Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a feed rate adjustment device in a vertical rice mill.

(Prior Art) Conventionally, the amount of brown rice supplied in a small vertical rice milling machine was adjusted by opening and closing a control plate provided in a supply hopper.

(Problem that the invention aims to solve) However, even if the opening and closing of the adjustment plate is adjusted, in the case of a small vertical rice mill, the action of the feed spiral by the helix takes priority and stable continuous supply is not possible. Fine adjustment of the amount was not possible.

That is, if it is made smaller, the total supply amount will be reduced, and brown rice or the like will clog at the inlet and block the passage.

(Means for Solving the Problem) Therefore, the present invention provides a supply flow rate adjustment device that can be used in a small vertical rice milling machine to provide a stable supply amount. A grain feeding spiral 2 is provided, a cone 3 with a small diameter at the top is provided at the upper end of the rice milling roll shaft 1, a flow rate adjustment tube 4 is provided on the outer periphery of the cone 3, and the flow rate adjustment tube 4 is connected to the machine frame 7 of the rice milling machine.
A horizontal ring 9 is formed on the upper part of the adjustment ring 8, and a horizontal ring 9 is formed at a constant interval on the ring 9.
A plurality of recesses 10 are formed, and balls 11 are placed in the recesses 10.
an inclined groove 13 is formed in the vertical cylinder 12 of the adjustment ring 8, and a fixed bar 14 protruding from the flow rate adjustment cylinder 4 is passed through the inclined groove 13.
The tip of the fixed bar 14 is engaged with a vertical groove 15 on the side of the machine body 7, a handle 16 is attached to the ring 9, and a knob 17 is fixed to the handle 16. This is the configuration of a feed rate adjustment device in a vertical rice mill. This is what I did.

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a rice milling roll shaft, and a grain feeding spiral 2 is provided on the upper part. A cone body 3 is provided at the upper end of the rice milling roll shaft 1. Although not shown, a pulley is attached below the rice milling roll shaft 1, and this pulley is connected to a motor to rotate the rice milling roll shaft 1. Reference numeral 4 denotes a flow rate adjusting cylinder, the upper half of which is formed into a cylinder 5, and the lower part formed into a funnel 6. The flow rate adjustment cylinder 4 is fitted inside a control ring 8 fitted to the machine frame 7 of the rice milling machine so as to be horizontally rotatable. The adjustment ring 8 has a horizontal ring 9 formed on its upper part, and a plurality of recesses 10 are formed in the ring 9 at regular intervals.
0 is elastically engaged with the ball 11.

An inclined groove 13 is formed in the vertical cylinder 12 of the adjustment ring 8, and a fixed bar 14 protruding from the flow rate adjustment cylinder 4 passes through the inclined groove 13. engage with.

A handle 16 is attached to the ring 9, and a knob 17 is fixed to the handle 16. Therefore, when the knob 17 is held and the handle 16 is moved from side to side, the adjustment tube 4 does not rotate but simply moves up and down.

The supply cylinder 18 is a supply cylinder provided at the lower part of the vertical cylinder 12, and a gear 19 is loosely fitted into the upper part of the supply cylinder 18. The outer periphery of the gear 19 is a step 20 on the inner surface of the fuselage 7.
The ohm 21 is engaged with the gear 19 so as to be rotatable only.

The upper end of the spring 22 engages with the gear 19 . In addition, 23 is a rod, 24 is a rice polishing roll, 25 is a polishing tube, 26 is a rice polishing chamber, and 27 is a rice bran chamber.

(effect) Next, we will discuss the effect.

Since the present invention has the above-described configuration, when the motor is energized to rotate the rice milling roll shaft 1 and brown rice is fed to the supply hopper, the brown rice falls through the gap between the opening at the lower end of the adjustment tube 4 and the cone 3. The rice is then sent downward by the grain feeding spiral 2, where it is polished and discharged.

When you want to adjust the supply amount, manually move the knob 17 to the left or right.
2 rotates to move the inclined groove 13 left and right. Therefore, the fixed bar 14 fitted into the inclined groove 13
, its tip engages with the vertical groove 15 on the fuselage 7 side,
Since the base is fixed to the adjustment tube 4, the adjustment tube 4 moves up and down to adjust the gap between the funnel 6 at the lower end of the adjustment tube 4 and the cone 3.

During this time, the adjustment tube 4 simply moves up and down, so the adjustment is smooth.

(Effects) Conventionally, the amount of brown rice supplied in a small vertical rice milling machine was adjusted by opening and closing a control plate provided in the supply hopper.

However, even if the opening and closing of the adjustment plate is adjusted, in the case of a small vertical rice mill, the action of the feed spiral by the helical takes priority and stable continuous feeding is not possible, making it impossible to finely adjust the amount of rice to be fed.

That is, if it is made smaller, the total supply amount will be reduced, and brown rice or the like will clog at the inlet and block the passage.

Therefore, the present invention provides a supply flow rate adjustment device that can be used in a small vertical rice mill to provide a stable supply amount. A cone body 3 with a small diameter at the top is provided at the upper end of the shaft 1, a flow rate adjustment cylinder 4 is provided on the outer periphery of the cone body 3, and the flow rate adjustment cylinder 4 is connected to the machine frame 7 of the rice milling machine.
A horizontal ring 9 is formed on the upper part of the adjustment ring 8, and a horizontal ring 9 is formed at a constant interval on the ring 9.
A plurality of recesses 10 are formed, and balls 11 are placed in the recesses 10.
an inclined groove 13 is formed in the vertical cylinder 12 of the adjustment ring 8, and a fixed bar 14 protruding from the flow rate adjustment cylinder 4 is passed through the inclined groove 13.
The tip of the fixed bar 14 is engaged with a vertical groove 15 on the side of the machine body 7, a handle 16 is attached to the ring 9, and a knob 17 is fixed to the handle 16. This is the configuration of a feed rate adjustment device in a vertical rice mill. When the motor is energized to rotate the rice milling roll shaft 1 and brown rice is supplied to the supply hopper, the adjustment cylinder 4
Brown rice falls from the gap between the opening at the lower end and the cone 3, is sent downward by the grain feeding spiral 2, is polished and discharged, but if you want to adjust the feed amount, turn the knob 17.
When manually moved left and right, the vertical tube 1 rotates, moving the inclined groove 13 left and right, and the inclined groove 13
The tip of the fixed bar 14 that is fitted into the body 7 engages with the vertical groove 15 on the body 7 side, and the base is fixed to the adjustment tube 4, so the adjustment tube 4 moves up and down, and the adjustment tube 4
This is to adjust the gap between the funnel 6 at the lower end and the cone 3. During this time, the adjustment cylinder 4 simply moves up and down, so the adjustment is smooth.
