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 this type of rice polishing machine, the process from dehulling to rice polishing is carried out continuously in one machine, but the circulation type rice polishing device that performs the rice polishing work is based on a predetermined amount of brown rice. Therefore, when a predetermined amount of brown rice that has been processed from the removing device through the sorting device and supplied to the rice milling device is put into the rice milling hopper, the operation of the removing device must be stopped to stop the supply of brown rice. However, in the past, all such stop operations were detected by the operator's eyes and were carried out manually, which not only required a lot of manpower from the time the machine started operating until the brown rice was finished. However, it had many drawbacks, such as the need for skill to operate it.

This invention was proposed to solve the above-mentioned conventional drawbacks, and in the continuous process from dehulling to rice polishing, when a predetermined amount of dehulled brown rice is put into the rice milling hopper, the The amount is detected and the supply of paddy to the dehulling section is automatically stopped, thereby automating the dehulling and rice milling processes, reducing manpower, making the process more uniform, and improving efficiency. This is not intended.

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.

A removing fan 21 having a large number of blades 20 is provided, and the removing case 18 is provided with a feed hose 22 whose upper end opens above the sorting section of the sorting device C, which will be described later. A shutter 40 is provided at the inlet 36 at the lower end of the paddy hopper 17, which communicates with the removal case 18, so that it can be opened and closed, and one end of the shutter 40 is attached to an operating mechanism 41 such as a solenoid. When the detection body 16 of the rice polishing hopper 17 is activated, it slides in the direction of the arrow in FIG. 3 to open and close the inlet 36. In this embodiment, the shutter 41 is of a sliding type, but it may also be a rotary type, and the actuation mechanism 41 is not limited to a solenoid, but may also be a small motor or other suitable type. It is possible to use the following.

Further, as is clear from FIGS. 2 and 4, the sorting device C has a sorting fan 25 provided at the bottom of the sorting section 24 in which the required flow plates 23 are arranged, and a sorting fan 25 at the upper part 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 grains are discharged to the outside of the machine through a 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 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. In this case, the shutter 40 is in an open state as shown in FIG.
enters the removing case 18 from the inlet 36 at the lower end, and as the removing fan 21 rotates, it passes between the blades 20 from the center of the removing fan 21 to the outer periphery, and furthermore, it passes through the lining of the inner surface of the case 18. The husks (mixture of brown rice, grains, and paddy) are passed through the feed hose 22 to the next sorting section 2 by the wind force generated by the dehulling fan 21.
It will be sent to the top of 4.

The granules sent to the sorting section 24 are passed through the sink plate 2
3, the rice grains are sucked in by the rotation of the sorting fan 25 and discharged outside the machine through the discharge duct 28, and the rice grains are sorted and flowed down to the grate opening 29 provided on the sink plate 23. and is ejected from 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 flowing into the grain feeding chamber 4 of the rice milling device A from the brown rice supply port 15 is sent rearward inside the grain feeding tube 2 by the rotation of the milling roll 3, passes through the circulation case 5, 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 case 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 to activate the switch 16a. The solenoid 42 provided in the removing device B is activated to slide the shutter 41 that had opened the inlet 36, thereby closing the inlet 36. In this case, the rotation of the prime mover M may be simultaneously stopped by operating the switch 16a. If the inlet 36 is closed and the supply of paddy is stopped, or if the prime mover M is also stopped, neither shedding nor sorting will be performed, and therefore the supply of brown rice to the milled rice hopper 6 will be stopped.

Once brown rice has been loaded into the rice milling device A in this way, open the shutter 14 of the grain feeding chamber 4 of the rice milling device A, and at the same time push down the resistance plate 7 as shown by the chain line in Figure 1. The brown rice is circulated while applying pressure resistance inside the grain feeding cylinder 2 and the circulation case 5. In addition,
As mentioned above, the prime mover M is activated by the operation of the switch 16a.
In the case where the power supply circuit of the prime mover M is also stopped, the power supply circuit of the prime mover M is switched to a circuit (not shown) in which the detection body 16 does not work, and then the prime mover M is started to rotate again. Then, the brown rice is finished as polished rice after being circulated for a required period of time, and the rice bran generated during this milling is passed through the bran removal screen 11 located at the bottom of the grain feeding tube 2, and is transferred to the suction duct 37 by the sorting fan 25.
and passes through the duct hose 12 to the sorting fan 25.
It is sucked in and 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 polished, the milled rice outlet 9 at the end of the grain feeding tube 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.

When the rice grains are discharged, the actuating plate 16b of the detection body 16
When the front part of the paddy is lowered and the switch 16a is turned off, the solenoid 41 slides the shutter 40 in the reverse opening direction, the inlet 36 is opened, and paddy is supplied, removed and sorted, and sent to the rice milling device A. The supply of brown rice will begin, and the same actions as described above will be repeated.

In the above-mentioned embodiment, brown rice is transferred from the sorting device C to the rice milling device A by supplying the brown rice to the grain feeding chamber 4 of the rice milling device A. Of course, it is also possible to supply the brown rice from the sorting device C to the rice milling hopper 6 using a grain frying device and straining it, as is conventionally done.

As explained above, the present invention has a circulating rice milling device, a removing device, and a sorting device adjacent to each other in the machine body, and these devices are communicated with each other, so that everything from paddy to rice polishing can be done consistently within one machine body. Not only is the operation simple and highly efficient milled rice can be obtained, but the upper end of the rice milling hopper is equipped with a detection body for charging unpolished rice, and the inlet at the lower end of the rice hopper is equipped with a A shutter is provided to open and close the rice hopper, and the shutter is opened and closed by an operating mechanism that responds to the operation of the detection body.When a predetermined amount of brown rice is loaded into the rice milling device, the shutter of the paddy hopper is automatically activated. It is possible to close the rice cracker, stop the paddy supply, and stop the brown rice loading.
It will be possible to automate the removal and rice polishing process,
Not only does this reduce manpower, but it also allows uniform rice milling to be carried out with high efficiency without requiring any skill. Furthermore, since the amount of brown rice loaded is detected based on the height of brown rice loaded in the rice milling hopper, the amount of loaded brown rice can be accurately detected, and many other excellent effects are exhibited.
