Description

[Detailed description of the invention] The present invention is a de-weighing and rice-polishing machine in which a de-weighing machine and a rice-polishing machine are installed inside the machine, and the de-weighing work and rice-polishing work can be selectively operated using a clutch lever. A stop bar related to a stopper installed on the paddy supply opening/closing plate of the weigher is connected to the clutch lever that connects and disconnects power to the weigher, and when the clutch lever is in the weigher removal position. In addition to driving the unweighing machine, the paddy supply opening/closing plate can be opened and closed, for example, by using the clutch lever mentioned above.
When the clutch of the deweigher is turned off by the operation of the deweigher, the paddy supply opening/closing plate of the deweigher is opened during rice milling operation when the operation of the deweigher is stopped, or conversely, during deweighing operation with the clutch engaged.

) A grain lifting machine pulley 45 is attached to the forward protrusion of the wing axle 44 of the machine, and a belt 46 is hung between the pulley 45 and the grain lifting machine driving pulley 8.

Although not shown, the tip of the grain lifting cylinder of the flipping grain lifting machine 42 faces the upper opening of the brown rice tank 10.

Next, its effect will be explained.

When the clutch lever 23 is locked in the intermediate recess at the neutral position of the longitudinal hole 25 and the motor 12 starts operating, the belt 14 is moved from the double pulley 13 of the driving shaft of the motor 12.
A rotating shaft 4 with a feed roll 5 and a grinding rice roll 6 rotates via a pulley 7, and a blade axle 44 with a flip-up impeller is rotated from a pulley 8 of the rotating shaft 4 via a belt 46 and a pulley 45.
rotates, and the rice mill a and the grain lifting machine 42 are driven.

At this time, the clutch pulley 16 is located on the 1 side as shown by the solid line in FIG. 1 and the belt 15 is relaxed, so the scale removal machine is not driven.

In addition, a stopper 32 fixed to the operating rod 30 of the paddy supply opening/closing plate 29 of the unweighing machine and a stop bar 2 of the clutch lever 23 are provided.
6 is in contact with the clutch lever 23 as shown by the solid line in FIG. Even if the operation lever 30 is moved forward, the stopper 32 of the operating lever 30 is in contact with the stop bar 26 and the stopper 32 is prevented from moving forward, so the operating lever 30 is not pulled out, and therefore the paddy supply opening/closing plate 29 is opened. There is absolutely no way that the paddy will be supplied to the scaler main body 27 unless it is removed.

Next, when the clutch lever 23 is lifted as shown by the chain line in FIG. 3 and locked in the recess at the upper end of the vertically elongated hole 25 at the polishing position, the clutch lever 23 is integrated with the shaft rod 20 and rotates around the shaft rod 20 as a fulcrum. The arm rod 22 attached to the shaft rod 20 rotates counterclockwise in FIG. The rice flows into the rice milling machine main body 2 and performs rice milling work.

Even during this rice milling operation, the stop bar 26 provided on the clutch lever 23 is integrated with the clutch lever 23 and rotates upward about the shaft rod 20 as a fulcrum, as shown by the chain line in FIG. 3. Since the clutch lever 23 is held in contact with the stop bar 26 in the same way as when the clutch lever 23 is in the neutral position, the operation rod 30 with the stopper 32 is prevented from moving forward and the paddy supply opening/closing plate of the unweigher is blocked. 29 cannot be opened.

When unweighing paddy, the clutch lever 23 is lowered and locked in the recess at the lower end of the elongated hole 25 at the unweighing position, as shown in FIG. -23
Since the shaft 20 with the attached shaft rotates clockwise in FIG. 4, the brown rice supply opening/closing plate 9 connected to the arm 22 of the shaft 20
moves forward and closes, stopping rice milling.

At the same time, the arm 18 of the shaft 20 is rotated counterclockwise in FIG. , the paddy supply roll 38 deweighing rotary disk 39 rotary shaft 37 with suction windmill 40 is rotated via the belt 15 pulley 11 from the double pulley 13, and preparations are made for deweighing and sorting the paddy. .

On the other hand, as the clutch lever 23 is lowered, the stop bar 26 integrated with the clutch lever 23 rotates downward using the shaft rod 20 as a fulcrum and separates from the stopper 32, so that the operating rod 30 of the paddy supply opening/closing plate 29 can move back and forth. Become free.

Therefore, by pulling out the handle 31, the paddy supply opening/closing plate 29 moves forward and opens via the operating rod 30, and the paddy in the tank 28 is transferred from the cut-off inlet of the deweighing machine main body 27, through the paddy supply roll 38, to the deweighing rotary disk 39. It reaches the point where it hits the deweighing ring 34 and is deweighed.

On the other hand, the unweighed product is blown into the sorter C from the outlet of the unweigher cover 35 by the centrifugal force and wind generated by the unweigher rotary disk 39, and brown rice and rice husks are separated in the sorter main body 41. The rice enters the grain lifting drum 43 from the lower end exit of the sorter body 41 and is thrown up into the brown rice tank 10 by the action of the grain lifter 42, and the rice husks and the like are discharged from the upper end of the sorter body 41 to the outside of the machine body 1.

When the unweighing operation is completed, the handle 31 is pushed in to move the paddy supply opening/closing plate 29 backward and closed, and then the clutch lever 23 is lifted and returned to the intermediate recess at the neutral position of the vertical hole 25, and the operation is completed.

However, if the operator accidentally pushes in the paddy supply opening/closing plate 29 before closing it, that is, lifts the clutch lever 23 with the handle 31 pulled out and returns it to the intermediate recess at the neutral position of the vertical hole 25, the clutch lever The tip of the stop bar 26 that rotates upward together with the stop bar 23 is the stopper 32.
, the clutch lever 23 is prevented from rising.
Such erroneous operations never occur.

In addition, instead of providing the stopper 32 on the operating rod 30 connected to the paddy supply opening/closing plate 29, the paddy supply opening/closing plate 29 is formed to protrude long forward, and the front protrusion of the paddy supply opening/closing plate 29 is The stop bar 2 is located opposite the stop bar 26 of the
6 is bored in and out of the hole, and only when the stop bar 26 locks in the lower end recess at the escape position of the vertically long hole 25, the stop bar 26 is configured to be pulled out from the hole in the paddy supply opening/closing plate 29, Even if the paddy supply opening/closing plate 29 also functions as the stopper 32, it functions in the same manner as described above.

In the present invention, the device for preventing erroneous operation in the de-weighing rice milling machine is configured as described above, so the clutch lever is positioned at the de-weighing position and the clutch of the transmission mechanism to the de-weighing machine is engaged to drive the de-weighing machine. Only when the stop bar of the stopper of the paddy supply opening/closing plate separates from the stopper and the paddy supply opening/closing plate becomes movable, the paddy supply opening/closing plate can be moved and opened to perform the unweighing operation, and on the other hand, When the operation of the scaler is stopped by turning the clutch lever and disengaging the clutch of the transmission mechanism to the scaler, the stop bar comes into contact with the stopper of the paddy supply opening/closing plate and the paddy supply opening/closing is stopped. The plate is held closed.

Therefore, mistakes in the operation of the clutch lever and the paddy supply opening/closing plate are completely prevented, making handling easier and allowing the worker to work with peace of mind.Also, the unweighing and sorting work can always be carried out well, increasing work efficiency. Furthermore, the structure is extremely simple and can be manufactured easily and inexpensively, and the connection is reliable and strong.
