Problems solved by technology

[0004] When the above two types of kelp harvesting ships are used for operations, due to the up-and-down movement of the horizontal position of the kelp seedling ropes, it is difficult to grab the seedling ropes and cut the slings at both ends of the kelp seedling ropes, and the operating efficiency has not been significantly improved. It is very easy to form a situation where kelp is missed
In addition, because the whole seedling rope is in a flexible state, the above two types of kelp harvesting ships cannot realize the smooth transportation of the whole seedling rope when they are transported by the towing device. The arrangement is messy, which brings great difficulties to the unloading operation in the later stage
[0005] In addition, the Chinese patent document with the publication number CN112293052A discloses "a device and method for continuously cutting and harvesting kelp with long seedling rope", which solves the problem of continuous harvesting of kelp, but in the process of stroking and cutting, the roots of kelp The ball (the kelp is bound on the seedling rope will form a "root ball", and the "root ball" is also a part of the kelp itself) will stay on the root handle, which is not conducive to the blanching of kelp

Embodiment 1

[0035] see Figure 1-Figure 2 , an integrated cutting tool structure for long seedling rope kelp root stalk cutting and root ball stroke cutting, which adopts an inner and outer double-layer rotating shearing structure, and the outer layer cutting knife (the first relative rotating knife body) protrudes from the inner layer to the right The stroke cutter (the second relatively rotating cutter body), the diameter of the cutting circle is in contact with the upper part of the kelp root stalk.

[0036] The first relative rotating cutter body comprises the outer fixed cutter 6 and the outer layer rotating cutter 7, the circumferential end face is serrated, there are blades on both sides of the serration, the blade of the outer fixed peripheral cutter is positioned at the inner side of the circumference, and the blade of the inner rotating peripheral cutter is positioned at the outer side of the circumference, The gap between inner and outer knife is less than 1mm. When the rotati...

Embodiment 2

[0048] see Figure 6-7 The difference between this embodiment and Embodiment 1 is that the outer fixed knife 6 is not a circumferential knife, but includes 4 independent knife bodies, and the outer rotating knife 7 is not a circumferential knife, but includes 4 corresponding an independent blade.

[0049] Compared with the first embodiment, the second embodiment is more convenient for rapid removal of debris in the process of removing the kelp root stalk. Such as Figure 7 As shown, the chip discharge hole 13 formed in this embodiment is in a dynamic state, so the effect of chip removal is better; meanwhile, the knife mode in embodiment one can only discharge kelp debris from the chip discharge hole 13; In example two, in addition to being discharged from the chip discharge hole 13, the kelp debris can also be quickly discharged from the gap between the knives.

Abstract

The invention relates to a long seedling rope kelp root stem slitting and root ball stroking cutting integrated cutter device. The device is characterized in that a fixed body comprises an outer side fixed cutter with a large outer diameter and an inner side fixed circumferential cutter with a small outer diameter, wherein the outer side fixed cutter and the inner side fixed circumferential cutter are coaxially arranged; a rotating body is located in the area between the outer side fixed cutter and the inner side fixed circumferential cutter and comprises an outer layer rotating cutter and an inner layer rotating stroking cutter; the outer side fixed cutter and the outer-layer rotating cutter form a pair of first relative rotating cutter bodies capable of relatively moving and cutting the kelp root stems; the inner side fixed circumferential cutter and the inner layer rotary stroking cutter form a pair of second relative rotating cutter bodies capable of relatively moving and cutting the kelp root balls into pieces; the inner diameter of the second relative rotating cutter bodies is larger than the outer diameter of a seedling rope knot and smaller than the outer diameter of kelp root balls; the first relative rotating cutter bodies are located in front of the second relative rotating cutter bodies, so that the first relative rotating cutter bodies firstly shear the kelp root stems, and then the second relative rotating cutter bodies shear the kelp root balls of which the kelp root stems are sheared into pieces.

Description

technical field [0001] The invention relates to an integrated tool device for cutting the root stalk and cutting the root ball of kelp with a long seedling rope, and belongs to the technical field of kelp harvesting rope and cutting. Background technique [0002] As an important economic value of seaweed, kelp has extremely high edible value and industrial value. At present, there is no mature plan for the kelp harvester, and most of them are in the design and development stage of the principle prototype. The harvesting principles are mainly divided into two categories. One is to set up a pulling rod and a dragging device on the hull, drag the kelp seedling rope to the hull, and then manually untie the rope, thereby reducing the intensity of manual dragging. The second is to increase the rope cutting device on the hull, directly cut off the suspension rope at the two ends of the kelp seedling rope from the frame rope and then drag it to the hull by the dragging device. ...
