Indoor high-yield leech culture tank

Abstract

The invention discloses an indoor high-yield leech culture tank. The indoor high-yield leech culture tank comprises a leech culture tank, an oxygenating pipe and a water change device, wherein the oxygenating pipe is arranged above the leech culture tank, and the leach culture tank is arranged as a square water tank. A plurality of protruding columns perpendicular to the bottom surface are dispersively arranged at the bottom of the leech culture tank. The water change device comprises a water inlet upper-limit liquid level switch, an electromagnetic water valve, a water inlet lower-limit water level switch, a water inlet pipe, a water suction liquid-level switch, a water suction pump and a water outlet pipe, which are arranged in the leech culture tank. The electromagnetic water valve is arranged on the water inlet pipe, the water inlet upper-limit liquid level switch and the water inlet lower-limit water level switch are connected with the electromagnetic water valve, and the water suction liquid-level switch is connected with the water suction pump arranged on the water outlet pipe. The indoor high-yield leech culture tank is small and convenient to feed and manage, water change is controlled at fixed time, manual operation is omitted, a great quantity of labor resources is saved, and time and labor are saved. The indoor high-yield leech culture tank is simple and convenient to maintain.

Description

technical field [0001] The invention relates to the field of breeding ponds, in particular to an indoor breeding pond for high-yield leeches. Background technique [0002] Leech is a social animal that avoids light and prefers shade, and is resistant to hunger. It aims at the living habits, behavioral habits, physiological habits, growth habits and climate environment of leeches in nature. Leech is a rare and precious Chinese medicinal raw material that is in short supply at home and abroad. It can treat bruises, high blood pressure, coronary heart disease and tumors. Its medicinal value determines its future market status. From the perspective of the consumer market, my country is the earliest country to use leeches. With the development of domestic medicine and the further development of the medicinal value of leeches, the demand for leeches is increasing day by day. In addition, Europe and the United States have a large consumer market, and Japan, North Korea, and Southe...

Problems solved by technology

However, in recent years, due to the large-scale use of pesticides, chemical fertilizers and pollution of the chemical industry, wild resources have declined sharply, and the medicinal uses of leeches have been continuously explored, resulting in a prominent contradiction between market supply and demand, creating a broad market prospect for artificial breeding of leeches

[0003] Existing leeches are usually cultured in external ponds during the breeding process. This method usually causes leeches to increase or decrease production due to external weather influences and external various birds during breeding, which has a greater impact

Moreover, the densely farmed leeches are of different sizes and of poor quality

When cultivating in external ponds, it is inconvenient to replace water resources and difficult to operate
