[Detailed description of the invention] (Field of industrial use) The present invention relates to a feed control valve for a rice hulling device.

(Prior art) Conventionally, a feeding control valve is provided at the inlet of the supply hopper of the hulling section to adjust the feeding amount, and a layer thickness control valve for sensing the grain layer thickness is installed inside the cylinder for sorting in the different grain sorting section. In the case where a sensing valve is provided, the sensing valve and the feeding control valve are opened and closed for large loading when there is little grain in the cylinder and small loading when there is a lot of grain in the cylinder. It was related and combined like this.

(Problems to be Solved by the Invention) ,) Therefore, immediately after the start of work, there is no grain in the cylinder, so the feeding control valve opens for large inputs, so a large amount of grain is fed all at once, and work starts. Immediately after, there was a flaw in which the load resistance was intense, causing the motor to stop and the automatic adjustment mechanism to break down.

(Means for Solving the Problem) The present invention improves this point, and includes a feeding control valve 4 for adjusting the feeding amount at the inlet of the supply hopper 3 of the hulling section l, and a dissimilar grain sorting section. A layer thickness sensing valve 28 for sensing the layer thickness of grains is provided inside the sorting cylinder 15 in the cylinder 14, and the sensing valve 2
8 and the feeding control valve 4 are connected in such a manner that the feeding control valve 4 opens and closes for large input when there is little grain in the cylinder 15 and for small input when there is a large amount of grain in the cylinder 15. Immediately after the start of work, even if there is no grain in the sorting cylinder 15, the feeding control valve 4 is opened to a small feeding state,

A rice control valve 42 is installed in the brown rice receiving trough 18 in the different grain sorting section 14.
The finished rice control valve 42 and the feed-in control valve 4 are connected to large input when the finished rice control valve 42 is opened wide because there are few grains in the cylinder 15. When the rice control valve 42 is to be opened to a small extent, the feed control valve 4 is connected so that a small official can open and close it. Reference numeral 4 designates a feed-in control valve of a hulling device which is configured to open in a small amount of input state and automatically open and close to the above-mentioned state after a certain period of time.

Therefore, a layer thickness sensing valve 28 is provided inside the cylinder 15 on the starting end side 17 side. The layer thickness sensing valve 28 is attached to a shaft 29, and when the layer thickness sensing valve 28 moves up and down with the thickness of the flow stack, the shaft 29 rotates. The end of the shaft 29 protrudes outside the machine, and the gear 30 is fixed thereto. The gear 30 has a fan shape,
The intermediate gear 31 meshes with this. Reference numeral 32 denotes a shaft on which the intermediate gear 31 is attached, and when the layer thickness sensing valve 28 moves from the position A to the position C, the intermediate gear 31 rotates by half a rotation via the gear 30. A rod 3 is attached to the upper part of the shaft 32 of the intermediate gear 31.
One end of 3 is pivoted. The other ends of the rows and doors 33 are pivoted to a bell crank 34, and a connecting rod 35 extending to the arm 6 is pivoted to the other end of the bell crank 34.

That is, the rod 33 is in the position A when the layer thickness sensing valve 28 is moved down to the maximum, and is in the position C when it is moved up to the maximum.
In between is the position of the mouth. When the rod 33 is in the A position and the C position, the opening degree of the feed control valve 4 is the smallest, and in the one-port position, the opening degree is the largest.

(Example) In FIGS. 5 to 8, a plurality of layer thickness sensing valves 28 may be provided, and in addition to the layer thickness sensing valve 28 that detects that there are many grains, there is a layer that detects that there are not enough grains.

and are connected via a rod 47. 48 is an operating lever.

(effect) Next, we will discuss the effect.

When unhulled rice is supplied to the supply hopper 3, the hulling roll 2.2
The rice is hulled in the chamber, and then wind-selected in the wind-selecting room 8.The aromatic grains are taken out to the first receiving gutter 11, the second aromatic grains are taken out to the second receiving gutter 13, and the dust is sucked into the suction blower 9. released.

The first object that has fallen into the first receiving gutter 11 is transported by the first compare lO, flows into the starting end side 17 of the cylinder 15, and is passed through the pot hole 16.
The brown rice in the lower layer is scooped up and taken out to the brown rice receiving trough 18, and transferred to the brown rice transfer conveyor 1.
9, the rice is laterally conveyed to the discharge side 21, and falls through the drop opening 20 into the finished rice receiving trough 22, and is taken out of the machine by falling [120]. The unhulled rice remaining in the cylinder 15 overflows from the unhulled rice discharge port 24, is conveyed horizontally by the unhulled rice conveyor 26, and is returned to the unhulled rice return chamber 27 by the thrower to be reprocessed.

Immediately after the start of work, the layer thickness sensing valve 28 descends under its own weight and is at the position A in Fig. 1, so the gear 30 and the intermediate gear 31 are meshed in the state shown in Fig. 1, and therefore the rod 33 is the state shown in FIG. 3, with the rod 33 and the intermediate gear 3
The joint part 1 is located at the position A directly above the shaft 32. When the rod 33 is in this position, the bell crank 34 is in the state shown in FIG.
is opened small and the unhulled rice is fed little by little to the hulling roll 2.2.

1. In other words, immediately after the start of work, the layer thickness sensing valve 28 is at its lowest position, so normally the link mechanism would lower the refill control valve 4.
However, in the present invention, the feed-in control valve 4 is opened small and the unhulled rice is gradually fed to the hulling rolls 2.2.

As the work progresses in this state, grains gradually accumulate on the starting end side 17, and the layer thickness sensing valve 28 is pushed up by the grains and moves from the position A to the opening position. Therefore, the intermediate gear 31 that meshes with the gear 30 also rotates 45 degrees, and the rod 33
moves from the position of the i to the position of the mouth. Therefore, the bell crank 34 is pulled by the rod 33 and rotates, and the connecting rod 3
5, the refill control valve 4 is gradually opened widely.

2 The position of the mouth opens to the maximum, and if the layer thickness sensing valve 28 moves past this point to point C, there will be an oversupply condition. The intermediate gear 31 rotates, the rod 33 is at the same position as A, and the feed control valve 4 is opened slightly.

In the case of Figures 5 to 8, there are two valves, and the layer thickness sensing valve 3
6 is a valve that detects the minimum, and the layer thickness sensing valve 28 is a valve that detects the maximum. Immediately after the start of work, there is no grain at all on the starting end side 17 as described above, but for that reason,
The layer thickness sensing valve 36 is lowered to the maximum extent by its own weight, and the upper end of the arm 38 is rotated counterclockwise in FIG. Then rod 40
slides through the elongated hole 41 formed in the arm 39 and advances further until it hits the inner surface of the elongated hole 41, so the arm 39 is rotated clockwise and the rod 33, bell crank 34, and connecting rod 35 connected to the arm 39 are moved forward. This action causes the refill control valve 4 to open slightly. As the work progresses, the grain slides on the starting end side 17 and pushes the layer thickness sensing valve 36, causing the arm 38 to rotate clockwise in FIG. 6 and move the rod 40 to the right in FIG. Therefore, the rod 40 will be located in the middle of the elongated hole 41, and the arm 39 will be free without being constrained by the rod 40, and will be in a state where it can move freely from side to side.

Therefore, the rod 33 is moved only by the detection of the layer thickness sensing valve 28, and the refill control valve 4 is opened and closed via the bell crank 34.7) and the connecting rod 35.

To explain the case shown in FIGS. 9 to 10, when the operating lever 48 is held and moved upward, the arm 44 fixed to the shaft 43 of the control valve 42 is rotated counterclockwise, thereby opening the control valve 42. .

Then, the rod 4 attached to the lower end of the arm 44
7 to the right, the rod 47 moves within the elongated hole 46 formed in the upper part of the arm 45 and finally hits the inner surface thereof, causing the arm 45 to rotate clockwise.

Therefore, the rod 33, the bell crank 34, the connecting rod 3
5, the feed control valve 4 is opened slightly, and the work is started in this state. As the work progresses, when the arm 39 is moved downward by hand, the rod 47 is located at the center of the long hole 46, and since the arm 45 can freely rotate without being constrained by the rod 47, layer thickness sensing is possible thereafter. As a result of the detection by the valve 28, the replenishment control valve 4 is opened and closed.

(Effects) Conventionally, a feeding adjustment valve is installed at the inlet of the supply hopper in the hulling section to adjust the feeding amount, and a layer thickness sensor is installed inside the cylinder for sorting in the different grain sorting section to detect the layer thickness of the grain. In the case where a valve is provided, the sensing valve and the feeding control valve are opened and closed so that when there is little grain in the cylinder, the feeding control valve opens and closes for a large charge and when there is a large amount of grain in the cylinder, a small charge is made. It was associated with.

Therefore, immediately after the start of work, there is no grain in the cylinder, so the feeding control valve opens when large amounts of grain are fed, so a large amount of grain is fed all at once, resulting in severe load resistance immediately after the start of work, causing the motor to stop. There were also defects that caused the automatic adjustment mechanism to break.

6 The present invention improves this point by providing a feeding control valve 4 for adjusting the feeding amount at the inlet of the supply hopper 3 of the hulling section l, and a cylinder 15 for sorting in the dissimilar grain sorting section 14. A layer thickness sensing valve 28 for sensing the layer thickness of the grain is provided inside the sensing valve 2.
8 and the feeding control valve 4 are connected in such a manner that the feeding control valve 4 opens and closes for large input when there is little grain in the cylinder 15 and for small input when there is a large amount of grain in the cylinder 15. Immediately after the start of work, even if there is no grain in the sorting cylinder 15, the feeding control valve 4 is opened to a small feeding state,
A feeding control valve of the hulling device configured to automatically open and close in the above-mentioned state after a certain period of time, and a feeding control valve 4 for adjusting the feeding amount at the inlet of the supply hopper 3 of the hulling section l are provided. ,
A finished rice control valve 42 is installed in the brown rice receiving trough l8 in the different grain sorting section 14.
The finished rice control valve 42 and the feed-in control valve 4 are set to large input when the finished rice control valve 42 is opened wide because there are few grains in the cylinder 15, and when there are many grains in the cylinder 15 for finishing. - When the L rice control valve 42 is opened small, it is necessary to open and close the charging control valve 4 at a small charge.
Immediately after the start of work, even if there is no grain in the sorting cylinder 15, the loading control valve 4 is opened to a small input state, and after a certain period of time, the rice hulling device is configured to automatically open and close to the above-mentioned state. Since it is configured as a control valve, even if there is no grain in the cylinder immediately after starting work, a large amount of grain will not be fed all at once, and the load resistance will be stable. Prevent defects that could destroy the self-adjusting mechanism.
