  Here, a process in which the chestnut 20 is cut by the chestnut cutting machine 1 will be described with reference to FIGS.

  First, a plurality of chestnuts 20 and 20 are continuously carried into the rotating body 2 of the cutting unit 1a by the carrying-in unit 1b. Specifically, the chestnuts 20 and 20 placed on the carry-in portion 1b fall from the tip of the carry-in portion 1b (specifically, the tip facing the rotary body 2) to the rotary body 2 side, One is accommodated in each of the three accommodating recesses 3a and 3a (see FIGS. 11 and 12). At this time, in the chestnut 20 that has fallen on the separating portion 7 (in the illustrated embodiment, the extending portions 2d and 2d that are in contact with each other) of the rotating body 2, the inclined surfaces 7a and 7a ( In the illustrated embodiment, the outer peripheral surfaces of the extending portions 2d and 2d that are in contact with each other are slid to move toward the chestnut accommodating portion 3 and are accommodated in the accommodating recess 3a. Then, when the rotating body 2 rotates around its axis (clockwise in FIG. 11), the housing recesses 3a and 3a housing the chestnuts 20 and 20 move to the rotary blade 4 side.

  Here, the chestnut flipping portion 13 disposed above the rotating body 2 is also rotated in the same direction as the rotating direction of the rotating body 2 (clockwise direction in FIG. 11). If it fails to enter the accommodation recess 3a due to, for example, dropping onto another chestnut 20 accommodated in the recess 3a, the failed chestnut 20 is moved into the rotating chestnut repelling portion 13 (in detail, the blade It will be bounced by the part 13b) and will be put into the empty accommodation recess 3a.

  Thus, the chestnuts 20 and 20 accommodated in the accommodating recesses 3a and 3a of the rotating body 2 are sent to the rotating blade 4 side with the rotation of the rotating body 2 and are cut vertically by the rotating blade 4. Thus, a pair of half chestnuts 21 and 21 are formed (see FIGS. 11 and 13). And the formed half chestnuts 21 and 21 are sent to the chestnut separation part 7 side (in the illustrated embodiment, the second plate member 11 side) as the rotating body 2 rotates. As a result, the chestnut separation portion 7 (in the illustrated embodiment, the second plate member 11 and the thin portion 10b of the first plate member 10) is placed between the cut surfaces 21a and 21a of the pair of half chestnuts 21 and 21. The halved chestnuts 21 and 21 enter relatively, and are separated by the chestnut separation portion 7 (in the illustrated embodiment, the second plate member 11 and the thin portion 10b of the first plate member 10). Then, it is sent to the chestnut fall unit 6 (see FIG. 11 and FIG. 14).

  Here, when the half chestnut 21 is about to jump out of the housing recess 3a by an external force such as gravity or centrifugal force caused by the rotation of the rotating body 2, the half chestnut 21 is a cover member. 12 and is guided to the chestnut fall portion 6 by sliding down the inner surface of the cover member 12 as the rotating body 2 rotates (see FIG. 11). In addition, when the cut surface 21a of the half chestnut 21 is sticky to the chestnut separation portion 7 (in the illustrated embodiment, the second plate member 11 and the thin portion 10b of the first plate member 10), The half-chestnut 21 is sent to the chestnut fall portion 6 so as to be pushed by the inner wall surface (particularly, the side wall portion 3c) of the housing recess 3a. In the illustrated embodiment, the pair of half chestnuts 21 and 21 are substantially directly below the axial center of the rotating body 2 (specifically, the thin portion 10b of the first plate member 10 and the second plate member 11 At the boundary portion), the thin portion 10b is placed between the thin portions 10b so as to be opposed to each other and placed on the carry-out portion 5 and sent to the chestnut fall portion 6.

  And if the chestnut fall part 6 approachs relatively between the cut surfaces 21a and 21a of a pair of half-chestnuts 21 and 21, the half-chestnuts 21 and 21 will have the cut surfaces 21a and 21a on the carry-out part 5 Fall down as if facing up. Specifically, the taper surfaces 6a and 6a of the chestnut fall portion 6 are relatively between the cut surfaces 21a and 21a of the pair of half chestnuts 21 and 21 from the tip side (the other end side of the first plate member 10). Approach. More specifically, the tapered surfaces 6a and 6a gradually approach between the cut surfaces 21a and 21a so as to go from the upper side to the lower side of the pair of half chestnuts 21 and 21. Accordingly, the pair of half chestnuts 21 and 21 are inclined along the tapered surfaces 6a and 6a of the chestnut fall portion 6 (see FIG. 15), and the cut surfaces 21a and 21a are moved upward on the carry-out portion 5. It falls as if it faces. Thus, the half chestnuts 21 and 21 that have fallen on the carry-out unit 5 are carried out to the next step by the carry-out unit 5 with the cut surfaces 21a and 21a facing upward (see FIG. 11).

  By the way, in the process in which the half-split chestnut 21 is sent to the chestnut fall part 6, for example, a part of the pulp that has been crushed by the cutting is the inner wall surface (specifically, the side wall parts 3c, 3d and the bottom part 3b) As a result, the half chestnut 21 may try to pass through the chestnut fall portion 6 as the rotating body 2 rotates while being accommodated in the accommodation recess 3a. At this time, the half-chestnut 21 stuck to the chestnut is forcibly discharged from the housing recess 3a so as to be scooped by the chestnut discharge portion 8 (specifically, the discharge plate 8a) disposed above the chestnut fall portion 6. The

  Next, the function and effect of the chestnut cutting machine 1 will be described. In this chestnut cutting machine 1, since the half chestnuts 21, 21 are provided with a chestnut fall section 6 that tilts the cut surfaces 21 a, 21 a so as to face upward on the carry-out section 5, When checking the cut surface 21a of the split chestnut 21, it is not necessary to turn the half-split chestnut 21 so that the cut surface 21a faces upward, and the chestnut sorting operation can be easily performed.

  Moreover, since the chestnut repelling part 13 is arranged above the rotating body 2, the chestnut 20 that has failed to enter the housing recess 3a in the process of moving from the carrying-in part 1b to the rotating body 2 is flipped into the housing recess 3a. be able to.

  Further, a chestnut separating portion 7 (in the illustrated embodiment, the second plate member 11 and the thin portion 10b of the first plate member 10) is provided between the rotary blade 4 and the chestnut fall portion 6. Therefore, the pair of half chestnuts 21 and 21 are separated by the chestnut separation part 7 (in the illustrated embodiment, the second plate member 11 and the thin part 10b of the first plate member 10). It will be sent to the fall part 6, and the said chestnut fall part 6 can be made to approach relatively between the cut surfaces 21a and 21a of a pair of half chestnuts 21 and 21 reliably. Further, since the chestnut separating portion 7 (specifically, the second plate member 11) is provided with the plurality of through holes 11a and 11a, the chestnut separating portion 7 ( Specifically, it is possible to suppress the adhesion to the second plate member 11) and to easily send the half-split chestnut 21 to the chestnut fall section 6.

  In addition, since the cover member 12 is provided on the outer peripheral side of the rotating body 2, the half chestnut 21 that is about to jump out of the housing recess 3 a is received by the cover member 12, and further to the chestnut fall portion 6. The half chestnut 21 can be surely sent to the chestnut defeating unit 6. In addition, since the cover member 12 has the warped portion 12b on the upper end side, the chestnut 20 is located at the upper end of the cover member 12 even when the chestnut 20 protrudes slightly from the housing recess 3a. Without being caught on the rotary blade 4, it is reliably sent to the rotary blade 4 side.

  The chestnut fall portion 6 is formed with the tapered surfaces 6a and 6a, and the tapered surfaces 6a and 6a are inclined so that the distal end side (the other end side of the first plate member 10) is located upward. Therefore, the tapered surfaces 6a and 6a gradually approach between the cut surfaces 21a and 21a so as to go from the upper side to the lower side of the pair of half chestnuts 21 and 21. The half-split chestnuts 21 and 21 easily fall down with the cut surfaces 21a and 21a facing upward on the carry-out portion 5.

  Moreover, the chestnut accommodating parts 3 and 3 and the chestnut fall parts 6 and 6 are located at a predetermined distance, and the half chestnuts 21 and 21 fallen by the adjacent chestnut fall parts 6 and 6 interfere with each other. There is nothing that prevents them from collapsing. Further, the inclined portions 9a and 9a (in the illustrated embodiment, the contact portions with each other) are separated from the partition portion 9 (the extending portions 2d and 2d in contact with each other in the illustrated embodiment) separating the chestnut housing portions 3 and 3. Since the outer peripheral surfaces of the projecting portions 2d and 2d are formed, the chestnut 20 is easily accommodated in the accommodating recess 3a.

  Moreover, since the chestnut discharge part 8 is arranged above the chestnut fall part 6, about the half-chestnut 21 stuck to the inner wall surface (in detail, side wall part 3c, 3d and bottom part 3b) of the accommodation recessed part 3a Also, it can be forcibly discharged from the housing recess 3a and carried out.

  In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, the carry-out unit 5 may not be configured separately from the chestnut cutting machine 1, and may be configured integrally with the chestnut cutting machine 1 and driven by the driving unit 1c. Good. Further, the chestnut cutting machine 1 may not include the carry-in unit 1b. For example, the carry-in unit may be configured separately from the chestnut cuter 1. Moreover, each component in the chestnut cutting machine 1 does not necessarily have the shape and arrangement shown in the illustrated embodiment, and may be appropriately changed as necessary.

  Moreover, the rotary body 2 does not need to be formed in a substantially cylindrical shape having a substantially circular shape when viewed from the side, and may be, for example, a polygonal column shape such as a rectangular column including a rectangular parallelepiped or other shapes. In the illustrated embodiment, the rotator 2 is formed with four chestnut accommodating portions 3 arranged in the axial direction, but two, three, or five or more are arranged. Further, it may be formed, and furthermore, only one chestnut container 3 may be formed on the rotating body 2. Note that the rotary blade 4, the chestnut fall unit 6, the chestnut separation unit 7, the chestnut discharge unit 8, the first plate member 10, and the second plate member 11 are plural or singular so as to correspond to the chestnut storage unit 3. It only has to be deployed.

  Further, the inclined surface 9a, 9a may not be formed in the separating portion 9 of the rotating body 2, for example, the separating portion 9 is adjacent to the chestnut accommodating portion 3, with the separating portion 9 interposed therebetween, 3 may be formed so as to go straight in a direction parallel to the axial direction.

  Moreover, the accommodation recessed part 3a does not need to be formed so that the width | variety may become narrow as the bottom part 3b side, for example, may be formed so that it may become a fixed width | variety toward the bottom part 3b side.

  In the illustrated embodiment, the thick portion 10a of the first plate member 10 is formed so that the overall plate thickness is slightly narrower than the width dimension of the first groove 3f. For example, as shown in FIG. 16 to FIG. 18, the portion other than the portion inserted into the first groove 3 f of the thick portion 10 a of the first plate member 10 is not necessarily required. The plate thickness may be formed to be substantially the same as or larger than the width of the first groove 3f. In the first plate member 10, the thick portion 10a is provided on the other end side (specifically, on the other end side and extending from the middle portion to the upper portion), the first groove 3f. The 1st thick part 10c used as the part inserted in is provided. The plate thickness of the first thick portion 10c is slightly narrower than the width dimension of the first groove 3f. Further, the second thick part formed so that the part other than the first thick part 10c of the thick part 10a is substantially the same as or larger than the width dimension of the first groove 3f. 10d. Here, when the first plate member 10 is manufactured, for example, the entire thick portion 10a is formed so that the plate thickness is substantially the same as or larger than the width dimension of the first groove 3f. The first portion is then formed by, for example, cutting so that the thickness of the portion inserted into the first groove 3f is slightly narrower than the width dimension of the first groove 3f. The thick part 10c will be formed. In the illustrated embodiment, the tapered surfaces 6a, 6a are located closer to the other end side than the first plate member 10 shown in FIG. Further, the boundary portion between the first thick portion 10c and the second thick portion 10d is formed so that the plate thickness gradually increases from the first thick portion 10c toward the second thick portion 10d. The left and right boundary surfaces Q and Q are step surfaces which form steps so as to extend from the upper end of the first plate member 10 to the tapered surfaces 6a and 6a in an arc shape in a side view. (See FIG. 17).

  Moreover, the 1st board member 10 does not need to be arrange | positioned so that it may insert in the accommodation recessed part 3a (specifically 1st groove | channel 3f) of the chestnut accommodating part 3, for example, the outer peripheral part 2a of the rotary body 2 It may be arranged so as to be located at a slight distance from. Here, in the case where the first plate member 10 is arranged so as to be located slightly apart from the outer peripheral portion 2a of the rotating body 2, the entire plate thickness of the thick portion 10a is equal to the first groove. You may form so that it may become substantially the same as the width dimension of 3f, or more. Moreover, the 2nd board member 11 does not need to be arrange | positioned so that the 1st board member 10 (specifically thin part 10b) may be followed, for example, the 2nd board member 11 and the 1st board member 10 (In detail, you may arrange | position so that a clearance gap may be made between (thin wall part 10b). For example, when the rotary blade 4 and the chestnut fall part 6 are close to each other, the chestnut separation part 7 is not necessarily provided.

  Further, the chestnut fall portion 6 does not necessarily have the tapered surfaces 6a and 6a, and instead of the tapered surfaces 6a and 6a, for example, it is not symmetrically inclined and the inclination angle is different. Such a slope may be formed on the left and right, and further, a stepped portion, a protruding portion, or an uneven portion protruding outward may be formed instead of a tapered surface or a slope. Moreover, the taper surface 6a does not need to be formed obliquely so as to be positioned higher toward the tip side, and may be formed to extend in the vertical direction. Further, in the illustrated embodiment, the chestnut fall portion 6 and the chestnut separation portion 7 are formed by the first plate member 10 and the second plate member 11, but it is not always necessary to have such a configuration. The chestnut faller 6 and the chestnut separator 7 may be formed by a single plate member. Or the chestnut fall part 6 and the chestnut separation part 7 may each be formed by one board member.

  Further, the cover member 12 may not be provided with the warped portion 12 b on the upper end side, and the upper end side may be formed along the outer peripheral portion 2 a of the rotating body 2.
