7. The continuous automatic injection device of the fishing vaccine according to claim 6, characterized in that the injection device (3) is fixed on a movable bracket (3-11), the movable bracket (3-11) can swing around the pivot of the plane of the L-shaped movable bracket (3-14), the rear part is provided with a cam groove (3-12), a cam is arranged in the cam groove (3-12), the supporting seat of the cam is fixed with the frame, the cam is driven by the driving device of the sliding table (3-10) together to drive the injection cylinder (3-4) to move in the X direction and the Y direction simultaneously to adapt to the position of the fish body, and the contour line of the cam groove (3-12) is set according to the horizontal and vertical distance coordinates of the injection points of different specifications of the fish body.
8. The automatic continuous fish vaccine injection apparatus according to claim 7, wherein: the sliding tables (3-10) are driven by screw rod motors in the sliding tables to drive movable supports fixed on the sliding tables to translate; the cylinder fixed on the inclined plane at the upper part of the movable bracket (3-11) drives the syringe to integrally reciprocate linearly at an angle of 45 degrees, and the moving distance is 10-30 mm; the piston in the injector presses the injected liquid medicine into the fish body through the injection needle, the movement of the piston in the injector is driven by another cylinder, and a piston push rod is provided with a spring to reset the piston after injection; the top of the piston push rod is provided with a thread which is connected with the nut, and the stroke of the piston is adjusted and pushed by adjusting the height position of the nut, so that the injection dosage is adjusted.
9. The automatic continuous fish vaccine injection apparatus according to claim 1, wherein: and the injection stations and the rotary pushing devices (4) are alternately arranged, and when the vision device detects that the fish belly faces backwards, the rotary pushing devices (4) of the corresponding stations and the injection stations are controlled to be triggered to act, so that injection is completed.
10. The automatic continuous fish vaccine injection apparatus according to claim 1, wherein: the rotary pushing device (4) rotates in a single direction.
