Description

Technical Field

[0001] The invention relates to the technical field of fertilizer screening, in particular to green fertilizer processing and screening equipment. Background Art

[0002] Green fertilizer refers to fertilizer that is environmentally friendly and has little pollution, mainly including organic fertilizer and biological fertilizer. Organic fertilizer is made from animal and plant residues through fermentation and decomposition. It can provide various nutrients needed for plant growth, and can also improve soil structure, increase soil water retention and air permeability. These raw materials may contain plant fibers, such as straw, leaves and other fibrous substances that are not completely broken down during the decomposition process. At the same time, some organic substances may produce sticky secretions or incompletely decomposed colloidal substances during the fermentation process. In addition, in the production process of green fertilizer, some auxiliary materials may be added or specific treatment processes may be carried out, which may also introduce fibrous substances or sticky components. For example, some natural polymer substances that may be added to increase the water retention of fertilizers may bring a certain degree of stickiness.

[0003] At present, the most common screening equipment for fertilizer screening is the drum screening machine. However, fibrous materials often have a certain length and flexibility, and are easily intertwined and entangled on the screen, or stuck in the screen holes, blocking the passage of other particles. At the same time, they may move with the vibration during the screening process, further aggravating the blockage. In addition, the sticky components may cause the fertilizer particles to stick to each other and form clumps. These clumps are easy to block the screen holes and may also adhere to the screen, gradually accumulate, reduce the effective area of ​​the screen holes, and cause the screen holes to be blocked.

[0004] Based on the above situation, we propose a green fertilizer processing and screening equipment to solve the above problems. Summary of the invention

The second driving member 9 drives the rotating rod 92 to rotate, and the screening drum 2 is driven to rotate synchronously under the meshing action of the gear ring 91 and the gear 93, so that the rotation of the screening drum 2 drives the internal fertilizer to move, and the screening work is performed. The lower end of the closing cover 1 can also be provided with a supporting leg 13, and in order to make it easier for the fertilizer in the screening drum 2 to move toward the output end, the screening drum 2 can be tilted downward in the direction of the output end.

[0023] A feeding member 3 for conveying fertilizer to the inside of the screening drum 2 is provided at the input end of the screening drum 2. A pretreatment component for preliminarily treating fibrous materials in the fertilizer is provided inside the feeding member 3. The pretreatment component includes a first rotating shaft 31 rotatably connected to the feeding member 3. The first rotating shaft 31 is connected to a plurality of lifting rods 32 equidistantly arranged along the axial direction of the first rotating shaft 31. A first driving member 33 having an output end connected to one end of the first rotating shaft 31 is provided outside the feeding member 3. The first driving member 33 and the second driving member 9 can both be By using devices such as a servo motor, when the first driving member 33 drives the first rotating shaft 31 to move in a circular motion, the lifting rod 32 is driven to move in a synchronous circular motion in the feeding member 3, thereby lifting the fibrous material mixed in the fertilizer passing through the feeding member 3, reducing the possibility of the fibrous material entering the screening drum 2 and causing it to be intertwined on the screen or stuck in the screen holes. At the same time, some fertilizers that are clumped together can also be broken up by the action of the lifting rod 32, reducing the possibility of the clumped fertilizers clogging the screen holes and improving the subsequent screening effect.

[0024] Reference Figure 7 as well as Fig. 9As shown, further, in order to clean the fibrous substances mixed in the fertilizer entering the screening drum 2 and some of the materials that are adhered to each other, a wind heating component is also provided. The wind heating component is used to blow hot air into the interior of the screening drum 2.
