Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture devices, and in particular relates to a crab breeding device. Background Art

[0002] The main breeding mode of crabs is pond breeding. Although the total amount is large, there are problems such as backward pond facilities, low breeding survival rate, and low product added value, which restrict the development of the industry. Land-based individual crab breeding is one of the feasible ways to solve the above problems. By collecting sub-adult crabs from ponds and transferring them to individual breeding systems for separate breeding, it can not only prevent cannibalism and off-season marketing, but also produce high-value-added aquatic products such as soft-shell crabs.

[0003] Based on this, people have developed land-based single-body crab farming devices, such as the invention patent "Indoor three-dimensional crab farming device" with patent number ZL201110280120.8 (authorization announcement number CN102440213B), the invention patent "Blue crab single-body frame indoor cement pool farming device and farming method thereof" with patent number ZL201310069565.0 (authorization announcement number CN103155887B), and the invention patent application with application number CN201511013623.3 (application publication number CN105475209A), etc. Although land-based single-body crab farming can simulate the natural ecological conditions of pond farming to a certain extent, it still has defects such as insufficient water exchange, difficulty in sewage discharge, and difficulty in cleaning the farming container, which leads to slow growth of crabs.

[0004] Therefore, pond farming and land-based single-body farming each have their own advantages and disadvantages. In order to combine the two, the invention patent with patent number ZL201310634646.0 "An industrial automatic feeding system suitable for aquaculture" (authorization announcement number CN103858808B) discloses an automatic feeding system, which includes a track set above the breeding pond, a breeding basket group with a positioning identification plate set in the breeding pond, and a feeding device that can move along the track. By driving the feeding device to move to the feeding point where feeding is required, the breeding basket can be automatically and accurately fed. However, the patent has the following problems: 1. Although the patent only needs to use one feeding device, the feeding device needs to move back and forth to different feeding points for feeding when in use, and each breeding basket in the breeding pond is set statically relative to the breeding pond, which leads to insufficient water flow, thereby affecting the growth of crabs; 2. The feeding device has a complex structure, and the general feeding device on the market cannot be applied; 3. Intertidal crabs such as blue crabs need to be regularly exposed to dry, but the breeding system is designed for 24h immersion. Therefore, it is urgent to solve the problem of how to achieve fixed-point and single-point feeding and water flow, and to achieve regular drying of the breeding baskets. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a crab breeding device which can complete feeding by setting only one feeding point in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a crab farming device which can increase the crab farming amount and at the same time use the same feeding point, thereby making intensive farming more prominent.

[0007] The third technical problem to be solved by the present invention is to provide a crab breeding device which can realize accurate feeding and regular drying of blue crabs.

[0008] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a crab breeding device, characterized in that it comprises:

[0009] A breeding box group, the breeding box group includes a main body and at least two breeding boxes arranged at intervals along the circumference of the main body, each breeding box is provided with a feed inlet, and the feed inlets of each breeding box are arranged one by one in the circumferential direction;

[0010] A connecting mechanism, used to connect the breeding box group and suspend it on the breeding pond;

[0011] A first driving member, whose power output end is connected to the above-mentioned breeding box group, is used to drive the breeding box group to rotate, so that the feed inlet of each breeding box can rotate circumferentially with the rotation of the breeding box group;

[0012] as well as

[0013] The feeding device is arranged on the breeding pond and comprises a feeding part for feeding into each breeding box. When the breeding box rotates circumferentially, the feeding part can correspond one-to-one with the feeding port of any breeding box, thereby completing the feeding of each breeding box.

[0014] To further solve the second technical problem, preferably, there are at least two groups of breeding box groups, and the connecting mechanism includes a bracket for connecting to the breeding pond, a slide rail mounted on the bracket, and at least two slides movably arranged on the slide rail. Each breeding box group has a corresponding slide, and the center of the body of each breeding box group is rotatably connected to the respective slide through a rotating shaft; the breeding device also includes a second driving mechanism for driving each breeding box group to move to the position of the feeding device in sequence, and the first driving member and the second driving mechanism are both arranged on the slide; wherein:

[0015] The second driving mechanism includes a second driving member and a second transmission mechanism connected to the second driving member. The second transmission mechanism can convert the rotational power of the second driving member into the movement of the slide seat and the corresponding breeding box groups along the slide rail. When in use, each group of breeding box groups is moved to the feeding device, and then the breeding box groups are driven to rotate to complete the feeding. During the whole process, the crab breeding volume is increased while a feeding device is used, making the intensive breeding of crabs more prominent; and the moving breeding box group can further promote the flow of water; at the same time, the device of the present application is convenient for observing, harvesting and managing crabs in one location.

[0016] Each driving member needs power to work, and each driving member needs to move with the slide seat. In order to reduce weight and avoid interference from power lines, the slide rail further includes two openings that are arranged face to face and are U-shaped sub-slide rails. Each sub-slide rail includes an upper transverse portion and a lower transverse portion and a vertical portion connecting the upper transverse portion and the lower transverse portion. The upper transverse portion continues to extend upward to form a convex wall. The inner wall surface of the convex wall facing the opening has a conductive slide rail. Correspondingly, the slide seat includes an "I"-shaped slide seat body. The slide seat The main body includes an upper slide portion and a lower slide portion, wherein the upper slide portion has an upper pulley that can slide relative to the upper transverse portion, and correspondingly, the upper transverse portion has an upper slide rail for the upper pulley to slide, wherein a circuit control box is also provided on the upper slide portion of the slide, and the circuit control box is electrically connected to a conductive strip that is electrically connected to the conductive slide rail, and when the upper pulley of the upper slide portion moves relative to the upper slide rail, the conductive slide rail provides power to the second drive member and the first drive member via the conductive strip and the slide. In this way, the conductive slide rail can conduct electricity to the first and second drive members when it is energized. In order to improve the safety of use, an insulating sleeve can be provided on the slide rail and the slide seat, and / or a canopy can be provided above the slide rail.

[0017] Furthermore, the lower sliding seat portion has a lower pulley that can slide relative to the lower transverse portion; wherein,

[0018] The second driving member includes a second motor connected to the lower slide seat portion, and the second transmission mechanism includes a gear and a rack connected to the power output end of the second motor. The rack is arranged on the vertical portion of the sub-slide rail and meshes with the gear. When the upper pulley of the upper slide seat portion slides synchronously with the upper slide rail and the lower pulley of the lower slide seat portion slides synchronously with the lower transverse portion, the conductive slide rail provides power to the second driving member via the conductive bar and the upper slide seat portion and the lower slide seat portion of the slide.

[0019] In order to simultaneously install the first drive member and the second drive mechanism on the same slide without affecting the movement of the slide and the rotation of the breeding box group, further, a connecting seat for connecting the first drive member is connected to the lower slide portion, and the connecting seat is exposed outside the opening formed by the sub-slide rails arranged face to face, and the connecting seat has a receiving cavity for accommodating the first drive member, and the first drive member includes a first motor arranged at the bottom of the connecting seat, and the upper end of the rotating shaft passes through the bottom of the connecting seat, and the power output shaft of the first motor is connected to the upper end of the rotating shaft through a first transmission mechanism, and the first transmission mechanism includes a driving pulley driven to rotate by the first motor, a driven pulley coaxially arranged with the rotating shaft, and a transmission belt connecting the driving pulley and the driven pulley, and the conductive slide rail supplies power to the first motor through the conductive strip and the lower slide portion and the connecting seat. Of course, the output end of the above-mentioned first motor can also be directly connected to the rotating shaft without the need to set up a first transmission mechanism. Setting up the first transmission mechanism is conducive to controlling the rotation speed of the rotating shaft.

[0020] The second driving mechanism has two groups, and the racks in each group are respectively arranged on the inner wall surface of the vertical part of the two sub-slide rails, and the second motors and gears in each group are respectively located on both sides of the lower slide seat and are arranged corresponding to their respective racks. Furthermore, by controlling the rotation speed of each second motor, the slide seat can achieve linear or curved motion along the slide rail.

[0021] The shape of the slide rail can be designed as required, such as "I" shape, S shape, etc. Preferably, the slide rail is connected end to end to form a "U" shape. By moving the slide seat clockwise or counterclockwise, the breeding box groups on each slide seat can be moved to the feeding device in sequence, which is convenient for fixed-point feeding; and the rotating breeding box group can stir the water body to promote the fluidity of the water body. At the same time, stirring the water body can collect the dirt in the breeding pool to one place, which is convenient for cleaning the dirt.

[0022] Since crabs cannot grow without water, the breeding box group of the present application is mostly set in the water. When feeding, the rotation of the breeding box group will inevitably drive the water flow, so there is a problem that the water flow affects the accuracy of feeding. In order to further solve the above-mentioned third technical problem, preferably, the breeding box group can be set on the connecting mechanism so that it can move up and down; it also includes a third driving mechanism that is set on the connecting mechanism and is transmission-connected to the breeding box group to drive each breeding box group to move up and down relative to the breeding pool. Therefore, when feeding is needed, the breeding box group is moved upward so that the breeding box group leaves the water surface, and then the breeding box group is rotated to achieve accurate feeding. And the breeding box group that leaves the water surface can also be dried regularly to avoid the breeding box group from being immersed in water for a long time, and is thus suitable for intertidal crabs such as blue crabs. Of course, for crabs such as swimming crabs that need to be immersed in water for a long time, the accuracy of feeding in water can be improved by reducing the rotation of the breeding box group and then slowing down the flow of water.

[0023] Furthermore, the third driving mechanism includes a third motor and a screw-nut pair arranged on the connecting mechanism, the screw in the screw-nut pair is connected to the output shaft of the third motor, and the nut in the screw-nut pair is connected to the breeding box group. The nut and the breeding box group connected to the nut can be driven to move up and down by rotating the screw.

[0024] In the above scheme, the inside of the breeding box can be one or more layers. The cleanliness of the inside of the breeding box will affect the growth of crabs to a certain extent. Therefore, preferably, the breeding box is divided into at least two layers by a partition, the upper layer forms a breeding cavity for breeding crabs, and the lower layer forms a sewage collection cavity for collecting sewage. The partition is provided with a through hole for sewage to pass through. The feed port is provided at the upper part of the breeding box and is connected to the breeding cavity. The lower part of the breeding box is provided with a sewage outlet connected to the sewage collection cavity. The main body can throw out the sewage in the sewage collection cavity during the rotation and / or movement process, and no manual cleaning is required. The water body can also enter the breeding box from the sewage outlet to ensure the fluidity of the water body in the breeding box; at the same time, the sewage is separated from the crab by setting the partition, which is easy for the crab to grow.

[0025] Furthermore, the above-mentioned breeding pond is also included, wherein a water inlet is provided on one side of the breeding pond, a water outlet is provided on the other side, and the bottom surface of the breeding pond is inclined downward from the side where the water inlet is located to the side where the water outlet is located. In this way, the dirt in the breeding pond can be concentrated to the water outlet and discharged, so as to achieve self-purification of the water body. Of course, the breeding device of the present application can also be directly applied to crab breeding places such as ponds and rivers.

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] By providing a feeding device, and the breeding box group can be rotatably arranged on the connecting mechanism, the feeding ports of each breeding box in the breeding box group are distributed circumferentially, and the crabs in all the breeding boxes can be fed at the same feeding place by rotating the breeding box group; and this can be achieved by using the existing feeding device; at the same time, the device of the present application is convenient for the staff to observe the growth of crabs in each breeding box at one observation point, and is convenient for collecting and releasing crabs; the breeding box group can promote the flow of water during the rotation process, and the flowing water can better simulate the environment of crabs under natural conditions, thereby being beneficial to the growth of crabs, especially during the spawning period of blue crabs, a certain water flow stimulation is very beneficial to the spawning of blue crabs, and an appropriate water flow rate can take away harmful substances such as ammonia and nitrogen in the water.

[0037] The present invention is further described in detail below with reference to the accompanying drawings.

[0038] like Figures 1 to 5 As shown, a preferred embodiment 1 of a crab breeding device of the present invention is shown, and the crab breeding device includes a breeding pond 1, a feeding device 2, a bracket 3, a slide rail 4, a slide seat 5, a breeding box group, a first driving member 8 and a second driving mechanism 9.

[0039] Among them, a water inlet is provided on one side of the breeding pond 1, and a water outlet is provided on the other side, and the bottom surface of the breeding pond is inclined downward from the side where the water inlet is located to the side where the water outlet is located.

[0040] There is only one feeding device 2 and it is arranged on the side of the culture pond 1. The feeding device 2 is provided with a feeding part with a discharge port 20. The structure of the feeding device 2 can be designed with reference to the prior art. Of course, the feeding device can also be fed manually.

[0041] The bracket 3 is placed across the culture pond 1; the slide rail 4 is horizontally mounted on the bracket 3 and is located below the bracket 3, and the slide rail 4 is connected end to end to form a "U" shape; the slide seat 5, the culture box group, the first drive member 8 and the second drive mechanism 9 are 6 groups (of course, they can also be one or more groups, which are designed according to actual needs). In this embodiment, one group is taken as an example for description, as follows:

[0042] The breeding box group in this group includes a main body 77 and a plurality of breeding boxes 7 (the number of breeding boxes 7 can be designed according to needs), each breeding box 7 is connected by the main body 77, and is arranged on the outer edge of the main body 77 at intervals along the circumferential direction, and each breeding box 7 is provided with a feed port 70. In this embodiment, the feed port 70 of each breeding box 7 is distributed in a circle with the center of the main body 77 as the center, so as to be aligned one by one in the circumferential direction. The discharge port 20 of the above-mentioned feeding device 2 is located above the feed port 70 of any breeding box, and can be opposite to the feed port 70 on each breeding box 7 in turn when the main body 77 is rotated, and then, by rotating the main body 77, fixed-point and quantitative feeding can be achieved. In order to observe the situation of crabs in the breeding box 7, a high-speed camera can be set on the discharge port 20 of the feeding device 2, and the high-speed camera is facing the feed port 70. As Figure 5 As shown, each breeding box 7 in this embodiment is divided into two layers by a partition 71, and the upper layer forms a breeding chamber 72 for breeding crabs. In this embodiment, only one crab is raised in each breeding chamber 72, which solves the problem of crabs killing each other from the source, and ensures that there is sufficient dissolved oxygen in each breeding box 7. The lower layer forms a sewage collection chamber 73 for collecting sewage, and the partition 71 is provided with a through hole for sewage to pass through. The feed port 70 is provided on the upper end surface of the breeding box 7 and is connected to the breeding chamber 72, and the feed port 70 is tilted outward to facilitate feeding. The lower part of the breeding box 7 is provided with a sewage outlet 74 connected to the sewage collection chamber 73. By controlling the aperture of the through hole, it can be achieved that only sewage can pass through, while the input materials cannot pass through.

[0043] The slide 5 in the group is movably arranged on the slide rail 4, the body 77 is arranged horizontally, the center of the body 77 is rotatably arranged on the slide 5 through the rotating shaft 78, the output end of the first driving member 8 is transmission-connected with the rotating shaft 78 to drive the rotating shaft 78 to rotate, and the output end of the second driving mechanism 9 is transmission-connected with the slide 5 to drive the slide 5 to move along the slide rail 4. Specifically:

[0044] The slide rail 4 includes two openings that are arranged face to face and are U-shaped sub-slide rails 40. Each sub-slide rail 40 includes an upper transverse portion 401 and a lower transverse portion 402 and a vertical portion 403 connecting the upper transverse portion 401 and the lower transverse portion 402. The upper transverse portion 401 continues to extend upward to form a convex wall 404, and the inner wall surface of the convex wall 404 facing the opening has a conductive slide rail 41. The slide 5 includes an I-shaped slide body 53 and a connecting seat 54 arranged below the slide body 53. The slide body 53 includes an upper slide portion 531 and a lower slide portion 532. The upper slide portion 531 has an upper pulley 52 that can slide relative to the upper transverse portion 401. Correspondingly, the upper transverse portion 401 has an upper slide rail 405 for the upper pulley 52 to slide. A circuit control box 500 is also arranged on the upper slide portion 531 of the slide 5. The circuit control box 500 is electrically connected to a conductive bar 100 that is electrically connected to the conductive slide rail 41. When the upper pulley 52 of the upper slide portion 531 moves relative to the upper slide rail 405, the conductive slide rail 41 provides power to the second drive member and the first drive member 8 via the conductive bar 100 and the slide 5. The lower sliding seat 532 has a lower pulley 51 that can slide relative to the lower transverse portion 402; wherein the second driving mechanism 9 includes a second motor 91 connected to the lower transverse portion 402, the output shaft of the second motor 91 is connected to the slide rail 4 through a second transmission mechanism, and the second transmission mechanism can convert the rotational power of the second motor 91 into a structure that enables the slide 5 and the corresponding breeding box groups to move along the slide rail 4. The second transmission mechanism can be a structure that cooperates with a gear and a rack (such as a gear connected to the output shaft of the second motor, and a rack arranged on the slide rail along the length of the slide rail), or a structure that is connected to the rotating shaft of the lower pulley 51, so that the slide 5 can move along the slide rail 4 under the action of the second motor 91. Of course, it can also be other structures. In this embodiment, the second driving mechanism 9 has two groups and is respectively arranged corresponding to each sub-slide rail 40. When the slide 5 moves to the corner of the slide rail 4, the turning of the slide 5 can be achieved by controlling the rotation speed of the two second motors 91. The conductive slide rail 41 provides power to the second motor 91 via the conductive strip 100 and the upper slide seat portion 531 and the lower slide seat portion 532 of the slide seat 5 .

[0045] The above-mentioned connection seat 54 is used to connect the first driving member 8. The connection seat 54 is exposed outside the opening formed by the sub-slide rail 40 arranged face to face. The connection seat 54 has a accommodating cavity 50 for accommodating the first driving member 8. The first driving member 8 includes a first motor 81 arranged at the bottom of the connection seat, and the rotating shaft 78 is arranged vertically. The upper end of the rotating shaft 78 passes through the bottom of the connection seat 54. The power output shaft of the first motor 81 is connected to the upper end of the rotating shaft 78 through a first transmission mechanism. The first transmission mechanism includes a driving pulley 82 driven to rotate by the first motor 81, a driven pulley 83 coaxially arranged with the rotating shaft 78, and a transmission belt 84 connecting the driving pulley 82 and the driven pulley 83. The conductive slide rail 41 provides power to the first motor 81 through the conductive strip 100 and the lower slide seat portion 532 and the connection seat 54. Of course, the present application can also directly set components such as power supply, wires, etc. to be connected to the first and second motors to directly power the motors. The main body is in a circular ring shape, and its center is connected to the lower end of the rotating shaft 78. Then, the first motor 81 drives the rotating shaft to rotate through the first transmission mechanism, thereby driving the breeding box group to rotate.

[0046] In this embodiment, in order to reduce the impact of water on the aquaculture device, only the main body 77 and the aquaculture box group are located in the water of the aquaculture pond 1, and the bracket 3, the slide rail 4, the slide seat 5, the first drive member, and the second drive mechanism are all located above the water surface. For details, see Figure 1 The breeding box 7 is arranged at the upper layer of the water body, which can achieve a filtering effect. The dirt produced by the crabs will be deposited on the bottom surface of the breeding pond 1 after being discharged from the breeding box 7. The movement and rotation of the main body 77 drive the water body to flow, and the structural design of the bottom surface of the breeding pond 1 with one side high and the other side low can lead the dirt to the water outlet for discharge, thereby achieving the effect of self-purification of the water body of the breeding pond 1 itself.

[0047] In actual application, the second motor 91 is started to move a certain breeding box group to the feeding device 2, so that the feed port 70 on any breeding box 7 on the breeding box group is opposite to the discharge port 20 of the feeding device 2, and then the first motor 81 is started, and the rotation speed of the first motor 81 is controlled to make the breeding box group rotate at a certain speed. The feed port 70 on each breeding box 7 on the breeding box group can rotate circumferentially with the rotation of the breeding box group, and then align with the discharge port 20 of the feeding device 2 in turn, and complete the feeding. After all the breeding boxes 7 on the breeding box group have completed the feeding, the second motor 91 is started again to make the breeding box group leave the feeding device 2, and then drive another breeding box group to move to the feeding device 2, and feed according to the above steps.

[0048] Since the breeding box group is located in the water body, in order to avoid the failure of feeding due to the flow of water, which causes the material coming out of the discharge port 20 of the feeding device 2 to be unable to accurately enter the feed port 70 of the breeding box 7, the discharge port 20 of the feeding device 2 can be telescopically set. When feeding, the discharge port 20 is completely extended into the breeding box 7, and then retracted to its original position after feeding is completed; of course, the rotation speed of the main body 77 can also be reduced so that the water flow cannot affect the feeding; or other methods can be used.

[0049] Embodiment 2:

[0050] like Figures 6 to 9 As shown, it is a preferred embodiment 2 of a crab breeding device of the present invention, which is basically the same as the embodiment 1, except that each breeding box group in this embodiment can be arranged on a rotating shaft 78 so as to move up and down relative to the breeding pool. Specifically, it includes a third driving mechanism 6 arranged on the rotating shaft 78 and connected to the breeding box group to drive each breeding box group to move up and down, and the third driving mechanism 6 includes a third motor 61 and a screw nut pair arranged on the rotating shaft 78, the screw 62 in the screw nut pair is arranged vertically and connected to the output shaft of the third motor 61, and the nut 63 in the screw nut pair is connected to the breeding box group. Furthermore, the third motor 61 can drive the screw 62 to rotate, and the nut 63 sleeved on the screw 62 can move vertically along the screw 62, thereby driving the breeding box group to move vertically.

[0051] Meanwhile, in this embodiment, a shaft sleeve 130 is sleeved at the connection between the rotating shaft 78 , the third motor 61 and the screw rod 62 to protect the third motor 61 .

[0052] In order to improve the structural stability and enable the breeding box group to move up and down stably, it also includes a vertically arranged guide column 140. The bottom surface of the above-mentioned sleeve 130 is correspondingly provided with a guide hole 1300. The lower end of the guide column 140 is connected to the breeding box group, and the upper end passes through the guide hole 1300, so that the breeding box group can move up and down along the guide column 140.

[0053] And if Figure 8 As shown, in this embodiment, there are two groups of second drive mechanisms 9, each group of second drive mechanisms 9 includes a second motor 91 disposed on the slide seat portion 532 under the slide seat 5, the output shaft of the second motor 91 is connected to the slide rail through a second transmission mechanism, and the second transmission mechanism includes a gear 92 connected to the output shaft of the second motor 91 and a rack 93 disposed on the vertical portion 403 of the sub-slide rail 40 and matched with the gear 92. The racks 93 in each group are respectively disposed on the inner side surface of the vertical portion of each sub-slide rail 40, and the second motors 91 and gears 92 in each group are respectively disposed on the left and right sides between the upper slide seat portion 531 and the lower slide seat portion 532 corresponding to their respective racks 93.

[0054] The device of this embodiment is more suitable for the breeding of intertidal crabs such as blue crabs. When it is necessary to dry out, the breeding box group can be moved upward to be out of the water surface; after the drying out, the breeding box group can be moved downward to the water body. Of course, when feeding, in order to improve the accuracy of feeding, the discharge port of the feeding device is set above the water surface, and the breeding box group is driven to move upward to the water surface, so that the feeding port of the breeding box and the discharge port of the feeding device are opposite to each other, and feeding can be carried out to avoid the influence of water flow on feeding.
