Description

Technical Field

[0001] This utility model relates to the field of agricultural plant protection technology, and in particular to a device for precise atomization application of pesticides for bacterial angular leaf spot of melon and droplet recovery. Background Technology

[0002] The melon bacterial angular leaf spot pesticide atomization precision application and droplet recovery device is a specialized piece of equipment for the prevention and control of melon bacterial angular leaf spot. With precision application and droplet recovery as its core functions, it converts the pesticide into fine droplets for precise, targeted spraying to disease-prone areas of the melon, improving the bactericidal effect. Simultaneously, the droplet recovery module captures and recycles drifting droplets, effectively solving the problems of low efficiency, high pollution, and pesticide waste associated with traditional pesticide application methods. It not only improves disease control and reduces pesticide usage to lower costs, but also reduces environmental pollution and pesticide residues, improves resource utilization, and balances economic efficiency, environmental friendliness, and agricultural product safety. It is an important technological equipment for modern green planting. Commercially available systems typically consist of a pesticide atomization module containing a pesticide tank, a precision infusion pump, a pneumatic atomizer, and a directional nozzle assembly. This module atomizes the pesticide into droplets of appropriate size and precisely delivers them to the diseased areas of the melon, enabling targeted application and reducing pesticide waste. The droplet recovery module includes a retractable recovery hood, a negative pressure fan, a cyclone separator, a filter, and a recovery liquid storage tank. It collects unattached droplets for recycling, reducing pollution. The auxiliary support module includes a power system, an adjustable-height lightweight frame, and safety protection components, providing support and protection for the device's operation. Through the synergistic effect of these modules, the system improves pesticide utilization, reduces pesticide waste and environmental pollution, and is suitable for large-scale melon cultivation. Some equipment on the market has shortcomings in terms of spray pipe replacement and water leakage at the connection points. When replacing the spray pipe, due to the tight connection of each module and the relatively fixed interface design of some pipelines with components such as atomizers and infusion pumps, the disassembly and installation process is cumbersome and inconvenient. At the same time, if some connections are not properly sealed, water leakage may occur due to long-term pressure or pesticide corrosion, affecting the pesticide delivery efficiency and recovery effect. To address these issues, a precision atomization application and droplet recovery device for bacterial angular leaf spot pesticides for melons is proposed. Utility Model Content

This fixed connection method can ensure the sealing between the connector 61 and the supply tube 5, preventing leakage of the medicine during delivery. A connecting disc 62 is fixedly connected to the outside of the connector 61. The connecting disc 62 provides an installation base for the atomizing mechanism 6, which helps to improve the overall structural stability of the atomizing mechanism 6. An upper half ring 64 is slidably connected to the outside of the connecting disc 62. A rotating block 67 is rotatably connected to the outside of the upper half ring 64. The rotating block 67 can make the upper half ring 64 rotate relative to each other for replacement. The front end of the rotating block 67 is fixedly connected to the lower half ring 66. The fixed connection between the rotating block 67 and the lower half ring 66 ensures that the lower half ring 66 rotates synchronously with the rotating block 67, ensuring the accuracy and stability of the angle adjustment. The lower half ring 66 is internally slidably connected to the connecting disc 63. The sliding connection between the lower half ring 66 and the connecting disc 63 allows the connecting disc 63 to be disassembled. The connecting disc 63 is internally fixedly connected to the atomizing nozzle 65. The connecting disc 63 is externally slidably connected to the inside of the upper half ring 64. There is a sealing rubber between the connecting disc 63 and the upper half ring 64 to prevent accidental leakage of the atomizing mechanism 6 during operation. The bottom of the upper half ring 64 is slidably connected to the top of the lower half ring 66. The sliding connection between the upper half ring 64 and the lower half ring 66 facilitates the opening and closing of both, making it convenient to inspect and replace the components of the atomizing mechanism 6. The lower half ring 66 has an internal sliding connection to a connecting disc 62. The sliding connection between the lower half ring 66 and the connecting disc 62 allows for easy and unobstructed replacement. The external sliding connection of the connecting disc 62 is to the external connection of the connecting disc 63. The sliding fit between the connecting disc 62 and the connecting disc 63 ensures that both are easier to adjust. The upper half ring 64 has an external fixed connection to a pressure locking assembly 68. The pressure locking assembly 68 can firmly lock the upper half ring 64 and the lower half ring 66 after they have been adjusted to their correct positions, preventing them from shifting during application and ensuring the stability of the application. The pressure locking assembly 68 includes an inner rotating block 681, which provides an installation carrier for the pressure locking assembly 68, ensuring that all components can be installed in an orderly manner and function properly. The inner rotating block 681 is externally fixed to the outside of the upper half ring 64. The fixed connection between the inner rotating block 681 and the upper half ring 64 ensures that the pressure lock assembly 68 moves synchronously with the upper half ring 64, ensuring the effective realization of the locking function. The top of the inner rotating block 681 is slidably connected to a second spring 686. The second spring 686 can generate pressure through its own elastic deformation, providing power for the locking of the pressure lock assembly 68 and ensuring the firmness of the lock. The top of the second spring 686 is slidably connected to a washer 684. The washer 684 can evenly distribute the pressure of the second spring 686, avoiding damage due to excessive local force. The top of the washer 684 is slidably connected to a torsion block 683. The torsion block 683 facilitates manual operation by the operator to lock and unlock the pressure lock assembly 68, making the operation more convenient. The internal fixed connection of the torsion block 683 is a connecting post 685, which can transmit the operating force of the torsion block 683, thereby realizing the locking and unlocking action of the pressure lock assembly 68. The internal fixed connection of the connecting post 685 is a blocking block 687, which restricts the relative movement of the upper half ring 64 and the lower half ring 66 to achieve stable locking. The external sliding connection of the connecting post 685 is a limiting block 682, which provides a limiting reference for the blocking block 687, ensuring that the blocking block 687 can be accurately locked into the locking position. The external rotatable connection of the connecting post 685 is inside the inner rotating block 681. The rotatable connection between the connecting post 685 and the inner rotating block 681 allows the torsion block 683 to rotate flexibly, which is convenient for the operator to adjust the state of the pressure lock assembly 68. The bottom of the inner rotating block 681 is slidably connected to the top of the limiting block 682. The sliding cooperation between the inner rotating block 681 and the limiting block 682 ensures that each component of the pressure lock assembly 68 is precisely aligned during the locking process, improving the reliability of the locking. The outside of the limiting block 682 is fixedly connected to the outside of the lower half ring 66. The fixed connection between the limiting block 682 and the lower half ring 66 ensures its positional stability and provides reliable limiting support for the blocking block 687. The top of the blocking block 687 is slidably connected to the bottom of the limiting block 682. The sliding connection between the blocking block 687 and the limiting block 682 allows the two to fit together tightly, effectively limiting the relative movement of the upper half ring 64 and the lower half ring 66, and ensuring the positional stability of the atomizing mechanism 6.

[0011] Reference Figure 1 , Figure 2 and Figure 4 The quick-release locking mechanism 3 includes a slide plate 31, which provides a base for the quick-release locking mechanism 3 to be installed and slid, ensuring that all components can work together to achieve quick locking and disassembly functions. The slide plate 31 is externally slidably connected to the inside of the collection tank 1. The sliding connection between the slide plate 31 and the collection tank 1 allows the quick-release locking mechanism 3 to slide as a whole in the collection tank 1. The slide plate 31 is internally slidably connected to a spring 32, which can generate a restoring force through elastic deformation and automatically engage in the locking position to ensure the stability of the locking state. A locking rod 35 is slidably connected inside the spring 32. The locking rod 35 can be engaged into the collection groove 1 under the action of the spring 32, thereby locking the quick-release locking mechanism 3 and the collection groove 1 to prevent accidental dislodgement during use. The locking rod 35 is slidably connected to the inside of the collection groove 1. The sliding connection between the locking rod 35 and the collection groove 1 ensures that the locking rod 35 is accurately engaged in the locking position, ensuring the reliable locking effect of the quick-release locking mechanism 3. A handle 34 is fixedly connected to the outside of the locking rod 35. The handle 34 provides the operator with a convenient point of force application, making it easy to manually pull the locking rod 35 to unlock, making disassembly more convenient. The handle 34 is externally slidably connected to the inside of the slide plate 31. The sliding connection between the handle 34 and the slide plate 31 restricts the range of movement of the handle 34, ensuring that the operator can apply force stably and avoid slipping during operation. The locking rod 35 is externally fixedly connected to a limiting ring 33. The limiting ring 33 can limit the extension and contraction of the spring 32, prevent the spring 32 from being damaged due to excessive deformation, and at the same time ensure that the force of the spring 32 on the locking rod 35 is stable. The outer end of the spring 32 is fixedly connected to the outside of the limiting ring 33. The fixed connection between the spring 32 and the limiting ring 33 can ensure that the elastic force of the spring 32 is effectively transmitted to the locking rod 35, ensuring the locking force of the locking rod 35. The sliding plate 31 has a positioning protrusion 36 inside, which can be precisely positioned to ensure that it is installed in the correct position and to ensure stable filtration effect. The positioning protrusion 36 is fixedly connected to the filter plate 37 outside. The fixed connection between the positioning protrusion 36 and the filter plate 37 can prevent the filter plate 37 from shaking during use and ensure the filtration effect on collected mist droplets. The limiting ring 33 is externally slidably connected to the inside of the sliding plate 31. The sliding connection between the limiting ring 33 and the sliding plate 31 can limit the movement direction of the locking rod 35 and ensure that the locking rod 35 accurately engages or disengages from the locking position along a straight line. The slide plate 31 is fixedly connected to the outside of the filter plate 37. The fixed connection between the slide plate 31 and the filter plate 37 makes the two form a whole, which makes it easy to move the filter plate 37 by operating the slide plate 31 to achieve quick loading and unloading. The front end of the filter plate 37 is slidably connected to the inside of the collection tank 1. The slidable connection between the filter plate 37 and the collection tank 1 makes it easy to remove or put the filter plate 37 into the collection tank 1, which is convenient for cleaning the filtered impurities and ensuring the purity of the recovered liquid.

[0012] Working principle: When the user needs to disinfect the melon, the twist block 683 rotates, which drives the connecting column 685 to rotate. The connecting column 685 then drives the blocking block 687 to rotate. When the blocking block 687 is vertical, it can pass through the hole reserved by the spring 686. The spring 686 pushes the pad 684 upward, and the pad 684 then drives the twist block 683, causing the twist block 683 to move the connecting column 685. The connecting column 685 then moves the blocking block 687, allowing the blocking block 687 to move out of the restriction block 682. At this time, the upper half ring 64 and the lower half ring 66 can be opened without obstruction, allowing the atomizing nozzle 65 to be replaced. When the correct ring is installed, close the upper half ring 64 and the lower half ring 66. Press the torsion block 683 to move the connecting post 685. The connecting post 685 moves the blocking block 687 through the limiting block 682. Rotate again to make the blocking block 687 horizontal and unable to pass through the limiting block 682, thus achieving quick replacement. The second spring 686 will continuously provide outward rebound force to firmly fix the blocking block 687 at the bottom of the limiting block 682. The surfaces of the first connecting disc 62 and the second connecting disc 63 have sealing rubber sheets, and the interiors of the upper half ring 64 and the lower half ring 66 also have sealing rubber, so that the greater the pressure, the better the sealing effect.

[0013] When the sprayed medicine at the top gathers into droplets, it drips into the inside of the collection tank 1, flows into the water pipe 2 after being filtered by the filter plate 37, and is finally collected. When the filter plate 37 is clogged and needs to be cleaned, pull the handle 34 backward. The handle 34 will drive the locking rod 35 to move, and the locking rod 35 will drive the limiting ring 33 to move. The limiting ring 33 will press the spring 32 backward to store force. At this time, pull the slide plate 31 upward to remove the filter plate 37. The positioning protrusion 36 is used to position and fix the filter plate 37. After cleaning, replace the filter plate 37. Align the positioning protrusion 36 with the groove reserved inside the slide plate 31, slide the slide plate 31 down along the groove reserved inside the collection tank 1, pull it backward again, and after it is fully inserted, release the handle. The spring 32 will rebound and push out, pushing the locking rod 35 out of the inside of the slide plate 31, achieving the effect of quick cleaning and fixing.
