Abstract
Description
Technical Field
[0001] This utility model belongs to the field of organic solid waste treatment technology, and more specifically, it relates to an automatic composting bed. Background Technology
[0002] Vermicomposting is a method of processing organic waste using earthworms. Earthworms play a crucial role in this process: through eating garbage, burrowing, and utilizing their powerful digestive enzymes (proteases and lipases), along with the action of microorganisms in the garbage dump, they thoroughly decompose the organic waste into nutrients easily absorbed by plants, greatly accelerating the composting process.
[0003] Furthermore, earthworms produce a valuable byproduct during decomposition – vermicompost. Known as the "king of organic fertilizers," vermicompost is highly decomposed (with a high degree of mineralization) and rich in various trace elements. Therefore, vermicompost has enormous potential in agriculture and the environment, as it can improve soil, aid plant growth, and even absorb gases.
[0004] In existing technologies, during vermicomposting, mixing is typically achieved by using agitators to ensure even distribution of the earthworms within the compost bed. However, when these agitators (such as paddles or augers) rotate or move within the compost, they can directly cut, squeeze, or impact the earthworms, causing injury or even death, significantly reducing their survival rate and mobility.

[0022] Vermicomposting is a method of processing organic waste using earthworms. Earthworms play a crucial role in this process: through eating garbage, burrowing, and utilizing their powerful digestive enzymes (proteases and lipases), along with the action of microorganisms in the garbage dump, they thoroughly decompose the organic waste into nutrients easily absorbed by plants, greatly accelerating the composting process.
[0023] Furthermore, earthworms produce a valuable byproduct during decomposition – vermicompost. Known as the "king of organic fertilizers," vermicompost is highly decomposed (with a high degree of mineralization) and rich in various trace elements. Therefore, vermicompost has enormous potential in agriculture and the environment, as it can improve soil, aid plant growth, and even absorb gases.
[0024] In existing technologies, during vermicomposting, mixing is typically achieved by using agitators to ensure even distribution of the earthworms within the compost bed. However, when these agitators (such as paddles or augers) rotate or move within the compost, they can directly cut, squeeze, or impact the earthworms, causing injury or even death, significantly reducing their survival rate and mobility.
[0025] Please see Figures 1 to 6The automatic composting bed provided by this utility model will now be described. The automatic composting bed includes a housing 10, a composting hopper 20, four elastic elements 30, and a vibrating element 40. The housing 10 has an upward opening; the composting hopper 20 is disposed above the housing 10 and has an upward opening for accommodating the compost pile; the four elastic elements 30 are arranged in a rectangle between the housing 10 and the composting hopper 20 and extend in the vertical direction. The upper part of the elastic element 30 is fitted with a first mounting cylinder 31 disposed at the bottom of the composting hopper 20, and the lower part of the elastic element 30 is fitted with a second mounting cylinder 32 disposed at the top of the housing 10; the vibrating element 40 is disposed on the outer wall of the composting hopper 20; wherein, the vibrating element 40 can drive the composting hopper 20 to shake so that the compost pile is spread flat inside the composting hopper 20.
[0026] Furthermore, a controller is located on one side of the chassis 10.
[0027] Furthermore, a feed hopper connected to the compost hopper 20 is provided above the compost hopper 20.
[0028] This application provides an automated composting bed in which four rectangularly arranged elastic elements 30 (such as springs) form a stable suspension system, suspending the compost hopper 20 above the housing 10. This design allows the compost hopper 20 to undergo effective and controlled multidimensional swaying (not just up-and-down vibration) driven by the vibrating element 40.
[0029] The force generated by the vibrating component 40 (such as a vibrating motor) is efficiently transmitted to the entire compost bin 20 through an elastic suspension system. This shaking mimics the action of manual turning of the compost pile, but it is more uniform, less labor-intensive, and more automated. It can effectively break up clumps of compost pile material, allowing the pile material to be automatically and evenly spread out in the bin.
[0030] The design of the first mounting cylinder 31 (bottom of compost hopper 20) and the second mounting cylinder 32 (top of chassis 10) is crucial. They not only provide fixing points for the elastic element 30, but more importantly, they play a guiding and limiting role, ensuring that the elastic element 30 mainly expands and contracts in the vertical direction when subjected to force, preventing lateral displacement or twisting, thereby ensuring the efficiency of vibration transmission and the controllability and stability of the swaying trajectory of the compost hopper 20.
[0031] A flat compost heap has a larger surface area and more uniform porosity, which is conducive to the uniform penetration of oxygen (promoting the activity of aerobic microorganisms), the uniform distribution of heat (avoiding local overheating or low temperature zones), and the uniform evaporation or absorption of moisture, thereby creating a better composting reaction environment, accelerating the maturation process, and reducing odor generation.
[0032] The vibration of the composting hopper 20 by the vibrator 40, in conjunction with the elastic element 30, enables the composting hopper 20 to undergo effective and controlled multi-dimensional shaking, which can effectively break up the clumps of compost, allowing the compost to spread out automatically and evenly within the hopper, thus preventing earthworms from being injured or even dying, and significantly improving the survival rate and activity of earthworms.
[0033] Compared with the prior art, the automatic composting bed provided in this embodiment uses the vibration of the vibrating element 40 to vibrate the composting hopper 20, and with the cooperation of the elastic element 30, the composting hopper 20 can perform effective and controlled multi-dimensional shaking, which can effectively break up the clumps of compost, so that the compost can be automatically and evenly spread out in the hopper, avoiding injury or even death to earthworms, and significantly improving the survival rate and activity of earthworms.
[0034] In one possible implementation, the aforementioned compost bin 20 adopts, as follows: Figures 1 to 3 The structure shown is described in the following document. Figures 1 to 3 The top of the compost hopper 20 is provided with a portal frame 21 spanning above the compost hopper 20. Above the portal frame 21 is a first telescopic member 50 that extends downward through the top of the portal frame 21. The lower part of the first telescopic member 50 is provided with a detection member 51. The first telescopic member 50 can drive the detection member 51 to be inserted into the compost pile.
[0035] Specifically, the portal frame 21 provides a stable and elevated support point. The first telescopic member 50 (such as an electric actuator or cylinder) can precisely control the vertical insertion of the detection elements 51 (including temperature sensors, humidity sensors, pH sensors, and carbon dioxide sensors) into the pile body at different depths.
[0036] The system acquires real-time physicochemical parameters (temperature, humidity, pH, and carbon dioxide content) of the core area of the compost pile through the detection component 51, providing crucial data for the automated control of the composting process. Based on this data, the system can intelligently adjust environmental conditions to ensure the composting process remains optimal, thereby improving composting efficiency and quality.
[0037] Furthermore, the controller is electrically connected to the detection element 51.
[0038] In some embodiments, see Figure 2 The portal frame 21 is provided with a horizontally extending groove strip 22 extending to the outside of the portal frame 21, and the groove strip 22 is provided with a water spraying device 52 for spraying water into the compost hopper 20.
[0039] Specifically, the water spraying element 52 (such as a nozzle) is positioned on the horizontally extending trough strip 22, higher than the opening of the compost hopper 20, so that the sprayed water mist or stream can cover a larger area and be more evenly distributed on the surface of the compost pile. This is crucial for regulating the moisture content of the compost.
[0040] Combined with the humidity detection mentioned above, the system can automatically trigger water spraying through the controller to replenish the moisture evaporated during composting or adjust the initial humidity of the material, maintaining the optimal humidity environment required for microbial activity without the need for manual watering.
[0041] Furthermore, the water spray component 52 is electrically connected to the controller.
[0042] In some embodiments, see Figure 1 and Figure 2 The grooved strip 22 is equipped with a blower 53 for blowing air into the compost hopper 20.
[0043] Specifically, the blower 53 (such as a fan) is mounted on the trough slats 22, which forces air into the compost hopper 20. This is crucial for the aerobic composting process, directly providing the oxygen needed for microorganisms to decompose organic matter.
[0044] Forced ventilation can accelerate the evaporation of moisture on the surface of the reactor (helping to dehumidify when humidity is too high), and helps to dissipate heat and exhaust gases (such as ammonia and hydrogen sulfide) generated inside the reactor, lowering the reactor temperature (preventing overheating from killing beneficial microorganisms), while introducing fresh air.
[0045] Furthermore, the blower 53 is electrically connected to the controller.
[0046] In one possible implementation, the aforementioned compost bin 20 adopts, as follows: Figures 2 to 4 The structure shown is described in the following document. Figures 2 to 4 The composting hopper 20 has a horizontally extending air duct 56 on its inner bottom wall and an air outlet on its outer peripheral wall. The air duct 56 is supplied with air through an air supply component 57.
[0047] Specifically, the horizontal ventilation duct 56 is installed on the inner bottom wall of the compost hopper 20, and the air outlets (such as small holes or gaps) on its outer peripheral wall can supply air directly upward from the bottom of the compost pile. This solves the problem that surface ventilation alone is not enough to effectively penetrate the entire compost pile, especially the central area which is prone to oxygen deficiency.
[0048] The air duct 56 extends horizontally, with air outlets distributed on its outer peripheral wall, which helps to distribute airflow relatively evenly on the bottom plane of the compost hopper 20, allowing oxygen to reach each layer of the compost pile more effectively.
[0049] Deep oxygen supply greatly promotes the activity of aerobic microorganisms inside the compost pile, significantly accelerates the decomposition rate of organic matter, reduces the putrefaction and odor caused by anaerobic areas, and improves the quality of the final compost product.
[0050] The bottom air duct 56 supplies air and the top air blowing component 53 blows air to form a three-dimensional ventilation network, which optimizes the oxygen distribution, exhaust gas discharge and cooling inside the reactor in all aspects.
[0051] Furthermore, the gas supply unit 57 is electrically connected to the controller.
[0052] Furthermore, the air supply component 57 is an air compressor installed inside the housing 10, and one end of the air compressor is connected to the air duct 56 via a first flexible hose (not shown in the figure).
[0053] In one possible implementation, the aforementioned compost bin 20 adopts, as follows: Figure 4 and Figure 5 The structure shown is described in the following document. Figure 4 and Figure 5 A discharge port 23 is provided through one side wall of the compost hopper 20. A drain pipe 24 for discharging leachate is provided on the inner bottom wall of the compost hopper 20. The drain pipe 24 is located near the discharge port 23. A water-blocking strip 25 is provided on the inner bottom wall of the compost hopper 20 on the side of the drain pipe 24 near the discharge port 23. The two ends of the water-blocking strip 25 are respectively connected to the opposite side walls of the compost hopper 20 near the discharge port 23.
[0054] Specifically, the excess water (leachate) generated during composting is rich in nutrients but may also be highly concentrated and have an odor. The drain pipe 24 is specially designed on the inner bottom wall near the discharge port 23, and together with the water baffle strip 25, it forms a local liquid collection area.
[0055] The water-blocking strip 25 is located on the side of the drain pipe 24 near the discharge port 23, with both ends connected to the side walls, forming a "dam". Its core function is to ensure that the leachate can flow smoothly and automatically into the drain pipe 24, while initially separating the leachate from the solid compost that is about to be discharged.
[0056] In some embodiments, see Figure 4 The compost hopper 20 has a water guide strip 26 on its inner bottom wall, which is parallel to the water baffle strip 25. The water guide strip 26 is located inside the water baffle strip 25. The drain pipe 24 is located between the water baffle strip 25 and the water guide strip 26. There is a passage gap 27 between the water guide strip 26 and the inner wall of the compost hopper 20.
[0057] Specifically, a parallel water guide strip 26 is added to the inside of the water-blocking strip 25 (outer side), forming a more defined flow channel between the two, and the drain pipe 24 is located in this channel.
[0058] The presence of the water guide strip 26 forces leachate from the bottom of the compost hopper 20, except for the area near the two side walls of the discharge port 23 (through the gap 27), to first flow into the area between the water baffle strip 25 and the water guide strip 26 before it can be discharged through the drain pipe 24. This significantly improves the leachate collection efficiency and reduces the possibility of liquid residue remaining in other corners of the compost hopper 20.
[0059] The channel formed by the two water strips guides the liquid more effectively, while further preventing solid materials from directly impacting the drain pipe 24.
[0060] In some embodiments, see Figure 3 The casing 10 is provided with a swing frame 60 located at the lower end of the second mounting cylinder 32. The casing 10 is provided with a fixed frame 61 located below the swing frame 60. The swing frame 60 is hinged to the fixed frame 61. A second telescopic member 62 is provided between the fixed frame 61 and the swing frame 60. The two ends of the second telescopic member 62 are respectively hinged to the fixed frame 61 and the swing frame 60. The second telescopic member 62 can drive the swing frame 60 to swing vertically so that the pile slides down from the discharge port 23.
[0061] Specifically, the swing frame 60 is hinged to the fixed frame 61, and the second telescopic member 62 is hinged at both ends for drive. When the telescopic member extends or retracts, it pushes the swing frame 60 (along with the second mounting cylinder 32, elastic member 30, and compost hopper 20 on it) to swing vertically around the hinge point (i.e., one end is raised). This causes the entire compost hopper 20 to tilt.
[0062] After the composting hopper 20 tilts towards the discharge port 23, the composted material inside automatically slides towards the discharge port 23 and is discharged under the action of gravity, completely eliminating the heavy physical labor of manually digging out the material.
[0063] By controlling the stroke of the second telescopic component 62, the tilt angle of the compost hopper 20 can be precisely controlled, thereby controlling the discharge speed and flow rate.
[0064] In some embodiments, see Figures 1 to 3 A sealing plate 70 for sealing the discharge port 23 is slidably connected to the compost hopper 20 along the vertical direction. The sealing plate 70 is located on the side of the drain pipe 24 away from the water baffle 25. There is an clearance between the sealing plate 70 and the inner bottom wall of the compost hopper 20 to allow leachate to pass through.
[0065] Specifically, the sealing plate 70 is slidably connected to the compost hopper 20 in the vertical direction to seal or open the discharge port 23. This provides precise control over the discharge operation.
[0066] The clearance ensures that leachate generated in the compost hopper 20 can flow smoothly through the clearance to the drain pipe 24 area and be discharged, regardless of the state of the sealing plate 70. This resolves the conflict between the sealing of the discharge port 23 and the need for continuous drainage.
[0067] Furthermore, the sealing plate 70 is connected to the compost hopper 20 via a rodless cylinder.
[0068] In some embodiments, see Figure 3 The casing 10 is equipped with a sewage tank 80 that is connected to the drain pipe 24, and a clean water tank 90 located below the sewage tank 80 and connected to the sewage tank 80.
[0069] Specifically, the wastewater tank 80 is connected to the drain pipe 24 via a second flexible hose (not shown in the figure) for the purpose of collecting and storing leachate discharged from the compost hopper 20. This prevents the direct discharge of leachate and the resulting environmental pollution.
[0070] The clean water tank 90 is located below and connected to the wastewater tank 80. This connection allows the collected leachate to first be stored in the wastewater tank 80 and then undergo some form of preliminary sedimentation treatment. Afterward, the treated or diluted liquid can flow into the clean water tank 90 below.
[0071] The liquid (preliminarily treated leachate or mixed clean water) stored in the clean water tank 90 can be reused, for example, by being sprayed back into a new pile via the water spray unit 52. This achieves internal recycling of water resources, reduces the consumption of fresh water, and recovers nutrients from the leachate.
[0072] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
