Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing technology, and in particular to a screening device for bio-organic fertilizer. Background Technology

[0002] Bio-organic fertilizer refers to a type of fertilizer that combines the effects of microbial fertilizer and organic fertilizer by combining specific functional microorganisms with organic materials mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) that have undergone harmless treatment and composting. During the production and processing of bio-organic fertilizer, the fertilizer needs to be screened.

[0003] A screening device for bio-organic fertilizer disclosed in announcement number CN218360626U solves the problems of a large amount of dust generated during the screening process, affecting air quality, and the difficulty in adjusting the height of the screen. If the screen is too high, it is inconvenient to put fertilizer onto the screen, wasting physical effort; if the screen is too low, it is inconvenient to remove the material screened below the screen.

[0004] However, the screening device for this bio-organic fertilizer has the following disadvantages: during the screening process, organic fertilizer particles are easily blocked in the mesh, affecting subsequent screening. In addition, it is not convenient to grind the large organic fertilizer particles screened out, which need to be removed and processed by other equipment, resulting in low work efficiency.

Through the setting of the grinding mechanism 4, after screening, large particles of fertilizer are screened out on the screening screen assembly 6. The hydraulic cylinder 3 is opened, which drives the grinding mechanism 4 to press down. The servo motor 4 drives the grinding disc 402 to grind the screened large particles of fertilizer. After grinding, screening continues. Grinding and screening are carried out in the same equipment, which improves work efficiency.

When the bio-organic fertilizer is put into the screening barrel 1 through the anti-blocking mechanism 7, the vibration motor 5 is powered on and drives the screening barrel 1 to vibrate, thus screening the bio-organic fertilizer. The cylinder 701 is opened, which drives the rubber ball 702 to repeatedly strike the bottom of the screening mesh assembly 6, shaking off the fertilizer stuck in the mesh of the screen 602, thus avoiding the mesh from being blocked and affecting the screening.

Open the cylinder 701 and drive the rubber ball 702 to repeatedly hit the bottom of the screening mesh assembly 6 to shake off the fertilizer stuck in the mesh of the screen 602 and avoid the mesh from being blocked and affecting the screening.

[0042] The second step: After screening, large fertilizer particles are screened out on the screening screen assembly 6. The hydraulic cylinder 3 is opened to drive the grinding mechanism 4 to press down. The A servo motor 4 drives the grinding disc 402 to grind the large fertilizer particles screened out. After grinding, screening continues. Grinding and screening are carried out on the same equipment, which improves work efficiency.

[0043] The third step: The screened bio-organic fertilizer falls into the hopper 8 and enters the discharge pipe 9. After the B servo motor 1001 is powered on, it drives the auger rod 1002 to rotate, and the fertilizer is quickly discharged.
