Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilizer preparation equipment, and in particular to a water-soluble fertilizer preparation device. Background Technology

[0002] Water-soluble fertilizers are highly efficient compound fertilizers that dissolve completely in water and contain no poorly soluble impurities. They are typically made from a scientifically balanced blend of macro- and micro-elements. Water-soluble fertilizers can be applied precisely through irrigation systems, representing an important direction for the intensive and intelligent development of modern agriculture.

[0003] During fertilizer transportation and storage, the fertilizer is often compressed and stacked, inevitably generating fertilizer powder. When this fertilizer enters the mixing equipment, the drop height between the discharge port and the conveyor belt causes the powder to easily form dust, which is then dispersed into the surrounding work environment. This not only poses a threat to the health of operators, but the dispersed fertilizer powder also adheres to the equipment in the production workshop, making it difficult to clean and polluting the work environment. In addition, during continuous operation, the surface of the conveyor belt generates static electricity, which attracts the powdered fertilizer, causing the powder to continuously adhere to the conveyor belt. Over time, the adhered powder gradually accumulates, making the surface of the conveyor belt uneven, affecting the stability and accuracy of fertilizer transportation, and thus interfering with the precision of the overall fertilizer mixing ratio. Furthermore, the unevenness of the conveyor belt surface increases friction with the drive unit, idlers, and other components, increasing equipment wear and reducing the service life of the conveyor belt.

[0004] Secondly, cleaning the mixing tank is crucial after each batch of fertilizer is prepared. However, current cleaning methods mainly rely on manual operation. Manual cleaning is not only labor-intensive and time-consuming, but also inefficient, and it is difficult to guarantee the thoroughness and completeness of the cleaning. Especially when producing different types of fertilizers, if there are residues from the previous batch in the mixing tank, these residues may cross-contaminate with subsequent batches, altering the fertilizer's composition and proportions, and seriously affecting the quality and performance of later batches.

[0005] Therefore, it is necessary to provide a new water-soluble fertilizer formulation device to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a water-soluble fertilizer preparation device.

[0007] The water-soluble fertilizer preparation device provided by this utility model includes: a mixing cylinder, a hopper, a cleaning roller, a cleaning component, a first dust suction nozzle, a water storage tank, and a cleaning mechanism. A belt conveyor is provided on one side of the mixing cylinder, and hoppers are equidistantly located above one side of the belt conveyor. A conveyor belt is provided below each hopper, and a cleaning roller is installed at the bottom of each conveyor belt. The outer wall of the cleaning roller is provided with soft bristles. A cleaning component is installed between the conveyor belt and the cleaning roller. The cleaning component drives the cleaning roller to rotate and clean the fertilizer dust adhering to the conveyor belt. A first dust suction nozzle is provided on one side of each cleaning roller, and a second dust suction nozzle is equidistantly installed on the side of the belt conveyor away from the cleaning roller. A water storage tank is provided on one side of the mixing cylinder, and a cleaning mechanism is installed between the mixing cylinder and the water storage tank. The cleaning mechanism is used to clean the inside of the mixing cylinder.

[0008] Preferably, the cleaning assembly includes: a drive pulley, a driven pulley, and a transmission rod. A drive pulley is fixedly connected to the rotating shaft end of one end of the conveyor belt. A transmission rod is rotatably connected inside the bottom support frame of the conveyor belt. The outer wall of the transmission rod is slidably connected to the inner wall of the cleaning roller. A driven pulley is fixedly connected to the end of the transmission rod near the drive pulley. The drive pulley and the driven pulley are connected by belt drive. The outer wall of the transmission rod is provided with equidistant protrusions. The inner wall of the cleaning roller is provided with mounting grooves corresponding to the protrusions.

[0009] Preferably, the bottom support frame of the conveyor belt is rotatably connected to a reciprocating screw, which is connected to the corresponding transmission rod via a belt drive. A slider is installed in the middle of the reciprocating screw, and one end of the slider is rotatably connected to the cleaning roller.

[0010] Preferably, the cleaning assembly includes: a nozzle, an adapter, and a water pump. A hollow stirring rod is rotatably connected inside the stirring tank. The outer wall of the stirring rod is equidistantly connected to nozzles. An adapter is rotatably connected to the top of the stirring rod. A water pipe is fixedly connected to the other end of the adapter. The other end of the water pipe is connected to the water pump. The bottom of the water pump is fixedly connected to the top of the water storage tank. The other end of the water pump is connected to the water storage tank through a pipe.

[0011] Preferably, a motor is fixedly connected to the top of the mixing tank, a worm is fixedly connected to the output end of the motor, and a worm wheel is fixedly connected to the top of the mixing rod, with the worm wheel meshing with the worm.

[0012] Preferably, a collection box is provided on the side of the belt conveyor near the second dust suction nozzle, and a fan is connected to one side of the collection box through an air duct. One end of both the first and second dust suction nozzles is connected to the input end of the fan through an air duct.

[0013] Preferably, the top of the collection box has an air outlet, and a filter is fixedly connected to the collection box near the air outlet.

[0014] Preferably, the orientations of the several groups of nozzles are all different.

[0015] Compared with related technologies, the water-soluble fertilizer preparation device provided by this utility model has the following beneficial effects:

[0016] The coordinated operation of the cleaning rollers and cleaning components effectively removes fertilizer dust adhering to the conveyor belt, preventing equipment wear caused by dust adhesion. Simultaneously, the first and second suction nozzles, driven by the fan, promptly collect the cleaned dust and dust generated during material feeding into the collection box, significantly reducing the dispersion of fertilizer powder into the working environment, protecting the health of operators, lowering workshop cleaning and maintenance costs, and effectively improving the working environment. Because the amount of fertilizer powder adhering to workshop equipment surfaces is reduced, other equipment in the production workshop does not require frequent cleaning, reducing the manpower, resources, and time spent on equipment cleaning and improving overall production efficiency.

[0017] The cleaning roller, through the combined action of the driving pulley, driven pulley, transmission rod, reciprocating screw, and slider, achieves comprehensive and efficient cleaning of the conveyor belt. This ensures that the surface of the conveyor belt remains relatively flat, avoiding surface unevenness caused by powder adhesion and accumulation. It guarantees the stability and accuracy of fertilizer granules during the conveying process, thus providing a guarantee for precise fertilizer formulation ratios and improving the formulation accuracy of water-soluble fertilizers.

[0018] The cleaning mechanism uses a motor-driven worm gear and worm wheel to rotate the stirring rod. Simultaneously, a water pump delivers water from the storage tank to the stirring rod via an adapter and water pipes. High-pressure water jets are then sprayed out from nozzles on the outer wall facing different directions. Compared to traditional manual cleaning, this automated cleaning method significantly improves cleaning efficiency and saves labor and time costs. The rotation of the stirring rod, combined with the nozzles facing different directions, ensures that the high-pressure water jets can cover every corner of the mixing cylinder's inner wall, achieving a comprehensive and deep cleaning of the cylinder's interior. This effectively solves the problem of traditional manual cleaning failing to guarantee thoroughness and completeness, reduces the risk of cross-contamination between different batches of fertilizer, and ensures the quality and performance of subsequent batches of fertilizer.

An air outlet is opened on the top of the collection box 21. A filter 23 is fixedly connected to the collection box 21 near the air outlet.

[0029] It should be noted that the outer diameter of the driving pulley 9 is larger than that of the driven pulley 10, which makes the rotation speed of the cleaning roller 5 greater than that of the conveyor belt 4. The transmission rod 11 and the reciprocating screw 12 are connected by belt drive, and the two rotate at the same speed.

[0030] Please see Figure 5 and Figure 6The cleaning assembly includes: nozzles 15, adapters 16, and a water pump 17. A hollow stirring rod 14 is rotatably connected inside the stirring cylinder 1.

[0031] It should be noted that: one side of the mixing tank 1 is connected to an air inlet. After the inner wall of the mixing tank 1 is cleaned, the air pipe of the blower 22 is connected to the air inlet to accelerate the drying of the inner wall of the mixing tank 1. One end of the air inlet is equipped with a one-way valve, which can be automatically opened when blowing air in and automatically closed when cleaning and mixing fertilizer.

[0032] The working principle of the water-soluble fertilizer preparation device provided by this utility model is as follows.

[0033] Material preparation for silo 3: According to the formula requirements of different fertilizers, the operator puts various fertilizers into the corresponding silo 3. Each silo 3 is equipped with a conveyor belt 4. Through a pre-set control program, the feeding speed of silo 3 and the running speed of conveyor belt 4 are precisely adjusted according to the specific fertilizer formula ratio to ensure that different fertilizers can be delivered to the subsequent stages in a precise ratio.

[0034] Conveyor belt 4 cleaning synchronous start: At the same time as the conveyor belt 4 starts running, the drive pulley 9 fixedly connected to one end of its rotating shaft rotates synchronously; the drive pulley 9 is connected to the driven pulley 10 through a belt, and the driven pulley 10 is installed at the end of the transmission rod 11 near the drive pulley 9, thereby driving the transmission rod 11 to rotate; the outer wall of the transmission rod 11 is slidably connected to the inner wall of the cleaning roller 5, and the protrusions on the outer wall of the transmission rod 11 cooperate with the corresponding mounting grooves opened on the inner wall of the cleaning roller 5, so that the cleaning roller 5 starts to rotate under the drive of the transmission rod 11; At the same time, the transmission rod 11 is also connected to the reciprocating screw 12 via a belt, causing the reciprocating screw 12 to start rotating. Since the slider 13 is installed in the middle of the reciprocating screw 12 and one end of the slider 13 is rotatably connected to the cleaning roller 5, the cleaning roller 5 will also reciprocate along the axial direction of the reciprocating screw 12 while rotating with the transmission rod 11. The rotating and reciprocating cleaning roller 5, with the soft bristles on its outer wall, performs a comprehensive and efficient cleaning of the surface of the conveyor belt 4, removing the fertilizer dust adhering to the conveyor belt 4.

[0035] Dust collection: When the blower 22 starts working, under the suction force generated by the blower 22, the first dust suction nozzle 6 on one side of the cleaning roller 5 sucks away the cleaned fertilizer powder through the air duct. This powder eventually enters the collection box 21 along the air duct. At the same time, during the operation of the conveyor belt 4, the powder generated by the gravity of the fertilizer particles is sucked away by the second dust suction nozzle 7 installed at equal intervals on the side of the belt conveyor 2 away from the cleaning roller 5, and is also transported to the collection box 21 through the air duct. The top of the collection box 21 has an air outlet, and a filter 23 is fixedly connected near the air outlet to ensure that the collected powder is effectively trapped in the collection box 21 and prevented from escaping back into the working environment.

[0036] Fertilizer is transported to mixing tank 1: conveyor belt 4 runs continuously, transporting the fertilizer on the surface to belt conveyor 2; belt conveyor 2 then transports fertilizers of different proportions to mixing tank 1, ready for mixing and preparation.

[0037] Fertilizer mixing and preparation: When fertilizers of different proportions are conveyed to mixing tank 1 by belt conveyor 2, the stirring device inside mixing tank 1 starts to work, fully mixing the fertilizers to make them uniformly blended, thus completing the preparation process of water-soluble fertilizers; the mixed fertilizers are discharged through the discharge port at the bottom of mixing tank 1 for subsequent packaging and other processes.

[0038] Cleaning of mixing tank 1: After a batch of fertilizer is prepared, the inside of mixing tank 1 needs to be cleaned. At this time, the motor 18 is started, and the worm gear 19 fixedly connected to the output end of the motor 18 rotates accordingly. Since the worm gear 19 meshes with the worm wheel 20 fixedly connected to the top of the mixing rod 14, the mixing rod 14 starts to rotate under the drive of the worm gear 19.

[0039] High-pressure water spray cleaning: At the same time, water pump 17 is started; water pump 17 draws water from water storage tank 8 and delivers it to the interior of stirring rod 14 through water pipe; stirring rod 14 has a hollow structure, and its outer wall is equidistantly connected with nozzles 15, and the orientation of several sets of nozzles 15 is different; under the action of water pump 17, water forms a high-pressure water flow in stirring rod 14 and is sprayed to various corners of the inner wall of stirring tank 1 through nozzles 15; the rotating stirring rod 14 allows nozzles 15 to cover different positions of the inner wall of stirring tank 1, and works with high-pressure water flow to deeply clean the inner wall of stirring tank 1.

[0040] Waste discharge and drying: The waste material after washing is discharged through the discharge port at the bottom of the mixing tank 1; after washing, the inside of the mixing tank 1 is dried by blower 22 to ensure that the inside of the mixing tank 1 is dry and clean before the next batch of fertilizer is prepared.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
