Description

[Detailed explanation of the invention] When a tightly wound coil spring is twisted around its axis and a daikon radish with a beard is brought into contact with it by hand,
A phenomenon occurs in which thread-like substances such as hair roots are caught between adjacent coil pieces of the coil spring, and the thread-like substances are cut and removed.

This idea takes advantage of the characteristics of coil springs,
This invention relates to a machine that efficiently removes the roots of radish and other root vegetables.

Root vegetables such as daikon radish and burdock have a large number of hair roots, which vary slightly depending on the variety, soil quality, etc., and even if they are washed with brushes and water using a washing machine, most of the hair roots cannot be removed, and they are later removed manually. That was the reality.

For this reason, there was a desire for a simple mechanical removal method, but
The present invention exactly meets these demands.

In the figures, the device shown in FIGS. 1 and 2 is an example of a device in which the present invention is implemented using two coil springs. 2
Two coil springs 2 and 3 are supported substantially parallel to each other.

Each coil spring 2, 3 is tightly wound, a collar 21.31 is fixed to one end, an interlocking gear 22.32 for mutual interlocking is attached, and one collar 21 is extended to provide a passive Install sprocket 23.

The other ends of both coil springs 2 and 3 are rotatably supported by a bearing 17 near the other end of the frame 1, and are used as free ends.

12 is a frame base, 13, 13 are side frames, 14 is a front crosspiece including the front bearing part 15, and 16 is the rear bearing part 1.
This is the rear crosspiece including 7.

A first motor M1 with a reduction gear is supported below the frame, and twists and drives the passive sprocket 23 in a fixed direction via the drive sprocket 4.

41 is the interlocking chino. This twist (color 21
rotation around the axis) is transmitted to the coil spring 3 via the interlocking gear 22° 32, causing the coil spring 3 to twist in the opposite direction to the coil spring 2.

As described above, the two coil springs 2 and 3 are supported almost parallel to each other by the front bearing part 15 and the rear bearing part 17, and the distance between them is determined by the whiskers of the object to be treated, for example, the thick root W (Fig. 1). Make it smaller than the normal diameter of the part with roots.

The direction in which the coil spring is twisted by the coil spring drive device is
It is best to wind up the workpiece from above as shown by the arrow in Figure 2.If a radish W, etc. is inserted between both coil springs 2. When the coil spring opens on both sides and twists in the direction of the arrow as shown in the figure, each coil piece will sandwich the hair roots between the coils on the outside of the curved area where the distance between each coil piece is widened, and the inside of the curved area. Now cut off the pinched hair roots.

Then, when the hair turns outward next time, the cut hair roots are separated from between the coils.

Since the coil springs 2 and 3 are continuously twisted, the roots of root vegetables can be completely removed by reciprocating between the coil springs several times.

Next, the apparatus shown in FIGS. 3 to 5 will be explained.

In this embodiment, a shaft 51, such as a metal rod or pipe, is attached to both ends.
52 is assembled into a V-shape or U-shape (as shown in the figure) in the middle of the coil spring portion,
It is supported almost horizontally on the upper surface of the frame 1.

Frame 1 consisting of base 11, 12 and side frames 13 as before
has two sets of parallel bearings 19, 19 near one end of its upper surface.
A coil spring bent into a V-shape or U-shape, with the shafts 51 and 52 at both ends of the coil spring supported almost horizontally and rotatably around the shaft. 50 is maintained substantially horizontally on the top surface of the frame.

Further, a passive sprocket 53 is attached to one of the shafts assembled to the coil spring 5, for example 51, and is interlocked via a chino 61 with a drive sprocket 6 of a second motor M2 with a reduction gear supported by the frame.

When the second motor M2 is operated to rotate the shaft 51 in the direction of the arrow in FIG.
is also rotated as shown by the arrow in FIG. 3, causing the same movement of the coil spring as previously described at the bent portion 50 of the coil spring.

If you press a root vegetable with hair roots growing inside this curved part and move it up and down several times in the axial direction while rotating it around the axis as appropriate, you can see the hair roots growing around the root vegetable. is completely excised from the base.

The details of the action of the coil spring will be explained with reference to FIG. 6. At the bent portion 50 of the coil spring, each coil piece 54 comes into close contact with each other on the inside of the coil, while on the outside of the coil, each coil piece 54 comes into close contact with each other. A gap 55°55 is continuously formed between them.

The portion that is in close contact with the portion where the gap is created sequentially moves from the outside to the inside of the coil as the coil spring is twisted.

Therefore, as described above, the beard roots are pinched and cut, and then released and separated.

Figures 7a and b show the work of cutting off the roots of a radish using the above-mentioned device.The roots 7 of the radish are cut out along the 18,000 line around the radish W, as shown in Figure 8. It grows in two rows (usually somewhat twisted in length).

Therefore, by repeating the process twice of placing the hair root in the center of the coiled spring curved part 50 and moving it in the axial direction (usually from top to bottom as shown in Fig. 7), the hair root of one radish can be completely removed. It is removed.

The device of the present invention described above greatly streamlines the process of removing the roots of root vegetables, which conventionally required a long time, and greatly contributes to the streamlining of farm work.
