Description

Technical Field

[0001] This utility model relates to the field of seedling equipment technology, specifically to a device for adding nutrients and anti-mold agents to wet seedling substrate blankets. Background Technology

[0002] In the wet seedbed treatment stage of seedling production, the effectiveness of adding seedling strengtheners and antifungal agents directly determines the quality of seedlings and the storage performance of the product. However, existing technologies still have persistent and difficult-to-overcome shortcomings. Current mainstream addition methods have significant limitations: some methods rely on manual operation, which is not only inefficient but also prone to imbalances in dosage and uneven coverage due to differences in human experience. Agents are often missed at the edges or deeper areas of the wet seedbed, while excessive addition in some areas can lead to waste. These shortcomings directly result in uneven action of seedling strengtheners, uneven seedling growth, and unstable seedling production. Simultaneously, insufficient coverage with antifungal agents makes the wet seedbeds susceptible to mold growth during storage, shortening the shelf life. Furthermore, existing methods suffer from low precision in agent control, high reliance on manual labor, and weak adaptability to large-scale production, hindering the standardization of seedling production. Therefore, we propose a nutrient and antifungal agent addition device for wet seedbed substrate mats. Utility Model Content

[0003] The purpose of this invention is to provide a nutrient and anti-mold agent addition device for wet seedling substrate mats. Through the coordinated design of the atomizing nozzle assembly driven by the robotic arm, combined with the stable transmission of the conveying mechanism, it solves the problems of low efficiency caused by manual operation, uneven action of seedling strengthening agents, uneven seedling growth, and unstable seedling raising effect; at the same time, insufficient coverage of anti-mold agent makes the wet mats prone to mold growth during storage, shortening the shelf life.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a nutrient and anti-mold agent addition device for a wet seedling substrate blanket, comprising a conveying mechanism and an atomizing nozzle assembly disposed at the outlet of the wet substrate blanket forming device. The conveying mechanism includes a drive wheel and a driven wheel mounted on a conveying frame, and a conveying motor. A conveyor belt is fitted onto the drive wheel and the driven wheel. The conveying motor drives the drive wheel to rotate via a transmission belt, thereby driving the drive wheel and the conveyor belt to transport the wet seedling substrate blanket.

[0005] The atomizing nozzle assembly is mounted on a robotic arm, which drives the atomizing nozzle assembly to spray seedling strengthening agent and anti-mold agent onto the wet seedling substrate blanket on the conveyor belt. The atomizing nozzle assembly provides a mixture of seedling strengthening agent and anti-mold agent through a liquid supply mechanism.

[0006] Preferably, the robotic arm is a six-axis robotic arm.

[0007] Preferably, the robotic arm includes a support, on which a crossbar is mounted. The crossbar is located above the conveyor belt. The atomizing nozzle assembly is mounted on the crossbar via a translation component and a lifting component. The translation component and the lifting component are used to adjust the position of the atomizing nozzle assembly relative to the wet seedling substrate mat.

[0008] Preferably, the translation component includes a screw mounted on a crossbar and a rotary motor. A slide is provided on the screw, and the rotary motor is used to drive the screw to rotate, thereby driving the slide to translate along the crossbar.

[0009] The lifting assembly includes a lifting rod, the upper end of which is mounted on a slide, and the lower end of which is connected to an atomizing nozzle assembly, wherein the atomizing nozzle assembly is a wide-angle atomizing nozzle.

[0010] Preferably, the atomizing nozzle assembly is connected to the liquid supply mechanism via a liquid supply pipe. The liquid supply mechanism is internally equipped with a seedling-strengthening agent mother liquor storage tank, a mold inhibitor mother liquor storage tank, and a mixing chamber. The seedling-strengthening agent mother liquor storage tank is used to supply the seedling-strengthening agent mother liquor to the mixing chamber, and the mold inhibitor mother liquor storage tank is used to supply the mold inhibitor mother liquor to the mixing chamber. The mixing chamber is also connected to a water pump for adding water. The liquid supply mechanism provides the atomizing nozzle assembly with a mixture of seedling-strengthening agent and mold inhibitor through the mixing chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention ensures stable transport of wet rice cakes through a conveying mechanism. A robotic arm drives an atomizing nozzle assembly that moves synchronously with the wet rice cakes, precisely initiating spraying when the cakes enter the designated area, avoiding the mismatch problems of traditional fixed sprayers. The atomizing nozzles spray the mixture provided by the supply mechanism in a fine mist, ensuring complete coverage of the wet rice cake surface without omissions, while also penetrating shallow areas. A uniformly distributed seedling-strengthening agent provides stable nutrition to the seedlings, improving growth uniformity and seedling quality. An anti-mold agent forms a comprehensive protective layer, disrupting conditions for mold growth and extending product shelf life. The equipment operates automatically without manual intervention, reducing operational errors and agent waste. Furthermore, the atomizing nozzle assembly is directly installed on the robotic arm, requiring no modification to the original conveying path, offering strong compatibility and adaptability to large-scale production.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The wet substrate blanket is produced using bio-enzymatic hydrolysis and fiber interweaving technology. This technology achieves the directional combination of bamboo fiber and straw cellulose with manure organic matter, forming a "carbon-nitrogen interlocking" mesh fiber interwoven structure. After bio-enzymatic hydrolysis, pulping, and filtration molding, the substrate blanket is directly retained in its wet state. The substrate blanket's specifications are designed to fit existing seedling and sowing equipment, requiring no modification to existing equipment for direct use. This makes it convenient, labor-saving, and efficient. Simultaneously, the wet substrate blanket exhibits excellent water absorption. Its unique "carbon-nitrogen interlocking" mesh fiber interwoven structure, with bamboo fiber and straw fiber as the framework combined with livestock and poultry manure organic matter, enhances the substrate blanket's physical stability, preventing it from easily disintegrating. It effectively absorbs and retains nutrients and water, reducing loss and providing a continuous and stable environment for seedling growth. The resulting seedlings have well-developed root systems, and key indicators such as seedling establishment rate and seedling vigor index are superior to those of traditional substrates, effectively improving seedling quality and the yield potential of subsequent crops.

[0021] like Figure 1 As shown, a nutrient and anti-mold agent addition device for a wet seedling substrate blanket includes a conveying mechanism and an atomizing nozzle assembly 9 set at the outlet of the wet substrate blanket forming device. The conveying mechanism includes a drive wheel 2 and a driven wheel 3 mounted on a conveying frame 1, and a conveying motor 5. A conveyor belt 4 is fitted on the drive wheel 2 and the driven wheel 3. The conveying motor 5 drives the drive wheel 2 to rotate through a transmission belt 6, thereby driving the drive wheel 2 and the conveyor belt 4 to transport the wet seedling substrate blanket.

[0022] The atomizing nozzle assembly 9 is mounted on the robotic arm 8. The robotic arm 8 is used to drive the atomizing nozzle assembly 9 to spray the seedling substrate mat wet blanks on the conveyor belt 4 with seedling strengthening agent and anti-mold agent. The atomizing nozzle assembly 9 provides the mixture of seedling strengthening agent and anti-mold agent through the liquid supply mechanism 7.

[0023] After the wet billet forming equipment produces wet billets, they directly enter the conveying mechanism located at the outlet. The conveyor motor 5 on the conveyor frame 1 drives the drive wheel 2 to rotate via the transmission belt 6. The drive wheel 2 and the driven wheel 3 work together to drive the conveyor belt 4, smoothly conveying the wet billets to the spraying area. At the same time, the liquid supply mechanism 7 pre-prepares a mixture of seedling strengthening agent and mildew inhibitor and continuously delivers it to the atomizing nozzle assembly 9. The atomizing nozzle assembly 9 is installed on the robotic arm 8. The robotic arm 8 moves the nozzle assembly synchronously according to the rhythm and position of the wet billet transmission. When the wet billet enters the preset spraying area, the atomizing nozzle assembly 9 automatically starts and evenly sprays the mixture onto the surface and shallow layer of the wet billet. After the addition of nutrients and mildew inhibitor is completed, the wet billet continues to be conveyed to the subsequent process by the conveyor belt 4.

[0024] The robotic arm 8 drives the nozzle assembly to move synchronously with the wet seed cake, avoiding the misalignment problem of traditional fixed spraying and ensuring that the agent only acts on the wet seed cake. The agent coverage is uniform, and the atomizing nozzle sprays the mixture into a fine mist, achieving no omissions on the surface and penetrating to the shallow layer of the wet seed cake, solving the drawbacks of localized agent deficiency or excess. Seedling raising and storage effects are improved, with the uniform seedling strengthening agent providing stable nutrition for the seedlings and the anti-mold agent forming a comprehensive protective layer. Fourthly, it has good compatibility and efficiency. The nozzle assembly is directly installed on the robotic arm 8 without modifying the original conveying structure. Automated operation reduces manual intervention and is suitable for large-scale production.

[0025] The robotic arm 8 includes a support, on which a crossbar 81 is mounted. The crossbar 81 is located above the conveyor belt 4. The atomizing nozzle assembly 9 is mounted on the crossbar 81 via a translation component and a lifting component. The translation component and the lifting component are used to adjust the position of the atomizing nozzle assembly 9 relative to the wet seedling substrate blanket.

[0026] The translation assembly includes a screw 84 mounted on a crossbar 81 and a rotary motor 83. A slide 85 is provided on the screw 84. The rotary motor 83 is used to drive the screw 84 to rotate, thereby driving the slide 85 to translate along the crossbar 81.

[0027] The lifting assembly includes a lifting rod 82, the upper end of which is mounted on a slide 85, and the lower end of which is connected to an atomizing nozzle assembly 9. The atomizing nozzle assembly 9 uses a wide-angle atomizing nozzle. Depending on the wet blank specifications (9-inch / 7-inch), 4-6 wide-angle fan-shaped atomizing nozzles (droplet diameter 50-80μm, coverage angle 120°) are configured. A low-pressure atomization design (working pressure 0.2-0.3MPa) is adopted to avoid high-pressure impact damaging the wet blank structure. A guide plate (PTFE material) is added to the nozzle outlet to guide the mist flow vertically downward to cover the wet blank, reducing lateral drift (increasing reagent utilization to over 95%).

[0028] When the conveying mechanism is in operation, the conveying motor 5 drives the drive wheel 2 and the conveyor belt 4 to smoothly transport the wet blanks to the spraying area. The robotic arm 8 is fixed by a support, and the crossbar 81 is mounted above the conveyor belt 4. When the wet blanks reach the designated position, the rotary motor 83 of the translation component starts, driving the screw 84 on the crossbar 81 to rotate, causing the slide 85 on the screw 84 to move along the crossbar 81, adjusting the horizontal position of the atomizing nozzle assembly 9. At the same time, the lifting rod 82 of the lifting component drives the atomizing nozzle assembly 9 to move up and down, precisely matching the height of the wet blanks. After the liquid supply mechanism 7 delivers the mixture of seedling strengthening agent and anti-mold agent to the atomizing nozzle assembly 9, the wide-angle atomizing nozzle atomizes and sprays the mixture. The guide plate guides the mist to vertically cover the wet blanks, completing the addition of nutrients and anti-mold agents.

[0029] The robotic arm 8 can also be replaced by a multi-axis robot arm. The selection of the robotic arm 8 is flexible, and it can be freely selected as a multi-axis robot arm 8 or a combination of a crossbar 81 and a lifting rod 82. The former directly adjusts the nozzle position through multi-axis coordination, while the latter achieves precise adjustment through the screw 84 of the translation component and the linkage of the lifting rod 82. Both can be adapted to different working scenarios.

[0030] like Figure 2 As shown, the atomizing nozzle assembly 9 is connected to the liquid supply mechanism 7 via the liquid supply pipe 10. The liquid supply mechanism 7 contains a seedling-strengthening agent mother liquor storage tank 71, a mold inhibitor mother liquor storage tank 72, and a mixing chamber 77. The seedling-strengthening agent mother liquor storage tank 71 supplies the seedling-strengthening agent mother liquor to the mixing chamber 77, and the mold inhibitor mother liquor storage tank 72 supplies the mold inhibitor mother liquor to the mixing chamber 77. A water pump 78 for adding water is also connected to the mixing chamber 77. The liquid supply mechanism 7 supplies the atomizing nozzle assembly 9 with a mixture of seedling-strengthening agent and mold inhibitor through the mixing chamber 77. Two 30L corrosion-resistant storage tanks (one for seedling-strengthening agent mother liquor and one for mold inhibitor mother liquor) are installed, each equipped with a level sensor (automatic alarm and replenishment when the level is low), and connected to the mixing chamber 77 via a metering pump (accuracy ±1mL / min). The mixing chamber 77 is equipped with a concentration sensor (detection range 0.5%-5%) and a flow meter. It automatically mixes the pesticides according to a preset ratio (e.g., seedling strengthener: antifungal agent: water = 1:0.5:20). After mixing, the pesticide solution is delivered to the spray execution module by the booster pump 79 (outlet pressure 0.2-0.3MPa) to ensure that the concentration deviation of each batch of pesticide solution is ≤±0.1%.

[0031] The seedling strengthening agent mother liquor storage tank 71 is connected to the mixing chamber 77 through the seedling strengthening agent mother liquor pipe 73 and the metering pump 75. The antifungal agent mother liquor storage tank 72 is connected to the mixing chamber 77 through the antifungal agent mother liquor pipe 74 and the metering pump 76. The mixing chamber 77 is connected to the supply pipe 10 through the booster pump 79.

[0032] At least one of the seedling strengthener mother liquor storage tank 71 and the mold inhibitor mother liquor storage tank 72 is equipped with an anti-sedimentation component. The anti-sedimentation component includes a stirrer 711 installed at the bottom of the tank and a stirring motor 710 that drives the stirrer 711 to rotate. A low-speed stirrer (50 r / min) is installed in the storage tank to avoid uneven concentration caused by the precipitation of trace elements in the seedling strengthener. The stirrer 711 is linked to the metering pump (stirring for 30 seconds before starting the metering pump).

[0033] The seedling strengthener mother liquor storage tank 71 and the mildew inhibitor mother liquor storage tank 72 store the corresponding mother liquors respectively. The stirring motor 710 of the anti-sedimentation component inside the tank drives the stirrer 711 to run in advance to prevent the components in the mother liquor from settling. When the equipment starts supplying the agents, metering pump 1 75 and metering pump 2 76 draw mother liquor from the two storage tanks respectively and deliver it to the mixing chamber 77 according to the preset ratio. At the same time, water pump 78 adds an appropriate amount of clean water to the mixing chamber 77. The concentration sensor and flow meter in the mixing chamber 77 monitor the state of the mixed liquid in real time to ensure that the mother liquor and clean water are fully mixed according to the set ratio. After the mixing is completed, the booster pump 79 delivers the mixed liquid through the supply pipe 10 to the atomizing nozzle assembly 9 installed on the robotic arm 8. At this time, the conveying mechanism is steadily conveying the wet blank to the spraying area. The robotic arm 8 drives the atomizing nozzle assembly 9 to adjust to the appropriate position, atomizes the mixed liquid and sprays it evenly on the wet blank, forming a complete agent supply and spraying process.

[0034] The liquid supply mechanism 7 ensures precise and stable pesticide mixing. Independent liquid supply from dual storage tanks and precise volume control via a metering pump, combined with real-time monitoring by sensors within the mixing chamber 77, effectively avoids errors from manual mixing, guaranteeing consistent concentration in each batch of the mixed solution. This solves the problem of concentration fluctuations affecting seedling growth and mold prevention in traditional mixing methods. Furthermore, the mother liquor remains stable. The agitator 711 of the anti-sedimentation component is linked with the metering pump to stir the mother liquor before supply, preventing uneven concentration caused by component sedimentation and further improving the overall uniformity of the mixed solution. The system exhibits strong synergy; the liquid supply mechanism 7 works in conjunction with the atomizing nozzle assembly 9, the robotic arm 8, and the conveying mechanism. The rhythm of the mixed solution delivery is precisely matched with the transport of wet seedlings and the nozzle movements, ensuring timely supply of pesticides when the wet seedlings enter the designated area, avoiding waste or delayed supply. It has high adaptability and practicality, and the overall structure is compact. The proportioning parameters can be adjusted according to the specifications of wet blanks and operational needs. The components are highly automated, reducing manual intervention and operational intensity. Meanwhile, corrosion-resistant storage tanks and other components extend the service life of the equipment, making it suitable for large-scale and continuous seedling production scenarios.

[0035] The conveying mechanism is also equipped with a guiding mechanism, which includes a suspended guiding plate 12. The guiding plate 12 is mounted on the conveyor frame 1 via a guiding bracket 11. A manual knob 13 is rotatably connected above the guiding plate 12, passing through the guiding bracket 11, and is used to adjust the distance between the guiding plate 12 and the silicone conveyor belt 4. The guiding mechanism has strong adaptability; the distance can be adjusted by the manual knob 13 to match wet blanks of different thicknesses. It also provides good blank protection; the suspended design avoids hard contact and protects the fiber structure of the wet blank from damage.

[0036] When the material guiding mechanism is working, the guide plate 12 is suspended above the silicone conveyor belt 4 of the conveyor frame 1 via the guide bracket 11. By rotating the manual knob 13 above the guide plate 12, the distance between the guide plate 12 and the conveyor belt 4 can be flexibly adjusted. During the transmission of the wet blank with the silicone conveyor belt 4, the suspended guide plate 12 forms a limiting guide for the wet blank from above, preventing the wet blank from shifting, tilting or stacking, and ensuring that the wet blank is smoothly transported to the subsequent process.
