Description

Technical Field

[0001] This invention relates to the field of crop pest and disease control technology, and in particular to pesticide delivery machines. Background Technology

[0002] Crop diseases and pests are one of the major agricultural disasters. They are characterized by their variety, significant impact, and frequent outbreaks that can cause major losses to the national economy, especially agricultural production, due to their wide range and severity.

[0003] When crops are affected by pests and diseases, the conventional method is to spray pesticides to control them. However, when spraying pesticides, most of the pesticides are applied to the surface of the crops. For some diseases inside the plant, conventional spraying devices cannot allow the pesticides to penetrate into the plant, resulting in poor effectiveness.

[0004] Therefore, there is an urgent need for a pesticide dispensing machine to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a pesticide spraying machine that can spray pesticides into the inside of plant stems, thereby improving the effectiveness of pesticide spraying and ensuring that plants are protected from pests and diseases during the planting process.

[0006] To achieve this objective, the present invention adopts the following technical solution:

Each spraying assembly includes a second driving mechanism and a spraying structure. The two second driving mechanisms drive the two spraying structures respectively, causing the two spraying structures to move closer to or further away from each other. When the two needle structures and the two spraying structures are far apart, it is easy to move the insertion device and the spraying device to avoid damage to the plant. When the two needle structures are close together, they can make holes in the plant stem, which makes it easier for the two spraying structures to approach each other to spray pesticides on the stem after the holes are made. This ensures that the pesticide can enter the plant stem through the holes, thereby improving the spraying effect of the pesticide. Attached Figure Description

[0037] like Figures 1 to 4As shown, this embodiment provides a pesticide spraying machine for spraying pesticides into the stems of plants to ensure that the stems are protected from pests and diseases. The pesticide spraying machine includes an insertion device 10 and a spraying device 20. The insertion device 10 includes a first support frame 11 and two sets of needle assemblies. The first support frame 11 includes two first support arms 111, and the two sets of needle assemblies are respectively disposed on the two first support arms 111. Each needle assembly includes a first drive mechanism and a needle structure 13. The first drive mechanism is disposed on the first support arm 111, and the needle structure 13 is slidably disposed on the first support arm 111 along a first direction. The first drive mechanism is connected to the needle structure 13 in a transmission manner. The two needle structures 13 are arranged opposite to each other, and the two first drive mechanisms can drive the two needle structures 13 respectively, thereby causing the two needle structures 13 to move closer or further apart, thus spraying pesticides into the plant stems. The spraying device 20 is connected to the insertion device 10. The spraying device 20 includes a second support frame 21 and two sets of spraying components. The second support frame 21 includes two second support arms 211. The two sets of spraying components are respectively disposed on the two second support arms 211. Each spraying component includes a second drive mechanism and a spraying structure 23. The second drive mechanism is disposed on the second support arm 211. The spraying structure 23 is slidably disposed on the second support arm 211 along a first direction. The second drive mechanism and the spraying structure 23 are connected by transmission. The two spraying structures 23 are disposed opposite to each other. The two second drive mechanisms can drive the two spraying structures 23 respectively, thereby making the two spraying structures 23 approach or move away from each other to spray pesticide on the stems of the plant.

[0038] Specifically, in this embodiment, as Figure 2 and Figure 4As shown, the first support frame 11 includes two first support arms 111, and two sets of pin assemblies are respectively disposed on the two first support arms 111. The pin assembly includes a first drive mechanism and a pin structure 13. The first support arms 111 can provide support for the first drive mechanism and the pin structure 13, so that the first drive mechanism is installed stably. The pin structure 13 is slidably disposed on the first support arm 111 along the first direction, and the two pin structures 13 are disposed opposite to each other. When the two first drive mechanisms drive the two pin structures 13 to move along the first direction, the two pin structures 13 can move closer to each other or further away from each other. When the two pin structures 13 move away from each other, the pin structures 13 are away from the plant, which facilitates the movement of the insertion device 10 and avoids damage to the plant when the insertion device 10 moves. When the two pin structures 13 move closer to each other, the pin structures 13 are close to the plant, which can insert holes into the stem of the plant and ensure the normal use of the insertion device. The second support frame 21 includes two The second support arm 211 has two spraying components respectively mounted on it. Each spraying component includes a second drive mechanism and a spraying structure 23. The second support arm 211 provides support for the second drive mechanism and the spraying structure 23, ensuring stable installation of the second drive mechanism. The spraying structure 23 is slidably mounted on the second support arm 211 along a first direction, and the two spraying structures 23 are positioned opposite each other. When the two second drive mechanisms drive the two spraying structures 23 to move along the first direction, the two spraying structures 23 can move closer to or further away from each other. When the two spraying structures 23 move further away from each other, they are further away from the plant, facilitating the movement of the spraying device 20 and preventing damage to the plant during the movement of the spraying device 20. When the two spraying structures 23 move closer to each other, they are closer to the plant, ensuring the effectiveness of the sprayed pesticide and avoiding pesticide waste.

[0039] Optionally, in this embodiment, along the forward direction of the pesticide delivery machine, the spraying device 20 is located behind the insertion device 10, and the plant is first inserted into the hole before the pesticide is sprayed onto the plant.

[0040] Furthermore, the first driving mechanism includes a first driving motor 12 and a first gear 121. The first driving motor 12 is fixedly connected to the first support frame 11, and the first gear 121 is disposed at the output end of the first driving motor 12. The pin insertion structure 13 includes a first guide ring 131, a first slide rod 132, and a pin head 133. The first guide ring 131 is fixedly disposed on the first support frame 11, and the first slide rod 132 and the pin head 133 are fixedly connected. The first slide rod 132 is slidably disposed on the first guide ring 131 along a first direction. The outer periphery of the first slide rod 132 is provided with teeth, so that the first slide rod 132 can be connected to the first gear 121 for transmission. The first driving motor 12 drives the first gear 121 to rotate, causing the first slide rod 132 to slide along the first guide ring 131, thereby causing the two pin heads 133 to approach or move towards each other along the first direction. The second drive mechanism includes a second drive motor 22 and a second gear 221. The second drive motor 22 is fixedly connected to the second support frame 21, and the second gear 221 is located at the output end of the second drive motor 22. The spraying structure 23 includes a second guide ring 231, a second slide rod 232, and a spray head 233. The second guide ring 231 is fixedly located on the second support frame 21, and the second slide rod 232 and the spray head 233 are fixedly connected. The second slide rod 232 is slidably located on the second guide ring 231 along the first direction. The outer circumference of the second slide rod 232 is provided with teeth so that the second slide rod 232 can be connected to the second gear 221 for transmission. The second drive motor 22 drives the second gear 221 to rotate, so that the second slide rod 232 slides along the second guide ring 231, thereby causing the two spray heads 233 to move closer to or further away from each other along the first direction.

[0041] Specifically, in this embodiment, the two first support arms 111 of the first support frame 11 are arranged parallel and spaced apart. The pin structure 13 includes a first guide ring 131, a first slide rod 132, and a pin head 133. The first guide ring 131 is fixedly disposed on each of the two first support arms 111. The first guide ring 131 has a first guide hole extending in a first direction. The first slide rod 132 is slidably disposed in the first guide hole. The two pin heads 133 are located on the inner side of the two first support arms 111. The side of the first slide rod 132 away from the pin head 133 is provided with teeth. The first drive motor 12 is fixedly disposed on the outer side of the first support arm 111 through the first fixing frame 122. The output end of the first drive motor 12 is connected to the first gear 121 for transmission. The first gear 121 is connected to the teeth of the first slide rod 132 for transmission. When the first drive motor 12 drives the first gear 121 to rotate, the first slide rod 132 can slide along the first guide hole, thereby ensuring that the two pin heads 133 can move closer or further away from each other, so as to perform plant treatment. The second support frame 21 has two parallel and spaced-apart second support arms 211. The spraying structure 23 includes a second guide ring 231, a second slide rod 232, and a spray head 233. A second guide ring 231 is fixedly mounted on each of the two second support arms 211. A second guide hole extending in a first direction is provided on the second guide ring 231. The second slide rod 232 is slidably disposed in the second guide hole. The two spray heads 233 are located inside the two second support arms 211, and the second slide rod 232 is away from the spray head. One side of the 233 is provided with teeth. The second drive motor 22 is fixedly mounted on the outside of the second support arm 211 through the second fixing bracket 222. The output end of the second drive motor 22 is connected to the second gear 221 for transmission. The second gear 221 is connected to the second slide rod 232 for transmission. When the second drive motor 22 drives the second gear 221 to rotate, the second slide rod 232 can slide along the second guide hole, thereby ensuring that the two spray heads 233 can approach or move away from each other to spray pesticides on the plants.

[0042] Alternatively, in other embodiments, the first drive mechanism may be other structures that enable the two pin structures 13 to move closer to each other or further away from each other, such as a linear cylinder. Similarly, the second drive mechanism may also be other structures that enable the two spray structures 23 to move closer to each other or further away from each other, which will not be elaborated here.

[0043] Furthermore, the needle head 133 includes a fixing member 1331 and needles 1332. The fixing member 1331 is fixedly connected to the first slide bar 132, and multiple needles 1332 are evenly distributed on the side of the fixing member 1331 away from the first slide bar 132. Specifically, in this embodiment, the fixing member 1331 and the first slide bar 132 can be connected by welding, or the fixing member 1331 and the first slide bar 132 can be integrally formed. There is no limitation here. The multiple needles 1332 being evenly distributed on the side of the fixing member 1331 away from the first slide bar 132 can ensure normal insertion into the plant and also ensure the uniformity of the insertion holes, thereby improving the effectiveness of drug spraying.

[0044] Furthermore, the fixing member 1331 is arc-shaped, and two fixing members 1331 are interlocked. The area formed by the two fixing members 1331 is used to accommodate the plant stem. Specifically, in this embodiment, both fixing members 1331 are semi-circular, and the needle 1332 is perpendicularly arranged along the normal of the arc on the inner side of the fixing member 1331. This arrangement allows the plant to be inserted from all sides, improving the effectiveness of pesticide spraying and preventing the needle 1332 from damaging the plant stem.

[0045] Furthermore, the spray head 233 is arc-shaped, and two spray heads 233 are interlocked, with the area formed by the two spray heads 233 used to accommodate the plant stem. Specifically, in this embodiment, both spray heads 233 are semi-circular, and spray holes are provided on the spray heads 233. This arrangement allows the plant to be sprayed with the pesticide from all sides, improving the uniformity and effectiveness of the pesticide spraying and enhancing the spraying effect.

[0046] Furthermore, the insertion device 10 also includes a first walking structure 14 and a first adjusting structure 15, with two of each. The two first adjusting structures 15 are respectively disposed between the two first walking structures 14 and the two first support arms 111. The first walking structure 14 is used to walk along the ground, and the first adjusting structure 15 is used to adjust the height of the insertion structure 13 from the ground. The spraying device 20 also includes a second walking structure 24 and a second adjusting structure 25, with two of each. The two second adjusting structures 25 are respectively disposed between the two second walking structures 24 and the two second support frames 21. The second walking structure 24 is used to walk along the ground, and the second adjusting structure 25 is used to adjust the height of the spraying structure 23 from the ground.

[0047] Specifically, in this embodiment, the insertion device 10 includes two first walking structures 14 and two first adjusting structures 15. The two first walking structures 14 are respectively connected to two first support arms 111 via the two first adjusting structures 15. The two first walking structures 14 are used for walking, allowing the insertion device 10 to move smoothly on the ground. The two first adjusting structures 15 are used to adjust the height of the first support frame 11 from the ground, thereby adjusting the height of the two insertion structures mounted on the first support frame 11 from the ground. This allows the insertion needle structure 13 to easily adjust the position and height of the insertion hole when inserting into the plant, and ensures that insertion holes can be made at various positions on the plant stem, improving efficiency. The device includes two second walking structures 24 and two second adjusting structures 25. The two second walking structures 24 are connected to two second support arms 211 respectively through the two second adjusting structures 25. The two second walking structures 24 are used for walking, so that the spraying device 20 can walk smoothly on the ground. The two second adjusting structures 25 are used to adjust the height of the two second support arms 211 relative to the ground, thereby adjusting the height of the two spraying structures 23 installed on the second support frame 21 relative to the ground. This allows the spraying structures 23 to easily adjust the spraying height when spraying pesticides on plants, thus ensuring that the entire plant can be sprayed with pesticides and improving the effect of pesticide spraying.

[0048] Furthermore, the first walking structure 14 includes a first base plate 141, a first connecting member 142, and a first roller assembly 143. The first roller assembly 143 is installed at the bottom of the first base plate 141, and the first connecting member 142 is connected to the first support arm 111 through a first adjusting structure 15. The second walking structure 24 includes a second base plate 241, a second connecting member 242, and a second roller assembly 243. The second roller assembly 243 is installed at the bottom of the second base plate 241, and the second connecting member 242 is connected to the second support arm 211 through a second adjusting structure 25. Specifically, in this embodiment, the first roller assembly 143 is installed at the bottom of the first base plate 141, which facilitates the movement of the first base plate 141. The second roller assembly 243 is installed at the bottom of the second base plate 241, which also facilitates the movement of the second base plate 241. In actual use, the roller assembly can reduce friction with the ground, making the movement of the insertion device 10 and the spraying device 20 easier and reducing the workload of personnel.

[0049] Furthermore, such as Figure 3As shown, the first adjustment structure 15 includes a first telescopic member 151 and a first sliding member 152. One end of the first sliding member 152 is fixedly connected to the first connecting member 142, and the other end of the first sliding member 152 is slidably disposed on the first support arm 111 along the second direction. The fixed end of the first telescopic member 151 is fixedly disposed on one end of the first sliding member 152 connected to the first connecting member 142, and the movable end of the first telescopic member 151 is connected to the first support arm 111. When the first telescopic member 151 extends or retracts, it can drive the first sliding member 152 to slide along the first support arm 111, thereby adjusting the first support arm 111. 11. Height of the second support frame 21 relative to the ground; The second adjustment structure 25 includes a second telescopic member 251 and a second sliding member 252. One end of the second sliding member 252 is fixedly connected to the second connecting member 242, and the other end of the second sliding member 252 is slidably disposed on the second support arm 211 along the second direction. The fixed end of the second telescopic member 251 is fixedly disposed on the second connecting member 242, and the movable end of the second telescopic member 251 is connected to the second support arm 211. When the second telescopic member 251 extends or retracts, it can drive the second sliding member 252 to slide along the second support arm 211, thereby adjusting the height of the second support frame 21 relative to the ground.

[0050] Specifically, in this embodiment, the first adjustment structure 15 and the second adjustment structure 25 have the same specific structure. The first adjustment structure 15 includes a first telescopic member 151 and a first sliding member 152. A first groove 1111 is provided on the first support arm 111. A first slider 1521 is provided at one end of the first sliding member 152. The first slider 1521 is slidably disposed in the first groove 1111. The other end of the first sliding member 152 is fixedly connected to the first connecting member 142.
