Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a cleaning device for lifting cultured shellfish, such as scallops, from the sea during the cultivation and rearing process, and cleaning and removing deposits attached to the surface of the shellfish. This invention relates to a straightening machine that corrects the posture of supplied ear-hung cultured shellfish.

(Conventional technology) The methods used today for cultivating scallops include placing adult and grown scallops in round cages (trade: Chiyochin).
scallops (adult scallops)
There are three methods: one is to make a hole in the selvage part of the selvage rope and connect the selvage string to the selvage rope, and then connect the selvage string to both the left and right sides of the selvage rope.

By the way, in order to increase the growth of scallops cultured with ears, the scallops are pulled out of the sea during the cultivation period (after summer and around October), and work is done to remove and wash the deposits that have adhered to the surface of the scallops. There is.

This work is carried out in the ear-hung configuration, and there are two main methods: using a brush to remove the deposits, and using pressurized water to remove the deposits. The former brush method maintains the natural shape of ear-hanging culture without any pressure, and brushes both sides of the shellfish at once through a pair of rotating left and right brushes.
As a result, there is a problem that many shells fall out due to strain and the breakage of the ear hanging thread or damage to the ear hanging hole. In addition, in the latter case where pressured water is used, if the shellfish is treated in its natural shape during aquaculture, the shellfish will be in an upright shape, so pressurized water will enter from the seawater injection port near the ear of the shellfish, causing the The problem is that the mortality rate during aquaculture is high, which is estimated to occur during aquaculture.

By the way, during underwater cultivation of ear-suspended shellfish, shellfish and shellfish or hanging lines, hanging cords, etc. may become entangled, or seaweed, algae, etc. may adhere to the shellfish, resulting in inconsistent orientation of the shellfish. Therefore, the above-mentioned problems occur in the work of cleaning and removing deposits.

(Problems to be Solved by the Invention) The present invention has been developed in view of the above-mentioned conventional circumstances, and even if the shellfish supplied on the conveyance path where the cleaning work is carried out is carried out in the selvedge-hung shape, the selvage line is The purpose is to prevent pressure water from entering from a seawater injection port even if there is cutting, damage to the ear hanging hole, or pressure water is used.

(Means for Solving the Problems) The technical means taken by the present invention to solve the above problems is that a shellfish receiving plate is arranged on the entrance of the conveyance path, and a shellfish is pressed on the shellfish receiving plate. The plate is characterized in that the pressing force can be adjusted and the plate is arranged so as to be swingable in a direction perpendicular to the moving direction of the cultured shellfish.

The above conveyance path is a conveyor and an endless belt.
Alternatively, any material that can flatly receive and support the shellfish, such as an endless belt net, may be used, and the conveyance path may have a chevron-shaped side surface or a general horizontal shape.

(Function) According to the above configuration, since the shellfish pushing plate arranged correspondingly on the shellfish receiving plate can adjust the pressing force and swing freely in the left and right direction, the ear-hanging shellfish supplied on the shellfish receiving plate can It is leveled by the left and right rocking and pressing force of the shell pressing plate, and
The stacks of shells are removed and the surface of each shell is exposed.

Further, above the terminal end side of the shell receiving plate 27, a shell pressing plate 30 having a width narrower than the width of the shell receiving plate 27 is arranged so as to be able to freely adjust the pressing force and swing freely in the width direction.

The shell press plate 30 has a substantially trapezoidal front shape, and a support shaft 31 is integrally fixed horizontally at approximately the center in the vertical direction, and both ends of the support shaft 31 are attached to the machine frame 3.
It is supported by a bearing 33 so as to be swingable in the left and right width direction. Further, a pressing force adjustment means 34 composed of a screw rod 34a and a spring 34b is provided between the upper end of the shell pusher 30 and the machine frame 32, and the screw rod 34a
When the screw rod 34b is rotated and pulled up, the tip of the shell press plate 30 is strongly urged against the shell receiving plate 27 side, and when the screw rod 34b is rotated and pushed down, the tip of the shell press plate 30 is pushed upward from the upper surface of the shell receiving plate 27. It acts in the direction of separation, and the urging force becomes weaker.

Furthermore, the mechanism for swinging the shellfish pushing plate 30 in the left-right direction is a connecting rod 3 that is engaged with the support shaft 31 of the shellfish pushing plate 30.

When the eccentric rotating plate 36 is rotated by belt transmission, the connecting rod 35 swings about the support portion with the mounting plate 39, and the support shaft 31 swings in the left-right direction.

Therefore, the ear hangers supplied onto the shell receiving plate 27 are flattened by the pressing force of the shell pushing plate 30 and the rocking motion in the left and right direction, and the overlapping of the shells is also prevented from being caused by the shell pushing. The rocking of the plate effectively unravels the surface of each shellfish, exposing the surface of each shellfish, allowing subsequent cleaning operations to be carried out efficiently.

(Effects of the Invention) As described in detail above, the shellfish posture correcting device in the washing apparatus for ear-suspended cultured shellfish of the present invention has a shellfish receiving plate disposed above the entrance of the conveyance path, and a shellfish pushing plate placed on the shellfish receiving plate. are arranged to be able to adjust the pressing force and to be able to swing in a direction perpendicular to the moving direction of the ear-hanging cultured shellfish, so the ear-hanging shellfish supplied to the shellfish receiving plate can be swung left and right while being pressed by the shellfish pushing plate. The shells are leveled evenly, and the mutual overlapping of the shellfish is reliably released, exposing the surface of each shellfish, and the cleaning work of the shellfish surface can be carried out efficiently.

Moreover, since the shell pressing plate swings from side to side, the pressing force is weaker than when only a simple pressing force is applied, and therefore the hanging line is not cut or the hanging hole is not damaged due to the pressing force. The shellfish is leveled.

Therefore, it is possible to provide a posture corrector essential for a shell surface cleaning device for ear-suspended cultured shellfish.
