Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a spraying mechanism that facilitates the spraying of pesticide solutions onto crops. Background Technology
[0002] In the process of crop cultivation, it is sometimes necessary to apply various chemical sprays. When dealing with crops that are a certain height (such as grapes, kiwis, and loofahs grown on trellises), a sprayer provided by, for example, Chinese utility model patent No. CN202322441406.0 (authorization announcement No. CN220756285U) entitled "A Multifunctional High-Pressure Electric Sprayer" is usually used to spray chemical solutions.
[0003] However, crops typically require spraying chemical solutions on both sides. Using only the aforementioned sprayer would require the user to spray the other side after spraying one side, resulting in low efficiency and sometimes even forgetting to spray only one side. Therefore, existing technology includes a spraying mechanism provided by the Chinese utility model patent CN200720039927.1 (authorization announcement number CN201049325Y), entitled "Double-Headed Pesticide Sprayer Nozzle." This spraying mechanism includes a main body that can be attached to the sprayer, with two forked nozzles on the main body, thereby achieving the function of simultaneously spraying both sides of the crop.
[0004] However, taking the application of a dormancy-breaking agent to grapes as an example, the above-mentioned spraying mechanism still has the following defects in actual use: Firstly, such as... Figure 1 The image shows a trellis for growing grapes, including a first stalk 21' for grapevines to climb on, and second stalks 22' slightly higher than the first stalk 21' on both sides, so that the buds 11' on the stalks 1' can grow towards the second stalks 22' after breaking dormancy and climb to form new branches. Figure 1 The dotted arrows shown indicate the growth direction of bud 11'. Therefore, when using the above-mentioned spraying mechanism to spray chemical solution on grape branches 1', sometimes the first rod 21' and branch 1' have difficulty passing between the two nozzles; secondly, because the volume of bud 11' is relatively small, a large amount of dormancy-breaking agent will be wasted during the spraying process. Summary of the Invention
[0005] The first technical problem to be solved by this utility model is to provide a spraying mechanism that can improve work efficiency, especially suitable for grapes grown on trellises, in light of the above-mentioned existing technology.
[0006] The second technical problem to be solved by the utility model is to provide a spraying mechanism capable of avoiding waste of chemical solution during spraying.
[0007] The utility model discloses a technical scheme that solves the above technical problem: the spraying mechanism for crops, including the slender main part, the main part includes the proximal end of user's holding and the distal end opposite to the proximal end, the distal end extends two branch channels in the form of bifurcation, the upper end of each branch channel is equipped with the spray head for the chemical solution to spray, its characterized in that: the lower end of each branch channel is connected through the first connecting section that crosses the central axis of the main part, and the first connecting section and two branch channels surround the space for the first rod of the branch of the crop to be sprayed to pass through.
[0008] In order to solve the second technical problem, preferably, it also includes the collection assembly adjacent to each spray head, so as to recycle the chemical solution sprayed from each spray head. The collection assembly can be in communication with a container such as a recycling bucket, or directly in communication with the sprayer, so as to recycle and reuse the chemical solution, effectively avoiding the situation of a large amount of waste during spraying.
[0009] In order to guide the excess chemical solution sprayed from each spray head, preferably, the collection assembly includes a sheet-shaped flow guide extending along the extension direction of each branch channel, including an outer side towards the upper end and an inner side towards the lower end, and the flow guide is provided with a channel for the first rod of the branch of the crop to be sprayed to pass through. The flow guide extends along the extension direction of each branch channel, which can guide the excess chemical solution to flow downward along the flow guide, and finally be collected for reuse. In order to avoid interference with the first rod, the flow guide needs to be provided with the above-mentioned channel. In this way, the user can directly use the spraying mechanism to move along the first rod to complete the spraying work.
[0010] Further, in order to better collect the excess chemical solution sprayed from each spray head, preferably, the height of the inner side is lower than the height of the outer side, and the outer side of the flow guide gradually and smoothly extends downward to the inner side, and the part of the outer side extending to the inner side is at least partially concave. The outer side of the flow guide gradually and smoothly extends downward, which can guide the chemical solution to flow from top to bottom, and the part of the outer side extending to the inner side is at least partially concave, which is to play a certain role of shielding the spray head and better collect the sprayed chemical solution.
[0011] In order to communicate with the container for recovering the chemical solution, preferably, the inner side edge further surrounds a liquid storage cavity formed, and a pipe is arranged at the lower part of the liquid storage cavity for recovering the chemical solution. The liquid storage cavity is used for temporarily storing the chemical solution collected by the flow guide from the top to the bottom, and the pipe arranged at the lower part of the liquid storage cavity can easily make the focused chemical solution flow into the container for collecting the chemical solution.
[0012] In order to avoid that the collected chemical solution is mixed with too many impurities, preferably, a filter is arranged on the liquid storage cavity for filtering the chemical solution guided by the flow guide. The filter can be arranged at a position such as the upper part of the liquid storage cavity, so that the chemical solution guided by the flow guide is filtered before flowing into the liquid storage cavity.
[0013] In order to enable the flow guide to be installed adjacent to the spray head, preferably, the main body is connected with the flow guide, and correspondingly, a through hole is arranged on the flow guide for the main body to pass through. Since the spray head is installed on the branch channel extending from the main body, and the flow guide needs to be arranged adjacent to the spray head to collect the chemical solution, the flow guide needs to be installed on the main body, and the through hole is arranged for the main body to pass through the flow guide, so that the flow guide is connected with the main body.
[0014] Further, in order to enable the flow guide to be fixed, preferably, the first connecting section at least partially extends towards the distal end of the main body to form a second connecting section, the second connecting section is connected with the main body in an insertion manner, and the end of the second connecting section is at least partially outwardly protruding to form a first flange, and correspondingly, the distal end of the main body is at least partially outwardly protruding to form a second flange, and the first flange and the second flange jointly clamp the flow guide. If the flow guide is simply connected with the main body, it is unstable, and considering that the flow guide can be made of hard metal materials such as iron, it will be corroded by the chemical solution after long-term use. Therefore, the main body and the first connecting section are arranged in a split structure connected by the second connecting section, which can jointly clamp the sheet-shaped flow guide through the first flange of the second connecting section and the second flange of the main body, and is easy to disassemble, maintain or replace the branch channel and the flow guide.
[0015] The "fluid communication" in the utility model refers to the spatial position relationship between two components or parts (hereinafter collectively referred to as the first part and the second part), i.e. the fluid (gas, liquid or mixture of the two) can flow or / and be transported from the first part to the second part along the flow path, which can be directly connected between the first part and the second part, or indirectly connected between the first part and the second part through at least one third party, which can be a fluid passage such as a pipeline, a channel, a conduit, a flow guide, a hole, a groove, etc., or a chamber allowing the fluid to flow, or a combination thereof.
[0016] Compared with the prior art, the advantages of the utility model lie in: the branch passageways on the spray mechanism main body are connected through the first connecting section crossing the central axis of the main body, and the first connecting section and the two branch passageways enclose a certain space, thereby ensuring that the first rod member for climbing the branches of the crops to be sprayed passes through, especially suitable for grape planted in the shed frame.

[0025] The utility model is further described in detail below in combination with the embodiment of the drawings.
[0026] As Figures 2-4 shown, it is a preferred embodiment of the utility model. As Figure 2As shown, the spraying mechanism for crops in this embodiment includes an elongated body 11. The body 11 includes a proximal end 111 for the user P to hold and a distal end 112 opposite to the proximal end 111. The distal end 112 extends into two branch channels 12 in a forked manner. The upper end 121 of each branch channel 12 is provided with a nozzle 122 for spraying chemical solution. The lower end 123 of each branch channel 12 is connected by a first connecting section 13 that intersects the central axis Z of the body 11. The first connecting section 13 and the two branch channels 12 form a space through which a first rod c1, on which a branch b1 of the crop to be sprayed is attached, passes. In this embodiment, the distance between the two nozzles 122 is 50 cm. Since the buds b2 on the branch b1 are small, in order to avoid a large waste of chemical solution, the spraying mechanism also includes a collection component 2 adjacent to each nozzle 122 to recover the chemical solution sprayed from each nozzle 122. In this embodiment, the proximal end 111 of the main body 11 is attached to the sprayer A so as to be in fluid communication with the sprayer A, and the collection component 2 is in communication with the sprayer A so that the recovered chemical solution can be directly used for spraying.
[0027] Regarding the specific components of collection component 2, such as Figure 3 As shown, the collecting assembly 2 includes a sheet-shaped guide 21 extending along the extension direction of each branch channel 12, including an outer side 211 facing the upper end 121 and an inner side 212 facing the lower end 123. The guide 21 has a channel 213 through which a first rod c1, onto which a branch b1 of the crop to be sprayed is attached, passes. The function of this channel 213 is to prevent interference between the guide 21 and the first rod c1. Figure 2 As shown, user P can stand behind the spray mechanism and directly use it to move along the first rod c1 to complete the spraying operation. See also Figure 4 The inner side 212 of the flow guide 21 is lower in height than the outer side 211, and the outer side 211 of the flow guide 21 gradually and smoothly slopes downward to the inner side 212. The portion of the outer side 211 extending to the inner side 212 is at least partially concave. In this embodiment, this concave shape is particularly evident in the outer side portion of the flow guide 21. This concave shape can provide a certain covering effect, better collecting the sprayed chemical solution, and allowing excess chemical solution to flow from top to bottom under the guidance of the flow guide, such as... Figure 4As shown, second rods c2 are provided above both sides of the first rod c1. The dotted lines in the figure indicate the spray direction, so the concave shape also needs to prevent the guide 21 from contacting the second rods c2. A liquid storage chamber 214 is also formed around the inner side 212, and a pipe 22 for recovering the chemical solution is provided at the lower part of the liquid storage chamber 214. The pipe 22 is connected to the sprayer A, so that the chemical solution collected in the liquid storage chamber 214 can easily flow into the sprayer A. Furthermore, a filter element 23 for filtering the chemical solution guided by the guide 21 is provided on the liquid storage chamber 214. The filter element 23 is located at the upper part of the liquid storage chamber 214, so that the chemical solution guided by the guide 21 is filtered before flowing into the liquid storage chamber 214, to prevent the collected chemical solution from being contaminated with too many impurities.
[0028] Finally, considering the installation of the guide tube 21, the main body 11 is connected to the guide tube 21. Correspondingly, the guide tube 21 is provided with a through hole 215 for the main body 11 to pass through. Since the nozzle 122 is installed on the branch channel 12 extending from the main body 11, and the guide tube 21 needs to be placed adjacent to the nozzle 11 to collect the chemical solution, the guide tube 21 needs to be installed on the main body 11. The through hole 215 is provided so that the main body 11 can pass through the guide tube 21, thereby allowing the guide tube 21 to be connected to the main body 11. The first connecting segment 13 extends at least partially toward the distal end 112 of the main body 11 to form a second connecting segment 14. The second connecting segment 14 and the main body 11 are connected by an insertion method. The end of the second connecting segment 14 protrudes at least partially outward to form a first flange 141. Correspondingly, the distal end of the main body 11 protrudes at least partially outward to form a second flange 113. The first flange 141 and the second flange 113 together hold the guide tube 21. The distal end of the main body 11 is also provided with a threaded structure, which sets the main body 11 and the first connecting section 13 as separate structures connected by the second connecting section 14. On the one hand, the first flange 141 of the second connecting section 13 and the second flange 113 of the main body 11 can jointly clamp the sheet-like guide 21. On the other hand, it is easy to disassemble, maintain or replace the branch channel 12 and the guide 21.
[0029] Example 2
[0030] like Figures 5-6 As shown, the structure is basically the same as that of Embodiment 1. The difference is that the central axis Z of the main body 11 in this embodiment can form a plane together with each branch channel 12. Compared with the user P standing at the rear in Embodiment 1, the user P in this embodiment is more like standing on the side, and one of the nozzles 122 will be aimed at the user P, so that the guide 21 also has the function of preventing the chemical solution from being sprayed onto the user P.
[0031] Example 3
[0032] likeFigure 7 As shown, the structure is basically consistent with that of Example 1, and the difference is that the main body 11 and the branch channel 12 in this example are both flexible pipe bodies, which are installed on the rod by buckling.
[0033] Example 4
[0034] As shown, the structure is basically consistent with that of Example 1, and the difference is that the main body 11 and the branch channel 12 in this example are both flexible pipe bodies, which are installed on the rod by buckling. Figure 8 As shown, the structure is basically consistent with that of Example 1, and the difference is that the height of the spray head 122 in this example is higher, and the spray head 122 is slightly inclined downward, and the dotted line in the figure represents the direction of the spray, which can more directly spray the upward growing bud b2 from top to bottom.
