the cleaning mechanism comprises an air flow channel arranged on the support, and an air inlet and a plurality of air injection holes which are arranged on the support and are respectively communicated with two ends of the air flow channel, the air injection holes are positioned above the screening barrel, and a control valve for controlling the air flow channel to open and close is arranged on the air flow channel; the control valve comprises a valve core which is connected to the support in a sliding mode and penetrates through the air flow channel, an annular groove used for conducting the air flow channel is formed in the side face of the valve core, and a spring used for pushing the valve core to close the air flow channel is installed between the support and the valve core.

2. The system for processing organic fertilizer as claimed in claim 1, wherein the axis of said rotating disk and the axis of said rotating shaft are exactly on the same horizontal line when the upper end surface of said sliding block contacts said rail.

3. The organic fertilizer processing system of claim 2, wherein a connecting line between the end of the push rod close to the column and the central axis of the column forms an included angle with the push rod, and the minimum angle of the included angle is less than 180 degrees.

4. The system for processing organic fertilizer of claim 3, wherein the bottom surface of said pushing rod is parallel to the upper surface of said drying table, the inner bottom surface of said collection box is lower than the upper surface of said drying table, and the mesh of said second screen is smaller than the mesh of said first screen.

5. A method for processing an organic fertilizer by using the organic fertilizer processing system of claim 4, comprising:

s3, drying and collecting fine materials: when the screening barrel screens the organic fertilizer with smaller particles, the push rod is rotated to push the organic fertilizer spread on the drying table to be flat, the heating plate is electrified and heated to dry the particles of the organic fertilizer, and after the drying is finished, the push rod is moved down to be tightly attached to the drying table to push the organic fertilizer on the drying table into the collection box, so that the worker can seal and store the small-particle organic fertilizer bags in the collection box to finish the production of the small-particle organic fertilizer;
