Description

Technical Field

[0001] This invention relates to the field of fertilizer mixing and formulation, and more particularly to an automated mixing production line. Background Technology

[0002] Fertilizers play a vital role in agricultural production and are a key factor in increasing grain yields. Fertilization is often necessary to promote better crop growth. However, because different crops and their growing environments vary, their fertilizer requirements also differ. With the advancement of agricultural science, applying fertilizers tailored to the soil conditions of different fields and the specific fertilizer requirements of various crops has become an important measure for scientific fertilization, increasing yields, and reducing costs.

[0003] Existing general-purpose compound fertilizers and general-purpose commercial fertilizers, due to their fixed nutrient ratios, are prone to causing deficiencies or excesses of certain nutrients, and cannot meet the requirements of various soil types and crops for mixed fertilizers with multiple ratios. Fertilizer blending machines can achieve proportional mixing of single fertilizers, thereby meeting the application needs of different soil types and crops.

[0004] However, most existing fertilizer blending equipment suffers from low automation and high labor intensity for workers. In addition, the production capacity of fertilizer blending machines is fixed and cannot meet the diverse needs of batch production, which brings many inconveniences to actual production. Summary of the Invention

[0005] This invention provides an automated batching production line, which features a high degree of automation and can accommodate both dynamic and static fertilizer batching modes. The specific technical solution is as follows:

[0006] An automated batching production line includes an unpacking device connected to a proportioning device. The proportioning device has at least two storage units. The unpacking device can move on the proportioning device to add different materials to different storage units. The proportioning device is connected to the inlet of a mixing device, where different materials from different storage units can be proportionally transported to the mixing device to mix and form a composite material. The outlet of the mixing device is connected to a packaging device, where the composite material can be transported to the packaging device. The packaging device can divide the composite material by weight and bag it to complete the production of the composite material.

[0007] Furthermore, the unpacking device includes an unpacking frame, which is movably mounted on the proportioning device. A movable frame is movably mounted above the unpacking frame and connected to a lifting assembly. The lifting assembly is connected to a bag-grabbing unit, which can drive the bag-grabbing unit to move up and down relative to the movable frame. The bag-grabbing unit can grab bagged material packages. A bag-breaking unit is located below the unpacking frame, and a crushing unit is located below the bag-breaking unit. The bag-breaking unit can cut open the packaging bag of the material package grabbed by the bag-grabbing unit, so that the material inside the material package is crushed and crushed by the crushing unit and then put into the storage unit of the proportioning device.

[0008] Furthermore, a bag collection unit is provided on the unpacking frame, and a bag-pulling unit is provided on the movable frame near the bag collection unit. The bag-pulling unit can peel off the packaging bags grabbed by the bag grabbing unit and drop them into the bag collection unit to recycle the packaging bags of the materials.

[0009] Furthermore, the bag-removing unit includes a bag-removing bracket, which is fixedly mounted on the movable frame. The end of the bag-removing bracket away from the movable frame is hinged to the bag-removing mesh fork. A bag-removing cylinder is mounted on the movable frame. The output shaft of the bag-removing cylinder is connected to the bag-removing mesh fork. The bag-removing cylinder can drive the bag-removing mesh fork to swing relative to the bag-removing bracket to peel off the packaging bag from the bag-grabbing unit.

[0010] Furthermore, the crushing unit includes a crushing support, on which multiple sets of extrusion bars are movably mounted. Each set of extrusion bars includes a first extrusion bar and a second extrusion bar, and the extrusion bars in each set are arranged sequentially. The end of the first extrusion bar near the crushing support is fixedly connected to a first rocker arm, and each first rocker arm is connected to a first connecting rod. The end of the second extrusion bar near the crushing support is fixedly connected to a second rocker arm, and each second rocker arm is connected to a second connecting rod. A crank-rocker mechanism is provided on the crushing support, which is connected to the first rocker arm and the second rocker arm respectively. The crank-rocker mechanism can drive the multiple sets of extrusion bars to swing, so as to achieve extrusion and crushing of materials.

[0011] Furthermore, the first and second extrusion bars are provided with extrusion teeth, and an extrusion space can be formed between adjacent first and second extrusion bars. The material can fall into the extrusion space, and the material can be extruded and crushed by the swinging of the extrusion teeth.

[0012] Furthermore, the proportioning device includes a proportioning frame, with multiple storage units evenly distributed on the upper part of the proportioning frame and a collection conveyor belt installed on the lower part of the proportioning frame. The upper part of the storage units is the inlet, and the lower part of the storage units is the outlet. Multiple storage units can quantitatively feed different materials onto the collection conveyor belt, which collects and transports them to the mixing device for mixing to form a composite material.

[0013] Furthermore, the collection conveyor belt is connected to the raw material elevator, and the outlet of the raw material elevator is connected to the screening device. The screening device can screen the material collected by the collection conveyor belt and then transport it to the mixing device for mixing.

[0014] Furthermore, the mixing device includes a mixing frame, on which a mixing chamber is rotatably mounted. The mixing chamber includes a mixing material inlet and a mixing material outlet. A first spiral conveyor belt and a second spiral conveyor belt are mounted on the inner side of the mixing material inlet end, and a third spiral conveyor belt is mounted on the inner side of the mixing material outlet end of the mixing chamber. The first spiral conveyor belt and the third spiral conveyor belt are fixedly mounted on the inner wall of the mixing chamber, and the second spiral conveyor belt is fixedly mounted on the inner side of the first spiral conveyor belt. The first spiral conveyor belt and the third spiral conveyor belt have the same rotation direction, and the first spiral conveyor belt and the second spiral conveyor belt have opposite rotation directions.

[0015] Furthermore, the mixing chamber includes a mixing section, a screening section, and a discharge section, which are connected sequentially. The mixing section is connected to the inlet of the mixed material, and the discharge section is connected to the outlet of the mixed material. The first and second spiral conveyor belts are located at the mixing section and the screening section, and the third spiral conveyor belt is located at the discharge section. The side wall of the mixing chamber in the screening section is provided with mesh holes, which can screen the material during the mixing process. The discharge section is converging to prevent the material from falling out of the mixed material outlet during the mixing process.

[0016] The automated batching production line of this invention is ingeniously designed, highly automated, and reduces the labor intensity of workers. The fertilizer mixing device has a highly modular overall structure, low failure rate, and stable operation. In addition, the production capacity of the automated batching production line of this invention can be flexibly selected. It can use dynamic batching to meet the needs of large production capacity, or static batching to meet the needs of small production capacity with precise proportions. It is multi-functional, highly applicable, and brings convenience to actual production.

[0030] To better understand the purpose, function, and specific design of this invention, the automated batching production line of this invention will be described in further detail below with reference to the accompanying drawings.

[0031] like Figure 1-11As shown, the automated batching production line of the present invention includes an unpacking device 1, which is connected to a proportioning device 2. The proportioning device 2 is provided with at least two storage units 21. The unpacking device 1 can move on the proportioning device 2 to add different materials to different storage units 21. The proportioning device 2 is connected to the inlet of a mixing device 3. Different materials in different storage units 21 can be transported to the mixing device 3 in proportion to mix and form a composite material. The outlet of the mixing device 3 is connected to a packaging device 4. The composite material in the mixing device 3 can be transported to the packaging device 4. The packaging device 4 can package the composite material into bags according to the target weight to complete the production of the composite material.

[0032] Specifically, such as Figure 1-7 As shown, the unpacking device 1 includes an unpacking frame 11, which is movably mounted on the proportioning device 2. A movable frame 12 is movably mounted above the unpacking frame 11. The movable frame 12 is connected to a lifting assembly 13, which is connected to a bag-grabbing unit 14. The lifting assembly 13 can drive the bag-grabbing unit 14 to move up and down relative to the movable frame 12. The bag-grabbing unit 14 can grab bagged material packages. A bag-breaking unit 17 is provided below the unpacking frame 11, and a crushing unit 16 is provided below the bag-breaking unit 17. The bag-breaking unit 17 can cut open the packaging bag of the material package grabbed by the bag-grabbing unit 14, so that the material inside the material package is crushed by the crushing unit 16 and falls into the storage unit 21 of the proportioning device 2 to complete the material delivery.

[0033] like Figure 5 As shown, the lifting assembly 13 in this embodiment includes a scissor-type telescopic arm 131. One end of the scissor-type telescopic arm 131 is connected to the movable frame 12, and the other end is connected to the bag-grabbing unit 14. The extension and retraction of the scissor-type telescopic arm 131 enables the bag-grabbing unit 14 to move up and down relative to the movable frame 12. The lifting assembly 13 also includes a lifting motor 132, which is fixedly mounted on the movable frame 12. The lifting motor 132 is connected to a sling pulley 133 via gears. A sling is wound around the sling pulley 133, and the end of the sling is connected to the bag-grabbing unit 14. The lifting motor 132 drives the sling pulley 133 to rotate, thereby extending and retracting the sling. When the sling is extended, the scissor-type telescopic arm 131 extends under the gravity of the bag-grabbing unit 14, thereby lowering the bag-grabbing unit 14. When the sling is retracted, the bag-grabbing unit 14 rises under the tension of the sling, while the scissor-type telescopic arm 131 retracts, thereby raising the bag-grabbing unit 14.

[0034] Preferably, the movable frame 12 is provided with a guide roller 134, and the bag-grabbing unit 14 is provided with a connecting roller 135. The sling passes around the guide roller 134 and connects to the connecting roller 135 to achieve the connection between the sling and the bag-grabbing unit 14. It is worth noting that in this embodiment, there are two sets of sling wheels 133, slings, guide rollers 134, and connecting rollers 135 to improve the reliability of the lifting assembly 13 during operation.

[0035] Preferably, in this embodiment, a limiting bracket 136 is also provided below the mobile frame 12 and above the bag-grabbing unit 14. The limiting bracket 136 can limit the distance between the mobile frame 12 and the bag-grabbing unit 14, so as to avoid the bag-grabbing unit 14 from colliding with the mobile frame 12 during the rising process and causing damage to the device.

[0036] The mobile frame 12 is provided with a first moving component 15, which includes a first axle and a first drive motor 151. The first axle is rotatably mounted on the mobile frame 12, and first traveling wheels 152 are connected to both ends of the first axle. The first traveling wheels 152 are mounted on the unpacking frame 11. The first drive motor 151 is connected to the first axle through gears. The first drive motor 151 can drive the first axle to rotate, thereby driving the first traveling wheels 152 to rotate, thus realizing the movement of the mobile frame 12 on the unpacking frame 11.

[0037] Preferably, the first traveling wheel 152 is provided with a groove, and the unpacking frame 11 is provided with a first guide rail that matches the groove on the first traveling wheel 152, so as to ensure the stability of the moving frame 12 when moving on the unpacking frame 11. It is worth noting that the first moving component 15 in this embodiment also includes a second wheel axle, which is rotatably mounted on the moving frame 12. The two ends of the second wheel axle are connected to first auxiliary wheels 153, which are mounted on the unpacking frame 11. The structure of the first auxiliary wheels 153 is the same as that of the first traveling wheel 152. The first auxiliary wheels 153 can move on the first guide rail to further improve the stability of the moving frame 12 when moving on the unpacking frame 11.

[0038] The bag-grabbing unit 14 in this embodiment includes a bag-grabbing frame 141, on which a plurality of bag-grabbing cylinders 142 are provided. The bag-grabbing cylinders 142 are connected to the grippers. The opening and closing of the grippers are controlled by the bag-grabbing cylinders 142 to achieve grabbing. Its specific structure is existing technology and its application in the field of unpacking machines is very mature, so it will not be described in detail here.

[0039] like Figure 6As shown, the bag-breaking unit 17 includes a bag-breaking wheel shaft 171, on which blades 172 are mounted. One end of the bag-breaking wheel shaft 171 is connected to the unpacking frame 11, and the other end is connected to a bag-breaking motor 173. The bag-breaking motor 173 can drive the bag-breaking wheel shaft 171 to rotate, thereby driving the blades 172 to rotate and cut the packaging bag of the material. Preferably, the blades 172 are circular in shape, and the center of the blades 172 coincides with the axis of the bag-breaking wheel shaft 171. There are multiple blades 172, evenly distributed on the bag-breaking wheel shaft 171, so as to cut the packaging bag from multiple directions, thereby improving the reliability of bag breaking.

[0040] like Figure 4-5 As shown, the unpacking frame 11 in this embodiment is also provided with a bag collection unit 18, and the movable frame 12 is provided with a bag-pulling unit 181 at one end near the bag collection unit 18. The bag-pulling unit 181 can peel off the packaging bag grabbed by the bag grabbing unit 14 and drop it into the bag collection unit 18 to recycle the packaging bag of the material.

[0041] The bag-removing unit 181 includes a bag-removing bracket 182, which is fixedly mounted on the movable frame 12. One end of the bag-removing bracket 182 away from the movable frame 12 is hinged to the bag-removing mesh fork 183. A bag-removing cylinder is provided on the movable frame 12. The output shaft of the bag-removing cylinder is connected to the bag-removing mesh fork 183. The bag-removing cylinder can drive the bag-removing mesh fork 183 to swing relative to the bag-removing bracket 182 to realize the function of peeling off the packaging bag on the bag-grabbing unit 14.

[0042] The bag collection unit 18 also includes a bag collection channel 184. One end of the bag collection channel 184 corresponds to the bag dispensing unit 181, and the other end is provided with a packaging bag conveying mechanism 185. The packaging bag conveying mechanism 185 can convey the packaging bags in the bag collection channel 184 to a collection box or other storage device for storage. In this embodiment, the packaging bag conveying mechanism 185 is a screw conveyor. It is understood that other existing conveying mechanisms can also be used for the packaging bag conveying mechanism 185, as long as they can convey the packaging bags in the bag collection channel 184 to a collection box or other storage device for storage.

[0043] like Figure 7As shown, the crushing unit 16 in this embodiment includes a crushing support 161, which is fixedly installed below the unpacking frame 11. Multiple sets of extrusion rods are movably mounted on the crushing support 161. Each set of extrusion rods includes a first extrusion rod 162 and a second extrusion rod 163, arranged sequentially with equal spacing between adjacent first extrusion rods 162 and 163. The end of the first extrusion rod 162 near the crushing support 161 is fixedly connected to a first rocker arm 164. Each first rocker arm 164 is connected to a first connecting rod 166, allowing each first extrusion rod 162 to rotate synchronously. The end of the second extrusion rod 163 near the crushing support 161 is fixedly connected to a second rocker arm 165. Each second rocker arm 165 is connected to a second connecting rod 167, allowing each second extrusion rod 163 to rotate synchronously. A crank-rocker mechanism 168 is provided on the crushing support 161, which drives the multiple sets of extrusion rods to swing, thereby crushing and pulverizing the material.

[0044] Preferably, the first extrusion bar 162 and the second extrusion bar 163 are provided with extrusion teeth 169, and an extrusion space can be formed between adjacent first extrusion bars 162 and second extrusion bars 163. The material can fall into the extrusion space, and the material can be extruded and crushed by the swinging of the extrusion teeth 169.

[0045] The crank-rocker mechanism 168 of this embodiment includes a turntable, on which a first crank and a second crank are hinged at an eccentric position. The first crank is connected to a first rocker arm 164 at one end, and the second crank is connected to a second rocker arm 165 at one end. The turntable is connected to a compression motor, which can drive the turntable to rotate, thereby driving the first rocker arm 164 and the second rocker arm 165 to swing, thereby causing the compression teeth 169 on the first compression rod 162 and the second compression rod 163 to swing, so as to realize the function of compression and crushing the material in the compression space.

[0046] like Figure 2 As shown, a second moving mechanism 19 is provided at the bottom of the unpacking frame 11. The second moving mechanism 19 includes a second moving motor 191 and a second moving roller 192. The second moving motor 191 can drive the second moving roller 192 to move on the proportioning device 2. Preferably, each storage unit 21 on the proportioning device 2 is provided with a position sensor so that the unpacking device 1 can accurately stop above each storage unit 21 to facilitate the feeding of materials.

[0047] The proportioning device 2 includes a proportioning frame 22. The top of the proportioning frame 22 is connected to a second moving mechanism 19. The second moving mechanism 19 can drive the unpacking device 1 to move on the top of the proportioning frame 22. Multiple storage units 21 are evenly distributed on the upper part of the proportioning frame 22. A collection conveyor belt 23 is provided on the lower part of the proportioning frame 22. The upper part of the storage unit 21 is the inlet to facilitate the unpacking device 1 to add materials. The lower part of the storage unit 21 is the outlet. Multiple storage units 21 can quantitatively add different materials to the collection conveyor belt 23, which will collect and transport them to the mixing device 3 for mixing to form a compound material.

[0048] The storage unit 21 in this embodiment includes a loss-in-weight scale, which is an automatic weighing device that achieves high-precision continuous quantitative feeding through static weighing. It can reliably, accurately, and stably feed dry bulk materials such as powders, granules, and flakes, reducing material waste and improving the consistency of mixtures, making it very suitable for the application environment of this invention. Depending on the production capacity, any commercially available loss-in-weight scale can be selected.

[0049] Preferably, each storage unit 21 is provided with a tray 24 on its side, on which bagged materials can be placed to facilitate the unpacking device 1 to grab and put them into the corresponding storage unit 21.

[0050] like Figure 1 and Figure 8 As shown, in this embodiment, the collection conveyor belt 23 is connected to the inlet of the raw material elevator 5. The raw material elevator 5 can be any commercially available elevator. In this embodiment, a bucket elevator is used. The bottom of the raw material elevator 5 is the raw material inlet, and the top of the raw material elevator 5 is the raw material outlet. The raw material outlet is connected to the mixing device 3 so as to transport the material collected by the collection conveyor belt 23 to the mixing device 3 for mixing.

[0051] Preferably, the raw material outlet of the raw material elevator 5 is connected to the screening device 6. The screening device 6 can screen the material collected by the collection conveyor belt 23, screen out impurities and large pieces of material, and then transport it to the mixing device 3 for mixing to ensure the quality of the final product.

[0052] The screening device 6 includes a screening channel 61, which is inclined. The higher end of the screening channel 61 is the screening inlet, which is connected to the raw material outlet of the raw material elevator 5. A screen 62 is installed on the side wall of the screening channel 61, which is connected to a purification channel 63. The outlet of the purification channel 63 is connected to the inlet of the mixing device 3. The material screened by the screen 62 enters the mixing device 3 through the purification channel 63 for mixing to make the final product more uniform. The lower end of the screening channel 61 is the bulk material outlet. Large pieces of material screened by the screen 62, as well as label and packaging bag fragments, are discharged from the bulk material outlet and transported to the bulk material collection bag 64 for storage.

[0053] like Figure 8-11 As shown, the mixing device 3 includes a mixing frame 31, on which a mixing chamber 32 is rotatably mounted. The mixing chamber 32 includes a mixing material inlet and a mixing material outlet. The raw material elevator 5 can transport the material collected by the summing conveyor belt 23 into the mixing device 3 through the mixing material inlet. In this embodiment, the mixing material inlet is connected to the outlet of the purification channel 63 of the screening device 6. The material after screening can enter the mixing chamber 32 through the mixing material inlet for mixing. The mixing material outlet is connected to the packaging device 4. The material after being mixed evenly is discharged through the mixing material outlet and transported into the packaging device 4 for bagging and packaging.

[0054] Specifically, in this embodiment, a first spiral conveyor belt 33 and a second spiral conveyor belt 34 are provided on the inner side of the inlet end of the mixing chamber 32, and a third spiral conveyor belt 35 is provided on the inner side of the outlet end of the mixing chamber 32. The first spiral conveyor belt 33 and the third spiral conveyor belt 35 are fixedly installed on the inner wall of the mixing chamber 32, and the second spiral conveyor belt 34 is fixedly installed on the inner side of the first spiral conveyor belt 33. The first spiral conveyor belt 33 and the third spiral conveyor belt 35 have the same rotation direction, and the first spiral conveyor belt 33 and the second spiral conveyor belt 34 have opposite rotation directions.

[0055] In this embodiment, the first spiral conveyor belt 33 and the third spiral conveyor belt 35 rotate counterclockwise when viewed from the mixture inlet to the mixture outlet, while the second spiral conveyor belt 34 rotates clockwise.

[0056] When the mixing chamber 32 rotates forward, the material near the inner wall of the mixing chamber 32 moves towards the mixing material outlet under the drive of the first spiral conveyor belt 33, and is discharged from the mixing material outlet by the drive of the third spiral conveyor belt 35; the material near the center position in the mixing chamber 32 moves towards the mixing material inlet under the drive of the second spiral conveyor belt 34, and finally falls to the position near the inner wall of the mixing material inlet end, and is then driven to the mixing material outlet by the first spiral conveyor belt 33, thereby increasing the travel of the material in the mixing chamber 32 to improve the uniformity of material mixing;

[0057] When the mixing chamber 32 is reversed, the material near the center of the mixing chamber 32 moves towards the mixing material outlet under the drive of the second spiral conveyor belt 34, and eventually falls to the vicinity of the inner wall of the mixing material outlet. At this time, the third spiral conveyor belt 35 can drive the material to move towards the first spiral conveyor belt 33. After the material reaches the first spiral conveyor belt 33, it continues to move towards the mixing material inlet under the drive of the first spiral conveyor belt 33. The material at the mixing material inlet will increase in height after accumulation, so that the material moves towards the mixing material outlet under the drive of the second spiral conveyor belt 34, so as to realize the material circulating and rolling in the mixing chamber 32 until it is evenly mixed. Then the mixing chamber 32 is rotated in the forward direction to discharge the evenly mixed material.

[0058] like Figure 8-9 As shown, the mixing chamber 32 in this embodiment includes a mixing section 36, a screening section 37, and a discharge section 38. The mixing section 36, screening section 37, and discharge section 38 are sequentially connected. The mixing section 36 is connected to the mixing material inlet, and the discharge section 38 is connected to the mixing material outlet. A first spiral conveyor belt 33 and a second spiral conveyor belt 34 are positioned at the mixing section 36 and screening section 37, respectively, and a third spiral conveyor belt 35 is positioned at the discharge section 38. The screening section 37 can screen the materials during the mixing process to improve the final product quality, and the discharge section 38 prevents materials from falling out of the mixing material outlet during the mixing process.

[0059] The mixing chamber 32 of the screening section 37 has mesh openings on its side wall. Powdered materials can be discharged through the screening section 37, while granular mixed materials are discharged through the mixed material outlet to ensure the final quality of the product. The purpose of setting up the screening section 37 is to filter out powdered fertilizer during the production of compound fertilizer, retaining only granular fertilizer to ensure the quality of the final compound fertilizer. Preferably, a powder channel 39 is fixedly installed on the mixing frame 31. The powder channel 39 is funnel-shaped and is located below the screening section 37. The inlet of the powder channel 39 corresponds to that of the screening section 37 to collect the screened powder.

[0060] The discharge section 38 is converging, which increases the resistance of the material as it moves from the discharge section 38 to the mixture outlet, so as to prevent the material from falling out of the mixture outlet.

[0061] like Figure 9As shown, a mixing drive shaft 311 is rotatably mounted on the mixing frame 31. The mixing chamber 32 is sleeved on the outside of the mixing drive shaft 311. The mixing drive shaft 311 is located at the central axis of the mixing chamber 32. Multiple fixing columns 312 are mounted on the mixing drive shaft 311 and are fixedly connected to the mixing chamber 32 to achieve the connection between the mixing chamber 32 and the mixing drive shaft 311. The mixing drive shaft 311 is connected to a mixing motor, which can drive the mixing drive shaft 311 to rotate, thereby driving the mixing chamber 32 to rotate.

[0062] Preferably, the mixing chamber 32 is inclined, with the height of the mixing material inlet end being higher than the height of the mixing material outlet end, so as to facilitate the movement of materials to the mixing material outlet end.

[0063] like Figure 1 As shown, the outlet of the mixed material is connected to the inlet of the finished product elevator 7. The finished product elevator 7 can be any commercially available elevator. In this embodiment, a bucket elevator is used. The bottom of the finished product elevator 7 is the finished product inlet, and the top of the finished product elevator 7 is the finished product outlet. The finished product outlet is connected to the packaging device 4 to transport the mixed finished material to the packaging device 4 for bagging and packaging.

[0064] The packaging device 4 includes a quantitative packaging scale 41 and a sewing machine 42. The finished product elevator 7 first conveys the finished product material into the quantitative packaging scale 41, where it performs quantitative packaging. Then, it is conveyed to the sewing machine 42 for sewing, thus completing the product production and packaging. The quantitative packaging scale 41 and the sewing machine 42 can be any commercially available quantitative packaging scale 41 and sewing machine 42.

[0065] The automated batching production line of this invention has two production modes: dynamic production with large capacity and static production with precise mixing ratio. The specific usage is as follows:

[0066] When dynamic production is adopted, the unpacking device 1 adds materials to different storage units 21 of the proportioning device 2. After the materials are added, the converging conveyor belt 23 is opened. The storage unit 21 on the side away from the raw material elevator 5 is the first storage unit, and from left to right, they are the second storage unit, the third storage unit, the fourth storage unit, and so on. The first storage unit opens first to add material, and then the second, third, and fourth storage units open in sequence to add material to the converging conveyor belt 23. At this time, the material conveyed on the converging conveyor belt 23 is a layered material, with the material added by the first storage unit at the bottom layer and the material added by the last storage unit at the top layer. The layered material is conveyed to the mixing device 3 by the raw material elevator 5 for mixing. The mixing device 3 rotates continuously in the forward direction, conveying the mixed finished material to the packaging device 4 for packaging and bagging. When the material in a certain storage unit is insufficient, the unpacking device 1 moves to the corresponding storage unit 21 to add material to ensure continuous production. It is worth noting that, as Figure 3 As shown, during large-capacity dynamic production, if one unpacking device 1 cannot meet the material feeding requirements, two or more unpacking devices 1 can be set on the proportioning device 2. Multiple unpacking devices 1 can simultaneously add materials to different storage units 21 to ensure continuous production.

[0067] In static production, the unpacking device 1 adds materials to different storage units 21 of the proportioning device 2. Each storage unit opens and feeds materials onto the consolidation conveyor belt 23 according to the proportions. At this time, the consolidation conveyor belt 23 contains multiple stacked materials. Then, the consolidation conveyor belt 23 is opened, and the multiple stacked materials are conveyed to the mixing device 3 via the raw material elevator 5 for mixing. The mixing device 3 first starts to reverse, allowing the materials to be fully mixed within the mixing device 3. Then, the mixing device 3 starts to rotate forward, conveying the mixed finished material to the packaging device 4 for packaging and bagging. It is worth noting that in dynamic production, the material is layered and has already been pre-mixed. Therefore, the mixing device 3 can meet the mixing requirements by continuously rotating forward. However, in static production, multiple stacked materials are formed. Therefore, the mixing device 3 needs to first reverse to fully mix the multiple stacked materials before rotating forward to discharge the mixed finished material.

[0068] The automated batching production line of this invention is ingeniously designed, highly automated, and reduces the labor intensity of workers. The fertilizer mixing device has a highly modular overall structure, low failure rate, and stable operation. In addition, the production capacity of the automated batching production line of this invention can be flexibly selected. It can use dynamic batching to meet the needs of large production capacity, or static batching to meet the needs of small production capacity with precise proportions. It is multi-functional, highly applicable, and brings convenience to actual production.
