Description

Technical Field

[0001] This invention patent belongs to marine aquaculture equipment, and relates to a mechanical device used in the process of transferring sea cucumber seedlings to ponds during sea cucumber seedling cultivation. Background Technology

[0002] During the sea cucumber seedling cultivation process, the seedling ponds become polluted due to the excrement produced by the sea cucumber seedlings' metabolism, the death of seedlings, the accumulation of rotten feed, and the accumulation of various impurities and toxic substances carried by seawater. This leads to a significant increase in the disease and mortality rates of the sea cucumber seedlings. Therefore, it is necessary to transfer the sea cucumber seedlings to a clean seedling pond to ensure their healthy growth.

[0003] Currently, sea cucumber transfer mainly relies on manual harvesting or siphoning to transfer seedlings to new nursery ponds. However, manual harvesting and siphoning are time-consuming, labor-intensive, and extremely inefficient, significantly increasing the mortality rate of sea cucumber seedlings, resulting in unsatisfactory transfer outcomes. Besides manual transfer, a few mechanical transfer devices exist, primarily gantry-type transfer equipment. However, this type of equipment is not only expensive but also has limitations regarding the available farming space. Additionally, some transfer machines require manual hooking of the seedling net cages, which is time-consuming, labor-intensive, and prone to inaccuracies. Summary of the Invention

[0004] This invention patent provides an automatic sea cucumber seedling transfer machine to solve the drawbacks of manual transfer and fill the gaps in general transfer machinery.

[0005] The technical solution of this invention patent:

[0006] An automatic sea cucumber seedling transfer machine is characterized by comprising: a main frame, a lifting unit, a moving unit, and a control unit.

[0007] The main frame consists of a first horizontal frame 1-1, a second horizontal frame 1-2, a first side frame 2-1, a second side frame 2-2, a first support frame 3-1, a second support frame 3-2, a third support frame 3-3, an L-shaped fixing plate 4, a load-bearing plate 5, and a load-bearing frame 29.

[0008] The lifting unit consists of a hook frame 6, a hook 7, a sliding plate 8, an auxiliary slider 9, a lifting frame 10, a vertically moving directional roller 11, a lifting ring 12, a lifting rope 13, a lifting pulley 14, a lifting motor 15, a winding reel 16, a servo motor 27, and a drive slider 30. The hook frame moves up and down under the drive of the lifting rope and the lifting pulley. Due to the presence of the guide rail on the support frame, the swaying of the hook frame in the front, back, left, and right during the up and down movement is limited, which improves the accuracy of picking and hanging and reduces the adverse effects of swaying on sea cucumber seedlings.

[0009] The moving unit consists of a moving motor 17, a speed reducer 18, a drive shaft 19, a driving sprocket 20, a chain 21, a driven sprocket 22, a driving wheel axle 23, a driven wheel axle 24, a driving wheel 25, and a driven wheel 28.

[0010] The control unit mainly includes a control box 26.

[0011] Furthermore, in the initial state, the angle between the hook and the vertical direction is 60°. When the hook frame reaches the designated position, the hook rotates 60° clockwise and becomes perpendicular to the horizontal direction. When the pool pouring work is finished, the hook rotates 60° counterclockwise and returns to the initial position.

[0012] This invention patent has the following advantages:

[0013] It reduces manual labor, lowers labor intensity, and improves work efficiency.

[0014] Not limited by site, it can be moved flexibly, with low cost, simple structure and easy operation, reducing the stimulation to sea cucumber seedlings and reducing the mortality rate.

[0015] It fills the gap in automated equipment in this field, improves the level of automation, and reduces breeding costs. Attached Figure Description

[0026] like Figures 1 to 7 As shown, an automatic sea cucumber seedling transfer machine mainly consists of a main frame, a lifting unit, a moving unit, and a control unit.

[0027] The main frame consists of a first horizontal frame 1-1, a second horizontal frame 1-2, a first side frame 2-1, a second side frame 2-2, a first support frame 3-1, a second support frame 3-2, a third support frame 3-3, an L-shaped fixing plate 4, a load-bearing plate 5, and a load-bearing frame 29; the lifting unit consists of a hook frame 6, a hook 7, a sliding plate 8, an auxiliary slider 9, a lifting frame 10, an up-and-down moving directional roller 11, a lifting ring 12, a lifting rope 13, a lifting pulley 14, a lifting motor 15, a winding reel 16, a servo motor 27, and a drive slider 30; the moving unit consists of a moving motor 17, a reduction reversing device 18, a transmission shaft 19, a drive sprocket 20, a chain 21, a driven sprocket 22, a drive wheel axle 23, a driven wheel axle 24, a drive wheel 25, and a driven wheel 28; the control unit mainly includes a control box 26.

[0028] The first and second crossbeams 1-1 and 1-2 in the main frame are both welded from two long channel steels and two short channel steels in the middle. Holes are opened at both ends and on the top surface of the crossbeams. The first and second crossbeams 1-1 and 1-2 are installed symmetrically. The first side frame 2-1 is installed on the two crossbeams, and the second side frame 2-2 is installed symmetrically with the first side frame 2-1. There are four L-shaped fixing plates 4 in the main frame, symmetrically installed at both ends of the first and second crossbeams 1-1 and 1-2, and bolted to the crossbeams. The outward-facing end face of the L-shaped fixing plate 4 overlaps with the inward-facing surface of the first and second side frames 2-1 and 2-2 and is welded together. The first support frame 3-1, second support frame 3-2, and third support frame 3-3 in the main frame have the same structure, all made of rectangular tubing, with two transverse... Two shorter rectangular tubes are welded between the rectangular tubes. A directional guide rail is welded to the inner surface of the vertical support leg of each support frame. Three “L”-shaped thin-walled plates are welded to the inward surfaces of the first side frame 2-1 and the second side frame 2-2 in the main frame. The first support frame 3-1, the second support frame 3-2, and the third support frame 3-3 are welded to the “L”-shaped thin-walled plates respectively. The load-bearing plate 5 is a rectangular steel plate with a thickness of 1mm. The load-bearing frame 29 is welded from rectangular tubes and is “H”-shaped. The load-bearing plate 5 has four bolt holes, which correspond one-to-one with the bolt holes on the four corners of the load-bearing frame. The load-bearing plate 5, the load-bearing frame 29, the first support frame 3-1, and the second support frame 3-2 are connected to each other with bolts. The order from top to bottom is load-bearing plate 5, load-bearing frame 29, first support frame 3-1, and second support frame 3-2.

[0029] The hook frame 6 in the lifting unit is made of aluminum alloy and features a hollow design to reduce weight. The hook frame 6 has holes for mounting the hooks 7. The main body of the hook 7 is a cylindrical tube, with six evenly welded cylindrical stainless steel strips. A groove is located at the right end of the hook 7 for mounting the auxiliary slider 9. Both the slider 8 and the auxiliary slider 9 are made of high-impact PS. The slider 8 is a rectangular thick plate with rounded corners at both ends to reduce material usage. Holes are evenly distributed on the slider 8. The auxiliary slider 9 is an egg-shaped thick plate, wider at the top and narrower at the bottom, with a circular hole at the top for mounting the auxiliary slider 9 to the slider 8. The two are connected by screws. The drive slider 30 is an egg-shaped thick plate with rounded corners at both ends. The upper end has a circular hole, which is connected to the slider 8 by screws. The lower end of the circular hole is connected to the servo motor 27, forming the active crank of the parallelogram mechanism. The lower end of the auxiliary slider 9 has a concave hole for connecting the auxiliary slider 9 and the hook 7. The concave protrusion of the auxiliary slider 9 is installed in the groove of the hook 7. The two ends of the hook 7 are equipped with elastic cylindrical pins. The servo motor 27 is fixed to the hook frame. The servo motor 27 drives the slider 9 to make translational movements through the drive slider 30. The winding reel consists of three wire grooves.

[0030] The lifting unit has three lifting frames 10, and their installation positions correspond to the support frame. The lifting frame 10 is "H" shaped and is welded from rectangular tubes. The lifting frame 10 is bolted to the hook frame. The vertical moving directional rollers 11 are respectively installed on the left and right end faces of the lifting frame 10. The vertical moving directional rollers 11 are bolted to the lifting frame 10. The vertical moving directional rollers 11 are placed in the directional guide rail of the support frame. Lifting rings 12 are welded to the two upper ends of the lifting frame 10. Lifting pulleys 14 are symmetrically installed on the support frame and bolted to each other. One end of the lifting rope 13 is fixed to the lifting ring 12, and the other end passes around the lifting pulley 14 and is fixed to the winding reel 16. The lifting motor 15 is fixed to the winding reel 16 on the load-bearing plate. The lifting motor 15 drives the winding reel 16 to rotate.

[0031] The mobile motor 17 in the mobile unit is fixedly connected to the first side frame 2-1. The output shaft of the mobile motor 17 is connected to the reducer 18. The transmission shaft is fixedly connected to the reducer 18 for transmitting power. The two ends of the transmission shaft 19 are respectively equipped with drive sprockets 20. The drive sprockets 20 are connected to the driven sprockets 22 through the chain 21. The drive wheel axle 23 is fixedly connected to the driven sprockets 22. The two drive wheels 25 are respectively connected to the first cross frame 1-1 and the second cross frame 1-2 through the drive wheel axle 23. The two driven wheels 28 are respectively connected to the first cross frame 1-1 and the second cross frame 1-2 through the driven wheel axle 24. The control box 26 in the control unit is fixedly connected to the load-bearing plate.

[0032] When the pool-turning operation begins, pressing the start switch activates the control box, initiating a command to activate the moving motor 17. Power is transmitted via the drive shaft 19 to the drive sprocket 20, which then transmits power to the driven sprockets 22 via the chain 21. The two driven sprockets 22 are fixedly connected to the axles 23 of the two drive sprockets. The two drive sprockets 25 drive the entire machine. When the pool-turning machine reaches the working pool, the control box 26 activates the moving motor 17, stopping it and activating the lifting motor 15. The vertically moving guide roller 11 slowly descends along the guide rail. When the hook frame 6 reaches the target position, the control box 26 activates the lifting motor 15, stopping it and activating the servo motor 27, which rotates the drive slider 30 60° clockwise. The sliding plate 8 is driven to move, and the sliding plate 8 drives the auxiliary slider 9 and hook 7 to rotate. The angle between the hook and the vertical direction becomes 0°, completing the hook's attachment of the net basket. The control box issues a command, and the lifting motor 15 starts working, raising the net basket to the upper surface away from the seedling pond. The lifting motor 15 stops working, and the moving motor 17 starts working, moving the net basket to the clean pond. The moving motor 17 stops working, and the lifting motor 15 starts working, slowly lowering the net basket to the bottom of the pond. The servo motor 27 drives the drive slider 30 to rotate counterclockwise by 60°. The drive slider 30 pulls the sliding plate 8, driving the auxiliary slider 9 and hook 7 to rotate back to their original positions. The lifting motor works, taking the hook frame 6 and hook 7 away, and the net basket transfer operation is completed.

[0033] This example automates the process of transferring sea cucumber seedlings to their ponds, reducing labor intensity, improving work efficiency, and is low in cost and simple in structure. It also reduces mechanical damage to the seedlings and lowers the mortality rate of sea cucumber seedlings caused by the transfer process.

[0034] Except for the technical features described in this specification, all other technologies are known to those skilled in the art.
