Description

Technical Field

[0001] This utility model relates to a geotextile laying device and belongs to the field of geotextile laying technology. Background Technology

[0002] Geotextile laying is crucial in numerous engineering projects, including water conservancy, transportation, and environmental protection. Currently, geotextile laying relies heavily on manual operation or simple mechanical assistance. Controlling the tightness of the geotextile during laying remains a challenge. Manual adjustment makes it difficult to ensure the geotextile maintains proper tightness throughout the process, often resulting in either looseness or excessive tightness. Looseness can lead to wrinkles, affecting project quality, while excessive tightness can cause tearing, reducing its protective and reinforcing properties.

[0003] Chinese patent document CN209652903U discloses a geotextile laying device. In this device, the geotextile with rollers is first connected to a rotating shaft, then the geotextile is fixed in the initial laying position. Pulling the frame forward causes the rotating shaft and rollers to rotate together, unfolding the geotextile. While this method reduces the labor intensity of workers, it is still difficult to control the tightness of the geotextile during laying, making it difficult to ensure that the geotextile maintains appropriate tightness throughout the process. Looseness or excessive tightness can still occur, resulting in unsatisfactory laying results. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a geotextile laying device that facilitates control over the tightness of the geotextile and achieves good laying results.

[0005] The technical solution of this utility model is as follows:

[0006] A geotextile laying device includes a frame, wherein:

[0007] The frame is equipped with a roll shaft that is axially fixed and circumferentially rotatable for winding geotextile. The bottom of the frame is equipped with a pressing roller for pressing the geotextile onto the surface to be laid when the geotextile is unrolled. The pressing roller and the roll shaft are arranged in parallel.

[0008] A guide roller is arranged parallel to the roll shaft and the pressure roller. When the geotextile is unwound, it extends through the guide roller to the bottom of the pressure roller. The frame is equipped with a motor for driving the roll shaft to rotate to wind or unwind the geotextile. The motor is connected to one end of the roll shaft via a belt. The bottom of the frame is equipped with movable wheels via a wheel frame.

[0009] Furthermore, the guide roller includes two first guide rollers and second guide rollers respectively arranged at the top and bottom. A positioning plate is provided on the frame between the first guide rollers and the second guide rollers. The positioning plate has a positioning groove for the geotextile to pass through. When the geotextile is unwound, it extends sequentially through the upper side of the first guide roller, the positioning groove, and the lower side of the second guide roller to the bottom of the pressing roller.

[0010] Furthermore, the angle between the geotextile and the horizontal plane between the fabric roll shaft and the first guide roller is 8-10 degrees;

[0011] And / or, the angle between the geotextile between the first guide roller and the second guide roller and the horizontal plane is 75-85 degrees.

[0012] Furthermore, at least one side of the pressing roller is provided with a heating roller for heating and melting the edge of the geotextile during unwinding and for splicing adjacent geotextiles, and the frame is provided with a heating roller switch to control the start and stop of the heating roller.

[0013] Furthermore, the frame includes a frame body and four support legs located at the four corners of the frame body. A pair of first fixing plates extending inward are symmetrically provided on the inner bottom of the two support legs away from the fabric roll shaft. Each first fixing plate is provided with a pair of second fixing plates extending downward. The heating roller is assembled between the pair of second fixing plates, and the pressing roller is assembled between the two second fixing plates on the innermost side of the pair of first fixing plates.

[0014] Furthermore, the heating rollers are all coaxially assembled with the pressing rollers.

[0015] Furthermore, a pair of vertical support frames are symmetrically provided on both sides of the frame, and the fabric roll shaft is axially fixed and circumferentially rotatable between the pair of vertical support frames.

[0016] Furthermore, an electrical box is provided on the positioning plate on one side of the fabric roll shaft. The motor and the heating roller are both connected to the electrical box via wires. The frame is provided with a channel for the power supply line.

[0017] And / or, the number of the movable wheels is four, and each is located at the bottom of its respective support foot.

[0018] Furthermore, a pair of handles are fixed to the outer side of the frame below the fabric roll shaft for easy operation.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model employs a roll-up shaft, a pressure roller, and a guide roller. During the unwinding of the geotextile, the geotextile is guided by the guide roller and then pressed onto the surface to be laid by the pressure roller. The guide roller and pressure roller allow for stretching and flattening of the geotextile, enabling convenient and precise real-time control of its tension. This avoids wrinkles, looseness, or excessive tightness during unwinding, improving the flatness of the geotextile laying and ensuring that the geotextile fully performs its protective and reinforcing functions in various projects. It achieves high efficiency and convenience in laying geotextiles on road sections, eliminating the need for manual secondary adjustments by workers, effectively reducing the labor intensity of workers, and improving the efficiency and quality of geotextile laying, resulting in a good laying effect.

[0021] 2. The design of the heating roller in this utility model enables the geotextile laying device to not only lay geotextiles, but also to heat-melt connect two adjacent geotextiles, reducing secondary work, improving laying efficiency, and completing the laying and connection of geotextiles in one laying with good laying effect.

When the geotextile 1 is unwound, it extends through the guide roller to the bottom of the pressure roller 2. The frame 5 is equipped with a motor 13 for driving the roll shaft 6 to rotate to wind or unwind the geotextile 1. The motor 13 is connected to one end of the roll shaft through a belt 12. The bottom of the frame 5 is equipped with a movable wheel 10 through a wheel frame 11.

[0036] The guide rollers include two first guide rollers 9 and second guide rollers 14, which are respectively arranged at the top and bottom. A positioning plate 15 is provided on the frame 5 between the first guide rollers 9 and the second guide rollers 14. The positioning plate 15 has a positioning groove 151 for the geotextile 1 to pass through. When the geotextile 1 is unwound, it extends sequentially from the upper side of the first guide roller 9, the positioning groove 151, and the lower side of the second guide roller 14 to the bottom of the pressing roller 2.

[0037] The angle between the geotextile 1 between the roll shaft 6 and the first guide roller 9 and the horizontal plane is 8-10 degrees.

[0038] And / or, the angle between the geotextile 1 between the first guide roller 9 and the second guide roller 14 and the horizontal plane is 75-85 degrees.

[0039] Both sides of the pressing roller 2 are provided with heating rollers 3 for heating and melting the edges of the geotextile 1 when it is unrolled and for splicing adjacent geotextile 1. The frame 5 is provided with heating roller switches 4 connected to the heating rollers 3 to independently control the start and stop of the heating rollers.

[0040] The frame 5 includes a frame body 20 and four support legs 19 located at the four corners of the lower side of the frame body 20. A positioning plate 15 is fixedly installed on the upper part of the frame body. A pair of first fixing plates 16 extending inward are symmetrically provided on the inner bottom of the two support legs 19 away from the fabric roll shaft 6. Each first fixing plate 16 is provided with a pair of second fixing plates 17 extending downward. The heating roller 3 is assembled between the pair of second fixing plates 17. The pressing roller 2 is assembled between the two innermost second fixing plates 17 of the pair of first fixing plates 16.

[0041] The frame 20, positioning plate 15, and support leg 19 are manufactured as a single piece.

[0042] The heating rollers 3 are all coaxially assembled with the pressing rollers 2.

[0043] The frame 5 has a pair of vertical support frames 18 symmetrically arranged on both sides, and the cloth roll shaft 6 is axially fixed and circumferentially rotatable between the pair of vertical support frames 18.
