Description

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

(Prior Art) Conventionally, a polishing cylinder is known in which the polishing cylinder is formed to rotate diagonally downward when a load is applied, and the polishing cylinder is pulled by a spring. The strength of the known spring is adjusted by attaching its upper end to a manually rotating adjustment plate.

(Problems to be Solved by the Invention) The conventional spring elasticity adjusting device cannot be finely adjusted. In addition, the spring is heavy and difficult to operate due to its considerable elasticity.

(Means for solving the problem) The present invention is an improvement on this point, in which a vertical supply cylinder 18 is provided at the center of the machine frame 7, and the supply cylinder 18 is provided at the center of the machine frame 7.
A vertical polishing tube 25 is connected to the lower end of the feed tube 1.
The lower end of the rod 23 is attached to the outer periphery of the supply cylinder 8 via the lower shaft attachment part 29, and the upper end of the rod 23 is attached to the inner surface of the machine frame 7 by the upper shaft attachment part 30.
A gear 19 is fitted on the outer periphery of the gear 19 so as to be horizontally rotatable. The upper end of the spring 22 is fixed to a shaft, the lower end of the spring 22 is fixed to the supply cylinder 18, and the gear 19 is engaged with an ohm 21, thereby forming a load adjusting device for a vertical rice mill.

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. A pulley 1 is located below the rice milling roll shaft 1.
6 is attached, and this pulley 16 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 the machine frame 7 of the rice milling machine.
On the other hand, it is fitted inside an adjustment ring 8 fitted so as to be horizontally rotatable. The adjustment ring 8 has a horizontal collar 9 at the top.
A plurality of recesses 10 are formed in the horizontal collar 9 at regular intervals, and a ball 11 is elastically engaged with the recesses 10.

An inclined groove 13 is formed in the vertical cylinder 12 of the adjustment ring 8. A fixed bar 14 protruding from the flow rate adjustment cylinder 4 passes through the inclined groove 13, and the tip of the fixed bar 14 is connected to the vertical groove on the body 7 side. 15.

Reference numeral 18 denotes a supply cylinder provided at the lower part of the vertical cylinder 12, and a horizontal gear 19 is loosely fitted into the upper part of the supply cylinder 18. The outer periphery of the gear 19 is the stepped part 2 on the inner surface of the fuselage 7.
The gear 19 is engaged with the gear 19 so that it can only rotate freely, and the ohm 21 is engaged with the gear 19.

The upper end of the spring 22 engages with the gear 19.

The lower end of the spring 22 is fixed to the supply cylinder 18, and when the ohm 21 is rotated and the gear 19 is rotated in the direction of A, the upper end of the spring 22 gradually moves, so the elasticity of the spring 22 gradually becomes stronger. , Therefore, the polishing cylinder 25 is strongly urged in the direction A. The supply cylinder 18 is provided with a lower shaft attachment portion 29, the lower end of the rod 23 is attached to the lower shaft attachment portion 29, and the upper end of the rod 23 is attached to an upper shaft attachment portion 30 attached to the machine frame 7 side. Therefore, as the elasticity of the spring 22 becomes stronger as described above, the inclination of the stepped portion 20 gradually becomes stronger, thereby causing the supply tube 18 to move upward.

A polishing cylinder 25 is attached to the lower end of the supply cylinder 18, and rice polishing rolls 24 are provided concentrically inside the polishing cylinder 25. Between the rice polishing roll 24 and the polishing tube 25 is a rice polishing chamber 26, and the outer periphery of the polishing tube 25 is a bran chamber 27.

Note that 17 is an outlet, 28 is a manual rotation knob 2, and 31 is a pointer.

(effect) Next, we will discuss the effect.

When brown rice is fed from the top, funnel 6 and cone 3
The rice flows into the rice milling chamber 26 through the gap between the rice milling rolls 2 and 2.
Stirred by 4. At this time, when the resistance becomes stronger, the polishing tube 25 rotates in the opposite direction, so the lower shaft attachment part 29 moves in the opposite direction against the elasticity of the spring 22, making the rod 23 vertical. . In this case, since the upper shaft attachment part 30 is attached to the machine frame 7, the lower shaft attachment part 29 will move downward centering on the upper shaft attachment part 30, and the supply cylinder 18 and the polishing cylinder 25 will move downward at the same time. However, since the volume inside the rice milling chamber 26 is increased and the discharge port at the bottom is opened wide, a large amount of rice grains can flow out and be automatically adjusted. In this case, the degree of rice polishing is determined by adjusting the elasticity of the spring 22 to be strong or weak.

That is, if the elasticity of the spring 22 is made strong, the polishing tube 25 will not rotate in the opposite direction even if a considerable load is applied.

However, if the elasticity of the spring 22 is weak, the polishing cylinder 25 will begin to rotate even with a small load, and the volume of the rice polishing chamber 26 will be increased to soften the load, which will eventually reduce the elasticity of the spring 22 to less than It is extremely important to be able to make subtle adjustments.

In the present invention, when the manual rotation knob 28 is rotated, the ohm 21 rotates, and the ohm 21 rotates the gear 19, so that movement in the A direction can be performed very delicately. Furthermore, after the adjustment, the ohm 21 acts to prevent reverse rotation, thereby preventing the gear 19 from rotating naturally.

(Effects) Conventionally, a polishing cylinder is known in which the polishing cylinder is formed to rotate diagonally downward when a load is applied, and the polishing cylinder is pulled by a spring. The strength of the known spring is adjusted by attaching its upper end to a manually rotating adjustment plate.

The conventional spring elasticity adjusting device does not allow fine adjustment. In addition, the spring is heavy and difficult to operate due to its considerable elasticity.

However, in the present invention, a vertical supply cylinder 18 is provided at the center of the machine frame 7, a vertical polishing cylinder 25 is connected to the lower end of the supply cylinder 18, and a lower shaft attachment part 29 is attached to the outer periphery of the supply cylinder 18. The lower end of the rod 23 is attached through the feed tube, and the upper end of the rod 23 is attached to the inner surface of the machine frame 7 via the upper shaft attachment part 30. A gear 19 is fitted to the outer periphery of the supply tube 18 so as to be horizontally rotatable. The outer periphery of the spring 22 is fitted into a stepped portion 20 provided on the inner surface of the machine frame 7 so as to be rotatable only, and the upper end of the spring 22 is pivotally fixed to the gear 19.
The lower end of the spring 22 is fixed to the supply cylinder 18, and the ohm 21 is engaged with the gear 19, so that it is configured as a load adjustment device in a vertical rice mill.
The brown rice supplied from the top flows into the rice milling chamber 26 through the gap between the funnel 6 and the cone 3 and is stirred by the rice milling rolls 24. At this time, the degree of rice milling is adjusted by adjusting the elasticity of the spring 22 to be strong or weak. If the elasticity of the spring 22 is made strong, the polishing tube 25
does not rotate in the opposite direction A even if a considerable load is applied to it.If the elasticity of the spring 22 is weak, the polishing cylinder 25 will begin to rotate even with a small load, and the volume of the rice polishing chamber 26 will be reduced. By increasing the size and softening the load,
In the end, it is extremely important to be able to finely adjust the elasticity of the spring 22, but in this invention, when the manual rotation knob 28 is rotated, the ohm 21 rotates, and the ohm 21 rotates the gear 19. The movement in the A direction can be carried out very delicately, and after adjustment, the ohm 21 acts to prevent reverse rotation, thereby preventing the gear 19 from naturally reversing.
