Abstract

<P>PROBLEM TO BE SOLVED: To enable a tassel plucking device, having two rollers formed of elastomers, disposed in right and left parallel and made to self-rotate oppositely and intrudingly to each other, to continuously and automatically pluck the tassel. <P>SOLUTION: One roller is formed of the elastomer harder than that of the other roller. The harder roller is made to self-rotate slightly faster than the softer roller. The rollers each keep one end elevated to tilt an intruding part. A water spray device is disposed above the rollers. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

The present invention relates to a corn treatment apparatus in which two rollers made of an elastic body are arranged in parallel in the left-right direction and rotate in the biting direction, and is used when corn hair is automatically removed.

As an apparatus for peeling corn, the apparatus disclosed in Patent Document 1 is known, but there is no known technique relating to an apparatus for automatically removing corn hair.
The above-mentioned skinning device is formed of an elastic body such as rubber, and a plurality of rollers having spiral grooves on the surface are arranged in a bowl shape, and the spiral direction and the rotation direction of adjacent grooves are reversed. In this device, the roller surfaces are engaged with each other, and the harvested corn is fed onto the roller, and the skin and stems are removed from the ear by sandwiching the skin between the rollers.

However, the above apparatus can remove hard skin and stems by meshing with rollers, but cannot remove fine hairs that grow concentrated on the tip.
When processing corn into feed, it is not necessary to completely remove hair, but when using it as food, removal of hair is an essential process.
Although the corn tips are faced one by one between the rollers arranged in parallel in the left and right direction and rotated in the biting direction, the hair is also removed manually, but the hair cannot be removed neatly, In addition, the hair that has been removed winds around the roller, and the hair cannot be removed continuously.
US Pat. No. 5,451,184

An object of the present invention is to enable continuous and automatic removal of corn hair in a corn treatment apparatus in which two rollers made of an elastic body are arranged in parallel in the left-right direction and rotate in the biting direction. It is what.

The first technical means for solving this technical problem is: (b) one of the rollers is formed of an elastic body harder than the other, (b) the hard roller is rotated slightly faster than the soft roller, and (c) One end side of the roller is raised to incline the biting portion, and (d) a watering device is disposed above the roller.
The second technical means is that the soft roller is formed of a soft foam, and the third technical means is that a watering device is disposed below the roller.

In the first technical means, the roller is composed of a hard roller and a soft roller, and the former hard roller is rotated slightly faster than the latter soft roller. A rotational force is applied by the hard roller, and the roller is rotated between the rollers.
At this time, since the corn is rotated in the same direction as the soft roller, the corn hair is wound around the corn in the direction opposite to the rotation direction of the corn. The soft roller removes the hair by rubbing it from the root side by applying a frictional force, and the hair is bitten between the hard roller.

Since one end of the roller is raised and the biting portion of the roller is inclined, the corn fed between the rollers moves while rotating and moves downward between the rollers. The hair that is densely gathered at the tip is automatically removed.
Since the watering device is arranged above the rollers, the supplied corn is always wet and is smoothly moved on the rollers, and the removed hair flows out under the rollers together with the water, The removed hair does not wind around the roller, and the hair is removed continuously.

As the elastic body constituting the surface of the roller, synthetic rubber or synthetic resin can be suitably used.
In addition, if the soft roller is formed of a soft foam, the frictional force against corn can be increased, so that the hair can be removed more efficiently.
If a watering device is also arranged below the roller, water is supplied from the lower side to the hair that the roller bites into and discharges, so that it flows out more smoothly.

As a result of the continuous and automatic removal of corn hair, there is an advantage that the corn can be processed smoothly and efficiently.

FIG. 1 is a front view of a corn hair removing apparatus 1 according to the present invention.
The apparatus 1 supports rollers 11 and 12 (see FIG. 2) arranged in a horizontal direction in the machine casing 2 in an oblique direction.
In this embodiment, the surface is composed of a roller 11 made of synthetic rubber having a hardness of 70 ° and a roller 12 made of soft foam rubber having a hardness of 45 °. In these rollers, the rotational force of the motor 3 is transmitted through the gear mechanism 4, and the former is 150 rpm. The latter is 110 rpm. Is rotating in the direction of the arrow at a speed of.

On the upper end side of the rollers 11 and 12, an endless belt 6 driven by a motor 5 is disposed outside the machine frame 2 and travels in the arrow direction. When the corn 10 from which the skin has been removed is placed on this, the corn 10 is automatically supplied onto the rollers 11 and 12.

The corn 10 supplied on the rollers 11 and 12 moves to the lower end side of the rollers while being rotated by the rollers 11. A sprinkler 7 is disposed above the rollers 11 and 12, and the corn 10 is rotated and moved in a wet state.

The roller 12 removes this by applying a frictional force from the root side of the hair wound in the direction opposite to the direction of rotation of the corn, and discharges it together with water to the lower side of the roller. A sprinkler 8 is also arranged below the stub to ensure that the removed hair flows out.

The hardness of the rollers 11 and 12 and the difference in hardness are not limited to the above-mentioned hardness. The design will take into account the length of the roller, the installation angle, and the size of the corn.
