DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a millstone device,
In particular, the present invention relates to a stone mill device capable of smoothly supplying grain to a sliding surface between a lower mill and an upper mill without clogging a hopper.

[0002]

2. Description of the Related Art In a millstone apparatus, an upper mill is rotated and driven by a driving body such as a motor, and supplies grains such as buckwheat, wheat and soybeans to a millstone from a supply hole formed in the upper mill, and the lower mill and the upper mill. This is a device that grinds and grinds on the surface in contact with the mortar. The grain is
Usually, the powder is milled into a fine powder having a fine mesh, but depending on the use of the powder, a powder having a coarse mesh may be required. In order to mill the grains into coarse-meshed powder, it is sufficient to increase the amount of grain supplied to the mill, so that a large amount of grain enters the sliding surface between the lower mill and the upper mill, and the upper mill is This is because sufficient crushing cannot be performed because of the floating. On the other hand, in order to mill the grains into fine powder having a fine mesh, the amount of grains supplied to the millstone may be reduced.

[0003] As described above, in the millstone apparatus, it may be necessary to adjust the mesh of the powder to be milled, so that means for adjusting the supply amount of the grain is provided. Various types of grain supply adjustment means have conventionally been provided,
The means for adjusting the supply amount of grain in the millstone device 200 shown in FIGS. 3 and 4 can easily adjust the supply amount, and is optimal for reducing the size and cost of the device. The supply of grain to the millstones 180 and 190 in the device 200 is performed by the first hopper 130 and the second hopper 140. The first hopper 130 has a supply amount adjusting pipe 134 attached to a drop port 132 below the funnel body 131. Further, the second hopper 140 is provided upright on the upper mill 180, and is provided with a supply amount adjustment tray 144 supported by the funnel 141. Supply amount adjustment pipe 134 and supply amount adjustment pan 144
Are arranged to face up and down, and the supply amount adjusting pipe 13
A gap 17 is provided between the lower end edge of
The gap width W3 of the gap 170 can be arbitrarily increased or decreased since the supply amount adjusting pipe 134 can move up and down along the drop port 132. Then, the cereal thrown into the first hopper 130 falls from the drop port 132 onto the supply amount adjustment tray 144, and the cereal is stored in the gap 170. The second hopper 140 is the upper mill 18
0, it rotates together with the upper mill 180, and the supply amount adjustment tray 144 supported by the funnel 141 of the second hopper 140 also rotates, so that the grains accumulated in the gap 170 are supplied by centrifugal force. It falls into the funnel body 141 of the second hopper 140 from the amount adjustment tray 144, and is further supplied into the supply hole 181 of the upper mill 180. Therefore,
The supply amount of the grain to the millstones 180 and 190 depends on the gap width W3. The gap width W3 is adjusted because the supply amount of the grain increases when the gap width W3 is large and decreases when the gap width W3 is small. By doing so, the supply amount of grain to the stone mills 180 and 190 can be adjusted.

[0004]

However, in the means for adjusting the amount of grain supply shown in FIGS.
Grains supplied to 0 and 190 are irregular in grain size, such as buckwheat-like grains in which the grain size varies depending on the cultivar and the place of production as well as the varieties and the place of production. Into the first hopper 130, the grains fall
32. That is, the gap width W3 between the lower end edge of the supply amount adjustment pipe 134 and the supply amount adjustment tray 144
Is usually adjusted to a width smaller than the particle diameter of the maximum diameter of the grains to be put into the first hopper 130, so that the grain having a particle diameter larger than the gap width W3 has It was blocked by the inner wall at the lower end and could not fall into the funnel 141 of the second hopper 140, and gradually accumulated along the inner wall at the lower end of the supply amount adjusting pipe 134, and was further blocked by grains having this large particle size. Grains having a small particle size cannot be dropped, and eventually the grains are clogged in the falling port 132. When the grain is clogged in the falling port 132 in this manner, (1) the worker moves the supply amount adjustment pipe 134 upward to move the lower end edge of the supply amount adjustment pipe 134 and the supply amount adjustment tray 144.
In such a case, it is necessary to increase the gap width W3 between the first and second mills, and to drop the clogged grain. Also, by widening the gap width W3 and dropping the cereal clogged in the falling port 132 at a time, a large amount of cereal can be milled.
0, 190, and the powder mesh becomes coarse,
The milled powder has a disadvantage that fine and coarse meshes are mixed and non-uniform. (2) Since the milling operation does not proceed smoothly, much time was required until the operation was completed. (3) Since no grain is supplied to the sliding surface between the lower mill 190 and the upper mill 180, the stone mills 180, 190 are in an empty state, and the eyes of the stone mills 180, 190 may be crushed, so that sharpening is required and accordingly Wasted expense. There was a problem.

Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a stone mill device capable of smoothly supplying grains having irregular particle diameters to a mill without clogging in a hopper.

[0006]

Means for Solving the Problems The present inventor has conceived of the present invention by diligently pursuing the cause of grain clogging in a hopper, and the invention according to claim 1 comprises a lower mill and a driving body. The supply of the grain to the sliding contact surface with the upper mill driven by the rotation is performed by a first method in which the grain is supplied above the upper mill and the worker inputs the grain.
A hopper and a second hopper that stands on the upper mill and that supplies the grains falling from the first hopper into a supply hole formed in the upper mill are performed by the hopper. A lower end edge of a supply amount adjusting pipe attached to a dropping port below the funnel body of the first hopper and movable up and down along the dropping port; and a lower end edge of the supply amount adjusting pipe supported by the funnel body of the second hopper. A stone mill device that is provided by a gap width between a supply amount adjustment tray disposed at a lower facing position and prevents a grain from being clogged in a dropping port of the first hopper at a lower edge of the supply amount adjustment tube. A stone milling device characterized in that clogging preventing means is provided.

According to the invention having the above structure, even if the grain stored in the gap between the lower end edge of the supply amount adjustment pipe and the supply amount adjustment tray is a grain having a large particle size, the grain is easily dropped into the funnel body of the second hopper. Thus, the amount of grain supplied to the millstone can be freely adjusted without clogging the grain at the dropping port of the first hopper.

A second aspect of the present invention is the stone milling apparatus according to the first aspect, wherein the supply amount adjusting pipe is detachably attached to a drop port of the first hopper.

According to the invention having the above-described structure, if a supply amount adjusting tube having clogging prevention means corresponding to grains having various particle sizes is prepared, various particle sizes can be obtained simply by replacing the supply amount adjusting tube. It is possible to cope with the milling of various cereals.

, And communicates with the inside of the drop port 42, and the other end is inserted into a supply hole 81 formed in the upper mill 80.

Next, a method of supplying grains to the millstones 80 and 90 by the first hopper 30 and the second hopper 40 configured as described above will be described with reference to an example of milling buckwheat. First, the gap width W1 of the gap 70 between the lower end edge of the supply amount adjustment pipe 34 and the supply amount adjustment tray 44 is adjusted so that a desired amount of buckwheat can be supplied to the millstones 80 and 90. Even if the buckwheat is of the same origin and varieties, the grain size is about 3 mm to about 5 mm, and if the gap width W1 is set to be almost the same as the grain size of the largest buckwheat, a large amount of buckwheat will be milled. , And only buckwheat flour having a very coarse mesh can be obtained. Therefore, the width must be set smaller than this. The gap width W1 is adjusted by the supply amount adjusting pipe 34.
Is moved to a predetermined position while rotating the operation rod 37 (the lower end edge of the supply amount adjusting pipe 34 is located below the lower end edge of the drop port 32). The fixed pipe 36 is moved until the lower end of the fixed pipe 36 abuts on the upper end of the adjusting pipe 34, and then the supply amount adjusting pipe 34 and the operating rods 37 and 38 of the fixed pipe 36 are tightened by turning them in opposite directions to each other. Numeral 34 is fixed at a predetermined position and does not move up and down. When the gap width W1 can be adjusted, a predetermined amount of buckwheat to be milled is put into the first hopper 30. A part of the thrown buckwheat is supplied from the drop port 32 of the first hopper 30 to the supply amount adjustment tray 44.
It falls down and is stored in the gap 70. Therefore, when the power of the motor 60 is turned on, the supply amount adjustment tray 44 is turned on.
Is supported by the funnel 41 of the second hopper 40, and rotates with the rotation of the upper mill 80. The buckwheat accumulated in the gap 70 falls into the funnel 41 of the second hopper 40 by centrifugal force, and is further supplied. It is supplied from the pipe 45 to the sliding surfaces of the stone mills 80 and 90. Then, as the buckwheat falls from the gap 70 into the funnel body 41 of the second hopper 40, the buckwheat successively falls from the drop outlet 32 of the first hopper 30 onto the supply amount adjusting plate 44. A desired amount of buckwheat adjusted by the gap width W1 can be continuously supplied to the millstones 80 and 90.

As shown in FIG. 2, a notch 35 having a size such that even a buckwheat having the largest diameter can fall into the funnel 41 of the second hopper 40 is formed at the lower end edge of the supply amount adjusting tube 34.
In other words, the notch 35 is formed such that the gap width W2 between the upper end of the notch 35 and the supply amount adjusting tray 44 is slightly larger than the particle diameter of the maximum diameter buckwheat. Therefore, even if the upper part of the buckwheat having a large particle diameter is blocked by the inner wall at the lower end of the supply amount adjusting pipe 34, the supply amount adjustment pan 44 is rotating, and the buckwheat having the large particle diameter is supplied with the rotation. When the notch 35 of the adjusting tube 34 is reached, the notch 35 can be easily passed through. Therefore, the buckwheat having a large particle diameter also falls into the funnel body 41 of the second hopper 40 due to the centrifugal force, and the buckwheat of a desired amount is smoothly crushed into the stone mill 80 without the buckwheat clogging the falling port 32 of the first hopper 30. 90. It should be noted that only one notch 35 may be formed at the lower end edge of the supply amount adjusting pipe 34, but if the amount of grain having a large particle size increases, it is preferable to form two notches 35 facing each other. More preferably, as in the present embodiment, it is more preferable to form four notches 35 that face each other. In addition, since the supply amount adjusting tube 34 is detachable from the drop port 32 of the first hopper 30, the cutout 35 can be replaced with a different supply amount adjusting tube 34 for milling various grains having various particle sizes. Can correspond.

The stone mill according to this embodiment in which the gap width W1 between the lower end edge of the supply amount adjustment tube 34 and the supply amount adjustment tray 44 is the same, and the cutout 35 is provided at the lower end edge of the supply amount adjustment tube 34. When milling buckwheat of the same production area and varieties of 5 kg each with the device 100 and the stone mill device without the notch 35, the millstone device 100 according to the present embodiment,
Although milling could be performed without clogging the falling port 32 of the first hopper 30 once, the buckwheat was clogged approximately every 10 minutes in the milling machine without the notch 35.

The present invention can be embodied by changing various aspects, and is exemplified below. (1) The clogging prevention means provided at the lower edge of the supply amount adjusting pipe 34 may be performed by forming the lower edge in a wavy shape. (2) The rotation of the upper mill 80 by the motor 60 may be performed by any method, and may be performed via a gear or directly by the rotation shaft of the motor 60. (3) The support 51 supporting the first hopper 30 is
It may be configured to be erected at 0.

[0018]

Since the present invention is configured as described above in detail, it has the following effects.

According to the first aspect of the present invention, since the lower end edge of the supply amount adjusting pipe of the first hopper is provided with a means for preventing clogging, the first hopper falls even if the grain size of the milled grains varies. It can be milled without cereal clogging.
Therefore, no manpower is required during the milling operation, and the operation can be completed in a short time. Furthermore, it can be milled into a uniform mesh powder. In addition, since the grains are not clogged in the first hopper, the millstone is not emptied, sharpening is unnecessary, and the maintenance cost of the millstone device can be reduced.

According to a second aspect of the present invention, in addition to the effect of the first aspect, since the supply amount adjusting tube is detachable from the dropping port, the supply amount is provided with clogging prevention means for various particle sizes. By replacing the control tube, milling of various grains having various particle sizes is possible.
