[0002] After fermentation, the fertilizer presents a caked state. In the existing production process, generally, the caked fertilizer is directly broken up and pulverized, and then the granular impurities therein are screened out. However, there are still many straws in the fertilizer that are not completely decomposed, and even long strips of plastics remain. Therefore, it is necessary to preliminarily screen the fertilizer before pulverizing and granulating the fertilizer to screen out impurities such as straws.

[0003] Chinese Patent Publication No. CN219560444U discloses an organic fertilizer impurity removal device, including a base. The top of the base is slidably connected with a mounting plate. A vibration motor is fixedly installed on the top of the base. The end of the output shaft of the vibration motor is fixedly connected with the side wall of the mounting plate. A sliding mechanism is arranged on the front side wall of the mounting plate. The technical solution has a reasonable structural design. When removing impurities from the organic fertilizer, it can automatically clean the sundries gathered on the screen plate, and when cleaning the sundries, it can automatically close the placing hopper, eliminating the need for manual cleaning by the operator and reducing the working intensity of the operator.

[0004] However, the above technical solution has the following deficiencies: When using the device to remove impurities from the fertilizer, some fertilizers that have not yet fallen through the screen plate will be cleaned up together, resulting in waste of fertilizer and increasing the production cost of fertilizer. Summary of the Utility Model

[0005] The purpose of the utility model is to address the problems in the background technique and propose a fertilizer impurity removal device that filters impurities in the fertilizer multiple times through a first filter rack and a second filter rack to reduce fertilizer loss during impurity removal.

[0018] Embodiment 1

[0019] As Figures 1 - 3 shown, a fertilizer impurity removal device proposed in this embodiment includes an impurity removal box 1 and a screening assembly. The impurity removal box 1 has an impurity removal chamber 101. A blanking hopper 2 is arranged at the top of the impurity removal box 1, and the blanking hopper 2 is communicated with the impurity removal chamber 101. A discharging frame 14 is arranged at the bottom of the impurity removal box 1. The screening assembly is arranged in the impurity removal box 1. The screening assembly includes a first filter frame 10 and a second filter frame 11 that are inclined and slidably arranged in the impurity removal box 1, a driving frame 12 arranged on the second filter frame 11, and a vibration motor 13 arranged in the impurity removal box 1. The first filter frame 10 and the second filter frame 11 are connected. The first filter frame 10 is located above the second filter frame 11. The first filter frame 10 slopes downward from one side towards one side of the second filter frame 11. The vibration motor 13 is drivingly connected to the driving frame 12. Both the first filter frame 10 and the second filter frame 11 are located above the discharging frame 14.

[0020] When this embodiment is used, workers pour fertilizers into the blanking hopper 2, and the fertilizers flow from the blanking hopper 2 into the first filter frame 10 in the impurity removal box 1. The vibration motor 13 drives the driving frame 12 to move reciprocally. The driving frame 12 drives the second filter frame 11 and the first filter frame 10 to move reciprocally. When the fertilizers are shaking reciprocally, they fall from the first filter frame 10. The sundries and the fertilizers wrapped by the sundries will roll onto the second filter frame 11 under the action of their own gravity, and then the sundries are cleaned for the second time. Finally, the sundries will fall to the ground under the action of their own gravity, and the separated fertilizers will fall onto the discharging frame 14 and roll into a container pre-placed by the user, thereby reducing the loss before fertilizer processing and reducing the production cost of fertilizers.

[0021] Embodiment 2

[0022] As Figures 1 - 3As shown in the figure, a fertilizer impurity removal device proposed in this embodiment, compared with Embodiment 1, in this embodiment, a material guiding block 9 is provided on the feeding hopper 2. The material guiding block 9 has a material guiding hole. The material guiding block 9 slopes downward gradually from the edge of the material guiding block 9 towards the edge of the material guiding hole. A fixing frame 3 and a driving component are provided on the feeding hopper 2. A spiral conveyor blade 8 is rotatably arranged on the fixing frame 3 and the material guiding block 9. The top of the fixing frame 3 slopes from the middle to both sides, so that fertilizers will not remain on the fixing frame 3, thus avoiding the need for workers to clean the device after the processing is completed.

[0023] The driving component includes a motor 4 arranged on the feeding hopper 2, a synchronous pulley a 5 arranged at the output end of the motor 4, a synchronous pulley b 6 coaxially arranged on the spiral conveyor blade 8, and a synchronous belt 7 arranged on the synchronous pulley a 5 and the synchronous pulley b 6. A plurality of cleaning blocks are arranged on the feeding hopper 2. All the cleaning blocks are in frictional contact with the synchronous belt 7, and the cleaning blocks clean the fertilizers adhered to the synchronous belt 7, thereby reducing the loss of fertilizers before processing.

[0024] When this embodiment is in use, fertilizers fall into the feeding hopper 2. The motor 4 drives the synchronous pulley a 5 to rotate. The synchronous pulley a 5 drives the synchronous pulley b 6 to rotate through the synchronous belt 7. The synchronous pulley b 6 drives the spiral conveyor blade 8 to rotate stably. The fertilizers are quantitatively sent to the first filtering rack 10 by the spiral conveyor blade 8, so that the filtered fertilizers are within the bearing range of the first filtering rack 10.
