They should not be understood as limitations of the present invention.

[0031] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0032] like Figure 1-6 As shown, this embodiment proposes a directional spraying device for sweet potato fields, which includes a vehicle body 1, a medicine tank 2 is provided on the vehicle body 1, and the medicine tank 2 is connected to a medicine pump 3. Two guide frames 4 are also provided on the vehicle body 1, and a spraying arm 5 that can slide up and down is provided in the guide frame 4. The spraying arm 5 is provided with several groups of nozzles 57, and the nozzles 57 are connected to the medicine pump 3. The spraying arm 5 is rotatably arranged in the guide frame 4, and a pressure plate 7 is fixedly connected above the spraying arm 5. The pressure plate 7 is arranged to be inclined upward, and also includes a lifting rod 8. A pressure plate 9 is provided on the top of the lifting rod 8. The pressure plate 9 is used to press the two pressure plates 7 downward to change the spraying arm 5 from a vertical state to a horizontal state.

[0033] When not in use, the spray arm 5 is placed in a vertical state in the guide frame 4, and the guide frame 4 provides a certain protection for the spray arm 5. When spraying is needed, the telescopic rod is lowered to drive the pressure plate 9 to press the pressure plate 7. The spray arm 5 rotates in the guide frame 4 under the downward pressure, and changes from a vertical state to a horizontal state. At this time, the medicine pump 3 transports the liquid medicine in the medicine tank 2 to the nozzle 57 under the spray arm 5, and the nozzle 57 sprays the sweet potato in a direction. Compared with the spray device with horizontal support arms in the prior art, this design can save more space. It can be folded and stored when not in use, especially for household sprayers. The width of the door is limited, and the longer support arms are difficult to enter the home for storage. The folded spray arm 5 is convenient for transportation to avoid traffic hazards caused by excessive space occupation during transportation.

[0034] In some embodiments, the spray arm 5 includes a first arm 51 and a second arm 52. The first arm 51 and the second arm 52 are foldable or extendable, and the aforementioned groups of nozzles 57 are located outside the first arm 51 and the second arm 52. By folding the first arm 51 and the second arm 52, the overall length of the spray arm 5 is extended without occupying additional space, allowing the vehicle 1 to spray more areas during a single movement. For example, in some cases, if drug delivery is required to the side of sweet potatoes, the drug delivery pump 3 can be used to input the drug solution into the nozzles 57 in the lower half of the second arm 52, thereby completing the side delivery.

[0035] like Figures 4 and 5As shown, in some embodiments, a tray 53 for supporting the second arm 52 is fixedly connected to the bottom of the first arm 51 in the spray arm 5, and the tray is U-shaped. A folding plate 54 is hinged between the tray 53 and the second arm 52. Specifically, an axle rod is fixed on both the tray 53 and the folding plate 54, and both ends of the folding plate 54 are hinged to the axle rod; when the first arm 51 and the second arm 52 are in a folded state, the two arms are in a vertical state, and the folding plate 54 is in a horizontal state and placed between the two arms. When the first arm 51 and the second arm 52 are unfolded, the first arm 51 gradually rotates to become a horizontal state, and the tray 53 supports the second arm 52 to unfold it, and supports it so that the second arm 52 finally remains in a horizontal state. At this time, several groups of nozzles 57 are all at the bottom, and the sweet potato fields below the two arms are subjected to targeted drug administration.

[0036] In some embodiments, the guide frame 4 includes guide rails opened on both sides, and a sliding member 6 is commonly connected between the two guide rails. The above-mentioned spray arm 5 can be rotatably placed in the sliding member 6. Through holes 10 are opened on both sides of the guide frame 4 and the sliding member 6, and a threaded pin 11 can be inserted into the through hole 10 to fix the sliding member 6; further, a through hole 12 is opened on the vehicle body 1, and the through hole 12 is located below the spray arm 5; the height of the spray arm 5 on the ground is adjusted by the sliding member 6, and the sliding member 6 is placed between the two guide rails and slides. After sliding to the designed height, the threaded pin 11 is inserted into the through hole 10 to achieve the adjustment of the current height of the spray arm 5, and the sliding member 6 can also be threadedly connected to the threaded pin 11 by a nut to achieve a more stable fixation of the sliding member 6. The through hole 12 on the vehicle body 1 can be used for the bottom of the spray arm 5 to pass through, and the nozzle 57 in the bottom area of the second arm 52 is used to achieve side medication near the root of the sweet potato.

[0037] like Figure 3 As shown, in some embodiments, the slider 6 includes two wings positioned within the guide rails, with through holes 10 formed in the wings. A hanger plate 61 is fixedly connected between the wings. The hanger plate 61 has an inverted U-shape and a rotating shaft 62 is disposed within the hanger plate 61. The spray arm 5 is hingedly connected to the rotating shaft 62 to enable rotation. In this design, the wings allow for height adjustment. After adjustment, the inverted U-shaped hanger plate 61 provides more room for the spray arm 5 to move, allowing the spray arm 5 to gradually rotate to a horizontal position.

[0038] In some embodiments, an input port 55 is provided on both the first arm 51 and the second arm 52, and an output port 56 is also provided on the first arm 51. The output port 56 of the first arm 51 can be connected to the input port 55 on the second arm 52, and the drug pump 3 can be connected to any input port 55 to transport the drug solution; during use, it can be selected according to actual conditions. If upper drug administration is selected, the output port 56 of the first arm 51 is connected to the input port 55 of the second arm 52 through a pipeline, and the drug pump 3 is connected to the input port 55 of the first arm 51, so that the nozzles 57 on the two arms can be used to administer the drug from above; if side drug administration is selected, the drug pump 3 can be directly connected to the input port 55 on the second arm 52 through a pipeline, and only the nozzle 57 on the second arm 52 is connected to the drug pump 3, thereby realizing side drug administration.

[0039] In some embodiments, a feed port 13 is provided on the medicine tank 2, and a stirring motor 14 is also provided on the medicine tank 2. The stirring motor 14 is connected to a stirring rod, and the stirring rod is placed inside the medicine tank 2 to stir the internal medicine liquid. The medicine to be used is filled into the medicine tank 2 through the feed port 13. During the spraying process, in order to prevent the medicine in the medicine liquid from precipitating downward, the medicine liquid is continuously stirred by the stirring rod to keep it in the best state to improve the application effect.

[0040] In some embodiments, a storage box 15 is provided on the vehicle body 1, and the above-mentioned lifting rod 8 is provided above the storage box 15. The storage box 15 can be used to place medicines. In some cases, the concentration can be adjusted on-site with the medicine liquid in the medicine tank 2. It can also be used to place commonly used small tools, etc.; on the other hand, the lifting rod 8 is raised by the storage box 15 to reduce the stroke of the lifting rod 8. Using a lifting rod 8 with a shorter stroke can reduce certain costs.

[0041] In some embodiments, a total of four sets of wheels are detachably provided under the vehicle body 1, and the existing disassembly and installation method is adopted to realize the replacement of wheel size, which is used to raise the entire vehicle body. When the sweet potato vines grow to a certain state, by replacing larger wheels, damage to the sweet potato vines under the vehicle body 1 during travel is avoided. At this time, the bottom of the vertical first arm 51 and the second arm 52 pass through the through-hole 12 to apply pesticides to the roots of the sweet potato vines.

[0042] It is worth noting that the first arm 51 and the second arm 52 can adopt a hollow plate structure or a truss structure to reduce the weight of both; wherein, the nozzles 57 on the first arm 51 and the second arm 52 adopt nozzles 57 whose switches can be manually controlled, and the nozzles 57 on the second arm 52 are convenient for closing the uppermost nozzle 57 when administering medicine on the side, and only administering medicine on the root and rhizome below to avoid waste; in some cases, it is necessary to spray herbicides in the ditch, and only the nozzle 57 above the ditch on the extended first arm 51 is opened, and the nozzle 57 is sprayed directly into the ditch to achieve directional spraying in the ditch.

[0043] The spraying method of this device is as follows:

[0044] In the initial state, the spraying arm 5 is in a vertical state and is located in the guide frame 4 for easy storage: when in use, the liquid medicine is added to the medicine tank 2 through the feed port 13, the vehicle body 1 is moved to the area to be sprayed by manpower or other power vehicles, the lifting rod 8 is started, and the pressure plate 9 on the lifting rod 8 is moved down and the pressure plate 9 is pressed down, so that the spraying arm 5 is gradually rotated from the vertical state to the horizontal state. At the same time as the first arm 51 is unfolded, the tray 53 lifts the second arm 52 assembly hinged thereto to unfold, and then according to the growth status of the sweet potato seedlings, the second arm 52 assembly is lifted and the second arm 52 assembly is lifted and the second arm 52 assembly is opened. Adjust the distance between the slider 6 and the ground to a suitable height, insert the threaded pin 11 into the through hole 10 to fix the slider 6 and the spray arm 5 at the current height in the guide frame 4, and then start the medicine pump 3. The medicine pump 3 transports the liquid medicine to the nozzle 57 of the spray arm 5. As the vehicle body 1 moves, the current area is sprayed with medicine. During the movement of the vehicle body 1, the stirring motor 14 drives the stirring rod to rotate to fully mix the liquid medicine in the medicine tank 2, so as to keep the liquid medicine in the best mixed state and transport it to the nozzle 57.

[0045] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
