Description

  The present invention relates to a laver picking apparatus. More specifically, the present invention relates to a product that can be surely picked up with no unevenness when picking up the laver attached to the laver net, and that the power required to rotate the rotary cutter is relatively small.

The cultured seaweed grows while adhering to a seaweed net stretched on the sea surface, and is picked by a seaweed picking device equipped with a rotary cutter.
The conventional laver plucking device is configured so that the blade line portion of the rotary cutter blade gently draws a spiral in the axial direction of the rotary shaft, and only a part of the blade line portion in the longitudinal direction always has the laver. The load is reduced by cutting the power and the power required to rotate the rotary cutter is relatively small (see Patent Document 1).

Japanese Patent Laid-Open No. 11-98913

The laver picking device provided with a rotary cutter having a spiral blade has the following problems.
That is, in the blade body having the above-described configuration, the direction of the blade line portion is slightly inclined rather than perpendicular to the rotational movement direction of the blade. If the object to be cut is relatively hard or fixed, the cutting efficiency is not so different whether it is perpendicular or inclined.

However, in the case of a laver picking device, the object to be cut by the rotary cutter is a soft, semi-fluid laver leaf attached to the laver net. For this reason, even though the rotary cutter is rotating at high speed, when the soft laver is cut by the blade line portion, the cutting force component direction (the axis of the rotating shaft) Run away).
Therefore, plucking unevenness (unpulling) tends to occur on the entire surface of the laver net, and fundamental measures to solve various problems such as contamination of aged laver leaf bodies and the occurrence of disease caused by this. It was not.

  The term “seaweed attached to a laver net” as used in the claims and specification refers to a laver leaf body (leaf-like body) that grows attached to the laver net.

  The number of blades divided in the axial direction of the rotating shaft is, for example, 2 to 6, but may be larger. Preferably, 5. The axial lengths of the rotation axes of the blades to be divided may be the same or different.

  The number of the rotating shafts of the blade body in the circumferential direction is not particularly limited. The intervals in the axial direction of the blades may be equal or different. Furthermore, all the blade line portions of the divided blade bodies may be at different positions in the axial direction of the rotation shaft, or some of them may be at the same position.

(Function)
The operation of the laver plucking device according to the present invention will be described. In addition, here, each constituent element of the present invention is given and described in association with the reference numerals given to the respective parts in the embodiments to be described later. However, the provision of these reference signs makes it easy to understand the explanation. Therefore, it does not mean that each constituent element is limited to the above-described parts.

A laver picking device is placed on a laver collecting ship, and while the rotary cutter (2) is driven, the laver collecting ship is moved so as to be hidden under a laver net (N) on the sea surface of the farm.
As a result, the laver net (N) relatively moves through the vicinity of the rotary cutter (2), and the laver attached to the laver net (N) (the laver leaf body) is rotated by the rotating rotary cutter (2 ) Are cut and picked by the blade line portion (240) of each blade body (24).

  The blade (24) of the rotary cutter (2) is divided into a plurality of parts in the axial direction of the rotary shaft (21), and the blade line portion (240) of each blade (24) is the axial circumference of the rotary shaft (21). The position is shifted in the direction. Thus, when the rotary cutter (2) rotates and each blade body (24) cuts the laver with the blade line part (240), each blade line part (240) is in the feeding direction of the laver net (N). The laver in the same position is not cut at a time, and the load at the time of cutting is distributed, so the power required to rotate the rotary cutter (2) can be relatively small.

  Moreover, the direction of the blade line portion (24) is essentially parallel to the axial direction of the rotating shaft (21). As a result, unlike the conventional structure in which the blade line portion is configured to draw a spiral, the component force of the cutting force when cutting the laver (in the axial direction of the rotating shaft) does not occur, and it is soft and semi-fluid A typical laver leaf body can be reliably cut with a stronger cutting force.

  The blade body (24) is provided with a plurality of ring bodies (25) having essentially the same diameter as the rotation trajectory of the blade line portion (240) at a required interval in the axial direction of the rotation shaft (21). Even if N) hangs down and comes into contact with the rotary cutter (2), the ring (25) prevents or reduces the laver net (N) from directly contacting the blade line (240) of the blade (24). be able to.

What has the means (5) for adjusting the angle or height which guides a laver net (N) toward the rotary cutter (2) acts as follows.
That is, when the installation position in the direction of travel of the laver picking device (A) in the laver collection ship is changed, the angle of the laver net (N) guided to the rotary cutter (2) also changes. The induction angle of the laver net (N) can be appropriately adjusted to an angle or height suitable for picking the laver.

(A) According to the present invention, the blade body of the rotary cutter is divided into a plurality of parts in the axial direction of the rotary shaft, and the blade line portions of each blade body are shifted in position in the axial circumferential direction of the rotary shaft. As a result, when the rotary cutter rotates and each blade cuts the seaweed at the blade line part, the blade line part does not cut the seaweed at the same position in the feed direction of the nori mesh at the same time. Since the time load is also distributed, the power required to rotate the rotary cutter can be relatively small.
Further, the direction of the blade line portion is essentially parallel to the axial direction of the rotation axis. As a result, unlike the conventional structure in which the blade line portion is configured to draw a spiral, the component force of the cutting force when cutting the laver (in the axial direction of the rotating shaft) does not occur, and it is soft and semi-fluid A typical laver leaf body can be reliably cut with a stronger cutting force.
Accordingly, uneven plucking (unpulling) is unlikely to occur on the entire surface of the laver net, and it is possible to solve various problems such as contamination of aged laver leaf bodies and the occurrence of diseases caused by this.

(B) Even if the blade body is provided with a ring body having the same diameter as the rotation trajectory of the blade line portion at a required interval in the axial direction of the rotation shaft, even when the laver net hangs down and contacts the rotary cutter, It is possible to prevent or reduce the contact of the laver net directly with the blade line portion of the blade body. Thereby, damage to the blade line portion of the blade body and the laver net can be prevented.

(C) When having a means for adjusting the angle or height for guiding the laver net to the rotary cutter, the installation position in the traveling direction of the laver picking device in the laver collection ship is changed The angle of the laver net that is guided toward the rotary cutter also changes. By this means, the induced angle of the laver net can be appropriately adjusted to an angle or height suitable for picking the laver.

(Function)
FIG. 5 is an explanatory diagram of the use state of the laver plucking device. With reference to FIG. 1 thru | or FIG. 5, the effect | action of the laver picking apparatus A which concerns on this Embodiment is demonstrated.

As shown in FIG. 5, the seaweed picking device A is placed on the seaweed collecting ship S and installed. Next, while driving the rotary cutter 2 with the prime mover 4, the laver collecting boat S is moved so as to be hidden under the laver net N stretched on the sea surface of the farm.
At this time, each laver net derivative 5 is appropriately adjusted so that the induction angle of the laver net N becomes an angle or height suitable for picking the laver.

  Thereby, the laver net N is guided to slide on each laver net derivative 5 and relatively moves through the upper part of the rotary cutter 2. And the laver (laver leaf body) attached to the laver net N is cut and picked by the blade line portions 240 of the blades 24 of the rotating rotary cutter 2. The picked nori accumulates on the bottom of the ship.

  Even when the laver net N is in contact with the rotary cutter 2 that is hanging and rotating, the laver net N is in direct contact with the blade line portion 240 of the blade 24 by the ring 25 provided on the blade 24. Can be prevented or reduced.

  Note that the blade body 24 of the rotary cutter 2 is divided at the partition portions d1, d2, d3, d4, and d5, and the blade line portion 240 is shifted in the axial circumferential direction of the rotary shaft 21 at the adjacent partition portions. . Thereby, when the rotary cutter 2 rotates and each blade body 24 cuts the laver at the blade line portion 240, each blade line portion 240 cuts the laver at the same position in the feeding direction of the laver net at a time. There is no.

  Specifically, the blade line portions 240 of the blade bodies 24 of the partition portions d1, d3, and d5 simultaneously cut the seaweed, and the blade line portions of the blade bodies 24 of the partition portions d2 and d4 are instantaneously shifted in time. 240 cuts simultaneously. Thereby, since the load concerning the rotary cutter 2 at the time of cutting nori is also distributed, the power required to rotate the rotary cutter 2 can be relatively small.

  In addition, the direction of each blade line portion 240 is essentially parallel to the axial direction of the rotating shaft 21. Thus, unlike the conventional configuration in which the blade line portion 240 is configured to draw a spiral, the component force of the cutting force when cutting the laver (in the axial direction of the rotating shaft) does not occur, and it is soft and half A fluid laver leaf can also be reliably cut with a stronger cutting force.

  Note that the terms and expressions used in the present specification are merely explanatory and not restrictive, and do not exclude terms and expressions equivalent to the above terms and expressions. The present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the technical idea.
