[0002] Land-based recirculating water fish farming is based on land and adopts a "controlled shore-based recirculating water aquaculture system". Its farming advantages are that the adult fish under this controlled system are pollution-free, have no earthy smell, have a good taste, and have considerable sales; it can achieve high-density farming, and the unit farming density can reach 40 times that of the traditional earth pond farming model. This controlled and efficient recirculating water farming has a wide range of scientific and technological applications. At the same time, through secondary sedimentation and artificial wetland treatment of aquaculture tail water, the aquaculture tail water can be recycled or discharged in compliance with standards, which is an environmentally friendly and efficient farming method.

[0003] Moreover, fish feces are a kind of organic fertilizer, which is rich in nitrogen, phosphorus, potassium and other nutrients.

[0028] See also Figure 1-7 The utility model provides a technical solution: a circulating aquaculture fish manure cleaning and collecting device, comprising a collecting frame 1, on which a transmission member for transmitting a fish manure body is rotatably connected, and a servo motor 3 for driving the transmission member to rotate is installed on the collecting frame 1; a gathering mechanism is mirror-imaged on both sides of the bottom of the collecting frame 1, and the gathering mechanism comprises a rotating cylinder 11, on which a plurality of gathering members 12 are installed, and the gathering member 12 comprises a gathering frame 12.1 fixedly connected to the rotating cylinder 11; a digging member is also arranged on the bottom of the collecting frame 1, and the digging member is arranged between the gathering member 12 and the transmission member, and the servo motor 3 drives the transmission member to rotate, and at the same time drives the gathering member 12 and the digging member to rotate through the transmission mechanism.

[0029] Specifically, the circulating water aquaculture fish feces cleaning and collecting device includes a collecting rack 1, and a transmission member for transmitting the fish feces body is rotatably connected to the collecting rack 1. Specifically, the transmission member is in an inclined state, and the bottom of the transmission member extends into the inside of the aquaculture pond to dig out the fish feces from the inside of the aquaculture pond. At the same time, a material receiving mechanism is also arranged on the top of the collecting rack 1. As the transmission member rotates, the fish feces on the transmission member are transmitted to the material receiving mechanism for material receiving operation, which greatly improves the practicality of the entire collecting device. The material receiving mechanism is a prior art, and its structure and working principle are not repeated here. A servo motor 3 for driving the transmission member to rotate is installed on the collecting rack 1 to meet the work needs. A gathering mechanism is arranged on both sides of the bottom of the collecting rack 1 in a mirror image. The two gathering mechanisms rotate to gather the fish feces at the bottom of the aquaculture pond, and then the fish feces are dug out through the transmission member to meet the work needs. The gathering mechanism includes a rotating cylinder 11, and a plurality of gathering members 12 are installed on the rotating cylinder 11. The gathering member 12 includes a gathering frame 12.1 fixedly connected to the rotating cylinder 11. Therefore, when the rotating drum 11 rotates, it will drive the gathering frame 12.1, and the fish feces at the bottom of the culture pond will be gathered during the rotation of the gathering frame 12.1. A digging piece is also provided at the bottom of the collecting frame 1, and the digging piece is provided between the gathering piece 12 and the transmission piece. The digging piece rotates to dig out the fish feces at the bottom of the culture pond.

The servo motor 3 drives the transmission piece to rotate, and at the same time drives the gathering piece 12 and the digging piece to rotate through the transmission mechanism. Therefore, during use, the servo motor 3 is started, and the servo motor 3 drives the transmission to rotate, and the transmission mechanism drives the gathering mechanism and the digging piece to rotate. Specifically, the servo motor 3 drives the rotating cylinder 11 to rotate through the transmission mechanism, and at the same time drives the gathering frame 12.1 to rotate, so that the fish feces at the bottom of the breeding pond can be gathered. During this stroke, the digging piece rotates to dig out the gathered fish feces. As the digging piece continues to rotate, the excavated fish feces will be flipped onto the transmission piece.

Therefore, during the working process, the servo motor 3 is started, and the servo motor 3 drives a rotating rod 5 to rotate through the coupling. When the rotating rod 5 rotates, it will drive another rotating rod 5 to rotate through the first synchronous member 6, and drive the two transmission rollers 4 and the transmission belt 2 to rotate to perform the fish manure transmission operation; when the rotating rod 5 rotates, it will drive the driving rod 7 to rotate through the second synchronous member 9, and during the rotation of the driving rod 7, it will drive multiple groups of digging plates 8 to rotate to perform the digging operation; when the driving rod 7 rotates, it will drive the second transmission rod 14 to rotate through the third synchronous member 16, and during the rotation of the second transmission rod 14, the transmission gear set 15 drives the first transmission rod 13 to rotate, and then can drive the rotating drum 11 to rotate. Therefore, when the rotating drum 11 rotates, it will drive the gathering frame 12.1.
