DETAILED DESCRIPTION
[0029] Reference Figure 1-4 A film covering device for agricultural planting includes a support plate 1, movable wheels 2 are fixedly installed on the four corners of the bottom of the support plate 1, a push handle 3 is fixedly installed on one side of the top of the support plate 1, a mixing box 4 is provided on the top of the support plate 1, a mixing component 5 is provided in the mixing box 4, a spraying component 6 is fixedly installed on the bottom of the support plate 1, the spraying component 6 is connected to the mixing box 4, a film covering component 7 is provided on the rear side of the spraying component 6 at the bottom of the support plate 1, and a film pressing and covering component 8 is provided on the rear side of the film covering component 7.
[0030] With this design, first of all, the device integrates the functions of mixing, spraying, covering and pressing the film to cover the soil. It can complete nutrient solution mixing, spraying, covering and pressing the film to cover the soil in one operation, reducing equipment preparation and operation conversion time, and improving overall efficiency.
[0031] Secondly, the mixing component 5 in the mixing box 4 mixes the nutrient solution evenly, and is connected to the spraying component 6 to spray it accurately onto the soil, providing good nutrition and humidity conditions for the growth of seedlings, avoiding the problem of uneven nutrient solution concentration, and improving the survival rate and growth quality of seedlings.
[0032] Again, the covering component 7 makes the protective film cover the soil smoothly, reducing wrinkles and damage. The film pressing and covering component 8 further fixes the protective film, making it fit tightly with the soil and with a firm edge, able to resist damage from wind, rain, etc., ensuring the long-term stability of the film and playing the role of heat preservation, moisture retention, and weed prevention.
[0033] Finally, there are moving wheels 2 at the four corners of the bottom of the device and a push handle 3 on the top. The operator can easily push it to move in the farmland, reducing labor intensity and speeding up the film covering speed. It is especially advantageous for large-scale farmland planting and saves a lot of time and manpower.
[0034] The mixing assembly 5 includes a driving motor 51 fixedly mounted on the top of the mixing box 4 . The power output end of the driving motor 51 passes through the mixing box 4 and is transmission-connected to a rotating rod 52 . A plurality of mixing rods 53 are provided on the rotating rod 52 .
[0035] With this design, first, the drive motor 51 serves as a power source fixed on the top of the mixing box 4, providing stable power for the entire mixing process, and the power output end of the drive motor 51 passes through the mixing box 4 and is directly connected to the rotating rod 52. This design reduces the energy loss in the intermediate transmission link and ensures that the rotating rod 52 can obtain continuous, stable and sufficient power to drive the mixing rod 53.
[0036] Secondly, the multiple mixing rods 53 provided on the rotating rod 52 greatly increase the contact area with the mixed liquid, so that during the rotation of the rotating rod 52, these mixing rods 53 stir the mixed liquid from different positions and angles. They cooperate with each other to break the stratification phenomenon and local uneven concentration that may exist in the mixed liquid.
[0037] A feed port 54 is formed through the top of the mixing box 4 .
[0038] With this design, first, the feed port 54 at the top allows the operator to conveniently put various materials directly into the mixing box 4 without the need for a complex feeding device, reducing equipment costs and operating difficulty, and making the operation simple and intuitive when adding powder additives, liquid nutrient solution and other materials.
[0039] Secondly, the top feed port 54 allows the operator to observe the liquid level or material accumulation in the box when feeding. When adding multiple ingredients, the amount of each material can be accurately controlled to ensure the accurate mixing ratio, which helps to improve the quality and stability of the mixed liquid. For example, when preparing nutrient solution, it can ensure that each element enters according to the predetermined ratio.
[0040] Thirdly, top feeding can greatly avoid material splashing. The liquid falls vertically under the action of gravity, reducing the possibility of splashing due to impact force. It can also prevent powder or granular materials from spilling outside, reducing waste and environmental pollution.
[0041] The spray assembly 6 includes a water distribution box 61 fixedly installed below the support plate 1 , and two sides of the water distribution box 61 are symmetrically fixedly connected with connecting blocks, and the top of the connecting block is fixedly connected to the support plate 1 .
[0042] A connecting pipe 62 is fixedly connected to the outer wall of one side of the water distribution box 61 , and the other end of the connecting pipe 62 passes through the support plate 1 and is fixedly connected to the mixing box 4 .
[0043] A water pump 63 is fixedly embedded in the water distribution tank 61 . A water inlet end of the water pump 63 is fixedly connected to a suction pipe (not shown in the figure), and the suction pipe is fixedly connected to the water distribution tank 61 .
[0044] The water outlet of the water pump 63 is fixedly connected to a water distribution plate 64 , and a plurality of nozzles 65 are fixedly connected to the bottom of the water distribution plate 64 .
[0045] With this design, first, the connecting pipe 62 directly connects the water distribution tank 61 and the mixing tank 4, forming an efficient conveying path and reducing the liquid conveying resistance, so that the nutrient solution can flow smoothly from the mixing tank 4 into the water distribution tank 61 under the action of gravity and the suction of the water pump 63, without the need for complex pipelines and additional devices, thereby improving the conveying efficiency and ensuring the liquid supply for the spraying operation; at the same time, its good sealing can prevent liquid leakage, avoid liquid waste and environmental pollution, and also prevent effects on the concentration of the nutrient solution, which is extremely critical to ensuring the quality and effect of spraying, especially when using special liquids.
[0046] Secondly, the water distribution plate 64 at the water outlet end of the water pump 63 has the function of evenly distributing the liquid. It can disperse the liquid delivered by the water pump 63 to the connection parts of each nozzle 65, prevent local accumulation of liquid or uneven flow of the nozzle 65, thereby ensuring uniform spraying; in addition, the multiple nozzles 65 at the bottom of the water distribution plate 64 work together to greatly increase the coverage area. Each nozzle 65 can cover a certain area, which can reduce omissions and uneven spraying, and can well meet the needs of agricultural irrigation, fertilization, plant protection, etc.
[0047] The film laminating assembly 7 includes a film laminating box 71 fixedly mounted on the bottom of the support plate 1 . The film laminating box 71 is a hollow structure with one end open. A film outlet 73 is provided at the bottom of the film laminating box 71 .
[0048] A rotating shaft 72 is rotatably provided on the inner side wall of the film laminating box 71 , and a film laminating roll is sleeved on the rotating shaft 72 . The free end of the film laminating roll passes through the film outlet 73 and extends to the outside of the film laminating box 71 .
[0049] With this design, first of all, the hollow structure of the laminating box 71 creates a relatively closed space for the laminating roll, which can prevent dust, debris, and moisture from damaging the protective film. It can avoid wind and sand erosion when stored in the open air, extending its life, and reducing scratches and damage, so that the protective film is in good condition before use, reducing costs and increasing the success rate of laminating. At the same time, this design facilitates the installation and disassembly of the laminating roll on the rotating shaft 72, and the operator can operate in a stable space to improve efficiency, and the laminating roll can be limited during operation to ensure that the protective film is smoothly unfolded.
[0050] Secondly, the rotating shaft 72 rotates on the inner wall of the film coating box 71, providing stable support for the rotation of the film coating roll, ensuring that it rotates along a fixed axis, reducing the problem of protective film unfolding caused by unstable rotation, and ensuring the continuity of the film coating even if the equipment moves on uneven ground; the protective film is pulled out from the film coating roll and passes through the film outlet 73 at the bottom of the box. The pulling path is clear and orderly, and the size and position of the film outlet 73 can be optimized, which can avoid the protective film from being subjected to additional resistance or extrusion, so that the protective film can cover the soil evenly and evenly, improve the quality of the film coating, and facilitate subsequent agricultural production operations.
[0051] The film-pressing and soil-covering assembly 8 includes two electric telescopic rods 81 symmetrically fixedly installed at the bottom of the support plate 1 , and the telescopic ends of the two electric telescopic rods 81 are fixedly installed with the same roller pressing box 82 , and the roller pressing box 82 is rotatably connected with a pressing roller 83 inside.
[0052] Two covering plates 84 are symmetrically provided on both sides of the roller press box 82 . A mounting block 85 is fixedly mounted on the top of each covering plate 84 . The top of the mounting block 85 is fixedly connected to the support plate 1 .
[0053] This design can firstly adjust the distance between the pressing roller 83 and the ground by controlling the extension and retraction of the electric telescopic rod 81 according to the film material, thickness and soil flatness, ensure appropriate pressure, make the film fit closely to the soil, and avoid film covering problems.
[0054] Secondly, in farmlands with different terrains, the electric telescopic rod 81 can adapt to the undulations of the ground, ensuring that the pressing roller 83 is in proper contact with the ground, so that the film is rolled evenly, improving the feasibility and effect of film covering under complex terrain.
[0055] Again, the covering plate 84 is fixed on the support plate 1 and is located on both sides of the roller pressing box 82. It can cover the soil on both sides of the edge of the film while the pressing roller 83 compacts the film, ensuring that the edge of the film is covered with soil in a timely and stable manner, thereby enhancing the stability of the film.
[0056] Finally, the integration of soil covering and film pressing functions reduces additional equipment or manual processes, shortens film covering operation time, and facilitates the rapid completion of film covering on large areas of farmland.
[0057] When the device needs to be used, water and materials are first placed into the mixing box 4 through the feed port 54, and the drive motor 51 is started. The output end of the drive motor 51 drives the rotating rod 52 to rotate, and the rotating rod 52 drives the mixing rod 53 to rotate. The mixing rod 53 mixes and stirs the materials and water in the mixing box 4 to turn them into a nutrient solution.
[0058] Then, the support plate 1 is moved by pushing the push handle 3, and the support plate 1 drives the moving wheel 2 to rotate, thereby moving the device to the specified position, and then the protective film is manually pulled out and one side of it is pressed with soil.
[0059] Then start the water pump 63, start the water pump 63, and start working. The water inlet end of the water pump 63 draws liquid from the water distribution tank 61 through the suction pipe. Since the water distribution tank 61 is connected to the mixing tank 4 through the connecting pipe 62, the mixed liquid in the mixing tank 4 flows into the water distribution tank 61 through the connecting pipe 62 under the suction force of the water pump 63.
[0060] After the water pump 63 pressurizes the extracted nutrient solution, the liquid is transported to the water distribution plate 64 through the water outlet, and finally sprayed out from multiple nozzles 65 connected to the bottom of the water distribution plate 64.
[0061] At the same time, the device is pushed to move. When the device moves, the film box 71 also moves with the movement of the device. Due to the movement of the device, the film roll is gradually unfolded through the rotation of the rotating shaft 72 under the action of gravity and friction with the ground. The protective film is continuously pulled out from the film outlet 73 at the bottom of the film box 71 and covers the surface of the soil passing by.
[0062] At the same time, the electric telescopic rod 81 is started, and the electric telescopic rod 81 drives the roller pressing box 82 to move downward, and the roller pressing box 82 drives the pressing roller 83 to move, so that the pressing roller 83 gradually approaches and contacts the laid protective film, pressing the protective film tightly against the soil surface, making it fit more closely with the soil. When the device moves, it will drive the mounting block 85 to move, and the mounting block 85 drives the covering plate 84 to move. While the pressing roller 83 rolls the protective film, as the equipment moves, the mounting blocks 85 on both sides move, and the mounting block 85 drives the covering plate 84 to move. The covering plate 84 shovels the soil on the ground and covers the edge of the protective film to fix the protective film.
[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
