Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically a mixing device for liquid fertilizer production. Background Technology

[0002] Liquid fertilizers have the advantages of being easily absorbed by crops and having a relatively high absorption and utilization rate. They can also be used in conjunction with drip irrigation equipment to achieve integrated water and fertilizer management. In the rapid development of modern agriculture, liquid fertilizers have become an indispensable and efficient fertilizer for modern agricultural production.

[0003] A search revealed a currently published patent: CN220589677U, which discloses a liquid fertilizer production device, including a mixing tank and a belt. A machine housing is fixedly connected to the top of the mixing tank, and a motor is fixedly connected to the top of the machine housing's inner cavity. A transmission rod is fixedly connected to the output shaft of the motor, and a drive pulley is fitted onto the surface of the transmission rod. This invention constructs a liquid fertilizer production device by setting up a mixing tank, belt, machine housing, motor, transmission rod, drive pulley, feed pipe, threaded feed rod, driven pulley, and storage pipe. The motor drives the transmission rod and stirring rod to rotate, enabling the mixing of solid materials and liquids.

[0004] However, the following situation may occur during the use of this device: Since the device injects fertilizer directly into the mixing tank through the feed pipe and then stirs the fertilizer with the stirring rod, the fertilizer cannot be evenly dispersed after being injected into the mixing tank. Stirring it with the stirring rod alone cannot guarantee that the fertilizer will be mixed more evenly. The fertilizer is prone to condensation and accumulation, which will affect the effect of the fertilizer mixture. In order to address the above situation, technical innovation will be carried out on the basis of the existing device. Utility Model Content

Detailed Implementation

[0019] Please see Figure 1-6This utility model provides a technical solution: a mixing device for liquid fertilizer production, including a mixing tank 1, a machine box 2 fixedly connected to the top of the mixing tank 1, and a feed inlet 3 for feeding the top of the machine box 2. The feed inlet is an existing structure and will not be described in detail. For details, please refer to the published patent: CN220589677U. A first motor 4 is fixedly connected to the upper surface inside the machine box 2. A power supply, wires, controller and microcomputer structure are provided in accordance with the first motor 4. Since the first motor 4 is not the main content, it will not be described in detail. A first rotating rod 5 is fixedly connected to the output end of the first motor 4. The first rotating rod 5 rotates through the machine box 2 and extends into the interior of the mixing tank 1. A power block 6 is fixedly connected to the upper surface inside the mixing tank 1. The surface of the power block 6 is provided with a curved surface for transmission. The interior of the power block 6 is slidably connected to the surface of the first rotating rod 5. A limit groove 16 is opened at the bottom of the first rotating rod 5. A power adjustment device is provided inside the limit groove 16.

[0020] Please refer to Figure 5 The power adjustment device includes a limiting block 18, which is internally slidably connected to the limiting groove 16. A second rotating rod 7 is fixedly connected to the bottom of the limiting block 18. Two symmetrical transmission rods 9 are fixedly connected to the surface of the second rotating rod 7. The cross-section of the transmission rod 9 is L-shaped. A rotating column 10 is rotatably connected to one side of the top of the transmission rod 9. The rotating column 10 is located above the curved surface of the power block 6.

[0021] Please refer to Figure 4 The surface of the second rotating rod 7 is fixedly connected to a disc 8 for bearing fertilizer and spreading it evenly. The surface of the disc 8 is provided with multiple holes to facilitate the leakage of waste. The surface of the second rotating rod 7 is provided with multiple agitator rods for stirring.

[0022] Please refer to Figure 5 The top of the limiting block 18 is fixedly connected to the spring 17, and the top of the spring 17 is fixedly connected to the inner wall of the limiting groove 16. By making the limiting block 18 slide up and down, the spring 17 can be compressed and reset.

[0023] The worker injects the fertilizer to be mixed into the mixing box 1 through the feed inlet 3. The fertilizer falls onto the disc 8. Then, the worker starts the first motor 4 through the controller and microcomputer structure. The output end of the first motor 4 drives the first rotating rod 5 to rotate. The first rotating rod 5 drives the second rotating rod 7 to rotate through the limit block 18. The second rotating rod 7 drives the disc 8 to rotate, so that the fertilizer falls evenly onto the disc 8 and drives the transmission rod 9 to rotate. The transmission rod 9 drives the rotating column 10 to rotate. The surface of the rotating column 10 contacts the curved surface on the power block 6, causing the spring 17 to be continuously compressed and reset, and causing the second rotating rod 10 to rotate. The rotating rod 7 vibrates up and down under force, causing the disc 8 to vibrate up and down as well. This allows the fertilizer to fall evenly into the mixing tank 1 through the holes. The disturbance rods on the surface of the second rotating rod 7 can stir the fertilizer. The second rotating rod 7 drives the disc 8 and the disturbance rods to rotate synchronously and vibrate up and down, resulting in efficient mixing of the liquid fertilizer during the stirring process. The holes on the disc ensure even distribution of the liquid, while the disturbance rods enhance the fluidity and mixing effect of the liquid, thereby improving the uniformity of the fertilizer, effectively reducing sedimentation and clumping, ensuring the stability of the fertilizer components, and improving the fertilization effect.

[0024] Please refer to Figure 2 A bracket 21 is fixedly connected to the bottom of the mixing box 1. The bracket 21 has an L-shaped cross section. A second motor 22 is fixedly connected to the top of the bracket 21. The second motor 22 has the same configuration as the first motor 4. A connecting rod 12 is fixedly connected to the output end of the second motor. The connecting rod 12 rotates through the mixing box 1 and extends into its interior. A crossbar 13 is fixedly connected to the bottom of the connecting rod 12. Both ends of the crossbar 13 are fixedly connected to scrapers 14 for cleaning. The scraper 14 has an inclined surface on the side near the inner wall of the mixing box 1.

[0025] Please refer to Figure 6 A sliding groove 19 is provided on one side of the scraper 14. A sliding block 15 extending to the outside of the sliding groove 19 is slidably connected inside the sliding groove 19. The cross-section of the sliding block 15 is T-shaped. A brush 11 is fixedly connected to the end of the sliding block 15 away from the sliding groove 19. The brush 11 is located above the disc 8. The brush 11 can disturb the fertilizer above the disc. A tension spring 20 is fixedly connected to the bottom of the sliding block 15. The bottom of the tension spring 20 is fixedly connected to the inner wall of the sliding groove 19. By sliding the sliding block 15 up and down, the tension spring 20 can be stretched and reset.

[0026] The operator starts the second motor 22 via the controller and microcomputer structure. The output end of the second motor 22 rotates in reverse, driving the connecting rod 12 to rotate. The connecting rod 12 drives the crossbar 13 to rotate, and the crossbar 13 drives the scraper 14 to rotate. The scraper 14 can scrape and clean the inner wall of the mixing chamber 1. Cleaning the inner wall of the mixing chamber 1 with the scraper 14 can effectively reduce the adhesion of fertilizer liquid or viscous substances to the inner wall, reduce residue accumulation, and maintain the cleanliness of the mixing chamber. This ensures that the fertilizer composition is uniform each time it is mixed, reduces the frequency and difficulty of manual cleaning, lowers maintenance costs, reduces fertilizer waste caused by residual pollution, and improves raw material utilization.

[0027] The scraper 14 is rotated, and the scraper 14 drives the brush 11 to rotate through the sliding block 15. The top of the disk 8 contacts one side of the sliding block 15, and the disk shakes up and down, which causes the sliding block 15 to shake up and down under force, and the tension spring 20 to be stretched and reset continuously. This keeps the position of the brush and the disk 8 consistent, and allows the brush 11 to agitate the fertilizer on the disk 8. By agitating the fertilizer on the top of the disk with the brush 11, the accumulation of fertilizer on the top of the disk can be effectively reduced, ensuring that the fertilizer is evenly distributed, thereby improving the mixing effect and application uniformity. Secondly, the physical agitation of the brush can reduce the accumulation of fertilizer particles at the drain hole, reduce the risk of blockage, ensure that the fertilizer passes through the drain hole smoothly, and improve the working efficiency of the equipment.

[0028] Overall, the brush's agitation function on the top of the disc not only prevents fertilizer buildup and clogging, but also optimizes the mixing and fertilization process, reduces maintenance costs, and improves the stability and lifespan of the equipment, making it more suitable for the preparation and application of liquid fertilizers in agricultural production.

[0029] Working principle: For this type of liquid fertilizer production mixing device, the operator first starts the first motor 4 and the second motor 22 through the controller and microcomputer structure. The output ends of the first motor and the second motor rotate in opposite directions. The output end of the first motor 4 drives the first rotating rod 5 to rotate, the first rotating rod 5 drives the second rotating rod 7 to rotate, the second rotating rod 7 drives the transmission rod 9 and the disc 8 to rotate, the transmission rod 9 drives the rotating column 10 to rotate, and makes the second rotating rod 7 and the disc 8 vibrate up and down. At the same time, the disturbance rod disturbs the fertilizer inside the mixing box 1. The output end of the second motor 22 drives the connecting rod 12 to rotate, the connecting rod 12 drives the crossbar 13 to rotate, the crossbar 13 drives the scraper 14 to rotate, the scraper 14 scrapes and cleans the inner wall of the mixing box 1, and the scraper 14 drives the brush to disturb the fertilizer on the top of the disc 8.
