Description

Technical Field

[0001] This utility model relates to the field of fruit tree planting, and more specifically, to a fruit tree canopy penetrating spray nozzle device. Background Technology

[0002] Fruit tree cultivation aims to obtain high-quality fruit. It optimizes space utilization through scientific seed selection, rational orchard planning (considering soil fertility, sunlight, and drainage conditions), and the adoption of dwarf dense planting or three-dimensional cultivation models. It combines precise water and fertilizer management (such as drip irrigation and soil testing-based fertilizer application), shaping and pruning to control tree vigor, and green pest and disease control (combining biological control and physical trapping). It also relies on mechanized and intelligent technologies (such as automatic pollinators and canopy-penetrating sprayers) to improve production efficiency, ultimately achieving high-yield, high-quality, and sustainable modern agricultural activities. In order to penetrate the dense canopy foliage to spray pesticides on fruit trees, a fruit tree canopy-penetrating sprayer nozzle device is required.

[0003] A search revealed that Chinese patent CN117717053A discloses an "electric large-scale metering spray irrigation machine," which includes a walking mechanism, a support connected to the walking mechanism, a main water pipe mounted on the support, a spray irrigation device connected to the main water pipe, and a hollow spray pipe with multiple nozzles spaced apart. The spray pipe is connected to the support via a lifting device; the spray pipe is connected to a pesticide storage tank via a metering and conveying device. The lifting device includes a rotating power pipe arranged along the extension direction of the spray pipe, and a power pipe drive device for driving the rotating power pipe to rotate. A steel wire rope is wound around the rotating power pipe, and the spray pipe is suspended from the free end of the steel wire rope. However, the following defects still exist:

[0004] (1) The fruit tree canopy penetration spray nozzle devices currently available on the market are not easy to adjust the penetration force, so they cannot apply different penetration forces to different types of fruit trees. When facing different fruit trees, the penetration force is often insufficient or too large, which can damage the fruit trees. This reduces the nozzle's adaptability to the environment, increases the demand for different types of nozzle devices, and increases the cost of the work.

[0005] (2) No replaceable gripping point is provided. If the gripping point is damaged, the entire structure needs to be replaced, which reduces the overall service life of the device and affects the rapid progress of subsequent work. To address this, a fruit tree canopy penetrating spray nozzle device is proposed. Utility Model Content

[0006] The purpose of this invention is to address the current problem of not providing adjustable penetration strength.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] As shown in 1-5, this embodiment proposes a canopy-penetrating spray nozzle device for fruit trees, including a fixed nozzle 1, a connecting ring 3 fixedly connected to the outer wall of the fixed nozzle 1, a bearing 4 fixedly connected to the inner wall of the connecting ring 3, a movable nozzle 5 fixedly connected to the inner wall of the bearing 4, a limiting block 6 fixedly connected to the outer wall of the movable nozzle 5, a movable column 7 movably connected to one side of the limiting block 6, and an inner spring 8 fixedly connected to one end of the movable column 7.

[0030] A hollow block 9 is fixedly connected to one end of the inner spring 8, a liquid permeation plate 10 is fixedly connected to the inner wall of the fixed nozzle 1, a liquid permeation plate 21 is fixedly connected to the inside of the movable nozzle 5, and a nozzle 12 is fixedly connected to one end of the movable nozzle 5. This makes the fruit tree canopy penetrating spray nozzle device more convenient to use, allows for adjustment of the penetration force during spraying, improves the device's adaptability to the environment, avoids problems of insufficient penetration or excessive penetration force, reduces the need for different types of nozzle devices, and lowers the operating costs.

[0031] As shown in 1-5, in a preferred embodiment, based on the above method, the outer wall of the fixed nozzle 1 is movably connected with mounting bolts 13, and the number of mounting bolts 13 is four, which facilitates locking the two components. The outer wall of the mounting bolts 13 is movably connected with mounting arc plate 14, and the length of mounting arc plate 14 is less than the length of fixed nozzle 1, which facilitates the connection of other components. A grip handle 15 is fixedly connected to one side of mounting arc plate 14, and the width of grip handle 15 is less than the length of mounting arc plate 14, which can provide a fulcrum for the worker's grip.

[0032] One end of the fixed nozzle 1 is fixedly connected to a rear threaded tube 16, and the outer wall of the rear threaded tube 16 is movably connected to a threaded lock 2, which can lock the structure to the external liquid supply pipeline.

[0033] One side of the liquid permeable plate 10 is movably connected to one side of the liquid permeable plate 11, and the liquid permeable plate 10 and the liquid permeable plate 11 are the same size and shape. The permeability of the liquid can be adjusted by adjusting the alignment of the holes of the liquid permeable plate 10 and the liquid permeable plate 11. The outer wall of the movable column 7 is movably connected to the interior of the hollow block 9 through the inner spring 8, and the length of the movable column 7 is less than the internal length of the hollow block 9, so that the position of the movable nozzle 5 can be locked after reaching the appropriate angle.

[0034] Specifically, when using this canopy-penetrating spray nozzle device for fruit trees: first, the screw lock 2 is rotated to lock the rear threaded tube 16 with the external liquid supply pipe. When the liquid supply pipe supplies liquid into the fixed nozzle 1, it passes through the liquid permeation plate 10 and liquid permeation plate 11. At this time, pressing the movable column 7 causes the inner spring 8 to contract, thereby causing the movable column 7 to retract into the hollow block 9. Then, rotating the movable nozzle 5 adjusts the alignment of the holes in the liquid permeation plate 10 and liquid permeation plate 11. When the alignment is higher, the internal hydraulic pressure of the fixed nozzle 1 is greater. This results in stronger penetration of the liquid sprayed from the nozzle 12. When the orifice alignment is low, the hydraulic pressure inside the fixed nozzle 1 is small, resulting in less penetration of the liquid sprayed from the nozzle 12. When the appropriate angle is reached, the movable column 7 passes through the limiting block 6, thereby fixing the positions of the fixed nozzle 1 and the movable nozzle 5. The spray angle and direction of the nozzle 12 can be adjusted by picking up the grip handle 15. If it is necessary to disassemble the grip handle 15, rotate and remove the mounting bolt 13. Then the mounting arc plate 14 and the grip handle 15 can be removed and replaced.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
