Description

Description: TECHNICAL FIELD The present invention relates to a hard-axis rice milling machine that supplies brown rice from the lower part of a whitening chamber to whiten it and discharges it from the upper part.

[Conventional technology]

In the conventional hard-axis rice milling machine, when the degree of whitening is increased during polishing, the flow resistance of the rice grain is increased by using a whiteness adjusting device provided above the outlet of the whitening chamber. In order to increase the resistance, the ability to suppress the rice grains from the whitening chamber is increased, which reduces the ability of the spiral trousers to pump the rice grains, which in turn lowers the processing ability of milled rice.

A hollow upper feeding screw conveyor shaft is concentrically connected to the upper part of the white trochanter, and a connecting rod is slidably fitted to the screw conveyor shaft so that the lower part of the connecting rod is the white rice discharging part. The upper part of the resistance plate is connected to a compression degree adjusting device for adjusting the pressure of the resistance plate to form a hard axis type rice milling machine. Then, the minimum inner diameter of the polygonal cylinder in which the white trochanter is installed is formed to be larger than the inner diameter of the cylinder in which the spiral trochanter is installed, and a bottom wall is provided at the boundary between the cylinders.

[Work]

Rice grains supplied to the spiral trochanter from the brown rice supply unit of the hard-axis rice mill are lifted by the spiral trochanter against the resistance of the resistance plate, and the main part is the perforated wall degreasing whitening barrel and whitening trochanter.

The pulley 16 and the pulley (not shown) of the blower 17 are connected by a V level 18, and the sugar discharge port 19 of the blower 17 is connected to the cyclone 21 via the sugar discharge pipe 20. Reference numeral 22 is an intake port, reference numeral 23 is a blowout port, and the sugar removal chamber 24 communicates with the blower 17 via a sugar removal duct (not shown).

Reference numeral 25 denotes an upper conveyor, which fits the lower end of a hollow screw conveyor shaft 27, around which the spiral 26 is wound, with the upper end of the friction polishing trochanter 6 and connects it with a connecting pin 28.
Fit the upper end of the bearing 29 to the bearing 29. A connecting rod 30 is slidably fitted to the conveyor shaft 27, and the lower portion of the connecting rod 30 is connected to a resistance device 49 provided at the white rice discharge port 9 by a connecting pin 31. Resistance device
49 is composed of a cylindrical body 51 formed by winding a spiral body 50 of the resistance plate 32,
Further, reference numeral 33 is a slot-like void provided in the conveyor shaft 27, and reference numeral 34 is a buffer spring. The upper end of the connecting rod 30 is connected to the compression degree adjusting device 35. The upper end of the connecting rod 30 is fitted into the bearing 36, the bearing 36 is connected to the adjusting rod 38 via the supporting rod 37, and the reference numeral 39 is an adjusting handle attached to the tip of the adjusting rod 38.

A scraping blade 40 is provided on the upper end of the conveyor shaft 27, and the discharge gutter 42 is connected to the refined product discharge port 41 of the upper transport device 25. Discharge gutter 42

Is in contact with the supply gutter 12 via the return gutter 45, and reference numeral 46 is a window for confirming the accuracy of the rice grain.

Next, the operation of the above configuration will be described. When the motor 14 is driven, the brown rice in the brown rice tank 10 flows down the bottom plate 11 and is sent from the supply gutter 12 to the spiral rotator 4 through the supply port 8. The brown rice is pumped to the whitening chamber 7 by the spiral trochanter 4 and subjected to the polishing action generated by the rotation of the frictional whitening trochanter 6 to be refined. Then, the blower 17 ventilates from the intake port 22 and the sucrose removing air ejected from the blast port 23 performs a saccharification action. Dust such as sugar generated in the smelting chamber 7 due to the polishing action is discharged to the sucrose removing chamber 24 from the through hole of the porous wall sucrose removing and smelting cylinder 2, and the blower 17 and the sugar outlet from the sucrose removing duct (not shown). It is sent to the cyclone 21 via 19 and the sugar scavenger 20 and is collected.

It is discharged to the outside of the machine.

Immediately after the start of polishing, the incompletely polished rice is discharged from the discharge gutter 42, so that the fine reversing motor 43 is operated to reverse the discharge gutter 42 to the position of the chain line to circulate the unpolished rice. That is, the unpolished rice drops from the refined product outlet 41 to the rice collecting trough 44, is sent from the supply trough 12 to the brown rice supply inlet 8 through the return trough 45, and is re-polished. Then, after confirming that the proper lapping accuracy has been reached after a certain period of time through the window 46 and the forward / reverse rotation motor 43 is operated to reverse the discharge gutter 42 to the position of the solid line, the white rice is discharged from the discharge gutter 42 to the outside of the machine. Is discharged.

Next, the operation of adjusting the accuracy of the hammer will be described. Pressure adjustment device 35
When the handle 39 is pushed down, the connecting rod 30 is pushed down via the bearing 36, and the resistance plate 32 is pushed down via the tubular body 51 accordingly. As a result, the pressure in the milling chamber 7 is increased to improve the grinding accuracy, and the polished rice having an appropriate grinding accuracy is sent up by the spiral body 50 of the resistance device 49, and further by the spiral body 26 of the screw conveyor shaft 27. Will be sent to you.
At this time, the spiral body 50 wound around the cylindrical body 51 of the resistance device 49 promotes the upward feeding action and prevents the staying.

As described above, when the compression degree adjusting device 35 is actuated to increase the bowling accuracy, the pressure in the polishing chamber 7 rises, and the pressure on the spiral trochanter 4 portion thereunder also rises. But spiral trochanter 4
Polygonal cylinder in which the cylindrical body 52 and the friction whitening trochanter 6 are installed
The pressure on the spiral rotator 4 is significantly reduced by the bottom wall 54 provided at the boundary with 53. Therefore, the ability to lift the rice grains of the spiral rotator 4 does not significantly decrease due to the adjustment of the hammering precision.

〔The invention's effect〕

According to the hard axis type rice milling machine of the present invention, a hollow upper feeding screw conveyor shaft is concentrically connected to the upper part of the milling trochanter, and the connecting rod is slidably fitted to the screw conveyor shaft. The lower part of the connecting rod is connected to a resistance plate provided in the white rice discharging section, and the upper part is connected to a compression degree adjusting device for adjusting the pressure of the resistance plate. Since the inner diameter of the cylinder in which the child is installed is formed large and the bottom wall is provided at the boundary of each cylinder, the white rice discharge port of the rice polishing machine can be arranged at a high position, and a large-sized polished rice container Since the bottom wall reduces the pressure applied to the spiral trochanter below the whitening chamber, it is possible to prevent the spiral trochanter's ability to pump rice grains from fluctuating significantly by adjusting the lapping accuracy. In addition, it is possible to prevent the deterioration of the polishing processing ability.
