[0024] Hereinafter, embodiments of the screening device for the organic fertilizer fermentation of the present utility model will be described with reference to the drawings.

[0025] Figures 1-7A screening device for fermented organic fertilizer showing an embodiment of the present utility model, which includes a housing 1: a floor stand 2 is arranged on the surface of the housing 1, a feeding port 3 is fixedly installed in the inner cavity of the floor stand 2, a support frame 4 is fixedly connected in the inner cavity of the housing 1, four corners of the top of the support frame 4 are fixedly connected with fixing blocks 5, a first fixing column 6 is fixedly connected to the top of the fixing block 5, a screening box 8 is arranged on the top of the support frame 4, two symmetric triangular fixing blocks 9 are fixedly connected to the front and rear sides of the screening box 8, a second fixing column 10 is fixedly connected to the bottom of the triangular fixing block 9, a spring 7 is sleeved on the surfaces of the first fixing column 6 and the second fixing column 10, and both ends of the spring 7 are fixedly welded to the fixing block 5 and the triangular fixing block 9 respectively. A fixing frame 11 is fixedly connected to the middle axis of the bottom of the screening box 8, and two symmetric vibration motors 12 are fixedly installed at the bottom of the fixing frame 11. Four slide rails 13 are fixedly connected in the inner cavity of the screening box 8. A large-diameter screen 14 is slidably connected to the inner walls of the upper two slide rails 13, and a small-diameter screen 15 is slidably connected to the inner walls of the lower two slide rails 13. Screws 17 are threadedly connected to the tops of the four slide rails 17, and the bottoms of the screws 17 are in close contact with the large-diameter screen 14 and the small-diameter screen 15 respectively. Through the arrangement of the screws 17, it plays a role in limiting the placement of the large-diameter screen 14 and the small-diameter screen 15 between the four slide rails 13, avoiding vibration during the operation of the screening box 8, causing the large-diameter screen 14 and the small-diameter screen 15 to deviate from the inner walls of the slide rails 13, and improving the stability of the large-diameter screen 14 and the small-diameter screen 15. The right side of the screening box 8 is rotatably connected to a discharge box 16 through a rotating shaft, the rear side of the discharge box 16 is rotatably connected to a rotating pin 18 through a rotating shaft, a bolt 19 is threadedly connected to the rear side of the rotating pin 18, and the bolt 19 penetrates through the surface of the rotating pin 18 and is threadedly connected to the screening box 8. Through the arrangement of the rotating pin 18, it plays a role in limiting the discharge box 16 during the merging process with the screening box 8, and improves the stability of the discharge box 16. A hole for feeding organic fertilizer is opened at the top of the screening box 8, and the feeding port 3 is communicated with the hole at the top of the screening box 8. A groove for the bolt 19 to penetrate through is opened at the rear side of the screening box 8. Through the arrangement of the hole opened at the top of the screening box 8, the organic fertilizer falling from the inner cavity of the feeding port 3 can effectively fall on the top of the large-diameter screen 14, and then all the organic fertilizer passes through the inner cavity of the screening box 8 and falls into the discharge port.

[0026] Working principle: When the utility model is in use, the user first pours the organic fertilizer into the inner cavity of the feeding port 3. Then, the organic fertilizer enters the inner cavity of the screening box 8 through the feeding port 3. Subsequently, the vibration motor 12 is turned on. Since the vibration motor 12 is a vibration motor, it will vibrate itself, driving the screening box 8 to vibrate. The spring 7 will undergo elasticity, causing the screening box 8 to shake up and down. As a result, the organic fertilizer will leak through the diameter opening of the large-diameter screen 14 onto the top of the small-diameter screen 15. Furthermore, organic fertilizers of different particle sizes will fall at different channel openings. Due to the inclined vibration of the screening box 8, the organic fertilizer will slide from left to right to the discharge port inside the fixed column 1. Thus, the vibration of the screening box 8 causes the screened organic fertilizer to leak out from the discharge port inside the fixed column 1. When the screening of the organic fertilizer is completed, the bolt 19 is removed, and the rotation pin 18 is rotated to open the discharge box 16. Then, the screw 17 is removed, and the large-diameter screen 14 and the small-diameter screen 15 inside the screening box 8 are disassembled for cleaning.

[0027] In summary: For the screening device used for the fermented organic fertilizer, through the combined use of the vibration motor 12, the large-diameter screen 14, and the small-diameter screen 15, the organic fertilizer leaks out from different discharge ports inside the discharge box 16. Through the combined use of the slide rail 13, the screw 17, and the rotation pin 18, the large-diameter screen 14 and the small-diameter screen 15 can be disassembled and taken out. It can achieve the purpose of adopting an inclined screening operation structure and a detachable screen structure, enabling organic fertilizers of different particle sizes to leak out from different discharge ports, effectively avoiding the phenomenon of untimely disassembly and cleaning of the screen, and thus improving the screening quality of the organic fertilizer and the cleaning efficiency of the screen.
