Description

  The present invention relates to a sheller used to peel peanut shells.

  Heretofore, as food produced from peanuts, foods obtained by frying peanut flakes and foods obtained by roasting peanut flakes are known. In any of these foods, it is necessary to peel peanut shells in the manufacturing process, and since this work requires labor, there is a need for a machine capable of peeling peanut shells.

  Thus, for example, Patent Document 1 discloses a molting machine for molting seeds such as soybeans. The stripping machine comprises a low speed rotor and a bellows-like high speed rotor rotating at a higher speed than the low speed rotor. In this uncoating machine, the water-expanded seeds are transported to the adjacent part between the low-speed rotating body and the bellows-like high-speed rotating body by the rotation of the low-speed rotating body. When the seed is conveyed to the above-mentioned adjacent part, the difference between the rotational speeds of the high-speed rotor and the low-speed rotor acts as a twisting stress, and the seed rubs by the elastic body covering the outer periphery of the bellows-like high-speed rotor. The seeds are molted.

The carriage 7 includes a rectangular lower plate 7a, pillars 7b extending upward from four corners of the upper surface of the lower plate 7a, and a rectangular upper plate 7c connected and fixed to the upper end of the pillar 7b. Casters 7d are attached to the four corners of the lower surface of the lower plate 7c, and the carriage 7d is mounted on the floor surface so that the carriage 7 is supported on the floor surface and can be moved.

  The shell peeling machine 1 includes a hopper 4, a rotation means 5 (FIG. 1), and a clearance adjustment means 6 (FIG. 2) in addition to the inner cylinder 2 and the outer cylinder 3 described above (FIG. 2 and FIG. 3) The state which removed the rotation means 5 is shown). As shown in FIG. 2, the gap adjusting means 6 is disposed between the lower plate 7a and the upper plate 7c. The inner cylinder 2, the outer cylinder 3, the hopper 4 and the rotation means 5 are disposed above the upper plate 7 c (see FIG. 1 for the rotation means 5). In the upper plate 7c, a through hole 7e is formed in a range (a range inward of the inner peripheral edge of the outer cylinder 3) below the gap S and the inner cylinder 2. The outer cylinder 3 is stationary fixed in the outer range of the through hole 7e in the upper plate 7c.

  FIG. 4 is an enlarged sectional view showing the inner cylinder 2 and the outer cylinder 3 (FIG. 4 shows a state in which the hopper 4 and the rotating means 5 are removed).

  The inner cylinder 2 is formed of metal such as stainless steel or iron. The inner cylinder 2 has a cylindrical shape in which the outer diameter increases toward the lower side, and the axis G of the inner cylinder 2 extends in the vertical direction. The upper end of the inner cylinder 2 is closed by a top wall 9. The top wall 9 is composed of a disc 90 and a flanged shaft holder 91 (hereinafter referred to as a shaft holder 91). The outer edge of the disc 90 is joined to the upper edge of the peripheral wall of the inner cylinder 2. A through hole is formed at the position of the disc 90 on the axis G (the center position of the disc 90). The shaft holder 91 has a tubular shape whose upper end is closed and which opens downward. At the lower end of the shaft holder 91, an outwardly projecting flange 92 is provided. The flange 92 is placed on the disc 90 so that the through hole of the disc 90 is located below the cavity of the shaft holder 91, and the flange 92 is fixed to the disc 9 with a bolt or the like. The holder 91 extends along the axis G. The top wall 9 of the inner cylinder 2 configured as described above is supported by the gap adjusting means 6 (FIG. 2), whereby the inner cylinder 2 is positioned above the upper plate 7c. The gap adjusting means 6 can adjust the width of the gap S by changing the relative positional relationship between the inner cylinder 2 and the outer cylinder 3 in the vertical direction. Details of the gap adjusting means 6 will be described later.

  As shown in FIG. 4, the inner cylinder 2 is formed with a plurality of first holes 10 opening in the outer peripheral surface 2 a. The first hole 10 is a through hole extending from the outer peripheral surface 2a of the inner cylinder 2 to the inner peripheral surface 2b, and is long in the vertical direction (see FIG. 2 for the inner peripheral surface 2b of the inner cylinder 2).

  The outer cylinder 3 has a cylindrical shape in which the inner diameter increases as it goes down. The outer cylinder 3 is coaxially disposed with the inner cylinder 2 and surrounds the inner cylinder 2 with a gap S between the outer cylinder 3 and the outer peripheral surface 2 a of the inner cylinder 2. As shown in FIG. 4, the inclination angle θa of the outer peripheral surface 2a of the inner cylinder 2 with respect to the horizontal plane is smaller than the inclination angle θb of the inner peripheral surface 3a of the outer cylinder 3 with respect to the horizontal surface. It is so narrow. Further, as shown in FIG. 4, a large number of substantially circular second holes 11 are formed in the inner peripheral surface 3 a of the outer cylinder 3.

  The outer cylinder 3 is one in which two halves 12 shown in FIG. 5 are butted. The half body 12 includes an inner layer body 13 and an outer layer body 14. The inner layer body 13 and the outer layer body 14 are formed of a metal such as stainless steel or iron. The inner layer body 13 constitutes a half circumference of the inner peripheral surface 3 a of the outer cylinder 3, and the second hole 11 is formed in the inner layer body 13.

  The outer layer 14 has an outer peripheral wall 15 having a U-shape in a plan view, a support plate 16 disposed on the inner side of the outer peripheral wall 15 having substantially the same shape as the inner layer 13, and an upper end of the outer peripheral wall 15. An upper wall 17 connecting the upper end of the support plate 16 and a lower wall 18 connecting the lower end of the outer peripheral wall 15 and the lower end of the support plate 16 are provided. The outer layer body 14 supports the inner layer body 13 by fixing the support plate 16 to the upper surface of the inner layer body 13 with a screw or the like. By providing the outer layer body 14, the reduction in strength of the inner layer body 13 due to the formation of the second hole 11 is compensated. When the outer layer 14 is formed of iron, it is preferable to apply a coating to the surface of the outer layer 14 in order to increase the hardness of the outer layer 14 or to prevent corrosion.

  The outer cylinder 3 is formed by butt-connecting the two halves described above and connecting the ends of the outer peripheral wall 15 with a screw. In the outer cylinder 3 formed in this manner, the inner peripheral surface 3 a is constituted by the two inner layer bodies 13, and the outer sides of the two inner layer bodies 13 are covered with the two outer layer bodies 14.

  FIG. 7 is a photograph showing the hopper 4 and the rotation means 5. FIG. 8 is a perspective view showing the hopper 4 and the rotation means 5 (FIG. 8 shows a state in which the rotation means 5 is disassembled).

  As shown in FIG. 2, FIG. 7 and FIG. 8, the hopper 4 is disposed above the gap S. The hopper 4 has an opening at the upper end and the lower end, and peanuts are introduced into the hopper 4 from the opening at the upper end. Since the smaller the inner diameter of the hopper 4 is, the peanuts introduced into the hopper 4 fall smoothly to the lower side of the hopper 4. The opening rim of the lower end of the hopper 4 is joined to the opening rim of the upper end of the outer cylinder 3, and the upper end of the inner cylinder 2 is closed by the top wall 9. From the upper end of S, it enters into the gap S.

  The rotation means 5 is composed of a handle capable of rotating the inner cylinder 2 around the axis G (hereinafter, the handle is the rotation means 5 and is referred to as “handle 5”). The handle 5 includes a handle shaft 20 fixed to the top wall 9 of the inner cylinder 2 and four handle arms 21 radially extending from the upper end of the handle shaft 20. The handle shaft 20 has a tubular shape that opens downward. The shaft holder 91 provided on the top wall 9 of the inner cylinder 2 is inserted into the inside of the handle shaft 20, and the handle shaft 20 is fixed to the shaft holder 91 by a bolt or the like. It will be extended. Further, in the state where the handle shaft 20 is fixed to the shaft holder 91 as described above, the upper end of the handle shaft 20 is positioned above the upper edge of the hopper 4.

Each of the four handle arms 21 extends horizontally from the upper end of the handle shaft 20, and the tip extends out of the hopper 4. Each handle arm 21 includes a bracket 22 integral with the handle shaft 20, a sleeve 24 to which the bracket 22 is connected on one side, and a bracket 23 connected to the other side of the sleeve 24. The brackets 22 and 23 each have a plate shape having a rectangular cross section. A plurality of tap holes 25 are formed on the upper surface of the bracket 22 at intervals in the longitudinal direction. A plurality of tap holes 26 are formed on the upper surface of the bracket 23 at intervals in the longitudinal direction. The tip of the bracket 23 constitutes the tip of the handle arm 21, and the grip portion 27 is attached to the tip of the bracket 23. The grip portion 27 extends downward from the tip of the bracket 23. The sleeve 24 has a tubular shape with a rectangular cross section. A plurality of through holes 28 are formed in the upper wall of the sleeve 24 at intervals in the longitudinal direction. Each handle arm 21 is assembled by performing the following operations (a) and (b).
(A) Insert the bracket 22 into the inside of one side of the sleeve 24 so that one through hole 28 and one tap hole 25 face up and down, and screw in the one through hole 28 and one tap hole 25 And one side of the sleeve 24 and the bracket 22 are connected.
(B) The bracket 23 is inserted into the other side of the sleeve 24 so that one through hole 28 and one tap hole 26 face vertically, and a screw is inserted into one through hole 28 and one tap hole 26. And the other side of the sleeve 24 and the bracket 23 are connected.

  According to the handle 5 configured as described above, the user can hold the grip portion 27 and rotate the handle 5 about the axis G to rotate the inner cylinder 2 about the axis G (the outer cylinder 3 is stationary Since it is fixed, rotating the inner cylinder 2 around the axis G using the handle 5 as described above corresponds to rotating the inner cylinder 2 and the outer cylinder 3 relatively around the axis G. ).

  Further, according to the above-mentioned handle 5, the handle arm 21 can be expanded and contracted in the horizontal direction by adjusting the length for inserting the bracket 22 and the bracket 23 into the sleeve 24. If the insertion length of the brackets 22 and 23 into the sleeve 24 is shortened and the total length of the handle arm 21 is increased, the inner cylinder 2 can be rotated with a small force. The structure of the handle 5 is not limited to the above example. For example, in order to form the handle arm 21, the number of sleeves or brackets connected alternately is not limited to the above example, and may be appropriately changed according to the diameter of the hopper 4 or the like.

  As described above, the gap adjusting means 6 supports the top wall 9 of the inner cylinder 2 and changes the relative positional relationship between the inner cylinder 2 and the outer cylinder 3 in the vertical direction to thereby increase the width of the gap S. It is adjustable. As shown in FIG. 2 and FIG. 3, the clearance adjustment means 6 includes a shaft body 30, a table 31, and an elevation mechanism 32.

  The shaft 30 extends vertically along the axis G, and its upper end is fixed to the top wall 9 of the inner cylinder 2. Specifically, the upper portion of the shaft body 30 sequentially passes through the inside of the inner cylinder 2, the through hole of the disc 90 of the top wall 9, and the inside of the shaft holder 91 of the top wall 9 by bolts and spring pins. The upper end of the shaft body 30 is fixed to the shaft holder 91. The above-mentioned bolt penetrates the upper wall of the shaft holder 91 in the vertical direction, and the lower part thereof is embedded in the upper end of the shaft 30. The spring pin passes through the side wall of the shaft holder 91 and the shaft body 30 in the horizontal direction, and is fastened to the shaft holder 91 at both ends. The upper end of the shaft 30 is fixed to the shaft holder 91 by the above-described bolt and spring pin, so that the shaft 30 also rotates around the axis G as the inner cylinder 2 rotates around the axis G. The table 31 rotatably supports the lower end of the shaft 30. The elevating mechanism 32 supports the table 31 and can raise and lower the table 31. When the table 31 is raised by the raising and lowering mechanism 32, the width of the gap S is reduced by raising the shaft 30 and the inner cylinder 2. When the table 31 is lowered by the elevating mechanism 32, the width of the gap S is expanded by lowering the shaft body 30 and the inner cylinder 2.

  FIG. 9 is a front view showing the table 31 and the elevation mechanism 32. As shown in FIG. FIG. 10 is a cross-sectional view of the table 31. As shown in FIG. The detailed structure of the table 31 and the lifting mechanism 32 will be described below with reference to FIGS. 9 and 10. In FIG. 9, for convenience of explanation, a portion which is actually hidden by another member is also appropriately shown by a solid line.

  As shown in FIG. 10, the table 31 includes an upper plate 33 and a lower plate 34 which are stacked one on top of the other. At the center of the upper plate 33, a through hole 35 extending along the axis G is formed. The lower end of the shaft 30 is inserted into the through hole 35.

  A thrust bearing 36 and a radial bearing 37 are provided between the inner surface of the through hole 35 and the outer surface of the shaft 30. The thrust bearing 36 is provided on the upper side of the through hole 35, and includes an upper ring 40, a lower ring 41, and a ball 42. The upper ring 40 is joined to the lower surface of the step 43 extending around the outer periphery of the shaft 30. The lower ring 41 is joined to the upper surface of an annular protrusion 44 extending around the inner periphery of the through hole 35. The upper ring 40 and the lower ring 41 are vertically opposed to each other, and the ball 42 is rotatably disposed between them. The thrust bearing 36 described above receives the vertical load of the shaft 30 and supports the lower end of the shaft 30. The radial bearing 37 is a cylindrical body extending in the vertical direction, and is provided below the annular protrusion 44 inside the through hole 35. The radial bearing 37 is mounted on the lower plate 34 and is disposed between the inner peripheral surface of the through hole 35 and the outer peripheral surface of the shaft 30. By providing the thrust bearing 36 and the radial bearing 37 described above, the rotation of the shaft body 30 is made smooth.

  As shown in FIG. 9, the elevating mechanism 32 includes a screw shaft 50, a handle 51, a first slide block 52, a second slide block 53, a first arm 54, and a second arm 55. .

  The screw shaft 50 extends in the horizontal direction, and mutually opposite screws are formed on one side 50 a and the other side 50 b. The screw shaft 50 is rotatably supported by a pair of columns 58, 58 erected from the lower plate 7a.

  The handle 51 includes a disc 51a and a grip 51b. The center of the disc 51 a is fixed to one end of the screw shaft 50. The grip portion 51b extends outward (outside the screw shaft 50) from the peripheral edge of the disc 51a. According to the handle 51, the screw shaft 50 can be rotated in the forward rotation direction by gripping the grip portion 51b and rotating the disk 51a to one side around the circumference thereof. In addition, the screw shaft 50 can be rotated in the reverse direction by gripping the grip portion 51b and rotating the disc 51a to the other side.

  The first slide block 52 is screwed to one side 50 a of the screw shaft 50. The second slide block 53 is screwed on the other side 50 b of the screw shaft 50. The lower end of the first arm 54 is rotatably connected to the first slide block 52, and the upper end is rotatably connected to the table 31. The lower end of the second arm 55 is rotatably connected to the second slide block 53, and the upper end is rotatably connected to the table 31.

  When the screw shaft 50 is rotated in the normal direction using the handle 51, the first slide block 52 and the second slide block 53 move in the approaching direction, and the first arm 54 and the second arm 55 are moved. The table 31 is raised by rotating and standing. Then, as the shaft body 30 and the inner cylinder 2 rise with the rise of the table 31, the width of the gap S is reduced. When the screw shaft 50 is rotated in the reverse direction by using the handle 51, the first slide block 52 and the second slide block 53 move in the separating direction, and the first arm 54 and the second arm 55 The table 31 is lowered by turning and folding. Then, with the lowering of the table 31, the shaft 30 and the inner cylinder 2 are lowered, whereby the width of the gap S is enlarged.

  When the groundnut shell is peeled using the shell peeling machine 1 described above, the inner cylinder 2 is raised or lowered by the lifting mechanism 32 so that the relative positional relationship between the inner cylinder 2 and the outer cylinder 3 in the vertical direction The width of the gap S is adjusted to the width according to the size and shape of the peanut by changing. Then, peanut oil is introduced into the hopper 4 to introduce peanut oil into the gap S, and the inner cylinder 2 is rotated about the axis G using the handle 51.

  FIG. 11 is a view showing a locus K on which the peanut R moves in the space S (FIG. 11 (a) is a plan view showing the outer peripheral surface 2a of the inner cylinder 2 and FIG. 11 (b) is a space S). It is sectional drawing which cut | disconnected the outer cylinder 3 in the surface to which it follows. The peanut R that has entered the gap S is pushed downward by the subsequent peanut present on the upper side thereof, and is pushed about the axis G by the rotation of the inner cylinder 2. As a result, as shown by a locus K shown in FIG. 11, the peanut R descends spirally in the gap S. Then, the first hole 10 (FIG. 4) formed in the outer peripheral surface 2 a of the inner cylinder 2 extends in the vertical direction, whereby a part of the peanut that spirally descends in the gap S Each time it is fitted, the orientation is corrected such that the longitudinal direction extends vertically.

  And, as the width of the gap S becomes narrower toward the lower side, the peanut R falling in a spiral in the gap S has a phenomenon that it fits snugly in the gap S at any position of the gap S. At this time, the outer surface of the peanut R is strongly rubbed against the outer peripheral surface 2a of the inner cylinder 2 in which the first hole 10 is formed and the inner peripheral surface 3a of the outer cylinder 3 in which the second hole 11 is formed. Thereby, shell Ra of peanut R peels off and the size of peanut R becomes small. Then, when the size of the peanut R decreases in a spiral shape in the space S, a phenomenon in which the peanut R fits into the space S is generated again. At this time, the peanut R is strongly rubbed against the outer peripheral surface 2a of the inner cylinder 2 in which the first hole 10 is formed and the inner peripheral surface 3a of the outer cylinder 3 in which the second hole 11 is formed again. The shell Ra remaining in R peels off, and the size of the peanut R becomes smaller ((A in FIG. 11 indicates the position of the gap S where the peanut R fits first, and B, C, and D in FIG. In the shell peeling machine 1 of the present embodiment, since the gap S becomes narrower toward the lower side in this manner, the peanut R within the gap S is shown. In the process of falling in a spiral shape, it is repeated that the peanut R fits into the gap S and the peanut R is strongly rubbed against the inner cylinder 2 and the outer cylinder 3, and the shell Ra of the peanut R is gradually peeled off by this repetition. And peeled off from the groundnut Rb of the shell Ra and the groundnut R Ra spirally lowers in the space S to reach the lower end of the space S and falls from the lower end of the space S. Also, a shell smaller than the first hole 10 among the shell Ra peeled off from the peanut R Ra passes through the first hole 10 and enters the inner side of the inner cylinder 2 and falls inside the inner cylinder 2.

  On the lower side of the gap S and the inner cylinder 2, an upper chute 60 (see FIGS. 1 and 2) extending obliquely downward is provided. The groundnut Rb and shell Ra of the peanut that has passed through the gap S and the shell Ra that has passed the inside of the inner cylinder 2 fall on the upper chute 60. The groundnut R's body Rb and shell Ra of the peanut R falling on the upper chute 60 are collected along the upper chute 60 and collected in a first container (not shown) disposed outside the carriage 7 Ru. The upper chute 60 is provided with a main body portion 60 a suspended from the upper wall 7 c of the carriage 7 and an outer portion 60 b disposed outside the carriage 7. The main body 60a extends obliquely downward from the gap S and the position directly below the inner cylinder 2, and the outer side 60b is rotatably attached to the tip of the main body 60a. When the shell peeling machine 1 is used to peel off peanut shells, the outer portion 60b is inclined obliquely downward with the tip of the main portion 60a as a fulcrum. Thereby, the body Rb and shell Ra of the groundnut R dropped from the gap S and the inner cylinder 2 onto the main body portion 60a slide along the main body portion 60a and the outer side portion 60b, and the first container (not shown) ) To be collected. When the shell peeling machine 1 is not used, the outer side portion 60b is turned upside down with the tip of the main body portion 60a as a fulcrum (the state shown in FIG. 1).

  A through hole 61 (see FIG. 1) is formed in the main body portion 60a of the upper chute 60, and a lower chute 62 is provided below the main body portion 60a. The lower chute 62 extends obliquely downward and substantially in parallel with the main body 60a, and is suspended from the side edge of the main body 60a. From the above configuration, among the shells Ra sliding the main body 60 a, the shells Ra smaller in size than the through holes 61 pass through the through holes 61 and fall onto the lower chute 62. The shell Ra dropped on the lower chute 62 slides along the lower chute 62 and is collected in a second container (not shown) disposed outside the carriage 7.

  A through hole is formed in the upper chute 60 and the lower chute 62 at a position on the axis G, and a guide pipe 63 (FIG. 2) is passed through the through holes of the chutes 60 and 62. The guide pipe 63 extends vertically along the axis G, and the shaft body 30 of the gap adjusting means 6 is passed through the inside of the guide pipe 63.

  As described above, according to the shell peeling machine 1 of the present embodiment, ground peanuts are introduced into the gap S, and the inner cylinder 2 is rotated about the axis G, whereby the peanuts fall in a spiral in the gap S. Do. And, as the width of the gap S becomes narrower toward the lower side, even if various peanuts different in size and shape are inserted in the gap S, each peanut is on the path where each of the peanuts spirals down. There is a position of the gap S to be fitted. The peanut is strongly rubbed against the outer peripheral surface 2 a of the inner cylinder 2 and the inner peripheral surface 3 a of the outer cylinder 3 at the position of the gap S. Therefore, according to the shell peeling machine 1 of this embodiment, it is possible to peel various peanut shells different in size and shape.

  Further, according to the shell peeling machine 1 of the present embodiment, the first flowering hole 10 formed in the outer peripheral surface 2a of the inner cylinder 2 is long in the vertical direction, whereby the peanuts which spirally descend in the gap S are Each time a part is fitted in the first hole 10, the orientation is corrected so that the longitudinal direction extends in the vertical direction. Therefore, since the whole length of peanuts can be strongly rubbed on the inner cylinder 2 and the outer cylinder 3, the shell can be peeled over the entire length of the peanuts.

  Moreover, according to the shell peeling machine 1, the width | variety of the clearance gap S can be adjusted according to the magnitude | size and shape of a peanut by the clearance gap adjustment means 6 being provided. For this reason, shelled peanuts can be smoothly introduced into the gap from the upper end of the gap S, and peeled peanuts of the shell can be smoothly removed from the lower end of the gap. In addition, peanuts are classified into large balls, middle balls, and small balls according to their sizes, and the height of the grade is large ball> middle ball> small ball. Therefore, the upper end of the gap S is a width in which a large ball with a shell enters with a little space, and the lower end of the gap S is a width that allows the average size of the body of the large ball peeled off to come out without difficulty It is preferable to

  In order to reliably peel off the peanut shell, it is preferable to increase the number of times the peanut is inserted into the gap S and strongly rubbed against the inner cylinder 2 and the outer cylinder 3 as much as possible. It is preferable to make the moving distance as long as possible. For example, when the dimensions of the inner cylinder 2, the outer cylinder 3 and the gap S are set as shown in Table 1 below, the amount of peanuts to be introduced into the gap S per unit time, the inner cylinder 2 and the outer cylinder By adjusting the relative rotational speed about the axis G with 3 (the rotational speed around the axis G of the inner cylinder 2 in the above embodiment), etc., the peanut is swirled 2 to 4 times in the gap S, The horizontal movement distance of peanuts can be made 1,382 mm to 2,764 mm. In this case, the difference between the width of the upper end of the gap S and the width of the lower end of the gap S (12 mm) divided by the horizontal movement distance of the peanut (1,382 mm to 2,764 mm) is 1 / The ground shell can be reliably peeled off because the gap S narrows very gently at a horizontal movement distance of as small as 115 to 1/230 and 1,382 mm to 2,764 mm.

The present invention is not limited to the above-described embodiment, and can be variously modified.
For example, the shell peeling machine of the present invention can be modified as shown in FIG. 12 and FIG. 13 (FIG. 12 is a front view showing a shell peeling machine 70 according to a modification of the present invention. FIG. 13 is this) It is a side view showing shell peeling machine 70 concerning a modification of the invention). In FIG. 12 and FIG. 13, for convenience of explanation, a portion which is actually hidden by another member is also appropriately shown by a solid line.

  In the above embodiment, the handle is used as the rotation means 5 for rotating the inner cylinder 2 around the axis G. However, in the shell peeling machine 70 of the modification shown in FIGS. 12 and 13, the inner cylinder 2 is around the axis G A motor 71 is provided as a rotating means for rotating the motor.

  Also in the shell peeling machine 70 shown in FIGS. 12 and 13, the outer cylinder 3 is fixed stationary, and the upper end of the inner cylinder 2 is closed by the top wall 9. The motor 71 is disposed below the inner cylinder 2 and includes a rotating shaft 72 and a motor main body 73. The rotation axis 72 extends vertically along the axis G, and its upper end is connected to the top wall 9 of the inner cylinder. The motor main body 73 rotates the rotating shaft 72 around the axis G, and the inner cylinder 2 also rotates around the axis G as the rotating shaft 72 rotates.

  In the shell peeling machine 70 shown in FIGS. 12 and 13, the rotation shaft 72 of the motor 71 doubles as a shaft (corresponding to the reference numeral 30 in FIG. 2) of the gap adjusting means 6. That is, in the shell peeling machine 70, the lower end of the rotating shaft 72 is supported by the table 31, and the width of the gap S can be reduced and enlarged by the lifting mechanism 32 raising and lowering the table 31.

  According to the shell peeling machine 70 described above, since the inner cylinder 2 can be rotated by the power of the motor, it is not necessary to take time and labor to rotate the inner cylinder 2 manually. Therefore, the labor required for shell peeling can be reduced. Similar to the shell peeling machine 1 shown in FIGS. 1 to 4, the shell peeling machine 70 shown in FIGS. 12 and 13 is also provided with a guide pipe 63 (FIG. 12) passing through the upper chute 60 and the lower chute 62. The rotary shaft 72 of the motor 71 is passed through the inside of the guide pipe 63.

  Moreover, although the example which puts peanuts in the clearance gap S using the hopper 4 was shown in said embodiment, the hopper 4 may be abbreviate | omitted and peanut water may be thrown in in the clearance gap S from the upper end of the clearance gap S. In this case, since the hopper 4 is omitted, the manufacturing cost of the shelling machine 1 can be reduced at a low cost. As described in the embodiment, if the hopper 4 is used, there is no need for a worker to stay near the shell peeling machine all the time in order to put peanuts in the gap S. Therefore, the time and effort can be reduced.

  In the above embodiment, the outer cylinder 3 is stationary fixed and the inner cylinder 2 is rotated about the axis G. Conversely, the inner cylinder 2 is stationary fixed and the outer cylinder 3 is stationary. May be rotated about the axis G. Alternatively, both the inner cylinder 2 and the outer cylinder 3 may be rotated about the axis G at different speeds, or the inner cylinder 2 may be rotated about the axis G and the inner cylinder 2 may be rotated about the axis G You may rotate it. Even in the above manner, since the inner cylinder 2 and the outer cylinder 3 can be relatively rotated about the axis G, the peanut is dropped in a spiral in the gap S, and the inner cylinder 2 and the outer cylinder 3 can be rotated. It is possible to peel off the peanut shell by friction with it. When the outer cylinder 3 is rotated about the axis G, for example, a protrusion extending around the axis G is formed at the lower end of the outer cylinder 3 and a groove extending around the axis G on the upper surface of the upper plate 7c of the carriage 7 Is formed to fit the projection of the outer cylinder 3 and the groove of the upper plate 7c. Then, a handle is attached to the outer surface of the outer cylinder 3, and the outer cylinder 3 is rotated about the axis G using the handle. Contrary to the above, a groove extending around the axis G is formed at the lower end of the outer cylinder 3, and a protrusion extending around the axis G is formed on the upper surface of the upper plate 7c. The protrusion may be fitted.

  Moreover, in the said embodiment, although the 1st hole 10 formed in the inner cylinder 2 was taken as the hole which penetrates the inner cylinder 2, the 1st hole 10 of the inner cylinder 2 is to the outer peripheral surface 2a of the inner cylinder 2. It may be a recess to be formed (that is, the first hole 10 of the inner cylinder 2 may not penetrate the wall of the inner cylinder 2).

  In the above embodiment, the first hole 10 formed in the inner cylinder 2 is long in the vertical direction, but the second hole 11 formed in the inner peripheral surface 3 a of the outer cylinder 3 is long in the vertical direction Both the first hole 10 and the second hole 11 may be vertically long.

  Moreover, although the outer cylinder 3 showed the example comprised from the inner-layer body 13 and the outer-layer body 14 in the said embodiment, the outer cylinder 3 may be comprised from a single member.

  In the above embodiment, an example is shown in which the outer diameter is larger as the inner cylinder 2 is lower and the inner diameter is larger as the outer cylinder 3 is lower, as shown in FIG. Like the shell peeling machine 80 of the modified example, the inner cylinder 2 may be a cylindrical shape having a larger outer diameter toward the upper side, and the outer cylinder 3 may be a cylindrical shape having a larger inner diameter toward the upper side (FIG. 14 illustrates For the sake of convenience, the part actually hidden by other members is also shown by a solid line as appropriate. Even in this case, if the inclination angle θc of the outer peripheral surface 2a of the inner cylinder 2 with respect to the horizontal surface is larger than the inclination angle θd of the inner peripheral surface 3a of the outer cylinder 3 with respect to the horizontal surface, the width of the gap S becomes smaller toward the lower side. . Therefore, various peanut shells different in size and shape can be peeled off.

  In the above embodiment, although the width of the gap S is adjusted by the gap adjusting means 6, the width of the gap S does not necessarily have to be adjustable. For example, like the shell peeling machine 80 shown in FIG. 14, the table 31 is fixed to the pillar 7 b of the carriage 7 via the horizontal member 7 f, and the lower end of the shaft 30 is supported by the table 31. However, the inner cylinder 2 (the top wall 9 of the inner cylinder 2) may be supported at a fixed position.
