Description

Technical Field

[0001] This invention relates to the field of excavation equipment, specifically to an excavation device for water supply and drainage engineering. Background Technology

[0002] Drainage pipelines refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. They include main pipes, branch pipes and pipes leading to treatment plants. Regardless of whether they are built on streets or anywhere else, as long as they serve the purpose of drainage, when laying drainage pipelines on the ground, it is necessary to first use excavation equipment to dig trenches. Then, the drainage pipelines are placed in the trenches. Most drainage pipelines are made of plastic pipes, and the ends of adjacent drainage pipeline sections need to be fixed by welding. Finally, the soil is backfilled.

[0003] However, when existing water supply and drainage engineering excavation equipment is used, the side walls of the trench are prone to collapse. At the same time, the soil on both sides of the top of the trench is also prone to falling into the trench, affecting the efficiency and effectiveness of trench excavation. Furthermore, after excavation, when the drainage pipe is placed in the trench, it will be at the bottom of the trench, and soil can easily enter the interior through the end of the drainage pipe. This can also cause deformation and damage to the end of the drainage pipe, and make subsequent welding operations inconvenient. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides an excavation device for water supply and drainage engineering.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: a water supply and drainage engineering excavation device, including an excavator body, two symmetrically arranged mounting plates are fixedly connected to the side wall of the excavator body, and a support plate is fixedly connected to the bottom of the mounting plates. A hollow soil storage box is connected to the side wall of the support plate through a rotating mechanism. The soil storage box includes a feeding port and a discharging port. Two symmetrically arranged protective plates are connected to the side wall of the soil storage box through a first telescopic mechanism. The protective plates include arc-shaped sections. A second telescopic mechanism is arranged between the two protective plates. A sealing plate is connected to the bottom of the soil storage box through a moving mechanism. A compaction mechanism for compacting the discharged soil pile is provided on the side wall of the soil storage box. A pushing mechanism for pushing away the soil at the top of the trench is provided on the top of the protective plate.

[0006] The rotating mechanism includes a first connecting block fixedly connected to the side wall of the support plate, and a second connecting block fixedly connected to the side wall of the soil storage box. The top of the first connecting block is rotatably connected to a connecting rod via a first rotating shaft, and the other end of the connecting rod is rotatably connected to the top of the second connecting block via a second rotating shaft.

[0007] The first telescopic mechanism includes multiple arrayed first sleeves fixedly connected to the side wall of the soil storage box, and a first sleeve rod inserted inside the first sleeve. The other end of the first sleeve rod is fixed to the side wall of the protective plate, and a first spring is sleeved on the side wall of the first sleeve.

[0008] The second telescopic mechanism includes two symmetrically arranged second sleeve rods fixedly connected to the side wall of one of the guard plates, and a second sleeve is sleeved on the side wall of the second sleeve rod. The other end of the second sleeve is fixed to the side wall of the guard plate, and a second spring is sleeved on the side wall of the second sleeve.

[0009] The moving mechanism includes a third sleeve fixedly connected to the side wall of the soil storage box, and a third rod inserted inside the third sleeve. The other end of the third rod is fixedly connected to a third connecting block, and the third connecting block is fixed to the top of the sealing plate. The top of the sealing plate is fixedly connected to a fourth connecting block, and a threaded rod is rotatably connected to the side wall of the fourth connecting block. A threaded pipe is threadedly connected to the side wall of the threaded rod, and the other end of the threaded pipe is fixed to the side wall of the soil storage box. A motor is fixedly connected to the side wall of the fourth connecting block, and the output end of the motor is fixed to one end of the threaded rod.

[0010] The compaction mechanism includes two symmetrically arranged baffles fixedly connected to the side wall of the soil storage box, and the side wall of the baffles is rotatably connected to two symmetrically arranged rotating plates via a rotating rod. The rotation of the rotating rod is driven by a driving mechanism.

[0011] The driving mechanism includes a gear fixedly sleeved on the side wall of the rotating rod, and a rack is connected to the side wall of the baffle through a reset mechanism. The rack meshes with the gear, and the movement of the rack is driven by a pushing mechanism.

[0012] The reset mechanism includes two symmetrically arranged fixing blocks fixedly connected to the side wall of the baffle, and two symmetrically arranged guide rods fixedly connected between the two fixing blocks. Each guide rod has a slider sleeved on its side wall, and the slider is fixed to the side wall of the rack. Each guide rod has a third spring sleeved on its side wall.

[0013] The pushing mechanism includes a U-shaped plate fixedly connected to the top of two racks, and an L-shaped pushing plate fixedly connected to the side wall of the fourth connecting block. The pushing plate includes an inclined surface, and the U-shaped plate slides on the inclined surface.

[0014] The pushing mechanism includes a connecting plate fixedly connected to the top of each guard plate, and an inclined plate is fixedly connected to the side wall of the connecting plate.

[0015] The beneficial effects of this invention are: (1) The water supply and drainage engineering excavation equipment of the present invention, by setting a second telescopic mechanism, inserts two guard plates into the trench when excavating the trench. Under the action of the second spring, the two guard plates abut against the two side walls of the trench. At the same time, it can adapt to trenches of different widths. In addition, during the trench excavation process, as the excavator body moves, the support plate is moved by the mounting plate and the soil storage box is moved by the rotating mechanism. Then, the two guard plates are moved along the two side walls of the trench by the first telescopic mechanism, which can compact the side walls and prevent the side walls from collapsing. At the same time, when the guard plates move, the inclined plate is moved synchronously by the connecting plate, which can push the soil on both sides of the top of the trench to the sides and prevent it from falling into the trench, thus ensuring the efficiency and effect of excavation.

[0016] (2) The water supply and drainage engineering excavation equipment of the present invention, by setting a compaction mechanism, etc., during the excavation process, the guard plate and the soil storage box move synchronously with the movement of the excavator body, and under the action of the first spring, the soil storage box is positioned in the middle of the trench. At the same time, it can adapt to trenches of different widths. When the soil storage box moves, the motor is started, and the rotation of the motor drives the rotation of the threaded rod, which in turn drives the sealing plate to move away from the soil storage box, thereby opening the bottom of the discharge port. At this time, the soil in the soil storage box falls to the bottom of the trench through the discharge port to form a soil pile, and the motor is reversed so that the sealing plate seals the bottom of the discharge port. Then, the moving mechanism makes the sealing plate and the fourth connecting block continue to move closer to the soil storage box. At the same time, the movement of the fourth connecting block drives the synchronous movement of the push plate, causing the U-shaped plate to abut against the inclined plane and slide on its surface, thereby pushing the U-shaped plate and rack downward. Simultaneously, the third spring is compressed. When the rack moves downward, it drives the gear and rotating rod to rotate, causing the two rotating plates to move closer to each other and rotate. Under the blocking action of the baffle and rotating plates, the soil pile at the bottom of the trench is compacted. By repeating this process, multiple spaced soil piles can be formed at the bottom of the trench. This allows the drainage pipes to be laid on the soil piles during subsequent laying and welding, so that the ends of the drainage pipes can be tilted upward, preventing soil from entering the interior through the ends of the drainage pipes. This also prevents deformation and damage to the ends of the drainage pipes and facilitates subsequent welding operations. Attached Figure Description

A sealing plate 16 is connected to the bottom of the soil storage box 13 through a moving mechanism. The side wall of the soil storage box 13 is provided with a mechanism for controlling the discharged soil pile. The compaction mechanism, and the top of the protective plate 14, is equipped with a pushing mechanism for pushing away the soil at the top of the trench. During excavation, it can compact the two side walls of the trench to prevent side wall collapse; it can push the soil on both sides of the top of the trench to the sides to prevent it from falling into the trench, ensuring the efficiency and effectiveness of excavation; it can form multiple spaced soil mounds at the bottom of the trench and compact them. When laying and welding drainage pipes later, the drainage pipes can be laid on the soil mounds so that the ends of the drainage pipes can be tilted upwards, which can prevent soil from entering the interior through the ends of the drainage pipes, and at the same time, prevent deformation and damage to the ends of the drainage pipes, and facilitate subsequent welding operations.

[0023] The rotating mechanism includes a first connecting block 201 fixedly connected to the side wall of the support plate 12, and a second connecting block 203 fixedly connected to the side wall of the soil storage box 13. The top of the first connecting block 201 is rotatably connected to a connecting rod 204 via a first rotating shaft 202, and the other end of the connecting rod 204 is rotatably connected to the top of the second connecting block 203 via a second rotating shaft 205. When the excavator body 1 is in operation, the support plate 12 is moved by the mounting plate 11, causing the connecting rod 204 to rotate and pull the soil storage box 13 to move.

[0024] The first telescopic mechanism includes multiple arrayed first sleeves 302 fixedly connected to the side wall of the soil storage box 13, and a first sleeve rod 301 inserted inside the first sleeve 302. The other end of the first sleeve rod 301 is fixed to the side wall of the guard plate 14, and a first spring 303 is sleeved on the side wall of the first sleeve 302. During the excavation process, the guard plate 14 and the soil storage box 13 move synchronously with the movement of the excavator body 1, and under the action of the first spring 303, the soil storage box 13 is positioned in the middle of the trench. At the same time, it can adapt to trenches of different widths.

[0025] The second telescopic mechanism includes two symmetrically arranged second sleeve rods 401 fixedly connected to the side wall of one of the guard plates 14. The side wall of the second sleeve rod 401 is fitted with a second sleeve 402. The other end of the second sleeve 402 is fixed to the side wall of the guard plate 14. The side wall of the second sleeve 402 is fitted with a second spring 403. When digging a trench, the two guard plates 14 are inserted into the trench. Under the action of the second spring 403, the two guard plates 14 abut against the two side walls of the trench. At the same time, it can adapt to trenches of different widths.

[0026] The moving mechanism includes a third sleeve 504 fixedly connected to the side wall of the soil storage box 13, and a third sleeve rod 503 inserted inside the third sleeve 504. The other end of the third sleeve rod 503 is fixedly connected to a third connecting block 501, and the third connecting block 501 is fixed to the top of the sealing plate 16. The top of the sealing plate 16 is fixedly connected to a fourth connecting block 502, and a threaded rod 506 is rotatably connected to the side wall of the fourth connecting block 502. A threaded pipe 505 is threadedly connected to the side wall of the threaded rod 506, and the other end of the threaded pipe 505 is fixed to the side wall of the soil storage box 13. A motor 507 is fixedly connected to the side wall of the fourth connecting block 502, and the output end of the motor 507 is fixed to one end of the threaded rod 506. When the motor 507 is started, the rotation of the motor 507 drives the rotation of the threaded rod 506, thereby driving the sealing plate 16 to move, so as to open or close the bottom of the discharge port 1302.

[0027] The compaction mechanism includes two symmetrically arranged baffles 601 fixedly connected to the side wall of the soil storage box 13. The side wall of the baffles 601 is rotatably connected to two symmetrically arranged rotating plates 603 via a rotating rod 602. The rotation of the rotating rod 602 is driven by a driving mechanism. After the soil in the soil storage box 13 falls to the bottom of the trench through the discharge port 1302 and forms a soil pile, the rotating rod 602 is driven to rotate by the driving mechanism, which causes the two rotating plates 603 to move closer to each other and rotate. Under the blocking action of the baffles 601 and the rotating plates 603, the soil pile at the bottom of the trench is compacted.

[0028] The drive mechanism includes a gear 701 fixedly sleeved on the side wall of the rotating rod 602, and a rack 702 connected to the side wall of the baffle 601 through a reset mechanism. The rack 702 is meshed with the gear 701, and the movement of the rack 702 is driven by a pushing mechanism. The pushing mechanism pushes the rack 702 to move downward. When the rack 702 moves downward, it drives the gear 701 and the rotating rod 602 to rotate.

[0029] The reset mechanism includes two symmetrically arranged fixing blocks 801 fixedly connected to the side wall of the baffle 601, and two symmetrically arranged guide rods 802 fixedly connected between the two fixing blocks 801. A slider 803 is sleeved on the side wall of each guide rod 802, and the slider 803 is fixed to the side wall of the rack 702. A third spring 804 is sleeved on the side wall of each guide rod 802, which guides and resets the movement of the rack 702.

[0030] The pushing mechanism includes a U-shaped plate 901 fixedly connected to the top of the two racks 702, and an L-shaped pushing plate 902 fixedly connected to the side wall of the fourth connecting block 502. The pushing plate 902 includes an inclined surface 903, and the U-shaped plate 901 slides on the inclined surface 903. The sealing plate 16 seals the bottom of the discharge port 1302. Then, the moving mechanism causes the sealing plate 16 and the fourth connecting block 502 to continue moving towards the soil storage box 13. At the same time, the movement of the fourth connecting block 502 drives the synchronous movement of the pushing plate 902, so that the U-shaped plate 901 abuts against the inclined surface 903 and slides on its surface, thereby pushing the U-shaped plate 901 and the rack 702 to move downward.

[0031] The pushing mechanism includes a connecting plate 1001 fixedly connected to the top of each guard plate 14, and an inclined plate 1002 fixedly connected to the side wall of the connecting plate 1001. When the guard plate 14 moves, the inclined plate 1002 moves synchronously through the connecting plate 1001, which can push the soil on both sides of the top of the trench to the sides to prevent it from falling into the trench and ensure the efficiency and effect of excavation.

[0032] Working principle: During operation, firstly, when excavating a trench, two guard plates 14 are inserted into the trench. Under the action of the second spring 403, the two guard plates 14 abut against the two side walls of the trench. At the same time, it can adapt to trenches of different widths. During the trench excavation process, as the excavator body 1 moves, the mounting plate 11 drives the support plate 12 to move, and the rotating mechanism drives the soil storage box 13 to move. Then, the first telescopic mechanism drives the two guard plates 14 to move along the two side walls of the trench, which can compact the side walls and prevent them from collapsing. At the same time, when the guard plates 14 move, the connecting plate 1001 drives the inclined plate 1002 to move synchronously, which can push the soil on both sides of the top of the trench to the sides to prevent it from falling into the trench, thus ensuring the efficiency and effect of excavation. Meanwhile, during the excavation process, the guard plate 14 and the soil storage box 13 move synchronously with the excavator body 1. Under the action of the first spring 303, the soil storage box 13 is positioned in the middle of the trench. It can also adapt to trenches of different widths. When the soil storage box 13 moves, the motor 507 is started. The rotation of the motor 507 drives the rotation of the threaded rod 506, which in turn drives the sealing plate 16 to move away from the soil storage box 13, thereby opening the bottom of the discharge port 1302. At this time, the soil in the soil storage box 13 falls to the bottom of the trench through the discharge port 1302 to form a soil pile. The motor 507 is then reversed, causing the sealing plate 16 to seal the bottom of the discharge port 1302. Next, the moving mechanism causes the sealing plate 16 and the fourth connecting block 502 to continue moving closer to the soil storage box 13. At the same time, the movement of the fourth connecting block 502 drives the push plate 902 to move synchronously, causing the U-shaped plate 901 to abut against the inclined surface 903 and slide on its surface, thereby pushing the U-shaped plate 901 and the rack 702 to move downward. Meanwhile, the third spring 804 is compressed. When the rack 702 moves downward, it pushes the gear 701 and the rotating rod 602 to rotate, thereby causing the two rotating plates 603 to move closer to each other and rotate. Under the blocking action of the baffle 601 and the rotating plate 603, the soil pile at the bottom of the trench is compacted. By repeating this process, multiple spaced soil piles can be formed at the bottom of the trench. This allows the drainage pipes to be laid on the soil piles during subsequent laying and welding, so that the ends of the drainage pipes can be tilted upward, preventing soil from entering the interior through the ends of the drainage pipes. This also prevents deformation and damage to the ends of the drainage pipes and facilitates subsequent welding operations.
