  The means for squeezing the citrus fruit using the squeezing belt is a configuration in which the citrus fruit is squeezed without being peeled and is easy to handle. However, in order to squeeze the citrus fruit as it is, the bitterness and miscellaneous taste of the skin may be mixed, or the residue may be mixed into the squeezed fruit juice because the squeezing pressure is too strong. On the other hand, when the squeezing pressure is weakened, the squeezing efficiency decreases and the squeezing amount decreases. Moreover, in the means shown in Patent Document 1, it is difficult to adjust the distance between a pair of squeezing belts that are arranged to face each other so that the gradual distance is narrowed. Even in the means shown in Patent Document 2, the squeeze efficiency cannot be increased only by selecting the friction coefficient of the member that compresses the fruit.

  In other words, in the conventional squeezing device using a squeezing belt, adjustment of the squeezing pressure is complicated and difficult, so skill and technology are required for proper adjustment, and adjustment in a short time is difficult. is there. In addition, it is difficult for an operator who uses the squeezing device to adjust the squeezing pressure by himself, because in practice it is necessary to use it without making adjustments or without making adjustments, There is also a problem in the stabilization of the quality of the squeezed juice due to the occurrence of poor squeezing due to poor adjustment. Therefore, the present condition is that the apparatus which uses a squeezing belt and squeezes the fragrant high quality citrus fruit juice efficiently has not been proposed yet.

  On the other hand, in the means for cutting the peel of the squeezed citrus fruit shown in Patent Document 3, a large amount of residue is mixed in the peel, the quality is not stable, and the cut thickness of the peel cannot be adjusted. Therefore, in order to cut high quality peels, there are still many places that still rely on manual work. Moreover, it is a device separate from the squeeze device, and could not be operated in conjunction with the squeeze process.

  Then, this invention solves the problem which the above-mentioned conventional squeezing means has, and makes it possible to adjust the optimal squeezed state easily and accurately according to the type and size of the citrus fruit. It is an object of the present invention to provide a citrus fruit squeezing device that can improve squeezing efficiency and squeezing quality and can also cut the peel in conjunction with the squeezing process.

  In this embodiment, the upper rods 12a and 12b and the lower rods 13a and 13b are connected by three adjustment shafts 22 in total, that is, three each. Since hexagonal bolts with male screws 22b with a pitch of 1.5 mm are used as the adjustment shafts 22 on the peripheral surface of the tip, by rotating one sprocket 24 once, the six adjustment shafts 22 are simultaneously moved in the same direction. This means that the mounting frames 15a and 15b can be moved closer to or away from each other by 1.5 mm in one rotation. Thereby, according to the kind and size of the citrus fruit to squeeze, it becomes possible to adjust immediately the space | interval between squeezing belts 10a and 10b to the optimal squeezed state. Moreover, fine adjustment is easy, and no skill or technical knowledge is required.

  In the present embodiment, the mounting frame 15b is configured to move toward or away from the mounting frame 15a. However, both the mounting frame 15a and the mounting frame 15b are provided with the adjustment shaft 22 having a turnbuckle structure. It is also possible to adopt a configuration in which the frame moves, and if necessary, the distance between the mounting frame 15a and the mounting frame 15b may be adjusted.

  Next, the installation structure of the drive rollers 8a and 8b will be described. 9 is a perspective view of the main part showing the discharge port 6 side, FIG. 10 is a cross-sectional view of the main part, FIG. 11 is a partially enlarged cross-sectional view, and FIGS. 12, 13 and 14 are plan views of the main part. In the figure, reference numeral 31 denotes a rectangular installation plate having a predetermined area, which is fixed to the upper surface of the end of the frame 3 on the discharge port 6 side by a plurality of bolts (not shown). A pair of drive motors 33a and 33b are fixed by a plurality of bolts (not shown) on a pair of adjustment plates 32a and 32b installed at predetermined intervals on the upper surface of the installation plate 31, and the drive shafts 34a and 34b are moved vertically. And is fixed as a central axis through the drive rollers 8a and 8b. Therefore, the drive rollers 8a and 8b are rotationally driven by the drive motors 33a and 33b, and the squeezing belts 10a and 10b spanned between the drive rollers 8a and 8b and the driven rollers 9a and 9b are rotated endlessly. At the same time, the squeeze roller 11 rotates in contact with the squeeze belts 10a, 10b.

  Caps 35a and 35b are covered with the lower ends of the drive shafts 34a and 34b, and the coupling shaft 36 is slidably inserted into the caps 35a and 35b, so that the drive rollers 8a and 8b are mutually connected. It is connected. The adjustment plates 32a and 32b are respectively provided with long holes 43a and 43b having a substantially square shape in plan view at predetermined positions on both ends on the discharge port 6 side, and through the long holes 43a and 43b, respectively. It is fixed to the installation plate 31 by a pair of bolts 37 located at both ends in opposite directions.

  A pair of bearings 38a and 38b are erected at the tip of the adjusting plates 32a and 32b on the discharge port 6 side, and a drive roller adjusting shaft 39 is pivotally supported by the bearings 38a and 38b. The bearings 38a and 38b are provided with insertion holes in which female screws are engraved. On the other hand, male screws in opposite directions are engraved on the periphery of the drive roller adjusting shaft 39. The male screw on the periphery of the adjustment shaft 39 is screwed into the female screw in the insertion hole of the bearings 38a and 38b. An intermediate portion of the drive roller adjustment shaft 39 is supported by a bracket 40 erected on the installation plate 31, and an operation ring 41 such as a hexagon nut is provided on the outer peripheral surface of the drive roller adjustment shaft 39 positioned between the brackets 40. Is protruding.

  By adopting the above configuration, it is possible to adjust the distance between the drive rollers 8a and 8b. FIG. 12 shows the positional relationship and posture of the adjusting plates 32a and 32b when the distance between the driving rollers 8a and 8b is wide, and FIG. First, from the state shown in FIG. 12, the bolt 37 that fixes the adjustment plates 32a and 32b to the installation plate 31 is loosened, and the operation ring 41 is rotated using a handle such as a spanner to rotate the drive roller adjustment shaft 39. By rotating, the adjustment plates 32a and 32b connected by the drive roller adjustment shaft 39 rotate in directions that are relatively close to or away from each other about the rotation fulcrums 42a and 42b. At this time, since the bolt 37 is loosened and is loosely screwed to the installation plate 31, the adjustment plates 32a and 32b are movable within the range of the elongated holes 43a and 43b having a substantially square shape in plan view. The positions of the long holes 43a and 43b with respect to the bolt 37 will change.

While loosely fitting in 31a, it is screwed into the adjusting plates 32a and 32b. That is, since the inner diameter of the rotation fulcrum hole 31a is larger than the diameter of the bolt 44, the adjustment plates 32a and 32b with which the bolt 44 is screwed are slid on the installation plate 31 using the bolt 44 as the rotation fulcrums 42a and 42b. Can move. Therefore, the adjustment plates 32a and 32b rotate around the rotation fulcrums 42a and 42b, and the drive rollers 8a and 8b come close to or separate from each other.

  The state shown in FIG. 14 is a close state, and the adjustment is completed by fixing the adjustment plates 32a and 32b to the installation plate 31 again with the bolts 37 in a state adjusted to a predetermined interval. That is, the state shown in FIG. 14 shows a state in which the driving rollers 8a and 8b are close to the horizontal axis by an angle α. Therefore, the distance between the drive rollers 8a and 8b can be adjusted uniformly in millimeters by male screws in opposite directions engraved on the portions of the drive roller adjustment shaft 39 that are supported by the bearings 38a and 38b. is there. By adjusting the distance between the drive rollers 8a and 8b in this way, the thickness of the peel of the citrus fruit after squeezing changes, so that the thickness of the peel after squeezing is adjusted to be thicker and thinner depending on the purpose of use. can do.

  Next, the installation structure of the driven rollers 9a and 9b will be described. 15 and 17 are main part perspective views showing the inlet 5 side, FIG. 16 is a side view of the main part, and FIGS. 18 and 19 are plan views of the main part. In the figure, reference numeral 46 denotes an installation plate, which is fixed to the upper surface of the end portion of the frame 3 on the insertion port 5 side by a plurality of bolts (not shown). A pair of bearings 47a and 47b are installed on the upper surface of the installation plate 46 at predetermined intervals, and a pair of driven shafts 48a and 48b inserted and fixed in the center of the driven rollers 9a and 9b are eccentric to the bearings 47a and 47b. It is pivotally supported at the position.

  Caps 49a and 49b are covered with the lower ends of the driven shafts 48a and 48b, and the caps 49a and 49b and the caps 35a and 35b of the drive shafts 34a and 34b are connected by connecting rods 50a and 50b. The bearings 47a and 47b that support the driven shafts 48a and 48b are installed with a plurality of bolts 52 (four in the illustrated example) 52 through long holes 51 (see FIGS. 18 and 19) drilled at predetermined positions. 46 is fixed.

  By adopting the above configuration, the distance between the driven rollers 9a and 9b can be adjusted. FIG. 18 shows a case where the distance between the driven rollers 9a and 9b is wide, and FIG. 19 shows a case where the interval is small. First, when the bolt 52 is removed from the state shown in FIG. 18 and the bearings 47a and 47b are rotated, the bearings 47a and 47b and the driven shafts 48a and 48b are in an eccentric relationship, so that the driven shafts 48a and 48b come close to or separate from each other. As a result, the driven rollers 9a and 9b also approach or separate from each other. By adjusting the distance between the driven rollers 9a and 9b, the size of the citrus fruit to be squeezed can be accommodated.

  The state shown in FIG. 19 is a close state, and the adjustment is completed by fixing the bearings 47a and 47b to the installation plate 46 with the bolts 52 in a state adjusted to a predetermined interval. Further, the bearings 47a and 47b can be rotated 180 degrees and rearranged. Therefore, depending on the type and size of the citrus fruit to be squeezed together with the adjustment of the distance between the mounting frames 15a and 15b and the adjustment of the distance between the driving rollers 8a and 8b and the driven rollers 9a and 9b, the purpose of use is further increased. In order to realize the squeezed state corresponding to the squeezed state, the interval between the squeezing belts 10a and 10b and other squeezing environment and squeezing conditions can be adjusted to the optimum squeezed state.

  Further, the ends of the mounting frames 15a and 15b in the direction of the insertion port 5 face each other in an expanded state toward the direction of the insertion port 5, and form a space portion having a substantially isosceles triangular shape in plan view. An anti-projection plate 53 having a substantially isosceles triangle shape in plan view is installed so as to cover the upper opening of the space portion, and a road surface plate having a substantially isosceles triangle shape in plan view in the lower space portion. 54 is installed. In the vicinity of the apex of the road surface plate 54, a cutting blade 55 is formed for forming a cut in the citrus fruit to be squeezed, and a cut is formed in the citrus fruit to be squeezed with the road surface plate 54 and the cutting blade 55. A cutting device is formed.

  Next, the structure of the disc body 56 as a protruding piece for scraping and dropping the fruit juice adhering to the squeezed citrus fruit passing between the squeezing belts 10a and 10b will be described. 20 is a perspective view of the main part showing the attachment state of the disk body 56, FIG. 21 is a partially enlarged view of the attachment part, and FIGS. Support members 59a and 59b are installed on brackets 57a and 57b fixed to the outer surfaces of the lower collars 13a and 13b between the mounting frames 15a and 15b facing each other in parallel, and coil springs or the like are installed on the support members 59a and 59b. The lower ends of the elastic bodies 58a and 58b are mounted. Then, support members 64a and 64b are mounted on the upper ends of the elastic bodies 58a and 58b at a certain distance from the support members 59a and 59b, and the support members 64a and 64b are opposite to the elastic bodies 58a and 58b. Convex portions 65a and 65b are respectively provided at the end portions, and both end portions of the through shaft 60 are fixed to the convex portions 65a and 65b so as not to rotate.

  And the disk body 56 is mounted | worn with the outer peripheral part of this penetration shaft 60 as a protrusion piece, The disk body 56 is squeezed by the squeeze roller 11, and the lower part of the citrus fruit conveyed between the squeezing belts 10a and 10b is carried out.
