[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] The so-called rotational connection in this device means that the bearing is baked and installed on the shaft, and a spring retaining ring groove is provided on the shaft or the shaft hole. The axial fixation of the bearing is achieved by clamping the elastic retaining ring in the retaining ring groove to realize rotation; the so-called hinge connection means a connection method that moves on connecting parts such as hinges, pin shafts, and short shafts.

[0015] The present utility model will be described in detail below in conjunction with the accompanying drawings.

[0016] Embodiment 1:

[0017] Next, in combination with the attached Figure 1-2 This embodiment will illustrate a granulated organic fertilizer turning and drying device, including: a drying outer shell 1, a heating element is provided inside the drying outer shell 1, a plurality of material turning chambers 2 are horizontally arranged inside the drying outer shell 1, a feed inlet 3 and a discharge outlet 4 are respectively provided at the upper and lower parts of the material turning chambers 2 at both ends of the drying outer shell 1, adjacent material turning chambers 2 are connected and communicated through a fertilizer channel 5, the fertilizer channel 5 is located at the lower part and is inclined from high to low along the feeding direction, a material turning shaft 6 is rotationally connected to the outer wall of the drying outer shell 1 at the axis center of each material turning chamber 2, the material turning shaft 6 is connected to a material turning blade 7, the outer edge of the material turning blade 7 is in contact with the inner wall of the material turning chamber 2, and an exhaust hole 8 is opened on the outer wall of the drying outer shell 1 at the upper part of each material turning chamber 2;

[0018] The fertilizer to be dried is continuously and evenly injected into the turning chamber 2 through the feed inlet 3. The power of the turning shaft 6 is turned on, and the turning shaft 6 drives the turning blades 7 to rotate. The outer edge of the turning blade 7 contacts the inner wall of the turning chamber 2. The turning blade 7 can drive the fertilizer to turn in the turning chamber 2 without omission until the fertilizer moves to the fertilizer channel 5. The fertilizer channel 5 is located at the lower part and is inclined from high to low along the feeding direction. The fertilizer enters the next turning chamber 2 along the fertilizer channel 5 until it is discharged through the discharge port 4, realizing continuous drying. When conveying, a high-temperature and high-pressure space is formed in the space composed of two turning blades 7, and the heat will not be lost, so the temperature of the fertilizer rises quickly until this space moves to the exhaust hole 8, the pressure drops suddenly, and under the high-temperature condition, the moisture evaporates quickly and the water vapor is discharged quickly to complete moisture removal.

[0019] The turning shaft 6 at the feed inlet 3 is connected to the intermediate shaft 10 through the gear set 9. The intermediate shaft 10 is rotatably connected to the drying housing 1. The intermediate shaft 10 is connected to the turning shaft 6 adjacent along the conveying direction through the belt drive 11. The turning shafts 6 adjacent along the conveying direction are connected through the belt drive 11.

[0020] The rotation direction of the subsequent turning shafts 6 is changed through the gear set 9. The rotation direction of the first turning blade 7 is different from that of the subsequent turning blades 7. In this way, the movement path of the fertilizer driven by the turning blade 7 at any position is the farthest path, increasing the drying stroke and improving the drying effect.

[0021] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.
