Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco seedling transplanting, and in particular relates to a flexible clamping device for tobacco seedling transplanting. Background Art

[0002] Tobacco seedling transplanting refers to the process of transferring grown tobacco seedlings from a nursery bed or nursery trough to a tobacco field or planting site using a clamping device. This process is a crucial step in tobacco cultivation and is usually carried out after the seedlings have grown to an appropriate height and growth stage. Selecting strong, pest-free tobacco seedlings during transplanting can effectively increase tobacco survival rates and promote later growth. Proper transplanting timing and techniques can increase tobacco yields by ensuring adequate water and nutrients at each growth stage. Transplanting allows the seedlings' roots to better adapt to the new soil environment, promoting further root development and increasing their ability to absorb water and nutrients. Environmental conditions (such as light and temperature) may differ between the seedlings growing in the nursery bed and those in the planting site. Transplanting allows the seedlings to better adapt to local climate and soil conditions. Pre-transplant prevention and control measures can be implemented during the seedling stage to reduce the impact of pests and diseases on tobacco growth, thereby improving the quality and market competitiveness of the tobacco leaves.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a flexible clamping device for transplanting tobacco seedlings, which includes a handle support, a rotating member, a fixing member and a clamping member. The handle support is a cylindrical structure. The rotating member is arranged inside the handle support, and its end extends to the handle support. The fixing member is arranged between the handle support and the rotating member, and the fixing member is used to limit the rotation angle of the rotating member. The front end of the handle support is provided with the clamping member, and one side of the clamping member is fixedly connected to the rotating member, and is used to clamp the tobacco seedlings after adjusting the opening and closing angle.

[0007] A silica gel layer is provided at the position where the interior of the clamping member contacts the tobacco seedling, for protecting the clamped tobacco seedling.

[0008] On the basis of the above technical solution, the flexible clamping device for transplanting tobacco seedlings of the present invention can also be improved as follows:

[0009] Wherein, a circular ring structure is provided at the end of the handle support, and the circular ring structure is arranged at the center and the center of the edge of the end cross section of the handle support.

[0010] Furthermore, the end cross-section of the handle support is divided into two parts, an edge ring and an inner disc, by the circular ring structure, and the inner disc is fixedly connected to the edge ring by a fixing rod.

[0011] Furthermore, the rotating member includes a rotating cylinder, a compression spring and a rotating rod. The outer diameter of the rotating cylinder is smaller than the inner diameter of the handle support. The compression spring is arranged between the center position of the rotating cylinder and the center position of the handle support. The two ends of the compression spring are respectively fixedly connected to the end of the rotating cylinder and the center position of the inner disk of the handle support; the rotating rod is fixed to the side of the rotating cylinder close to the inner disk, and the rotating rod corresponds to the position of the circular structure.

[0012] Furthermore, the length of the rotating rod is greater than 1.5 times the distance between the end of the rotating cylinder and the end of the handle support when the compression spring is not under force.

[0013] Furthermore, the front end of the rotating cylinder is a double-step rotating disk structure, and an arc groove is provided on the side thereof, and the position of the arc groove corresponds to the position of the side wall of the handle support.

[0014] Furthermore, the diameter of the double-step rotating disk structure is larger than the cross-sectional diameter of the handle support.

[0015] Furthermore, the fixing member includes a fixing rod and a fixing slot, the fixing rod is fixed on the side wall of the rotating cylinder, the fixing slot is arranged on the side wall of the handle support, and the fixing rod and the fixing slot are arranged in a corresponding position.

[0016] Furthermore, the fixing groove is a multi-L-shaped structure, one side of which is aligned and through-set, and the length of the other side increases sequentially.

[0017] Furthermore, the clamping member includes a fixed edge and a rotating edge, the fixed edge passes through the arc groove and is fixedly connected to the side wall of the handle support member, and the rotating edge is fixedly connected to the front end side of the rotating cylinder; an arc-shaped edge is provided at the bottom position of the fixed edge and the rotating edge for supporting the clamping of the tobacco seedlings.

[0018] Compared with the prior art, the flexible clamping device for transplanting tobacco seedlings provided by the present invention has the following beneficial effects:

[0019] The handle support is quasi-cylindrical, providing a comfortable grip and facilitating the operator's application of force. A ring structure at the end of the handle support enhances stability and helps the operator better control the device. The split design of the handle support, consisting of an edge ring and an inner disc, allows the handle support to better withstand external forces and improves its torsional resistance. This provides stable support, ensuring the entire clamping device maintains excellent stability when holding the tobacco seedlings.

[0020] The rotating rod is housed within the handle support, making it highly discreet and easy to grasp. A compression spring provides additional restoring force, helping the rotating rod return to its original position. The double-step rotating disc design provides a wider clamping range and facilitates adjustment of the clamping angle. The limited rotation angle ensures more precise clamping and prevents over-tightening or over-loosening.

[0021] Ensure the smoothness of the clamping action, improve the clamping efficiency and reduce damage to the tobacco seedlings.

[0022] The fixing element is connected to the fixing slot of the handle support via a fixing rod, effectively limiting the rotation angle of the rotating element. The multiple L-shaped fixing slots allow for flexible adjustment of the fixing position of the rotating element to accommodate tobacco seedlings of varying sizes. This ensures consistent clamping action and prevents clamping failure due to unstable rotation angles. The adjustable fixing slots enhance the adaptability of the device, making it suitable for tobacco seedlings of varying diameters.

[0023] The separate design of the fixed edge and the rotating edge allows the clamp to form a reasonable opening and closing angle when clamping, reducing the pressure on the tobacco seedlings.

[0024] A silicone layer is placed inside the clamp where it contacts the tobacco seedling, protecting it from damage. This layer provides a soft feel and effectively absorbs pressure during clamping, protecting the seedling from damage. The optimized clamping angle allows for greater flexibility, adapting to varying tobacco seedling shapes and sizes. BRIEF DESCRIPTION OF THE DRAWINGS
