DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-6 The present invention is further described:

[0020] Example 1

[0021] An automatic cage loading device for aquaculture, wherein a hopper 2 is provided on the top of a support 1, and the bottom of the hopper 2 is a cone for convenient discharge of materials, and six discharge ports are provided at the bottom of the cone, and a control valve 3 is provided at the discharge port. By changing the size of the opening of the control valve 3, the discharge amount of scallops per unit time is controlled. A conveyor belt 4 is provided below the discharge port, and a silo 5 is provided below the discharge end of the conveyor belt 4. Scallops fall from the discharge port of the hopper 2 onto the conveyor belt 4, and are then conveyed to the silo 5 by the conveyor belt 4. A discharge port is provided at the bottom of the silo 5, and a bottom plate 6 is provided at the discharge port to be opened and closed by a control mechanism, and an arc groove for placing and positioning a net cage 7 is provided below the discharge port, and the arc groove is contoured to the shape of the net cage 7. An arc groove for placing the net cage 7 is provided below the discharge port, and the net cage 7 is fixed by the arc groove, and is opened after being fixed to wait for receiving materials. The net cage is in the open state as shown in FIG. Figure 6As shown, an outer net is provided on the outer periphery of the frame of the net cage, and an inner net is installed on the frame. The outer net and two adjacent inner nets form a net cavity for holding scallops. The net cage is cylindrical as a whole, and the middle of the frame can be opened and closed and fixed. When the cage is filled, the net cage is opened to expose the internal net cavity, and the scallops are loaded into the net cavity.

[0022] The bottom plate 6 is slidably connected to the discharge port of the silo 5. The control mechanism includes a connecting plate 8 connected to the bottom plate 6. The connecting plate 8 is slidably connected to the guide rail 9 through a slider. A nut is fixed at the bottom of the connecting plate 8. A lead screw 10 passes through and is threadedly connected to the nut. The lead screw 10 is connected to a stepper motor 11. The stepper motor 11 is connected to a controller. The controller is connected to a weighing sensor 16 for monitoring the weight of the silo. The controller is connected to a driving motor of the conveyor belt 4. The guide rail 9 is fixed to the bottom of the mounting frame 12. The stepper motor 11 is fixed to the side of the mounting frame 12. The mounting frame 12 is fixed to the bottom of the bracket 1. The stepper motor 11 drives the lead screw 10 to rotate, so that the nut drives the connecting plate 8 to move axially along the lead screw 10, and the connecting plate 8 drives the bottom plate 6 to move along the guide rail 9, thereby realizing the opening and closing of the discharge port of the silo 5. When the cage is filled, the bottom plate 6 is opened, the conveyor belt 4 moves, and the scallops are conveyed to the silo 5. The weighing sensor monitors the weight change of the silo 5. When the weight reaches the preset value, a signal is sent to the controller. The controller sends an instruction, the conveyor belt 4 stops, the stepper motor 11 is started, the bottom plate 6 moves to open the feed opening, and the scallops enter the net cage 7 below from the silo 5. After the cage is filled, the feed opening is closed, the conveyor belt 4 is started, and the silo 5 continues to be loaded, entering the next working cycle.

When the pulling rope 14 is not pulled, the bottom plate 6 is blocked at the discharge port under the action of the spring hinge 13, the bidirectional rotating motor drives the rotating reel 15 to rotate, and the pulling rope 14 is received on the rotating reel 15, the pulling rope 14 pulls the bottom plate 6 to overcome the action of the spring hinge 13 and flip, and the discharge port is opened, when the discharge port needs to be closed, the bidirectional rotating motor reverses and rotates, driving the rotating reel 15 to release the pulling rope, and the bottom plate 6 is reset under the action of the spring hinge 13 to close the discharge port. When the cage is filled, the bottom plate 6 is opened, the conveyor belt 4 moves, and the scallops are conveyed to the silo 5. The weighing sensor monitors the weight change of the silo 5.
