[0002] Tea is a valuable economic crop, and its green pest control is particularly important, with pest control being a crucial part of green pest control.

[0003] In existing technologies, pest and disease control typically involves using insect-attracting lamps to lure pests and then killing them with electric grids, or using pesticides to lure pests and then using sticky traps. The control devices are installed using support structures. However, tea trees vary in height, and the support structures are usually not easy to adjust in height and are not uniform in size. If the distance between the insect-attracting lamps or pesticides and the tea trees does not meet the attraction requirements, the attraction effect will be poor, resulting in poor control. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a pest and disease control device for tea, so as to solve the problem that the distance between the insect-attracting lamp and the tea tree in the existing tea control device is not easy to adjust, which leads to a reduction in the attraction effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pest and disease control device for tea plants, comprising: A support member, the top of which is provided with a mounting base, and a rainproof member that can extend and retract radially is telescopically connected to the mounting base; An insect-attracting and control component is mounted on the supporting member via a parallel four-bar linkage. This component is moved by the linkage to adjust its height. The parallel four-bar linkage is connected to the rain-shielding member via a connecting rod assembly, allowing the rain-shielding member to extend and retract radially through its movement. A drive component that drives the parallel four-bar linkage mechanism. The linkage assembly includes linkage one, linkage two, and linkage three. Linkage one is connected to a parallel four-bar linkage mechanism. Linkage one, linkage two, and linkage three are hinged together at a connection point to form a Y-shaped linkage movable structure. Linkage two is hinged to the rainproof component, and linkage three is hinged to the support component.

[0006] In a possible implementation, link two is longer than link three.

[0007] In a possible implementation, the parallel four-bar linkage includes a first connecting arm and a second connecting arm, both of which are hinged to a support member. The insect-attracting and control component is hinged between the first and second connecting arms. The first connecting arm is hinged to a first connecting rod, and the second connecting arm is connected to a drive component.

[0008] In a possible implementation, the drive assembly includes an adjusting rod and an adjusting seat. The adjusting seat is mounted on a support member and has a plurality of positioning slots along the longitudinal direction. The adjusting rod is hinged to a four-bar linkage and has a stop portion that engages with the positioning slots.

[0009] In one possible implementation, the abutment has a T-shaped structure, such that the two ends of the abutment form a retaining shaft, and the adjusting seat has two sets of positioning slots arranged side by side, with the retaining shafts at both ends of the abutment respectively embedded in the two sets of positioning slots.

[0010] In a possible implementation, the parallel four-bar linkage is connected to the support member via a sliding sleeve, the sliding sleeve being fitted onto the outside of the support member, and an elastic support member fitted onto the support member is fixed below the sliding sleeve, the elastic support member supporting the movable sleeve, and a locking component is provided between the sliding sleeve and the support member.

[0011] In a possible implementation, the insect-attracting and control component includes a lampshade, a lamp holder, an insect-attracting lamp, and a ring-shaped electric grid. The lampshade is connected to the lamp holder via a protective rod, the insect-attracting lamp is located between the lampshade and the lamp holder, and the ring-shaped electric grid is spaced outside the insect-attracting lamp.

[0012] In one possible implementation, a ring-shaped cleaning brush is provided on the outside of the ring-shaped grid, the cleaning brush frictionally engaging with the ring-shaped grid, and the cleaning brush having an operating handle extending out of the lampshade.

[0013] In a possible implementation, the lamp holder includes a central connecting block and a connecting ring. The diameter of the central connecting block is equal to or smaller than the outer diameter of the ring-shaped electrical grid. The connecting ring is connected to an outer connecting ring via several circumferentially distributed support rods. Several insect discharge ports are formed between the connecting ring and the central connecting block via the support rods.

[0014] In one possible implementation, the insect-attracting and control components are provided in two sets and are respectively mounted on the support member via a set of parallel four-bar linkages.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a pest and disease control device for tea plants. Through a parallel four-bar linkage mechanism, the height of the pest control component or its distance from the tea leaves can be adjusted with the help of the drive component. It also allows the pest control component to have both retracted and extended states, making it easier to use. Furthermore, the device adopts a linkage design, which can drive the rain-shielding component to extend or retract synchronously when adjusting the pest control component.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0021] Please refer to Figure 1-7 As shown, an embodiment of this application provides a pest and disease control device for tea, comprising: a support member 3, a mounting base 6 on the top of the support member 3, and a rain-shielding member 7 that is retractable in the radial direction connected to the mounting base 6; an pest and disease control component 4 disposed on the support member 3 via a parallel four-bar linkage 5, the pest and disease control component 4 being driven by the parallel four-bar linkage 5 to adjust its height, the parallel four-bar linkage 5 being connected to the rain-shielding member 7 via a link assembly 8, so that the rain-shielding member 7 can be retracted in the radial direction by the movement of the parallel four-bar linkage 5; and a drive assembly 9 for driving the movement of the parallel four-bar linkage 5.

[0022] The support member 3 provides overall support for the device. It employs a rod-like structure, with a mounting base 6 at its top for the installation of the rain-shielding member 7. The rain-shielding member 7 is mounted on the mounting base 6 using a telescopic structure, allowing it to extend and retract radially to adjust the rain-shielding range. This works in conjunction with the insect-attracting and control component 4 to provide shelter at different heights. The telescopic nature of the rain-shielding member 7, working in conjunction with the insect-attracting and control component 4, reduces sunlight obstruction to surrounding tea trees at lower heights, thus minimizing the impact on tea tree growth. The insect-attracting and control component 4 is used to attract and kill pests. It is mounted on the support member 3 via a parallel four-bar linkage 5. This linkage 5 allows for easy adjustment of its height and distance from the tea trees. Furthermore, the parallel four-bar linkage 5 enables the insect-attracting and control component 4 to move horizontally without tilting during adjustment, ensuring more stable and reliable adjustment. The rain-shielding component 7 is driven to extend and retract via a linkage mechanism. Specifically, it is connected to the parallel four-bar linkage 5 through the linkage assembly 8. The movement of the parallel four-bar linkage 5 converts the force, primarily acting in the vertical direction, into a radial force that drives the rain-shielding component 7, thus achieving the extension and retraction transmission of the rain-shielding component 7. The parallel four-bar linkage 5 is equipped with a drive assembly 9 that drives its movement. The drive assembly 9 can be electrically driven or manually driven, without limitation.

[0023] In order to enable the parallel four-bar linkage 5 to effectively transmit power to the rain-shielding component 7, in the embodiments of this application, the linkage assembly 8 includes a first linkage 81, a second linkage 82, and a third linkage 83. The first linkage 81 is connected to the parallel four-bar linkage 5. The first linkage 81, the second linkage 82, and the third linkage 83 are hinged together at a connection point to form a Y-shaped linkage movable structure. The second linkage 82 is hinged to the rain-shielding component 7, and the third linkage 83 is hinged to the support component 3.

[0024] Link 1 81, link 2 82 and link 3 83 are connected to form a Y-shaped linkage movable structure. This structure can decompose the main longitudinal force of the parallel four-bar linkage structure during height adjustment into a force component that can drive the extension and retraction of the rain shelter component 7, thereby facilitating the extension and retraction drive of the rain shelter component 7.

[0025] Through the above technical solution, the parallel four-bar linkage 5 can adjust the height of the insect-attracting and control component 4 or its distance from the tea leaves with the cooperation of the drive component 9. It also allows the insect-attracting and control component 4 to have a retracted and extended state, making it easier to use. Furthermore, the device adopts a linkage design, which can drive the rain-shielding component 7 to extend or retract synchronously when adjusting the insect-attracting and control component 4. This allows for matching different shielding ranges of the insect-attracting and control component 4 at different heights, making operation simpler, improving practicality, and enabling better pest and disease control.

[0026] In one embodiment, the second link 82 is longer than the third link 83.

[0027] By configuring the length of connecting rod 2 82 to be longer than that of connecting rod 3 83, the angle between connecting rod 2 82 and the rain shelter component 7 when driven by connecting rod 1 81 can be controlled within a relatively small range, so as to avoid the problem that the rain shelter component 7 cannot be effectively driven due to the excessive angle.

[0028] In a preferred embodiment of the parallel four-bar linkage 5, the parallel four-bar linkage 5 includes a first connecting arm 51 and a second connecting arm 52, both of which are hinged to the support member 3. The insect-attracting and control component 4 is hinged between the first connecting arm 51 and the second connecting arm 52. The first connecting arm 51 is hinged to the first connecting rod 81, and the second connecting arm 52 is connected to the drive component 9.

[0029] Connecting arms 51 and 52, in conjunction with the support member 3, enable the insect-attracting and control component 4 to be installed via the parallel four-bar linkage 5. The insect-attracting and control component 4 maintains a parallel position to the support member 3 throughout the movement of the parallel four-bar linkage 5, thus ensuring greater stability during and after adjustment. Furthermore, the insect-attracting and control component 4 can also move radially during the movement driven by the parallel four-bar linkage 5, allowing for adjustment of its lateral position beyond height.

[0030] In a preferred embodiment of the drive assembly 9, the drive assembly 9 includes an adjusting rod 93 and an adjusting seat 91. The adjusting seat 91 is disposed on the support member 3 and has a plurality of positioning slots 92 along the longitudinal direction. The adjusting rod 93 is hinged to a four-bar linkage and has abutting parts that cooperate with the positioning slots 92.

[0031] In this implementation structure, the adjusting seat 91 is provided with multiple positioning slots 92 distributed longitudinally. The positioning slots 92 on the adjusting rod 93 can be engaged by the abutment part of the adjusting rod 93. When the abutment part is engaged in the positioning slots 92 at different heights, it will drive the connecting arm 52 of the parallel four-bar linkage 5 to rotate upward around the hinge point. That is, through the lifting action, the parallel four-bar linkage can be driven to move upward, thereby adjusting different heights.

[0032] Furthermore, in order to make the snap-fit ​​more stable and reliable, in the embodiments of this application, the abutment part has a T-shaped structure, so that the two ends of the abutment part form a snap-fit ​​shaft 94, and the adjustment seat 91 is provided with two sets of positioning slots 92 side by side, and the snap-fit ​​shafts 94 at both ends of the abutment part are respectively snapped into the two sets of positioning slots 92.

[0033] In this way, the T-shaped abutment part can abut more stably and effectively in the positioning slot 92, and a groove is formed between the two sets of positioning slots 92, which can limit the arm of the adjusting rod 93 in the lateral direction, further improving the stability of the support.

[0034] To further improve the height adjustment range and make adjustment more effortless, the parallel four-bar linkage 5 is connected to the support member 3 via a sliding sleeve 31. The sliding sleeve 31 is fitted onto the outside of the support member 3, and an elastic support member 32, fitted onto the support member 3, is fixed below the sliding sleeve 31. The elastic support member 32 supports the movable sleeve, and a locking component 33 is provided between the sliding sleeve 31 and the support member 3. The sliding height range can be selected and configured according to actual needs.

[0035] Both the parallel four-bar linkage 5 and the insect-attracting and control component 4 are mounted on the sliding sleeve 31, which is slidably fitted onto the support member 3. Thus, the height of the insect-attracting and control component 4 can be further adjusted by axial movement of the sliding sleeve 31. Since an elastic support member 32 is provided below the sliding sleeve 31, preferably a spring, the spring force can partially offset the weight of the sliding sleeve 31 and the parallel four-bar linkage 5 and the insect-attracting and control component 4 on it. This facilitates height adjustment by moving the sliding sleeve 31, and after height adjustment, it can be locked and fixed by the locking member 33.

[0036] Specifically, locking component 33 uses a locking bolt.

[0037] In an embodiment of this application, the insect-attracting and control component 4 includes a lampshade 41, a lamp holder, an insect-attracting lamp 44, and a ring-shaped electric grid 43. The lampshade 41 is connected to the lamp holder through a protective rod 42. The insect-attracting lamp 44 is disposed between the lampshade 41 and the lamp holder. The ring-shaped electric grid is spaced outside the insect-attracting lamp 44.

[0038] The insect-attracting lamp 44 of the insect-attracting component is positioned between the lamp cover 41 and the lamp holder. A ring-shaped electric grid 43 is positioned outside the insect-attracting lamp 44, and protective rods 42 are distributed circumferentially around the ring-shaped electric grid 43. These protective rods 42 provide protection, preventing accidental hand insertion and ensuring greater safety. When the insect-attracting lamp 44 lures insects to the ring-shaped electric grid 43, the grid electrocutes and kills the insects, thus achieving insect control and reducing the impact of pests and diseases on tea.

[0039] Furthermore, in order to clean the ring-shaped electric grid 43, a ring-shaped cleaning brush 49 is provided on the outer side of the ring-shaped electric grid 43. The cleaning brush 49 is frictionally engaged with the ring-shaped electric grid 43, and the cleaning brush 49 is provided with an operating handle 410 extending out of the lamp cover 41.

[0040] In this way, maintenance personnel can use the operating handle 410 to move the cleaning brush 49 up and down to clean the dead insects and residues adhering to the ring-shaped electric grid 43, thus keeping the ring-shaped electric grid 43 in a usable state and ensuring the extermination effect.

[0041] Considering that the dead insects killed by the ring grid 43 will accumulate on the lamp holder, in order to solve this technical problem, the lamp holder includes a central connecting block 45 and a connecting ring 46. The diameter of the central connecting block 45 is equal to or smaller than the outer diameter of the ring grid 43. The connecting ring is connected to the outer connecting ring 46 by a number of circumferentially distributed support rods 47. A number of insect discharge ports 48 are formed between the connecting ring 46 and the central connecting block 45 by the support rods 47.

[0042] In this way, by constructing multiple insect discharge ports 48 on the lamp holder through the connecting ring 46 and the central connecting block 45, the insect discharge ports 48 can allow the diseased insects that have been killed to fall to the ground, instead of accumulating on the lamp holder, thus solving the problem of accumulation.

[0043] In practical implementation, the insect-attracting and control components 4 are provided in two sets, each connected to the support member 3 via a parallel four-bar linkage 5. Correspondingly, a set of rain-shielding components 7, linkage components 8, and drive components 9 are also provided, forming a symmetrical arrangement. Each set of insect-attracting and control components 4 is covered and shielded by a rain-shielding component 7, thus providing rain protection while reducing the shielded area and avoiding excessive shading of the tea trees' sunlight. Furthermore, the symmetrical arrangement facilitates adjustment of the insect-attracting and control components on both sides, making it more convenient and flexible.

[0044] In addition, a base is provided at the bottom of the support member 3, which can be an anchored base 1 or a counterweight support base 2.

[0045] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
