[0001] This utility model relates to the field of fertilizer screening technology, and in particular to a fertilizer granule screening device. Background Technology

[0002] During the application of fertilizers, different particle sizes are suitable for different fertilization environments. The larger the particle size, the slower the fertilizer dissolves and the longer its fertility lasts. Therefore, fertilizers usually need to be screened after production.

[0003] Currently, most fertilizer screening methods use vibrating screens to separate fertilizer granules. However, fertilizer granules have low hardness and abrasion resistance, and vibrating screens will crush a large number of granules, damaging their integrity and producing a lot of fertilizer residue, resulting in waste. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fertilizer granule screening device, which aims to solve the problem that vibrating screening will crush a large number of fertilizer granules, destroy the integrity of the fertilizer granules, and result in a lot of fertilizer granule residue, causing waste.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0023] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a fertilizer granule screening device, including a device housing 1, a feed hopper 2 on the upper side of the device housing 1, a conveyor belt 8 below the feed hopper 2, the conveyor belt 8 being located inside the device housing 1, a comb-type distributor 7 on the upper side of the conveyor belt 8, a blower 9 below the conveyor belt 8, a screen plate 11 below the end of the conveyor belt 8 away from the feed hopper 2, a discharge port 13 inside the screen plate 11, and a storage box 4 below the screen plate 11, the storage box 4 being located on the inner bottom wall of the device housing 1.

[0024] In this embodiment, Figure 1 The orientation is indicated by front, back, left, and right. The comb-type distributor 7 consists of multiple parallel comb teeth. The spacing between the comb teeth is designed according to the average particle size of the fertilizer granules, slightly larger than the particle size. When the fertilizer granules are conveyed to the end by the conveyor belt, the comb-type distributor 7 combs the accumulated granules into a uniform line, maintaining a relatively uniform interval between each particle, which is existing technology. The blower 9 can output stable and adjustable air force, and a centrifugal blower can be selected, which is existing technology.

[0025] When using this device, the housing 1 provides support for the device. Fertilizer granules are poured into the feed hopper 2. Through the action of the feed hopper 2, the fertilizer granules are arranged on the conveyor belt 8. Driven by the conveyor belt 8, the fertilizer granules are conveyed to the left. Under the interference of the comb-type distributor 7, the fertilizer granules on the conveyor belt 8 are evenly spread on the left end of the conveyor belt 8. Then, the fertilizer granules fall from the conveyor belt 8. Driven by the blower 9, the fertilizer granules are blown. Under the combined action of the same wind force and gravity, fertilizer granules of different weights are horizontally offset to different degrees according to the expected trajectory and then fall into the screen plate 11. They fall into different storage boxes 4 through the discharge port 13 on the screen plate 11. This realizes the screening of fertilizer granules without the use of vibrating screen, thus solving the problem that vibrating screen will crush a large number of fertilizer granules, destroy the integrity of the fertilizer granules, and cause a lot of fertilizer granule residue, resulting in waste.

[0026] Reference Figure 1 and Figure 2The inside of the feed hopper 2 is rotatably connected to a paddle 3, and a motor 15 is provided on one side of the feed hopper 2. The output end of the motor 15 is fixedly mounted on the paddle 3.

[0027] Specifically, fertilizer granules are introduced into the feed hopper 2, which supports the motor 15. The motor 15 drives the blades 3 and the feed hopper 2 to rotate, thereby breaking up the lumpy fertilizer granules in the feed hopper 2, which is beneficial for the subsequent screening of fertilizer granules.

[0028] Reference Figure 2 The air outlet of the fan 9 is equipped with an air guide nozzle 10, which is located on the upper right side of the sieve plate 11.

[0029] Specifically, the air guide nozzle 10 is used to homogenize and guide the air force provided by the fan 9 horizontally. The position design of the air guide nozzle 10 allows the air force of the fan 9 to be blown towards the fertilizer granules falling above the screen plate 11, thereby improving the utilization efficiency of the air force.

[0030] Reference Figure 1 and Figure 2 A vent 6 is provided on one side of the device housing 1. The vent 6 and the air guide nozzle 10 are located at the same horizontal height, and the air outlet of the air guide nozzle 10 faces the vent 6.

[0031] Specifically, by setting up the vent 6, the air force through the air guide nozzle 10 can be blown directly out of the vent 6 after acting on the fertilizer particles, avoiding the inner wall of the device housing 1 from blocking the air force and forming a complex air circulation path, which would affect the screening of fertilizer particles.

[0032] Reference Figure 1 and Figure 4 A filter screen 18 is provided on one side of the device housing 1, and the filter screen 18 is located inside the vent 6.

[0033] Specifically, the filter 18 prevents external foreign objects from entering the device housing 1 through the vent 6, thus preventing contamination of the fertilizer particles; at the same time, it also prevents lighter fertilizer particles from being blown outside the device housing 1, thus avoiding waste.

[0034] Reference Figure 2 A material distribution rod 14 is fixedly connected to the inner wall of the sieve plate 11, and the material distribution rod 14 and the discharge port 13 are alternately distributed.

[0035] Specifically, the upper part of the dividing rod 14 is in the shape of a triangular cone. There are multiple dividing rods 14 and discharge ports 13. The dividing rods 14 guide the falling fertilizer particles to the discharge ports 13, thereby avoiding the accumulation of fertilizer particles on the screen plate 11.

[0036] Reference Figure 2 A baffle 12 is provided on the upper side of the screen plate 11, and the side of the baffle 12 away from the vent 6 is located below the air guide nozzle 10.

[0037] Specifically, some fertilizer particles fall onto the edge of the screen plate 11 and the distribution rod 14, and are then bounced up. The baffle frame 12 intercepts the fertilizer particles that bounce up in all directions and returns them to the discharge port 13, thus avoiding waste of fertilizer particles.

[0038] Reference Figure 2 and Figure 3 A storage box 17 is fixedly connected to the inner bottom wall of the device housing 1. The storage box 4 is located inside the storage box 17. A discharge pipe 16 is fixedly installed between the front and rear side walls of the storage box 17. The upper end of the discharge pipe 16 is located below the discharge port 13. The side wall of the storage box 4 passes through one side of the storage box 17. A handle 5 is fixedly connected to one side of the storage box 4.

[0039] Specifically, the housing 1 provides support for the storage box 17. Fertilizer granules of different sizes fall into different discharge ports 13, and then through the discharge pipe 16 below the discharge port 13, and through the fixed arrangement of the discharge pipe 16 and the storage box 17, they fall into different storage boxes 4, thereby completing the collection of fertilizer granules of different sizes. The storage box 4 can be pulled out through the handle 5, which helps to achieve the screening of fertilizer granules.

[0040] Working principle: When using this device, fertilizer granules are poured into the feed hopper 2. Driven by the output of motor 15, the paddle 3 is rotated to break up the lumpy fertilizer granules. Then, the fertilizer granules pass through the lower side of the feed hopper 2 and are arranged on the conveyor belt 8. Driven by the conveyor belt 8, the fertilizer granules are conveyed to the left. The interference of the comb-type distributor 7 on the fertilizer granules evenly spreads the fertilizer granules on the left end of the conveyor belt 8 and then falls off the conveyor belt 8, thus achieving the effect of uniformly arranging the fertilizer granules in a line.

[0041] Driven by the fan 9, the generated wind is guided by the air guide nozzle 10 to blow the falling fertilizer granules. Under the combined effect of the same wind force and gravity, fertilizer granules of different weights deviate horizontally to different degrees according to the expected trajectory and then fall into the screen plate 11. Fertilizer granules of different sizes pass through the feed port 13 and the discharge pipe 16 and fall into different storage boxes 4. This achieves the screening of fertilizer granules without the use of vibrating screen, thus solving the problem that vibrating screen will crush a large number of fertilizer granules, destroy the integrity of fertilizer granules, and cause a lot of fertilizer granule residue and waste.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
