Description

Technical Field

[0001] This utility model relates to the field of strawberry cultivation technology, specifically to a spraying device for elevated strawberry cultivation. Background Technology

[0002] Currently, strawberry cultivation is gradually shifting from traditional ground planting to elevated cultivation. Elevated strawberry cultivation facilitates agricultural operations, reduces soil-borne diseases, and improves fruit quality, leading to its widespread adoption in the field of facility agriculture. Compared to traditional ground planting, elevated strawberry cultivation racks are typically 0.8-1.5 meters high, with strawberry plants arranged in a three-dimensional, tiered manner on the racks.

[0003] In elevated strawberry cultivation, the commonly used spraying method relies on operators using handheld sprayers to spray row by row. While this allows for some control over the spraying area, it has significant drawbacks. Given the three-dimensional, layered layout of elevated strawberry vines, operators must frequently move between narrow rows, resulting in high labor intensity and low efficiency, making it difficult to meet the pest control needs of large-scale elevated strawberry cultivation bases. Especially for strawberry plants in the middle and lower layers of the elevated cultivation racks, effective pesticide application is often impossible due to limited viewing angle and arm movement, leading to incomplete pest and disease control and consequently affecting strawberry growth. Summary of the Invention

[0004] The purpose of this invention is to provide a spraying device for the process of elevated strawberry cultivation, so as to improve work efficiency and enhance the spraying effect.

[0005] To achieve the above objectives, this utility model proposes a spraying device for elevated strawberry cultivation, comprising a storage tank for containing pesticide solution, and a power assembly for pumping the pesticide solution from the storage tank into a delivery pipeline, and further comprising: A handheld applicator for connecting to a delivery pipeline, the handheld applicator comprising a flexible tube, a handheld part, and a diverter connected in sequence, the input end of the flexible tube being connected to the delivery pipeline; The diversion component includes a central tube and branch units distributed on both sides of the central tube. Each branch unit is provided with multiple branch pipes, which are arranged in a multi-layer structure along the axial direction of the central tube. An atomizing nozzle is installed at the outlet of each branch pipe. The handheld application component is configured to use the pressure generated by the power component to guide the liquid medicine to each branch pipe in the two side branch units through the central pipe. The multi-layered branch pipes correspond to the strawberry plants distributed layer by layer on the planting rack, thus forming a layered application of medicine to the strawberry plants.

[0006] The handheld spraying unit's diversion component can cover multiple layers of plants at once, significantly shortening the operation time compared to the traditional row-by-row, layer-by-layer spraying method, making it particularly suitable for the high-efficiency pest control needs of large-scale elevated strawberry planting bases.

[0007] Preferably, the number of branch pipes in the branch unit is 2-5 layers, and the spacing of each layer of branch pipes is adapted to the height of the elevated strawberry planting rack.

[0008] Preferably, the central tube and the handheld part are detachably connected by a threaded structure, and the input end of the central tube is provided with a filter element for filtering impurities in the medicine solution.

[0009] Preferably, the surface of the handle is provided with anti-slip texture, and a valve for controlling the flow of the liquid medicine is installed on the handle.

[0010] Preferably, the input end of the flexible tube is fixed to the delivery pipeline by a pipe clamp.

[0011] Preferably, a protective cover is provided on the outside of the atomizing nozzle. The protective cover is conical, with the large-diameter end of the protective cover facing the spray direction of the atomizing nozzle, and the small-diameter end of the protective cover being fixedly connected to the outer peripheral wall of the outlet of the branch pipe.

[0012] Preferably, the medicine storage box and power unit are fixedly mounted on a backpack frame, which includes a back panel that conforms to the back of the human body, shoulder straps and waist belt.

[0013] Preferably, the power unit is a gasoline pump, which is equipped with a throttle adjustment knob for controlling the output pressure of the medicine.

[0014] Compared with existing technologies, the spraying device for elevated strawberry cultivation provided by this utility model has the following substantial features and advancements: This spraying device for elevated strawberry cultivation utilizes a multi-layered branch pipe design in the handheld spraying component, which significantly reduces labor intensity and precisely matches the three-dimensional layered layout of elevated strawberries. It reduces the need for operators to move repeatedly between narrow planting rows. With the aid of powered liquid supply and a one-time double-row multi-layered coverage method, spraying time is greatly shortened, and operational efficiency is improved to meet the needs of large-scale cultivation. The multi-layered branch pipes correspond to the plant layers, and combined with the atomizing nozzles, it solves the blind spots of spraying the middle and lower layers of plants in traditional handheld sprayers, ensuring uniform and thorough spraying, reducing the impact of pests and diseases, and helping to improve strawberry quality through efficient and precise spraying while reducing labor and pesticide costs.

[0022] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Strawberries, belonging to the Rosaceae family, are perennial herbaceous plants. Rich in nutrients and with a sweet and sour taste, they are small berries with high economic value, classified as high-end fruits, and are loved by consumers both domestically and internationally, earning them the reputation of "Queen of Fruits." Due to increasing market demand, coupled with their ease of propagation, management, and short growth cycle, as well as their high edible and ornamental value, strawberries have not only experienced rapid development in domestic greenhouse cultivation and fruit picking, but have also become an important economic crop for increasing farmers' income and wealth.

[0024] Currently, strawberry cultivation is gradually shifting from traditional ground planting to elevated cultivation. Elevated strawberry cultivation facilitates agricultural operations, reduces soil-borne diseases, and improves fruit quality, leading to its widespread adoption in the field of facility agriculture. Compared to traditional ground planting, elevated strawberry cultivation racks are typically 0.8-1.5 meters high, with strawberry plants arranged in a three-dimensional, tiered manner on the racks.

[0025] In elevated strawberry cultivation, the commonly used spraying method relies on operators using handheld sprayers to work row by row. While this can control the spraying area to some extent, it has significant drawbacks. Given the three-dimensional, layered layout of elevated strawberry cultivation, operators need to move frequently between narrow rows, resulting in high labor intensity, low efficiency, and an inability to meet the pest control needs of large-scale elevated strawberry cultivation bases. Furthermore, long-term operation poses serious health risks to operators and incurs high labor costs.

[0026] Furthermore, strawberry plants located in the middle and lower layers of elevated cultivation racks often cannot be effectively sprayed due to limitations in the operator's viewing angle and arm range of motion, resulting in incomplete pest and disease control and consequently affecting strawberry growth. Therefore, there is an urgent need to develop a specialized spraying device that is highly compatible with elevated cultivation models and is efficient, safe, and flexible, to fill the gaps in existing technology and promote the high-quality development of the strawberry industry.

[0027] Therefore, the three-dimensional, layered layout of elevated strawberry cultivation requires operators to move frequently between narrow planting rows, resulting in high labor intensity and low efficiency, making it difficult to meet the pest and disease control needs of large-scale elevated strawberry cultivation bases. Especially for strawberry plants located in the middle and lower layers of the elevated planting racks, effective pesticide application is often impossible due to limitations in the operator's viewing angle and arm range of motion, leading to incomplete pest and disease control and consequently affecting strawberry growth. This utility model proposes a spraying device for elevated strawberry cultivation, aiming to improve operational efficiency and enhance spraying effectiveness.

[0028] like Figure 1 and Figure 2 As shown, a spraying device for elevated strawberry cultivation includes a storage tank 1 for holding pesticide solution and a power assembly 2 for pumping the pesticide solution from the storage tank 1 into a delivery pipeline. It also includes: Handheld application assembly 3 for connecting to the delivery pipeline, such as Figure 2 As shown, the handheld application assembly 3 includes a flexible tube 31, a handheld part 32, and a diversion component 33 connected in sequence. The input end of the flexible tube 31 is connected to the delivery pipeline.

[0029] The diversion component 33 includes a central pipe 331 and branch units distributed on both sides of the central pipe 331, such as... Figure 3 As shown, the branch unit is provided with multiple branch pipes 332, which are arranged in a multi-layer structure along the axial direction of the central pipe 331. Atomizing nozzles 35 are installed at the outlet of the branch pipes 332.

[0030] The handheld spraying component 3 is configured to use the pressure generated by the power component 2 to guide the liquid medicine through the central tube 331 to each branch tube 332 in the two side branch units. The multi-layered branch tubes 332 correspond to the strawberry plants distributed layer by layer on the planting rack, thus forming a layered spraying of the strawberry plants.

[0031] The diversion component 33 is designed as a multi-layer structure with multiple branch pipes 332 along the central pipe 331. The arrangement spacing of the multi-layer branch pipes 332 can match the layering of plants within the height of the elevated planting rack from 0.8 to 1.5 meters, so as to achieve precise coverage of one layer of branch pipes 332 corresponding to one layer of plants. This avoids the omission of middle and lower layer plants due to the limited field of view and arm movement range of traditional handheld sprayers.

[0032] The atomizing nozzle 35 ensures uniform application of pesticides by converting the pesticide solution into fine droplets. This guarantees that the pesticide adheres evenly to both sides of the leaves and the surface of the fruit, while avoiding the problems of localized pesticide accumulation or missed areas found in traditional sprayers. Simultaneously, the controlled diffusion range of the atomized droplets reduces pesticide waste and allows the pesticide to penetrate deep into the gaps between plants, further reducing the risk of strawberry growth being negatively impacted by incomplete application.

[0033] The flexible tube 31 is advantageous for adapting to narrow working spaces. When operators move within the narrow row spacing of the elevated planting rack, the flexible tube 31 can bend flexibly, avoiding the problems of rigid pipes getting stuck or colliding with plants. This protects the strawberry plants from damage and improves operational flexibility. For example, the input end of the flexible tube 31 is fixed to the delivery pipe with a pipe clamp.

[0034] Based on the specific structure of the elevated strawberry planting rack, in the branch unit of the spraying device for elevated strawberry planting proposed in this embodiment of the utility model, the number of layers of branch pipe 332 is 2-5, and the spacing of each layer of branch pipe 332 is adapted to the layer height of the elevated strawberry planting rack.

[0035] Therefore, the number of layers in the planting rack can be flexibly adjusted according to the actual situation, while the spacing between layers is precisely aligned with the height of the planting rack. This allows the device to adapt to different scales and specifications of elevated planting scenarios, such as family farms, medium-sized cooperatives, and large-scale planting bases, significantly improving compatibility. For example, Figure 4 As shown, the number of layers of branch pipe 332 in the branch unit is 2, which is used to adapt to the usage scenarios of small and medium-sized planting bases.

[0036] like Figure 2 As shown, the medicine storage box 1 and the power unit 2 are fixedly mounted on the backpack support 4. The backpack support 4 enables the equipment to move freely between the operator and the plant, allowing the operator to move freely through the curved planting rows and gaps between the columns without worrying about the equipment getting stuck or colliding. Simultaneously, it eliminates the need to reserve space for the cart to turn around at both ends of the planting rows, making full use of every inch of the greenhouse planting area, especially suitable for planting bases with high greenhouse utilization and compact aisle designs. For example, the backpack support 4 includes a back panel that conforms to the human back, shoulder straps, and a waist belt.

[0037] The spraying device for elevated strawberry cultivation proposed in this embodiment can also integrate the pesticide storage box 1 and the power component 2 into the trolley structure.

[0038] For example, power component 2 is a gasoline pump. The gasoline pump is equipped with a throttle adjustment knob for controlling the output pressure of the pesticide solution. Thus, the gasoline pump is driven by gasoline fuel and can operate continuously for 4-6 hours after a full tank of fuel, which fully meets the needs of large-scale bases for multiple daily treatments without the need for frequent interruptions to replenish energy. It is especially suitable for planting environments without a stable power supply.

[0039] The throttle adjustment knob allows for active adjustment of the pesticide solution pressure to meet the control requirements of different pests and diseases. For example, controlling leaf aphids requires fine droplets to ensure even adhesion, while controlling root rot at the stem base requires slightly higher pressure to allow the solution to penetrate to the substrate surface. By quickly adjusting the pressure through the throttle adjustment knob, incomplete control or excessive pesticide residue caused by improper pressure can be avoided, thus improving pest and disease control efficiency, reducing pesticide waste, and lowering planting costs.

[0040] like Figure 4 As shown, the central tube 331 and the handheld part 32 are detachably connected by a threaded structure, which facilitates the assembly and connection of the central tube 331 and the handheld part 32. The input end of the central tube 331 is provided with a filter element for filtering impurities in the medicine solution.

[0041] Elevated strawberry greenhouses require high humidity, and pesticide solution can easily splash onto the surface of the handle 32 during application, reducing friction between the hand and the handle 32. Therefore, the surface of the handle 32 is provided with anti-slip textures. These textures increase the grip contact area, allowing for a firm grip even when the hand is wet with pesticide solution or sweat, preventing the handheld pesticide application component 3 from slipping and falling off.

[0042] The handheld part 32 is equipped with a valve 34 for controlling the flow of the pesticide solution. The valve 34 can be directly operated by the thumb or forefinger. When the operator moves, adjusts their posture, or avoids ripe fruit, the valve 34 can be closed immediately to cut off the pesticide flow. It can then be quickly reopened during operation, greatly reducing unnecessary pesticide consumption.

[0043] In elevated strawberry cultivation, the row spacing is typically 0.7-0.9 meters, with the plants arranged in a three-dimensional, tiered distribution. Due to greenhouse ventilation or natural airflow, pesticide solution from upper spray nozzles can drift to adjacent rows, while solution from lower spray nozzles can splash onto the substrate surface. Therefore, as... Figure 5 and Figure 6 As shown, a protective cover 351 is provided on the outside of the atomizing nozzle 35. The protective cover 351 is conical. The large-diameter end of the protective cover 351 is oriented towards the spray direction of the atomizing nozzle 35, and the small-diameter end of the protective cover 351 is fixedly connected to the outer peripheral wall of the outlet of the branch pipe 332.

[0044] The conical protective shield 351 is used to confine the droplet diffusion range within 30-40cm, ensuring that the atomized pesticide accurately covers the target plants at the corresponding level. For example, the protective shield 351 of the upper nozzle guides the pesticide to concentrate on the upper leaves and fruits, preventing it from drifting to lower plants and causing repeated application. The protective shield 351 of the lower nozzle prevents the pesticide from splashing onto the ground and is wasted, while also reducing cross-contamination of the pesticide between adjacent planting rows. Furthermore, the conical protective cover 351 has a converging and guiding effect on the droplets, allowing the atomized fine droplets to converge towards the center along the inner wall of the cover 351, forming a directional spray of mist rather than random diffusion. This directional mist flow can penetrate the gaps between plant leaves more efficiently, evenly adhering to key areas such as the front and back of leaves and the fruit stem end. Especially effective against pests such as aphids and spider mites hiding on the underside of leaves, the converged droplets increase coverage density, further reducing the risk of incomplete pest and disease control.

[0045] This utility model is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, this utility model may have other implementation methods. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
