As the core equipment of the trials, the performance of the spraying device directly affects the accuracy and reliability of the test data.

[0003] Currently, traditional field pesticide spraying devices generally have the following problems when conducting multiple efficacy comparison tests: most devices have a shared structure for pesticide delivery pipelines. When switching between different reagents, it is difficult to completely remove the residue of the previous pesticide in the pipeline, which is easy to mix with the next pesticide, resulting in cross-contamination between test groups and distorting the comparison results.

The bottle mouths pass through the tray and are connected to caps. The bottom of the caps is connected to a delivery pipe, which is connected to the reagent bottles. A pipe connector is connected at one end to the spray bar and at the other end to the delivery pipe. A pump body is connected to the delivery pipe to deliver the reagents to the pipe connector. A water tank is placed inside the box body and has a water pump inside. The output end of the water pump is connected to a water pipe, and the other end of the water pipe is connected to the pipe connector.

[0007] Preferably, the conveying tray has a perforation for the mouth of the reagent bottle to pass through, and a support is connected above the tray. The support has an inverted frustum-shaped lifting cavity inside, and the lifting cavity is connected to the perforation.

[0008] Preferably, a positioning element for positioning the bottom of the reagent bottle is provided on the top of the box, and a placement space for positioning the reagent bottle is formed between the positioning element and the support.

[0009] Preferably, the positioning component includes a threaded cylinder with jaws distributed circumferentially below the threaded cylinder. The jaws have a radially outward-inclined structure, and a nut is threadedly connected to the threaded cylinder to compress the jaws downward, causing the jaws to elastically deform and converge towards the center, thereby clamping the bottom of the reagent bottle.

[0010] Preferably, the bottom of the gripper is provided with an inwardly protruding part, and the protruding part is made of rubber.

[0011] Preferably, the box body has several sets of through holes arranged in a vertical array on both sides, and the tray has threaded holes on both sides; it also includes bolts, which pass through the corresponding through holes and are threadedly connected to the threaded holes to position the tray at a preset height inside the box.

[0012] Preferably, the reagent bottle mouth and the cap are connected by a detachable threaded connection; a rubber stopper is fixed inside the reagent bottle mouth, and a puncture tube that can pierce the rubber stopper and be placed inside the reagent bottle is fixed inside the cap, and the puncture tube is connected to the delivery tube.

[0013] Preferably, a one-way valve is provided at the connection point between the delivery pipe and the water supply pipe and the pipe joint.

[0014] Preferably, a control panel is provided on one side of the housing, and the control panel is provided with control buttons for controlling the pump body and water pump start and stop; a power supply is also provided inside the housing, and the power supply is electrically connected to the control panel, pump body and water pump.

[0015] Preferably, the water tank is connected to a water inlet pipe at the top, and the water inlet end of the water inlet pipe is located outside the tank and is detachably equipped with a switch cover.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] 1. In this utility model, different reagent bottles are set inside the box and connected to the pipe joints through independent delivery pipes to form independent delivery paths, which prevents the mixing of different reagents due to sharing pipes during delivery. It is also equipped with a water tank and water pump to flush the pipe joints and spraying rods, and to flush and discharge any residual previous reagents. This solves the problem of residual reagents in the pipes affecting the next set of experiments in traditional devices, enabling continuous comparative experiments of different reagents.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments.

[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figure 1 or Figure 5 As shown, this embodiment proposes a spraying device for comparing the efficacy of pesticides in the field. It includes a housing 1, with a spray bar 2 mounted on one side of the housing 1. The spray bar 2 is connected to the side of the housing 1 via a flexible hose. It also includes at least two sets of reagent bottles 3, containing different reagents for comparative testing. The reagent bottles 3 are placed upside down inside the housing 1 using a support plate 4. The bottle opening passes through the support plate 4 and is connected to a cap 6. The bottom of the cap 6 is connected to a delivery pipe 7, which is connected to the reagent bottle 3. It also includes a pipe connector 8, one end of which is connected to the spray bar 2, and the other end to the delivery pipe 7. A pump 9 connected to the delivery pipe 7 transports the reagent from the delivery pipe 7 to the pipe connector 8, from which it is sprayed out. A water tank 10 is also located at the bottom of the housing 1. A water pump 11 is installed inside the water tank 10. The output end of the water pump 11 is connected to a water delivery pipe, the other end of which is connected to the pipe connector 8.

[0036] The front of the box 1 is equipped with two sets of shoulder straps, which can be used to carry the box 1 for easy transfer and operation in various test areas. The rear of the box 1 is equipped with a detachable maintenance door 17, through which internal components can be inspected or reagent bottles 3 can be replaced.

[0037] In this design, different reagent bottles 3 are connected to pipe joints 8 via independent delivery pipes 7, forming an independent delivery path for each reagent bottle and pipe. This prevents the mixing of different reagents during delivery due to shared pipes, ensuring that each reagent remains pure during its flow from the reagent bottle 3 to the spray bar 2. This ensures that the composition of the pesticide sprayed in the field is completely consistent with the experimental design, providing reliable basic data for efficacy comparison and avoiding distortion of experimental results due to cross-contamination.

[0038] Furthermore, the flushing system, consisting of water tank 10 and water pump 11, can deliver clean water to the pipe joint 8 and spray nozzle 2 when changing reagents, flushing and draining any residual previous agent. This solves the problem of residual agent affecting the next set of experiments in traditional devices, enabling continuous comparative experiments with different reagents and improving overall experimental efficiency. On the other hand, the device adopts a modular design with a housing 1, independent reagent bottles 3, and corresponding delivery pipes 7. The number or type of reagent bottles 3 can be adjusted according to application needs, accommodating comparative scenarios with different pesticide types and concentrations. It also facilitates quick replacement of reagent bottles 3, meeting diverse experimental design requirements.

[0039] In some embodiments, the conveying tray 4 has several sets of perforations for the mouth of the reagent bottle 3 to pass through. A support 41 is connected to the tray 4. The support 41 has an annular structure and forms an inverted frustum-shaped lifting cavity 42 inside, which is connected to the perforations. After the mouth of the bottle passes through the tray 4, the support 41 can fit against the upper part of the reagent bottle 3 to form a preliminary positioning.

[0040] In some embodiments, a positioning member 5 for positioning the bottom of the reagent bottle 3 is provided above the housing 1. The positioning member 5 and the support 41 can form a placement space for positioning the reagent bottle 3, and the reagent bottle 3 is positioned inside it.

[0041] Further reference Figure 4 The positioning component 5 includes a threaded cylinder 51 fixed to the lower part of the top wall of the housing 1. Grippers 52 are circumferentially distributed below the threaded cylinder 51, and the grippers 52 have a radially outwardly inclined structure. A nut 53 is threaded onto the threaded cylinder 51 to compress the grippers 52 downwards. By rotating the nut 53 to engage with the threaded cylinder 51, it moves downwards, compressing the outside of the grippers 52 during this downward movement, causing the grippers 52 to elastically deform and converge towards the center, thereby clamping the bottom of the reagent bottle 3. An inwardly protruding protrusion 54, made of rubber, is provided at the bottom of the clamping column.

[0042] During the installation of reagent bottle 3, invert reagent bottle 3 so that its bottom is placed between the clamps and the bottle mouth passes through the support plate 4, so that the upper half of the bottle is placed on the support 41. Then, screw on the nut 53. The nut 53 drives the clamps 52 to close and clamp the bottom of the bottle, which can easily achieve the positioning of reagent bottle 3. The whole process does not require complicated tools, the operation steps are simple, and different reagent bottles 3 can be quickly loaded and unloaded.

[0043] In the above design, the support 41 fits against the upper half of the reagent bottle 3, providing initial radial constraint and preventing lateral swaying. The gripper 52 of the positioning component 5 clamps the bottle inwards, thus positioning the bottom of the reagent bottle 3 and securing it firmly inside the housing 1. This dual positioning method prevents the reagent bottle 3 from tipping over, even during field movement or spraying operations that generate vibration, ensuring stable transport and reducing the risk of reagent leakage due to bottle swaying.

[0044] The support 41 in this design has a frustum-shaped cavity inside that can accommodate the upper part of reagent bottles 3 of different diameters; the grippers 52 of the positioning member 5 can also be elastically deformed and retracted, and the clamping range can be flexibly adjusted according to the size of the bottom of the reagent bottle 3. Combined with the elastic buffer of the rubber protrusion 54, it can be compatible with reagent bottles 3 of various specifications and can meet the adaptability of diverse test needs.

[0045] refer to Figure 1 or Figure 2 In some embodiments, grooves are provided on both sides of the housing 1, and several sets of vertically arrayed through holes 101 are correspondingly provided in the grooves. Threaded holes 45 are provided on both sides of the tray 4. A bolt 13 is also included, which passes through the corresponding through hole 101 and is threaded into the threaded hole 45 to position the tray 4 at a preset height within the housing 1. In this design, the height of the tray 4 within the housing 1 is adjusted by positioning it with the bolt 13. By changing the distance between the tray 4 and the positioning element 5, the positioning space between the support 41 and the positioning element 5 can completely cover reagent bottles 3 of different heights, avoiding positioning loosening or installation problems caused by height mismatch, and significantly improving the device's compatibility with diverse reagent bottles 3.

[0046] In some embodiments, the mouth of the reagent bottle 3 and the cap 6 are connected by a detachable threaded connection. A rubber stopper 31 is fixed inside the mouth of the reagent bottle 3, and a puncture tube 12 that can puncture the rubber stopper 31 and be placed inside the reagent bottle 3 is fixed inside the cap 6. The puncture tube 12 is connected to the delivery tube 7.

[0047] refer to Figure 5 This design allows for the initial securing of reagent bottle 3 followed by the establishment of the delivery connection. Thanks to the sealing properties of the rubber stopper 31, even when reagent bottle 3 is inverted, internal reagent leakage is prevented. When the cap 6 is screwed on to connect with the bottle opening, the puncture tube 12 will naturally puncture the rubber stopper 31 and extend into the bottle, guiding the reagent into the delivery tube 7. When reagent bottle 3 needs to be replaced, simply unscrewing the cap 6 in the opposite direction allows the puncture tube 12 to be removed. At this point, the rubber stopper 31 will automatically close the puncture hole due to its elasticity, restoring the seal, allowing the operator to directly remove reagent bottle 3 from the tray 4. The entire replacement process requires no disassembly of complex tubing, making the operation simple and convenient, significantly reducing operational difficulty.

[0048] It is worth noting that the cap 6 and the delivery tube 7 are designed to rotate relative to each other. This design prevents the delivery tube 7 from twisting due to synchronous rotation with the cap 6 when the cap 6 is screwed on to connect with the bottle neck, ensuring that the pipeline always remains unobstructed.

[0049] In some embodiments, a one-way valve is provided at the connection points between the delivery pipe 7 and the water supply pipe and the pipe joint 8. The one-way valve can be any type, such as a spring-loaded one-way valve or a flap-type one-way valve. The one-way valve can further prevent liquid from entering the delivery pipe 7 during the cleaning process of the pipe joint 8.

[0050] In some embodiments, a control panel 102 is provided on one side of the housing 1, and the control panel 102 is provided with control buttons for controlling the start and stop of the pump body 9 and the water pump 11. A power supply 14 is also provided inside the housing 1, and the power supply 14 is electrically connected to the control panel 102, the pump body 9 and the water pump 11 to ensure normal operation.

[0051] In some embodiments, a water inlet pipe 15 is connected above the water tank 10. The water inlet end of the water inlet pipe 15 is located outside the tank body 1 and is detachably equipped with a switch cover 16. Clean water can be injected into the water tank 10 through the water inlet pipe 15 for subsequent flushing of the pipe joint 8 and the spray bar 2.

[0052] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
