Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer composting technology, specifically to an organic fertilizer composting barrel. Background Technology

[0002] Organic fertilizers are primarily derived from plants and animals, and their main function, when applied to the soil, is to provide nutrients to plants. Processed from biological matter, animal and plant waste, and plant residues, they eliminate toxic and harmful substances, are rich in beneficial substances, promote microbial growth, and improve the physical, chemical, and biological activities of the soil. They are a key nutrient source for green food production. Compost refers to organic fertilizer made primarily from plant-based materials with added substances to promote organic matter decomposition under anaerobic conditions in flooded areas. It is suitable for use in water-rich regions of the south or for composting during the rainy season in the north. Organic matter decomposes under anaerobic conditions, resulting in a high humification coefficient and minimal nutrient loss. It is an organic fertilizer rich in organic matter and various nutrients, with a long-lasting effect and the function of improving soil fertility.

[0003] In existing technologies, conventional organic fertilizer composting tanks lack internal stirring functions during use, resulting in uneven distribution of composting materials. Furthermore, they cannot quickly heat the interior and provide oxygen during the composting process, leading to low composting efficiency and poor results. In addition, the lack of automatic pressure relief and exhaust functions during the process poses certain safety hazards. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model discloses an organic fertilizer composting barrel, including a barrel body 1.

A barrel cover 5 is threadedly installed on the upper surface of the cylinder 2, and a rubber ring is provided between the lower surface of the barrel cover 5 and the upper surface of the barrel body 1 to improve the sealing effect. An exhaust mechanism 6 is fixedly installed on the upper surface of the barrel cover 5 near the left side. An air distribution box 7 is fixedly installed in the upper middle part of the barrel cover 5. A motor 8 is fixedly installed on the upper surface of the air distribution box 7. A transmission mechanism 9 is fixedly installed on the lower surface of the output shaft of the motor 8, and the transmission mechanism 9 is connected to the stirring mechanism 4. An air injection mechanism 10 is provided on the right side of the air distribution box 7.

[0022] Specifically, the discharge mechanism 3 includes a spiral feeding rod 301, a bearing assembly 302, a rectangular opening 303, and a discharge valve 304. The spiral feeding rod 301 is fixedly installed on the lower inner wall of the cylinder 2 through the bearing assembly 302. Rectangular openings 303 are provided on the front and rear side walls of the cylinder 2 on the upper side of the lower side wall of the barrel 1. The discharge valve 304 is fixedly installed on the lower edge of the right side wall of the cylinder 2.

[0023] In this embodiment, the rectangular opening 303 allows the organic fertilizer in the barrel 1 to flow into the cylinder 2. Then, the screw feeder 301 rotates clockwise to move and roll the organic fertilizer upwards, and then flows out through the upper surface of the cylinder 2, so that the organic fertilizer is evenly distributed. When the screw feeder 301 rotates counterclockwise, the organic fertilizer flows towards the lower side of the cylinder 2, and the discharge valve 304 is opened to facilitate the discharge of the organic fertilizer.

[0024] Specifically, the stirring mechanism 4 includes a transmission pipe 401, an air distribution pipe 402, a branch pipe 403, and a one-way air outlet 404. The transmission pipe 401 is fixedly installed on the upper surface of the screw feeder 301. Air distribution pipes 402 are provided on both the left and right sides of the transmission pipe 401, and branch pipes 403 are uniformly fixedly installed on the lower surface of the air distribution pipes 402. One-way air outlets 404 are uniformly provided on the branch pipes 403.

[0025] In this embodiment, the transmission pipe 401 rotates with the transmission mechanism 9, causing the transmission pipe 401 to drive the air distribution pipe 402 to rotate, and the air distribution pipe 402 drives the branch pipe 403 and the one-way air outlet 404 to rotate, so that the air is evenly distributed in the barrel 1.

[0026] Specifically, the exhaust mechanism 6 includes a filter cylinder 601, a round hole 602, a filter element 603, a sealing cover 604, a safety valve 605, and an exhaust valve 606. The filter cylinder 601 is fixedly embedded in the barrel cover 5 near the left side. The round hole 602 is opened on the lower side wall of the filter cylinder 601. The filter element 603 is disposed inside the filter cylinder 601. The sealing cover 604 is threaded onto the upper surface of the filter cylinder 601. The safety valve 605 is disposed on the sealing cover 604. The exhaust valve 606 is disposed on the upper edge of the left side surface of the filter cylinder 601.

[0027] In this embodiment, when the gas pressure inside the barrel 1 is too high, the gas inside the barrel 1 flows into the filter cartridge 601 through the round hole 602. The filter element 603 inside the filter cartridge 601 adsorbs and purifies the gas by removing unpleasant odors, and then discharges it through the safety valve 605 on the sealing cover 604 to ensure that the gas pressure inside the barrel 1 is moderate. Alternatively, the exhaust valve 606 can be manually opened to discharge the gas inside the barrel 1.

[0028] Specifically, the transmission mechanism 9 includes a rotating shaft 901, a mechanical seal 902, and an air inlet 903. The rotating shaft 901 is installed on the lower surface of the output shaft of the motor 8 through the mechanical seal 902, and the air inlet 903 is provided on the rotating shaft 901 inside the air distribution box 7. The rotating shaft 901 is inserted into the transmission tube 401.

[0029] In this embodiment, the rotating shaft 901 rotates with the motor 8 in the mechanical seal 902, causing the rotating shaft 901 to drive the stirring mechanism 4 to rotate, and the gas in the air distribution box 7 on the air inlet 903 can flow into the rotating shaft 901.

[0030] Specifically, the portion of the rotating shaft 901 and the transmission tube 401 that are interlocked is a hollow structure in plan view. A rubber sealing ring 11 is fixedly installed on the lower surface of the rotating shaft 901, and the rotating shaft 901 is a hollow structure with openings on the upper and lower sides. A through hole 12 is provided on the barrel cover 5 corresponding to the rotating shaft 901.

[0031] In this embodiment, the rubber sealing ring 11 improves the sealing effect between the rotating shaft 901 and the transmission tube 401, the rotating shaft 901 can meet the gas flow requirements, and the through hole 12 meets the requirements for the rotating shaft 901 to be installed and rotated.

[0032] Specifically, the gas injection mechanism 10 includes a controller 101, a first temperature sensor 102, an oxygen concentration sensor 103, a second temperature sensor 104, a heating plate 105, a ventilation assembly 106, a first conduit 107, a three-way solenoid valve 108, and a second conduit 109. The controller 101 is installed on the right side of the barrel 1, and the first temperature sensor 102 and the oxygen concentration sensor 103 are embedded on the right side wall of the barrel 1 corresponding to the controller 101. The second temperature sensor 104 and the heating plate 105 are installed on the upper side wall and inner wall of the gas distribution box 7, respectively. The ventilation assembly 106 is installed on the upper surface of the barrel cover 5. The inlet and outlet of the ventilation assembly 106 are respectively connected to the gas distribution box 7 and the three-way solenoid valve 108 through the first conduit 107. The three-way solenoid valve 108 is respectively connected to the outside and the barrel cover 5 through the second conduit 109.

[0033] In this embodiment, the controller 101 detects the temperature and oxygen content of the organic fertilizer in the barrel 1 through the first temperature sensor 102 and the oxygen concentration sensor 103. When the temperature is lower than the set value, the exhaust assembly 106 extracts air from the barrel 1 through the first conduit 107, the three-way solenoid valve 108 and the second conduit 109. The extracted gas flows into the gas distribution box 7 and is then heated by the electric heating plate 105. The heated gas flows into the organic fertilizer in the barrel 1 through the transmission mechanism 9 and the stirring mechanism 4, thereby heating the organic fertilizer and preventing external gas from entering the barrel 1. When the oxygen content is too low, the three-way solenoid valve 108 is connected to the outside through another second conduit 109, allowing external air to enter the barrel 1 and oxygenating the organic fertilizer.

[0034] In use, the main and auxiliary organic fertilizer materials are poured into the barrel 1, and the barrel lid 5 is threaded onto the upper surface of the barrel 1 to seal it. The output shaft of the motor 8 drives the rotating shaft 901 in the transmission mechanism 9 to rotate, which in turn drives the transmission pipe 401 in the mixing mechanism 4 to rotate. The transmission pipe 401 drives the air distribution pipe 402 to rotate, which in turn drives the branch pipe 403 and the one-way air outlet 404 to rotate. The transmission pipe 401 also drives the screw feeder 301 in the discharge mechanism 3 to rotate clockwise. The screw feeder 301 causes the organic fertilizer to move upward and tumble, and then flow out through the upper surface of the cylinder 2, so that the organic fertilizer is evenly distributed. When rod 301 rotates counterclockwise, the organic fertilizer flows towards the lower side of cylinder 2, opening discharge valve 304 to facilitate discharge of the organic fertilizer. This mixes the main and auxiliary organic fertilizer materials in barrel 1. The controller 101 in the gas injection mechanism 10 detects the temperature and oxygen content of the organic fertilizer in barrel 1 via the first temperature sensor 102 and oxygen concentration sensor 103. When the temperature is lower than the set value, the exhaust assembly 106 extracts air from barrel 1 through the first conduit 107, three-way solenoid valve 108, and second conduit 109. The extracted gas flows into the gas distribution box 7 and is then heated by the heating plate 105. The heated gas then passes through the air inlet 9. 03 flows into the rotating shaft 901, then through the rotating shaft 901 into the transmission pipe 401, then through the transmission pipe 401 into the air distribution pipe 402 and branch pipe 403, and finally into the barrel 1 through the one-way air outlet 404, achieving the effect of heating the organic fertilizer and preventing external gas from entering the barrel 1. When the oxygen content is too low, the three-way solenoid valve 108 is connected to the outside through another second conduit 109, allowing external air to enter the barrel 1, which can quickly and evenly heat the interior and distribute oxygen, making the temperature and oxygen content suitable for organic fertilizer composting, resulting in higher composting efficiency and better effect. During the composting process, when the air pressure inside the barrel 1 is too high, the barrel 1... The internal gas flows into the filter cylinder 601 through the round hole 602 in the exhaust mechanism 6. The filter element 603 in the filter cylinder 601 adsorbs and purifies the unpleasant odor of the gas, and then discharges it through the safety valve 605 on the sealing cover 604, ensuring that the gas pressure inside the barrel 1 is moderate. Alternatively, the exhaust valve 606 can be manually opened to discharge the gas inside the barrel 1, ensuring that the gas pressure inside the barrel 1 is moderate and purifying the unpleasant odor in the discharged gas, making it safer and more environmentally friendly to use. After the fermentation is completed, the motor 8 drives the rotating shaft 901 to rotate in the opposite direction. The rotating shaft 901 drives the spiral feeding rod 301 on the lower surface of the transmission tube 401 to rotate in the opposite direction, opening the discharge valve 304 to discharge the organic fertilizer.

[0035] In summary, this organic fertilizer composting tank enhances the mixing of main and auxiliary organic fertilizer materials, resulting in more uniform mixing. It also enables rapid and even heating and oxygen distribution within the tank, leading to higher composting efficiency and better results. Furthermore, it facilitates material discharge, incorporates an automatic venting function, and purifies unpleasant odors from the exhaust gas, making it safer and more environmentally friendly to use.
