Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figure 1 - Figure 7 An embodiment of this utility model is provided: an organic fertilizer slow-release coating machine, including a workbench 8, a support 9 fixedly connected to the top of the workbench 8, a powder conveying mechanism provided on the top of the support 9, a base 6 fixedly connected to the top of the workbench 8, multiple baffles 7 fixedly connected to the top of the base 6, an anti-blocking mechanism provided on the top of the base 6, two fixed frames 3 fixedly connected to the outside of the baffles 7 and symmetrically distributed, a mixing tank 2 fixedly connected between the two fixed frames 3, and a mixing mechanism provided inside the mixing tank 2;
[0036] The anti-blocking mechanism includes a discharge hopper 4 and a drive unit 18. A turntable 17 is fixedly connected to the output end of the drive unit 18. An annular groove 21 is formed on the top of the turntable 17, and multiple protrusions 20 are fixedly connected inside the annular groove 21. Multiple support columns 19 are fixedly connected to the top of the base 6. The bottom of the turntable 17 is slidably connected to the top of the support columns 19. Multiple connecting columns 16 are fixedly connected to the bottom of the discharge hopper 4, and sliding wheels 23 are fixedly connected to the bottom of the connecting columns 16. A limit plate 22 is fixedly connected to the inner side of the baffle 7, and the connecting columns 16 are slidably connected inside the limit plate 22. An electric lifting door 15 is installed inside the discharge hopper 4. The protrusions 20 abut against the sliding wheels 23, and the discharge hopper 4 is slidably connected to the inner side of the baffle 7. The workbench 8 is the basic support for the entire equipment, bearing all other parts and providing a stable working platform. The bracket 9 is used to support and fix the powder conveying mechanism, ensuring the stability of the powder conveying mechanism's position. The base 6 is used to support the baffle 7, providing a working foundation for the anti-blocking mechanism. Multiple baffles 7 are evenly distributed on the top of the base 6, forming a semi-enclosed space to protect the internal components and to secure the external mounting bracket 3. The mounting bracket 3 secures the mixing tank 2, providing a foundation for its stable operation. The mixing tank 2 contains and mixes fertilizer and coating liquid materials, ensuring uniform mixing. The discharge hopper 4 holds the fertilizer fully mixed with the coating liquid materials and provides a workspace for the next step of powdering. The drive unit 18 drives the turntable 17 to rotate, providing power for the anti-clogging mechanism. The turntable 17 rotates its internal protrusions 20, cooperating with the sliding wheel 23 to move the sliding wheel 23 up and down on the protrusions 20, thereby causing the discharge hopper 4 connected to the connecting column 16 to vibrate up and down, and also to ensure more uniform powdering of the fertilizer. The support column 19 supports the turntable 17, allowing it to rotate stably. The limiting plate 22 restricts the connecting column 16 to move only up and down, ensuring stable vibration of the discharge hopper 4. The electric lifting door 15 releases the fertilizer after it has been powdered and allows it to flow into the collection box 5. The annular groove 21 allows the sliding wheel 23 to slide smoothly on the turntable 17.
[0037] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7The stirring mechanism includes a motor 1, which is mounted on the top of the mixing tank 2. A square rod 29 is fixedly connected to the output end of the motor 1. A sliding sleeve 30 is slidably connected to the outside of the square rod 29. An eccentric disk 31 is fixedly connected to the outside of the sliding sleeve 30. Multiple stirring rods 28 are slidably connected to the outside of the sliding sleeve 30. An anti-stick component is provided at the end of the stirring rod 28 away from the sliding sleeve 30. A fixed rod 33 is fixedly connected to the top of the mixing tank 2. An upper roller 34 and a lower roller 32 are fixedly connected to the fixed rod 33 from top to bottom. The eccentric disk 31 is slidably connected between the upper roller 34 and the lower roller 32. The motor 1 drives the square rod 29 to rotate, thereby causing the sliding sleeve 30 to rotate. While the sliding sleeve 30 rotates, the eccentric disk 31, under the action of the upper roller 34 and the lower roller 32, drives the sliding sleeve 30 to move up and down by relying on the cooperation between the square hole inside the sliding sleeve 30 and the square rod 29, thereby realizing up-and-down stirring. Through this process, the stirring effect is evenly achieved. The fixing rod 33 is used to fix the upper roller 34 and the lower roller 32. The stirring rod 28 is used to fully mix the fertilizer with the coated liquid material.
[0038] Reference Figure 1 , Figure 2 and Figure 5 The powder conveying mechanism includes a second motor 10 and a discharge bucket 12. Both the second motor 10 and the discharge bucket 12 are fixedly connected to the top of the support 9. An auger 14 is fixedly connected to the output end of the second motor 10. The auger 14 is rotatably connected inside the discharge bucket 12. The end of the discharge bucket 12 furthest from the second motor 10 is located above the discharge hopper 4. A sliding wheel 23 is slidably connected inside the annular groove 21. A second feed pipe 13 is fixedly connected to the top of the mixing tank 2. A first feed pipe 11 is installed on the top of the discharge bucket 12. A collection box 5 is installed on the top of the workbench 8. The second motor 10 provides power to drive the auger 14 to rotate, thereby promoting the conveying of powder. The discharge bucket 12 stores and conveys powder, ensuring that the powder is smoothly delivered to the discharge hopper 4. The auger 14 is connected to the output end of the second motor 10. After rotation, it drives the powder to move within the discharge bucket 12, ensuring smooth discharge of the material. The support 9 supports and fixes the second motor 10 and the discharge bucket 12, ensuring the stability of the equipment. Feed pipe 2 13 is connected to mixing tank 2 and is used to input fertilizer and coating liquid materials into mixing tank 2 for thorough mixing. Feed pipe 1 11 is installed on top of discharge hopper 12 and is used to input powder materials, providing a material source for discharge hopper 12.
[0039] Reference Figure 5 , Figure 6 and Figure 7The anti-sticking component includes a hollow box 25, which is fixedly connected to the end of the stirring rod 28 away from the sliding sleeve 30. Multiple springs 27 are installed inside the hollow box 25. A limiting strip 26 is slidably connected inside the hollow box 25. A scraper 24 is fixedly connected to one side of the limiting strip 26. One end of the scraper 24 passes through the hollow box 25 and is slidably connected inside the hollow box 25. The side of the scraper 24 away from the limiting strip 26 abuts against the inner wall of the mixing tank 2. The stirring rod 28 is rotatably connected inside the mixing tank 2. One end of each spring 27 is fixedly connected to the side of the limiting strip 26 away from the scraper 24, and the other end of the spring 27 abuts against the inner wall of the hollow box 25. The hollow box 25 serves to support all the internal connections, ensuring the normal operation of each component. The springs 27 allow for fine-tuning of the scraper 24 when it scrapes against the inner wall of the mixing tank 2, ensuring that the scraper 24 always abuts against the inner wall of the mixing tank 2. The limiting strip 26 is used to prevent the scraper 24 from sliding out of the hollow box 25.
[0040] Working Principle: During operation, fertilizer and coating liquid are first poured into mixing tank 2 through feed pipe 13. Then, motor 1 is started, driving the square rod 29 to rotate. The sliding sleeve 30, which is fitted onto the square rod 29, also rotates accordingly. Simultaneously, the eccentric disc 31 on the sliding sleeve 30, under the action of the upper roller 34 and lower roller 32, drives the sliding sleeve 30 to slide up and down on the square rod 29, thus achieving vertical mixing. The stirring rod 28 on the outside of the sliding sleeve 30 is responsible for mixing the fertilizer and coating liquid, ensuring thorough mixing. During mixing, scraper 24 scrapes away material from the inner wall of mixing tank 2, preventing it from adhering to the tank wall. With the help of spring 27, scraper 24 can slide and be finely adjusted within the hollow box 25, thus avoiding hard contact between scraper 24 and the inner wall of mixing tank 2, preventing damage to mixing tank 2.
[0041] After mixing is complete, the discharge port at the bottom of mixing tank 2 will automatically open, and the fertilizer will fall into discharge hopper 4. At this time, drive component 18 starts working, driving turntable 17 to rotate smoothly on support column 19. During the rotation of turntable 17, connecting column 16 moves up and down on protrusion 20 via sliding wheel 23, causing discharge hopper 4 to vibrate up and down. At the same time, motor 10 starts, driving auger 14 to rotate, sending powder through feed pipe 11 into discharge bucket 12, and under the action of auger 14, the powder is conveyed to discharge hopper 4. The vibration of discharge hopper 4 helps the powder and fertilizer to mix thoroughly. Finally, electric lifting door 15 opens, and the mixed fertilizer finally falls into collection box 5.
[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.
