Description

Technical Field

[0001] This utility model relates to the field of bud-suppressing devices, and more specifically, to a topping and bud-suppressing device for tobacco cultivation. Background Technology

[0002] In tobacco cultivation, topping and bud suppression are key agronomic measures. Topping removes apical dominance from the tobacco plant, promoting nutrient transfer to the leaves and improving leaf yield and quality; bud suppression effectively inhibits the growth of axillary buds, preventing them from competing with leaves for nutrients and ensuring normal leaf development. Traditional topping and bud suppression methods rely heavily on manual operation, which is not only labor-intensive and inefficient, but also difficult to guarantee consistent manual operation, potentially affecting the overall growth and quality of the tobacco. With the development of agricultural mechanization, various topping and bud suppression devices have emerged. These devices have improved operational efficiency to a certain extent, reduced labor intensity, and provided strong support for large-scale and standardized tobacco production.

[0003] During the operation of the device, it is necessary to ensure that the drug can act evenly on the axillary buds of the tobacco plants. The drug is difficult to mix thoroughly and evenly, resulting in an uneven distribution of drug concentration within the device. Uneven drug concentrations sprayed onto the tobacco plants will cause inconsistent bud suppression effects; some plants will not show good axillary bud suppression, while others may suffer phytotoxicity due to excessively high drug concentrations, affecting the normal growth and final quality of the tobacco.

[0004] Therefore, we have made improvements to this and proposed a topping and bud-suppressing device for tobacco cultivation. Utility Model Content

[0005] In order to achieve the above-mentioned objectives, this utility model provides a topping and bud-suppressing device for tobacco cultivation to improve the aforementioned problems.

[0006] The application is as follows:

[0007] include:

[0008] The box contains a cavity;

[0009] A partition plate is disposed in the cavity and separates the cavity into a second cavity for containing the drug, and a hole communicating with the cavity is provided at the bottom;

[0010] An elastic element is elastically disposed on the outside of the partition plate, and the elastic direction is in the same direction as the hole axis.

[0011] The movable block is mounted on the elastic element and has holes passing through it into the cavity;

[0012] The spiral blades are mounted on the elastic element and are coaxially arranged with it.

[0013] A threaded column, fixed on a movable block, has at least two threaded grooves extending helically along its long side.

[0014] A ball bearing rod is disposed on the partition plate and extends into the threaded groove, with the ball portion making rolling contact with the threaded groove;

[0015] When the threaded column is pressed, the threaded column spirals down and pushes the movable block to misalign with the hole, creating a gap for the drug to pass through;

[0016] The threaded column reciprocates within the cavity of the housing under pressure and the action of the elastic element.

[0017] Preferably, the elastic element is a helical spring and a straight rod located in the inner ring of the helical spring and connected to the movable block, with both ends of the helical spring respectively disposed between the partition plate and the movable block.

[0018] Preferably, the bottom of the movable block is provided with a conical guide surface, and the cone angle of the conical guide surface is 30-45 degrees.

[0019] Preferably, the edge of the hole is provided with a bidirectional chamfer, the chamfer includes an upper 45-degree chamfer and a lower 30-degree chamfer, and the contact surface between the movable block and the hole is provided with a matching spherical transition portion.

[0020] Preferred options also include:

[0021] A limiting ring is set on the partition plate and encircles the threaded column.

[0022] A pressing plate is provided at the end of the threaded post that extends out of the box and is rotatably connected to it.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] In the scheme of this application:

[0025] To address the problem of uneven drug mixing within the device in existing technologies, this application employs a threaded rod that rotates under the constraint of a ball bearing rod during the pushing process. The spiral rotational force is collected by an elastic element and, after the hand-held force dissipates, drives the spiral blades to rotate again. This ensures that the drug solution mixes evenly with the water during the opening of the container, guaranteeing a uniform bud-suppressing effect. Attached Figure Description

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] For an example, please refer to... Figure 1 , Figure 2 and Figure 3 A topping and bud-suppressing device for tobacco cultivation, comprising:

[0033] Box 1, comprising a cavity;

[0034] The partition plate 2 is set in the cavity and separates the cavity into a second cavity for the drug to be contained. The bottom is provided with a hole communicating with the cavity.

[0035] The elastic element 3 is elastically disposed on the outside of the partition plate 2, and the elastic direction is in the same direction as the hole axis.

[0036] The movable block 4 is mounted on the elastic element 3 and has a hole extending into the cavity;

[0037] The spiral blade 5 is mounted on the elastic element 3 and is coaxially arranged with it;

[0038] The threaded column 6 is fixed on the movable block 4 and has at least two threaded grooves 61 that extend spirally along the long side.

[0039] The ball rod 7 is disposed on the partition plate 2 and extends into the threaded groove 61, with the ball portion rolling in contact with the threaded groove 61.

[0040] When the threaded column 6 is pressed, the threaded column 6 spirals down and pushes the movable block 4 to misalign with the hole to form a gap for the drug to pass through;

[0041] When the threaded column 6 is subjected to pressure and the elastic element 3, it reciprocates in the cavity of the box 1;

[0042] During the use of the device, the liquid medicine is first added to the cavity formed by the partition plate 2. At this time, the movable block 4 covers the hole of the partition plate 2, causing the partition plate 2 and the movable block 4 to divide the box 1 into two chambers. The partition plate 2 encloses the liquid medicine chamber. When the pressing plate 9 is pressed, the pressing plate 9 causes the threaded column 6 to gradually spiral down along the threaded groove 61 under the restriction of the ball rod 7.

[0043] During this process, the elastic element 3 is subjected to downward pressure and spiral decomposition force, which gradually increases its elastic potential energy. At the same time, the movable block 4 will gradually move away from the hole position of the partition plate 2, allowing the liquid medicine to enter the box 1 through this hole. Meanwhile, the spiral blade 5 at the bottom rotates synchronously under the action of the straight rod in the elastic element 3 as the liquid medicine flows into the box 1, making the liquid medicine more evenly mixed.

[0044] After the pressure on the pressing plate 9 is released, the spiral spring pushes the movable block 4 and the threaded column 6 to rotate and lift, causing the spiral blade 5 to rotate during repeated up and down movements. This allows the liquid to mix more thoroughly with the water in the box 1, ensuring the overall concentration of the agent and thus effectively controlling the bud-suppressing effect.

[0045] The elastic element 3 is a helical spring and a straight rod located in the inner ring of the helical spring and connected to the movable block 4. The two ends of the helical spring are respectively set between the partition plate 2 and the movable block 4.

[0046] The axial elastic deformation of the helical spring provides a stable reset driving force, ensuring precise alignment between the movable block 4 and the hole and preventing drug leakage.

[0047] The bottom of the movable block 4 is provided with a conical guide surface 41, and the cone angle of the conical guide surface 41 is 30-45 degrees;

[0048] The inclined angle of the conical guide surface 41 is used to guide the uniform diffusion of the drug, reduce drug residue at the edge of the orifice, and reduce flow resistance.

[0049] The edge of the hole is provided with a two-way chamfer, which includes an upper 45-degree chamfer and a lower 30-degree chamfer. The contact surface between the movable block 4 and the hole is provided with a matching spherical transition part.

[0050] The combination of the bidirectional chamfer and the spherical transition section enables flexible contact between the movable block 4 and the hole, reducing frictional loss and improving sealing performance and the smoothness of opening and closing actions.

[0051] Also includes:

[0052] The limiting ring 8 is set on the partition plate 2 and is arranged around the threaded column 6;

[0053] The radial displacement of the threaded post 6 is constrained by the limiting ring 8 to prevent skewing during the helical motion and ensure stable meshing between the threaded groove 61 and the ball rod 7.

[0054] Pressing plate 9 is located at the end of threaded post 6 that extends out of box body 1 and is rotatably connected to it;

[0055] The pressing plate 9 provides an enlarged contact surface for applying force, and the linkage control of pressing and rotation is achieved through the rotating connection structure, which avoids jamming of the threaded column 6 during manual operation.

[0056] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
