Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of track suspension conveying, in particular to a deep foundation pit earthwork intelligent conveying system based on track suspension. BACKGROUND

[0002] Due to the deepness of the deep foundation pit, the traditional conveying belt has obvious limitations in earthwork conveying. From the perspective of conveying, the large height difference of the deep foundation pit requires the setting of an ultra-long inclined section or a multi-stage transfer structure for the conveying belt, which greatly increases the complexity of equipment installation. The track suspension conveying of deep foundation pit earthwork is a high-efficiency transportation method for special working conditions. The core principle is to move the hopper loaded with earthwork along the suspended track system fixed above the foundation pit to realize the transportation of earthwork from the pit bottom to the ground. This method is suitable for deep foundation pit scenes with narrow space and is difficult for belt conveyors to operate, especially in urban core areas and surrounding densely built projects.

[0003] In the track suspension conveying system, the hopper is usually used to load, convey and unload the earthwork. In the unloading process, the hopper is moved to the top of the carriage of the muck car by the track suspension conveying system, the unloading port at the bottom of the hopper is opened, and the earthwork falls into the carriage of the muck car to realize unloading operation. However, the track suspension conveying system moves the hopper to the designated position for unloading each time, which is prone to cause the accumulation of earthwork under the hopper, forming a small slope state, causing the subsequent falling earthwork to slide outward along the slope, making it difficult to evenly fill the carriage space, and prone to loading unbalance, which requires frequent suspension of operation for manual leveling, seriously affecting the unloading efficiency. In view of this, we propose a deep foundation pit earthwork intelligent conveying system based on track suspension. SUMMARY

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention features a hopper arranged on a suspended track, with multiple drop plates and side drop plates designed on the hopper. These can be combined to form drop channels or side drop channels. In the initial stage of unloading, the hopper can unload through the drop channels, causing soil and rocks to accumulate below the hopper. When the accumulation reaches a certain level, the drop channels are closed and the side drop channels are opened by changing the drop plates and side drop plates. At this time, the hopper outputs soil and rocks evenly to both sides through the side drop channels, avoiding the accumulation of soil in one place in the truck bed, which would cause difficulties in subsequent unloading. This invention solves the problems of single unloading direction, easy loading imbalance, and low unloading efficiency in traditional deep foundation pit earthwork transportation, and improves the intelligence of deep foundation pit earthwork transportation.

[0017] 2. This invention designs a diversion block with two symmetrical inclined surfaces at the top. When soil is loaded into the hopper, the inclined surfaces guide the soil and rocks above to flow evenly along both sides, preventing soil from accumulating in the hopper and ensuring a balanced distribution of soil and rocks during subsequent unloading. When either the drop channel or the side drop channel is opened, the corresponding support structure is released. The unsupported soil and rocks will naturally exit along the opened channel under their own gravity, achieving unloading without additional power. The two inclined surfaces at the top of the diversion block do not provide support for the soil and rocks, but only provide a guiding function, simplifying the unloading mechanism, ensuring the continuity and smoothness of soil and rock output, and effectively improving the unloading efficiency of the hopper.

[0018] 3. This invention designs an auxiliary feeding component. When the hopper is discharging material, the motor drives the rotating disc to rotate via a chain and sprocket assembly, which in turn drives the lifting pipe to descend rapidly. The lifting pipe, through a spring and a water storage pipe, drives the pressure rod to descend rapidly, allowing the pressure rod to press down on the soil in the hopper, applying downward pressure. This allows the soil to be quickly output along the two inclined surfaces at the top of the diversion block into the open drop channel or the open side drop channel. By designing the pressure rod as a frustum structure, the bottom area of ​​the pressure rod is large, allowing for extensive contact with the soil in the hopper. This enables the pressure to be applied evenly to the soil below, improving the efficiency of soil output and avoiding localized pressure concentration that reduces the pushing effect on the soil. This solves the problem of blockage caused by slow soil output during the feeding process.

[0019] 4. This invention also connects the pressure rod and the limiting plate with a spring. When the pressure rod encounters significant resistance on the soil, exceeding the elastic deformation range of the spring, the pressure rod stops pressing down. The lifting pipe continues to descend and slides relative to the pressure rod, causing the piercing rod connected to its bottom to extend from the inner cavity of the pressure rod. This pierces and breaks up the soil with significant resistance. On the one hand, this avoids the problem of equipment damage caused by continuing to force the pressure rod down when the resistance is significant. On the other hand, it allows the piercing rod to pierce and break up the soil with significant resistance, dispersing soil clumps, removing blockages, and allowing the soil to be smoothly output along the falling channel or side falling channel under the continuous thrust of the pressure rod.

[0020] 5. This invention also incorporates a water storage pipe design. Water is continuously injected into the storage tank of the pipe via an external water injection device, filling the tank to a high pressure. Some of the water is sprayed out through atomizing nozzles at the bottom of the outer circumference of the water pipe, forming a misting water curtain. This misting water curtain effectively suppresses dust generated during earthwork unloading, reducing dust pollution to the working environment. Simultaneously, when the pressure bar encounters significant resistance on the earthwork, it stops pressing down, while the lifting pipe continues to descend and slides relative to the pressure bar, driving its bottom... The piercing rod, connected to the core, extends from the inner cavity of the pressure rod to pierce and break up soil with high resistance. During this process, as the lifting pipe descends, the pressure block connected to its outer circumference slides synchronously within the water storage chamber, squeezing the water inside. Furthermore, the piercing rod extends from the inner cavity of the pressure rod, opening the water spray channel between the lifting pipe and the pressure rod. This allows some water to flow out through the spray channel, wetting the soil in the hopper and softening the clumps. This makes it easier for the piercing rod to penetrate the soil, thus more easily breaking up the clumps and blockages. Attached Figure Description

[0039] like Figures 1 to 13 As shown, the present invention relates to an intelligent earthmoving system for deep foundation pits based on track suspension, comprising a steel frame 1, which is a conventional load-bearing foundation as described in the example, and is fixed to the ground around the foundation pit by pre-embedded bolts. A suspended track 2 is installed on the top of the steel frame 1, and a hopper 4 is connected to the suspended track 2 via a drive device 3. Two symmetrically arranged auxiliary unloading components 5 are also installed on the top of the steel frame 1. The hopper 4 includes multiple drop plates 401 and multiple side drop plates 402, and the drop plates 401 and side drop plates 402... 2 can be combined to form a drop channel or a side drop channel; the drop channel is used to vertically output the soil in the hopper 4 downwards; the side drop channel is used to output the soil in the hopper 4 to the side; the auxiliary feeding component 5 includes multiple pressure rods 501, and a pawing rod 502 is movably arranged in the inner cavity of the pressure rod 501. The pressure rod 501 has a frustum structure. The pressure rod 501 can push the soil in the hopper 4 downwards to make the soil output smoothly. When the soil is severely blocked, the pawing rod 502 can break up the soil and relieve the blockage. The drive unit 3 on the suspended track 2 drives the hopper 4 to the loading position. After the soil is loaded, the drive unit 3 transports the hopper 4 to the unloading area. During unloading, the drop plate 401 and the side drop plate 402 of the hopper 4 can be combined to form a drop channel or a side drop channel. In the initial stage of unloading, the soil is first output through the drop channel and accumulates in the truck bed. Then it is output through the side drop channel, so that the soil is evenly distributed in the truck bed and avoids the soil from accumulating on one side of the truck bed and causing uneven loading. During this period, the auxiliary feeding component 5 on the top of the steel frame 1 is activated. The pressure rod 501 of the truncated cone structure pushes the soil in the hopper downward to ensure smooth output. If a serious blockage occurs, the piercing rod 502 in the inner cavity of the pressure rod 501 extends to break the soil, thereby relieving the blockage and completing the intelligent transportation of soil in the deep foundation pit.

[0040] In an embodiment of the present invention, the suspended track 2 is a ring-shaped track structure with an I-shaped track cross section; the drive device 3 includes a bracket, and a pulley 301 driven by a motor is installed on the top of the bracket, the pulley 301 rollingly engaging with the suspended track 2; a winch 302 is installed inside the bracket, the winch 302 is prior art in this example and will not be described in detail, the output end of the winch 302 is connected to an anti-disengagement hook 303 via a wire rope, the anti-disengagement hook 303 is used to connect to the hopper 4, and the winch 302 is used to vertically lift the hopper 4; the hopper 4 also includes a frame 403, the inner side wall of the frame 403 is connected to a diverter block 404 and a fixed base frame 405, and the top of the frame 403 is connected to multiple hanging rings 406, the anti-disengagement hook 303 is movably connected to the hanging rings 406. The suspended track 2 provides path support for the entire transportation process. When the motor of the drive device 3 is working, it drives the pulley 301 to move along the path of the suspended track 2, thereby driving the connected hopper 4 to adjust its horizontal position, so that it can move cyclically along the circular track to the designated positions such as the loading point and unloading point. The winch 302 winds up and unwinds the wire rope at the output end, and with the help of the anti-disengagement hook 303 connected to the end of the wire rope, it drives the hopper 4 to complete the vertical lifting or lowering action, so that the hopper 4 can be lowered into the deep foundation pit for loading.

[0041] In another embodiment of the present invention, the drop plate 401 is arranged below the diversion block 404, and the side wall of the drop plate 401 is rotatably engaged with the inner side wall of the frame 403 through a pivot 407; there are two drop plates 401, and the two drop plates 401 are arranged in a symmetrical structure. One of the drop plates 401 is rotatably connected to the bottom of a push-pull rod 408. A cylinder 409 is installed in the fixed base frame 405, and the output end of the cylinder 409 is connected to a push-pull frame 410. One end of the push-pull rod 408 is rotatably connected to the push-pull frame 410. When the state of the lower plate 401 needs to be adjusted, the cylinder 409 in the fixed base frame 405 is activated, and its output end drives the push-pull frame 410 to extend and retract. The push-pull frame 410 drives one of the lower plates 401 to rotate around the rotating shaft 407 through the push-pull rod 408 rotatably connected to it. Since the two lower plates 401 are symmetrically arranged and linked, the synchronous rotation of the two lower plates 401 is achieved to complete the formation or closure of the lowering channel and meet the control requirements of vertical earthwork output.

[0042] In another embodiment of the present invention, there are two side landing plates 402, which are arranged symmetrically. The side walls of the side landing plates 402 are rotatably mounted on the side wall of the frame 403 via a second rotating shaft 411. The side walls of the side landing plates 402 are also connected to drive columns 412. The side wall of the frame 403 has an annular groove 413, the center of which is the same as that of the second rotating shaft 411, to ensure that the drive column 412 connected to the side wall of the side landing plate 402 can perform circular motion with the second rotating shaft 411 as the center during rotation. The drive column 412 is movably arranged in the annular groove 413. The side wall of the frame 403 is provided with a slide rail 414 and a second cylinder 415. A lifting plate 416 is slidably arranged on the top. The output end of cylinder 415 is connected to the top of the lifting plate 416. A movable groove 417 is opened on the side wall of the lifting plate 416, and the drive column 412 is movably arranged in the movable groove 417. The frame 403, multiple drop plates 401 and multiple side drop plates 402 together enclose to form a hopper, which is used to hold earthwork. When the side drop plates 402 are kept in the enclosed state and the drop plates 401 are rotated to form a vertical state, a falling channel is formed between the drop plates 401 and the side drop plates 402. When the drop plates 401 are kept in the enclosed state and the side drop plates 402 are rotated to form an inclined state, a side falling channel is formed above the drop plates 401 and the side drop plates 402. Two symmetrically arranged side drop plates 402 are rotatably connected to the side wall of the frame 403 via a second rotating shaft 411. The drive column 412 of the side wall is simultaneously placed in the annular groove 413 of the frame 403 and the movable groove 417 of the lifting plate 416. When it is necessary to adjust the state of the side drop plates 402, the second cylinder 415 of the side wall of the frame 403 drives the lifting plate 416 to rise and fall along the slide rail 414. The lifting plate 416 drives the drive column 412 to slide in the annular groove 413 through the movable groove 417, so that the two side drop plates 402 rotate synchronously around the second rotating shaft 411. When the side drop plates 402 are closed, they cooperate with the vertical drop plate 401 to form a falling channel. When the drop plate 401 is closed and the side drop plates 402 are rotated to an inclined state, they form a side falling channel with the drop plate 401 above, realizing the control of the lateral output of soil in the silo.

[0043] This invention features a hopper 4 arranged on a suspended track 2, with multiple drop plates 401 and multiple side drop plates 402 designed on the hopper 4. These can be combined to form a drop channel or a side drop channel. In the initial stage of unloading, the hopper 4 can unload through the drop channel, causing soil and rocks to accumulate below the hopper 4. When the accumulation reaches a certain level, the drop channel is closed and the side drop channel is opened by changing the drop plates 401 and the side drop plates 402. At this time, the hopper 4 outputs soil and rocks evenly to both sides through the side drop channel, avoiding the accumulation of soil in one place in the carriage, which would cause difficulties in subsequent unloading. This invention solves the problems of single unloading direction, easy loading imbalance, and low unloading efficiency in traditional deep foundation pit earthwork transportation, and improves the intelligence of deep foundation pit earthwork transportation.

[0044] In an embodiment of the invention, the top of the diversion block 404 consists of two symmetrical inclined surfaces, and the bottom has a concave structure. The concave structure at the bottom of the diversion block 404 provides space for the rotation of the drop plate 401. The structural design of the diversion block 404 combines flow guidance and spatial adaptation functions. Its top, composed of two symmetrical inclined surfaces, guides the soil and rocks above into the hopper, ensuring even distribution on both sides and preventing soil accumulation within the hopper, thus ensuring balanced soil and rock distribution during subsequent unloading. The concave structure at the bottom specifically provides rotation space for the drop plate 401, preventing... When the drop plate 401 rotates, it structurally interferes with the diversion block 404, ensuring the smooth operation of the drop plate 401. More importantly, this structural design allows the soil and rocks in the hopper to be supported solely by the enclosure of the drop plate 401 and the side drop plate 402. When either the drop channel or the side drop channel is opened, the corresponding support structure is released, and the unsupported soil and rocks will naturally exit along the opened channel under their own gravity, achieving unloading without additional power. This simplifies the unloading mechanism and ensures the continuity and smoothness of soil and rock output, effectively improving the unloading efficiency of the hopper. The two inclined surfaces at the top of the diversion block 404 do not provide support for the soil and rocks; they only serve a guiding function.

[0045] In an embodiment of the present invention, the auxiliary feeding assembly 5 further includes a base 503 arranged on the top of the steel frame 1. A plurality of fixed frames 504 are arranged on the top of the base 503. A drive plate 505 is rotatably arranged on the inner side wall of the fixed frame 504. The drive plate 505 has an elongated groove 506 on its side wall. A motor 507 and a fixed frame 508 are also arranged on the top of the base 503. A rotating disk 509 is rotatably arranged on the side wall of the fixed frame 508. The motor 507 is connected to the rotating disk 509 via a chain and sprocket assembly. A protruding post 510 is connected to the side wall of the rotating disk 509. The protruding post 510 is movably arranged in the elongated groove 506. A fixed frame 511 is also arranged on the top of the base 503. The fixed frame 511 has a sliding hole from top to bottom. A lifting tube 512 is movably arranged in the sliding hole of the fixed frame 511. A protruding post 513 is connected to the outer circumference of the lifting tube 512. The protruding post 513 is movably arranged in the elongated groove 506. The base 503 provides an installation foundation for each component. When the motor 507 starts, it drives the rotating disk 509 on the fixed frame 2 508 to rotate through the chain and sprocket assembly. The protrusion 510 on the side wall of the rotating disk 509 moves in a circular motion. Since the protrusion 510 is movably placed in the long groove 506 of the drive plate 505, it can drive the drive plate 505 to rotate around the fixed frame 1 504. When the drive plate 505 rotates, its long groove 506 drives the lifting pipe 512 to move up and down along the sliding hole of the fixed frame 3 511 through the protrusion 2 513, thereby realizing the drive of subsequent components such as the pressure rod 501 and the chuck 502, and providing power for pushing and crushing the soil in the hopper 4.

[0046] During the process of the convex post 510 moving in a uniform circular motion with the rotating disk 509, when the convex post 510 moves to a direction close to the fixed frame 504, its cooperation with the drive plate 505 forms a lever structure with the fixed frame 504 as the fulcrum. At this time, the tangent of the first protrusion 510, acting as the power end of the lever, changes the angle between its trajectory and the force direction of the drive plate 505, thus increasing the ratio of the power arm to the resistance arm. Since the linear velocity of the first protrusion 510 remains constant, under the lever principle, the motion of the power end is amplified and transmitted to the other end of the drive plate 505 through the lever, resulting in a significant increase in the rotational angular velocity of the drive plate 505 around the fixed frame 504, achieving rapid downward swing. The rapid downward swing of the drive plate 505, through the cooperation of the long slot 506 and the second protrusion 513, transforms this accelerated motion into linear motion of the lifting tube 512 along the sliding hole of the fixed frame 511, pushing the lifting tube 512 downward rapidly, thereby providing strong impact kinetic energy for the pressure rod 501 and the chuck rod 502, enhancing the pushing and crushing effect on the soil in the hopper.

[0047] Furthermore, a limiting plate 523 is connected to the outer circumference of the lifting pipe 512. A spring 514 is connected to the bottom of the limiting plate 523, and a water storage pipe 515 is connected to the bottom of the spring 514. The bottom of the water storage pipe 515 is connected to the pressure rod 501. This invention, through the design of the auxiliary feeding component 5, when the hopper 4 is feeding material, drives the rotating disk 509 to rotate via the chain and sprocket assembly through the motor 507, further driving the lifting pipe 512 to descend rapidly. The lifting pipe 512, through the spring 514 and the water storage pipe 515, drives the pressure rod 501 to descend rapidly, enabling the pressure rod 501 to... The pressure applied to the soil inside the hopper 4 creates downward pressure, allowing the soil to be quickly discharged through the open drop channel or the open side drop channel along the two inclined surfaces at the top of the diversion block 404. By designing the pressure rod 501 as a frustum structure, the bottom area of ​​the pressure rod 501 is large, allowing it to form a large contact area with the soil inside the hopper 4. This enables the pressure rod to be applied evenly to the soil below, improving the efficiency of soil output and avoiding local pressure concentration that would reduce the thrust effect on the soil. This solves the problem of blockage caused by slow soil output during the feeding process.

[0048] The inner cavity of the water storage pipe 515 is provided with a water storage chamber 516. The outer circumference of the riser pipe 512 is also connected with a pressure block 517. The bottom of the riser pipe 512 is connected to the piercing rod 502. The riser pipe 512 movably passes through the inner cavity of the water storage pipe 515 and extends to the inner cavity of the pressure rod 501. The pressure block 517 is arranged in the water storage chamber 516 and slides with the water storage chamber 516. The piercing rod 502 is movably arranged in the inner cavity of the pressure rod 501. The inner cavity of the riser pipe 512 is provided with a water inlet channel 518. The input end of the water inlet channel 518 is arranged at the top of the riser pipe 512, and the output end of the water inlet channel 518 is arranged at the bottom of the pressure block 517. The top of the riser pipe 512 is connected to an external water injection device through a hose. A groove 519 is provided on the outer circumference of the lifting pipe 512, and a slider 520 is connected to the inner circumference of the pressure rod 501. The lifting pipe 512 slides in cooperation with the slider 520 through the groove 519. The gap between the outer circumference of the lifting pipe 512 and the inner circumference of the pressure rod 501 forms a water spray channel 521. Multiple atomizing nozzles 522 are installed at the bottom of the outer circumference of the water storage pipe 515, and the input end of the atomizing nozzle 522 is connected to the water storage tank 516. The poking rod 502 is arranged below the water spray channel 521, and the top of the poking rod 502 contacts the output end of the water spray channel 521, which can form a sealing effect on the water spray channel 521. When the poking rod 502 moves downward relative to the pressure rod 501, the top of the poking rod 502 separates from the output end of the water spray channel 521, so that the water spray channel 521 is in the open state.

[0049] The present invention also connects the pressure rod 501 and the limiting plate 523 through a spring 514. When the pressure rod 501 encounters significant resistance when pressing down on the soil, exceeding the elastic deformation range of the spring 514, the pressure rod 501 stops pressing down, while the lifting pipe 512 continues to descend and slides relative to the pressure rod 501, causing the piercing rod 502 connected to its bottom to extend out from the inner cavity of the pressure rod 501 to pierce and break up the soil with significant resistance. On the one hand, this avoids the problem of equipment damage caused by continuing to force the pressure rod 501 down when it encounters significant resistance. On the other hand, it can use the piercing rod 502 to pierce and break up the soil with significant resistance, dispersing soil clumps, removing blockages, and allowing the soil to be smoothly output along the falling channel or side falling channel under the continuous thrust of the pressure rod 501.

[0050] This invention also incorporates a water storage pipe 515, into which water is continuously injected via an external water injection device into the water storage chamber 516, filling the chamber with water. The water pressure within the chamber is high, and some water is sprayed out through the atomizing nozzle 522 at the bottom of the outer circumference of the water storage pipe 515, forming an atomized water curtain. This atomized water curtain effectively suppresses dust generated during earthwork unloading, reducing dust pollution to the working environment. Simultaneously, when the pressure rod 501 encounters significant resistance while pressing down on the earthwork, it stops pressing down, while the lifting pipe 512 continues to descend and slides relative to the pressure rod 501, driving its bottom connection... The piercing rod 502 extends from the inner cavity of the pressure rod 501 to pierce and break up the soil with high resistance. During this process, when the lifting pipe 512 descends, the pressure block 517 connected to its outer circumference slides synchronously in the water storage tank 516, squeezing the water in the tank. Furthermore, the piercing rod 502 extends from the inner cavity of the pressure rod 501, so that the water spraying channel 521 between the lifting pipe 512 and the pressure rod 501 is open, causing some water to flow out through the water spraying channel 521 to moisten the soil in the hopper 4, making the clumped soil moist and soft, and making it easier for the piercing rod 502 to penetrate the soil, thereby making it easier to break up the clumps and blockages.

[0051] Working Principle: This embodiment provides an intelligent conveying system for deep foundation pit earthwork based on track suspension. In use, the motor of the drive unit 3 starts, driving the pulley 301 to move along the suspended track 2, transporting the hopper 4 to above the loading point inside the deep foundation pit. The winch 302 then operates, releasing the wire rope. Through the connection between the anti-disengagement hook 303 and the hanging ring 406, the hopper 4 is lowered to the loading position. At this time, the lower plate 401 and the side plate 402 are both in an enclosed state. The frame 403, the lower plate 401, and the side plate 402 together form a closed hopper, beginning to receive earthwork from the deep foundation pit. After loading is completed, the winch 302 retracts the wire rope, lifting the hopper 4. The motor of the drive unit 3 operates again, causing the pulley 301 to move along the circular track. The suspended track 2 rolls, transporting the hopper 4 to above the unloading area; the first cylinder 409 is activated, its output end drives the push-pull frame 410 to move, pushing the two drop plates 401 to rotate around the first shaft 407 to a vertical position via the push-pull rod 408. At this time, the side drop plates 402 remain closed, forming a falling channel between the drop plates 401 and the side drop plates 402. Under the action of gravity, the soil is vertically discharged into the dump truck bed through the falling channel; when a certain amount of soil accumulates at the bottom of the truck bed, the first cylinder 409 is activated to reset the drop plates 401 to a closed position, and then the second cylinder 415 is activated, driving the lifting plate 416 to rise and fall along the slide rail 414. Through the cooperation of the movable groove 417 and the drive column 412, the side drop plates 402 rotate around the second shaft 411 to a vertical position. In the tilted state, the lowering plate 401 remains enclosed, forming a side-falling channel above the lowering plate 401 and the side-falling plate 402. The excavated soil is discharged laterally through this channel, achieving a uniform distribution of soil within the truck bed. During unloading, the auxiliary unloading assembly 5 works synchronously. The motor 507 drives the rotating disk 509 to rotate via a chain and sprocket assembly. The first protrusion 510 on the rotating disk 509 moves within the elongated groove 506 of the drive plate 505, causing the drive plate 505 to rotate around the first fixed frame 504. This, in turn, drives the lifting pipe 512 to reciprocate up and down along the sliding hole of the third fixed frame 511 via the second protrusion 513. When the lifting pipe 512 descends, it drives the pressure rod 501 downwards via the spring 514 and the water storage pipe 515. The pressure rod 501, with its frustum structure... 1. Apply downward pressure to the soil in the hopper 4 to promote the output of the soil along the channel; when the soil blockage is severe and the pressure bar 501 is under great pressure resistance, the spring 514 is compressed to the limit, the lifting pipe 512 continues to descend and slides relative to the pressure bar 501, driving the piercing rod 502 to extend out from the inner cavity of the pressure bar 501 to break up the blocked soil. At the same time, the external water injection equipment injects water into the water storage tank 516 of the water storage pipe 515 through the water inlet channel 518 of the lifting pipe 512. Some of the water forms an atomized water curtain through the atomizing nozzle 522 to suppress dust; when the piercing rod 502 extends and opens the water spray channel 521, the water in the water storage tank 516 flows out through the water spray channel 521 under the pressure of the pressure block 517, moistening the soil and making it easier for the piercing rod 502 to break up the clumps.After unloading, the lower plate 401 and side plate 402 of hopper 4 return to their original positions and close, and the drive device 3 transports hopper 4 back to the loading point to begin the next round of earthmoving operations.
