Closes when moved downward.

A wide space 58 is formed at the lower part of the storage tank 34 . A frame 59 formed separately from the finished rice elevator 30 is provided in the space 58 so as to be freely inserted and removed.

The frame body 59 has a square shape when viewed from the front, but has a U-shape when viewed from the side. The lower part of the frame 59 is formed into a bag placing part 60, and a pulley may be attached to the lower end thereof. Horizontal shelf 6 at the top of the frame 59
1 is a square frame, and an annular load cell 62 is provided on the upper part of the horizontal shelf 61. The load cell 62 is provided with a measuring tank 63, and the measuring tank 63 is connected to the frame 5.
When the finishing rice elevator 30 is approached by the rice finishing machine 9, the finishing rice elevator 30 is almost located below the opening/closing valve 43.

The upper end of the measuring tank 63 is open, and the part below the center is formed into a funnel part 64, and a lower end outlet 65 is formed.
An on-off valve 66 is provided at the lower part of the valve.

The on-off valve 66 is provided with a handle 67 that projects forward, and when the handle 67 is held and operated, the lower end flow port 65 can be opened. 70 is a grain bag.

Next, we will discuss the effect.

To describe the specific action, first, since the storage tank 34 is empty before the work starts, it moves up to the maximum due to the elasticity of the spring 42, and the load cell 6
Since no load is applied to 2, upper solenoid 4
8. Neither the lower solenoid 46 is energized, so the rod 47 and the rod 49 both extend,
The on-off valve 43 completely closes the discharge port 49.

In this state, when the raw material unhulled rice is supplied to the tensioning hopper 2, the unhulled rice is raised by the tensioning elevator 1 and stored in the fixed hopper 3.

The grain in the fixed hopper 3 is fed out little by little by the rotation of the feeding roll 9, flows on the sink plate 10, is supplied between the hulling rolls 7 and 8, is hulled, and sent to the swinging type spreading device. 14.

Since the swing type spreading device 14 is vibrated diagonally up and down by the eccentric wheel 17, the unhusked grains fall in a state where they are evenly spread in the width direction.
Supplied within 0.

During this time, the air sucked by the suction blower 23 passes through the wind selection chamber 12, passes below the swinging type diffusion device 14, passes through the grains of rice grains falling from the swinging type diffusion device 14, and passes through the wind selection section 13. When rising in the interior, lightweight rice husks are blown away and sorted, and removed from the system by a suction blower 23.

Since the distribution supply gutter 20 moves left and right together with the sorting plate 21, the mixed rice of hulled rice and brown rice is distributed onto the sorting plate 21 of each stage, and is sorted into hulled rice and brown rice, respectively, and the brown rice is discharged. The unhulled rice in the gutter 26 is taken out to the unhulled rice discharge gutter 24. The brown rice discharged into the brown rice discharge gutter 26 is separated from waste rice etc. because the brown rice discharge gutter 26 moves horizontally from side to side together with the sorting plate 21 and because a small foreign matter removal plate 27 is formed on the bottom. The small foreign objects are completely removed, fall into the brown rice input hopper 31 from the brown rice discharge port 28, go up the finished rice elevator 30, and are supplied to the storage tank 34.

When the brown rice stored in the storage tank 34 reaches a predetermined level, hold the grain bag 70 in your hand and apply it to the lower end outlet 65 (in some cases, the upper end is supported by a bag support device). When the switch is turned on in this state, both the lower solenoid 46 and the upper solenoid 48 are energized and the rod 47 is turned on.
and the rod 49 are both pulled up, the arm 45 rotates the on-off valve 43 around the shaft 44 to open the on-off valve 43 to the maximum, allowing the grain stored in the storage tank 34 to be fully loaded. Measuring tank 63
drop it inside.

Therefore, the load cell 62 is connected to the measuring tank 63.
When the weight of the rod 4 reaches a predetermined amount, it sends a signal and de-energizes the lower solenoid 46.
7 extends and rotates the on-off valve 43 about half way. Therefore, the discharge port 49 is closed at the small input notch 68, so that from then on the liquid flows down little by little, and when a predetermined amount is reached, the load cell 62 senses this and de-energizes the upper solenoid 48. The rod 49 is extended and the discharge port 49 is completely closed to complete the measurement.

After measuring, the grain bag 70 is inserted into the lower end outlet 65.
When the handle 67 is operated to open the on-off valve 66, the grains flow into the grain bag 70.

In this case, as the storage tank 34 gradually increases in volume, brown rice overflows from the overflow cylinder 50 and flows into the holding tank 51. When the storage tank 34 becomes lighter, it moves up and down and rotates the arm 56 via the connecting rod 57, so the on-off valve 54 of the holding tank 51 is opened and the holding tank 5
1 gradually flows into the finished rice elevator 30.

On the other hand, when the amount of brown rice in the storage tank 34 increases,
The storage tank 34 moves downward against the elasticity of the spring 42, rotates the arm 56 by the connecting rod 57, and closes the on-off valve 54 of the storage tank 51, thereby preventing any further increase in the amount in the storage tank 34. To prevent.

As described above, the present invention comprises the hulling section 4, the wind sorting section 13 that wind-sorts rice husks, etc., the swing-type sorting section 19 that sorts brown rice and unhulled rice, and the staking system that supplies unhulled rice to the hulling section 4. It has an elevator 1 and a finished rice elevator 30, the tensioning elevator 1 and the finished rice elevator 30 are installed side by side with an interval, a storage tank 34 is provided at the discharge part of the finished rice elevator 30, and the Paddy for farmers, in which a holding tank 51 is provided between the tensioning elevator 1 and the finished rice elevator 30 to hold the brown rice overflowing from the storage tank 34 and supply it to the finished rice elevator 30 when the amount stored in the storage tank 34 decreases. Since the structure of the sliding device is adopted, the holding tank 51 is provided within the space between the tensioning elevator 1 and the finished rice elevator 30, so that not only can the space be skillfully used to configure the entire structure, but also By connecting the lifting machine 1 and the finishing rice lifting machine 30 through the holding tank 51, it is possible to make the tensioning lifting machine 1 and the finishing rice lifting machine 30 more robust and make them part of the strength member.
