when the floating frame floats downwards to enable the guide sleeve to abut against the lower limiting block, the sliding plunger moves downwards into the vertical blanking pipe to plug the vertical blanking pipe, so that bait in the bin stops falling, meanwhile, the lower piston moves downwards into the blanking valve sleeve and abuts against the inner limiting block under the action of a third balance weight, so that the lower piston seals the blanking valve sleeve, seawater is prevented from entering the connecting pipe and the bin through the blanking valve sleeve, and when the lower piston abuts against the inner limiting block, the upper piston moves downwards into the blanking cylinder body and is separated from the feeding valve sleeve, so that the bait in the connecting pipe falls into the blanking cylinder body;
so, at the continuous in-process that floats from top to bottom of floating frame, realize carrying out the bait of puting in of intermittent type formula to the aquaculture net case, and the partly bait in the feed bin of puting in at every turn, so, what make bait can be timely is eaten by the fish in the aquaculture net case, avoid bait to sink and pass the aquaculture net case, thereby effectively solve present deep sea aquaculture net case's artifical feed mode, it does not eat by the fish in the aquaculture net case to have a large amount of bait, just sink and pass the aquaculture net case, cause the serious waste of bait and a large amount of incomplete bait deposit to the seabed, influence the problem of ocean bottom material environment.
Further, as shown in fig. 2, the upper end of the bin 6.2 is open, the upper end of the bin is provided with an upper cover 6.9, the upper cover comprises a cover plate for covering the upper end opening of the bin and a sleeve body formed by extending the edge of the cover plate downwards, and the sleeve body is sleeved on the bin. The upper cover is fixed on the vertical connecting rod. So, can be under the condition that does not influence intermittent type feed mechanism work, cover the upper end opening that covers the feed bin through the upper cover.
Further, as shown in fig. 2, the floating frame 6.1 comprises a floating block 6.1.1 floating on the sea surface, a floating rod 6.1.2 positioned above the supporting floating frame and a connecting rod 6.1.3 connecting the floating rod and the floating block. The guide sleeve is arranged on the floating rod. The upper end of the vertical connecting rod is connected with the floating rod, and the lower end of the vertical connecting rod is connected with the sliding plunger.
Furthermore, the feeding valve sleeve is coaxial with the discharging valve sleeve.
Further, as shown in fig. 3, the lower end of the discharging valve sleeve is also provided with a protective mesh enclosure 6.17, the protective mesh enclosure is positioned in the aquaculture net cage, and the lower end of the discharging valve sleeve is positioned in the protective mesh enclosure. Therefore, the normal work of the intermittent feeding mechanism is influenced when the fishes in the aquaculture net cage enter the baiting valve sleeve.
Further, as shown in fig. 2, the lower end of the storage bin is a conical blanking part 6.21 with the inner diameter gradually decreasing from top to bottom.
Further, as shown in fig. 3, the lower end of the blanking cylinder is a conical material guiding portion 6.41 with an inner diameter gradually decreasing from top to bottom.
