Description

Technical Field

[0001] This invention relates to the field of spraying device technology, specifically to a pesticide spraying device for the prevention and control of garden pests and diseases. Background Technology

[0002] In the field of garden maintenance, pest and disease control is a core element in ensuring the healthy growth of trees and maintaining the ecological stability of gardens. Currently, pest and disease control for garden trees mainly relies on two key methods: one is to spray pesticides to kill pests and pathogens such as aphids and spider mites on the surface of leaves and branches; the other is to wrap insect-proof tape around the lower part of the trunk, using the smooth surface of the tape to prevent larvae from climbing to the upper part of the trunk and causing damage.

[0003] Currently used garden spraying devices (such as backpack electric sprayers and trolley-type high-pressure sprayers) can only atomize or spray pesticides under high pressure. They are designed solely for the single need of spraying and cannot simultaneously perform the wrapping of insect-repellent tape. The wrapping of existing insect-repellent tape is mostly done manually, requiring operators to hold the tape roll and gradually wrap it around the tree trunk. This results in high labor intensity and low efficiency, affecting the insect-repellent barrier effect. While some semi-automatic tape-wrapping equipment can assist in wrapping, it cannot integrate spraying functionality and still needs to be used separately from the spraying device, failing to solve the core problem of "secondary work."

[0004] In summary, the current separate operation mode of spraying and wrapping with tape in the prevention and control of garden pests and diseases leads to increased equipment usage costs, increased labor intensity, and low overall prevention and control efficiency, making it difficult to meet the needs of "efficient and integrated" pest and disease control in garden maintenance. Summary of the Invention

[0013] Optionally, the drug delivery tube has a horizontal section and a vertical section, the horizontal section and the vertical section are arranged to cross each other and are interconnected, and each of the horizontal section and the vertical section is provided with a plurality of nozzles.

[0014] Optionally, the movable end of the push rod is provided with an arc-shaped seat, which can support and guide the drug delivery tube so that the push rod drives the drug delivery tube to swing back and forth.

[0027] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-7As shown, this invention illustrates a pesticide spraying device for controlling garden pests and diseases in one embodiment, comprising a mobile frame 1, a spraying assembly 2, and a tape wrapping assembly 3. Specifically, the spraying assembly 2 is mounted on the mobile frame 1 and has several nozzles 21 for spraying pesticides onto plants in the garden. The tape wrapping assembly 3 includes a support plate 31, a winding ring 32, and an installation roller 33. The support plate 31 is mounted on the mobile frame 1. The winding ring 32 is rotatably mounted on the support plate 31 and has an insertion port 3201 for a tree trunk to enter the winding ring 32. The installation roller 33 is rotatably mounted on the winding ring 32 and positioned near the insertion port 3201. The installation roller 33 is used to install insect-repellent tape 300, which is sleeved on the outer periphery of the installation roller 33. The installation roller 33 can rotate with the winding ring 32 so that the insect-repellent tape 300 is wrapped around the tree trunk.

[0029] Specifically, the mobile frame 1 automatically moves, is pushed, or is pulled to the target tree, and the wrapping ring 32 enters the outer periphery of the tree trunk through the insertion port 3201; the nozzles 21 of the spraying assembly 2 are controlled to spray the pesticide onto the leaves and branches of the tree; simultaneously, the wrapping ring 32 is rotated, and the mounting roller 33 rotates synchronously with the wrapping ring 32, and the insect-repellent tape 300 is gradually released and wrapped around the surface of the tree trunk under the rotation of the mounting roller 33. The mobile frame 1 enables the overall movement of the device, allowing the device to approach different trees; the nozzles 21 of the spraying assembly 2 are used to spray the pesticide onto the tree, and the tape wrapping assembly 3 is used to wrap the insect-repellent tape 300 around the tree trunk, and the two are integrated on the same mobile frame 1 to achieve integrated operation.

[0030] It should be noted that the mobile frame 1 is an unmanned vehicle, and its drive system is not specifically limited here, as long as it can achieve automatic movement and flexible steering. While the mounting roller 33 rotates with the winding ring 32, it can also rotate around its own axis so that the insect-repellent tape 300 sleeved on the mounting roller 33 can be wrapped around the tree trunk. Preferably, the insect-repellent tape 300 is a special tape that is rainproof and sun-resistant, and has a smooth surface.

[0031] By integrating the spraying assembly 2 and the tape wrapping assembly 3 onto the mobile frame 1, the device simultaneously performs pesticide spraying and insect-repellent tape wrapping functions, solving the problem of separate spraying and tape wrapping operations. The insertion port 3201 of the wrapping ring 32 facilitates the entry of the tree trunk into the wrapping ring 32. With the installation roller 33 rotating with the wrapping ring 32, the insect-repellent tape 300 is automatically wrapped, reducing the steps of separate tape wrapping operations, lowering the intensity of manual labor, and improving the overall efficiency of garden pest and disease control.

[0032] For example, such as Figure 3 , Figure 4 and Figure 5As shown, in some examples, the tape wrapping assembly 3 further includes a first driver 34, a plurality of drive rollers 35, and a plurality of conveyor belts 36; specifically, the first driver 34 is disposed on the support plate 31; the plurality of drive rollers 35 are circumferentially spaced around the outer periphery of the winding ring 32; the conveyor belts 36 are of a plurality of lengths, and two adjacent drive rollers 35 are rotatably connected by a single conveyor belt 36, one of the drive rollers 35 being connected to the power output end of the first driver 34, and the first driver 34 is able to drive the plurality of drive rollers 35 to rotate synchronously via the conveyor belts 36, so that the drive rollers 35 drive the winding ring 32 to rotate.

[0033] It should be noted that the first driver 34 is a motor, which provides power to drive the winding ring 32 to rotate automatically via the drive roller 35 and the conveyor belt 36, replacing manual rotation of the winding ring 32. The power output shaft of the first driver 34 is sleeved with one of the drive rollers 35 via the conveyor belt 36. The first driver 34 drives the connected conveyor belt 36 to transmit power to the connected drive roller 35. The drive roller 35 drives the adjacent drive roller 35 to rotate synchronously via the conveyor belt 36. When all drive rollers 35 rotate, the outer circumference of the drive roller 35 abuts against the outer wall of the winding ring 32 and generates friction, so the drive roller 35 drives the winding ring 32 to rotate around its own axis, realizing the automatic winding of the insect-proof tape 300.

[0034] Furthermore, the cooperation of the first driver 34, the drive roller 35 and the conveyor belt 36 realizes the automated rotation of the winding ring 32, eliminating the need for manual rotation of the winding ring 32 and reducing the intensity of manual operation; the several drive rollers 35 are circumferentially spaced and rotate synchronously through the conveyor belt 36, which can uniformly transmit the driving force to the winding ring 32, ensuring that the winding ring 32 rotates smoothly, making the insect-proof tape 300 wrapped evenly and improving the winding quality.

[0035] For example, such as Figure 3 , Figure 4 and Figure 5 As shown, in some examples, the tape wrapping assembly 3 is provided with a limiting member 4, which includes a mounting rod 41 and two limiting rods 42. The mounting rod 41 is horizontally fixed to the top of the support plate 31 and is located on the side of the winding ring 32 away from the insertion port 3201; the upper ends of the two limiting rods 42 are slidably sleeved on the outer periphery of the mounting rod 41 through a sliding sleeve, and the lower ends of the limiting rods 42 extend toward the center of the winding ring 32.

[0036] Specifically, after the tree trunk enters the winding ring 32, the two limiting rods 42 are pushed to slide towards each other along the mounting rod 41 until the inner sidewalls of the two limiting rods 42 press against the two sides of the tree trunk respectively, thus clamping the tree trunk; while the winding ring 32 rotates to wrap the tape, the limiting rods 42 maintain the clamping state on the tree trunk.

[0037] The mounting rod 41 of the limiting member 4 provides sliding support for the limiting rod 42. The opposing sliding of the two limiting rods 42 can adapt to tree trunks of different diameters, achieving stable clamping of the tree trunk. During the tape wrapping process, the tree trunk is not prone to displacement after being limited, ensuring the relative position of the wrapping ring 32 and the tree trunk is stable, so that the insect-proof tape 300 can be wrapped in the preset position, improving the accuracy of wrapping.

[0038] For example, such as Figure 1 As shown, in some examples, the tape wrapping assembly 3 also includes a longitudinal slide rail 37 and a sliding frame 38; the longitudinal slide rail 37 is vertically mounted on the mobile frame 1; the sliding frame 38 is slidably mounted on the longitudinal slide rail 37, and the support plate 31 is mounted on the sliding frame 38. The sliding frame 38 can slide back and forth along the longitudinal slide rail 37 to adjust the height of the support plate 31.

[0039] Specifically, depending on the required height of the insect-repellent tape 300 to be wrapped around the tree trunk, the sliding frame 38 is pushed up or down along the longitudinal slide rail 37. The sliding frame 38 drives the support plate 31, the wrapping ring 32, etc., to move synchronously until the wrapping ring 32 reaches the required height. Then, the position of the sliding frame 38 is fixed, and the tape wrapping operation is carried out. The longitudinal slide rail 37 provides vertical sliding guidance for the sliding frame 38. The sliding frame 38 drives the support plate 31 and other components of the tape wrapping assembly 3 to move up and down synchronously, so that the device can adjust the wrapping position according to the height requirements of different trees, thus expanding the applicability of the device. Through height adjustment, the insect-repellent tape 300 is ensured to be wrapped in the optimal insect-repellent position on the tree trunk, improving the pest and disease control effect.

[0040] For example, such as Figure 1 As shown, in some examples, the sliding frame 38 includes a sliding seat 381 and a transverse slide rail 382. The sliding seat 381 is slidably disposed on the longitudinal slide rail 37. The transverse slide rail 382 is slidably disposed on the sliding seat 381. The transverse slide rail 382 is arranged perpendicularly to the longitudinal slide rail 37. The support plate 31 is disposed at the end of the transverse slide rail 382. The transverse slide rail 382 can slide horizontally on the sliding seat 381 to adjust the transverse position of the support plate 31.

[0041] Specifically, after adjusting the height, the horizontal slide rail 382 is pushed to slide horizontally along the sliding seat 381, causing the support plate 31 and the winding ring 32 to move closer to or further away from the tree trunk, allowing the tree trunk to accurately enter the center position of the winding ring 32 through the insertion port 3201. After the position adjustment is completed, the horizontal slide rail 382 is fixed, and then the tape wrapping operation is performed. The sliding seat 381 cooperates with the longitudinal slide rail 37 to achieve height adjustment, and the horizontal slide rail 382 cooperates with the sliding seat 381 to achieve lateral position adjustment. The combination of the two allows the winding ring 32 to be adjusted up, down, forward, and backward, ensuring that the winding ring 32 can accurately enter the tree trunk at different positions. The adjustment improves the flexibility of the device operation and further expands the applicable scenarios of the device.

[0042] For example, such as Figure 1 As shown, in some examples, the spraying assembly 2 includes a storage tank 22 and a delivery pipe 23; the storage tank 22 is fixed to the mobile frame 1; one end of the delivery pipe 23 is connected to the outlet 2201 on the side wall of the storage tank 22 via a pump body, the pipe body of the delivery pipe 23 extends to the side of the mobile frame 1, and several nozzles 21 are spaced apart along the length of the delivery pipe 23 and communicate with the interior of the delivery pipe 23. Specifically, after the pump body is started, the medicine in the storage tank 22 is pumped into the delivery pipe 23, the medicine flows along the delivery pipe 23 and is sprayed out through each nozzle 21 to cover the branches and trunks of the trees with medicine.

[0043] Understandably, the drug delivery tube 23 distributes the drug to several spaced nozzles 21, allowing the drug to be sprayed from multiple locations simultaneously, thus expanding the coverage area of ​​a single spray and improving the uniformity and efficiency of drug spraying.

[0044] For example, such as Figure 1 and Figure 6 As shown, in some examples, it should be explained that the mobile frame 1 has a movable base and a vertically extending frame. The spraying assembly 2 also includes two push rods 24, which are symmetrically fixed to the frame of the mobile frame 1. The movable ends of the push rods 24 extend upward, and the drug delivery tubes 23 are respectively disposed on the movable ends of the two push rods 24. The control units of the two push rods 24 are electrically connected and can alternately extend and retract.

[0045] Specifically, during the spraying process, the control unit controls the two push rods 24 to extend and retract alternately. When the movable end of one push rod 24 extends, the movable end of the other push rod 24 retracts, causing the delivery tube 23 to tilt to one side; conversely, the delivery tube 23 tilts to the other side, forming a vertical reciprocating swing, and the nozzle 21 expands the spraying area with the swing of the delivery tube 23.

[0046] The alternating extension and retraction of the two push rods 24 causes the delivery tube 23 to swing vertically back and forth, expanding the spraying range of the nozzle 21 from a fixed area to a certain vertical space. This increases the coverage of the medicine on different height positions of the trees, improves the comprehensiveness of the spraying, and reduces the phenomenon of missed spraying.

[0047] For example, such as Figure 1 and Figure 6 As shown, in some examples, the drug delivery tube 23 includes a horizontal tube section 231 and a vertical tube section 232. The horizontal tube section 231 extends horizontally, and the vertical tube section 232 extends vertically. The two sections intersect and communicate with each other in the middle. The tube body of the horizontal tube section 231 is connected to the movable end of the push rod 24, and several nozzles 21 are respectively and spaced apart on the tube bodies of the horizontal tube section 231 and the vertical tube section 232.

[0048] Specifically, the drug can enter both the horizontal pipe section 231 and the vertical pipe section 232 simultaneously and be sprayed out through their respective nozzles 21. Under the action of the push rod 24, the drug delivery pipe 23 swings vertically back and forth as a whole, and the nozzles 21 on the horizontal pipe section 231 and the vertical pipe section 232 move synchronously to achieve multi-directional drug coverage of the trees.

[0049] By intersecting the horizontal pipe section 231 and the vertical pipe section 232, and combining them with the nozzle 21, the pesticide can be sprayed simultaneously in both horizontal and vertical directions. This, combined with the oscillation of the delivery pipe 23, creates a three-dimensional spraying range. Compared to a single-direction delivery pipe 23, this method can more comprehensively cover the branches, leaves, and trunks of trees. The multi-directional nozzles 21 increase the contact area between the pesticide and the tree surface, enhancing the effectiveness of pest and disease control.

[0050] For example, such as Figure 6 and Figure 7 As shown, in some examples, the top of the movable end of the push rod 24 is provided with an arc-shaped seat 241. The arc-shaped seat 241 is a semi-circular arc surface facing the drug delivery tube 23. The outer arc surface of the arc-shaped seat 241 contacts the drug delivery tube 23, and the drug delivery tube 23 is placed on the outer arc surface of the arc-shaped seat 241. The spraying assembly 2 also includes two connecting rods 25. One end of each connecting rod 25 is fixedly set in the middle of the rod body of the corresponding side push rod 24, and the other end is slidably sleeved on the outer periphery of the drug delivery tube 23 through a slip ring.

[0051] Specifically, when the push rod 24 extends and retracts alternately, the delivery tube 23 swings on the outer arc surface of the arc-shaped seat 241 and can always contact the outer arc surface of the arc-shaped seat 241 during the swing. The arc-shaped seat 241 provides support and guidance for the swing of the delivery tube 23. At the same time, the end of the connecting rod 25 located in the middle of the push rod 24 is fixed. When the push rod 24 pushes the delivery tube 23, the slip ring sleeved on the delivery tube 23 can slide on the tube body of the delivery tube 23. The setting of the connecting rod 25 provides support for the delivery tube 23 and prevents the delivery tube 23 from deviating due to its own weight.

[0052] The two ends of the connecting rod 25 are connected to the push rod 24 and the drug delivery tube 23 respectively, forming a triangular support structure, which enhances the overall stability of the drug delivery tube 23, prevents it from shaking or shifting during the swinging process, ensures the accurate spraying position of the nozzle 21, and improves the consistency of the spraying effect.

[0053] For example, such as Figure 3 and Figure 4As shown, in some examples, the mounting rod 41 is a double-acting screw 411, and both ends of the double-acting screw 411 are rotatably connected to the support plate 31 through bearing seats; the upper ends of the two limiting rods 42 are provided with collars 421, the inner circumference of the collars 421 is provided with threads adapted to the double-acting screw 411, and the collars 421 are threadedly fitted onto the outer circumference of the double-acting screw 411; the limiting member 4 also includes a limiting sleeve 43 and a limiting slide plate 44, the limiting sleeve 43 is fixed on the support plate 31 and located directly below the double-acting screw 411; the limiting slide plate 44 is fixed on the support plate 31 and located above the double-acting screw 411, and the bottom surface of the limiting slide plate 44 slides against the top surface of the collar 421.

[0054] Specifically, a drive motor is used to drive the bidirectional lead screw 411 to rotate. Since the collar 421 is threadedly engaged with the bidirectional lead screw 411, and the limiting slide plate 44 restricts the collar 421 from rotating upward with the bidirectional lead screw 411, the two collars 421 drive the limiting rod 42 to slide towards or away from each other along the bidirectional lead screw 411. The limiting sleeve 43 restricts the downward swing of the limiting rod 42, ensuring that the limiting rod 42 slides in a straight line, thereby achieving stable clamping of the tree trunk.

[0055] It should be noted that the limiting slide plate 44 has a groove for the collar 421 to slide. The threaded engagement between the bidirectional lead screw 411 and the collar 421 allows the two limiting rods 42 to slide synchronously relative to each other, ensuring uniform clamping force. The limiting sleeve 43 guides the sliding of the limiting rod 42, so that the collar 421 can only slide within the groove. The limiting sleeve 43 and the limiting slide plate 44 restrict the radial movement of the limiting rod 42 and the collar 421, ensuring that the limiting rod 42 slides smoothly and is accurately positioned, improving the clamping reliability for tree trunks of different diameters, and further ensuring the accuracy of tape wrapping.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
