[0002] In corn cultivation, the uniform mixing of fertilizers is a crucial step in ensuring effective fertilization, directly impacting crop yield and quality. Currently, mixers are commonly used in agricultural production for fertilizer mixing, but the following problems exist in practical application:

[0003] Traditional single-inlet gate design leads to a concentrated feeding area, making it easy for fertilizer to accumulate in dead corners within the mixing chamber. Moreover, most existing mixers have a straight-cylinder discharge design, which causes fertilizer to splash and spread due to gravity during discharge, resulting in material accumulation off-center. Workers need to repeatedly move the collection bucket to catch the material or manually rake it level, which increases labor intensity and easily causes dust pollution.

[0004] Therefore, a fertilizer mixing device that combines efficient mixing, low residue, stable support, and precise material collection is proposed to meet the operational needs of large-scale corn planting. Utility Model Content

[0005] The purpose of this utility model is to provide a fertilizer mixer for corn planting, which has the function of mixing fertilizer for corn planting. It solves the problems of the concentrated feeding area of ​​the existing technology, the easy accumulation of fertilizer in the mixing chamber, and the fact that the discharge of the existing mixers is mostly a straight cylinder design. When discharging, the fertilizer splashes and spreads due to gravity free fall, causing the material to accumulate off the center. Workers need to repeatedly move the collection bucket to receive the material or manually rake it, which increases the labor intensity and easily causes dust pollution.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, such as Figure 1-3 As shown, a fertilizer mixer for corn planting includes a mixing chamber 1, a supporting structure, a feeding mechanism, a mixing structure, and a discharging structure. The mixing chamber 1 is the core container for fertilizer mixing, containing materials and cooperating with the mixing structure to complete the mixing process. A supporting structure is provided at the bottom of the mixing chamber 1, comprising three pillars 2 evenly distributed around the circumference at 120° intervals. Each pillar 2 is connected to a support 3 at its bottom. The pillars 2 and supports 3 support the overall structure of the mixing chamber 1, maintaining its stability. The three pillars 2 arranged at 120° intervals form a triangular stable structure, and the expanded support 3 increases the ground contact area.

[0024] A collection bucket 4 is located at the center of the support 3. The collection bucket 4 receives the mixed fertilizer for easy transportation to the field. A feeding mechanism is located at the top of the mixing chamber 1. The feeding mechanism includes two symmetrically arranged feeding doors 5. Each feeding door 5 is equipped with a handle 6 and is connected to the top wall of the mixing chamber 1 via a pivot 7. The handle 6 facilitates the opening and closing of the feeding door 5. The symmetrical double feeding door 5 design enables zoned feeding. The pivot 7 hinge ensures smooth opening and closing, allowing fertilizer to be fed into different areas and eliminating dead zones caused by single-point accumulation.

[0025] A mixing structure is installed on the top of the mixing chamber 1. The mixing structure includes a mounting frame 8, on which a motor 9 is fixedly connected. The motor 9 is also fixed to the side of the mounting frame 8 and to the top wall of the mixing chamber 1. The motor 9 is installed at the top center to avoid eccentric wear of the side-mounted shaft. The output shaft of the motor 9 is inserted vertically downward into the mixing chamber 1 and is connected to a mixing shaft 10. A mixing blade 11 is installed on the mixing shaft 10. The mixing shaft 10 and the mixing blade 11 rotate under the drive of the motor 9 to achieve fertilizer mixing and blending.

[0026] The bottom of the mixing chamber 1 is equipped with a discharge mechanism, which includes four discharge pipes 12 located at the bottom edge of the mixing chamber 1. The discharge pipes 12 provide a discharge path for controlling the discharge of the mixed fertilizer. Each discharge pipe 12 is equipped with a discharge valve 13. The discharge valve 13 allows for precise flow control, supports batch discharge, and adapts to different capacity collection buckets 4.

[0027] The specific design of the aforementioned key components will be discussed in detail below:

[0028] The mixing chamber 1 is made of stainless steel, and the inner wall of the mixing chamber 1 has a smooth surface. Stainless steel is corrosion-resistant and extends service life, while the smooth inner wall reduces the adhesion of high-humidity fertilizer. The material at the bottom of the mixing chamber 1 flows naturally to the discharge pipe 12. The collection bucket 4 is located at the center of the bottom of the mixing chamber 1. The collection bucket 4 is a movable bucket that is separate from the mixing chamber 1. The movable and detachable design of the collection bucket 4 facilitates transportation and movement.

[0029] The stirring blades 11 are helical blades made of wear-resistant alloy steel, and are arranged in multiple staggered layers along the stirring shaft 10. The multi-layered helical blades provide a bidirectional flow field in both axial and radial directions, resulting in high mixing uniformity. The wear-resistant alloy steel blades are resistant to fertilizer particle wear and have a long service life.

[0030] The outlet end of each discharge pipe 12 is provided with an arc-shaped bend towards the center of the collection bucket 4. The material is guided to the collection bucket 4 along the arc-shaped bend, the landing point is concentrated, the radial splashing is eliminated, there is no accumulation at the edge of the collection bucket 4, no need for manual leveling, the collection bucket 4 cooperates with the arc-shaped discharge pipe 12 to receive the material, and the material falls accurately.

[0031] In a preferred embodiment, the edge of the feed door 5 is fitted with a sealing rubber strip. When closed, the rubber strip deforms elastically to fill the gap between the door and the top of the silo. A reinforcing rib is provided at the connection between the support column 2 and the support 3. A triangular steel plate is added at the welding joint of the support column 2 and the support 3 to improve the bending stiffness. The rib is integrally welded to the support column 2 / support 3, without the need for additional assembly.

[0032] The stirring shaft 10 is made of carbon steel, and the stirring blades 11 are made of wear-resistant alloy steel or engineering plastic. Both the stirring shaft 10 and the stirring blades 11 are coated with an anti-corrosion coating. Through the composite protection of the base material and the surface coating, it resists the chemical corrosion of fertilizer and the physical wear caused by fertilizer impact.

[0033] The inner wall of the discharge pipe 12 is smooth. The angle between the central axis of the arc-shaped bend at the outlet end of the discharge pipe 12 and the vertical direction is 10°-25°. 10°-15° is suitable for low-speed powdered fertilizers, producing a gentle parabola and concentrated impact point; 16°-25° is used for high-speed granular fertilizers, utilizing inertial focusing to reduce splashing. The angle range covers mainstream fertilizer types including powders, granules, and organic fertilizers, with 15° being the preferred universal angle. The smooth inner wall reduces material flow resistance and prevents sticky fertilizers from adhering to the wall; the arc-shaped bend controls the material projection trajectory, achieving centripetal convergence.
