[0001] This utility model relates to the field of agricultural technology, and in particular to a portable agricultural pest control device. Background Technology

[0002] Crops inevitably suffer from pest infestations during their growth process, generally requiring pesticide spraying to control pests and increase crop yields. Existing pesticide control devices are generally backpack sprayers or vehicle-mounted sprayers. Backpack sprayers are suitable for small fields or home use; vehicle-mounted sprayers are suitable for large-scale planting areas or commercial use.

[0003] The applicant has discovered that the existing technology has at least the following technical problems: The existing backpack insecticide device includes a medicine box, a shoulder strap, and a spray gun; during use, the medicine box needs to be carried on the body continuously, which is not only heavy and labor-intensive, but also requires the operator to squat down and stand up when placing the medicine box on the ground, which is inconvenient and does not allow for breaks; secondly, the existing insecticide device only protects the hands through part of the structure, and in fact, during the insecticide application process, the mist-like liquid can enter the mouth, nose, or eyes of the human body under the action of airflow, causing harm to the human body. Utility Model Content

[0004] The purpose of this invention is to provide a portable agricultural pest control device to solve the aforementioned technical problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a portable agricultural insecticide device, including a medicine box, a carrying strap, a spray gun, a pressurizing device, and retractable support legs; wherein:

[0007] The carrying straps are located on both sides of the medicine box;

[0008] There are two spray guns, which are connected to the bottom sides of the medicine tank via hoses;

[0009] The pressurization device is located on the top of the medicine box;

[0010] The retractable support legs are located at the bottom of the pesticide container. By incorporating these retractable support legs, the container can be supported on the ground without needing to be carried on the back, thus reducing the workload of the sprayer. Furthermore, by adjusting the height of the support legs, it can adapt to different terrains and crop heights, improving the applicability and ease of operation of the device. In addition, the retractable design of the support legs facilitates carrying and storage, further enhancing portability.

[0011] A further improvement of this invention is that the retractable support leg is made of aluminum alloy.

[0012] The aluminum alloy support legs not only offer high strength and durability but also effectively reduce overall weight, making the device more portable and easier for operators to use for extended periods. Furthermore, the aluminum alloy surface undergoes anti-corrosion treatment, enabling it to withstand complex field environments and extending its service life.

[0013] As a further improvement of this utility model, the retractable support leg includes a fixed tube and a movable rod. The movable rod is slidably inserted into the fixed tube and fixed by a pin. The pin-fixing method allows for quick adjustment and locking of the support leg height, making operation simple, stable, and reliable, meeting the needs of different application scenarios. Furthermore, the tight fit between the fixed tube and the movable rod prevents shaking from affecting the stability of the device, thereby improving the safety and efficiency of application operations. In use, without lowering the medicine box, the operator can pull out the movable rod and then insert the pin to fix it, providing support for the medicine box without lowering it. This facilitates breaks for the operator, reduces weight-bearing capacity, and lowers labor intensity.

[0014] As a further improvement of this utility model, a through hole is provided at the lower part of the fixed tube; several locking holes are provided along the axial direction on the movable rod; one end of the pin is connected to the fixed tube or the medicine box via a rope, and the other end passes through the through hole and is fixed by engaging with any one of the locking holes. By setting the engaging structure of the through hole and locking holes, the pin can be fixed at different heights, thus meeting the needs of different terrains and crop heights. At the same time, the connection design between the pin and the rope effectively prevents the pin from accidentally falling off or being lost during use, ensuring the safety and stability of the device. This structure is simple, practical, and easy to operate, not only improving the applicability of the device but also further enhancing the user-friendly design of the portable agricultural insecticide device, providing sprayers with a more efficient and labor-saving working experience.

[0015] As a further improvement of this utility model, a swivel caster is provided at the bottom of the movable rod. By providing the swivel caster at the bottom of the movable rod, the medicine box can be pulled when the movable rod is retracted, and the medicine box can be dragged when the movable rod is extended, facilitating movement. The swivel caster design effectively reduces the resistance for the sprayer when moving in the field, making movement easier and more flexible, especially on uneven field surfaces, where the swivel caster can flexibly turn, adapt to complex terrain, and reduce the physical exertion of the sprayer. Furthermore, the caster is made of wear-resistant and non-slip materials, possessing good corrosion resistance and durability, and can operate stably in wet and muddy environments, further improving the practicality and work efficiency of the device.

[0016] As a further improvement of this utility model, the number of retractable support legs is two, and the two retractable support legs are symmetrically arranged on both sides of the bottom of the medicine tank. The symmetrical arrangement of the retractable support legs on both sides effectively improves the support stability of the medicine tank, ensuring the overall balance and safety of the device during application. When operating on complex terrain or slopes, the two support legs can be independently adjusted according to the ground undulations, keeping the medicine tank level and avoiding problems such as spillage or uneven spraying due to tilting. At the same time, the symmetrically arranged support leg structure can effectively distribute the weight of the medicine tank, reduce pressure on one side, and extend the service life of the device. This design not only improves the convenience and adaptability of application operations but also further ensures the safety and reliability of field operations, providing excellent support for the practicality and efficiency of agricultural pesticide application equipment.

[0017] As a further improvement of this utility model, the spray gun is provided with a plurality of nozzles, all of which are arranged sequentially at intervals along the axial direction of the spray gun. By providing multiple nozzles at intervals along the axial direction, the pesticide solution can form a uniform atomization effect during spraying, covering a wider area and improving the uniformity of application and work efficiency. The layout of multiple nozzles can effectively avoid spraying blind spots, ensuring that the pesticide fully covers the crop surface and improving the control effect. At the same time, the axial spacing can reduce mutual interference between nozzles and reduce the phenomenon of pesticide collision and backflow, thereby improving spraying stability.

[0018] As a further improvement of this utility model, the spray gun is fitted with a detachable gun holster made of plastic. By providing the gun holster, it can be removed during use and sealed when stored to prevent liquid dripping, while maintaining the cleanliness of the equipment and preventing residual liquid from polluting the environment. Furthermore, the gun holster is made of lightweight plastic, combining durability and portability, allowing for quick disassembly and cleaning by the user.

[0019] As a further improvement of this utility model, a filter screen is installed inside the medicine tank to prevent impurities from clogging the nozzles and extend the service life of the equipment. The filter screen is located at the liquid outlet of the medicine tank and can effectively intercept solid impurities and undissolved particles in the liquid, preventing nozzle clogging from affecting the spraying effect. This filter screen adopts a multi-layer structure design, possessing high filtration accuracy and permeability, while also being easy to disassemble, clean, or replace, ensuring that the equipment maintains a good working condition during long-term use. Furthermore, the presence of the filter screen reduces the frequency of equipment maintenance, improves the continuity and efficiency of pesticide application, and provides more stable and reliable support for field management.

[0020] As a further improvement of this utility model, the filter screen is detachable, facilitating cleaning and replacement and ensuring smooth flow of pesticide solution. The device has a simple overall structure and is easy to operate, suitable for pest and disease control of various crops, and possesses strong practicality and promotional value. By adopting a detachable filter screen design, users can quickly clean or replace the filter without the need for specialized tools, significantly reducing the difficulty and time cost of equipment maintenance. Simultaneously, this structural design fully considers the applicability of different pesticide components, effectively preventing impurities from accumulating and obstructing flow even when using high-concentration or residue-prone pesticides. This convenient and optimized filtration system design provides strong support for the efficient and stable operation of the portable insecticide device, while also extending the overall service life of the equipment, making it suitable for pesticide application needs in various complex farmland environments.

[0021] As a further improvement of this utility model, it also includes a support frame, a ring frame, and a protective cover; wherein:

[0022] The support frame is located on top of the medicine box;

[0023] The ring frame is located above the human head and is connected to the support frame;

[0024] The top of the protective cover is fitted onto the annular frame and can be pulled open or retracted along the extension direction of the annular frame.

[0025] The protective cover can slide and adjust its position along the ring frame, similar to a shower curtain structure. The diameter of the enclosure can be adjusted according to the user's situation to prevent the sprayed liquid from entering the face, mouth or nose of the sprayer, thereby effectively protecting the health and safety of the sprayer.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] like Figures 1-7 As shown, this utility model provides a portable agricultural insecticide device, including a medicine box 1, a carrying strap 2, a spray gun 3, a pressurizing device, and retractable support legs 200; wherein:

[0037] The carrying straps 2 are set on both sides of the medicine box 1 to form a double shoulder carry structure; of course, the carrying straps 2 can adopt an adjustable length structure to suit people of different body types.

[0038] There are two spray guns 3, each connected to the bottom of the medicine tank 1 via hoses. By installing spray guns 3 on both sides, simultaneous spraying on both sides can be performed as needed, greatly improving work efficiency. Alternatively, one spray gun 3 can be selected for application depending on whether the plant is located to the side of the operator, expanding the applicability of the device and making it more flexible in use. It should be noted that hooks 4 are provided on the side of the medicine tank 1 to hold the spray guns 3 in place. When not in use, the spray guns 3 are secured in the hooks 4 to prevent them from shaking during movement. Once the spray guns 3 are fixed in place by the hooks 4, the operator does not need to hold them while moving, greatly improving portability and safety.

[0039] The pressurization device is located at the top of the medicine tank 1; it is used to establish the liquid delivery pressure in the medicine tank 1 to ensure the continuity and efficiency of the spraying operation.

[0040] The retractable support leg 200 is located at the bottom of the pesticide tank 1. By incorporating the retractable support leg, the pesticide tank 1 can be supported on the ground without needing to be carried on the back, thereby reducing the labor intensity of the sprayer. Simultaneously, by adjusting the height of the support leg, it can adapt to different terrains and crop heights, improving the applicability and ease of operation of the device. Furthermore, the retractable design of the support leg facilitates carrying and storage, further enhancing portability. Through the above structural design, this utility model achieves a balance between lightweight design, portability, and efficient pest control, meeting the dual demands of convenience and safety in modern agricultural operations.

[0041] It should be noted that, while improving ease of use, this invention employs the following design to reduce the overall weight of the insecticidal device: the retractable support leg 200 is made of aluminum alloy. Of course, the retractable support leg 200 can also be made of other lightweight alloy materials, which are not only high-strength but also lightweight and easy to carry. Meanwhile, the medicine box 1 is made of high-density polyethylene, which has good corrosion resistance and impact resistance, extending the device's service life. Furthermore, the outer shell of the spray gun 3 is also made of engineering plastic, further reducing the overall weight. Through these designs, while ensuring the stability and durability of the device, the physical exertion of the operator is minimized, and work efficiency is improved, demonstrating strong practicality and promotional value.

[0042] The aluminum alloy support legs not only offer high strength and durability but also effectively reduce overall weight, making the device more portable and easier for operators to use for extended periods. Furthermore, the aluminum alloy surface undergoes anti-corrosion treatment, enabling it to withstand complex field environments and extending its service life.

[0043] As an optional embodiment of this utility model, the telescopic support leg 200 includes a fixed tube 201 and a movable rod 202. The movable rod 202 is slidably inserted into the fixed tube 201 and fixed by a pin 204.

[0044] It should be noted that, in order to increase the support height of the retractable support leg 200, ensuring that it can reach the ground when the operator is resting (i.e., when carrying the medicine box 1), the bottom of the retractable support leg 200 should touch the ground when extended to its maximum length, with the bottom of the fixed tube 201 parallel to the bottom of the medicine box 1, but the top of the fixed tube 201 extending beyond the top of the medicine box 1, and the extended portion serving as a handle for easy gripping of the medicine box 1 during movement), the top of the fixed tube 201 is sealed to prevent the movable rod 202 from protruding from the top of the fixed tube 201. The length of the movable rod 202 should be slightly greater than the length of the fixed tube 201, so that a portion remains exposed when retracted into the fixed tube 201, preventing it from being unable to be pulled out later. Furthermore, a locking mechanism, namely a pin 204, is provided between the fixed tube 201 and the movable rod 202 to adjust and fix the extension length of the support leg, ensuring that the support leg can stably support the medicine box 1 under different terrain conditions. The locking mechanism is simple in structure and easy to operate. By inserting the pin 204 into the positioning holes of different heights, the height of the support leg can be flexibly adjusted.

[0045] The height of the support leg can be quickly adjusted and locked using the pin 204, making operation simple, stable, and reliable, meeting the needs of different application scenarios. Furthermore, the tight fit between the fixed tube 201 and the movable rod 202—meaning the inner diameter of the fixed tube 201 and the outer diameter of the movable rod 202 are equal or have a small gap—prevents swaying from affecting the stability of the device, thereby improving the safety and efficiency of the application operation. During use, without lowering the medicine box 1, the operator can pull out the movable rod 202 and then insert the pin 204 for fixation. This allows for support of the medicine box 1 without lowering it, facilitating breaks for the operator, reducing weight-bearing capacity, and lowering labor intensity.

[0046] In this embodiment, a through hole 203 is provided at the lower part of the fixed tube 201; several locking holes 205 are provided along the axial direction on the movable rod 202; one end of the pin 204 is connected to the fixed tube 201 or the medicine box 1 via a rope, and the other end passes through the through hole 203 and is fixed by engaging with any one of the locking holes 205. By setting the engaging structure of the through hole 203 and the locking hole 205, the pin 204 can be fixed at different heights, thereby meeting the usage requirements of different terrains and crop heights. At the same time, the connection design between the pin 204 and the rope effectively prevents the pin 204 from accidentally falling off or being lost during use, ensuring the safety and stability of the device. This structure is simple and practical, easy to operate, not only improving the applicability of the device, but also further enhancing the humanized design of the portable agricultural insecticide device, providing sprayers with a more efficient and labor-saving working experience.

[0047] It should be noted that, to improve connection stability, the diameter of the pin 204 should be equal to the diameters of the through hole 203 and the locking hole 205. Alternatively, the diameters of the pin 204 and the through hole 203 should have a small clearance fit, and the diameters of the through hole 203 and the locking hole 205 should be equal. This ensures that the pin 204 is firmly and reliably inserted, preventing the support structure from becoming unbalanced due to loosening. Simultaneously, the spacing of the locking holes 205 should be reasonably set according to actual usage requirements, typically 5-10 cm, to allow for precise adjustment at different heights. Alternatively, an anti-slip threaded structure can be provided on the pin 204, with the through hole 203 and the locking hole 205 also forming a threaded connection, thereby improving connection stability.

[0048] For ease of movement, in this embodiment, a universal caster 5 is provided at the bottom of the movable rod 202.

[0049] As a further improvement of this utility model, two retractable support legs 200 are provided, symmetrically arranged on both sides of the bottom of the pesticide tank 1. The symmetrical arrangement of the retractable support legs 200 on both sides effectively improves the support stability of the pesticide tank 1, ensuring the overall balance and safety of the device during application. When operating on complex terrain or slopes, the two support legs can be independently adjusted according to ground undulations, keeping the pesticide tank 1 level and preventing pesticide spillage or uneven spraying due to tilting. Simultaneously, the symmetrically arranged support leg structure effectively distributes the weight of the pesticide tank 1, reducing pressure on one side and extending the device's service life. This design not only improves the convenience and adaptability of pesticide application but also further ensures the safety and reliability of field operations, providing excellent support for the practicality and efficiency of agricultural pesticide application equipment.

[0050] Of course, to improve the stability of the device, two swivel casters 5 are also installed at the two other corners of the bottom of the medicine tank 1. When the movable rod 202 is retracted to its deepest point inside the fixed tube 201, the four swivel casters 5 are located on the same horizontal plane. By installing swivel casters 5 at the bottom of the movable rod 202, the medicine tank 1 can be pulled using the swivel casters 5 when the movable rod 202 is retracted, and the medicine tank 1 can also be dragged using the swivel casters 5 when the movable rod 202 is extended, making it convenient to move. The design of the swivel casters 5 effectively reduces the resistance when the sprayer moves in the field, making movement easier and more free. Especially on uneven field roads, the swivel casters 5 can turn flexibly, adapt to complex terrain, and reduce the physical exertion of the sprayer. In addition, the casters are made of wear-resistant and non-slip materials, with good corrosion resistance and durability, and can operate stably in wet and muddy environments, further improving the practicality and work efficiency of the device.

[0051] As a further improvement of this utility model, the spray gun 3 is provided with a plurality of nozzles 31, all of which are arranged sequentially at intervals along the axial direction of the spray gun 3. By setting multiple nozzles 31 and arranging them at intervals along the axial direction, the pesticide solution can form a uniform atomization effect during spraying, covering a wider area and improving the uniformity of application and work efficiency. The layout of multiple nozzles 31 can effectively avoid spraying blind spots, ensuring that the pesticide fully covers the crop surface and improving the control effect. At the same time, the axial spacing can reduce mutual interference between nozzles 31, reduce the phenomenon of pesticide collision and backflow, thereby improving spraying stability.

[0052] As a further improvement of this utility model, the spray gun 3 is fitted with a detachable gun sleeve 9, which is made of plastic. By providing the gun sleeve 9, it can be removed during use and sealed with the cover 11 when stored to prevent liquid dripping, while maintaining the cleanliness of the equipment and preventing residual liquid from polluting the environment. Furthermore, the gun sleeve 9 is made of lightweight plastic, combining durability and portability, making it easy for users to quickly disassemble and clean.

[0053] As a further improvement of this utility model, a filter screen 100 is provided inside the medicine tank 1 to prevent impurities from clogging the nozzles and improve the service life of the equipment. The filter screen 100 is located at the liquid outlet of the medicine tank 1 and can effectively intercept solid impurities and undissolved particles in the liquid, preventing the nozzles from being clogged and affecting the spraying effect. The filter screen 100 adopts a multi-layer structure design, possessing high filtration accuracy and permeability, while also being easy to disassemble, clean, or replace, ensuring that the equipment maintains a good working condition during long-term use. Furthermore, the presence of the filter screen 100 reduces the frequency of equipment maintenance, improves the continuity and efficiency of pesticide application, and provides more stable and reliable support for field management.

[0054] As a further improvement of this utility model, the filter screen 100 is detachable, facilitating cleaning and replacement and ensuring smooth flow of pesticide solution. The device has a simple overall structure and is easy to operate, suitable for pest and disease control of various crops, and possesses strong practicality and promotional value. By adopting the detachable filter screen 100 design, users can quickly clean or replace it without the need for specialized tools, significantly reducing the difficulty and time cost of equipment maintenance. At the same time, this structural design fully considers the applicability of different pesticide components, effectively preventing impurities from accumulating and obstructing flow even when using high-concentration or residue-prone pesticides. This convenient and optimized filtration system design provides a strong guarantee for the efficient and stable operation of the portable insecticide device, while also extending the overall service life of the equipment, making it suitable for pesticide application needs in various complex farmland environments.

[0055] Specifically, the medicine box 1 has a medicine inlet at the top, and a cover 11 at the medicine inlet. A buckle is located on the side of the bottom of the medicine box 1 corresponding to the liquid outlet. The filter screen 100 includes a frame and a filter screen disposed within the frame. A slot 101 adapted to the buckle is provided on the frame, and the buckle and slot 101 engage in a snap-fit ​​connection. Of course, the buckle and slot 101 structure can be implemented using existing technology, as long as the snap-fit ​​connection is achieved. Other snap-fit ​​structures are also possible, not limited to the buckle and slot 101 structure.

[0056] To improve the protection level of pesticide application personnel, this embodiment also includes a support frame 6, a ring frame 7, and a protective cover 8; wherein:

[0057] Support 6 is a portal frame structure and is installed on top of medicine box 1;

[0058] The ring frame 7 is a circular structure, horizontally positioned above the human head, and connected to the support frame 6;

[0059] The protective cover 8 is similar to a shower curtain structure and is made of transparent film or plastic; the top has a sleeve part 81, which is fitted onto the ring frame 7, and both ends of the protective cover 8 can be pulled open or retracted along the extension direction of the ring frame 7.

[0060] Specifically, when protection is needed, the two ends of the protective cover 8 can be pulled close to each other and then overlapped with the front end of the ring frame 7, thus achieving overall protection for the human head. Furthermore, the use of transparent material allows the outside to be seen without affecting the application of medicine. When protection is not needed, the protective cover 8 can be opened and pulled to the back to overlap.

[0061] The protective cover 8 can slide and adjust its position along the ring frame 7, similar to a shower curtain structure. The diameter of the enclosure can be adjusted according to the user's situation to prevent the sprayed liquid from entering the face, mouth or nose of the sprayer, thereby effectively protecting the health and safety of the sprayer.

[0062] Finally, it should be noted that... Figure 1 The protective shield 8 was removed to facilitate understanding of its structural composition. The pressurization device is not shown in the attached diagram because it is existing technology and has not been improved. Additionally... Figure 1 The retractable support leg 200 is not shown in the attached diagram. To facilitate the disassembly, cleaning, and replacement of the protective cover 8, the sleeve part 81 has two Velcro straps 8 / 2 on the top of the protective cover 8, which are fastened together using Velcro straps 82 to form the sleeve part 81. Furthermore, the attached diagram is only a structural illustration and does not represent normal proportional relationships. The material selection, diameter, wall thickness, and other parameters of the support legs and support frame should be designed according to actual conditions to reduce weight while ensuring strength. The diameter of the filter screen 100 is smaller than the diameter of the dosing port to facilitate the removal or insertion of the filter screen 100 through the dosing port.
