Description

The present invention relates to a chestnut processor suitable for use in the work of making cuts in chestnuts.

When peeling chestnuts or cooking roasted chestnuts, it is necessary to make a cut in the devil's skin on the surface of the chestnuts. Conventionally, this work is performed by holding a chestnut in one hand and using scissors or a knife. Work with scissors and knives requires skill until it can be cut as a single straight line. In addition, an accident in which an operator accidentally injures a finger or the like is likely to occur.

In order to prevent such an accident, for example, Patent Document 1 describes a boiled chestnut splitter provided with a cutting edge instead of one of the intersecting blades in conventional scissors and a chestnut receiving portion instead of the other. ing.

<Structure example of chestnut processing machine 10 according to one embodiment of the present invention>
First, a configuration example of the chestnut processing machine 10 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a perspective view showing a configuration example of the chestnut processing machine 10. FIG. 2 is a side view showing a configuration example of the chestnut processing machine 10. FIG. 3 is a front view showing a configuration example of the pedestal portion 30. 4A and 4B are views showing a configuration example of the cutter portion 20, FIG. 4A is a front view, FIG. 4B is a back view, and FIG. 4C is a side view seen from the front left side. (D) is a side view seen from the front right side.

The chestnut processing machine 10 includes a cutter portion 20 and a pedestal portion 30.

The cutter portion 20 is gripped by an operator and moved laterally while being pressed against the pedestal portion 30 to rotate the chestnut 50 (FIG. 6) placed on the pedestal portion 30 around the devil's skin. It makes a notch.

The cutter portion 20 has a linear blade 22 at substantially the center in the thickness direction of the bottom portion of a substantially trapezoidal shape (in this embodiment, a pentagon in which the upper right apex of the rectangle is cut off). In the cutter portion 20, a substantially trapezoidal front plate 21A and a back plate 21B are in close contact with each other by, for example, screws, and the blade 22 is formed by sandwiching the back side of the blade 22 between the front plate 21A and the back plate 21B at the bottom thereof. Is fixed.

For the front plate 21A and the back plate 21B, a material having a predetermined strength such as wood is used.

The blade 22 has a substantially rectangular shape, and its tip is formed at an acute angle. As a result, the blade 22 can be pierced into the chestnut 50. Therefore, the initial position of the cut with respect to the chestnut 50 can be reliably determined. As the blade 22, a commercially available parallelogram cutter blade can be used.

For example, a low friction material 23 made of fluororesin is provided on the back surface of the cutter portion 20, that is, the surface of the back surface plate 21B that is not bonded to the front plate 21A. As a result, the cutter portion 20 can be smoothly moved while being pressed against the pedestal portion 30.

The cutter portion 20 can be disassembled by removing the screws that bring the front plate 21A and the back plate 21B into close contact with each other, so that the blade 22 and the low friction material 23 can be easily replaced.

The cutter portion 20 shown in the figure assumes a work in which a right-handed worker grips an inclined portion with his right hand and moves it to the left. If the left-handed worker is left-handed, the left-handed one, that is, the cutter portion 20 having a substantially trapezoidal inclined portion provided on the left side and the tip on the right side of the blade 22 having an acute angle is prepared, and the cutter portion 20 is turned to the right. You just have to move it in the direction.

The pedestal portion 30 is for placing the chestnut 50 on it, and is mainly formed of a material having a predetermined strength such as wood.

The pedestal portion 30 has a first plane 31 on which an elastic material 33 such as urethane rubber having a predetermined hardness and flexibility is laid, and a second plane 32 connected to the first plane 31 at a substantially right angle. .. The elastic material 33 is adhered to the first plane 31 with a gap g having a predetermined width with respect to the second plane 32. However, the gap g is not essential, and the elastic material 33 may be in contact with the second plane 32.

Further, the pedestal portion 30 includes a fixing member 34 for fixing the first plane 31 and the second plane 32 connected at substantially right angles to the mounting member 35 at a predetermined angle α (for example, 45 °), and a work desk. It has a mounting member 35 for mounting the pedestal portion 30 on (not shown) or the like.

By fixing the first plane 31 and the second plane 32 connected at substantially right angles to the mounting member 35 at a predetermined angle α, the posture of the placed chestnut 50 can be stabilized.

<Example of placing chestnut 50>
Next, FIG. 5 is a side view showing a state in which the chestnut 50 is placed on the pedestal portion 30.

The chestnut 50 is placed on the elastic material 33 with its flat side surface facing the second plane 32. The figure shows a state in which the bottom of the chestnut 50 is visible. By placing the chestnut 50 on the elastic material 33 having a predetermined hardness, it is possible to prevent the chestnut 50 from slipping when the cutter portion 20 is pressed against the chestnut 50 and moved laterally. Further, since the chestnut 50 is embedded in the elastic material 33, the chestnut 50 can be easily rotated regardless of the difference in shape. Further, since the gap g is provided between the second flat surface 32 and the elastic material 33, when the chestnut 50 is pressed against the pedestal portion 30 by the cutter portion 20, the elastic material 33 is recessed on the gap g side and the chestnut 50 is formed. Since the stress of the chestnut 50 is dispersed by slightly digging in, the posture of the chestnut 50 can be more stably rotated. Further, when the cutter portion 20 is pressed against the second plane 32 and moved in the lateral direction, the height of the blade 22 (distance from the second plane 32) becomes constant, so that the entire circumference of the rotated chestnut 50 is reached. On the other hand, a straight notch can be made.

<How to use chestnut processor 10>
Next, FIG. 6 is a diagram for explaining how to use the chestnut processing device 10.

First, as shown in the upper right corner of the figure, an operator places the chestnut 50 on the elastic material 33 with the flat side surface of the chestnut 50 facing the second plane 32 and the tip end facing the left side. Then, the operator pierces the chestnut 50 with the tip of the blade 22 in a state where the low friction material 23 of the cutter portion 20 is in contact with the second flat surface 32.

Next, as shown in the upper left, middle, and lower stages of the figure, the operator brings the low friction material 23 into contact with the second plane 32 with the blade 22 stuck in the chestnut 50, and the chestnut 50 is pressed. The cutter portion 20 is moved to the left while being pressed toward the first flat surface 31 side. As a result, the chestnut 50 rotates counterclockwise, and a straight notch is made all around the demon skin. The cut chestnut 50 falls into a box (or bag) 51 arranged next to the pedestal portion 30.

The chestnut processor 10 can be used not only when making a cut on the entire circumference of the chestnut 50 but also when making a cut in a part around the chestnut 50.

<Summary>
According to the chestnut processor 10 of the present embodiment, the chestnut 50 placed on the pedestal portion 30 is simply pierced with the tip of the blade 22 and the cutter portion 20 is moved to the left once, and the chestnut skin of the chestnut 50 is peeled. A straight notch can be made around the entire circumference of the. Therefore, the work of making a cut in the demon skin of the chestnut 50 can be efficiently performed.

Further, according to the chestnut processor 10, the work can be safely performed without holding the chestnut 50 in the hand.

Further, according to the chestnut processing machine 10, a commercially available cutter blade can be used as the blade 22 of the cutter unit 20, so that the operating cost of the chestnut processing machine 10 can be suppressed.
