A stabilizing frame 13 is provided on the lower side of the main bracket 11. One end of the connecting rod 25 is connected to the connecting plate 23. The other end of the connecting rod 25 passes through the stabilizing frame 13 and the main bracket 11 in sequence and is connected to the first limit plate 26. The electric push rod 27 is provided on the main bracket 11 and is sleeved on the outside of the connecting rod 25 for adjusting the connection rod 25 to rise or fall.

[0039] The first limit plate 26 is pushed to move by the electric push rod 27, so that the first limit plate 26 drives the distribution member 21 to move through the connecting rod 25, so that the position of the distribution member 21 can be adjusted according to the depth of different cable trenches, so that the bottom of the distribution member 21 is located in the center layer of the sand layer. In order to enhance the structural strength of the distribution member 21 and prevent the distribution member 21 from deformation, a reinforcing rib 28 is integrally formed on one side of the distribution member 21.

[0040] In order to enhance the stability of the distribution member 21 during movement, a stabilizing frame 13 is fixedly connected to one side of the main bracket 11, and a connecting rod 25 passes through the stabilizing frame 13.

The cable on the winding roller 31 passes through the straightening wheel 34 and the limit assembly in turn and enters the slot. The winding roller 31 is driven to rotate by the servo motor 32, which is convenient for the winding and unwinding operations of the cable. The speed of the servo motor 32 is adjustable, which is convenient for adjusting the unwinding speed according to the laying requirements of different cables. The cable is guided and straightened by the straightening wheel 34 to prevent the position deviation of the cable during unwinding and causing the laying misalignment.

[0042] The two righting wheels 34 are symmetrically arranged, and a recess is provided in the middle of the righting wheels 34. The cable is placed in the recess between the two righting wheels 34 to ensure that the cable will not deviate during the laying process.

[0043] In this embodiment, the limiting assembly includes a guide rail, a movable plate 36 and a limiting wheel 37. The guide rail is an electric guide rail 35, which is vertically arranged on the fixed frame 33. The movable plate 36 is slidably connected to the electric guide rail 35. The limiting wheel 37 is arranged at the bottom of the movable plate 36. The surface of the limiting wheel 37 is provided with a limiting groove for limiting the deviation of the cable. The limiting wheel 37 is rotatably connected to the movable plate 36, and the movable plate 36 is driven to move by the electric guide rail 35, so that the movable plate 36 drives the limiting wheel 37 to move.

[0044] In this embodiment, the sand filling mechanism 40 includes a toggle assembly, a second mounting frame 42, an insertion rod 46 and a second limiting plate 47. The second mounting frame 42 is provided with a plurality of fixing holes 45 along the vertical direction. The second mounting frame 42 is inserted into the main bracket 11. The top end of the second mounting frame 42 is connected to the second limiting plate 47. The bottom end of the second mounting frame 42 is connected to the toggle assembly. The insertion rod 46 is on the main bracket 11 and inserted into the fixing hole 45 for positioning the insertion rod 46. The toggle assembly is used to fill the sand layer. The second limiting plate 47 limits the second mounting frame 42 to prevent the second mounting frame 42 from being separated from the main bracket 11. Fixing holes 45 are evenly spaced on both sides of the second mounting frame 42. Insertion rods 46 are inserted into the fixing holes 45. By inserting the insertion rods 46 into the fixing holes 45, the use height of the toggle plate 41 is adjusted. The insertion rods 46 are located above the fixing plate 14, so that the toggle plate 41 can jump upward when passing through uneven roads, preventing the toggle plate 41 from getting stuck on the uneven road surface and affecting the laying of cables.

[0045] In this embodiment, the toggle assembly includes a second screw 44 and two symmetrically arranged toggle plates 41, the second screw 44 is provided with two sections of external threads in opposite directions, the two toggle plates are respectively threadedly connected to the corresponding external threads, and the two toggle plates 41 are arranged to form a landfill opening, the front end of the landfill opening is wider than the rear end of the landfill opening, and the front end of the landfill opening is wider than the distribution mechanism 20.

[0046] The working principle of this scheme is as follows: dig the cable trench, remove the debris in the trench, lay a sand cushion layer at the bottom of the trench, and directly lay the sand layer. Lay a half-volume sand layer at the starting section of the cable laying, align the center of the main bracket 11 with the cable trench, wind the cable on the winding roller 31, pass the cable through the straightening wheel 34, and make the cable under the limiting wheel 37 and contact with the limiting wheel 37, fix one end of the cable in the cable trench, start the electric push rod 27, and drive the first limiting plate 26 to move. The first limit plate 26 drives the dividing member 21 to move through the connecting rod 25, so that the dividing member 21 enters the cable trench and contacts the sand layer, so that the bottom surface of the dividing member 21 is located at the center of the sand layer, and the baffles 24 on both sides of the dividing member 21 are in contact with the cable trench, and the electric guide rail 35 is started to drive the movable plate 36 to move downward, so that the limit wheel 37 is located at the center of the sand layer, and the plug rod 46 is pulled out to move the second mounting frame 42 downward, so that the toggle plate 41 contacts the ground, and the second screw rod 44 is rotated, with The toggle plate 41 is moved and the position of the toggle plate 41 is adjusted according to the size of the cable trench so that the toggle plate 41 is located on both sides of the ground part of the cable trench. The first adjusting rod 18 is rotated to drive the first mounting frame 16 to move, so that the pressure wheel 17 contacts the ground, the main bracket 11 is moved and the servo motor 32 is started. The servo motor 32 drives the winding roller 31 to rotate to release the cable. During the movement of the main bracket 11, the dividing member 21 divides the sand layer so that the filled sand layer moves with the dividing member 21. The dividing member 21 guides the upper half of the sand layer to the ground so that it is located on both sides of the cable trench. At the same time, the pressure ball 22 leaves an indentation in the sand layer to provide a laying slot for the cable. After the cable is released, it is laid in the sand layer one by one through the limiting wheel 37, and when the toggle plate 41 passes by, the sand layers on both sides of the cable trench are refilled into the cable trench. The sand filling process is completed immediately after the cable is laid, and the pressure wheel 17 compacts the sand layer when passing through the cable trench after the sand filling process.
