Description

Technical Field

[0002] Composting is the process of converting organic waste, such as plant residues, kitchen waste, and animal manure, into nutrient-rich organic fertilizer through natural fermentation and decomposition. This process requires the help of a composting device, which can help accelerate the composting process of organic waste and improve the efficiency of natural fermentation and decomposition. However, most of the existing composting devices can achieve aerobic composting effects, but these devices make it difficult for oxygen to reach different distribution areas of organic waste for sufficient contact reaction during the aerobic composting process, and cannot achieve automatic adjustment and control of the overall humidity of organic waste during aerobic fermentation and decomposition. As a result, the humidity of the organic waste compost is difficult to maintain at the expected stable level, causing compost moisture imbalance or loss, reducing the quality and decomposition efficiency of the aerobic composting of organic waste, making it difficult for the generated compost fertilizer to promote high-quality plant growth, and therefore cannot meet the demand for fertilizer use.

[0030] Example

[0031] like Figure 1-4 As shown, the present application provides an automatic composting device, which includes a frame 1.

[0032] A rotating motor 2 is provided on the frame 1. The output end of the rotating motor 2 is connected to a small transmission gear 3 through a flat key. The small transmission gear 3 is surrounded by one end of a transmission belt 4. The other end of the transmission belt 4 is surrounded by teeth on the outside of a large transmission gear 5. The large transmission gear 5 is mounted on a rotating shaft 6. The rotating shaft 6 passes through a composting reaction chamber 7, and the two ends of the rotating shaft 6 are respectively connected to two sides of the composting reaction chamber 7, so that the large transmission gear 5 can drive the rotating shaft 6 to rotate in the composting reaction chamber 7.

[0033] A sealing cover plate 8 is connected to the composting reaction chamber 7 via a hinge. A spray mechanism is installed at the bottom of the sealing cover plate 8. The spray mechanism includes two symmetrically arranged groove-shaped workpieces 9. Two guide rods 10 are arranged between the two groove-shaped workpieces 9, and a threaded rod 11 is connected between the two groove-shaped workpieces 9.

[0034] Furthermore, in a preferred embodiment of the present invention, a plurality of stirring bars 12 are provided on the rotating shaft 6 , and a stirring blade 13 is provided at the top of each stirring bar 12 .

[0035] Furthermore, in a preferred embodiment of the present invention, an annular threaded nut 14 is installed on the threaded rod 11 .

[0036] Furthermore, in a preferred embodiment of the present invention, a guide slider 15 is provided on each side of the annular threaded nut 14 .

[0037] Furthermore, in a preferred embodiment of the present invention, each of the guide sliders 15 is connected to two guide rods 10 in the middle of the groove-shaped workpiece 9 .

[0038] Furthermore, in a preferred embodiment of the present invention, a first servo motor 16 is fixed to the bottom end of the annular threaded nut 14 , and a rotating disk 17 is provided at the output end of the first servo motor 16 .

[0039] Furthermore, in a preferred embodiment of the present invention, the bottom of the rotating disc 17 is fixed to the upper end of the first servo motor 16 so that the first servo motor 16 can drive the rotating disc 17 to rotate when it operates relative to the annular threaded nut 14 .

[0040] Furthermore, in a preferred embodiment of the present invention, a plurality of sprinkler heads 18 are provided at the bottom of the rotating disc 17 , and the plurality of sprinkler heads 18 surround the first servo motor 16 , and each sprinkler head 18 is connected to a water supply hose.

[0041] Furthermore, in a preferred embodiment of the present invention, one end of the threaded rod 11 is connected to the second servo motor 19 via a coupling.

[0042] Furthermore, in a preferred embodiment of the present invention, an oxygen tank 20 is placed on the side of the frame 1, and the oxygen tank 20 is connected to the inside of the composting reaction chamber 7 through an air pipe 21. The oxygen tank 20 is used to provide the oxygen required for the composting process in the composting reaction chamber 7.

[0043] It should be noted that organic waste such as plant residues, kitchen waste and animal feces are poured into the composting reaction chamber for natural fermentation and decomposition reaction. During the natural fermentation and decomposition reaction, the vent valve of the oxygen tank 20 is opened according to the preset optimal aeration time node, so that an appropriate amount of oxygen in the oxygen tank 20 is controlled to be introduced into the composting reaction chamber 7 through the gas pipe 21. The appropriate amount of oxygen introduced can contact and react with the organic waste to achieve an aerobic composting effect, which helps to better accelerate the decomposition and composting of the organic waste. During the process of oxygen tank 20 introducing oxygen into organic waste, the rotary motor 2 is controlled to start, and the output end of the rotary motor 2 causes the small transmission gear 3 to rotate, so that the small transmission gear 3 can drive the large transmission gear 5 to rotate synchronously through the transmission belt 4. At this time, the rotating large transmission gear 5 causes the rotating shaft 6 to rotate in the compost reaction chamber 7. When the rotating shaft 6 rotates, the stirring bar 12 on it will fully stir the mixed and decomposed organic waste, and the stirring blade 13 at the top of the stirring bar 12 will continuously turn the organic waste, so that the introduced oxygen can fully contact and react with various areas of the organic waste, thereby achieving the effect of regularly turning the compost pile to fully react with the oxygen, effectively promoting the uniform distribution of oxygen on the organic waste, accelerating its aerobic decomposition process, and improving the composting efficiency and compost decomposition quality.

[0044] It should be noted that, in the process of turning the organic waste compost pile, the first servo motor 16 is controlled to rotate forward and reverse regularly. Since the output end of the first servo motor 16 is fixed to the bottom of the annular threaded nut 14, the first servo motor 16 realizes forward and reverse autonomous reciprocating rotation during operation, and the rotating disc 17 is fixed to the upper end of the first servo motor 16. Therefore, when the first servo motor 16 rotates, it will drive the rotating disc 17 to rotate forward and reverse synchronously. At this time, the water pump is started to allow water to enter the sprinkler nozzle 18 through the water hose, and then the water source is atomized downward by the high pressure effect of the sprinkler nozzle 18. Spraying, thereby being able to regularly perform local moisturizing spraying on the organic waste compost pile that is being stirred and turned below, thereby achieving the local humidity adjustment effect of automatic composting. The ideal humidity should be maintained in the range of 50% to 60% to ensure the distribution stability of the compost humidity and avoid the imbalance or loss of water in the decomposition of the organic waste compost, which may lead to excessive drying of the compost fertilizer; at the same time, the regular forward and reverse rotation of the first servo motor 16 can prevent the water supply hoses of each sprinkler head 18 from tangling and entanglement, making the spraying mechanism operate more reasonably, thereby reducing the probability of failure of the spraying mechanism.

[0045] It should be noted that when the second servo motor 19 is started to drive the threaded rod 11 to rotate, the rotation of the threaded rod 11 on the two grooved workpieces 9 will drive the annular threaded nut 14 to translate on the threaded rod 11, so that the annular threaded nut 14 can drive the rotating disc 17 to perform controllable reciprocating translation sliding at the bottom of the sealing cover plate 8, so that the multiple sprinkler nozzles 18 rotate and spray while performing translational spraying and atomizing watering on the organic waste in the natural fermentation in the composting reaction chamber 7, thereby achieving a globally controllable compost moisturizing spraying effect, optimizing the uniformity and rationality of humidity regulation during the organic waste and aerobic fermentation reaction process, and improving the efficiency and quality of natural fermentation and decomposition of organic waste, so that the generated compost fertilizer can greatly improve the planting quality of soil and crops, promote plant growth, and enhance the sufficient aerobic reaction between oxygen and microorganisms in organic waste to promote the activity of aerobic microorganisms and accelerate the decomposition rate of organic matter; compared with traditional composting devices, this device greatly improves the intelligence and automation level of aerobic composting.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
