Description

Technical Field

[0001] This invention relates to the field of weed control fabric, and more particularly to a biodegradable weed control fabric for forest seedling cultivation. Background Technology

[0002] Weed control fabric, also known as weed-control fabric, weed-covering fabric, or weed-covering fabric, works by blocking light to prevent weeds from photosynthesizing, thus achieving the purpose of weed control. The main types of weed control fabric on the market are plastic woven fabric and non-woven fabric. Because it adopts a light-blocking physical weed control method, it largely eliminates the pollution hazards of herbicides, making it a safe and reliable weed control method. Existing weed control fabrics cannot be pressed down at the edges and are simply positioned by inserting poles. They are easily lifted by strong winds. Furthermore, existing weed control fabrics are not easy to fold and store after use, making transportation inconvenient. Therefore, we propose a biodegradable weed control fabric for forest seedling cultivation. Summary of the Invention

[0003] Purpose of the Invention: The purpose of this invention is to provide a biodegradable weed control fabric for forest seedling cultivation, solving the problems of existing weed control fabrics where the edges cannot be effectively pressed together and the fabric is easily blown away by the wind due to the use of only sticks for positioning, thus affecting the weed control effect. It also possesses biodegradable properties, meeting the environmental protection requirements of forest seedling cultivation and avoiding pollution of the seedling soil and environment by plastic weed control fabric residue. Another purpose of this invention is to provide a biodegradable weed control fabric that is easy to fold and store, simplifying the disassembly and storage process after use, reducing storage volume, facilitating transportation and repeated use, reducing labor and transportation costs in the forest seedling process, and improving the practicality and convenience of the weed control fabric.

[0004] Technical solution: A biodegradable weed control fabric for forest seedling cultivation, comprising a weed control fabric body, an adjustment seat fixedly connected to the upper surface of the weed control fabric body, screws rotatably connected to both sides of the inner side of the adjustment seat via a rotating shaft, a threaded sleeve threaded onto the outer side wall of the screw, an adapter plate fixedly connected to the upper surface of the threaded sleeve, and a traction plate rotatably connected to the front and rear of the upper surface of the adapter plate via a rotating shaft; Pressure strips are provided on the upper surface of the weed control fabric body, both in front of and behind the adjustment seat; The lower surface of the traction plate is rotatably connected to the upper surface of the pressure strip via a rotating shaft.

[0005] Furthermore, positioning rods are provided at all four corners of the weed control fabric body.

[0006] Furthermore, a U-shaped frame is fixedly connected to the upper surface of the adjusting seat, and a rotating rod is rotatably connected to the inner upper surface of the U-shaped frame via a rotating shaft. A bevel gear is fixedly connected to the bottom end of the rotating rod.

[0007] Furthermore, bevel gears two are fixedly connected to the opposite ends of the two screws, and the outer sidewalls of the two bevel gears two are meshed with the outer sidewall of the bevel gear one.

[0008] Furthermore, a knob is fixedly connected to the top of the rotating rod.

[0009] Furthermore, multiple double-headed rotating parts are provided between the adjusting seat and the pressure strip. The inner front and inner rear sides of the double-headed rotating parts are rotatably connected to a traction rod via a rotating shaft. The end of the traction rod away from the double-headed rotating parts is rotatably connected to a concave rotating part via a rotating shaft. The opposite sides of the two concave rotating parts that are opposite to each other are fixedly connected to the opposite sides of the adjusting seat and the pressure strip, respectively.

[0010] Furthermore, a traction rope is fixedly connected between the bottom of the double-headed rotating component and the upper surface of the weed control fabric body.

[0011] Furthermore, multiple notches are provided on the opposite sides of the two pressure strips. A winding rod is rotatably connected to the inner side of the notch via a rotating shaft. A second traction rope is fixedly connected to the outer wall of the winding rod. A traction head is fixedly connected to the end of the second traction rope away from the winding rod. The bottom of the traction head is fixedly connected to the upper surface of the weed control fabric body.

[0012] Furthermore, two rollers are fixedly connected to the outer wall of the winding rod, and rubber rings are fixedly connected to the outer wall of the rollers. The outer wall of the rubber rings is in contact with the upper surface of the weed control fabric body.

[0013] Beneficial effects: Effectively achieves tight and fixed edge of weed control fabric, improves weed control stability. The device, through the cooperation of adjusting seat, screw, screw sleeve, traction plate and pressure strip, can drive the pressure strip to unfold towards the edge of the weed control fabric and tightly adhere to the soil surface by turning the knob; With the positioning rods at the four corners, a double positioning and fixing structure is formed, which completely solves the problem that the existing weed control cloth is only positioned by the rods and is easily lifted when the wind is too strong. It ensures that the weed control cloth always covers the seedling area flat, ensures the effect of shading and weed control, avoids weed growth due to the displacement of the weed control cloth, and further improves the reliability of weed control. The device, through the cooperation of a double-headed rotating component, a traction rod, a concave rotating component, and a traction rope, can automatically pull the weed control fabric body to fold when the pressure strip is relatively contracted. Meanwhile, the winding rod and the second traction rope on the pressure strip work together with the traction head to simultaneously wind up the second traction rope during the shrinking process of the pressure strip, pulling the edge of the weed control fabric to fold towards the pressure strip, realizing the quick and automatic folding and storage of the weed control fabric, greatly simplifying the disassembly and storage process, reducing the storage volume, facilitating subsequent transportation and repeated use, effectively reducing the labor input and transportation costs in the forest seedling process, and improving the ease of use of the device; Meeting environmental protection requirements and protecting seedling soil and the surrounding environment, this weed control fabric is made of biodegradable material. Compared with traditional plastic weed control fabric, it can naturally degrade after use, avoiding pollution of seedling soil, vegetation and the surrounding environment caused by plastic residue. It meets the core ecological and environmental protection requirements in the process of forest seedling cultivation, and achieves a balance between weed control function and environmental protection needs, which is in line with the concept of green agricultural development. The entire device is controlled by a knob for pressing, unfolding, and folding. The operation is simple and easy to understand, requiring no complicated tools or professional skills, making it easy for seedling workers to quickly get started. At the same time, the rotating connection structure of each component is reasonably designed and operates smoothly. It can be adapted to different sizes of forest seedling areas by splicing, making it highly adaptable and able to meet the needs of various forest seedling scenarios. The device's convenient folding and storage, along with its structural stability, allows the weed control fabric to be reused repeatedly. Compared to disposable weed control fabric, this significantly reduces the cost of weed control materials during the forest seedling cultivation process. At the same time, its biodegradable properties also avoid the disposal costs of waste weed control fabric, further enhancing the device's economy and practicality. Attached Figure Description

[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a biodegradable weed control fabric for forest seedling cultivation is provided, including a weed control fabric body 1. An adjustment seat 2 is fixedly connected to the upper surface of the weed control fabric body 1. Both sides of the inner side of the adjustment seat 2 are rotatably connected to a screw 3 via a rotating shaft. A screw sleeve 4 is threadedly installed on the outer side wall of the screw 3. An adapter plate 5 is fixedly connected to the upper surface of the screw sleeve 4. A traction plate 6 is rotatably connected to the front and rear of the upper surface of the adapter plate 5 via a rotating shaft. Pressure strips 7 are provided on the upper surface of the weed control fabric body 1, both in front of and behind the adjustment seat 2; The lower surface of the traction plate 6 is rotatably connected to the upper surface of the pressure strip 7 via a rotating shaft; Positioning rods 8 are provided at the four corners of the weed control fabric body 1; A U-shaped frame 9 is fixedly connected to the upper surface of the adjusting seat 2. A rotating rod 10 is rotatably connected to the inner upper surface of the U-shaped frame 9 via a rotating shaft. A bevel gear 11 is fixedly connected to the bottom end of the rotating rod 10. Both screws 3 are fixedly connected to bevel gears 12 at their opposite ends, and the outer walls of both bevel gears 12 mesh with the outer walls of bevel gears 11. A knob 13 is fixedly connected to the top of the rotating rod 10; The weed control fabric body 1 is made of biodegradable material; Rotate knob 13 to drive rotating rod 10 to rotate. Rotating rod 10 drives bevel gear 11 at the bottom to rotate synchronously. Since bevel gear 11 meshes with two bevel gears 12, when bevel gear 11 rotates, it drives the two bevel gears 12 and the corresponding screw 3 to rotate synchronously. When screw 3 rotates, it drives the outer screw sleeve 4 to move along the length of screw 3. Screw sleeve 4 drives the adapter piece 5 to move. The adapter piece 5 pulls the pressure strip 7 away from the adjusting seat 2 through the traction plate 6 until the pressure strip 7 is tightly attached to the edge of the weed control fabric body 1 and pressed against the soil surface. At this time, the weed control fabric body 1 is unfolded, and the edge of the weed control fabric body 1 is pressed and fixed to prevent the wind from lifting the weed control fabric body 1. Next, the weed control fabric body 1 is laid flat in the forest seedling area, and the four positioning rods 8 are inserted into the soil at the four corners of the weed control fabric body 1 to achieve positioning.

[0018] like Figure 7 As shown, multiple double-headed rotating parts 14 are provided between the adjusting seat 2 and the pressure strip 7. The inner front and inner rear sides of the double-headed rotating parts 14 are rotatably connected to the traction rods 15 via rotating shafts. The end of the traction rod 15 away from the double-headed rotating parts 14 is rotatably connected to the concave rotating parts 16 via rotating shafts. The opposite sides of the two concave rotating parts 16 that are opposite to each other are fixedly connected to the opposite sides of the adjusting seat 2 and the pressure strip 7, respectively. A traction rope 17 is fixedly connected between the bottom of the double-headed rotating part 14 and the upper surface of the weed control cloth body 1. When the device is not in use and is folded for storage, the two pressure strips 7 are moved closer to each other by hand using the knob 13. At this time, under the rotational connection of the concave rotating part 16 and the double-headed rotating part 14, the top of the traction rod 15 tilts upward and lifts the double-headed rotating part 14. At this time, the traction rope 17 will have an upward pulling effect on the weed control fabric body 1 between the pressure strip 7 and the adjusting seat 2, so that the weed control fabric body 1 can be automatically pulled and folded as the pressure strips 7 move relative to each other.

[0019] like Figure 4 As shown, multiple notches 18 are provided on the opposite sides of the two pressure strips 7. The inner side of the notch 18 is rotatably connected to the winding rod 19 via a rotating shaft. The outer wall of the winding rod 19 is fixedly connected to the second traction rope 20. The end of the second traction rope 20 away from the winding rod 19 is fixedly connected to the traction head 21. The bottom of the traction head 21 is fixedly connected to the upper surface of the weed control fabric body 1. Two rollers 22 are fixedly connected to the outer wall of the winding rod 19. A rubber ring 23 is fixedly connected to the outer wall of the rollers 22. The outer wall of the rubber ring 23 is in contact with the upper surface of the weed control fabric body 1. When the weed control fabric is finished and needs to be disassembled and stored, first pull out the four positioning rods 8, and turn the knob 13 in the opposite direction to make the pressure strip 7 retract towards the adjustment seat 2; At this time, the rubber ring 23 contacts the weed control cloth body 1, allowing the roller 22 to rotate during movement, thereby driving the winding rod 19 to rotate and winding the second traction rope 20. Under the connection of the traction head 21, the front and rear edges of the weed control cloth body 1 are pulled together with the relative movement of the pressure strip 7 and folded towards the pressure strip 7 to complete the storage and facilitate subsequent transportation. When unfolding for use, the retractor 19 rotates in the opposite direction to release the second traction rope 20, which will allow the weed control fabric body 1 to be laid flat and unfolded.

[0020] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
