Detailed Description
In order to make the technical means, creation features, achievement objects and effects of the utility model easy to understand, the following embodiments are provided to specifically describe the mechanical device for catching and grading live fish in combination with the accompanying drawings.
The mechanized device for catching and grading the live fish is used for the processes of fish collection, fish suction, fish water separation and conveying grading, and realizes automatic harvesting of the live fish. As shown in fig. 1, the mechanized apparatus for catching and grading live fish comprises: the automatic walking fish collecting device comprises an automatic walking fish collecting device 1, a fish sucking pump 2, a fish-water separating device 3 and an automatic sorting device 4.
The automatic walking fish collecting device 1 is arranged in the fish pond 5 and is used for collecting fish in the fish pond 5. In the present embodiment, the self-propelled fish gathering device 1 includes a motor, a driving unit, a slide rail, and a grating plate. The motor is arranged on the shore of the fishpond 5, the driving unit is in driving connection with the motor, and the driving unit can be partially positioned outside the fishpond 5 and partially positioned inside the fishpond 5. In particular, the drive unit comprises a chain. The slide rails are arranged in the fishpond 5, can be arranged at the bottom of the fishpond 5, and can also be arranged at two sides of the fishpond 5. The bottom edges of the grid plates are in contact with the bottom edge of the fish pond, the width of the grid plates is the same as that of the fish pond, the grid plates are slidably mounted on the slide rails and connected with the driving unit, and the driving unit drives the grid plates to slide on the slide rails.
In this embodiment, the fish pond is rectangular.
The fish pump 2 is used for sucking fish in the fishpond, and a fish sucking pipeline 21 of the fish pump 2 extends into the fishpond 5. Specifically, the fish suction pump 2 sucks the fish in the fishpond from the fish suction duct 21 into the pump body by using the principle of vacuum negative pressure, and then discharges the fish from the fish discharge duct 22 by releasing the pressure. In this embodiment, the fish pump is a two-tank vacuum fish pump, which can be operated continuously.
The fish water separation device 3 is used for separating fish water from the fish pumped by the fish pump 2. The fish-water separating device 3 is connected with a fish outlet pipe 22 of the fish pump 2. The fish pump 2 pumps the fish up from the fish outlet pipe 22 into the fish water separating device 3. In this embodiment, the bottom of the fish-water separating device 3 is a grating, and water is filtered by the grating.
The automatic sorting device 4 is used for classifying the fish according to weight and outputting the classified fish. Each fish of weight class that automatic sorting device 4 sorted out all sets up a fish outlet 41, and the fish after the grading is exported from corresponding fish outlet 41. The automatic sorting device 4 is connected with the fish-water separating device 3. Specifically, an outlet is provided on a side wall of one end of the fish-water separating device 3 connected to the automatic sorting device 4 (i.e., a right side wall of the fish-water separating device 3 shown in fig. 1), and fish enters the automatic sorting device 4 from the outlet of the right side wall of the fish-water separating device 3.
