As shown in figure 1, the device for discharging the dead shrimp shells of the aquatic shrimps is arranged at the position of a sewage discharge pipe at the bottom of a culture pond 1, the bottom surface of the culture pond 1 close to a sewage discharge pipe opening 2 is a conical surface, and the dead shrimp shells can be conveniently gathered towards the position of the sewage discharge pipe opening 2.

The blowdown mouth of pipe 2 is connected with blow off pipe 3, just be equipped with blowoff valve 4 on the blow off pipe 3, blowoff valve 4 still electric connection has the controller, and operating personnel accessible controller control blowoff valve 4 opens and close.

The dead shrimp shell discharger comprises an escape-proof cap 5, a connecting rod 6, a retainer 7, a bottom cover plate 8 and a movable rod 9, wherein the escape-proof cap 5 is arranged above the sewage discharge pipe orifice 2 and can cover the sewage discharge pipe orifice 2, and the maximum outer diameter of the escape-proof cap 5 is larger than the caliber of the sewage discharge pipe orifice 2. The retainer 7 comprises a cylindrical part 71 and a sliding sleeve 72, the cylindrical part 71 is fixedly arranged on the inner wall of the sewage pipe opening 2, the sliding sleeve 72 is vertically arranged above the cylindrical part 71 and coaxial with the cylindrical part 71, and the outer wall surface of the sliding sleeve 72 is fixedly connected with the cylindrical part 71 through a plurality of connecting rods 73.

The bottom surface and the bottom cover plate 8 of cylinder 71 are articulated with one side, connecting rod 6 wears through sliding sleeve 72 and with sliding sleeve 72 clearance fit, connecting rod 6 and holder 7 sliding connection promptly, the upper end of connecting rod 6 with prevent escaping cap 5 and be connected, the lower extreme of connecting rod 6 is articulated with the first end of movable rod 9, the second end and the 8 top surfaces of bottom cover plate of movable rod 9 are articulated, when blowoff valve 4 is closed, connecting rod 6 orders about 8 shutoff blow off pipe mouths 2 of bottom cover plate under the buoyancy of cap 5 of preventing escaping in order to form a dirt collecting groove, and when opening blowoff valve 4, prevent escaping cap 5 whereabouts and make bottom cover plate 8 open the dirt collecting groove, and the live shrimp that gathers in the dirt collecting groove receives the water disturbance and free, dead shrimp shell is discharged through the blow off pipe.

Wherein, prevent escaping cap 5, connecting rod 6 and holder 7 coaxial line, prevent escaping cap 5 and be the toper, and the outer top surface fixedly connected with adjusting nut 11 of toper, 6 upper ends of connecting rod are worn through and are prevented escaping cap 5 and with adjusting nut 11 spiro union, and the part rigid coupling that connecting rod 6 stretches out to outside adjusting nut 11 has backstop piece 10, backstop piece 10 can avoid 6 upper ends of connecting rod to break away from and prevent escaping cap 5. Through adjusting 6 upper ends of the connecting rods and the relative position of the escape-proof cap 5 can make the blow-off valve 4 prevent escaping 5 bottom surfaces of the cap and leave a gap with the blow-off pipe orifice 2 when opening, so that the spiral water flow formed at the blow-off pipe orifice 2 during drainage can assemble more dead shrimps and shrimp shells in the dirt collecting groove on the one hand, and on the other hand can drive the dead shrimps and the shrimp shells to be discharged outwards fast, thereby being beneficial to saving water and avoiding the escape of the live shrimps.

Working process

When the sewage discharge device 4 is closed, the escape-proof cap 5 floats upwards, the connecting rod 6 drives the bottom cover plate 8 to seal the sewage discharge pipe orifice 2 under the buoyancy action of the escape-proof cap 5 to form a sewage collection groove, dead shrimp shells in the culture pond can be collected in the sewage collection groove, and live shrimps cannot escape at the moment because the bottom cover plate 8 seals the sewage discharge pipe orifice 2;

when the blowoff valve 4 is opened, the live shrimps are disturbed by water flow and quickly dissociate out of the sewage collection tank, meanwhile, the escape-proof cap 5 falls down under the action of the water flow, the bottom cover plate 8 opens the sewage collection tank, and the dead shrimps and the shrimp shells are discharged through the blowoff pipe 3, so that the dead shrimps and the shrimp shells can be cleaned in time to avoid polluting water; in addition, by adjusting the relative position of the connecting rod 6 and the escape-proof cap 5, if the distance between the top end of the connecting rod 6 and the top surface of the escape-proof cap 5 is reduced, a gap is reserved between the bottom surface of the escape-proof cap 5 and the sewage pipe orifice 2 when the sewage valve 4 is opened, so that the spiral water flow formed at the sewage pipe orifice 2 can gather more dead shrimps and shrimp shells in the sewage collecting groove on one hand, and can drive the dead shrimps and the shrimp shells to be quickly discharged outwards on the other hand, thereby being beneficial to saving water and avoiding live shrimps from escaping; and before blowdown, the blowdown valve 4 is opened and closed quickly, the produced water flow can more effectively drive away live shrimps, the live shrimps are prevented from escaping, and then the blowdown valve 4 is normally opened to finish the operation of discharging the dead shrimps and the shrimp shells.

The present invention has been described above by way of example, but the present invention is not limited to the above-described specific embodiments, and any modification or variation made based on the present invention is within the scope of the present invention as claimed.
