Fish feed throwing equipment for saline-alkali soil fish pond

Abstract

The invention discloses fish feed throwing equipment for a saline-alkali soil fish pond. The fish feed throwing equipment comprises an air blower and a throwing cylinder, wherein the throwing cylinderis composed of a tail pipe and a head pipe which are communicated with each other; the tail pipe is transversely arranged; the spiral directions of a first spiral blade and a second spiral blade areopposite, so that raw materials located in a feeding tank form circulation flow, feeding is facilitated, and the situation that a discharge port is blocked is avoided; feed is thrown into the fish pond through the action of the air blower, and the amount of the feed falling into the head pipe can be conveniently controlled by controlling the number of intermittent rotation of a rotating wheel; a supporting plate can be stably fixed to the ground through foundation bolts, so that the position of the throwing cylinder is fixed, and shaking is not likely to occur; a rotating handle is rotated bymanpower, when the overlapping number of first magnets and second magnets is different, lifting positions of a moving plate are different, and the inclination angles of the head pipe are also different so that the inclination angles of the head pipe can be conveniently adjusted, and throwing is facilitated.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a fish feed throwing device for fish ponds in saline-alkali land. Background technique [0002] Saline-alkali land is currently the key land for improvement. While the country is vigorously promoting greening improvement and governance, it is also constantly trying new comprehensive improvement methods. In order to comprehensively utilize saline-alkali land, some have established comprehensive experimental areas in saline-alkali land, not only for greenhouse planting , and raised freshwater fish in brackish water, and achieved certain results. Due to the high salt content in the water, it has a good bactericidal effect on some water bacteria in the pond after aquaculture in brackish water, effectively avoiding some of the fish farming. Common lesions, improve the survival rate of fish. [0003] In order to grow the fish quickly and well, it is necessary to feed the fish regula...

AI Technical Summary

Problems solved by technology

[0003] In order to grow the fish quickly and well, it is necessary to feed the fish regularly or irregularly. If the fish feed cannot be eaten by the fish well, the feed will be soaked in water and decomposed, which will easily lead to changes in water quality and reduce the water quality in the pond. Oxygen content, etc., are not conducive to fish growth, and sometimes fish will die due to hypoxia

[0004] The feeding of fish feed mainly relies on manual feeding. Due to limited manpower, the feeding location is often at the edge of the pond, which can easily lead to the accumulation of fish feed in the pond, and the fish feed cannot be evenly dispersed in the pond. This will cause the water in the pond to become turbid, including silt, floating objects, etc. The fish will breathe some impurities into the body during the breathing process, which will cause the fish to get sick; Feeding fishponds with dozens of acres is a very tiring task, time-consuming and labor-intensive
