Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laver picking machine mounted on a laver picking work boat. 2. Description of the Related Art As a laver picking machine mounted on a laver picking work boat, a nori leaf body that has grown and drooped on a laver net with an angle-shaped rotating blade in a vertical lattice (hereinafter referred to as tengai) is used. An automatic seaweed harvester is described in Japanese Utility Model Publication No. 43-27659. [0003] In addition, a seaweed picking machine in which the number of tengai arranged is reduced and a round bar is provided on the outer periphery of a rotating plate for holding and fixing the picking blade to prevent the seaweed net from breaking is registered.
No. Design Bulletin. In addition, a nori picker with a round bar ring arranged around the outer periphery of the rotary cutter to reduce the number of tengai is also used. [0004] The above-mentioned Japanese Utility Model Publication No. 43-27
No. 659, a laver automatic reaper,
A slight loosening of the laver net increases the distance between the tengai and the work efficiency is reduced due to the problem of encroaching and breaking the laver net, and narrowing the distance between the tengai leaves much of the nori leaf cut off, resulting in disease at the next plucking There is a problem that it causes generation and quality deterioration, and it is difficult to bring the laver net close to the cutting blade, so that the yield is reduced. In addition, during the disease outbreak stage, it was not possible to pick the fish in a short time, and it was not possible to perform the flycatcher work performed by removing the ruler or the cover that is a member constituting the main body of the picker at the end of the fishing season. [0005] In the laver picker described in the registered Japanese Patent No. 480837, the occurrence of disease can be prevented to some extent by reducing the number of tengai. However, when the movement of the work boat relied on human power, it was possible to work so that even some picking could be done by pulling the laver net with human power and shaking it so that there would be no unpicked residue. The picking speed was doubled because the movement of the turtle was changed to power propulsion, and the picking part of the tengai part was left unpinched.In addition, the picked laver collected around the pipe-shaped reinforcement supporting the tengae was collected in a layered manner and wound around it Had become an obstacle. As described above, it is possible to reduce the number of tengai by using a round bar ring provided on the outer periphery of the rotary cutter, but the picked laver is wrapped around the round bar ring itself to cause clogging. In proportion to the speeding up of the plucking, the seaweed often wraps around the whole rotary cutter due to the blade clogging, and it is difficult to remove the seaweed from the blade clogging. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has a rotatable rotary cutter mounted on a work boat for seaweed picking and rotatable on both side plates of the body of the seaweed picking machine. A laver picking machine, wherein a plurality of rotating disks are communicated with a pipe-shaped shaft center member of the rotary cutter and arranged at small intervals, and the outer peripheral portion of the rotating disk is bent inward and rounded to the outer peripheral end. forming a, as well as constitute a <br/> rotary cutter supported on the rotation disk a hysterectomy saw blade a tip portion of its is infiltrated slightly inward from the outer peripheral edge of the rotary disc, the knob main body Characterized in that an arch-structured net receiving pipe is installed in front of. The laver picking machine of the present invention has a structure in which a plurality of rotating disks constituting a rotary cutter are arranged at small intervals, and a net receiving pipe having an arch structure is provided in front of the body of the picking machine. In addition, the conventional tengai and the pipe reinforcing member for supporting and fixing the lower part of the tengai can be eliminated, and the range in which the rotary cutter can be directly viewed from the upper surface besides a ruler for adjusting the length of nori at the time of plucking is opened. By arranging the rotating disks at small intervals to form a wall state, the rotating disks serve as net supports in place of the conventional tengai, and also prevent blade clogging. In the laver picking machine of the present invention, the upper surface of the rotary cutter is open because there is no barb, and the laver picked from the laver net can be completely dropped into the rotary cutter. Since there is no pipe-shaped reinforcing member for supporting the lower part of the tengai, the picked seaweed does not accumulate on the scaffold, and the picking operation becomes smooth. In addition, since there is no tengai, it is possible to prevent the seaweed net from being entangled and the seaweed leaf from being left uncut. [0010] Since the rotating disks constituting the rotary cutter are arranged at small intervals and the outer peripheral portion is bent inward to form a rounded outer peripheral end, the nori net contacts the outer peripheral portion of the rotating disk. Even so, there is an effect of flipping the laver net due to the rotating force of the rotating disk, and the winding of the laver net is prevented. In addition, the back side of the picking blade has a radial configuration that promotes the release of laver leaf bodies, while the inner surface side of the picking blade has the effect of sending pressure air to the rear partition part partitioned by the picking blade by rotation,
Prevent clogging of laver. Furthermore, by positioning the tip of the knob slightly inside the outer edge of the rotating disk,
Even when the contact pressure of the laver net is high, cutting and entrainment of the laver net are prevented. The arch-shaped net receiving pipe installed in front of the knob body has the function of supporting and spreading the laver net. Further, the nori net is supported above the sea surface by the upper end of the net receiving pipe and the upper end of the knob body, so that the nori net passes smoothly. FIG. 1 is a schematic front view showing a laver picking machine according to an embodiment of the present invention, and FIG. 2 is a schematic side view. In FIG. 1, the rotary cutter 5 is mounted on bearings 7a, 7 on the bearing mounting side plate 3 of the knob body 1.
The shaft is supported by b, the power is transmitted by the pulley 6, and the rotary cutter 5 is rotated. A rear cover 1a is provided on the rear surface of the knob body 1, and a ruler 2 that can be adjusted to move forward and backward is disposed on the rear cover 1a. A net receiving pipe 10 having an arch structure including a part of a straight portion is installed in front of the knob body 1. FIG. 3 is a plan view of the laver picking machine with the ruler 2 removed, and FIG. 4 is an enlarged cross-sectional view taken along line AA ′ of FIG. In the laver picking machine of this embodiment, there is no tenge for receiving a net and a pipe-like reinforcing member for supporting and fixing the same in the conventional laver picking machine.
The front side is Tsu Do not open structure of. A large number of rotating disks 4 constituting the rotary cutter 5 are arranged at small intervals in communication with a pipe-shaped shaft member 9. Rotating disk 4
The group and the back cover 1a are installed at appropriate intervals. FIG. 5 is an enlarged detailed view of the rotary disk 4 and the knob 5a. The cutting edge of the U-shaped knob 5a is sunk into the outer peripheral portion 4a of the rotary disk 4. Outer peripheral portion 4 of rotating disk 4
“a” is formed by bending a thin plate inward to form a round shape, and the corners of the knob 5 a only slightly protrude from the outer periphery of the rotating disk 4, and most of the corners sink into the outer peripheral portion 4 a. FIG. 6 is a schematic diagram of the seaweed picking operation. The picker body 1, the power engine 14 for the handwheel, and the outboard motor 12 for propelling the seaweed are placed on a work boat (plucking boat) 11, and the seaweed net 1
3. The hanging net 15 passes through the upper end of the net receiving pipe 10 and the upper end of the knob body 1 and passes over the work boat 11 to perform the seaweed picking operation. The laver picking machine of the present invention has a plurality of rotating disks constituting a rotary cutter arranged at small intervals, and a net receiving pipe having an arch structure in front of the body of the picking machine. By installing, the seaweed of the conventional laver picking machine can be eliminated, and the seaweed picked from the laver net can be completely dropped into the rotary cutter. Further, since there is no pipe-like reinforcing member for supporting the lower part of the tengai, the picked laver does not accumulate on the scaffold, and the picking operation becomes smooth. By arranging the rotating disks constituting the rotary cutter at small intervals, and bending the outer peripheral portion inward to form a rounded outer peripheral end, the seaweed net is prevented from being involved. In addition, by locating the tip of the picking blade slightly inside the outer peripheral end of the rotating disk, cutting and entanglement of the laver net can be prevented. By eliminating the conventional tengai,
There is no irregularity of nori after plucking, which is effective in preventing disease and increasing yield, reducing net cutting and entanglement, eliminating laver accumulation that hinders work, and enabling high-speed plucking.
