Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer drying, in particular to an organic fertilizer hot air drying machine. Background Art

[0002] Organic fertilizer is a fertilizer rich in beneficial substances, including a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. It can provide high-quality nutrients for the growth of crops, thereby improving the physical and chemical properties and biological activity of the soil, improving the quality of crops and increasing crop yields. It is an indispensable and important guarantee in agricultural production.

[0003] In the process of organic fertilizer production, it is usually necessary to crush and dry the fermented organic fertilizer raw materials. The existing drying equipment is generally a cylindrical drying drum with a built-in turning plate or rotating disk, and then a heating source is set. The organic fertilizer raw materials are turned and dried by the continuous rotation of the drying drum. However, such a structure has the following problems: 1. During the drying process, the organic fertilizer raw materials cannot be fully stirred only by rotating the drying drum. Some organic fertilizers are always stacked together, and the water is not easy to disperse, which easily causes the organic fertilizer to clump. 2. The heating source is generally an electric heating wire. The temperature of the electric heating wire is not easy to control, which easily causes uneven baking of the fertilizer and affects the drying quality of the organic fertilizer.

[0004] The Chinese utility model patent with document number CN216845586U discloses a jet drying device for organic fertilizer production, including a drying box, a drying mechanism and a screening mechanism. An installation hole is opened on the outer wall of the drying box, and a material feeding hole is fixedly installed on the installation hole. The drying mechanism is arranged on the top of the drying box, and the screening mechanism is arranged inside the drying box. The jet drying device for organic fertilizer production uses a cylinder, a telescopic rod, a hot air blower, a hose and a drying disc. The cylinder can be extended to evenly dry the fertilizer on the installation plate, and the crushing blade can crush the lumped and difficult-to-dry fertilizer to prevent the fertilizer from lumping after drying. The work efficiency of the staff is improved, the scope of use of the device is expanded, and it is conducive to promotion and use.

[0005] However, in this structure, although a crushing device and a shaking device are added compared to the traditional structure, since the crushing blade is fixedly installed at the bottom of the disc, the position of the crushing blade cannot be adjusted according to actual conditions, which results in it being unable to effectively crush the agglomerated and difficult-to-dry fertilizers. At the same time, the coordinated use of the mounting plate, motor, spring, screen box and eccentric wheel cannot effectively realize the drying and screening function of the fertilizer. There may be a situation where undried fertilizer passes through the filter screen in advance and falls. There is also a gap between the mounting plate and the spring and eccentric wheel, and the agglomerated fertilizer may fall from the gap, and the drying effect and drying quality of the fertilizer cannot be guaranteed.
