Description

Technical Field

[0001] This utility model relates to the technical field of microbial fertilizer production equipment, specifically a screening device for compound microbial fertilizer production. Background Technology

[0002] Microbial fertilizers, also known as bio-fertilizers, rely on living microorganisms to provide or improve plant nutrition, thereby increasing agricultural yield or improving quality. Screening is a crucial step in the production of microbial fertilizers, helping to remove impurities from raw materials and ensuring the purity and quality of the final product. Microorganisms in liquid fertilizers, such as nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, and potassium-solubilizing bacteria, play an important role in plant growth and soil fertility. Therefore, special care must be taken to protect the activity of these microorganisms during screening. The main purpose of liquid fertilizer screening is to remove large particulate impurities from the raw materials, ensuring product uniformity and quality. Since some components in fertilizers may be corrosive to the screening equipment materials, the equipment needs to be cleaned after use. Traditional cleaning methods may rely heavily on manual labor, which is not only inefficient but also increases labor costs. Therefore, we provide a screening device for compound microbial fertilizer production to solve these problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a screening device for compound microbial fertilizer production, comprising a support platform, a cleaning component for conveying cleaning agent to facilitate cleaning of the screening device, a discharge component for extracting bio-fertilizer, a screening component for screening the bio-fertilizer, a screening box mounted on the upper surface of the support platform, a motor mounted on the bottom surface of the screening component, the output end of the motor penetrating the support platform and extending into the interior of the screening box, a rotating rod fixed to the output end of the motor, a scraper mounted on the outer surface of the rotating rod, a pump body A mounted on the upper surface of the support platform, a water pumping pipe connected to the input end of the pump body A, a water delivery pipe connected to the output end of the pump body A, and a plurality of nozzles connected to the end of the water delivery pipe away from the pump body A after penetrating the screening box.

[0005] The top of the rotating rod is fixed with a screening cylinder, the inner bottom wall of the screening cylinder is fixed with an electric telescopic rod, and the output end of the electric telescopic rod is equipped with a push plate.

[0006] The outer surface of the pusher plate is slidably connected to the inner wall of the screening cylinder, the outer surface of the screening cylinder has multiple screen holes, and the outer surface of the screening cylinder is equipped with multiple vertical plates.

[0007] The discharge assembly includes a pump body B fixed on the upper surface of a support platform, and the output end of the pump body B is connected to an output pipe.

[0008] The pump body B has an input pipe connected to its input end, and the end of the input pipe away from the pump body B is connected to the outer surface of the screening box.

[0009] The screening box has a feed inlet on its upper surface and a sealing cover on its upper surface.

[0010] The support platform has four support legs fixed to its bottom surface, and each support leg is equipped with a caster wheel at its bottom end. A controller is installed on the upper surface of the support platform.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a pump body A to drive a water extraction pipe to draw in cleaning agent, which is then sprayed into the screening box through a water delivery pipe and nozzle. This allows for rapid delivery of the cleaning agent, improving cleaning efficiency. The motor-driven rotating screening cylinder can more effectively contact the cleaning agent during the cleaning process, ensuring that the surface of the screening cylinder is thoroughly cleaned and removing residual fertilizer and impurities. At the same time, the rotating rod drives the scraper to rotate, and the scraper can evenly contact the inner wall of the screening box during rotation, effectively cleaning residual fertilizer and impurities adhering to the inner wall and avoiding cleaning dead corners. This not only improves the cleaning efficiency of the screening box but also helps protect the equipment and reduce maintenance costs. Attached Figure Description

The input end of pump body A102 is connected to a water pumping pipe 101. The output end of pump body A102 is connected to a water supply pipe 103. The end of water supply pipe 103 away from pump body A102 passes through the screening box 5 and is connected to multiple nozzles 104.

[0024] The top of the rotating rod 302 is fixed with a screening cylinder 305, and the bottom wall of the screening cylinder 305 is fixed with an electric telescopic rod 303.
