Description

Technical Field

[0001] The present invention relates to the technical field of composting, in particular to composting processing equipment for processing organic fertilizers. Background Art

[0002] In the field of modern agriculture and environmental governance, composting technology is a key means to achieve resource utilization of organic waste. Its efficiency and quality are directly related to waste reduction, harmless treatment and subsequent application of organic fertilizers. In order to promote the decomposition process of compost materials, appropriate oxygen content and temperature distribution must be maintained inside the pile, which requires composting equipment to have efficient ventilation and stirring functions.

[0003] In the prior art, composting equipment usually introduces gas (such as air, oxygen, etc.) into the compost body through a separate ventilation device to meet the aerobic metabolism needs of microorganisms. At the same time, the compost material is turned and stirred with the help of a stirring mechanism to break up the material lumps and promote heat transfer and material exchange. However, this "separation of ventilation and stirring" design has significant defects: on the one hand, the stirring mechanism mostly adopts traditional structures such as spiral blades and stirring paddles, and its core function is limited to the mechanical turning of the material, making it difficult to achieve directional gas injection simultaneously during the stirring process. On the other hand, a separate ventilation device (such as buried pipe ventilation, bottom aeration, etc.) can often only transport gas to specific areas of the pile, and the diffusion of gas in the gaps between the materials is greatly affected by factors such as material compactness and particle size, which can easily lead to local hypoxia or uneven ventilation.

[0004] The above problems directly lead to a small contact area between the composting material and the gas and low contact efficiency. During stirring, the violent movement of the material may destroy the ventilation path, causing gas to escape. During ventilation, the static material will hinder the uniform penetration of the gas. This uncoordinated working mode will not only prolong the composting cycle, but may also cause the emission of malodorous gases (such as hydrogen sulfide and ammonia) due to the local anaerobic environment, reduce the quality of the compost product, and seriously affect the overall composting effect. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a composting equipment for organic fertilizer processing to solve the technical problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a composting device for processing organic fertilizer, comprising a composting mechanism, a stirring mechanism, and an air jet mechanism, wherein the composting mechanism is equipped with a stirring mechanism, and the stirring mechanism is equipped with multiple sets of air jet mechanisms;

[0007] The stirring mechanism includes a stirring hollow rod, which is rotatably installed in the composting mechanism, and a spiral blade is fixed on the outside of the stirring hollow rod, and the diameter of the spiral blade gradually increases from bottom to top;

[0008] A fixed rod is arranged inside the mixing hollow rod and is provided with multiple sets of fixed cams;

[0009] The jet mechanism includes a jet connecting pipe, which is connected to the inner cavity of the stirring hollow rod, and the jet connecting pipe is provided with an end exhaust hole and a waist exhaust hole;

[0010] The plugging head and the plugging ring are movably arranged inside the air jet connecting pipe, and the plugging head and the plugging ring are connected by a telescopic rod, and a spring is sleeved on the telescopic rod;

[0011] The four corners of the plugging head and the plugging ring are fixedly connected by connecting rods. When the plugging head contracts axially, the connecting rods synchronously drive the plugging ring to expand and contract axially, thereby opening the end exhaust holes and the waist exhaust holes.

[0012] The fixed ball is fixed to the end of the telescopic rod and cooperates with the fixed cam. The fixed ball and the telescopic rod are welded to each other to ensure the overall strength and service life;

[0013] When the spiral blades rotate with the mixing hollow rod, the small-diameter blades at the bottom lift the deep-layer materials, and the large-diameter blades at the top scatter the materials. At the same time, the jet mechanism rotates with the mixing hollow rod, and the fixed cam and spring open and close the exhaust hole to inject gas.

[0014] As can be seen from the above, the diameter of the spiral blades increases from small to large from bottom to top. The small-diameter blades at the bottom can generate strong thrust, "lifting" the dense materials deep in the compost bin, especially the easily compacted areas at the bottom, breaking the local retention caused by material sedimentation. The large-diameter blades at the top scatter the lifted materials at a high position, forming a "bottom-to-top" full-compost cycle, ensuring that the materials are evenly heated and exposed to the gas, avoiding the disadvantage of traditional agitators that only stir the surface materials. The reinforcement plate strengthens the connection between the blade and the hollow stirring rod, which can withstand the resistance of high-viscosity materials without deformation. The fixed rod cooperates with the positioning mechanism to ensure stable cam linkage during the mixing process, improving the durability of the equipment.

[0015] The stirring mechanism also includes a reinforcing sheet, which is arranged between the spiral blade and the stirring hollow rod to strengthen the strength of the spiral blade;

[0016] The snap-fit ​​seat is fixedly arranged at the bottom of the fixing rod, and the snap-fit ​​seat is fixedly connected to the base, and is used to fix the fixing rod and the multiple sets of fixed cams;

[0017] The composting mechanism includes a compost barrel and a base. The compost barrel is installed on the base, and a closable top cover is provided on the top of the compost barrel, and a hanging ring is provided on the top cover.

[0018] As can be seen from the above, the composting mechanism achieves the unity of sealing and discharging convenience during the composting process through the coordinated design of the composting barrel, base and discharging mechanism. The composting barrel and the sealing gasket of the top cover cooperate to effectively isolate the malodorous gases generated during the composting process, such as hydrogen sulfide and ammonia, and reduce pollution to the surrounding environment. The base provides stable support for the entire equipment to prevent violent vibrations during stirring from affecting the structural stability. The sliding design of the discharging mechanism is particularly critical. The discharging door can be easily opened and closed by sliding the slider and the chute. The sliding closing plate cooperates with the closed chute, which completely solves the problems of leakage and jamming of the traditional discharging port, and increases the collection efficiency of decomposed manure by more than 30%. At the same time, it reduces the cost of manual cleaning, making it suitable for large-scale continuous production scenarios.

[0019] The stirring mechanism also includes a first air inlet cylinder, a second air inlet cylinder and a connecting pipe. The first air inlet cylinder is located at the bottom of the stirring hollow rod and is connected to the interior thereof. The second air inlet cylinder is slidably connected to the first air inlet cylinder, and one side of the second air inlet cylinder is fixedly connected to the connecting pipe.

[0020] The jet mechanism solves the problem of uneven gas distribution in traditional fixed ventilation devices through the design of dynamically opening and closing exhaust holes. The end exhaust holes and waist exhaust holes of the jet connecting pipe open and close intermittently under the action of a fixed cam and a spring. When the jet mechanism rotates with the hollow stirring rod, the fixed ball rolls along the cam. Under the action of the spring, the telescopic rod contracts and drives the sealing head and sealing ring to move, so that the end exhaust holes and waist exhaust holes open when the material is turned over, and the air is precisely injected into the gaps between loose materials. This design avoids the problem of gas diffusion being hindered in dense materials, while reducing gas escape during static conditions, so that the oxygen content of the pile is uniformly maintained at 15% to 20%, promoting the activity of aerobic microorganisms, shortening the composting cycle by 40%, and reducing the emission of malodorous gases caused by anaerobic environments.

[0021] In general, the air jet connecting pipe realizes the intermittent opening and closing of the end exhaust holes and the waist exhaust holes under the action of the spring through the cooperation of the fixed ball and the fixed cam. It rotates synchronously with the stirring to accurately spray the gas toward the tumbling material. The gas can be diffused from the exhaust holes at different heights, increasing the contact area with the material, solving the problems of uneven gas distribution and easy blockage by the material in traditional fixed ventilation devices, and improving the oxygen utilization rate.

[0022] A through hole for connecting a pipe is provided on one side of the base;

[0023] The composting mechanism also includes a discharge mechanism, which includes a discharge door arranged on one side of the compost barrel, and a slider is provided at the middle position of the top of the discharge door, and the slider is slidably matched with a slide groove on the outside of the compost barrel;

[0024] A sliding closing plate and a sliding handle. The sliding handle is provided on the discharge door and is used to control the opening and closing of the discharge door. The sliding closing plate is fixed to the top of the discharge door and is slidably connected to the compost barrel to dynamically close the chute.

[0025] The jet mechanism also includes a fixing frame. Each set of jet mechanisms has two fixing frames, one of which is fixed to the outside of the telescopic rod and fixedly connected to the jet connecting pipe, and the other is fixed to the inner wall of the jet connecting pipe. A spring is fixed between the two sets of fixing frames.

[0026] The two sets of fixing frames are both hollowed out to allow gas to pass through;

[0027] A transmission mechanism is installed on one side of the interior of the base, and the transmission mechanism is connected to the stirring mechanism. The transmission mechanism includes a transmission motor, a first transmission gear, and a second transmission gear. The transmission motor drives the first transmission gear to rotate, and the first transmission gear is engaged with the second transmission gear fixed to the outside of the first air intake cylinder.

[0028] The transmission mechanism provides a stable and controllable power output for the equipment, ensuring efficient coordination of stirring and jetting actions. The transmission motor drives the stirring hollow rod to rotate at a constant speed through the meshing of the first transmission gear and the second transmission gear, avoiding uneven stirring of the material caused by speed fluctuations. The high efficiency of the gear transmission reduces energy consumption and can adapt to different material quantities by adjusting the motor power. In addition, the sliding connection design of the first air inlet cylinder (206) and the second air inlet cylinder (207) ensures smooth air supply while transmitting power, so that the gas supply of the jet mechanism is stable and accurately matched with the stirring rhythm, avoiding the problem of disconnection of the action caused by the slippage of the traditional belt drive.

[0029] A positioning mechanism is provided at the top of the compost barrel, and the positioning mechanism includes a positioning rod fixedly connected to the compost barrel, a sleeve fixed to the top of the positioning rod and sleeved on the outside of the mixing hollow rod, and the top of the fixing rod is fixedly connected to the inside of the sleeve, which is used to provide a fixed support for the top of the fixing rod;

[0030] A sealing plug located inside the mixing hollow rod is fixed at the bottom of the sleeve to seal the top of the mixing hollow rod;

[0031] A sealing gasket is provided at the contact point between the inner wall of the compost bin and the top cover to ensure the sealing of the top cover when it is closed.

[0032] Furthermore, the transmission motor is fixed on the base, and its output shaft is connected to the first transmission gear through a key to achieve synchronous rotation.

[0033] By adopting the above technical solution, the base plays a role in stabilizing the support of the transmission motor, ensuring that the transmission motor is more stable during operation;

[0034] Specifically, the transmission motor drives the stirring hollow rod to rotate stably through gear engagement, the transmission efficiency is high and the rotating speed is controllable, which can provide sufficient power for the spiral blade to turn over heavy materials, and can also match the intermittent jet rhythm of the jet mechanism to ensure that the stirring and jetting actions are consistent, avoid power waste and improve the overall operation efficiency of the equipment.

[0035] In summary, the present application has the following advantages:

[0036] 1. The core advantage of the stirring mechanism of the present application is the gradual diameter design of the spiral blade and the stable support of the fixed rod. The diameter of the spiral blade increases from small to large from bottom to top. The small-diameter blade at the bottom can generate strong thrust to lift the dense materials in the deep part of the compost cylinder, especially the bottom area prone to compaction, to break the local retention caused by material settlement. The large-diameter blade at the top can throw the lifted materials at a high position to form a full compost body circulation of "bottom loosening-top scattering", ensuring uniform heating and gas contact of the materials, avoiding the disadvantages of traditional stirring paddles that can only stir the surface materials, and enhancing the connection strength between the blade and the stirring hollow rod, which can withstand the resistance of high-viscosity materials without deformation. The fixed rod cooperates with the positioning mechanism to ensure the stability of the cam linkage during stirring, improving the durability of the equipment.

[0037] 2. The jet mechanism of the present application solves the problem of uneven gas distribution of traditional fixed ventilation devices through the design of dynamically opening and closing exhaust holes. The end exhaust hole and the waist exhaust hole of the jet communication pipe are intermittently opened and closed under the action of the fixed cam and the spring. When the jet mechanism rotates with the stirring hollow rod, the fixed ball rolls along the cam and is contracted through the telescopic rod under the action of the spring to drive the plugging head and the plugging ring to move, so that the exhaust hole is opened when the material is stirred, and the gas is precisely sprayed into the gap between the loose materials. This design avoids the problem of gas diffusion being blocked in dense materials, reduces gas emission when stationary, maintains the oxygen content of the compost body at 15% to 20%, promotes the activity of aerobic microorganisms, shortens the composting period by 40%, and reduces the emission of malodorous gases caused by anaerobic environment.

[0038] 3. The composting mechanism of the present application realizes the unity of sealing and convenient discharging of the composting process through the cooperative design of the composting cylinder, the base and the discharging mechanism. The sealing gasket of the composting cylinder and the top cover can effectively isolate the malodorous gases such as hydrogen sulfide and ammonia generated during composting, reducing the pollution to the surrounding environment. The base provides stable support for the overall equipment, avoiding the influence of severe vibration during stirring on the structural stability. The sliding design of the discharging mechanism is particularly key. The discharging door is slidably connected with the sliding groove through the sliding block, which can easily control the opening and closing. The sliding closure plate moves with the sliding groove to completely solve the problems of material leakage and blockage of the traditional discharging port, improve the collection efficiency of the mature compost by more than 30%, reduce the labor cleaning cost, and be suitable for large-scale continuous production scenes.

[0039] 4. The transmission mechanism of the present invention provides the equipment with stable and controllable power output, ensuring efficient coordination of stirring and jetting actions. The transmission motor drives the hollow stirring rod to rotate at a constant speed through the engagement of the first transmission gear and the second transmission gear, avoiding uneven stirring of the material caused by speed fluctuations. The high efficiency of the gear transmission reduces energy consumption and can adapt to different material quantities by adjusting the motor power. In addition, the sliding connection design of the first air inlet cylinder and the second air inlet cylinder ensures unobstructed air source while transmitting power, so that the gas supply of the jet mechanism is stable and accurately matched with the stirring rhythm, avoiding the problem of disconnection of movement caused by the slippage of traditional belt transmission.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0052] like Figure 1 - Figure 9 As shown, the composting equipment provided in this embodiment realizes efficient decomposition of organic fertilizers through the coordinated design of stirring and air jetting. The specific structure is as follows:

[0053] The composting mechanism 1 comprises:

[0054] Compost bin 101: cylindrical metal bin with a capacity of 5 to 10 m 3 , installed on the base 102, with a smooth inner wall to facilitate the turning of materials;

[0055] Top cover 7: A sealing cover adapted to the top of the compost bin 101, with a sealing gasket on the edge and a fixed lifting ring 8 on the top for lifting and opening;

[0056] Discharge mechanism 5: A discharge door 501 is provided on one side of the compost barrel 101. The slider 502 slides with the chute 103 and is opened and closed by a sliding handle 504. The top sliding closing plate 503 moves with the discharge door 501, dynamically closing the chute 103 to prevent leakage.

[0057] The mixing hollow rod 201 is a hollow metal rod, which is vertically rotatably mounted in the center of the compost barrel 101 and connected to the first air inlet cylinder 206 at the bottom;

[0058] Spiral blade 202: fixed to the outside of the mixing hollow rod 201, with a diameter gradually increasing from 30cm to 60cm from bottom to top. The small diameter blade at the bottom is used to lift deep-layer materials, and the large diameter blade at the top is used to spread materials. A reinforcement plate 203 is welded between the spiral blade 202 and the mixing hollow rod 201 to improve the load-bearing capacity;

[0059] Fixed rod 204: It is inserted into the interior of the mixing hollow rod 201, and the bottom is fixed to the base 102 through the snap seat 209, and the top is connected to the positioning mechanism 6, on which multiple sets of fixed cams 205 (such as Figure 5 shown);

[0060] Air intake system: The first air intake cylinder 206 is connected to the bottom of the mixing hollow rod 201, and a second air intake cylinder 207 is slidably connected to the outside. The connecting pipe 208 is connected to the external air source such as a blower. The connecting pipe 208 passes through the through hole 104 of the base 102;

[0061] Jet Mechanism 3:

[0062] The jet connecting pipe 301: one end is connected to the inner cavity of the stirring hollow rod 201, and the other end is closed. The pipe wall is provided with an end exhaust hole 303 and a waist exhaust hole 306 (such as Figure 9 shown);

[0063] Blocking and transmission structure: The blocking head 302 is used to block the end exhaust hole 303, the blocking ring 307 is used to block the waist exhaust hole 306, the fixed ball 305 cooperates with the fixed cam 205, and the spring 310 is sleeved on the outside of the telescopic rod 304. The two ends are connected to the inner wall of the jet connecting pipe 301 and the telescopic rod 304 respectively through the hollow fixing frame 309 to allow gas to flow;

[0064] Linkage design: The plugging head 302 and the plugging ring 307 move synchronously through the four-corner connecting rods 308 to ensure that the two exhaust holes open and close at the same time;

[0065] Transmission mechanism 4: A transmission motor 401 is installed in the base 102, and its output shaft is connected to the first transmission gear 402, which is engaged with the second transmission gear 403 on the outer side of the first air inlet cylinder 206, driving the stirring hollow rod 201 to rotate at a speed of 10-15 rpm;

[0066] Positioning mechanism 6: A positioning rod 601 is fixed inside the top of the compost barrel 101, and a connecting sleeve 602 at the bottom is sleeved on the top of the mixing hollow rod 201. A sealing plug 603 is fixed inside the mixing hollow rod 201 to block the top of the mixing hollow rod 201 to prevent gas from escaping.

[0067] Compost preparation and feeding

[0068] Open the top cover 7 and put organic materials, such as straw and feces mixture, with a moisture content of 60% into the compost barrel 101. The filling amount should not exceed 70% of the barrel volume to avoid spillage;

[0069] Close the top cover 7, connect the pipe 208 to the blower with a wind pressure of 0.2 MPa, and check all sealing parts to ensure there is no air leakage;

[0070] Stirring and jetting work together

[0071] Start the equipment: Turn on the transmission motor 401, the mixing hollow rod 201 drives the spiral blade 202 to rotate, the bottom spiral blade 202 lifts the deep layer of material upward, and the top blade scatters the material to the surroundings, realizing the turning of the entire pile;

[0072] Synchronous jet: When the mixing hollow rod 201 rotates, the jet mechanism 3 rotates with it, and the fixed ball 305 rolls along the fixed cam 205. When the fixed ball 305 breaks away from the protrusion of the fixed cam 205, the telescopic rod 304 contracts under the action of the spring 310 to restore, so that the blocking head 302 and the blocking ring 307 move synchronously, opening the end exhaust hole 303 and the waist exhaust hole 306. The gas is ejected from the end exhaust hole 303 and the waist exhaust hole 306 through the mixing hollow rod 201 and the jet connecting pipe 301, with a gas volume of 0.5m 3 / min;

[0073] When the fixed ball 305 contacts the protrusion of the fixed cam 205, the spring 310 is compressed, and the blocking head 302 and the blocking ring 307 close the end exhaust hole 303 and the waist exhaust hole 306, completing one jet. Each set of jet mechanisms 3 jets once per rotation.

[0074] Composting and discharging

[0075] The operation lasts for 5 to 7 days, running for 8 hours a day. Oxygen is added by air jetting to maintain the oxygen content of the pile at 15% to 20%. The spiral blades 202 stir the material to keep the temperature uniform at 55-60°C, accelerating the decomposition.

[0076] After the composting is completed, the equipment is stopped, the discharge door 501 is opened, and the collection is completed;

[0077] In general, the gradually varying diameter design of the spiral blade 202 realizes the "lifting-scattering" cycle of the material, expanding the contact area between the material and the air. The air-jet mechanism 3 rotates synchronously with the stirring, and the fixed cam 205 and the spring 310 control the intermittent opening and closing of the exhaust hole. The air is ejected at the moment when the material is turned over, preventing gas from escaping and increasing the oxygen utilization rate by 40%.

[0078] The end exhaust hole 303 and the waist exhaust hole 306 respectively spray air to the material throwing area and the deep turning area, cooperate with the three-dimensional stirring of the spiral blade 202, ensure that the oxygen is uniformly distributed in each layer of the pile, eliminate anaerobic dead angle, and reduce the emission of hydrogen sulfide and other foul-smelling gases by more than 60%;

[0079] The fixed rod 204 and the positioning mechanism 6 ensure that the fixed cam 205 is stationary, and form stable linkage with the rotating air injection mechanism 3; the reinforcing sheet 203 and the hollow fixed frame 309 reduce material resistance while ensuring structural strength, thereby reducing energy consumption;

[0080] The embodiment solves the problem of uncoordinated ventilation and stirring of traditional composting equipment through the integrated design of stirring and air injection. The gradually changing diameter spiral blade 202 realizes full pile turning, cooperates with the intermittent air injection mechanism 3, and makes the material fully contact with oxygen, so that the composting period is shortened to 5-7 days (10-15 days for traditional equipment); the end exhaust hole 303 and the waist exhaust hole 306 are designed to be synchronously blocked to ensure directional injection of gas and improve oxygen utilization; it is suitable for large-scale organic fertilizer production, reduces energy consumption and foul-smelling emission, and improves product quality.

[0081] The working principle of the present application is as follows: when in use, the material to be composted is put into the composting barrel 101 of the composting mechanism 1, and according to the setting of the composting capacity, after the material is put in, the top cover 7 is closed with the top of the composting barrel 101 through the lifting ring 8;

[0082] The second air inlet cylinder 207 is connected with the external air source through the connecting pipeline 208, the pipeline can be installed through the through hole 104 at this time, and the pipeline connection is provided with a flange plate, which is convenient for connection and ensures the sealing of the air source;

[0083] When the material in the composting barrel 101 needs to be stirred, the transmission motor 401 of the transmission mechanism 4 drives the first transmission gear 402 to rotate, which drives the second transmission gear 403 to rotate, and since the second transmission gear 403 is fixed outside the first air inlet cylinder 206, and the first air inlet cylinder 206 is fixedly connected with the stirring hollow rod 201, the transmission mechanism 4 can drive the stirring hollow rod 201 to rotate at this time;

[0084] The spiral blades 202 are fixed to the outside of the mixing hollow rod 201. The spiral blades 202 rotate with the mixing hollow rod 201 to mix the compost material inside the compost barrel 101. Specifically, the diameter of the spiral blades 202 gradually increases from bottom to top, so that the spiral blades 202 with a small diameter at the bottom can generate a strong upward thrust, thereby "lifting" the dense material deep inside the compost barrel 101 upward. The spiral blades 202 with a large diameter at the top can naturally scatter the lifted material over a large area at a high position, thereby forming a full-body turnover with loosening at the bottom and scattering at the top, thereby avoiding the problem of local material retention.

[0085] Furthermore, when the stirring mechanism 2 rotates, the stirring hollow rod 201 simultaneously drives the multiple sets of jet mechanisms 3 to rotate synchronously, wherein the jet connecting pipes 301 of the jet connecting pipes 3 are connected to the internal cavity of the stirring hollow rod 201, and then the air flow from the external air source entering the interior of the stirring hollow rod 201 through the first air inlet cylinder 206 and the second air inlet cylinder 207 can enter the interior of the multiple sets of jet connecting pipes 301;

[0086] When the multiple jet mechanisms 3 rotate with the mixing hollow rod 201, since the mixing hollow rod 201 is provided with a fixed rod 204 inside, and the fixed rod 204 is provided with multiple fixed cams 205 that cooperate with the multiple jet mechanisms 3, the fixed rod 204 and the fixed cams 205 will not rotate with the mixing hollow rod 201;

[0087] When the jet mechanism 3 rotates, the fixed ball 305 of the jet mechanism 3 will perform a circular motion along the fixed cam 205. At the same time, under the action of the spring 310, the fixed ball 305 will separate from the raised part of the fixed cam 205, and then the telescopic rod 304 will be passively contracted, thereby driving the blocking head 302 and the blocking ring 307 to move axially along the jet connecting pipe 301 through the other end of the telescopic rod 304, so that the end exhaust hole 303 and the waist exhaust hole 306 are opened, and then the gas can be discharged into the compost barrel 101 through the end exhaust hole 303 and the waist exhaust hole 306, and come into contact with the material inside the compost barrel 101;

[0088] In general, the diameter of the spiral blades 202 in the equipment gradually increases from bottom to top. The small-diameter blades at the bottom can generate strong thrust to "lift" the deep and dense materials upward. The large-diameter blades at the top can make the lifted materials naturally scatter over a large area at a high position, forming a full pile turnover to avoid local material retention.

[0089] When the stirring mechanism 2 rotates, the multiple groups of air-jet mechanisms 3 rotate synchronously, and the external air source enters the air-jet communication pipe 301 through the air inlet cylinder and the stirring hollow rod 201. During the rotation process, the fixed cam 205 cooperates with the spring 310 to open the exhaust hole of the air-jet mechanism 3 in time to replenish the gas into the material. The stirring and air-jet are carried out synchronously, so that the material is fully contacted with the gas while being turned, thereby increasing the contact area, improving the contact efficiency, avoiding local hypoxia, promoting uniform decomposition of the compost material, and shortening the composting cycle.

[0090] At the same time, traditional equipment is prone to forming local anaerobic environments due to the lack of coordination between ventilation and stirring, which leads to the emission of malodorous gases such as hydrogen sulfide and ammonia. This equipment reduces the generation of local anaerobic environments through the synergistic effect of stirring and jetting, thereby reducing the emission of malodorous gases.

[0091] At the same time, a more complete decomposition process also reduces product quality problems caused by incomplete decomposition and improves the quality of compost products;

[0092] The linkage design of the stirring mechanism 2 and the air-jet mechanism 3 avoids the problems in traditional equipment where stirring destroys the ventilation path and materials hinder gas penetration during ventilation, allowing ventilation and stirring to proceed in a coordinated manner.

[0093] This coordinated working mode improves the overall composting efficiency, ensures the stability of the composting process, and helps to obtain better quality compost products.

[0094] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
