[0001] For sea cucumbers, the purpose of pond transfer operation is to effectively remove organic matters, residual baits and excrements at the bottom of the pond, avoid the corruption of them to produce harmful substances such as ammonia nitrogen and sulfide, so as to improve the water quality and ensure the normal growth of sea cucumbers.

[0002] The existing pond transfer methods are mainly manual pond transfer and semi-automatic pond transfer devices. The semi-automatic pond transfer device mainly consists of a mobile track and a frame system, a lifting system and a fixing mechanism. The fixing mechanism includes a tray, a connecting rope and a hook. The hook is used to hook up the sea cucumber breeding bag and drive it to move to the target position. However, during the process of the connecting rope driving the hook to fall, since the hook is in a free swinging state and the bending angle of the hook is in a fixed state, the hook cannot smoothly hook the breeding bag, resulting in the unhooked breeding bag being difficult to be smoothly lifted, causing low overall lifting efficiency and requiring manual adjustment by the operator, thus affecting the pond transfer efficiency. Summary of the Invention

It also includes a plurality of first frames, and a plurality of the first frames are fixedly connected to the lower side of the lifting frame. The first frame is rotatably connected to a fixed rod. When the first frame and the corresponding fixed rod are in a vertical state, the two together form a hook for driving the breeding bag to move. A control mechanism for adjusting the positions of all the fixed rods is arranged on the lifting frame to make the first frame and the corresponding fixed rod form a hook.

[0005] Further, an inclined surface is arranged on one side of the fixed rod.

[0008] Furthermore, a hand lever is slidably connected to the landing gear, and an elastic member is provided between the two, and the hand lever is used to limit the hand crank member.

[0009] Furthermore, it also includes: There are several pressing pieces, which are respectively fixed between two adjacent third frames, and the pressing pieces are used to fix the breeding bags.

[0010] Furthermore, it also includes: A receiving mechanism is arranged on the mobile frame and is used to cover the lower sides of all the breeding bags. The receiving mechanism includes: There are two electric shafts, which are respectively installed on both sides of the mobile frame; There are two interception plates, which are respectively fixed to adjacent electric shafts.

[0014] The beneficial effect is that the present invention converts the first frame and the fixing rod from a flush state to a vertical state, so that the first frame and the fixing rod form a hook, which makes it easy to insert the fixing rod into the hanging ring of the breeding bag to ensure that the breeding bag is hooked, without the need for the operator to confirm in sequence, reducing the operator's operating steps and improving the efficiency of pond inversion.

[0015] The present invention limits the hand-cranked part by means of a hand-pulled rod, so that the hand-cranked part cannot be deflected, thereby preventing the fixing rod from rotating, thereby ensuring the stability of the breeding bag during movement.

Detailed implementation manners

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Embodiment 1

[0020] In this embodiment, a device for transferring sea cucumber fry for breeding is specifically proposed, as shown in Figures 1 - 7 , Figure 11 and Figure 12As shown in the figure, it includes a moving frame 1. A driving module 2 is installed on the moving frame 1. The driving module 2 is composed of a driving motor and four winches. Four electric wheels are installed on the moving frame 1. The electric wheels are used to drive the moving frame 1 to move on the breeding pond 101, so as to change the position of the landing gear 3. The moving frame 1 is provided with a landing gear 3. The steel wire ropes of the winches on the driving module 2 are fixedly connected to the edge of the landing gear 3. The driving module 2 drives the landing gear 3 to move up and down through the steel wire ropes of its winches. A number of first frames 5 are fixedly connected to the lower side of the landing gear 3. The first frames 5 are rotatably connected to fixed rods 6. The rotation position of the first frames 5 and the fixed rods 6 is located in the middle of the fixed rods 6. The fixed rods 6 are composed of L-shaped rods and wedge-shaped blocks. The wedge-shaped blocks are located on the lower side of the L-shaped rods. When the first frames 5 and the corresponding fixed rods 6 are in a vertical state, they jointly form a hook for driving the breeding bag 102 to move. A regulating mechanism for adjusting the positions of all the fixed rods 6 is provided on the landing gear 3 to make the first frames 5 and the corresponding fixed rods 6 form hooks; an inclined surface is provided on the lower side of the fixed rods 6, and this inclined surface is used to guide the fixed rods 6 to facilitate the movement of the fixed rods 6 to the side of the breeding bag 102 (such as Figure 11 ); a number of protrusions are provided on the L-shaped rod parts of the fixed rods 6. The protrusions are made of rubber material and are located between the rotation position of the first frames 5 and the fixed rods 6 and the wedge-shaped block parts of the fixed rods 6 to ensure the stability during the lifting of the breeding bag 102. The above-mentioned breeding pond 101 and breeding bag 102 are both existing structures, and two lifting rings are provided on the upper side of the breeding bag 102.

[0021] Such as Figures 1 - 7 、 Figure 11 and Figure 12 As shown, the regulating mechanism includes: a hand crank member 201, which is rotatably connected to the landing gear 3 in a limited way. Initially, the state of the hand crank member 201 is as shown in Figure 4 . The hand crank member 201 is composed of a T-shaped rod and a straight frame. The T-shaped rod is rotatably connected to the landing gear 3, and the T-shaped rod and the straight frame are rotatably connected. A chute is provided on the upper part of the landing gear 3, and the T-shaped rod is located in the chute of the landing gear 3 and slides; a driving frame 202, which is hinged to the straight frame of the hand crank member 201; a number of second frames 203, all of which are rotatably connected to the driving frame 202. A number of convex columns are provided on the landing gear 3, and the convex columns correspond to the second frames 203 one by one, and the second frames 203 are slidably connected to the adjacent convex columns on the landing gear 3; a number of third frames 204, the number of which is the same as the number of the fixed rods 6, are fixedly connected to the lower sides of the second frames 203 and are respectively rotatably connected to the upper sides of the adjacent fixed rods 6.

[0022] Such as Figure 4 and Figure 8As shown in the figure, a hand lever 301 is slidably connected to the landing gear 3, and an elastic member is provided between the two. The elastic member is a spring, which is used to drive the hand lever 301 to reset. The hand lever 301 is composed of a grip, a round rod and a limit block. The limit block of the hand lever 301 is used to limit the hand crank member 201.

[0023] The specific operation of a pond-changing device for breeding sea cucumber fry in this embodiment is as follows: When pond-changing operation is required, the operator controls the movement of the moving frame 1 through all the electric wheels. When the moving frame 1 moves to the designated position, the electric wheels stop working. Subsequently, the driving module 2 is activated, and the driving module 2 drives the landing gear 3 to move downward. The landing gear 3 drives the fixed rod 6 to move synchronously through the first frame 5. During this process, the first frame 5 is flush with the adjacent fixed rod 6 (as Figure 6 shown in the figure). The landing gear 3 drives the hand crank member 201 to move downward, and the hand crank member 201 drives the driving frame 202 and the second frame 203 to move downward synchronously. The driving frame 202 drives the third frame 204 to rotate. During this process, the states of the driving frame 202 and the second frame 203, the states of the third frame 204 and the first frame 5, and the states of the second frame 203 and the landing gear 3 are all as Figure 6 shown in the figure.

[0024] As all the fixed rods 6 move downward until the wedge-shaped block part of the fixed rod 6 moves to correspond to the hanging ring of the breeding bag 102 (as Figure 11 shown in the figure), the driving module 2 stops working. Subsequently, the operator pulls the hand lever 301 to the left, and the elastic member on the hand lever 301 is compressed. When the limit block of the hand lever 301 loses contact with the hand crank member 201, the operator pushes the hand crank member 201 forward, and the hand crank member 201 drives the driving frame 202 to move forward.

[0025] During the process of the driving frame 202 moving forward, the driving frame 202 drives the second frame 203 and the third frame 204 to move. The third frame 204 drives the fixed rod 6 to move, causing the fixed rod 6 to rotate along the first frame 5. At the same time, the fixed rod 6 drives the driving frame 202 to move downward through the third frame 204, and the second frame 203 slides relative to the landing gear 3.

[0026] When the hand crank member 201 cannot move forward, that is, when the hand crank member 201 contacts the front side of the chute on the landing gear 3, the operator releases the hand lever 301. The hand lever 301 moves to the right and resets under the action of the elastic member thereon, and is located at the rear side of the hand crank member 201, thereby limiting the hand crank member 201.

[0027] During the process of the fixed rod 6 rotating along the first frame 5, the wedge-shaped block part of the fixed rod 6 penetrates into the hanging ring of the breeding bag 102 (as Figure 12As shown in the figure, when the hand-cranked part 201 stops rotating, the driving frame 202 stops moving, that is, the fixed rod 6 stops moving. At this time, the first frame 5 and the fixed rod 6 are in a perpendicular state to each other (as Figure 12 shown). By converting the first frame 5 and the fixed rod 6 from a flush state to a perpendicular state, a hook is formed between the first frame 5 and the fixed rod 6, which facilitates the insertion of the fixed rod 6 into the hanging ring of the breeding bag 102, ensuring that the breeding bag 102 is hooked. There is no need for the operator to determine one by one, reducing the operator's operation steps and improving the efficiency of pond turnover.

[0028] After the first frame 5 and the fixed rod 6 are perpendicular to each other, the operator activates the driving module 2. The driving module 2 drives all the first frames 5 and all the fixed rods 6 to move upward through the landing gear 3. The fixed rod 6 drives the corresponding breeding bag 102 to move upward until the breeding bag 102 rises to the specified height (as Figure 2 shown). The driving module 2 stops working. Subsequently, the operator activates the electric wheel, and the electric wheel drives the moving frame 1 to move horizontally, moving the landing gear 3 and all the breeding bags 102 thereon above the specified breeding pond 101. Then, the operator uses the driving module 2 to lower all the breeding bags 102 into the specified breeding pond 101.

[0029] During the process of the fixed rod 6 driving the breeding bag 102 to move, the hand-pulling rod 301 limits the hand-cranked part 201, making the hand-cranked part 201 unable to deflect, so that the fixed rod 6 cannot rotate, ensuring the stability of the breeding bag 102 during the moving process.

[0030] When the breeding bag 102 contacts the specified breeding pond 101, the operator pulls the hand-pulling rod 301 to the left again (the elastic part is compressed) until the hand-pulling rod 301 loses contact with the hand-cranked part 201. The operator pulls the hand-cranked part 201 backward. The hand-cranked part 201 drives the driving frame 202 to move backward. The driving frame 202 drives the second frame 203 and the third frame 204 to move, so that the fixed rod 6 rotates in the opposite direction along the first frame 5 until the hand-cranked part 201 cannot move. The first frame 5 and the fixed rod 6 return to the initial flush state. At the same time, the hand-pulling rod 301 resets under the action of the elastic part and limits the hand-cranked part 201 again. Then, the operator drives all the fixed rods 6 to reset through the driving module 2. In this way, a single pond turnover operation is completed. After that, the operator repeats the above process to replace the breeding bags 102 in the remaining breeding ponds 101. Embodiment 2

[0031] This embodiment discloses a pond turnover device for sea cucumber seed breeding. On the basis of Embodiment 1, it also has the effect of fixing the corresponding breeding bag 102.

[0032] As Figures 4 - 7 、 Figure 11 and Figure 12As shown, it also includes: a plurality of pressing members 401, which are respectively fixed between two adjacent third frames 204, and the pressing member 401 is composed of a straight rod and an L-shaped plate, and the straight rod part is fixed between two adjacent third frames 204. The pressing member 401 is used to fix the breeding bag 102. Initially, the pressing member 401 does not contact the breeding bag 102 (such as Figure 11 As shown in the figure, during the downward movement of the third frame 204, the third frame 204 drives the adjacent pressing member 401 to move until the third frame 204 stops moving (based on the working principle of Example 1), and the lower side of the pressing member 401 contacts the upper side of the corresponding breeding bag 102 (as shown in the figure). Figure 12 As shown), the corresponding breeding bag 102 is pressed by the pressing piece 401, and the fixing rod 6 is used to pull the hanging ring on the breeding bag 102, so as to apply two opposite forces to the breeding bag 102, thereby improving the stability of the breeding bag 102 during movement, reducing the shaking of the breeding bag 102 during movement, and thus reducing the probability of stress response of the sea cucumber. Example 3

[0033] The present embodiment discloses a pond inverting device for breeding sea cucumber seedlings. On the basis of Embodiment 1, it also has the effect of shielding the lower sides of all breeding bags 102. In the process of driving all breeding bags 102 to move, if sea cucumbers fall from the breeding bags 102, the existing pond inverting device cannot handle the fallen sea cucumbers, resulting in squeezing of the fallen sea cucumbers when the breeding bags 102 fall.

[0034] like Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown, it also includes: a receiving mechanism, which is arranged on the mobile frame 1 and is used to cover the lower side of all the breeding bags 102. The receiving mechanism includes: an electric shaft 501, which has two, which are respectively installed on the left and right sides of the mobile frame 1. The electric shaft 501 is an existing structure, and its internal parts are not specifically shown. It is only an example in the figure; there are two interception plates 502, which are respectively fixed to adjacent electric shafts 501. A plurality of through holes are set on the interception plates 502. Initially, the two interception plates 502 are in an open state (such as Figure 3 As shown), when the two interception plates 502 are aligned (as shown Figure 9As shown in the figure, the two intercepting plates 502 are spliced to form a complete plane and are located below the breeding pockets 102 to prevent sea cucumbers from falling into the breeding pond 101; a plurality of shielding strips 601 are fixedly connected to the intercepting plates 502, and the cross section of the shielding strips 601 is hook-shaped. The plurality of shielding strips 601 divide the intercepting plates 502 into several parts. At the same time, the number of the shielding strips 601 corresponds to the number of columns of the breeding pockets 102, and each part of the intercepting plates 502 corresponds to one column of the breeding pockets 102; all the shielding strips 601 are provided with inclined surfaces, and the inclined surfaces are used to guide the falling sea cucumbers.

[0035] Based on the working principle of Embodiment 1, during the process of the driving module 2 driving all the fixing rods 6 to move downward, the two intercepting plates 502 are in an open state (as Figure 3 shown), and the two intercepting plates 502 do not affect the movement of the fixing rods 6.

[0036] When all the fixing rods 6 drive the corresponding breeding pockets 102 to move upward to a specified height (as Figure 2 shown), the operator turns on the two electric shafts 501, and the electric shafts 501 drive the adjacent intercepting plates 502 to rotate, so that the two intercepting plates 502 rotate to an aligned state (as Figure 9 shown). The two intercepting plates 502 are spliced into a whole, and the two intercepting plates 502 are both located below all the breeding pockets 102. At this time, the two electric shafts 501 are turned off.

[0037] After the breeding pockets 102 move upward to a specified height, the breeding pockets 102 start to move horizontally. During this process, the two intercepting plates 502 shield the lower sides of the breeding pockets 102. When the sea cucumbers fall from the breeding pockets 102, the intercepting plates 502 intercept the sea cucumbers, so that the sea cucumbers fall onto the intercepting plates 502.

[0038] When the falling sea cucumbers come into contact with the shielding strips 601, the inclined surfaces of the shielding strips 601 guide the sea cucumbers so that they fall onto the corresponding intercepting plates 502.

[0039] After the breeding pockets 102 move to above the specified breeding pond 101, the operator controls the two electric shafts 501 again to make the two intercepting plates 502 swing and return to the initial position. During the swinging process of the intercepting plates 502, the sea cucumbers roll on the intercepting plates 502 and are intercepted by the adjacent shielding strips 601. Until the intercepting plates 502 are reset, the sea cucumbers on the intercepting plates 502 are respectively located on the adjacent shielding strips 601. Then the operator repeats the working principle of Embodiment 1 to move all the breeding pockets 102 into the specified breeding pond 101 and complete the pond-changing operation.

[0040] After all the fixing rods 6 move upward to the initial position, the operator collects the sea cucumbers piled up on all the shielding strips 601. Embodiment 4

[0041] This embodiment discloses a pond-changing device for sea cucumber fry breeding. On the basis of Embodiment 3, it also has the effect of flushing all the breeding pockets 102.

[0042] As Figure 2 , Figure 3 , Figure 9 and Figure 10 shown, it further includes: a flushing mechanism arranged on two intercepting plates 502 for flushing the breeding pockets 102. The flushing mechanism includes: a water supply system 701 installed on the moving frame 1. The water supply system 701 is composed of a water tank and a water pump, and the water inlet of the water pump is communicated with the water tank. Only for illustration in the figure, the internal composition of the water supply system 701 is not shown in detail; two connecting pipes 702 are both fixedly connected to the moving frame 1 and are both communicated with the water outlet of the water pump in the water supply system 701. A number of rotary nozzles 703 are installed on the shielding strip 601. The rotary nozzles 703 are of existing structures and adopt the existing centrifugal nozzle structure, and realize rotary spraying through water flow driving. The connecting pipe 702 passes through the adjacent shielding strips 601, and all the rotary nozzles 703 on the same intercepting plate 502 are communicated with the corresponding connecting pipe 702.

[0043] Based on the working principle of Embodiment 3, when the two intercepting plates 502 are in a flush state, the operator turns on the water supply system 701. The water supply system 701 pumps water into the connecting pipe 702. Subsequently, the water flows into the corresponding rotary nozzles 703 through the connecting pipe 702 and is sprayed out through the rotary nozzles 703. The sprayed water flushes the adjacent breeding pockets 102, reducing the impurities attached to the breeding pockets 102 and providing a better environment for the subsequent growth of sea cucumbers.

[0044] When the two intercepting plates 502 are in a separated state, the water supply system 701 is turned off to stop flushing the breeding pockets 102. Subsequently, the operator regularly replenishes water in the water tank of the water supply system 701.

[0045] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
