Description

[Detailed Description of the Invention] Since seaweed farming is carried out in conjunction with nature, the production equipment and quality of the year vary significantly depending on seawater pollution, sea conditions, weather, etc.; While production is often reduced due to outbreaks of rot, white horse disease, chytrid fungi, etc., or lack of fertilizer nutrients, etc., it is extremely difficult to take preventive measures against these, and some individuals Disinfectants and fertilizer nutrients are sprayed on the farm, but they are not effective, and when various diseases occur, there is no other option than to remove the seaweed nets that are being stretched. However, due to the lack of labor and the lack of suitable care equipment, disease prevention and fertilization could not be carried out reliably.

The present invention aims to eliminate the above-mentioned drawbacks and improve the quality of seaweed raw algae, by installing a seaweed picking machine and a soaking device on a seaweed picking boat, and using this equipment to harvest seaweed raw algae. This invention relates to a method characterized in that operations from plucking to immersion sterilization of seaweed nets and fertilization are carried out continuously.

The configuration of the apparatus used to implement the method of the present invention will be described below.

A seaweed picking machine (2) is installed on the seaweed picking boat (1), and a seaweed net dipping device (4) comprising a liquid tank (3) is installed at the rear of the ship (1). A nori net guide roll (5 mm) is mounted on the front part higher than the edge of the ship, and the free transfer is mounted on a shaft rack for automatic rotation. Furthermore, multiple guide rolls (5) are installed from the front end surface of the safety cover L6J of the nori picking machine to the guide roll (5). tengai (r)
lJ loosely connected, a partially opened shaft support ring (9J(d)) is attached to the opposing position of both side walls (81t8'J) of the liquid tank (3), and a pressing roller (10) is attached to the surface support ring. ] axis (lIJ
Using the above-mentioned device configured by loosely fitting both ends of the seaweed, the seaweed picking machine (2) successively picks the seaweed algae 1 (13) that has grown on the seaweed net (12), and the harvesting of the seaweed is completed. The seaweed net is immersed in the liquid stored in the liquid tank of the dipping device (4) installed at the rear while being pressed by a presser roller, so that processing operations such as disinfection and fertilization of the seaweed net and raw algae are carried out. It is made up of:

Next, the functions and effects of the method of the present invention will be explained with reference to practical example diagrams.

The present invention utilizes a device configured as described above, and stores a predetermined amount of disinfectant, fertilizer, etc. in the liquid tank (3J) of the soaking device (4) at a seaweed farm. The prime mover rotates the picking blade of the seaweed picking machine (2) at an appropriate speed, and the worker pulls up the seaweed raw algae (13 ribs; grown seaweed net Cl2) from all sides and puts it on the guide roll (
5) Each Tengai C' from the top? By placing the seaweed on the top of the nori picking machine via the top surface of the seaweed net, and moving the seaweed picking boat (1) forward while pulling the seaweed net, the raw seaweed hanging from the seaweed net is completely removed by the rotating picking blade. The part of the seaweed net that has been picked is guided by the operator to the liquid tank (3) and immersed in the stored liquid,
The pressure rollers (1, 0) press the seaweed net from two sides to prevent the seaweed net from floating during dipping. After dipping, the seaweed net is placed on the rear edge of the liquid tank or in the water drainer. The liquid is drained by a rod and unneeded liquid is removed, and the liquid is dropped onto the sea surface sequentially from the edge of the immersion device.
When the capacity of the seaweed net reaches the position of the presser roller, the workers on both sides pass the rope around the end of the shaft (11) through the opening of the support ring (9) 49), and By pulling out the rope from the opening, the capacitive rope can be easily escaped and passed backwards.

As mentioned above, by using a nori picking machine and a dipping device consisting of a liquid tank in series, it is possible to disinfect and fertilize seaweed nets, which were difficult and almost impossible in the past. The maintenance work can be carried out continuously and at the same time while picking the seaweed raw algae, and the trouble of double work is completely eliminated, and disinfection by constant immersion,
It can be used for treatments such as fertilization, and is extremely effective in preventing diseases and promoting the growth of raw algae.

In addition, by performing continuous dipping work while picking raw algae, labor shortages can be completely resolved, and by processing and caring for seaweed nets using the method of the present invention, the quality of seaweed can be significantly improved. The present invention has the above-mentioned remarkable effects in seaweed cultivation work, such as increasing the production amount.

Claims (1)

[Claims] A seaweed picking machine is loaded onto a seaweed picking boat, a dipping device with a liquid tank is installed at the rear of the boat, and a guide roll of a seaweed net is installed at the front of the seaweed picking machine a little higher than the edge of the ship for free rotation or automatic operation. A shaft is mounted on the shaft so that it can rotate freely, a plurality of tengai are loosely connected to the guide roll from the front end surface of the safety cover of the nori picking machine, and a shaft support ring with a partially opened part is attached to opposite side walls of the liquid tank. Utilizing the above-mentioned device, which is constructed by loosely supporting a pressure roller for a seaweed net on a shaft support ring, a seaweed picking machine is used to pluck the raw seaweed that has grown into a seaweed net, and then the nori net that has been picked is pulled backwards. A method for picking seaweed raw algae and dipping a seaweed net, which comprises immersing the seaweed net in a liquid stored in a liquid tank while pressing it with a pressure roller to disinfect and fertilize the seaweed net and remaining raw algae. 0
