Description

Technical Field

[0001] This invention relates to the field of perilla cultivation technology, and in particular to a perilla cultivation spraying device and its usage method. Background Technology

[0002] As a distinctive crop with medicinal, edible, and economic value, the spraying of pesticides during large-scale cultivation of perilla directly affects its growth, pest and disease control effectiveness, and final product quality.

[0003] Existing spraying equipment for perilla or similar dwarf crops has achieved a certain degree of mechanization and automation. For example, an agricultural spraying device with publication number CN118975544A, through the cooperation of an adjustable bracket and spraying pipeline, can achieve adaptive adjustment of spraying height and spraying range, which improves the flexibility and versatility of spraying operations to a certain extent. A mobile perilla planting spraying device with publication number CN219803151U adopts a liftable spray bar and a mobile frame, which can adapt to the changes in plant height of perilla at different growth stages, reduce the intensity of manual labor, and improve the efficiency of field operations.

[0004] In large-scale perilla cultivation, effective spraying of the lower leaves is crucial, a key step in ensuring healthy growth and improving overall yield and quality. The lower leaves are vital for nutrient synthesis and transport, and their growth directly determines the overall vigor of the plant. Furthermore, many common perilla pests and diseases thrive in the lower leaves; insufficient spraying can lead to rapid spread of these pests and diseases throughout the plant, impacting marketability. Additionally, the absorption of foliar fertilizer by the lower leaves directly affects the plant's resistance and uniformity of growth. Insufficient spraying can result in uneven growth, reducing overall cultivation efficiency. Therefore, effective spraying of the lower leaves is a core requirement for large-scale, refined perilla cultivation.

[0005] However, the existing technologies mentioned above still have significant technical shortcomings when applied to perilla cultivation, making it difficult to meet the core requirements. Because perilla plants have numerous branches and dense, overlapping leaves, they easily form a dense canopy of upper foliage that obstructs the flow. The aforementioned equipment uses a conventional top-down spraying method with a single spray path, making it difficult for the pesticide solution to penetrate the area covered by the upper leaves and effectively reach the lower parts of the plant and the lower leaves. This generally results in insufficient spraying of the upper leaves and severe underspraying of the lower leaves. This phenomenon of overspraying the upper layers and underspraying the lower layers not only affects the overall pest control and fertilization effect but also easily leads to pesticide waste and uneven pesticide residues, making it difficult to meet the needs of large-scale, precision perilla cultivation. Summary of the Invention

[0006] This invention provides a perilla planting spraying device and its usage method, which can solve the problems in the prior art that make it difficult to spray the middle and lower leaves of perilla, and that the upper layer is easily over-sprayed while the lower layer is under-sprayed.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a perilla planting spraying device, including a mounting frame assembly, and further comprising: A movable base that can move horizontally on the mounting bracket assembly; A spray frame is vertically rotatably connected to a movable base via a rotating shaft. Multiple sets of spray head assemblies are evenly installed on the spray frame along the height direction. The spray head assemblies are connected to an external liquid supply device via pipelines. The oscillating drive, mounted on the movable base, includes a motor and a transmission structure, and is used to drive the spray frame to oscillate back and forth around the rotating shaft, so that the spray head assembly sprays the perilla plant from the side in an oscillating manner to cover the upper, middle and lower leaves of the plant.

[0008] Preferably, the nozzle assembly includes an upward-tilting nozzle and a downward-tilting nozzle; the upward-tilting nozzle is inclined upwards, and the downward-tilting nozzle is inclined downwards, and the two are arranged in pairs at the same height.

[0009] Preferably, the transmission structure is an L-shaped swing arm, and the spray frame is provided with a constraint hole. One end of the L-shaped swing arm is connected to the output shaft of the motor, and the other end extends into the constraint hole so as to drive the spray frame to swing back and forth around the rotating shaft under the drive of the motor.

[0010] Preferably, there are several movable seats, and a locking element for positioning is provided between the movable seat and the mounting bracket assembly.

[0011] Preferably, the mounting bracket assembly is a height-adjustable movable gantry.

[0012] Preferably, the mounting bracket assembly includes a movable base, a movable frame, and a height adjustment assembly; The movable frame is inserted into the movable base frame, and the movable seat is mounted on the movable frame; The height adjustment component is used to adjust and lock the extension length of the movable frame.

[0013] Preferably, the height adjustment component includes an adjustment shaft, a driven shaft, and a transmission assembly; The control shaft is rotatably connected to the movable base frame; The driven shaft is rotatably connected within the movable base frame and threadedly connected to the movable frame. The transmission assembly is located between the control shaft and the driven shaft to enable them to rotate synchronously.

[0014] This invention also provides a method for using a perilla planting spraying device, comprising the following steps: Move the equipment to the perilla planting area to be sprayed, and adjust the position of the equipment so that the spray rack is to the side of the perilla plants to be sprayed. Connect the pipeline to the external liquid supply device, and the nozzle assembly sprays the perilla from the side. The oscillating drive unit is activated to make the spray frame oscillate back and forth, while the equipment moves along the planting row. Multiple sets of nozzles at different heights continuously spray the perilla from the side during the oscillation, so that the upper, middle and lower leaves can be sprayed with liquid at the same time.

[0015] Preferably, the following steps are performed before the device startup step: Adjust the height of the mounting bracket assembly so that multiple sets of sprinkler heads on the sprinkler rack cover the entire height range of the perilla plant; The positions of several movable seats are adjusted so that the spray racks on the corresponding movable seats are positioned between two rows of perilla leaves, and then locked in place by locking components.

[0016] Compared to existing technologies, this invention features a horizontally movable base on the mounting frame assembly. A vertical spray frame is rotatably connected to the movable base via a rotating shaft, and the spray frame is driven by a swing drive to reciprocate around the shaft. Combined with multiple sets of nozzles evenly arranged along the height of the spray frame, this allows for continuous oscillating spraying from the side of the plant. During the oscillation, the spray coverage dynamically expands with the swing of the spray frame, and the spray angle continuously changes. The pesticide solution can effectively penetrate the dense upper foliage of the perilla plant, evenly reaching the upper, middle, and lower layers of the plant. This fundamentally improves the problems of overspraying the upper layers and underspraying the lower layers caused by traditional top-down spraying methods, significantly enhancing spray uniformity and pesticide utilization. Furthermore, the overall structure is simple, the operation is stable and reliable, and it can adapt to spraying operations at different growth stages of perilla, meeting the high-efficiency operational needs of large-scale, precision planting.

Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1 to 3 As shown, the present invention provides a perilla planting spraying device, including a mounting frame assembly, and further including: a movable base 3, a spray frame 4 and a swing drive component 8.

[0021] The movable seat 3 is horizontally movable on the mounting bracket assembly.

[0022] The spray frame 4 is vertically rotatably connected to the movable base 3 via a rotating shaft 802. Multiple sets of spray head assemblies 5 are evenly installed on the spray frame 4 along the height direction. The spray head assemblies 5 are connected to an external liquid supply device via pipelines 6.

[0023] The swing drive 8 is mounted on the movable seat 3 and includes a motor 801 and a transmission structure. It is used to drive the spray frame 4 to swing back and forth around the rotating shaft 802, so that the nozzle assembly 5 sprays the perilla plant from the side in a swinging manner to cover the upper, middle and lower leaves of the plant.

[0024] Specifically, the mounting frame assembly serves as the overall load-bearing foundation of the equipment, providing an installation carrier and horizontal movement guide for the mobile seat 3. Lightweight, high-strength aluminum alloy profiles or steel square tubes are selected to ensure the strength of field operations and ease of movement. It should be noted that the overall rigidity should be sufficient, with no obvious shaking or deformation during operation, and be able to stably adapt to the working environment between perilla planting beds.

[0025] The movable seat 3 is used to support the sprinkler frame 4 and the swing drive component 8, so as to realize the overall horizontal position adjustment of the sprinkler frame 4. The material is made of engineering plastic or lightweight metal to ensure wear resistance and structural stability. When set, it forms a sliding fit with the mounting frame assembly, and the movement is smooth and without jamming. It can be quickly adjusted to match different perilla planting row spacings.

[0026] The rotating shaft 802 serves as the rotational support center of the spray frame 4, providing a fixed rotation fulcrum for the reciprocating swing of the spray frame 4. It is made of wear-resistant stainless steel or high-hardness metal shaft to ensure long-term swing without wear or jamming. It is vertically installed on the movable seat 3 and fixedly connected to the spray frame 4 to ensure the coaxiality of the swing and the stability of the operation.

[0027] The sprinkler frame 4 is used to install the sprinkler assembly 5 in layers along the height of the plant to achieve full coverage of the perilla plant. Lightweight round or square tubes are selected to reduce the moment of inertia and reduce the driving load. The vertical arrangement matches the height of the perilla plant during normal growth. The sprinkler assembly 5 is evenly distributed along the height so that the upper, middle and lower leaves can receive the liquid.

[0028] The nozzle assembly 5 is used to atomize the pesticide solution and spray it laterally onto the plant. It is made of pesticide-resistant plastic or stainless steel to avoid damage from pesticide corrosion. It should ensure uniform atomization and appropriate spray angle, and be continuously arranged along the height of the spray frame 4 to ensure that there are no gaps or excessive overlap in the spraying range.

[0029] Pipeline 6 is used to connect the nozzle assembly 5 with the external liquid supply device to achieve stable liquid delivery. The material is pressure-resistant, corrosion-resistant, and anti-aging agricultural hose or rigid pipe. The arrangement is neat and does not interfere with the swing path of the spray frame 4. The liquid supply is smooth without leakage or blockage.

[0030] The oscillating drive component 8 provides power to the spray frame 4, driving it to reciprocate around the rotating shaft 802. The motor 801 is a low-speed, high-torque DC geared motor, suitable for continuous field operations. Specific models include 5840-31ZY and 63ZYT-RV025-24-100. It is essential to ensure stable power output and a suitable oscillation angle so that the nozzle assembly 5 expands its coverage area during oscillation, enhancing the pesticide's ability to penetrate the leaf canopy.

[0031] This invention also provides a method for using a perilla planting spraying device, comprising the following steps: Mobile equipment: Move the equipment to the perilla planting area to be sprayed, and adjust the position of the equipment so that the spray rack 4 is on the side of the perilla plants to be sprayed.

[0032] Height adjustment: Adjust the height of the mounting bracket assembly so that the multiple sets of nozzle assemblies 5 on the sprinkler rack 4 can cover the entire height range of the perilla plant.

[0033] Width adjustment: Adjust the position of several movable seats 3 so that the spray rack 4 on the corresponding movable seat 3 is between two rows of perilla leaves, and lock it by locking piece 9.

[0034] Equipment startup: Connect pipeline 6 to the external liquid supply device, and spray nozzle assembly 5 sprays perilla from the side.

[0035] Continuous operation: Start the swing drive 8 to drive the spray frame 4 to swing back and forth, and at the same time move the equipment along the planting row. Multiple sets of nozzles 5 at different heights continuously spray the perilla from the side during the swing, so that the upper, middle and lower leaves can be sprayed with liquid at the same time.

[0036] like Figures 2 to 4 As shown, in order to further solve the problem of the lower blades not being able to receive liquid and the spraying being uneven due to the upper blades blocking the lower blades, preferably, the nozzle assembly 5 includes an upward tilting nozzle 501 and a downward tilting nozzle 502; the upward tilting nozzle 501 is tilted upward and the downward tilting nozzle 502 is tilted downward, and the two are arranged in pairs at the same height.

[0037] Specifically, the underside of perilla leaves has denser stomata, resulting in higher nutrient absorption efficiency. Furthermore, aphids, spider mites, and many diseases originate on the underside of leaves. Therefore, effective spraying of the underside of the leaves is crucial for ensuring healthy growth and improving pest control. By setting up an upward-tilting nozzle 501 and a downward-tilting nozzle 502 at the same height, the downward-tilting nozzle 502 can spray the front of the leaves, while the upward-tilting nozzle 501 can penetrate the gaps in the leaf canopy to directly and precisely spray the underside of the leaves. This ensures that the pesticide adheres evenly to both the front and back of the leaves, fundamentally overcoming the limitation of traditional equipment that can only spray the leaf surface and not the underside, significantly improving pest control effectiveness and pesticide utilization. During setup, the upward-tilting nozzle 501 and the downward-tilting nozzle 502 are fixed in pairs at the same height on the spray frame 4, maintaining a stable spray direction. It should be noted that the tilt angle of the upward-tilting nozzle 501 should be such that it can smoothly pass through the gaps in the leaves and reach the underside of the leaves, avoiding an angle that is too large causing pesticide drift or too small failing to effectively cover the underside of the leaves.

[0038] like Figure 7 As shown, in order to achieve stable and low-stuttering reciprocating oscillation of the spray frame 4 and improve the reliability of the oscillating spray, preferably, the transmission structure is an L-shaped swing rod 803. The spray frame 4 is provided with a constraint hole 401. One end of the L-shaped swing rod 803 is connected to the output shaft of the motor 801, and the other end extends into the constraint hole 401, so as to drive the spray frame 4 to reciprocate around the rotating shaft 802 under the drive of the motor 801.

[0039] Specifically, the transmission method using a rotating shaft 802 in conjunction with an L-shaped swing arm 803 and a constraint hole 401 smoothly converts the rotational motion of the motor 801 into the reciprocating oscillation of the spray frame 4. This precise motion transmission with minimal wobbling maintains a stable spray trajectory, ensuring even hydration of all leaf layers and effectively improving upon the shortcomings of traditional structures, such as jamming and unstable oscillation. During setup, one end of the L-shaped swing arm 803 is fixed to the output shaft of the motor 801, while the other end extends movably into the constraint hole 401. It is important to note that the length of the constraint hole 401 matches the stroke of the L-shaped swing arm 803 to ensure smooth, interference-free oscillation.

[0040] In addition to the L-shaped swing arm 803, the transmission structure can also adopt conventional reciprocating transmission structures such as crank connecting rod, gear rack, incomplete gear or eccentric wheel, all of which can drive the spray frame 4 to swing back and forth stably around the rotating shaft 802 to meet the swing spraying requirements.

[0041] like Figures 1 to 2 As shown, in order to achieve flexible arrangement and positioning of the multi-position sprinkler frame 4 and adapt to different planting row spacings, preferably, there are several movable seats 3, and a locking element 9 for positioning is provided between the movable seat 3 and the mounting frame assembly.

[0042] Specifically, multiple movable seats 3 can be independently adjusted in horizontal position, allowing for flexible changes in the spacing and number of sprinkler frames 4 based on the width of the perilla planting area and the spacing between rows. This ensures the spraying range perfectly matches the field layout, preventing missed areas at the edges or overlapping spraying in the middle, further improving spray adaptability and operational efficiency. During setup, the locking element 9 is installed between the movable seat 3 and the mounting frame assembly, enabling quick positioning after sliding. It should be noted that the locking force is moderate, ensuring no displacement during operation while facilitating quick adjustments by the operator.

[0043] The locking component 9 can be a spring plunger, bolt clamping component, quick release handle, friction plate or cylindrical pin, etc. It fixes the movable seat 3 on the mounting frame assembly by clamping or plugging positioning, ensuring that the movable seat 3 remains stable in position during spraying operations and meeting the usage requirements of different field adjustment speeds and locking strengths.

[0044] like Figures 1 to 2 As shown, in order to improve the overall mobility and site adaptability of the equipment and meet the purpose of large-scale field operations, preferably, the mounting frame assembly is a height-adjustable mobile gantry frame.

[0045] Specifically, the equipment adopts a height-adjustable mobile gantry structure, allowing it to move freely across the field and operate continuously across planting rows. This eliminates the need for frequent manual handling, significantly reducing labor intensity. It is also adaptable to various perilla planting scenarios, including greenhouses and open fields, making it more widely applicable. The gantry is equipped with wheels at the bottom to ensure smooth straight-line movement and flexible turning. It is important to note that the overall center of gravity is centered to prevent tilting during operation.

[0046] like Figures 1 to 2 and Figure 6 As shown, in order to achieve adjustable spray height and adapt to the changes in plant height at different growth stages of perilla, preferably, the mounting frame assembly includes a movable base frame 1, a movable frame 2, and a height adjustment component 7; the movable frame 2 is inserted into the movable base frame 1, and the movable seat 3 is set on the movable frame 2; the height adjustment component 7 is used to adjust and lock the extension length of the movable frame 2.

[0047] Specifically, through the coordinated lifting and lowering of the movable base frame 1 and the mobile frame 2, the working height of the sprinkler frame 4 can be flexibly adjusted according to the different heights of the perilla seedling stage, branching stage, and harvesting stage, ensuring that the sprinkler assembly 5 is always in the optimal spraying position, guaranteeing full plant coverage at different growth stages, and completely solving the problem of poor adaptability of fixed-height equipment. During setup, the mobile frame 2 and the movable base frame 1 are connected with a gap fit to ensure smooth lifting and lowering without jamming. It should be noted that the lifting stroke covers the entire plant height range of the perilla's growth cycle.

[0048] The height adjustment component 7 can be driven by the control shaft 701, the driven shaft 702 and the bevel gear set 703 to drive the movable frame 2 to achieve stable lifting and lowering on the movable base frame 1. Alternatively, a worm gear, electric push rod, gear rod or handwheel screw structure can be used to achieve the same height adjustment effect to adapt to the plant height changes of perilla throughout the entire growth period and ensure that both the upper and lower leaves can effectively receive sap.

[0049] like Figure 6 As shown, in order to achieve the goals of convenient height adjustment operation, stable transmission, and reliable positioning, preferably, the height adjustment component 7 includes an adjustment shaft 701, a driven shaft 702, and a transmission assembly; the adjustment shaft 701 is rotatably connected to the movable base frame 1; the driven shaft 702 is rotatably connected inside the movable base frame 1 and threadedly connected to the movable frame 2; the transmission assembly is disposed between the adjustment shaft 701 and the driven shaft 702 to enable them to rotate synchronously.

[0050] Specifically, the adjusting shaft 701, driven shaft 702, and transmission assembly work together to easily adjust the height of the movable frame 2 manually or electrically. The transmission is smooth, with good self-locking, and the adjusted frame is not easily loosened, maintaining the set height for a long time, thus improving the ease of use and operational stability of the equipment. The adjusting shaft 701 and driven shaft 702 rotate synchronously through the transmission assembly, and the driven shaft 702 and the movable frame 2 are threaded together. It should be noted that the transmission components are well lubricated, and the threaded fit has appropriate precision to avoid difficult adjustments or loosening.

[0051] The transmission assembly uses a bevel gear set 703 to achieve steering transmission. One set of bevel gears is fixed to the control shaft 701, and the other set of bevel gears is fixed to the driven shaft 702. The two sets of bevel gears mesh with each other, converting the horizontal rotation of the control shaft 701 into the vertical rotation of the driven shaft 702, thereby driving the driven shaft 702 to drive the movable frame 2 to rise and fall smoothly. The structure is compact, the transmission is reliable, and it has good self-locking properties.

[0052] In addition to the bevel gear set 703, the transmission assembly can also adopt conventional transmission structures such as worm gear transmission, spur gear transmission, bevel gear transmission, synchronous belt transmission, and chain transmission. All of these can achieve stable synchronous transmission between the control shaft 701 and the driven shaft 702, and meet the steering and power transmission requirements of the height adjustment assembly 7.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
