  However, the conventional walnut cracker has the following problems to be solved. That is, when a walnut is cracked using a conventional walnut cracker, it is necessary to fit the protruding edge portion of the walnut into the fitting locking groove of the holding recess provided at the tip of the holding rod. However, it is not easy to maintain the balance of the walnuts with the protruding edges fitted in the fitting locking grooves, so the walnuts will fall from the holding recesses and efficiently perform the walnut splitting work There is a problem that it is not. In addition, in the conventional walnut splitting device, when the walnuts are sandwiched between the sandwiching recess and the walnut splitting blade and the shell is split, a part of the shell is crushed and scattered. Will be.

  This invention is made | formed in view of this subject, and it aims at providing the walnut splitter which can perform the operation | work which cracks a walnut shell easily, preventing scattering of a shell.

  In order to achieve the above object, the walnut splitter according to claim 1 is a walnut splitter for splitting a walnut shell and taking out seeds, and comprising a rectangular bottom plate and side plates erected on each edge of the bottom plate A pair of casings configured to accommodate the walnuts and a pressing portion for pressing the walnuts stored in the casing and breaking the shell, One of the side plates is provided with a support portion having a screw hole, and the pressing portion is supported by the support portion while being screwed into the screw hole of the support portion and a distal end portion is located in the housing. A screw rod, an abutting portion attached to the tip portion so as to be rotatable relative to the tip portion, and a knob attached to a base end portion of the screw rod. The walnuts between the other of the pair of side plates in the body and the contact portion The contact portion is configured to press the walnuts by in the contained state by rotating the knob screwed the threaded rod.

  Moreover, the walnut splitter of Claim 2 is a walnut splitter of Claim 1, Comprising: The recessed part is provided in the center part of the said contact part.

  Moreover, the walnut splitter of Claim 3 is a walnut splitter of Claim 1 or 2, Comprising: The recessed part is provided in the inner surface of said other side plate.

  A walnut splitter according to claim 4 is the walnut splitter according to any one of claims 1 to 3, wherein the knob is formed in a cylindrical shape.

  According to the walnut splitter of claim 1, comprising a box-shaped housing capable of accommodating walnuts, and a pressing portion having a screw rod supported by a support portion provided on a side plate of the housing. The walnuts can be reliably pressed without dropping the walnuts simply by accommodating the walnuts between the side plate and the contact portion in the housing and screwing the screw rods. For this reason, according to this walnut cracker, the operation | work which breaks a shell can be performed efficiently by the part which walnuts do not fall. In addition, according to this walnut cracker, even if a portion of the shell is crushed by pressing the walnuts in a state where the walnuts are contained in the housing, It is possible to reliably prevent scattering to the surroundings. Furthermore, according to this walnut splitting device, the abutment portion is attached to the tip portion so as to be rotatable relative to the tip portion of the screw rod, so that the abutment portion is in contact with the walnuts. When the threaded rod is screwed in, the threaded rod can only be rotated relative to the abutting portion, and the walnut can be pressed at the abutting portion while keeping the abutting portion not rotating relative to the walnut. it can. For this reason, according to this walnut cracker, it is possible to reliably avoid a situation where the shell is crushed due to rotation of the abutting portion with respect to the walnut, resulting in a separated state.

  Further, according to the walnut splitter according to claim 2, the concave portion is provided in the central portion of the abutting portion, so that the outer peripheral surface of the walnut is recessed when the abutting portion abuts on the walnuts accommodated in the housing.

As a result, the walnut shell can be reliably broken.

  Moreover, according to the walnut splitter according to claim 3, by providing the concave portion on the inner surface of the side plate, when the walnuts accommodated in the housing are pressed by the pressing portion, the outer peripheral surface of the walnut becomes the inner surface of the concave portion. As a result, the walnut shell can be reliably prevented from being displaced (moved) with respect to the side plate when the walnut is pressed by the pressing portion. Can be reliably broken.

  Moreover, according to the walnut splitter of claim 4, since the knob is formed in a cylindrical shape, the manufacturing process of the knob can be simplified, so that the manufacturing cost of the knob and the walnut splitter can be reduced. it can. In addition, the cylindrical shape is easier to adjust to the hand when grasped than the square shape, so that the operability can be improved accordingly.

It is a perspective view which shows the structure of the walnut cracker 1. FIG. It is explanatory drawing explaining the usage method of the walnut cracker. It is a top view of the walnut 100 which shows the state where the shell 101 was cracked.

  Hereinafter, embodiments of the walnut cracker will be described with reference to the accompanying drawings.

  First, the structure of the walnut cracker 1 shown in FIG. 1 as an example of the walnut cracker will be described. The walnut cracker 1 is an instrument for breaking the shell 101 (see FIG. 3) of the walnut 100 (see FIGS. 2 and 3) and taking out seeds (cotyledons) 102 (see the same figure), as shown in FIG. Further, the housing 2 and the pressing portion 3 are provided.

  As shown in FIG. 1, the housing 2 is formed in a box shape having an opening on one side of a cube, and has a housing portion 2 a capable of housing walnuts. Specifically, the housing 2 includes a rectangular bottom plate 21 and side plates 22a to 22d (hereinafter, also referred to as “side plates 22” when not distinguished from each other) standing on four edges of the bottom plate 21. It is configured.

  Moreover, the housing | casing 2 is produced using a metal plate (for example, an iron plate and a stainless plate) as an example. In this example, the casing 2 is manufactured by bending a single metal plate and welding the edges of the side plates 22a to 22d.

  Further, as shown in FIG. 2, an insertion hole through which a screw rod 31 of a pressing portion 3 to be described later can be inserted in a central portion of the side plate 22 a (one of a pair of side plates 22 a and 22 b facing each other) of the housing 2. 23 is formed. Further, as shown in FIG. 1, the side plate 22a is provided with a support portion 24 having a screw hole 24a into which the screw rod 31 can be screwed. In this case, the support portion 24 is disposed on the outer surface of the side plate 22a so that the screw hole 24a communicates with the insertion hole 23 of the side plate 22a, and is fixed to the side plate 22a by welding.

  In addition, as shown in FIGS. 1 and 2, the walnut 100 is faced (or a plurality of pieces) at the center of the inner surface of the side plate 22b (the other of the pair of side plates 22a and 22b facing each other) facing the side plate 22a. A recess 25 is provided for support (at the point of contact). By providing the concave portion 25, when the walnut 100 accommodated in the accommodating portion 2 a of the housing 2 is pressed by the pressing portion 3, the outer peripheral surface of the walnut 100 is faced to the inner surface of the concave portion 25 (or a plurality of walnuts 100). This prevents the walnut 100 from being displaced (moved) with respect to the side plate 22b when the walnut 100 is pressed by the pressing portion 3, as will be described later.

  The pressing portion 3 is a member for pressing the walnut 100 accommodated in the housing 2 to break the shell 101. As shown in FIGS. 1 and 2, the screw rod 31, the abutting portion 32, and the knob 33 are provided. It is prepared for.

  As shown in FIGS. 1 and 2, the screw rod 31 is a rod-shaped member (full screw) in which a thread of a right-hand thread whose front end portion 31 a moves forward by clockwise rotation (clockwise) is formed on the outer peripheral surface. It is configured. Further, the screw rod 31 is screwed into the screw hole 24 a of the support portion 24 provided on the side plate 22 a of the housing 2, and the support portion 24 is in a state where the distal end portion 31 a is positioned in the housing portion 2 a of the housing 2. Is supported by. For this reason, when the screw rod 31 is rotated clockwise, the protruding amount of the distal end portion 31a protruding from the side plate 22a of the housing 2 into the housing portion 2a of the housing 2 increases, and counterclockwise (reverse) When rotated clockwise, the amount of protrusion of the tip 31a decreases.

  The abutting portion 32 is a member that abuts against the walnut 100 accommodated in the accommodating portion 2a of the housing 2 (see FIG. 2), and as shown in FIGS. Are attached to the tip 31a in a relatively rotatable state (can be idle). In this case, as an example, the contact portion 32 is obtained by overlapping and joining (for example, joining by welding) plate members 41 and 42 having a spherical crown shape (a shape constituted by a part of a sphere) having different curvatures. As shown in FIG. 2, the whole is provided with a concave portion 32a in the central portion (the central portion is slightly recessed) and is formed in a circular thick plate shape as a whole. By providing the concave portion 32a in the central portion of the contact portion 32, when the contact portion 32 contacts the walnut 100, the outer peripheral surface of the walnut 100 faces the inner surface of the concave portion 32a (or at a plurality of contact points). Thus, as described later, the positional deviation of the walnut 100 with respect to the abutting portion 32 when the walnut 100 is pressed by the pressing portion 3 is prevented.

  The knob 33 is a member that is gripped when the screw rod 31 is rotated, and is attached to the proximal end portion 31b of the screw rod 31 as shown in FIGS. In this case, as shown in FIG. 1, the knob 33 is formed in a cylindrical shape as an example. Since the knob 33 is formed in a cylindrical shape, the manufacturing process of the knob 33 can be simplified, so that the manufacturing cost can be reduced. In addition, since the cylindrical shape is easier to adjust to the hand when grasped than the square shape, the operability is improved accordingly. Furthermore, weight reduction of the knob 33 is achieved by forming in the cylindrical shape. As shown in FIG. 1, the knob 33 is provided with unevenness (as an example, unevenness formed by knurling) that functions as a slip stopper. In the figure, only a part of the region where the unevenness is formed is shown in an enlarged manner.

  Next, the usage method of the walnut cracker 1 is demonstrated with reference to drawings.

  First, the knob 33 of the pressing part 3 is gripped and rotated counterclockwise. At this time, the screw rod 31 is rotated, and as shown in FIG. 1, the protruding amount of the tip portion 31a from the side plate 22a of the housing 2 decreases, and the contact portion 32 attached to the tip portion 31a. Is separated from the side plate 22b and close to the side plate 22a.

  Next, as shown in FIG. 2, the walnut 100 is accommodated between the abutting portion 32 and the side plate 22 b in the accommodating portion 2 a of the housing 2. At this time, as shown in the figure, the longitudinal direction of the walnut 100 is perpendicular to the axis of the screw rod 31, and the joining portions of the two halves 101a and 101b (see FIG. 3) constituting the walnut 100 are housings. It is preferable to accommodate the walnut 100 in a posture that is parallel (or almost parallel) to the bottom plate 21 of the body 2, and by this accommodation, the shell 101 is cleanly divided into two (two half-shells as will be described later). The body 101a, 101b).

  Subsequently, the knob 33 of the pressing unit 3 is gripped and rotated clockwise. At this time, the screw rod 31 is rotated and screwed into the screw hole 24a of the support portion 24, whereby the protruding amount of the tip portion 31a from the side plate 22a of the housing 2 is increased and attached to the tip portion 31a. The contact portion 32 that is in contact with the walnut 100.

  Next, the knob 33 is further rotated to screw the screw rod 31 further (the amount of protrusion of the tip portion 31a is further increased). As a result, the walnut 100 moves to the side plate 22b side, and then the walnut 100 is sandwiched between the contact portion 32 and the side plate 22b as shown in FIG.

  Next, the walnut 100 is pressed by the contact portion 32 by further rotating the knob 33 in this state. In this case, in the walnut splitting device 1, the side plate 22b is provided with a recess 25, and the contact portion 32 is provided with a recess 32a. For this reason, the outer peripheral surface of the walnut 100 is in contact with the inner surface of the recess 25 and the inner surface of the recess 32a (or at a plurality of contact points), thereby causing the misalignment of the walnut 100 with respect to the side plate 22b and the contact portion 32. Is prevented.

  In this case, in the walnut splitting device 1, the contact portion 32 is attached to the tip portion 31 a in a state of being rotatable relative to the tip portion 31 a of the screw rod 31. Therefore, when the abutting portion 32 abuts on the walnut 100 and pressing against the walnut 100 is started, even if the screw rod 31 is screwed with the rotation of the knob 33, the screw rod 31 is against the abutting portion 32. The contact part 32 presses the walnut 100 without rotating with respect to the walnut 100. For this reason, the situation where the shell 101 is crushed by the contact portion 32 rotating with respect to the walnut 100 to be in a separated state is avoided.

  Subsequently, the joint portions of the halves 101a and 101b constituting the shell 101 are deformed by the pressing force of the abutting portion 32 against the walnut 100, and the joint portions are separated along with this deformation, whereby the shell 101 is separated into two halves. Divided into bodies 101a and 101b. Here, since the walnut 100 is housed in the housing portion 2a in a posture in which the joint portions of the half bodies 101a and 101b are parallel to the bottom plate 21 of the housing 2, the pressing force by the contact portion 32 is mainly used as the joint portion. Act on. In this case, since the joining portions of the half bodies 101a and 101b have high breaking strength, the joining portions are separated before the joining portions are crushed by pressing. That is, the walnut 100 is housed in the housing portion 2a and the walnut 100 is pressed by the pressing portion 3 as described above, so that the shell 101 is cleanly divided into two halves 101a and 101b with little crushing. Moreover, in this walnut cracker 1, since the shell 101 is cracked (shell 101 is divided) in the housing 2 (in the accommodating portion 2a), even if a part of the shell 101 is crushed, it is crushed. The shell 101 stops in the accommodating portion 2a, and scattering to the surroundings is reliably prevented.

  Next, the knob 33 is rotated counterclockwise so that the contact portion 32 attached to the tip portion 31a is separated from the side plate 22b. Subsequently, the halves 101a and 101b are taken out from the container 2a, and the seeds 102 are taken out from the halves 101a and 101b. Thus, the work of splitting one walnut 100 is completed. Then, when breaking another walnut 100, the above procedure is repeated.

  When the walnut 100 is accommodated in the accommodating portion 2 a of the housing 2, the walnut 100 may be accommodated in a posture in which the joining portions of the two halves 101 a and 101 b are perpendicular to the bottom plate 21 of the housing 2. it can. In this case, even if the shell 101 is crushed by the pressing of the pressing portion 3 against the walnut 100, the crushed shell 101 stops in the housing 2 and is reliably prevented from scattering out of the housing 2. Moreover, the walnut 100 can also be accommodated in the accommodating part 2a in the attitude | position which rotated the walnut 100 shown in FIG. 2 90 degrees, ie, the attitude | position where the elongate direction of the walnut 100 follows the axis line of the screw rod 31. Even when the walnut 100 is accommodated in this posture, the concave portion 25 is formed in the side plate 22b and the concave portion 32a is formed in the abutting portion 32. Therefore, when the walnut 100 is pressed by the pressing portion 3, Position shift (movement) of the walnut 100 with respect to the contact portion 32 can be reliably prevented.

  As described above, according to the walnut splitter 1, the press having the box-shaped housing 2 that can accommodate the walnut 100 and the screw rod 31 supported by the support portion 24 provided on the side plate 22 a of the housing 2. By providing the portion 3, the walnut 100 is not dropped by simply housing the walnut 100 between the side plate 22b and the contact portion 32 in the housing portion 2a of the housing 2 and screwing the screw rod 31. The walnut 100 can be pressed reliably. For this reason, according to this walnut splitter 1, the operation | work which breaks the shell 101 can be efficiently performed as much as the walnut 100 does not fall. Further, according to the walnut splitter 1, by pressing the walnut 100 and breaking the shell 101 in a state where the walnut 100 is housed in the housing portion 2a of the housing 2, a part of the shell 101 is crushed by the pressing. Even so, the crushed shell 101 can be stopped in the housing portion 2a to reliably prevent scattering to the surroundings. Furthermore, according to this walnut splitting device 1, the abutment portion 32 is attached to the distal end portion 31a in a state of being rotatable relative to the distal end portion 31a of the screw rod 31, so that the abutment portion 32 has the walnut 100. When the screw rod 31 is screwed in a state of being in contact with the screw rod 31, the screw rod 31 is merely rotated relative to the contact portion 32, and the contact portion 32 is not rotated relative to the walnut 100. In addition, the walnut 100 can be pressed by the contact portion 32. For this reason, according to the walnut splitting device 1, it is possible to reliably avoid the situation in which the shell 101 is crushed by the contact portion 32 rotating with respect to the walnut 100 to be in a separated state.

  Further, according to this walnut splitting device 1, the concave portion 32 a is provided in the central portion of the abutting portion 32, so that when the abutting portion 32 abuts on the walnut 100 accommodated in the accommodating portion 2 a of the housing 2, Since the outer peripheral surface of the walnut 100 can be brought into contact with the inner surface of the recess 32a (or at a plurality of contact points), the position of the walnut 100 relative to the contact portion 32 when the walnut 100 is pressed by the pressing portion 3 As a result of reliably preventing displacement (movement), the shell 101 of the walnut 100 can be reliably broken.

  Moreover, according to this walnut splitting device 1, by providing the recess 25 on the inner surface of the side plate 22 b, when the walnut 100 accommodated in the accommodating portion 2 a of the housing 2 is pressed by the pressing portion 3, Since the outer peripheral surface can be brought into contact with the inner surface of the concave portion 25 (or at a plurality of contact points), the positional deviation (movement) of the walnut 100 with respect to the side plate 22b when the walnut 100 is pressed by the pressing portion 3 is prevented. As a result of being able to reliably prevent, the shell 101 of the walnut 100 can be reliably broken.

  Moreover, according to this walnut splitting device 1, since the knob 33 is formed in a cylindrical shape, the manufacturing process of the knob 33 can be simplified, so that the manufacturing cost of the knob 33 and the walnut splitting device 1 can be reduced. Can do. In addition, the cylindrical shape is easier to adjust to the hand when grasped than the square shape, so that the operability can be improved accordingly.

  The configuration of the walnut cracker is not limited to the above configuration, and can be changed as appropriate. For example, although an example in which the housing 2 is manufactured using a metal plate has been described above, the housing 2 can also be manufactured using other materials such as a resin.

  In addition, although the example in which the concave portion 25 is provided in the side plate 22b has been described above, a configuration in which the concave portion 25 is not provided may be employed. Further, although the example in which the contact portion 32 formed by joining the two plate members 41 and 42 is used is described above, the contact portion 32 formed by one member (for example, a plate material) can also be used. Moreover, the shape of the contact part 32 is not limited to a circle, and may be an ellipse or a rectangle, or a polygon other than a rectangle. Moreover, the contact part 32 which does not provide the recessed part 32a is also employable.

  In addition, the shape of the knob 33 is not limited to a cylindrical shape, and may be a columnar shape, or may be a cylindrical shape or a columnar shape having a polygonal outer periphery.

  Further, the configuration example in which the support portion 24 formed separately from the side plate 22a is fixed to the side plate 22a has been described above. However, the side plate 22a is formed thick and a screw hole into which the screw rod 31 can be screwed is formed in the insertion hole 23. Instead, a configuration formed on the side plate 22a, that is, a configuration in which the side plate 22a itself functions as a support portion may be employed.
