Description

Technical Field

[0001] This invention relates to the technical field of plant protection vehicles, and in particular to a combing and spraying type unmanned plant protection vehicle. Background Technology

[0002] Currently, plant protection operations in greenhouse facilities generally involve manual backpack sprayers entering the planting area or installing rails on the top of the planting area and using mobile nozzles for spraying. Most existing spraying equipment is top-mounted, only covering the upper surface of the leaves with pesticide, offering no effect on pests and diseases on the underside of the leaves. A few so-called omnidirectional spraying devices simply add several nozzles at fixed angles for lateral and bottom-up spraying, failing to cover all spray angles. Simultaneous spraying from all nozzles often results in leaf folding and branch bending, failing to ensure even pesticide coverage on both sides of the leaves. In high-density planting, manual backpack sprayers cannot even enter the cultivation area for spraying. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The purpose of this invention is to provide a combing and spraying unmanned plant protection vehicle to solve the problems existing in the prior art, so as to make the liquid spray evenly on both sides of the leaves and improve the spraying effect of the liquid.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 7 As shown: This embodiment provides a combing and spraying type unmanned plant protection vehicle, including a walking chassis 1, a roller nozzle assembly, a circulating transmission mechanism, a support frame 13, and a control unit. The walking chassis 1 is equipped with the support frame 13, and the support frame 13 is equipped with the circulating transmission mechanism. The roller nozzle 2 of the roller nozzle assembly is connected to the circulating transmission mechanism. The roller nozzle 2 can rotate and rise and fall with the circulating transmission mechanism. The walking chassis 1, the roller nozzle assembly, and the circulating transmission mechanism are all communicatively connected to the control unit. The walking chassis 1 can be a four-wheel walking mechanism or a tracked walking mechanism commonly used in the art; the specific structure will not be described in detail here.

[0030] As a preferred embodiment, the roller nozzle assembly in this embodiment includes a roller nozzle 2, a liquid storage tank 3, and a pump body 4. The liquid storage tank 3 is mounted on the chassis 1, and the pump body 4 is mounted inside the liquid storage tank 3. The pump body 4 is connected to the center of the roller nozzle 2 through a liquid outlet pipe 5 for rotational sealing, which avoids entanglement while ensuring the sealing of the liquid supply.

[0031] As a preferred embodiment, the roller nozzle 2 includes several circumferentially distributed nozzles 6. The roots of the nozzles 6 are interconnected at the center, and each nozzle is provided at its outer end. One side of the center is connected to the rotor of a disc motor 10, and the other side is rotatably and sealingly connected to a bent pipe 7. One end of the bent pipe 7 is fixedly connected to the rotating shaft of the disc motor 10 through a hollow connecting ring 11, and the other end is connected to the liquid outlet pipe 5. The connecting ring 11 is located in the central connecting cavity, ensuring both the rotation of the nozzles 6 and the sealing of the liquid supply. The disc motor 10 is fixed on a connecting plate 20, which is set on a circulating transmission mechanism. The roller nozzle 2 is preferably an integrally cast part. A counterweight 12 is preferably provided on the other end of the connecting plate 20 to maintain the force balance at both ends of the connecting plate 20.

[0032] As a preferred embodiment, the liquid outlet pipe 5 is vertically mounted on the support frame 13. The liquid outlet pipe 5 is preferably a flexible hose. The bend pipe 7 is horizontally oriented towards the inside of the walking chassis 1 and is connected to the liquid outlet pipe 5 through a metal flexible hose 9. The spray pipe 6 is L-shaped. The end of the short pipe of the L-shape is equipped with a nozzle, and when the long pipe is horizontal, the short pipe can be vertically upward, which can realize dynamic teasing of the leaf surface and spraying of the liquid on the surface.

[0033] As a preferred embodiment, two sets of roller nozzle assemblies are arranged symmetrically at the center. The end of the liquid outlet pipe 5 is fixed to the support frame 13 and a tee 8 is provided with a rotatable seal. The tee 8 is connected to a metal hose 9. The tension of the metal hose 9 at its two farthest positions causes the tee 8 to rotate. At other times, the metal hose 9 can maintain a certain curvature without bending, thus maintaining the flow of liquid. Alternatively, the tee 8 can be inserted into a driven gear 17, driving the tee 8 to rotate. The driven gear 17 meshes with a driving gear 18, and the driving gear 18 is connected to the shaft of a motor 19. The rotation speed of the driving gear 18 can be controlled by the control unit to prevent the metal hose 9 from tangling.

[0034] As a preferred embodiment, in this embodiment, the roller nozzle 2 is rotatably disposed within a U-shaped protective groove 14, which is fixed to the connecting plate 20. The opening of the protective groove 14 can be horizontally oriented towards the outside of the walking chassis 1. The length of the spray pipes 6 can extend out of the opening of the protective groove 14. When one spray pipe 6 of the roller nozzle 2 extends out of the protective groove 14, the remaining spray pipes 6 are all located within the protective groove 14. Only the nozzles between the upper horizontal and vertical directions can spray the liquid towards the plants on both sides, which can prevent the liquid from being sprayed onto the walking chassis 1 and also prevent the lower and inner nozzles from failing to spray onto the plants, thus avoiding waste.

[0035] As a preferred embodiment, the bottom of the protective trough 14 is provided with a return hole 15, and a collection trough 16 is provided on the walking chassis 1. The collection trough 16 can collect the liquid leaking from the return hole 15, and the collection trough 16 is connected to the storage tank 3 through a pipeline. When two sets of roller nozzle assemblies are symmetrically arranged in the center, it is preferable to provide a protective trough 14. The protective trough 14 blocks the liquid sprayed towards the walking chassis 1. The liquid flows from the return hole 15 at the bottom of the protective trough 14 into the collection trough 16, and then flows back to the storage tank 3, realizing large-area multi-angle spraying while avoiding liquid waste.

[0036] As a preferred embodiment, the circulating transmission mechanism includes a sprocket transmission mechanism 20 or a pulley synchronous belt transmission mechanism. The support frame 13 is a vertically arranged support rod. The sprocket transmission mechanism 20 or the pulley synchronous belt transmission mechanism is vertically arranged on the support frame 13. The height of the support frame 13 matches the height of the sprayed plants. A roller nozzle assembly is fixedly connected to the chain or synchronous belt through a connecting plate 20, which drives the roller nozzle assembly to rotate cyclically.

[0037] As a preferred embodiment, two photoelectric sensors 22, proximity switches, or electromagnetic sensors are respectively installed on both sides of the liquid storage tank 3. The installation positions of the photoelectric sensors 22 or proximity switches are matched with those of the roller nozzle assembly. Both photoelectric sensors 22 or proximity switches are communicatively connected to the control unit. The control unit can control whether the roller nozzle assembly sprays liquid based on the signal changes of the photoelectric sensors 22 or proximity switches. The two photoelectric sensors 22 or proximity switches are located on both sides of the sprocket or pulley. When the roller nozzle assembly rotates to the first photoelectric sensor 22 and blocks the light, the controller controls the pump body 4 to turn off. When the roller nozzle assembly rotates to the second photoelectric sensor 22 and blocks the light, the controller controls the pump body 4 to turn on. This cycle repeats, ensuring that the roller nozzle assembly does not spray liquid when it is at the bend of the sprocket, but only sprays liquid in the vertical lifting section, achieving precise application and avoiding waste.

[0038] In this embodiment, the unmanned plant protection vehicle that performs combing and spraying can spray pesticides after entering a row. Figure 1 and Figure 2 As shown, the roller nozzle assembly rotates counterclockwise. The nozzle on the left mainly sprays the underside of the leaves, while the nozzle on the right mainly sprays the topside. Reaching the end of the row, it turns around and sprays the other side, ensuring that both the top and bottom surfaces of the leaves on both sides of the same row are covered with the pesticide. Simultaneously, the pesticide jet mimics the action of a hand combing through branches and leaves, achieving coverage of all spray angles, thoroughly spraying and removing pests and diseases from both sides of the leaves. It also avoids leaf stacking and branch bending or entanglement, ensuring the pesticide fully and evenly covers both sides of the leaves, improving the effectiveness of plant protection operations in high-density cultivation environments within greenhouse facilities.

[0039] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
