Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a whiteness display device in a rice milling machine.

(Prior art) Fig. 1 shows a known example, in which a is a supply port, b is a grain feeding chamber, and c is a rice milling chamber.The outer periphery of the grain feeding chamber b is surrounded by a fixed grain feeding cylinder d, and the rice milling chamber c The outer periphery of is surrounded by a grain barrel e. f is a grain feeding spiral, g is a rice milling roll, and h is a discharge port. When rice is milled in the rice milling chamber c, the grain milling cylinder e rotates as shown by arrow A in accordance with the load. The spring i prevents this rotation, and the grain polishing tube e is suspended via the diagonal rod j, so when the grain polishing tube e rotates against the elasticity of the spring i,
The diagonal rod j is vertically displaced, and the grain mill e is moved downward to open the discharge port h. The strength of the spring i is adjusted by the position of a rotating body k, the position of which is adjusted by a motor, and its position is readable with a pointer m. n is a scale plate.

(Problems to be solved by the invention) In the above-mentioned known device, the pointer m is directly attached to the rotating body k, so when the pointer m moves to the end of the scale plate n, it is difficult to read and the adjustment may be incorrect. Something happened.

This is because the pointer m is fixed to the rotating body k and moves in an arc, and the present invention improves this point to make it easier to see.

(Means for solving the problem) The present invention, which has been devised thus far, has a feeding tube 2 provided in the center of the frame 1, a vertical fixed grain feeding tube 8 provided at the bottom of the feeding tube 2, and a fixed vertical grain feeding tube 8. There is a rice polishing cylinder 9 at the bottom of the
A rotating body 13 that rotates horizontally is provided on the upper outer periphery of the vertical fixed grain feeding cylinder 8, and a spring 15 is provided between the rotating body 13 and the rice polishing cylinder 9. A diagonal rod 16 is provided between the rice polishing cylinder 9 and the rice polishing cylinder 9 rotates against the spring elasticity according to the rice polishing load and moves downward by the action of the diagonal rod 16. , a semi-arc-shaped whiteness scale body 19 is provided on the rotating body 13, and the whiteness scale body 19 faces a window 20 provided in the frame 1, and a cursor 21 is provided in the window 20. It has the configuration of a degree display device.

(Example) An example of the present invention will be described with reference to the drawings.
is the entire frame, a supply tube 2 is provided at the upper center of the frame 1, and a valve 3 and a flow rate control valve 4 are provided on the supply tube 2. The flow control valve 4 is connected to the drive shaft 5
When rotated, it opens and closes due to the transmission of gears 6 and 7.

A vertical fixed grain feeding tube 8 is provided at the bottom of the feeding tube 2. A rice polishing cylinder 9 is provided at the bottom of the vertically fixed grain feeding cylinder 8, and an upper member 10 is fitted into the upper part of the rice polishing cylinder 9 so as to be rotatable and vertically movable. At the bottom of the rice polishing cylinder 9, there is a lower member 1 that moves up and down together with the rice polishing cylinder 9.
1 is provided. A discharge port member 12 is provided inside the lower member 11, and when the lower member 11 moves downward, a gap between the discharge port member 12 and the discharge port member 12 is increased. A rotating body 13 is provided on the upper outer periphery of the vertically fixed grain feeding cylinder 8,
It is rotated by a motor 14. A spring 15 is provided between the rotating body 13 and the upper member 10, and a diagonal rod 16 is provided between the vertically fixed grain feeding cylinder 8 and the upper member 10. 17 is a screw, and 18 is a rice mill roll.

Thus, the rotating body 13 is provided with a semi-arc shaped whiteness scale body 19. The whiteness scale body 19 is like an inverted plate-shaped body divided into three parts, and has scales attached to its outer peripheral surface, and is attached to the lower side of the rotating body 13 with screws or the like. The whiteness scale body 19 is provided facing the inside of a window 20 formed in the frame 1, and a cursor 21 is provided in the window 20.

(effect) Next, we will discuss the effect.

When the valve 3 is opened, the grains in the supply cylinder 2 flow down into the vertical fixed grain feeding cylinder 8, are sent downward by the screw 17, and are polished by the rice milling rolls 18.

When the rice milling load increases due to the rice milling roll 18,
The rice polishing cylinder 9 rotates in the direction A due to the load, and therefore the upper member 10, which is integrally constructed with the rice polishing cylinder 9, similarly rotates in the direction A. This rotation is performed against the elasticity of the spring 15, thereby displacing the oblique rod 16, which was initially oblique, to an upright state.
The upper member 10 is moved downward in the direction B, and the lower member 11 is also moved downward in the direction B via the rice polishing cylinder 9.
1 and the discharge port member 12 is adjusted. The rotation of the rice polishing cylinder 9 in the A direction is adjusted by the elasticity of the spring 15, and the elasticity of the spring 15 is controlled by rotating the rotating body 13 by the motor 14.

When the rotating body 13 rotates, the whiteness scale body 19 rotates integrally, so that the spring 15 is moved from the part where the scale of the whiteness scale body 19 and the cursor 21 match.
You can know the elasticity of

(Effects) Figure 1 shows a known example, where a is a supply port, b is a grain feeding chamber, and c is a rice milling chamber. The outer periphery is surrounded by a grain barrel e. f is a grain feeding spiral, g is a rice milling roll, and h is a discharge port. When rice is milled in the rice milling chamber c, the grain milling cylinder e rotates as shown by arrow A in accordance with the load. The spring i prevents this rotation, and the grain polishing tube e is suspended via the diagonal rod j, so when the grain polishing tube e rotates against the elasticity of the spring i,
The diagonal rod j is vertically displaced, and the grain mill e is moved downward to open the discharge port h. The strength of the spring i is adjusted by the position of a rotating body k, the position of which is adjusted by a motor, and its position is readable with a pointer m. n is a scale plate.

In the above-mentioned known device, the pointer m is directly attached to the rotating body k, so when the pointer m moves to the end of the scale plate n, it is difficult to read and adjustments may be made incorrectly.
