When the clutch lever 25 is positioned at the neutral position of the guide hole 37 as shown in FIGS. Roll 5 Polished Rice Roll 6
The attached rotating shaft 7 freely rotates within the boss of the pulley 31, and only the rice polishing device a is driven.

Therefore, when unweighing paddy, the clutch lever should be
25 is lifted and positioned at the deweighing position of the guide hole 37,
As the clutch pin 23 moves backward and a clutch consisting of this and the clutch pawl 32 is engaged, power is transmitted from the pulley 21 to the rotating shaft 57.67 of the weighing device via the pulley 31 belt 59.70 and the pulley 58.69. The feeding roll 56 of the rotating shaft 57 and the rotary disk 77 of the rotating shaft 67
The auxiliary impeller 78 and the impeller 100 rotate, and the supply section 5 is connected to the removal scale cylinder 71 with the cover 73 and the blow-up side 99, respectively.
Air is sucked in from the air intake port 55 of No. 1 and the rear wall opening of the blow-up side 99, and the air is blown up.

Therefore, if the brown rice tank 36 is covered with a lid 110 and the front tube 103 is closed with the switching valve 104 as shown in FIG. The air enters the upper air passage 94 from the blow-up passage 82 of the device C, and then changes its traveling direction diagonally downward along the guide plate 85 and the adjustment plate 86 and hits the middle part of the sorting net 89, where some of the air is repelled. In the upper air passage 94, a part of the air passes through the mesh of the sorting net 89, proceeds in the lower air passage 95 to the tip side of the sorting machine main body 79, and is blown out of the machine from the front cylinder 97. .

On the other hand, the wind inside the blow-up cylinder 99 enters the blow-up cylinder 101 from its outlet, and its main flow rises inside the blow-up cylinder 101, enters the brown rice tank 36 through the front cylinder 102, and is blown out of the machine from the overflow gutter 107. At the same time, a portion of the air in the overflow gutter 107 is blown into the tip of the upper air passage 94 through the ventilation pipe 108 and above the adjustment plate 86, and is combined with the wind passing through the air passage 94.

At the same time, a part of the wind blown into the blow-up tube 101 rises inside the brown rice flowdown gutter 84, enters the lower air passage 95, and combines with the wind passing through the air passage 95.

Therefore, paddy is supplied to the paddy tank 52, and the opening/closing plate 53 is opened appropriately using the operating lever 54, and the feed adjustment plate 60 is rotated using the adjustment handle 66 to appropriately adjust the gap between this and the feed roll 56. Then, the paddy in the paddy tank 52 is sequentially dropped into the supply section 51 from the lower mouth of the tank 52 and transferred to the feed roll 56.
It is fed into the weighing machine main body 50 from between the feeding roll 56 and the feeding adjusting plate 60, and the feeding roll 68 removes the scale from the weighing cylinder 71.
At the same time, the paddy is violently collided with the deweighing conical ring 72 due to the centrifugal action of the blades 76 of the rotary disk 77, and approximately 85 to 90% of the paddy is deweighed.

At the same time, the mixture of brown rice that has been deweighed, partially undeweighed paddy, rice husks, etc. is moved from the blow-up passage 82 to the upper air passage by the lifting action of the blades 76 of the rotary disk 77 and the wind in the deweighing barrel 71. 94 and change the traveling direction along the guide plate 85 and adjustment plate 86.

Therefore, use the handle 88 to adjust the rotation of the adjustment plate 86 as appropriate, and operate the nut 93 to move the sorting net 89 to the support shaft 90.
When the inclination is adjusted by moving up and down using the fulcrum as a fulcrum, the mixture of brown rice, partially unweighed paddy, rice husk, etc. moving along the adjustment plate 86 hits an appropriate position in the middle of the sorting net 89, and the mixture is Most of the brown rice and some of the rice husks inside pass through the mesh of the sorting net 89 and reach the lower passage 95, and the unhulled paddy, etc. and most of the rice husks are received by the sorting net 89, and the rice husks are The paddy and brown rice are separated by the wind passing through the upper passage 94 and blown into the front tube 97 together with the wind.

On the other hand, the mixture of brown rice gradually flows down on the sorting net 89 and is sorted by the sorting net 89, the brown rice in the mixture falls through the mesh of the sorting net 89 and reaches the lower passage 95, and the paddy is separated from the sorting net 89. From the base end to the top of the partition plate 81 and the bottom gutter 83 for paddy flow
It returns to the lower mouth of the paddy tank 52 to combine with the paddy in the tank 52, and then reaches the deweighing barrel 71 from the deweighing machine main body 50 again to receive the deweighing action.

Further, the mixture of brown rice and rice husks that has reached the lower passage 95 is sorted by the wind passing through the lower passage 95 while falling in the lower passage 95 and while the brown rice is flowing down on the flow plate 96.
The brown rice is further sorted by the wind rising inside the brown rice flow down gutter 84 while descending, and the sorted rice husks are blown into the front tube 97 together with the sorting wind and blown away from the upper air passage 94. The brown rice is combined with the incoming rice husks and blown out of the machine, while the brown rice is blown up from the top of the downflow plate 96 through the brown rice flow gutter 94 into the blow-up tube 101, and the blowing direction is regulated from the front tube 102 of the blow-up tube 101. It is blown into the brown rice tank 36 through the gutter 109 and accumulates there.

At this time, if the brown rice in the brown rice tank 36 is filled up to the lower edge of the inlet of the overflow gutter 107, the excess brown rice that is subsequently blown into the brown rice tank 36 flows down from the overflow gutter 107 to the outside of the machine and is discharged.

In addition, when the lever 106 is operated backward to close the front cylinder 102 using the switching valve 104 and perform the deweighing operation, the brown rice blown up in the blow-up cylinder 101 can be directly discharged from the front cylinder 103 to the outside of the machine and taken out. can.

Next, when performing rice polishing work, if the clutch lever 25 is lowered and positioned at the rice polishing position of the guide hole 37, the clutch pin 23 moves forward and the clutch consisting of the clutch pin 23 and the clutch pawl 32 is disengaged and the clutch lever 25 is moved to the pulley 31. The power transmission is cut off, and the operation of the weighing device connected to it stops.

On the other hand, the closing plate 33 moves forward and its hole 35 matches the brown rice intake port of the rice polishing machine main body 2, and the brown rice intake port is opened, so that the brown rice in the brown rice tank 36 sequentially falls into the rice milling machine main body 2. It is force-fed into the sugar removal net 4 by the feed roll 5.

Therefore, by appropriately operating the handle 15 to adjust the pressure applied by the resistance plate 11, the brown rice fed into the sugar removal net 4 is milled by the rice polishing rolls 6, and the sugar is removed. The polished rice leaks from the sugar removal net 4 and is pushed out from the discharge port 8 onto the discharge gutter 20 while pushing open the resistance plate 11 and taken out of the machine.

Note that the blow-up side 99 may be provided at a different position from the scale removing barrel 71, and the power may be transmitted to the rotating shaft of the impeller 100 by a transmission mechanism.

In addition, instead of the clutch-equipped pulley 21, 31 consisting of the clutch pin 23 and clutch pawl 32, an intermediate shaft is installed at an appropriate position, and the intermediate shaft and the driving shaft of the motor 38 are connected by a transmission mechanism. and the rotating shafts 7 and 57.67 of the deweighing device are respectively connected by a transmission mechanism with a clutch mechanism, and by engaging and disengaging the clutch with the clutch lever, the rice polishing device a or the deweighing device can be arbitrarily connected. The same effect can be achieved even if the power is transmitted to the motor to drive them.

Instead of the pawl clutch mechanism consisting of the clutch ring 22 with clutch pin 23 and the clutch pawl 32, the frame removal machine drive pulley 31 is fixed to the rotating shaft 7, and the frame removal machine drive pulley 31, feed drive pulley 58, and removal drive pulley 31 are fixed to the rotating shaft 7. Frame root pulley 6
A tension pulley is attached to the belt 59.70, and a tension clutch mechanism is provided to tension or loosen the belt 59.70 by actuating the tension pulley with a clutch lever. Good too.

In this invention, the frame-removing rice milling machine is constructed as described above, and the frame-removing sorting device, its paddy tank, rice milling device, brown rice tank, and motor are installed in the box-shaped body of the machine, and they are integrated to form the entire machine. In addition to being easily and compactly constructed and convenient for work and handling, it also allows for continuous de-framing sorting and rice milling work, and the rice polishing device and de-framing device inside the box-shaped machine. The upper space was used to install the brown rice tank of the rice milling equipment and the paddy tank of the deframing equipment.
A large brown rice tank and paddy tank will be installed within the space.

Furthermore, since the rice milling device and the de-framing device are driven separately by switching the clutch mechanism, for example, de-framing and rice milling operations can be performed in the same machine by using a motor that drives only the rice polishing device. In addition to being able to increase efficiency with a high horsepower motor, the de-framing sorting device and rice milling device are housed in the same machine and work with them separately, making handling convenient and improving work efficiency. Since the motor is not subject to the load of driving other machines, the motor can be started easily.

Moreover, since the height of the machine can be made low, work such as loading paddy into the paddy tank can be done easily and it is convenient to handle and operate.The structure is simple and can be manufactured easily and inexpensively, and its operation is easy. It has the effect of being smooth and accurate.
