8, and a rice polishing outlet 9 and a discharge gutter 10 are provided at the rear end of the grain feeding tube 2. At the same time, a bran removal screen 11 and a suction duct 37 provided with a duct hose 12 are provided at the lower part of the grain feeding cylinder 2.

The configuration explained so far is basically the same as the conventional circulating rice milling device, but in this invention,
Rice grain fall port 1 at the connection between grain feeding room 4 and hopper 6
3 is provided with a shutter 14 that can be opened and closed freely,
A brown rice supply port 15 is provided in the grain feeding chamber 4 at the bottom of the shutter 14, and a detection body 16 is provided inside the upper end of the hopper 6 to detect the amount of brown rice loaded into the hopper 6. is provided. This detection body 16 has a main body 16a with a switch inside.
One end of the actuating plate 16b is rotatably attached to the lower surface, and a contact point 16c is provided at the tip of the rotating part, so that the amount of brown rice to be spread can be adjusted to a predetermined height as shown by the chain line a in Fig. 1. When this happens, the actuating plate 16 is pushed up by the brown rice and comes into contact with the contact 16c, thereby stopping the drive motor of the removing device C, which will be described later, and stopping the supply of brown rice to the hopper 6.

As is clear from FIGS. 2 and 3, the removing device B includes a removing case 18 whose inner surface is lined at the lower end of the paddy hopper 17.
Inside 8 is a drive shaft 19 that is coaxial with a sorting fan that will be described later.
A removing fan 21 having a large number of blades 20 is rotated by the removing fan 21, and the removing case 18 is provided with a feed hose 22 whose upper end opens at the upper part of the sorting section of the sorting device C, which will be described later. .

As is clear from FIGS. 2 and 4, the sorting device C is equipped with a sorting fan 25 at the bottom of the sorting section 24 in which the required sink plates 23 are arranged, and a sorting fan 25 at the top of the sorting section 24. The upper end of the feed hose 22 of the above-mentioned removing device B is opened 26, and the sorting fan 25 is rotated by a drive shaft 19 common to the above-mentioned removing fan 21. From the suction port 27 along the direction, the sorting section 24
Suctioning the rice hulls flowing down on the inner sink plate 23,
The rice husks are discharged outside the machine through a chaff discharge duct 28 provided in the cutting line direction of the sorting fan 25. The suction port 27 is further connected to the end of the duct hose 12 of the rice milling apparatus A described above. In addition, the sink plate 23 at the lowest stage of the sorting section 24 is provided with a grate 29, and a brown rice discharge gutter 3 is provided.
0 is provided, and its tip is connected to the rice polishing device A described above.
The brown rice supply port 15 is connected to the brown rice supply port 15.

Next, the operation of the rice removing machine of the present invention having the above-mentioned configuration will be explained. They are each rotated by a prime mover M installed inside.
That is, the prime mover M is provided with pulleys 32 and 33, and one pulley 32 is connected to the drive shaft 3 of the polishing roll 3.
The other pulley 33 is associated with a pulley 35 provided on the drive shaft 19 of the removing fan 21 and sorting fan 25.

First, paddy is loaded into the paddy hopper 17 of the removing device B. The paddy enters the removing case 18 by opening a shutter (not shown) provided at the inlet 36 at the lower end of the hopper 17, and by the rotation of the removing fan 21, the blades are sent from the center of the removing fan 21 to the outer periphery. The grains are removed by passing through the fan 20 and then violently rubbing against the inner lining of the case 18, and the resulting grains (a mixture of brown rice, rice grains, and rice husks) are removed from the fan 2.
By the wind force generated in step 1, the particles are sent through the feed hose 22 to the upper part of the next sorting section 24.

The grains sent to the sorting section 24 are passed through the sink plate 2.
3, the rice husks are sucked by the rotation of the sorting fan 25 and discharged outside the machine through the discharge duct 28, and the rice husks are sorted and flowed down to the grate opening 29 provided on the sink plate 23. It is ejected outside the aircraft. The brown rice then flows down to the brown rice discharge gutter 30 and flows into the brown rice supply port 15 of the rice milling device A.

The brown rice that has flowed into the grain feeding chamber 4 of the rice milling device A from the brown rice supply port 15 is sent backward through the grain feeding tube 2 by the rotation of the milling rolls 3, passes through the circulation chamber 5, and enters the hopper 6. It will be stored in the hopper 6.

In this case, the shutter 14 of the grain feeding chamber 4 is closed to prevent the brown rice that has entered the hopper 6 from being supplied to the milling rolls, and the adjustment lever 8 is turned upward so that the resistance plate 7 faces upward. Make sure there is no pressure inside. When the brown rice is successively pushed up into the hopper 6 from the circulation chamber 5 and reaches a predetermined amount, the actuation plate 16b of the detection body 16 provided at the upper end of the hopper 6 comes into contact with the contact point, and the switch 16a is activated, causing the prime mover M to be activated. Stop rotation.
As a result, the stripping device also stops, and stripping and sorting are no longer performed. Next, the inlet 3 of the removing device B
6 is closed, the power supply circuit of the prime mover M is switched to a circuit (not shown) in which the detector 16 does not work, and the prime mover is rotated again, and the shutter 14 of the grain feeding chamber 4 is closed. At the same time, the resistance plate 7 is pushed down as shown by the chain line in FIG. 1, and the brown rice is circulated while applying pressure resistance inside the grain feeding cylinder 2 and the circulation chamber 5. The brown rice is milled while experiencing this pressure resistance, and after being circulated for the required time, it is finished as polished rice. In addition, the rice bran generated during this rice milling passes through the rice bran removal screen 11 on the lower side of the grain feeding cylinder 2, enters the suction duct 37 by the sorting fan 25, and is sucked into the sorting fan 25 via the duct hose 12. It is discharged outside the machine through the discharge duct 28.

At this time, since the milled rice in the grain feeding tube 2 is suctioned to remove bran by the sorting fan 25, the suction air passing between the rice grains has the effect of cooling the rice grains.
It is possible to perform low-temperature whitening without heating the rice grains.

Once the rice grains have been milled, the milled rice outlet 9 at the end of the grain feeding cylinder 2 is opened while the milling roll 3 is rotated, and the rice grains are taken out of the machine from the discharge gutter 10.

As explained above, in the present invention, the circulating rice milling device, the removing device, and the sorting device are installed adjacent to each other in the machine body, and these devices are communicated with each other, so that everything from paddy to rice milling can be done consistently in one machine body. In addition to being easy to operate and highly efficient in milling, the brown rice sorted by the sorting device is directly supplied from the sorting device to the grain feeding chamber of the rice milling device, where it is sent to the milling rolls. Since the grain action is used to force the brown rice into the hopper, the grain lifting device, which was indispensable to force the brown rice into the hopper of conventional circulating rice milling equipment, can be removed, and the mechanism can be simplified. It is possible to significantly simplify the machine, and also to make the machine body compact, and in particular, the height of the machine body can be significantly reduced, thereby making it possible to manufacture the rice removing machine at low cost.

In addition, rice bran can be sucked and discharged using the suction air of a sorting fan for sorting out grains, so there is no need to provide a separate fan for discharging rice bran as in the past. The mechanism can be further simplified, and low-temperature whitening can be performed by suction and bran removal. In addition, a detector for detecting unloaded brown rice is installed at the upper end of the hopper of the rice milling device, so that when the amount of brown rice reaches a specified amount, the removing device can be automatically stopped and the supply of brown rice to the hopper can be stopped. Therefore, it is possible to automate driving and simplify operation. Moreover, since the amount of brown rice loaded is detected by the height of brown rice in the hopper, the amount of loaded brown rice can be detected and the switch can be operated correctly and reliably, resulting in many excellent effects. It is something that can be demonstrated.
