[0053] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] The terms "first," "second," and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present invention can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, the term "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0055] The following is combined with Figure 1 To the attached Figure 6 , a crop cross-row spraying device provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0056] like Figure 1 As shown, an embodiment of the present invention provides a crop cross-row spraying device, which mainly includes five parts: a moving mechanism 100, a drug tube support 200, a liquid drug delivery mechanism 300, a drug supply mechanism 400, and a nozzle 500. Each part will be described in detail below:

[0057] The moving mechanism 100 is used to move along the gap between two adjacent crop planting ridges. The moving mechanism 100 is provided with a carrying plate 110;

[0058] In this embodiment, mobile mechanism 100 refers to a device capable of moving under the influence of a driving force, including but not limited to human power or power converted from various energy sources. Specifically, mobile mechanism 100 can be a flatbed truck, either currently available or potentially available in the future. Preferably, the height of mobile mechanism 100 can be set based on the height of the area where crops need to be sprayed. Specifically, when placed between ridges, the height of mobile mechanism 100 should be slightly lower than the lowest point in the area where crops need to be sprayed.

[0059] In this embodiment, crops include, but are not limited to, yams, corn, and similar crops. The width of the movable mechanism 100 can be set based on the gap between two adjacent rows of crops, typically being slightly smaller than that gap. For example, assuming the gap between two adjacent rows of yams is 80 cm, the width of the movable mechanism 100 can be approximately 65 cm. It should be noted that the specific parameter limits listed above for the movable mechanism are for ease of understanding only and should not be construed as limitations on this embodiment.

[0060] The drug tube support 200 is mounted on the carrier plate 110 and includes a first drug tube support 210 and a second drug tube support 220 extending to both sides of the moving direction of the moving mechanism 100;

[0061] In this embodiment, the first and second drug tube supports 210 and 220 can be three-sided door-shaped frames, two-sided right-angle frames, or column-shaped frames of a certain height. It should be noted that since the drug tube supports are used to support the liquid medicine delivery tube, the more sides a drug tube support has, the wider the area the liquid medicine delivery tube can cover. During implementation, appropriate selection can be made based on the desired spraying accuracy and uniformity requirements.

[0062] It should be noted that the transverse width of the first drug tube holder 210 and the second drug tube holder 220 corresponding to the three-sided door-type frame and the two-sided right-angle frame can be either the width of a ridge or the width of two ridges.

[0063] The liquid medicine delivery mechanism 300 includes a first liquid medicine delivery tube 310 and a second liquid medicine delivery tube 320 . The first liquid medicine delivery tube 310 is laid along the first medicine tube support 210 , and the second liquid medicine delivery tube 320 is laid along the second medicine tube support 220 .

[0064] In this embodiment, the first liquid medicine delivery tube 310 corresponds to the first medicine tube support 210, and the second liquid medicine delivery tube 320 corresponds to the second medicine tube support 220. Laying refers to the installation of the liquid medicine delivery tube from one end to the other end along the medicine tube support; preferably, in the specific implementation process, in order to facilitate installation and use, detachable fasteners such as clamps or buckles can be used to fix the first liquid medicine delivery tube 310 and the second liquid medicine delivery tube 320 when laying.

[0065] It should be noted that since the first and second liquid pesticide delivery pipes 310 and 320 need to transport pesticides and are used outdoors for long periods of time, they are preferably made of corrosion-resistant and aging-resistant materials. The first and second drug tube supports 210 and 220 need to support the liquid pesticide delivery pipes and are therefore preferably made of rigid and corrosion-resistant materials, such as stainless steel or iron with an anti-corrosion coating.

[0066] The medicine supply mechanism 400 is connected to the first medicine liquid delivery pipe 310 and the second medicine liquid delivery pipe 320;

[0067] In this embodiment, the medicine supply mechanism 400 can be placed on the mobile mechanism 100 or outside the mobile mechanism 100. Of course, it can also be partially placed on the mobile mechanism 100 and partially placed outside the mobile mechanism 100. For example, when the crop planting area is far away from the medicine liquid warehouse, the medicine liquid tank 430 can be placed on the mobile mechanism. During the specific implementation process, reasonable adjustments can be made according to the resource environment of the crop planting area.

[0068] Nozzle 500 : Multiple nozzles 500 are provided on each of the first liquid medicine delivery pipe 310 and the second liquid medicine delivery pipe 320 .

[0069] In this embodiment, the first liquid medicine delivery pipe 310 and the second liquid medicine delivery pipe 320 extend in two different directions. At least one ridge of crops on each side of the ridge where the mobile mechanism 100 is located is covered by multiple nozzles 500 on both sides, and there are multiple nozzles on each side, so that the spraying is more uniform.

[0070] The cross-row spraying device for crops in this embodiment uses medicine pipe brackets extending on both sides of the movement direction of the moving mechanism to provide outward support for the two-way medicine liquid delivery pipes, and uses the moving mechanism to drive the two-way medicine liquid delivery pipes to move along the ridges, so as to achieve cross-row spraying of crops with the help of multiple nozzles provided on each of the two-way medicine liquid delivery pipes. It can not only improve the spraying efficiency, but also significantly improve the uniformity of the spraying, and has good universality.

[0071] For some possible implementations, please continue to refer to Figure 1 As shown, the first drug tube support 210 and the second drug tube support 220 are both door-shaped frames;

[0072] The portal frame is connected end to end using three connecting rods. At least one nozzle 500 is provided on each section of the first and second liquid medicine delivery pipes 310 and 320 along each section of the connecting rods, and the nozzles 500 face the inside of the portal frame.

[0073] The cross-row crop spraying device of this embodiment uses a specific door-shaped frame as a supporting component for two liquid medicine delivery pipes, so that the liquid medicine sprayed from the nozzles on each liquid medicine delivery pipe can cover the crops from three directions, namely, above the crops and on both sides of the crops, greatly improving the coverage area of ​​the liquid medicine sprayed from the nozzles on each liquid medicine delivery pipe, thereby further improving the uniformity of spraying.

[0074] In some possible implementations, each section of the first liquid medicine delivery pipe 310 and the second liquid medicine delivery pipe 320 laid along each section of the connecting rod has a plurality of nozzles 500 , and the distance between any two adjacent nozzles 500 is equal.

[0075] The cross-row crop spraying device of this embodiment can avoid the accumulation of pesticides in a single direction and achieve all-round uniform spraying by arranging multiple nozzles at equal intervals on the three sides of the first liquid medicine delivery pipe and the second liquid medicine delivery pipe installed along the door-shaped frame.

[0076] In some possible implementations, each section of the connecting rod is a telescopic sleeve rod, and each section of the telescopic sleeve rod is provided with a telescopic buckle 230;

[0077] Wherein, when spraying pesticides, the height of the door-shaped frame is greater than the height of the crops, and the width of the door-shaped frame is greater than the width of the crop ridges.

[0078] Preferably, in the specific implementation process, since the height and width of the door-type frame are adjustable, the vertical retractable rods can be adjusted with reference to the height of the crops, and the horizontal retractable rods can be set with reference to the crop planting width and the spraying uniformity requirements. Taking the medicine tube bracket on one side as an example, if the demand for uniform spraying is general and the ridge width is relatively narrow, the length of the horizontal retractable rods can be adjusted to be equivalent to the width of two rows of crops; if the demand for uniform spraying is high or the ridge width is relatively wide, the length of the horizontal retractable rods can be adjusted to be equivalent to the width of a single ridge of crops; in addition, the medicine tube brackets on both sides can be adjusted separately according to the crop status of the corresponding ridge, and there is no need to set the width and height of the two to be completely consistent.

[0079] The crop cross-row spraying device of this embodiment uses a telescopic sleeve rod connected to form a three-sided door-type frame, so that the medicine tube brackets on both sides can flexibly adjust the longitudinal height and lateral width, thereby being able to adapt to the height of various types of crops and various periods and / or the planting spacing of crops, significantly improving flexibility.

[0080] For some possible implementations, see Figure 2 As shown, the drug delivery support 200 further includes a foldable connecting frame 240 for connecting the carrier plate 110 with the first drug delivery support 210 and the second drug delivery support 220;

[0081] When the foldable connecting frame 240 is in the unfolded state, the first drug tube support 210 and the second drug tube support 220 are both perpendicular to the supporting plate 110 . When the foldable connecting frame 240 is in the folded state, the first drug tube support 210 and the second drug tube support 220 are both parallel to the supporting plate 110 .

[0082] In a specific implementation process, the foldable connecting frame can realize the folding function by cooperating a folding rod with an articulated support, cooperating a movable top rod with an articulated support, or cooperating a detachable connecting rod with an articulated support.

[0083] For some possible implementations, see Figure 3 As shown, the foldable connecting frame 240 includes a mounting base 241, a first folding rod 242 and a second folding rod 243;

[0084] The mounting base 241 is fixed to the carrier plate 110 . The end of the first drug tube holder 210 near the carrier plate 110 is pivotally connected to the mounting base 241 . The end of the second drug tube holder 220 near the carrier plate 110 is pivotally connected to the mounting base 241 .

[0085] One end of the first folding rod 242 is pivotally connected to the first drug tube support 210 , and the other end of the first folding rod 242 is pivotally connected to the mounting base 241 ;

[0086] One end of the second folding rod 243 is pivotally connected to the second drug tube support 220 , and the other end of the second folding rod 243 is pivotally connected to the mounting base 241 .

[0087] The cross-row crop spraying device of this embodiment utilizes the folding characteristics of the foldable connecting frame to connect the two-way drug tube bracket to the supporting plate, so that the drug tube bracket can be kept vertical or folded horizontally for easy storage and movement.

[0088] For some possible implementations, see Figure 1 and Figure 4 As shown, the drug supply mechanism 400 includes a drug inlet and outlet four-way 410 with two inlets and two outlets, a drug liquid pump 420 and a drug liquid tank 430;

[0089] The liquid medicine pump 420 and the liquid medicine tank 430 are placed on the carrier plate 110 , and the liquid inlet of the liquid medicine pump 420 is connected to the liquid medicine tank 430 ;

[0090] It should be noted that although Figure 1 The liquid medicine reservoir and the third liquid medicine delivery pipe are not shown in the figure, but in the specific implementation process, the liquid medicine can be led from the liquid medicine reservoir to the reserved interface of the inlet and outlet four-way medicine through the third liquid medicine delivery pipe as needed (such as Figure 1 The front-end interface of the medicine inlet and outlet four-way 410);

[0091] One inlet of the medicine inlet and outlet four-way valve 410 is connected to the liquid outlet of the medicine pump 420, and the other inlet is reserved to be connected to the medicine reservoir for storing and supplying a large amount of medicine through the third medicine delivery pipe when needed. One outlet is connected to one end of the first medicine delivery pipe 310 close to the second medicine delivery pipe 320, and the other outlet is connected to one end of the second medicine delivery pipe 320 close to the first medicine delivery pipe 310.

[0092] The crop cross-row spraying device of this embodiment adopts a medicine supply mechanism with a specific structure to divert the medicine liquid into two medicine liquid delivery pipes. It is suitable for most crop planting sites and has low dependence on the external environment of the crop planting area.

[0093] For some possible implementations, see Figure 5 As shown, the drug delivery support 200 further includes an adjustable connecting tube 250;

[0094] One end of the adjustable connecting tube 250 is fixed to the end of the longitudinal connecting rod of the first drug tube support 210 that is close to the second drug tube support 220 and is connected to the first drug tube support 210 and is away from the supporting plate 110;

[0095] The other end of the adjustable connecting tube 250 is fixed to an end of the longitudinal connecting rod close to the first drug tube support 210 and connected to the second drug tube support 220 away from the supporting plate 110 .

[0096] The cross-row crop spraying device of this embodiment connects the tops of the first medicine tube bracket and the second medicine tube bracket together through an adjustable connecting pipe, which not only makes the lateral width adjustment range of the two medicine tube brackets larger, but also ensures that the medicine tube brackets are more stable when upright, which helps to improve the safety of spraying operations.

[0097] For some possible implementations, please continue to refer to Figure 5 As shown, the drug delivery support 200 further includes a connecting support rod 260;

[0098] One end of the connecting support rod 260 is fixed to the middle of the longitudinal connecting rod close to the second drug tube support 220 and connected to the first drug tube support 210;

[0099] The other end of the connecting support rod 260 is fixed to the middle of the longitudinal connecting rod close to the first drug tube support 210 and connected to the second drug tube support 220 .

[0100] The cross-row spraying device for crops in this embodiment connects the longitudinal connecting rods of the first drug tube bracket and the second drug tube bracket together by connecting the support rod, so that the two drug tube brackets are not easily displaced or separated, further improving the stability of the drug tube bracket.

[0101] For some possible implementations, see Figure 6As shown, the moving mechanism 100 includes an electric trolley 120 , and the carrying plate 110 is fixed on the electric trolley 120 ;

[0102] The moving mechanism 100 further includes a power-assisting handle 130 fixed to the electric trolley 120 .

[0103] The cross-row crop spraying device of this embodiment adopts an electric trolley as the driving source of the entire spraying device in its moving mechanism, which can realize unmanned operation and reduce labor costs. The moving speed of the electric trolley is easy to control and adjust, which can further improve the uniformity and efficiency of spraying. On the other hand, a power-assisting handle is also provided on the moving mechanism for convenient manual operation, so that the spraying device has both manual and non-manual driving modes and has better flexibility.

[0104] In some possible implementations, taking yam as an example of the crop to be sprayed, the height and width of the first drug tube bracket and the second drug tube bracket in the cross-row spraying device for crops described in the above embodiments are adjusted so that the two liquid medicine delivery pipes can cover the area where the yam needs to be sprayed, and the mobile mechanism is driven to move between ridges to complete the spraying operation.

[0105] The cross-row spraying device for crops in this embodiment can solve the problem of poor passability of spraying personnel or existing spraying machinery when the yam planting ridge spacing is about 90 cm; the length of the connecting rod can be telescopically adjusted, so that the height and width of the medicine tube bracket can be adjusted, and the liquid medicine delivery pipe installed on the medicine tube bracket can also be adjusted accordingly according to the height and width of the medicine tube bracket. The atomization range of the nozzle provided on the liquid medicine delivery pipe can cover the different heights of one or more rows of crops, and 3 to 4 rows can be sprayed at a time, and the spraying is relatively uniform. There is no need to use higher concentration drugs to ensure the spraying effect, which solves the problems of uneven spraying and high drug concentration of drones; it can realize automatic walking and automatic spraying, reduce manual operation, and save labor costs; the interface reserved in the four-way joint for inlet and outlet of medicine can be remotely connected to the liquid medicine reservoir through the third liquid medicine delivery pipe, and the opening of the corresponding valve can be controlled from the liquid medicine source (liquid medicine reservoir) to realize remote adjustment of atomization.

[0106] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
