Description

Technical Field

[0001] This invention relates to the field of agricultural and forestry plant protection technology, specifically a spraying device for stem borers. Background Technology

[0002] Boring insects, such as longhorn beetles, jewel beetles, and bark beetles, are among the major pests affecting forest trees, fruit trees, and landscape trees. The larvae of these insects bore into the phloem and xylem of trees, creating winding tunnels that obstruct the transport of nutrients and water, weakening the tree and even causing it to die. Because they live in secluded locations, they are difficult to control. Conventional foliar spraying or soil application methods often fail to effectively deliver pesticides to the affected areas, resulting in unsatisfactory control outcomes.

[0003] Currently, chemical control methods for stem-boring pests mainly include: 1) Injection method: The medicine is injected into the trunk through drilling. This method can directly deliver the medicine to the affected area. However, drilling will cause mechanical damage to the tree and has low operation efficiency, making it difficult to apply on a large scale. 2) Trunk wrapping or smearing method: Apply or wrap the pesticide solution to the base of the trunk, relying on the tree's conduction to transport the pesticide upward. This method is greatly affected by tree species, tree age, and environmental factors, and the efficacy is unstable. It also has limited effect on larvae that have already damaged the deep wood. 3) Manually inserting poison sticks or filling ointment: For the discovered insect holes, manually insert poison sticks soaked in medicine or fill them with ointment. This method is highly targeted, but it relies entirely on manual search for insect holes, which is time-consuming and labor-intensive. It is difficult to operate on tall trees or in cases where the insect holes are located high up, and there are also safety risks.

[0004] Some mechanized pesticide application devices have emerged in the current technology. For example, some devices use high pressure to inject pesticide directly into the insect holes, but this usually requires manual holding of the nozzle to aim at the insect holes, demanding a high level of skill and experience from the operator, and prolonged operation can easily lead to fatigue. Other devices attempt to use fixed nozzle arrays to apply pesticides around the tree trunk, but they are difficult to adapt to the different diameters of different trees, the irregular distribution of insect holes, and the unevenness of the trunk surface, resulting in uneven pesticide coverage, missed areas, or wasted pesticide. More importantly, most existing devices have limited or inconvenient height adjustment capabilities, making them ineffective in controlling pests occurring in the canopy layer or higher parts of the tree trunk.

[0005] Therefore, there is a need in this field for a highly automated, efficient pesticide application device that can flexibly adjust the application height and angle, and accurately atomize and spray the pesticide solution to the parts or holes damaged by borers, in order to overcome the shortcomings of existing technologies such as high dependence on manual labor, inconvenient operation, poor adaptability, and unsatisfactory control effects. Summary of the Invention

[0006] The purpose of this invention is to provide a spraying device for trunk borers. By setting up a height-adjustable support column to adjust the overall height, and using a motor to drive a gearbox, crank connecting rod and multi-section hinged swing rod to drive the atomizing nozzle to swing back and forth at multiple angles, a wide range, high efficiency and precise application of pesticides that can adapt to different trunk heights and shapes can be achieved, thereby improving the control effect of trunk borers.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a spraying device for borers, comprising a mounting base. A height-adjustable lifting column is mounted above the mounting base, and a support mounting seat is fixed at the top of the lifting column. A drive motor providing power is mounted on the support mounting seat.

[0008] Furthermore, the front and rear ends of the drive motor are respectively connected to reduction gearboxes to reduce the speed and increase the output torque. Each reduction gearbox has a rotatable turntable on each of its left and right output ends, and a crank connecting rod for converting rotary motion into reciprocating motion is hinged to the outer end face of each turntable.

[0009] Furthermore, each crank connecting rod has a reciprocating swing rod connected to its free end. The other end of the swing rod is equipped with an atomizing nozzle that can spray out liquid medicine, and the back of the atomizing nozzle is connected to an inlet pipe for delivering liquid medicine.

[0010] Furthermore, the support mounting base and the drive motor are connected and fixed by multiple fastening bolts. This connection method ensures that the entire power unit and the support structure remain firm and stable during the operation of the drive motor, without any displacement or loosening.

[0011] Furthermore, the reduction gearbox adopts a fully enclosed shell structure design. This sealed design effectively prevents possible external environmental contaminants such as liquid sprays, dust impurities, or moisture from entering the gearbox, thereby protecting the internal gear transmission mechanism and extending its service life.

[0012] Furthermore, the lifting support adopts a hydraulically driven telescopic structure. Inside the support is a mechanical or hydraulic locking mechanism that activates immediately when the lifting support is adjusted to the desired working height, firmly locking the support in that position. This ensures precise and stable fixation of the support mounting base and its upper structure at different heights.

[0013] Furthermore, the inlet pipe is made of a flexible hose material that has excellent resistance to pesticide chemicals. One end of this flexible hose is connected to the external power system for supplying the pesticide solution, and the other end is connected to the inlet of the atomizing nozzle through a reliable seal to ensure that the pesticide solution does not leak during delivery.

[0014] Furthermore, multiple holes are evenly machined along the circumference of the turntable body. These holes serve as weight-reduction holes. Their function is to minimize the overall mass of the rotating parts while ensuring that the turntable itself has sufficient structural strength and rigidity, thereby reducing its moment of inertia and facilitating the rapid start-stop and energy-saving operation of the motor.

[0015] Furthermore, the swing arm is composed of two or more arm sections connected sequentially via hinge shafts. This multi-section hinged structure allows the swing arm to bend within a certain range, thereby allowing the atomizing nozzles installed at the ends to flexibly adjust their orientation to meet the spraying needs of different parts and angles of the tree trunk.

[0016] Furthermore, a manually operated quick-connect coupling is installed at the interface where the liquid inlet pipe connects to the atomizing nozzle. This coupling allows users to quickly connect and disconnect the pipeline without tools, greatly facilitating equipment assembly, nozzle replacement, or pipeline maintenance.

[0017] This invention provides a spraying device for borers, which has the following beneficial effects: 1. Highly targeted, effectively solving the problem of pesticides not being able to directly reach insect tunnels. This device precisely aligns the atomizing nozzle at the end of the swing rod with the insect holes or tunnels of wood-boring pests. A crank-connecting rod mechanism driven by a motor causes the nozzle to swing back and forth within a certain angle, forming a fan-shaped spray coverage area. Compared with traditional methods relying on natural penetration or large-area spraying, this design significantly improves the penetration and uniform deposition of the pesticide in narrow, tortuous insect tunnels, delivering the pesticide directly to the core area of ​​pest activity. This greatly enhances the control effect on hidden wood-boring pests such as longhorn beetles and wood-boring moths, reducing pesticide waste and contamination of non-target areas.

[0018] 2. The ingenious structural design efficiently converts rotational motion into the required oscillation, and facilitates adjustment of the working angle. The device comprises a drive motor, reduction gearbox, turntable, and crank connecting rod, forming a complete motion transmission system. This system transforms the continuous rotation of the motor into the regular oscillation of the atomizing nozzle, ensuring stable and reliable operation. Furthermore, the multi-section hinged design of the oscillation rod provides multi-degree-of-freedom adjustment capabilities. Operators can flexibly adjust the final orientation of the nozzle according to the actual position and angle of the insect holes on the tree trunk, enabling it to target borer holes at different heights and directions. This significantly enhances the device's adaptability to complex forest environments, ensuring precise application even on uneven bark surfaces.

[0019] 3. Key components possess excellent environmental adaptability and protection capabilities, ensuring long-term stable operation. The device incorporates targeted designs in several vulnerable or critical areas: the reduction gearbox employs a sealed structure, effectively isolating external dust, moisture, and potentially corrosive liquids, protecting the internal gear transmission system; the inlet pipe uses a corrosion-resistant flexible hose, capable of withstanding the erosion of various chemical agents, and its quick-connect couplings facilitate disassembly and maintenance; the lifting support uses a hydraulic telescopic structure with a locking mechanism, ensuring smooth lifting and secure locking at any height, adapting to tree trunks of varying thicknesses. These designs collectively enhance the device's durability and reliability under harsh outdoor conditions such as humidity, dust, and contact with chemical agents.

[0020] 4. Balancing functionality and portability to improve operational efficiency. The entire device is based on a movable mounting base, facilitating relocation within forest areas. The hydraulic lifting support allows for quick adjustment of the nozzle assembly's working height, eliminating the inconvenience and risks of manual climbing or using ladders, thus reducing labor intensity. Weight-reducing holes on the turntable reduce the rotational inertia of rotating components while ensuring strength, contributing to smooth motor start-up and energy savings. The oscillating nozzle design allows for single-positioning to cover a specific fan-shaped area, reducing the number of equipment moves and repositioning operations. These integrated design features enable rapid deployment, flexible adjustment, and efficient operation, making it particularly suitable for large-scale control of borers in orchards, shelterbelts, and other applications requiring large-scale pest control.

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example 1

[0026] A spraying device for borers, particularly suitable for tree species infested by borers such as the ash shrub beetle and the poplar longhorn beetle. The device is designed to be compatible with the small agricultural sprayers commonly owned by farmers. In implementation, the mounting base 1 is first securely fixed to a dedicated support at the rear or side of the sprayer. The mounting base 1 is the foundation of the entire device, and its stability is crucial. Next, the operator adjusts the lifting column 2 manually or via a hydraulic pump, based on the average height of the trees to be sprayed. The lifting column 2 employs a hydraulic telescopic structure with a reliable internal locking mechanism, easily raising the support mounting base 3 and all components above it to a suitable working height, such as two to three meters above the ground, and locking it stably. The support mounting base 3 is a heavy metal plate rigidly fixed to the top of the lifting column 2 with bolts. The drive motor 4 is tightly mounted on the upper surface of the support mounting base 3 with a set of high-strength bolts. This connection method ensures the overall structural stability of the motor during high-frequency start-up and operation, preventing displacement or loosening due to vibration.

[0027] After the drive motor 4 starts, its output shaft transmits power to the reduction gearbox 5 connected at both ends. The reduction gearbox 5 is the core transmission component, featuring a fully sealed design with sealing gaskets at the housing joints. This design effectively prevents pesticide droplets or dust and sand from entering the gear transmission mechanism during operation, thus protecting the gears, extending their service life, and maintaining a stable transmission ratio. A turntable 6 is connected to each end of the output shaft of the reduction gearbox 5. The turntable 6 is disc-shaped, with multiple circular weight-reducing holes evenly distributed along its circumference. These weight-reducing holes significantly reduce the overall inertia of its rotating components while ensuring sufficient structural strength for torque transmission. Reduced inertia means that the drive motor 4 experiences a smaller load, faster response, and lower energy consumption when driving its rotation, and also facilitates smooth operation of the device with a low-power power source.

[0028] A connecting shaft is fixed at an off-center position on the end face of the turntable 6, and one end of the crank connecting rod 7 is sleeved on this connecting shaft. When the turntable 6 is driven to rotate by the reduction gearbox 5, its eccentric shaft drives the crank connecting rod 7 to perform planar motion. The other end of the crank connecting rod 7 is hinged to the starting end of the swing rod 8 via a pin. In this embodiment, the swing rod 8 is composed of two metal rods of equal length connected by a hinge shaft. This multi-section hinged structure allows the atomizing nozzle 9 at the end to flexibly adjust its orientation, rather than being limited to swinging in a single plane. The operator can manually fine-tune the angle between the two rod sections according to the shape of the tree crown, so that the spray direction of the atomizing nozzle 9 can be more accurately aimed at the dense foliage area, improving the targeting and coverage of the spray.

[0029] The atomizing nozzle 9 is fixedly installed at the end of the swing arm 8. A liquid inlet is located at the rear end of the atomizing nozzle 9, and a corrosion-resistant flexible hose 10 is sealed to this inlet via a quick connector. The quick connector design allows for easy separation of the liquid inlet hose 10 from the atomizing nozzle 9 without tools during off-peak hours or when the nozzle needs to be replaced or cleaned, greatly simplifying daily maintenance. The other end of the liquid inlet hose 10 extends and connects to the pressurized output port of the small agricultural machinery sprayer. The entire device utilizes the oscillating principle of a car windshield wiper, converting the rotational motion of the motor into the reciprocating oscillation of the nozzle. This achieves comprehensive and even pesticide coverage of individual trees from trunk to crown within the narrow spacing of the nursery, effectively controlling trunk-boring pests such as the ash leaf beetle. Example 2

[0030] This embodiment describes an operation method for a spraying device targeting borers on tall saplings in a nursery. The target species are large trees such as ash and elm, exceeding four meters in height. In this case, the adjustment function of the lifting support 2 is particularly important. The operator first fixes the mounting base 1 onto a small, low-profile, hand-push mobile chassis. This chassis can support a small spray tank and the spraying device, facilitating flexible movement within narrow 2m x 2m row spacing. The hydraulic mechanism of the lifting support 2 is activated, smoothly raising the support mounting base 3 to a height of approximately four meters. The locking mechanism inside the lifting support 2 employs a double lock of ratchet and hydraulic system, ensuring that the support mounting base 3 and its supporting heavy components, such as the drive motor 4, will not accidentally slide down under the continuous vibration of the spraying operation, thus guaranteeing the safety and stability of the high-altitude operation.

[0031] Once the device is in place, the drive motor 4 is powered on. The high-speed rotation output from the motor is significantly reduced in speed and increased in torque by the reduction gearboxes 5 at both ends. The sealing performance of the reduction gearboxes 5 is tested in this high-humidity, dusty environment. Its sealed design ensures that no external impurities can enter, and the gears mesh smoothly under the protection of lubricating grease, transmitting power to the turntables 6 on both sides. In this embodiment, the turntables 6 are made of aluminum alloy to further reduce weight. The weight-reducing holes on the surface of the turntables not only reduce weight but also facilitate air circulation and reduce wind resistance during rotation. The two turntables 6 rotate synchronously but in opposite directions, thereby driving the corresponding swing rods 8 through their respective crank connecting rods 7.

[0032] In this embodiment, the swing arm 8 is composed of three shorter sections hinged together, forming a structure similar to a "multi-joint robotic arm." This design gives the atomizing nozzle 9 a great degree of freedom of movement. Driven by the crank-connecting rod 7, the base of the swing arm 8 swings back and forth regularly. When this swing is transmitted to the end through multiple hinge points, the trajectory of the atomizing nozzle 9 is not a simple arc, but a complex swing that can cover a larger three-dimensional space. By pre-adjusting the hinge angles between the sections, the sweeping range of the nozzle can be better matched to the conical crown of tall trees, ensuring that the atomizing mist is received from the thicker branches at the bottom to the thinner branches at the top.

[0033] The pesticide solution is supplied through the inlet pipe 10. Due to the increased operating height, the inlet pipe 10 needs to be of sufficient length and flexibility. The corrosion-resistant flexible hose used will not experience excessive stress fatigue when moving with the swing rod 8. The inlet pipe 10 is connected to the atomizing nozzle 9 via a quick connector with a self-locking function to prevent the connector from detaching due to the impact of high-pressure pesticide solution. During actual spraying, the swinging atomizing nozzle 9 atomizes the pesticide solution into fine particles. Under the continuous swing driven by the motor, the pesticide mist is evenly delivered to all parts of the tall tree canopy, solving the problem that traditional fixed nozzles or manual spray guns cannot effectively cover the top of the tree canopy, and achieving whole-tree control of trunk-boring pests on tall seedlings. Example 3

[0034] This embodiment focuses on demonstrating the flexible adaptability of the spraying device when dealing with irregular tree canopies or when lateral spraying is required. The mounting base 1 is installed on the rear suspension of a small four-wheeled agricultural tractor. The tractor's power take-off shaft provides power to the drive motor 4, while its onboard pesticide tank serves as the supply system. The lifting strut 2 is adjusted to a medium height so that the atomizing nozzle 9 is roughly aimed at the central canopy area of ​​the tree. The drive motor 4 is securely connected to the support mounting base 3 with bolts, ensuring that the motor mounting point does not loosen when the tractor travels on uneven nursery ground; this is fundamental to ensuring the accuracy of the transmission mechanism.

[0035] The drive motor 4 drives the reduction gearboxes 5 on both sides. The sealed design of the reduction gearboxes 5 plays a significant role in this dusty field environment, effectively isolating soil particles and protecting the internal precision gears. The turntable 6 rotates at a constant speed under the drive of the gearboxes. The weight-reducing hole design on it reduces rotational resistance, making the entire swing system operate more smoothly and reducing the load on the motor and energy consumption. The crank connecting rod 7 converts the rotation of the turntable 6 into reciprocating pulling force, which is the core power driving the swing arm 8.

[0036] The key to this embodiment lies in the hinged configuration of the swing arm 8. The swing arm 8 consists of two hinged sections, but the hinge shaft is not completely fixed, allowing for angle adjustment with some damping. When it is necessary to focus spraying on the densely growing branches and leaves on one side of the tree, the operator can manually bend the last section of the swing arm 8 (the section where the atomizing nozzle 9 is installed) and fix it to that side. At this time, although the base of the swing arm 8 still swings in its original planar direction under the drive of the crank connecting rod 7, the actual sweeping plane of the atomizing nozzle 9 also deflects due to the angular offset of the last section, thus enabling concentrated spraying on the side of the tree. This adaptive adjustment does not require changes to the main structure of the device and can be achieved through simple manual operation.

[0037] The atomizing nozzle 9 oscillates and sprays pesticides in sync with the angled swing rod 8. The inlet pipe 10, serving as the channel connecting the pesticide source and the nozzle, ensures that the pipe will not be kinked or overstretched even when the angle of the swing rod 8 changes, maintaining a continuous and unobstructed pesticide delivery. The quick-connect fitting at the end of the inlet pipe 10 allows for rapid disconnection from the nozzle before adjusting the angle of the swing rod 8 and quick reconnection after adjustment, simplifying the operation process. This embodiment demonstrates how the device can address asymmetrical spraying needs through simple adjustments, improving pesticide utilization efficiency and control effectiveness. Example 4

[0038] This embodiment describes a spraying operation scenario for low-growing, densely planted seedlings and shrubs in urban greening. In this scenario, the trees are low in height but densely spaced, requiring a device capable of wide lateral coverage. The mounting base 1 is fixed to the front of the bed of a small electric tricycle. The lifting support 2 is adjusted to a low working height, so that the atomizing nozzle 9 is approximately level with the upper-middle part of the seedlings. The supporting mounting base 3 maintains good rigidity at this low height. The drive motor 4 is securely mounted, with its power selected to accommodate continuous operation and drive the dual-sided swing mechanism.

[0039] The drive motor 4 transmits power through the reduction gearbox 5. The airtight design of the reduction gearbox 5 ensures reliable operation even in environments close to the ground where mud and water are more likely to splash up. The turntables 6 on both sides rotate synchronously, and the weight-reducing holes on their surfaces help the device respond quickly during frequent starts and stops (corresponding to intermittent spraying of different trees), reducing lag caused by inertia. The crank-connecting rod 7 converts the rotational motion into linear reciprocating motion, and its length is one of the important parameters determining the swing amplitude of the swing arm 8.

[0040] In this embodiment, to achieve a larger lateral spray coverage area, the swing rod 8 adopts a single-section, relatively long rod design (rather than multi-section hinged joints). Driven by the crank connecting rod 7, the atomizing nozzle 9 at the end of the longer swing rod 8 can swing in an arc with a larger radius. In this way, when the device moves slowly between rows of seedlings, the large left-right swing of the atomizing nozzle 9 can cover a wider lateral range. A single swing can spray multiple adjacent seedlings, or perform a more thorough left-right scanning spray on a single seedling, ensuring that the front and back of the branches and leaves are covered with pesticide.

[0041] The atomizing nozzle 9 swings at high speed at the end of the long swing rod 8, atomizing and spreading the pesticide solution. The inlet pipe 10 needs sufficient length to accommodate the wide range of swing of the long rod, and its flexibility avoids pulling. The quick connector between the inlet pipe 10 and the atomizing nozzle 9 facilitates individual cleaning or replacement of the nozzle after operation. The entire device utilizes the swing principle to achieve wide and uniform pesticide application in low-growing seedling areas, overcoming the shortcomings of large machinery not being able to enter and small mechanical spray guns not providing sufficient coverage. It is particularly suitable for controlling the early stage of trunk-boring pests active on low branches and trunks. Example 5

[0042] This embodiment focuses on the ease of maintenance and durability of the spraying device in practical operation. The connection between the mounting base 1 and the agricultural machinery uses a quick-release clamp design, but it is ultimately tightened with bolts during operation to ensure stability. Even after long-term use, the hydraulic system and locking mechanism of the lifting support 2 can still operate reliably, thanks to daily protection against impurities and dust. The bolted connection between the support mounting base 3 and the drive motor 4 allows for quick disassembly and installation using common tools when the motor needs maintenance, resulting in high maintainability.

[0043] As the power source, the reliability of the drive motor 4 is crucial. The sealed design of the reduction gearbox 5, directly connected to it, is the core guarantee of durability. This design effectively prevents moisture containing chemicals, corrosive gases, and field dust from entering the gearbox, avoiding abnormal wear, rust, and contamination of lubricating grease. Working long-term in harsh orchard and nursery environments, the well-sealed reduction gearbox 5 significantly extends maintenance cycles and service life. The weight-reducing hole design of the turntable 6 also indirectly improves durability, as lighter rotating parts place less impact load on bearings and connectors.

[0044] The multi-section hinged design of the swing arm 8 not only provides flexibility but also facilitates replacement. If a section of the arm is damaged due to an accidental impact, only that section can be replaced instead of the entire swing mechanism, reducing operating costs. The pins at the hinge points are standard parts, making them easy to obtain and replace. The connection point between the crank connecting rod 7 and the swing arm 8 uses a self-lubricating bearing, reducing maintenance requirements.

[0045] The quick-connector at the junction of the inlet pipe 10 and the atomizing nozzle 9 is a prominent feature of the convenience of this embodiment. After each day's work, to prevent pesticide residue from crystallizing and clogging the nozzle, the operator can instantly disconnect the inlet pipe 10 from the atomizing nozzle 9 and immerse the nozzle in clean water for cleaning, without disassembling the complex piping. Similarly, if the atomizing nozzle 9 wears down due to long-term use and needs to be replaced with a new model or a nozzle with a different atomizing cone angle, the quick-connector allows for replacement within seconds, greatly improving the efficiency of work preparation. The entire device is designed with the actual maintenance needs of field use in mind, ensuring its long-term and stable performance in controlling borers.
