TECHNICAL FIELD

[0001] The present application relates to the field of marine products, in particular to the oyster harvesting technology field, specifically refers to a kind of special mechanized harvesting and sorting equipment for horizontal oyster culture and its use method. BACKGROUND

[0002] Artificial culture of oysters is usually carried out in suitable environments, such as sea areas with smooth tidal current and abundant bait. The choice of raft culture varies depending on the oyster variety. The oyster prefers lower salinity estuary, while the Dalian Bay oyster requires higher salinity areas away from the estuary. The Pacific oyster and the folded oyster are between the two.

[0003] Rope culture is suitable for oysters with fixed shells. Oyster larvae can be strung on ropes or polyethylene ropes and hung on raft frames or floating rafts. Net cage culture is to put oyster larvae into scallop net cages and hang them in the sea.

[0004] Beach seeding selects small waves and smooth tidal current in inner bays, and the bottom is preferably sandy or muddy. The seeding season is generally from mid-March to mid-April. The seeding method includes dry and wet seeding, and the seeding density is adjusted according to the quality of the beach.

[0005] When oysters and shrimps are mixed, mud or sandy mud bottom shrimp ponds are selected, and water depth and water exchange rate, as well as seeding density and time are considered. Oyster larvae and prawns need to ensure their own growth space.

[0006] Currently, the oyster culture mode in Fujian is horizontal, that is, oysters are cultured by horizontal ropes. This culture method uses raft frames, which mainly consist of anchors, long ropes, horizontal ropes, buoys and ropes. The anchor is fixed at the two ends of the long rope and sinks into the seabed. Along the main rope, every certain distance is connected with a buoy through a rope, and the buoy floats on the sea surface to arrange several main ropes side by side under the sea surface. The horizontal rope is tied between the adjacent two main ropes at certain intervals, and the oysters are attached to it. The structure of the culture frame becomes a horizontal rope culture raft, which makes the oysters attach to the seed rope. When the oysters are harvested, the seed rope and oysters are fished from the sea to the ship using the harvesting device, and then the oysters are removed from the seed rope. However, the current method is low in efficiency, resulting in low oyster harvesting efficiency. SUMMARY

[0007] The present application provides a kind of special mechanized harvesting and sorting equipment for horizontal oyster culture and its use method, which removes oysters from seed rope using sorting equipment, thereby improving oyster harvesting efficiency.

[0008] The application is realized by the technical scheme as follows: a special mechanical collection and sorting device for cross-cultivated oysters, comprising a frame, a rotating disc shaft-connected to the frame, and a pull plate arranged on the circumferential surface of the rotating disc, wherein a groove for hooking a seed rope is arranged on the pull plate, and the frame is further provided with a feeding frame, wherein a through hole for the pull plate to pass through is arranged on the feeding frame, and the width of the through hole and the groove is smaller than the size of the oyster.

[0009] In use, the seed rope is placed on the feeding frame, and then the rotating disc is driven to rotate, the pull plate is driven by the rotating disc to pass through the through hole from bottom to top, in the process of passing through, the seed rope falls into the groove, and is driven by the pull plate to rotate along with the pull plate, but since the width of the groove is smaller than the size of the oyster, the oyster is blocked by the feeding frame from rotating along with the seed rope when passing through the through hole and leaving the feeding frame, so that the oyster and the seed rope are separated, and the oyster is quickly collected.

[0010] Preferably, the groove penetrates the pull plate along the axial direction of the rotating disc, and the groove wall is an inclined arc surface.

[0011] The preferred scheme is provided with an inclined arc surface, which facilitates the seed rope to fall into the groove along the arc surface during the rotation of the pull plate.

[0012] Preferably, a gear shaft-connected in the pull plate is arranged between the rotating disc and the groove and extends into the groove.

[0013] In use, the seed rope rotates clockwise along with the rotating disc, the groove forms a counterclockwise pulling force on the seed rope which is tangent to the rotating disc, the pulling force makes the seed rope fall along an arc line onto the gear, the gear rotates counterclockwise along with the seed rope, and forms a stable and continuous force structure with the pull plate, and the teeth of the gear and the pull plate together fix the oyster seed rope.

[0014] Preferably, a rotating cutter extending to the groove to cut the seed rope is arranged on the frame and located on the rotating path of the groove.

[0015] The preferred scheme is provided with a rotating cutter, when the pull plate drives the seed rope to pass through the rotating cutter, the rotating cutter cuts the seed rope, and the seed rope falls off from the groove, so that the seed rope is dropped.

[0016] Preferably, a circumferentially closed ring groove is arranged on the circumferential surface of the gear, and the rotating cutter extends into the ring groove.

[0017] The preferred scheme is provided with a ring groove, so that the rotating cutter can be inserted into the ring groove when cutting the seed rope, thereby ensuring that the seed rope is cut while avoiding interference between the rotating cutter and the gear.

[0018] Preferably, two arc-shaped baffles are arranged below the rotating disc along the axial direction of the rotating disc, the rotating disc is located between the two arc-shaped baffles, the front end of the arc-shaped baffles extends forward and is fixed on the end face of the rotating disc, and the rear end of the arc-shaped baffles is located behind the rotating disc and is connected to the frame body.

[0019] When the seedling rope is driven to rotate by the seedling rope pull plate and passes through the arc-shaped baffles, the seedling rope rotates along the bottom surface of the arc-shaped baffles under the guidance of the arc-shaped baffles due to the fact that the front end of the arc-shaped baffles is fixed on the end face of the rotating disc, and the seedling rope falls from below the arc-shaped baffles after being cut by the rotating knife, so that the seedling rope is separated from the rotating disc by the baffles, thereby avoiding that the seedling rope is wound on the rotating disc due to being too long.

[0020] Preferably, the feeding frame comprises a stripping frame for blocking oysters, a supporting frame for supporting oysters and seedling ropes, and a conveying belt located on both sides of the rotating disc, a chute that slopes downward to above the conveying belt is connected to the supporting frame, the perforations pass through the stripping frame and the supporting frame, the bottom plate of the frame body is detachably connected to the hull, and the supporting frame and the conveying belt are connected to the bottom plate.

[0021] The stripping frame is arranged to facilitate blocking of oysters, the supporting frame is arranged to facilitate placement of seedling ropes, and the chute is arranged to facilitate sliding of oysters to both sides, thereby facilitating collection of oysters, and the bottom plate is arranged to facilitate mounting of the frame body on the hull.

[0022] Preferably, a guide plate that is located directly below the rotating knife and slopes to one side is further arranged on the support frame, and a limiting plate is further fixed on the top surface of the guide plate.

[0023] When the seedling rope is cut off by the rotating knife, the seedling rope falls on the guide plate and rolls to one side under the guidance of the guide plate, thereby facilitating collection of the seedling rope.

[0024] Preferably, ring teeth are arranged on the end face of the rotating disc, a motor is arranged on the frame body, and a driving tooth that cooperates with the ring teeth is connected to the output shaft of the motor.

[0025] The driving tooth and the ring teeth are arranged to facilitate rotation of the rotating disc.

[0026] The use method of the mechanical collection and sorting device special for horizontal culture oysters comprises the following steps: detachably mounting the frame body to a ship, collecting the horizontal rope cultured oysters and seed ropes to the ship by using the collection device on the ship, laying the hanging seed rope on the support frame, aligning the middle part of the seed rope with the rotating disc, rotating the rotating disc, and passing the pull plate from below to above through the perforation. When the pull plate penetrates the support frame, the seed rope falls into the recess under the guidance of the two arc slot walls of the recess, and falls onto the gear. Meanwhile, the gear rotates, and the seed rope rotates clockwise with the rotating disc. The recess forms a pulling force in the counterclockwise direction of the tangent line of the rotating disc on the seed rope. The pulling force makes the seed rope fall onto the gear along the arc, and the gear rotates counterclockwise with the seed rope, thereby forming a stable and continuous force structure with the pull plate. The teeth of the gear and the pull plate together fix the oyster seed rope. The rotating disc drives the pull plate to rotate clockwise, and the oyster is blocked by the pulling-off frame after the pull plate passes through the pulling-off frame. Therefore, with the continuous rotation of the rotating disc, the oyster falls off from the seed rope under the block of the pulling-off frame. The separated oyster falls into the chute and then falls onto the conveying belt from the chute for conveying.

[0027] The rotating disc continues to rotate, and the seed rope is combed and guided when passing through the blocking ring, so that the seed rope is away from the rotating disc, thereby avoiding the winding of the seed rope on the rotating disc. When the pull plate rotates and passes through the rotating knife, the rotating knife cuts the pull rope, and the pull rope falls off from the gear.

[0028] The beneficial effects of the present application are as follows: the seed rope is placed on the feeding frame, and then the rotating disc is driven to rotate. The rotating disc drives the pull plate to pass through the perforation from below to above. In the passing process, the seed rope falls into the recess. Under the driving of the pull plate, the seed rope rotates with the pull plate. However, since the width of the recess is smaller than the size of the oyster, the oyster is blocked by the feeding frame when passing through the perforation and leaving the feeding frame, so that the oyster and the seed rope are separated, thereby realizing the rapid collection of oysters.
