Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper device for an oscillating member for a rotary brush, which is provided in a foreign substance removing device for removing foreign substances adhering to the shell surface of cultured shellfish.

[0002]

2. Description of the Related Art When culturing pearl oysters, it is necessary to remove minute shellfish such as barnacles and other foreign substances attached to or parasitic on the surface of the pearl oyster in order to promote its growth. The removal work is performed regularly.

In the case of edible cultured shellfish such as mussels and crows, foreign substances such as moss and algae adhering to the surface of the shell are removed when the shellfish is shipped with the shell to enhance its commercial value. Work is done.

Conventionally, this type of work has been performed manually by an operator, but, for example, an actual Kaihei 6-723.
According to Japanese Patent Laid-Open No. 54-54, a device for mechanically removing foreign matter on the surface of a pearl oyster (pearl oyster) is disclosed.

This device is provided with a total of four belts for sandwiching and conveying both left and right sides of the shellfish from above and below, and a plurality of rotating brushes arranged in pairs vertically along the shellfish transport path by these belts. (Rotating drum) and, with these rotating brushes, a configuration in which a large number of flexible arms, each having a hard grinding tip attached to the tip of the cylindrical main body, are planted in the radial direction, While the shell is being conveyed by the belt, the tip of each arm is hit against the surface of the shell by the rotation of the rotating brush to brush the surface.

According to this apparatus, foreign matter such as a barnacle attached to the surface of the pearl oyster can be efficiently removed by merely supplying the pearl oyster to the belt in sequence without requiring special skill of the operator. It becomes possible.

By the way, in this type of apparatus, the rotary brush is attached to the tip of the rocking member, and is biased by its own weight or a spring or the like in the direction of pressing it against the surface of the shellfish through the rocking member. It is conceivable that the rotating brush contacts the surface of the shell with the required strength.

In this case, the shell is clamped by the belt while pushing up against the rotating brush above and pushing down against the rotating brush below against the self-weight and the biasing force of the spring. In this state, it is carried into the brushing position, but in order to facilitate the carrying-in, the rocking of the rocking member or the rotary brush in the biasing direction is restricted at a predetermined position. It is necessary, and it is desired that the regulation position can be adjusted according to the thickness of the shellfish and the like.

Therefore, it is conceivable to provide a stopper device as shown in FIGS. 12 and 13 in order to regulate the swing of the swing member at a predetermined position.

That is, the stopper device 200 shown in FIG.
Is a bracket 2 fixed to the main body of the foreign matter removing device.
While fixing the nut 202 to 01, the nut 20
The bolt 203 is screwed onto the screw 2 and fixed by the lock nut 204, and the tip end thereof is brought into contact with the swing member 205, so that the swing of the rotating brush 206 due to its own weight or a biasing force such as a spring force can be performed at a predetermined position. By restricting and adjusting the tightening amount of the bolt 203 with respect to the nut 202, the rocking restricting position of the rocking member 205 or the rotary brush 206 is adjusted.

Further, a stopper device 210 shown in FIG.
Is the rotary shaft 2 in a direction perpendicular to the swing surface of the swing member 215.
11 is arranged and a cam 212 whose peripheral surface abuts on the swinging member 215 is attached to the rotating shaft 211.
The cam 212 allows the swinging member 215 to be driven by the biasing force.
In addition, the swinging of the rotary brush 216 is regulated, and the swinging regulation position is adjusted by rotating the cam 212 via the rotary shaft 211.

According to these, for example, FIGS.
When the rotating brushes 206 and 216 are arranged above, as shown in FIG. 3, by setting the swing restriction position to the upper side in the case of thick shellfish and to the lower side in the case of thin shellfish, respectively. Also in this case, the shellfish can be smoothly carried into the brushing position, and the surface of the shellfish can be brushed with appropriate strength.

[0013]

However, in the case of the above stopper device, the following problems can be considered.

First, in the case of swingably supporting the rotary brush, the swing member is disposed in the main body and is swingably attached to the vertical wall surface of the main body via the support shaft, and one end of the swing member is also provided. The rotary brush attached to the above will be configured to be arranged outside the main body by supporting it through a shaft that penetrates the vertical wall surface. However, in the case of the stopper device 200 shown in FIG. Since the swinging member 205 is arranged in the main body, the stopper device 200 is also arranged in the main body. Therefore, when adjusting the swinging restriction position, the work of loosening the lock nut 204 and adjusting the tightening amount of the bolt 203 has to be performed inside the main body, resulting in extremely poor workability.

Further, in the case of the stopper device 210 shown in FIG. 13, if the rotary shaft 211 of the cam 212 is projected to the outside from the vertical wall surface of the main body, the swing member 215 or the rotary brush 216 caused by the rotation of the cam 212. Can be performed outside the main body, and by using a lock nut 213 by providing a male screw on a portion of the rotary shaft 211 protruding outside the main body, It is possible to fix the cam 212, but this device 2
In the case of No. 10, when the position of the cam 212 is adjusted and then fixed by the lock nut 213, the cam 212 slightly rotates, or the load at the time of contact of the swing member 215 causes the cam 212 to rotate little by little. As a result, the rocking restricting position with respect to the rocking member 215 or the rotary brush 216 may gradually change. Further, even if the cam 212 is slightly rotated, the rocking restriction position changes relatively greatly, so that it becomes difficult to finely adjust the rocking restriction position.

The present invention addresses the above situation, and in an apparatus for removing foreign matter adhering to the surface of cultured shellfish such as pearl oysters, the rotating brush is supported by the swinging member, and the shellfish is used. By urging the rotating brush in a direction to press against the surface of the shell with appropriate strength, the rotation of the rotating brush due to the urging force is regulated at a predetermined position, and It is an object of the present invention to provide a stopper device that allows adjustment work from the outside of the main body and can perform delicate adjustment when the regulation position is adjustable, and that the adjustment position is reliably held.

[0017]

Means for Solving the Problems In order to solve the above problems, the present invention is characterized in that it is configured as follows.

That is, the stopper device of the rotary brush in the foreign matter removing device for cultured shellfish according to the present invention comprises upper and lower belts for sandwiching and transporting the cultured shellfish, and rotation for brushing the surface of the shellfish transported by the belt. A rotating brush is supported on one end of a swinging member swingably provided inside the vertical wall surface of the main body, and the rotating brush is pressed against the surface of the shell. In the urging apparatus for removing foreign matter from cultured shellfish, a bolt member that is provided so as to penetrate through the vertical wall surface and that advances and retreats in a direction orthogonal to the wall surface by a turning operation from the outside of the wall surface; The stopper member is attached to the tip end portion of the bolt member so as to project into the swinging surface, and restricts the swinging of the swinging member in the biasing direction at a predetermined position. Wherein the radial position of contact with the oscillating member by advancing and retracting by the rotation of the bets member is constituted by a cone changes.

[0019]

According to the above construction, the rotary brush is attached to one end of the swing member and is urged in the direction of being pressed against the surface of the shell, so that the rotary brush has an appropriate strength. In addition to brushing, the stopper device that regulates the swinging of the swinging member or the rotating brush in the biasing direction at a predetermined position does not cause the shell to push the brush more than necessary and push it down to the brushing position. It will be delivered smoothly.

In this case, when the bolt member of the stopper device is rotated, the stopper member composed of the bolt member and the conical body at the tip of the stopper member advances and retreats to come into contact with the swing member of the stopper member. By changing the radius of the position, the rocking restriction position of the rocking member is adjusted. Therefore, by properly setting the regulation position according to the thickness of the shellfish, the shellfish can be smoothly carried into the brushing position and can be brushed with appropriate strength.

a and 42b brush the left and right side portions on the upper surface side, then the central portion on the lower surface side by the front lower brush 41, and further, the second front upper brush 43.
Both side portions on the upper surface side are brushed again by the left and right portions 43a and 43b.

Next, the shell X is sandwiched between the front lower belts 11 and 12 and the front upper belt 13 at the center of the main body 2, and then the rear lower belt 14 and the pair of left and right rear upper belts 15, 16 and is passed between the belts 14 and 1 as shown in FIG.
By 5 and 16, it is held at the same three places on the central portion on the lower surface side and on both side portions on the upper surface side.

In this state, the shellfish X is further conveyed in the direction A, and first, the left and right parts 44 of the first rear lower brush 44 are formed.
a and 44b, the left and right sides on the lower surface side are brushed, then the central portion on the upper surface side is brushed by the rear upper brush 46, and the second rear lower brush 45 is further used.
Both sides on the lower surface side are brushed again by the left and right portions 45a and 45b. As a result, the shell X is brushed on the entire upper and lower surfaces thereof.

In this case, each of the rotating brushes 41 to 46 described above
As shown in FIGS. 6 and 7, is attached to swingable L-shaped arms 71.
7 ... 77 urges the lower brushes 41,44,45 upward through the L-shaped arms 71 ... 71, and the upper brushes 42,43,46 exert downward urging force by their own weight. Tuned and these brushes 41-46
And brushes 41 on the belts 11 to 16 on the opposite side
The belt receiving members 47 to 50 are arranged on the back side of the portions facing to each of the brushes 41 to 46 to receive the pressing force of the brushes 41 to 46. The tips of the hairs 62 ... 62 always come into contact with the upper and lower surfaces of the shell with substantially equal pressure.

Further, the bristle 62 of each rotary brush 41-46.
.. 62 includes a spring 62b and a head member 62c made of a hard material at the tip thereof, so that the head members 62c are rotated by the rotation of the brushes 41 to 46.
62c will hit the surface of the shell with moderate strength. As a result, foreign matter such as a barnacle firmly adhered to the surface of the shell is effectively removed without damaging the shell.

By the way, as described above, each rotating brush 41
Since the springs 77 ... 77 are urged in the direction in which they are pressed against the surface of the shellfish X by the springs 77 ... 77 or their own weight, when the shellfish X is carried into the brushing position by the rotary brushes 41-46, Rotating brush 41
~ 46 against the above-mentioned biasing force, the lower brushes 41, 4
4, 45 are pushed down, and the upper brushes 42, 43, 46 are pushed up.

In this case, the belts 11 to 1 of these rotary brushes 41 to 46 are denoted by reference numeral a in FIG.
When the initial rush amount into the transportation route 5 by 6 is large,
That is, when the initial positions of the upper brushes 42, 43 and 46 shown in the figure are too low and the initial positions of the lower brushes 41, 44 and 45 not shown are too high, a particularly thick shell In this case, it becomes difficult for the shellfish to push up or push down the rotary brushes 41 to 46 against the biasing force, and there is a possibility that the shellfish cannot be smoothly carried into the brushing position.

On the other hand, as shown by reference numeral B in FIG. 8, when the initial amount of protrusion of the rotating brushes 41 to 46 into the conveying path 5 is too small, that is, the upper brush 4 is inserted.
For 2,43,46 the initial position is too high,
If the initial positions of the lower brushes 41, 44, 45 are too low, especially in the case of a thin shell, the contact of the rotary brushes 41-46 on the shell may be weakened and brushing may not be sufficiently performed. is there.

Therefore, it is necessary to adjust the initial position of each of the rotary brushes 41 to 46, that is, the position for restricting the swing in the urging direction, and the adjustment work of the stopper device 78 shown in FIGS. Will be done.

Specifically, by loosening the lock nut 96 in the device 78 and rotating the bolt member 93 in a predetermined direction, the bolt member 93 and a stopper having a conical shape attached to the tip thereof are rotated. The member 95 is moved back and forth in the direction orthogonal to the vertical wall surface 2a of the main body, but this changes the radius of the contact position of the stopper member 95 with the L-shaped arm 71. Then, if the radius of the abutting position becomes smaller, the amount of rush of the rotary brushes 41 to 46 into the transport path 5 at the initial position becomes larger, as shown by reference numeral a in FIGS. If the radius becomes large, and the radius becomes large, the amount of rush of the rotary brushes 41 to 46 into the transport path 5 becomes small and the state is adjusted to be suitable for a thick shellfish, as indicated by reference numeral B. become.

This adjustment is performed by the lock nut 96 and the bolt member 93 exposed outside the vertical wall surface 2a of the main body.
The operation is performed on the head of the stopper member (see FIG. 1), and the amount of advance / retreat of the stopper member 95 or the amount of change in the swing restricting position with respect to the amount of rotation of the bolt member 93 is very small. Delicate adjustment is possible,
Further, even if the L-shaped arm 71 comes into contact with the stopper member 95, a force for rotating the bolt member 93 is not generated by the load thereof. Therefore, by tightening the lock nut 96 after completion of the adjustment, the adjustment position is changed to the next position. It will be held securely until the adjustment work of.

The above examples are suitable for removing foreign substances such as barnacles adhering to the surface of pearl oysters by crushing them. For edible cultured shellfish such as mussels and crows, It is also possible to remove foreign matter such as moss and algae attached to the shell surface. In this case, the rotary brushes 41'-46 'shown in FIG. 11 are used in place of the rotary brushes 41-46.

That is, these rotating brushes 41'-4
In 6 ', wire-like members 62c' ... 62c 'are attached to the tips of the springs 62b' ... 62b 'in each hair 62' ... 62 'instead of the head member made of a hard material. Wire-shaped member 62c '... 62
By c ', moss and algae attached to the surface of the shellfish are scraped off.

As described above, according to the present invention, foreign matter such as a barnacle attached to the surface of a pearl oyster, or foreign matter attached to the surface of a pearl oyster, is brushed by a rotating brush while sandwiching and transporting the oyster with upper and lower brushes. In a foreign matter removing device for the surface of cultured shellfish that removes foreign matter such as moss and algae attached to edible cultured shellfish such as mussels and crows, the rotating brush is attached to the tip of the swing member, and When the rotating brush brushes the surface of the shell with a proper strength by being urged in the direction of pressing against the surface of the shell, the oscillating member or the rotating brush oscillates in the urging direction. Since the shell is appropriately set according to the thickness of the shell, the shell can be smoothly carried into the brushing position without pushing the brush up or down more than necessary.

In particular, according to the present invention, the rocking restricting position of the rocking member can be adjusted by the stopper device from the outside of the main body, and good workability can be obtained. Adjustment is possible, and moreover,
The adjustment position will be securely held until the next adjustment work, so that the shellfish will always be smoothly brought into the brushing position and brushed with an appropriate strength. The foreign matter removal work will be performed well.
