Description

Technical Field

[0001] The invention relates to the technical field of quantitative weighing, in particular to a raw material quantitative weighing device for a composite microbial fertilizer production line. Background Art

[0002] The unreasonable application method of chemical fertilizers will cause the accumulation of a large number of elements, which can easily lead to soil compaction and worsening soil aeration. Therefore, in the production process of modern compound microbial fertilizers, various bacterial agents and raw materials need to be accurately mixed and prepared, and quantitative weighing devices are usually used for metering and weighing.

[0003] The patent with patent announcement number CN205240507U discloses a raw material quantitative weighing device for a composite microbial fertilizer production line, which includes a frame, an active roller and a driven roller are arranged at both ends of the frame, the active roller is connected to a transmission motor, a transmission belt is surrounded by the active roller and the driven roller, and annular constraint strips are arranged on both sides of the surface of the transmission belt, a weighing roller is arranged in the middle of the frame, a material guide frame is arranged on both sides of the end of one end of the frame, a strip hole is arranged horizontally in the middle of the material guide frame, a material guide plate is arranged between the material guide frames, fixed sliders are arranged on both sides of the upper part of the material guide plate, the fixed slider on the upper end of the material guide plate is connected with a spring, and belt tensioning frames are arranged on both sides of the lower part of the frame, and the belt tensioning frame is hinged with an L-shaped adjusting rod, and one end of the adjusting rod is connected to a tensioning device through a steel wire. It has the advantages of simple structure, reasonable design, accurate measurement, automatic adjustment of belt tightness, prevention of raw material leakage, and ability to prevent material adhesion on the belt.

[0004] However, the device still has some shortcomings: the device can weigh and transport fertilizers, but the fertilizers are easily deviated from the center of the conveyor belt during the transportation process, causing the fertilizers to be too dispersed on the top of the conveyor belt, so that the gravity pressure from the fertilizers on the weighing component is relatively dispersed, making it difficult for the weighing component to effectively weigh the dispersed fertilizers, thereby reducing the accuracy of the weighing results, and thus affecting the overall ratio of the fertilizers. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a raw material quantitative weighing device for a composite microbial fertilizer production line, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a quantitative weighing device for raw materials of a composite microbial fertilizer production line, comprising a base, vertical plates are arranged at the corners of the top of the base, a transmission roller is rotatably installed on the inner wall of the vertical plate, and a driving component is built into the transmission roller, a conveyor belt is transmission-installed on the outer wall of the transmission roller, a U-shaped support plate is arranged on the periphery of the base, and a motor is arranged on the outer wall of the U-shaped support plate, a square groove is opened inside the U-shaped support plate, a weighing component is arranged on the top of the U-shaped support plate, and the top of the weighing component is in contact with the top of the inner wall of the conveyor belt; above the U-shaped support plate An anti-dispersion device is provided for causing the fertilizer to be centered on the top of the conveyor belt, an anti-softening device is provided on the inner side of the U-shaped support plate for preventing the conveyor belt from weakening its own tension due to long-term use, and an anti-residue device is provided on the inner side of the anti-softening device for preventing residual fertilizer powder from adhering to the conveyor belt; the anti-dispersion device includes a reciprocating screw rod, one end of which is fixedly installed at the output end of the motor away from the center of the base, the outer wall of the reciprocating screw rod movably passes through the interior of the U-shaped support plate, the reciprocating spiral groove on the outer wall of the reciprocating screw rod is threadedly connected with an L-shaped push plate, and the outer walls on both sides of the L-shaped push plate are slidably installed on the U-shaped support plate Inside the square groove of the support plate, a brush plate is fixedly installed on the top of the L-shaped push plate near the center of the base, a rotating wheel is rotatably installed on the inner wall of the U-shaped groove of the brush plate, a brush plate assembly is fixedly installed on the inner wall of the rotating wheel, a swing plate is hinged on the right side of the top of the U-shaped support plate through a torsion spring, a plurality of hollow vibrating plates are equidistantly and fixedly installed on the top of the L-shaped push plate, a U-shaped protective shell is fixedly installed at the top edge of the U-shaped support plate, an arc block is fixedly installed on the top of the inner wall of the U-shaped protective shell, the transmission roller rotates through its own built-in driving assembly and drives the conveyor belt to perform fertilizer transmission work, and the conveyor belt transports the fertilizer from the external equipment The raw materials are transported in proportion. When the raw materials are laid flat on the top of the conveyor belt, downward gravity is generated. When the load-bearing starts, the other equipment stops operating. At this time, the gross weight of the conveyor belt is removed by the weighing component to weigh the raw materials and record the data. Before the raw material transportation starts, the motor on the outer wall of the U-shaped support plate is started. When the output end of the motor rotates, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, the reciprocating spiral groove on its outer wall restricts the inner wall of the L-shaped push plate, so that the reciprocating screw can drive the L-shaped push plate to slide along the inner wall of the square groove of the U-shaped support plate toward the center of the base, and the L-shaped push plate drives the brush plate to slide synchronously along the top of the conveyor belt;When the brush plate moves toward the center of the base, it drives the wheel to move synchronously. The outer wall of the wheel contacts the top of the inner wall of the U-shaped protective shell to generate friction and start to rotate. The wheel drives the brush plate assembly to rotate and brush along the top of the inner wall of the U-shaped protective shell toward the center of the base. The raw material powder attached to the top of the inner wall of the U-shaped protective shell is brushed away by the brush plate assembly and falls to the top of the conveyor belt. At the same time, when the L-shaped push plate moves toward the center of the base, it loses its resistance to the swing plate. The swing plate causes the hinge shaft between itself and the U-shaped support plate to start rotating through the elastic force of the torsion spring, causing the swing plate to swing toward the center of the conveyor belt. On the contrary, the swing plate moves away from the center of the conveyor belt. After that, when the L-shaped push plate drives the hollow vibration plate to move toward the center of the base, the hollow vibration plate contacts the arc block to generate resistance. The hollow vibration plate is bent and deformed by the resistance. When the hollow vibration plate passes over the arc block, it will swing back and forth to generate vibration during its own toughness reset process. ;

[0007] According to the above technical solution, the bottom of the brush plate contacts the top of the conveyor belt, and a U-shaped groove is provided on the top of the brush plate. The outer wall of the swing plate is located on the right side movement trajectory of the brush plate. The top of the inner wall of the U-shaped protective shell contacts the outer wall of the rotor, and the arc surface of the outer wall of the arc block is located on the movement trajectory of the hollow vibration plate.

[0008] The U-shaped frame is located inside the trapezoidal frame, and the outer wall of the resistance plate is vertically slidably installed in the inside of the U-shaped frame slide groove by a spring, and the flat plate provides limit support for the trapezoidal frame. When the L-shaped push plate pushes the trapezoidal frame to slide along the top of the flat plate toward the center of the base, the inclined surface of the trapezoidal frame will resist the bottom arc surface of the resistance plate inside the U-shaped frame. At this time, the resistance plate generates an upward force and slides upward along the inner wall of the U-shaped frame slide groove, causing the top of the resistance plate to resist the bottom surface of the conveyor belt and deform and stretch upward, and then the resistance plate is reset by the spring force.

[0009] According to the above technical solution, the outer wall of the trapezoidal frame is located on the movement trajectory of the inner wall of the L-shaped push plate, a slide groove is opened on the top of the U-shaped frame, the bottom arc surface of the resistance plate is located on the movement trajectory of the trapezoidal frame, and the top of the resistance plate contacts the bottom of the conveyor belt.

[0010] The outer wall of the heat conducting plate is fixedly mounted inside the trapezoidal frame, and the bottom of the heat conducting plate is slidably mounted on the top of the flat plate by a spring. The outer wall of the heat conducting plate is located on the movement trajectory of the trapezoidal frame, and the side of the wave plate away from the center of the base is slidably mounted on the edge of the side of the heat conducting plate close to the center of the base by a spring. The bottom of the resistance block is fixedly mounted on the top of the flat plate, and the top arc surface of the resistance block is located on the movement trajectory of the wave plate. After the side of the trapezoidal frame close to the center of the base passes over the resistance plate, it will resist the heat conducting plate from moving along the top of the flat plate toward the center of the base. The trapezoidal frame drives the heating component to move synchronously, and the heat dissipated by the heating component is absorbed and diffused by sliding on the heat conducting plate. When the heat conducting plate slides, it drives the wave plate to move synchronously. When the wave plate moves toward the center of the base, its own arc surface is resisted by the resistance block. The wave plate is guided by its own arc surface to slide upward along the inner wall of the wave plate and reset by the spring, and this process repeats.

[0011] According to the above technical scheme, the anti-residue device includes a sliding plate, a negative pressure fan assembly and an I-shaped column. The bottom of the sliding plate is slidably installed on the top of the flat plate, and a limiting groove is provided inside the sliding plate. The outer wall of the sliding plate is located on the movement trajectory of the inner wall of the heat conducting plate. The bottom of the negative pressure fan assembly is fixedly installed on the top of the sliding plate. The I-shaped column is rotatably installed on the inner wall of the sliding plate limiting groove near one end of the negative pressure fan assembly. The outer wall of the I-shaped column contacts the top of the flat plate. When the heat conducting plate moves toward the center of the base, it pushes the sliding plate to slide synchronously along the top of the flat plate. The sliding plate drives the negative pressure fan assembly to move synchronously, and the sliding plate drives the I-shaped column to slide synchronously along the top of the flat plate to generate a rotational force and start to rotate. The I-shaped column converts the sliding friction between the sliding plate and the flat plate into rolling friction.

[0012] The bottom of the guide plate is hinged on the side of the negative pressure fan assembly near the center of the base, and the I-shaped column drives the cylinder to move along the negative pressure fan assembly through the transmission belt. The outer wall of the vacuum fan assembly rotates, and the cylinder drives the cam to rotate, and the cam will resist the sliding column to generate an upward force. At this time, the sliding column slides upward along the outer wall of the negative pressure fan assembly. The sliding column ensures that it can always be close to the outer wall of the cam through the setting of the spring between itself and the negative pressure fan assembly. In the process of the sliding column driving the U-shaped column to move upward, the U-shaped column will resist the outer wall of the guide plate, causing the hinge shaft between the bottom of the guide plate and the side of the negative pressure fan assembly close to the center of the base to start rotating. At this time, the guide plate rotates in an arc shape with the hinge shaft as the axis toward the negative pressure fan assembly, and then the guide plate resets itself through the torsion spring, and repeats this process.

[0013] According to the above technical solution, the outer wall of the cylinder is transmission-connected to the top of the inner wall of the transmission belt, the outer wall of the sliding column contacts the arc surface of the outer wall of the cam, and the outer wall of the guide plate contacts the inner wall of the sliding column.

[0014] The present invention provides a raw material quantitative weighing device for a composite microbial fertilizer production line, which has the following beneficial effects: (1) The present invention adopts the arrangement of an anti-dispersion device, and cooperates with a motor, a reciprocating screw, an L-shaped push plate, a brush plate, a rotating wheel, a brush plate assembly, a swing plate, a hollow vibration plate, a U-shaped protective shell and an arc block. The raw materials distributed on the top of the conveyor belt are pushed and brushed in the center by the brush plate, thereby improving the centrality of raw material transportation, making the gravity of the raw materials on the weighing assembly clearer, improving the weighing speed and weighing accuracy of the raw materials by the weighing assembly, and avoiding affecting the overall proportion of the fertilizer; at the same time, the swing plate is used to push the raw materials transported from the external equipment relatively in the center to reduce the amount of flying powder. At the same time, the arc-shaped protective shell is rotated and brushed by the brush plate assembly to ensure its own cleanliness, further reducing the loss of raw materials during transportation, and the brush plate carries the vibration force to brush the fine powder adhered to the surface of the conveyor belt, so that the raw materials can fall quickly after weighing.

[0015] (2) The present invention provides an anti-loosening device, and cooperates with an L-shaped push plate, a flat plate, a trapezoidal frame, a U-shaped frame, a contact plate, a heating component, a heat conduction plate, a wave plate and a contact block. During the indirect contact process of the contact plate, the conveyor belt and the driving roller are urged to always maintain good tightness, thereby preventing the conveyor belt from becoming loose after being used for too long, and constantly changing the gravity pressing data of the weighing component, thereby increasing the difficulty of fertilizer proportioning; and prompting the wave plate to further expand the heat dispersion range of the heat conduction plate, thereby drying the outer wall of the conveyor belt after unloading, thereby preventing the fertilizer transported by the conveyor belt from carrying moisture, thereby increasing the amount of adhesion between the next batch of raw materials and itself, and avoiding increased cleaning difficulty.

[0016] (3) The present invention expands the absorption range of the negative pressure fan assembly for the raw materials on the outer wall of the conveyor belt after the heat conduction plate is dried by the heat conduction plate through the arrangement of an anti-residue device, through the coordination of the heat conduction plate, the negative pressure fan assembly, the I-shaped column, the transmission belt, the cylinder, the cam, the sliding column, the U-shaped column and the guide plate, so as to avoid the raw material powder remaining on the outer wall of the conveyor belt and causing the mixing of different batches of different types of proportioned raw materials, thereby avoiding the quality degradation of the finished fertilizer or the occurrence of uncontrollable phenomena; at the same time, the guide plate continuously changes the inclination angle between itself and the negative pressure fan assembly during the reciprocating swing process, dynamically guides and shields the raw material powder at different angles sucked by the negative pressure fan assembly, reduces the possibility of powder overflow, and improves the concentrated collection effect of the negative pressure fan assembly on the residual powder.

A plurality of hollow vibration plates 47 are equidistantly and fixedly installed on the top of the L-shaped push plate 42, a U-shaped protective shell 48 is fixedly installed at the top edge of the U-shaped support plate 3, and an arc block 49 is fixedly installed on the top of the inner wall of the U-shaped protective shell 48. Through the above cooperation, the raw materials distributed on the top of the conveyor belt 22 are pushed and brushed in the center by relying on the brush plate 43, so as to improve the centrality of raw material transportation and promote The gravity of the raw materials on the weighing component 31 is made clearer, and the weighing speed and weighing accuracy of the weighing component 31 on the raw materials are improved to avoid affecting the overall ratio of the fertilizer; the brush plate 43 is caused to vibrate through the transmission of force, and the raw materials transported from the external equipment are pushed relatively to the center by the swing plate 46 through the above cooperation, so as to reduce the amount of flying powder. At the same time, the U-shaped protective shell 48 is rotated and brushed by the brush plate assembly 45 to ensure its own cleanliness, further reducing the loss of raw materials in the transportation process, and the brush plate 43 carries the vibration force to brush the fine powder adhered to the surface of the conveyor belt 22, so that the raw materials can fall quickly after weighing.

[0021] The bottom of the brush plate 43 contacts the top of the conveyor belt 22, and a U-shaped groove is provided on the top of the brush plate 43. The outer wall of the swing plate 46 is located on the right side movement trajectory of the brush plate 43. The top of the inner wall of the U-shaped protective shell 48 contacts the outer wall of the rotating wheel 44. The arc surface of the outer wall of the arc block 49 is located on the movement trajectory of the hollow vibration plate 47.

[0022] When in use, the transmission roller 21 rotates through its own built-in driving component and drives the conveyor belt 22 to perform fertilizer transmission work. The conveyor belt 22 transmits and transports the fertilizer ratio raw materials transported by external equipment. When the raw materials are laid flat on the top of the conveyor belt 22, downward gravity is generated. When the load-bearing begins, the other equipment stops operating. At this time, the gross weight of the conveyor belt 22 is removed by the weighing component 31 to weigh the raw materials and record the data. Before the raw material transportation starts, the motor on the outer wall of the U-shaped support plate 3 is started. When the output end of the motor rotates, it drives the reciprocating screw rod 41 to rotate. When the reciprocating screw rod 41 rotates, the reciprocating spiral groove on its outer wall restricts the inner wall of the L-shaped push plate 42, so that the reciprocating screw rod 41 can drive the L-shaped push plate The plate 42 slides along the inner wall of the square groove of the U-shaped support plate 3 toward the center of the base 1, and the L-shaped push plate 42 drives the brush plate 43 to slide synchronously along the top of the conveyor belt 22. Through the above cooperation, the raw materials distributed on the top of the conveyor belt 22 are pushed and brushed in the center by the brush plate 43, thereby improving the centrality of raw material transportation, making the gravity of the raw materials on the weighing component 31 clearer, and improving the weighing speed and weighing accuracy of the raw materials by the weighing component 31, so as to avoid affecting the overall ratio of the fertilizer; when the brush plate 43 moves toward the center of the base 1, it drives the rotating wheel 44 to move synchronously, and the outer wall of the rotating wheel 44 contacts the top of the inner wall of the U-shaped protective shell 48 to generate friction and start to rotate, and the rotating wheel 44 brings The dynamic brush plate assembly 45 rotates and brushes along the top of the inner wall of the U-shaped protective shell 48 toward the center of the base 1. The raw material powder attached to the top of the inner wall of the U-shaped protective shell 48 is brushed away by the brush plate assembly 45 and falls to the top of the conveyor belt 22. At the same time, the L-shaped push plate 42 loses its resistance to the swing plate 46 when moving toward the center of the base 1. The swing plate 46 causes the hinge axis between itself and the U-shaped support plate 3 to start rotating through the elastic force of the torsion spring, causing the swing plate 46 to swing toward the center of the conveyor belt 22.

[0023] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an anti-softening device 5; The anti-loosening device 5 includes a flat plate 51, a trapezoidal frame 52, a U-shaped frame 53 and a contact plate 54. The front and back sides of the flat plate 51 are fixedly installed on the inner wall of the U-shaped support plate 3. The bottom of the trapezoidal frame 52 is slidably installed on the top of the flat plate 51. The bottom of the U-shaped frame 53 is fixedly installed on the top of the flat plate 51, and the U-shaped frame 53 is located on the inner side of the trapezoidal frame 52. The outer wall of the contact plate 54 is vertically slidably installed in the slide groove of the U-shaped frame 53 through a spring. Through the above cooperation, the indirect contact process of the contact plate 54 promotes the conveyor belt 22 and the transmission roller 21 to always maintain good tightness, prevent the conveyor belt 22 from becoming loose after being used for too long, and continuously change the gravity pressing data of the weighing component 31, thereby increasing the difficulty of fertilizer matching.

[0024] The outer wall of the trapezoidal frame 52 is located on the movement track of the inner wall of the L-shaped push plate 42 , a slide groove is provided on the top of the U-shaped frame 53 , the bottom arc surface of the resistance plate 54 is located on the movement track of the trapezoidal frame 52 , and the top of the resistance plate 54 contacts the bottom of the conveyor belt 22 .

[0025] The anti-softening device 5 also includes a heating component 55, a heat conducting plate 56, a wave plate 57 and a resistance block 58. The outer wall of the heating component 55 is fixedly installed inside the trapezoidal frame 52. The bottom of the heat conducting plate 56 is slidably installed on the top of the flat plate 51 by a spring. The outer wall of the heat conducting plate 56 is located on the movement trajectory of the trapezoidal frame 52. The wave plate 57 is slidably installed on the side away from the center of the base 1 by a spring at the edge of the side of the heat conducting plate 56 close to the center of the base 1. The bottom of the resistance block 58 is fixedly installed on the top of the flat plate 51, and the top arc surface of the resistance block 58 is located on the movement trajectory of the wave plate 57. Through the above cooperation, the wave plate 57 is prompted to further expand the heat dispersion range of the heat conducting plate 56, thereby drying the outer wall of the conveyor belt 22 after unloading, preventing the fertilizer transported by the conveyor belt 22 from carrying moisture, thereby increasing the amount of adhesion between the next batch of raw materials and itself, and avoiding increased difficulty in cleaning.

[0026] When in use, the flat plate 51 provides a limited support for the trapezoidal frame 52. When the L-shaped push plate 42 pushes the trapezoidal frame 52 to slide along the top of the flat plate 51 toward the center of the base 1, the inclined surface of the trapezoidal frame 52 will contact the bottom arc surface of the contact plate 54 inside the U-shaped frame 53. At this time, the contact plate 54 generates an upward movement force and slides upward along the inner wall of the slide groove of the U-shaped frame 53, causing the top of the contact plate 54 to contact the bottom surface of the conveyor belt 22 and deform and stretch upward. Then the contact plate 54 is reset by the spring force. Through the above cooperation, the indirect contact process of the contact plate 54 causes the conveyor belt 22 and the transmission roller 21 to always maintain a good tightness, thereby preventing the conveyor belt 22 from becoming loose after being used for too long, and constantly changing the gravity pressing data of the weighing component 31, thereby increasing the difficulty of fertilizer matching; the trapezoidal frame 52 passes over the contact plate on the side close to the center of the base 1 After that, it will conflict with the heat conducting plate 56 and move along the top of the flat plate 51 toward the center of the base 1, and the trapezoidal frame 52 drives the heating component 55 to move synchronously. The heat dissipated by the heating component 55 is absorbed by the heat conducting plate 56 and diffused by sliding, and the heat conducting plate 56 drives the wave plate 57 to move synchronously when sliding. When the wave plate 57 moves toward the center of the base 1, its own arc surface is resisted by the resistance block 58. The wave plate 57 is guided by its own arc surface to slide upward along the inner wall of the wave plate 57 and reset by the spring, and so on. Through the above cooperation, the wave plate 57 is prompted to further expand the heat dispersion range of the heat conducting plate 56, thereby drying the outer wall of the conveyor belt 22 after unloading, preventing the fertilizer transported by the conveyor belt 22 from carrying moisture, thereby increasing the amount of adhesion between the next batch of raw materials and itself, and avoiding increased difficulty in cleaning.

[0027] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an anti-residue device 6; The anti-residue device 6 includes a sliding plate 61, a negative pressure fan assembly 62 and an I-shaped column 63. The bottom of the sliding plate 61 is slidably installed on the top of the flat plate 51, and a limiting groove is provided inside the sliding plate 61. The outer wall of the sliding plate 61 is located on the movement trajectory of the inner wall of the heat conducting plate 56. The bottom of the negative pressure fan assembly 62 is fixedly installed on the top of the sliding plate 61. The I-shaped column 63 is rotatably installed on the inner wall of the limiting groove of the sliding plate 61 near one end of the negative pressure fan assembly 62. The outer wall of the I-shaped column 63 contacts the top of the flat plate 51. Through the above cooperation, the absorption range of the negative pressure fan assembly 62 for the raw materials on the outer wall of the conveyor belt 22 after the heat conducting plate 56 is expanded, so as to avoid the raw material powder remaining on the outer wall of the conveyor belt 22, causing the mixing of different batches of different types of proportioned raw materials, and to avoid the quality decline or uncontrollable phenomenon of the finished fertilizer.

[0028] The anti-residue device 6 also includes a transmission belt 64, a cylinder 65, a cam 66, a sliding column 67, a U-shaped column 68 and a guide plate 69. The bottom of the inner wall of the transmission belt 64 is sleeved and transmission-mounted on the outer wall of the I-shaped column 63. The cylinder 65 is rotatably mounted on the outer wall of the negative pressure fan assembly 62 near the center of the sliding plate 61. The cam 66 is fixedly mounted on the outer wall of the cylinder 65. The sliding column 67 is slidably mounted on the outer wall of the negative pressure fan assembly 62 near the center of the sliding plate 61 through a spring. The U-shaped column 68 is fixedly mounted on the outer wall of the sliding column 67. The bottom of the guide plate 69 is hinged to the side of the negative pressure fan assembly 62 near the center of the base 1 through a torsion spring. Through the above cooperation, the inclination angle between the guide plate 69 and the negative pressure fan assembly 62 is continuously changed during the reciprocating swing of the guide plate 69, and the raw material powder at different angles sucked by the negative pressure fan assembly 62 is dynamically guided and shielded, thereby reducing the possibility of powder overflow and improving the concentrated collection effect of the negative pressure fan assembly 62 on the residual powder.

[0029] The outer wall of the cylinder 65 is drivingly connected to the top of the inner wall of the transmission belt 64 , the outer wall of the sliding column 67 is in contact with the arc surface of the outer wall of the cam 66 , and the outer wall of the guide plate 69 is in contact with the inner wall of the sliding column 67 .

[0030] When in use, when the heat conducting plate 56 moves toward the center direction of the base 1, it pushes the sliding plate 61 to slide synchronously along the top of the flat plate 51, and the sliding plate 61 drives the negative pressure fan assembly 62 to move synchronously, and the sliding plate 61 drives the I-shaped column 63 to slide synchronously along the top of the flat plate 51 to generate a rotational force and start to rotate. The I-shaped column 63 converts the sliding friction between the sliding plate 61 and the flat plate 51 into rolling friction. Through the above cooperation, the absorption range of the raw materials on the outer wall of the conveyor belt 22 after the heat conducting plate 56 is dried by the negative pressure fan assembly 62 is expanded, so as to avoid the raw material powder remaining on the outer wall of the conveyor belt 22, causing different batches of different types of mixed raw materials, and to avoid the quality of the finished fertilizer from being reduced or uncontrollable. The I-shaped column 63 drives the cylinder 65 to rotate along the outer wall of the negative pressure fan assembly 62 through the transmission belt 64, and the cylinder 65 drives the cam 66 to rotate, and the cam 66 will resist the sliding column 67 to generate an upward force. At this time, the sliding column 6 7 slides upward along the outer wall of the negative pressure fan assembly 62. The sliding column 67 ensures that it can always be in close contact with the outer wall of the cam 66 through the setting of the spring between itself and the negative pressure fan assembly 62. During the process of the sliding column 67 driving the U-shaped column 68 to move upward, the U-shaped column 68 will contact the outer wall of the guide plate 69, causing the hinge axis between the bottom of the guide plate 69 and the negative pressure fan assembly 62 close to the center of the base 1 to start rotating. At this time, the guide plate 69 rotates in an arc shape with the hinge axis as the axis toward the negative pressure fan assembly 62. Then, the guide plate 69 resets itself through the torsion spring, and repeats this process. Through the above cooperation, the inclination angle between the guide plate 69 and the negative pressure fan assembly 62 is continuously changed during the reciprocating swing of the guide plate 69, so that the raw material powder at different angles sucked by the negative pressure fan assembly 62 is dynamically guided and shielded, thereby reducing the possibility of powder overflow and improving the concentrated collection effect of the negative pressure fan assembly 62 on the residual powder.
