[0044] Figures 1 to 3 The utility model shows an embodiment of a geotextile spreading device, which comprises a fixing frame 1, a telescopic frame 2, a supporting frame 3, a cloth pressing assembly 4, a spreading rod 5 and a spreading plate 6.

[0045] There are two telescopic frames 2, and the two telescopic frames 2 are respectively telescopically connected to the opposite sides of the fixed frame 1 in the direction of moving away from or approaching each other. There are two support frames 3, and the two support frames 3 are respectively connected to the two telescopic frames 2. The two support frames 3 are used to support the reels 7, and the reels 7 are used to wind the geotextile 8, and the geotextile 8 is wound between the opposite ends of the reels 7. The two support frames 3 are respectively used to support the opposite ends of the reels 7, and the reels 7 can rotate on the two support frames 3 to unfold the wound geotextile 8.

[0046] The cloth pressing assembly 4 includes a cloth pressing rod 41 and a connecting rod 42, wherein the connecting rod 42 is hinged on the fixing frame, the cloth pressing rod 41 is arranged on the connecting rod 42, and the cloth pressing rod 41 is used to press the reel 7. When the reel 7 is placed on the supporting frame 3, the cloth pressing rod 41 can press the geotextile 8 on the reel 7, limit the position of the reel 7, and make the reel 7 rotate around its own axis, stably without shaking, which is conducive to making the geotextile 8 unfold smoothly.

[0047] The cloth spreading rod 5 is connected to the fixed frame 1 and / or the telescopic frame 2, and the cloth spreading rod 5 is lower than the supporting frame 3. The cloth spreading plate 6 is arranged at the bottom of the fixed frame 1 and / or the telescopic frame 2, and the cloth spreading plate 6 is lower than the cloth spreading rod 5.

[0048] When the geotextile spreading device is working, it moves along the working surface where the geotextile needs to be laid, and the bottom of the spreading plate 6 is against the working surface. The two ends of the reel 7 are supported on two support frames 3 respectively. After the geotextile 8 on the reel 7 is unfolded, it passes around the spreading rod 5 below. The spreading rod 5 can stretch the geotextile 8 to flatten the geotextile 8 and avoid wrinkles. Then the geotextile 8 extends to the spreading plate 6 below the spreading rod 5, and the geotextile 8 passes the bottom of the spreading plate 6 and can be spread evenly on the working surface by the spreading plate 6.

[0049] According to the specific length of the reel 7, the relative positions of the two telescopic frames 2 can be adjusted, and the distance between the two support frames 3 can be changed to adapt to the length of the reel 7, so as to lay geotextiles of different widths.

[0050] The geotextile spreading device has a simple structure, low manufacturing cost, and is easy and convenient to use. It can reduce the labor intensity of laying geotextiles, improve construction efficiency, and can lay the geotextiles flat to ensure construction quality.

[0051] Specifically, the heights of the two support frames 3 are the same, and the reel 7 can be placed horizontally on the two support frames 3. The cloth pressing rod 41 and the cloth spreading rod 5 are parallel to the reel 7 on the support frame 3. The cloth pressing rod 41 can be connected to the fixed frame 1 through one or more connecting rods 42. Furthermore, the cloth pressing rod 41 and / or the cloth spreading rod 5 can be round rods, which can better fit with the geotextile 8. The geotextile 8 can fit on the surface of the cloth pressing rod 41 and the cloth spreading rod 5 and slide, which is conducive to smoothing the geotextile 8.

[0052] The cloth pressing assembly 4 is located above the support frame 3, and the cloth pressing rod 41 can be pressed on the reel 7 under the action of its own gravity, and the geotextile 8 pulls the reel 7 to rotate on the support frame 3 during the laying process. During the laying process, the diameter of the geotextile 8 wound on the reel 7 gradually decreases, and the cloth pressing rod 41 can always press on the geotextile 8. After the cloth pressing rod 41 is lifted, the reel 7 on the support frame 3 can be removed.

[0053] With the moving direction of the geotextile spreading device in operation as the front, the spreading rod 5 is located in front of the spreading plate 6, and the geotextile passes over the bottom of the spreading rod 5 from above the spreading rod 5, and then extends to the spreading plate 6 at the rear.

[0054] In some embodiments, Figure 1 As shown, the cloth pressing assembly 4 also includes an elastic member 43 connected between the fixing frame 1 and the connecting rod 42, and the cloth pressing rod 41 is configured to press the geotextile 8 on the reel 7 under the elastic force of the elastic member 43 to improve stability. The elastic member 43 can be a tension spring, an elastic rope, a torsion spring, etc. One end of the connecting rod 42 is hinged to the fixing frame 1 through a rotating shaft, and the axis of the rotating shaft is parallel to the cloth pressing rod 41.

[0055] In some embodiments, Figure 3As shown, the support frame 3 is provided with a groove 31 that matches the reel 7, and the end of the reel 7 can be matched in the groove 31 and rotate in the groove 31. The groove 31 can limit the position of the reel 7 and prevent the reel 7 from moving. The groove 31 can be an arc-shaped structure.

[0056] In some embodiments, the spreading rod 5 is a telescopic rod, and the opposite ends of the spreading rod 5 are respectively connected to two telescopic frames 2. By adjusting the relative positions of the two telescopic frames 2, the length of the spreading rod 5 can be adjusted at the same time, so that the spreading rod 5 is adapted to the length of the reel 7, so that geotextiles 8 of different widths can be laid.

[0057] In some embodiments, the laying board 6 is a rubber board with a certain elasticity. The laying board 6 is configured to be against the working surface where the geotextile is laid through the elasticity of the bottom, which can further flatten the geotextile and make the geotextile 8 close to the working surface. The laying board 6 can be arranged vertically or inclined.

[0058] The cloth-laying board 6 can be formed by arranging and splicing a plurality of rubber sheets in a transverse manner, a part of the rubber sheets is fixedly connected to the bottom of the fixed frame 1, and another part of the rubber sheets is fixedly connected to the bottom of the two telescopic frames 2. When adjusting the positions of the two telescopic frames 2, the length of the cloth-laying board 6 can be adjusted by increasing or decreasing the number of rubber sheets, so that the cloth-laying board 6 can adapt to the distance between the two telescopic frames 2.

[0059] In some embodiments, Figure 3 As shown, the fixing frame 1 includes a first cross beam 11 and a second cross beam 12 that are fixedly connected.

The first cross beam 11 and the second cross beam 12 can be connected by an upright fixing rod. The first cross beam 11 and the second cross beam 12 are hollow and have openings at their ends.

[0060] The telescopic frame 2 includes a first telescopic rod 21 and a second telescopic rod 22 that are fixedly connected. The first telescopic rod 21 is located above the second telescopic rod 22, and the two are parallel to each other. The first telescopic rod 21 and the second telescopic rod 22 can be connected by an upright fixed rod. One end of the first telescopic rod 21 is slidably inserted into the first crossbeam 11, and one end of the second telescopic rod 22 is slidably inserted into the second crossbeam 12. The first telescopic rod 21 and the second telescopic rod 22 slide synchronously.

[0061] Furthermore, if Figure 1 and Figure 2 As shown, the first crossbeam 11 and / or the second crossbeam 12 may be installed with set screws 13 near both ends, and the set screws 13 are used to fix the first telescopic rod 21 inserted into the first crossbeam 11 or the second telescopic rod 22 inserted into the second crossbeam.
