Description

[Detailed Description of the Invention] The present invention relates to a device for discharging rice husks and rice sugar in a rice removing machine equipped with a removing device, a rice husk sorting device, and a circulating rice milling device.

This type of general-type rice de-milling machine performs de-sorting and rice-polishing operations alternately, so rice husks are discharged during de-sorting and rice sugar is discharged during rice-polishing. In this kind of rice milling machine,
The route for discharging rice husks and the route for discharging rice sugar were constructed separately, and both routes were equipped with suction and discharge devices, making the built-in devices complex, making the aircraft large, and requiring large amounts of power. There were some shortcomings such as:

Therefore, the present invention combines the route for discharging rice husks and the route for discharging rice sugar into one route, and
The purpose is to use both suction and discharge devices in common, and even if they are used in this way, an appropriate suction force is applied to both channels, that is, the rice husk air path and the sugar removal hose.

Next, embodiments of the present invention will be described based on the drawings.

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

The removing device A is provided on the upper part of the machine body 1, and the removing device main body 3 is provided below the paddy discharge port of the paddy tank 2.
The demasher main body 3 is provided with a paddy shutter 4 for opening and closing the paddy intake port, and is biased in the closing direction by a spring 5. Reference numeral 6 denotes a paddy shutter operating rod, which is formed in a dogleg shape, with its middle portion pivotally attached to a part of the body 1, and its upper portion connected to the paddy shutter 4. 7 is formed into a dish-like shape by being removed from the disk, and a removal rubber 8 is attached to the inner circumferential surface thereof, and this removal from the disk 7 is covered with a removal cover 9. A removal pulley 11, a removal screw 12, and a rotary disk 7a are attached to the removal shaft 10, and the tip of the removal shaft 10 is attached to a removal cover 9.
It protrudes into the suction/discharge case 13 through the suction blade 14, and a suction blade 14 is attached to the protrusion.

The suction and discharge case 13 communicates with the rice husk sorting device B, which is next to the removal device A, through a chaff air passage 15 and a suction chute 16 so as to be able to suction the rice husks, and the discharge side of the suction and discharge case 13 is connected to the rice husk sorting device B, which is connected to the rice husk sorting device B, through a chaff air passage 15 and a suction chute 16. It communicates with the cyclone 18 outside the fuselage 1.

The sorting case 20 of the rice husk sorting device B has a bottom formed low toward the brown rice discharge port 21 in the center, and a brown rice and rice husk discharge port 19 provided in the unpolished rice removal cover 9 on one side is opened obliquely toward the brown rice discharge port 21. A net-equipped air intake port 20a is provided at the bottom between the discharge port 19 of the unpolished rice removal cover 9 and the brown rice discharge port 21, and is inclined from the discharge port 19 to the discharge port 21. A number of inclined plates 22 are provided inside the sorting case 20 so that the brown rice and (rice husk) are sorted by the wind generated by the suction blades 14. A second port 23 is provided at the lower end. 24 is the second port 23.
This is a valve that uses suction to seal the valve.
The rice husks blown up inside the duct 1 are blown into the upper end of the duct 1.
The brown rice is sucked from the rice feeder 5 through the suction chute 16 into the suction discharge case 13, and the brown rice is discharged from the brown rice discharge port 21 at the lower end.
It then flows into the rice polishing roll chamber 25 below.

In the circulation type rice milling device C, a sugar removal outlet 27 with a wire mesh is provided near the front end of the rice mill main body 26, and a sugar removal hose 28 is attached to the outlet 27 via a sugar chute 28a. The distal end of the suction chute 16 is connected to the suction side end portion of the suction chute 16 .

The suction side end of the suction chute 16 is connected to the suction discharge case 13 so as to cover the suction hole 29 thereof,
A partition plate 32 is provided inside to separate the intake holes 29, and the intake holes 29 are connected to a rice husk suction port 30 and a rice sugar suction port 31.
It is divided into appropriate proportions.

In the conventional discharge device of this kind, the suction discharge case 13
Since the partition plate 32 was not provided in the suction section of the rice husk, the suction force of the suction blades 14 between the rice husk sorting device B and the rice milling device C would interfere with each other, for example, during the descaling operation. In this case, the overall air volume decreases due to the high intake negative pressure in the rice husk sorting device B section, and the intake air amount to the rice milling device C side decreases, causing clogging of the wire mesh at the sugar removal outlet 27, and vice versa. This clogging causes further damage to rice husk sorting equipment B.
This resulted in the inconvenient result of increasing the suction pressure to the side and suctioning and discharging the brown rice along with the rice husks from inside the sorting case 20. However, in the discharge device of the present invention, the suction force by the suction blades 14 is applied to the rice husk suction port 30 and the rice sugar suction port 31 individually due to the presence of the partition plate 32, so that the suction force is applied to the rice husk sorting device B and the rice milling device. It is possible to prevent troubles such as interference between the suction force and C.

In addition, at the bottom of the brown rice tank 33 of the rice milling device C,
A rear inverted upper plate 34 is provided to guide the circulation of brown rice,
A resistor 35 protrudes from the front part of the upper plate 34, the resistor 35 is mounted on a shaft in the brown rice tank 33, and a resistance handle 37 and a resistance link 38 are attached to the externally protruding portion of the shaft 36 and rotate together with the resistor 35. It is installed to do so. Among them, the resistance connecting rod 38 is configured to press the lower end of the paddy shutter operating rod 6 of the paddy removing device A backward when it falls backward.

39 is a motor, and a belt 41,
42 is hung.

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

When the motor 39 starts operating, the removing device A,
Rice husk sorting device B and rice milling device C operate together,
The suction force generated by the suction blades 14 in the suction/discharge case 13 reaches both the rice husk air passage 15 side and the sugar removal hose 28 side. Then, if the resistance bundle 37 is lifted and moved to the solid line side, the resistor 35 in the rice polishing device C is set to "weak" and rice milling is not performed, but the resistance link 38 is linked with the resistor 35. As it falls backwards and presses the lower end of the paddy shutter operating lever 6 backward, its upper end rotates forward and opens the paddy shutter 4 against the elasticity of the spring 5.
De-sorting work is carried out, and the rice husks that have been sorted into brown rice pass through the air passage 15 and the suction chute 16, enter the suction outlet 30 into the suction discharge case 13, and are discharged from there through the air passage 17 and the cyclone 18 to the outside. Ru.

Since rice milling is not being carried out at this time, the discharge of rice sugar is not carried out, but the brown rice that has been separated from the rice husks in the rice husk sorting device B enters the rice milling roll chamber 25 through the discharge port 21 at the lower end, and is transferred to the rice milling roll chamber 25. 43, and is pushed up from the front end where the resistor 35 is set to "weak" into the brown rice tank 33 and stored there.

Next, when the resistor bundle 37 is pushed down and operated toward the chain line side, the resistor 35 is set to "strong" so that rice can be milled. On the other hand, since the resistance linking rod 38 comes off from the lower end of the paddy shutter operating rod 6, the paddy shutter 4 closes due to the restoring force of the spring 5, the sorting operation is stopped, and brown rice is no longer supplied to the rice milling roll chamber 25. The brown rice stored in the brown rice tank 33 begins to circulate between the tank 33 and the rice milling roll chamber 25, and the rice is milled. The rice sugar removed from the brown rice passes through the sugar removal hose 28 and enters the suction/discharge case 13 from its suction port 31, and is discharged from there through the air path 17 and the cyclone 18 to the outside.

As described above, this invention is based on a circulating rice removal machine, in which a partition plate that divides the intake hole is provided in the suction section of the suction and discharge case in which suction blades are installed, and the suction and discharge case is communicated with the rice husk sorting device. Because the rice husk suction port and the rice sugar suction port communicating with the rice milling device are opened independently from each other by the partition plate,
There is no interference between the suction force between the rice husk sorting device and the rice polishing device, and a constant suction force is always applied to both devices. This has the remarkable effect of preventing such troubles and ensuring that rice husks and rice sugar can be suctioned and discharged in the same manner as if separate suction and discharge cases were provided.
