Description

Technical Field

[0001] The present invention relates to the technical field of plant protection machines, and in particular to an agricultural plant protection machine. Background Art

[0002] The full name of the plant protection machine is plant protection machine. Plant protection machines can effectively prevent and control crop diseases and pests, reduce the use of pesticides, and at the same time reduce environmental pollution. In complex terrain (such as paddy fields and hills), drone plant protection machines are particularly efficient and flexible in operation, significantly improving agricultural production efficiency and sustainability.

[0003] For example, Chinese patent publication No. CN119422482A discloses a multifunctional self-propelled plant protection machine, comprising a base, a water tank being provided on the left side of the upper end of the base, a water inlet pipe being provided in the water inlet opened at the front end of the water tank, a water inlet valve being connected in series on the front side of the water inlet pipe, a lower hopper being provided in the mounting grooves opened on the front and rear sides of the upper end of the base, vertical plates being provided on the right side of the upper end of the base, the upper sides of the two vertical plates relative to the inner sides are rotatably connected to mounting columns, a fixed seat being provided on the left side of the lower end of the base, the side of the fixed seat away from the inner center of the base is rotatably connected to a mounting rod, and the outer arc surface of the mounting rod is provided with an anti-slip roller. The multifunctional self-propelled plant protection machine improves the tillage effect, solves the problem of multiple tillage operations being required due to hard soil in some areas, improves the coverage of pesticide spraying, and can adapt to different crop layouts and row spacings.

[0004] This type of plant protection machine can only spray pesticides in a fixed amount within a unit area. However, the degree of insect pests in different areas of the same field varies. It is difficult for traditional plant protection machines to accurately adjust the amount of pesticide spraying based on these differences, resulting in inaccurate pesticide spraying. This may not only lead to waste of pesticides and increase agricultural production costs, but may also cause environmental pollution and excessive pesticide residues in agricultural products due to excessive pesticide spraying, endangering the ecological environment and human health. Insufficient spraying cannot effectively control insect pests, affecting crop yield and quality. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] See also Figures 1 to 12 The present invention provides a technical solution: an agricultural plant protection machine, comprising a driving head 1, an image acquisition device mounted on the top of the driving head 1, a medicine loading hopper 2 fixedly connected to the rear of the driving head 1, a water storage bucket 34 fixedly mounted on the top of the medicine loading hopper 2, a mounting frame 3 mounted on the rear of the medicine loading hopper 2, a first spraying part and a second spraying part fixedly connected to the outer wall of the mounting frame 3, and the first spraying part and the second spraying part both comprising a plurality of nozzles;

[0036] It also includes an adjustment component, which can adjust the spray force of the nozzle of the second spraying part;

[0037] The utility model also comprises a switching component, which can control the opening and closing of the first spraying part and can adjust the spraying range of the nozzle of the second spraying part.

[0038] See Figure 1 When the agricultural plant protection machine is operating in the field, the image acquisition device on the top of the driving vehicle 1 first takes real-time photos of the area in front of the field to obtain the pest situation in the front area of the field. The image acquisition device feeds the collected image information back to the internal control system of the plant protection machine, and the control system determines the degree of pest damage:

[0039] When the device is in use, the disaster situation is divided into three levels, namely light, medium and heavy, which also correspond to three adjustment modes. In the initial mode, the device defaults to the medium level. At the medium level, the first spraying unit and the second spraying unit are started at the same time, as shown in the water inlet pipe 10 in the figure, where the dotted line a (first spraying range) represents the projection of the pesticide sprayed by the nozzle, that is, the horizontal spraying range of each nozzle. As shown in the figure, in the initial mode (moderate disaster), the spraying range of each nozzle just intersects, that is, one spraying unit can spray the field it passes through once, and at this time, the spraying range of the nozzles of the two spraying units are both as shown by the dotted line a in the figure, thereby spraying the field it passes through twice. This design realizes centralized prevention and control of moderate insect pest areas. Through the coordinated operation of the two spraying units, the effective coverage area and prevention and control effect of the pesticide are improved, ensuring that moderate insect pests can be controlled in a timely and effective manner.

[0040] When the control system determines that the field ahead is slightly damaged, the switching component turns off the first spraying unit and activates only the second spraying unit to spray pesticides, so that the nozzles in the second spraying unit only spray the field below once, thereby reducing the amount of pesticide used and avoiding pesticide waste and environmental pollution.

[0041] Referring to the rotating cylinder 12 in the figure, when the control system determines that the field ahead is severely damaged, the switching component controls the first spraying unit and the second spraying unit to start simultaneously, and at the same time increases the spraying range of the second spraying head. During this process, the adjusting component controls the spraying force of the nozzle of the second spraying unit to increase, so that the pesticide sprayed by the nozzle in the second spraying unit can still be sprayed to the farthest position, as shown by the dotted line b (second spraying range) in the fixed cylinder 11 in the figure. The spraying range of each nozzle not only covers its own initial spraying area, but also extends to half of the initial spraying area of the adjacent nozzle, that is, the spraying ranges of adjacent nozzles overlap with each other, so that the fields passed by can be sprayed with pesticides three times. This can ensure that the severely disaster-stricken areas are more fully covered by pesticides and improve the prevention and control effect. This device divides the degree of disaster into three levels and increases the amount of pesticides applied to unit fields from light to heavy, thereby achieving precise pesticide application in areas with different pest levels. This not only ensures the effectiveness of pest control, but also avoids excessive use of pesticides, reduces environmental pollution, lowers agricultural production costs, improves pesticide utilization efficiency, provides guarantees for the healthy growth of crops, and contributes to the sustainable development of agriculture.

[0042] Among them, it is worth noting that the image acquisition device can adopt industrial-grade high-definition cameras and intelligent agricultural detection cameras 7, etc.

[0043] Furthermore, the second spraying part includes a second mounting bracket 5 fixedly connected to the outer wall of the mounting frame 3, and the outer wall of the second mounting bracket 5 is fixedly connected to a fixed cylinder 11, which is connected to the water storage barrel 34. The outer wall of the fixed cylinder 11 is provided with several liquid storage chambers 14 connected to its interior, and the front end of each liquid storage chamber 14 is connected to an elastic nozzle 9.

[0044] Furthermore, a plurality of first partition plates 19 are fixedly mounted on the inner wall of the fixed cylinder 11. Each two adjacent first partition plates 19 together form an independent regulating chamber. Each liquid storage chamber 14 is respectively mounted in the corresponding regulating chamber. The regulating assembly is composed of a plurality of regulating parts and a solenoid valve mounted in the first spraying part.

[0045] Each regulating part includes two second partition plates 20 fixedly mounted on the inner wall of the regulating chamber. The two second partition plates 20 respectively form a pressure chamber with the adjacent first partition plates 19. The two pressure chambers are connected to the water storage barrel 34 through the water inlet hole 27, and the two pressure chambers are connected to the liquid storage chamber 14 through the connecting pipe 33. The outer wall of the two second partition plates 20 close to the first partition plate 19 is fixedly mounted with an elastic air bag 21. Two slidable piston plates 22 are installed in the regulating chamber. The two piston plates 22 respectively form an air storage chamber with the adjacent second partition plates 20. The two elastic air bags 21 are connected to the corresponding air storage chambers.

[0046] See Figure 5 and Figure 7The interior of the fixed cylinder 11 is divided into several regulating chambers by multiple first partition plates 19. Two elastic air bags 21 are installed in each regulating chamber, thereby dividing the left and right sides of the regulating chamber into two pressure chambers. Each pressure chamber is connected to the water storage barrel 34 through the water inlet hole 27. The external water pump collects the water in the water storage barrel 34 into the pressure chamber through the water inlet hole 27. When the pressure chamber is filled, it will be transported to the liquid storage chamber 14 through the connecting pipe 33, and then the pesticide will be sprayed out through the elastic nozzle 9.

[0047] In the initial stage (i.e., during moderate disasters), the two piston plates 22 are located at the farthest distance. The piston plates 22 will squeeze the air in the air storage chamber into the elastic airbag 21, thereby expanding the elastic airbag 21. The expanded elastic airbag 21 will occupy part of the space in the pressure chamber, thereby increasing the pressure in the pressure chamber. At this time, a part of the power of the liquid entering the pressure chamber through the water inlet hole 27 will be used to offset the reaction force generated by the expansion of the elastic airbag 21, which will reduce the power of the liquid entering from the water inlet hole 27 and flowing to the connecting pipe 33, and ultimately reduce the power of the liquid sprayed from the elastic nozzle 9 to reduce the spraying intensity, and the spraying range at this time is the initial first spraying range.

[0048] When the disaster is severe, the two piston plates 22 are moved closer to each other through an external driving component, thereby reducing the pressure in the air storage chamber, and then the air in the elastic airbag 21 is extracted into the air storage chamber. At this time, the elastic airbag 21 is in a flat state, the pressure in the pressure chamber disappears, and the liquid flowing into the connecting pipe 33 through the water inlet hole 27 is unpowered and attenuated, thereby increasing the injection power of the elastic nozzle 9, and the injection range of the elastic nozzle 9 is increased by adjusting the component (i.e., the second injection range), thereby completing efficient prevention and control of severe disaster areas.

[0049] Furthermore, a rotatable rotating cylinder 12 is installed on the inner wall of the adjusting chamber, an arc-shaped groove 18 is provided on the outer wall of the fixed cylinder 11, and a connecting rod 13 is fixedly connected to the outer wall of the rotating cylinder 12. The connecting rod 13 passes through the arc-shaped groove 18 and extends out of the outside of the fixed cylinder 11 and is fixedly connected to the outer wall of the liquid storage chamber 14. A torsion spring 25 is installed between the outer wall of the rotating cylinder 12 and the inner wall of the fixed cylinder 11. Two cam grooves 26 are provided on the inner wall of the rotating cylinder 12, and the two cam grooves 26 are both oblique grooves when unfolded. The outer walls of the two piston plates 22 are fixedly installed with piston rods 23, and the outer walls of the two piston rods 23 are fixedly installed with fixed shafts 24. The two fixed shafts 24 slide in the corresponding cam grooves 26.

[0050] See Figure 5When the disaster level is detected to be severe, the external driving component drives the rotating cylinder 12 to rotate to overcome the elastic force of the torsion spring 25, and the rotating cylinder 12 drives the liquid storage chamber 14 to rotate through the connecting rod 13. At the same time, the cam groove 26 on the inner wall of the rotating cylinder 12 interacts with the fixed shaft 24 on the outer wall of the piston rod 23, converting the rotation of the rotating cylinder 12 into the sliding of the piston plate 22 in the adjustment chamber, thereby changing the volume and pressure of the storage air chamber, and then causing the elastic airbag 21 to contract, eliminating the resistance to the liquid in the pressure chamber, and allowing the liquid to flow into the liquid storage chamber 14 without power attenuation, thereby increasing the spray power of the elastic nozzle 9, and expanding the spray range through the adjustment component to complete effective prevention and control of severe disaster areas. This design cleverly converts rotational motion into linear motion, realizing precise adjustment of spray parameters.

[0051] Furthermore, the switching assembly includes a sliding shell 15 slidably mounted on the outer wall of the liquid storage chamber 14, and the upper and lower inner walls of the sliding shell 15 are both installed with extrusion plates 32 that can squeeze the elastic nozzle 9. A pull rope 17 is fixedly installed on one end of the sliding shell 15 close to the fixed cylinder 11, and the other end of the pull rope 17 is fixedly connected to the outer wall of the arc groove 18. A spring 16 is connected between the sliding shell 15 and the liquid storage chamber 14.

[0052] See Figure 4 , Figure 4 It is the initial state. At this time, under the action of the external driving component, the connecting rod 13 and other components overcome the elastic force of the torsion spring 25 and rotate to a horizontal state. At this time, the sliding shell 15 is elastically moved to the farthest point under the action of the spring 16. The elastic nozzle 9 is not compressed at this time, and the spray range is the first spray range.

[0053] When the disaster is severe, the external drive component is released, and the rotating cylinder 12 is rotated downward under the elastic force of the torsion spring 25. Under the action of the pull rope 17, the liquid storage chamber 14 will gradually move toward the connecting rod 13, thereby compressing the spring 16. At this time, the two extrusion plates 32 will squeeze the middle part of the elastic nozzle 9 (this extrusion effect is similar to pinching a water pipe), and cooperate with the contraction of the elastic airbag 21 to increase the spray range of the elastic nozzle 9, so that it can cover a wider area in severe disasters and improve the prevention and control effect. This design achieves rapid adjustment of the nozzle spray range through a simple mechanical structure, without the need for a complex control system, thereby improving the practicality and adaptability of the plant protection machine.

[0054] Furthermore, in the initial state, two adjacent elastic nozzles 9 are alternately arranged to face upward and downward.

[0055] The staggered spray directions of adjacent elastic nozzles 9 can reduce mutual interference between sprays, allowing pesticides to reach the target area more accurately. Especially for tall crops or densely planted farmland, this design can effectively prevent pesticides from drifting and spreading in the air.

[0056] Furthermore, a first arc-shaped cover 28 and a second arc-shaped cover 29 are rotatably mounted on the outer wall of the fixed cylinder 11, and an inner gear ring 31 is coaxially fixedly mounted on the outer walls of the first arc-shaped cover 28 and the second arc-shaped cover 29. Rotatable drive gears 30 are mounted on the outer walls of both sides of the second mounting bracket 5, and the two drive gears 30 are engaged with the corresponding inner gear ring 31.

[0057] See Figure 6 In the initial state, the first curved cover 28 and the second curved cover 29 maintain their initial positions under the meshing action of the drive gear 30 and the inner gear ring 31, so that the elastic sprinkler 9 is in the default spraying state of moderate disasters, ensuring uniform coverage; when the disaster level changes to severe, the motor fixed to the outer wall of the second mounting bracket 5 drives the drive gear 30 to rotate, thereby driving the first curved cover 28 and the second curved cover 29 to rotate, thereby completing the unlocking of the connecting rod 13, and resetting the rotating cylinder 12 under the action of the torsion spring 25, so as to complete the above-mentioned purpose of adjusting the spraying range of the elastic sprinkler 9.

[0058] Furthermore, the mounting frame 3 and the medicine loading hopper 2 are detachable, and the mounting frame 3 can be rotated 180 degrees and mounted on the outer wall of the medicine loading hopper 2 .

[0059] See Figure 1 as well as Figure 2 , Figure 2 This is a schematic diagram of the mounting frame 3 being mounted on the drug hopper 2. At this time, the mounting frame 3 is angled downward, which is suitable for conventional field operations. The spraying direction is downward, and the field can be sprayed directly.

[0060] When it is necessary to spray tall crops or a specific area, the mounting frame 3 can be disassembled and reinstalled after being rotated 180 degrees. At this time, the mounting frame 3 is angled upward (such as Figure 1 As shown in the figure, the spraying direction changes, and higher crops can be sprayed. This design increases the flexibility and applicability of the plant protection machine, enabling it to better cope with different types of crops and complex field environments.

[0061] Furthermore, the first spraying part includes a first mounting bracket 4 fixedly connected to the outer wall of the mounting frame 3 , the inner wall of the first mounting bracket 4 is also fixedly connected to a fixed cylinder 11 , and the outer wall of the fixed cylinder 11 is fixedly mounted with a plurality of fixed nozzles 8 .

[0062] See Figure 3 The outer wall of the first mounting bracket 4 is also installed with a fixing cylinder 11, and the interior of the fixing cylinder 11 is also connected to the water storage barrel 34 through the water inlet pipe 10, and a solenoid valve is installed inside the water inlet pipe 10, which is opened by the control system.

[0063] Furthermore, a shockproof mounting plate 6 is fixedly installed on the top of the driving vehicle head 1, and an intelligent agricultural detection camera 7 is installed on the outer wall of the shockproof mounting plate 6.

[0064] The image acquisition device used in the present invention is an intelligent agricultural detection camera 7. The intelligent agricultural detection camera 7 is specially designed for agricultural monitoring. It has high definition and good low-light performance. It can transmit images in real time and support intelligent analysis functions, such as automatic identification of pest types and quantities. It has outdoor protection functions such as waterproof and dustproof. It can monitor and feedback pest conditions in real time, providing data support for the precise spraying of plant protection machines.

[0065] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

[0066] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
