Technical Field

[0001] The utility model relates to the technical field of shrimp and crab breeding, in particular to a shrimp and crab breeding nest with a multi-layer structure. Background Art

[0002] Animals such as crabs have a very close relationship with humans. Some of them are the main targets of aquaculture or fishing, especially shrimps, lobsters and crabs. Humans use various tools to assist in the breeding of shrimps and crabs.

[0003] Shrimp and crabs have a certain sense of territory. In the process of artificial breeding, in order to better ensure the survival rate of shrimp and crabs, shrimp and crabs are cultured in special shrimp and crab nests. Existing shrimp and crab nests are generally made of artificial materials and equipped with opening and closing doors for feeding food or observing the growth of shrimp and crabs. However, the opening and closing doors of shrimp and crab nests generally need to be opened and closed manually. More shrimp and crab nests will take up more time of users. Utility Model Content

[0004] The purpose of the utility model is to provide a shrimp and crab breeding nest with a multi-layer structure to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-layer structure of shrimp and crab breeding nest, including columns, there are two columns, a plurality of diamond-shaped support rods are installed between the two columns, the plurality of diamond-shaped support rods are arranged longitudinally with each other, a plurality of transversely arranged hexagonal cages are installed on the left and right end surfaces of the diamond-shaped support rods, the surfaces of the hexagonal cages are rotatably connected with opening and closing doors, the front ends of the opening and closing doors are provided with through holes, the interiors of the two columns are rotatably connected with winding shafts, a plurality of traction ropes are installed on one of the winding shafts, the traction ropes pass through the plurality of through holes and are connected to the surface of the other winding shaft, a plurality of traction blocks with a size larger than the through holes are installed on the surface array of the traction ropes, and the spacing of the traction blocks is adapted to the spacing between the opening and closing doors.

[0006] Preferably, the four surfaces of the diamond-shaped support rod are provided with a plurality of slots in an array, and the two surfaces of the hexagonal cage away from the closing door are installed with blocks adapted to the slots.

[0007] Preferably, a plurality of the hexagonal cages on the same horizontal line form a group, and the plurality of groups of hexagonal cages are arranged longitudinally and contact each other.

[0008] Preferably, a support plate is installed at the bottom between the two uprights, and the upper end of the support plate contacts the lower end of a group of hexagonal cages.

[0009] Preferably, a driving device is installed at the lower end of the winding shaft, and the driving device is fixedly installed inside the column, and the two driving devices rotate synchronously.

[0010] Preferably, a through hole is provided at the center of the inner wall surfaces in contact with each other in the same group of hexagonal cages.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The shrimp and crab breeding nest of the multi-layer structure supports the diamond support rods by two columns. The diamond support rods are contacted in sequence and arranged longitudinally. The diamond support rods support multiple hexagonal cages. The multiple hexagonal cages are used to breed shrimps and crabs. When food needs to be fed into the hexagonal cages or the growth state of the shrimps and crabs needs to be penetrated, the two reel shafts are opened to rotate synchronously in the same direction. At this time, the traction rope drives the traction block to reel and move toward the surface of one reel shaft. The size of the traction block is larger than the through hole, which drives the opening and closing door to rotate. When the opening and closing door rotates to the maximum rotation angle, the rotation of the reel shaft is stopped. At this time, all the opening and closing doors are in the open state. Similarly, changing the rotation direction of the two reel shafts will cause the traction block to drive the opening and closing door to close. The traction rope and the traction block are driven to move by the two reel shafts, and the traction block drives the multiple opening and closing doors to rotate. The door of the hexagonal cage can be opened without manual operation, which saves the user's operation time to a certain extent.

[0013] 2. The multi-layer structure of the shrimp and crab breeding nest is provided with an opening and closing door that can be opened and closed synchronously. When the user needs to carry out mixed breeding of shrimps and crabs, since the shrimp and crab seedlings have the habit of preying on each other, the shrimp and crab seedlings can be classified and placed in layers inside the hexagonal cage, and the hexagonal cage is placed inside the lake. The living range of the seedlings can be restricted by the opening and closing door. After the seedlings have passed the development period, the opening and closing door can be opened, and the shrimps and crabs will enter the lake for autonomous reproduction, which effectively reduces the loss of shrimp and crab seedlings in their infancy.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] like Figures 1 to 5As shown, the shrimp and crab breeding nest with a multi-layer structure in this embodiment includes a column 1, and there are two columns 1. A plurality of diamond-shaped support rods 5 are installed between the two columns 1. The plurality of diamond-shaped support rods 5 are arranged longitudinally with each other, and the plurality of diamond-shaped support rods 5 are arranged along the vertical direction. Two adjacent diamond-shaped support rods 5 are in contact with each other. A plurality of transversely arranged hexagonal cages 2 are installed on the left and right end surfaces of the diamond-shaped support rods 5. The plurality of hexagonal cages 2 are sequentially installed on the left and right sides of the diamond-shaped support rods 5. An opening and closing door 3 is rotatably connected to the surface of the hexagonal cage 2. The installation positions of all the opening and closing doors 3 are all on one side of the hexagonal cage 2. A through hole 8 is opened at the front end of the opening and closing door 3. There is no fixed requirement for the shape of the through hole 8, and it can be adjusted according to the use The demand of the user is changed. The interior of the two columns 1 is rotatably connected with a winding shaft 11. A winding shaft 11 is installed with multiple traction ropes 4. The traction rope 4 has a certain length. When the two winding shafts 11 rotate synchronously in the same direction, the traction rope 4 will move in one direction. The traction rope 4 passes through multiple through holes 8 and is connected to the surface of the other winding shaft 11. The surface array of the traction rope 4 is installed with multiple traction blocks 9 whose sizes are larger than the through holes 8. When the traction rope 4 moves, it will drive the traction blocks 9 to move synchronously. The spacing of the traction blocks 9 is adapted to the spacing between the opening and closing doors 3. The multiple traction blocks 9 cooperate with the multiple opening and closing doors 3. When the traction blocks 9 contact the opening and closing doors 3, they will drive the opening and closing doors 3 to rotate.

[0023] Specifically, the four faces of the rhombus support rod 5 are provided with a plurality of slots 6 in an array, and the two faces of the hexagonal cage 2 away from the closing door 3 are provided with blocks 7 adapted to the slots 6. Figure 2 and Figure 3 As shown, by the cooperation between the clamping block 7 and the clamping slot 6 , the hexagonal cage 2 can be clamped on the surface of the diamond support rod 5 .

[0024] Furthermore, multiple hexagonal cages 2 on the same horizontal line are grouped together, and the multiple groups of hexagonal cages 2 are arranged vertically and contact each other. By arranging and installing the multiple groups of hexagonal cages 2 vertically, a multi-layer distribution can be formed, which is convenient for users to place more shrimps and crabs in a limited space.

[0025] Furthermore, a support plate 12 is installed at the bottom between the two columns 1, and the upper end of the support plate 12 contacts the lower end of a group of hexagonal cages 2. It should be noted that the diamond support rod 5 at the lower end does not contact the support plate 12, and there is a certain distance between them, and the size of the distance is half of the height of the hexagonal cage 2. When the bottom group of hexagonal cages 2 is clamped with the bottom diamond support rod 5, the lower end of the bottom group of hexagonal cages 2 will contact the upper end of the support plate 12, and the support plate 12 can support the hexagonal cages 2.

[0026] Furthermore, a driving device 10 is installed at the lower end of the winding shaft 11, and the driving device 10 is fixedly installed inside the column 1. The two driving devices 10 rotate synchronously. The driving device 10 is a common forward and reverse servo motor, which is installed inside the column 1 by bolts. The output end of the driving device 10 is connected to the lower end of the winding shaft 11, thereby driving the winding shaft 11 to rotate. The two driving devices 10 are connected to an external power supply and rotate synchronously in the same direction. It should be noted that the driving device 10 is controlled by an external control switch and can rotate in two different directions, corresponding to the rotation directions of opening and closing the opening and closing door 3 and closing the opening and closing door 3 respectively.

[0027] Furthermore, a through hole 13 is provided at the center of the inner wall surface where the hexagonal cages 2 in the same group are in contact, and the multiple hexagonal cages 2 in the same group are connected through the through hole 13 to facilitate the exchange of food or water resources.

[0028] The method of using this embodiment is as follows: two uprights 1 are used to support the diamond support rods 5, which are in contact with each other and arranged longitudinally in sequence, and a plurality of hexagonal cages 2 are supported by the diamond support rods 5. The plurality of hexagonal cages 2 are used to culture shrimps and crabs. When it is necessary to feed food into the hexagonal cages 2 or to penetrate the growth state of the shrimps and crabs inside, the two reel shafts 11 are opened to rotate synchronously in the same direction. At this time, the traction rope 4 will drive the traction block 9 to reel toward the surface of a reel shaft 11. The size of the traction block 9 is larger than the through hole 8, and it will drive the opening and closing door 3 to rotate. When the opening and closing door 3 rotates to the maximum rotation angle, the rotation of the reel shaft 11 is stopped. At this time, all the opening and closing doors 3 are in the open state. Similarly, changing the rotation direction of the two reel shafts 11 will make the traction block 9 The opening and closing doors 3 are driven to close, and the traction rope 4 and the traction block 9 are driven to move through the two winding shafts 11. The traction block 9 drives multiple opening and closing doors 3 to rotate, and the door of the hexagonal cage 2 can be opened without manual operation, which saves the user's operation time to a certain extent. It should be noted that by setting the opening and closing doors 3 that can be opened and closed synchronously, when the user needs to carry out mixed breeding of shrimps and crabs in the lake, due to the mutual predation habits of shrimp and crab seedlings, the shrimp and crab seedlings can be classified and layered and placed in the hexagonal cage 2, and the hexagonal cage 2 can be placed in the lake water. The living range of the seedlings can be limited by the opening and closing doors 3. After the seedlings have passed the development period, the opening and closing doors 3 can be opened, and the shrimps and crabs will enter the lake for autonomous reproduction, effectively reducing the loss of shrimp and crab seedlings in their infancy.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
