Description

Technical Field

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

[0002] In the compound fertilizer production process, the mixing effect of the mixing device plays a crucial role in product quality. Currently, the common mixing method is to use a stirring device for mixing. However, in actual operation, this method has certain defects. During mixing, some materials tend to accumulate at the bottom of the device due to their own weight, particle characteristics, etc. The bottom material is difficult to fully contact with other materials, resulting in it not being evenly dispersed in the overall material. This leads to deviations in the composition ratio of the compound fertilizer. This not only affects the balance of nutrients in the compound fertilizer and reduces the fertilizer utilization rate, but may also have an adverse effect on crop growth, failing to meet the agricultural production demand for high-quality compound fertilizer.

[0003] To address the problem of uneven mixing caused by material accumulation, improve the balance and utilization rate of fertilizer nutrients, ensure the healthy growth of crops, and meet the stringent requirements of agricultural production for high-quality compound fertilizers, we propose a mixing device for compound fertilizer production.

[0016] In use, materials are fed into the feed port 2. The driving component drives the stirring mechanism to initially stir the falling materials. The stirred materials fall to the bottom of the cylinder 6 and enter the sleeve 21 through the feed port 20. The driving component drives the rotating rod 17 to rotate, which in turn drives the auger blades 18 to rotate, transporting the materials from the feed port 20 to the discharge port 22. The materials are then output from the discharge port 22. Subsequently, the stirring mechanism stirs the materials again, thus achieving uniform mixing. This solves the problem of uneven mixing caused by material accumulation, improves the balance and utilization rate of fertilizer nutrients, ensures the healthy growth of crops, and meets the stringent requirements of agricultural production for high-quality compound fertilizers.

[0017] The discharge mechanism includes several sets of electric push rods 25. The electric push rods 25 are fixedly installed on the top of the cylinder 6. The output end of the electric push rod 25 is fixedly connected to a fixed plate 5. The fixed plate 5 is rotatably sleeved on the outside of the rotating rod 17. The bottom end of the rotating rod 17 is fixedly connected to a baffle 19. The baffle 19 is movably connected to the inner wall of the sleeve 21.

[0018] After mixing, the electric push rod 25 drives the fixed plate 5 to move upward, which in turn drives the motor 4, rotating rod 17, auger blade 18 and baffle 19 to move upward until the baffle 19 moves above the feed inlet 20, so that the material is discharged from the feed inlet 20.

[0019] The stirring mechanism includes a mounting plate 9, which is rotatably connected to the inner wall of the cylinder 6. The mounting plate 9 is rotatably sleeved on the outside of the sleeve 21. Several sets of fixing rods 10 are fixedly installed at the bottom of the mounting plate 9. Several sets of first stirring paddles 11 are fixedly installed on the side of the fixing rods 10 near the sleeve 21. Several sets of second stirring paddles 12 are fixedly installed on the outside of the sleeve 21.

[0020] The drive assembly drives the mounting plate 9 to rotate, which in turn drives the fixed rod 10 and the first stirring paddle 11 to rotate. At the same time, the drive assembly also drives the sleeve 21 to rotate, which in turn drives the second stirring paddle 12 to rotate, thus stirring the material.

[0021] The drive assembly includes a motor 4, which is fixedly mounted on the top of the fixed plate 5. The output end of the motor 4 is fixedly connected to the top of the rotating rod 17. The top of the cylinder 6 is rotatably connected to an installation tube 23, which is slidably sleeved on the outside of the rotating rod 17. A second pulley 16 is fixedly sleeved on the outside of the installation tube 23. A connecting rod 14 is rotatably passed through the cylinder 6. A first pulley 15 is fixedly connected to the top of the connecting rod 14. A belt is tensioned between the second pulley 16 and the first pulley 15. A second gear 13 is fixedly connected to the end of the connecting rod 14 away from the first pulley 15. A first gear 8 is fixedly sleeved on the outside of the sleeve 21. The first gear 8 meshes with the second gear 13. A gear ring 7 is fixedly mounted on the top of the mounting plate 9. The gear ring 7 meshes with the second gear 13.

[0022] The motor 4 drives the rotating rod 17 to rotate in the forward direction, which in turn drives the mounting tube 23 and the second pulley 16 to rotate in the forward direction, which in turn drives the first pulley 15, the connecting rod 14, the second gear 13 and the gear ring 7 to rotate in the forward direction, which in turn drives the mounting plate 9 to rotate. The rotation of the second gear 13 drives the first gear 8 to rotate in the reverse direction, which in turn drives the sleeve 21 to rotate in the reverse direction.

[0023] The fixing rod 10 abuts against the inner wall of the cylinder 6 on the side closest to the cylinder 6. This allows for the cleaning of materials adhering to the inner wall of the cylinder 6.

[0024] A protective cover 24 is fixedly installed on the top of the cylinder 6, and the protective cover 24 is movably sleeved on the outside of the rotating rod 17. It can serve a protective function.

[0025] Working principle: During use, material is fed into the feeding port 2. The motor 4 drives the rotating rod 17 to rotate forward, which in turn drives the mounting tube 23 and the second pulley 16 to rotate forward. This, in turn, drives the first pulley 15, connecting rod 14, second gear 13, and gear ring 7 to rotate forward, causing the mounting plate 9 to rotate. This, in turn, drives the fixed rod 10 and the first stirring paddle 11 to rotate. Simultaneously, the rotation of the second gear 13 drives the first gear 8 to rotate in the opposite direction, causing the sleeve 21 to rotate in the opposite direction, which in turn drives the second stirring paddle 12 to rotate. The reverse rotation of the first stirring paddle 11 and the second... The stirring paddle 12 initially agitates the falling material. The agitated material falls to the bottom of the cylinder 6 and enters the sleeve 21 through the feed inlet 20. The rotating rod 17 rotates, driving the auger blades 18 to rotate, transporting the material from the feed inlet 20 to the discharge outlet 22. The material is then discharged from the discharge outlet 22. Subsequently, the stirring mechanism agitates the material again, thus achieving uniform mixing. This solves the problem of uneven mixing caused by material accumulation, improves the balance and utilization rate of fertilizer nutrients, ensures the healthy growth of crops, and meets the stringent requirements of agricultural production for high-quality compound fertilizers. After mixing is complete, the electric push rod 25 drives the fixed plate 5 to move upward, which in turn drives the motor 4, rotating rod 17, auger blades 18, and baffle 19 to move upward until the baffle 19 moves above the feed inlet 20, allowing the material to be discharged from the feed inlet 20.
