AI Technical Summary
Existing fertilizer screening devices are prone to clumping due to humidity during storage, and lack effective dispersing and cleaning devices, resulting in low screening efficiency and increased labor costs.
A fertilizer dispersion device including an inner dispersion section and an outer dispersion section was designed. The dispersion is achieved by rotating in opposite directions, and a cleaning device is provided to clean the surface of the screen plate and the screen holes to ensure screening quality.
It effectively breaks up clumps of fertilizer, improves screening accuracy and efficiency, reduces manual labor, prevents screen blockage, and ensures the stability of screening quality.
