[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] This utility model embodiment provides a screening system for processing bio-organic fertilizer, such as Figure 1-2 As shown, the device includes a screening drum 1, which is a hollow cylindrical structure open at both ends. A first drive shaft 2 is coaxially mounted inside the screening drum 1. The first drive shaft 2 is also a hollow tubular structure open at both ends. The first drive shaft 2 is fixedly connected to the screening drum 1 via a mounting bracket 3. A second drive shaft 4 is movably mounted inside the first drive shaft 2. A crushing hammer 5 is mounted on the side wall of the second drive shaft 4. A first driven bevel gear 6 is coaxially mounted on the first drive shaft 2, and a second driven bevel gear 7 is coaxially mounted on the second drive shaft 4. The first driven bevel gear 6 and the second driven bevel gear 7 respectively mesh with a driving bevel gear 8. The driving bevel gear 8 is used to drive the [device / device]. A rotating drive device 9 is connected. The drive device 9 is an electric motor, hydraulic motor, or pneumatic motor. When screening the bio-organic fertilizer, the drive device 9 can drive the active bevel gear 8 to rotate. The active bevel gear 8 can drive the first driven bevel gear 6 and the second driven bevel gear 7 to rotate in different directions. The first driven bevel gear 6 and the second driven bevel gear 7 can respectively drive the first drive shaft 2 and the second drive shaft 4 to rotate in different directions. The first drive shaft 2 and the second drive shaft 4 can respectively drive the screening drum 1 and the crushing hammer 5 to rotate in opposite directions, so as to crush the clumped bio-organic fertilizer during the screening process, and the crushing effect is good.

[0016] It should be noted that the first drive shaft 2 includes two shafts that are coaxially arranged at both ends inside the screening drum 1, and the two ends of the second drive shaft 4 are respectively movably arranged inside the two first drive shafts 2. At the same time, the crushing hammer 5 is installed on the middle side wall of the second drive shaft 4.

[0017] In this embodiment, the screening system further includes a frame 10, on which a hopper 11 is mounted. The bottom of the hopper 11 is divided into a first chamber 111 and a second chamber 112 by a partition. A screening roller 1 is inclinedly disposed above the first chamber 111, and the opening at the lower end of the screening roller 1 is located above the second chamber 112. The bottom of the first chamber 111 is provided with a first discharge port 113, and the bottom of the second chamber 112 is provided with a second discharge port 114. When screening the bio-organic fertilizer, the bio-organic fertilizer can pass through the screening... The bio-organic fertilizer is added to the screening drum 1 through the opening at the upper end of the drum 1 for screening. The bio-organic fertilizer screened through the screening drum 1 can enter the first chamber 111 and be discharged from the first chamber 111 through the first discharge port 113. The unscreened bio-organic fertilizer or impurities in the screening drum 1 can be discharged from the screening drum 1 through the opening at the lower end of the screening drum 1. The discharged bio-organic fertilizer or impurities can enter the second chamber 112 and be discharged from the second chamber 11 through the second discharge port 114.

[0018] In this embodiment, the screening system also includes a roller brush 12 disposed on the outer wall of the screening drum 1. The central axis of the roller brush 12 is parallel to the central axis of the screening drum 1. A driven pulley 13 is coaxially mounted on the roller brush 12. The driven pulley 13 is connected to the driving pulley 15 via a belt 14. The driving pulley 15 is coaxially mounted on the second drive shaft 4. When the second drive shaft 4 rotates, it can drive the driving pulley 15. The driving pulley 15 can drive the driven pulley 13 to rotate via the belt 14. The driven pulley 13 can drive the roller brush 12 to rotate, thus cleaning the screening drum 1 and preventing the bio-organic fertilizer from clogging the screening drum 1 during the screening process. At the same time, by adopting the above driving method, the rotation direction of the roller brush 12 can be the same as the rotation direction of the second drive shaft 4. Since the rotation direction of the second drive shaft 4 is opposite to the rotation direction of the first drive shaft, the rotation direction of the roller brush 12 can be opposite to the rotation direction of the screening drum 1, thereby improving the cleaning effect on the screening drum 1.

[0019] It should be noted that the opposite ends of the two first drive shafts 2 are mounted on the frame 10 through the first bearing 16, the two ends of the second drive shaft 4 extend from the inside of the two first drive shafts 2 and are mounted on the frame 10 through the second bearing 17 respectively, and the two ends of the roller brush 12 are mounted on the frame 10 through the third bearing 18 respectively.

[0020] Specific principle: When screening the bio-organic fertilizer, the bio-organic fertilizer is added into the screening drum 1 through the opening at the upper end of the screening drum 1. The drive device 9 drives the active bevel gear 8 to rotate. The active bevel gear 8 drives the first driven bevel gear 6 and the second driven bevel gear 7 to rotate in different directions. The first driven bevel gear 6 and the second driven bevel gear 7 drive the first drive shaft 2 and the second drive shaft 4 to rotate in different directions, respectively. The first drive shaft 2 and the second drive shaft 4 drive the screening drum 1 and the crushing hammer 5 to rotate in opposite directions, so as to crush the clumps of bio-organic fertilizer during the screening process. The bio-organic fertilizer screened through the screening drum 1 can enter the first chamber 111 and be discharged from the first discharge port 113. The unscreened bio-organic fertilizer or impurities in the screening drum 1 can be discharged from the screening drum 1 through the opening at the lower end of the screening drum 1. The discharged bio-organic fertilizer or impurities can enter the second chamber 112 and be discharged from the second discharge port 114.
