An object of the present invention is to provide a small fish dismantling processing apparatus capable of efficiently removing small fish such as loach and the spine (middle bone) while leaving a tail fin.

(About claim 1)
The small fish dismantling processing device is fixed to a base on which a guide pillar is erected and fixed to a base, a set of bearings arranged on the guide pillar, a rotating shaft supported by the bearing, and a rotating shaft. Two circular blades, a bottom plate, a set of support plates, a set of holding plates, a set of pressing plates, and a movable body that has an outer round bar and an inner round bar by loosely fitting a compression coil spring, and a holding plate. It includes a spring, a pulley attached to a rotating shaft, an electric motor fixed to a base, a motor-side pulley attached to the drive shaft of the electric motor, and a belt spanned between the pulley and the motor-side pulley.

The base material is horizontally long and has a sliding groove formed on the upper surface in the longitudinal direction. In addition, guide pillars are erected from the left and right ends of the base.

A set of bearings is arranged facing the guide column at a position corresponding to the center of the board.
The rotating shaft is pivotally supported by the left and right bearings in a penetrating state (at least one of the left and right sides).
The two circular blades are fixed to the axis of rotation at a position facing the center of the base with a narrow blade spacing.

The bottom plate, which is a part of the movable body, has a plate vertical width substantially equal to the groove width of the sliding groove of the base material. This bottom plate has a concave groove formed in the longitudinal direction on the upper surface of the plate at a position where the two circular blades face each other.

A set of support plates that are part of a movable body is provided with communication holes with a cylindrical body at one end of the plate, the center of the plate, and the end of the plate, and is fixed axially on the bottom plate.

A set of holding plates that are a part of the movable body, which is arranged inward from the support plate, has an elastic plate inside the plate and forms a first circular recess on the outside of the plate at a position facing each communication hole. ing.

A set of pressing plates that are a part of the movable body forms a second circular recess inside the plate at a position facing the communication hole, and is arranged on the outer side of the support plate.

For the outer and inner round bars that are part of the movable body, the compression coil spring is loosely fitted into both round bars, and one end of the inner round bar is fitted into the first circular recess of the holding plate to form a pressing plate. One end of the outer round bar is fitted into the second circular recess.

The plurality of pressing plate springs have a fixed side fixed to the inside of the plate of the guide column and a movable side for pressing the pressing plate.
The pulley is attached to the rotating shaft outside the bearing.

The small fish dismantling processing apparatus according to claim 1 is used as follows.
A small fish such as a loach is dropped vertically from above between the holding plates of the movable body.
The movable body is slid from one side of the base toward the center along the sliding groove of the base.

Since the pressing plate of the movable body is pressed by the movable side of the holding plate spring whose fixed side is fixed inside the plate of the guide pillar, the pressing plate moves inward, the compression coil spring contracts, and the outer round bar moves inward. Transition to.

The holding plate is displaced inward by being pushed by the compressed compression coil spring, so that small fish are held by a set of holding plates.
When the small fish is slender, the outer round bar pushes the inner round bar inward, so that the holding plate is further pushed inward and displaced, and the small fish is held by the elastic plate of the holding plate.

Since the pulley is attached to the rotating shaft, the motor-side pulley is attached to the drive shaft of the electric motor, and the belt is hung between the motor-side pulley and the pulley, the circular blade is rotating.
When the movable body is slid from the center of the base to the other side along the sliding groove of the base, the small fish held by the elastic plates of the set of holding plates face the two circular blades and are small. Pinch the spine of the fish from both sides and tear it.

The small fish dismantling processing device has the following advantages.
The small fish dismantling processing device simply drops small fish such as loach vertically between the elastic plates of the holding plate of the movable body and slides the movable body along the sliding groove of the base, such as loach. You can easily remove the spine of a small fish from your body.

Since the small fish dismantling processing device has two circular blades fixed to the rotation axis with a narrow blade spacing, the body of the small fish can be cut open from both sides, and the dismantling processing time can be shortened.

In the small fish dismantling processing device, the pulley is attached to the rotating shaft, the motor side pulley is attached to the drive shaft of the electric motor, the belt is hung between the motor side pulley and the pulley, and the circular blade is rotated. The dismantling process can be performed continuously without any attachment.

Since it is not necessary to rotate the circular blade manually, the physical strength of the worker is not consumed, and the dismantling time per animal can be shortened, which is efficient.
If the structure is such that the drive shaft of the electric motor is directly connected to the rotating shaft, rattling occurs and the dismantling work is hindered.

Since a concave groove is formed in the longitudinal direction on the upper surface of the bottom plate where the two circular blades face, a part of the small fish (ventral side) falls into the concave groove, so the two circular blades are on the lower part of the small fish. It did not reach, and after dismantling, a part of the small fish (ventral side) could be left, and two pieces were wholesaled. In addition, the tail fin remains.

Since the small fish are sold in two pieces, the small fish doubles in size when opened and the tail fin remains, so it looks good.

The small fish dismantling processing device adopts an outer round bar and an inner round bar loosely fitted with a compression coil spring, one end of the inner round bar is fitted into the first circular recess of the holding plate, and one end of the outer round bar is fitted. Since it is fitted into the second circular recess of the pressing plate, it is possible to take a long stroke for the pressing plate to be displaced inward.
Therefore, regardless of whether the small fish to be dismantled is thick or slender, it is sandwiched by the elastic plate of the holding plate with an appropriate strength, and it is not necessary to adjust the holding force.

(Claim 2)
The two circular blades fixed to the rotating shaft at a position facing the center of the substrate have a diameter of 50 mm to 70 mm, a blade thickness of 0.3 mm, and a blade spacing of 2 mm to 3 mm.
Further, the concave groove formed on the upper surface of the plate at the position where the two circular blades face each other has a width of 5 mm to 7 mm and a depth of 1.5 mm to 2.5 mm.

The two circular blades have a blade spacing of 0.25 mm to 0.35 mm and a blade spacing of 2 mm to 3 mm.
A set of holding plates holds small fish from both sides, but the thinness of the circular blade is 0.25 mm to 0.35 mm, which prevents the outer edge of the circular blade from opening outward. can. If the blade thickness is less than 0.25 mm, it is too thin and causes insufficient strength, and if the blade thickness exceeds 0.35 mm, it is too thick and it becomes difficult to prevent the phenomenon that the outer edge portion opens outward.

Since the blade spacing is as narrow as 2 mm to 3 mm, it can be disassembled to the very limit of the spine. If the blade spacing is less than 2 mm, it is too narrow and the spine is crushed, and if it exceeds 3 mm, the fish meat portion is reduced.

The concave groove formed on the upper surface of the plate at the position where the two circular blades face each other has a width of 5 mm to 7 mm and a depth of 1.5 mm to 2.5 mm.
For this reason, the lower part of the small fish just fits into the concave groove, and the two circular blades do not reach the lower part of the small fish, leaving a part (ventral side) of the small fish after dismantling. , You can surely make two wholesales. In addition, the tail fin can be surely left.
If the width of the concave groove is less than 5 mm, it becomes difficult for the lower portion of the small fish to fit, and if it exceeds 7 mm, a gap is formed and the small fish tends to tilt.

The two circular blades 21 and 21 (diameter 60 mm) are made of tungsten steel having a blade thickness of 0.3 mm, and a narrow blade spacing of 2.5 mm is opened by a spacer on the rotating shaft 2 at a position facing the center of the base 11. Is fixed.

The movable body 3 includes a rectangular bottom plate 31, support plates 32 and 32 fixed to the upper surface of the bottom plate, holding plates 33 and 33 located on the inner side of the support plates 32 and 32, and outside of the support plates 32 and 32. It is composed of pressing plates 34, 34 located on the side, an outer round bar 35a into which a compression coil spring b is loosely fitted, and an inner round bar 35b.

The bottom plate 31 (length 96 mm × width 180 mm) has a plate length width (96 mm) substantially equal to the groove width of the sliding groove 11, and has a concave groove 311 (recessed groove 311) on the upper surface of the plate at a position where the two circular blades 21 and 21 face. (Width 6 mm x depth 2 mm) is formed in the longitudinal direction.

The set of support plates 32, 32 fixed in the axial direction are provided with communication holes 322 with a cylindrical body 321 at one end, the center of the plate, and the end of the plate, respectively.

The set of holding plates 33, 33 is provided with an elastic plate g inside the plate, and a first circular recess 331 to which the inner end of the inner round bar 35b is fitted is formed on the outside of the plate at a position facing each communication hole 322. There is.
The set of pressing plates 34, 34 forms a second circular recess 341 inside the plate at a position facing each communication hole 322.

The inner round bar 35b has one end 351 fitted into the first circular recess 331 of the holding plates 33, 33, and the outer round bar 35a has one end 352 fitted into the second circular recess 341, and the pressing plate 34, A compression coil spring b is loosely fitted to both round bars between 34 and the support plates 33 and 33.

The plurality of pressing plate springs 14 have a fixed side 141 screw-fixed to a plurality of positions inside the guide pillars 12 and 12, and a curved movable side 142 that presses the pressing plates 34 and 34 from the outside.

The small fish dismantling processing device A of Example 1 is used as follows.
Since the pulley 22 is attached to the rotary shaft 2, the motor side pulley 42 is attached to the drive shaft 41 of the electric motor 4, and the belt 43 is hung between the motor side pulley 42 and the pulley 22, the electric motor 4 is energized. Then, the circular blades 21 and 21 are in a rotating state.

The loach 5 is vertically dropped from above between the holding plates 33 and 33 of the movable body 3.
The movable body 3 is slid from one side of the base 1 (lower part in the drawing) toward the center along the sliding groove 111 of the base 1 (see FIG. 4).

Since the pressing plates 34 and 34 of the movable body 3 are pressed by the movable sides 142 of the pressing plate spring 14 having the fixed sides 141 fixed inside the plates of the guide pillars 12 and 12, the compression coil springs b contract and the pressing plates 34 and 34. And the outer round bar 35a shifts inward (see FIG. 5).
Since the compression coil spring b contracts, the holding plates 33 and 33 are displaced inward, so that the loach 5 is sandwiched by the two holding plates 33 and 33.

When the movable body 3 is slid along the sliding groove 111 of the base 1 from the center of the base 1 to the other side, the loach 5 sandwiched by the two holding plates 33, 33 has two circular blades. Facing 21 and 21, the spine of loach 5 is pinched from both sides and torn.

The small fish dismantling processing apparatus A of Example 1 has the following advantages.
The small fish dismantling processing device A simply drops the loach 5 vertically from above between the holding plates 33 and 33 of the movable body 3 and slides the movable body 3 along the sliding groove 11 of the base 1. The spine of loach 5 can be easily removed from the body.

The pulley 22 is attached to the rotary shaft 2, the motor side pulley 42 is attached to the drive shaft 41 of the electric motor 4, the belt 43 is hung between the motor side pulley 42 and the pulley 22, and the circular blades 21 and 21 are rotated. Therefore, the loach 5 can be continuously disassembled without rattling.

Furthermore, since the two pieces 21 and 21 having a thickness of 0.3 mm are fixed to the rotating shaft 2 with a narrow blade interval of 2.5 mm, the body of the loach 5 can be cut open from both sides and disassembled. Time can be shortened.

The two circular blades 21 and 21 have a blade spacing of 0.3 mm and a blade spacing of 2.5 mm. The loach 5 is sandwiched from both sides by a set of holding plates 33, 33, but since the blade thickness of the circular blades 21 and 21 is as thin as 0.3 mm, the outer edges of the circular blades 21 and 21 open outward. It is possible to prevent the phenomenon of being squeezed, and at the same time, the strength is maintained. In addition, since the blade spacing is as narrow as 2.5 mm, it can be disassembled to the very limit of the spine.

Since it is not necessary to rotate the circular blades 21 and 21 manually, the physical strength of the worker is not consumed, and the dismantling time of the loach 5 and one animal can be shortened.
If the drive shaft 41 of the electric motor 4 is directly connected to the rotary shaft 2, rattling will occur and the dismantling work will be hindered.

Since the concave groove 311 is formed in the longitudinal direction on the upper surface of the bottom plate 31 at the position where the two circular blades 21 and 21 face each other, the ventral side of the loach 5 falls into the concave groove 311.
Therefore, the two circular blades 21 and 21 do not reach the ventral side of the loach 5, and after the dismantling treatment, the ventral side of the loach 5 can be left, and the two blades are wholesaled. In addition, the tail fin of loach 5 remains.
Since the loach 5 is sold in two pieces, the loach 5 doubles in size when opened and the tail fin remains, so it looks good.

The small fish dismantling processing device A employs an outer round bar 35a and an inner round bar 35b in which a compression coil spring b is loosely fitted, and one end 351 of the inner round bar 35b is fitted into the first circular recess 331 of the holding plate 33. Since one end 352 of the outer round bar 35a is fitted into the second circular recess 341 of the pressing plate 33, a long stroke for the pressing plate 33 to be displaced inward can be taken.
Therefore, regardless of whether the small fish to be disassembled is thick or slender, it is sandwiched by the elastic plate g of the sandwiching plate 33 with an appropriate strength, and it is not necessary to adjust the sandwiching force.
