technical field

The utility model belongs to the technical field of mariculture, and in particular relates to a buoy type bait throwing machine.

Background technique

As natural fish stocks decline due to environmental change and overfishing, vigorous development of marine aquaculture is important for fish supply. Cage culture has the characteristics of high efficiency, low comprehensive cost, low pollution, excellent water quality, low fish mortality rate and good quality of fish products. However, due to the large water surface range of the net cage, manual feeding is not only uneven, but also labor-intensive. Therefore people have just designed various bait throwing machines that are used for cage culture.

Utility model patent CN 203860240 U discloses a net cage culture bait feeding equipment, which belongs to the field of aquaculture, including a float, a drain, a disc, a suction pipe, a small hole, a drainage pump, a water inlet valve, a rotator and a rotating Rod, the floating ball is installed at the bottom of the disc, and the inside of the floating ball is hollow; the drainage pump is installed on the upper end of the floating ball, and the upper end of the floating ball is provided with a drainage port, and the drainage pump can discharge the water in the floating ball from the drainage port; the bottom of the floating ball There is a water inlet valve, open the water inlet valve to inject water into the floating ball; there are raised edges on the outer edge of the disc, and there are several small holes on the outer edge of the disc, through which the water in the disc can be discharged; The suction pipe is installed in the center of the disc, and the suction pipe is connected with the floating ball; the rotator is installed in the center of the disc, the rotating rod is fixed on the rotator, and the drainage pump can drive the rotator to rotate; the drainage pump and the water inlet valve are controlled by the remote control Control; the floating ball is made of stainless steel, and the disc is made of glass fiber reinforced plastic. The patent can: through the floating ball, the whole device can be lifted and lowered freely in the water. When the water inside the floating ball is discharged, the medium in the floating ball changes from water to air, and the floating ball will float up; when water is injected into the floating ball , due to gravity, the floating ball sinks; the bait can be placed on the disc, and the bait on the disc can sink into the water through the lifting function of the floating ball. Since the bait is always placed on the disc, the bait will not fall from the It leaks out from the mesh of the net cage, and at the same time, the bait that has not been eaten by the fish can be recovered to reduce the pollution of the water body. It is easy to use and easy to operate. However, if the amount of bait on the disk is not enough for the net cage culture bait feeding equipment of this patent, it is necessary to increase the number of times of manual filling of bait, which wastes manpower; churn, making it less than expected delivery depth.

Utility model patent CN 206213013 U discloses a floating underwater bait casting device in a cage, which belongs to the field of bait casting devices, and includes a feeding bin connected to a bait feeding pipeline through a main pipeline, and a bait discharging pipeline is provided on the bait feeding pipeline.
