Technical Field
[0001] This utility model relates to the field of fertilizer controlled release technology, and in particular to a fertilizer controlled release device. Background Technology
[0002] Controlled-release fertilizers are an advanced form of slow-release fertilizers. They primarily use coating technology to control nutrient release, achieving safety, long-lasting effects, and high efficiency. This represents a major direction in modern fertilizer development and is suitable for mechanized production, particularly for simultaneous seed and fertilizer application. Fertilizers produced using coating technology are generally called coated fertilizers, also known as coated fertilizers. These are water-soluble fertilizer granules coated with a semi-permeable or insoluble film, exhibiting the characteristic of slow nutrient release.
[0003] During the production of coated fertilizers, the fertilizer granules need to be coated. Generally, this is done by adding the coating agent powder and fertilizer together into a roller coating machine, so that the fertilizer and coating agent are mixed to form a coating.
[0004] However, in actual operation, the film powder continuously collides with the fertilizer particles in the roller coating machine in a disorderly manner. This process is uncontrollable and is prone to uneven coating of fertilizer, which affects the quality of coated fertilizer. At the same time, when the amount of powder used is too large, it is easy to waste powder. Therefore, this application proposes a fertilizer controlled release device. Summary of the Invention
[0005] Therefore, it is necessary to provide a fertilizer controlled-release device to address the above-mentioned technical problems. Through the overall structural design, after adding sufficient fertilizer and film powder into the coating roller through the feed seat, controlling the rotation of the rotating shaft and the spiral conveyor blades can drive the fertilizer and film powder in the coating roller to be conveyed towards the discharge seat, while making them fully stirred and mixed, so that the fertilizer particles can be evenly coated by the film powder, effectively reducing the phenomenon of uneven fertilizer coating.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A fertilizer controlled-release device, which is used for fertilizer controlled release; The device includes a first upright and a second upright, with a coating roller rotatably connected between the two uprights. The coating roller has multiple filter holes evenly spaced inside. An L-shaped support is fixed to the end of the first upright away from the second upright and outside the coating roller. A discharge seat is fixed to the end of the second upright away from the first upright and outside the coating roller. An inlet seat is fixed to the upper end of the L-shaped support, and the inlet seat is in contact with the coating roller. The discharge seat is rotatably connected to the coating roller. A rotating shaft is located at the center of the inner side of the coating roller. A spiral conveying blade is fixed to the outer side of the rotating shaft, and the outer side of the spiral conveying blade is in contact with the coating roller and the inlet seat. Both ends of the rotating shaft are rotatably connected to the inlet seat and the discharge seat, respectively. A base plate is attached to the bottom end of the discharge seat.
[0007] In a preferred embodiment of the fertilizer controlled-release device provided by this utility model, a recycling box is fixed to one end of the second stand near the first stand and outside the plurality of filter holes, and a first flat gear is fixed to the outer side of the coating roller near the first stand.
[0008] In a preferred embodiment of the fertilizer controlled-release device provided by this utility model, a first motor is fixed at the lower end of the first frame and outside the first spur gear, and a second spur gear is fixed at the output end of the first motor, and the second spur gear meshes with the first spur gear.
[0009] In a preferred embodiment of the fertilizer controlled-release device provided by this utility model, a top plate is fixed to the top of the discharge seat, a hot air circulator is installed on the upper end of the top plate, air guide pipes are fixedly connected to both sides of the hot air circulator, and a wind hood is fixed to the end of each air guide pipe away from the hot air circulator. The wind hood is located inside the discharge seat and communicates with the discharge seat.
[0010] In a preferred embodiment of the fertilizer controlled-release device provided by this utility model, a telescopic cylinder and a second motor are respectively fixed at the bottom end of the top plate and outside the discharge seat. The telescopic end of the telescopic cylinder is fixed to the bottom plate, and a second bevel gear is fixed at the output end of the second motor.
[0011] In a preferred embodiment of the fertilizer controlled-release device provided by this utility model, a turning blade is fixed on the outer side of the rotating shaft and on the inner side of the discharge seat. The turning blade is located between two wind hoods. A first bevel gear is fixed on the outer side of the rotating shaft and on the outer side of the discharge seat. The first bevel gear is meshed with a second bevel gear.
[0012] Compared with the prior art, the present invention has the following beneficial effects: The fertilizer controlled-release device provided by this utility model, through its overall structural design, enables the fertilizer and film powder to be synchronously conveyed towards the discharge seat after sufficient fertilizer and film powder are added into the coating roller through the feeding seat. This allows the rotating shaft and spiral conveyor blades to rotate, ensuring that the fertilizer and film powder in the coating roller are fully mixed. This ensures that the fertilizer particles are evenly coated by the film powder, effectively reducing uneven fertilizer coating caused by insufficient mixing. The meshing of the first and second spur gears facilitates the opening and closing of the first motor to control the rotation of the coating roller, thereby adjusting the position of multiple filter holes. When the multiple filter holes move to the bottom of the coating roller, excess membrane powder can fall into the recycling box through the multiple filter holes during the conveying process for collection, thereby realizing the recycling of excess membrane powder and reducing waste. The hot air circulation machine, along with two air ducts and a hood, facilitates continuous hot air circulation to dry the fertilizer in the discharge seat, thus shaping it. During this process, the continuous rotation of the shaft drives the turning blades to flip the fertilizer, which facilitates continuous turning of the fertilizer in the discharge seat, improving drying efficiency and enhancing the quality of the produced coated fertilizer.
