Description

Technical Field

[0001] This invention relates to the field of organic fertilizer technology, specifically to a bio-organic fertilizer micronutrient addition and mixing fermentation device, and the working method of the bio-organic fertilizer micronutrient addition and mixing fermentation device. Background Technology

[0002] In the production of bio-organic fertilizer, the scientific addition of trace elements is a key link in improving the overall efficiency of fertilizer. It is necessary not only to meet the crop's demand for micronutrients, but also to improve the stability and bioavailability of trace elements through synergistic effects with organic matter in organic fertilizer. In order for trace elements to form stable chelates with humus, the best time to add trace elements is when fermentation enters the late stage of decomposition, that is, when the temperature drops below 40℃, the material is loose and there is no foul odor. However, since the fertilizer in the fermentation device is already piled up at this time, the trace elements can only be added to the surface of the fertilizer and are difficult to react with the deeper fertilizer, resulting in uneven distribution of trace elements in the fertilizer, forming local high concentration areas or local deficiencies. Summary of the Invention

[0003] This invention addresses the problems in the prior art by providing a bio-organic fertilizer micronutrient additive mixing fermentation device and method, the specific technical solution of which is as follows:

[0004] On the one hand, this application provides a bio-organic fertilizer micronutrient additive mixing fermentation device, including:

[0005] A tank containing fertilizer;

[0006] The storage silo is installed on the inner wall of the top of the tank to store trace elements;

[0007] A rotating shaft is rotatably disposed between the tank and the storage silo. A main conveying channel is provided inside the rotating shaft, and a trace element inlet connected to the main conveying channel is provided in the part of the rotating shaft that extends into the storage silo.

[0008] And multiple sets of rotating parts are arranged at equal intervals along the rotation axis. Each rotating part has a branch conveying channel that connects to the main conveying channel. The rotating part has a trace element outlet for releasing trace elements in the branch conveying channel into the tank.

[0009] Multiple sets of rotating components release trace elements as they rotate with the rotating shaft, so that the fertilizer layer and the trace element layer are alternately distributed axially upwards within the tank.

[0010] As a further technical solution of the present invention, the throttling area of ​​the trace element outlet is positively correlated with the linear velocity at that point when the outlet extends radially.

[0011] As a further technical solution of the present invention, the trace element outlet is located on the back side of the blade along the rotation direction, and the front side of the blade along the rotation direction has a sharp blade.

[0012] As a further technical solution of the present invention, the storage silo includes a conical silo body and a conveying pipe connected below the conical silo body. An auger is provided inside the conveying pipe. The rotating shaft coaxially passes through the conveying pipe and is connected to the auger. The trace element inlet is located below the auger. The auger rotates synchronously with the rotating shaft and conveys material to the main conveying channel through the trace element inlet.

[0013] As a further technical solution of the present invention, the rotating component also includes a sub-shaft and a blade. One end of the sub-shaft extends into the main conveying channel, and the other end is connected to the blade. The branch conveying channel is opened in the blade and extends through the sub-shaft to connect with the main conveying channel. The trace element outlet and the sharp blade are both provided on the blade.

[0014] The rotating component is rotatably connected to the rotating shaft via the sub-shaft;

[0015] It also includes a drive assembly, which includes a drive cylinder, a drive rod, and a linkage assembly. The drive cylinder is installed at the bottom of the tank and its output end extends into the tank. The drive rod is coaxially arranged in the main material conveying channel and rotatably connected to the drive cylinder. The linkage assembly is arranged corresponding to the rotating part. When the drive rod is driven by the drive cylinder to move axially, the rotating part is driven by the linkage assembly to rotate around the sub-axis to switch between horizontal and vertical states.

[0016] As a further technical solution of the present invention, the linkage component includes a gear, a rack and a connector. The gear is coaxially connected to the outside of the sub-shaft. The rack meshes with the gear and is connected to the drive rod through the connector. The drive rod is slidably connected to the rotating shaft to rotate synchronously with the rotating shaft.

[0017] As a further technical solution of the present invention, a clutch assembly is also included. The clutch assembly includes a ring sleeve, an outer stepped tooth groove, an inner stepped tooth groove, a clutch ring tooth, a connecting rod, and a slide rail. The ring sleeve is rotatably connected to the outside of the rotating shaft and installed at the inner ring of the auger. The outer stepped tooth groove is formed on the inner side of the ring sleeve, and the inner stepped tooth groove is formed on the outer side of the rotating shaft and corresponds to the outer stepped tooth groove. The clutch ring tooth is slidably disposed between the ring sleeve and the rotating shaft. The clutch ring tooth is connected to the drive rod through the connecting rod. The slide rail is formed inside the rotating shaft to allow the connecting rod to move axially. When the drive rod is driven by the drive cylinder to move axially, the clutch ring tooth moves synchronously and causes the auger and the rotating shaft to switch between relative rotation and synchronous rotation.

[0018] When the rotating shaft rotates, it drives the drive rod to move axially and changes the fermentation device between the feeding state and the stirring state.

[0019] In the feeding state, the auger rotates synchronously and conveys material to the tank, and the rotating part is in a horizontal state to facilitate material conveying;

[0020] During the stirring state, the auger rotates relative to the rotating shaft and stops conveying material, and the rotating component is in a vertical position to facilitate stirring.

[0021] As a further technical solution of the present invention, the portion of the rotating shaft extending into the conveying pipe has a diameter reduction section, the ring sleeve is rotatably disposed outside the diameter reduction section, and the outer diameter of the ring sleeve matches the outer diameter of the rotating shaft.

[0022] As a further technical solution of the present invention, the top of the tank is provided with a fertilizer inlet for adding fertilizer, the bottom of the tank is provided with a fertilizer outlet for discharging fertilizer, and the top of the tank is provided with a trace element replenishment port that connects to the storage bin for adding trace elements into the storage bin.

[0023] A temperature sensor is installed inside the tank, and an output motor connected to a rotating shaft is installed on the top of the tank.

[0024] On the other hand, this application also provides a method for operating a bio-organic fertilizer trace element addition and mixing fermentation device, including the following steps:

[0025] Step 1: Put the organic fertilizer raw materials into the tank for fermentation. The fermentation temperature is monitored by the temperature sensor inside the tank. When the temperature drops below 40℃, start the output motor connected to the rotating shaft drive to drive the rotating shaft to rotate.

[0026] Step 2: Trace elements are added to the storage silo through the trace element feeding port at the top of the tank. The trace elements in the storage silo are transported to the main conveying channel of the rotating shaft through the conveying pipe by the synchronous rotation of the rotating shaft and the auger, and distributed to the branch conveying channels of multiple sets of rotating parts arranged at equal intervals along the axis of the rotating shaft.

[0027] Step 3: When the rotating part rotates circumferentially with the rotating axis, the sharp edge on the front side of its blade breaks through the organic fertilizer layer stacked inside the tank, and the trace element outlet on the back side of the blade releases trace elements radially. The throttling area of ​​the trace element outlet increases with the radial linear velocity, so that the trace elements form a uniform trace element layer that is alternately distributed along the axial direction between the organic fertilizer layers, realizing a layered structure of one layer of organic fertilizer and one layer of trace elements.

[0028] Step 4: After the trace element layer is laid, the drive cylinder of the drive assembly drives the drive rod to move axially, which in turn drives the rotating part to switch from a horizontal state to a vertical state around the sub-shaft via the linkage assembly; at the same time, the drive rod drives the clutch ring teeth of the clutch assembly to move axially, disengaging from the engagement with the outer stepped tooth groove of the ring sleeve and the inner stepped tooth groove of the rotating shaft, so that the auger and the rotating shaft rotate relative to each other, stopping the trace element conveying;

[0029] Step 5: Keep the rotating shaft rotating so that the vertically rotating part can stir the layered organic fertilizer and trace elements to achieve microscopic mixing.

[0030] Step 6: After mixing is complete, stop the rotating shaft and discharge the mixed material from the fertilizer outlet at the bottom of the tank.

[0031] The beneficial effects of this invention are as follows:

[0032] (1) "Layered distribution + dynamic layer breaking mechanism";

[0033] By using multiple sets of rotating components equidistantly arranged along the rotation axis, the blades actively break through the stacked organic fertilizer layers when rotating synchronously with the axis. Within the space created by the broken layers, trace elements are released through the trace element outlet on the back side, forming an axially alternating layered structure of "one layer of organic fertilizer and one layer of trace elements". This breaks through the limitations of traditional "surface addition" and achieves for the first time a deep, layered, and uniform distribution of trace elements in stacked fertilizer, thus macroscopically solving the problem of "local enrichment or deficiency".

[0034] (2) Rotating components achieve dual uniformity in both radial and circumferential directions;

[0035] When the trace element outlet on the back side of the blade extends radially, the throttling area is positively correlated with the linear velocity at that point, meaning the outlet is larger at the far axis. The difference in linear velocity is compensated by the physical structure to ensure that the release of trace elements at each radial position is uniform.

[0036] Meanwhile, multiple sets of rotating parts are evenly distributed in the circumference, and with the stable rotation of the rotating shaft, the trace elements are covered without dead angles in the circumferential range. This breaks through the limitations of the traditional "single outlet" or "fixed flow rate" and achieves dual uniformity of trace elements in the radial and circumferential directions from a microscopic perspective.

[0037] (3) Dynamic and coordinated switching of feeding and mixing to achieve efficient integrated operation of "addition-mixing";

[0038] Through the coordinated operation of the drive component and the clutch component, "dynamic switching without stopping" is achieved:

[0039] Feeding stage: The rotating part is in a horizontal position, the sharp blade breaks through the layers and releases trace elements at the same time, and the clutch component makes the auger and the rotating shaft rotate synchronously for precise material feeding;

[0040] Mixing stage: The drive component drives the rotating part to rotate around the sub-shaft to a vertical position. At the same time, the clutch component cuts off the synchronization between the auger and the rotating shaft and stops the material conveying. The vertical blades efficiently mix the layered materials to achieve micro-mixing.

[0041] By dynamically linking the "addition" and "mixing" processes within the same equipment without stopping the machine, the optimal reaction time between trace elements and humic substances is ensured, and production efficiency is significantly improved.

[0042] (4) Coupled control of material feeding and rotation ensures the stability and controllability of the amount added;

[0043] The synchronous rotation design of the auger and the rotating shaft ensures that the amount of trace elements fed is positively correlated with the rotation speed of the rotating shaft.

[0044] When the rotating shaft speed is stable, the auger conveys material evenly; when the speed fluctuates, the material conveying amount is adjusted synchronously to ensure that the amount of trace elements added in each layer matches the thickness of the organic fertilizer layer; at the same time, the auger can block the material conveying channel when it is stationary to avoid the normal loss of trace elements; this "material conveying-rotation" coupling mechanism solves the problem of "disconnection between the amount added and the distribution rhythm" in traditional equipment and realizes precise and controllable addition process.

Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0055] Example 1

[0056] Figure 1 This diagram shows the overall structure of the bio-organic fertilizer micronutrient addition and mixing fermentation device; Figure 2 This diagram shows the internal structure of a bio-organic fertilizer micronutrient addition and mixing fermentation device. Figure 1 and Figure 2 The bio-organic fertilizer micronutrient addition and fermentation device includes a tank 100. The top of the tank 100 has a fertilizer inlet 110 for adding fertilizer, and the bottom of the tank 100 has a fertilizer outlet 120 for discharging fertilizer. In actual use, the operator can add fertilizer into the tank 100 through the fertilizer inlet 110, and discharge the fertilizer through the fertilizer outlet 120 after the fertilizer fermentation is completed. The temperature and humidity inside the tank 100 are kept constant to cooperate with the fertilizer fermentation. A temperature control device is installed inside the tank 100 to achieve constant temperature fermentation. It should be emphasized that the above-mentioned temperature control device is existing technology, and this application does not make any further improvements.

[0057] See also Figure 2The bio-organic fertilizer trace element addition and fermentation device also includes a storage silo 200, a rotating shaft 300, and a rotating component 400. The storage silo 200 is installed on the inner wall of the top of the tank 100 to hold trace elements. The top of the tank 100 has a trace element replenishment port 130 that connects to the storage silo 200 for adding trace elements into the storage silo 200. The rotating shaft 300 is rotatably mounted between the tank 100 and the storage silo 200 to guide the trace elements stored in the storage silo 200 into the tank 100. The rotating component 400 is connected to the rotating shaft 300 and lays the trace elements radially. Multiple sets of rotating components 400 are equidistantly arranged along the axial direction of the rotating shaft 300. The multiple sets of rotating components 400 rotate synchronously with the rotating shaft 300 and add trace elements. The elements form a multi-layered trace element layer within the tank 100. That is, when the rotating component 400 rotates circumferentially with the rotating shaft 300, the trace elements stored in the storage bin 200 are transported to the rotating component 400 through the rotating shaft 300 and then sprinkled out by the rotating component 400, thereby forming a trace element layer covering the fertilizer. The timing of the addition of the trace elements is based on the time after the fertilizer is piled in the tank 100 and during the final stage of fermentation. Therefore, a layered state of organic fertilizer, trace elements, organic fertilizer, trace elements, etc., can be formed in the tank 100 along the axial direction, so that the trace element layer and the organic fertilizer layer are alternately distributed in the axial direction, achieving a uniform distribution of trace elements and organic fertilizer on a macroscopic scale, which is beneficial to the mixing of organic fertilizer and trace elements.

[0058] Figure 3 A schematic diagram of the structure of the storage bin 200, the rotating shaft 300, and the auger 500 is shown. Figure 3 In the storage silo 200, there is a conical silo body 210 and a conveying pipe 220 connected below the conical silo body 210. An auger 500 is installed inside the conveying pipe 220. A rotating shaft 300 coaxially passes through the conveying pipe 220 and is connected to the auger 500. A main conveying channel 310 is opened inside the rotating shaft 300. A trace element inlet 320, connected to the main conveying channel 310, is opened on the portion of the rotating shaft 300 located in the conveying pipe 220. The trace element inlet 320 is located below the auger 500. The auger 500 rotates synchronously with the rotating shaft 300 and squeezes the material into the rotating shaft 300. The auger 500 is spaced in the material conveying path into the rotating shaft 300. When the auger 500 is stationary, it can prevent the material from flowing into the rotating shaft 300, thus avoiding the loss of trace elements under normal conditions. While the auger 500 is rotating with the rotating shaft 300, it can simultaneously convey material into the tank 100, so that the addition of material is related to the rotation of the rotating shaft 300 and the rotating component 400. Moreover, the amount of material added is also positively correlated with the rotation speed of the rotating shaft 300 and the rotating component 400, thereby ensuring that the trace element layer remains uniform in the circumferential direction even when the rotation speed of the rotating shaft 300 is unstable.

[0059] Figure 4 A schematic diagram of the rotating component 400 is shown. Figure 4 In the rotating component 400, a sub-shaft 410, a blade 420, and a feed channel 430 are included. One end of the sub-shaft 410 extends into the main feed channel 310, and the other end is connected to the blade 420. The feed channel 430 is provided inside the blade 420, and the feed channel 430 extends through the sub-shaft 410 to connect with the main feed channel 310. A trace element outlet 421 is provided on the back side of the blade 420 along the rotation direction, and a sharp blade portion 422 is provided on the front side of the blade 420 along the rotation direction. When the trace element outlet 421 extends radially, the throttling area is equal to the linear area at that point. The speed is positively correlated; when the blade 420 rotates, the side that breaks the organic fertilizer is the front side, and the other side is the back side. This makes the sharp blade 422 on the front side, which is conducive to breaking the stacked organic fertilizer and reducing the rotational resistance of the rotating part 400. Meanwhile, the trace element outlet 421 on the back side can add trace elements within the limited space broken by the sharp blade 422, reducing the difficulty of adding materials. At the same time, the throttling area of ​​the sharp blade 422 increases along the radial extension path to resist the difference in linear velocity at various positions in the radial direction when the rotating part 400 rotates, so as to achieve the uniformity of the trace element layer in the radial direction.

[0060] It should be noted that in each trace element layer, there is at least one set of rotating components 400 used for placing the trace elements, but not only one set, such as... Figure 4 In the embodiment shown, two sets are provided. In some other embodiments, when multiple sets of rotating members 400 are provided, the multiple sets of rotating members 400 are evenly distributed in the circumferential direction to ensure the stability of the rotating shaft 300 during rotation.

[0061] Figure 5 A schematic diagram of the drive component 600 is shown; Figure 5In the drive assembly 600, there are drive cylinders 610, drive rods 620, and linkage assembly 630. Drive cylinder 610 is installed at the bottom of tank 100, with its output end extending into tank 100. Drive rod 620 is coaxially disposed within the main conveying channel 310 and rotatably connected to drive cylinder 610. Linkage assembly 630 is disposed corresponding to rotating component 400. When drive rod 620 is driven by drive cylinder 610 to move axially, rotating component 400 is driven by linkage assembly 630 to rotate around sub-axis 410 to switch between horizontal and vertical states. Component 630 can drive the rotating component 400 to rotate to achieve state switching when the drive rod 620 moves upward along the axis. The correspondence between the linkage component 630 and the rotating component 400 refers to a one-to-one correspondence in position and quantity. Therefore, when the drive cylinder 610 drives the drive rod 620 to move upward along the axis, multiple sets of rotating components 400 can be driven to change states synchronously. When the rotating component 400 rotates with the rotating shaft 300 in the vertical state, it can stir the layered trace elements and organic fertilizer, so that the two are mixed at the microscopic level, improving the uniformity of the mixture of trace elements and organic fertilizer.

[0062] Figure 6 A schematic diagram of the linkage component 630 is shown; Figure 6 In the linkage assembly 630, there are gears 631, racks 632, and connectors 633. Gear 631 is coaxially connected to the outside of the sub-shaft 410. The rack 632 meshes with gear 631 and is connected to drive rod 620 through connector 633. Drive rod 620 is slidably connected to rotating shaft 300 to rotate synchronously with rotating shaft 300. When drive rod 620 moves, connector 633 drives rack 632 to move axially synchronously, thereby using rack 632 to drive gear 631 and sub-shaft 410. Rotation enables the switching of the state of the rotating component 400; the drive rod 620 and the rotating shaft 300 rotate synchronously, that is, the linkage component 630 can rotate coaxially with the rotating component 400, ensuring the stability of the current state of the rotating component 400 during rotation; and the drive rod 620 is rotatably connected to the output end of the drive cylinder 610, so the axial movement of the drive rod 620 and the rotation of its cooperating rotating shaft 300 do not interfere with each other, which is beneficial for switching the state of the rotating component 400 during rotation and achieving switching without stopping the machine.

[0063] Figure 7 A schematic diagram of the clutch assembly 700 is shown. Figure 8 An exploded view of the clutch assembly 700 is shown; Figure 7 and Figure 8In the clutch assembly 700, there are ring sleeves 710, outer stepped tooth grooves 720, inner stepped tooth grooves 730, clutch ring teeth 740, connecting rods 750, and slide rails 760. The ring sleeve 710 is rotatably connected to the outside of the rotating shaft 300 and installed at the inner ring of the auger 500. The outer stepped tooth groove 720 is formed on the inner side of the ring sleeve 710, and the inner stepped tooth groove 730 is formed on the outer side of the rotating shaft 300 and corresponds to the outer stepped tooth groove 720. The clutch ring teeth 740 are slidably disposed between the ring sleeve 710 and the rotating shaft 300. The clutch ring teeth 740 are connected to the drive rod 620 via the connecting rod 750. The slide rail 760 is formed within the rotating shaft 300 to allow the connecting rod 750 to move axially. The drive rod 620 is driven axially by the drive cylinder 610. During operation, the clutch ring tooth 740 moves synchronously, causing the auger 500 and the rotating shaft 300 to switch between relative rotation and synchronous rotation. When the clutch ring tooth 740 moves downward with the drive rod 620, it meshes with the outer stepped tooth groove 720 and the inner stepped tooth groove 730, forming synchronous rotation of the rotating shaft 300, the ring sleeve 710, and the auger 500. The auger 500 will rotate synchronously with the rotating shaft 300 to convey materials. When the clutch ring tooth 740 moves upward with the drive rod 620, it rises and disengages from the outer stepped tooth groove 720 and the inner stepped tooth groove 730. The rotating shaft 300 can no longer drive the auger 500 to rotate synchronously. At this time, only the rotating shaft 300 and the rotating component 400 rotate, and no longer convey materials into the tank 100.

[0064] Combination Figures 5-8 When the rotating shaft 300 rotates, it drives the drive rod 620 to move axially and changes the fermentation device between the feeding state and the stirring state.

[0065] In the feeding state, the auger 500 rotates synchronously and conveys material to the tank 100, and the rotating part 400 is in a horizontal state to facilitate material conveying;

[0066] During the stirring state, the auger 500 rotates relative to the rotating shaft 300 and stops conveying material, while the rotating component 400 is in a vertical position to facilitate stirring.

[0067] In other words, whether the auger 500 feeds material into the tank 100 is related to the state of the rotating component 400. When the rotating component 400 is in a horizontal state, the auger 500 can rotate synchronously with the rotating shaft 300 to achieve material feeding. When the rotating component 400 is in a vertical state, the auger 500 stops moving to allow relative rotation with the rotating shaft 300. Throughout this process, the rotating component 400 rotates continuously with the rotating shaft 300 to achieve non-stop switching.

[0068] See also Figure 8The portion of the rotating shaft 300 that extends into the conveying pipe 220 has a diameter reduction section 330. The ring 710 is rotatably disposed outside the diameter reduction section 330, and the outer diameter of the ring 710 matches the outer diameter of the rotating shaft 300. The diameter reduction section 330 allows the ring 710 to be hidden within it, avoiding the occupation of the radial space required for the rotation of the auger 500, and also preventing the formation of a stepped structure between the ring 710 and the rotating shaft 300 that would easily trap material.

[0069] A temperature sensor is installed inside the tank 100, and an output motor connected to the rotating shaft 300 is installed on the top of the tank 100. The output motor starts and drives the rotating shaft 300 to rotate when the temperature inside the tank 100 reaches a threshold. In this embodiment, the temperature threshold is below 40°C.

[0070] Example 2

[0071] A method for operating a bio-organic fertilizer micronutrient additive fermentation device includes the following steps:

[0072] Step 1: Put the organic fertilizer raw materials into the tank 100 for fermentation. The fermentation temperature is monitored by the temperature sensor inside the tank 100. When the temperature drops below 40℃, start the output motor connected to the rotating shaft 300 to drive the rotating shaft 300 to rotate.

[0073] Step 2: Trace elements are added to the storage bin 200 through the trace element feeding port 130 at the top of the tank 100. By utilizing the synchronous rotation of the rotating shaft 300 and the auger 500, the trace elements in the storage bin 200 are transported to the main conveying channel 310 of the rotating shaft 300 through the conveying pipe 220, and distributed to the branch conveying channels 430 of the multiple sets of rotating parts 400 arranged equidistantly along the axial direction of the rotating shaft 300.

[0074] Step 3: When the rotating part 400 rotates circumferentially with the rotating shaft 300, the sharp blade 422 on the front side of its blade 420 breaks through the organic fertilizer layer stacked inside the tank 100, and the trace element outlet 421 on the back side of the blade 420 releases trace elements radially. The throttling area of ​​the trace element outlet 421 increases with the radial linear velocity, so that the trace elements form a uniform trace element layer that is alternately distributed along the axial direction between the organic fertilizer layers, realizing a layered structure of one layer of organic fertilizer and one layer of trace elements.

[0075] Step 4: After the trace element layer is laid, the drive cylinder 610 of the drive assembly 600 drives the drive rod 620 to move axially, which in turn drives the rotating part 400 to switch from a horizontal state to a vertical state around the sub-shaft 410 via the linkage assembly 630; at the same time, the drive rod 620 drives the clutch ring tooth 740 of the clutch assembly 700 to move axially, disengaging from the outer stepped tooth groove 720 of the ring sleeve 710 and the inner stepped tooth groove 730 of the rotating shaft 300, so that the auger 500 and the rotating shaft 300 rotate relative to each other, stopping the trace element conveying;

[0076] Step 5: Keep the rotating shaft rotating at 30° so that the vertically rotating part at 40° can stir the layered organic fertilizer and trace elements to achieve microscopic mixing.

[0077] Step 6: After mixing is complete, stop rotating the shaft 300 and discharge the mixed material from the fertilizer outlet 120 at the bottom of the tank 100.

[0078] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.

10. The operating method of the bio-organic fertilizer trace element addition and mixing fermentation device according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Put the organic fertilizer raw materials into the tank (100) for fermentation. The fermentation temperature is monitored by the temperature sensor in the tank (100). When the temperature drops below 40℃, start the output motor connected to the rotating shaft (300) to drive the rotating shaft (300) to rotate. Step 2: Trace elements are added to the storage bin (200) through the trace element feeding port (130) at the top of the tank (100). By using the synchronous rotation of the rotating shaft (300) and the auger (500), the trace elements in the storage bin (200) are transported to the main conveying channel (310) of the rotating shaft (300) through the conveying pipe (220), and distributed to the branch conveying channels (430) of multiple sets of rotating parts (400) arranged equidistantly along the axial direction of the rotating shaft (300).

Step 4: After the trace element layer is laid, the drive cylinder (610) of the drive assembly (600) drives the drive rod (620) to move axially. The linkage assembly (630) drives the rotating part (400) to switch from a horizontal state to a vertical state around the sub-shaft (410). At the same time, the drive rod (620) drives the clutch ring tooth (740) of the clutch assembly (700) to move axially, disengaging from the engagement with the outer stepped tooth groove (720) of the ring sleeve (710) and the inner stepped tooth groove (730) of the rotating shaft (300), so that the auger (500) and the rotating shaft (300) rotate relative to each other, and the trace element conveying stops. Step 5: Keep the rotating shaft (300) rotating so that the vertical rotating part (400) stirs the layered organic fertilizer and trace elements to achieve micro-mixing of the two; Step 6: After mixing is complete, stop the rotating shaft (300) and discharge the mixed material from the fertilizer outlet (120) at the bottom of the tank (100).
