[0023] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0024] A method for preparing an environmentally friendly fertilizer comprises the following steps:

[0025] Step 1: Add the fertilizer particles to be dried into the discharging mechanism, and use the discharging mechanism to loosen and discharging the fertilizer particles intermittently and quantitatively;

[0026] Step 2: loosening the agglomerated fertilizer particles through a conveying mechanism;

[0027] Step 3: Screening the fertilizer particles through the conveying mechanism to remove the debris in the fertilizer particles;

[0028] Step 4: The hot air mechanism forms flowing hot air inside the conveying mechanism to dehydrate and dry the fertilizer particles to obtain environmentally friendly fertilizer;

[0029] Step 5: The screened fertilizer residue is collected and processed by the air flow generated by the hot air mechanism.

[0030] See also Figure 1-5 , showing a schematic diagram of an embodiment of the present invention capable of achieving loose processing of fertilizer particles, further,

[0031] The discharging mechanism is connected to the conveying mechanism, and the hot air mechanism is connected to the front end of the conveying mechanism. The discharging mechanism includes a storage box 401, and a loosening roller 402 is rotatably connected to the storage box 401 through a bearing. A plurality of ridges that can break up the fertilizer particles are evenly arranged on the loosening roller 402, and the plurality of ridges are integrally formed with the loosening roller 402. A discharging plate 501 is slidably connected to the bottom of the storage box 401, and a groove for inserting the discharging plate 501 is provided at the bottom of the storage box 401, and the discharging plate 501 cooperates with the groove to achieve sliding.

[0032] When using this device, the staff adds the fertilizer particles to be dried into the storage box 401, and then controls the loosening roller 402 to rotate. Since the loosening roller 402 is evenly arranged with multiple ridges that can break up the fertilizer particles, and there is a gap between the loosening roller 402 and the inner wall of the storage box 401, the fertilizer particles fall between the loosening roller 402 and the inner wall of the storage box 401. When the loosening roller 402 rotates, it cooperates with the inner wall of the storage box 401 to break up the fertilizer particles, thereby preventing the fertilizer particles from agglomerating.

[0033] By controlling the discharge plate 501 to slide at the bottom of the storage box 401 , the discharge plate 501 is opened, and the fertilizer particles can be automatically discharged from the storage box 401 .

[0034] See also Figure 5 , shows a schematic diagram of an embodiment of the present invention capable of realizing the quantitative discharging function, and further,

[0035] The device also includes a paddle 403, which is welded and fixedly connected to the loosening roller 402. A trapezoidal groove 502 is provided on the discharge plate 501, and a tension spring 503 is fixedly connected between the discharge plate 501 and the storage box 401 through a hook.

[0036] When the device is used, the loosening roller 402 rotates to drive the paddle 403 to rotate. When the paddle 403 rotates downward, it enters the trapezoidal groove 502. The paddle 403 cooperates with the trapezoidal groove 502 to enable the paddle 403 to push the discharge plate 501 to slide forward, thereby opening the discharge plate 501 and automatically discharging the fertilizer particles. At this time, the tension spring 503 is in a stretched state. When the paddle 403 starts to rotate upward, the paddle 403 disengages from the trapezoidal groove 502, and then the paddle 403 no longer contacts the discharge plate 501. At this time, the discharge plate 501 is reset under the elastic action of the tension spring 503, thereby realizing the intermittent quantitative discharge function, which can prevent the phenomenon of pile blockage caused by the later processing of the fertilizer particles.

[0037] See also Fig. 9 , showing a schematic diagram of an embodiment of the present invention capable of conveying and screening fertilizer particles, further,

[0038] The conveying mechanism comprises a belt conveyor, on which a conveyor belt (201) for conveying materials is provided, the conveyor belt (201) being sleeved on two rollers to achieve a material conveying function, a plurality of sieve holes being provided on the conveyor belt (201), the conveyor belt (201) being located below the material storage box (401), and the conveyor belt 201 being arranged to be tilted backwards.

[0039] When the device is used, the fertilizer particles in the storage box 401 fall onto the conveyor belt 201, and the conveyor belt 201 rotates to convey the fertilizer particles backwards. Since the conveyor belt 201 is tilted backwards, it is more convenient to convey the fertilizer particles, so that unqualified debris contained in the fertilizer particles can fall through the multiple sieve holes on the conveyor belt 201, thereby screening the fertilizer particles and improving the quality of the fertilizer.

[0040] See also Figure 1 , Fig. 9 , showing a schematic diagram of an embodiment of the present invention in which fertilizer can be dried, further,

[0041] The hot air mechanism includes a hot air box 101, the front end of the hot air box 101 is welded and fixedly connected with an air inlet pipe 102, two rollers on the conveyor belt 201 are rotatably connected to the hot air box 101 through bearings, a drive motor 602 is fixedly connected to the hot air box 101 by bolts, the roller at one end of the conveyor belt 201 is fixedly connected to the output shaft of the drive motor 602 through a coupling, one end of the conveyor belt 201 is connected to the loosening roller 402 through a pulley 601, the pulley 601 is a combination of a belt and two pulleys, one pulley is fixedly connected to the loosening roller 402 by a key, and the other wheel is fixedly connected to one end of the conveyor belt 201 by a key, a material guide plate 204 is welded and fixedly connected to the hot air box 101, and two baffles for blocking the conveyor belt 201 are extended from the material guide plate 204, and the hot air box 101 is arranged to be tilted backward and parallel to the conveyor belt 201.

[0042] When using the device, the staff connects the air inlet pipe 102 to the existing electric hot air blower through a rubber hose, and provides hot air to the hot air box 101 through the hot air blower. The hot air in the hot air box 101 dries the fertilizer particles above it through the conveyor belt 201, and the screened fertilizer particle residue falls into the hot air box 101. The hot air flow generated in the hot air box 101 blows the fertilizer particle residue to the rear end.

[0043] The conveyor belt 201 and the loosening roller 402 can be controlled synchronously through the pulley 601 to ensure the production efficiency of the fertilizer particles and further prevent the accumulation of fertilizers. The driving motor 602 provides driving force for the roller at one end of the conveyor belt 201.

[0044] See also Figure 8 , showing a schematic diagram of an embodiment of the present invention capable of further loosening fertilizer particles, further,

[0045] The conveying mechanism also includes two connecting members 304, on which a washboard 301 is slidably connected, and both connecting members 304 are slidably connected to the hot air box 101. A plurality of round rods are welded on the two connecting members 304, and the washboard 301 is provided with two round holes, wherein two round rods respectively cooperate with the two round holes to achieve sliding, and the hot air box 101 is provided with two matching holes, and the other two round rods respectively cooperate with the two matching holes to achieve sliding, and a plurality of rectangular blocks are evenly arranged at the lower end of the washboard 301, and the plurality of rectangular blocks are integrally formed with the washboard 301, and two springs 306 are respectively welded and fixedly connected between the two connecting members 304 and the washboard 301, and two compression springs 305 are respectively welded and fixedly connected between the two connecting members 304 and the hot air box 101, and rectangular grooves 202 are provided on the upper and lower surfaces of the conveyor belt 201.

[0046] When using this device, the rubbing board 301 can slide left and right through the two round holes and the two round rods on the two connecting parts 304. Through the elastic action of the two springs 306, the rubbing board 301 has the function of reciprocating sliding, and then the rubbing board 301 can drive multiple rectangular blocks to move back and forth. Under the manipulation of multiple rectangular blocks, most of the fertilizer particles can enter the rectangular groove 202. The multiple rectangular blocks cooperate with the rectangular groove 202 on the conveyor belt 201 to crush larger lumps, thereby achieving the purpose of loosening the fertilizer particles. In order to avoid the phenomenon of linear stacking due to large lumps, under the elastic action of the two compression springs 305, the two connecting parts 304 are made elastic relative to the hot air box 101, thereby making the rubbing board 301 elastic in the direction perpendicular to the conveyor belt 201.

[0047] See also Figure 7-8 , shows a schematic diagram of an embodiment of the present invention that can realize the reciprocating sliding of the washboard 301, further,

[0048] The conveying mechanism also includes a contact wheel 203. Two contact wheels 203 are rotatably connected to the conveyor belt 201 through an axis. The two contact wheels 203 are respectively located at the front end and the rear end of the conveyor belt 201. A corrugated protrusion 303 is opened at the left end of the washboard 301.

[0049] As the conveyor belt 201 rotates, the two contact wheels 203 are driven to move. The two contact wheels 203 can come into contact with the corrugated protrusion 303 at the left end of the washboard 301, and cooperate with the two springs 306 to make the washboard 301 slide back and forth. Since the two contact wheels 203 are respectively located at the front and rear ends of the conveyor belt 201, the reciprocating sliding of the washboard 301 is uninterrupted. After coming into contact with the corrugated protrusion 303, the contact wheel 203 will rotate. The purpose of this design is to avoid large dry friction and abnormal noise between other contact parts and the corrugated protrusion 303.

[0050] See also Figure 8 , shows a schematic diagram of an embodiment of the present invention capable of achieving hot air circulation, and further,

[0051] A plurality of air outlets 302 are provided on the washboard 301, and the plurality of air outlets 302 have the function of discharging moisture, ensuring the circulation of hot air, and enhancing the drying effect of the fertilizer.

[0052] See also Figure 10-11 , showing the intention of the embodiment according to the present invention to facilitate the collection of fertilizer residues, further,

[0053] The hot air mechanism further comprises a collecting box 103 , which is fixedly connected to the rear end of the hot air box 101 by means of bolts, and a sliding door 104 is slidably connected to the bottom of the collecting box 103 .

[0054] When the device is used, the collecting box 103 collects fertilizer debris. The fertilizer particles are discharged from the upper end of the collecting box 103 after being conveyed by the conveyor belt 201. The fertilizer debris collected in the collecting box 103 can be discharged by sliding the sliding door 104 open.

[0055] See also Fig.11 , showing the intention of the embodiment of the present invention that wind flow can be formed to facilitate the collection of fertilizer residues, and further,

[0056] An exhaust duct 105 is welded and fixedly connected to the collecting box 103. The function of the exhaust duct 105 is to allow part of the hot air to be discharged from the collecting box 103, thereby forming an air flow between the hot air box 101 and the collecting box 103, so as to facilitate blowing the screened fertilizer residue into the collecting box 103. The exhaust duct 105 has a small exhaust volume relative to the multiple exhaust ports 302, so that most of the hot air can still be discharged from the multiple exhaust ports 302, thereby ensuring the drying efficiency of the fertilizer particles.
