Description
Technical Field
[0001] The present application relates to the technical field of garden fermentation, and in particular to a high-efficiency fermentation and molding equipment for resource utilization of garden waste. Background Art
[0002] Garden waste consists of organic matter such as fallen branches and leaves, grass clippings, and flower scraps generated through urban landscaping and park pruning. To recycle this waste, it is first crushed into 5-10 cm segments for subsequent processing. Subsequently, the material is adjusted according to the carbon-nitrogen ratio, and appropriate microbial inoculants are added. Through composting and fermentation, it is converted into humus. During the composting process, the pile must be turned regularly to ensure oxygen supply and to maintain a temperature of 50-65°C to kill pathogens and insect eggs. After two to three months, fully decomposed organic fertilizer is obtained.
[0003] Conventional fermentation methods are mainly natural composting and high-temperature composting. Natural composting is to pile up garden waste in an open field and rely on natural microorganisms to slowly decompose it. This method is time-consuming, prone to producing odors and mosquitoes, and the degree of decomposition is uneven. High-temperature composting is artificially controlled by adding high-efficiency microbial agents to increase the fermentation temperature and accelerate the decomposition of organic matter. It can produce high-quality organic fertilizer in a relatively short period of time and can also effectively kill harmful pathogens and weed seeds. It is currently the more commonly used method for fermenting garden waste. The specific method is: the crushed garden waste is placed in a fermentation bag and piled up somewhere in the garden. Personnel regularly open the fermentation bag to stir, control the temperature, and spray water. Stirring not only controls the temperature in the center of the fermentation bag but also replenishes oxygen inside to ensure aerobic fermentation.
[0004] In order to reduce the floor space, the fermentation bags are centrally stacked. When the compost in each fermentation bag needs to be stirred and the temperature controlled, the fermentation bags located in the middle area of the stack are inconvenient to stir. Summary of the Invention
[0005] In order to reduce the floor space occupied by the fermentation bag and improve the convenience of stirring inside the fermentation bag, the present application provides an efficient fermentation and molding equipment for resource utilization of garden waste.
[0006] The present application provides an efficient fermentation and molding equipment for resource utilization of garden waste, which adopts the following technical solutions: A high-efficiency fermentation and molding equipment for resource utilization of garden waste includes multiple fermentation chambers, guide rails and carrier plates. The guide rails are fixed on the ground of the garden, and the carrier plates are slidably arranged on the guide rails. Adjacent fermentation chambers are buried in the ground of the garden at intervals along the length direction of the guide rails. The tops of the fermentation chambers are all provided with covers. The moving path of the carrier plates skips over the tops of the covers. A stirring rod is provided on the carrier plates, which penetrates the carrier plates and extends deep into the fermentation chambers. The stirring rod is arranged to rotate relative to the carrier plates and slide relative to the carrier plates in a vertical direction. A first driving component for driving the stirring rod to rotate and a second driving component for driving the stirring rod to slide are provided on the carrier plates.
[0007] By adopting this technical solution, the fermentation chambers are buried in the ground, reducing the equipment's footprint. The sliding coordination of the guide rails and the carrier plate allows the stirring rod to be precisely positioned above any fermentation chamber. The stirring rod's rotation and vertical sliding functions allow it to penetrate deep into the fermentation bags for three-dimensional stirring, improving the convenience of stirring the fermentation bags. When the fermentation bags are stacked together, the carrier plate moves along the guide rails to cover all the fermentation chambers, solving the problem of inconvenient stirring of fermentation bags in the middle area of traditional stacking methods. At the same time, temperature control and oxygen supply can be achieved simultaneously during the turning process, improving fermentation efficiency and uniformity.
[0008] Optionally, the first driving assembly includes a first motor, a first gear, a second gear and a third gear, the first motor is fixed at the center of the carrier plate, the first gear ring is fixed on the output shaft of the first motor, the second gear and the third gear are meshed and both are rotatably set on the carrier plate, the first gear and the second gear are both vertically set and meshed with each other, the third gear is horizontally set, the stirring rod passes through the center of the third gear, and the third gear drives the stirring rod to rotate synchronously.
[0009] By adopting this technical solution, the first motor converts vertical driving force into horizontal rotational power through the meshing transmission of the first, second, and third gears, providing the stirring rod with stable rotational torque. This compact transmission structure and precise transmission ratio allow the stirring speed to be adjusted according to fermentation needs. The gear meshing transmission also ensures reliable power transmission during the stirring rod's rotation, preventing slippage that could affect the fermentation and compost turning effect.
[0010] Optionally, the carrier plate includes an outer ring and an inner circle, the outer ring surrounds the inner circle, the inner circle is arranged to rotate relative to the external aid, the first motor is fixed at the center of the inner circle, and the stirring rod passes through the inner circle adjacent to the first motor; a fourth gear is fixed on the ring sleeve of the output shaft of the first motor, and a gear ring is fixed on the outer ring, the gear ring surrounds the inner circle, and the fourth gear is meshed with the gear ring.
[0011] By adopting this technical solution, the inner circle rotates relative to the outer circle, allowing the stirring rod to achieve 360° rotation while moving with the carrier plate. The engagement of the fourth gear and the ring gear allows the stirring rod to achieve 360° coverage. When the carrier plate is positioned above the fermentation chamber, the inner circle's rotation drives the stirring rod to adjust its angle, ensuring that the stirring range reaches all areas of the fermentation bags. This ensures that even bags stacked in corners can be stirred without blind spots, further improving mixing uniformity.
[0012] Optionally, a through hole and a through groove are opened in the vertical direction at the center of the third gear, the through groove is located on the hole wall of the through hole, the stirring rod passes through the through hole and the circumferential outer wall slides and abuts against the hole wall of the through hole, a convex strip is fixed on the outer wall of the stirring rod, the convex strip is arranged along the length direction of the stirring rod, and the convex strip is located in the through groove.
[0013] By adopting this technical solution, the sliding cooperation between the through-slot and the ridges enables the stirring rod to slide vertically and, driven by the third gear, to rotate. This structure not only ensures the flexible movement of the stirring rod, but also prevents it from shifting during rotation by limiting its circumferential position via the ridges. This ensures that the stirring rod can stably perform the turning action when it reaches deep into the fermentation bag, thereby improving the reliability of the equipment.
[0014] Optionally, the second drive assembly includes a second motor and a fifth gear, the second motor is fixed on the top of the third gear, the output end of the second motor is fixedly connected to the fifth gear, the convex bar is rack-shaped, and the fifth gear is meshed with the convex bar.
[0015] By employing this technical solution, the second motor drives the fifth gear, which meshes with the rack-like ridges, converting the motor's rotational motion into vertical sliding motion of the stirring rod. This drive method offers high transmission efficiency and precise control of the stirring rod's height, adapting to the stirring requirements of fermentation bags of varying depths. When turning the material deep within the fermentation bag, the second drive assembly adjusts the stirring rod's insertion depth to ensure even mixing of the upper and lower layers of the fermentation material.
[0016] Optionally, a support rod is fixed on the carrier plate, and the top end of the support rod is rotatably connected to the center of the second gear.
[0017] By adopting this technical solution, the support rod forms a stable support point for the second gear, reducing wobble and deformation during gear transmission. This structure ensures the meshing accuracy of the first and second gears, preventing transmission failure due to gear offset, while also extending the service life of the transmission assembly and ensuring smoother and more reliable transmission of the stirring rod's rotational power.
[0018] Optionally, a support is fixed on the carrier plate, and the top of the support is rotatably connected to the third gear.
[0019] By adopting this technical solution, the support provides rotational support for the third gear, ensuring that the third gear maintains a horizontal and stable position as it rotates the stirring rod. This structure reduces friction loss between the third gear and the carrier plate while ensuring that the stirring rod remains vertical during rotation, preventing tilt from affecting the stirring effect and ensuring uniform turning of the material inside the fermentation bag.
[0020] Optionally, a roller brush is rotatably provided on the support, the roller brush is horizontally arranged, the bristles of the roller brush abut against the protrusion, and the roller brush is located below the third gear.
[0021] By adopting this technical solution, the bristles of the roller brush abut against the ribs, removing material debris from the ribs' surfaces as the agitator bar is raised and lowered. This design prevents material accumulation from affecting the meshing transmission between the ribs and the fifth gear, while also preventing debris from falling into the transmission assembly and causing equipment failure. This improves the equipment's self-cleaning capabilities and long-term operational stability.
[0022] Optionally, a belt is looped between the output shaft of the second motor and the roller brush, the belt is in a tensioned state, and the belt passes through the third gear.
[0023] By adopting this technical solution, a belt synchronously transmits power from the second motor to the roller brush, causing it to rotate and clean in sync with the raising and lowering of the stirring rod. This transmission method achieves the combined functions of stirring and cleaning without the need for an additional power source, reducing energy consumption while ensuring continuous cleaning of the ribs and gear transmission system, thereby improving equipment operating efficiency.
[0024] Optionally, the stirring rod includes an end section and multiple unit sections spliced together, an auger is fixed to the outer wall of the end section, both the unit section and the end section are hollow tubular, a connector is provided at the end of the stirring rod, one end of the connector is fixed to the end of the stirring rod, and the other end is connected to an external air pump, a bearing is provided in the middle of the connector itself for relative rotation at its two ends, and an air outlet is provided on the stirring rod.
[0025] By adopting this technical solution, the auger-shaped end section generates an axial thrust during stirring. This, combined with the hollow tubular structure connected to the air pump, enables simultaneous turning and oxygen supply. The unit segment's splicing design allows for flexible adjustment of the stirring rod length according to the depth of the fermentation bag. The bearing-connected connector prevents the air pump tubing from becoming entangled in the stirring rod during rotation. This structure not only ensures oxygen supply during fermentation, but also improves material mixing efficiency through auger stirring, shortening the fermentation cycle.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Improved space utilization and operational convenience: By burying the fermentation chamber underground, the equipment's footprint on the garden floor is effectively reduced. The sliding coordination of the guide rail and the carrier plate allows the stirring rod to be quickly and accurately moved to any fermentation chamber, completely solving the problem of inconvenient stirring in the middle area when traditional fermentation bags are centrally stacked. This significantly improves operational convenience and work efficiency. 2. Efficient stirring and mixing: The dual functions of the stirring rod's rotation and vertical sliding, combined with the rotation of the inner circle of the carrier plate relative to the outer circle, achieve three-dimensional, all-round stirring of the materials in the fermentation bag. Not only does it ensure that the materials in every corner of the fermentation bag are fully mixed, but the insertion depth and speed of the stirring rod can be adjusted to meet the needs of different fermentation stages, greatly improving the uniformity and efficiency of fermentation. 3. Multifunctional integration and intelligent cleaning: The auger structure and hollow tubular design of the stirring rod achieve the simultaneous operation of turning the compost and supplying oxygen, effectively shortening the fermentation cycle; the linked cleaning mechanism of the roller brush and the second motor can automatically remove material residues on the surface of the convex bar during the stirring process without the need for an additional power source, reducing the risk of equipment failure and manual maintenance costs, and improving the long-term operational stability and intelligence of the equipment.
