Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizers, and in particular to an aeration device for an organic fertilizer pile. Background Art

[0002] Organic fertilizer, also known as farmyard manure, refers to materials that use organic matter as fertilizer. These materials mainly come from human and animal feces and animal and plant residues, and are made through fermentation and decomposition. Aeration refers to the provision of sufficient oxygen to aerobic microorganisms in the compost to promote their respiratory metabolism, thereby accelerating the rapid decomposition of substances such as protein, starch and monosaccharides in the pile, generating a large amount of heat and promoting rapid temperature rise of the pile.

[0003] After searching, the publication number CN220537721U discloses an aeration device for composting organic fertilizer, which is roughly described as including an aeration frame, the lower side of the right side of the aeration frame is connected to a drainage structure, and the left side of the aeration frame is provided with an oxygen supply mechanism for adjusting the oxygen supply amount provided by the organic fertilizer pile. The aeration device for composting organic fertilizer, by opening the first valve and then starting the fan, conveys the air from the outside to the inside of the connecting pipe through the filter cartridge, and the air inside the connecting pipe flows to the inside of the air outlet plate, and then passes through the air outlet nozzles connected to the upper surface of the air outlet plate, which are not less than two in number, to evenly supply oxygen to the organic fertilizer raw materials, thereby improving the uniformity of oxygen supply, and by adjusting the inverter body, the size of the fan air volume can be adjusted, which is convenient for supplying oxygen to different organic fertilizers, and the liquid accumulated inside the aeration frame can be discharged through the drainage structure.

[0004] The above technical solution adopts the method of adding a filter mesh inside the aeration frame to prevent the raw materials from clogging the air outlet. Although this method can effectively avoid the raw materials from clogging the air outlet, when in use, a large amount of raw materials are accumulated on the top of the filter mesh plate. Since the filter mesh is in a parallel state, part of the raw materials will fit with the filter mesh during the collection process, making it difficult to completely remove them. If a tough method is used for collection, some of the raw materials will enter the holes of the filter mesh, clogging the filter mesh, making it difficult to clean. Utility Model Content

[0005] The purpose of the utility model is to provide an aeration device for an organic fertilizer compost pile, so as to solve the problem that a large amount of raw materials are piled up above the filter screen plate. Since the filter screen is in a parallel state, part of the raw materials will fit with the filter screen during the collection process, making it difficult to completely remove them. If a tough method is used for collection, part of the raw materials will enter the holes of the filter screen, clogging the filter screen and causing the problem of being difficult to clean.

[0006] The utility model provides the following technical scheme: an aeration device for an organic fertilizer compost pile, comprising a compost box, an outer side wall of the compost box being symmetrically fixedly connected with a fixing plate, an upper top end of the fixing plate being fixedly connected with an electric push rod, a telescopic end of the electric push rod being fixedly connected with a connecting plate, a lower bottom end of the connecting plate being fixedly connected with a first sealing cover plate, the first sealing cover plate being located at the upper top end of the compost box, a filter plate being arranged inside the compost box, a traction assembly for turning over the filter plate being arranged on the outer side wall of the compost box, and an aeration assembly for transmitting gas being arranged on the outer side wall of the compost box.

[0007] By adopting the above scheme, the opening and closing of the composting bin can be controlled by the electric push rod, thereby enhancing the stability and sealing of the composting bin. The filter plate arranged inside the composting bin can effectively filter out the wastewater generated during the composting process. At the same time, by adopting the aeration component for gas transmission, it can ensure that the oxygen supply during the composting process is uniform and sufficient, thereby improving the efficiency and effect of the composting. The traction component can flip the filter plate, thereby increasing the flexibility and practicality of the device, and can be adjusted according to usage requirements.

[0008] As a preferred embodiment of the above technical solution, the traction assembly includes a servo motor fixedly connected to the outer wall of the compost box, the output end of the servo motor is fixedly connected to a driving rod, the end of the driving rod is rotatably connected to a bearing frame, the end of the bearing frame is fixedly connected to the outer wall of the compost box, the outer wall of the driving rod is fixedly sleeved with a winding drum, the outer wall of the winding drum is wound with a steel cable, the upper top of the compost box is symmetrically fixedly connected to a guide wheel frame, the steel cable is wound inside the guide wheel frame, and the end of the steel cable is fixedly connected to a locking hook.

[0009] By adopting the above scheme, the servo motor can drive the driving rod and the winch drum to rotate. When the winch drum rotates, the steel cable is in a contracted state, which can drive the locking hook to retract. The guide wheel frame provides a stable guide for the steel cable to prevent the steel cable from deflecting or getting entangled during movement, thereby improving the safety and reliability of the equipment. The use of the bearing frame ensures that the driving rod is stable and reliable during rotation, reducing equipment failures and wear caused by vibration or deflection.

[0010] As a preferred embodiment of the above technical solution, the traction assembly also includes a first fixed bracket fixedly connected to the inner wall of the compost box, the filter plate is rotatably connected to the end of the first fixed bracket, the upper top of the filter plate is symmetrically fixedly connected to the second fixed bracket, and the locking hook is sleeved on the inner top of the second fixed bracket.

[0011] With the above solution, the use of the first fixed bracket provides a stable support and rotation point for the filter plate, making the filter plate more stable and less prone to shaking when rotating, while the second fixed bracket can rotate the filter plate under the drive of the locking hook.

[0012] As a preferred embodiment of the above technical solution, the outer wall of the compost box is located at the lower bottom end of the servo motor and is fixedly connected to a sealing box, and the outer wall of the compost box corresponding to the top and bottom of the filter plate are respectively fixedly connected to a first material guide rack and a second material guide rack, the end of the first material guide rack is rotatably connected to the second sealing plate, the second material guide rack and the first material guide rack are both located inside the sealing box, and the end of the sealing box is rotatably connected to the second sealing cover plate.

[0013] By adopting the above scheme, the first material guide rack is flush with the end of the filter plate (that is, the position of the first fixed bracket is flush). When the filter plate rotates, the raw materials can be sent into the first material guide rack through the inclined surface generated by the filter plate, and the raw materials can be discharged through the second material guide rack. The second sealing plate can limit the first material guide rack. In order to avoid the gap between the filter plate and the first fixed bracket that may cause leakage of the raw materials, the second material guide rack can collect the raw materials. The raw materials in the two material guide racks can be collected by simply opening the second sealing cover plate.

[0014] As a preferred embodiment of the above technical solution, a load-bearing frame is fixedly connected to the inner wall of the compost box corresponding to the end of the filter plate, a flip plate is rotatably connected to the upper top of the load-bearing frame, and the end of the filter plate is located inside the load-bearing frame.

[0015] With the above solution, the load-bearing frame provides solid support for the filter plate, ensuring that the filter plate will not be displaced or deformed due to the weight or vibration of the fertilizer during the composting process, thereby ensuring the stability and safety of the composting process. The filter plate needs to open the flap plate in advance before rotating, and the flap plate is used to protect the end of the filter plate.

[0016] As a preferred embodiment of the above technical solution, the aeration assembly includes a fan fixedly connected to the outer wall of the compost box, the outer wall of the fan is provided with a pressure gauge, the output end of the fan is fixedly connected to a transmission air pipe, the outer wall of the transmission air pipe is provided with a control valve, the outer wall of the compost box is fixedly connected to a pressure regulator, the end of the transmission air pipe is connected to the input end of the pressure regulator, the output end of the pressure regulator is fixedly connected to an exhaust pipe, and the upper top of the exhaust pipe is fixedly connected to a plurality of nozzles.

[0017] With the above solution, the design of the fan, pressure gauge and control valve enables the operator to accurately control the gas flow and pressure entering the composting box, which helps to ensure that the oxygen supply during the composting process is neither excessive nor insufficient, thereby optimizing the composting efficiency. Through the design of the pressure regulator and the exhaust pipe, the gas is evenly distributed to each nozzle before entering the composting box, which can ensure that the composting material can obtain sufficient oxygen supply everywhere, which is conducive to the full decomposition of organic matter and the uniformity of composting.

[0018] As a preferred embodiment of the above technical solution, a sleeve frame is fixedly sleeved on the outer wall of the exhaust pipe, the lower bottom end of the sleeve frame is fixedly connected to the inner bottom end of the compost box, and the outer side wall of the compost box is fixedly connected to a drain pipe for discharging liquid.

[0019] In the above scheme, the use of the sleeve is to provide stable support for the exhaust pipe, thereby enhancing the stability of the entire aeration assembly. Liquid exudate or condensed water will be produced during the composting process. Through the design of the drain pipe, these liquids can be easily discharged out of the composting box to prevent the accumulation of liquid from adversely affecting the composting process.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] In the utility model, by providing a traction component, when in use, the filter plate can be flipped by the flipping component. When the filter plate is flipped at a certain angle and is inclined with the inner bottom end of the compost box, the fertilizer at the inner bottom end of the filter plate can be moved through the inclined edge and gradually moved to the bottom end. Then the fertilizer is discharged to the inside of the sealed box through the second sealing plate, and the fertilizer will also leave the inner top end of the filter plate, so as to achieve the purpose of cleaning the inside of the filter plate. In addition, a second material guide rack is provided to collect the fertilizer in the gap between the end of the filter plate and the first fixed bracket. BRIEF DESCRIPTION OF THE DRAWINGS
