Description

Technical Field

[0001] The utility model relates to the technical field of leech cultivation, in particular to a leech cultivation device with an automatic circulating water replenishment function. Background Technique

[0002] Leeches, commonly known as bloodsuckers, leech turtles, meat drills, etc., belong to the phylum Annelida, class Hirudinea, order Gnathobdellida, family Hirudinidae, and are traditional medicinal aquatic animals in many countries around the world.

[0003] With the application and improvement of modern biotechnology, the extraction, processing and medical clinical application of hirudin, as well as the development, research and promotion of Chinese patent medicines, the demand for leeches has increased year by year. At the same time, Japan, South Korea and Southeast Asian countries also import a large amount of leeches from China, resulting in a shortage in the domestic leech market, rising prices. Historically, leech products mainly relied on natural fishing. In recent years, due to the increase in the use of pesticides and fertilizers, as well as the environmental pollution caused by industrial and agricultural "three wastes", coupled with the predatory capture of leeches in recent years, the wild natural resources have decreased sharply. From the perspective of the future development of the pharmaceutical market, the shortage of leech raw materials is difficult to alleviate in the short term, and the contradiction between supply and demand will become increasingly large. Relying on the regeneration of natural resources cannot solve this contradiction. In order to make up for this shortage of natural resources and protect precious and limited wild resources, artificial breeding of leeches is imperative. The huge market demand has created a broad market prospect for the artificial breeding of leeches.

[0004] The main concept of leech cultivation is still to breed in a broad water body, with high cost and low benefit, and it is impossible to directly understand the growth situation of leeches. Content of the Utility Model

[0005] The purpose of the utility model is to provide a leech cultivation device with an automatic circulating water replenishment function. By designing a flowing cultivation environment to simulate the wild growth environment of leeches, the growth cycle of leeches is short and the bait utilization rate is high.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A leech cultivation device with an automatic circulating water replenishment function, including a box body, characterized in that: the box body is a cuboid structure made of ceramics, an insect-proof net is arranged on the top of the box body, a water inlet is arranged on the left side of the box body, a water collecting tank is arranged on the right side of the bottom of the box body, a filter screen is arranged on the top of the water collecting tank, a drain pipe is arranged on the bottom of the water collecting tank, the drain pipe is connected to a sedimentation tank, a biochemical tank is arranged on the right side of the sedimentation tank, a floating tray is arranged on the upper part of the biochemical tank, plants are planted on the floating tray, a clear water tank is arranged on the right side of the biochemical tank, a circulating pipe is arranged on the upper part of the clear water tank, a circulating pump is installed on the circulating pipe, and the other end of the circulating pipe is connected to the water inlet.

[0007] Preferably, a zipper is arranged on the upper part of the insect-proof net.

[0008] Preferably, a cobblestone layer is provided in the middle and lower part of the clear water tank, an activated carbon layer is provided above the cobblestone layer, and a fine sand layer is provided above the activated carbon layer.

[0009] Preferably, a driving motor is provided in the upper right part of the box body, a lead screw is provided on the left side of the driving motor, a sleeve is provided on the upper part of the lead screw, the sleeve can move left and right along the lead screw, a telescopic pipe is provided at the right end of the water inlet, and the telescopic pipe is fixedly connected to the sleeve through a fixing rod.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The present utility model can effectively cultivate leeches, especially has good adaptability to Hirudinaria manillensis. According to the characteristic that leeches like flowing water, clear water is continuously supplemented into the box body to form a flowing water body, which can not only take away various excrements, but also take away the residual bait, preventing the bait from staying in the box body for a long time and causing the bait to deteriorate, thus affecting the living environment of leeches.
