Description

Technical Field

[0001] This invention relates to the field of compound organic fertilizer processing, and more specifically to a compound organic fertilizer and its processing method. Background Technology

[0002] Compound fertilizers are substances that provide two or more essential nutrients for plants, improve soil properties, and enhance soil fertility, forming one of the material foundations of agricultural production. The preparation of compound fertilizers requires the proportioning of different raw materials; pulverized raw materials are easier to blend. Existing organic compound fertilizers are generally in solid granular form and are often applied to the roots of crops manually, allowing nutrients to be transported from the roots to the entire plant. However, the granulation process requires drying the granular organic compound fertilizer while constantly turning it over. Excessive turning force can cause granule breakage, while insufficient force will result in incomplete drying. To address these issues, a compound organic fertilizer and its processing method need to be designed. Summary of the Invention

[0003] This invention provides a compound organic fertilizer and its processing method, the purpose of which is to uniformly turn over the granular organic compound fertilizer to prevent the granules from being crushed.

[0004] A method for processing compound organic fertilizer, the method comprising the following steps:

[0005] Step 1: Prepare the raw materials for compound organic fertilizer by crushing and mixing the raw materials;

[0006] Step 2: Add lime water to the crushed raw materials to compost and ferment them.

[0007] Step 3: Place the fermented raw materials into the processing device and extrude and granulate them.

[0008] Step 4: Dry and screen the granular compound organic fertilizer;

[0009] Step 5: Take out the screened granular compound organic fertilizer and store it for later use.

[0010] The raw materials for the compound organic fertilizer include: straw, poultry and livestock manure, urea, monoammonium phosphate and potassium sulfate.

[0011] In step one, the straw in the raw materials needs to be dried and chopped.

[0012] In step two, the mass ratio of lime water to raw materials is 25:1, and the mixture is sealed and fermented at room temperature.

[0013] In step three, an appropriate amount of talc powder is added during the drying process of the granular compound organic fertilizer.

[0014] The processing device includes an extrusion cylinder, a top cover I fixedly connected to the extrusion cylinder, a support shell fixedly connected to the top cover I, and a motor fixedly connected to the support shell; the output shaft of the motor passes through the support shell, a drive rod is fixedly connected below the output shaft of the motor, a slide cylinder is slidably connected to the drive rod, a sliding wedge is rotatably connected to the inner side of the slide cylinder, the drive rod is provided with two opposite and connected spiral grooves, and the sliding wedge is slidably connected in the two spiral grooves; an extruder is fixedly connected below the slide cylinder, and a granulation plate is fixedly connected below the extrusion cylinder.

[0015] The extruder has rotating shafts I fixedly connected to both its left and right sides, and the extrusion cylinder has slots I on both its left and right sides. The two rotating shafts I are slidably connected in the two slots I respectively.

[0016] A feeding cylinder is fixedly connected to the lower part of the extrusion cylinder, and a support plate I is fixedly connected inside the feeding cylinder; a drive rod passes through the extruder and the granulation plate, and a rotating rod I is fixedly connected to the lower part of the drive rod, which is rotatably connected to the support plate I; multiple rotating blades are fixedly connected to the rotating rod I, and each rotating blade is in close contact with the lower part of the granulation plate; a spiral plate I is fixedly connected to the rotating rod I.

[0017] A top cover II is fixedly connected to the bottom of the feeding cylinder, and a tilting box is fixedly connected to the bottom of the top cover II. A rotating plate is rotatably connected inside the tilting box, and a screen plate is slidably connected to both the front and rear sides of the rotating plate. A rotating shaft II is fixedly connected to both the left and right sides of each screen plate. Two slots II are provided on the left and right sides of the tilting box, and each rotating shaft II is slidably connected in the corresponding slot II. The two rotating shafts II on the front side are rotatably connected to two rotating shafts I respectively by connecting rods.

[0018] The compound organic fertilizer produced by the compound organic fertilizer processing method is characterized in that the raw material composition of the compound organic fertilizer includes: 15 parts by mass of straw, 60 parts by mass of poultry and livestock manure, 25 parts by mass of urea, 30 parts by mass of monoammonium phosphate and 35 parts by mass of potassium sulfate.

[0019] The beneficial effects of the compound organic fertilizer and its processing method of the present invention are as follows:

[0020] Compared to traditional compound organic fertilizers and their processing methods, this invention designs a turning box. The internal rotating plate and two sieve plates rotate alternately clockwise and counterclockwise to turn the granular compound organic fertilizer entering the box. This method reduces particle breakage caused by direct agitation and allows for bottom-level turning, resulting in more uniform drying. Furthermore, the sieve plate at the front moves up and down simultaneously with the extruder, enabling granulation and turning to occur concurrently, thus saving energy. Attached Figure Description

Detailed Implementation

[0035] A method for processing compound organic fertilizer, the method comprising the following steps:

[0036] Step 1: Prepare the raw materials for compound organic fertilizer by crushing and mixing the raw materials;

[0037] Step 2: Add lime water to the crushed raw materials to compost and ferment them.

[0038] Step 3: Place the fermented raw materials into the processing device and extrude and granulate them.

[0039] Step 4: Dry and screen the granular compound organic fertilizer;

[0040] Step 5: Take out the screened granular compound organic fertilizer and store it for later use.

[0041] The raw materials for compound organic fertilizer include: straw, poultry and livestock manure, urea, monoammonium phosphate and potassium sulfate. Specifically, the proportions are 15 parts straw, 60 parts poultry and livestock manure, 25 parts urea, 30 parts monoammonium phosphate and 35 parts potassium sulfate by weight.

[0042] Step one requires drying and chopping the straw in the raw materials.

[0043] In step two, the mass ratio of lime water to raw materials is 25:1. After sealing, fermentation is carried out at room temperature.

[0044] In step three, an appropriate amount of talc powder is added during the drying process of the granular compound organic fertilizer.

[0045] See Figure 1-13 This diagram illustrates an embodiment of the present invention in which the extruder 107 is driven to reciprocate in the up-down direction by rotating the drive rod 105. Further,

[0046] The processing device includes an extrusion cylinder 101, a top cover I 102 fixedly connected to the extrusion cylinder 101, a support shell 103 fixedly connected to the top cover I 102, and a motor 104 fixedly connected to the support shell 103. The output shaft of the motor 104 passes through the support shell 103, and a drive rod 105 is fixedly connected below the output shaft of the motor 104. A slide cylinder 106 is slidably connected to the drive rod 105, and a sliding wedge 110 is rotatably connected to the inner side of the slide cylinder 106. The drive rod 105 is provided with two opposite and connected spiral grooves, and the sliding wedge 110 is slidably connected in the two spiral grooves. An extruder 107 is fixedly connected below the slide cylinder 106, and a granulation plate 109 is fixedly connected below the extrusion cylinder 101.

[0047] The extrusion cylinder 101 supports the top cover I 102, which in turn supports the support shell 103. The support shell 103 provides a mounting position for the motor 104. The motor 104 drives the drive rod 105 to rotate via its output shaft. The rotation of the drive rod 105 drives the sliding wedge 110 to slide via the spiral groove, thereby enabling the sliding wedge 110 and the slide cylinder 106 to reciprocate in the up-down direction. The slide cylinder 106 drives the extruder 107 to move up and down. Each downward movement of the extruder 107 compresses the raw material, which is then extruded into long strips via the granulation plate 109.

[0048] See Figure 1-13 A schematic diagram of an embodiment of the invention in which the movement direction of the extruder 107 is limited by the rotating shaft I 108 is shown. Further,

[0049] The extruder 107 has rotating shafts I 108 fixedly connected to both the left and right sides, and the extrusion cylinder 101 has slots I on both the left and right sides. The two rotating shafts I 108 are slidably connected in the two slots I respectively.

[0050] The rotating shaft I 108 is slidably connected in the slot I, so that the extruder 107 can only slide in the up and down direction and cannot rotate with the drive rod 105, thus preventing it from affecting the up and down movement of the extruder 107 itself.

[0051] See Figure 1-13 This shows a schematic diagram of an embodiment of the present invention in which strip-shaped raw materials are cut into granules by means of a rotating blade 203. Further,

[0052] A feeding cylinder 201 is fixedly connected to the lower part of the extrusion cylinder 101, and a support plate I 205 is fixedly connected inside the feeding cylinder 201; a drive rod 105 passes through the extruder 107 and the granulation plate 109, and a rotating rod I 202 is fixedly connected to the lower part of the drive rod 105, and the rotating rod I 202 is rotatably connected to the support plate I 205; multiple rotating blades 203 are fixedly connected to the rotating rod I 202, and each rotating blade 203 is closely attached to the lower part of the granulation plate 109; a spiral plate I 204 is fixedly connected to the rotating rod I 202.

[0053] The feeding cylinder 201 is used to feed the produced granular compound organic fertilizer into the tilting box 402 below; the drive rod 105 can drive the rotating rod I 202 to rotate, which in turn drives the rotating cutter 203 to rotate. The rotating cutter 203 cuts the extruded strip-shaped organic fertilizer into granules, and the granular compound organic fertilizer falls downward onto the spiral plate I 204; the spiral plate I 204 rotates with the rotating rod I 202, conveying the granular compound organic fertilizer downward, and at the same time, through its own spiral shape, it extends the path of the organic fertilizer and prevents the granules from stacking and sticking together again.

[0054] See Figure 1-13This diagram illustrates an embodiment of the present invention, in which granular compound organic fertilizer is turned over and screened using a sieve plate 404. Further,

[0055] A top cover II 401 is fixedly connected to the bottom of the feeding cylinder 201, and a tilting box 402 is fixedly connected to the bottom of the top cover II 401. A rotating plate 403 is rotatably connected inside the tilting box 402. Screen plates 404 are slidably connected to both the front and rear sides of the rotating plate 403. Rotating shafts II 405 are fixedly connected to both the left and right sides of each screen plate 404. Two slots II are provided on the left and right sides of the tilting box 402 respectively. Each rotating shaft II 405 is slidably connected in the corresponding slot II. The two rotating shafts II 405 on the front side are rotatably connected to the two rotating shafts I 108 respectively by connecting rods 406.

[0056] The inside of the turning box 402 is ventilated and heated, and an appropriate amount of talcum powder is added to prevent the particles from sticking together again; the rotating plate 403 and the two sieve plates 404 are always on the same plane; as the extruder 107 moves up and down, it drives the rotating shaft I 108 to move up and down, which in turn drives the two rotating shafts II 405 and the corresponding sieve plates 404 located on the front side to move up and down through the connecting rod 406; when the sieve plates 404 located on the front side move up and down, they can slide inside the rotating plate 403, thereby driving the rotating plate Rotating plate 403 rotates clockwise and counterclockwise alternately, causing the rotating plate 403 and the two sieve plates 404 to rotate clockwise and counterclockwise alternately, thereby turning over the granular compound organic fertilizer that has entered the turning box 402. This method can reduce the breakage of particles caused by direct stirring, and at the same time, it can turn over the particles from the bottom, making the drying process more uniform. When the granular compound organic fertilizer dries and shrinks, its volume decreases, and it can fall down through the sieve holes on the sieve plate 404, thus completing the screening of particles.

[0057] See Figure 1-13 The diagram shows an embodiment of the present invention in which granular compound organic fertilizer is contained in a storage box 411. Further,

[0058] A support plate Ⅲ 408 is fixedly connected to the bottom of the tilting box 402. Four support columns 409 are fixedly connected to the bottom of the support plate Ⅲ 408. A base plate 410 is fixedly connected to the bottom of the support columns 409. A discharge cylinder 407 is connected to the bottom of the tilting box 402. A storage box 411 is fixedly connected to the base plate 410.

[0059] After screening, the granular compound organic fertilizer falls downwards and is stored in the storage box 411 through the discharge cylinder 407; the support plate Ⅲ 408, the support column 409 and the bottom plate 410 can support the entire processing device.

[0060] See Figure 1-13This diagram illustrates an embodiment of the present invention in which raw materials are fed into the extrusion cylinder 101 via a connecting pipe 301, a feed cylinder 302, and a feed hopper 303. Further,

[0061] A connecting pipe 301 is connected to the extrusion cylinder 101, and a feed cylinder 302 is fixedly connected to the connecting pipe 301. A feed hopper 303 is fixedly connected to the feed cylinder 302. Two support plates II 304 are fixedly connected inside the feed cylinder 302. Rotating rods II 305 are rotatably connected to the two support plates II 304. Spiral plates II 306 are fixedly connected to the rotating rods II 305. The rotating rods II 305 pass through the support plates II 304 located above. A rotating wheel I 307 is fixedly connected to the rotating rods II 305. A rotating wheel II 308 is fixedly connected to the drive rod 105. A transmission belt 309 is connected between the rotating wheels I 307 and the rotating wheels II 308. A baffle 310 is fixedly connected inside the feed hopper 303.

[0062] Raw materials can enter the feed cylinder 302 through the feed hopper 303, and then enter the extrusion cylinder 101 through the connecting pipe 301; the rotation of the drive rod 105 can drive the rotating wheel II 308 to rotate, and then drive the rotating wheel I 307 and the rotating rod II 305 to rotate through the transmission belt 309. The rotation of the rotating rod II 305 can drive the spiral plate II 306 to rotate, thereby extruding and conveying the raw materials downward; the two support plates II 304 can restrict the rotating rod II 305 to prevent the rotating rod II 305 from deviating during rotation; the baffle 310 can protect the rotating wheel I 307 and the transmission belt 309.
