Description

Fish-plant symbiotic breeding device TECHNICAL FIELD

[0001] The utility model relates to fish-plant symbiotic breeding device technical field, specifically to a fish-plant symbiotic breeding device. BACKGROUND

[0002] The fish-plant symbiotic breeding device is an equipment integrating planting function and fish breeding function, which can meet the leisure and entertainment needs of people in planting flowers and grass and fish breeding.

[0003] For example, the applicant previously proposed a modified fish-plant symbiotic ecosystem disclosed in Chinese patent No. 202223138275.0, which comprises a filter module, a planting module, and a water circulation module. The planting module is fixed on the top of the filter module, and the water circulation module is connected to the filter module and the planting module through a hose. The planting module includes a planting tank and a planting cup. The planting module is installed with at least one layer of planting tank. The top of the planting module is provided with a shunt groove for distributing water source. The shunt groove delivers water source into the shunt groove through the water circulation module. The shunt groove is provided with a shunt port for water flow to the planting cup. The shunt port is provided with a drainage groove to facilitate water outflow. When the water level in the shunt groove reaches the height of the shunt port, the water starts to flow to each row of planting tanks respectively. This way will not cause uneven distribution and affect plant growth due to insufficient water source.

[0004] However, although this technical solution can use the shunt groove for shunting to avoid uneven distribution and affect plant growth due to insufficient water source, it still has some deficiencies in use. For example, the bottom surface of the splicing plug at the bottom of the shunt groove is a flat surface. When the water flows onto the bottom surface of the shunt groove, the water is easily dispersed to the four corners of the bottom surface of the shunt groove, making it difficult for the water to quickly and effectively drip into the planting cup, which affects the efficiency of plant root system absorbing water in the planting cup and affects the growth of plants to some extent.
