Description

[Detailed Description of the Invention] The present invention relates to a circulation type deweighing rice milling machine that includes a deweighing device, a rice husk sorting device, and a circulation type rice polishing device.

This kind of general circulation type deweighing rice milling machine performs deweighing and sorting work and rice milling work alternately, and when performing deweighing and sorting work, the paddy shutter below the paddy tank is opened at the same time.
If the resistor of the rice milling equipment was set to ``weak'' and rice milling work was to be performed, it was necessary to set the resistor to ``strong'' and close the paddy shutter at the same time.

Since the rice shutter and the resistor are switched separately in this way, the switching operations are often made incorrectly, which may cause problems in operation or place an excessive load on the motor.

Therefore, the purpose of this invention is to make it possible to operate the resistor of the rice polishing device and the paddy shutter of the deweighing device in a single operation in a circulating type deweighing rice mill.

Next, an embodiment of this invention will be described based on the drawings.

Figure 1 is a partially cutaway front view of the rice milling machine according to the present invention with the front wall removed, and Figure 2 is a partially cutaway view of the rice milling machine with the side wall removed and the scale removal device and circulating rice milling device cut away. FIG.

A weighing device A, a rice grain sorting device B, and a circulating rice milling device C are built into the same machine body 1.

The deweighing device A is built in the upper part of the machine body 1, and the deweighing device main body 3 is provided below the paddy discharge port of the paddy tank 2.

The deweighing machine main body 3 is provided with a paddy shutter 4 for opening and closing its cutting inlet, and is biased in the closing direction by a spring 5.

Reference numeral 6 denotes a rice shutter operating rod, which is shaped like a dogleg and whose middle part is pivotally connected to a part of the body 1, and whose upper end is connected to the rice shutter 4.

In addition, a part of the deweighing machine shaft 7 inside the deweighing machine main body 3 is attached to a suction case 8.
The suction blade 9 protrudes inward, and a suction blade 9 is attached to that part.

The suction case 8 communicates with the rice husk sorting device B, which is next to the husking device A, through a chaff air passage 10 and a ventilation case 11 so that the rice husks can be suctioned, and the discharge side of the suction case 8 is connected to the air passage 1.
2 communicates with a cyclone 13 outside the fuselage 1.

Furthermore, the rice husk sorting device B is provided with several types of swash plates 14 at appropriate intervals inside, and the rice husk discharge port thereof communicates with the suction case 8 as described above, but the brown rice discharge port 15 is connected to the circulation type rice milling device C below. The opening is at the rear of the rice milling roll chamber 16.

In the circulation type rice milling device C, a bran removing outlet 18 with a wire mesh is provided near the front end of the rice milling machine main body 17, and a bran removing hose 20 is attached to the outlet 18 via a bran chute 19. The tip of the ventilation case 11 is connected to a place where it communicates with the rice husk air passage 10, and a wind direction handle 21 is connected to the connection part.
A wind direction valve 22 that operates in reverse by the switching operation is installed inside,
The communication path can be switched to the rice husk air path 10 side or the bran removal hose 20 side.

Further, at the bottom of the brown rice tank 23 of the rice milling machine C, a rear-inverted upper plate 24 for guiding the flow of brown rice is provided, and a resistor 25 protrudes from the front part of the upper plate 24. A resistance handle 27 and a resistance link 28 are attached to an externally projecting portion of the shaft 26 so as to rotate together with the resistor 25.

Among them, the resistance connecting rod 28 is configured to press the lower end of the rice shutter operating rod 6 of the frame removing device A backward when it falls backward, and one end of the wind direction switching operating rod 29 is attached to the lower end of the rice shutter operating rod 6. 7. The other end is connected to the wind direction handle 21.

Reference numeral 30 denotes a motor, and belts 33 and 34 are connected between the scale remover pulley 31 and the rice miller pulley 32, respectively.

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

When the motor 30 starts operating, the deframing device A, the rice husk sorting device B, and the rice milling device C operate simultaneously.

Next, lift the resistance handle 27 and move it to the solid line side.
In the rice polishing device C, the resistor 25 is set to "weak",
Although rice milling is not performed, the resistance linking rod 28 moves backward in conjunction with the resistor 25 and presses the lower end of the paddy shutter operating rod 6 backward, so its upper end rotates forward. The rice shutter 4 is opened against the elasticity of the spring 5.

At the same time, the lower end of the rice shutter operating rod 6 turns the wind direction handle 21 using the wind direction switching operating rod 29, the wind direction valve 22 opens the rice husk air passage 10, and closes the bran removing hose 20.

Then, with the paddy shutter 4 open, the unhulling and sorting work is performed, and the brown rice that has been sorted from rice husks enters the rice milling roll chamber 16 through the brown rice discharge port 15, is sent by the rice milling roll 35, and the resistor 25 is set to "weak". The brown rice is pushed up into the brown rice tank 23 from the front end which is marked ``'' and stored there.

Further, as described above, the airflow direction valve 22 closes the rice bran removal hose 20 and opens the rice husk air passage 10, so that the suction blade 9 inside the suction case 8
Since the suction caused by the air flow reaches the rice husk sorting device B, the rice husks separated from the brown rice enter the suction case 8 through the chaff air passage 10 and the ventilation case 11, and from there, through the air passage 12 and the cyclone 13 to the outside. released.

Next, push down the resistance handle 27 and move it to the chain line side.
The resistor 25 is set to "strong" to enable rice polishing.

On the other hand, as the resistance connecting rod 28 comes off from the lower end of the paddy shutter operating rod 6, the paddy shutter 4 is closed by the restoring force of the spring 5, the deframing and sorting work is stopped, and the brown rice is stored in the rice milling roll chamber 16.
Therefore, the brown rice already stored in the brown rice tank 23 begins to circulate between the tank 23 and the rice milling roll chamber 16, and rice milling is performed.

In addition, the lower end of the rice shutter operating rod 6 pulls the wind direction switching operating rod 29 due to the restoring force of the spring 5, and the wind direction valve 22 is moved to the rice husk air path 10.
Since the rice bran that has entered the rice bran removal hose 20 due to rice milling is transferred to the ventilation case 1, the suction force is applied only to the rice bran removal hose 20.
1, enters the suction case 8, and from there passes through the air path 12 and is discharged from the cyclone 13 to the outside.

As explained above, the present invention uses a spring to urge the paddy shutter in the closing direction to open and close the cutting entrance of the deframing device, and presses the paddy shutter operating rod onto the shaft of the resistor against the elasticity of the spring. Attached is a resistance link that is integrally attached, and the interlocking mechanism consisting of this resistance link, paddy shutter operating lever, and resistance handle allows the paddy shutter to open or close when the resistance of the resistor is "weak". ” so that it becomes “closed”,
An appropriately small motor can be used, and this type of rice polishing machine can be provided at a low cost.

Further, even if the rice shutter is energized by a spring in the direction to open the rice shutter, the rice shutter, the resistor, and the wind direction valve may be linked to each other.
