Description

Technical Field

[0001] This utility model belongs to the field of tobacco planting technology, and in particular relates to a moisture-retaining substrate covering device for the roots of tobacco seedlings before transplanting. Background Technology

[0002] To improve the survival rate of tobacco seedlings after transplanting, existing technologies include methods such as digging large pits (tobacco holes), watering heavily, and laying mulch, as well as transplanting in wells or cellars to ensure the seedlings retain warmth and moisture after transplanting. There are also methods that use specially formulated moisture-retaining substrates to cover the roots of the seedlings to enhance their drought and salt resistance. However, the latter method primarily relies on manually wrapping the moisture-retaining substrate around the seedling roots. This method is inefficient, wastes a lot of materials, and the uneven thickness of the coating layer leads to unsatisfactory moisture retention. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a moisture-retaining substrate coating device for the roots of tobacco seedlings before transplanting. This utility model has a simple structure and can quickly and quantitatively obtain the moisture-retaining substrate and shape it into a coating layer of uniform thickness, so that the moisture-retaining substrate can effectively improve the moisture retention effect of the tobacco seedling roots.

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

[0005] A moisture-retaining substrate covering device for the roots of tobacco seedlings before transplanting includes a hopper with a square discharge frame connected to the bottom. The discharge frame has notches on opposite side walls, and grooves are formed at the same height on the side walls on both sides of the notches. A sliding rod parallel to the discharge frame slides in cooperation with the corresponding groove.

[0006] A sealing plate for covering the discharge frame and a material tray for receiving the moisturizing substrate after aligning with the discharge frame are integrally connected sequentially between the two slide rods along the length direction.

[0007] Preferably, the top surfaces of both ends of the slide rod are provided with limiting posts vertically, and the sealing plate is set against the top wall of the notch.

[0008] Preferably, the top wall of the discharge frame extending downwards towards the notch of the material tray is integrally provided with a scraper; the material tray includes a horizontally arranged bottom plate, two parallel tray walls that are fixedly connected to a slide rod, and a surrounding plate located below the side of the sealing plate and fixedly connected to the two tray walls, the gap between the surrounding plate and the sealing plate forming the discharge port;

[0009] Preferably, the top surface of the enclosure plate is flush with the bottom surface of the scraper plate.

[0010] Preferably, the bottom of the two disc walls are provided with horizontally extending positioning slides and limiting grooves at the same height. The limiting grooves are located close to the surrounding plate, and the positioning slides are located away from the surrounding plate and extend to the end face of the disc wall.

[0011] The base plate is provided with cylindrical sliders on both sides, which slide in conjunction with the positioning slide and the limiting groove.

[0012] Preferably, the bottom plate is also provided with a side plate perpendicularly on the side away from the surrounding plate.

[0013] The working process of this utility model is as follows:

[0014] First, the utility model is moved horizontally so that the slide bar moves along the slide groove until the corresponding limiting post contacts the outer wall of the discharge frame. At this moment, the material tray is aligned with the discharge frame and the moisturizing substrate in the discharge frame falls in and fills the material tray.

[0015] Then, the device is pulled in the opposite direction until the limiting post at the other end of the slide bar contacts the outer wall of the discharge frame. At this moment, the material tray moves out of the discharge frame's range, and the sealing plate completely covers the discharge frame to prevent material leakage. During this process, material inside the tray that exceeds the material level of the surrounding plate is scraped off by the scraper. The scraped material is discharged from the discharge port and falls into the collection device below for recycling. This ensures that the material layer thickness inside the tray meets the requirements.

[0016] Finally, pull the bottom plate outward relative to the plate wall, so that the slider of the bottom plate away from the surrounding plate moves out of the positioning slide. Then, the bottom plate flips downward relative to the limiting groove, and the roots of the tobacco seedlings with rhizosphere substrate are placed on top of the material layer held on the bottom plate. Then, the material layer wraps around the roots of the tobacco seedlings to complete the wrapping operation.

[0017] The moisturizing matrix used in this application is composed of water-absorbing gel (sodium polyacrylate or starch-based polymer material) and conventional soil in a weight ratio of 1:5. It has a certain viscosity and the coating layer thickness is 5-10cm (that is, when the bottom plate is horizontal, the distance between its top surface and the top surface of the surrounding plate is 5-10cm).

[0018] This coating 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.

[0019] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure and can quickly and quantitatively obtain the moisturizing matrix and shape it into a uniform thickness coating layer, so that the moisturizing matrix can effectively improve the moisturizing effect of tobacco seedling roots.

[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 1-5 As shown, a moisture-retaining substrate covering device for the roots of tobacco seedlings before transplanting includes a hopper 1 with a square discharge frame 2 connected to the bottom. The discharge frame 2 has notches 21 on its opposite side walls, and grooves 22 are opened at the same height on the side walls on both sides of the notches 21. A sliding rod 3 arranged parallel to the discharge frame slides in cooperation with the corresponding groove 22.

[0027] The top surfaces of both ends of the slide rod 3 are vertically provided with limiting posts 31, and the two slide rods 3 are integrally connected in sequence along the length direction to a sealing plate 5 for covering the discharge frame 2 and a material tray for receiving the moisturizing substrate after aligning with the discharge frame:

[0028] The sealing plate 5 is set against the top wall of the notch 21, and the top wall of the discharge frame 2 facing the notch of the material tray is integrally provided with a scraper 23.

[0029] The material tray includes a horizontally arranged base plate 42, two parallel tray walls 41 fixedly connected to a sliding rod, and a surrounding plate 43 located below the side of the sealing plate 5 and fixedly connected to the two tray walls. The top surface of the surrounding plate 43 is flush with the bottom surface of the scraper plate 23, and the gap between the surrounding plate 43 and the sealing plate 5 forms a discharge port 6. A side plate 44 is also vertically arranged on the side of the base plate 42 away from the surrounding plate 43. In the horizontal state, the top surface of the base plate 42, together with the surrounding plate 43, the side plate 44 and the tray walls 41, forms a space for accommodating materials.

[0030] The bottom of the two disk walls 41 are provided with horizontally extending positioning slides 47 and limiting grooves 46 at the same height. The limiting grooves 46 are located close to the surrounding plate 43, and the positioning slides 47 are located away from the surrounding plate 43 and extend to the end face of the disk wall 41. The bottom plate 42 is provided with cylindrical sliders 45 on both sides, which slide in cooperation with the positioning slides 47 and limiting grooves 46.

[0031] The working process of this utility model is as follows:

[0032] First, the present invention is moved horizontally so that the slide bar 3 moves along the slide groove 22 until the corresponding limiting post 31 contacts the outer wall of the discharge frame 2. At this moment, the material tray is aligned with the discharge frame 2 and the moisturizing substrate in the discharge frame 2 falls into and fills the material tray.

[0033] Then, the device is pulled in the opposite direction until the limiting post 31 at the other end of the slide bar 3 contacts the outer wall of the discharge frame 2. At this moment, the material tray moves out of the range of the discharge frame 2, and the sealing plate 5 touches the scraper plate 23 and completely covers the discharge frame 2 to prevent material leakage. During this process, the material inside the material tray that is higher than the material level of the surrounding plate 43 will be scraped off by the scraper plate 23. The scraped material is discharged from the discharge port 6 and falls into the collection device below for recycling. In this way, the thickness of the material layer 7 in the material tray meets the requirements.

[0034] Finally, pull the bottom plate 42 outward relative to the plate wall 41, so that the slider 45 of the bottom plate 42 away from the surrounding plate moves out of the positioning slide 47, and then the bottom plate 42 flips downward relative to the limiting groove 46, so that the roots of the tobacco seedlings with rhizosphere substrate are placed on the material layer 7 contained in the bottom plate 42, and then the material layer wraps around the roots of the tobacco seedlings to complete the wrapping operation.

[0035] The moisturizing matrix used in this application is composed of water-absorbing gel (sodium polyacrylate or starch-based polymer material) and conventional soil in a weight ratio of 1:5. It has a certain viscosity and the coating layer thickness is 5-10cm (that is, when the bottom plate is horizontal, the distance between its top surface and the top surface of the surrounding plate is 5-10cm).

[0036] This coating 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.
