This invention relates to the field of leech farming
greenhouse technology, and discloses a dimmable and escape-preventing leech farming
greenhouse, comprising several ground stakes, with a column fixedly installed on the top of each ground stake, and a shielding component installed on the column; an installation mechanism, which is disposed on the column, and installs the shielding component through an installation shell, a winding reel, a fixing shell, and a pressure plate; by setting up the installation mechanism, the shielding component slides in the column groove on both sides through sliding blocks, and is pressed tightly by the pressure plate and ball bearings, ensuring a seamless seal throughout the process, reducing the escape of leeches through gaps. The shielding component integrates a rainproof film, a sunshade cloth, and an escape-preventing net into a single unit using high-frequency
welding, replacing the traditional separate structure, and simultaneously achieving dimming, rain protection, and escape prevention, adapting to the low-light growth habits of leeches, making operation more efficient, and by setting up multiple
layers of shielding components, the dimming can be quickly adjusted by increasing or decreasing the number of shielding components.
