Description

Technical Field

[0001] The utility model relates to the technical field of agricultural fertilizer processing devices, in particular to an agricultural fertilizer mixing device. Background Art

[0002] Agricultural fertilizers are essential nutritional supplements in agricultural production. They can provide various nutrients required for plant growth and help improve crop yield and quality. However, there are some problems with agricultural fertilizers during transportation, storage and use. One of them is that they are easily affected by moisture or agglomerated due to long-term storage. This requires the fertilizer to be pre-crushed before blending, otherwise it will affect the subsequent blending work.

[0003] Traditional blending devices have some defects, including the lack of crushing ability. Crushing is required before blending, which increases the process and work intensity. In addition, when blending agglomerated fertilizers, problems such as uneven blending and equipment shutdown due to overload will occur. In addition, fertilizers are easily attached to the inner wall of the blender, resulting in some fertilizers not being fully blended, affecting the uniformity and efficiency of blending. Utility Model Content

[0004] The utility model provides an agricultural fertilizer blending device to solve various problems that traditional blending equipment has no crushing ability and fertilizers are easily attached to the inner wall.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: an agricultural fertilizer blending device, comprising a base frame and a blending box fixedly arranged on the upper end surface of the base frame, a feed port is arranged at the upper end of the blending box, a discharge port is arranged at the bottom of the side of the blending box, the upper end of the feed port is connected to a crushing box with openings at both upper and lower ends, a double-roll crusher is arranged inside the crushing box, a spiral agitator is rotatably arranged on the bottom surface of the inner part of the blending box, a motor for driving the spiral agitator to rotate is fixedly arranged on the bottom surface of the blending box, a rectangular frame is fixedly arranged at the bottom of the rotating shaft of the spiral agitator, and cleaning components for cleaning the inner wall of the blending box are fixedly arranged on both left and right sides of the rectangular frame.

[0006] Furthermore, the cleaning component includes brushes fixedly arranged on the left and right sides of the rectangular frame, and the brushes are in contact with the inner wall of the mixing box.

[0007] Furthermore, a material screening component is fixedly provided inside the crushing box and below the double-roll mill, and an impurity outlet is provided on the side of the crushing box corresponding to the lowest point of the material screening component.

[0008] Furthermore, the material screening assembly includes a screen plate fixedly arranged inside the crushing box, and an oscillation motor is fixedly arranged at the bottom center of the screen plate.

[0009] Furthermore, the sieve plate is arranged to be inclined at 30° toward the impurity outlet.

[0010] Compared with the prior art, the utility model has the following advantages: the new agricultural fertilizer blending device solves the problems existing in the traditional blending device by introducing innovative designs such as a crushing box and a cleaning component. A double-roll crusher and a material screening component are provided inside the crushing box, which can crush and screen the fertilizer during the blending process, reduce the pretreatment work caused by fertilizer agglomeration, and improve the blendability of the fertilizer. At the same time, the cleaning component can clean the inner wall of the blending box in time, reduce the fertilizer residue attached to the wall, and ensure the uniformity and efficiency of the blending process. Therefore, the new blending device has the advantages of high blending efficiency, simple operation, and uniform blending, and can effectively improve the utilization rate of fertilizers and the growth quality of crops in agricultural production.
