Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and particularly to an automatic laying and wiring device for communication cables. Background Art

[0002] In order to maintain the transfer and connection of efficient communication information, a large number of communication cables need to be laid. Generally, conventional communication cables are laid in a buried manner. First, a cable trench is dug, then the communication cable is laid into the cable trench, and finally the cable trench is buried to complete the laying and wiring of the communication cable.

[0003] According to a disclosed automatic laying and wiring device for communication cables (Publication No.: CN209434779U), in the above application, the cutting teeth reciprocate up and down under the drive of the driving device to cut the trench for laying the communication cable, and the communication cable is laid at the bottom of the trench through the guidance of the wiring cylinder. Then, the soil cut by the cutting teeth is filled into the trench where the communication cable is laid through the trench burying device to realize the automatic burying of the copper cable, thus completing the automatic laying of the communication cable from the ground to underground.

[0004] However, in the actual use process of the above device, since the laying of the cable is a continuous process, the communication cable in the trench lacks a sufficient positioning and pressing structure, and only a roller is used to guide and flatten it at the bottom of the trench, resulting in a certain time difference between the wiring and the subsequent soil covering operation. This may cause the cable to shift in position at the bottom of the trench, thereby affecting the normal laying effect of the communication cable. In view of this, we have proposed an automatic laying and wiring device for communication cables. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic laying and wiring device for communication cables to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An automatic laying and wiring device for communication cables, including a laying roller and a serrated plate. The side wall of the serrated plate is movably installed with a laying roller through a mounting frame. A communication cable is wound around the arc-shaped outer wall of the laying roller. The bottom side wall of the serrated plate is fixedly connected with a guiding sleeve. A large guiding wheel is rotatably installed on the inner surface of the guiding sleeve. A wire laying assembly is arranged inside the guiding sleeve to achieve preliminary positioning of the communication cable in the trench during laying.

[0007] Preferably, the wire laying assembly includes a V-shaped seat. A rectangular groove is formed at the top of the guiding sleeve near one end of the sawtooth plate. The inner wall of the guiding sleeve is fixedly provided with a V-shaped seat. A small guiding wheel is rotatably installed on the inner wall of the V-shaped seat away from the sawtooth plate. A rotating rod is rotatably installed on the inner wall of the guiding sleeve. The rotating rod penetrates through the laying wheel, and the laying wheel is fixedly connected to the rotating rod. An arc-shaped groove is formed on the arc-shaped outer wall of the laying wheel. Positioning grooves are formed on the inner walls on the left and right sides of the arc-shaped groove. A round rod is rotatably installed on the inner wall of the positioning groove. The round rod penetrates through an arc-shaped rod, and the arc-shaped rod is fixedly connected to the round rod. A scroll spring is sleeved on the arc-shaped outer wall of the round rod.

[0008] Preferably, the V-shaped seat is arranged at the rectangular groove formed at the top of the guiding sleeve. One end of the V-shaped seat close to the sawtooth plate is closed, and the bottom of this closed position is arc-shaped to reduce the resistance of the V-shaped seat to the grooved ground. The V-shaped seat is integrally V-shaped, and one end away from the sawtooth plate is open, so as to facilitate the downward conduction of the communication cable by the large guiding wheel and the small guiding wheel, and finally make it fit the groove opened on the ground.

[0009] Preferably, the number of the positioning grooves is two groups, and the two groups of positioning grooves are symmetrically arranged on the left and right sides of the laying wheel with the vertical central axis of the laying wheel as the symmetry axis. The number of each group of positioning grooves is several, and the several positioning grooves are evenly distributed in a circumferential array on the outer surface of the arc-shaped groove, so that the positioning grooves on both sides of the arc-shaped groove and their corresponding arc-shaped rods can better position and guide the communication cable.

[0010] Preferably, the soil covering assembly includes a first pulley. The rotating rod penetrates through and is fixedly connected to the first pulley. The first pulley is in transmission connection with a second pulley through a transmission belt. The second pulley is coaxially and fixedly installed with a soil covering wheel.

The straight rod penetrates through a transmission plate, and the transmission plate is fixedly connected to the straight rod. A first coil spring is sleeved on the arc-shaped outer wall of the straight rod. A soil covering plate is hinged to the top of the transmission plate. A soil gathering assembly for centering and gathering the floating soil at the bottom of the groove is arranged inside the soil covering plate.

[0011] Preferably, the stop rod is horizontally arranged to better block and limit the transmission plate during rotation, so that it deflects with the straight rod as the rotation center.

[0012] Preferably, the soil gathering assembly includes a transmission rod. One end of the transmission plate away from the straight rod penetrates and fixedly installs a transmission rod. The end of the transmission rod is rotatably connected to the soil covering plate. A second coil spring is sleeved on the arc-shaped outer wall of the transmission rod. A V-shaped groove is formed in the side wall of the soil covering plate. An articulated groove adapted to the width of the top end of the transmission plate is formed at the center of the bottom of the soil covering plate. A blocking block is arranged at the bottom end of the articulated groove. And a blocking strip corresponding to the blocking block is arranged on the side wall of the top end of the transmission plate, so that the soil covering plate can only deflect a certain distance in the clockwise direction under the influence of the elastic force of the second coil spring, thereby facilitating the soil covering plate to better gather and compact the floating soil at the bottom of the trench when patting or sliding the trench.

[0013] Preferably, a soil scraping assembly is arranged at one end of the transmission plate away from the straight rod. The soil scraping assembly includes a hinge seat. One end of the transmission plate away from the straight rod is hinged to the hinge seat. A swinging groove is formed on the upper surface of the hinge seat. A transmission column is rotatably installed on the inner wall of the swinging groove. The transmission column penetrates through a soil scraping plate, and the soil scraping plate is fixedly connected to the transmission column. A third coil spring is sleeved on the arc-shaped outer wall of the transmission column. The number of the swinging grooves and the soil scraping plates is two groups. The two groups of swinging grooves and the soil scraping plates are symmetrically arranged with the vertical central axis of the hinge seat as the axis of symmetry. At the same time, the two soil scraping plates are arranged in an "eight" shape, so that the soil scraping assembly can better scrape the floating soil at the bottom of the trench towards the communication cable at the center when moving along with the transmission plate.

[0014] Preferably, a guiding mechanism for ensuring the stability of the cable during laying and guiding is arranged on the arc-shaped outer surface of the laying wheel. The guiding mechanism includes a connecting rod. The connecting rod is rotatably installed on the inner wall of the positioning groove.

One end of the vertical rod away from the arc-shaped member penetrates through and fixedly installs a rotating rod. A fifth coil spring is sleeved on the arc-shaped outer wall of the rotating rod. The end of the rotating rod is rotatably connected to a blocking belt. A contact roller is rotatably installed on the top inner wall of the blocking belt. An arc-shaped plate is fixedly installed on the top outer wall of the blocking belt.

[0015] Preferably, the number of the contact rollers is multiple groups, and the multiple groups of contact rollers are linearly arranged in the notch formed at the center of the blocking belt to prevent the blocking belt from getting stuck when contacting the cable. The arc-shaped plate is inclined away from the center of the laying wheel, and multiple convex ribs are arranged on the arc-shaped upper surface of the arc-shaped plate to improve the driving effect of the arc-shaped plate on the soil covering the ground.

[0016] Compared with the prior art, the present invention provides an automatic laying and wiring device for communication cables, which has the following beneficial effects:

[0017] 1. For the automatic laying and wiring device for communication cables, by setting a cable laying component, when the laying wheel contacts the surface of the communication cable, the communication cable will exert a squeezing effect on the bottom end of the arc-shaped rod through squeezing in the arc-shaped groove. Eventually, when the laying wheel rotates, it drives the round rod and the arc-shaped rod to deflect, so as to hold the communication cable tightly at this place. After being pressed into the V-shaped small wire groove opened at the bottom of the ground trench, the communication cable is gradually released as the laying wheel rotates. During this process, the guiding and pressing positioning of the communication cable laying are realized, avoiding the situation of deviation or skew after laying between the communication cable and the ground trench, and thus affecting the laying effect of the communication cable and the protection effect of the trench on it after laying.

[0018] 2. For the automatic laying and wiring device for communication cables, by setting a guiding mechanism, when the cable finally detaches from the laying wheel and adheres to the ground as the laying wheel rotates, under the elastic force of the third torsion spring, the arc-shaped part will rotate in the reverse direction. Eventually, the cable will push the blocking rod outward and then adhere to the ground. During this process, the blocking rod deflects outward with the rotating rod as the rotation center until the cable no longer pushes the blocking rod. Then, under the influence of the elastic force of the fourth torsion spring, the blocking rod will drive the arc-shaped plate to deflect towards the center side of the laying wheel, and cooperate with the arc-shaped plate to drive the ground covering soil, so as to initially cover the laid cable with the covering soil, ensuring the laying stability and laying effect of the cable.

[0019] 3. For the automatic laying and wiring device for communication cables, by setting a soil covering component, as the soil covering wheel continues to rotate until the transmission plate moves to a position where the blocking rod can no longer block it, through the release of the elastic force of the first torsion spring, the straight rod will drive the transmission plate to quickly rotate counterclockwise, so as to cooperate with the soil covering plate movably arranged at the top of the transmission plate to compact and pat the communication cable at the bottom of the trench, making it tightly fit at the bottom of the trench and avoiding the situation of deviation, ensuring the stability during the laying of the communication cable.

[0020] 4. For the automatic laying and wiring device for communication cables, by setting a soil gathering component, as the soil covering wheel rotates, when the transmission plate is driven by the elastic force of the first torsion spring to drive the soil covering plate to pat the floating soil in the ground laying trench, with the setting of the V-shaped groove, the floating soil on both sides of the communication cable in the V-shaped small wire groove opened at the bottom of the ground trench will gather towards the surface and upper part of the communication cable, so as to further realize the positioning of the communication cable and prevent the situation of deviation.

[0021] 5. The automatic laying and routing device for communication cables is provided with a soil scraping component, so that the two soil scraping plates arranged in a "V" shape can better achieve centering scraping when contacting the floating soil at the bottom of the trench, thereby completely covering the communication cables laid at the bottom of the trench, ensuring the stable state during the laying of the communication cables, and at the same time facilitating the subsequent backfilling of the trench without affecting the straightness of the communication cables.

Detailed implementation manners

[0035] Embodiment

[0036] As Figures 1 - 6 shown, the present invention provides a technical solution: an automatic laying and wiring device for communication cables, including a laying roller 1 and a serrated plate 2. The side wall of the serrated plate 2 is movably installed with a laying roller 1 through a mounting frame. A communication cable is wound around the arc-shaped outer wall of the laying roller 1. The bottom side wall of the serrated plate 2 is fixedly connected with a guiding sleeve 3. A large guiding wheel 4 is rotatably installed on the inner surface of the guiding sleeve 3. Inside the guiding sleeve 3, there is a wire laying assembly 5 that can achieve preliminary positioning of the communication cable in the trench during laying. The wire laying assembly 5 includes a V-shaped seat 51, a small guiding wheel 52, a rotating rod 53, a laying wheel 54, a positioning groove 55, a round rod 56, an arc-shaped rod 57, and a volute spring 58.

[0037] In an embodiment of the present invention, a rectangular groove is opened at the top of one end of the guiding sleeve 3 close to the serrated plate 2. A V-shaped seat 51 is fixedly installed on the inner wall of the guiding sleeve 3. A small guiding wheel 52 is rotatably installed on the inner wall of the V-shaped seat 51 away from the serrated plate 2. A rotating rod 53 is rotatably installed on the inner wall of the guiding sleeve 3. The rotating rod 53 penetrates through the laying wheel 54, and the laying wheel 54 is fixedly connected with the rotating rod 53. An arc-shaped groove is opened on the arc-shaped outer wall of the laying wheel 54. Positioning grooves 55 are opened on the left and right inner side walls of the arc-shaped groove. A round rod 56 is rotatably installed on the inner wall of the positioning groove 55. The round rod 56 penetrates through an arc-shaped rod 57, and the arc-shaped rod 57 is fixedly connected with the round rod 56. A volute spring 58 is sleeved on the arc-shaped outer wall of the round rod 56.

[0038] Further, the side of the serrated plate 2 with serrations is arranged on the outer wall of the side far from the guiding sleeve 3, and the top end of the serrated plate 2 is detachably connected to an external traction device, so that the whole device can be installed with an external traction trolley, thus saving manpower to continuously complete the laying work of communication cables in the already dug trench. At the same time, the guiding sleeve 3 is arranged in an inverted U shape, so that there is enough space inside the guiding sleeve 3 to arrange the cable laying assembly 5, and it can effectively cooperate with the rectangular groove opened on the top outer wall of the guiding sleeve 3 to guide and lay the communication cables. Specifically, the cable laying assembly 5 is arranged at the vertical central axis of the guiding sleeve 3, so that the device can center the communication cables and ensure the posture and stability during the laying of the communication cables. In addition, the V-shaped seat 51 is arranged at the rectangular groove opened at the top of the guiding sleeve 3, and one end of the V-shaped seat 51 close to the serrated plate 2 is closed, and the bottom of this closed position is arranged in an arc shape to reduce the resistance of the V-shaped seat 51 to the trench ground, and a V-shaped small wire groove can be better opened at the bottom of the trench through the shape of the V-shaped seat 51 to facilitate the subsequent laying of communication cables. Specifically, the V-shaped seat 51 is integrally arranged in a V shape, and its end far from the serrated plate 2 is arranged in an open shape, so as to facilitate the downward conduction of the communication cables by the large guiding wheel 4 and the small guiding wheel 52, and finally make it fit the trench opened on the ground.

[0039] In addition, the laying wheel 54 is arranged at one end of the V-shaped seat 51 away from the sawtooth plate 2, and the laying wheel 54 is arranged at the vertical central axis of the guiding sleeve 3, so that the communication cable passing through the large guiding wheel 4 and the small guiding wheel 52 is finally driven by the laying wheel 54 and pressed at the center of the ground groove, ensuring the straightness of the laying of the communication cable and improving the laying effect of the communication cable. At the same time, the number of the positioning grooves 55 is set to two groups, and the two groups of positioning grooves 55 are symmetrically arranged on the left and right sides of the laying wheel 54 with the vertical central axis of the laying wheel 54 as the axis of symmetry. Specifically, the number of each group of positioning grooves 55 is set to several, and the several positioning grooves 55 are evenly distributed in a circumferential array on the outer surface of the arc groove, so that the positioning grooves 55 on both sides of the arc groove and their corresponding arc rods 57 can better position and guide the communication cable, ensuring its stability when laid at the bottom of the groove. Further, circular holes with a diameter larger than the outer diameter of the scroll spring 58 are opened on the inner walls on the left and right sides of the positioning groove 55, and the two ends of the scroll spring 58 are respectively fixedly connected to the bottom inner wall of the circular hole and the arc outer wall of the round rod 56, so that the round rod 56 always has a tendency to rotate in the reverse direction to reset when rotating with the arc rod 57. Specifically, in the initial state, the bottom end of the arc rod 57 is inclined and arranged inside the arc groove, and the upper surface of the bottom end of the arc rod 57 exceeds the top of the positioning groove 55, so that when the laying wheel 54 contacts the surface of the communication cable, the communication cable will produce a squeezing effect on the bottom end of the arc rod 57 through squeezing in the arc groove, and finally drive the round rod 56 and the arc rod 57 to deflect when driving the laying wheel 54 to rotate, so as to hold the communication cable tightly at this place, and after being pressed into the V-shaped small wire groove opened at the bottom of the ground groove, gradually loosen the communication cable through the rotation of the laying wheel 54. During this process, the guiding and pressing positioning of the communication cable during laying are realized, avoiding the situation of deviation or skew after laying between the communication cable and the ground groove, and further affecting the laying effect of the communication cable and the protection effect of the groove on it after laying.

[0040] In an embodiment of the present invention, a soil covering component 6 for covering and tightly patting the laid communication cable is arranged inside the guiding sleeve 3. The soil covering component 6 includes a first belt pulley 61. The rotating rod 53 penetrates through the first belt pulley 61, and the first belt pulley 61 is fixedly connected to the rotating rod 53. The first belt pulley 61 is in transmission connection with a second belt pulley 63 through a transmission belt 62. The second belt pulley 63 is coaxially and fixedly installed with a soil covering wheel 64. A stop rod 65 is fixedly installed on the inner wall of the guiding sleeve 3. A deflection groove is opened on the arc outer wall of the soil covering wheel 64. A straight rod 66 is rotatably installed on the inner wall of the deflection groove. The straight rod 66 penetrates through a transmission plate 67, and the transmission plate 67 is fixedly connected to the straight rod 66. A first coil spring 68 is sleeved on the arc outer wall of the straight rod 66. The top of the transmission plate 67 is hinged with a soil covering plate 69.

[0041] Specifically, there are two sets of the first pulley 61, the transmission belt 62 and the second pulley 63, and the two sets of the first pulley 61, the transmission belt 62 and the second pulley 63 are mirror - arranged on the left and right sides of the vertical central axis of the laying wheel 54, so as to make the transmission between the laying wheel 54 and the soil - covering wheel 64 more stable. During the process that the laying wheel 54 contacts the surface of the communication cable in the arc - shaped groove and moves along the ground trench with the whole device, the laying wheel 54 will continuously rotate to provide a power source for the rotation of the soil - covering wheel 64. In addition, the stop rod 65 is arranged at the position between the soil - covering wheel 64 and the laying wheel 54, and the stop rod 65 is horizontally arranged to better block and limit the transmission plate 67 during the rotation process, so that it deflects with the straight rod 66 as the rotation center. Further, there are multiple sets of the deflection grooves, the straight rods 66, the transmission plates 67 and the soil - covering plates 69, and the multiple sets of the deflection grooves, the straight rods 66, the transmission plates 67 and the soil - covering plates 69 are evenly distributed in a circular array on the arc - shaped outer wall of the soil - covering wheel 64. At the same time, a baffle is arranged on the inner wall of the deflection groove, and under the elastic force of the first torsion spring 68, the straight rod 66 always has a tendency to drive the transmission plate 67 to deflect towards the laying wheel 54 side, so that in the initial state, the straight rod 66 drives the transmission plate 67 to deflect until it is in contact with the surface of the baffle. Then, during the rotation of the soil - covering wheel 64, due to the blocking effect of the stop rod 65 on the movement track of the transmission plate 67, when the transmission plate 67 contacts the stop rod 65, it will rotate on the inner wall of the deflection groove with the straight rod 66 as the rotation center and continuously generate a compressive force on the first torsion spring 68. As the soil - covering wheel 64 continues to rotate, until the transmission plate 67 moves to a position where the stop rod 65 can no longer block it, through the release of the elastic force of the first torsion spring 68, the straight rod 66 will drive the transmission plate 67 to quickly rotate counter - clockwise, so as to cooperate with the soil - covering plate 69 movably arranged at the top of the transmission plate 67 to compact and pat the communication cable at the bottom of the trench, making it closely fit to the bottom of the trench and preventing it from shifting, thus ensuring the stability during the laying of the communication cable.

[0042] Further, a soil gathering component 7 for centering and gathering the floating soil at the bottom of the trench is arranged inside the soil covering plate 69. The soil gathering component 7 includes a transmission rod 71. One end of the transmission plate 67 far away from the straight rod 66 penetrates and is fixedly installed with the transmission rod 71. The end of the transmission rod 71 is rotatably connected to the soil covering plate 69. A second coil spring 72 is sleeved on the arc-shaped outer wall of the transmission rod 71. A V-shaped groove 73 is opened on the side wall of the soil covering plate 69. Specifically, an articulated groove adapted to the width of the top end of the transmission plate 67 is opened at the center of the bottom of the soil covering plate 69 to facilitate the installation of the transmission rod 71. Circular holes with a diameter larger than the outer diameter of the second coil spring 72 are opened on the inner walls at both ends of the articulated groove. At the same time, both ends of the second coil spring 72 are respectively fixedly connected to the arc-shaped outer wall of the transmission rod 71 and the inner wall of the bottom end of the circular hole. Therefore, due to the elastic force of the second coil spring 72, the transmission rod 71 always has a movement tendency of reverse rotation to achieve reset. Specifically, a blocking block is arranged at the bottom end of the articulated groove, and a blocking strip corresponding to the blocking block is arranged on the side wall of the top end of the transmission plate 67, so that the soil covering plate 69 can only deflect a certain distance in the clockwise direction under the influence of the elastic force of the second coil spring 72, thereby facilitating the soil covering plate 69 to better gather and press the floating soil at the bottom of the trench when patting or sliding on the trench, improving the use effect of the soil covering plate 69, and ensuring the stability during the laying of communication cables. Embodiment

[0043] On the basis of Embodiment 1, please specifically refer to the attached Figures 7 - 8 In this embodiment, a soil scraping component 8 is arranged at one end of the transmission plate 67 far away from the straight rod 66. The soil scraping component 8 includes a hinge seat 81. One end of the transmission plate 67 far away from the straight rod 66 is hinged with the hinge seat 81. A swing groove 82 is opened on the upper surface of the hinge seat 81. A transmission column 83 is rotatably installed on the inner wall of the swing groove 82. A soil scraping plate 84 penetrates through the transmission column 83, and the soil scraping plate 84 is fixedly connected to the transmission column 83. A third coil spring 85 is sleeved on the arc-shaped outer wall of the transmission column 83.

[0044] In the second embodiment of the present invention, there are two sets of swing grooves 82 and soil scraping plates 84. The two sets of swing grooves 82 and soil scraping plates 84 are symmetrically arranged with the vertical central axis of the hinge seat 81 as the axis of symmetry. Thus, when the soil scraping assembly 8 moves along with the driving plate 67 to scrape the floating soil at the bottom of the trench, it can better scrape the floating soil towards the communication cable at the center to cover the surface of the communication cable. At the same time, both ends of the third torsion spring 85 are respectively fixedly connected to the inner wall of the swing groove 82 and the arc-shaped outer wall of the transmission column 83. And the same hinge groove and corresponding blocking blocks as those at the bottom of the soil covering plate 69 are provided on the inner wall of the bottom of the hinge seat 81, so that the hinge seat 81 can only deflect a certain distance in the clockwise direction under the influence of the elastic force of the second torsion spring 72, which is convenient for the soil scraping assembly 8 to better gather the floating soil at the bottom of the trench when patting the trench. And the two soil scraping plates 84 are arranged in a "V" shape, so that the soil scraping plates 84 can better achieve centering scraping when contacting the floating soil at the bottom of the trench, so as to completely cover the communication cable laid at the bottom of the trench, ensure the stable state during the laying of the communication cable, and at the same time facilitate the subsequent backfilling of the trench without affecting the straightness of the communication cable.

At the same time, an activity cavity is formed inside the arc-shaped member 92, and the sleeve rod 94 and the connecting spring 95 are both arranged inside the activity cavity. A square block is slidably mounted on the inner wall of the activity cavity, and the square block is fixedly connected to the arc-shaped contact block 96. A wide groove is formed on the top inner wall of the arc-shaped member 92, and the width of the wide groove is adapted to the width of the connecting part of the square block and the arc-shaped contact block 96, so that when the arc-shaped contact block 96 contacts the cable, the arc-shaped contact block 96 can move on the surface of the arc-shaped member 92 to avoid rigid contact with the cable surface, thereby affecting the laying safety of the cable. Further, a notch with a width adapted to the width of the vertical rod 97 is formed at the center of the retaining belt 99 to facilitate the rotation of the retaining belt 99 around the rotating rod 98 as the rotation center, and at the same time avoid jamming between the retaining belt 99 and the vertical rod 97.

[0047] Further, a plurality of contact rollers 911 are provided, and the plurality of contact rollers 911 are linearly arranged in the notch formed at the center of the retaining belt 99 to avoid jamming when the retaining belt 99 contacts the cable. In addition, the arc-shaped plate 912 is inclined away from the center of the laying wheel 54, and a plurality of convex ribs are arranged on the arc-shaped upper surface of the arc-shaped plate 912 to improve the driving effect of the arc-shaped plate 912 on the ground covering soil. Specifically, when the laying wheel 54 contacts the cable, the cable first passes through the surface of the retaining belt 99, its outer wall contacts the contact rollers 911 and finally approaches the arc-shaped member 92. As the laying wheel 54 continues to rotate, the cable is finally pressed against the surface of the arc-shaped member 92. By providing the connecting spring 95 and the arc-shaped contact block 96, the cable is protected. At the same time, the extrusion of the cable on the arc-shaped member 92 will also cause the arc-shaped member 92 to deflect towards the center of the laying wheel 54 around the connecting rod 91 as the rotation center. The retaining belt 99 is provided to provide preliminary protection for the cable. Then, when the cable moves close to the ground, since the cable disengages from the laying wheel 54, under the elastic force of the torsion spring four 93, the arc-shaped member 92 will rotate in the reverse direction. Finally, the cable will push the retaining belt 99 outwards and stick to the ground. During this process, the retaining belt 99 deflects outwards around the rotating rod 98 as the rotation center until the cable no longer pushes the retaining belt 99. Then, under the elastic force of the torsion spring five 910, the retaining belt 99 will drive the arc-shaped plate 912 to deflect towards the center side of the laying wheel 54, and cooperate with the driving effect of the arc-shaped plate 912 on the ground covering soil to initially cover the covering soil on the laid cable and ensure the laying stability and laying effect of the cable.

[0048] In the present invention, during use, the serrated plate 2 is installed on an external traction device, and the device is centered and aligned with the laying groove opened on the ground. Then, one end of the communication cable wound around the laying roller 1 passes through the bottoms of the large guide wheel 4 and the small guide wheel 52, and then closely adheres to the arc-shaped groove on the surface of the laying wheel 54 and finally passes through the bottom of the laying wheel 54, and finally extends out from the right end of the guide sleeve 3. The end thereof is positioned at the bottom of the ground laying groove through a fixing device. At this time, the traction device is started, and it moves continuously along the ground laying groove in cooperation with the serrated plate 2. At this time, since one end of the communication cable is fixed, through the continuous movement of the device, the laying roller 1 rotates continuously and thus continuously releases the communication cable, and the communication cable is restricted to the center of the ground laying groove through the cable laying assembly 5, and the communication cable is fixed by the soil covering assembly 6 and the soil gathering assembly 7, completing the preliminary laying and positioning of the communication cable and the soil covering protection, ensuring that the communication cable will not be damaged and will not shift during the subsequent backfilling of the ground groove, affecting the overall laying effect of the communication cable.

[0049] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
