Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-4, a stichopus japonicus planktonic larva breeding device, comprising two cross bars 1, wherein one side of each of the two cross bars 1 is respectively connected with two first ejector rods 2 and two second ejector rods 3 through threads, the two first ejector rods 2 are respectively sleeved on the outer walls of the two second ejector rods 3 in a sliding manner, one side of each of the two cross bars 1 is detachably connected with two sleeves 4 through screws, the inside of the sleeves 4 is respectively connected with a longitudinal rod 5 in a sliding manner, the top ends of the longitudinal rods 5 are respectively connected with a counterweight column 10 through threads, and the lower ends of the counterweight columns 10 are respectively and fixedly connected with a magnet ring 11. The outer walls of the lower parts of the longitudinal rods 5 are provided with openings, and a first rotating shaft 6 and a second rotating shaft 7 are movably connected between the openings of the front longitudinal rod 5 and the rear longitudinal rod 5 at the left side and the right side respectively; the outer wall of the first rotating shaft 6 is wound with a piece of mesh cloth 8 and is fixedly connected with one end of the mesh cloth 8, the other side of the mesh cloth 8 is fixedly connected with two hand ropes 9, and the other ends of the two hand ropes 9 are sequentially wound on the outer walls of the second rotating shaft 7 and the first rotating shaft 6 and extend to the upper part of the first ejector rod 2; one side of the grid cloth 8 is fixedly connected with a plurality of weighting pendants 12 which are arranged in two rows.

In this embodiment: two horizontal poles 1 are used for strideing and placing the ground at cultivating the pond edge, and make a plurality of sleeves 4 all arrange in and cultivate pond water level top, then can all connect the upper end at vertical pole 5 with a plurality of counter weight post 10, make a plurality of vertical poles 5 and first pivot 6 and second pivot 7 all sink under the action of gravity, sink to the counter weight post 10 butt and stop sinking when sleeve 4 top, magnet ring 11 adsorbs in the top of sleeve 4 this moment, guarantee that first pivot 6 and second pivot 7 are stable in aqueous. Then through pulling two hand ropes 9 for hand rope 9 drives first pivot 6 and rotates and net cloth 8 and expandes, net cloth 8 expandes the in-process by a plurality of weights that set up of its below and weighs pendant 12, drag downwards and form and fight the trough-shaped, then screw down a plurality of counter weight posts 10, under the buoyancy effect, first pivot 6 and second pivot 7 drive the net cloth 8 that expandes and rise, the in-process that rises slowly upwards pulls hand rope 9, prevent that 8 right sides of in-process net cloth from breaking away from second pivot 7, net cloth 8 can strain out surplus water and leave the high-quality stichopus japonicus larva of upper strata, reach the breeding purpose.

The first rotating shaft 6, the second rotating shaft 7 and the longitudinal rods 5 are all made of hollow stainless steel, buoyancy of the longitudinal rods in water is far larger than self gravity, the counterweight columns 10 are all made of solid iron, the sum of the gravity of the counterweight columns 10 is far larger than the maximum buoyancy of the first rotating shaft 6, the second rotating shaft 7 and the longitudinal rods 5 in water, and the self gravity of the weighted weights 12 is far larger than the maximum buoyancy in water. First pivot 6, second pivot 7 and a plurality of vertical pole 5 are hollow stainless steel and make, and its buoyancy in aqueous is far greater than self gravity, when can guaranteeing to screw down counter weight post 10 of a plurality of vertical poles 5 upper ends, first pivot 6 and second pivot 7 can drive net cloth 8 come-up to the surface of water under the buoyancy. The multiple counterweight columns 10 are made of solid iron, the sum of the gravity is far larger than the maximum buoyancy of the first rotating shaft 6, the second rotating shaft 7 and the multiple longitudinal rods 5 in water, and when the multiple counterweight columns 10 are installed at the upper ends of the longitudinal rods 5, the first rotating shaft 6 and the second rotating shaft 7 can slowly sink under the gravity of the multiple counterweight columns 10. The self gravity of the weighted weights 12 is far greater than the maximum buoyancy in water, so that the grid cloth 8 can form a bucket-shaped groove under the action of the gravity of the weighted weights 12 when being unfolded, and the bucket-shaped groove is used for containing young stichopus japonicus.

The outer walls of the two first ejector rods 2 are in threaded connection with fastening bolts 13, and the lower ends of the two fastening bolts 13 abut against the outer wall of the second ejector rod 3. Two first ejector pins 2 slide and cup joint at the outer wall of two second ejector pins 3, consequently the distance between two adjustable horizontal poles 1, and fastening bolt 13 can be used to fixed first ejector pin 2 and second ejector pin 3 and prevent its slip, and two horizontal poles 1 can not be close to when guaranteeing the pulling hand rope 9.

The outer walls of the two cross rods 1 are fixedly connected with two contact pins 14. The contact pins 14 can make the two cross bars 1 not contact with the ground and have a certain height, so that the operator can conveniently hold the two cross bars.

The outer walls of the two sleeves 4 on the left side are fixedly connected with a clamping ring 15, and the two hand ropes 9 penetrate through the clamping ring 15. The snap ring 15 is used for limiting the hand rope 9 and preventing the hand rope 9 from falling into water.

The periphery of the mesh cloth 8 is reinforced and sealed. The banding setting is all consolidated all around of net cloth 8, and its four sides are tight when can guaranteeing to drag net cloth 8 through hand rope 9, and sink under dragging of aggravating weight pendant 12 in the middle of net cloth 8.

The plurality of sleeves 4 are made of iron. The iron sleeve 4 ensures that the magnet ring 11 is firmly attached to its upper end face.

The outer walls of the first rotating shaft 6 and the second rotating shaft 7 are provided with a plurality of grooves matched with the hand ropes 9. The groove prevents the hand cord 9 from slipping down unintentionally in the front-rear direction of the first and second shafts 6 and 7.

The working principle is as follows:

firstly, stopping oxygen in the cultivation pool and standing for about one hour, irradiating the pool surface by a fluorescent lamp after all the high-quality stichopus japonicus larvae float upwards to centralize the larvae, then enabling an operator to stretch and place the two cross rods 1 on the ground at the edge of the cultivation pool, and enabling the plurality of sleeves 4 to be placed above the water surface of the cultivation pool. Then can all connect a plurality of counter weight posts 10 in the upper end of vertical pole 5, make a plurality of vertical poles 5 all sink with first pivot 6 and second pivot 7 under the action of gravity, sink to the counter weight post 10 and stop sinking when butt in sleeve 4 top, magnet ring 11 adsorbs the top at this moment in sleeve 4, guarantees that first pivot 6 and second pivot 7 are stable in aqueous. Then through pulling two hand ropes 9 for hand rope 9 drives first pivot 6 and rotates and net cloth 8 expandes, and net cloth 8 expandes the in-process by a plurality of weights of setting of its below pendant 12, drags downwards and forms the fill trough-shaped. Then a plurality of counter weight columns 10 are screwed off, under the action of buoyancy, the first rotating shaft 6 and the second rotating shaft 7 drive the expanded grid cloth 8 to ascend, the hand rope 9 is slowly pulled upwards in the ascending process, the right side of the grid cloth 8 is prevented from being separated from the second rotating shaft 7 in the ascending process, the grid cloth 8 can filter out excessive water to leave high-quality stichopus japonicus larvae on the upper layer, and the high-quality stichopus japonicus larvae are transferred to other prepared culture ponds, so that the breeding purpose is achieved.
