Description

Convenient dismouting structure of air return cloth cover is prevented to poultry fan Technical Field The utility model relates to the technical field of air distribution cover installation, in particular to a convenient dismounting structure of an air return prevention cloth cover of a livestock fan. Background In the livestock-raising industry, good ventilation system is one of the key factors of guaranteeing healthy growth of livestock, and ventilation is carried out through installing the fan, can effectively control the temperature, humidity and the air quality of breeding environment, and the mosquito and fly are many in summer, and when the fan is in the shut-down state, the fan is the passageway that most likely gets into the mosquito and fly, leads to indoor mosquito increase. At present, the cloth cover of the air gathering barrel is fixed on the main body frame of the fan in a sticky mode, and the cloth cover can be tightly attached to the air gathering barrel outer opening under the action of return air, so that the entering path of mosquitoes and flies is greatly reduced. However, by adopting the mode, the fans in the large-scale cultivation place are numerous, and a great deal of labor and time cost are required for maintenance or replacement of the cloth cover each time, so that the efficient management and operation of the cultivation place are not facilitated. Disclosure of utility model The utility model aims to provide a convenient dismounting structure of a livestock fan air return prevention cloth cover, and aims to solve the problems that a large number of fans are needed in a large-scale cultivation place in the prior art, a large amount of manpower and time cost are required to be consumed for maintenance or replacement of the cloth cover each time, and efficient management and operation of the cultivation place are not facilitated. The utility model provides a convenient dismounting structure of a livestock fan anti-return air cloth cover, which comprises a fan main body frame and a mounting connection unit, wherein the mounting connection unit comprises a rectangular plate, a sliding rail, an arc-shaped seat, a trapezoidal rod, a threaded rod, a knob frame, a protection component and a supporting component, the mounting connection unit is connected with the fan main body frame, the rectangular plate is fixedly connected with the fan main body frame and is positioned on the outer side wall of the fan main body frame, the sliding rail is fixedly connected with the rectangular plate and is positioned on the inner side wall of the rectangular plate, the arc-shaped seat is in sliding connection with the sliding rail and is positioned on the inner side wall of the sliding rail, the trapezoidal rod is fixedly connected with the arc-shaped seat and is positioned above the arc-shaped seat, the threaded rod is in threaded fit with the threaded rod, the knob frame is fixedly connected with the threaded rod and is positioned above the threaded rod, the threaded rod is provided with a trapezoidal hole, the trapezoidal hole is in running fit with the trapezoidal rod, the protective component is arranged on the inner side wall of the fan main body frame and is connected with the fan main body frame.
