[0022]

According to the invention of claim 1, a flat belt, a V
An endless conveyor is formed by an endless chain in which the elastic endless belt, which is one of a belt and a round belt, is fitted to the outside, and is used by meshing with a spur gear and a sprocket gear corresponding to the endless chain.

When an appropriate tensile force is applied to the endless conveyor to tension it, the tensile force is endured by the endless chain forming a part of the endless conveyor, and the elastic endless belt is excessively stretched. Does not give distortion. Further, since the portion that contacts the gear is an endless chain, there is almost no slippage between them, there is no variation in the conveying speed, and the conveying force is large. Since the surface of the endless carrier is composed of the elastic endless belt described above, when sandwiching the cultured shellfish, it moderately elastically deforms to increase the contact area with the cultured shellfish, and by the force on the cultured shellfish received by the cleaning work. However, the cultured shellfish are transported without being removed from the endless conveyor. When the elastic endless belt is worn out, only this is removed from the endless chain and replaced with a new elastic endless belt.

According to the invention of claim 2, claim 1
In addition to the operation of the invention described above, a detachable fitting structure is provided at every several chain elements in the lengthwise direction of the endless chain, among the element plates arranged in the transverse direction, on the top surfaces of both outer side element plates, Since the elastic endless belt is provided with a retaining stopper having a height shorter than the thickness of the elastic endless belt, and the elastic endless belt is fitted between the plurality of pairs of retaining stoppers, the endless conveyor is flat. When detached from the gear or sprocket gear, the elastic endless belt easily disengages beyond the disengagement protrusion and replacement with a new one requires no special tool.

While the endless conveyor is running, a certain amount of pulling force also acts on this elastic endless belt.
It does not come off. Further, since the height of the slip-out preventing protrusion is lower than the thickness of the elastic endless belt, when the cultured shellfish is sandwiched by the endless carrier, the slip-out preventing protrusion does not hit the cultured shellfish and sandwiches the cultured shellfish only by the elastic endless belt portion. It will not damage the cultured shellfish.

According to the invention of claim 3, in addition to the operation of claim 2, since the endless chain is composed of a silent chain, meshing with the spur gear is sure and the drive gear is transferred to the endless conveyor. The power transmission of is reliable, and the sandwiched aquaculture shells are transported reliably. Also, since it is a silent chain, the meshing noise with the spur gear is small.

According to the invention of claim 4, in addition to the operation of the invention of claims 1 and 2, the endless chain is constituted by a roller chain, so that the meshing with the sprocket gear is sure, Power transmission from the drive gear to the endless conveyor is reliable, and the sandwiched aquaculture shells are transported reliably.

In the invention according to claim 5, since the endless conveyor of left-right paired up and down type is equipped,
These endless conveyors can be carried by sandwiching two positions on both ends of the cultured shellfish. At this time, at least one endless conveyor of one endless conveyor is driven by a silent chain that constitutes the endless carrier. The spur gear of this endless conveyor is significantly wider than the width of the silent chain of the sandwich type endless conveyor, and the endless conveyor is movable and fixed in the width direction of the gear, so it depends on the size of the cultured shellfish to be transported. An upper and lower pair of endless conveyors in which the endless belt and the silent chain are combined are moved in the gear direction to adjust the gap between the left and right holding type endless conveyors.

At least one of the one-sided endless conveyors
Since the part of the book that holds the cultured shellfish is an elastic endless belt, it follows the shape of the sandwiched cultured shellfish.The elastic endless belt is elastically deformed and dented. It is not damaged and has a large supporting force, and in combination with the meshing of the silent chain and the gear described above, it has a large force for transporting cultured shellfish. Further, the operation of the endless conveyor including the combination of the individual silent chains and the elastic endless belt is the same as the operation of the invention according to claims 1 and 3.

According to the sixth aspect of the invention, the pair of left and right sandwiching type endless conveyors are both a combination of a silent chain and an elastic endless belt. strong. Also, the crushed shells and the like are hardly crushed into smaller pieces by the silent chain and the gear portion, and the transporting power is hardly reduced or slipping is hardly caused. The other operation is the same as that of the invention of claim 5.

According to the seventh aspect of the present invention, since the chain of the endless conveyor is a roller chain, the chain is a washing device for aquaculture shells, which is composed of a combination of the chain and the elastic endless belt. Because it is a good thing, the manufacturing cost is cheap,

According to the invention of claim 7, the roller chain and the sprocket gear are moved in the axial direction of the sprocket gear while meshing with each other, and the interval between the pair of left and right endless conveyors is adjusted. In addition, substantially the same operation as in claim 5 is performed.

In the invention of claim 8, since the pair of left and right endless conveyors of the pinching type endless conveyor is composed of the combination of the roller chain and the elastic endless belt, there is no slip between the sprocket gear and the power. Strong transmission power. Further, the crushed shells and the like are not finely crushed by the roller chain and the gear portion, so that the carrying force does not decrease and the slip does not occur. The other operation is the same as that of the invention of claim 6.

In the invention described in claim 9, the operation described in claim 5, claim 6, claim 7 or claim 8 is achieved in the same manner, and at least two sets of the endless conveyor are arranged in front and rear in the transport direction. Since the connected portions are lapped or very close to each other, the cultured shellfish to be conveyed are smoothly transferred one by one on two or more endless conveyors.

Each time the trains are successively transferred, different parts of the cultured shellfish are sandwiched, and the parts that were sandwiched by the upstream endless conveyor are not sandwiched by the next endless conveyor, and the deposits remain without being ground. The place where it is present is tapped with a grinding member to grind the attached matter.

According to a tenth aspect of the present invention, among the rotary drums of the fifth to seventh or eighth aspects of the present invention, at least one of the rotary drums has a tilted flexible arm. Since the angle is inclined 5 ° to 40 ° in the circumferential direction with respect to the diametrical direction of the drum, the operation of the invention according to claim 5 to claim 7 or claim 8 is naturally achieved and the flexibility is increased. When the rotary drum is rotated in the direction in which the base of the arm precedes the tip, the flexible arm is prone to fall over, and there is no danger of it becoming like a stretch rod. It will not fall down easily and the grinding effect will be improved. Use it properly according to the adhesion strength of the deposit.

No matter which direction the rotating drum rotates, these flexible arms are subjected to centrifugal force and curved in the middle of the arms. Although it receives the force in the axial direction of the flexible arm, the flexible arm always bends or curves from the middle, and the grinding member slides along the surface of the aquaculture shell, It is almost impossible for the grinding member to break through the aquaculture shell because the flexible arm becomes a tension rod.

In the eleventh aspect of the present invention, the flexible or foldable arm to which each of the grinding members is attached may have at least two joints having an axis parallel to the rotation axis of the drum. Since at least one replaceable drum as a foldable arm is equipped, the drum with the foldable arm is attached to the washing device according to the strength of the cultured shellfish to be treated, and conventional washing is performed. Operate in the same way as the device.

In this way, the joint of each foldable arm and the grinding member stand up at a right angle from the peripheral surface of the drum due to the centrifugal force caused by the rotation of the drum in each foldable arm, and each grinding member cultivates the shellfish. The resistance of the arm that bends due to the resistance of the surface bends backward from the joint based on the direction of rotation, but centrifugal force always acts on them, so the bending angle changes from the joint while the tip is ground. The member passes through the peripheral surface of the cultured shellfish while repeating intermittent contact.

Since the axis of the joint of this joint is parallel to the axis of the drum, the foldable arm hardly falls in the axial direction of the drum. Therefore, without contacting the endless conveyor holding the cultured shellfish violently. The endless conveyor, the grinding member and the foldable arm are less damaged by these collisions.

In the twelfth aspect of the present invention, the weight of the grinding member at the tip of each foldable arm is 0.3 g to 3 g.
Since it is 0 gram, each foldability is sufficiently raised at the normal rotation speed of the rotary drum, and in each weight, it acts to grind the deposits adhering to the cultured shellfish.

When the weight of the grinding member is 0.2 g or less, the mass is insufficient to give an impact enough to grind the adhering substance, and when the grind member is 30 g or more, each foldable arm is sufficiently provided. It cannot be erected, and if the rotation speed of the rotating drum is set high enough to erected, the impact force is too strong and there is a risk of destroying the cultured shellfish to be treated.

【Example】

Embodiment 1 It is an embodiment including the inventions of claims 1, 2 and 3 and is shown in FIGS. 1 to 4 and 7.

Usually, aquaculture shellfish (such as Akoya shellfish, scallop shell and the like are simply referred to as shellfish in the following description of the embodiments) is held and conveyed horizontally. A pair of endless conveyors is provided on the left and right, and the endless conveyor C of the endless conveyor C1 used in this aquaculture shell cleaning device is configured as follows. In these drawings, 10 is an endless chain, and two teeth 12 are provided inside each chain element 11 and are connected so that the teeth 12 of the chain elements successively arranged in the length direction are overlapped one by one. It is a silent chain 10a.

Each of the chain elements 11 is connected in the width direction by overlapping several chain elements adjacent to each other in the length direction. The element plates 11a of the chain elements on both even-numbered sides of the chain element 11 are higher in height than the other element plates 11, and the retaining projections 13 of the elastic endless belt 15 are formed on the top portion.

In the illustrated example, the pitch of the detachment preventing projections 13 is provided on every fourth chain element 11, but
It may be every 2nd or every 6th, but if the pitch is too long,
The elastic endless belt 15 is easily detached from the endless chain 10. The above-mentioned endless silent chain 10 is operated by engaging the teeth 12 of the endless silent chain 10 with the spur gear 20.

The elastic endless belt 15 is usually a flat belt 15 in which elastic synthetic resin or elastic synthetic rubber and reinforcing cloth are integrated.
a, the width of which is fitted between the pair of left and right retaining projections 13 so as to slightly cover the upper surface of the retaining projection 13. Therefore, the thickness t is the height h of the retaining projection 13. It is slightly thicker.

Alternatively, as shown by the chain line in FIG. 2, there is a case where the removal preventing projections 13 are completely covered so that they are not exposed to the outside.

The elastic endless belt 15 described above is included in this embodiment in addition to the flat belt 15a shown in FIG. 2, or the V belt 15b or the round belt 15c as shown in FIG. 3 or 4. . A chain-type and belt-type composite endless carrier C is constructed as described above.

Embodiment 2 This is an embodiment including the invention described in claims 1, 2 and 4, and is shown in FIGS. 5 and 6.

An endless chain 10 is different from the first embodiment.
The joint shaft portion 16 connecting each chain element 11 is not a silent chain but meshes with a sprocket gear described later, and the roller 18 is rotatable on each small shaft 17 of the joint shaft portion 16. Respectively, and is usually called a roller chain 10b. That is, it can be easily understood by thinking of a normal bicycle chain.

In addition, the same reference numerals as in the first embodiment indicate the same constituent members or the same constituent parts. Similar to the first embodiment, the roller chain 10b is also provided with the retaining projections 13 at the same pitch.

In this specification, the block chain in which the rollers 18 are not fitted to the respective small shafts 17 and the sprocket gear 21 is simply meshed with the small shafts 17 is also included in the concept of the roller chain.

Also in the second embodiment, the flat belt 1 is used.
The V belt 15b and the round belt 15c may be used instead of 5a (see FIGS. 2 to 4).

Operation of Embodiment 1 Chain element 1 constituting the endless chain 10
The teeth 12 of No. 1 are meshed with the spur gear 20,
It is used by being strained by 0 (see FIG. 7). In this way, the elastic endless belt 15 fitted on this surface is also tensioned. Normally, this chain-and-belt composite type endless carrier C is provided in two pairs of upper, lower, left and right, and horizontally conveys shells while holding them at two places.

In this case, the teeth 12 of the silent chain 11a and the spur gear 20 are successively meshed with each other to form the silent chain 1
The elastic endless belt 15 fitted on the outer side of the la 1 also accurately travels at the speed of the pitch circle of the gear 20. The shell that is held between the upper and lower endless carriers C has a stopper 13
It is held by the elastic endless belt 15 and conveyed without hitting.

In the case of using the elastic endless belt 15a shown by the chain line in FIG. 2, since the slip-off preventing projection 13 is completely covered by the elastic endless belt 15, the slip-off preventing projection does not hit the shellfish being conveyed. Absent.

Since the elastic endless belt 15 that holds the shellfish has elasticity, it is slightly recessed along the surface of the shellfish, and it holds the shellfish stably with a wider surface and does not crush the shellfish. When the elastic endless belt 15 is the V-belt 15b, it is possible to wash the shellfish even up to the holding portion of the shellfish.

When the elastic endless belt 15 is worn or deteriorated due to long-term use due to contact with a shell or a grinding member, the elastic endless belt 15 is replaced with a new elastic endless belt 15 or the elastic endless belt is changed according to the kind of shell. In the case of replacing with a different shape of the uneven shape 19 on the surface of 15, the elastic endless belt 15 is removed from the silent chain 10a and replaced with the desired elastic endless belt 15.

Operation of Embodiment 2 The same operation as in Embodiment 1 is performed, except that the endless chain is the roller chain 10b, and the sprocket gear 2
1, the sprocket gear 21 meshes with the roller 18 of the joint shaft portion 16 which joins each chain element 11, and the roller chain 10b.
The composite type endless carrier C including the elastic endless belt 15 and the elastic endless belt 15 is accurately conveyed at the speed of the pitch circle of the sprocket gear 21.

Embodiment 3 This is an embodiment including the invention described in claims 5 and 6, and is shown in FIGS. 7, 8 and 13 to 16. In addition, at least one endless conveyor C1 of the upper, lower, left and right pairs used in this embodiment uses the endless conveyor C of the first embodiment. In this embodiment, as a precondition, three sets of adhering matter removing devices B are provided symmetrically in the vertical direction in the illustrated example at the conveying portions of the above-mentioned two pairs of the upper, lower, left and right endless conveyors C1 (see FIG. 7).

The adhering substances removing device B is a conveying part of the endless conveyor C1, and a rotary drum 50 is attached to a rotary drive shaft 53 which is perpendicular to the conveying direction. Flexible or foldable arms 51 are provided in a radial pattern, and grinding members 52 are fixed to the tips of the flexible or foldable arms 51, respectively.
When the rotary drum 50 is rotated, the surface of the shellfish being conveyed by the endless conveyor C1 is removed by the grinding member 52.
It is equipped so that it can be tapped in sequence. The lengths of the flexible or foldable arms 51 described above are generally the same, but there are also cases in which arms having slightly different lengths are mixed.

In the third embodiment, of the two pairs of left and right endless conveyors C1, the pair of upper and lower conveyors on one side does not move in the axial direction of the spur gear 20 or the pulley but operates at that location. That is, the width of the spur gear 20a or pulley and the silent chain 11 or the endless V belt 1
It matches the width of 5b.

In FIG. 8, the spur gear 20b on the left side is provided with a remarkably wide width of about 2 to 20 times the width of the silent chain 11, and this spur gear 20b is provided with the rotary gear shaft 2 thereof.
It is fixed to No. 2 with a key 23, for example. The endless carrier C, which is a combination of the silent chain 11 and the elastic endless belt 15, is provided so as to be movable and fixed in the axial direction of the spur gear 20b fixed to the rotary gear shaft 22. The chain guide 31 of the conveyor moving means 30 provided in the machine frame 40 of the aquaculture shell cleaning device can move and fix it.

This chain guide 31 is screwed onto a feed screw 32 parallel to the rotary gear shaft 22.
By rotating 2 around its axis, the chain guide 31 is moved in the direction of the rotary gear shaft 22, so that the silent chain 11 can be moved and fixed at any position of the spur gear 20 by the chain guide 31. . In the illustrated example, the pair of upper and lower chain guides 31 can be collectively moved as a lump (joined by a chain line in the drawing).

Also in this embodiment, the elastic endless belt 15 is the flat belt 15a and the V belt 15b as in the first embodiment.
Alternatively, the case of the round belt 15c is also included in this embodiment. In the above-mentioned embodiment, there may be at least one of the four upper, lower, left and right endless conveyors C formed by the combination of the silent chain 11 and the elastic endless belt 15. However, all four endless conveyors C have this structure. It is an example of the described invention.

Operation of Embodiment 3 In this embodiment, a composite type endless carrier C composed of a silent chain 11 and an elastic endless belt 15 is used by the conveyor moving means 30 according to the size and type of shellfish to be treated. , The width of the spur gear 20 is moved, and the space between the pair of upper and lower endless conveyors on the other side is adjusted.

That is, when the shellfish is a small shellfish, a small shellfish shell, or even a large shellfish, it is desired to wash both sides of the shellfish, the feed screw 32 is rotated around its axis to move the chain guide. 31 is used in close proximity to the endless conveyors on the other side, and the space between these left and right endless conveyors is narrowed for use.

When holding both sides of a large shell,
By rotating the feed screw 32, the chain guide 31 is separated from the endless conveyor on the other side, and the endless conveyor guided by the chain guide 31 is kept in mesh with the silent chain 11 and the spur gear 20. It is moved in the axial direction of 20, and the pair of left and right endless conveyors are widened and set for use.

As the drive mechanism for moving the chain guide 31 described above, the means using the feed screw 32 is shown, but instead of this, a lever or ratchet that can be moved and fixed in stages, or the feed screw 32 and the lever can be fixed. Those that operate using a power source are also included in this embodiment.

When the above-mentioned endless carrier C is used for the left, right, upper and lower four endless conveyors of this apparatus, all of these endless conveyors carry shellfish under substantially the same conditions so that shellfish Even if the attachment removing device receives a conveyance resistance in the middle of the conveyance, the shellfish hardly rotate, and the conveyance is ensured without coming off the endless conveyor.

Thus, when the shellfish being conveyed by the endless conveyor C1 passes through the positions of the three sets of deposit removing devices B, the surface of the shellfish is sequentially beaten by the grinding members 52 to deposit. Parts are removed.

Embodiment 4 This is an embodiment including the invention described in claims 7 and 8 and is shown in FIGS. 7 and 9. The same reference numerals as those in the third embodiment indicate the same constituent members or constituent parts, and perform the same or similar operations. The prerequisites of this embodiment are the same as in the third embodiment.

The difference is that the endless carrier C of at least one endless conveyor among the four endless conveyors on the left, right, top and bottom uses the second embodiment. In the illustrated example, all of the endless conveyors C of the endless conveyors are those of the second embodiment. Therefore, the gear meshing with the roller chain 10b is not the spur gear but the sprocket gear 21.

Thus, a total of four sprocket gears 21, one pair of front and rear and two pairs of upper and lower front and rear, which mesh with the pair of upper and lower endless carriers C on one side, are provided with respect to the rotary gear shaft 22 with respect to the sliding key 23a. The sprocket gear 2 is fixed in the rotating direction and is movable in the axial direction.
The gear shift adjusting means 35 is slidably fixed to the rotary shaft 22 in the same direction all at once. For example, at one end of the boss 24 of all the sprocket gears 21 supported by the slide key 23a, the donut disc 3 is provided.
6 is extended and fixed, and a feed screw 32 parallel to the rotary gear shaft 22 is screwed onto a part of a moving member 38 having a pawl 37 slidably engaged with the outer peripheral portion of the donut disk 25. Is rotated around the axis to make it possible to move and fix the four sprocket gears 21 all at once in the axial direction,
The conveyor on the other side can be moved closer to and away from it.
The gear moving means 35 may be a mechanism of another mechanism like the conveyor moving means 30 of the third embodiment, and is not limited to the above example.

Operation of Embodiment 4 In Embodiment 4, since the roller chain 10b and the sprocket gear 21 are engaged with each other by the joint shaft portion 16 which sequentially connects the chain elements 11, the Embodiment 3
Unlike the above, when the roller chain 10b is moved in the direction of the sprocket shaft 22, both the roller chain 10b and the sprocket gear 21 are also moved in the axial direction to adjust the distance from the endless conveyor on the other side. The adjustment is as described by rotating the lead screw 32 about its axis either manually or by a motor, either forward or reverse. Other actions are similar to those of the third embodiment.

Embodiment 5 This is an embodiment including the invention of claim 10 and is shown in FIGS. 10 and 12. In this embodiment, two sets of conveyor devices Q and R, in each of which a pair of upper and lower endless conveyors are provided on the left and right, are sequentially provided in series in the conveying direction,
The pair of left and right endless conveyors of the conveyor device Q and the conveyor device R have mutually different intervals (see FIG. 12).
), The rotary gear shaft 22 at the carry-out end of the upstream conveyor device Q and the rotary gear shaft 22 at the upstream end of the downstream conveyor device R are common gear shafts, and are endless conveyors of the conveyor device. Cs are wrapped around each other (see Figure 12). Endless carrier C used in this embodiment
Are the same as those in the first or second embodiment, or the upstream side is the first embodiment, and the downstream side is the second embodiment, or vice versa. Although not shown, the upper and lower endless conveyors on one side can adjust the distance between the left and right conveyors by the structure of the third or fourth embodiment (see FIG. 12).

Embodiment 6 The invention according to claim 10 is included and is shown in FIG. The same reference numerals as in the fifth embodiment indicate the same components. The difference is that the upstream and downstream conveyor devices Q and R are provided so as to be very close to each other (smaller than the size of the shell). In addition, only the lower endless conveyor is wrapped in the same manner as in Example 5, and the upper endless conveyor is closely approached in the same manner as in Embodiment 6, which is also included in the embodiment of the present invention. .

Actions of Embodiments 5 and 6 The shellfish supplied to the conveyor device Q on the upstream side is first clamped at two left and right positions by a pair of upper and lower conveyors, and then transferred to the rotary drum 50 while being conveyed in the downstream direction. With each grinding member 52 at the tip of a large number of flexible or flexible arms 51, the surface of the shell that is not sandwiched by the pair of left and right endless conveyors is sequentially tapped to remove the deposits on this surface.
Next, the downstream conveyor device R clamps the upstream conveyor device R at a position different from that clamped by the upstream conveyor device Q, and the downstream conveyor device R is equipped with deposits remaining in this part. It is removed by the attached matter removing device B. In this case, since the endless carriers C of the upstream and downstream conveyor devices R are wrapped or extremely close to each other, the shellfish to be processed is successively transferred by successively transferring the conveyor devices Q and R which are connected in the upstream and downstream directions.

In the apparatus of the fifth embodiment, since the endless conveyors on the upstream and downstream sides are wrapped, the shellfish transfer is smooth. In the apparatus of Example 6, the endless conveyors on the upstream and downstream sides are extremely close to each other (about half the size of the shellfish), and therefore, there is almost no difference from the case where the wrapping is performed, and the transfer is smooth. The other actions are the same as those in the third or fourth embodiment.

Embodiment 7 The invention according to claim 11 is included and is shown in FIG. Examples of the conveyor device include Examples 3, 4, and 5.
Alternatively, one of 6 is used. The rotating drum 50 of the deposit removing device D for removing deposits such as parasitic shellfish, other parasites, and seaweed on the shell surface is usually made of a coil spring or a flexible material such as synthetic rubber, synthetic plastic or a metal wire bundle. Through flexible arm 51a, which is a type of foldable arm 51
Are provided upright in the radial direction, and each end of these flexible arms 51a has a grinding member 52 for grinding the surface of the shell.
Is stuck. The rotary drum 50 is supported by a rotary drive shaft 53 that is perpendicular to the conveying direction of the endless conveyor and is horizontal, and is located between the left and right conveyors, inside and outside the left and right conveyors C1, and in a position where it does not hit the endless conveyor C. It is provided. Particularly, the flexible arm 51a is the rotary drum 50.
The angle α is 5 ° to 40 °, preferably 10 ° to 20 °, in the circumferential direction with respect to the radial direction.

Therefore, depending on the direction of rotation of the rotary drum 50, each of the flexible arms 51a is inclined to the front or the rear. Operation of Embodiment 7 In the apparatus of this embodiment, when the drum 50 of the adhered matter removing device B of this embodiment is rotated in the middle of conveyance by the conveyor device, each flexible arm 51a has flexibility. , 5 ° to 40 ° at each root
Even if the flexible arms 5 are attached so as to be inclined in the circumferential direction,
Centrifugal force causes 1a to be substantially in the radial direction of the drum from the middle thereof. That is, each flexible arm 51a draws a gentle curve in the middle portion of the arm 51 and is in a curved state. Therefore, the flexible member 51a is curved in the circumferential direction by hitting the shell member 52 at the tip of each end, but even if a force is applied in the direction of compressing the length of the flexible arm 51a, The middle of the flexible arm 51a is already formed of a curved portion. The bending degree increases from this portion only, and the flexible arm 51a does not bend in any direction like a tension rod, and the grinding member at the tip end. There is almost no action to break through the shell.

Also, by selecting the rotation direction of the rotary drum forward or backward, there is a slight difference in the flexibility of the flexible arm 51a. By utilizing this, the flexible arm 51a can be used in accordance with the attachment situation of shellfish deposits. To do. The rotary drum 50 in which the flexible arm 51a is inclined is included in this embodiment as long as at least one of the cleaning devices is provided. Normally, a pair of upper and lower is made one set, and even an attachment part is included in this embodiment.

Embodiment 8 The invention according to claim 11 is included and is shown in FIGS. 14 to 17. The difference from the seventh embodiment is that the arm attached to the rotary drum 50 is not flexible and is a foldable arm 51b having at least two joints 54. In the structure shown in FIGS. The number is three, including the root mounting portion, and is the same as in a normal bicycle chain, and the direction of the axis of each joint 54 is parallel to the rotary drive shaft 52 of the rotary drum 50. The number of joints of the chain that constitutes the foldable arm 51b is 2 to 20, which is technically possible, but is preferably 3 to 5. Reference numeral 56 denotes a leaf spring which is erected from the outer peripheral surface of the rotary drum 50 on the back side of the foldable arm 51b.

Operation of Embodiment 8 Together with the drive rotary shaft of this rotary drum, each foldable arm 51b.
Are erected in the radial direction of the rotary drum by centrifugal force, and when the foldable arm 51b hits the shellfish, the resistance causes the foldable arm 51b to temporarily bend later than an arbitrary joint 54, and The part collides with a leaf spring 56 provided upright on the rear surface, and again rises due to centrifugal force, hits the shell again, and the shell is conveyed by an endless conveyor,
It passes through this rotary drum 50 part. This foldable arm 51
By adhering the grinding member 52 at the tip of b to the shell, deposits on the shell surface are removed.

In what is shown in FIGS. 14 and 15,
One foldable arm 51b is independently attached to the arm attachment 57 fixed to the rotation drum 50, and attached to the rotation drum 50 by a pin 58 parallel to the axis of the rotation drum 50. A part of the above is the leaf spring 56 described above. This pin 58 is also a kind of the shaft of the joint.

Example 9 In each of FIGS. 16 and 17, each foldable arm 51b
14 has the same structure as that shown in FIGS.
The difference is that the lower ends of the three foldable arms 51b are attached to a common arm attachment 57b by a common long pin 58b. Therefore, the leaf spring 56 is also integrated with the arm attachment 57b, and is independently erected along the back surface of each foldable arm 51b. The operation of the ninth embodiment is almost the same as that of the eighth embodiment.

[Embodiment 10] An embodiment including the invention according to claim 12 is shown in FIGS. 18 to 20. This invention is the same as the sixth embodiment.
The grinding member 52 is attached to the tip of the flexible arm 51 or the foldable arm 51b shown in FIGS. This grinding member 52
Conventionally, a hexagonal bolt, which is a typical element of a normal machine, has been used, but the one shown in FIG. 18 uses a piano wire or steel wire having a diameter of 0.3 mm to 1 mm and a length of 10 mm to 40 mm.
mm, bundled in a diameter of about 3 mm to 8 mm, or a 3 mm to 6 mm square bar shown in FIG.
Alternatively, as shown in FIG. 20, a round bar having a diameter of 3 to 6 mm or the like and a weight of 0.3 g to 20 g were used. The base of the grinding member 52 and the foldable arm 51b are pivotally attached so as to be bendable (see FIGS. 14 to 16). When the flexible arm 51 is a coil spring, the grinding member 52 is directly fixed by brazing or the bolt fixed to the grinding member 52 is screwed and fixed to the tip of the coil spring (see FIG. 18).

Operation of Embodiment 10 As long as it has a size and weight similar to those of Embodiment 10, each flexible arm 51a or foldable arm 5 on the peripheral surface of the rotary drum 50 is used.
When attached to the tip of 1b and rotating the rotary drum 50 at a normal rotation speed, each grinding member 52 obtains sufficient momentum, and when this collides with the shellfish being transported, the grinding member 52 adheres to the shellfish as described above. There is enough momentum to crush the parasitic shellfish such as Fuji jars, and these are crushed and removed. When the grinding member 52 has a wire bundle as shown in FIG. 18, the individual wires are bent to some extent, and the impact is softened, which is suitable when the shell to be treated is fragile.

According to the first aspect of the invention, since the elastic endless belt is fitted on the outside of the endless chain, the tensile force applied to the endless conveyor is received by the chain and the elastic endless belt is over-pulled. It does not give force, it does not stretch out without fatigue and when it comes into contact with the cultured shellfish that is transported, this part elastically deforms and does not damage the cultured shellfish, and the contact area with the cultured shellfish is large, so support is reliable Becomes Since the inner chain is conveyed by meshing with spur gears or sprocket gears, the conveying speed accurately follows the rotation of the gears and the conveying force is strong, and the conveying speed of the endless conveyor and the conveying force are uniform. Accurately transport the aquaculture that is used.

Further, the inner endless chain is strong and durable, and the outer elastic endless belt can be replaced with a new one when it is worn.

According to the invention of claim 2, claim 1
In addition to the effects of the invention described above, the detachable structure of the endless chain and the elastic endless belt is, as described above, the number of chain elements arranged in the lengthwise direction Of these, the endless chain and the elastic endless belt are easy to put on and take off because they are fitted between the detent protrusions provided on the tops of the element plates on both sides. The belt will not come off beyond the detent projections.

Further, since the height of the retaining stopper is lower than the thickness of the elastic endless belt, the retaining stopper does not hit the cultured shell during the process of transporting the cultured shell to be treated.

According to the invention of claim 3, claim 1
Alternatively, in addition to the effect of the invention as set forth in claim 2, since the endless chain is composed of the silent chain, the meshing is strong, the driving force of the gear is completely transmitted to the endless chain, and the operation is quiet.

According to the invention of claim 4, claim 1
Alternatively, in addition to the effect of the invention described in claim 2, since the endless chain is a roller chain and the gear meshing with the chain is a sprocket gear, the conveyor device itself is lighter than the one using the silent chain, and the operation is reduced. It consumes less power and has a simple roller chain structure that makes cleaning easier.

In the invention according to claim 5, as described above, at least one endless transporter equipped with the same has the structure according to claim 1, claim 2, claim 3 or claim 4. Therefore, in the endless conveyor using the endless chain and the elastic endless belt, in addition to the effects of the above-mentioned claim 1, claim 2, claim 3 or claim 4, While transporting the cultured shellfish to be treated, a large number of flexible or foldable arms are provided on the peripheral surface of the rotary drum, and the tip of this arm is equipped with a grinding member to operate the deposit removing device. However, when the surface of the cultured shellfish is tapped by the grinding member to remove the deposits on the surface of the cultured shellfish, the elastic endless belt is supported by the endless chain, and therefore, even against the impact due to the tapping, it is large. It may bend or vibrate. Without any, also conveyed reliably farming shellfish to the conveying resistance received during the above-mentioned deposit removal.

Even if the grinding member comes into contact with the endless chain portion of the endless carrier, this portion is much stronger than the endless belt, and can withstand long-term use, and the inner surface of the elastic endless belt can be ground by the grinding member. Since there is no beating, the service life of the elastic endless belt is extended.

According to a sixth aspect of the present invention, all the endless conveyors of the endless conveyor are elastic endless belts fitted to an endless silent chain, and one of the left and right holding endless conveyors has a rotary gear shaft. It is characterized in that it is equipped so as to be movable and fixed with respect to the gear that meshes with the endless conveyor. Therefore, all endless conveyors have the effects of claim 1, claim 3, claim 3 or claim 4. The left and right endless conveyors are transported without any change in the left and right speeds of the cultured shellfish to be processed, and one of the endless conveyors on both sides is as described above. For the spur gear in the direction of the rotary gear,
Since the silent chain can move while meshing, if the size of the cultured shellfish to be treated differs from lot to lot, the distance between the pair of left and right endless conveyors can be adjusted in advance to the size of the cultured shellfish to be treated. With this device, it is possible to transport and wash aquaculture shells of various sizes. In addition, the effect of the invention according to claim 5 is obtained.

According to the invention described in claim 7, it is configured and operates as described above and has the same effect as that of claim 5, but the chain is not a silent chain but a chain that meshes with a sprocket gear. Therefore, it is undeniable that some noise is generated at the time of engagement, but the structure is simple and cleaning is easy.

The invention described in claim 8 has the same effect as that of the invention described in claim 6.

According to the ninth aspect of the present invention, since it is configured and acts as described above, the aquaculture shells conveyed by this device and the downstream part of the endless conveyor of the conveyor device are upstream and downstream. Since the position of being caught by the endless conveyor of the side conveyor device is different, the deposits on all parts of the aquaculture shell can be removed by the deposit removing device.

Further, since the endless conveyors of the upstream conveyor device are provided so as to be slightly wrapped or very close to each other, the cultured shellfish to be treated has the effect of successively transferring over the endless conveyors for transport.

According to the tenth aspect of the present invention, it is attached to the rotary drum of the deposit removing device used in the fifth, sixth, seventh, eighth or ninth aspect.
Since each flexible arm is inclined at 5 ° to 40 ° in the circumferential direction, when the rotary drum rotates, the portion of the flexible arm near the tip end faces the radius of the rotary drum due to centrifugal force. Since the flexible arm turns into a curved state on the way and rotates with the drum, the grinding member at the tip of each flexible arm hits the cultured shellfish,
Even if force is applied in the axial direction of the flexible arm, each flexible arm bends further, so that the flexible arm becomes like a stake and the grinding member attaches a shell of aquaculture shell to be processed. The risk of breaking is extremely rare.

Since each flexible arm is inclined in the same direction, there is a difference in easiness of bending of each flexible arm by rotating the rotation direction forward and reverse half-turns. Depending on the situation, the rotation direction can be appropriately selected and used.

In the eleventh aspect of the present invention, since each arm as described above is not flexible and is foldable, the above-described operation is performed and the tip of the foldable arm is ground. When the member hits the surface of the shell, the foldable arm bends from its joint and does not give an excessive impact to the shell.

Since the rotary drum provided with the foldable arm is at least one of the rotary drums that can be converted to the cleaning device, it is appropriately selected according to the strength of the shell of the cultured shellfish. The effect that it can be replaced and used is produced.

According to the twelfth aspect of the present invention, the structure of the grinding member is as described above, the weight is 0.2 to 30 grams, and one mass is formed. When a proper amount of momentum is given and it collides with the surface of the cultured shellfish, it crushes the Fuji jar etc. adhering to it and grinds other parasites, seaweed, etc., and has the effect of hardly damaging the cultured shellfish . When the grinding member is lighter than 0.2 grams, the momentum is small and the effect of crushing grinding and Fuji jars is small, and the heavy one that exceeds 30 grams has too much momentum due to the rotation of the drum and the aquaculture to be treated. The shellfish are so shocked that they may destroy or kill the cultured shellfish itself.
