Device for throwing fish food on water surface

Abstract

The invention relates to a device for throwing fish food on the water surface. The device includes a floating platform, a food storage groove formed in the middle of the upper end face of the floatingplatform, an upper annular discharging turntable arranged on the upper portion of the food storage groove and a vertically fixed material conveying pipe. The lower end of the material conveying pipeis inserted into the food storage groove, and the upper end of the material conveying pipe passes through an inner ring of the upper annular discharging turntable to the upper portion of the upper annular discharging turntable; the circumferential surface of the upper portion of the material conveying pipe is sleeved with an umbrella-shaped upper guide cove; the inside of the material conveying pipe is sleeved with a spiral shaft, the upper end of the spiral shaft is slightly higher than the upper end face of the material conveying pipe, and fish food in the food storage groove is conveyed tothe upper end of the material conveying pipe, falls down, and then guided by the upper guide cover to the upper annular discharging turntable. The upper surface of the upper annular discharging turntable is uniformly provided with several convex first separation strips. The device can achieve automatic feeding and uniformly throw the fish food around.

Description

technical field [0001] The invention relates to a fish food spreading device on the water surface, which belongs to the field of aquatic product cultivation equipment. Background technique [0002] A major problem facing fish farming is the problem of feeding feed. The existing methods generally use artificial feeding, which is a heavy workload, and long-term use will have adverse effects on hand joints, and the range of feeding is limited and cannot be fed. Feed to a longer distance, the feeding effect is not good. At present, some of them use equipment to feed, and the bait is launched on the shore through compressed air. This method has a fixed feeding direction and a rough feeding method. The actual feeding range is also small, and the noise is extremely high. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a fish food spreading device on water surface. The fish food spreading device on the water surfa...

[0002] A major problem facing fish farming is the problem of feeding feed. The existing methods generally use artificial feeding. This method has a large workload, and long-term use will have adverse effects on hand joints, and the range of feeding is limited, so it cannot be fed. Feed to a long distance, the feeding effect is not good

At present, there are also some equipment feeding, and the bait is launched by compressed air on the shore. The feeding direction of this method is fixed, the feeding method is rough, the actual feeding range is also small, and the noise is extremely high.
