Description

Technical Field

[0001] This invention relates to the field of fertilizer fermentation preparation technology, specifically a fertilizer manufacturing device utilizing agricultural waste. Background Technology

[0002] The fertilizer manufacturing equipment utilizing agricultural waste is a key piece of equipment for realizing the resource utilization of agricultural waste. It can efficiently process various agricultural wastes such as straw, livestock and poultry manure, substandard fruits and vegetables, and mushroom residue. Through standardized core processes such as crushing, screening, and spraying fermentation liquid, it completes the large-scale preparation of organic fertilizer. First, the equipment sends the collected agricultural waste into the crushing unit, where it is processed into 1-3 cm particles by a spiral crusher, breaking down the fibrous structure of the waste and creating favorable conditions for subsequent fermentation and decomposition. Materials with uniform particle size are screened out, and then a pre-prepared microbial fermentation liquid is evenly sprayed onto the surface of the material through a high-pressure spraying system. The fermentation liquid is rich in probiotics, organic acids, and other components, which can accelerate the decomposition of organic matter and inhibit the growth of harmful bacteria. After spraying, the material undergoes aerobic fermentation within the equipment, maintaining a high temperature above 55℃ for no less than 5 days to achieve harmless treatment.

[0045] This invention provides, through improvements, a fertilizer manufacturing apparatus utilizing agricultural waste, such as... Figures 1-10 As shown, including;

[0046] The powder screening equipment 1 includes a feed bin 101 and a screening bin 102 connected together; the screening bin 102 is used to crush, mix and screen agricultural waste.

[0047] The linkage mechanism 2 is rotatably disposed on one side of the screening chamber 102, including a stirring plate 205 and a scraping plate 206; the stirring plate 205 is rotatably disposed inside the screening chamber 102, and is used to stir and spread the crushed agricultural waste; the scraping plate 206 is rotatably disposed outside the screening chamber 102, and is used to clean the debris attached to the outer wall of the screening chamber 102.

[0048] The spraying mechanism 3 is mounted on the linkage mechanism 2; it includes multiple nozzle assemblies 302 mounted on the mixing plate 205; when the linkage mechanism 2 rotates, the nozzle assemblies 302 and the mixing plate 205 cooperate to mix and spray fermentation liquid on the crushed agricultural waste.

[0049] This powder screening equipment 1 consists of a feed hopper 101 and a screening hopper 102 connected together. Its function is to achieve centralized feeding and integrated pretreatment of agricultural waste. The feed hopper 101 serves as the feeding carrier, which can centrally collect various agricultural wastes such as straw, livestock and poultry manure, and mushroom residue, ensuring that the materials are stably and continuously transported to the screening hopper 102. The screening hopper 102 is the core pretreatment area, integrating four major functions: crushing, mixing, screening, and spraying, effectively improving processing efficiency.

[0050] The linkage mechanism 2 is rotatably installed on one side of the screening chamber 102. It drives the mixing plate 205 and the scraper plate 206 to operate synchronously with a single power source, achieving coordinated operation of internal mixing and scattering, and external debris removal. The mixing plate 205, located inside the screening chamber 102, rotates with the linkage mechanism to thoroughly mix and scatter the pulverized material. The scraper plate 206, located outside the screening chamber 102, rotates synchronously to scrape away material debris adhering to the chamber walls in real time, preventing debris from accumulating and clogging the screening pores.

[0051] The spraying mechanism 3 is attached to the linkage mechanism 2 to achieve synchronous spraying during mixing. Relying on the rotational power of the linkage mechanism 2, the nozzle assembly 302 moves synchronously with the mixing plate 205, eliminating the need for a separate spraying drive structure. Multiple nozzle assemblies 302 are evenly distributed on the mixing plate 205. When the linkage mechanism drives the mixing plate 205 to mix and scatter materials, the nozzle assembly 302 synchronously sprays fermentation liquid onto the dispersed materials, ensuring full contact and uniform fusion of the fermentation liquid with the materials. This avoids the problems of excessive or absent fermentation liquid in some areas due to uneven spraying in existing equipment.

[0052] See appendix Figure 3 -Appendix Figure 6 The screening chamber 102 has an opening on one side; symmetrical arc plates 106 are provided on the inner wall of the other side of the screening chamber 102; a crushing area is formed between the two arc plates 106; two crushing rollers 109 are rotatably arranged in the crushing area, and the screening chamber 102 crushes agricultural waste through the crushing rollers 109.

[0053] In this embodiment, the screening chamber 102 has an open design on one side, providing space for the installation and rotation of the linkage mechanism 2, while also cooperating with the internal working structure to ensure smooth material flow, accommodating both feeding and discharging. Agricultural waste entering the feed hopper 101 can enter the crushing area of ​​the screening chamber 102, avoiding material accumulation and blockage at the feed inlet.

[0054] The design of the internal arc plate 106 can prevent the crushing roller 109 from interfering with the rotation of the linkage mechanism 2.

[0055] In this embodiment, two symmetrical arc plates 106 are arc-shaped protrusions and are symmetrically distributed on the inner wall of the screening chamber 102. The two naturally form a partially enclosed crushing area that is adapted to the rotation trajectory of the crushing roller 109. The size of this area matches the diameter and spacing of the crushing roller 109, which can limit the entry of agricultural waste and prevent the material from deviating from the crushing area during the crushing process, thus avoiding insufficient crushing.

[0056] See appendix Figure 2 and attached Figure 6 A gear 110 is provided on the rotating shaft of the crushing roller 109; the two gears 110 mesh with each other;

[0057] The powder screening equipment 1 also includes a first drive source; the output end of the first drive source is connected to one of the rotating shafts.

[0058] In this embodiment, gears 110 are respectively installed on the rotating shaft of the crushing roller 109. The two gears 110 mesh with each other to form a stable gear transmission structure. Its working principle is to transmit power from one rotating shaft to the other rotating shaft through the meshing action between the gears, so as to realize the synchronous reverse rotation of the two crushing rollers 109.

[0059] The gear meshing transmission ensures that the two crushing rollers 109 rotate at the same speed but in opposite directions, with high transmission accuracy and stable power transmission, avoiding asynchronous speeds and chaotic rotation, and ensuring continuous and uniform shearing and compressing force on agricultural waste.

[0060] In this embodiment, the powder sieving device 1 is equipped with a first drive source, the output end of which is connected to the rotating shaft of one of the crushing rollers 109 to provide power for the entire crushing mechanism. During operation, the first drive source outputs rotational power, which directly drives the rotating shaft connected to it to rotate, and then drives the other rotating shaft to rotate synchronously through the meshing gear 110, realizing the coordinated operation of the two crushing rollers 109 driven by a single power source.

[0061] See appendix Figure 3 -Appendix Figure 7 Two arc plates 106 are fixedly provided with mounting plates 107 facing the opening side; a first mounting ring 112 is provided on the outer wall of the mounting plate 107;

[0062] The linkage mechanism 2 includes a sealing plate 201; the sealing plate 201 is rotatably disposed between the mounting plate 107 and the radial outer wall of the screening chamber 102; a second mounting ring 202 is disposed in the middle of the sealing plate 201; the sealing plate 201 is rotatably disposed in the first mounting ring 112 through the second mounting ring 202.

[0063] In this embodiment: two arc plates 106 are fixedly mounted with mounting plates 107 facing the opening side, so that the mounting plates 107 and the arc plates 106 form a stable integrated structure, which not only provides a reliable installation base for the linkage mechanism 2, but also limits and blocks the front end of the crushing area to prevent agricultural waste from splashing or leaking outward during the crushing process.

[0064] The outer wall of the mounting plate 107 is provided with a first mounting ring 112. The first mounting ring 112 serves as a fixed support base, providing a stable rotation positioning reference for the linkage mechanism 2, ensuring the coaxiality of subsequent rotating parts, avoiding eccentric shaking during rotation, ensuring stable cooperation between the linkage mechanism 2 and the powder screening equipment 1, and improving the overall structural strength and operational reliability, providing structural support for functions such as sealing, rotation, and spraying.

[0065] In this embodiment, the sealing plate 201 of the linkage mechanism 2 is rotatably disposed between the mounting plate 107 and the radial outer wall of the screening chamber 102, forming an annular sealing and shielding structure. Without affecting the rotation, the opening of the screening chamber 102 is sealed to prevent the leakage of materials, dust and fermentation liquid, ensure a clean working environment and avoid material waste.

[0066] A second mounting ring 202 is provided in the middle of the sealing plate 201. The second mounting ring 202 cooperates with the first mounting ring 112 to achieve a rotatable connection. The first mounting ring 112 is used as the central axis to perform stable circumferential rotation, ensuring smooth rotation.

[0067] See appendix Figure 2 and attached Figure 6 -Appendix Figure 7 A discharge hole 111 is provided on the radial outer wall of the screening chamber 102 facing the direction of gravity; an annular first gap 103 is provided between the feed chamber 101 and the screening chamber 102, the first gap 103 is used for the scraper 206 to pass through; the stirring plate 205 is fixedly installed on the inner wall of the sealing plate 201, the stirring plate 205 is inclined and abuts against the radial inner wall of the screening chamber 102; the scraper 206 is fixedly installed on the outer wall of the sealing plate 201 and abuts against the radial outer wall of the screening chamber 102.

[0068] In this embodiment, a discharge hole 111 is provided on the radial outer wall of the screening chamber 102 facing the direction of gravity, so as to realize the automatic discharge of qualified materials after crushing and screening by utilizing gravity. During operation, the qualified fine materials after being crushed by the crushing roller 109, stirred and screened by the turning plate 205, and sprayed will naturally converge to the bottom of the screening chamber 102 under their own gravity and be smoothly discharged through the discharge hole 111.

[0069] In this embodiment, an annular first gap 103 is provided between the feed bin 101 and the screening bin 102 to provide a dedicated movement channel for the scraper 206, ensuring that the scraper 206 does not interfere with the feed bin 101 and the screening bin 102 during rotation, and ensuring the smooth operation of the linkage mechanism 2.

[0070] In this embodiment: Since the scraper 206 is fixed to the outer wall of the sealing plate 201 and rotates synchronously with the sealing plate 201, the rotation trajectory will cover the radial outer wall of the screening chamber 102. The annular design of the first gap 103 is adapted to the rotation trajectory of the scraper 206, which just allows the scraper 206 to pass through the gap, avoiding collision or jamming between the scraper 206 and the bottom of the feed chamber 101 or the edge of the outer wall of the screening chamber 102, and protecting the equipment components from wear.

[0071] Meanwhile, the annular gap design does not affect the normal feeding of the feed bin 101 into the screening bin 102, achieving non-interference in feeding and unobstructed scraping, ensuring that the scraping operation and the feeding operation are carried out synchronously.

[0072] In this embodiment, the mixing plate 205 rotates synchronously with the sealing plate 201. It is inclined and abuts against the radial inner wall of the screening chamber 102. Through the scraping and mixing action during the rotation process, the material is uniformly mixed and fully screened, while also assisting in cleaning the accumulated material on the chamber wall.

[0073] The inclined design allows the turning plate 205 to generate an upward throwing force and a lateral pushing force on the material in the screening chamber 102 when it rotates, turning the material at the bottom to the top. The turning plate 205 abuts against the radial inner wall of the screening chamber 102, and can scrape off the material debris attached to the chamber wall in real time when it rotates, preventing the material from clumping and clogging the screening holes.

[0074] In this embodiment: the scraper 206 is fixed on the outer wall of the sealing plate 201 and abuts against the radial outer wall of the screening chamber 102. It rotates synchronously with the sealing plate 201 to scrape and clean the material debris attached to the outer wall of the screening chamber 102 in real time.

[0075] See appendix Figure 6 -Appendix Figure 7 The mixing plate 205 and the scraping plate 206 are respectively arranged; there is a second gap 207 between the mixing plate 205 and the scraping plate 206; the radial outer wall of the screening chamber 102 is located within the second gap 207; when the sealing plate 201 rotates, the mixing plate 205 mixes the raw materials that do not conform to the size and re-sprinkles them into the crushing area; when the mixing plate 205 rotates to the area of ​​the first gap 103, the scraping plate 206 shields the raw materials on the mixing plate 205 to prevent them from being scattered under the action of centrifugal force.

[0076] In this embodiment, the stirring plate 205 and the scraping plate 206 are arranged in a corresponding manner, forming a second gap 207 between them. The radial outer wall of the screening chamber 102 is located inside the second gap 207, so that the sealing plate 201, the stirring plate 205, the scraping plate 206 and the screening chamber 102 form an inner and outer nested integral fit structure.

[0077] This design allows the mixing plate 205 to operate inside the screening chamber 102 and the scraping plate 206 to operate outside the screening chamber 102. The two share the rotational power of the sealing plate 201, achieving synchronous operation without interference.

[0078] In this embodiment: when the sealing plate 201 rotates, the stirring plate 205 simultaneously performs a circular motion, continuously stirring, lifting, and scattering large pieces of raw material inside the screening chamber 102 that do not meet the size requirements. During the rotation, the stirring plate 205 generates an upward thrust, which lifts up the unqualified material that has settled at the bottom of the chamber and sends it back to the crushing area where the crushing roller 109 is located, so that the insufficiently crushed raw material is subjected to shearing action again until it reaches the qualified particle size.

[0079] In this embodiment: when the stirring plate 205 rotates with the sealing plate 201 to the position of the first gap 103, the scraper plate 206 moves synchronously to the corresponding outer position, forming a blocking and limiting effect on the raw materials on the stirring plate 205. During the high-speed rotation of the stirring plate 205, centrifugal force is generated, which can easily cause the raw materials to drift outward at the first gap 103. The scraper plate 206 can form a blocking surface on the outside, blocking the raw materials that are about to drift back into the screening chamber 102 and fall into the crushing area.

[0080] See appendix Figure 3 -Appendix Figure 7 The first mounting ring 112 has a track 113 on its radial outer wall; the second mounting ring 202 has an annular groove 203 on its radial inner wall, and the track 113 is rotatably disposed in the annular groove 203; a gear ring 204 is also installed on the radial inner wall of the second mounting ring 202; the powder screening equipment 1 also includes a second drive source, the output end of which is connected to the gear ring 204 for transmission; the second drive source is used to drive the linkage mechanism 2 to rotate.

[0081] In this embodiment: a track 113 is provided on the radial outer wall of the first mounting ring 112, and an annular groove 203 is provided on the radial inner wall of the second mounting ring 202. The track 113 is rotatably fitted into the annular groove 203, forming an annular rotatable fit structure.

[0082] A gear ring 204 is installed on the radial inner wall of the second mounting ring 202. The gear ring 204 is driven by the output end of the second drive source, which converts the power of the second drive source into the rotational power of the linkage mechanism 2, thereby achieving precise power transmission.

[0083] In this embodiment, the gear ring 204 adopts a ring structure and is coaxially fixed with the second mounting ring 202. It can evenly bear the force of the drive source, ensuring smooth and uniform power transmission and avoiding excessive local stress that could damage the components. At the same time, the gear ring 204 has high transmission precision, which can accurately control the rotation speed and direction of the linkage mechanism 2, adapting to the operation rhythm of crushing, mixing, and spraying.

[0084] See appendix Figure 6 -Appendix Figure 7 The spraying mechanism 3 includes a spray pipe 301 mounted on the stirring plate 205, and a nozzle assembly 302 connected to the spray pipe 301; multiple spray pipes 301 pass through the sealing plate 201 and are connected to a manifold pipe 303; the manifold pipe 303 is coaxially arranged with the sealing plate 201 and the screening chamber 102, and a rotary joint 304 is rotatably mounted on the liquid inlet end of the manifold pipe 303; the manifold pipe 303 is connected to an external liquid supply device through the rotary joint 304.

[0085] In this embodiment: the spray pipe 301 of the spraying mechanism 3 is fixedly installed on the stirring plate 205, and the nozzle assembly 302 is connected to the spray pipe 301. The principle is to transport the fermentation liquid to the nozzle assembly 302 through the spray pipe 301, and then atomize and spray it onto the crushed material through the nozzle assembly 302 to achieve full fusion of the fermentation liquid and the material.

[0086] The spray pipe 301 rotates synchronously with the stirring plate 205, which drives the nozzle assembly 302 to move synchronously with the stirring action, expanding the spraying range. Multiple nozzle assemblies 302 are evenly distributed on the spray pipe 301, atomizing the fermentation broth into fine droplets, resulting in more uniform spraying. Simultaneously, the fixed connection between the spray pipe 301 and the stirring plate 205 further enhances the stirring effect, achieving synchronous synergy between stirring and spraying. When the stirring plate 205 throws the material up, the nozzle assembly 302 sprays simultaneously, ensuring full contact between the fermentation broth and the dispersed material.

[0087] In this embodiment, multiple spray pipes 301 penetrate the sealing plate 201 and are connected to the manifold 303. The manifold 303 is coaxially arranged with the sealing plate 201 and the screening chamber 102. The principle is to realize the centralized transportation and diversion of the fermentation liquid, and ensure that the liquid supply of each spray pipe 301 is uniform and stable.

[0088] The manifold 303 serves as the main liquid delivery channel, collecting the fermentation broth supplied by the external liquid supply equipment and then distributing it evenly to each spray pipe 301. Its coaxial design ensures that the manifold 303 will not interfere with the screening chamber 102 or the sealing plate 201 when rotating synchronously with the sealing plate 201, while also ensuring that the rotation trajectory of each spray pipe 301 is consistent, further improving the uniformity of spraying.

[0089] In this embodiment, a rotary joint 304 is rotatably installed at the inlet end of the manifold 303. The manifold 303 is connected to the external liquid supply equipment through the rotary joint 304. The principle is to resolve the contradiction between the rotation of the manifold 303 and the fixed external liquid supply pipeline, thereby achieving continuous and stable delivery of the fermentation broth and avoiding pipeline entanglement and damage. Since the manifold 303 rotates synchronously with the sealing plate 201, while the pipeline of the external liquid supply equipment is fixed, the rotary joint 304 can achieve a sealed connection between the fixed end and the rotating end.

[0090] See appendix Figure 8 -Appendix Figure 10The nozzle assembly 302 includes an outer cylinder 305 and a starting plug 308; a plurality of spray holes 306 are provided on the radial outer wall of the outer cylinder 305; the starting plug 308 is slidably disposed inside the outer cylinder 305, and a spray channel 310 for communicating with the spray holes 306 is provided inside the starting plug 308; a telescopic groove 307 is provided inside the outer cylinder 305, and a return spring 309 is provided in the telescopic groove 307, and the return spring 309 is connected to the starting plug 308.

[0091] In this embodiment, the outer cylinder 305 of the nozzle assembly 302 serves as the core mounting carrier, with multiple spray holes 306 formed on its radial outer wall. This multi-hole layout enables uniform atomization and wide-area spraying of the fermentation liquid. The outer cylinder 305 is fixed to the spray pipe 301, receiving the fermentation liquid transported by the spray pipe and providing a stable mounting space for the starting plug 308 and the return spring 309.

[0092] In this embodiment, the starting plug 308 is slidably disposed inside the outer cylinder 305, and a spray channel 310 corresponding to the spray hole 306 is formed inside it. The principle is that by sliding the starting plug 308, the on / off control of the spray channel 310 and the spray hole 306 is realized, thereby controlling the spraying and stopping of the fermentation liquid and realizing precise control of the spraying. When the spray pipe 301 delivers the fermentation liquid, the fermentation liquid enters the outer cylinder 305 and generates a thrust on the starting plug 308, pushing the starting plug 308 to overcome the elastic force of the return spring 309 and slide along the outer cylinder 305 until the spray channel 310 is aligned and connected with the spray hole 306 on the outer cylinder 305. At this time, the fermentation liquid is sprayed out from the spray hole 306 through the spray channel 310.

[0093] When the liquid supply stops, the thrust disappears, the starter plug 308 is reset by the reset spring 309, the spray channel 310 and the spray hole 306 are misaligned, and the spray is shut off.

[0094] See appendix Figure 1 -Appendix Figure 10 The starting plug 308 has a conical surface 311 at one end facing the liquid inlet direction; a guide hood 104 is provided at the feed inlet of the feed bin 101; the powder screening equipment 1 also includes a dust removal device 105; the dust removal device 105 is connected to the feed bin 101; and the top of the arc plate 106 is provided with a flow guide 108 extending outward.

[0095] In this embodiment, the starting plug 308 is provided with a conical surface 311 at the end facing the liquid inlet direction. This conical surface structure can increase the area of ​​the fermentation liquid pressure, so that the liquid inlet pressure can more efficiently push the starting plug 308 to slide, thereby realizing the sensitive opening of the nozzle.

[0096] In this embodiment, a guide hood 104 is provided at the feed inlet of the feed bin 101 to guide and gather agricultural waste, so that the raw materials fall stably into the crushing area of ​​the screening bin 102 in a specified direction, avoiding splashing, spilling or accumulating of raw materials at the feed inlet.

[0097] In this embodiment, the dust removal device 105 is connected to the feed hopper 101. During the feeding and crushing process, it extracts the dust and fine debris generated inside in real time. The dust is collected and processed by negative pressure adsorption to prevent the dust from spreading outward from the feed inlet or equipment gaps, thus maintaining a clean production environment.

[0098] In this embodiment, the top of the arc plate 106 is provided with an outwardly extending guide portion 108, which can guide the falling material and accurately guide the raw material to the crushing area between the two crushing rollers 109, preventing the material from scattering outside the crushing area and causing escape or accumulation. The guide portion 108, together with the arc plate 106, forms a complete guiding structure, improving the material utilization rate.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and inventive features disclosed herein.
