Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of screening devices, specifically a fertilizer screening device. Background Technology
[0002] Organic fertilizer refers to a type of fertilizer made from various animal wastes (including animal manure and animal processing waste) and plant residues (oilseed cake, crop straw, fallen leaves, dead branches, peat moss, etc.) through physical, chemical, biological, or a combination of these technologies, using specific processing techniques to eliminate harmful substances and achieve harmless standards. The production process of organic fertilizer includes fermentation, drying, crushing, screening, and bagging. The screening process typically uses organic fertilizer screens or organic fertilizer screening machines.
[0003] In actual use, the applicant found that some fertilizers with high moisture content may appear during the screening process due to air humidity or other reasons. As a result, the fertilizers are discharged slowly and unstablely when guided by the discharge hopper, and they are extremely easy to stick to the inner wall of the discharge hopper, thus affecting the subsequent screening and discharge of fertilizers. In order to solve the above-mentioned problems, a fertilizer screening device is provided. Utility Model Content

Each of the support legs is fixedly connected with a support, and a spring is connected between the support and the support plate. A vibration motor is fixedly installed on the discharge hopper, and a telescopic cloth cover is provided around the connection between the support plate and the machine casing.
[0007] In a preferred embodiment, the bottom of the housing is provided with a feeding port.
[0008] In a preferred embodiment, the screening assembly includes two supports, a drive motor, and a rotating shaft. The supports are fixedly installed on both sides of the housing. A circular frame is fixedly connected to the rotating shaft. A cylindrical screen for fertilizer is fixedly installed on the outside of the circular frame. Shaft seats are rotatably installed on both sides of the rotating shaft. The shaft seats are fixedly installed on one of the supports. The drive motor is fixedly installed on the support, and the output shaft of the drive motor is connected to the rotating shaft.
[0009] In a preferred embodiment, both the housing and the cylindrical screen are designed to be inclined.
[0010] In a preferred embodiment, the cylindrical screen is provided with different apertures, and the cylindrical screen is divided into several segments according to the aperture.
[0011] In a preferred embodiment, a return hopper is fixedly connected to one side of the pallet.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0013] In this invention, a vibrating motor and a spring are used to drive the discharge hopper and pallet to vibrate during discharge. The vibration force reduces the possibility of fertilizer with high water content adhering to the discharge hopper, thereby improving the stability and efficiency of screening and discharge.

Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] The following will combine Figures 1-2 A fertilizer screening device according to an embodiment of the present invention will be described in detail. Example
[0019] This utility model provides a fertilizer screening device, which is referenced in the embodiment of the present invention. Figures 1 to 2 As shown, the device includes a housing 1 for a fertilizer screening machine, a fertilizer screening component 2 installed on the housing 1, and support legs 3 fixedly installed at each of the four ends of the housing 1. The above structure constitutes a fertilizer screening device.
[0020] refer to Figures 1 to 2 As shown, the screening assembly 2 includes two supports 11, a drive motor 12, and a rotating shaft 13. The supports 11 are fixedly installed on both sides of the housing 1. A circular frame 14 is fixedly connected to the rotating shaft 13. A cylindrical screen 15 for fertilizer is fixedly installed on the outside of the circular frame 14. A bearing seat 16 is rotatably installed on both sides of the rotating shaft 13. The bearing seat 16 is fixedly installed on one of the supports 11. The drive motor 12 is fixedly installed on the support 11. The output shaft of the drive motor 12 is connected to the rotating shaft 13. In this structure, the drive motor 12 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the cylindrical screen 15 to rotate through the circular frame 14. The cylindrical screen 15 is used to screen the fertilizer.
[0021] refer to Figures 1 to 2 As shown, the cylindrical screen 15 is provided with different apertures, and the cylindrical screen 15 is divided into several segments according to the aperture. The cylindrical screen 15 with different aperture segments can perform multi-stage screening of the material.
[0022] refer to Figures 1 to 2 As shown, both the casing 1 and the screening component 2 are inclined. The inclined design facilitates the natural rolling of the screened fertilizer as it rotates, thereby achieving continuous conveying and screening.
[0023] refer to Figures 1 to 2 As shown, a discharge port 10 is provided at the bottom of the casing 1, and a tray 4 is provided at the lower part of the casing 1. Multiple discharge hoppers 5 are fixedly connected to the tray 4. In this structure, the fertilizer screened out will fall from the discharge port 10 into the discharge hopper 5 on the corresponding tray 4 for discharge and collection.
[0024] refer to Figures 1 to 2 As shown, each of the support legs 3 is fixedly connected to a support 6, and a spring 7 is connected between the support 6 and the pallet 4. A vibration motor 8 is fixedly installed on the discharge hopper 5. When discharging material, the vibration motor 8, in conjunction with the spring 7, drives the discharge hopper 5 and the pallet 4 to vibrate. The vibration force reduces the possibility of fertilizer with high water content adhering to the discharge hopper 5, thereby achieving fast and stable material discharge.
[0025] refer to Figures 1 to 2 As shown, a telescopic cloth cover 9 is provided around the connection between the pallet 4 and the housing 1. This structure uses the telescopic cloth cover 9 to prevent fertilizer from leaking out between the pallet 4 and the housing 1. At the same time, the telescopic design allows vibration to pass through the space.
[0026] refer to Figures 1 to 2 As shown, a return hopper 17 is fixedly connected to one side of the pallet 4. In this structure, the return hopper 17 can be used to recover the large volume fertilizer that has been screened, thus facilitating its later recycling and reprocessing.
[0027] The implementation principle of a fertilizer screening device according to an embodiment of this application is as follows: In use, the drive motor 12 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the cylindrical screen 15 to rotate through the circular frame 14. The cylindrical screen 15 is used to screen the fertilizer. The screened and graded fertilizer will fall from the discharge port 10 into the discharge hopper 5 on the corresponding tray 4 for discharge and collection. When discharging, the vibration motor 8 and the spring 7 are used to drive the discharge hopper 5 and the tray 4 to vibrate. The vibration force reduces the possibility of fertilizer with high water content adhering to the inner wall of the discharge hopper 5, thereby achieving fast and stable discharge.
