[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, an elastic bracket is provided to provide a certain elastic support for the guide roller. When the ground protection film is laid, it abuts against the guide roller. The elastic bracket can control the tension of the ground protection film at the bottom of the guide roller during laying, thereby facilitating the ground protection film to be laid evenly on the ground. When the ground protection film needs to be split, the guide roller is moved to the inside of the groove by the provided pressing rod. The two groups of guide rollers can tighten and fix the ground protection film at the top of the splitting groove, thereby facilitating the use of the splitting assembly to quickly and evenly split the ground protection film. The flat incision is also conducive to avoiding unnecessary material waste.

[0021] 2. In the present invention, two groups of U-shaped frames are symmetrically arranged, and the ground protection film to be laid slides between the two groups of U-shaped frames, which can prevent the ground protection film from deviating to both sides during laying, and further assist in the normal laying of the ground protection film. The top of the U-shaped frame also provides a positioning point for the splitting component. An adjusting screw is further provided to drive the push-pull rod and the first connecting rod to move. The first connecting rod can drive the column and the U-shaped frame to slide, and adjust the distance between the two groups of U-shaped frames, so that the device can efficiently adapt to ground protection films of different widths for use.

[0022] 3. In the present invention, a push-pull plate that can be pressed down is provided to drive the vertical rod, the mounting plate and the dividing knife to move. At the same time, the push-pull plate drives the second spring to be compressed. The push-pull plate slides left and right to drive the dividing knife at the bottom to quickly split the ground protection film. At the same time, the mounting plate can drive the connecting plate and the clamping rod to move through the second connecting rod. When the dividing knife is pressed down, it is convenient to realize the synchronous separation between the movable frame and the U-shaped frame. When the ground protection film is split, the movable frame moves to the inside of the U-shaped frame on the other side. The second spring is reset to automatically fix the movable frame and the dividing knife is recovered to the protective frame. This is beneficial to avoid the dividing knife scratching the ground protection film when the paving device is running, and also to avoid the tip of the dividing knife being damaged by splashing stones, thereby improving the actual service life of the dividing knife. The simple structure of the device is also conducive to practical and convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 8 In an embodiment of the present invention, a ground protection film splitter includes a mounting bracket 10, an elastic guide assembly 20, a limit assembly 30 and a splitting assembly 40. The mounting bracket 10 includes a supporting base plate 101 and supporting frames 102 welded to both ends of the supporting base plate 101. A splitting groove 11 is opened in the middle of the supporting base plate 101. Two groups of round rods 103 are welded between the tops of the two groups of supporting frames 102. The elastic guide assembly 20 includes an elastic bracket 201 slidably installed inside the supporting frame 102 up and down, and two groups of parallel guide rollers 202 are rotatably installed between the two groups of elastic brackets 201.

[0038] The limiting assembly 30 includes two groups of limiting brackets 301 symmetrically and slidably installed inside the supporting base plate 101, and an adjusting member 302 for controlling the reverse movement of the two groups of limiting brackets 301 is provided at the bottom of the supporting base plate 101. The two groups of limiting brackets 301 are set outside the two groups of guide rollers 202. The dividing assembly 40 includes a movable frame 401 slidably installed on the two groups of round rods 103, and a telescopic dividing member 402 is installed in the middle of the movable frame 401. Two groups of fasteners 403 that slide following the displacement of the telescopic dividing member 402 are symmetrically installed inside the movable frame 401. The opposite sides of the top ends of the two groups of limiting brackets 301 are provided with a card slot 12 for accommodating the movable frame 401, and both sides of the card slot 12 are connected with positioning holes 13 matching the fasteners 403.

[0039] When the device is in use, the ground protection film divider is assembled to the corresponding ground protection film laying device, and the height of the ground protection film winding roller is higher than the mounting bracket 10. The ground protection film to be laid passes between the two sets of guide rollers 202 and the supporting base plate 101 and is laid on the ground. The ground protection film can contact the bottom of the guide roller 202 during the sliding laying process. The movement of the guide roller 202 is controlled by the elastic bracket 201, which facilitates the adjustment of the tension of the ground protection film, and is conducive to laying the ground protection film flatly on the ground. The ground protection film slides between the two sets of limit brackets 301, which can prevent the ground protection film from deviating to both sides during laying, further assisting the normal laying of the ground protection film, and the adjustment member 302 is used to control the distance between the two sets of limit brackets 301, so that the device can efficiently adapt to ground protection films of different widths for use.

[0040] When a row of ground protection film is laid and needs to be divided, the staff can press down the elastic bracket 201 to drive the guide roller 202 to move, and the guide roller 202 and the supporting bottom plate 101 can position and fasten the ground protection film. Pressing the telescopic dividing piece 402 can move the dividing structure at its bottom end to contact the ground protection film. At the same time, the telescopic dividing piece 402 drives the snapping piece 403 to move to separate the movable frame 401 and the limiting bracket 301. The telescopic dividing piece 402 is used to drag the movable frame 401 to slide on the round rod 103 left and right. The bottom end of the telescopic dividing piece 402 can quickly divide the taut ground protection film. After the division is completed, the movable frame 401 moves to the inside of the limiting bracket 301 on the other side, and the external force on the telescopic dividing piece 402 is canceled. The snapping piece 403 is driven to move through its reset, and the snapping piece 403 is embedded in the inside of the positioning hole 13, so that the movable frame 401 is quickly positioned while the dividing structure is retracted to its inside for protection. The ground protection film divider can also be assembled to the film winding device for use according to actual conditions.

[0041] In one embodiment, see Figure 1 to Figure 3 and Figure 6Specifically, the elastic bracket 201 includes multiple groups of sliding rods 2011 installed in the support frame 102 for sliding up and down, and the tops of the multiple groups of sliding rods 2011 are welded with movable plates 2012 rotatably connected to the guide rollers 202, and the bottoms of the multiple groups of sliding rods 2011 are fixedly installed with the same baffle 2013, and multiple groups of first springs 2014 sleeved on the outside of the sliding rods 2011 are installed between the baffle 2013 and the support frame 102. The rotatable guide roller 202 facilitates the auxiliary transportation of the ground protection film. When the guide roller 202 is pulled by external force, it can drive the movable plates 2012 at both ends to move up and down. The movable plate 2012 drives the baffle 2013 to move up and down through the sliding rod 2011, and the baffle 2013 drives the first spring 2014 to expand and contract. The first spring 2014 is convenient for adjusting the tension of the ground protection film in contact with the guide roller 202, and it is convenient to press down the movable plate 2012 to drive the guide roller 202 to move to contact with the support bottom plate 101.

[0042] Furthermore, the same pressing rod 14 is fixedly installed at the top center of the two groups of movable plates 2012. The pressing rod 14 slides through the top of the two groups of support frames 102, which is convenient for the staff to press down the elastic brackets 201 on both sides to move, thereby improving the convenience of operation. Two groups of grooves 15 are opened on the top of the support base plate 101 and are located directly below the guide rollers 202. The bottom surface of the grooves 15 is in an arc shape corresponding to the outer ring size of the guide rollers 202. The pressed guide rollers 202 move into the grooves 15, and the guide rollers 202 on both sides can press the ground protection film to the top of the support base plate 101, so that the tight ground protection film can be quickly and evenly split inside the splitting groove 11 using the splitting structure.

[0043] In one embodiment, see Figure 1 to Figure 3 and Figure 5 Specifically, the limiting bracket 301 includes a U-shaped frame 3011 slidably mounted on the supporting base plate 101 and two groups of round rods 103, and the two bottom ends of the U-shaped frame 3011 are welded with columns 3012 rotatably connected to the adjusting member 302, and the card slot 12 is opened at the top of the U-shaped frame 3011. Two groups of slide grooves 16 for the U-shaped frame 3011 to slide are opened inside the supporting base plate 101, and the inside of the slide groove 16 is welded with an auxiliary rod 3013 that slides through the U-shaped frame 3011. The ground protection film slides between the two groups of U-shaped frames 3011 to prevent the film from deviating to both sides. The auxiliary rod 3013 facilitates improving the stability of the movement of the U-shaped frame 3011, and the card slot 12 is used to position the splitting component 40 to prevent the splitting component 40 from sliding around when the device is running.

[0044] Correspondingly, the adjusting member 302 includes a fixed frame 3021 welded under the supporting base plate 101, a set of adjusting screws 3022 and two sets of limiting rods 3023 are rotatably installed inside the fixed frame 3021, two sets of push-pull rods 3024 that can move in opposite directions are threadedly connected to the adjusting screws 3022, the two sets of limiting rods 3023 slide through the push-pull rods 3024, the push-pull rods 3024 are connected to the column 3012 through the first connecting rod 3025 that is rotatably installed, the operator rotates the adjusting screw 3022 to drive the two sets of push-pull rods 3024 to move synchronously in relative or opposite directions, and the round rod 103 provided limits the specific moving direction of the column 3012 and the U-shaped frame 3011, and the two sets of push-pull rods 3024 can move synchronously in opposite directions. The pull rod 3024 synchronously drives the first connecting rod 3025 connected to it to move, so that the two groups of first connecting rods 3025 on the same side pull the connected columns 3012 and U-shaped frames 3011 to move left and right. Adjusting the distance between the two groups of U-shaped frames 3011 facilitates the device to efficiently adapt to bottom protective films of different widths for use. Among them, two groups of assembly plates 17 are welded on one side of the fixed frame 3021, and multiple groups of mounting holes 18 are provided inside the two groups of assembly plates 17, which facilitates the assembly of the device to the ground protective film laying device or the winding device, etc., and the adjusting screw 3022 extends to one end between the two groups of assembly plates 17 and is equipped with a turntable 19, which facilitates the staff to flexibly control the rotation of the adjusting screw 3022.

[0045] Based on the above embodiments, see Figure 1 to Figure 3 and Figure 7-8 Specifically, the movable frame 401 includes a rectangular frame 4011 installed in the card slot 12, and both sides of the rectangular frame 4011 are connected to a connecting frame 4012 slidably mounted on the round rod 103, and the bottom of the rectangular frame 4011 is connected to a protective frame 4013 mounted on the outside of the telescopic dividing piece 402. The components can be directly welded or detachably connected by bolts and other fasteners. The part of the rectangular frame 4011 protruding from the connecting frame 4012 is conveniently embedded in the card slot 12 of the U-shaped frame 3011 for positioning. When the telescopic dividing piece 402 is fixed, its tip part is retracted to the inside of the protective frame 4013, which can prevent the tip part from accidentally damaging the laid film, and at the same time prevent gravel and other objects from damaging the tip part of the dividing structure, thereby improving the service life of the dividing component.

[0046] Correspondingly, the telescopic dividing member 402 includes a vertical rod 4021 slidably mounted in the middle of the rectangular frame 4011, a mounting plate 4022 is welded to the bottom end of the vertical rod 4021, a partition knife 4023 is mounted on the mounting plate 4022 by bolts, a push-pull plate 4024 is welded to the top end of the vertical rod 4021, a second spring 4025 sleeved on the outside of the vertical rod 4021 is installed between the push-pull plate 4024 and the bottom plate of the rectangular frame 4011, and the mounting plate 4022 is welded to the bottom end of the vertical rod 4021. Both sides are connected to the fastener 403 through a hinged second connecting rod 4026. The push-pull plate 4024 is pressed down to drive the vertical rod 4021, the mounting plate 4022 and the dividing knife 4023 to move downward. The push-pull plate 4024 also drives the second spring 4025 to be compressed. After the dividing knife 4023 moves to the corresponding height, the push-pull plate 4024 is dragged in the horizontal direction to drive the movable frame 401 and its internal structure to translate. The translated dividing knife 4023 facilitates the rapid segmentation of the ground protective film.

[0047] Among them, the fastener 403 includes a connecting plate 4031 slidably installed inside the rectangular frame 4011, one side of the connecting plate 4031 is hinged to the top of the second connecting rod 4026, and the other side of the connecting plate 4031 is symmetrically welded with two groups of clamping rods 4032 that slide through the side plates of the rectangular frame 4011, and the clamping rods 4032 match the size of the positioning holes 13. Two groups of cross bars 4033 that slide through the connecting plate 4031 are welded inside the rectangular frame 4011. The movable mounting plate 4022 can drive the connecting plate 4031 and the clamping rod 4032 to move through the second connecting rod 4026. The clamping rod 4032 moves to the outside of the positioning hole 13, which can realize the rapid separation of the movable frame 401 and the limiting bracket 301. After the movable frame 401 moves to the other side, the second spring 4025 is reset to enable the clamping rod 4032 to be embedded in the corresponding positioning hole 13, which is convenient for realizing the rapid fixation of the movable frame 401 and the rapid storage of the separating knife 4023.
