Automatic dripper screening device

The utility model provides an automatic dripper screening device comprising a rotating round tower, wherein a rotating goods platform is fixedly connected with the rotating round tower and is connected with a screening table with a clamping ring through a smooth inclined surface; high pressure air ports are evenly formed above the screening table in the peripheral direction and are connected with an air pressure gun; the clamping ring is of a one-step structure; the height of the step is matched with a screening table of a dripper. When the position of the dripper is incorrect, the screening table of the dripper can not enter the clamping ring, then the position of the dripper is higher than the correct position, high-speed air flow can blow the dripper at the incorrect position out of the screening table easily, and therefore the positions of drippers on the screening table are correct. The automatic dripper screening device can automatically screen the drippers for operation, the direction of the front face
