Description

Technical field:

[0002] The utility model relates to a ship-borne offshore oyster seed harvesting device. Background technology:

[0004] Early oyster seed cultivation was carried out in artificial ponds on the shore. With the increasing emphasis on environmental protection and the rising cost of land, oyster seed cultivation has shifted to the sea. Due to the high density of cultivation on the mudflats near the coast, there is a high possibility of pollution by wastewater discharge, making it difficult for fertilized oyster eggs to attach. The yield and quality of the cultivated oyster seed are low. For this reason, the cultivation of oyster seed has been transferred to hanging culture outside the bay.

[0005] The existing harvesting of oyster seedlings outside the bay relies on manual harvesting by people stationed on work boats. There are no research reports on oyster seedling harvesting equipment. Therefore, it is urgent to research an equipment that can realize offshore oyster seedling harvesting.

The front and rear sides of the ship are equipped with lifting frames; the front lifting frame is provided with a toothed meshing guide wheel, and the rear lifting frame is provided with a grooved guide wheel, and the lower rear of the grooved guide wheel is provided with a rope lifting device; the toothed meshing guide wheel includes an upper gear and a lower gear meshed with each other, the upper gear is coaxially fixed with the upper gear wheel, and the lower gear is coaxially fixed with the lower gear wheel; the tooth ends of the upper gear wheel and the lower gear wheel respectively have grooves for limiting the longline, and when the upper and lower gear wheels mesh with each other, the longline is clamped in the groove, so that the longline It is concave and convex in the groove; the outer sides of the upper gear and the lower gear are hinged by a box hinge, and the other side is locked and fixed by a locking pin; the conveying equipment is a rotating mechanism, which lifts the seedling rope and runs synchronously with the longline when conveying oysters, so that the oysters avoid colliding with the side of the ship; although the patent has low manpower consumption, high work efficiency, economy and safety, and simple installation during the entire layout and harvesting process, it is suitable for small and medium-sized oyster and caged shellfish farmers; but during use, it is easy for the equipment to get stuck. Specifically, the rope on the oyster string is easy to be entangled in the toothed meshing guide wheel and the grooved guide wheel, causing the equipment to stagnate and fail to work normally due to the entanglement of the rope. Summary of the invention:

[0008] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a ship-borne offshore oyster seedling harvesting equipment, which has a reasonable design and helps to avoid the entanglement of the ropes attached to the oyster seedlings, causing the equipment to be unable to operate normally.

[0009] The utility model is a ship-borne offshore oyster seed harvesting equipment, which is characterized by comprising a hull and a mounting frame fixedly arranged on the bow end of the hull, wherein the mounting frame is provided with an inclined conveyor belt, the lower end of the conveyor belt is immersed in the sea level and is lower than the bottom of the oyster seed to be harvested, and the upper end of the conveyor belt extends into the hull, and the conveyor belt is provided with a plurality of receiving hoppers for receiving oyster seed at intervals along its length direction, and the mounting frame is also provided with a rope cutter for cutting the rope connecting the oyster seed.

[0024] Figure 5 It is a top view of the receiving hopper;

[0025] Figure 6 yes Figure 5 sectional view. Specific implementation method:

[0027] The ship-borne offshore oyster seed harvesting equipment of the present invention includes a hull 1 and a mounting frame 2 fixedly arranged on the bow end of the hull 1. The hull 1 can be driven by an engine or an electric motor. The mounting frame 2 is a mounting rack and is installed on the bow end of the hull 1. Of course, it can also be installed on the side or the tail.

[0028] The mounting frame 2 is provided with an inclined conveyor belt 3 (which can be a belt or chain conveyor, and the conveyor belt 3 can be driven by a motor). The lower end of the conveyor belt 3 is immersed in the sea level and lower than the bottom of the oyster seedlings 4 to be harvested, and the upper end of the conveyor belt 3 extends into the hull. The conveyor belt 3 is provided with a plurality of receiving hoppers 5 for receiving oyster seedlings at intervals along its length direction. The length direction of the receiving hopper is the width direction of the conveyor belt 3. The mounting frame 2 is also provided with a rope cutter 6 for cutting the rope connecting the oyster seedlings. The rope cutter can be an electric saw. The mounting frame 2 is provided with a guide plate 24. The first end of the guide plate is connected to the discharge end of the conveyor belt, and the second end of the guide plate passes into the hull.

[0029] During operation, the hull 1 is driven by internal power to travel on the sea to the oyster seed breeding area, and the ropes attached to the oyster seed are cut by the cutting machine 6 submerged below the sea level (the oyster seed is attached to the ropes, which are suspended under the buoy or floating boat). The cut oyster seed ropes fall into the receiving hopper. As the conveyor belt runs, the receiving hopper pours the oyster seed ropes into the hull through the guide plate 24.

[0030] In this application, since the rope falls into the receiving hopper 5 after cutting, the possibility of the oyster seedling rope being entangled in the equipment and causing the equipment to stagnate is reduced; that is, it is helpful to avoid the rope attached to the oyster seedlings being entangled and causing the equipment to be unable to operate normally.

[0031] The mounting frame 2 includes side frames 7 provided on both sides of the bow end and a connecting rod 8 connected between the two side frames. The side frame 7 includes a rectangular frame 9 and a triangular frame 10 adjacent to the side of the rectangular frame. The rectangular frame 9 and the triangular frame 10 are both formed by welding square steel. The connecting rod 8 is also made of square steel. The diagonal braces 11 parallel to the hypotenuse of the triangular frame are provided at the diagonal corners of the rectangular frame 9. The diagonal braces 11 are also made of square steel. The upper side bars of the rectangular frame 9 are locked and fixed to the upper surface of the bow end by bolts 12. The mounting frame 2 constructed with the above structure is stable and reliable.

[0032] A support block 13 for supporting the mounting frame 2 is provided on the hull below the rectangular frame. The support block 13 is made of square steel and is welded and fixed along the width direction of the hull.

[0033] The two corners of the triangular frame 10 are protruding with mounting columns 14 for installing the conveyor belt roller. The mounting columns 14 are also made of square steel. The first ends are welded to the two corners of the triangular frame 10, and the second ends are connected to the roller (the roller is driven to rotate by the output shaft of the motor) for installing the conveyor belt 3.

[0034] The receiving hopper 5 includes two first rectangular plates 15 welded to form a right angle, a second rectangular plate 16 and a triangular side plate 17 connected to the two side edges (i.e., one end of the short side) of the first rectangular plate and the second rectangular plate. The first rectangular plate 15 is fixed on the surface of the conveyor belt 3, the second rectangular plate 16 and the triangular side plate 17 are both perpendicular to the surface of the conveyor belt 3, and there is a leakage hole 25 on the second rectangular plate 16. After the rope of the oyster seedlings is cut off, it falls into the receiving hopper 5, and the seawater leaks out through the leakage hole 25. Only the oyster seedling rope remains in the receiving hopper 5.

[0035] The electric saw machine is installed on the rope cutting machine mounting frame 18, and the rope cutting machine mounting frame includes a first side frame 19, a second side frame 20 and a guide rail 21 connected between the first side frame and the second side frame. The electric saw machine is slidably connected to the guide rail. The electric saw machine is moved in the length direction of the guide rail by manually pushing the electric saw machine, or driven by a screw nut mechanism to slide along the guide rail in the length direction. Since the oyster seedling ropes are placed in a matrix and suspended on the floating body, multiple oyster seedling ropes (corresponding to multiple ropes in the length direction of the guide rail 21) can be cut at one time by sliding the electric saw machine along the guide rail. The first side frame and the second side frame both include straight side bars 22 and longitudinal side bars 23 installed on the triangular frame. The straight side bars and the longitudinal side bars are vertically connected and fixed, and the straight side bars and the longitudinal side bars are respectively vertically connected to the two right-angled sides of the triangular frame.

[0036] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
