Description

Technical Field

[0001] The present application relates to the technical field of magnetized bacterial fertilizer production, and in particular to a magnetized slow-release bacterial fertilizer production device for improving soil microecology and a preparation method thereof. Background Art

[0002] Magnetic fertilizer refers to a fertilizer that is made by mixing magnetic carriers with nitrogen, phosphorus, potassium and trace elements in a certain proportion, granulating them, and maintaining a certain "residual magnetism" after being treated with a magnetic field. The most commonly used magnetic carriers are fly ash, iron ore tailings and steel slag. Magnetic fertilizers mainly affect soil and fruit trees through "residual magnetism". Under equal nutrient conditions, magnetic fertilizers increase production by 5%-15% over ordinary fertilizers. Compared with ordinary compound fertilizers, the good effects of magnetic fertilizers are mainly manifested in the following aspects: (1) Improve the physical properties of the soil: it can reduce soil bulk density, improve soil micro-aggregate structure, increase soil permeability, enhance soil resistance to drought and waterlogging, and increase ground temperature.

[0003] (2) Improve the chemical properties of the soil: it can reduce soil acidity, promote nutrient conversion, increase cation exchange capacity, reduce adsorption of soil phosphate, and increase adsorption of heavy metal ions.

[0004] (3) Promote soil biological activity: It can increase the activity of soil phosphatase, invertase, amylase and hydrogen peroxide. In addition, magnetic fertilizer can also promote germination, growth, improve quality, resist diseases and prevent insects.

[0005] In the magnetization process of magnetized fertilizer production, the fertilizer needs to pass through the magnetization equipment. However, in the process of transporting the fertilizer to the magnetization equipment, there is a phenomenon of fertilizer agglomeration or fertilizer particles being too large, which affects the subsequent magnetization process. Summary of the invention

[0006] In order to at least partially solve the above technical problems, the present application provides a magnetic slow-release fertilizer production device for improving soil microecology and a preparation method thereof.

[0007] In the first aspect, the present application provides a magnetic slow-release fertilizer production device for improving soil microecology, which adopts the following technical solution.

[0008] A magnetized slow-release fertilizer production device for improving soil microecology comprises a frame, characterized in that: it also comprises two magnetized rollers rotatably connected to the frame, the two magnetized rollers rotate relatively, and a gap for fertilizer to pass through is arranged between the two magnetized rollers; a first drive motor, the output shaft of the first drive motor is coaxially connected to one of the magnetized rollers; a first drive gear, two first drive gears are arranged, and the first drive gears are arranged one-to-one with the two magnetized rollers, and the two first drive gears are meshed with each other; a screening component, the screening component is used to screen out agglomerated fertilizers or fertilizers with too large particles; a feed hopper, the feed hopper is installed on the frame and located above the two magnetized rollers, and the feed hopper is also located between the two magnetized rollers; a discharge hopper, the discharge hopper is installed on the frame and located below the two magnetized rollers; a material transport component, the material transport component is used to transport qualified fertilizers screened by the screening component to the feed hopper; a material leveling component, the material leveling component is used to level the fertilizer on the material transport component so that the fertilizer falls into the feed hopper evenly.

[0009] By adopting the above technical solution, the fertilizer enters the material barrel, and then the lumps or large-particle fertilizers are screened out through the screening component, and the qualified fertilizers fall into the transport component and are transported by the transport component. During the transportation process, the fertilizer distribution is made more even by the leveling component, which is beneficial to improve the subsequent magnetization effect. The fertilizer then falls into the feed hopper, and the feed hopper falls between two magnetizing rollers for magnetization, and falls into the discharge hopper after the magnetization is completed.

[0010] Optionally, the screening assembly includes a barrel, which is installed on a frame; a screen, which is installed inside the barrel; a vibration motor, which is installed outside the barrel; and a discharge port is provided at the lower end of the barrel, and the discharge port is arranged in a long strip shape.

[0011] By adopting the above technical solution, when screening materials, the vibration motor continuously vibrates the material barrel, thereby improving the screening efficiency. The discharge port is set in a long strip to reduce the situation where fertilizers fall and pile up together, and reduce the situation where the fertilizer accumulation thickness is too large to affect magnetization.

[0012] Optionally, the material transport component includes a conveyor belt, one end of which is located below the discharge port of the barrel, and the other end of which is located above the feed hopper; and a second drive motor, which drives the conveyor belt to rotate.

[0013] By adopting the above technical solution, the fertilizer falls from the discharge port to the conveyor belt, and the second drive motor drives the conveyor belt to operate, thereby transporting the fertilizer.

[0014] Optionally, the material leveling assembly includes a plurality of material baffle plates, which are arranged above the conveyor belt in parallel with each other and there is a certain gap between the material baffle plates and the conveyor belt, and the length direction of the material baffle plates is perpendicular to the running direction of the conveyor belt; a sliding block, which is slidably connected to the side of the material baffle plate away from the conveyor belt and slides along the length direction of the material baffle plate; a sliding drive component, which is used to drive the sliding block to move; a material leveling sheet, which is arranged in an arc shape with the inner side of the arc facing the direction of fertilizer transportation, and the material leveling sheet is slidably connected to the sliding block, and the sliding block is equipped with a rotating motor, a rack is arranged on one side of the material leveling sheet, and the rotating motor is equipped with a rotating gear, and the rotating gear is meshed with the rack.

[0015] By adopting the above technical solution, when the fertilizer is transported on the conveyor belt, it passes through the material blocking block. If the fertilizer is piled too high, the material blocking block will block the fertilizer with too high a height, so that the thickness of the fertilizer entering between the two magnetizing rollers is kept within a range that can carry out a good magnetization process; while the fertilizer is being transported, the sliding drive member drives the sliding block and the leveling sheet to move back and forth along the length direction of the material blocking block. In the process of moving back and forth, the leveling sheet evenly spreads the fertilizer that is piled too high, and the rotating motor drives the leveling sheet to move, so that the concave side of the leveling sheet always faces the direction in which the fertilizer is transported, which is conducive to spreading the fertilizer evenly, thereby facilitating subsequent magnetization operations.

[0016] Optionally, the sliding drive component includes two pulleys, and the two pulleys are rotatably connected to the two ends of the material baffle plate respectively; a belt, the belt is sleeved on the two pulleys, and the sliding block is fixed to the belt; and a sliding drive motor, the output shaft of the sliding drive motor is coaxially connected to one of the pulleys.

[0017] By adopting the above technical solution, the sliding drive motor rotates forward and reversely to drive the pulley and the belt to rotate forward and reversely, thereby driving the sliding block to slide back and forth along the length direction of the blocking block.

[0018] Optionally, the screen is arranged at an inclination, and the material barrel is provided with a material block outlet at the lowest end after the screen is inclined, the material block outlet is slightly higher than the lowest end of the screen, the material block outlet is connected to a material block channel, the end of the material block channel away from the material block outlet is connected to a crushing barrel, a main shaft is rotatably connected inside the crushing barrel, a number of crushing rods are connected to the side wall of the main shaft, the main shaft is connected to a crushing drive motor, and the crushing drive motor is installed on the crushing barrel.

[0019] By adopting the above technical solution, the inclined setting of the screen is more conducive to the rolling down of agglomerated fertilizers or fertilizers with large particles, and entering the crushing barrel from the material block channel for crushing. The material block outlet is slightly higher than the lowest end of the screen so that the barrel wall can block relatively small fertilizers from entering the material block channel, while agglomerated fertilizers or fertilizers with larger particles can still enter the material block channel.

[0020] Optionally, a discharge pipe is connected to the lower end of the mashing barrel, the other end of the discharge pipe is connected to the barrel, a fan is provided on the discharge pipe, and an electric switch is also provided at the connection between the mashing barrel and the discharge pipe.

[0021] By adopting the above technical scheme, the crushed fertilizer is discharged to the discharge pipe, and then re-enters the material barrel for screening under the agitation of the fan.

[0022] Optionally, it also includes two brush rollers rotatably connected to the frame, the two brush rollers are respectively located on opposite sides of the two magnetized rollers, and the two brush rollers are coaxially fixed with second drive gears at the ends. The frame is rotatably connected to a third drive gear, and the third drive gear is located between the first drive gear and the second drive gear, and is respectively meshed with the first drive gear and the second drive gear.

[0023] By adopting the above technical solution, during magnetization, some fertilizers will adhere to the surface of the magnetizing roller. The rotation direction of the brush roller is the same as that of the magnetizing roller, but the speed of the brush roller is faster than that of the magnetizing roller. The speed difference enables the brush roller to clean the surface of the magnetizing roller and brush the fertilizers attached to the surface of the magnetizing roller into the discharge hopper.

[0024] Optionally, the feed hopper is arranged in a long strip shape, and the length direction is parallel to the axial direction of the magnetization roller.

[0025] By adopting the above technical solution, the feed hopper is arranged in a long strip shape to adapt to the axial direction of the magnetizing roller, thereby achieving a jacquard magnetizing effect.

[0026] In a second aspect, the present application provides a method for preparing a magnetized slow-release bacterial fertilizer for improving soil microecology, comprising the following steps: S1. The fertilizer enters the material barrel, and the vibration motor is started, so that the fertilizer passes through the screen and falls from the discharge port onto the conveyor belt. At the same time, the agglomerated fertilizer or the fertilizer with too large particles cannot pass through the screen, and rolls down along the screen into the material block channel, and enters the crushing barrel from the material block channel; S2, the conveyor belt transports the fertilizer to the magnetized roller. During the transportation process, the baffle plate blocks the fertilizer that is piled too high, so that the fertilizer entering the feed hopper tends to be uniform. At the same time, the sliding block moves back and forth along the baffle plate, and the leveling sheet moves with the sliding block to further spread the fertilizer evenly. When the sliding block moves to the end of the baffle plate, the rotating motor drives the leveling sheet to move, so that the arc-shaped concave side of the leveling sheet is always facing the fertilizer, and at the same time, the crushing rod crushes the fertilizer screened out; S3. The fertilizer is sprinkled from the feed hopper between the two magnetized rollers. The two magnetized rollers rotate to magnetize the fertilizer, and then the magnetized fertilizer falls into the discharge hopper. At the same time, the brush roller brushes the fertilizer attached to the magnetized roller into the discharge hopper, and the crushed fertilizer enters the material barrel again through the discharge pipe.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The fertilizer enters the material barrel, and then the lumps or large particles of fertilizer are screened out by the screening component, and the qualified fertilizer falls into the transport component and is transported by the transport component. During the transportation process, the fertilizer distribution is more evenly distributed through the material leveling component, which is conducive to improving the subsequent magnetization effect. Then the fertilizer falls into the feed hopper, and the feed hopper falls between the two magnetization rollers for magnetization. After the magnetization is completed, it falls into the discharge hopper; 2. When the fertilizer is transported on the conveyor belt, it passes through the blocking block. If the fertilizer is piled too high, the blocking block will block the fertilizer that is too high, so that the thickness of the fertilizer entering between the two magnetizing rollers is kept within a range that can carry out a good magnetization process; while the fertilizer is being transported, the sliding drive member drives the sliding block and the leveling sheet to move back and forth along the length direction of the blocking block. During the back and forth movement, the leveling sheet evenly spreads the fertilizer that is piled too high, and the rotating motor drives the leveling sheet to move, so that the concave side of the leveling sheet always faces the direction from which the fertilizer is transported, which is conducive to evenly spreading the fertilizer, thereby facilitating the subsequent magnetization operation; The inclined setting of the screen is more conducive to the rolling down of agglomerated fertilizers or fertilizers with large particles, and they enter the crushing barrel from the material block channel for crushing. The material block outlet is slightly higher than the lowest end of the screen, so that the barrel wall can block the relatively small fertilizer from entering the material block channel, while agglomerated fertilizers or fertilizers with large particles can still enter the material block channel, and the crushed fertilizer is discharged from the material to the discharge pipe, and then re-enters the material barrel for screening under the agitation of the fan.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-6 The present application is further described with specific embodiments: The embodiment of the present application discloses a device for producing a magnetized slow-release bacterial fertilizer for improving soil microecology. Embodiment 1

[0036] Reference Figure 1 , including a frame 1, two magnetized rollers 2 rotatably connected to the frame 1 through bearings, a feed hopper 3, a discharge hopper 4 located below the magnetized rollers 2, a first drive motor 5 for driving the magnetized rollers 2 to rotate, and a first drive gear 6. The two magnetized rollers 2 rotate relative to each other, and a gap for fertilizer to pass through is provided between the two magnetized rollers 2. The first drive motor 5 is coaxially connected to one of the magnetized rollers 2. There are two first drive gears 6, which are respectively installed at the ends of the two magnetized rollers 2. The first drive motor 5 rotates to drive one magnetized roller 2 to rotate, and the other magnetized roller 2 is driven to rotate synchronously and relatively through the conduction of the first drive gear 6. It also includes two brush rollers 7 rotatably connected to the frame 1 through bearings. The two brush rollers 7 are respectively located on the opposite sides of the two magnetized rollers 2. The two brush rollers 7 are coaxially fixed with second drive gears 8 at their ends. The frame 1 is also rotatably connected to two third drive gears 9 through bearings. The third drive gear 9 is located between the first drive gear 6 and the second drive gear 8, and meshes with the first drive gear 6 and the second drive gear 8 respectively. The first drive motor 5 rotates through the first drive gear 6, the third drive gear 9 and the second drive gear 8 to drive the brush roller 7 to rotate, and the rotation direction of the brush roller 7 is opposite to the rotation direction of the adjacent magnetizing roller 2, so it is convenient to brush off the fertilizer adhering to the magnetizing roller 2.

[0037] Reference Figure 2 , Figure 3 and Figure 4, and also includes a screening component 10, which includes a barrel 101, a screen 102 and a vibration motor 103 installed on the frame 1, the vibration motor 103 is installed on the outer wall of the barrel 101 by screws, the screen 102 is installed inside the barrel 101 by screws, and the screen 102 is arranged at an angle, and the barrel 101 is provided with a block outlet 11 at the lowest end of the inclination of the screen 102, and the block outlet 11 is slightly higher than the lowest end of the screen 102. When screening fertilizers, it is beneficial to screen out agglomerated fertilizers and fertilizers with large particles, and leave the barrel 101 from the block outlet 11. The material block outlet 11 is connected to a material block channel 12, and the end of the material block channel 12 away from the material block outlet 11 is connected to a crushing barrel 13, and a main shaft 14 is rotatably connected to the crushing barrel 13 through a bearing, and a number of crushing rods 15 are evenly fixed on the side wall of the main shaft 14. A crushing drive motor 16 is fixed to the upper end of the crushing barrel 13 through screws, and the output shaft of the crushing drive motor 16 is coaxially connected to the main shaft 14. When screening fertilizers, the vibration motor 103 makes the material barrel 101 and the screen 102 vibrate, so that the finer fertilizers fall quickly, while the lumps or larger particles of fertilizers enter the crushing barrel 13 from the material block channel 12 for crushing. The lower end of the crushing barrel 13 is provided with an electric switch and is connected to a discharge pipe 17. The other end of the discharge pipe 17 is connected to the material barrel 101. A fan 18 is installed on the discharge pipe 17. After the crushing barrel 13 crushes the fertilizer with lumps or large particles, the electric switch and the fan 18 are turned on, so that the crushed fertilizer returns to the material barrel 101 for screening again.

[0038] Reference Figure 1 and Figure 2 The lower end of the barrel 101 is provided with a discharge port, and the discharge port is arranged in a long strip shape, and an inclined surface is arranged between the discharge port and the barrel body, so that the fertilizer is in a relatively uniform state after falling, and will not be piled up in large quantities. It also includes a material transport component 19, which includes a conveyor belt 191 and a second drive motor 192 for driving the conveyor belt 191 to run. One end of the conveyor belt 191 is located below the discharge port of the barrel 101, and the other end is located above the feed hopper 3. The feed hopper 3 is arranged in a long strip shape, and the length direction is parallel to the axial direction of the magnetizing roller 2, which is conducive to evenly spreading the fertilizer between the two magnetizing rollers 2. The axial direction of the magnetizing roller 2 is perpendicular to the running direction of the conveyor belt 191. The fertilizer falls from the discharge port of the barrel 101 to the surface of the conveyor belt 191, and then is transported by the conveyor belt 191 to fall into the feed hopper 3, and falls between the two magnetizing rollers 2 through the feed hopper 3 for magnetization.

[0039] Reference Figure 4 and Figure 5, and also includes a material leveling assembly 20, which includes two baffle plates 201, a sliding block 202, a sliding drive 203 and a material leveling sheet 204. The two baffle plates 201 are fixed to the frame 1 by screws in a front-to-rear manner. The baffle block is located above the conveyor belt 191, and there is a certain gap between the lower surface of the baffle block and the upper surface of the conveyor belt 191 for fertilizer to pass through. The length direction of the baffle block is perpendicular to the running direction of the conveyor belt 191. When the conveyor belt 191 transports fertilizer, it passes through the baffle block. If the fertilizer is piled too high, it will be blocked by the baffle block, so that when the fertilizer is magnetized, the magnetization effect will not be affected by excessive accumulation. The sliding block 202 is slidably connected to the side of the baffle block away from the conveyor belt 191, and slides along the length direction of the baffle plate 201. The sliding drive component 203 includes two pulleys 2031, a belt 2032 and a sliding drive motor 2033. The two pulleys 2031 are rotatably connected to the two ends of the material blocking plate 201 respectively. The belt 2032 is sleeved on the two pulleys 2031. The sliding block 202 is fixed to the belt 2032 by screws. The output shaft of the sliding drive motor 2033 is coaxially connected to one of the pulleys 2031, so that the sliding drive motor 2033 rotates forward and reverse, and drives the sliding block 202 to slide back and forth along the material blocking block through the conduction of the pulleys 2031 and the belt 2032.

[0040] The material leveling piece 204 is arranged in an arc shape, and the inner side of the arc is arranged toward the direction in which the fertilizer is transported. The lower end of the material leveling piece 204 is flush with the lower end of the blocking block. The sliding block 202 is provided with an arc groove adapted to the material leveling piece 204. The material leveling piece 204 is slidingly connected to the sliding block 202 through the arc groove. A rotating motor 21 is installed on the sliding block 202 by screws. A rotating gear 22 is coaxially fixed to the output shaft of the rotating motor 21. A rack 23 is provided on the side wall of the material leveling piece 204, and the rack 23 is meshed with the rotating gear 22. The sliding block 202 drives the material leveling piece 204 to move back and forth along the length direction of the material blocking block, and continuously adjusts the stacking height of the fertilizer, so that the fertilizer is more evenly spread on the conveyor belt 191. When the sliding block 202 moves to the end of the material blocking block, the rotating motor 21 starts to drive the material leveling piece 204 to rotate through the transmission of the rotating gear 22 and the rack 23, so that the concave side of the material leveling piece 204 always faces the fertilizer, which is convenient for leveling the fertilizer.

[0041] A method for preparing a magnetized slow-release bacterial fertilizer for improving soil microecology comprises the following steps: S1, the fertilizer enters the material barrel 101, and the vibration motor 103 is started, so that the material barrel 101 vibrates, so that the fertilizer can pass through the screen 102 more easily and fall from the discharge port to the conveyor belt 191. At the same time, the agglomerated fertilizer or the fertilizer with too large particles cannot pass through the screen 102, and rolls down along the screen 102 into the material block channel 12, and enters the crushing barrel 13 from the material block channel 12; S2, the conveyor belt 191 transports the fertilizer to the magnetized roller 2. During the transportation process, the baffle plate 201 blocks the fertilizer that is piled too high, so that the fertilizer entering the feed hopper 3 tends to be uniform. At the same time, the sliding block 202 moves back and forth along the baffle plate 201, and the leveling sheet 204 moves with the sliding block 202 to further spread the fertilizer evenly. When the sliding block 202 moves to the end of the baffle plate 201, the rotating motor 21 drives the leveling sheet 204 to move, so that the arc-shaped concave side of the leveling sheet 204 is always facing the fertilizer, and at the same time, the crushing rod 15 crushes the fertilizer screened out; S3. The fertilizer is sprinkled from the feed hopper 3 between the two magnetized rollers 2. The two magnetized rollers 2 rotate to magnetize the fertilizer, and then the magnetized fertilizer falls into the discharge hopper 4. At the same time, the brush roller 7 brushes the fertilizer attached to the magnetized roller 2 into the discharge hopper 4, and the crushed fertilizer enters the material barrel 101 again from the discharge pipe 17 through the fan 18. Embodiment 2

[0042] The difference from the first embodiment is that a first pulley 24 and a second pulley 25 are rotatably connected in the sliding block 202 via a rotating shaft, the surface of the first pulley 24 is in contact with the surface of the second pulley 25 and there is a certain pressure, and the second pulley 25 is coaxially connected to the rotating gear 22, so the rotation of the first pulley 24 drives the second pulley 25 to rotate, thereby driving the rotating gear 22 to rotate. The frame 1 is welded with abutment rods 26 on one side of the sliding block 202 by screws, and the frame 1 is slidingly connected with abutment rods 26 on both sides. The abutment rods 26 can slide in the horizontal direction, and the sliding block 202 is provided with a channel for the abutment rod 26 to be inserted and passed. When the sliding block 202 is close to the abutment rod 26 on one side, the abutment rod 26 is inserted into the channel, and one side wall of the abutment rod 26 abuts against the surface of the first pulley 24. Therefore, when the sliding block 202 moves toward the abutment rod 26 on one side of the frame 1, the first pulley 24 rotates due to the abutment with the abutment rod 26, thereby driving the second pulley 25 and the rotating gear 22 to rotate, thereby driving the material leveling sheet 204 to move. The sliding block 202 is also slidably connected with a moving block 27 inside. A guide arc surface is provided inside the moving block 27. A magnet 28 is installed on the innermost side of the guide arc surface. An iron block 29 is fixed to the top of the abutment rod 26. When the sliding block 202 approaches the edge of the frame 1, the iron block 29 approaches the magnet 28 through the guidance of the guide arc surface and is adsorbed by the magnet 28. At this time, the abutment rod 26 is away from the first pulley 24 due to the guidance of the guide arc surface, thereby no longer driving the first pulley 24 to rotate. Then the sliding block 202 moves in the opposite direction. At this time, the moving block 27 slides inside the sliding block 202 due to being adsorbed with the abutment rod 26, and finally abuts against the inner side wall of the sliding block 202, resulting in separation from the abutment rod 26. A spring 30 is fixed between the abutment rod 26 and the frame 1. After the abutment rod 26 is separated from the sliding block 27, the spring 30 pushes the abutment rod 26 back to its original position.

[0043] The implementation principle of the embodiment of the present application is as follows: the fertilizer is screened by the screen 102 in the material barrel 101, and the fertilizer with smaller particles falls onto the conveyor belt 191, while the fertilizer with lumps or larger particles is screened out and enters the crushing barrel 13 for crushing, and enters the material barrel 101 again after the crushing is completed; when the fertilizer on the conveyor belt 191 passes through the baffle plate 201 and the leveling sheet 204, it is evenly laid on the surface of the conveyor belt 191, and then falls from the feed hopper 3 between the two magnetizing rollers 2 for magnetization, and the uniform fertilizer can improve the magnetization effect.

[0044] It should be noted that the above embodiments are only used to illustrate the present application and are not intended to limit the technical solutions described in the present application. Although the present application has been described in detail in this specification with reference to the above embodiments, a person of ordinary skill in the art should understand that a person of ordinary skill in the art can still modify or make equivalent substitutions to the present application, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present application should be included in the scope of the claims of the present application.
