Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and specifically to a direct-buried cable laying device for a wind farm collector line. Background Art

[0002] Nowadays, with the rapid development of social economy, the power and communication industries are also accelerating their development. A wind farm is a place where wind energy is converted into electrical energy, consisting of multiple wind turbines and related supporting facilities. These wind turbines are arranged in a certain layout to form a large-scale power generation system. The electrical energy generated by the wind turbines is collected and transported to a step-up substation, and then the step-up substation transports the electrical energy to the power grid to achieve long-distance transmission and distribution of electrical energy. Cables are used to collect the electrical energy generated by wind turbines into a collector box, generally composed of copper, aluminum, or copper-aluminum hybrid wires, and have good electrical conductivity and insulation properties. In the wind farm collector line, a large number of cables are used. When constructing direct-buried cables, direct-buried cable laying equipment is required.

[0003] Currently, when the existing direct-buried cable laying equipment lays cables, when encountering hard soil, it is inconvenient to pre-treat the soil, resulting in subsequent disadvantages for the cable trench and affecting the overall laying of the cables. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A direct-buried cable laying device for a wind farm collector line includes a frame. A wire combing roller is rotatably installed at the middle of the top of the frame, and a trench digging mechanism is installed at the middle of the interior of the frame;

[0006] A soil drilling mechanism, which is used to pre-treat hard soil, and the soil drilling mechanism is installed at the cable inlet end on the surface of the frame;

[0007] Among them, the soil drilling mechanism includes an open substrate and a hydraulic cylinder. The open substrate is fixedly installed at the cable inlet end on the surface of the frame. The hydraulic cylinder is fixedly installed at the notch on the top of the frame. A driver is fixedly installed at the telescopic end of the hydraulic cylinder. A soil-breaking drill bit is installed at the output end of the bottom of the driver. A guiding square column is fixedly installed at the side of the top of the driver and close to the hydraulic cylinder. A support connecting piece is fixedly installed at the top of the open substrate and close to the guiding square column. The surface of the guiding square column is slidably installed between the support connecting pieces. A cleaning component is installed at the bottom of the open substrate and close to the driver. By rotating the output end of the driver, the soil-breaking drill bit can be driven to rotate, and the hydraulic cylinder is started to work. By extending the telescopic end of the hydraulic cylinder, the driver can be driven to move downward, so that the soil-breaking drill bit moves downward together with the driver. Then, the tip of the soil-breaking drill bit can be used to contact the harder soil. Along with the continuous rotation of the soil-breaking drill bit, the soil can be drilled, and the soil is broken and drilled, so as to pre-treat the soil.

[0008] After the preliminary drilling is completed, the hydraulic cylinder can be used again for work. By contracting the telescopic end of the hydraulic cylinder, the driver can be lifted, so that the soil-breaking drill bit is separated from the soil. Then, by extending and contracting the telescopic end of the hydraulic cylinder, the soil can be continuously drilled and pre-treated.

[0009] The burying mechanism is used to cover the cable with soil. The burying mechanism is installed at one end of the frame far from the open substrate.

[0010] Among them, the burying mechanism includes a connecting frame and a scraper. The connecting frame is fixedly installed at one end of the frame far from the open substrate. The scraper is fixedly installed at the bottom end of the connecting frame. A rolling wheel is rotatably installed at the bent part of the surface of the scraper. A raised block is fixedly connected to the outer circumferential surface of the rolling wheel. A wire pressing component is installed at the top of the scraper and close to the trench opening mechanism. Supported by the connecting frame and driven by the forward movement of the frame, the scraper is driven to move together. Considering that the scraper is V-shaped, the broken soil on both sides of the trench can be gathered and scraped into the trench again, so as to bury the cable. Along with the scraper driving the rolling wheel to roll, and using the raised block to reduce the contact area with the broken soil, the pressure is increased, so that the broken soil can be effectively compacted, which is helpful for cable laying.

[0011] Preferably, there are two hydraulic cylinders, and the two hydraulic cylinders are symmetrically installed along the central axis in the middle of the driver. The tip of the soil-breaking drill bit faces downward.

[0012] When moving downward through the drive, the guiding square column will be driven to move downward together. With the sliding installation between the guiding square column and the supporting connecting piece, the guiding square column can support and guide the drive, so that when the earth-breaking drill cone drills and breaks the land, the overall structure is more stable and not prone to shaking.

[0013] Preferably, the guiding square column is vertically installed. There are two guiding square columns, and the two guiding square columns are symmetrically installed along the central axis in the middle of the drive. The guiding square column passes through the center of the supporting connecting piece.

[0014] Preferably, the cleaning component includes a bracket. The top of the bracket is fixedly connected to the side of the bottom of the opening substrate by bolts. A swing plate is rotatably installed at the bottom end of the bracket. A wire brush is fixedly installed on the surface of the swing plate and close to the drive side. A round rod is fixedly installed in the middle of the top of the swing plate. The top end of the round rod is fixedly connected with a tension spring. As the drive moves upward, the round rod will receive the upward pushing force of the drive. Under the support of the bracket, the swing plate is forced to rotate and adjust the angle, so that the wire brush is driven by the swing plate to move together, and the tension spring is stretched. By using the end of the wire brush to contact the earth-breaking drill cone, as the earth-breaking drill cone rotates, the soil attached to the surface of the earth-breaking drill cone can be removed, reducing the influence of soil adhesion.

[0015] Preferably, the swing plate is inclinedly installed. The wire brushes are evenly distributed on the surface of the swing plate and close to the drive side. The round rod is inclinedly installed.

[0016] As the drive moves downward, the pushing force on the round rod by the drive disappears. Under the elastic pulling force of the tension spring, the round rod drives the swing plate to rotate in the reverse direction for resetting, so that the wire brush moves to the side away from the earth-breaking drill cone, making it possible for the drive and the earth-breaking drill cone to move downward smoothly without obstacles and structural jams.

[0017] Preferably, the scraping plate is V-shaped, and the V-shaped opening of the scraping plate faces the side of the wire pressing component. The raised blocks are evenly distributed on the outer circular surface of the rolling wheel.

[0018] Preferably, the wire pressing component includes a supporting elastic sheet and a guiding sleeve. The bottom end of the supporting elastic sheet is fixedly connected to the reinforcing rib at the top of the scraping plate. The supporting elastic sheet is installed on the side close to the trench opening mechanism. The top end of the supporting elastic sheet is fixedly installed with a frame. A wire pressing wheel is rotatably installed at the bottom of the frame. Right-angle force-bearing rods are fixedly connected to the surfaces on both sides of the frame. The right-angle force-bearing rods are installed inside the frame. The outer circular surface of the right-angle force-bearing rod is slidably installed with the guiding sleeve. As the cable to be laid bypasses the bottom of the wire pressing wheel and is supported by the frame, through the rolling of the wire pressing wheel, the cable can be rolled and pressed, so that the cable is laid in the trench in an orderly manner.

[0019] Preferably, the supporting spring piece is arc-shaped, there are two right-angle force-bearing rods, and the two right-angle force-bearing rods are symmetrically installed along the frame, and the right-angle force-bearing rods pass through the center of the guide sleeve.

[0020] Preferably, the ditching mechanism includes a gantry, the top of the gantry is fixedly connected to the middle of the inside of the frame by screws, the bottom end of the gantry is rotatably mounted with a round roller, the surface of the gantry and a position close to the round roller is fixedly mounted with a servo motor, the output end of the servo motor is fixedly mounted between the round roller through a coupling, the middle of the outer cylindrical surface of the round roller is fixedly connected with a ditching tooth, the top of the inner side surface of the gantry and a position close to the ditching tooth is fixedly connected with a fender, and the surface of the guide sleeve is fixedly connected to the side of the fender surface Then, a crescent block is fixedly installed on the surface of the round roller near the inner side of the gantry, the right-angle force-bearing rod extends to the position of the crescent block at one end away from the frame, and a soil-turning plow is fixedly installed on the surface of the fender near the bottom. The round roller is driven to rotate by the rotation of the output end of the servo motor and the fixed connection of the coupling. The trenching teeth will rotate with the round roller, and the trenching teeth can be used to dig trenches on the land that has been pre-treated by the drilling of the earth-breaking drill cone, and the wheels at the bottom of the frame can be rolled to carry out continuous trenching.

[0021] The broken soil generated during trenching is blocked by the mudguard, which makes it less likely for the broken soil to splash, reducing the harm to personnel caused by the splashing of the broken soil. The mudguard blocks the broken soil, and the broken soil falls down immediately. As the soil-turning plow moves with the mudguard, the broken soil in the trench can be turned to both sides, so the broken soil in the trench can be cleaned, which is helpful for the subsequent laying of direct buried cables.

[0022] Preferably, the crescent blocks are evenly distributed on the surface of the round roller and close to the inner side surface of the gantry, the position of the soil plow corresponds to the position of the trenching teeth, and the round roller is driven to rotate by the output end of the servo motor, and the crescent blocks will rotate with the round roller. The crescent blocks are in contact with the end of the right-angle force rod, so that the right-angle force rod is subjected to a driving force in the direction of the frame, and the right-angle force rod can be used to push the frame, so that the wire pressing wheel moves toward the side close to the scraper, and the supporting spring piece is compressed. As the crescent block is separated from the end of the right-angle force rod, the driving force on the right-angle force rod disappears, and under the elastic force of the supporting spring piece, the frame and the wire pressing wheel move forward together to reset, so that the cable in the groove is flattened by the reciprocating rolling of the wire pressing wheel, and it is not easy to warp.

[0023] The present invention provides a direct buried cable laying device for wind farm collector lines. It has the following beneficial effects:

[0024] 1. For the direct-buried cable laying equipment of the wind farm collector line, by extending the telescopic end of the hydraulic cylinder, the drive can be driven downward, so that the earth-breaking drill cone moves downward with the drive. Then, the tip of the earth-breaking drill cone can be used to contact the relatively hard soil. Along with the continuous rotation of the earth-breaking drill cone, the soil can be drilled, broken, and thus the soil can be pre-treated. When the preliminary drilling is completed, the hydraulic cylinder can be used again. By contracting the telescopic end of the hydraulic cylinder, the drive can be lifted, so that the earth-breaking drill cone is separated from the soil. Then, by extending and contracting the telescopic end of the hydraulic cylinder, the soil can be continuously drilled and pre-treated.

[0025] 2. For the direct-buried cable laying equipment of the wind farm collector line, when the drive moves downward, the guiding square column will be driven to move downward together. Considering the sliding installation between the guiding square column and the supporting connecting piece, the guiding square column can support and guide the drive. As a result, when the earth-breaking drill cone drills and breaks the soil, the overall structure is more stable and less likely to shake.

[0026] 3. For the direct-buried cable laying equipment of the wind farm collector line, as the drive moves upward, the round rod will receive the upward pushing force from the drive. Under the support of the bracket, the swing plate is forced to rotate and adjust the angle. Consequently, the wire brush is driven to move together by the swing plate, and the tension spring is stretched. By using the end of the wire brush to contact the earth-breaking drill cone, along with the rotation of the earth-breaking drill cone, the soil attached to the surface of the earth-breaking drill cone can be removed, reducing the influence of soil adhesion.

[0027] 4. For the direct-buried cable laying equipment of the wind farm collector line, as the drive moves downward, the pushing force on the round rod from the drive disappears. Under the elastic pulling force of the tension spring, the round rod drives the swing plate to rotate in the reverse direction for resetting. As a result, the wire brush moves to the side away from the earth-breaking drill cone, enabling the drive and the earth-breaking drill cone to move downward smoothly, and less likely to encounter obstacles and structural jams.

[0028] 5. For the direct-buried cable laying equipment of the wind farm collector line, by using the rotation of the output end of the servo motor and the fixed connection of the coupling, the round roller is driven to rotate. The trench-digging teeth will rotate with the round roller. Then, the trench-digging teeth can be used to dig a trench in the soil that has been pre-treated by the earth-breaking drill cone. By rolling the wheels at the bottom of the frame, continuous trenching can be carried out.

[0029] 6. For the direct-buried cable laying equipment of the wind farm collector line, the broken soil generated during trenching is blocked by the mud guard, making it less likely for the broken soil to splash. This reduces the harm caused by the splashing broken soil to personnel. Moreover, the mud guard blocks the broken soil, and the broken soil then falls. Along with the soil-turning plow moving with the mud guard, the broken soil in the trench can be turned to both sides, thus cleaning the broken soil in the trench, which helps with the subsequent laying of the direct-buried cable.

[0030] 7. The direct buried cable laying equipment for the wind farm collector line, as the cable to be laid passes around the bottom of the crimping wheel and is supported by the frame, the cable can be rolled by the rolling of the crimping wheel, so that the cable can be laid in the groove in an orderly manner.

[0031] 8. The direct buried cable laying equipment for the wind farm collector line utilizes the crescent block to contact the end of the right-angle force-bearing rod, so that the right-angle force-bearing rod is subjected to a driving force toward the direction of the frame. The right-angle force-bearing rod can then be used to push the frame, causing the pressure wheel to move toward the side close to the scraper, and the supporting spring piece to be compressed. As the crescent block is separated from the end of the right-angle force-bearing rod, the driving force on the right-angle force-bearing rod disappears, and under the elastic force of the supporting spring piece, the frame and the pressure wheel move forward together to reset. In this way, the cable in the groove is flattened by the reciprocating rolling of the pressure wheel, and is not prone to warping.

[0032] 9. The direct buried cable laying equipment for the wind farm collector line uses the frame to move forward, so that the scraper is driven to move together, and the scraper is V-shaped, so the broken soil on both sides of the groove can be gathered and scraped into the groove again, so that the cable can be buried. As the scraper drives the rolling wheel to roll and the raised blocks are used to reduce the contact area with the broken soil, the pressure is increased, which can effectively compact the broken soil and help to lay the cable.

Specific embodiments

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] The first embodiment is as Figures 1 to 5 shown, and the present invention provides a technical solution:

[0045] A direct-buried cable laying device for a wind farm collector line includes a frame 1, a wire combing roller 2 is rotatably installed at the middle of the top of the frame 1, and a trench-opening mechanism 3 is installed at the middle of the inside of the frame 1;

[0046] A soil drilling mechanism 4, which is used for preprocessing hard soil, and the soil drilling mechanism 4 is installed at the cable inlet end on the surface of the frame 1;

[0047] Among them, the soil drilling mechanism 4 includes an open substrate 41 and a hydraulic cylinder 42. The open substrate 41 is fixedly installed at the cable inlet end on the surface of the frame 1, and the hydraulic cylinder 42 is fixedly installed at the notch on the top of the frame 1. A driver 43 is fixedly installed at the telescopic end of the hydraulic cylinder 42. A soil-breaking drill cone 44 is installed at the output end of the bottom of the driver 43. A guiding square column 45 is fixedly installed at the side of the top of the driver 43 and close to the hydraulic cylinder 42. A support connecting piece 46 is fixedly installed at the top of the open substrate 41 and close to the guiding square column 45. The guiding square column 45 is slidably installed between the surface of the guiding square column 45 and the support connecting piece 46. A cleaning component 47 is installed at the bottom of the open substrate 41 and close to the driver 43. The staff turns on the driver 43 to work. Using the driver 43 as the power, through the rotation of the output end of the driver 43, the soil-breaking drill cone 44 can be driven to rotate, and the hydraulic cylinder 42 is turned on to work. Using the elongation of the telescopic end of the hydraulic cylinder 42, the driver 43 can be driven to move downward, so that the soil-breaking drill cone 44 moves downward together with the driver 43. Then, the tip of the soil-breaking drill cone 44 can be used to contact the relatively hard soil. Along with the continuous rotation of the soil-breaking drill cone 44, the soil can be drilled, the soil drilling can be broken, and thus the soil can be pre-treated;

[0048] After the preliminary drilling is completed, the hydraulic cylinder 42 can be used again to work. By contracting the telescopic end of the hydraulic cylinder 42, the driver 43 can be lifted, so that the soil-breaking drill cone 44 is separated from the soil. Then, by elongating and contracting the telescopic end of the hydraulic cylinder 42, the soil can be continuously pre-treated by drilling;

[0049] There are two hydraulic cylinders 42, and the two hydraulic cylinders 42 are symmetrically installed along the central axis in the middle of the driver 43. The tip of the soil-breaking drill cone is downward.

[0050] When the driver 43 moves downward, the guiding square column 45 will be driven to move downward together. Combining the sliding installation between the guiding square column 45 and the support connecting piece 46, the guiding square column 45 supports and guides the driver 43, so that when the soil-breaking drill cone 44 breaks the soil by drilling, the overall structure is more stable.

[0051] The guiding square column 45 is vertically installed. There are two guiding square columns 45, and the two guiding square columns 45 are symmetrically installed along the central axis in the middle of the driver 43. The guiding square column 45 passes through the center of the support connecting piece 46.

[0052] The cleaning component 47 includes a support 471. The top of the support 471 is fixedly connected to the side of the bottom of the opening substrate 41 by bolts. A swing plate 472 is rotatably installed at the bottom end of the support 471. A wire brush 473 is fixedly installed on the surface of the swing plate 472 and on the side close to the driver 43. A round rod 474 is fixedly installed at the middle of the top of the swing plate 472. The top end of the round rod 474 is fixedly connected to a tension spring 475. As the driver 43 moves upward, the round rod 474 will receive an upward pushing force from the driver 43. Under the support of the support 471, the swing plate 472 is forced to rotate and adjust the angle, so that the wire brush 473 is driven by the swing plate 472 to move together, and the tension spring 475 is stretched. By using the end of the wire brush 473 to contact the earth-breaking drill cone 44, as the earth-breaking drill cone 44 rotates, the soil attached to the surface of the earth-breaking drill cone 44 can be removed.

[0053] The swing plate 472 is inclinedly installed. The wire brushes 473 are evenly distributed on the surface of the swing plate 472 and on the side close to the driver 43. The round rod 474 is inclinedly installed. As the driver 43 moves downward, the upward pushing force on the round rod 474 from the driver 43 disappears. Under the elastic pulling force of the tension spring 475, the round rod 474 drives the swing plate 472 to rotate in the reverse direction for resetting, so that the wire brush 473 moves away from the earth-breaking drill cone 44, which can make the driver 43 and the earth-breaking drill cone 44 move downward smoothly without being blocked or jammed.

[0054] Second embodiment. On the basis of the first embodiment, please refer to Figures 1 to 7 as shown in:

[0055] The burying mechanism 5 is used to cover the cable with soil. The burying mechanism 5 is installed at one end of the frame 1 far away from the opening substrate 41;

[0056] Among them, the burying mechanism 5 includes a connecting frame 51 and a scraping plate 52. The connecting frame 51 is fixedly installed at one end of the frame 1 far away from the opening substrate 41. The scraping plate 52 is fixedly installed at the bottom end of the connecting frame 51. A rolling wheel 53 is rotatably installed at the bent part of the surface of the scraping plate 52. A raised block 54 is fixedly connected to the outer circumferential surface of the rolling wheel 53. A wire pressing component 55 is installed at the top of the scraping plate 52 and close to the trench-opening mechanism 3. Under the support of the connecting frame 51 and by using the forward movement of the frame 1, the scraping plate 52 is driven to move together. Considering that the scraping plate 52 is V-shaped, the broken soil on both sides of the trench can be gathered and scraped back into the trench again, so that the cable can be buried. As the scraping plate 52 drives the rolling wheel 53 to roll, and by using the raised block 54 to reduce the contact area with the broken soil, the pressure is increased, so that the broken soil can be effectively compacted.

[0057] The scraper 52 is V-shaped, and the V-shaped opening of the scraper 52 faces one side of the wire pressing assembly 55 . The protrusions 54 are evenly distributed on the outer circumference of the rolling wheel 53 .

[0058] The wire pressing assembly 55 includes a supporting spring piece 551 and a guide sleeve 552. The bottom end of the supporting spring piece 551 is fixedly connected to the reinforcing rib at the top of the scraper 52. The supporting spring piece 551 is installed on the side close to the ditching mechanism 3. The top of the supporting spring piece 551 is fixedly installed with a frame 553. The bottom of the frame 553 is rollingly installed with a wire pressing wheel 554. The surfaces on both sides of the frame 553 are fixedly connected with a right-angle force rod 555. The right-angle force rod 555 is installed inside the frame 1. The outer cylindrical surface of the right-angle force rod 555 is slidably installed between the guide sleeve 552. As the cable to be laid passes around the bottom of the wire pressing wheel 554 and is supported by the frame 553, the cable can be rolled by the rolling of the wire pressing wheel 554, so that the cable is laid in the groove in an orderly manner.

[0059] The supporting spring piece 551 is arc-shaped. There are two right-angle force-bearing rods 555 , and the two right-angle force-bearing rods 555 are symmetrically installed along the frame 553 . The right-angle force-bearing rods 555 pass through the center of the guide sleeve 552 .

[0060] The third embodiment, based on the first and second embodiments, see Figures 1 to 9 As shown:

[0061] The ditching mechanism 3 includes a gantry 31, the top of the gantry 31 is fixedly connected to the middle of the inside of the frame 1 by screws, and a round roller 32 is rotatably installed at the bottom end of the gantry 31. A servo motor 33 is fixedly installed on the surface of the gantry 31 and near the position of the round roller 32. The output end of the servo motor 33 is fixedly installed between the round roller 32 through a coupling. A ditching tooth 34 is fixedly connected to the middle of the outer cylindrical surface of the round roller 32. A fender 35 is fixedly connected to the top of the inner side of the gantry 31 and near the position of the ditching tooth 34. The surface of the guide sleeve 552 is fixedly connected to the side of the surface of the fender 35. The surface of the round roller 32 and near the inner surface of the gantry 31 are fixedly connected. A crescent block 36 is fixedly installed at the side position, and one end of the right-angled force-bearing rod 555 extends away from the frame 553 to the position of the crescent block 36. A soil-turning plow 37 is fixedly installed on the surface of the fender 35 near the bottom position. The staff turns on the servo motor 33 to work, and uses the rotation of the output end of the servo motor 33 and the fixed connection of the coupling to drive the round roller 32 to rotate. The trenching teeth 34 will rotate with the round roller 32, and the trenching teeth 34 can be used to dig trenches on the land that has been drilled and pre-treated by the earth-breaking drill cone 44, and the wheels at the bottom of the frame 1 are used to roll. The equipment moves as a whole, and continuous trenching can be carried out.

[0062] The broken soil generated during trench digging is blocked by the mudguard 35, making it less likely for the broken soil to splash, reducing the harm caused by the splashing broken soil to personnel. Moreover, the mudguard 35 blocks the broken soil, and the broken soil then falls immediately and moves along with the soil-turning plow 37 following the mudguard 35, so that the broken soil in the trench can be turned to both sides.

[0063] The crescent blocks 36 are evenly distributed on the surface of the round roller 32 and close to the inner side of the gantry 31. The position of the soil-turning plow 37 corresponds to the position of the trench-digging teeth 34. By driving the round roller 32 to rotate through the output end of the servo motor 33, the crescent blocks 36 will rotate together with the round roller 32. Using the contact between the crescent blocks 36 and the ends of the right-angle force rods 555, the right-angle force rods 555 are subjected to a driving force towards the frame 553 direction, so that the right-angle force rods 555 can push the frame 553, causing the wire pressing wheel 554 to move towards the side close to the scraper 52, and the support spring piece 551 is compressed. As the crescent blocks 36 separate from the ends of the right-angle force rods 555, the driving force received by the right-angle force rods 555 disappears, and under the elastic force of the support spring piece 551, the frame 553 and the wire pressing wheel 554 move forward together for reset. In this way, through the reciprocating rolling of the wire pressing wheel 554, the cable in the trench is flattened.

[0064] During use, first pass the directly buried cable to be laid through the middle of the wire combing roller 2, and then the wire combing roller 2 can guide and comb the cable, and the wire is bypassed from the bottom of the wire pressing wheel 554 and the bottom of the rolling wheel 53;

[0065] The staff starts the driver 43 to work. Using the driver 43 as the power, through the rotation of the output end of the driver 43, the earth-breaking drill bit 44 can be driven to rotate, and the hydraulic cylinder 42 is started to work. Using the elongation of the telescopic end of the hydraulic cylinder 42, the driver 43 can be driven to move downward, so that the earth-breaking drill bit 44 moves downward together with the driver 43. Then the tip of the earth-breaking drill bit 44 can be used to contact the relatively hard soil. Along with the continuous rotation of the earth-breaking drill bit 44, the soil can be drilled, making the soil drilled and broken, so as to pre-treat the soil;

[0066] After the initial drilling is completed, the hydraulic cylinder 42 can be used again to work. By contracting the telescopic end of the hydraulic cylinder 42, the driver 43 can be lifted, so that the earth-breaking drill bit 44 is separated from the soil. Then, through the elongation and contraction of the telescopic end of the hydraulic cylinder 42, the soil can be continuously drilled and pre-treated;

[0067] At the same time, when the driver 43 moves downward, the guiding square column 45 will be driven to move downward together. Combining the sliding installation between the guiding square column 45 and the support connecting piece 46, the guiding square column 45 can support and guide the driver 43, so that when the earth-breaking drill bit 44 drills and breaks the soil, the overall structure is more stable;

[0068] The staff starts the servo motor 33 to work, and uses the rotation of the output end of the servo motor 33 and the fixed connection of the coupling to drive the round roller 32 to rotate. The trenching teeth 34 will rotate along with the round roller 32, and the trenching teeth 34 can be used to dig trenches on the land that has been drilled and pre-treated by the ground-breaking drill cone 44. The wheels at the bottom of the frame 1 roll, and the entire equipment moves, so that continuous trenching can be carried out.

[0069] The broken soil generated during trenching is shielded by the fender 35, which makes it less likely for the broken soil to splash, thereby reducing the risk of injury to personnel. The fender 35 shields the broken soil, which then falls down and is turned to both sides by the soil turning plow 37 as it moves along with the fender 35.

[0070] The output end of the servo motor 33 drives the round roller 32 to rotate, and the crescent block 36 rotates with the round roller 32. The crescent block 36 contacts the end of the right-angle force-bearing rod 555, so that the right-angle force-bearing rod 555 is subjected to a driving force in the direction of the frame 553. The right-angle force-bearing rod 555 can be used to push the frame 553, so that the pressing wheel 554 moves to the side close to the scraper 52, and the supporting spring piece 551 is compressed. As the crescent block 36 disengages from the end of the right-angle force-bearing rod 555, the driving force on the right-angle force-bearing rod 555 disappears, and under the elastic force of the supporting spring piece 551, the frame 553 and the pressing wheel 554 move forward together to reset. In this way, the cable in the groove is flattened by the reciprocating rolling of the pressing wheel 554.

[0071] Moreover, under the support of the connecting frame 51, the frame 1 moves forward, so that the scraper 52 is driven to move together, and the scraper 52 is V-shaped, so that the broken soil on both sides of the groove can be gathered and scraped into the groove again, so that the cable can be buried. As the scraper 52 drives the rolling wheel 53 to roll, the raised block 54 is used to reduce the contact area with the broken soil, so that the pressure is increased, and the broken soil can be effectively compacted.

[0072] As the wheels at the bottom of the rack 1 roll, the entire device can be moved and the cables can be laid.
