Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer production, in particular to a multi-stage screening device for organic fertilizer. Background Art

[0002] Screening structures generally play multiple roles in the production of organic fertilizers, including screening and removing impurities, grading finished products, improving production efficiency, reducing labor intensity, and protecting the environment. These roles collectively promote the automation, efficiency, and environmental friendliness of organic fertilizer production.

[0003] However, the inclination angle of the existing screening structure is fixed, and it can only screen fixed organic fertilizer raw materials. Since different types of organic fertilizer raw materials have different water contents, different types of organic fertilizer raw materials need to use screening structures with different inclination angles when screening. This results in the need to replace the screening structure with the corresponding inclination angle when screening different types of organic fertilizer raw materials, which is very troublesome. Utility Model Content

[0004] Therefore, the present invention provides a novel multi-stage screening device for organic fertilizer, which has solved the above-mentioned problems.

[0005] In order to accomplish the above objectives, the utility model provides an organic fertilizer multi-stage screening device, including an adjustment structure and a screening structure;

[0006] The adjusting structure includes a base plate, an adjusting plate, a hinge rod, and a driving member. Rotating rods are respectively provided on both sides of the front end of the adjusting plate. The lower end of the rotating rod is rotatably connected to the base plate. An opening is provided in the middle of the adjusting plate. The rear end of the adjusting plate is respectively hingedly connected to the upper end of the hinge rod. The lower ends of the two hinge rods are respectively hingedly connected to the upper end of the moving block. The two moving blocks are respectively movably provided in grooves on both sides of the rear end of the base plate. The driving member is used to drive the moving block to move.

[0007] The screening structure is arranged in the opening, and the screening structure includes an annular screen and a rotating member.

The annular screen has a first filter section and a second filter section. A first outlet is provided below the first filter section, a second outlet is provided below the second filter section, and a third outlet is provided below the front end of the annular screen.

[0008] The above beneficial effects are as follows: the driving member drives the moving block to move in the direction of the rotating rod in the groove, and the moving block drives the lower end of the hinged rod to move. At this time, the rear end of the adjusting plate is moved upward by the action of the hinged rod, and the rotating rod at the front end of the adjusting plate is rotated downward. At this time, the inclination angle of the screening structure will become larger, or the driving member drives the moving block to move in the direction away from the rotating rod in the groove, and the moving block drives the lower end of the hinged rod to move. At this time, the rear end of the adjusting plate is moved downward by the action of the hinged rod, and the rotating rod at the front end of the adjusting plate is rotated upward. At this time, the inclination angle of the screening structure becomes smaller or is in a horizontal state. By adjusting the angle of the screening structure, different types of organic fertilizer raw materials can be screened, which is very convenient.

[0009] A preferred solution is that the driving member includes a screw rod and a first motor, the screw rod is arranged in the groove, and the first motor is connected to the screw rod.
