[0002] With the growth of the population and the development of the economy, the generation amount of solid organic waste is increasing continuously. If organic wastes such as plant straws, pig, cattle and sheep feces, fruit and vegetable wastes in vegetable markets, and human and animal feces in rural areas are not properly treated, they will not only cause serious pollution to the environment, but also waste a large amount of resources;

[0003] At present, the solid organic waste composting equipment on the market generally has the problem of poor efficiency. The stirring mechanisms of many composting devices are not reasonably designed, and the full mixing of organic wastes cannot be achieved. It is often difficult for existing equipment to achieve uniform addition of medicaments. Some equipment uses a simple spraying method, and the medicament distribution is uneven, which is likely to cause the situation of excessive medicaments in some areas and insufficient medicaments in some areas, affecting the quality and efficiency of composting.

[0004] Therefore, we make improvements in this regard and propose a solid organic waste composting device and a composting method thereof. Summary of the Invention

[0039] To enable those skilled in the art to better understand the solution of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0040] As described in the background art, the medicament and the stirring in the composting device are uneven, and the organic waste is unevenly mixed, which is not conducive to the composting efficiency.

[0041] To solve this technical problem, the present invention provides a solid organic waste composting device and its composting method, which are applied to stirring composting.

[0042] Specifically, please refer to Figures 1 - 8 , the solid organic waste composting device includes a composting tank 1 and a feeding port 2 and a discharge pipe 3 that are staggered and distributed on the composting tank 1. A composting component 4 is provided on the composting tank 1. The composting component 4 includes a stirring mechanism 40 and a composting mechanism 41. The stirring mechanism 40 includes a stirring motor 401, a stirring central rod 402, and a central gear 403. The stirring motor 401 is installed on the composting tank 1 and its output end is connected to the stirring central rod 402. The central gear 403 is installed on the stirring central rod 402. A plurality of driven gears 404 are engaged with the central gear 403, and a stirring driven rod 405 is installed on the driven gear 404

[0043] The feeding port 2 includes a support frame 201 and a magnetic attraction rod 202. The support frame 201 is connected to the feeding port 2, and a plurality of magnetic attraction rods 202 are connected to the support frame 201.

[0044] When the stirring motor 401 is started, it drives the stirring central rod 402 to rotate, thereby causing the central gear 403 to rotate, driving the driven gear 404 and the stirring driven rod 405 to rotate together, and stirring the organic waste in the composting tank 1. The support frame 201 in the feeding port 2 is connected to the feeding port 2, and a plurality of magnetic attraction rods 202 are connected to the support frame 201. During the input process of the organic waste, the magnetic attraction rods 202 can adsorb the metal impurities therein to prevent the metal impurities from having an adverse effect on the composting process. During the composting process, the organic waste is input into the composting tank 1 from the feeding port 2. The stirring mechanism 40 continuously stirs to fully mix the organic waste, and at the same time promotes the contact between the microorganisms and the organic waste. The composted organic fertilizer can be discharged from the composting tank 1 through the discharge pipe 3.

[0045] A solid organic waste composting device provided by the present invention drives a stirring central rod 402, a central gear 403, a driven gear 404, and a stirring driven rod 405 to work together through a stirring motor 401, so as to realize efficient stirring of organic waste. A magnetic attraction rod 202 can adsorb metal impurities in the organic waste when it is put in, ensuring the purity of the composting process, avoiding interference of metal impurities on the growth and composting process of microorganisms, and achieving the effect of improving the composting efficiency.

[0046] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0049] Embodiment 1:

[0050] Please refer to Figures 1 - 7, a solid organic waste composting device, whose composting mechanism 41 includes a micro water pump 410, a rotating disk 411 and a battery 412. A plurality of micro water pumps 410 are respectively connected to the stirring central rod 402 and the stirring driven rod 405. A liquid storage tank is provided on the composting box 1. The input end of the micro water pump 410 communicates with the liquid storage tank and the output end communicates with the stirring central rod 402 and the stirring driven rod 405. The rotating disk 411 is connected to the composting box 1 and installed with the battery 412. A plurality of mounting pipes 414 are alternately installed on both the stirring central rod 402 and the stirring driven rod 405. Pulse spray nozzles 415 are communicated with the mounting pipes 414. Stirring plates 416 are installed at the free ends of the mounting pipes 414. A shunt hollow plate 417 is connected to the stirring plates 416; the liquid storage tank on the composting box 1 is used to store agents such as microbial rapid corrosion agents. The input end of the micro water pump 410 communicates with the liquid storage tank, extracts the agent, and the output end communicates with the stirring central rod 402 and the stirring driven rod 405, so that the agent can be transported to various positions through the channels inside the stirring central rod 402 and the stirring driven rod 405. When the stirring central rod 402 and the stirring driven rod 405 rotate, they drive a plurality of mounting pipes 414 installed thereon to move together. The pulse spray nozzles 415 communicated with the mounting pipes 414 spray the agent in the form of pulses at the right time, making full contact with the organic waste in the composting box 1. The stirring plates 416 and the shunt hollow plate 417 further promote the mixing of the agent and the organic waste during the stirring process, improving the composting effect. The rotating disk 411 is connected to the composting box 1 and can drive the battery 412 to rotate to avoid circuit entanglement, thereby providing power support for the entire composting mechanism 41. Under the combined action of stirring and the agent, the organic matter in the organic waste is decomposed by microorganisms and gradually composted, achieving the effect of the coordination of stirring and the agent, and thus improving the overall composting efficiency and quality.

[0051] Through the mutual cooperation of the provided micro water pump 410 with the pulse spray nozzles 415, the stirring plates 416 and the shunt hollow plate 417, the reasonable use of the agent in the composting process is ensured. The pulse spray nozzles 415 spray the agent in the form of pulses, enabling the agent to be more evenly distributed in the organic waste, and thus achieving the effect of the coordination of stirring and the agent.

[0052] Embodiment 2:

[0053] Please refer to Figures 5 - 8, A solid organic waste composting device, on which a protection mechanism 42 is provided on the installation pipe 414. The installation pipe 414, the stirring central rod 402, and the stirring driven rod 405 achieve the protection effect through the protection mechanism 42. The protection mechanism 42 includes a protection vertical plate 420, a protection block 421, and a protection baffle 422. The protection vertical plate 420 is connected to the installation pipe 414. The protection block 421 and the protection baffle 422 are both installed on the installation pipe 414. An arc-shaped groove is provided at the center of the protection block 421, and at least four diversion grooves communicating with the arc-shaped groove are also provided on the protection block 421. A telescopic rod 423 connected to the stirring plate 416 is installed on the protection baffle 422, and a spring 424 is installed on the telescopic rod 423; when the pulse spray head 415 does not spray the medicament, the protection block 421 is in the initial position, closely surrounding the pulse spray head 415. The protection vertical plate 420, the protection baffle 422, and the protection block 421 together form a protection system, effectively blocking various impurities and particles in the organic waste from approaching the pulse spray head 415. The arc-shaped groove and the diversion grooves at the center of the protection block 421 further enhance the guiding and dispersing effects on the tiny particles and fluids that may approach the pulse spray head 415, preventing them from accumulating near the spray head and causing blockage. When the pulse spray head 415 starts to spray the medicament, the spraying force acts on the protection block 421. Since an arc-shaped groove is provided at the center of the protection block 421, the medicament can impact a specific position of the protection block 421 more concentratedly, thus more effectively pushing the protection block 421 to unfold. As the protection block 421 unfolds, at least four diversion grooves will correspondingly change the flow direction of the fluid, enabling the medicament to be sprayed more smoothly and at the same time preventing the impurities pushed away from approaching the pulse spray head 415 again. The protection baffle 422 is connected to the stirring plate 416 through the telescopic rod 423. During the unfolding process of the protection block 421, the telescopic rod 423 will be adjusted in length as needed, and the spring 424 plays a role in buffering and assisting in resetting.

[0054] By setting the protection block 421 to cooperate with the telescopic rod 423 and the stirring plate 416, the pulse spray head 415 can be protected in the non-spraying state, greatly reducing the risk of blockage of the pulse spray head 415. The diversion grooves guide the flow direction of the medicament when the pulse spray head 415 sprays, which helps the medicament to be more evenly distributed in the organic waste.

[0055] A solid organic waste composting device is further optimized. Specifically, as Figure 2As shown, the central gear 403 and the driven gear 404 are both located in the liquid storage tank. The stirring central rod 402 is provided with a liquid inlet groove communicating with the liquid storage tank. When the stirring central rod 402 rotates, the medicament in the liquid storage tank can enter the channel inside the stirring central rod 402 through the liquid inlet groove. In this way, the medicament can be conveyed out as the stirring central rod 402 rotates to the installation pipe 414 and the pulse nozzle 415 on the stirring driven rod 405, realizing the spraying of the medicament on the organic waste.

[0056] Through the liquid inlet groove, the liquid inlet groove on the stirring central rod 402 communicates with the liquid storage tank, ensuring that the medicament can smoothly enter the inside of the stirring central rod 402 and realizing the efficient conveyance of the medicament.

[0057] Furthermore, as Figure 2 and Figure 3 shown, the micro water pump 410 and the power supply battery 412 are connected by a power cord, and the rotating disk 411 is connected to the power cord. During the startup process of the stirring motor 401, the rotating disk 411 can cooperate with the power supply battery 412 to electrically connect the micro water pump 410. The rotating disk 411 rotates on the composting bin 1, which can avoid the winding of the power cord.

[0058] By setting the rotating disk 411, it can avoid the situation of the power cord winding when the power supply battery 412 supplies power to the micro water pump 410.

[0062] S3. When the decomposition reaches a certain stage, use the equipment to raise the temperature to above 70 degrees and maintain it for 1 hour.

During the entire decomposition process, control the moisture content of the organic waste between 50%-65% through the equipment to meet the growth and metabolic needs of microorganisms.

[0063] S4. After a three-hour composting process, the conversion of organic waste into organic fertilizer is completed, and stable organic fertilizer is obtained.
