Description

Technical Field

[0001] This invention relates to the field of mixing technology, and in particular to a substrate fertilizer homogenizing mixing device that adapts to material humidity. Background Technology

[0002] The substrate fertilizer homogenizing and mixing equipment is specially designed for the homogenization and mixing of multiple components such as peat, coconut coir, perlite, vermiculite, fermented organic matter, organic fertilizer, slow-release fertilizer, microbial agents, and trace elements; it solves the pain points of large material density differences, easy fiber clumping, difficulty in dispersing trace fertilizers, uneven mixing, and local nutrient enrichment.

[0003] The production of uniform cultivation substrate, seedling nutrient soil, potting substrate, and organic substrate fertilizer is divided into two main categories: intermittent batch production and continuous production line production.

[0004] For example, Chinese Patent Publication No. CN216321585U discloses a connected substrate fertilizer mixing and stirring device, including a mixing vessel. A fixed frame is fixedly connected to the middle of the upper surface of the mixing vessel, and a drive motor is fixedly connected to the fixed frame. The output end of the drive motor is connected to a rotating shaft. The rotating shaft passes vertically downward through the top wall of the mixing vessel and extends to the bottom of the mixing vessel. Multiple stirring blades are fixedly connected at equal intervals on the outer side of the rotating shaft. Raw materials are placed through a set support plate, and then a cylinder is activated to cause the piston end to drive the push plate to push the raw materials, thus controlling the amount of material discharged. Then, the raw materials on both support plates enter the guide trough. The two different raw materials enter the guide trough through different support plates, so that the guide trough contains different raw materials. When the two raw materials are descending, they are impacted and then dispersed and mixed together. The mixing efficiency is high. The support plates are heated by the heat pipes to keep the outer surface of the support plates dry, so as to prevent the powdery raw materials from clumping due to moisture and improve the uniformity of the raw material mixing. The drive motor is started to rotate the shaft, and the stirring blades on the shaft further mix the raw materials, making the mixing more thorough.

[0005] In existing technical references, mixing can be carried out in a mixing vessel using stirring blades. However, this design is not suitable for the humidity of the materials, causing the materials to stick to the inner wall of the container. This not only increases the resistance during mixing, but also causes the sticky materials to deteriorate over time, resulting in a waste of resources. Summary of the Invention

[0006] To solve the above technical problems, the present invention is implemented through the following technical solution:

[0007] An adaptive substrate fertilizer homogenizing and mixing device with adjustable material moisture content includes:

[0008] The tank body and a humidity monitor installed on the bottom of the tank body are conical. A controller is installed on the side of the bottom of the tank body. A discharge pipe is installed at the bottom of the tank body. A heating component is installed on the surface of the tank body. A feeding mechanism is installed on the outside of the tank body.

[0009] A mixing mechanism includes a servo motor, a cylindrical outer shell, and a cylindrical tube. The servo motor is fixedly installed at the top of the tank. The cylindrical outer shell is rotatably installed at the top of the inner cavity of the tank. The top of the cylindrical tube is detachably fixedly installed to the bottom of the cylindrical outer shell. A support member is detachably fixedly installed on the outer surface of the cylindrical tube. A bent stirring plate is fixedly installed on the surface of the support member. A V-shaped notch is opened on the outer side of the bent stirring plate. A scraping assembly is installed between the cylindrical tube and the support member.

[0010] The rotating, bent agitator plate comes into contact with the material, and the inclined surface of the plate guides the material, causing it to be turned over and preventing accumulation. This helps to homogenize the material. The V-shaped notches evenly distributed on the sides of the bent agitator plate create a serrated edge, which breaks up any clumps of material. This allows for the diversion and dispersal of the material during mixing, breaking up agglomerates and preventing the accumulation of substrate fertilizer particles and the formation of mixing dead zones.

[0011] The scraping assembly removes material adhering to the inner wall of the tank layer by layer, adapting to the material's moisture content. The scraping assembly includes an electric telescopic rod, a guide rod, and a connecting cylinder. The electric telescopic rod is fixedly installed inside the cylindrical outer shell. The guide rod is slidably installed in the middle of the support component via a rectangular block. The connecting cylinder is slidably installed at the center of the cylindrical cylinder. A conical pressure block is fixedly connected to the outer surface of the connecting cylinder. A pressure-bearing block is fixedly connected to one end of the guide rod extending into the cylindrical cylinder. A reset spring is fixedly connected to the top of the pressure-bearing block and the inner wall of the cylindrical cylinder. A fixed... The device is equipped with a scraper. When the humidity monitor detects that the material has high humidity, it transmits the monitoring result to the controller in the form of an electrical signal. The controller receives and processes the electrical signal and controls the electric telescopic rod through the wireless control module. Since the material tends to stick to the tank wall, the telescopic end of the electric telescopic rod extends, applying a downward pushing force to the connecting cylinder. This causes the connecting cylinder to move the conical pressure block downward. The conical pressure block and the pressure block's conical surface come into contact and squeeze, pushing the guide rod to slowly extend the scraper towards the side closer to the inner wall of the tank. Meanwhile, the reset spring is squeezed and undergoes elastic deformation, scraping away the material adhering to the inner wall of the tank layer by layer and from all directions.

[0012] This equipment is equipped with a humidity monitor and controller linkage control system, which can monitor the humidity parameters of the substrate fertilizer material in the tank in real time, and intelligently control the start, stop and extension of the scraper component according to the changes in material humidity.

[0013] Furthermore, the heating component is used to heat the material inside the tank, keep it warm, and collect and reuse the heat.

[0014] The heating assembly includes an inverted conical insulation cover fitted inside the tank. An upper heater is fixedly installed at the top of the inner cavity of the inverted conical insulation cover, and a lower heater is fixedly installed at the bottom of the inner cavity of the inverted conical insulation cover. A first heating tooth is installed at the bottom of the upper heater, and a second heating tooth is installed at the top of the lower heater. A suction fan is fixedly installed on the outer side of the inverted conical insulation cover. A right-angle tube is fixedly installed between the top of the suction fan and the surface of the inverted conical insulation cover. The right-angle tube communicates with the inverted conical insulation cover to form an air supply channel.

[0015] By covering the surface of the tank with an inverted conical heat-insulating cover, the tank can be insulated. In conjunction with the staggered arrangement of the first and second heating teeth, a three-dimensional heating zone is formed, which can heat and dry the material inside the tank from all directions without dead angles and maintain a constant temperature. Under the stirring of the bent stirring plate, the material inside the tank is heated evenly, and the moisture content of high-moisture materials can be quickly adjusted to meet humidity control requirements. At the same time, the first and second heating teeth can be controlled individually or simultaneously to control the heating rate of the material inside the tank, which can be adapted to different materials.

[0016] Furthermore, the inner diameter of the inverted conical heat insulation cover gradually decreases from top to bottom, and the axis of the inverted conical heat insulation cover coincides with the axis of the tank body.

[0017] Furthermore, the first heating teeth are evenly distributed at the bottom of the upper heater, and the second heating teeth are evenly distributed at the top of the lower heater, with the first heating teeth and the second heating teeth arranged alternately.

[0018] Furthermore, the inner diameter of the tank gradually decreases from top to bottom. The humidity monitor is electrically connected to the controller, and the electric telescopic rod is controlled by the controller via a wireless control module. The central shaft at the top of the cylindrical shell is fixedly installed to the output end of the servo motor via a coupling. The cylindrical cylinder is installed vertically, and the axis of the cylindrical cylinder coincides with the axis of the tank.

[0019] Furthermore, the support members are installed horizontally, and the support members are evenly distributed on the outer surface of the cylindrical tube, while the V-shaped notches are evenly distributed on the outer side of the bent stirring plate.

[0020] Furthermore, the top end of the connecting cylinder is fixedly installed with the telescopic end of the electric telescopic rod, and the conical surface on the outer side of the conical pressure block is in contact with the conical surface of the pressure block.

[0021] Furthermore, the guide rod passes through the center of the support member, the scraper is installed at an angle, and the scraper is evenly distributed inside the tank.

[0022] When the material moisture content is normal, the controller controls the electric telescopic rod again via the wireless control module. The contraction of the telescopic rod's extension end applies an upward pulling force to the connecting cylinder, which in turn moves the conical pressure block upward. The pressure exerted by the conical pressure block on the pressed block disappears, and under the elastic force of the reset spring, the guide rod drives the scraper to automatically reset, avoiding ineffective operation. Compared to the traditional fixed scraping structure, this design can adaptively adjust the scraping stroke and operating status according to the material moisture content, solving the problems of high-moisture materials sticking to the wall and accumulating clumps. It ensures the continuity of material mixing operations under different moisture conditions and is suitable for the mixed production of substrate fertilizer raw materials with different dry and wet conditions.

[0023] Furthermore, the feeding mechanism includes a feeding channel and a bent pipe. The feeding channel is connected to the feeding port at the top of the tank, and the air inlet of the bent pipe is connected to the air outlet at the bottom of the suction fan. A feeder is fixedly installed at the top of the feeding channel, and a material lifting pipe is connected to the bottom of the feeder. A rotating shaft is rotatably installed inside the material lifting pipe. A rotating connector is installed between the air outlet of the bent pipe and the bottom end of the rotating shaft. A driver is fixedly installed at the bottom end of the material lifting pipe, and a feeding hopper is fixedly installed at the bottom of the surface of the material lifting pipe. An air passage is opened at the center of the rotating shaft, and an auger blade is fixedly connected to the surface of the rotating shaft. An air jet hole is opened inside the auger blade. By rotating the output end of the driver and under the transmission of the gear assembly, the rotating shaft is driven to rotate, and the auger blade rotates with the rotating shaft, thus lifting the material input from the feeding hopper into the material lifting pipe. The material rises to the position of the feeder, and through the feeder's feeding, the material enters the tank along the feeding channel, forming automatic feeding.

[0024] Furthermore, the outer circular surface of the rotating shaft is connected to the output end of the driver via a gear assembly. The jet holes are evenly distributed inside the auger blades. The jet holes, air passages, and bends are connected to form a hot air delivery channel. Hot air is ejected from the jet holes, which disperses the material in the gap between the auger blades and the inner wall of the material lifting pipe, and recovers heat to preheat the material in the material lifting pipe.

[0025] Using the suction power of a fan, hot air is drawn out and recovered from the inverted cone-shaped insulation hood. A complete heat recovery channel is formed by right-angle pipes and bent pipes, which transport the hot air into the air duct and spray it out from the jet hole. This disperses the material in the gap between the auger blades and the inner wall of the material lifting pipe, and recovers heat to preheat the material in the material lifting pipe, avoiding excessive temperature difference and realizing the secondary use of heat. Compared with traditional open heating equipment, this reduces the waste of heat resources.

[0026] This equipment adopts a coaxial symmetrical structure design, with the tank, mixing mechanism, and heating mechanism aligning their axes, resulting in low vibration and high stability during operation. Each core component uses a detachable assembly structure, making it easy to disassemble and assemble vulnerable parts such as support components, stirring plates, and scraper plates, facilitating future maintenance and replacement. Simultaneously, a wireless control module enables integrated intelligent control of humidity monitoring, scraping operations, heating temperature control, and heat recovery, eliminating the need for manual intervention. This high degree of automation makes it suitable for large-scale, continuous substrate fertilizer production, reducing labor costs.

[0027] The beneficial effects of the technical solution provided by this invention include:

[0028] 1. The humidity monitor detects that the material has high humidity. The humidity monitor transmits the monitoring result to the controller in the form of an electrical signal. The controller receives and processes the electrical signal and controls the electric telescopic rod through the wireless control module. Since the material easily sticks to the tank wall, the telescopic end of the electric telescopic rod extends, applying a downward pushing force to the connecting cylinder. This causes the connecting cylinder to move the conical pressure block downward. Through the conical pressure block and the conical surface of the pressure block adhering and squeezing, the guide rod pushes the scraper to slowly extend towards the side closer to the inner wall of the tank. At the same time, the reset spring is squeezed and undergoes elastic deformation, scraping away the material adhering to the inner wall of the tank layer by layer and in all directions.

[0029] Second, the rotating bending agitator plate comes into contact with the material, and the inclined surface of the bending agitator plate guides the material, causing it to be turned over, preventing material accumulation and facilitating homogeneous mixing. The V-shaped notches evenly distributed on the sides of the bending agitator plate create a serrated edge, which breaks up clumps of material. This allows for the diversion and dispersal of material during mixing, breaking up material agglomerates and preventing the accumulation of substrate fertilizer particles and the formation of mixing dead zones.

[0030] 3. When the material moisture content is normal, the contraction of the telescopic end of the electric telescopic rod eliminates the pressing pressure of the conical pressure block on the pressed block. Under the elastic force of the reset spring, the guide rod drives the scraper to automatically reset, avoiding ineffective operation. Compared with the traditional fixed scraper structure, it can adaptively adjust the scraper stroke and operating status according to the material moisture content, solve the problem of high-moisture materials sticking to the wall and accumulating lumps, ensure the continuity of material mixing operation under different moisture conditions, and adapt to the mixed production of substrate fertilizer raw materials with different dry and wet conditions.

[0031] Fourth, by covering the surface of the tank with an inverted conical heat-insulating cover, the tank can be insulated. In conjunction with the staggered arrangement of the first and second heating teeth, a three-dimensional heating zone is formed, which can heat and dry the material in the tank from all directions without dead angles and maintain a constant temperature. Under the stirring of the bent stirring plate, the material in the tank is heated evenly, and the moisture content of high-moisture materials can be quickly adjusted to meet the humidity control requirements. At the same time, the first and second heating teeth can be controlled individually or simultaneously to control the heating rate of the material in the tank, which can be adapted to different materials.

[0032] 5. By utilizing the rotation of the driver output end and the transmission of the gear assembly, the shaft is driven to rotate, and the auger blades will rotate together with the shaft, which can lift the material input from the hopper into the material lifting pipe. The material rises into the position of the feeder, and through the feeder, the material enters the tank along the feeding channel, forming automatic feeding.

[0033] 6. Utilizing the suction force of the suction fan, hot air inside the inverted cone-shaped insulation hood is drawn out and recovered. A complete heat recovery channel is formed by right-angle pipes and bent pipes, which transport the hot air into the air duct and spray it out from the jet hole. This disperses the material in the gap between the auger blades and the inner wall of the material lifting pipe, and recovers heat to preheat the material in the material lifting pipe, avoiding excessive temperature difference of the material and realizing the secondary utilization of heat. Compared with traditional open heating equipment, this reduces the waste of heat resources. Attached Figure Description

[0045] Example 1, see Figures 1-6 A technical solution is provided:

[0046] An adaptive substrate fertilizer homogenizing and mixing device with adjustable material moisture content includes:

[0047] Tank 1, and a humidity monitor 2 installed on the bottom of the surface of tank 1. Tank 1 is conical. A controller 3 is installed on the side of the bottom of tank 1. A discharge pipe 4 is installed at the bottom of tank 1. A heating component 5 is installed on the surface of tank 1. A feeding mechanism 6 is installed on the outside of tank 1.

[0048] The inner diameter of tank 1 gradually decreases from top to bottom;

[0049] The mixing mechanism 7 includes a servo motor 71, a cylindrical shell 72, and a cylindrical cylinder 73. The servo motor 71 is fixedly installed at the top of the tank body 1. The cylindrical shell 72 is rotatably installed at the top of the inner cavity of the tank body 1. The top of the cylindrical cylinder 73 is detachably fixedly installed to the bottom of the cylindrical shell 72. A support member 74 is detachably fixedly installed on the outer surface of the cylindrical cylinder 73. A bent stirring plate 75 is fixedly installed on the surface of the support member 74. A V-shaped notch 76 is opened on the outer side of the bent stirring plate 75. A scraping assembly 77 is installed between the cylindrical cylinder 73 and the support member 74.

[0050] When the servo motor 71 is turned on, the rotation of the output end of the servo motor 71 drives the cylindrical outer shell 72 to rotate, and the cylindrical cylinder 73 rotates together with the cylindrical outer shell 72. This causes the support member 74 and the bent stirring plate 75 to rotate in a circle, stirring the material in the tank 1. The bent stirring plate 75 contacts the material during rotation, and the inclined surface of the bent stirring plate 75 guides the material, making the material turn over and preventing material accumulation. This helps to homogenize and mix the material. The V-shaped notches 76 evenly distributed on the side of the bent stirring plate 75 form a serrated shape on the side of the bent stirring plate 75, which divides the sticky material. During the stirring process, the material can be diverted and dispersed, breaking up the material agglomeration and avoiding the accumulation of substrate fertilizer particles and the generation of mixing dead corners.

[0051] The support member 74 is installed horizontally and is evenly distributed on the outer surface of the cylindrical tube 73. The V-shaped notches 76 are evenly distributed on the outer side of the bent stirring plate 75.

[0052] The scraping assembly 77 scrapes away material adhering to the inner wall of the tank 1 layer by layer to adapt to the material's moisture content. The scraping assembly 77 includes an electric telescopic rod 771, a guide rod 772, and a connecting cylinder 773. The electric telescopic rod 771 is fixedly installed inside the cylindrical outer shell 72. The guide rod 772 is slidably installed in the middle of the support member 74 via a rectangular block. The connecting cylinder 773 is slidably installed at the center of the cylindrical cylinder 73. A conical pressure block 774 is fixedly connected to the outer surface of the connecting cylinder 773. A pressure block 775 is fixedly connected to one end of the guide rod 772 extending into the cylindrical cylinder 73. A reset spring 776 is fixedly connected to the top of the pressure block 775 and the inner wall of the cylindrical cylinder 73. A reset spring 776 is fixedly connected to one end of the guide rod 772 extending outside the support member 74. With a scraper 777 attached, the humidity monitor 2 detects that the material has high humidity. The humidity monitor 2 transmits the monitoring result to the controller 3 in the form of an electrical signal. The controller 3 receives and processes the electrical signal and controls the electric telescopic rod 771 through the wireless control module. Since the material is prone to sticking to the tank wall, the telescopic end of the electric telescopic rod 771 extends, applying a downward pushing force to the connecting cylinder 773. This causes the connecting cylinder 773 to move the conical pressure block 774 downward. Through the conical pressure block 774 and the conical surface of the pressure block 775, the guide rod 772 is pushed to drive the scraper 777 to slowly extend to the side closer to the inner wall of the tank 1. The reset spring 776 is squeezed and undergoes elastic deformation, scraping away the material sticking to the inner wall of the tank 1 layer by layer and in all directions.

[0053] The humidity monitor 2 is electrically connected to the controller 3. The electric telescopic rod 771 is controlled by the controller 3 through a wireless control module. The central shaft at the top of the cylindrical shell 72 is fixedly installed to the output end of the servo motor 71 through a coupling. The cylindrical cylinder 73 is installed vertically, and the axis of the cylindrical cylinder 73 coincides with the axis of the tank body 1.

[0054] When the material moisture content is normal, the controller 3 controls the electric telescopic rod 771 again through the wireless control module. The contraction of the telescopic end of the electric telescopic rod 771 applies an upward pulling force to the connecting cylinder 773. The connecting cylinder 773 drives the conical pressure block 774 to move upward. The pressing force of the conical pressure block 774 on the pressure block 775 disappears, and under the elastic force of the reset spring 776, the guide rod 772 drives the scraper 777 to automatically reset, avoiding ineffective operation. Compared with the traditional fixed scraping structure, it can adaptively adjust the scraping stroke and working state according to the material moisture content, solve the problem of high moisture material sticking to the wall and caking accumulation, ensure the continuity of material mixing operation under different moisture conditions, and adapt to the mixed production of substrate fertilizer raw materials with different dry and wet conditions.

[0055] The top of the connecting cylinder 773 is fixedly installed with the telescopic end of the electric telescopic rod 771, and the conical surface of the outer side of the conical pressure block 774 is in contact with the conical surface of the pressure block 775.

[0056] The guide rod 772 passes through the center of the support member 74, and the scraper 777 is installed at an angle and is evenly distributed inside the tank 1.

[0057] Example 2, based on Example 1, see [link / reference] Figures 1 to 7 A technical solution is provided:

[0058] The heating component 5 is used to heat the material inside the tank 1, keep it warm, and collect and reuse the heat.

[0059] The heating component 5 includes an inverted conical heat insulation cover 51, which is fitted inside the tank body 1. An upper heater 52 is fixedly installed at the top of the inner cavity of the inverted conical heat insulation cover 51, and a lower heater 53 is fixedly installed at the bottom of the inner cavity of the inverted conical heat insulation cover 51. A first heating tooth 54 is installed at the bottom of the upper heater 52, and a second heating tooth 55 is installed at the top of the lower heater 53. A suction fan 56 is fixedly installed on the outer side of the inverted conical heat insulation cover 51. A right-angle pipe 57 is fixedly installed between the top of the suction fan 56 and the surface of the inverted conical heat insulation cover 51. The right-angle pipe 57 communicates with the inverted conical heat insulation cover 51 to form a gas delivery channel. The inverted conical heat-insulating cover 51 covers the surface of the tank 1, which can keep the tank 1 warm. In conjunction with the staggered arrangement of the first heating teeth 54 and the second heating teeth 55, a three-dimensional heating zone is formed, which can heat and dry the material in the tank 1 from all directions without dead angles and keep it at a constant temperature. Under the stirring of the bent stirring plate 75, the material in the tank 1 is heated evenly, and the moisture content of high-moisture materials can be quickly adjusted to meet the humidity control requirements. At the same time, the first heating teeth 54 and the second heating teeth 55 can be controlled to be turned on and heated at the same time, so as to control the heating rate of the material in the tank 1 and adapt to different materials.

[0060] The inner diameter of the inverted conical heat insulation cover 51 gradually decreases from top to bottom, and the axis of the inverted conical heat insulation cover 51 coincides with the axis of the tank body 1.

[0061] The first heating teeth 54 are evenly distributed at the bottom of the upper heater 52, and the second heating teeth 55 are evenly distributed at the top of the lower heater 53. The first heating teeth 54 and the second heating teeth 55 are arranged alternately.

[0062] Example 3, based on Examples 1 and 2, see below. Figures 1 to 10 A technical solution is provided:

[0063] The feeding mechanism 6 includes a feeding channel 61 and a bent pipe 62. The feeding channel 61 is connected to the feeding port at the top of the tank 1. The air inlet of the bent pipe 62 is connected to the air outlet at the bottom of the suction fan 56. A feeder 63 is fixedly installed at the top of the feeding channel 61. A material lifting pipe 64 is connected to the bottom of the feeder 63. A rotating shaft 65 is rotatably installed inside the material lifting pipe 64. A rotating connector 66 is installed between the air outlet of the bent pipe 62 and the bottom end of the rotating shaft 65. A driver 67 is fixedly installed at the bottom end of the material lifting pipe 64. A feeding hopper 68 is fixedly installed at the bottom of the surface of the material lifting pipe 64. An air passage 69 is opened at the center of the rotating shaft 65. An auger blade 610 is fixedly connected to the surface of the rotating shaft 65. An air jet hole 611 is opened inside the auger blade 610.

[0064] When the driver 67 is turned on, the output of the driver 67 rotates, and the shaft 65 is driven to rotate under the transmission of the gear assembly. The auger blades 610 rotate together with the shaft 65, which can lift the material that is fed into the material lifting pipe 64 from the hopper 68. The material rises to the position of the feeder 63. Through the feeder 63, the material enters the tank 1 along the feeding channel 61, forming automatic feeding.

[0065] The outer circular surface of the rotating shaft 65 is connected to the output end of the driver 67 via a gear assembly. The jet holes 611 are evenly distributed inside the auger blades 610. The jet holes 611, the air passage 69 and the bent pipe 62 are connected to form a hot air conveying channel. Hot air is ejected from the jet holes 611, which disperses the material in the gap between the auger blades 610 and the inner wall of the material lifting pipe 64, and recovers heat to preheat the material in the material lifting pipe 64.

[0066] The suction fan 56 is turned on to operate, and the suction force of the suction fan 56 is used to draw out and recover the hot air in the inverted cone-shaped heat preservation cover 51. The right-angle pipe 57 and the bent pipe 62 form a complete heat recovery channel, which transports the hot air into the air duct 69 and sprays it out from the jet hole 611. This blows away the material in the gap between the auger blades 610 and the inner wall of the material lifting pipe 64, and recovers heat to preheat the material in the material lifting pipe 64, avoiding excessive temperature difference of the material and realizing the secondary utilization of heat. Compared with traditional open heating equipment, this reduces the waste of heat resources.

[0067] When in use, first turn on the upper heater 52 and the lower heater 53 to start working, and use the first heating tooth 54 and the second heating tooth 55 to preheat the tank 1;

[0068] The operator starts the driver 67 and starts working. The rotation of the output end of the driver 67, and the transmission of the gear assembly, causes the rotating shaft 65 to rotate. The auger blades 610 will rotate with the rotating shaft 65, which can lift the material that is fed into the material lifting pipe 64 from the feeding hopper 68. The material rises into the position of the feeder 63. Through the feeder 63, the material enters the tank 1 along the feeding channel 61, forming automatic feeding.

[0069] At the same time, the suction fan 56 is turned on to work. The suction force of the suction fan 56 is used to draw out and recover the hot air in the inverted cone-shaped heat preservation cover 51. The right-angle pipe 57 and the bent pipe 62 form a complete heat recovery channel, which delivers the hot air into the air duct 69 and sprays it out from the jet hole 611. This blows away the material in the gap between the screw conveyor blades 610 and the inner wall of the material lifting pipe 64, and recovers the heat to preheat the material in the material lifting pipe 64, so as to avoid the material temperature difference being too large.

[0070] The staff then activates the servo motor 71. The rotation of the output of the servo motor 71 drives the cylindrical outer shell 72 to rotate, and the cylindrical cylinder 73 rotates along with the cylindrical outer shell 72. This causes the support member 74 and the bent stirring plate 75 to rotate in a circular motion, stirring the material inside the tank 1. The bent stirring plate 75, in contact with the material during rotation, guides the material using its inclined surface, causing the material to be turned over and preventing material accumulation. This helps to homogenize and mix the material. The V-shaped notches 76 evenly distributed on the sides of the bent stirring plate 75 create a serrated edge, which breaks up any clumps of material. This allows for the diversion and dispersal of the material during the mixing process, breaking up material agglomeration and preventing the accumulation of substrate fertilizer particles and the formation of mixing dead zones.

[0071] Furthermore, by covering the surface of the tank 1 with an inverted conical heat insulation cover 51, the tank 1 can be insulated. In conjunction with the staggered arrangement of the first heating teeth 54 and the second heating teeth 55, a three-dimensional heating zone is formed, which can heat and dry the material in the tank 1 from all directions without dead angles and keep it at a constant temperature. Under the stirring of the bent stirring plate 75, the material in the tank 1 is heated evenly, and the moisture content of high-moisture materials can be quickly adjusted to meet the humidity regulation requirements. At the same time, the first heating teeth 54 and the second heating teeth 55 can be controlled separately or simultaneously turned on to heat together, so as to control the rate of temperature rise of the material in the tank 1 and adapt to different materials.

[0072] The humidity monitor 2 detects that the material has high humidity. The humidity monitor 2 transmits the monitoring result to the controller 3 in the form of an electrical signal. The controller 3 receives and processes the electrical signal and controls the electric telescopic rod 771 through the wireless control module. The material is easy to stick to the tank wall. The telescopic end of the electric telescopic rod 771 extends and applies a downward pushing force to the connecting cylinder 773, causing the connecting cylinder 773 to drive the conical pressure block 774 to move down. Through the conical pressure block 774 and the conical surface of the pressure block 775 to press and squeeze, the guide rod 772 drives the scraper 777 to slowly extend to the side close to the inner wall of the tank 1. The reset spring 776 is squeezed and undergoes elastic deformation, scraping away the material sticking to the inner wall of the tank 1 layer by layer and in all directions.

[0073] When the material moisture content is normal, the controller 3 controls the electric telescopic rod 771 again through the wireless control module. The contraction of the telescopic end of the electric telescopic rod 771 applies an upward pulling force to the connecting cylinder 773. The connecting cylinder 773 drives the conical pressure block 774 to move upward. The pressing force of the conical pressure block 774 on the pressure block 775 disappears, and under the elastic force of the reset spring 776, the guide rod 772 drives the scraper 777 to automatically reset, avoiding ineffective operation. Compared with the traditional fixed scraping structure, it can adaptively adjust the scraping stroke and working state according to the material moisture content, solve the problem of high moisture material sticking to the wall and caking accumulation, ensure the continuity of material mixing operation under different moisture conditions, and adapt to the mixed production of substrate fertilizer raw materials with different dry and wet conditions.

[0074] Once the substrate fertilizer material in tank 1 has been mixed, the material in tank 1 can be discharged through discharge pipe 4.

[0075] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
