Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaning device for removing deposits on a fishing net used for aquaculture of fish and the like.

[0002]

[Prior Art]

 The fish cages used for aquaculture have a structure in which fishing nets are stretched around and around the bottom of the fish cages.When such fish cages are used, shellfish and seaweeds such as oysters and barnacles adhere to the fishing nets, and As the size of the fish becomes smaller, it prevents the inflow and outflow of seawater, and the food left over from feeding does not fall from the water, so it causes oxygen deficiency and kills the cultured fish. I need to do it.

Conventionally, in cleaning a fishing net as described above, a worker holds a nozzle attached to the tip of a hose by hand and sprays water toward the fishing net for cleaning.

[0004]

[Problems to be solved by the device]

By the way, since the fishing net has a size of, for example, 8 to 13 m ² , it is extremely heavy, and it requires heavy labor to wash it manually, and several workers are required, resulting in poor work efficiency and cleaning. There is a problem that the cost is high.

Further, it is very difficult to wash the back side of the fishing net surely by manual cleaning, and the fishing net is reused under the condition that the adhered matters remain.

Therefore, the present invention provides a fishing net cleaning device capable of automatically cleaning the fishing net, saving labor and improving efficiency of the cleaning work, and reliably cleaning the fishing net with high-pressure water. It is an issue.

[0007]

[Means for Solving the Problems] In order to solve the above problems, the present invention is directed to a horizontal winding roller for winding a fishing net and a winding roller which is disposed in the vicinity of the winding roller. , Which moves back and forth in parallel with the axial direction of the arm, an arm attached to this arm whose front end faces the upper part of the fishing net that is wound toward the winding roller, and a mount that rotates horizontally at the front end of this arm. And a plurality of pressure water injection nozzles for injecting high pressure water toward the fishing net to be wound up toward the take-up roller. The pressure water injection nozzle is configured to be capable of adjusting the injection angle of the high pressure water. It was adopted.

[0008]

[Action]

 If the pressure water jet nozzle is rotated and the carriage is moved while the fishing net is spread in a plane and high-pressure water is jetted from the pressure water jet nozzle toward the fishing net, the width of the rotating diameter of the jet nozzle will be reduced. Wash the fishing net horizontally.

When the trolley stops at one end of the reciprocating motion, the winding roller winds the fishing net for the amount of washing, the trolley moves again, and by repeating this in sequence, the entire surface of the fishing net is automatically washed. Can be wound up.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the cleaning device includes a horizontal take-up roller 1 for intermittently taking up the fishing net A, and a position near the take-up roller 1 along the axial direction of the take-up roller 1. The carriage 2 arranged so as to reciprocate, the arm 3 attached to the carriage 2, the plurality of pressure water jet nozzles 4 attached to the tip of the arm 3, and the carriage 2 in the vicinity of the take-up roller 1. It is configured by a board sludge 5 arranged on the floor surface on the opposite side.

The take-up roller 1 is slightly longer than the width of the fishing net A, has flanges 6 and 6 at both ends thereof, and has a plurality of net hooks 7 in the axial direction of the outer peripheral surface. Is rotatably supported by the bearings of the support bases 8 and 8 and is in a horizontal arrangement.

The winding roller 1 is driven via a clutch 10 by a motor 9 provided on one of the support bases 8 and rotates so as to intermittently wind the fishing net A by the length for cleaning.

The trolley 2 has wheels 12 mounted on a pair of rails 11 and 11 laid on a floor surface opposite to the side where the fishing net A is arranged with respect to the winding roller 1, and a gear motor 13 with a clutch. The wheel 12 is driven to reciprocate in parallel with the axial direction of the take-up roller 1, and its moving range is set by the limit switches S ₁ and S ₂ .

The arm 3 attached to the trolley 2 is formed by using a pipe such as stainless steel, and the rear end side is supported by the trolley 2 so as to penetrate the trolley 2 in the front-rear direction, and the middle of the arm 3 is an upper portion of the winding roller 1. It is arranged so that it passes through at a right angle and the tip faces directly above the board sludge 5.

The arm 3 can be adjusted in position by sliding back and forth along the length direction thereof, and the high-pressure water hose 14 and the power cord are inserted inside from the rear end side and pulled out to the front end. There is.

A rotary cylinder shaft 16 vertically supported by bearings is provided in a head box 15 provided at the tip of the arm 3, and the tip of the high-pressure water hose 14 is provided at the upper end of the rotary cylinder shaft 16 with a rotary joint 17. The rotary cylinder shaft 16 is rotated by a gear motor 18 provided in the head box 15.

A branch pipe 19 that projects in four directions in a horizontal state is connected to the lower end of the rotary cylinder shaft 16 that projects downward from the lower surface of the head box 15, and pressure water is applied to the tip of each branch pipe 19 that bends downward. Nozzle 4 is attached.

Two jet nozzles 4 are attached to the tip of each branch pipe 19, and the jet angles of the high-pressure water jetted downward from each jet nozzle 4 can be adjusted.

FIG. 3 shows an example of a structure for adjusting the angle of the injection nozzle 4, in which an angle variable joint 20 is provided between the branch pipe and the injection nozzle 4, and the angle of the injection nozzle 4 after the adjustment is adjusted by a tightening bolt 21. It can be fixed.

The cleaning device of the present invention has the above-described structure, and the plate saw 5 is laid on the floor surface opposite to the carriage 2 with the take-up roller 1 interposed therebetween, and the high-pressure water hose 14 serves as a high-pressure pump. In the connected state, the angle of the jet nozzle 4 is set, the end of the fishing net A to be washed is spread over the plank saw 5, and high pressure water using seawater or the like is supplied toward the jet nozzle 4 in this state. At the same time, the motor 18 is activated to rotate the injection nozzle 4 as indicated by the arrow in FIG.

Each of the jet nozzles 4 jets high-pressure water toward the fishing net A immediately below while rotating in a plane around the rotary cylinder shaft 16, and at the same time moves the cart 2.

The high-pressure water jetted from the jet nozzle 4 collides with the fishing net A supported on the plank saw 5 to remove the adhering matter on the fishing net A, and also to remove the net A from the plank saw. By supporting with 5 and setting the angle of the spray nozzle 4, pressure water acts not only on the front surface but also on the back surface side, so that the fishing net can be reliably washed.

By rotating the jet nozzle 4 and moving the carriage 2, the entire length of the fishing net A in the width direction can be washed with the width of the rotating diameter of the jet nozzle 4, and by stopping at one end of the cart 2, the fishing net A is stopped. The end of the net A is locked to the outer circumference of the take-up roller 1 using the hook 7, the motor 9 is activated to rotate the take-up roller 1, and the fishing net A is wound by the washed length.

The fishing net A is washed again by supplying high-pressure water, rotating the jet nozzle 4 and moving the jet nozzle 4 to the opposite side. The entire length of the fishing net A can be automatically washed.

[0026]
