Description

Technical Field

[0001] This utility model belongs to the field of tobacco planting technology, and in particular relates to a root moisturizing treatment device for tobacco seedlings before transplanting. Background Technology

[0002] Maintaining moisture retention in the rhizosphere soil of tobacco seedlings is a key technique for improving transplant survival rates. However, current techniques primarily rely on thoroughly watering the planting hole before transplanting and watering promptly afterward to prevent dehydration. While these methods increase humidity after transplanting, the soil moisture in the field cannot be directly transferred to the rhizosphere soil during the transplanting period. Therefore, some studies suggest wrapping the rhizosphere soil with a moisture-retaining material and transplanting it along with the seedlings into the planting hole. However, this wrapping method remains in the experimental stage and relies mainly on manual labor, resulting in low overall efficiency and poor adhesion between the moisture-retaining material and the rhizosphere soil, thus affecting practical application. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a root moisturizing treatment device for tobacco seedlings before transplanting. This utility model has a simple structure, is suitable for assembly line operations of wrapping moisturizing materials around the roots of tobacco seedlings, has a high degree of standardization, and provides a good wrapping effect.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A root moisturizing treatment device for tobacco seedlings before transplanting includes a workbench and two pressing plates on the workbench. The two pressing plates are in the form of bent plates with their ends facing each other and the outer wall of the bent part of one pressing plate is aligned with the inner wall of the bent part of the other pressing plate.

[0006] The two pressing plates are connected by a transmission mechanism, and a seedling platform is provided at the center of the distance between the two pressing plates.

[0007] Preferably, the transmission mechanism includes transmission plates respectively fixedly mounted on the back sidewalls of the two pressure plates, the two transmission plates being set at the same height and having internal threaded holes corresponding to one end in the same direction;

[0008] The screw has two threaded sections with opposite directions of rotation, and the two threaded sections are respectively screwed into the internal threaded holes of the corresponding transmission plates.

[0009] Preferably, the end of the screw is connected to the output end of the motor mounted on the workbench;

[0010] The other ends of the two transmission plates are respectively provided with through holes and the two through holes are slidably engaged with the guide rod. The guide rod is fixed with limiting flanges at both ends.

[0011] Preferably, a material collection frame is provided on the workbench surface outside the end point of the pressure plate's stroke.

[0012] Preferably, the seedling platform is a hollow cylindrical structure that fits with a pre-set through hole on the work platform with a gap, has an inwardly curved top, and extends through the through hole to the bottom of the work platform.

[0013] Preferably, a foot pedal is provided below the seedling platform, and a connecting rod coaxially fixed to the bottom surface of the seedling platform is connected to one end of the foot pedal. The other end of the foot pedal slides in cooperation with a limiting rod fixed to the bottom surface of the workbench through a preset through hole.

[0014] Preferably, a limiting plate is provided at the bottom end of the limiting rod, and a spring is sleeved on the limiting rod body between the limiting plate and the pedal.

[0015] The working process of this utility model is as follows:

[0016] The workbench of this utility model is designed to provide a working base for workers in a seated position, providing support for their hands and feet.

[0017] When not in operation, the top surface of the seedling platform is higher than the top surface of the pressure plate and is maintained in this state by the action of the spring;

[0018] During the work, the staff takes the tobacco seedlings out of the seedling tray and places them with the roots (the tobacco seedlings have well-developed lateral roots, which will remove the substrate, i.e. the root zone soil, from the seedling tray) facing down on the concave curved surface at the top of the seedling platform. (The concave curved surface can effectively prevent the tobacco seedlings from turning over. At the same time, a through hole can be made at the lowest point of the concave curved surface, so that some of the well-developed taproots of the tobacco seedlings can be inserted into the through hole. Of course, some substrate will also fall into the seedling platform from the through hole.)

[0019] Then, the staff fills the gap between the two pressing plates and the seedling platform with the moisture-retaining material (a large amount of moisture-retaining material is stacked in the material collection frame outside the pressing plate). After filling, the staff presses the pedal with their feet, which compresses the spring and causes the pedal to move vertically downward along the limit rod. This causes the seedling platform to move downward through the connecting rod. After the seedling platform moves downward, the blank space left by the seedling platform is filled with the roots of the tobacco seedlings. Then, the motor is turned on. The motor drives the two pressing plates to move in opposite directions through the screw and tightly presses the moisture-retaining material at the roots of the tobacco seedlings, while ensuring that the thickness of the moisture-retaining layer is relatively uniform throughout.

[0020] Finally, control the motor to reverse and drive the pressing plate to reset. After taking out the current tobacco seedling, release the pedal to allow the spring to drive the seedling platform to reset, and then proceed with the operation of the next tobacco seedling.

[0021] The guide rod ensures the stability of the pressure plate's movement and, through the limiting flange, keeps the two pressure plates in contact at their bent sections even at the maximum distance. The final thickness of the moisture-retaining layer is determined by the minimum distance between the two pressure plates, which can be adjusted by the distance between the pressure plates and the seedling platform, as well as the length of the bent section.

[0022] The moisture-retaining material used in this application is composed of a water-absorbing gel (sodium polyacrylate or starch-based polymer) and conventional soil in a 1:5 weight ratio, and has a certain viscosity. This moisture-retaining material can adsorb beneficial microorganisms through the porous structure of the gel material, thereby optimizing the root micro-ecological environment. At the same time, it can gradually release water through osmotic pressure difference and capillary action, maintaining the soil moisture of tobacco seedling roots at 60-80%. Moreover, it can be loaded with humic acid, trace elements, etc., to enhance the drought and salt resistance of tobacco seedlings.

[0023] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure, is suitable for assembly line operation of wrapping the roots of tobacco seedlings with moisturizing materials, has a high degree of standardization and good wrapping effect.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] like Figure 1 As shown, a root moisture retention treatment device for tobacco seedlings before transplanting includes a workbench 1 and two pressing plates 2 on the workbench 1. The two pressing plates 2 are in the form of bent plates with their ends facing each other vertically, and the outer wall of the bent part of one pressing plate 2 is aligned with the inner wall of the bent part of the other pressing plate 2. Two transmission plates 21 of equal height are respectively fixed on the back side walls of the two pressing plates 2. The two transmission plates 21 have corresponding internal threaded holes at their ends facing the same direction. The two internal threaded holes are respectively screwed into the threaded sections of the screw 24 with opposite directions of rotation. The end of the screw 24 is connected to the output end of the motor 25 on the workbench.

[0027] The other ends of the two transmission plates 21 are respectively provided with through holes and the two through holes are slidably engaged with the guide rod 22. The guide rod 22 is fixed with limiting flanges 23 at both ends.

[0028] A material collection frame 11 is provided on the workbench 1 outside the end point of the travel of the pressure plate 2. A seedling platform 3 is provided at the center of the distance between the two pressure plates 2. A limiting rod 12 is also vertically fixed on the bottom surface of the workbench 1. A limiting plate 13 is provided at the bottom end of the limiting rod 12.

[0029] The seedling platform 3 is a hollow cylindrical structure that fits with a pre-set through hole on the workbench 1 with a concave curved top and a bottom end that passes through the through hole to the bottom of the workbench 1. A connecting rod 31 is coaxially fixed on the bottom surface of the seedling platform 3. One end of the connecting rod 31 is connected to one end of the pedal 32. The other end of the pedal 32 slides with the limiting rod 12 through a pre-set through hole. A spring 14 is sleeved on the limiting rod 12 between the limiting plate 13 and the pedal 32.

[0030] The working process of this utility model is as follows:

[0031] The workbench 1 of this utility model is designed to provide a working base for workers in a seated position, providing support for their hands and feet.

[0032] In the non-working state, the top surface of the seedling platform 3 is higher than the top surface of the pressure plate 2, and is maintained in this state under the action of the spring 14;

[0033] During the work, the staff takes the tobacco seedlings out of the seedling tray and places them with the roots (the tobacco seedlings have well-developed lateral roots, which will remove the substrate, i.e. the rhizosphere soil, from the seedling tray) facing down on the concave curved surface at the top of the seedling platform 3. (The concave curved surface can effectively prevent the tobacco seedlings from turning over. At the same time, a through hole can be opened at the lowest point of the concave curved surface, so that some of the well-developed taproots of the tobacco seedlings can be inserted into the through hole. Of course, some substrate will also fall into the seedling platform 3 from the through hole.)

[0034] Then, the staff fills the gap between the two pressing plates 2 and the seedling platform 3 with the moisturizing material (a large amount of moisturizing material is stacked in the material collection frame outside the pressing plate). After filling, the staff presses the foot pedal 32, which moves the foot pedal 32 vertically downward along the limit rod 12 based on the compression spring 14. The foot pedal 32 moves downward along the limit rod 12 and moves the seedling platform 3 downward through the connecting rod 31. The blank space left after the seedling platform 3 moves downward is filled by the roots of the tobacco seedlings. Then the motor 25 is turned on. The motor 25 drives the two pressing plates 2 to move in opposite directions through the screw 24 and squeezes the moisturizing material tightly at the roots of the tobacco seedlings, while ensuring that the thickness of the moisturizing layer is relatively uniform.

[0035] Finally, control the motor 25 to reverse and drive the pressing plate 2 to reset. After taking out the current tobacco seedling, release the pedal 32 so that the spring 14 can drive the seedling platform 3 to reset. Then, the operation of the next tobacco seedling can be carried out.

[0036] The guide rod 22 ensures the stability of the movement of the pressure plate 2, and also ensures that the two pressure plates 2 remain in contact at their bent portions even at the maximum distance through the limiting flange 23. The final thickness of the moisture-retaining layer is determined by the minimum distance between the two pressure plates 2, which can be adjusted by the distance between the pressure plate 2 and the seedling platform 3, as well as the length of the bent portion.

[0037] The moisture-retaining material used in this application is composed of a water-absorbing gel (sodium polyacrylate or starch-based polymer) and conventional soil in a 1:5 weight ratio, and has a certain viscosity. This moisture-retaining material can adsorb beneficial microorganisms through the porous structure of the gel material, thereby optimizing the root micro-ecological environment. At the same time, it can gradually release water through osmotic pressure difference and capillary action, maintaining the soil moisture of tobacco seedling roots at 60-80%. Moreover, it can be loaded with humic acid, trace elements, etc., to enhance the drought and salt resistance of tobacco seedlings.
