[0002] The ventilation equipment used in the existing chicken farm is generally common fan equipment, which is used for regulating and controlling the temperature inside the breeding warehouse. The existing fan structure is generally fixed with a motor and a fan in a cylindrical outer frame. The structure is relatively simple. Since a large amount of chicken feathers will be generated inside the chicken farm, a filter screen is generally installed at one end of the fan. The filter screen can filter out chicken feathers when the fan is working. However, since the fan structure is large, the diameter of the filter screen is also large, which is not convenient for cleaning. In addition, the existing fan generally needs to use multiple expansion bolts to fix it in the factory building during installation, which is troublesome to install and inconvenient to disassemble and maintain. SUMMARY

[0003] The utility model solves the technical problem that the filter screen in the existing fan for chicken farm is not convenient to clean, and the fan as a whole is not convenient to install and disassemble.

[0004] To solve the above problems, the utility model adopts the technical scheme of a ventilation device for chicken farm, which comprises a fan body. A background plate is fixed on one side of the fan body. A filter screen plate is fixed at the air inlet of the fan body by screws. A plurality of connecting shafts are rotatably arranged at the edge of the filter screen plate on one side of the background plate. An arc-shaped soft scraper is fixed on the side surface of the connecting shaft. A pulley is fixed at one end of the connecting shaft through the background plate. A transmission belt is sleeved outside the pulley. An installation frame is fixed outside the fan body. Through holes are formed in both sides of the installation frame. An installation block is inserted into the through hole. A connecting plate is fixed on one side of the installation block inside the installation frame. Telescopic rods are fixed on the inside of the installation frame at the upper and lower positions. One end of the telescopic rod is fixed to one side of the connecting plate.

[0005] As a further scheme of the utility model, a motor is fixed on the top of the installation frame. The output end of the motor is fixed on one side of a pulley, which is used to drive the rotation of the connecting shaft.

[0006] As a further scheme of the utility model, the plurality of connecting shafts are four in total. The two longitudinal connecting shafts are in the same group. The connecting shafts in the same group have the same direction. The connecting shafts on the left side of the background plate rotate counterclockwise, and the connecting shafts on the right side of the background plate rotate clockwise, which is convenient for scraping the dirt or hair from bottom to top.

[0007] As a further scheme of the utility model, a collection box is fixed on one side of the background plate near the edge, which is used to collect the dirt and hair scraped off by the arc-shaped soft scraper.

[0008] As a further scheme of the utility model: motor, telescopic rod, fan body are all electrically connected with external power supply.

[0009] The utility model discloses compared with prior art has the advantages that: this patent increases arc soft scraper structure, can in time with the chicken feather or other sundries that remain in filter screen board one side hang, then drive sundries or chicken feather and enter the collection box and collect, increase the mounting block structure, can directly with mounting block plug in the installation groove that realizes good, is convenient and fast when installing.
