JPS596770Y2 - Seed potato cutting knife - Google Patents

Description

[Detailed explanation of the invention] When using a commercially available cooking knife to cut a part of the seed potato and make a slit (hereinafter referred to as the slit work), if the seed potato is cut into two pieces, everyone can cut the seed potato into two pieces. I was able to easily make cuts with a few movements.

(See Figure 4) However, when making three cuts in a large seed potato, it was necessary to make two cuts both vertically and horizontally, which was time-consuming.

Moreover, as with cutting in two, it is necessary to leave a moderate amount of uncut material, so a certain degree of skill is required, and if one does not concentrate one's attention, one may accidentally cut the part completely.

(See FIG. 5) This invention eliminates the above-mentioned drawbacks by simple means and enables even unskilled workers to easily and accurately cut into seed potatoes.

To explain the kitchen knife of this invention based on the drawing, the cutting blade A has a cutting edge 1 with a concave central part, and the cutting blade B has a cutting edge 2 with a step-like end part. This knife is characterized by being assembled and fixed to the mold at different levels.

Using this kitchen knife, (1) Cutting the seed potato into three pieces can be done in one operation (cutting into two pieces is done using only the cutting blade B) (2) The center part of the cutting blade A is concave, and the cutting blade Since the end of B is shaped like a step and these two blades are combined in different steps, even an unskilled person can reliably create a uniform uncut area and perform the cutting operation.

Effects such as this can be obtained.

*Regarding uncut portions of seed potatoes Seed potatoes are sown using each cut as seeds, but the seed potatoes that have been cut immediately after cutting still retain their original shape because they still have uncut portions.

Seed potatoes are sown using a potato planter, and at that time, a worker sitting on this machine breaks the uncut seed potatoes one by one, checking for diseases or other abnormalities, and They are always placed next to each other and fed into the seeding machine.

If the cut surface is exposed before sowing, if there are any sick potatoes, the infection will spread to other potatoes.

In addition, if a diseased plant is found during removal of abnormal plants (diseased or otherwise) after germination, all the potatoes that have sprouted from one seed potato are at risk of developing the disease (or have already developed the disease). All strains before and after the diseased strain (2 to 3 strains)
It extracts the.

Therefore, unless the above-mentioned sowing method is used, it will be difficult to extract the seeds.

For the reasons mentioned above, leaving seed potatoes uncut is now indispensable.
