Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically to a spraying and adding device for anti-caking agent in the production of granular fertilizer. Background Technology

[0002] Fertilizer is an essential material for modern agricultural production. To facilitate application, fertilizer is generally processed into granules. During the production process, anti-caking agents need to be added and mixed with granular fertilizer to ensure long-term storage of granular fertilizer.

[0003] When adding anti-caking agents to granular fertilizers, the anti-caking agents are oily liquids. If the anti-caking agents are added directly to the fertilizer, some granular fertilizers may not come into contact with the anti-caking agents, resulting in uneven mixing of the granular fertilizers and the anti-caking agents, which affects the quality of the granular fertilizer processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-caking agent spraying and adding device for granular fertilizer production, which solves the problem that some granular fertilizer may not come into contact with the anti-caking agent, resulting in uneven mixing of the granular fertilizer and the anti-caking agent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying and adding device for an anti-caking agent in granular fertilizer production, comprising a mixing box and a spraying box fixedly connected to the top of the mixing box. A spray pipe is rotatably connected to one side of the inner cavity of the spraying box via a bearing. One end of the spray pipe penetrates the spraying box and extends to the outside of the spraying box. Several nozzles are connected below the surface of the spray pipe and inside the spraying box. A liquid-passing mechanism adapted to the spray pipe is provided at the top of the mixing box. A rotating rod is rotatably connected to one side of the inner cavity of the mixing box via a bearing. One end of the rotating rod penetrates the mixing box and extends to the outside of the mixing box. A motor is fixedly connected to one side of the mixing box via a fixing frame. The machine's output shaft is fixedly connected to one end of a rotating rod extending outside the mixing chamber via a coupling. A first bevel gear is fixedly connected to the surface of the rotating rod. A connecting plate is fixedly connected to one side of the mixing chamber and above the motor. A reciprocating screw is rotatably connected to the bottom of the connecting plate via a bearing. A second bevel gear, compatible with the first bevel gear, is fixedly connected to one end of the reciprocating screw. A threaded sleeve is threaded onto the surface of the reciprocating screw. A sliding groove is provided on one side of the mixing chamber. The interior of the sliding groove is slidably connected to the surface of the threaded sleeve via a slider. A toothed plate is fixedly connected to the rear of the threaded sleeve via a connecting block. A round gear, compatible with the toothed plate, is fixedly connected to the surface of the spray pipe and outside the spray box.

[0006] Preferably, the liquid conveying mechanism includes a liquid pump, which is fixedly installed on one side of the top of the spray box. The liquid outlet of the liquid pump is connected to a liquid outlet pipe, and one end of the liquid outlet pipe is rotatably connected to one end of the spray pipe through a sealed bearing.

[0007] Preferably, the inlet end of the pump is connected to an inlet pipe, and a storage tank is fixedly connected to the other side of the top of the spray box. One end of the inlet pipe passes through the storage tank and extends into the interior of the storage tank.

[0011] Beneficial effects

[0012] This invention provides a spray application device for an anti-caking agent in the production of granular fertilizers. Compared with existing technologies, it has the following advantages:

[0013] (1) This utility model uses a motor to drive a rotating rod to rotate. The rotating rod drives a reciprocating screw to rotate through a first bevel gear and a second bevel gear. The reciprocating screw drives a toothed plate to move up and down through a threaded sleeve. The toothed plate drives the spray pipe to tilt back and forth and swing back and forth through a round gear. This causes the spray pipe to drive multiple nozzles to swing back and forth. The anti-caking agent in the storage tank is drawn into the spray pipe by a pump. The spray pipe sprays the anti-caking agent through multiple nozzles tilting back and forth, so that the anti-caking agent can be evenly sprayed on the fertilizer. This can effectively ensure that the fertilizer is evenly contacted to prevent caking and ensure the quality of fertilizer processing.

[0014] (2) The utility model uses a motor to drive a rotating rod to rotate, which in turn drives two stirring plates to rotate, so that the two stirring plates can stir the granular fertilizer, which can make the fertilizer come into full contact with the anti-caking agent and ensure that the anti-caking agent is evenly coated on the fertilizer.
