Microorganism feeding device for improving water quality of aquaculture water body

The utility model relates to the technical field of biology and ecology, in particular to a microorganism feeding device for improving the water quality of an aquaculture water body. Comprising a ship body, a connecting block is hinged to one side of the ship body, a throwing depth control device is arranged on the connecting block, and an automatic and uniform microorganism throwing mechanism is arranged below the throwing depth control device. The device is simple to operate, microorganism raw materials can be driven to be quantitatively fed only by moving the ship body and driving the propeller to rotate, deep feeding can be freely controlled, and the situation that microorganisms suddenly die in an environment with uncomfortable temperature, and the treatment effect is affected is avoided. 本实用新型涉及生物生态技术领域，尤其涉及一种用于改良养殖水体水质的微生物投放装置。包括船体，所述船体一侧铰接设有连接块，所述连接块上设有投放深度控制装置，所述投放深度控制装置下设有微生物自动均匀投放机构。本实用新型通过操作简单，只需要船体移动起来，带动螺旋桨旋转就能带动微生物原料定量的进行投放，能够自由控制深度投放，避免微生物在温度不适的环境内突然死亡，影响治理效果。
