Description

Technical Field

[0001] This utility model relates to the field of mountain tea garden technology, and in particular to a portable vacuum insect suction device for pests in mountain tea gardens. Background Technology

[0002] Mountain tea gardens refer to tea gardens located in mountainous areas at high altitudes, where tea trees that have been planted for a long time are grown. These tea gardens are usually located in mountainous, hilly, or plateau regions because the climate and soil characteristics of these areas are very favorable for the growth of tea trees. The tea trees in mountain tea gardens have usually grown for many years, with dense canopies and deep root systems, and have adapted to the climate and environment of the mountains. Therefore, the components and flavors of the tea are also more unique.

[0003] Meanwhile, traditional tea garden insect-absorbing equipment is quite heavy, generally weighing over 15kg, and some even exceeding 18kg. Operators carrying these devices for extended periods in tea gardens with steep slopes and complex terrain are prone to fatigue, impacting work efficiency, increasing labor intensity, and hindering sustainable operation. Furthermore, traditional insect-absorbing devices often employ fixed modular suction heads, which are limited in style and cannot be flexibly adjusted to different layers of the tea canopy. This makes it difficult to adhere to the undersides of leaves and the interiors of tender shoots, areas where pests hide. For example, when targeting small pests such as tea lace bugs, green mirid bugs, and tea geometrid moth larvae that prefer to hide on the undersides of leaves or in crevices of branches, traditional modular suction heads often fail to achieve effective suction due to their small contact area and poor sealing, resulting in low capture efficiency and severely impacting overall insect control effectiveness. Utility Model Content

[0004] To overcome the problems of traditional equipment being heavy and easily causing operator fatigue, and fixed modular suction heads not being able to fit well into different layers of the tea tree canopy, this utility model provides a portable vacuum insect suction device for pests in mountain tea gardens.

[0005] The technical solution is as follows: A portable vacuum insect suction device for pests in mountain tea gardens includes an insect suction frame; a transparent insect collection box is provided at the lower end of the insect suction frame for real-time observation of insect collection and determination of whether cleaning is necessary. The transparent insect collection box is fastened to the insect suction frame by a buckle. An air outlet is fixedly connected to the upper end of one side of the insect suction frame. A mounting frame is provided in a ring on the upper surface of the end of the insect suction frame near the air outlet. A sealing sleeve is fastened to the inside of the mounting frame. A negative pressure blower is fixedly connected to the upper end of the sealing sleeve. A sleeve is fixedly connected to the upper end of the other side of the insect suction frame. A filter screen is provided between the air outlet and the insect suction frame to separate the sucked-in air from the insects and to prevent the insects from escaping.

[0006] Furthermore, a sleeve is fitted on the outer side of the top of the sleeve, and a telescopic hose is fixedly connected to the front end of the sleeve.

[0007] Furthermore, the telescopic flexible tube is equipped with a suction tube at its tip, and a modular suction head is installed at the tip of the suction tube.

[0008] Furthermore, the modular suction head and the insect suction tube are fastened together by a fastening frame, and the surface of the modular suction head is covered with an adhesive sealing strip.

[0009] Furthermore, the negative pressure blower has a linear wiring on its outer side, with a handle fixedly connected to the top of the wiring, and a power display screen installed on the outside of the handle.

[0010] Furthermore, a threaded frame is installed around the upper end of the side of the insect-sucking frame near the sleeve, and a threaded cap is threadedly connected to the outside of the threaded frame.

[0011] Furthermore, a handle is fixedly connected to the center of the upper end of the fluke frame, and two sets of fixing brackets are symmetrically installed at the rear end of the top of the fluke frame.

[0012] Furthermore, a carrying strap is vertically installed on the outside of the fixing frame, and a sponge pad is wrapped around the center of the rear surface of the insect-absorbing frame.

[0013] The beneficial effects are as follows: This utility model achieves powerful suction by generating a negative pressure blower, which can effectively suck pests away from tea trees. The filter design ensures that the sucked-in pests will not escape, thereby improving capture efficiency. The transparent insect collection box allows users to observe the collected pests in real time, so as to determine in a timely manner whether the insect collection box needs to be cleaned, ensuring the continuous and efficient operation of the equipment. Equipped with a telescopic hose and an adjustable-angle sleeve design, the device can adapt to the needs of tea tree operations at different heights and positions. The sponge pad covering the center of the rear surface of the insect suction frame increases the comfort when carrying it and reduces the physical burden on the operator during long-term operation.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Among the currently discovered feasible technologies, the following are described:

[0022] Mountain tea gardens refer to tea-growing areas established in mountainous regions with high altitudes and favorable ecological conditions. These tea gardens are mostly distributed in hilly, mountainous, or plateau areas with significant topographical variations. Their superior natural environment includes a humid and mild climate, large diurnal temperature range, frequent cloud cover, high air humidity, and acidic red or yellow soils, or humus-rich mountain soils, making them highly suitable for tea tree growth. Due to their long-term exposure to the natural ecological environment, the tea trees in mountain tea gardens often have a long history of cultivation, with many gardens having been cultivated for decades or even centuries. Through years of natural growth and artificial pruning, the tea trees have developed a dense canopy structure and a deep root system, possessing strong resistance and adaptability, and better able to resist the effects of pests, diseases, and adverse climatic conditions. Furthermore, mountain tea gardens are usually located in areas with inconvenient transportation and minimal human disturbance, maintaining a well-preserved ecological environment with low pollution levels. This results in teas with unique characteristics in quality, aroma, and flavor, and rich internal nutrients. The content of amino acids, tea polyphenols, and aromatic substances in mountain tea gardens is generally higher than in tea gardens in flat areas. As a result, the tea produced has a more mellow taste and a longer-lasting sweet aftertaste, giving it higher market value and brand influence. However, due to the complex terrain, steep slopes, narrow spaces, and limited access in mountain tea gardens, traditional agricultural machinery is difficult to operate, especially in pest and disease control. For example, conventional spraying equipment is inconvenient to operate and inefficient; while physical control equipment such as insect suction machines are limited in their application in mountainous environments due to their large weight, poor mobility, and insufficient adaptability of suction heads. Therefore, developing a lightweight, modular, portable vacuum insect suction device that is easy to carry and operate and can flexibly adapt to different tea tree structures is of great significance for achieving green pest control in tea gardens, improving operational efficiency, reducing labor intensity, and promoting the mechanization of tea gardens.

[0023] Meanwhile, traditional tea garden insect-absorbing equipment generally suffers from a bulky overall structure, typically weighing over 15 kilograms, with some even exceeding 18 kilograms. This undoubtedly adds a significant physical burden for users who need to move and operate for extended periods in mountainous tea gardens with steep slopes, complex terrain, and narrow access routes. In actual use, operators not only have to overcome the weight of the equipment itself but also the difficulty of walking on uneven ground and the need to frequently adjust their working posture. This continuous labor intensity easily leads to physical fatigue, reduces work efficiency, and affects the continuity of operations, making it difficult to meet the actual needs of large-scale and sustainable tea garden management. Furthermore, from the perspective of equipment functional design, traditional insect-absorbing devices mostly adopt fixed or modular suction head structures with a single style, lacking adaptation and optimization for different tea tree canopy structures and pest habitats. The suction head has a fixed shape and non-adjustable angle, making it impossible to flexibly fit different layers of the tea tree canopy, especially when facing the tender shoots in the upper and middle parts of the tea tree, the back of leaves, and the crevices of branches where pests hide and inhabit, often making it difficult to achieve effective coverage. Taking typical tea garden pests such as the tea lace bug, green mirid bug, and tea geometrid moth larvae as examples, these pests are tiny and often hide on the underside of leaves or in the foliage of tea trees, placing high demands on the adsorption efficiency and sealing performance of the suction device. However, traditional suction heads, due to their limited contact area and poor sealing with tea tree branches and leaves, struggle to create a stable negative pressure environment, leading to airflow dispersion and weakened adsorption, thus significantly reducing the capture rate of target pests. Furthermore, because the suction head cannot fit tightly against the tea tree, air leakage easily occurs during actual operation, causing localized negative pressure attenuation. This not only affects the effectiveness of a single operation but may also cause insects to escape, reducing overall pest control efficiency. This deficiency is particularly prominent in densely planted tea gardens with complex intertwined branches and leaves, severely restricting the widespread application of physical control methods in mountainous tea gardens. Therefore, a new type of suction device that can be flexibly adjusted according to the actual terrain and tea tree structure, possessing good sealing performance and high adsorption capacity, is needed to improve the mechanization level and green control capabilities of pest management in mountainous tea gardens.

[0024] The new portable vacuum insect suction device offers significant improvements and advantages in several aspects, making it particularly suitable for addressing the shortcomings of traditional equipment in mountainous tea gardens. Firstly, by adopting lightweight materials such as carbon fiber and optimizing the design, the overall weight of the machine is significantly reduced to less than 8 kg, greatly reducing the physical burden on the operator and making long-term operation more feasible. This improves work efficiency while reducing labor intensity, facilitating sustainable tea garden management. Furthermore, the device features a modular suction head design, offering a variety of styles including flat wide-mouth, trumpet-shaped round mouth, and flat round mouth. All suction heads are adjustable from 0° to 90°, flexibly adapting to different layers of the tea canopy. It effectively covers and treats pests in various locations, including the tender shoots on the upper part of the tea tree, the undersides of leaves, and crevices in branches. This design significantly enhances the suction effect, ensuring a high capture rate and effectively improving overall insect control, especially for smaller pests that prefer to hide on the undersides of leaves or in crevices, such as tea lace bugs, green mirid bugs, and tea geometrid moth larvae.

[0025] like Figures 1-5 As shown, a portable vacuum insect suction device for pests in mountain tea gardens includes an insect suction frame 1; a transparent insect collection box 4 is provided at the lower end of the insect suction frame 1 for real-time observation of insect collection and determination of whether cleaning is necessary. The transparent insect collection box 4 is fastened to the insect suction frame 1 by a buckle. An air outlet 9 is fixedly connected to the upper end of one side of the insect suction frame 1. An installation frame 8 is provided in a ring on the upper surface of the end of the insect suction frame 1 near the air outlet 9. A sealing sleeve 13 is fastened to the inside of the installation frame 8. A negative pressure blower 12 is fixedly connected to the upper end of the sealing sleeve 13. A sleeve frame 10 is fixedly connected to the upper end of the other side of the insect suction frame 1. A filter screen 11 is provided between the air outlet 9 and the insect suction frame 1 for separating the sucked air from the insects and preventing the insects from escaping.

[0026] A sleeve 17 is fitted on the outer side of the top of the sleeve 10. A telescopic hose 18 is fixedly connected to the front end of the sleeve 17 to improve the flexibility of insect suction operations and adapt to tea trees at different angles and heights. A suction tube 19 is provided at the top of the telescopic hose 18. A modular suction head 21 is installed at the top of the suction tube 19 to ensure the stability of the insect suction path structure and improve the accuracy of operation. The modular suction head 21 and the suction tube 19 are fastened together by a fastening frame 20. The surface of the modular suction head 21 is covered with a glue sealing strip 22 to achieve quick replacement and good sealing, thereby enhancing the insect suction efficiency and applicability.

[0027] When the equipment is turned on, the negative pressure blower 12 starts to operate. The negative pressure blower 12 is fixed to the upper end of the sealing sleeve 13, and the sealing sleeve 13 is set in a ring on the upper surface of the insect suction frame 1 near the air outlet 9 through the mounting bracket 8. The negative pressure blower 12 generates a strong suction force, which is transmitted to the suction head through the internal channel of the insect suction frame 1. The suction force is transmitted to the modular suction head 21 through the telescopic hose 18 and the insect suction hard tube 19. The operator brings the suction head close to the position of the pest on the tea tree. Since the suction head and the insect suction hard tube 19 are connected by the fastening bracket 20, and the surface of the suction head is covered with a rubber sealing strip 22, this ensures good sealing and prevents air leakage, thereby enhancing the suction efficiency. Multiple suction head styles + adjustable suction head angle + hose pressure-resistant structure can meet the operation of mountain tea gardens with a slope of ≤35°. The pests are strongly sucked in and enter the interior of the insect suction frame 1 through the insect suction hard tube 19 and telescopic hose 18. After the sucked-in air carries the pests into the insect suction frame 1, it first passes through the filter screen 11. The filter 11 is located between the air outlet 9 and the insect suction frame 1. It separates the intake air from the pests, preventing the pests from escaping from the air outlet. The pests intercepted by the filter 11 fall into the transparent insect collection box 4. The transparent insect collection box 4 is located at the lower end of the insect suction frame 1, allowing users to observe the insect collection in real time and determine in a timely manner whether the collection box needs to be cleaned.

[0028] Please see Figures 3-4 The negative pressure blower 12 has a linear circuit 14 on its outer side. A handle 15 is fixedly connected to the top of the circuit 14. A power display screen 16 is installed on the outer side of the handle 15, which makes it convenient for users to keep track of the power status of the equipment and improves the ease of operation and controllability. A threaded frame 7 is installed around the upper end of the side of the suction frame 1 near the sleeve 10. A threaded cap 5 is threadedly connected to the outer side of the threaded frame 7, which can adjust and fix the angle of the hose, enhancing the stability and adaptability of the device. A handle 6 is fixedly connected to the center of the upper end of the suction frame 1. Two sets of fixed frames 3 are symmetrically installed at the top and rear end of the suction frame 1, providing a convenient hand-held operation method and providing stable support for the installation of the carrying strap 2. The carrying strap 2 is vertically installed on the outer side of the fixed frame 3. A sponge pad 23 is covered in the center of the rear surface of the suction frame 1 to reduce the carrying pressure and improve the comfort and ergonomic design of long-term operation.

[0029] When the equipment is started, the negative pressure blower 12 begins to work, generating the required suction. Line 14 extends linearly from the outside of the negative pressure blower 12 to the top, where a handle 15 is fixedly connected. The handle 15 is designed for user convenience, allowing the user to easily carry and control the equipment. A battery display screen 16 is installed on the outside of the handle 15, which can display the remaining battery power in real time, allowing the user to monitor the equipment's working status at any time and ensure that work is not interrupted due to insufficient power. A handle 6 is located at the center of the upper end of the suction frame 1, making it easy for the user to hold and operate the equipment, especially when rapid movement or precise positioning is required. Two sets of fixing frames 3 are symmetrically installed at the top and rear end of the suction frame 1. These fixing frames 3 not only provide a convenient hand-held operation method for the user but also provide stable support for the installation of the carrying strap 2, ensuring balance and stability when carrying the equipment. The carrying strap 2 is vertically installed on the outside of the fixing frames 3. When long-term, large-area pest control work in tea gardens is required, the user can use the carrying strap 2 to distribute the weight of the equipment and reduce arm pressure.
