Description

Technical Field

[0001] The present invention belongs to the technical field of chemical fertilizer processing, and more specifically relates to a chemical fertilizer, its processing equipment and processing method. Background Art

[0002] Coated chemical fertilizers refer to a type of chemical fertilizer that coats a semi-permeable or poorly soluble film on the surface of water-soluble chemical fertilizer particles and has the characteristic of slow nutrient release. In practical applications, coated chemical fertilizers are mainly used as basal fertilizers to improve soil structure, but they have a high cost and it is difficult to control the release rate. Especially for multi-layer stacked chemical fertilizers, during the slow release process of fertilizers, the slow release processes of multiple layers of fertilizers are prone to interact with each other, resulting in a decrease in the release rate and approaching consistency. At the same time, coated chemical fertilizers are prone to being extruded and deformed due to other accidents, such as turning the soil, etc., after the chemical fertilizer particles dissolve in water and become liquid and start to slowly release, thereby causing damage to the coating.

[0003] In addition, there is currently a method of making coated chemical fertilizers and skeletons through 3D printing in the market. For example, a fertilizer carrier formula and production method capable of extrusion 3D printing with the application number 202210735636.5 uses a degradable material mixed with nutrients as the printing raw material and can directly print fertilizer modules with different spatial distributions of target nutrients. However, the preparation of this printing raw material is relatively complex and requires multiple raw materials to be printed simultaneously. Summary of the Invention

[0030] As Figures 6-7 shown:

[0031] A chemical fertilizer, the chemical fertilizer includes a base fertilizer layer 001 and a plurality of basal fertilizer layers 003 stacked on the base fertilizer layer 001, and an outer film 002 is coated on the outside of the base fertilizer layer 001 and the stacked basal fertilizer layers 003;

[0032] The base fertilizer layer 001 is a covering layer provided on the bottom side of the finished chemical fertilizer, which plays a role in weight balancing, nutrient supply, and bottom layer protection, and can be made in different ways according to the requirements of the finished fertilizer; the base fertilizer layer 001 does not contain chemical fertilizer components that need to be slowly released, and fixing holes are provided on the base fertilizer layer 001.

[0033] Example 1 of making the base fertilizer layer 001 according to requirements: Move the 3D printing device to the left side of the bottom plate 000, print a wooden shell through an extrusion type degradable wood consumable, and drive a dividing knife 120 through a numerical control slide table 110 to cut the bottom side, so that the wooden shell is separated from the bottom plate 000, and finally fill the inside of the wooden shell with soil containing microorganisms to obtain the base fertilizer layer 001.

[0034] Example 2 of making the base fertilizer layer 001 according to requirements: Directly cut and punch a degradable resin sheet to obtain the base fertilizer layer 001.

[0035] When transporting or applying the finished fertilizer, since the base fertilizer layer 001 does not contain chemical fertilizer components that need to be slowly released, the basal fertilizer layer 003 actually containing chemical fertilizer cannot be slowly released through the base fertilizer layer 001, and can only be slowly released through the upper and side surfaces of the finished chemical fertilizer. Therefore, except for the uppermost basal fertilizer layer 003, the basal fertilizer layers 003 located in the middle side can control the slow release area of different basal fertilizer layers 003 by changing the height, and further control and adjust the slow release speed of the chemical fertilizer in different basal fertilizer layers 003.

[0036] The base fertilizer layer 003 includes a wooden framework and fertilizer particles inside the wooden framework. The wooden framework is a degradable material containing wood powder and PLA and can be obtained by extrusion 3D printing. A cylindrical opening corresponding to the vertical rotating rod 360 is provided on the upper side of the wooden framework. A cavity for storing fertilizer particles is arranged inside the wooden framework, and the cavity is connected to the cylindrical opening. Thus, fertilizer particles can be filled into the cavity by pouring fertilizer particles from the cylindrical opening. At the same time, 3D printing is flexible and can quickly adjust the overall structure of the wooden framework according to requirements. By increasing the filling of wood in the cavity, the shape of the cavity can be changed, that is, by changing the internal structure of the wooden framework, the spatial storage state of the fertilizer particles can be changed, and further the slow-release speed of the base fertilizer layer 003 can be controlled and adjusted.

[0037] In addition, using the wooden framework obtained by 3D printing as the support for the finished fertilizer can reduce the probability that the finished film-covered fertilizer is deformed due to extrusion or scraping after water-soluble slow release, resulting in film damage.

[0038] As Figures 1-7 shown:

[0039] A fertilizer processing device includes a bottom plate 000 and an upper guide rail 030. A printing and dividing frame 100 is installed on the left side of the bottom plate 000. A material storage groove 010 is provided on the right side of the bottom plate 000. A through frame 020 is provided between the printing and dividing frame 100 and the material storage groove 010. A fixing device 200 is installed on the lower side of the through frame 020. The upper guide rail 030 is arranged on the upper side of the bottom plate 000, and a grasping device is slidably connected to the lower side of the upper guide rail 030. The printing and dividing frame 100 includes two numerical control sliders 110. The two numerical control sliders 110 are connected to the upper side of the bottom plate 000 by bolts. A dividing knife 120 is connected to the sliding table on the upper side of the two numerical control sliders 110 by bolts. The fixing device 200 includes three partition plates 210. The three partition plates 210 are all connected to the lower side of the bottom plate 000 by bolts. The two partition plates 210 on the right side are respectively arranged on both sides of the through frame 020. An insertion rod 220 is connected to the left partition plate 210 through a pushing mechanism. The grasping device includes an electric telescopic rod 310. The electric telescopic rod 310 is connected to the lower side of the upper guide rail 030 by bolts. The lower side of the electric telescopic rod 310 is rotatably connected to a vertical rotating rod 360 through a rotating motor. The pushing mechanism is a power device such as a linear motor or a linear cylinder that can push the insertion rod 220 to perform reciprocating linear motion.

[0040] Before adding the base fertilizer layer 003 on the base fertilizer layer 001, a 3D printing device and a feeding device can be installed on the side of the bottom plate 000. The 3D printing device is an extrusion 3D printing device. The extrusion 3D printing device capable of extruding 3D prints of different types of wires by adjusting parameters is a mature mechanical structure. The wood-based printing extrusion consumables prepared from wood powder and curing agent are also mature technical reserves and will not be elaborated here. The feeding device is equipped with a robotic arm and an electromagnetic valve, which can automatically inject fertilizer particles into a predetermined position or can be controlled to move through a connecting rod and manually inject fertilizer particles into a predetermined position. Then, the base fertilizer layer 001 can be placed inside the fixing device 200, and a resin emulsion capable of quickly drying into a film can be injected into the storage tank 010. After the resin emulsion coats the outer side of the immersed object, it can quickly volatilize and dry into the outer coating film 002. Under normal conditions, the insertion rod 220 stays at the left end of the middle partition plate 210 under the action of the pushing mechanism.

[0041] When it is necessary to add the base fertilizer layer 003 on the base fertilizer layer 001, the 3D printing device can be controlled to print on the upper side of the base fertilizer layer 001, so as to obtain a wood skeleton on the upper side of the base fertilizer layer 001. Since the wood-based printing extrusion consumables contain a certain proportion of curing agent components, it can ensure that the printed wood skeleton can be firmly bonded to the upper side of the base fertilizer layer 001 and form an integral body, thereby avoiding the separation between the layers of the finished multi-layer stacked coated fertilizer. Then, the feeding device can be used to fill the wood skeleton with fertilizer particles to obtain the base fertilizer layer 003 bonded to the base fertilizer layer 001. Then, the processing mechanism can be started to drive the grasping device to move to the upper side of the base fertilizer layer 003 by the upper guide rail 030. Then, the electric telescopic rod 310 can be started to extend the electric telescopic rod 310, and at the same time, the rotary motor can be started, so that the vertical rotary rod 360 can rotate while gradually descending, so that the vertical rotary rod 360 can slowly squeeze into the wood skeleton of the base fertilizer layer 003, as Figure 6As shown, the cylindrical opening can reduce the deformation of the wooden skeleton during the process of the vertical rotating rod 360 squeezing into the wooden skeleton, and avoid excessive deformation and damage of the wooden skeleton caused by the extrusion of the vertical rotating rod 360. Then, the electric telescopic rod 310 can be controlled to shorten, so that the vertical rotating rod 360 can drive the semi-finished fertilizer formed by the base fertilizer layer 003 and the bottom fertilizer layer 001 to rise and move inside the fixing device 200 under the action of friction. Thus, the semi-finished fertilizer can be driven to move to the upper side of the storage tank 010 through the upper guide rail 030, and the semi-finished fertilizer can be driven to descend once by the electric telescopic rod 310, so that the semi-finished fertilizer can be completely immersed in the resin emulsion. After the electric telescopic rod 310 contracts to drive the semi-finished fertilizer to rise, the resin emulsion attached to the outside of the semi-finished fertilizer can quickly volatilize and dry to form an outer coating film 002 covering the outside of the semi-finished fertilizer, thus completing the coating process on the outside of the semi-finished fertilizer. Then, the semi-finished fertilizer can be put back into the fixing device 200 through the electric telescopic rod 310 and the upper guide rail 030. At this time, the pushing mechanism can be started to push the insertion rod 220 to move to the right, so that the insertion rod 220 can be inserted into the fixing hole on the bottom fertilizer layer 001. Then, the electric telescopic rod 310 can be started in the reverse direction. At this time, since the bottom fertilizer layer 001 is completely fixed by the insertion rod 220, the vertical rotating rod 360 can be separated from the wooden skeleton. That is, after a base fertilizer layer 003 is produced, the base fertilizer layer 003, the bottom fertilizer layer 001 adhered to the lower side of the base fertilizer layer 003 and other base fertilizer layers 003 can be grabbed by the grabbing device and moved together and coated as a whole once, so as to complete the addition work of a base fertilizer layer 003 on the bottom fertilizer layer 001. Then, the above process can be repeated until all the base fertilizer layers 003 on the bottom fertilizer layer 001 are added and produced and the outer coating film 002 is covered, completing the processing of the finished multi-layer stacked coated fertilizer.

[0042] Preferably, when there are multiple layers of the finished stacked coated fertilizers, since each time a base fertilizer layer 003 is added, the finished fertilizer is coated as a whole once more, the side surface of the lower base fertilizer layer 003 can be coated with multiple layers of outer coating films 002, and the overall thickness of the outer coating films 002 contacted by the side surfaces of different base fertilizer layers 003 is different. That is, the slow release rate of the fertilizer particles inside different base fertilizer layers 003 can also be controlled by the change in the thickness of the outer coating film 002, so that the slow release speed of the fertilizer particles inside the lower base fertilizer layer 003 is lower than that of the fertilizer particles inside the upper base fertilizer layer 003. When applying the finished fertilizer, the slow release speed of the fertilizer particles can be controlled by changing the height of the middle base fertilizer layer 003, changing the internal structure of the wooden skeleton, and adjusting the fertilizer particle filling layer at the same time. When the slow release speeds of different fertilizer particles approach the same, the slow release speeds between different fertilizer particles can be changed and enlarged through various adjustment methods, so as to achieve the effect that the slow release rates of different fertilizers are different after the finished multi-layer stacked coated fertilizer is applied.

[0043] Example 1 of adjusting the slow-release rate of fertilizer particles by changing the height of the middle base fertilizer layer 003: Set the height of the middle base fertilizer layer 003 from bottom to top as 1:2:3, and adjust the wooden skeleton structures of each layer respectively to make the masses of the fertilizer particles inside each base fertilizer layer 003 equal. Then, when the fertilizer particles dissolve and release slowly, the permeable film area can become 1:2:3, and thus the slow-release rates of different fertilizer particles can be adjusted.

[0044] Example 2 of adjusting the slow-release rate of fertilizer particles by changing the internal cavity structure of the wooden skeleton: Make the heights of each base fertilizer layer 003 the same, and increase the same number of infiltration holes from small to large on the wooden skeletons of different base fertilizer layers 003 from bottom to top during the printing process. Then, before the wooden skeleton degrades, when the fertilizer particles dissolve and release slowly, the contact film speed can be changed according to the change in the size of the infiltration holes, and thus the slow-release rates of different fertilizer particles can be adjusted.

[0045] Example 3 of adjusting the slow-release rate of fertilizer particles by adjusting the fertilizer particle filling layer: Set the fertilizer particles with a slow required slow-release rate inside the bottom base fertilizer layer 003, and set the fertilizer particles with a fast required slow-release rate inside the top base fertilizer layer 003. Then, when the fertilizer particles dissolve and release slowly, different slow-release rates can be presented according to the thickness of the outer film 002, and thus the slow-release rates of different fertilizer particles can be adjusted.

[0046] Secondly, since the semi-finished fertilizer is integrally coated with a film each time, that is, both the upper and lower sides of the semi-finished fertilizer can be immersed in the resin emulsion and coated with a film. When preparing a new base fertilizer layer 003, except for the cylindrical opening position covered by the vertical rotating rod 360, the two base fertilizer layers 003 can be separated by the outer film 002, and the cylindrical opening position can be covered and isolated by the newly printed wooden skeleton. That is, different base fertilizer layers 003 can be completely isolated by the outer film 002 and the wooden skeleton, avoiding the mutual influence of the infiltration of fertilizer particles inside different base fertilizer layers 003 during the dissolution and slow-release process, resulting in the situation where the release rates approach each other.

[0047] In addition, since no fertilizer particles are placed inside the base fertilizer layer 001, when the base fertilizer layer 001 is fixed by the insertion rod 220 and the film coated outside the fixing hole may be damaged, the damaged film will not affect the slow release of the fertilizer particles inside the base fertilizer layer 003.

[0048] Preferably, threads can be provided on the vertical rotating rod 360, so as to enhance the friction between the vertical rotating rod 360 and the wooden skeleton through the threads. During the process of slowly screwing the vertical rotating rod 360 into the wooden skeleton, since the printed wooden skeleton is relatively soft in texture, the threads on the outer side of the vertical rotating rod 360 can screw out corresponding threads on the inner wall of the cylindrical opening, thereby increasing the grasping force of the vertical rotating rod 360 on the semi-finished chemical fertilizer. At the same time, when it is necessary to separate the vertical rotating rod 360 from the wooden skeleton, reverse the rotation of the rotating motor, and the vertical rotating rod 360 can be naturally screwed out of the wooden skeleton. That is, through the above method, while increasing the grasping force of the vertical rotating rod 360 on the semi-finished chemical fertilizer, the degree of damage to the wooden skeleton caused by the vertical rotating rod 360 can be avoided.

[0049] Furthermore, when the semi-finished chemical fertilizer is integrally coated with a film, part of the vertical rotating rod 360 is also immersed in the resin emulsion, that is, part of the outer coating film 002 is also covered on the vertical rotating rod 360. When the vertical rotating rod 360 is gradually screwed into the wooden skeleton and continuously presses the inner wall of the cylindrical opening, the outer coating film 002 attached to the vertical rotating rod 360 can be pushed by the wooden skeleton around the cylindrical opening and stacked on the outside, so that the outer coating film 002 attached to the vertical rotating rod 360 will not affect the connection between the vertical rotating rod 360 and the wooden skeleton.

[0050] As Figure 4 shown:

[0051] The fixing device 200 further includes two symmetrically arranged positioning push plates 230. The two positioning push plates 230 are both arranged on the front and back sides of the through-frame 020. The two positioning push plates 230 are slidably connected between the corresponding two partition plates 210 by two air cylinders driven by the same air source;

[0052] When the base fertilizer layer 001 is placed inside the fixing device 200, the two air cylinders can be started by the air source, so that the two air cylinders respectively push the corresponding positioning push plates 230 to move inward towards the two partition plates 210, so that the two positioning push plates 230 can clamp the base fertilizer layer 001 between the two partition plates 210. At the same time, since the two air cylinders are driven by the same air source, that is, the thrusts generated by the two air cylinders on the two positioning push plates 230 are the same, it can be ensured that the base fertilizer layer 001 can be in the middle position of the fixing device 200, which facilitates the subsequent fixing of the base fertilizer layer 001 by the inserting rod 220.

[0053] Furthermore:

[0054] A plurality of inserting rods 220 are provided, and the plurality of inserting rods 220 are arranged in parallel. Insertion holes 211 corresponding to the inserting rods 220 are formed in all three partition plates 210. Thus, the fixation of the inserting rods 220 to the base fertilizer layer 001 can be enhanced through the arrangement of the plurality of inserting rods 220, avoiding the situation where the vertical rotating rod 360 and the base fertilizer layer 003 cannot be normally separated. At the same time, the arrangement of the insertion holes 211 can ensure that when the inserting rods 220 are inserted into the base fertilizer layer 001 for fixation, they can be guided and moved along the positions of the corresponding insertion holes 211 on the three partition plates 210, and further ensure that the inserting rods 220 can accurately insert into the interior of the base fertilizer layer 001 and fix the base fertilizer layer 001.

[0055] Further:

[0056] The positioning push plates 230 are all controlled by linear cylinders, so that the pressing force of the positioning push plates 230 on the base fertilizer layer 001 can be directly controlled by controlling the compressed air pressure. At the same time, the two linear cylinders can be connected to the same air source, so that the pressures generated by the two positioning push plates 230 on the base fertilizer layer 001 can be ensured to be the same, avoiding excessive deformation or displacement of the base fertilizer layer 001 due to extrusion.

[0057] As Figures 3-4 shown:

[0058] The fixing device 200 further includes a lower shelf 240. The lower shelf 240 is connected to the lower sides of the two partition plates 210 on the right by bolts. A sensor connected to the pushing mechanism of the inserting rod 220 can be installed on the upper side of the lower shelf 240 by screws. The sensor can be a common piezoelectric pressure sensor or an infrared position sensor, which will not be elaborated here. Thus, after the base fertilizer layer 001 is placed on the lower shelf 240, the pressure sensor can be activated, and then the pushing mechanism can be activated, so that the pushing mechanism can push the inserting rod 220 into the fixing hole inside the base fertilizer layer 001, and further the fixation of the base fertilizer layer 001 can be completed.

[0059] As Figures 8-9 shown:

[0060] The grasping device further includes an upper connecting plate 320. The upper connecting plate 320 is connected to the lower side of the electric telescopic rod 310 by bolts. A lower connecting plate 330 is connected to the lower side of the upper connecting plate 320 by bolts. An internal gear 340 is rotatably connected to the lower connecting plate 330 through a rotating motor. An external gear 350 is meshed with the outside of the internal gear 340. The external gear 350 is rotatably connected to the lower connecting plate 330, and the external gear 350 is welded to the upper side of the vertical rotating rod 360;

[0061] When the vertical rotating rod 360 needs to grab the base fertilizer layer 003, the grabbing device can first be moved to the upper side of the base fertilizer layer 003, and then the electric telescopic rod 310 can be controlled to start, so that the electric telescopic rod 310 extends. At the same time, the rotating motor can be started to drive the internal gear 340 by the rotating motor, and then drive the external gear 350 to rotate, so that the external gear 350 drives the vertical rotating rod 360 to rotate. Then the rotating vertical rotating rod 360 can be inserted into the interior of the wooden skeleton, and then the grabbing work of the vertical rotating rod 360 on the wooden skeleton can be completed. At the same time, when there is a thread on the outer side of the vertical rotating rod 360, the rotation direction of the vertical rotating rod 360 can be changed by controlling the rotation direction of the rotating motor, so that the vertical rotating rod 360 can be screwed into or out of the wooden skeleton interior.

[0062] As Figure 9 shown:

[0063] A plurality of the vertical rotating rods 360 are provided, and a plurality of corresponding external gears 350 are also provided. The plurality of external gears 350 are all meshed with the internal gear 340, so that the plurality of vertical rotating rods 360 can be synchronously driven to rotate by the single internal gear 340, and the rotation and extraction rates of the plurality of vertical rotating rods 360 on the wooden skeleton can be ensured to be consistent by controlling the rotation speeds of the plurality of vertical rotating rods 360 to be the same.

[0064] Furthermore:

[0065] Both the internal gear 340 and the external gear 350 are bevel gears, and the large tooth surface of the internal gear 340 is arranged upward. Thus, while the internal gear 340 drives the external gear 350 to rotate, the internal gear 340 can press the external gear 350 downward, further preventing the vertical rotating rod 360 from generating an upward thrust when it is screwed into the wooden skeleton interior, and further preventing the situation where the vertical rotating rod 360 generates an upward displacement.

[0066] A chemical fertilizer processing method includes the following steps:

[0067] S1: Pre-manufacture a base fertilizer layer 001, place the base fertilizer layer 001 inside the fixing device 200, and pour resin emulsion into the storage tank 010;

[0068] S2: Print a wooden skeleton on the upper side of the base fertilizer layer 001;

[0069] S3: Fill fertilizer particles inside the wooden skeleton to obtain a base fertilizer layer 003;

[0070] S4: Slowly lower the electric telescopic rod 310, start the vertical rotating rod 360 until the vertical rotating rod 360 is inserted into the upper side of the wooden skeleton;

[0071] S5: Release the fixation of the topdressing layer 001 on the bottom plate 000, so that the electric telescopic rod 310 can drive the topdressing layer 001 and the base fertilizer layer 003 to rise together;

[0072] S6: Make the upper guide rail 030 drive the grasping device to move to the right side of the bottom plate 000, control the electric telescopic rod 310 to descend, and make the topdressing layer 001 and the base fertilizer layer 003 completely immerse inside the resin emulsion;

[0073] S7: Use the electric telescopic rod 310 to take out the topdressing layer 001 and the base fertilizer layer 003 soaked in the resin emulsion, and make the resin emulsion volatilize and dry into the outer coating film 002 covering the topdressing layer 001 and the base fertilizer layer 003, to obtain the semi-finished fertilizer;

[0074] S8: Place the semi-finished fertilizer inside the fixing device 200, start the fixing device 200 to fix the semi-finished fertilizer, and reverse-start the vertical rotating rod 360 to make the vertical rotating rod 360 rotate out from the wooden skeleton;

[0075] S9: Print the wooden skeleton on the upper side of the semi-finished fertilizer, and repeat steps S3 - 8 until the processing of the finished coated fertilizer is completed.
