Planting mulch holder for weed growth prevention

Abstract

This utility model discloses a planting mulch film fixing device for preventing weed growth, including a fixing plate and a clamp. This utility model employs friction strips, sliders, and pressure plates. When fixing the mulch film, personnel can first insert the fixing plate and support plate into the soil using ground nails. Then, the side of the mulch film can be inserted into the clamp, passing through multiple sets of friction strips and extending to the innermost position. The bending channel formed by the multiple sets of friction strips increases the difficulty of detaching the mulch film. Furthermore, when the mulch film is extended to the innermost position, it is squeezed and fixed by the pressure plate. Personnel can also adjust the height of the clamp according to the terrain and the tension of the mulch film, ensuring that different areas of the mulch film are within a suitable tension and height difference. This avoids excessive structural differences that could lead to gaps and uneven tension, affecting the coverage effect of the mulch film. It has the advantages of uniform fixing height, good fixing effect, and strong practicality.

Description

Technical Field

[0001] This utility model relates to the field of planting tools technology, specifically to a planting mulch film fixer for preventing weed growth. Background Technology

[0002] Two-color mulch film is a widely used mulch film material in agriculture. It performs multiple functions through its unique color design (usually silver and black) to improve crop growth efficiency and yield.

[0003] The existing publicly available technology, application number CN202021726615.X, describes a two-color mulch film for suppressing weeds. It consists of a transparent layer, an upper black fixing layer, and a lower black fixing layer. In use, the lower black fixing layer is opened and then bonded to the adhesive layer. This allows control over the light-transmitting area of ​​the white mulch film, which can be adjusted according to the actual planting conditions, thus expanding its application range. Furthermore, the black fixing layer is opaque, preventing weeds from photosynthesizing and thus suppressing weeds.

[0004] Currently, existing plastic film needs to be fixed in the field to prevent it from curling up and affecting its quality. Traditionally, this method involves using a pole to poke a hole in the film, wrapping it around the hole to tighten it, and then inserting the pole into the soil. However, this method is prone to problems, such as uneven tension in different areas, leading to curling in areas with less tension and breakage in areas with more tension, thus affecting the quality of the film. Uneven pressure on the film also creates gaps, increasing the risk of debris and pests entering, affecting crop growth and reducing the film's practicality. Overall, the effect is not ideal and there is room for improvement.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a planting mulch film fixer that prevents weed growth. It has the advantages of uniform fixing height, good fixing effect, and strong practicality, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution To achieve the advantages of uniform fixed height, good fixing effect, and strong practicality, the specific technical solution adopted by this utility model is as follows: A planting mulch film fixing device for preventing weed growth includes a fixing plate and a clamp. An adjustment groove is formed in the middle of one side surface of the fixing plate. A sliding rod is installed inside the adjustment groove. A slider is slidably connected to the outer periphery of the sliding rod. A clamp is fixedly installed at one end of the slider. A fastening groove is formed inside the clamp. Several sets of friction strips are staggered at both ends inside the fastening groove, and the length of the friction strips gradually increases. A pressure plate is installed at the innermost position of the fastening groove, and an adjustment rod is installed at the middle of the top of the pressure plate. One end of the adjustment rod passes through one side of the clamp.

[0008] Furthermore, a support plate is installed at an angle on the other side surface of the fixing plate, and several sets of ground nails are installed at the bottom of both the support plate and the fixing plate.

[0009] Furthermore, locking holes are provided on the surface of the fixed plate, the surface of the slide rod, the inner wall of the adjusting groove, the surface of the slider, the surface of the clamp, and the surface of the adjusting rod, and the locking holes are fixed by fasteners.

[0010] Furthermore, several sets of positioning scales are evenly provided on one side of the fixing plate.

[0011] Furthermore, a pointer is installed on one side of the fixture, and the pointer is located outside the positioning scale.

[0012] Furthermore, a two-color mulch film is fixed inside the fastening groove.

[0013] Furthermore, the top of the friction strip has an arc-shaped structure.

[0014] Furthermore, the top of the friction strip is wrapped with rubber.

[0015] (III) Beneficial Effects Compared with the prior art, this utility model provides a planting mulch film fixer to prevent weed growth, which has the following beneficial effects: This utility model employs friction strips, sliders, and pressure plates. When fixing the mulch film, personnel can first insert the fixing plate and support plate into the soil using ground nails, thereby improving the initial stability of the structure. Then, the side of the mulch film can be inserted into the clamp, passing through multiple sets of friction strips and extending to the innermost position. The bending channel formed by the multiple sets of friction strips increases the difficulty of detaching the mulch film, thus improving the fixing effect.

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a planting mulch film fixer for preventing weed growth is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the planting film fixing device for preventing weed growth according to an embodiment of the present invention includes a fixing plate 1 and a clamp 8. An adjustment groove 5 is provided in the middle of one side surface of the fixing plate 1. A sliding rod 4 is installed inside the adjustment groove 5. A slider 6 is slidably connected to the outer periphery of the sliding rod 4. A clamp 8 is fixedly installed at one end of the slider 6. A fastening groove 12 is provided inside the clamp 8. Several sets of friction strips 9 are installed alternately at both ends inside the fastening groove 12, and the length of the friction strips 9 gradually increases. A pressure plate 15 is installed at the innermost position of the fastening groove 12, and an adjustment rod 7 is installed at the middle of the top of the pressure plate 15. One end of the adjustment rod 7 passes through one side of the clamp 8. The fixing plate 1 and the adjustment groove 5: The fixing plate 1 is made of Q23 steel. 5. The steel plate is stamped and formed, with an adjustment groove 5 centered on one side surface. A sliding rod 4 is fixed in the groove by bolts, and the sliding rod 4 is parallel to the adjustment groove 5. Slider 6 and clamp 8: The slider 6 is an ABS plastic injection molded part with a through hole in the center, slidingly engaging with the sliding rod 4 (0.5mm gap). The clamp 8 (ABS plastic) is fixed to one side of the slider 6 by rivets. The clamp 8 can rise and fall along the sliding rod 4 with the slider 6 (adjustment range 0-200mm). Height adjustment accuracy: The gap between the slider 6 and the sliding rod 4 ensures the straightness of the clamp 8's rise and fall. Combined with the positioning scale 3 and pointer 11, multiple sets of clamps can achieve uniform height, avoiding wrinkles or gaps in the mulch film due to height differences. Ease of operation: Manually pushed. The height can be adjusted by slider 6, and it is fixed by locking hole 2 after adjustment, which improves efficiency compared with traditional non-gradient adjustment; Height adaptability: The adjustment range of 0-200mm can adapt to different terrains (such as slopes and depressions), ensuring that the mulch film adheres to the ground and reducing the space for weed growth; Fastening groove 12 and friction strips 9: The top of the clamp 8 has a fastening groove 12, and three sets of friction strips 9 (ABS plastic, with lengths of 5mm, 10mm and 15mm respectively, and a spacing of 5mm) are installed alternately on both sides of the groove. The top of the friction strips 9 is arc-shaped (radius 3mm) and the surface is covered with 1mm thick silicone rubber (Shore hardness 50A); Pressure plate 15 and adjusting rod 7: The innermost side of the fastening groove 12 is equipped with a pressure plate 15, which presses down on the mulch film. An adjusting rod 7 is welded to the center of the top of plate 15. The end of the rod passes through the top of clamp 8 and has a locking hole 2 (e.g., φ3mm). The position of pressure plate 15 is locked by M3 bolts. Anti-detachment mechanism: The friction strip 9 gradually changes length to form a "barbed" channel. The static friction coefficient between the mulch film and the rubber friction strip 9 increases. Combined with the pressure of pressure plate 15, the gripping force of a single clamp 8 on the mulch film is improved. Non-destructive fixing: The arc-shaped friction strip 9 + silicone wrapping prevents the edge of the mulch film from being scratched by sharp edges, solving the problem of traditional metal clamps 8 easily tearing the mulch film (reducing the damage rate). Reliable fixing: The double fixing of "friction strip 9 bending + pressure plate 15 pressing" reduces the mulch film detachment rate compared to the traditional method of only using soil pressure, ensuring long-term coverage.

[0022] like Figure 1 and Figure 3As shown, a support plate 14 is installed at an angle on the other side of the fixed plate 1. Several sets of ground nails 13 are installed at the bottom of both the support plate 14 and the fixed plate 1. The support plate 14 (Q235 steel plate) is fixed to the other side of the fixed plate 1 by welding. The support plate 14 and the fixed plate 1 form a 45° angle (to enhance the anti-overturning ability). Multiple sets of ground nails 13 (such as 5mm in diameter × 150mm in length, 30° tip cone angle, quenched HRC45) are welded to the bottom of both the fixed plate 1 and the support plate 14. Wind resistance stability: The 45° support plate 14 + multiple sets of ground nails 13 (soil penetration depth ≥100mm) form a triangular support structure, which improves the fixing effect. The support plate 14 distributes the force on the fixed plate 1, and the ground nails 13 penetrate deep into the soil to prevent lodging. It is suitable for use in windy areas (such as northern farmland).

[0023] like Figure 1 and Figure 2 As shown, locking holes 2 are provided on the surface of the fixing plate 1, the surface of the slide rod 4, the inner wall of the adjusting groove 5, the surface of the slider 6, the surface of the clamp 8, and the surface of the adjusting rod 7. The locking holes 2 are fixed by fasteners. The locking holes 2 and the fasteners: the fixing plate 1, the slide rod 4, the adjusting groove 5, the slider 6, the clamp 8, and the adjusting rod 7 all have φ4mm locking holes 2 (spaced 20mm), which are locked by M4 hand-tightening bolts (with anti-slip knobs). After locking, the displacement of the components is reduced. Locking reliability: the design of multiple locking holes 2 ensures that there is no loosening after adjustment, avoiding gaps in the mulch film due to loosening of the fixing device. The detachable fasteners make the fixing device reusable, reducing the cost compared to disposable plastic fixing devices.

[0024] like Figure 1 As shown, a number of positioning scales 3 are evenly provided on one side of the fixed plate 1. The positioning scales 3 and the pointer 11 are printed on one side of the fixed plate 1 along the direction of the adjustment groove 5 (unit mm, accuracy 1 mm, range 0-200 mm).

[0025] like Figure 1 and Figure 2 As shown, a pointer 11 is installed on one side of the clamp 8, and the pointer 11 is located outside the positioning scale 3. The pointer 11 (PVC material, 10mm long, with the tip pointing to the scale) is glued to the side of the clamp 8 near the fixing plate 1. The unified standard: the design of positioning scale 3 + pointer 11 reduces the deviation of the mulch film height when planting on a large area (such as 1 acre), and avoids uneven height caused by manual visual inspection.

[0026] like Figure 1 As shown, a two-color mulch film 10 is fixed inside the fastening groove 12. The two-color mulch film 10 is fixed by inserting its edge into the fastening groove 12, passing around the three sets of friction strips 9 in sequence to form an "S" shaped bending path, and finally being pressed by the pressure plate 15.

[0027] like Figure 1and Figure 2 As shown, the top of friction strip 9 has an arc-shaped structure.

[0028] like Figure 1 and Figure 2 As shown, the top of the friction strip 9 is wrapped with rubber; Install the fixing device: Arrange the fixing devices according to the planting row spacing (e.g., 50cm), insert the ground nail 13 vertically into the soil (100mm deep), ensure the fixing plate 1 is vertical, and simultaneously adjust the support plate 14 to make it in close contact with the ground to enhance stability; Fix the mulch film and adjust its height: Insert the edge of the two-color mulch film 10 into the fastening groove 12 of the clamp 8, push it in to the innermost side along the bending path of the friction strip 9 (ensure the mulch film is taut), rotate the adjusting rod 7 to press down the pressure plate 15 until the mulch film is pressed tight (the resistance feels significantly increased), fix the adjusting rod 7 through the locking hole 2, observe the pointer 11 and the positioning scale 3, and push the slider 6 to adjust the height of the clamp 8 (e.g., (Adjust to 50mm uniformly), after alignment, lock the slider 6 with fasteners; Large-area coordination: Repeat the above steps for adjacent fixing devices, ensure consistent height through positioning scale 3, uniform tension of the mulch film, check the adhesion of the mulch film to the ground (no obvious bulging), and ensure that the friction strip 9 and pressure plate 15 are not loose, then the installation is complete; Weed control effect: The tight coverage of the mulch film + black shading reduces the germination rate of weeds, reducing the cost of manual weeding; Fixing reliability: The dual fixing mechanism improves the stability of the mulch film and the coverage period; Through the synergy of height adjustment, multiple fixing and structural reinforcement, this fixing device solves the problems of "uneven height, easy fall-off, and poor weed control effect" of traditional mulch film fixing, making it easier to promote and use.

[0029] Working principle: In actual use, personnel can directly insert the fixing plate 1 into the corresponding area through the bottom ground nail 13, allowing the ground nail 13 to penetrate into the soil, thereby fixing the fixing plate 1. At the same time, the side of the fixing plate 1 is inclined with a support plate 14, which can improve the support strength of the fixing plate 1 and facilitate better use. Then, personnel can insert the side of the two-color mulch film 10 into the fastening groove 12 on the surface of the clamp 8. At this time, the mulch film will bend into the friction strip 9 multiple times. The contact friction of multiple sets of friction strips 9 can improve the fixing effect of the mulch film and reduce the probability of it coming off directly, making it easier to use. At the same time, when the mulch film moves to the innermost side, the pressing plate 15 can squeeze the mulch film. The fixing process further enhances the fixing effect. Personnel can then adjust the height of clamp 8 according to the surrounding terrain and the varying heights of the mulch films. This ensures that different positions of the mulch film are at the required height, preventing gaps caused by uneven heights and increasing the probability of external substances intruding. Adjusting the height also changes the tension on the mulch film, resulting in a more balanced tension and preventing uneven force from affecting the covering effect, thus facilitating better use. Furthermore, the dual-color mulch film 10 effectively blocks weeds through its different color areas, preventing weed growth and improving the overall weed control effect. The device as a whole has the advantages of uniform fixing height, good fixing effect, and strong practicality.
