Description

Technical Field

[0001] This utility model relates to the field of forestry technology, and in particular to a protective sleeve for preventing damage to fruit trees. Background Technology

[0002] The forestry industry refers to a comprehensive industrial system centered on forest resources, encompassing the entire chain of forest cultivation, management, harvesting, processing, manufacturing, and ecological protection. Its resource scope includes not only forestry resources such as arbor forests and shrub forests formed through artificial afforestation and natural forest maintenance, but also associated resources such as understory economic crops and wild animals. The forestry industry possesses both economic and ecological attributes. It provides key raw materials for industries such as construction, furniture, and papermaking, supporting national economic development. Furthermore, through the forest ecosystem, it plays an important role in regulating climate, purifying the environment, and conserving water resources. It is a crucial industrial sector for achieving coordinated ecological protection and economic development. However, harsh winter conditions such as low temperatures and snowstorms easily lead to frost damage to fruit tree trunks and bark. During fruit growth, fruits are susceptible to damage from birds, insect infestations, wind, rain, hail, and bark friction. Traditional protection methods suffer from poor adaptability, impact on fruit development, or cumbersome operation. Therefore, a protective sleeve for fruit trees is particularly needed.

[0003] However, traditional fruit tree protection bags require the fruit to be completely stuffed into the bag and then secured with a rope, which is time-consuming. In addition, the protective bags are mostly made of a single film or ordinary cloth bag, which is not very protective against birds pecking at the fruit or insects attacking it. The film material is easily scratched by branches or cracked by hail, while the cloth bag material cannot prevent small pests from crawling in and eating the fruit. Utility Model Content

A wedge-shaped anti-detachment block is connected to the outer side of the limit plate. An anti-detachment groove is provided on the inner side of the telescopic rope.

[0006] Preferably, the vent holes are evenly distributed in a matrix on the side wall of the protective sleeve, and the line connecting the centers of adjacent vent holes is parallel to the axis of the protective sleeve.

[0007] Preferably, the edge of the one-way breathable membrane is fixedly connected to the inner wall edge of the vent hole by heat pressing, and the one-way breathable membrane completely covers the inner opening of the vent hole.

[0008] Preferably, the insect-proof net and the non-woven buffer layer are fixedly connected by stitches, with the stitches evenly distributed along the circumference of the protective cover, and the positions of the stitches and the ventilation holes are staggered.

[0009] Preferably, the first conduit and the second conduit are symmetrically distributed about the axis of the protective sleeve, and the axes of the first conduit and the second conduit are parallel to the axis of the protective sleeve.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a protective cover for fruit trees, including a protective cover 1, with ventilation holes 2 on the surface of the protective cover 1, a one-way breathable membrane 3 on the inner wall surface of the ventilation holes 2, an insect-proof net 4 connected to the inner wall of the protective cover 1, a non-woven fabric buffer layer 5 connected to the inner wall of the insect-proof net 4, and a telescopic adjustment component 6 on the upper outer wall of the protective cover 1. The telescopic adjustment component 6 includes a first conduit 601 connected to the outer side of the protective sleeve 1 near the bag opening. A second conduit 602 is also connected to the outer side of the protective sleeve 1. A telescopic rope 603 is connected between the first and second conduits 601 and 602. A movable plate 604 is movably connected to the outer wall of the other end of the telescopic rope 603. A telescopic groove 605 is provided inside the movable plate 604. A locking spring 606 is connected to the inner end of the telescopic groove 605. A limiting plate 607 is connected to the other end of the locking spring 606. A wedge-shaped anti-detachment block 608 is connected to the outer side of the limiting plate 607. An anti-detachment slot 609 is provided on the inner side of the telescopic rope 603. With the telescopic adjustment component 6, when in use, the fruit is first placed inside the protective sleeve 1, so that the insect net 4 and the non-woven fabric... The buffer layer 5 adheres to the fruit surface. Then, the telescopic adjustment assembly 6 is operated to adjust the bag opening. Holding the movable plate 604, the telescopic rope 603 is pulled away from the protective sleeve 1. The telescopic rope 603 slides along the inner walls of the first conduit 601 and the second conduit 602, causing the fabric at the bag opening of the protective sleeve 1 to contract. Because the first conduit 601 and the second conduit 602 are symmetrically distributed, the force on each side of the bag opening is balanced when the telescopic rope 603 is pulled, preventing the bag opening from shifting or wrinkling. During the pulling process, the anti-detachment groove 609 on the inner side of the telescopic rope 603 contacts the wedge-shaped anti-detachment block 608 in the telescopic groove 605 of the movable plate 604. The wedge-shaped anti-detachment block 608 is squeezed into the telescopic groove 605 by the anti-detachment groove 609, pushing the limiting plate 607 to compress the locking spring 606, allowing the telescopic rope 603 to move smoothly. When the bag opening contracts to a tightness that fits snugly against the fruit stem and prevents the fruit from swaying, pull the telescopic rope 603. The engaging spring 606 releases its elastic potential energy, pushing the limiting plate 607 and the wedge-shaped anti-detachment block 608 back to their original positions. The wedge-shaped anti-detachment block 608 then engages in the corresponding anti-detachment groove 609. Utilizing the one-way limiting characteristic of the wedge structure, the telescopic rope 603 is prevented from sliding backward, thus securing the bag opening. If the fruit grows and its size increases, requiring loosening of the bag opening, no additional pressing is needed. Simply pull the movable plate 604 in the opposite direction towards the protective sleeve 1. At this time, the movable plate 604 causes the wedge-shaped anti-detachment block 608 in the telescopic groove 605 to move synchronously. The inclined surface of the wedge-shaped anti-detachment block 608 contacts and is compressed against the groove wall of the anti-detachment groove 609 inside the telescopic rope 603. The squeezing force causes the wedge-shaped anti-detachment block 608 to retract into the telescopic groove 605, which in turn pushes the limiting plate 607 to compress the locking spring 606. As the movable plate 604 continues to pull in the opposite direction, the wedge-shaped anti-detachment block 608 slides out of its original slot along the inclined surface of the anti-detachment groove 609. Under the elastic rebound of the protective sleeve 1 bag opening fabric, the telescopic rope 603 retracts along the first conduit 601 and the second conduit 602 towards the bag opening, and the bag opening gradually loosens. When the tightness of the bag opening is suitable for the current size of the fruit, the reverse pulling of the movable plate 604 stops, and the locking spring 606 immediately releases its elastic potential energy, pushing the limiting plate 607 and the wedge-shaped anti-detachment block 608 to reset. The wedge-shaped anti-detachment block 608 then engages in the anti-detachment groove 609 corresponding to its current position, completing the re-fixation of the bag opening after it has loosened.Throughout the process, the first conduit 601 and the second conduit 602 consistently provide a stable sliding path for the telescopic rope 603, preventing rope deviation or wear. The design that allows loosening by pulling in the opposite direction greatly simplifies operation. Multiple sets of equally spaced anti-detachment slots 609 ensure adjustment precision, allowing the components to adapt to fruit growth dynamics while maintaining reliable protection for the fruit at all times.

[0018] Furthermore, the ventilation holes 2 are evenly distributed in a matrix on the side wall of the protective sleeve 1, and the center line connecting adjacent ventilation holes 2 is parallel to the axis of the protective sleeve 1. Through the setting of ventilation holes 2, the matrix-like even distribution can make the air permeability rate of each area inside the protective sleeve 1 consistent, avoiding the accumulation of moisture due to insufficient air permeability in some areas, which can cause fruit mold. At the same time, the design of the center line parallel to the axis of the protective sleeve 1 can reduce the amount of rainwater and dust from the outside falling directly into the interior of the protective sleeve 1 along the ventilation holes 2, which can both ensure the amount of air permeability required for the fruit to breathe and reduce the pollution and damage of impurities to the fruit skin.

[0019] Furthermore, the edge of the one-way breathable membrane 3 is fixedly connected to the inner wall edge of the vent 2 by heat pressing, and the one-way breathable membrane 3 completely covers the inner opening of the vent 2. Through the setting of the one-way breathable membrane 3, the heat pressing method can ensure that the one-way breathable membrane 3 and the vent 2 are firmly connected, avoiding detachment and failure during use. The one-way breathable structure that completely covers the opening allows the moisture generated by the fruit's respiration inside the protective cover 1 to be discharged in one direction, while blocking external rainwater and dew from seeping in through the vent 2, effectively balancing the needs for breathability and moisture prevention, and preventing the formation of a high temperature and high humidity environment inside the cover from affecting the quality of the fruit.

[0020] Furthermore, the insect-proof net 4 and the non-woven fabric buffer layer 5 are fixedly connected by stitches. The stitches are evenly distributed along the circumference of the protective sleeve 1, and the positions of the stitches are staggered from the positions of the ventilation holes 2. With the setting of the insect-proof net 4 and the non-woven fabric buffer layer 5, the insect-proof net 4 can prevent aphids, fruit flies and other small pests from entering the protective sleeve 1 and eating the fruit. The non-woven fabric buffer layer 5 can buffer the friction between the fruit and the inner wall of the protective sleeve 1 when it is blown by the wind, avoiding scratches on the skin. The stitches ensure that the two fit tightly and do not slip. The evenly distributed circumference ensures that the force is evenly distributed. The staggered design of the ventilation holes 2 avoids the stitches from blocking the ventilation channels, so that the protective and ventilation functions do not interfere with each other.

[0021] Furthermore, the first conduit 601 and the second conduit 602 are symmetrically distributed about the axis of the protective sleeve 1, and the axes of the first conduit 601 and the second conduit 602 are parallel to the axis of the protective sleeve 1. Through the arrangement of the first conduit 601 and the second conduit 602, the symmetrical distribution allows the bag opening to contract evenly on all sides when the telescopic rope 603 pulls the bag opening of the protective sleeve 1, avoiding bag opening deviation and wrinkles caused by unilateral force, which would prevent it from tightly fitting the fruit stem. The axis of the conduit parallel to the axis of the protective sleeve 1 can guide the telescopic rope 603 to slide in a straight line, reducing frictional loss between the rope and the inner wall of the conduit, and ensuring a smooth and stable bag opening adjustment process.

[0022] Furthermore, one side surface of the movable plate 604 is provided with a rope hole adapted to the telescopic rope 603. The rope hole is connected to the telescopic groove 605, and the axis of the rope hole is perpendicular to the axis of the telescopic groove 605. Through the setting of the movable plate 604, the rope hole adapted to the telescopic rope 603 can guide the rope to accurately enter the telescopic groove 605, avoiding rope deviation that would cause adjustment failure. The vertical axis design allows the pulling direction of the telescopic rope 603 to match the engaging direction of the wedge-shaped anti-detachment block 608, so that when the movable plate 604 is pulled, the wedge-shaped anti-detachment block 608 can smoothly engage with the anti-detachment slot 609, which facilitates the adjustment of the bag opening tightness and ensures stable engagement after adjustment.

[0023] Furthermore, the end of the wedge-shaped anti-drop block 608 furthest from the limiting plate 607 is chamfered, and the outer wall size of the wedge-shaped anti-drop block 608 matches the inner wall size of the anti-drop groove 609. Through the setting of the wedge-shaped anti-drop block 608 and the anti-drop groove 609, the chamfered design can reduce the frictional resistance when the wedge-shaped anti-drop block 608 and the anti-drop groove 609 are engaged or disengaged, making bag opening adjustment easier. The matching size design allows the wedge-shaped anti-drop block 608 to be fully engaged in the anti-drop groove 609, avoiding the loosening of the telescopic rope 603 due to excessive gap after adjustment, ensuring the tightness of the bag opening is stable and adapting to the size requirements of different fruit growth stages.

[0024] Working principle: First, the fruit to be protected is placed into the protective sleeve 1 through the bag opening, allowing the insect-proof mesh 4 on the inner wall and the non-woven cushioning layer 5 to naturally adhere to the fruit surface. Then, the bag opening is fixed by the telescopic adjustment component 6. Holding the movable plate 604, the telescopic rope 603 is pulled away from the protective sleeve 1. The telescopic rope 603 slides smoothly along the symmetrically distributed first tube 601 and second tube 602 of the protective sleeve 1, causing the fabric at the bag opening to shrink evenly, avoiding displacement or wrinkles caused by unilateral force. During the pulling process, the telescopic rope 603... The anti-drop groove 609 on the side presses against the wedge-shaped anti-drop block 608 in the telescopic groove 605 of the movable plate 604, causing the wedge-shaped anti-drop block 608 to compress the locking spring 606 and retract into the groove, ensuring the smooth pulling of the telescopic rope 603. When the bag opening retracts to a tight fit against the fruit stem with no room for fruit movement, the pulling stops, the locking spring 606 resets, and pushes the wedge-shaped anti-drop block 608 into the corresponding anti-drop groove 609, achieving a stable fixation of the bag opening. During fruit growth, the matrix-like evenly distributed ventilation holes 2 on the side wall of the protective sleeve 1 ensure uniform ventilation in all areas inside the sleeve, preventing... Moisture buildup is addressed by a one-way breathable membrane 3, which is heat-pressed to the inner wall of the ventilation holes 2 and completely covers the openings. This allows moisture generated by the fruit's respiration to escape in one direction while preventing rainwater and dew from seeping in, balancing breathability and moisture control. The inner wall insect-proof mesh 4 and the non-woven cushioning layer 5 are secured with evenly spaced circumferential stitching. The insect-proof mesh 4 prevents aphids, fruit flies, and other pests from entering and feeding on the fruit, while the non-woven cushioning layer 5 cushions the fruit from friction against the bag wall when it is blown or shaken by the wind, preventing scratches on the skin without affecting breathability. When the fruit grows and the size increases, requiring the bag opening to be loosened, no additional operation is needed. Simply pull the movable plate 604 in the opposite direction towards the protective sleeve 1. The wedge-shaped anti-drop block 608 is squeezed and contracted by the anti-drop groove 609. The telescopic rope 603 retracts under the elastic rebound of the bag opening fabric, and the bag opening gradually loosens. After adjusting to fit the current size of the fruit, the wedge-shaped anti-drop block 608 is locked back into the anti-drop groove 609 to complete the fixation. Throughout the process, all components work together to achieve comprehensive protection against damage to the fruit and dynamically adapt to the growth of the fruit, ensuring the quality and safety of the fruit. This completes the use of a fruit tree fruit damage protection sleeve.
