Description

Technical Field

[0001] This utility model relates to the technical field of tea garden planting, and in particular to a spraying device suitable for tea gardens. Background Technology

[0002] Tea gardens are mostly located on hills or gentle slopes with slightly acidic soil and good drainage. To facilitate management and harvesting, tea trees are often planted in neat rows and pruned into an arc-shaped canopy. The tea tree planting process requires year-round pruning, fertilization, plant protection, and harvesting. During the tea tree planting process, nutrient solution, biological pesticides, or antifreeze are evenly sprayed onto the leaves using a spraying device to supplement trace elements, prevent and control pests and diseases, and regulate the microclimate.

[0003] In existing technologies, spraying in tea gardens typically uses backpack or stretcher-type sprayers. The sprayed pesticide settles by gravity alone. Due to the obstruction of the upper leaves, the amount of pesticide deposited on the middle and lower leaves is insufficient. This requires operators to swing the handheld nozzle to spray the lower leaves. However, the uniformity of the pesticide solution during swinging spraying depends on the operator's skill level. Moreover, it is difficult for operators to move between narrow tea bushes, carrying sprayers or stretchers in muddy or uneven fields, which increases physical exertion and reduces work efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a spraying device suitable for tea gardens. The first driving component drives the nozzle in the spraying component to swing back and forth, so as to evenly cover the leaves with the liquid medicine. Furthermore, the walking component reduces labor intensity and improves work efficiency.

[0006] To achieve the above objectives, this utility model proposes a spraying device suitable for tea gardens, comprising a body, a support rod, a first drive assembly, a spraying assembly, a liquid supply assembly, and a walking assembly. The support rod is rotatably connected to the body. The first drive assembly is disposed inside the body, with one end connected to the support rod. The spraying assembly is disposed inside the support rod. The support assembly includes a connecting rod, a mounting base, a connecting component, a nozzle, and a second drive assembly.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following description, in conjunction with the accompanying drawings, describes a spraying device suitable for tea gardens according to an embodiment of the present invention.

[0017] like Figures 1-7 As shown, a spraying device suitable for tea gardens according to an embodiment of the present invention may include a body 1, a support rod 2, a first drive assembly 3, a spraying assembly 4, a liquid supply assembly 5, and a walking assembly 6, wherein...

[0018] The support rod 2 is rotatably connected to the body 1.

[0019] The first drive assembly 3 is located inside the body 1, and one end of the first drive assembly 3 is connected to the support rod 2.

[0020] The spray assembly 4 is located inside the support rod 2. The spray assembly 4 includes a connecting rod 41, a mounting base 42, a connecting component 43, a nozzle 44, and a second drive assembly 45. The connecting rod 41 is movably located inside the support rod 2, the connecting component 43 is located inside the connecting rod 41, the mounting base 42 is located on the support rod 2, and the other end of the mounting base 42 is located on the connecting rod 41 via the connecting component 43. The nozzle 44 is located inside the mounting base 42, and the second drive assembly 45 is located inside the machine body 1.

[0021] The liquid supply component 5 is installed on the body 1.

[0022] The walking component 6 is located on the lower part of the body 1.

[0023] Specifically, the body 1 serves as the base of the device, providing stable support for the device.

[0024] In this embodiment, storage slots are provided on both sides of the upper part of the body 1 to store the support rod 2 after it is rotated.

[0025] Two support rods 2 are symmetrically rotated and installed in the storage slots opened on both sides of the upper part of the machine body 1. After the spraying operation is completed, the support rods 2 rotate 90 degrees and are completely stored in the storage slots, so that the nozzles 44 are not hit by tea tree branches. At the same time, the height of the device is lowered, allowing it to move flexibly between narrow tea ridges.

[0026] In this embodiment, the support rod 2 is a hollow rod with a swing groove on one side to avoid the swing position of the nozzle 44. The hollow rod 2 provides space for the connecting rod 41 to slide, and the lighter weight of the hollow rod reduces the load and energy consumption on the first drive assembly 3.

[0027] The first drive assembly 3 is mounted on the support frame and is used to control the rotation of the support rod 2.

[0028] In this embodiment, the first drive component 3 can be an electric push rod to drive the support rod 2 to adjust between two positions: vertical support and horizontal storage under the positioning of the horizontal rotating shaft, and meet the requirements of dust prevention, moisture prevention and rapid drive in tea garden spraying.

[0029] The spray assembly 4 is installed inside the support rod 2 and is used to spray the tea tree after the first drive assembly 3 drives the support rod 2 to support it vertically. The spray assembly 4 includes a connecting rod 41, a mounting base 42, a connecting assembly 43, a nozzle 44, and a second drive assembly 45.

[0030] The connecting rod 41 is slidably installed inside the support rod 2. Under the drive of the second drive assembly 45, the connecting rod 41 can slide up and down inside the support rod 2.

[0031] In this embodiment, the connecting rod 41 is a hollow rod, and both sides are provided with clearance grooves for avoiding the swing of the nozzle 44 and for connecting the water pipe of the liquid supply component 5. The hollow rod reduces the load and energy consumption on the second drive component 45.

[0032] Several mounting bases 42 are rotatably mounted on the inner side wall of the support rod 2 via a horizontal rotating shaft, forming a swing rotation center. The other end of the mounting base 42 is mounted on the inner wall of the connecting rod 41 via a connecting assembly 43. The mounting base 42 is used to fix the nozzle 44 and to connect the nozzle 44 and the liquid supply assembly 5 to ensure continuous liquid supply during swing spraying.

[0033] The connecting component 43 is installed inside the connecting rod 41 and is used to connect several mounting seats 42 to the connecting rod 41. Since one end of the mounting seat 42 is rotatably mounted on the inner side wall of the support rod 2 through a horizontal rotating shaft, when the connecting rod 41 moves up and down, it drives the end of the mounting seat 42 with the nozzle 44 to swing back and forth through the connection of the connecting component 43.

[0034] Several nozzles 44 are installed inside the corresponding mounting base 42, with their nozzles facing outwards and sealed to the liquid flow channel of the mounting base 42.

[0035] In this embodiment, the connection between the mounting base 42 and the nozzle 44 can be quickly plugged in and replaced. A sealing ring is installed at the connection between the nozzle 44 and the mounting base 42 to prevent the liquid from leaking out under pressure. At the same time, the mounting base 42 prevents the nozzle 44 from falling off during the reciprocating swing process, ensuring the stability of the spray direction.

[0036] The second drive assembly 45 is installed inside the body 1 and is used to drive the connecting rod 41 to reciprocate linearly up and down inside the support rod 2.

[0037] In one embodiment of this utility model, the second drive assembly 45 can be an electric push rod, with a push plate mounted on its top. The upper end of the push plate abuts against the lower end of the connecting rod 41. An elastic mechanism is installed inside the upper end of the support rod 2. The elastic mechanism pushes the connecting rod 41 to reset. The extension and retraction of the electric push rod drives the push plate to reciprocate up and down. During the upward movement of the push plate, the connecting rod 41 slides upward synchronously. After the push plate moves downward, the connecting rod 41 loses support and is driven to move downward to reset by the elastic mechanism. When the support rod 2 is retracted... The electric push rod drives the push plate to the lower end of the slide. When the support rod 2 rotates to the horizontal direction, the internal connecting rod 41 also rotates to the horizontal direction. The lower end of the connecting rod 41 rotates synchronously, disengaging from the support of the push plate. When the support rod 2 is vertically supported, the connecting rod 41 slides down due to the elastic mechanism until it is in contact with the upper end of the push plate, thus connecting the connecting rod 41 to the second drive assembly 45. No additional quick-release structure is needed to ensure accurate resetting. At the same time, the second drive assembly 45 is waterproof and dustproof to adapt to the high humidity and dusty environment of the tea garden.

[0038] The liquid supply assembly 5 is installed on the body 1 and is used to deliver the liquid medicine to the mounting base 42 and spray it out through the nozzle 44.

[0039] The walking component 6 is installed on the lower part of the body 1 to support the weight of the device and drive the component to move.

[0040] It should be noted that the liquid medicine is added to the inside of the liquid supply component 5 for storage, and then the device is moved to the tea tree ridge by the walking component 6. After it is in place, the first drive component 3 drives the support rod 2 to rotate to a vertical state. At this time, the second drive component 45 is connected to the lower end of the connecting rod 41. The liquid supply component 5 pumps the liquid medicine to the mounting base 42 at high pressure and sprays it out through the nozzle 44. While the nozzle 44 sprays the liquid medicine in a mist, the second drive component 45 drives the connecting rod 41 to slide up and down. Under the connection of the connecting rod 41, the mounting base 42 and the nozzle 44 swing back and forth, spraying the liquid medicine in a fan shape in multiple directions, so that the medicine is evenly covered on the leaves of each layer.

[0041] In one embodiment of this utility model, such as Figure 6 As shown, the connecting assembly 43 may include a guide groove and a guide block. The guide groove is formed on one side of the connecting rod 41, and the guide block is movably disposed inside the guide groove. The guide block is disposed on the front and rear sides of the mounting base 42.

[0042] The guide groove is located on the front side of the mounting base 42 of the connecting rod 41 and extends through the connecting rod 41.

[0043] Two guide blocks are slidably connected inside opposite guide grooves. The guide blocks are fixedly installed on the mounting base 42 by bolts, and the guide blocks can slide laterally inside the guide grooves.

[0044] It should be noted that when the connecting rod 41 moves up and down in a straight line, the guide block slides inside the guide groove and pushes the mounting base 42 to swing. The mounting base 42 drives the nozzle 44 to swing, spraying the liquid in a fan shape to evenly cover the surface and back of the blade.

[0045] In one embodiment of this utility model, such as Figure 1 As shown, the liquid supply assembly 5 may include a liquid storage tank and a liquid pump. The liquid storage tank is located inside the body 1, and the liquid pump is located on the body 1. The liquid pump is connected to the liquid storage tank and is connected to the mounting base 42 through a water pipe.

[0046] Specifically, the liquid storage tank is installed at the top of the body 1 and is used to store the liquid medicine.

[0047] The liquid pump is installed on the machine body 1 and connected to the inside of the liquid storage tank. It continuously and stably pressurizes and delivers the liquid medicine inside the liquid storage tank to each mounting base 42. The pressurized liquid medicine is then sprayed out through the nozzle 44 via the mounting base 42.

[0048] In one embodiment of this utility model, such as Figure 1 As shown, the walking component 6 may include a walking component and a driving component. The walking component is disposed on the body 1, and the driving component is disposed inside the body 1. The driving component is electrically connected to the first driving component 3 and the second driving component 45.

[0049] Specifically, the walking components are installed on both sides of the machine body 1 to support the device and move it between the muddy ridges of the tea garden.

[0050] The drive unit is installed inside the body 1 and is used to drive the walking component to move the device. The drive unit is electrically connected to the first drive assembly 3, the second drive assembly 45 and the liquid pump, so that they can all be controlled synchronously by the drive unit.

[0051] In one embodiment of the present invention, the drive unit may consist of a storage battery and a controller. The storage battery is used to provide energy to the electrical components inside the device, and the controller is used to control the first drive component 3, the second drive component 45 and the liquid pump inside the device.

[0052] In summary, the spraying device for tea gardens according to this utility model embodiment controls the up-and-down swing of the nozzle during spraying, so that the liquid is swept in a fan shape and evenly covers the surface and back of the leaves, ensuring a stable production of the pesticide and eliminating the need for repeated manual swinging spraying, thus improving the uniformity of the spray. After spraying, by storing the support rod and its internal spraying components, the nozzle is prevented from being hit by tea branches, and the height of the device is reduced, allowing it to move flexibly between narrow tea rows.
