(c) Problems to be solved by the invention However, in the conventional cleaning device, the scallops placed on the conveyor belt in a hanging state were conveyed by the moving force of the conveyor belt. However, if there is no forced moving force and the rotational force of the cleaning brush is strong, conveyance may be hindered.

Therefore, it is not possible to increase the frictional force of the cleaning brush, and in order to provide the cleaning brush itself with a conveying force, the rotation direction of the cleaning brush is reversed, and the cleaning brush is rotated in the same direction on the top and bottom surfaces of the shellfish. It was rotating.

This caused the problem that the cleaning power could not be increased.

The present invention provides forcibly moving claws 7 on the conveyance chain 8, and locks them to the scallops hanging from the ears.
By forcibly taking the culture string and scallops A into the machine in an orderly manner, eliminating the burden on the operator, and forcibly transporting the scallops, there is no need to assist the transport with the cleaning brush. In order to provide more powerful cleaning power, the cleaning brush is rotated in the same rotation direction to push back the scallops.

(d) Means for solving the problems The purpose of the present invention is as described above, and next, the configuration for achieving the purpose will be explained.

An upper guide 3 and a lower guide 4 that sandwich the shellfish are arranged above and below the passage path of the cultured shellfish in the ear-hanging state, and one of the guides 3 and 4 is made vertically movable, and furthermore, the cultured shellfish in the ear-hanging state is locked. The conveyance chain 8 and forced movement claw 7 that are forcibly conveyed are moved on the upper surface of the lower guide 4, and the upper cleaning brush 1 is placed on the upper side of the upper guide 3.
A lower cleaning brush 2 is arranged below a lower guide 4, and both brushes 1 and 2 are rotated in the same rotation direction.

The figure is a rear sectional view showing the arrangement of the upper guide and the lower guy.

The overall structure of the cultured shellfish cleaning device of the present invention will be explained based on the drawings of FIGS. 1 to 5.

Cultivated shellfish cleaning equipment is generally operated on aquaculture rafts floating in seawater bays or inlets, and sometimes the shellfish are transported ashore by boat before being cleaned.

For this reason, the cultured shellfish cleaning device is often moved, and a pair of wheels 13 and a stand 33 are arranged at the bottom so that it can be towed by a trailer or the like.
When moving, the stand 33 is left floating, and when working, it is erected to support and fix the entire device.

The cleaning device has a box-cylindrical shape with left and right side plates 17, 18, a bottom plate, and a top plate. On the top plate are an engine E, a conveyance reducer M, and a cleaning brush reducer N.
is located.

Further, a cleaning pump P that sends pressurized water to the upper nozzle 5 and the lower nozzle 6 is arranged on the top plate.

The engine E drives the cleaning brushes 1 and 2, the conveying chain 8, and the cleaning pump P.

A hoisting device 9 is disposed at the front end of the cleaning device to sequentially hoist up the shellfish being cultured in an ear-hung state.

In this example, scallop A was used as the cultured shellfish.
Examples are shown below. Scallops A are suspended in the sea from an aquaculture raft with their ears connected with a culture string. During aquaculture, seaweed, barnacles, etc. attach to the surface of the scallop A's shell, which hinders the growth of the scallop A. To remove these, scallop A is pulled out of the aquaculture raft several times a year. I need to wash it.

In conventional cultured shellfish cleaning equipment, it was necessary for the operator to set the position of the cultured shellfish, so that the cultured shellfish, which had been suspended by the culture string, were bitten into the equipment in an orderly manner.

In the present invention, the scallop A suspended by the ear is hooked onto the culture string by the forced movement claw 7 provided on the conveyance chain 8, and the scallop A is fed into the cleaning device, and the movement speed of the forced movement claw 7 is Accordingly, the hoisting device 9 is rotated to take in the scallops A hanging by the ears on the culture string in an orderly manner and transport them to the cleaning section.

As shown in Figures 3 and 4, the cleaning brushes include four upper cleaning brushes 1a, 1b, 1c, 1d, and 4 upper cleaning brushes.
It is composed of lower cleaning brushes 2a, 2b, 2c, and 2d, and the upper cleaning brushes 1a, 1
b, 1c, 1d and lower cleaning brushes 2a, 2b, 2
Scallop A at the middle position between the top and bottom where c and 2d touch
It is configured so that it can pass through.

In addition, the rotation directions of the upper cleaning brushes 1a, 1b, 1c, and 1d and the lower cleaning brushes 2a, 2b, 2c, and 2d were conventionally almost always rotated in the opposite direction.
In the present invention, the rotation direction of the upper and lower cleaning brushes is the same, and the difference in peripheral speed between the two cleaning brushes is increased to improve the cleaning effect on the surface of the scallop A.

That is, the upper cleaning brushes 1a, 1b, 1c, and 1d are rotated in the direction in which the scallops A are fed, and the lower cleaning brushes 2a, 2b, 2c, and 2d are rotated in the direction in which the scallops A are returned.

However, since the conveyance chain 8 and forced movement claw 7 forcefully convey the scallops A, the conveyance of the scallops A is not hindered even if the lower cleaning brush 2 rotates in the opposite direction.

Since the scallop A has an approximately circular shape with ears and is flat, it is necessary to transport it while guiding it by sandwiching it between the top and bottom. Therefore, a bar-shaped lower guide 4 with a width that prevents the scallop A from falling is used. and upper guide 3
are arranged.

Then, the scallop A passes through while being sandwiched between the upper guide 3 and the lower guide 4. Further, since the sizes of the scallops A are different, the interval between the upper guide 3 and the lower guide 4 cannot be kept constant, and the upper guide 3 is supported so as to be movable up and down. The lower guide 4 is fixed. In addition, the upper guide 3 and the lower guide 4 are configured so that their widths gradually become narrower so that they are rolled up from the winding device 9 and arranged in an orderly line between the upper guide 3 and the lower guide 4. be.

The conveyor chain 8 is driven by the sprocket 19 on the sprocket shaft 22, and
It is wound between the sprockets 20 on top of the sprocket 3. The upper nozzle 5 has upper cleaning brushes 1a, 1b,
The lower cleaning brushes 6 are installed in the left and right direction in each gap between 1c and 1d, and are arranged as 5a, 5b, and 5c. Similarly, the lower cleaning brushes 6 are installed in each gap between lower cleaning brushes 2a, 2b, 2c, and 2d. , 6c are arranged.

The upper cleaning brushes 1a, 1b, 1c, 1d are supported by four cleaning brush shafts 10, and the left and right sides of the cleaning brush shafts 10 are supported by side plates 17, 18.
It is supported by bearings on bearing adjusting plates 15 and 12 arranged above. Similarly, the cleaning brush shafts 11 of the lower cleaning brushes 2a, 2b, 2c, and 2d are also adjustable on the left and right side plates 17, 18, and supported by bearings on bearing adjustment plates 14, 16. And bearing adjustment plates 15, 12 and 1
By adjusting 4 and 16 up and down with adjustment bolts, the gap between the cleaning brushes can be adjusted and the degree of cleaning can be changed. It is also possible to cope with the attenuation of the cleaning effect due to wear of the cleaning brush.

As shown in FIG. 2, the engine E drives the conveyance reducer M and the cleaning brush reducer N, and the conveyor reducer M connects the sprocket shaft 22 with a chain.
It drives the upper sprocket 21.
Also, from the cleaning brush reducer N, the cleaning brush shaft 1
By driving the sprocket on each cleaning brush shaft 10, 11, the sprocket on each cleaning brush shaft 10, 1

FIG. 6 is a plan view of the upper guide 3, FIG. 7 is a side view, FIG. 8 is a plan view of the lower guide 4, and FIG.
The figures are also side views, Figure 10 is a rear sectional view of the cleaning brush in working condition, Figure 11 is a rear sectional view of the cleaning brush disassembled to replace it, and Figure 12 is a rear sectional view of the cleaning brush when it is disassembled to replace it. , is a side view of a state in which the upper cleaning brush 1 is adjusted up and down.

Upper guide 3 as shown in FIGS. 6 and 7
The front part of the scallop A is curved and becomes high, and gradually becomes lower, allowing the scallop A, which comes in a standing position, to lie down and assume a normal posture. For this reason, the front entrance part is not constructed in the shape of a bar, but is constructed in the shape of a plate. Furthermore, since the lower guide 4 is fixed, the upper guide 3 needs to be movable up and down depending on the size of the scallop A, and the upper and lower pins 29 at the front end and the upper and lower pins 28 at the rear end are required to move between the side plates 17 and 18.
It is configured to be movable up and down within the elongated hole. The intervals between the bars of the upper guide 3 are set to such an extent that the scallops A will not fall.

In FIGS. 8 and 9, the shape of the lower guide 4 is illustrated, and the lower guide 4 is also not a crosspiece in order to guide the scallop A to a normal posture in the vicinity of the entrance at the front end. It is made up of iron plates. Then, the point where the washing water from the upper nozzle 5 and the lower nozzle 6 reach is constructed as a crosspiece.

As shown in FIG. 10, in this configuration, the driving parts of the cleaning brushes 1 and 2 and the forced movement claw 7 are concentrated on the right side plate 18, so that the bearing adjusting plate 15 on the left side plate 17 side can be easily removed. It is structured as follows.

With this configuration, when the cleaning brush is worn out, the cleaning brush can be removed by removing the bearing adjustment plate 15 and pulling out the brush shaft 10a at the same time. The dog clutch device 35 is then removed, and only the cleaning brush can be removed.

Conversely, insert a new cleaning brush into the brush shaft 10a, and connect the dog clutch device 35 part to the drive side shaft 1.
Reassembly can be easily performed by combining the parts on 0b. That is, there is no need to remove the brush shaft 10a from the bearing adjustment plate 15, and the drive side shaft 1
0b does not need to be removed from the side plate 18, and the power is transmitted through the dog clutch device 35, so it can be easily removed by simply removing the bearing adjustment plate 15.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, since the cultured shellfish are forcibly transferred by the transport chain 8 and forced movement claw 7, even if the upper cleaning brush 1 and the lower cleaning brush 2 are rotated in the same direction and the surface of the cultured shellfish is strongly cleaned, It will not make the situation worse.

Second, upper cleaning brush 1 and lower cleaning brush 2.
By rotating the two in the same rotational direction, the top and bottom of the cultured shellfish can be rubbed in different directions to clean them, thereby increasing the ability to remove deposits.

Thirdly, by using brushes as the upper and lower cleaning bodies, there is less damage to cultured shellfish compared to the case of conventional pressure rollers.
