Description

Technical Field

[0001] This invention relates to the field of fertilizer enhancement technology, and in particular to a spectral fertilizer enhancement device. Background Technology

[0002] Spectroscopic fertilizer enhancement is a physical enhancement technology based on photochemical effects. It uses photon energy to act on nutrient molecules, altering their crystal structure and chemical bond energies. This transforms insoluble phosphorus, potassium, and trace elements into readily absorbable forms, improving nutrient solubility and biological activity without altering the original chemical composition and ratio of the fertilizer, leaving no chemical additive residues. Enhancement devices are required for fertilizer enhancement. However, existing fertilizer enhancement devices still have the following drawbacks: In fertilizer enhancement processes, the dispersion state of the material directly determines the uniformity of the enhancement effect and the final treatment result. Moisture-induced clumping is a typical production problem that restricts the stability of the enhanced quality. If the environmental humidity is too high or the moisture content of the raw materials is not properly controlled during storage or pre-processing, the surface of the fertilizer particles will gradually absorb moisture and dissolve. After drying, crystal bridges will form, gradually agglomerating into compact clumps of varying sizes, with an overall particle size far exceeding that of a single fertilizer particle. Current mainstream physical enhancement technologies mostly rely on energy fields acting on the surface of fertilizer particles to take effect. For example, spectral irradiation relies on photon energy to change the molecular structure of surface nutrients. Its effective depth is limited, only covering a certain thickness of the particle surface. When fertilizer forms compact clumps, the enhancement energy can only act on the outer surface of the clumps and cannot penetrate the dense clump structure to reach the deep particles inside. As a result, the fertilizer inside the clumps cannot be effectively activated, the nutrient crystal structure is not modified, and the insoluble nutrients remain in a solidified state, rendering the enhancement effect essentially ineffective. Ultimately, this results in uneven synergistic effects among fertilizers of the same batch, significantly increasing the dispersion of finished fertilizer effects. The nutrient release efficiency of the unenhanced internal particles after being applied to the soil is low, failing to achieve the expected goal of reducing dosage and increasing efficiency. Summary of the Invention

[0003] In view of the problem that fertilizers in existing technologies tend to clump together, which leads to a decrease in the synergistic effect, a spectral fertilizer synergistic device is proposed.

[0004] This application provides a spectral fertilizer enhancement device, the purpose of which is to break up clumps of fertilizer so that the fertilizer remains in granular form and improves the fertilizer enhancement effect.

[0005] The technical solution of the present invention is as follows: a spectral fertilizer enhancement device, including an enhancement box, an inlet pipe provided on the enhancement box, an outlet pipe provided at the bottom of the enhancement box, and a screening and crushing unit provided inside the enhancement box; The screening and crushing unit includes a screening component and a crushing component disposed inside the enhancement box. The screening component includes a conveying component and a screening component disposed inside the enhancement box. The screening component is provided with a reset component and a movable component. The screening component is used to screen out clumps of fertilizer, and the crushing component crushes the clumps of fertilizer. The conveying assembly includes a conveying cylinder disposed inside the enhancement box, and an auger shaft disposed inside the enhancement box. The auger shaft extends to the inside of the conveying cylinder, and auger blades are disposed on the auger shaft. The outer wall of the auger blades is in contact with the inner wall of the conveying cylinder. A drive motor is disposed on the top of the enhancement box, and the output shaft of the drive motor is fixedly connected to the top of the auger shaft.

[0006] Furthermore, the screening assembly includes an outer ring disposed inside the enhancement box, a screening plate disposed inside the outer ring, an inner ring disposed outside the conveying cylinder, and the screening plate being movably sleeved on the outer side of the inner ring.

[0007] Furthermore, the reset assembly includes two symmetrically distributed grooves on the outer ring, a slider is provided inside the groove, a reset spring is provided between the slider and the inner wall of the groove, and the slider is fixedly connected to the screening plate.

[0008] Furthermore, the movable component includes a protrusion disposed on the inner side of the screening plate, and an inclined groove, a vertical groove and an arc groove connected end to end are provided on the inner ring. A one-way wedge block is provided at the connection between the arc groove and the inclined groove. The protrusion is slidably connected to the inner side of the inclined groove, the vertical groove and the arc groove respectively.

[0009] Furthermore, the crushing component includes a crushing assembly disposed inside the enhancement box, and a driving assembly disposed outside the enhancement box; The crushing assembly includes a fixed plate disposed inside the enhancement box, a movable plate disposed on the top of the fixed plate inside the enhancement box, a number of crushing rods disposed in a circular array on the movable plate, the crushing rods penetrating the fixed plate, a guide wheel disposed on the fixed plate, a rotating ring disposed on the screening plate, and two steel wire ropes disposed symmetrically on the movable plate, the end of the steel wire rope away from the movable plate passing around the guide wheel and fixedly connected to the rotating ring.

[0010] Furthermore, the drive assembly includes an arc-shaped frame disposed on the outside of the enhancement box, an arc-shaped block disposed on the inner side of the arc-shaped frame, a through groove disposed on the enhancement box, a fixing strip disposed on the inner side of the through groove, the fixing strip fixing the outer ring to the arc-shaped block, an arc-shaped spring disposed between the arc-shaped block and the inner wall of the arc-shaped frame, a reciprocating spiral groove disposed on the top outer wall of the auger shaft, a nut disposed on the auger shaft at the reciprocating spiral groove section, the nut being slidably connected to the enhancement box, an L-shaped rod disposed on the nut, the bottom of the L-shaped rod abutting against the top of the arc-shaped block.

[0011] Furthermore, one end of the arc-shaped block is provided with a first inclined surface, and the L-shaped rod is slidably connected to the first inclined surface.

[0012] Furthermore, a frustum-shaped cover is provided on the top outer wall of the conveying cylinder.

[0013] Furthermore, a frustum-shaped cylinder is provided inside the enhancement box.

[0014] Furthermore, an LED spectrum lamp is installed on the inner side of the enhancement box at the bottom of the frustum-shaped cylinder.

[0015] The beneficial effects of this invention are: Driven by a auger shaft, the outer ring reciprocates, working in conjunction with the inner ring inclined track and return spring to achieve a combined action of "rotation and downward movement + rapid upward vibration" of the screening plate, efficiently separating agglomerates from qualified fertilizer granules. Vibrating screening avoids screen clogging and accelerates the passage of qualified granules, ensuring continuous material flow. Separated agglomerates are concentrated at the edge of the screen plate, preventing them from mixing with mainstream material and entering the irradiation station. This prevents dense agglomerates from blocking light from internal particles, improving the efficiency blind spots of traditional feeding methods, ensuring uniform particle size of material entering the irradiation zone, and significantly improving the energy utilization rate and processing uniformity of spectral irradiation.

[0016] As the screening plate moves downward, the wire rope pulls the crushing rod back to avoid it; when the screening plate springs back to its original position, the crushing rod falls under its own weight, precisely crushing the clumps gathered at the edge of the screening plate. This structure only crushes the clumps screened out, without damaging qualified fertilizer granules, effectively reducing the generation of fine powder and maintaining the uniformity of the finished product particle size. The crushed material can be returned to the main process along with the screening to participate in spectral enhancement, which not only improves the utilization rate of raw materials, but also avoids the dead zones of enhancement inside the clumps, ensuring that all granules can receive sufficient irradiation activation, significantly improving the consistency and stability of the finished fertilizer effect.

[0017] Qualified fertilizer falls into a frustum-shaped cylinder, where it is evenly dispersed and falls under the guidance of a flow mechanism, forming a thin curtain of fertilizer of uniform thickness. The particles naturally tumble during their descent, working in conjunction with LED spectral lamps below to enhance irradiation efficiency. Compared to traditional static irradiation, the thin curtain structure avoids mutual shading between particles, allowing photons to fully act on each fertilizer particle. Particle tumbling ensures full-surface illumination, solving the problem of incomplete activation from single-sided irradiation. This structure significantly improves the uniformity of nutrient crystal modification, effectively enhancing nutrient solubility and bioactivity. Combined with a circulating transport structure, multiple irradiations can be achieved, further ensuring the treatment effect and quality stability of the spectral enhancement process.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Example 1, referring to Figures 1-7 This invention provides a first embodiment of a spectral fertilizer enhancement device, comprising an enhancement box 1, an inlet pipe 11 fixedly connected to the enhancement box 1, an outlet pipe 12 fixedly connected to the bottom of the enhancement box 1, and a screening and crushing unit installed inside the enhancement box 1. The screening and crushing unit includes a screening component and a crushing component installed inside the enhancement box 1. The screening component includes a conveying component 2 and a screening component 3 installed inside the enhancement box 1. A reset component 4 and a movable component 5 are installed on the screening component 3. The sub-components are used to screen out clumps of fertilizer, and the crushing component crushes the clumps of fertilizer. The conveying assembly 2 includes a conveying cylinder 21 fixedly connected to the inside of the enhancement box 1. An auger shaft 22 is also rotatably connected to the inside of the enhancement box 1. The auger shaft 22 extends to the inside of the conveying cylinder 21. An auger blade 23 is fixedly connected to the auger shaft 22. The outer wall of the auger blade 23 fits against the inner wall of the conveying cylinder 21. A drive motor 24 is also fixedly connected to the top of the enhancement box 1. The output shaft of the drive motor 24 is fixedly connected to the top of the auger shaft 22.

[0022] Specifically, the fertilizer to be mixed is added to the enhancement box 1 through the feed pipe 11. The drive motor 24 is started, driving the auger shaft 22 to rotate, causing the auger blades 23 to rotate inside the conveying cylinder 21. The fertilizer in the enhancement box 1 accumulates at the bottom of the conveying cylinder 21. The auger blades 23 guide the fertilizer into the inside of the conveying cylinder 21, where it is then conveyed upwards. Afterwards, the fertilizer falls from the top of the conveying cylinder 21, and this cycle continues, mixing the fertilizer. The fertilizer is then screened by the screening component 3 to remove any clumps. Finally, the clumps are crushed by the crushing component. Screening to remove clumps before crushing is a crucial pre-process to ensure a uniform and stable spectral enhancement effect. Spectral enhancement relies on photons directly acting on the surface of fertilizer particles. The effective irradiation depth is limited; tightly packed clumps can block internal particles, creating large-area enhancement blind spots, leading to significant differences in nutrient activation levels within the same batch of material. Screening and separating agglomerates prevents blind-zone materials from entering the irradiation station, ensuring uniform light exposure for mainstream materials and improving irradiation energy utilization. Crushing agglomerates to the required particle size and then refluxing them completely eliminates internal dead zones for synergistic enhancement, allowing all fertilizer particles to fully receive spectral irradiation activation. This significantly improves the conversion rate of available nutrients and the consistency of finished fertilizer efficacy, ensuring the processing precision and quality stability of the spectral synergistic process.

[0023] Reference Figure 6 The screening assembly 3 includes an outer ring 31 rotatably connected to the inner side of the enhancement box 1, a screening plate 32 slidably connected to the inner side of the outer ring 31, an inner ring 33 fixedly sleeved on the outer side of the conveying cylinder 21, and the screening plate 32 movably sleeved on the outer side of the inner ring 33.

[0024] Specifically, the fertilizer coming out of the conveyor cylinder 21 will fall onto the screening plate 32. Under the action of the screening plate 32, the fertilizer is screened. Furthermore, the screening plate 32 slides up and down on the inner side of the outer ring 31, which has the effect of vibrating the screening plate 32, making it easier and faster for the fertilizer on the screening plate 32 to fall, thereby improving efficiency.

[0025] Reference Figure 6 The reset component 4 includes two symmetrically distributed grooves on the outer ring 31. A slider 41 is slidably connected to the inner side of the groove. A reset spring 42 is fixedly connected between the slider 41 and the inner wall of the groove. The slider 41 is fixedly connected to the screening plate 32.

[0026] Specifically, when the screening plate 32 is subjected to force and slides downward, the slider 41 will slide downward inside the groove and squeeze the return spring 42. When the screening plate 32 is not subjected to force, under the action of the return spring 42, the screening plate 32 slides upward quickly and vibrates, causing the fertilizer on the screening plate 32 to vibrate and fall.

[0027] Reference Figure 6 and Figure 7The active component 5 includes a protrusion 51 fixedly connected to the inner side of the screening plate 32. The inner ring 33 is provided with an inclined groove 52, a vertical groove 53 and an arc groove 54 connected end to end. A one-way wedge block 55 is fixedly connected at the connection between the arc groove 54 and the inclined groove 52. The protrusion 51 is slidably connected to the inner side of the inclined groove 52, the vertical groove 53 and the arc groove 54 respectively.

[0028] Specifically, the outer ring 31 rotates, and under the action of the slider 41 and the chute, it drives the screening plate 32 to rotate, causing the protrusion 51 to slide inside the inclined groove 52. This causes the screening plate 32 to rotate and move downwards simultaneously. When the screening plate 32 rotates, it rotates the clumps of fertilizer at the top of the screening plate 32 to the top edge of the screening plate 32. As the screening plate 32 moves downwards, it compresses the return spring 42. When the protrusion 51 moves to the inside of the vertical groove 53, under the action of the return spring 42 and the vertical groove 53, the protrusion 51 slides upwards inside the vertical groove 53, driving the screening plate 32 to move upwards. The outer ring 31 rotates in the opposite direction to reset, causing the protrusion 51 to slide inside the arc groove 54 and slide past the one-way wedge block 55, re-entering the inside of the inclined groove 52. This reciprocating motion drives the screening plate 32 to rotate downwards and then rapidly move upwards and vibrate.

[0029] Example 2, refer to Figure 8 and Figure 9 This is the second embodiment of the present invention, which differs from the first embodiment in that: the crushing component includes a crushing assembly 6 installed inside the enhancement box 1, and a driving assembly 7 is installed outside the enhancement box 1; the crushing assembly 6 includes a fixed plate 61 fixedly connected to the inside of the enhancement box 1, a movable plate 62 slidably connected to the top of the fixed plate 61 inside the enhancement box 1, a plurality of crushing rods 63 fixedly connected in a circular array on the movable plate 62, the crushing rods 63 penetrating the fixed plate 61, a guide wheel 64 fixedly connected to the fixed plate 61, a rotating ring 65 rotatably connected to the screening plate 32, and two steel wire ropes 66 fixedly connected in a symmetrical distribution on the movable plate 62, the end of the steel wire rope 66 away from the movable plate 62 passing around the guide wheel 64 and fixedly connected to the rotating ring 65.

[0030] Specifically, when the screening plate 32 moves downward, it drives the rotating ring 65 downward. Under the action of the wire rope 66, the movable plate 62 is pulled, and the guide wheel 64 rotates, so that the position of the wire rope 66 does not shift. This causes the crushing rod 63 to slide upward on the fixed plate 61, clearing the clumps of fertilizer stuck between the crushing rods 63. When the screening plate 32 moves upward, the wire rope 66 is loosened. Under the action of the gravity of the movable plate 62, the crushing rod 63 extends out of the fixed plate 61 and abuts against the top of the screening plate 32, crushing the fertilizer at the top edge of the screening plate 32.

[0031] Reference Figure 9The drive assembly 7 includes an arc-shaped frame 71 fixedly connected to the outside of the enhancement box 1, an arc-shaped block 72 slidably connected to the inside of the arc-shaped frame 71, a through groove on the enhancement box 1, a fixing strip slidably connected to the inside of the through groove, the fixing strip fixing the outer ring 31 to the arc-shaped block 72, an arc-shaped spring 73 fixedly connected between the arc-shaped block 72 and the inner wall of the arc-shaped frame 71, a reciprocating spiral groove on the top outer wall of the auger shaft 22, a nut 74 threadedly connected to the auger shaft 22 in the reciprocating spiral groove section, the nut 74 slidably connected to the enhancement box 1, an L-shaped rod 75 fixedly connected to the nut 74, the bottom of the L-shaped rod 75 abutting against the top of the arc-shaped block 72.

[0032] Specifically, when the auger shaft 22 rotates, the reciprocating spiral groove causes the nut 74 to slide downwards on the auger shaft 22, driving the L-shaped rod 75 to move downwards and press against the arc-shaped block 72. This causes the arc-shaped block 72 to slide inside the arc-shaped frame 71, compressing the arc-shaped spring 73 and causing the fixing strip to slide inside the through groove, thus rotating the outer ring 31 inside the enhancement box 1. When the nut 74 slides upwards on the auger shaft 22, the arc-shaped block 72 slides back to its original position inside the arc-shaped frame 71 under the action of the arc-shaped spring 73, causing the outer ring 31 to rotate back to its original position. The remaining structure is the same as in Embodiment 1.

[0033] Example 3, referring to Figure 9 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: one end of the arc-shaped block 72 is provided with a first inclined surface, and the L-shaped rod 75 is slidably connected to the first inclined surface.

[0034] Specifically, the L-shaped rod 75 moves downwards, squeezing the arc-shaped block 72, and under the action of the first inclined surface, the arc-shaped block 72 is displaced.

[0035] Reference Figure 3 and Figure 4 A frustum cover is fixedly connected to the top outer wall of the conveyor cylinder 21.

[0036] Specifically, under the action of the truncated cone cover, the fertilizer inside the conveying cylinder 21 is evenly distributed on the screening plate 32 away from the inner ring 33, preventing the fertilizer from falling from the screening plate 32 and the inner ring 33.

[0037] Reference Figure 3 , Figure 4 and Figure 10 A frustum cylinder 8 is fixedly connected to the inner side of the enhancement box 1.

[0038] Specifically, the fertilizer falling from the screening plate 32 will land inside the frustum cylinder 8. Under the action of the frustum cylinder 8, the fertilizer falls evenly, forming a material curtain. The fertilizer rotates during the falling process, which improves the subsequent synergistic effect.

[0039] Reference Figure 3 and Figure 4 An LED spectrum lamp 9 is fixedly connected to the bottom of the frustum-shaped cylinder 8 on the inner side of the enhancement box 1.

[0040] Specifically, the falling fertilizer undergoes enhanced efficiency under the illumination of LED spectral lamp 9. Specific wavelength photons are emitted, irradiating the fertilizer and altering the nutrient crystal structure and bond energy, thereby improving nutrient solubility and bioactivity, and increasing fertilizer utilization. The remaining structure is the same as in Example 2.

[0041] Based on embodiments 1-3, the working principle of the present invention is as follows: The drive motor 24 is started, causing the auger shaft 22 to rotate. Under the action of the auger blades 23, the fertilizer at the bottom of the inner side of the enhancement box 1 enters the conveying cylinder 21 and is conveyed upwards. Afterwards, the fertilizer is discharged from the top outlet of the conveying cylinder 21 and falls onto the top of the screening plate 32. Under the action of the screening plate 32, the fertilizer is screened. The auger shaft 22 rotates, and under the action of the reciprocating spiral groove, the nut 74 slides up and down on the auger shaft 22, driving the L-shaped rod 75 to move. This causes the arc-shaped block 72 to slide inside the arc-shaped frame 71, compressing the arc-shaped spring 73, causing the outer ring 31 to rotate, driving the screening plate 32 to rotate. This causes the protrusion 51 to slide inside the inclined groove 52, driving the screening plate 32 to rotate and move downwards. Then, under the action of the vertical groove 53, the protrusion 51 drives the screening plate 32 to move rapidly upwards, generating vibration, causing the fertilizer on the screening plate 32 to fall rapidly. As the screening plate 32 moves downward, it drives the rotating ring 65 downward, tightening the wire rope 66 and causing the movable plate 62 to move upward. This causes the crushing rod 63 to slide upward, clearing the clumps of fertilizer between the crushing rods 63. As the screening plate 32 moves upward, the wire rope 66 is loosened. Under the influence of gravity, the movable plate 62 moves downward, causing the crushing rod 63 to extend out of the fixed plate 61 and contact the top of the screening plate 32, crushing the clumps of fertilizer at the top of the screening plate 32. The falling fertilizer enters the inner side of the frustum cylinder 8, forming a ring of material curtain. The fertilizer itself is still rotating, and under the action of the LED spectrum lamp 9, the fertilizer is irradiated, thus improving fertilizer utilization.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
