[0002] Organic fertilizers are mainly derived from plants and (or) animals. They are carbon-containing materials applied to the soil with the main function of providing plant nutrition. They are processed from biological materials, animal and plant waste, and plant residues, eliminating toxic and harmful substances. They are rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. They can not only provide comprehensive nutrition for crops, but also have long-lasting fertilizer effects, increase and renew soil organic matter, promote microbial reproduction, and improve the physical and chemical properties and biological activity of the soil. They are the main nutrients for green food production.
[0003] Organic fertilizer needs to go through a series of processing, production and fermentation. Before fermentation, the organic fertilizer must be thoroughly dried. Traditional organic fertilizer drying does not have special drying equipment. It only dries the organic fertilizer through some kind of heat source. This can easily lead to excessive accumulation of organic fertilizer, affecting the drying efficiency and making the organic fertilizer not dried thoroughly. At the same time, some use drum-type drying devices to dry organic fertilizer, but during the drying process, the organic fertilizer cannot be brought to the upper side of the drum and can only be rolled and dried in the middle and lower sides, resulting in poor drying effect.

In order to prevent the organic fertilizer from accumulating outside the pushing drum 11, spiral blades are provided on the inner wall of the pushing drum 11. When the drying drum 1 rotates, the pushing drum 11 rotates accordingly and drives the spiral blades to rotate, pushing the organic fertilizer at the pushing drum 11 into the inside of the drying drum 1. The right end of the pushing drum 11 is rotatably connected to the front head 12, and the left end of the drying drum 1 is rotatably connected to the rear head 13. A frame 15 is provided at the lower end of the drying drum 1.

A motor 17 is fixed to the frame 15, which is transmission-connected to the drying drum 1. The supporting rollers 16 support the drying drum 1. While supporting the drying drum 1, the supporting rollers 16 do not affect the rotation of the drying drum 1. The motor 17 and the reducer 18 cooperate with the gear ring 19 on the drying drum 1 to drive the drying drum 1, thereby driving the drying drum 1 to rotate, and then the organic fertilizer inside the drying drum 1 is flipped to ensure the drying of the organic fertilizer.

[0024] See also Figure 2 、 Figure 3 and Figure 4, the interior of the drying cylinder 1 is provided with two bilaterally symmetrical fixing rings 2, the two fixing rings 2 rotate synchronously, and a plurality of copying plates 4 are detachably connected between the two fixing rings 2, the fixing ring 2 is used to fix the copying plates 4, and the copying plates 4 are used to flip the organic fertilizer inside the drying cylinder 1 to ensure that the organic fertilizer is evenly dried, and a belt barrel 6 is provided between each of the copying plates 4, and a fixing ring 5 fixedly connected to the drying cylinder 1 is provided between the two fixing rings 2, and a plurality of belt barrels 6 are provided between the fixing ring 5 and the fixing ring 2, one end of the belt barrel 6 is detachably connected to the fixing ring 5, and the other end of the belt barrel 6 is detachably connected to a fixed block 3, so The fixed block 3 is fixedly connected to the fixing ring 2, and the fixed block 3 is slidably connected to the inner wall of the drying cylinder 1. The fixed block 3 fixes the copying plate 4 and the belt barrel 6. When the threaded rod 31 is rotated, the fixed block 3 and the fixing ring 2 approach the copying plate 4, and the wedge-shaped groove 32 clamps and fixes the copying plate 4. Since the fixed block 3 is close to the end of the belt barrel 6, two symmetrical wedge-shaped grooves 32 are opened, and the wedge-shaped grooves 32 are isosceles trapezoidal. The outer opening of the wedge-shaped groove 32 is large and the inner opening is small. When the fixed block 3 squeezes the copying plate 4, the wedge-shaped groove 32 squeezes and fixes the copying plate 4 in the center. In actual use, the copying plate 4 can also be directly welded to the inner wall of the drying cylinder 1.

The organic fertilizer inside the drying drum 1 is observed through the observation window 123, so as to clearly understand the drying degree of the organic fertilizer inside the drying drum 1.
[0026] See also Figure 3 、 Figure 4 and Figure 5The copy board 4 includes a first copy board, a second copy board and a third copy board. One end of the first copy board, the second copy board and the third copy board are all folded. The first copy board is bent 120 degrees, the second copy board is bent 135 degrees, and the third copy board is bent twice and each time is bent 135 degrees. The organic fertilizer in the drying drum 1 is moved by the copy board 4, which is conducive to driving the organic fertilizer at the lower end of the drying drum 1 to the top of the drying drum 1 and then making it fall, thereby increasing the contact time and area between the organic fertilizer and the hot air, thereby ensuring the drying effect of the organic fertilizer.

The copying plate 4 is clamped and fixed through the fixing holes 51 on the fixing ring 5, which plays a role of supporting the copying plate 4 and preventing the copying plate 4 from bending and deforming when a large amount of organic fertilizer is moved.
[0028] When using this utility model:
[0029] First, an external heat source is introduced into the interior of the drying drum 1, and the motor 17 is started to work. The motor 17 and the reducer 18 drive the drying drum 1 to rotate, and the organic fertilizer is transported into the interior of the drying drum 1 through the feed port 121;
[0030] Then, when the drying drum 1 rotates, the pushing drum 11 rotates accordingly, thereby driving the spiral blade to rotate, pushing the organic fertilizer at the pushing drum 11 into the interior of the drying drum 1, thereby preventing the organic fertilizer from accumulating at the pushing drum 11;
[0031] Next, after the organic fertilizer enters the interior of the drying drum 1, the lifting plate 4 stirs the organic fertilizer in the drying drum 1, which is conducive to driving the organic fertilizer at the lower end of the drying drum 1 to the top of the drying drum 1 and then causing it to fall, thereby increasing the contact time and area between the organic fertilizer and the hot air, thereby ensuring the drying effect of the organic fertilizer. Part of the organic fertilizer will enter the cavity of the belt barrel 6. When the drying drum 1 rotates, the discharging through-hole 61 discharges the organic fertilizer in an intermittent state, thereby preventing the organic fertilizer from falling in large quantities, resulting in part of the organic fertilizer being unable to contact with the hot air, thereby affecting the drying of the organic fertilizer.
[0032] Finally, the moisture generated by drying is discharged through the moisture outlet 131 , and the organic fertilizer after drying is discharged through the material outlet 132 .
