Description

Technical Field

[0001] This utility model relates to the field of support rod device technology, and in particular to an adjustable support rod device for flue-cured tobacco baskets. Background Technology

[0002] Aphids are a major vector for disease transmission during tobacco cultivation, especially since they are attracted to the color blue. They become a key focus of pest and disease control in tobacco fields between May and June each year. Farmers typically set up blue sticky traps in tobacco fields to catch tobacco aphids and other harmful insects.

[0003] However, existing blue plate support rods are not adjustable in length, making it difficult to adapt to changes in tobacco plant growth, resulting in less than ideal control effects. Therefore, there is an urgent need to develop a blue plate support rod device that can be flexibly adjusted according to the growth of tobacco plants. Utility Model Content

[0004] The main purpose of this utility model is to provide an adjustable flue-cured tobacco blue plate support device to solve the problem that the existing blue plate support is difficult to adapt to changes in tobacco plant growth because its length is not adjustable.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A support rod, in which a lifting rod is slidably installed, and a limiting mechanism is installed inside the lifting rod to fix the position of the lifting rod;

[0008] Two blue plates are installed on the lifting rod. The blue plates have serrated notches, and a transparent film is installed on the notches. The film is coated with adhesive. An adsorption and fixing mechanism is installed inside the blue plate to adsorb and fix the film.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0026] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1 and Figure 3-4As shown, this embodiment provides an example of an adjustable flue-cured tobacco basket support device. In this embodiment, the support device includes a support rod 1, and a tapered rod 102 is fixedly installed at the bottom of the support rod 1. The bottom of the tapered rod 102 has a tapered structure, which facilitates the insertion of the support rod 1 into the ground to fix the entire support device. A lifting rod 101 is slidably installed inside the support rod 1. By sliding the lifting rod 101, the lifting rod 101 can be moved along the axial direction of the support rod 1, thereby adjusting the total length of the support rod 1 and the lifting rod 101. A limiting mechanism is installed inside the lifting rod 101 to fix the position of the lifting rod 101. The limiting mechanism can fix the position of the lifting rod 101 after the height adjustment is completed.

[0029] Furthermore, the limiting mechanism includes a drive shaft 103 rotatably mounted inside the lifting rod 101 and two friction plates 104 slidably mounted on the lifting rod 101. The friction plates 104 can provide a large frictional force. When the friction plates 104 are pressed against the inner wall of the support rod 1, the frictional force between the inner wall of the support rod 1 and the friction plates 104 is sufficient to fix the lifting rod 101. A drive rod 105 is rotatably mounted on the friction plates 104, and the other end of the drive rod 105 is rotatably connected to the drive shaft 103. By rotating the drive shaft 103, the drive rod 105 can be driven to rotate. The rotating drive rod 105 can pull or push the friction plates 104 to move, allowing the friction plates 104 to move closer to or away from the inner wall of the support rod 1. A handle 106 is fixedly mounted on one end of the drive shaft 103, and a torsion spring 107 is fixedly mounted on the handle 106. The other end of the torsion spring 107 is fixedly connected to the lifting rod 101. By rotating the lever 106, the drive shaft 103 can be driven to rotate. Under the elastic force of the torsion spring 107, when the drive shaft 103 is not subjected to external force, the friction plate 104 will always abut against the inner wall of the support rod 1, thereby effectively ensuring the stability between the friction plate 104 and the support rod 1, and thus keeping the support rod 1 and the lifting rod 101 stable.

[0030] like Figure 1-2 and Figure 5-6 As shown, this embodiment also includes two blue plates 3 installed on the lifting rod 101. The surface of the blue plates 3 is coated with blue pigment. By setting serrated notches 301 on the surface of the blue plates 3 and covering the notches 301 with a transparent film 302, and coating the film 302 with adhesive, the surface of the blue plates 3 can support a larger area of ​​film 302. The adhesive can also be used to adhere harmful insects, thereby effectively killing pests. An adsorption and fixing mechanism is installed inside the blue plates 3 to adsorb and fix the film 302. The adsorption and fixing mechanism facilitates the fixing of the film 302 to the blue plates 3 and makes disassembly easy.

[0031] Among them, a support base 2 is fixedly installed on the lifting rod 101, and the blue plate 3 is fixedly connected to the support base 2. By setting the notches 301 on the two blue plates 3 opposite to each other, the blue plates 3 can effectively stick pests to both sides.

[0032] Furthermore, the adsorption and fixing mechanism includes multiple adsorption holes 4 on the notch 301, an adsorption cavity 401 located in the blue plate 3 and communicating with the notch 301, an air extraction box 402 fixedly installed on the blue plate 3, the air extraction box 402 communicating with the adsorption cavity 401, a sealing plate 403 slidably installed in the air extraction box 402, and a sealing strip 404 fixedly installed on the sealing plate 403. The sealing strip 404 can seal the gap between the sealing plate 403 and the suction box 402, ensuring good airtightness between them. When the film 302 is attached to the blue plate 3, the adsorption holes 4 will be blocked by the film 302. At this time, pulling the sealing plate 403 upward will reduce the air pressure inside the adsorption chamber 401. Since the air pressure inside the adsorption chamber 401 is lower than the external air pressure, the film 302 can be adsorbed and fixed on the blue plate 3 under the action of the internal and external pressure difference, thus completing the installation of the film 302. Furthermore, since the adsorption holes 4 are evenly distributed on the entire blue plate 3, the stability of the adsorption of the film 302 can be effectively guaranteed, and the adhesion between the film 302 and the blue plate 3 can be ensured.

[0033] Furthermore, the adsorption and fixing mechanism also includes a connecting column 405 fixedly installed on the sealing plate 403. The connecting column 405 is slidably connected to the suction box 402. A connecting rod 406 is rotatably installed on the connecting column 405, and a pressure rod 407 is rotatably installed on the connecting rod 406. The pressure rod 407 is rotatably connected to the suction box 402. The rotatable connection between the pressure rod 407 and the suction box 402 is close to the connecting rod 406. When one end of the pressure rod 407 is pressed, the connecting rod 406 can be driven to move up and down, which can effectively save effort. The rising and falling connecting rod 406 can drive the sealing plate 403 to move up and down.

[0034] It is worth noting that a counterweight ball 408 is fixedly installed at one end of the pressure rod 407. The counterweight ball 408 can effectively apply resistance when the sealing plate 403 is lowered, which can ensure the stability of the air pressure inside the adsorption chamber 401. The top of the air extraction box 402 is provided with an air hole, through which the gas above the sealing plate 403 can be discharged. When installing the film 302, the pressure plate 5 can be used. One side of the pressure plate 5 is provided with a serrated groove 501. By combining the pressure plate 5 with the blue plate 3, the film 302 can be attached to the blue plate 3, and then the film 302 can be fixed by the adsorption fixing mechanism.

[0035] This invention allows the drive shaft 103 to rotate, which in turn drives the drive rod 105 to rotate. The rotating drive rod 105 can pull or push the friction plate 104 to move, allowing the friction plate 104 to move closer to or further away from the inner wall of the support rod 1. Under the elastic force of the torsion spring 107, when the drive shaft 103 is not subjected to external force, the friction plate 104 will always be against the inner wall of the support rod 1, thereby effectively ensuring the stability between the friction plate 104 and the support rod 1, and thus keeping the support rod 1 and the lifting rod 101 stable.

[0036] By combining the pressure plate 5 with the blue plate 3, the film 302 can be adhered to the blue plate 3. Pressing one end of the pressure rod 407 can drive the connecting rod 406 to move up and down, which can effectively save effort. The lifting connecting rod 406 can drive the sealing plate 403 to move up and down. Pulling the sealing plate 403 upward can reduce the air pressure inside the adsorption chamber 401. At this time, the air pressure inside the adsorption chamber 401 is lower than the external air pressure. Under the action of the internal and external pressure difference, the film 302 can be adsorbed and fixed on the blue plate 3, thus completing the installation of the film 302. Since the adsorption holes 4 are evenly arranged on the entire blue plate 3, the stability of the adsorption of the film 302 can be effectively guaranteed, and the adhesion between the film 302 and the blue plate 3 can be guaranteed.

[0037] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
