Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fertilizer raw material metering, in particular to a raw material metering device for fertilizer production. Background Art
[0002] Fertilizer raw material metering devices, as key equipment in the fertilizer production, processing, and distribution processes, are designed to accurately measure and distribute fertilizer raw materials. Their core function is to ensure the accuracy of fertilizer raw material metering, thereby optimizing production efficiency, reducing unnecessary waste, and ensuring the quality of the final product.
[0003] However, in practical applications, fertilizer raw material metering devices can face challenges. Because fertilizer particles are not tightly packed together but rather have gaps between them, this can lead to deviations between the actual measured volume or weight and the theoretical value. This deviation is particularly significant when the raw material has poor flowability.
[0004] Furthermore, changes in humidity during storage and use of fertilizer raw materials can affect their volume, further impacting metering accuracy. Over long periods of operation, key components of metering devices, such as the hopper and sensors, can wear out, directly impacting metering accuracy. Utility Model Content
[0005] The main purpose of the utility model is to provide a raw material metering device for fertilizer production, which can effectively solve the problems raised in the background technology.

The silo wall vibrator drives the primary screening net to vibrate to perform preliminary screening of the fertilizer raw materials.
[0008] A screening through hole is formed in the buffer connecting cylinder, and a second screening net is connected to the hole wall of the screening through hole. The silo wall vibrator drives the buffer connecting cylinder and the second screening net to vibrate to further screen the fertilizer raw materials. The screened fertilizer is filled into the measuring bucket to reduce the gap between the fertilizers in the measuring bucket.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example
[0024] When discussing in detail a raw material metering device for fertilizer production, we must first focus on its structural composition. Figures 1 to 4 As shown, the device primarily consists of a metering hopper 10, a vibrating drum 1, and a buffer connection drum 6. The metering hopper 10, serving as the core metering container, is tightly connected to the vibrating drum 1 at its upper end via a specially designed buffer connection drum 6. A feed hopper 2 is located at the top of the vibrating drum 1. A primary screening net 3 is cleverly installed at the junction of the feed hopper 2 and the vibrating drum 1. This design allows the vibration of the silo wall vibrator 4 to drive the primary screening net 3 for preliminary screening of the fertilizer raw materials.
[0025] The buffer connecting cylinder 6 is internally designed with a screening hole 9, with a secondary screening mesh 8 mounted on its wall. When the silo wall vibrator 4 is activated, it not only vibrates the primary screening mesh 3, but also the buffer connecting cylinder 6 and the secondary screening mesh 8, thereby further screening the fertilizer raw materials. After this series of screening processes, the selected fertilizer raw materials ultimately fall into the measuring hopper 10, effectively reducing the gaps between the fertilizer raw materials within the measuring hopper 10.
[0026] The vibrating drum 1 and the feed hopper 2 are integrated into a trumpet-shaped design, which is not only aesthetically pleasing but also effectively improves screening efficiency in practical use. The primary screening net 3 is bolted to the vibrating drum 1, ensuring its stability and reliability.
[0027] The mesh diameter of the primary screening net 3 is larger than that of the secondary screening net 8. This design ensures that the fertilizer material particles are more uniform in size after two screenings. The secondary screening net 8 is fixed to the inner wall of the buffer connecting cylinder 6 by winding steel wire and adopts a frustum-shaped design, which makes the screening process smoother.
[0028] The side wall of the buffer connection tube 6 is provided with an annular groove 7, which is made of a rubber cylinder to ensure a sealed connection with the vibration tube 1 and the metering hopper 10. The buffer connection tube 6 is fixed to the vibration tube 1 and the metering hopper 10 by bolts, making the entire device more stable. Example
[0029] Based on the first embodiment, we have made some improvements to the raw material metering device for fertilizer production. First, the metering hopper 10 is designed as a transparent metering cylinder, so that the user can clearly see the fertilizer raw material inside the metering hopper 10. Furthermore, the metering hopper 10 is a quantitative metering cylinder with a metering scale engraved on it, which facilitates the user to accurately measure.
[0030] Secondly, the silo wall vibrator 4 is mounted on the vibrating cylinder 1 via a connector 5. A rubber gasket is provided at the connection between the connector 5 and the vibrating cylinder 1. This design effectively reduces noise and vibration transmission during the vibration process. The connector 5 and the vibrating cylinder 1 are welded together to ensure a secure and stable connection.
[0031] The raw material metering device for fertilizer production further improves the convenience and accuracy of use while maintaining the original advantages.
[0032] During operation: The measuring hopper 10 is the core measuring container, and its upper end is connected to the vibrating drum 1 through a specially designed buffer connection tube 6. A feed hopper 2 is installed on the top of the vibrating drum 1. The first screening net 3 is installed at the connection with the vibrating drum 1. The fertilizer raw materials are initially screened through the vibration of the silo wall vibrator 4.
[0033] The buffer connection tube 6 has a screening hole 9 inside, with a secondary screening screen 8 installed on the wall. This screen works in conjunction with the silo wall vibrator 4 to further screen the fertilizer raw materials. The screened fertilizer raw materials fall into the measuring hopper 10, effectively reducing the gaps between the fertilizer raw materials in the measuring hopper 10.
[0034] The vibrating drum 1 and feed hopper 2 are integrated into a trumpet-shaped design, enhancing screening efficiency. The primary screening net 3 has a larger mesh diameter than the secondary screening net 8, ensuring a more uniform particle size of the fertilizer raw materials. The secondary screening net 8 features a frustum-shaped design, facilitating a smoother screening process.
[0035] The side wall of the buffer connection tube 6 is provided with an annular groove 7, which is made of a rubber cylinder to ensure a sealed connection with the vibration tube 1 and the metering hopper 10. The buffer connection tube 6 is fixed by bolts to make the device more stable.
[0036] The further improved measuring bucket 10 is designed as a transparent measuring cylinder, and the user can clearly see the fertilizer raw material situation in the measuring bucket 10. The measuring bucket 10 is a quantitative measuring cylinder with a measuring scale engraved on it, which is convenient for the user to carry out accurate measurement.
[0037] The silo wall vibrator 4 is mounted on the vibrating cylinder 1 via a connector 5. A rubber gasket is installed at the connection between the connector 5 and the vibrating cylinder 1 to reduce noise and vibration transmission during the vibration process. The connector 5 and the vibrating cylinder 1 are welded together to ensure a firm and stable connection.
