Description

Technical Field

[0001] The invention belongs to the technical field of production and processing of blended fertilizers, and in particular relates to a blended fertilizer raw material potash fertilizer and a preparation method thereof. Background Art

[0002] Blended fertilizer is a fertilizer made by mixing two or more granular raw materials with fertilizer effect through physical methods.

[0003] The inventors found that the existing blended fertilizers have limited nutrients for plant growth, resulting in poor fertilizer use effects; and in the production and processing of existing blended fertilizers, the raw materials are simply fed into a mixer for mixing. This method is prone to uneven distribution, resulting in insufficient mixing of the raw materials and a long mixing time for the raw materials, which seriously affects the overall production efficiency. In addition, since the raw materials themselves are easily affected by moisture and become hardened, the raw materials are easily blocked when being discharged, which also greatly affects the overall production efficiency.

[0020] Compared with the prior art, the present invention has the following technical effects:

[0021] Potassium sulfate is included as the main source of potassium fertilizer, which can provide potassium for crop growth, enhance crop resistance (such as drought resistance, cold resistance, lodging resistance, etc.), promote the transportation and transformation of photosynthesis products, and improve crop quality and yield. It is especially suitable for crops with high potassium demand such as tobacco, fruit trees, vegetables, etc. Zinc sulfate monohydrate provides zinc, which is a component or activator of many enzymes and participates in the physiological processes of plant auxin synthesis, photosynthesis, respiration, etc. It helps to promote the development of crop growth points, prevent zinc deficiency symptoms such as leaflet disease, and improve crop fruiting rate and fruit setting rate. Magnesium sulfate heptahydrate supplements magnesium, which is an important component of chlorophyll and can ensure normal photosynthesis of plants. It also participates in the activation of multiple enzymes in plants, promotes the synthesis of carbohydrates, fats and proteins, and is essential for maintaining the green and healthy growth of crop leaves, which is conducive to improving the overall growth vitality and yield of crops. Sodium octaborate tetrahydrate provides boron, which has a significant effect on the reproductive growth of crops. It can promote pollen germination and pollen tube elongation, increase the flowering and fruiting rate of crops, and reduce the phenomenon of falling flowers and fruits. It is particularly important for flowering and fruiting crops such as fruit trees and rapeseed, and can significantly increase their yield and fruit quality. DA-7 is a plant growth regulator analog that can promote plant cell division and elongation, improve plant photosynthetic efficiency, enhance plant stress resistance and nutrient absorption ability, make crops grow stronger, and improve fertilizer utilization. Seaweed polysaccharides have multiple biological activities, can improve soil structure, increase soil water and fertilizer retention capacity, promote soil microbial reproduction and activity, and create a good soil environment for crop growth. At the same time, seaweed polysaccharides can also stimulate crop growth, improve crop immunity, and reduce the occurrence of diseases and insect pests.

[0022] The design of the raw material box, discharge port and discharge conveyor belt can realize the transportation of materials by rotating the discharge conveyor belt, and the flow rate of different discharge ports can be designed so that different materials can be laid layer by layer on the discharge conveyor belt during the rotation and transportation process. Such a design can make the materials mixed to a certain extent during the transportation process, which can greatly reduce the mixing time of materials in the mixer and improve the overall production efficiency;

[0023] The design of the knocking plate, limit slider, knocking motor and knocking cam can realize the vibration of the discharge hopper by rotating the knocking cam, and the vibration can effectively prevent the material from being compacted or the discharge port from being blocked. The two ends of the knocking plate can move back and forth in the corresponding slide groove, which cooperates with the back and forth movement of the limit slider. The knocking cam can vibrate one side of the discharge hopper more evenly and can vibrate and knock every place on one side wall of the discharge hopper. In this way, the compacted material can be knocked more thoroughly, the material can be better crushed, thereby better discharging, and the efficiency of handling compacted materials can be improved, thereby improving the overall production efficiency.

[0040] Example 1, a mixed fertilizer raw material potash fertilizer, including the following raw materials in parts by weight: 980 parts of potassium sulfate powder, 3 parts of zinc sulfate monohydrate, 10 parts of magnesium sulfate heptahydrate, 2 parts of sodium octaborate tetrahydrate, 1 part of DA-7, and 4 parts of seaweed polysaccharides.

[0041] See also Figure 1 , Figure 2 , a method for preparing a potash fertilizer blended with a fertilizer raw material, comprising the following steps:

[0042] S1 quickly delivers 980 parts of potassium sulfate powder, 3 parts of zinc sulfate monohydrate, 10 parts of magnesium sulfate heptahydrate, 2 parts of sodium octaborate tetrahydrate, 1 part of DA-7, and 4 parts of seaweed polysaccharide raw materials from the discharge port at the bottom of the raw material box 1 to the discharge conveyor belt 2 below, and the raw materials are transported to the feed end of the first elevator 3 through the discharge conveyor belt 2;

[0043] S2 feeds the raw materials into the mixer 4 through the first elevator 3, so that the multiple raw materials are repeatedly mixed evenly, and the mixed materials are poured into the feeding end of the second elevator 5;

[0044] S3 transports the material to the feed end of the hydraulic extruder 6 through the second elevator 5, extrude and granulate the material to form fertilizer granules, which can then be packaged and shipped out.

[0045] The design of the raw material box 1, the discharge port and the discharge conveyor belt 2 can realize the transportation of materials by rotating the discharge conveyor belt 2, and the flow rates of different discharge ports can be designed so that different materials can be laid layer by layer on the discharge conveyor belt 2 during the rotating transportation process. Such a design can mix the materials to a certain extent during the transportation process, which can greatly reduce the time for mixing and stirring the materials in the mixer 4 and improve the overall production efficiency.

[0046] See also Figure 2 and Figure 3 In the present embodiment, there are multiple raw material boxes 1, and the raw material boxes 1 are interconnected. An inverted quadrangular pyramid-shaped discharge hopper 12 is provided at the bottom of the raw material box 1, and the discharge port is arranged at the bottom of the discharge hopper 12. Fixed plates 13 are fixedly connected at the upper and lower ends of the outer wall of the discharge hopper 12, and slide grooves 131 are arranged on the fixed plates 13. A retractable knocking plate 15 is also provided on the outer wall of the discharge hopper 12. Both ends of the knocking plate 15 can be moved back and forth in the corresponding slide grooves 131, and a through-type limit groove 154 is provided on the knocking plate 15. A limit slider 16 that can reciprocate back and forth is provided in the limit groove 154. A fixedly connected knocking motor 162 is provided on the limit slider 16, and a knocking cam 161 for knocking on the side wall of the discharge hopper 12 is provided at the output end of the knocking motor 162.

[0047] The design of the knocking plate 15, the limit slider 16, the knocking motor 162 and the knocking cam 161 can realize the vibration of the discharge hopper 12 by rotating the knocking cam 161. Through the vibration, the material can be effectively prevented from being compacted or the discharge port can be blocked. The two ends of the knocking plate 15 can be moved back and forth in the corresponding slide groove 131, which cooperates with the back and forth movement of the limit slider 16. The knocking cam 161 can vibrate one side of the discharge hopper 12 more evenly, and can vibrate and knock every place on the side wall of the discharge hopper 12. In this way, the compacted material can be knocked more thoroughly, the material can be better crushed, thereby better discharging, and the efficiency of processing compacted materials can also be improved.

[0048] See also Figure 3 and Figure 4 In this embodiment, guide grooves 133 are provided on the upper and lower inner walls of the slide groove 131, and guide plates 173 are slidably connected in the guide grooves 133. The guide plates 173 are provided with rotating shafts 155 that are rotatably connected. The rotating shafts 155 are connected to the corresponding knocking plates 15. A matching and fixedly connected fixed block 17 is provided in the slide groove 131. Adjustment shafts 174 that can move back and forth are provided at the upper and lower ends of the fixed block 17, and the ends of the adjustment shafts 174 are respectively connected to the corresponding guide plates 173.

[0049] The design of the guide groove 133, the guide plate 173, the rotating shaft 155 and the adjusting shaft 174 can push the guide plate 173 to reciprocate through the back-and-forth movement of the adjusting shaft 174, thereby realizing the reciprocating motion of the two ends of the knocking plate 15. The design of the rotating shaft 155 and the guide plate 173 can ensure the stable operation of the knocking plate 15 by rotating the rotating shaft 155 when the two ends of the knocking plate 15 move asynchronously.

[0050] In this example, see Figure 3 , Figure 4 and Figure 5 The knocking plate 15 includes a first sub-plate 151, a second sub-plate 152 and a third sub-plate 153. The second sub-plate 152 is fixedly connected to the third sub-plate 153. One end of the third sub-plate 153 is matched and connected with the corresponding sliding groove 131. One end of the first sub-plate 151 is provided with a first sub-slot 159. The extended end of the second sub-plate 152 is slidably connected with the first sub-slot 159. The other end of the first sub-plate 151 is matched and connected with the corresponding sliding groove 131. The limiting groove 154 is arranged in the first sub-slot 159. The design of the first sub-plate 151, the second sub-plate 152 and the third sub-plate 153 can ensure that the knocking plate 15 can rotate and the stable operation of the knocking plate 15 by sliding the second sub-plate 152 back and forth in the first sub-slot 159 when the displacements at the two ends of the knocking plate 15 are different.

[0051] In this example, see Figure 5 , Figure 6 , both side walls of the limit slot 154 are provided with limit slots 156, both ends of the limit slider 16 are slidably connected with the limit slots 156, and reciprocating rods 168 that can rotate synchronously are provided in the limit slots 156, and the reciprocating rods 168 are provided with first reciprocating threads 1681, and the limit slider 16 is provided with a reciprocating hole for the reciprocating rod 168 to pass through and matched with the first reciprocating threads 1681. Through the rotation of the reciprocating rod 168 and the characteristics of the reciprocating threads, the limit slider 16 automatically performs periodic reciprocating motion in the limit slot 154.

[0052] In this example, see Figure 5 , Figure 6 A rotatably connected driving shaft 169 is provided in each of the limit slots 156, a through-type driving hole is provided on the limit slider 16 for the driving shaft 169 to pass through, and a rotatably connected driving ring plate 164 is provided on the limit slider 16, a synchronous groove 166 is provided on the driving shaft 169, and the driving shaft 169 passes through the middle of the driving ring plate 164, a synchronous block fixedly connected and slidably connected to the synchronous groove 166 is provided on the inner wall of the driving ring plate 164, a first synchronous chain 167 connected between adjacent driving shafts 169 and reciprocating rods 168, an output shaft 163 is provided at the output end of the knocking motor 162, the output shaft 163 is connected to the knocking cam 161, and a second synchronous chain 165 connected between the output shaft 163 and the corresponding driving ring plate 164 is provided.

[0053] The design of the drive shaft 169, the drive ring plate 164, the synchronization block and the synchronization groove 166 enables the drive ring plate 164 to reciprocate along the drive shaft 169 during the rotation process. The design of the first synchronization chain 167 between the drive shaft 169 and the reciprocating rod 168 and the second synchronization chain 165 between the output shaft 163 and the drive ring plate 164 enables the drive motor to drive the knocking cam 161 to rotate while also driving the drive ring plate 164 to rotate through the second synchronization chain 165. The rotation of the drive ring plate 164 can drive the drive shaft 169 to rotate, and the rotation of the drive shaft 169 can drive the reciprocating rod 168 to rotate continuously. Combined with the characteristics of the reciprocating thread, the limit slider 16 can automatically reciprocate in the limit groove 154, so that the knocking cam 161 can reciprocate while knocking.

[0054] In this example, see Figure 4 , Figure 7 A second reciprocating thread 172 is provided on the adjusting shaft 174, an adjusting hole for the adjusting shaft 174 to pass through and matched with the second reciprocating thread 172 is provided on the fixing block 17, a driving mechanism for driving the adjusting shaft 174 to rotate is provided on the knocking plate 15, the driving mechanism includes a driving rack 178 and a driving gear 176, both ends of the knocking plate 15 are provided with a through-type connecting groove 158 for connecting the upper and lower adjacent adjusting shafts 174, a driving gear 176 connected in rotation is provided in the connecting groove 158, a central shaft 177 connected in one-way rotation is provided in the middle of the driving gear 176, a third synchronous chain 175 connected to the central shaft 177 and the corresponding adjusting shaft 174 is provided, and a transverse groove 157 that crosses the connecting groove 158 is provided in the knocking plate 15, and the driving rack 178 is arranged in the transverse groove 157 so as to move back and forth, and the driving rack 178 is meshed with the corresponding driving gear 176. Since the discharge hopper 12 is in the shape of an inverted quadrangular pyramid, the side surface of the discharge hopper 12 is trapezoidal. Therefore, during the movement of the knocking plate 15, the displacement of the upper end of the knocking plate 15 is greater than the displacement of the lower end of the knocking plate 15 each time. The difference in displacement can be controlled by setting a different pitch of the second reciprocating thread 172 to control two different displacements, thereby achieving better movement of both ends of the knocking plate 15 to one side.

[0055] The driving rack 178 can move back and forth, and drives the driving gear 176 to rotate through the meshing transmission of the gears. The rotation of the driving gear 176 can drive the rotation of the adjusting shaft 174 through the central shaft 177 and the third synchronous chain 175, so that the adjusting shaft 174 can rotate automatically. Combined with the characteristics of the reciprocating thread, the position of one end of the knocking plate 15 can be automatically changed, and the end of the knocking plate 15 can automatically move back after moving to the set position.

[0056] In this example, see Figure 7 , Figure 8 , one of the transverse grooves 157 is connected to one end of the corresponding limit slot 156, the end of the driving rack 178 is located in the limit slot 156, the other transverse groove 157 is set in the third plate, the other transverse groove 157 is provided with a fixedly connected first hydraulic telescopic rod 1593, the end of the first hydraulic telescopic rod 1593 is fixedly connected to the corresponding driving rack 178, the other side of the limit slot 156 is provided with a fixedly connected second hydraulic telescopic rod 1592, the first slot 159 is provided with a connecting hose 1591, one end of the connecting hose 1591 is connected to the first hydraulic telescopic rod 1593, and the other end of the connecting hose 1591 is connected to the second hydraulic telescopic rod 1592, and the two transverse grooves 157 are provided with a reset spring 1783 for driving the driving rack 178 to automatically restore the initial position. The limit slider 16 can move to the two ends of the limit slot 156 to realize the automatic squeezing of the driving rack 178, thereby realizing the automatic change of the position of the two ends of the knocking plate 15. Among them, a reset groove 1782 is provided on the side wall of the cross groove 157, and a slidingly connected reset block 1781 is provided in the reset groove 1782. The reset block 1781 is fixedly connected to the driving rack 178, and a reset spring 1783 is arranged in the reset groove 1782, and the reset spring 1783 is used to drive the reset block 1781 to automatically restore the initial position.

[0057] In this example, see Figure 2 , Figure 3 , one side of the multiple discharge hoppers 12 is flush, a fixed support frame 11 is provided between the multiple raw material boxes 1, both ends of the fixing plate 13 are fixedly connected to the corresponding support frame 11, and the fixing plate 13 is laid flush on the same side of the discharge hopper 12, a plurality of locking holes 132 are provided on the fixing plate 13, locking bolts 14 are provided in the locking holes 132, and bolt holes 171 matching the locking bolts 14 are provided on the fixing block 17. Since not all raw material boxes 1 will be hardened at the same time, such a design can realize that only one knocking motor 162 is needed to knock the discharge hoppers 12 of multiple raw material boxes 1, reducing the overall cost.

[0058] When this embodiment is used:

[0059] When the material slab is clogged in one of the discharge hoppers 12, the fixing between the fixing block 17 and the chute 131 is released by rotating the locking bolt 14, and then the knocking plate 15 is moved to the clogged discharge hopper 12, and the fixing block 17 is connected and fixed to the chute 131 by threading the locking bolt 14 with the bolt hole 171;

[0060] At this time, the knocking motor 162 is started to drive the knocking cam 161 to rotate, and the side wall of the discharge hopper 12 is vibrated and knocked. The rotation of the knocking cam 161 can drive the output shaft 163 to rotate, and the driving ring plate 164 is driven to rotate through the second synchronous chain 165. The rotation of the driving ring plate 164 can drive the driving shaft 169 to rotate synchronously through the synchronous block, and the synchronous rotation of the driving shaft 169 can drive the reciprocating rod 168 to rotate synchronously through the first synchronous chain 167, so that when the output shaft 163 of the knocking motor 162 rotates, the reciprocating rod 168 also rotates synchronously and continuously. Under the action of the first reciprocating thread 1681, the limit slide block 16 moves from one end of the limit slot 154 to the other end, so that the knocking cam 161 is vibrated and knocked synchronously with the movement of the limit slide block 16.

[0061] When the limit slider 16 moves to one end of the limit slot 154, the limit slider 16 squeezes the drive rack 178, drives the drive gear 176 to rotate through the meshing of the gears, and then drives the adjustment shaft 174 on the same side to rotate synchronously through the central shaft 177 and the third synchronous chain 175. The synchronous rotation of the adjustment shaft 174, under the action of the second reciprocating thread 172, makes the adjustment shaft 174 extend, so that one end of the knocking plate 15 automatically moves a set amount; and when the limit slider 16 moves toward the other end and separates from the drive rack 178, the reset spring 1783 can drive the drive rack 178 to automatically restore the initial position, and because the central shaft 177 is connected to the drive gear 176 in a one-way rotation, the adjustment shaft 174 will not be driven to rotate;

[0062] When the limit slider 16 moves to the other end of the limit slot 154, the limit slider 16 will automatically squeeze the second hydraulic telescopic rod 1592, and through the hydraulic transmission of the connecting hose 1591, the first hydraulic telescopic rod 1593 will be automatically extended, so that the driving rack 178 moves, thereby driving the adjusting shaft 174 at the other end to rotate synchronously, so that the other end of the knocking plate 15 can automatically move the set displacement; and when the limit slider 16 is separated, the reset spring 1783 can automatically drive the corresponding driving rack 178 to restore the initial position, and because the central shaft 177 is connected to the driving gear 176 in a one-way rotation connection, it will not drive the adjusting shaft 174 to rotate, waiting for the next squeezing;

[0063] In this way, the knocking cam 161 can knock and vibrate the side of the discharge hopper 12 in an all-round manner, so that the compacted materials can be broken more thoroughly and more efficiently.
