It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0023] A fertilizer filtering induced draft fan provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0024] Combination Figure 1-4 As shown, the utility model provides a fertilizer filtering induced draft fan, including a blower 1, one side of the blower 1 is fixedly connected with a pipe 2 in a connected shape, the inner wall of the pipe 2 is fixedly connected with a fixing ring 3, the center position of one side of the fixing ring 3 is rotatably connected with a rotating shaft 4, one end of the rotating shaft 4 is fixedly connected with a fan 5, one end of the rotating shaft 4 is fixedly connected with a protrusion 6, the bottom of the protrusion 6 is fitted and slidably connected with a moving block 7, the bottom of the moving block 7 is symmetrically fixedly connected with a pushing block 8, one side of the pushing block 8 is fitted and slidably connected with an extruding block 9, one side of the extruding block 9 is fixedly connected with a moving rod 10, one end of the moving rod 10 is fixedly connected with a fixing block 11, one side of the fixing block 11 is rotatably connected with a cleaning rod 12, and the outer wall of the cleaning rod 12 is fitted and slidably connected with a filter screen 14;

[0025] The fixed block 11 is fixedly connected to one end of the moving rod 10 in sequence, and the number of the fixed blocks 11 is six. The number of the cleaning rods 12 corresponds to the number of the fixed blocks 11. One end of the moving rod 10 is fixedly connected to a spring 13, and one end of the spring 13 is fixedly connected to the inner wall of the filter screen 14. There are two extrusion blocks 9, and the number of the moving rods 10 corresponds to the number of the extrusion blocks 9. One end of the pipeline 2 is fixedly connected to a box body 19 in a connected state, and a placement box 20 is fixedly connected to the inner wall of the box body 19. A door panel 21 is provided on one side of the box body 19.

[0026] In the first embodiment, when the blower 1 extracts gas to filter the fertilizer, the airflow drives the fan 5 to rotate. When the fan 5 rotates, it can drive the protrusion 6 on the rotating shaft 4 to rotate. When the protrusion 6 rotates, it can squeeze the moving block 7 to move. The movement of the moving block 7 can drive the pushing block 8 to push the squeezing block 9, and then drive the moving rod 10 to move. When the moving rod 10 moves, it can drive the cleaning rod 12 on the fixed block 11 to clean the filter screen 14. In this way, the filter screen 14 will not be blocked, thereby ensuring the quality of the fertilizer during production and processing, and reducing the number of cleaning times, thereby ensuring the efficiency of production and processing.

[0027] A motor 15 is fixedly connected to one side of the blower 1, a rotating rod 16 is fixedly connected to one end of the motor 15, a fan blade 17 is fixedly connected to the outer wall of the rotating rod 16, and a cleaning rod 18 is rotatably connected to one end of the fan blade 17.

The number of the fan blades 17 is eight to ten, and the number of the cleaning rods 18 corresponds to the number of the fan blades 17.

[0028] In the second embodiment, when the fertilizer impurities are adsorbed, they will definitely fall into the blower 1. If the accumulation time is too long, the internal gas circulation of the blower 1 will be restricted, the air circulation speed will slow down, and then affect the filtration of the fertilizer. Cleaning by the cleaning rod 18 on the fan blade 17 can avoid the accumulation of impurities, thereby ensuring the normal use of the blower 1.

[0029] The working principle and use process of the utility model are as follows: when the blower 1 rotates, the fan blades 17 rotate to form an airflow, and at the same time, the cleaning rod 18 can be driven to clean the inner wall of the blower 1. When the gas flows, the fan 5 can be driven to rotate. When the fan 5 rotates, the rotating shaft 4 can be driven to rotate. When the rotating shaft 4 rotates, the protrusion 6 can be driven to rotate. When the protrusion 6 rotates, it can push the push block 8 on the moving block 7 to move. The push block 8 drives the extrusion blocks 9 on both sides to move, and then drives the fixed block 11 on the moving rod 10 to move. The movement of the fixed block 11 can drive the cleaning rod 12 to clean the filter 14 to avoid blockage.
