Description

Technical Field

[0001] The invention relates to the technical field of fruit tree insect-proof devices, and in particular to a stable support for a single fruit tree with an insect-proof net covering the entire tree. Background Art

[0002] The single-tree insect-proof net for fruit trees is a physical insect-proof device specially designed for fruit trees. It is mainly used to protect the entire tree by covering it with insect-proof nets, avoiding pest invasion and reducing the use of pesticides. It is suitable for fruit trees such as peach, plum, guava, bayberry, citrus, loquat, cherry, persimmon and pear. Covering the fruit before it matures can block the spread of pests, reduce fruit drop and pesticide residues, and improve fruit quality and yield.

[0003] Among the existing fruit tree insect prevention products, the orchard insect and windproof net includes an insect and windproof net, a guide trough and an anchoring system. The insect and windproof net is densely woven on the upper part and sparsely woven on the lower part, forming a wind pressure gradient and having an insect-proof effect; the guide trough adopts V-shaped raised stripes to guide the airflow to turn; the anchoring system is a combination of ground nails + wind-resistant ropes. This product dissipates wind energy step by step through the density gradient and combines with the guide trough to destroy the vortex structure, so as to improve the firmness and wind resistance of the wind and insect net.

[0004] In actual use, when fruit trees sway due to wind or the weight of the fruit, the aforementioned method of locking the rod sleeves at both ends and the L-shaped steel pipe through the fixing groove will cause the swaying of the fruit tree to cause excessive pulling force on the bracket, resulting in the mesh tearing or unhooking at the seams. Therefore, it is necessary to propose a stable bracket covered with insect-proof netting for individual fruit trees. This bracket has the ability to deform, thereby improving the bracket's durability and environmental adaptability while maintaining high insect-proofing efficiency. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a stable bracket for covering the entire fruit tree with an insect-proof net. Through the lateral dynamic telescopic mechanism of the covering adjustment rod and the pressure sensing linkage control system, the bracket can realize adaptive stress release of the fruit tree in response to the shaking of the fruit tree, effectively solving the problems of mesh tearing and seam unhooking caused by hard pulling of traditional fixed insect-proof nets.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a stable support for a single fruit tree with an insect-proof net covering the entire tree, comprising an insect-proof net, a support fitted inside the insect-proof net, the support comprising a central rod and a plurality of edge rods, a joint welded to the top of the central rod, a plurality of covering adjustment rods uniformly and fixedly connected to the side walls of the joint along its circumference, the covering adjustment rods each comprising a transverse telescopic rod and a hanging rod tube, one end of the transverse telescopic rod being fixedly connected to the joint, the hanging rod tube being slidably connected to the transverse telescopic rod, each covering adjustment rod being provided with an elastic reset assembly, and a plurality of hook assemblies for hooking and connecting to the corresponding edge rods being provided at one end of the hanging rod tube away from the transverse telescopic rod;

[0007] A controller is configured in the joint, and each coverage adjustment rod is also provided with a sliding limit assembly for unlocking and locking the sliding adjustment of the coverage range. Each edge rod is provided with a pressure sensor. Several pressure sensors and sliding limit assemblies are connected to the controller signal. When the fruit tree shakes, any pressure sensor will detect the pressure signal and unlock all the sliding limit assemblies, so as to dynamically adjust the coverage range according to the shaking of the fruit tree while meeting the stability effect of normal use.

[0008] The technical principles of this solution are as follows: The design of the central rod and several edge rods fully considers the shape and size of the fruit tree canopy, ensuring a close fit and providing comprehensive insect protection for the fruit trees. The lateral telescopic rods can flexibly slide within the hanging rod tube to effectively adjust the coverage range according to different usage scenarios and the actual needs of the fruit tree canopy, ensuring that the coverage requirements of the fruit tree canopy are accurately met during the adjustment process. Furthermore, the design of the elastic reset component allows the structure to quickly return to a stable state after the wind force dissipates, thanks to its elastic properties, to avoid shaking or instability.

[0009] The pressure sensor design enables intelligent, adaptive expansion and contraction of the entire insect control coverage area. The pressure sensor senses in real time the pressure changes caused by the tree's swaying. When the tree sways due to natural factors such as wind, the edge rods are subjected to corresponding pressure. The pressure sensor accurately transmits these pressure signals to the controller, which unlocks the sliding limiter assembly, allowing the coverage adjustment rods to expand and contract according to the tree's swaying.

[0010] The above scheme has the following beneficial effects:

[0011] 1. In the traditional fruit tree insect-proof net covering method, the rigid support lacks flexibility and is difficult to cope with the shaking of the fruit trees. When the fruit trees are affected by factors such as wind in the natural environment and shake, the rigid support cannot make corresponding adjustments, which causes the insect-proof net to be subjected to local pulling force. This solution uses the sliding displacement design of the covering adjustment rod. When the fruit tree shakes, the covering adjustment rod can slide under the action of the pressure sensing linkage control logic, effectively absorbing the kinetic energy generated by the shaking of the fruit tree, avoiding excessive local pulling of the insect-proof net, and allowing the insect-proof net to maintain a relatively stable state when facing the shaking of the fruit tree, thereby improving the tear resistance of the insect-proof net, extending the service life of the insect-proof net, and ensuring that the insect-proof net can continue to effectively provide insect protection for the fruit trees.

[0012] 2. The design of the pressure sensor combined with the controller enables the expansion and contraction adjustment of the insect-proof range to have the efficiency of intelligent opening and closing. By real-time monitoring of the swing amplitude of the fruit trees, when the swing amplitude of the fruit trees is large, it means that they may be affected by natural factors such as strong winds. The pressure sensing system will quickly transmit this information to the controller and trigger the dynamic adjustment mechanism of the coverage range. This design can not only ensure the windproof stability of the bracket in windy weather, but also maintain the insect-proof sealing of the insect-proof net under normal circumstances, achieving a balance between windproof stability and insect-proof sealing requirements, and making the entire bracket have stronger environmental adaptability.

[0013] 3. The combination of a hook assembly and an elastic reset mechanism significantly facilitates operation and maintenance. The hook assembly securely fastens the insect screen to the bracket, while the elastic reset mechanism allows the cover adjustment lever to self-reset. Even in conditions of frequent natural disturbances, the bracket remains stable, ensuring the proper operation of the insect screen and enhancing the ease of operation and maintenance of the entire system.

[0014] Furthermore, a humidity sensor is fixedly connected to the main rod, and the humidity sensor is connected to the controller signal.

[0015] Beneficial Effects: Through the linkage between the humidity sensor and the controller, the humidity sensor can accurately sense the humidity inside the insect screen. When the humidity inside the insect screen is detected to be excessively high, the controller automatically triggers the coverage expansion mechanism upon receiving the signal. By adjusting the sliding limiter assembly to adjust the length of the coverage adjustment rod, the coverage of the insect screen is expanded, air circulation is increased, and internal humidity is reduced. This not only ensures the insect screen's effectiveness, but also creates a suitable growth environment for fruit trees. This effectively addresses the increased risk of fungal diseases caused by closed coverage, achieving a balance between insect control effectiveness and the healthy growth of fruit trees.

[0016] Furthermore, the elastic reset assembly includes a reset spring, and both ends of the reset spring are fixedly connected to the corresponding transverse telescopic rod and hanging rod tube respectively.

[0017] Beneficial Effects: The return spring design enables the coverage adjustment rod to automatically return to its original position. The spring's elastic force allows the coverage adjustment rod to quickly and accurately return to its initial position after wind disturbances. This automatic return function enhances the support system's structural resilience after dynamic adjustments, preventing mechanical fatigue caused by frequent expansion and contraction, extending the support system's service life, and improving the stability and reliability of the entire support.

[0018] Furthermore, the edge rods include arc rods and edge ground rods from top to bottom, the top ends of the edge ground rods are hinged to the arc rods, and the arc rods are detachably connected to the corresponding hanging rod tubes through hook assemblies.

[0019] Beneficial Effects: The articulated structure of the curved rod and the edge ground rod enables multi-angle adjustment, allowing the edge rod to rotate and adjust at different angles while simultaneously adapting to the telescopic movement of the cover adjustment rod. Furthermore, when faced with complex terrain, fruit farmers can adjust the angle of the edge rod based on the undulations of the terrain, ensuring that the entire support structure can be securely installed on the ground. Furthermore, for irregular tree crowns, the telescopic movement of the cover adjustment rod and the multi-angle adjustment of the edge rod work together to allow the support to better conform to the shape of the tree crown, improving the support's adaptability to complex terrain and irregular tree crowns, and providing more comprehensive and effective insect protection for fruit trees.

[0020] Furthermore, the hooking components all include a hanging rod block fixedly connected to the corresponding hanging rod tube, and a hanging rod groove of a 'U'-shaped structure is opened on the hanging rod block. The top end of the arc rod is fixedly connected to a through hanging rod, and the through hanging rod vertically passes through the top end of the arc rod, and the shape of the through hanging rod corresponds to the shape of the hanging rod groove.

[0021] Beneficial effects: Through the design of the hanging rod groove and the through-hanging rod, tool-free quick assembly is achieved. The hanging rod groove and the through-hanging rod fit together. Fruit farmers only need to simply insert the through-hanging rod into the hanging rod groove to complete the assembly process. This design effectively solves the technical defects of traditional bracket disassembly that is time-consuming and easy to loosen, improves the installation and disassembly efficiency of the bracket, and saves manpower and time costs.

[0022] Furthermore, the sliding limit assembly includes a magnet ring fixedly connected to the connection between the corresponding transverse telescopic rod and the corresponding hanging rod tube, the inner side wall of the magnet ring is in contact with the outer wall of the corresponding transverse telescopic rod, and the outer side of the magnet ring is fixedly connected to an electromagnetic coil, which is electrically connected to the controller.

[0023] Beneficial Effects: The magnetically controlled limit system utilizes magnetic force regulation between an electromagnetic coil and a magnet ring to achieve intelligent locking of the sliding limit assembly. The electromagnetic coil is designed to generate a controllable magnetic force, which interacts with the magnet ring. By varying the magnitude and direction of the magnetic force, the system controls the locking and unlocking of the hanging rod and the horizontal telescopic rod, avoiding the mechanical wear caused by friction and collision in traditional mechanical limit systems.

[0024] Furthermore, the center rod includes a center ground rod and a vertical telescopic rod from bottom to top. A vertical telescopic groove is provided on the inner side wall of the center ground rod. The vertical telescopic rod is slidably fitted in the vertical telescopic groove. The vertical telescopic rod and the center rod side wall are provided with several telescopic holes along the axial direction. The outer wall of the vertical telescopic rod is fixedly connected with a spring clip corresponding to the position and shape of the several clip holes.

[0025] Beneficial Effect: The spring clip cooperates with the telescopic hole to form a height adjustment locking mechanism. The spring clip can fit tightly with the telescopic hole; when the vertical height of the bracket needs to be adjusted, simply press the spring clip to disengage it from the current telescopic hole, then adjust the bracket to the appropriate height, release the spring clip, and lock it into the corresponding telescopic hole to complete the height locking.

[0026] Furthermore, a driving groove is provided on the top surface of the joint, and a net-discharging cylinder corresponding to the position of the driving groove is fixedly connected to the top surface of the joint, a slide is fixedly connected to the top of the net-discharging cylinder, a motor is fixedly connected in the driving groove, the motor signal is connected with the controller signal, the output end of the motor is fixedly connected to the input pulley, and a number of driving ropes are fixedly connected to the input pulley, one end of the driving rope is clamped on the input pulley, and the other end of the driving rope extends to the surface of the slide and is fixedly connected to a counterweight block, the counterweight blocks are fixedly connected to the edge of the insect-proof net, and the center of the insect-proof net is fixedly connected to the net-discharging cylinder.

[0027] Beneficial Effects: The motor drives the pulley system to control the movement of the counterweight. The motor provides power to the pulley system, which transmits the motor's power to the counterweight. By adjusting the tension of the drive rope, the insect-proof net can be automatically deployed and retracted.

[0028] Furthermore, the slide is a truncated cone-shaped structure in which the inner edge height close to the net-discharging cylinder is higher than the outer edge height away from the net-discharging cylinder.

[0029] Beneficial Effects: The truncated cone-shaped slide optimizes the movement path of the counterweight. This provides a clear path for the counterweight to move. During the net's folding and unfolding, the counterweight moves along the surface of the truncated cone, leveraging gravity to smoothly fold and unfold the net.

[0030] Furthermore, a wire management plate is fixedly connected to the net outlet cylinder, and a plurality of evenly distributed wire management holes are opened on the wire management plate, and the rope bodies of the driving ropes all extend out of the net outlet cylinder through the wire management holes.

[0031] Beneficial effect: The design of the cable management plate and cable management holes forms an orderly wiring channel for the drive ropes. Multiple groups of drive ropes are arranged in an orderly manner on the cable management plate through the cable management holes, avoiding the problem of mutual entanglement and knotting, and ensuring the operational reliability of the automatic retraction and extension system.

[0041] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0044] The following is further described in detail through specific implementation methods:

[0045] Example 1:

[0046] As attached Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The invention discloses a stable support for a single fruit tree covered with an insect-proof net. The support comprises a support 1 and an insect-proof net 2. The support 1 comprises a central rod 3 and several edge rods 4. A joint 5 is welded to the top of the central rod 3. The sidewalls of the joint 5 are evenly provided with a number of covering adjustment rods 6 corresponding to the number of edge rods 4 along its circumference. The covering adjustment rods 6 are each provided with a hanging rod block 7 at the end away from the joint 5. The edge rods 4 are detachably connected to the covering adjustment rods 6 via the hanging rod blocks 7. During use, the fruit farmer inserts the central rod 3 vertically into the ground and close to the trunk of the fruit tree. The hanging rod block 7 is then used to quickly connect the center rods 4 to the edge rods 4. The edge rods 4 are then inserted obliquely or vertically into the soil around the fruit tree, forming a radial support 1 with a stable structure with the central rod 3 as the support point. Finally, the insect-proof net 2 is covered on the surface of the entire support 1, achieving a complete coverage of the tree without blind spots.

[0047] When the fruit trees are shaken by wind or the weight of the fruit, the force exerted on the fruit trees will cause them to come into contact with the local support 1 and the local insect-proof net 2, causing the support 1 or the insect-proof net 2 to be partially subjected to excessive pulling force and friction, resulting in the net being torn or the seams being unhooked. To this end, the covering adjustment rod 6 is designed to include a transverse telescopic rod 601 and a hanging rod tube 602. One end of the transverse telescopic rod 601 is welded to the side wall of the joint 5, and a transverse telescopic groove is provided on the side of the hanging rod tube 602 close to the joint 5. A sliding groove is provided on the side wall of the hanging rod tube 602. The end of the transverse telescopic rod 601 away from the joint 5 is located in the transverse telescopic groove. A slider is integrally formed on the transverse telescopic rod 601 and is slidably connected to the corresponding sliding groove. The transverse telescopic rods 601 are slidably connected to the corresponding transverse telescopic groove through a slider and sliding groove mechanism. When the fruit tree is blown by the wind, the shaking of the fruit tree is reflected as the displacement of branches and leaves. The branches and leaves are in partial contact with the inner side of the bracket 1, which generates a force on the local bracket 1, causing the corresponding transverse telescopic rod 601 to slide in the transverse telescopic groove of the hanging rod tube 602 in the direction of the force, forming a telescopic adjustment of the fruit tree insect-proof cover in the horizontal direction. This movement enables the covering adjustment rod 6 to adapt to the swing amplitude of the fruit tree, release local stress through lateral expansion and contraction, and prevent the insect-proof net 2 from being torn due to hard pulling; at the same time, the limit design of the slide groove maintains the overall stability of the bracket 1, ensuring that the net body still maintains uniform tension under dynamic force, thereby extending the service life of the insect-proof net 2.

[0048] In addition, a return spring 603 is provided at the connection between each transverse telescopic rod 601 and the corresponding hanging rod tube 602, and both ends of the return spring 603 are respectively welded to the corresponding transverse telescopic rod 601 and the hanging rod tube 602. When the fruit tree is shaken by wind or external force, the transverse telescopic rod 601 slides along the transverse telescopic groove of the hanging rod tube 602, and the return spring 603 absorbs the impact energy transmitted by the branch through elastic deformation, thereby buffering the instantaneous pulling force; after the impact, the elastic restoring force of the return spring 603 will drive the transverse telescopic rod 601 to return to its position automatically, that is, drive the insect-proof net 2 as a whole to move following the posture of the branches and leaves of the fruit tree, eliminate the slack or local tension concentration of the insect-proof net 2 caused by dynamic displacement, and at the same time avoid the continuous tension and tearing of the net body caused by the hooking of branches and leaves, maintain the uniform fit between the net body and the bracket 1, and reduce friction loss.

[0049] The special feature is that the connection between the horizontal telescopic rod 601 and the corresponding hanging rod tube 602 is also provided with a magnet ring 604. Figure 3 and Figure 4As shown, one side wall of the magnet ring 604 is welded to the corresponding hanging rod tube 602, and the inner side wall of the magnet ring 604 is fitted with the outer wall of the corresponding horizontal telescopic rod 601, and the outer side wall of the magnet ring 604 is wound with an electromagnetic coil 605, a controller is provided in the joint 5, and a pressure sensor 8 is provided on the edge rod 4. Several pressure sensors 8 and several electromagnetic coils 605 are connected to the controller signal; each pressure sensor 8 is used to respectively collect whether the local inner wall of the bracket 1 is under force, that is, to determine whether the fruit tree is shaking, and the collection of the signal is used as an insect-proof cover The starting factor for the telescopic adjustment of the cover is the intelligent control of the opening and closing of the electromagnetic coil 605. When the electromagnetic coil 605 is powered off, the magnetic attraction of the magnet ring 604 is used to achieve self-locking limit of the slide (that is, the magnetic attraction of the magnet ring 604 is used to fix the corresponding transverse telescopic rod 601 and the hanging rod tube 602), without the need for additional mechanical clips for limiting; when the electromagnetic coil 605 is powered on, the electromagnetic field generated by the electromagnetic coil 605 offsets the magnetic attraction of the magnet ring 604, and releases the sliding limit of the transverse telescopic rod 601 and the hanging rod tube 602 to adjust the coverage range.

[0050] Based on the limit and unlocking of the insect-proof coverage range adjustment, a humidity sensor 9 is designed to be fixedly connected to the central pole 3 by bolts, and the humidity sensor 9 is connected to the controller signal. Since the airtight insect-proof coverage of the entire tree may hinder natural ventilation and light transmission, resulting in increased local humidity in the fruit trees, increasing the probability of fungal diseases (such as powdery mildew), the humidity sensor 9 is used to monitor the humidity data of the fruit tree canopy in the insect-proof net 2 in real time. When the humidity exceeds the standard, the controller sends current to the electromagnetic coil 605 to offset the permanent magnetic attraction. By adjusting the power of the electromagnetic coil 605 to adjust the degree of offset of the permanent magnet attraction, the telescopic adjustment of the horizontal telescopic rod 601 is achieved to adjust the increase in the space inside the net; and after detecting that the humidity has recovered, the power supply is stopped, and the permanent magnet and the ferromagnetic material are re-adsorbed and locked to maintain the stability of the coverage range.

[0051] Experiment 1:

[0052] Experimental purpose: To evaluate the effect of the bracket's adaptive stress release function on reducing the probability of insect screen breakage;

[0053] Experimental steps:

[0054] 1. Experimental grouping and settings:

[0055] Experimental group: 20 fruit trees of the same variety (e.g., citrus) were selected and installed with insect-proof nets using the structure designed in this scheme;

[0056] Control group: 20 fruit trees of the same variety were selected and installed with traditional fixed insect-proof net supports (without adaptive adjustment function).

[0057] Environmental conditions: The two groups of fruit trees were planted in adjacent areas with the same soil, light and water conditions. The experimental period was 6 months (covering the fruit ripening period).

[0058] 2. Insect prevention effect test:

[0059] Pest monitoring: The number of major pests (e.g., fruit flies and aphids) in the canopy of two groups of fruit trees was counted weekly, recorded using traps or visual inspection.

[0060] Fruit damage rate: At the end of the experiment, the percentage of insect-damaged areas on the fruit surfaces of the two groups was counted.

[0061] 3. Test on probability of insect net breaking:

[0062] Simulate wind disturbance: Use a wind turbine to apply simulated wind force (wind speed 8-12 m / s, continuous 30 minutes / day, for 10 days) to the two sets of brackets, and record the number of times the insect screen is damaged.

[0063] Dynamic stress test: A robotic arm is used to simulate the shaking of the fruit tree (amplitude ±15cm, frequency 0.5Hz, duration 5 minutes / time, total 50 times) to observe whether the seams of the insect-proof net are unhooked or torn.

[0064] Experimental data:

[0065] Table 1: Comparison of insect repellent effect data

[0066]

[0067]

[0068] Table 2: Comparison of damage effect of insect screen

[0069] Test conditions Experimental group (this design) Control group (traditional stent) Number of wind disturbance damages 1 time (local relaxation) 9 times (torn or unhooked) Dynamic stress failure rate 0％ 42％

[0070] Experimental conclusion:

[0071] The number of pests in the experimental group decreased by 66.7% (5 vs. 15), and the fruit damage rate decreased by 83.3% (3% vs. 18%), indicating that the airtightness and adaptive adjustment function of the bracket design proposed in this scheme effectively blocked the invasion path of pests.

[0072] The experimental group experienced only one slight relaxation (no tearing) under wind disturbance, while the control group experienced nine breakages due to fixed pulling. In the dynamic stress test, the experimental group experienced no breakage, while the control group experienced a breakage rate of 42%. Data demonstrates that the new bracket, through the linkage control of elastic reset components and pressure sensors, controls the maximum force of the insect-proof net within the material safety range (<80N), avoiding the risk of tearing caused by stress concentration.

[0073] Example 2:

[0074] As attached Figure 5 As shown, the difference from Example 1 is that the center rod 3 includes a center ground rod 301 and a vertical telescopic rod 302 from bottom to top. The inner wall of the center ground rod 301 is provided with a vertical telescopic groove, and the vertical telescopic rod 302 slides into the vertical telescopic groove. The side wall of the center rod 3 is provided with a plurality of telescopic holes 303 along the axial direction, and the outer wall of the vertical telescopic rod 302 is embedded with a spring clip 304 corresponding to the position and shape of the plurality of telescopic holes 303. During the installation of the bracket 1, the fruit farmer can press the spring clip 304 to disengage it from the current telescopic hole 303, manually push and pull the vertical telescopic rod 302 to the target height (such as citrus trees need to be adjusted to 2.5 meters, and bayberry trees need to be adjusted to 1.8 meters), and release the spring clip 304 to automatically embed it into the telescopic hole 303 of the corresponding height to complete the locking. This structure can adapt to the height requirements of different fruit trees without tools, and the clip has strong wind resistance and stability after being embedded, ensuring that the insect-proof net 2 always maintains a safe vertical distance from the tree crown to avoid friction and damage to branches and leaves.

[0075] Example 3:

[0076] As attached Figure 2 and Figure 3 As shown, the difference from Example 2 is that the edge rods 4 include arc rods 401 and edge ground rods 402 from top to bottom, the tops of the edge ground rods 402 are hinged to the arc rods 401, the tops of the arc rods 401 are welded with through hanging rods 4011, and the hanging rod blocks 7 are provided with 'U'-shaped hanging rod grooves 701, the through hanging rods 4011 vertically penetrate the tops of the arc rods 401, and the shapes of the through hanging rods 4011 correspond to the shapes of the hanging rod grooves 701. When installing the bracket 1, the fruit farmers put the bottoms of the edge ground rods 402 After the end is inserted into the ground and fixed, the through-hanging rod 4011 at the top of the arc rod 401 is quickly engaged with the "U"-shaped groove on the hanging rod block 7, and self-locking is achieved by geometric adaptation of the hanging rod groove 701 and the through-hanging rod 4011, without the need for additional fastening tools; the hinged design allows the arc rod 401 to be fine-tuned at an angle during installation to adapt to the overall displacement of the bracket 1 when the insect-proof coverage range is telescopically adjusted. This design allows the entire installation process to only require two steps of inserting into the ground and hooking to complete the construction of the bracket 1 for a single fruit tree, greatly improving work efficiency and reducing labor costs.

[0077] Example 4:

[0078] As attached Figure 6 and Figure 7As shown, the difference from Example 3 is that a driving groove 10 is opened on the top surface of the joint 5, and a net-outlet cylinder 11 corresponding to the position of the driving groove 10 is welded on the top surface of the joint 5, and a slide 12 is welded on the top of the net-outlet cylinder 11. The slide 12 is a truncated cone-shaped slide 12 with an inner edge height close to the net-outlet cylinder 11 higher than the outer edge height away from the net-outlet cylinder 11. A motor 13 is fixedly connected to the driving groove 10 by screws, and the motor 13 is connected to the controller signal. The output end of the motor 13 is fixedly connected to the input pulley 14 through a coupling, and a number of driving ropes 15 are wound around the input pulley 14. A wire management plate 16 is integrally formed in the net-outlet cylinder 11, and the wire management plate 1 6 is provided with a number of evenly distributed wire management holes 17, the design of which can guide the trajectory of the drive rope 15 and prevent the drive ropes 15 from getting tangled with each other; one end of the drive rope 15 is clamped on the input pulley 14, and the other end of the drive rope 15 extends through the corresponding wire management hole 17. The surface of the slide 12 is fixedly connected to a counterweight 18, which is adhered to the edge of the insect-proof net 2 and fixed to the center of the wire management plate 16. With this design, fruit farmers can start the motor 13 through the controller to drive the input pulley 14 to rotate and synchronously reel or release the drive rope 15, thereby driving each counterweight 18 to rise and fall along the surface of the slide 12. When covering, the motor 13 rotates forward, the drive rope 15 pulls down the counterweight 18, and the insect-proof net 2 is evenly stretched and fits the fruit tree; when retracting, the motor 13 reverses, the drive rope 15 relaxes, and the counterweight 18 slides to the lower position of the slide 12 due to gravity, and the insect-proof net 2 automatically folds and is stored in the net cylinder 11.

[0079] The inclined design of the slide 12 can guide the counterweight 18 back to its original position without manual intervention throughout the process, achieving efficient covering / retracting operations, improving efficiency and reducing labor intensity.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
