Detailed Description
The invention will be further described with reference to the drawings and specific examples.
Referring to fig. 1-6, a lift drag-free kelp lift cutting system comprising: a lifting system composed of a pair of lifting units 11 which move synchronously; a lifting system consisting of a pair of kelp lifting units 21 which move synchronously, the kelp lifting units 21 being placed on the lifting units 11 and moving up and down together with the lifting units 11; the kelp lifting unit 21 is a transmission system which is vertically arranged and is closed from end to end; a cutting system 30 is fixedly arranged in the rear area between the pair of kelp lifting units 21, and a slide 40 with a lower front and a higher rear is arranged in front of the cutting system 30 and is used for receiving and transferring the kelp tips which are cut; a conveyor system 50 is arranged right below the cutting system 30 and is used for receiving and transferring the cut kelp main body; the conveyor system 50 is a belt conveyor system that conveys backward at the same rate as the conveying rate of the downleg in the closed-end hoist system unit 21.
In this embodiment, referring to fig. 5, the lifting unit 11 is composed of not less than 2 electro-hydraulic pushers 12 and an integrated frame 13 disposed above the electro-hydraulic pushers 12, the integrated frame 13 being a base on which the kelp lifting unit 21 is mounted.
In this embodiment, referring to fig. 6, the kelp lifting unit 21 is a chain conveying system, a hanger 22 is provided on a conveying chain 24, the conveying chain 24 is formed by a vertical ascending section, an upper horizontal moving section, a vertical descending section and a lower horizontal moving section, a closed moving path is formed, and a supporting rod 23 for mounting a seedling rope 60 is placed on the hanger 22.
In this embodiment, see fig. 6, the kelp lifting unit 21 has a support frame 25 therein, which support frame 25 is arranged so as not to impede the movement of the support bar 23 by the conveyor chain 24.
In this embodiment, referring to fig. 3-4, the upper and lower ends of the two sides of the slideway 40 are respectively and correspondingly arranged on the upper and lower horizontal bars 41 of the side of the supporting frame 25 to which each side lifting unit 21 belongs, and the slideway is moved back and forth by means of electro-hydraulic push rods 42 arranged on the horizontal bars 41 of the two sides.
In this embodiment, referring to fig. 2, the supporting rod 23 has a small hook 231 thereon, and the end of the small hook is spherical.
In this embodiment, see fig. 3-4, the hanger 22 can be closed by means of a clasp 221 and has a flap 222 on its outside to prevent the support bar 23 from slipping out of the hanger 22 due to the roll of the boat.
The specific working state is as follows: the kelp seedling rope 60 captured by the dragging system for kelp harvesting is released from the kelp culture rope and then hung on the supporting rods 23, and the small hooks 231 on the supporting rods 23 penetrate through gaps among the kelp 70 on the seedling rope, so that the kelp 70 cannot be scratched due to the fact that the front ends of the small hooks 231 are smooth small balls, then the seedling rope 60 is tensioned by personnel and fastened on the supporting rods 23, and the seedling rope 60 cannot sag in an arc shape due to the supporting effect of the small hooks 231 and the fact that the seedling rope 60 is tensioned due to the fact that the weight of the kelp 70 is discharged, so that uniformity of cutting length when the kelp 70 is cut is guaranteed. After hanging the seedling rope 60 on the support rod 23, the person places the support rod 23 on the hook 22 and buckles 221. Because the kelp 70 is mostly in the sea water and the density of the kelp 70 is only slightly higher than that of the sea water, the people can easily lift the hooks 22 on the supporting rods 23 under the buoyancy of the sea water. And then starting the lifting system to move the kelp 70 from the vertical lifting section to the upper horizontal movement section, starting the cutting system 30 by a person when entering the working area of the cutting system 30, enabling the cut kelp tips to fall into the slideway 40 and fall into the kelp tip collecting area through the slideway, starting the electro-hydraulic push rod 42 after the kelp tips are cut by the cutting system 30, pushing the slideway 40 away from the cutting system along the horizontal rod 41, simultaneously continuing to descend the kelp 70, enabling the lower end of the kelp 70 to fall onto the conveying system 50, and conveying the kelp 70 falling onto the conveying system to the kelp collecting cabin, wherein the movement speed of the lower end of the lifting system is the same as the conveying speed of the conveying system 50, so that the kelp 70 does not have relative movement on the conveying belt, namely no dragging effect. When the kelp 70 is lowered to a desired length, the cutting system 30 cuts the kelp 70 and the cut kelp 70 is transported to a kelp collection compartment. After the cutting operation, the supporting rod 23 returns to the ascending section of the lifting system 20 through the closing movement of the lifting system 20, and the personnel can open the buckles 221 to take out the supporting rod 23 for reuse. Because the kelp 70 is generally 3m-5m long, when the kelp 70 is longer and the lifting system 20 is not enough, the electro-hydraulic push rod 12 can be started to lift the integrated frame 13 to drive the lifting system 20 to lift the longer kelp 70.
The foregoing is a preferred embodiment of the present invention and various modifications can be made thereto by those skilled in the art, which modifications are intended to fall within the scope of the present invention as claimed.
