Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a circulating rice milling machine equipped with a removing device, a rice husk sorting device, and a circulating rice milling device.

[Conventional technology]

BACKGROUND ART Conventionally, a so-called rice removing machine has been known in which a removing device, a sorting device, and a rice polishing device are built into the same body, and the removing device and the rice polishing device are driven separately.

In addition, when supplying the brown rice sorted through the dehulling device and sorting device to the hopper of the rice milling device, the rice milling machine main body and the rice milling hopper are communicated via a grain feeding room and a circulation room, and this grain feeding room There is known a rice milling machine in which a shutter that can be opened and closed is provided at the rice grain dropping port at the connection between the rice grains and the hopper, and a brown rice supply port from the threshing device is exposed to the grain feeding chamber at the bottom of the shutter.

[Problems with conventional technology]

First, conventional rice mills of this type rely on power switching to switch the drive from the de-sorting device to the rice milling device, and are therefore equipped with a complicated power transmission device. In addition, a grain lifting device was required to transfer the deselected brown rice to the brown rice tank of the rice milling device.

Therefore, the conventional rice polishing machine requires a large amount of power, has a large and complicated built-in device, and therefore has the disadvantage that the machine as a whole becomes large and expensive.

Next, the system in which the brown rice supply port faces the grain feeding chamber of the rice milling hopper absolutely requires the above-mentioned shutter, and the operation of opening and closing the shutter is prone to erroneous operation, making it difficult to operate this type of rice milling equipment. I thought it was something.

That is, for example, if the shutter is open when feeding sorted brown rice to a rice milling device, the brown rice in the hopper may be fed to the rice milling rolls, or the grain feeding chamber may become clogged with brown rice from the hopper and the supply may stop. Otherwise, the brown rice in the hopper flows back toward the brown rice supply port on the sorting side, which not only stops the supply but also causes problems in the operation of the sorting device.

[Purpose of the invention]

The present invention improves on this by communicating the de-sorting device with the circulation-type rice milling device, so that the circulation-type rice milling device can be skillfully used for transporting and storing the de-sorted brown rice, and can also be easily used for the original rice milling work. The structure is configured so that it can be switched over, making the machine more compact and energy-saving.Furthermore, it does not necessarily require the conventional shutter mentioned above, and even if there is a malfunction in opening and closing due to the conventional shutter. An object of the present invention is to provide a circulation-type rice removal machine in which priority is given to supplying sorted brown rice to a rice milling device, and the sorting device does not have any trouble.

[Structure of the invention]

The present invention allows the outlet of a dehulling device equipped with a paddy tank at the top to communicate with a sorting device, and a circulating rice milling device equipped with a brown rice tank is provided below the dehulling device, and the rice milling machine main body of this circulating rice milling device and The brown rice tank is connected to the tip of the rice milling machine body through the circulation supply port, and the rice milling machine body, the rice milling rolls therein, and the rice milling roll chamber are installed on the rear side of the circulation supply port, and the rice sorting machine is connected to the brown rice tank through the circulation supply port. The gist is that the brown rice outlet of the device, that is, the brown rice supply port, faces the rice milling roll chamber of the rice milling machine body on the rear side from the circulation supply port, so that the de-sorting operation and the rice milling operation can be performed separately.

A wind direction plate 27 is provided at this branch point 25 and is configured to be activated by the switching operation of the wind direction handle 26, so that the communication path can be switched to the side of the rice husk air path 20 or the side of the bran removal hose 24.

Since the wind direction handle 26 is connected to the paddy shutter operating rod 4 through the wind direction switching operating rod 28, it is interlocked with the operation of the paddy shutter 3 of the removal device A.

A main body 29 of the circulating rice milling device C is provided below the sorting device B, and the main body 29, the rice milling rolls 30, and the rice milling roll chamber 31 inside thereof are both longer than conventional ones.

The exit (brown rice rear supply port) 23 of the brown rice discharge funnel 22 of the sorting device B is connected to the rice milling roll 30.
This long rice milling machine body 29 is shown facing the rear side of the machine.

The feature of the present invention is that the brown rice rear supply port 23 is provided.

The rice milling roll 30 is attached to a rice milling machine shaft 32 that is mounted on a rice milling machine main body 29, and a milled rice discharge plate 33 is provided at the end of the pushing-up side of the rice milling roll, and a rice box 34 is provided directly below it.

Further, a bran removal outlet is formed at the front lower part of the rice polishing machine main body 29, and a wire mesh 38 for removing the bran is stretched over the rice polishing machine main body 29. Numeral 39 is a bran chute provided below the bran removal outlet, one end of the bran removal hose 24 is connected to the lower end of this bran chute 39, and the other end is connected to the branch point 25 of the ventilation case 19 as described above. has been done.

40 is a resistor, and a resistance handle 4 is attached to the connection part between the reflux box 37 and the upper plate 41 of the brown rice tank 35.
2 and a resistance linking rod 43. The resistance handle 42 can be operated outside the machine, and thereby the resistor 40 and the resistance link 43 can be operated.

Further, since the resistance linking rod 43 and the paddy shutter operating rod 4 are configured to be interlocked, the resistor 4 of the rice milling device C can be operated by operating the resistance handle 42.
0, the paddy shutter 3 of the removing device A, and the wind direction plate 27 for switching the wind direction to the sorting device B or the bran removal device of the circulating rice milling device C can be operated simultaneously.

In this embodiment, by operating the resistance handle 42 upward, the resistor 40 is operated to the "weak" or de-sorting side, and the other end of the resistance link 43 is moved against the paddy shutter return spring 5 to release the paddy. acts on the lower end of the paddy shutter operating lever 4 to open the paddy shutter lever 3;
Further, the wind direction switching operation rod 28 and the wind direction handle 26 are operated in conjunction with the rice shutter operation rod 4 to operate the wind direction plate 27 so as to close the other end of the bran removal hose 24.

Conversely, if the resistance handle 42 is operated downward,
The resistor 40 operates the resistance in the circulation box 37 to "strong", that is, to the rice milling work side. At this time, the resistance link 43
Since the pressure on the paddy shutter operating rod 4 is released, the paddy shutter 3 is closed by the action of the return spring 5. In addition, the action of the return spring 5 acts on the wind direction handle 26 via the rice shutter operating rod 4 and the wind direction switching operating rod 28 to open the other end of the bran removal hose 24 and close the communication port between the ventilation case 19 and the rice husk air passage 20. The wind direction plate 27 is configured to operate as shown in FIG.

On the other hand, a rice polishing machine pulley 44 is fixed to the end of the rearward projecting portion of the rice milling machine shaft 32, and is configured to be driven together with the demachining pulley 9 by a motor 45 attached to the bottom wall inside the machine.

[Effect]

Next, the operation of the rice milling machine according to the embodiment of the present invention constructed as described above will be explained.

When the motor 45 starts operating, the demaceration pulley 9 and the rice milling pulley 44 rotate.

Next, if the resistance handle 42 is operated toward the solid line side shown in the figure, the resistor 4
0 is set to "weak" and no elaboration is performed.

In addition, the tip of the resistance linking rod 43 acts on the paddy shutter operating rod 4 to open the paddy shutter 3 of the removing device A, and the wind direction plate 2 interlocks with the paddy shutter operating rod 4.
7 communicates the rice husk air passage 20 with the ventilation case 19 and closes the other end of the bran removal hose 24.

In the removing device A, the removing shaft 8 rotates,
Accordingly, the de-machine screw 12, rotary disk 13, and suction blade 11 rotate, and air is blown in the de-machine 6 and suction case 15.

The wind inside the breakout 6 flows through the outlet 14 of the cover 10.
It is blown into the sorting device B. This blown wind passes through the air path between each swash plate 21 and passes through the suction case 1.
The rice husk enters the suction case 15 through the ventilation case 19 from the rice husk air path 20 due to the suction action caused by the wind raising in step 5, and is then blown upward through the air path 17 and the cyclone 18.

Therefore, the paddy in the paddy tank 2 enters the demasher main body one by one, is sent into the demasher 6 by the screw 12, and is violently collided with the demass rubber 7 due to the centrifugal action of the rotary disk 13 and is removed.

The mixture of brown rice, rice husks, straw waste, etc. that has been deprocessed passes through each air path while hitting the swash plate 21 in the sorting device B by the wind force of the rotary disk 13. During this time, light rice husks, straw waste, etc. are separated from brown rice and blown up.

The completely sorted brown rice flows down the funnel 22, enters the rice milling roll chamber 31 of the circulation type rice milling device C from the outlet 23, is sent forward by the rice milling roll 30, and enters the reflux box 37 from the tip of the rice milling roll 30. Being pushed up.

Since the resistance of the resistor 40 is not applied in the reflux box 37, the rice is pushed up as it is and placed in the brown rice tank 35.

On the other hand, the circulation supply port 36 of the rice milling machine main body 29 is blocked by the unsorted brown rice fed from behind the rolls, so the brown rice in the brown rice tank 35 will not flow into the roll chamber 31 from the circulation supply port 36. do not have.

That is, in this case, the circulating rice milling device C is skillfully utilized for the transfer and storage of the desorting operation.

On the other hand, rice husks, straw waste, etc. that have reached the rice husk air path 20 are
The sorting air is sent from the ventilation case 19 to the cyclone 18 through the suction case 15 and the air passage 17, and is blown upward from the cyclone 18, while rice husks, straw waste, etc. are discharged by falling from the lower mouth of the cyclone 18.

When the de-sorting is finished in this way and no brown rice is fed from the rear of the roll, the brown rice tank 3
The brown rice in 5 automatically flows into the roll chamber 31.

At this time, when the resistance handle 42 is set to the "rice milling side" shown by the chain line in the figure, the resistor 40 is set to "strong".
The rice mill is operated only for rice milling work.

That is, the brown rice in the brown rice tank 35 sequentially falls into the rice milling machine main body 29 from the circulation supply port 36, is pushed forward by the rotation of the rice milling rolls 30, and is forced into the circulation box 37 while facing strong resistance. be pumped.

At this point, the rice milling device C performs its original operation, and the brown rice is milled and returned to the tank 35, and this operation is repeated to circulate within the rice milling device C.

In addition, in the rice milling machine of the present invention, since the brown rice supply port 23 after removing the rice is provided on the rear side of the circulation supply port 36 of the brown rice tank 35, the brown rice after removing the rice can be supplied to the rice milling device C very smoothly. It is done.

That is, first, brown rice is stored in the brown rice tank 35 through the circulation box 37, and then the brown rice is stored and stored.
The transfer reaches the circulation supply port 36 of the rice milling machine main body 29, but after reaching this point, the rice milling machine of the present invention uses a system in which brown rice is supplied from the rear of the rice milling rolls 30, so the flow of brown rice is prioritized on the de-sorting side. At the same time, the supply of rice to the rice milling device C side is stopped or the flow is stopped at a reasonable level, so that overload of power can be prevented when brown rice is stored in the brown rice tank 35. In addition, brown rice does not stagnate in the de-sorting device, and good de-sorting can be continued at all times.

On the other hand, rice bran leaks from the wire mesh 38 and is discharged into the rice bran chute 39. In this case, the resistance linking rod 43 is separated from the paddy shutter operating rod 4 by the above-mentioned switching device, and the paddy shutter 3 is closed by the action of the return spring 5. Although the de-sorting operation is thereby interrupted, the rotation of the de-separating shaft 8 is not interrupted. Further, the wind direction plate 27 closes the rice husk air passage 20 and opens the bran removal hose 24 side by the action of the return spring 5.

Therefore, the suction action of the suction blade 11 acts on the rice bran removal hose 24 side, and the rice bran discharged into the rice bran chute 39 is discharged to the cyclone 18 outside the machine via the rice bran removal hose 24 and the ventilation case 19. Ru.

The polished rice that has been polished is taken out from the discharge plate 33 and stored in the rice box 34.

This rice milling work is not necessarily limited to when the paddy tank 2 is empty, but even during the de-sorting work, by switching the resistance handle 42 to the "rice milling side", only the rice milling work described above can be carried out. can.

〔Effect of the invention〕

As explained above, the rice polishing machine according to the embodiment of the present invention has the following features:
Since the brown rice supply port after removal is provided at the rear side of the circulation supply port of the brown rice tank of the rice milling device, the brown rice after removal can be supplied to the rice milling device very smoothly.

That is, first, brown rice is sequentially stored in the brown rice tank through a circulation box, and then the brown rice is stored and transferred to the above-mentioned circulation supply port of the rice milling machine body.After this arrival, the rice milling machine of the present invention Since brown rice is supplied from the rear of the rice milling roll, priority is given to the unsorting side of the brown rice flow, and the supply of rice to the rice milling equipment side either stops or stops flowing to a reasonable level, and therefore flows into the brown rice tank. It has the effect of preventing power overload when storing brown rice, and prevents brown rice from stagnating in the de-sorting device.
This method has an excellent effect in that good de-sorting can be continued at all times.

In addition, the de-sorting equipment and the circulating rice milling equipment are communicated, and during the de-sorting work, the circulating rice milling equipment is effectively used for transporting and storing the de-sorted brown rice, and when necessary, the de-sorting work can be interrupted. The original rice milling work can be performed using the circulation type rice milling device.

Therefore, since a conventional grain lifting device is not required, operation can be performed with small power, and manufacturing and operating costs can be reduced.

In addition, the de-sorting equipment and the rice milling equipment are provided separately as separate devices, and are not integrated into one.Furthermore, the de-sorting work and the rice polishing work are performed separately. In both the sorting work and the rice milling work, the same power is used to rotate the rice milling rolls and utilize the suction action of suction blades fixed to the removal shaft. Therefore, there is no need to switch the power for each task.

Furthermore, switching between each task can be easily done by simply operating the resistance handle using a special interlocking mechanism. Therefore, there is no need for a complicated power transmission device and power switching using a complicated pulley body near the power as in the past, and the operation is extremely simple and safe with no erroneous operation.

On the other hand, there is a known rice removing machine that incorporates a removing device and a sorting device into a circulating rice milling machine. It is used as a tank. For this reason, the tanks are built high considering the bulk of the paddy, which is very inconvenient to work with, and
There is a drawback of uneven pumping due to insufficient circulation within the tank. In addition, the skin of brown rice tends to become slippery.

In contrast, the rice milling machine according to the embodiment of the present invention uses separate paddy tanks for removal and brown rice tanks for milling, and furthermore, the discharge port for the removed brown rice faces the roll chamber of the rice milling device. , the paddy tank can be placed in a low position, the operation is easy, and the machine can be made compact. Also,
Since the brown rice tank of the circulating rice milling device can be made low in height, circulation within the tank can be carried out smoothly and there is almost no risk of uneven grinding. In addition, the brown rice does not shift as described above.

Furthermore, the rice polishing machine according to the embodiment of the present invention can of course be used independently as a huller or a rice polishing machine.
