Description

Technical Field

[0001] This utility model relates to the field of bio-organic fertilizer production technology, specifically a fermentation liquid spraying mechanism and a bio-organic fertilizer production device containing the mechanism. Background Technology

[0002] A bio-organic fertilizer production device is an industrialized complete set of equipment that transforms organic waste such as livestock and poultry manure and straw into stable, harmless products rich in specific functional microorganisms through a series of processes including pretreatment, aerobic fermentation, aging, blending and adding bacteria, granulation and packaging. It achieves the resource utilization, harmlessness and functionalization of waste through microbial transformation. The fermentation tank is the core reaction equipment for realizing the bio-conversion of organic materials. When the fermentation tank is in use, in order to accelerate the decomposition of organic matter, generate high temperature to achieve harmlessness, uniformly regulate the humidity of materials, and ensure consistent and efficient fermentation quality, fermentation liquid needs to be sprayed into the fermentation tank.

[0003] A straw fertilizer fermentation device described in patent CN222556848U includes a protective cylinder and a fermentation liquid supply component. The protective cylinder has an inlet and a outlet. An internal stirring and spraying mechanism is installed within the protective cylinder. This mechanism includes a spraying component with a central shaft that penetrates the top of the protective cylinder and extends into its interior. Multiple stirring rods are fixedly connected at equal intervals to the surface of the central shaft inside the protective cylinder. The stirring rods are hollow and connected to the central shaft. This invention relates to the field of straw fertilizer fermentation technology. The straw fertilizer fermentation device redesigns the stirring components, allowing the fermentation liquid to be sprayed out through the newly designed spraying component. The spraying component is located inside the straw, enabling faster penetration of the fermentation liquid. Simultaneously, rotation ensures thorough penetration while also completing the stirring operation, improving the device's practicality.

[0004] In the aforementioned patent, the spray head mounted on the stirring rod enables directional spraying of the fermentation liquid. The spray head and stirring rod are typically connected by welding or threaded connections. However, when the spray head needs replacement or maintenance due to blockage or wear, welding, while ensuring connection strength, requires destructive disassembly of the stirring rod. Threaded connections allow for disassembly and assembly, but under long-term stirring vibration and the corrosive effects of the fermentation liquid, the threads are prone to rust or seizing, making disassembly and assembly difficult. To facilitate convenient maintenance of the spray head, this patent provides a fermentation liquid spraying mechanism and a bio-organic fertilizer production device containing this mechanism, eliminating the drawbacks of existing devices.

The input end of the water pump is fixedly connected to a water tank via a flexible hose. Multiple connecting sleeves 12 are vertically and equidistantly fixedly connected to the outer wall of the transmission rod 4. Two stirring rods 5 are symmetrically arranged on the outer sides of each connecting sleeve 12. The connecting sleeves 12 are slidably fitted onto the outer walls of the two stirring rods 5. Multiple spray heads are symmetrically installed. A support box 3 is rotatably sleeved on the outer wall of the transmission rod 4. A drive motor 7 is installed on one side of the support box 3. A bevel gear ring 10 is fixedly connected to the outer wall of the transmission rod 4. The bevel gear ring 10 is located inside the support box 3. A bevel gear 9 is meshed on the outer wall of the bevel gear ring 10. The bevel gear 9 is driven by the output end of the drive motor 7. A cleaning scraper 11 is fixedly connected to the bottom end of the transmission rod 4. The cleaning scraper 11 is C-shaped and fits against the inner wall of the fermentation tank 1. The stirring rod 5 is located inside the cleaning scraper 11. A disassembly and assembly module for easy disassembly and assembly of the stirring rod 5 is provided on the transmission rod 4. The disassembly and assembly module includes: two docking plugs 205 symmetrically installed inside the connecting sleeve 12, a transmission rod 4 located between the two docking plugs 205, the outer wall of the two docking plugs 205 away from the transmission rod 4 being frustoconical, two stirring rods 5 being slidably sleeved on the outer wall of the two docking plugs 205 respectively, the connecting sleeve 12 having a first infusion port at the port of the docking plug 205, the transmission rod 4 having a second infusion port at the port of the first infusion port, and a sealing ring being fixedly connected at the joint of the docking plug 205 and the stirring rod 5; It also includes a fermentation tank 1, with a sealing cover 8 installed at the top of the fermentation tank 1.

Afterwards, the multiple stirring rods 5 can be locked and fixed simultaneously by the disassembly and assembly module, effectively preventing the stirring rod 5 from automatically falling off during use. When the material is being stirred, the first electric valve is opened by the controller and the material is discharged into the inner cavity of the fermentation tank 1 through the feed pipe. At this time, the drive motor 7 is started to drive the bevel gear 9 to rotate. At the same time, the bevel gear ring 10 drives the transmission rod 4 to rotate under the meshing of the bevel gear 9.

The connecting sleeve 12 is provided with a support assembly for supporting the stirring rod 5; The limit slide bar 209 is provided with a reset component for pushing the limit baffle 208 to reset; The transmission rod 4 is equipped with a limiting component for pressing and limiting the limiting slide bar 209; The reset component is a spring 2010 sleeved on the outer wall of the limiting slide bar 209. One end of the spring 2010 contacts the inner wall of the connecting sleeve 12, and the other end of the spring 2010 contacts the outer wall of the limiting baffle 208. Through the cooperation of the positioning component and the reset component, the stirring rod 5 can be easily engaged and positioned. In one embodiment, such as Figures 2-5As shown, the support assembly includes two support plates 207 symmetrically fixedly connected to the outer wall of the connecting sleeve 12. The two support plates 207 are respectively located below the two stirring rods 5. The outer walls of the two stirring rods 5 are fixedly connected to the mating frame 206. The vertical cross section of the mating frame 206 is C-shaped. The mating frame 206 is slidably fitted onto the outer wall of the support plate 207. Through the mutual cooperation between the mating frame 206 and the support plate 207, the stirring rods 5 can be limited and supported. In one embodiment, such as Figures 2-5 As shown, the limiting assembly includes: multiple lifting pressure rings 203 vertically and equidistantly slidably sleeved on the outer wall of the transmission rod 4; the multiple lifting pressure rings 203 are interleaved with multiple connecting sleeves 12; the multiple lifting pressure rings 203 are in contact with the upper surface of the multiple connecting sleeves 12; the lifting pressure rings 203 are in contact with the upper surface of the limiting slide rod 209; two connecting pull rods 202 are symmetrically arranged on the outer side of the transmission rod 4; the multiple lifting pressure rings 203 are all fixedly connected to the outer wall of the two connecting pull rods 202; and the multiple connecting sleeves 12 are all slidably sleeved on the outer wall of the two connecting pull rods 202. A locking assembly is provided on the transmission rod 4; The locking assembly includes: a connecting collar 201 that slides onto the outer wall of the transmission rod 4. The connecting collar 201 is located above multiple connecting sleeves 12. The connecting collar 201 is fixedly connected to the top of a lifting pressure ring 203. A knurled bolt 204 is provided on the outer side of the connecting collar 201. The knurled bolt 204 passes through the connecting collar 201 to the interior of the transmission rod 4. The knurled bolt 204 is threadedly connected to the connecting collar 201. Two positioning slots for inserting the knurled bolt 204 are vertically and equidistantly provided on the outer wall of the transmission rod 4. Through the cooperation of the limiting assembly and the locking assembly, multiple stirring rods 5 can be locked and fixed simultaneously, effectively preventing the stirring rods 5 from automatically falling off during use.

[0024] The above embodiments disclose a fermentation liquid spraying mechanism and a bio-organic fertilizer production device containing the mechanism. In use, the stirring rod 5 is pushed to make the docking sleeve 206 fit onto the top outer wall of the support plate 207. At the same time, the docking sleeve 206 slides along the outer wall of the support plate 207 until one end of the stirring rod 5 is inserted into the interior of the connecting sleeve 12. At this time, the stirring rod 5 fits onto the outer wall of the docking plug 205, and the docking plug 205 is sealed to the stirring rod 5 through the sealing rubber ring. During this process, the positioning block 2011, under the pressure of the outer wall of the stirring rod 5, pushes the limiting slide rod 209 along the inner wall of the connecting sleeve 12 through the limiting baffle 208. At this time, the limiting baffle 208 retracts by moving the compression spring 2010. When the stirring rod 5 contacts the inner wall of one side of the connecting sleeve 12, the spring 2010 pushes the limiting baffle 208 by rebounding, causing the positioning block 2011 to be inserted into the interior of the stirring rod 5, thereby conveniently locking and positioning the stirring rod 5. Then, rotate the knurled bolt 204 to separate it from a positioning slot, and then push the connecting collar 201 to slide along the outer wall of the transmission rod 4. At this time, a lifting pressure ring 203 is pushed synchronously by the connecting collar 201, and multiple lifting pressure rings 203 move synchronously by the connecting rod 202 under the push of a lifting pressure ring 203 until multiple lifting pressure rings 203 contact the upper surface of multiple connecting sleeves 12 respectively. This can limit and block the limiting slide rod 209. Then, rotate the knurled bolt 204 to insert it into the interior of another positioning slot. This can lock multiple lifting pressure rings 203 synchronously and effectively prevent the stirring rod 5 from falling off automatically during use. When the material is stirred, the first electric valve is opened by the controller and the material is discharged into the inner cavity of the fermentation tank 1 through the feed pipe. At this time, the drive motor 7 is started to drive the bevel gear 9 to rotate. At the same time, the bevel gear ring 10 drives the transmission rod 4 to rotate along the inner wall of the support box 3 and the sealing cover plate 8 under the meshing drive of the bevel gear 9. At this time, the infusion pipe 6 is kept stationary along the inner wall of the transmission rod 4 through the limit ring. Meanwhile, the connecting sleeve 12 and the cleaning scraper 11 rotate under the drive of the transmission rod 4. At this time, the stirring rod 5 stirs the material under the drive of the connecting sleeve 12. During this process, when it is necessary to spray the fermentation liquid, the water pump is started to transport the fermentation liquid in the water tank to the inner cavity of the transmission rod 4 through the infusion pipe 6. At the same time, through the first infusion port, the second infusion port and the docking plug 205, the fermentation liquid can be transported to the inner cavities of multiple stirring rods 5 respectively, and the material in the stirring process can be sprayed through multiple spray heads. When the material has finished fermenting, the second electric valve is opened by the controller, so that the fermented material can be discharged through the discharge pipe. When the spray head needs maintenance, the above operation is reversed to facilitate the disassembly of the stirring rod 5, thereby further improving the efficiency of spray head maintenance.

[0025] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
