Description

Technical Field

[0001] This invention relates to the field of pipeline excavation equipment technology, specifically to an automated excavation device for municipal pipeline trenches. Background Technology

[0002] Municipal pipeline excavation equipment is used in municipal engineering to excavate trenches for laying underground pipelines (such as drainage pipes, gas pipes, cables, etc.). These devices are commonly referred to as trenchers, ditch diggers, or pipeline excavation machinery. Their core function is to precisely excavate trenches of the required depth and width in different soil layers, such as soil and asphalt pavement, using operating methods such as chains, discs, or hydraulics.

[0003] In the existing technology, during the process of using a trenching device to dig a trench in the ground, the large friction between the trenching device and the ground will cause the trenching device to vibrate. This will result in unevenness inside the trench, thereby reducing the quality of the trench. Summary of the Invention

[0004] The purpose of this invention is to provide an automated excavation device for municipal pipeline trenches to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an automated excavation device for municipal pipeline trenches, comprising a mobile vehicle, with protective rings fixedly connected to both sides of the mobile vehicle, wheels provided at the bottom of the mobile vehicle, and a motor fixedly connected to the surface of the mobile vehicle; characterized in that it further comprises; An adjustment mechanism, comprising a movable plate, wherein a supporting elastic rod and an electric telescopic rod are fixedly connected to the bottom of the movable plate; A stabilizing mechanism, comprising a carriage, a stabilizing plate fixedly connected to the end of the carriage, and a push rod hinged to the bottom of the carriage; A trenching mechanism, comprising a drive wheel, a rotating shaft fixedly connected to the surface of the drive wheel, and an auger ring fixedly connected to the surface of the rotating shaft.

[0009] Furthermore, the stabilizing mechanism includes a T-shaped plate, a grooved rod fixedly connected to the end of the T-shaped plate, a driven slide plate slidably connected to the inner wall of the grooved rod, a grooved plate fixedly connected to the bottom of the driven slide plate, a driven telescopic rod fixedly connected to the inner wall of the driven slide plate, a limit spring fixedly connected to the inner wall of the grooved rod, and a connecting plate fixedly connected to the top of the inner wall of the T-shaped plate.

[0010] Furthermore, the end of the T-shaped plate away from the grooved rod is slidably connected to the top of the slide plate; the end of the driven telescopic rod away from the driven slide plate is fixedly connected to the surface of the driven bending plate; the surface of the grooved plate is slidably connected to the inner wall of the grooved rod; the surface of the slide is slidably connected to the inner wall of the grooved plate; the end of the push rod away from the limiting spring is hinged to the end of the grooved rod; the bottom of the grooved plate is fixedly connected to the top of the limiting spring; and the end of the connecting plate away from the inner wall of the T-shaped plate is fixedly connected to the top of the slide plate.

[0011] Furthermore, the grooving mechanism includes a support plate, with guide plates and baffles fixedly connected to both sides of the support plate. A feed hopper is fixedly connected to the bottom of the guide plate. A power device is fixedly connected to the surface of the support plate. A drive shaft is fixedly connected to the output end of the power device. A gear plate and a rotating wheel are fixedly connected to the surface of the drive shaft. A power chain is provided on the inner wall of the support plate. A slotted plate is fixedly connected to the surface of the power chain. A drive belt is driven to the inner wall of the rotating wheel.

[0012] Furthermore, the end of the driven bending plate away from the moving plate is fixedly connected to the top of the guide plate, the surface of the gear disc meshes with the inner wall of the power chain, the end of the transmission belt away from the rotating wheel is connected to the inner wall of the power wheel, and the outer wall of the auger ring contacts the inner wall of the feed hopper.

[0013] The present invention has the following beneficial effects: This invention employs an adjustment mechanism. First, the motor drives the threaded rod in a forward direction, causing the threaded ring to move towards the motor. As the threaded ring moves, it causes the sliding plate to slide along the inner wall of the grooving plate towards the motor. This sliding motion of the sliding plate, along with the supporting elastic rod and the electric telescopic rod, moves the moving plate towards the motor. The moving plate then causes the driven bending plate to move towards the motor, which in turn moves the entire grooving mechanism towards the motor, positioning it at the desired grooving location. When the motor drives the threaded rod in a reverse direction, the entire grooving mechanism can be moved in the opposite direction, thus allowing for adjustment of the grooving mechanism. Upon reaching the designated position, when the trenching mechanism moves to the desired trenching location, the electric telescopic rod is activated to pull the moving plate downwards along the inner wall of the slide plate. As the moving plate slides downwards, it compresses the supporting elastic rod, causing it to contract downwards. Simultaneously, the moving plate also drives the driven bending plate downwards. As the driven bending plate moves downwards, it drives the entire trenching mechanism downwards, bringing the trenching plate into contact with the ground. This effectively moves the slide plate via the threaded rod, allowing for positional adjustment of the entire trenching mechanism to the desired trenching location. Furthermore, the pulling force of the electric telescopic rod can also be used to adjust the overall function of the trenching mechanism.

[0014] This invention employs a stabilizing mechanism. When the sliding plate moves towards the motor, it causes the connecting plate to move towards the motor. The moving connecting plate, in turn, causes the T-shaped plate to slide towards the motor from the top of the sliding groove plate. The moving T-shaped plate, in turn, causes the grooved rod to move towards the motor. The moving grooved rod, in turn, causes the driven sliding plate, grooved plate, driven telescopic rod, and carriage to move towards the motor. The moving carriage, in turn, causes the stabilizing plate to move towards the motor. Simultaneously, the moving grooved rod causes the push rod and limit spring to move towards the motor. When the sliding plate moves in the opposite direction to the motor, the entire stabilizing mechanism moves in the opposite direction. When the driven curved plate moves downward, it causes the driven telescopic rod to move downward. The downward movement of the driven telescopic rod causes the driven sliding plate to slide downward along the inner wall of the grooved rod. When the slide plate slides, it pushes the grooved plate downwards along the inner wall of the grooved rod. This movement of the grooved plate causes the carriage to move downwards, which in turn pushes the end of the push rod downwards. Because the push rod and carriage are angled, the downward movement of the push rod pushes the carriage to slide closer together along the inner wall of the grooved plate. This movement of the carriage also pushes the stabilizing plate closer together, causing it to contact the surface of the support plate. This stabilizes the entire grooving mechanism. Simultaneously, the grooved plate slides downwards, compressing the limiting spring and effectively reinforcing the support plate by ensuring it contacts the surface during movement. This makes the grooving mechanism more stable during the grooving process, ensuring the flatness of the groove and improving the quality of the grooving.

[0015] This invention employs a grooving mechanism. When the grooving plate contacts the ground, a power unit is activated to drive the transmission shaft to rotate. The rotation of the transmission shaft simultaneously drives a geared disc and a rotating wheel. The rotation of the geared disc drives a power chain, which in turn drives the grooving plate. During this rotation, the grooving plate grooves the ground, and the resulting soil is transmitted through the grooving plate to the inner wall of a guide plate. The guide plate then guides the soil into the feed hopper. The rotating wheel drives a transmission belt, which in turn drives a power wheel, which in turn drives a rotating shaft. This shaft, in turn, drives an auger ring, which transports the soil from the feed hopper to the ground. This effectively prevents the grooving plate from falling into the trough during rotation.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-10 As shown, the present invention is an automated excavation device for municipal pipeline trenches, including a mobile vehicle 1, protective rings 2 fixedly connected to both sides of the mobile vehicle 1, mobile wheels 3 provided at the bottom of the mobile vehicle 1, and a motor 4 fixedly connected to the surface of the mobile vehicle 1. The invention is characterized by further comprising: The adjustment mechanism 10 includes a movable plate 13. When the movable plate 13 moves, it will drive the driven bending plate 14 to move in the direction of the motor 4. When the driven bending plate 14 moves, it will drive the grooving mechanism 50 to move in the direction of the motor 4, moving the grooving mechanism 50 to the position where grooving is required. When the motor 4 drives the threaded rod 17 to reverse, the grooving mechanism 50 can be moved in the opposite direction of the motor 4, thereby adjusting the grooving mechanism 50 to the specified position. The bottom of the movable plate 13 is fixedly connected with a support elastic rod 15 and an electric telescopic rod 16. The stabilizing mechanism 30 includes a slide 36, with a stabilizing plate 37 fixedly connected to the end of the slide 36 and a push rod 38 hinged to the bottom of the slide 36. The trenching mechanism 50 includes a drive wheel 62, a rotating shaft 63 fixedly connected to the surface of the drive wheel 62, and an auger ring 64 fixedly connected to the surface of the rotating shaft 63.

[0022] There are four movable wheels 3, which are symmetrically arranged around the movable vehicle 1. There are also four protective rings 2, which are divided into two groups of two each, and are symmetrically arranged.

[0023] The adjusting mechanism 10 includes a slide plate 11, a slide plate 12 slidably connected to the inner wall of the slide plate 11, driven bent plates 14 fixedly connected to both sides of the moving plate 13, and a threaded rod 17 fixedly connected to the output end of the motor 4. A threaded ring 18 is threadedly connected to the surface of the threaded rod 17. First, the motor 4 is started to drive the threaded rod 17 to rotate forward and drive the threaded ring 18 to move in the direction of the motor 4. When the threaded ring 18 moves, it will drive the slide plate 12 to slide in the direction of the motor 4 on the inner wall of the slide plate 11. When the slide plate 12 slides, it will drive the moving plate 13, the supporting elastic rod 15, and the electric telescopic rod 16 to move in the direction of the motor 4. By effectively moving the slide plate 12 through the threaded rod 17, the position of the entire trenching mechanism 50 can be adjusted, thereby adjusting the entire trenching mechanism 50 to the position where trenching is required. At the same time, the pulling force of the electric telescopic rod 16 can also adjust the overall function of the trenching mechanism 50.

[0024] The surface of the grooving plate 11 is fixedly connected to the end of the moving vehicle 1. Grooves are provided on both sides of the sliding plate 12. The surface of the moving plate 13 is slidably connected to the inner wall of the groove. The end of the supporting elastic rod 15 away from the moving plate 13 is fixedly connected to the surface of the sliding plate 12. The surface of the threaded ring 18 is fixedly connected to the surface of the sliding plate 12. When the grooving mechanism 50 moves to the position where grooving is required, the electric telescopic rod 16 is activated to pull the moving plate 13 to slide downward on the inner wall of the sliding plate 12. When the moving plate 13 slides downward, it will squeeze the supporting elastic rod 15, causing the supporting elastic rod 15 to retract downward. At the same time, the moving plate 13 will also drive the driven bending plate 14 to move downward. When the driven bending plate 14 moves downward, it will drive the grooving mechanism 50 to move downward as a whole, so that the grooving plate 60 contacts the ground.

[0025] The stabilizing mechanism 30 includes a T-shaped plate 31. A grooved rod 32 is fixedly connected to the end of the T-shaped plate 31. A driven slide plate 33 is slidably connected to the inner wall of the grooved rod 32. A grooved plate 34 is fixedly connected to the bottom of the driven slide plate 33. A driven telescopic rod 35 is fixedly connected to the inner wall of the driven slide plate 33. A limit spring 39 is fixedly connected to the inner wall of the grooved rod 32. A connecting plate 40 is fixedly connected to the top of the inner wall of the T-shaped plate 31. When the driven slide plate 12 moves in the opposite direction to the motor 4, it will drive the entire stabilizing mechanism 30 to move in the opposite direction to the motor 4. When the driven bent plate 14 moves downward, it will drive the driven telescopic rod 35 to move downward. When the driven telescopic rod 35 moves downward, it will drive the driven slide plate 33 to slide downward on the inner wall of the grooved rod 32. When the driven slide plate 33 slides, it will push the grooved plate 34 to slide downward on the inner wall of the grooved rod 32. 4. When sliding, the slide 36 will move downwards. When the slide 36 moves, it will push the end of the push rod 38 downwards. Since the push rod 38 and the slide 36 are set at an angle, during the downward movement of the end of the push rod 38, the slide 36 will be pushed to slide closer to each other on the inner wall of the groove plate 34. When the slide 36 slides, it will push the stabilizing plate 37 to move closer to each other, so that the stabilizing plate 37 contacts the surface of the support plate 51, thereby stabilizing the entire grooving mechanism 50. When the groove plate 34 slides downwards, it will compress the limiting spring 39 to retract downwards. This effectively ensures that the stabilizing plate 37 contacts the surface of the support plate 51 during the movement and reinforces the support plate 51, making the entire grooving mechanism 50 more stable during the grooving process, thus ensuring the flatness of the groove and improving the quality of grooving.

[0026] The end of the T-shaped plate 31 away from the grooved rod 32 is slidably connected to the top of the slide plate 11. The end of the driven telescopic rod 35 away from the driven slide plate 33 is fixedly connected to the surface of the driven bent plate 14. The surface of the grooved plate 34 is slidably connected to the inner wall of the grooved rod 32. The surface of the slide 36 is slidably connected to the inner wall of the grooved plate 34. The end of the push rod 38 away from the limiting spring 39 is hinged to the end of the grooved rod 32. When the slide plate 12 moves toward the motor 4, it will drive the connecting plate 40 to move toward the motor 4. When the connecting plate 40 moves, it will drive the T-shaped plate 31 at the top of the slide plate 11 toward the motor. Sliding in direction 4, when the T-shaped plate 31 moves, it will drive the grooved rod 32 to move in the direction of motor 4. When the grooved rod 32 moves, it will drive the driven slide plate 33, grooved plate 34, driven telescopic rod 35 and slide 36 to move in the direction of motor 4. When the slide 36 moves, it will drive the stabilizing plate 37 to move in the direction of motor 4. At the same time as the grooved rod 32 moves, it will drive the push rod 38 and the limiting spring 39 to move in the direction of motor 4. The bottom of the grooved plate 34 is fixedly connected to the top of the limiting spring 39. The end of the connecting plate 40 away from the inner wall of the T-shaped plate 31 is fixedly connected to the top of the slide plate 12.

[0027] The grooving mechanism 50 includes a support plate 51. Guide plates 52 and baffles 53 are fixedly connected to both sides of the support plate 51. A feed hopper 54 is fixedly connected to the bottom of the guide plates 52. A power unit 55 is fixedly connected to the surface of the support plate 51. A drive shaft 56 is fixedly connected to the output end of the power unit 55. A gear disc 57 and a rotating wheel 58 are fixedly connected to the surface of the drive shaft 56. A power chain 59 is provided on the inner wall of the support plate 51. A slotted plate 60 is fixedly connected to the surface of the power chain 59. A drive belt 61 is driven through the inner wall of the rotating wheel 58. When the rotating wheel 58 rotates, it drives the transmission belt 60. The drive belt 61 rotates, which in turn drives the power wheel 62 to rotate. The power wheel 62 rotates, which in turn drives the shaft 63 to rotate. The shaft 63 rotates, which in turn drives the auger ring 64 to rotate. During the rotation of the auger ring 64, the soil inside the feed hopper 54 is transported to the ground. The grooving plate 60 can effectively dig a trench in the ground during its rotation. The soil generated during the trenching is transported to the inside of the feed hopper 54 through the grooving plate 60. Finally, the auger ring 64 transports the soil generated during the trenching to the ground, thus preventing the soil from falling into the trench.

[0028] The end of the driven bending plate 14 away from the moving plate 13 is fixedly connected to the top of the guide plate 52. The surface of the toothed disc 57 meshes with the inner wall of the power chain 59. The end of the transmission belt 61 away from the rotating wheel 58 is connected to the inner wall of the power wheel 62. The outer wall of the auger ring 64 contacts the inner wall of the feed hopper 54. When the grooving plate 60 contacts the ground, the power device 55 is started to drive the transmission shaft 56 to rotate. When the transmission shaft 56 rotates, it will simultaneously drive the toothed disc 57 and the rotating wheel 58 to rotate. When the toothed disc 57 rotates, it will drive the power chain 59 to rotate. When the power chain 59 rotates, it will drive the grooving plate 60 to rotate. During the rotation of the grooving plate 60, it will dig a groove in the ground. The soil generated by the grooving will be transmitted through the grooving plate 60 to the inner wall of the guide plate 52, and then guided by the guide plate 52, the soil will fall into the interior of the feed hopper 54.

[0029] In use, first, start motor 4 to drive threaded rod 17 in a forward direction, causing threaded ring 18 to move towards motor 4. As threaded ring 18 moves, it causes slide plate 12 to slide along the inner wall of slide plate 11 towards motor 4. When slide plate 12 slides, it causes moving plate 13, supporting elastic rod 15, and electric telescopic rod 16 to move towards motor 4. When moving plate 13 moves, it causes driven bending plate 14 to move towards motor 4. When driven bending plate 14 moves, it causes the entire grooving mechanism 50 to move towards motor 4, moving the entire grooving mechanism 50 to the desired grooving position. When motor 4 drives threaded rod 17 in a reverse direction, the entire grooving mechanism 50 can be moved in the opposite direction to motor 4, thereby adjusting the grooving mechanism 50 to reach the desired grooving position. At the designated location, when the grooving mechanism 50 moves to the desired grooving position, the electric telescopic rod 16 is activated to pull the moving plate 13 downwards along the inner wall of the slide plate 12. As the moving plate 13 slides downwards, it compresses the supporting elastic rod 15, causing it to contract downwards. Simultaneously, the moving plate 13 also drives the driven bending plate 14 downwards. This downward movement of the driven bending plate 14 causes the entire grooving mechanism 50 to move downwards, bringing the grooving plate 60 into contact with the ground. When the slide plate 12 moves towards the motor 4, it drives the connecting plate 40 towards the motor 4. The movement of the connecting plate 40 causes the T-shaped plate 31 to slide towards the motor 4 from the top of the grooving plate 11. The movement of the T-shaped plate 31 then drives the grooved rod 32 towards the motor 4. When the grooved rod 32 moves, it drives the driven slide plate 33, grooved plate 34, driven telescopic rod 35, and carriage 36 to move towards the motor 4. When the carriage 36 moves, it drives the stabilizing plate 37 to move towards the motor 4. Simultaneously, the grooved rod 32 moves, driving the push rod 38 and limit spring 39 to move towards the motor 4. When the slide plate 12 moves in the opposite direction to the motor 4, it drives the stabilizing mechanism 30 to move in the opposite direction to the motor 4. When the driven bent plate 14 moves downward, it drives the driven telescopic rod 35 downward. When the driven telescopic rod 35 moves downward, it drives the driven slide plate 33 to slide downward on the inner wall of the grooved rod 32. As the driven slide plate 33 slides, it pushes the grooved plate 34 to slide downward on the inner wall of the grooved rod 32. When plate 34 slides, it causes slide 36 to move downwards. When slide 36 moves, it pushes the end of push rod 38 downwards. Since push rod 38 and slide 36 are set at an angle, during the downward movement of the end of push rod 38, slide 36 against the inner wall of groove plate 34, moving them closer together. When slide 36 slides, it pushes stabilizing plate 37, causing it to contact the surface of support plate 51, thus stabilizing the entire grooving mechanism 50. As groove plate 34 slides downwards, it compresses limit spring 39, causing it to contract downwards. When grooving plate 60 contacts the ground, power device 55 is activated, driving drive shaft 56 to rotate. When drive shaft 56 rotates, it simultaneously drives gear disc 57 and rotating wheel 58 to rotate.When the gear disc 57 rotates, it drives the drive chain 59 to rotate. The drive chain 59, in turn, drives the slotting plate 60 to rotate. During the rotation of the slotting plate 60, a groove is dug in the ground. The soil created during this digging is transmitted through the slotting plate 60 to the inner wall of the guide plate 52. The guide plate 52 then guides the soil into the feed hopper 54. When the rotating wheel 58 rotates, it drives the transmission belt 61 to rotate. The transmission belt 61, in turn, drives the drive wheel 62 to rotate. The drive wheel 62, in turn, drives the rotating shaft 63 to rotate. The rotating shaft 63, in turn, drives the auger ring 64 to rotate. During the rotation of the auger ring 64, the soil inside the feed hopper 54 is transported, and finally, the soil is transported to the ground.
