Description

Technical Field

[0001] The present invention relates to the field of fertilizers, and more particularly to an environmentally friendly fertilizer and a preparation method thereof. Background Art

[0002] With the growing adoption of sustainable agricultural development, environmentally friendly fertilizers, especially organic compost, have garnered significant attention due to their potential to improve soil structure, reduce environmental pollution, and increase fertilizer utilization. Currently, organic fertilizer composting methods primarily include traditional natural composting and mechanized composting. Traditional natural composting typically utilizes static composting, where raw materials are simply piled and then sealed for fermentation. This composting method relies on natural diffusion to obtain oxygen, making uniform ventilation difficult. Inadequate internal ventilation limits microbial activity and makes anaerobic fermentation more likely to occur, producing pungent, foul-smelling gases such as hydrogen sulfide, which pollutes the environment. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides an environmentally friendly fertilizer and a preparation method thereof, which has the beneficial effect of facilitating ventilation during composting.

[0004] An environmentally friendly fertilizer preparation device includes a compost box. A recessed portion is provided in the middle of the compost box. The cross section of the recessed portion is an isosceles triangle. Multiple strip holes are distributed on the side arms of the recessed portion. A support leg is fixed to each of the four corners of the lower side of the compost box.

[0005] The right side of the compost box is detachably connected with a side plate via bolts.

[0006] A base is fixed on the left side of the compost box, and two motors are fixed on the base. Vertical shafts are fixed on the output shafts of the two motors, and each vertical shaft is axially provided with an axial edge. Two rotating seats are respectively vertically slidably connected to the two vertical shafts, and V-shaped walls are fixed on the two rotating seats, and a plug plate is provided on the lower side of each V-shaped wall.

[0007] A method for preparing an environmentally friendly fertilizer comprises the following steps:

[0008] S1: Chop the straw into small pieces and adjust the feces until they can be held in a ball without falling apart and water can be seen between the fingers without dripping;

[0009] S2: Place a layer of straw in the compost box, then a layer of feces, and then a layer of wood ash, stacking layer by layer, with no limit on height;

[0010] S3: Separate the fertilizer pile from top to bottom through two inserts in the middle of the fertilizer pile to promote oxygen supply and uniform fermentation;

[0011] S4: The material is dark brown, odorless, with a musty smell, and the straw is brittle, which means it has reached the composting standard.

[0012] The invention discloses an environmentally friendly fertilizer, which is composed of the following raw materials in parts by weight: 5 parts of straw, 3 parts of feces, and 5 parts of wood ash. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 4-5 As shown;

[0028] Since the environmentally friendly fertilizer preparation device includes a compost box 101, a recessed portion 105 is provided in the middle of the compost box 101, the cross-section of the recessed portion 105 is an isosceles triangle, and a plurality of strip holes 104 are evenly distributed on the side arms of the recessed portion 105. A support leg 102 is welded at the four corners of the lower side of the compost box 101, and the compost box 101 is supported by the four support legs 102. Environmentally friendly fertilizer composed of straw, feces, and wood ash is poured onto the compost box 101, and the bottom of the fertilizer enters the recessed portion 105. Since the recessed portion 105 is provided with a plurality of strip holes 104, air can enter the bottom of the fertilizer from the plurality of strip holes 104, which facilitates ventilation during composting, maintains the activity of microorganisms during fermentation, and produces higher quality environmentally friendly fertilizer.

[0029] In practical application, for example, a small farm produces approximately 50 kg of straw and 30 kg of manure daily. These materials are mixed with an appropriate amount of wood ash and spread flat on a compost box 101. The 20 cm support height of the legs 102 creates ample ventilation space between the bottom of the compost box 101 and the ground. Combined with the slatted holes 104 in the recessed portion 105, air can enter the compost pile from both the bottom and the sides. In the initial stages of composting, microbial decomposition of organic matter releases a significant amount of heat. The slatted holes 104 allow for the timely discharge of hot and humid gases, preventing excessive temperatures within the compost pile from inhibiting microbial activity.

[0030] In addition, to further optimize the ventilation effect, a micro fan can be installed at the bottom of the compost box 101. When the oxygen content in the compost is detected to be lower than 15%, the fan automatically starts and forces air to the bottom of the compost through the strip holes 104.

[0031] Meanwhile, the design of the recessed portion 105 also helps to collect the leachate produced in the composting process. Below the compost box 101, a collecting bucket is placed, and the leachate flows into the bucket through the strip holes 104 and can be used as liquid fertilizer after simple treatment.

[0032] like Figure 4-5 As shown;

[0033] Because the right side of the compost box 101 is detachably connected with the side plate 103 by bolts, after the side plate 103 is unloaded, the fermented fertilizer can be discharged from one side of the compost box 101, which is convenient for discharging the piled fertilizer.

[0034] like Figure 4-7 As shown;

[0035] Since the left side of the compost box 101 is connected to the base 201 by bolts, the base 201 is connected to two motors 1 202 by screws, the output shafts of the two motors 1 202 are connected to the vertical shaft 204 through a coupling, and each vertical shaft 204 is axially provided with an axial ridge 203, and the two swivel seats 308 are respectively vertically slidably connected to the two vertical shafts 204, and the two swivel seats 308 are welded with V-shaped walls 301, and the lower side of each V-shaped wall 301 is provided with a plug plate 305. When the fertilizer is piled too high on the compost box 101, the middle part of the compost pile needs to be ventilated, so the two swivel seats 308 are respectively slid vertically on the two vertical shafts 204 to adjust the height of the two V-shaped walls 301 and the two swivel seats 308. The two motors 1 202 respectively drive the two vertical shafts 204 to rotate, and then through the two axial The edges 203 drive the two rotating seats 308 to rotate respectively, and finally drive the two inserting plates 305 and the two V-shaped walls 301 to rotate, so that the two inserting plates 305 and the two V-shaped walls 301 are rotated to open or close. The two inserting plates 305 and the two V-shaped walls 301 are initially in an open state. The two inserting plates 305 and the two V-shaped walls 301 are moved to a suitable height so that the two inserting plates 305 and the two V-shaped walls 301 are rotated close to each other, so that the two inserting plates 305 are inserted into the fertilizer pile, thereby dividing the fertilizer pile into two parts, the upper and lower parts, and the two V-shaped walls 301 prevent the fertilizer from scattering on the two inserting plates 305. Then, the two inserting plates 305 are driven to rise, so that the upper and lower parts of the fertilizer pile are separated, so that air can enter the middle of the waste pile, helping the fertilizer piled too high to be better ventilated, and producing better quality environmentally friendly fertilizer.

[0036] Furthermore, a hollow channel is opened inside the V-shaped wall 301 and connected to the inner side of the V-shaped wall 301, so as to facilitate the passage of the microbial agent liquid into the fertilizer, thereby allowing the fertilizer to ferment quickly.

[0037] Furthermore, an annular gas collecting hood is provided around the compost box 101 and connected to an activated carbon-biofilter purification device to filter the waste gas generated by the fermentation, so that the gas discharged by the fermentation is cleaner.

[0038] like Figure 4-8 As shown;

[0039] Since the base 201 is welded with a vertical pole 401, the lifting seat 206 is vertically slidably connected to the vertical pole 401, and a telescopic rod 207 is connected to the base 201 by bolts. The end of the telescopic rod 207 is connected to the lifting seat 206 by bolts. Two parallel rods 205 are welded to the right end of the lifting seat 206, and the left parts of the two rotating seats 308 are inserted between the two parallel rods 205. The telescopic rod 207 can be extended and retracted to drive the lifting seat 206 to rise and fall and slide on the vertical pole 401, thereby driving the two parallel rods 205 to rise and fall and slide. When the two parallel rods 205 rise and fall and slide, the two rotating seats 308 can be driven to rise and fall without affecting the horizontal rotation of the two rotating seats 308, thereby driving the two inserting plates 305 and the two V-shaped walls 301 to rise and fall, thereby facilitating the lifting of the fertilizer pile separated up and down.

[0040] like Figure 6-7 As shown;

[0041] Since two flat rods 304 are welded to the outside of each of the V-shaped walls 301, two protrusions 302 are welded to the upper side of the inserting plate 305, and the two protrusions 302 are respectively slidably connected to the two flat rods 304. The flat rods 304 are connected to the telescopic rod 2 303 by bolts, and the movable end of the telescopic rod 2 303 is connected to the protrusion 302 by bolts. The telescopic rod 2 303 can be extended and retracted to drive the flat rod 304 to slide on the protrusion 302, thereby driving the inserting plate 305 to slide back and forth relative to the V-shaped wall 301. When it is necessary to pour the fertilizer pile separated in the upper half back into the compost box 101, the two inserting plates 305 are driven to move outward relative to the two V-shaped walls 301, and the two inserting plates 305 are moved away from each other, so that the fertilizer on the two inserting plates 305 falls back into the compost box 101.

[0042] like Figure 6-7 As shown;

[0043] Since the two inserting plates 305 are provided with cutting edges 306 at opposite ends, and multiple through holes 307 are evenly distributed on the inserting plates 305, the cutting edges 306 facilitate the two inserting plates 305 to be easily inserted into the fertilizer pile, and the multiple through holes 307 allow the upper half of the separated fertilizer pile to be better ventilated, which is conducive to the fermentation of the upper half of the separated fertilizer pile.

[0044] like Figure 6-8 As shown;

[0045] Since a circular ring 501 is provided above the two V-shaped walls 301, a plurality of stirring rods 508 are evenly distributed in a ring shape on the lower side of the circular ring 501, a plurality of bottom rods 506 are fixed on the plurality of stirring rods 508, a crossbeam 502 is fixed on the upper side of the circular ring 501, a vertical shaft 504 is vertically slidably connected to the middle of the crossbeam 502, two discs 507 are fixed to the lower part of the vertical shaft 504, the two discs 507 are respectively located on both sides of the crossbeam 502, two compression springs are sleeved on the lower part of the vertical shaft 504, the two compression springs are located between the two discs 507, the two compression springs are respectively located on both sides of the crossbeam 502, and one of the discs 507 is fixed on There is an L-shaped rod 503, which is vertically slidably connected to the crossbeam 502. The vertical shaft 504 can rotate with its own axis as the axis, thereby driving the crossbeam 502, the ring 501, multiple stirring rods 508 and multiple bottom rods 506 to rotate. When the vertical shaft 504 is raised or lowered, it drives the crossbeam 502, the ring 501, multiple stirring rods 508 and multiple bottom rods 506 to rise or fall, and then the multiple stirring rods 508 and multiple bottom rods 506 can be lowered into the fertilizer in the compost box 101, and then the multiple stirring rods 508 are driven to rotate to stir the fertilizer, and the multiple bottom rods 506 are raised or lowered to perform rotational turning of the fertilizer, which is more conducive to air entering the fertilizer. When turning the compost, the two insert plates 305 are moved away from each other, and the two V-shaped walls 301 are respectively blocked on the front and rear sides of the compost box 101 to prevent the fertilizer from splashing when turning the compost. The vertical shaft 504 can also move left and right to drive the crossbeam 502, the ring 501, the multiple stirring rods 508, and the multiple bottom rods 506 to move left and right, turning the fertilizer at different left and right positions. The crossbeam 502 can rise and fall relative to the L-shaped rod 503 and the vertical shaft 504, thereby compressing one of the compression springs. The two compression springs help the crossbeam 502 return to its original position, causing the crossbeam 502 to oscillate up and down, thereby causing the ring 501, the bottom rod 506, and the stirring rod 508 to oscillate up and down via the two compression springs. This oscillation is more effective in turning the compost and allows oxygen to enter the compost.

[0046] Furthermore, the upper part of the fertilizer pile can be lifted up using two insert plates 305, and then the upper part of the fertilizer pile can be turned over in a small area, which makes the turning more targeted.

[0047] Furthermore, when processing chicken manure with a moisture content of up to 75%, the biggest challenge is that the material easily adheres to the compost turning equipment, resulting in reduced turning efficiency. To address this issue, the surface of the stirring rod is specially designed with serrated protrusions. When the stirring assembly is inserted into the sticky pile of chicken manure, the vertical shaft rotates at a low speed of 15 rpm, while the compression spring produces small oscillations. The serrated protrusions act like miniature scrapers, continuously peeling off the adhering chicken manure during rotation, and the oscillating motion further shakes off any material remaining on the rod.

[0048] When the compost is nearly mature, dark brown in color, and odorless, and ready for a final turning and discharge, the mixing assembly switches to "gentle mode," slowly rotating the vertical axis at 5 rpm and adjusting the compression spring's oscillation amplitude to 2 cm to prevent excessive crushing of the already decomposed material. Simultaneously, two V-shaped walls move to either side of the pile to form a barrier, funneling the compost toward the center for subsequent unified discharge via removable side panels.

[0049] like Figure 8 As shown;

[0050] Since the upper part of the vertical pole 401 is vertically slidably connected to the left part of the hollow rod 403, the upper part of the vertical pole 401 is fixed with a motor 2 404, the output shaft of the motor 2 404 is fixed with a screw rod 402, the hollow rod 403 is provided with a nut that cooperates with the screw rod 402, the screw rod 402 cooperates with the nut, the right end of the hollow rod 403 is horizontally slidably connected with the solid rod 406, the two ends of the telescopic rod 3 405 are respectively connected to the hollow rod 403 and the solid rod 406, the right end of the solid rod 406 is fixed with a motor 3 505, and the output shaft of the motor 3 505 is connected to the upper end of the vertical shaft 504 through a coupling. Motor 2 404 drives the screw rod 402 to rotate, thereby driving the hollow rod 403 to rise and fall on the vertical rod 401. When the telescopic rod 3 405 is extended or retracted, it can drive the solid rod 406 to slide left and right on the hollow rod 403, thereby driving the motor 3 505 to move up and down and left and right. The motor 3 505 can drive the vertical shaft 504 to rotate, thereby driving the ring 501, the crossbeam 502, the bottom rod 506 and the stirring rod 508 to move up and down and left and right, as well as to rotate, so that the bottom rod 506 and the stirring rod 508 perform the turning operation.

[0052] S1: Chop the straw into small pieces and adjust the feces until they can be held in a ball without falling apart and water can be seen between the fingers without dripping;

[0053] S2: Place a layer of straw in the compost box 101, a layer of feces on top, and then a layer of wood ash, stacking layer by layer, with no limit on the height;
