Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

A novel paddy field shrimp gradient culture device is shown in figures 1 and 2 and comprises a sewage disposal pond 1 and three pond bodies 2 which are respectively used for culturing a young shrimp stage, a middle shrimp stage and a shrimp forming stage of prawns, namely a first pond body 3, a second pond body 4 and a shrimp forming pond body 5, wherein the first pond body 3, the second pond body 4 and the third pond body 5 are respectively arranged from high to low in a staggered way through a fall, and the fall between the young shrimp pond body 3, the second pond body 4 and the third pond body 5 is 0.5-1 m; the water surface and the bottom of the first tank body 3, the second tank body 4 and the third tank body 5 are all arranged in a high-low falling and falling mode, the volumes of the first tank body 3, the second tank body 4 and the adult shrimp culture tank 5 are sequentially increased in proportion, and the bottoms of the first tank body 3, the second tank body 4 and the third tank body 5 are all conical bottoms; the position of the sewage disposal pool 1 is lower than that of the first pool body 3, the second pool body 4 and the third pool body 5, and the sewage disposal pool 1 is internally provided with a sewage disposal pipe 6 which leads to the bottoms of the juvenile shrimp pool bodies 3, the second pool body 4 and the third pool body 5 respectively; the first tank body 3 is provided with a pond moving pipe 7 leading to the second tank body 4, and the second tank body 4 is provided with a pond moving pipe 7 leading to the third tank body 5; a sewage discharge valve 12 is arranged on the sewage discharge pipe 6, and a pond moving valve 13 is arranged on the pond moving pipe 7; an inlet of the pond moving pipe 7 is arranged at the lower part of the conical bottom of the pond body 2, and an outlet of the pond moving pipe 7 is arranged at the upper part of the conical bottom of the pond body 2; specifically, two second tank bodies 4 are arranged in parallel, and a first tank body 3 and a sewage disposal tank 1 are arranged on the left side and the right side of each of the two second tank bodies 4; the front and the back of the first tank body 3, the second tank body 4 and the sewage disposal tank 1 are all provided with a third tank body 5. In addition, after further improvement, the pond moving pipe 7 is provided with a secondary inlet 14, and the secondary inlet 14 is positioned at the upper part of the conical bottom of the pond body 2.

As shown in fig. 3, an annular wall 8 is arranged in the middle or upper part of the conical bottom of the first tank body 3, the second tank body 4 or the third tank body 5, the top of the annular wall 8 is located below the liquid level, the annular wall 8 surrounds to form an annular tank 9, an opening and closing door 10 is arranged on the annular wall 8, and the inlet of the tank moving pipe 7 is located in the annular tank 9. The bottom of each tank body 2 is provided with a guide channel 11 leading to the center along the periphery of the conical bottom.

According to the three-dimensional three-stage prawn culture pond structure, prawns in different growth stages are respectively placed in different ponds, for example, when young prawns grow, the length of the prawns is less than 5cm, the prawns are placed in the first pond body 3, the prawns grow to be more than 5cm, the prawns are moved to the second pond body 4 through the pond moving pipe 7 to be cultured to be 7-9cm, and then the prawns grow again and are transferred to the third pond body 5 through the pond moving pipe 7 until the prawns are sold.

The annular wall 8 can be isolated with around with the annular pond 9 that it formed to set up on the annular wall 8 and open and close door 10, can carry out UNICOM and isolated with the annular wall 8 through opening and closing door 10 like this, thereby the discharge of the filth of being convenient for, the change of the interior water body of pond of being convenient for. For further improvement, the opening and closing door 10 is a double-layer door, one layer of the door is of a net structure and is arranged in a certain mesh hole, so that after all shrimp groups are driven into the annular pool 9, the small shrimp individuals can conveniently escape from the annular pool 9, and the rest shrimps are large and can be conveniently transferred into the next pool body or sold.

The guide ditch 11 is set to be a structure with a wider upper part and a narrower lower part, so that a living environment is formed for shrimps, and dirt can be promoted to fall down and is concentrated to the center of the pool body.

The structure is divided into three ponds with different areas for respectively culturing shrimps in different stages, so that the pond can be recycled, and the culture efficiency is greatly improved; the three ponds have certain height difference, which is beneficial to automatically changing the ponds and discharging sewage by utilizing water flow; the area of each pond can be relatively accurately calculated through the size, the culture density and the growth time of the shrimps, and the effect of efficiently utilizing the ponds is achieved.

The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention, but all the insubstantial modifications or changes made within the spirit and scope of the main design of the present invention, which still solve the technical problems consistent with the present invention, should be included in the scope of the present invention.
