Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a multi-stage vehicle system that integrates excavation and continuous soil delivery functions. Background Technology

[0002] Traditional construction methods for excavating underground spaces such as basements, parking lots, and subway stations rely on the coordinated operation of excavators and transport machines. However, existing excavators and transport machines are independent devices, leading to the following major problems in practical operation:

[0003] 1. Space Constraints: Sufficient operating space must be reserved in order for the transport equipment to enter and exit the construction site smoothly. This not only occupies valuable construction space, but may also limit the effective implementation of other work activities.

[0004] 2. Low efficiency: When multiple transport vehicles are involved in earthmoving simultaneously, limited site space can easily cause traffic congestion, forcing excavators to stop working and wait for the transport vehicles to finish loading and leave. This downtime severely affects the overall construction progress and reduces work efficiency.

[0005] 3. Increased Costs: The insufficient work efficiency caused by the above reasons extended the project timeline, leading to increased costs related to manpower and machinery rental. Furthermore, frequent work stoppages also increased additional management costs. Utility Model Content

[0006] This utility model addresses the aforementioned problems in the existing technology by proposing a multi-stage vehicle system that integrates digging and continuous soil delivery functions.

[0007] This utility model can be achieved through the following technical solutions:

[0015] The rotating arm is connected to the first hydraulic rod, the rotary excavator head is connected to the rotating arm, the rotating arm is hinged to the first hydraulic rod to form a first rotating joint, and the first hydraulic rod is hinged to the support frame to form a second rotating joint.

[0016] As a further improvement of this utility model, the excavator conveying mechanism includes:

[0017] The first excavator conveyor belt is mounted on the rotating arm and located at the head of the excavator.

[0018] The excavator front conveyor frame and the excavator front conveyor belt are provided, wherein the excavator front conveyor frame is located at the bottom of the support frame and the excavator front conveyor belt is located inside the excavator front conveyor frame.

[0019] The excavator rear conveyor frame and the excavator rear conveyor belt are provided, wherein the excavator rear conveyor frame is located at the rear of the excavator and the excavator rear conveyor belt is located inside the excavator rear conveyor frame.

[0020] A transition conveyor frame and a transition conveyor belt for a dump truck are provided. The transition conveyor frame is mounted on the dump truck, and the transition conveyor belt is disposed within the transition conveyor frame.

[0021] The feed end of the transition conveyor belt of the excavator is located at the bottom of the front conveyor belt of the excavator, and the discharge end of the transition conveyor belt of the excavator is located at the top of the rear conveyor belt of the excavator.

[0022] As a further improvement of this utility model, the bottom of the rear conveying frame of the excavator is provided with a first active rotating component, which is driven by a motor to rotate, thereby driving the rear conveying frame of the excavator to rotate.

[0023] As a further improvement of this utility model, both the first machine conveying mechanism and the second machine conveying mechanism are configured as multi-segment conveyor belt assemblies. Each segment of the conveyor belt assembly includes a machine conveying frame and a machine conveyor belt, with the machine conveyor belt disposed within the machine conveying frame.

[0024] As a further improvement of this utility model, the transition conveyor is also provided with a machine platform transition conveyor belt. The machine platform transition conveyor belt is inclined, with its inlet end located at the bottom of the first machine platform conveyor mechanism and its outlet end located at the top of the second machine platform conveyor mechanism.

[0025] As a further improvement of this utility model, the two adjacent machine platform conveyor frames are connected end to end and are provided with a first follow-up rotating component, while the transition conveyor car and the machine platform conveyor frame are provided with a second active rotating component.

[0026] As a further improvement of this utility model, the earthwork receiving mechanism includes:

[0027] At least one earthwork receiving frame is provided and is used to connect with the telescopic conveyor vehicle; a second follower rotary member is provided between adjacent earthwork receiving frames.

[0028] The earthwork receiving frame is equipped with an earthwork receiving conveyor belt.

[0029] As a further improvement of this utility model, the telescopic conveying mechanism includes:

[0030] The system includes an outer conveying frame, an inner conveying frame, and a telescopic conveyor belt. The outer conveying frame is rotatably connected to the telescopic conveyor vehicle via a third active rotating component. The inner conveying frame is axially movable within the outer conveying frame. The telescopic conveyor belt is located within both the outer and inner conveying frames.

[0031] The telescopic conveyor is also equipped with a telescopic conveyor transition conveyor belt, which is inclined with its inlet end located at the bottom of the earthwork receiving frame and its outlet end located at the top of the outer conveyor frame.

[0032] As a further improvement of this utility model, the surface of the inner conveying frame is provided with a rack, and the rack is arranged along the axial direction of the inner conveying frame.

[0033] The outer conveying frame is equipped with a rotating shaft and a gear. The gear is mounted on the rotating shaft and meshes with the rack. The rotating shaft is driven to rotate by a hydraulic motor, which in turn drives the gear to rotate. As the inner conveying frame moves, the effective conveying length of the telescopic conveyor belt is dynamically adjusted.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The excavator, the transfer conveyor, and the telescopic conveyor form a vehicle system that integrates earthwork excavation, transportation, and unloading. As a result, there is no need to arrange a separate transport machine to carry out earthwork transportation work on the construction site. Only the excavator is used for excavation work on the entire excavation site. This avoids the time waste and low efficiency caused by the separate transport machine entering and leaving the construction site in traditional construction, and greatly improves the overall construction efficiency.

[0036] 2. The drive arm assembly of the excavator has a double joint structure. The connection between the first hydraulic rod and the support frame is the first rotating joint, and the connection between the rotating arm and the first hydraulic rod is the second rotating joint. This double joint structure design gives the drive arm assembly a larger range of motion, especially the vertical extension capability is greatly enhanced, which can realize effective excavation in deeper locations. This is especially important for projects that require deep excavation, such as basements and subway stations. On the other hand, it also improves the flexibility of machine operation and allows for more precise control of the position and posture of the rotary excavator head.

[0037] 3. By using a receiver installed on the excavator and a sensor installed on the rotary excavator head, the current depth of the rotary excavator head is automatically calculated. This real-time depth monitoring system significantly improves the operating accuracy and safety of the excavator, especially in underground space excavation projects, such as the construction of basements and subway stations. Accurate depth monitoring can help avoid over-excavation or under-excavation, ensuring project quality while reducing repair costs.

[0038] 4. The conveyor belt of the excavator can adjust its conveying direction through the first active slewing component, while the conveyor belts of each machine platform of the transition conveyor vehicle can be automatically adjusted through the first follower slewing component. That is, the first active slewing component is responsible for the overall angle adjustment, and the first follower slewing component allows the relative rotation between the conveyor frames of each machine platform. The two work together to improve the flexibility of the entire vehicle system when adjusting its position.

[0039] 5. Both the first and second machine conveying mechanisms are set as multi-segment conveyor belt assemblies. The two adjacent machine conveying frames are connected end to end, and a first follower rotary component is set at the connection between them. This design allows the entire conveying system to move freely within a large range while working, dynamically adjust its posture to adapt to the constantly changing working environment, expand its effective working area, and greatly improve the flexibility of the entire conveying system.

[0040] 6. The telescopic conveyor vehicle, through the design of the telescopic conveying mechanism, can flexibly adjust the effective length of the telescopic conveyor belt according to the actual working conditions. It is suitable for earthmoving tasks of various distances, expands the unloading range of the conveyor body, and can transport to the designated unloading point within a certain range, reducing intermediate transfer links and time costs, and significantly improving the efficiency of earthmoving.

[0041] 7. Each vehicle is equipped with a counterweight mechanism and a gyroscope. Through real-time monitoring by the gyroscope, the control system can accurately grasp the tilt and rotation of each vehicle, thereby enabling fine-tuning of the counterweight position and ensuring that the equipment maintains optimal balance under various working conditions. The automated control system reduces reliance on operators, lowers the possibility of human error, and reduces the workload of operators. It not only ensures the smooth transportation of earthwork but also protects the safety of operators and the construction site. Attached Figure Description

[0055] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0056] like Figure 1-9 As shown, this utility model provides a multi-stage vehicle system integrating digging and continuous soil delivery functions, including:

[0057] The excavator 100 has a rotary excavator head 110 and an excavator conveying mechanism, wherein the rotary excavator head 110 is connected to the excavator conveying mechanism.

[0058] The transition conveyor 200 has a first machine platform conveyor mechanism 210 and a second machine platform conveyor mechanism 220 at its front and rear ends, respectively.

[0059] The telescopic conveyor 300 has an earthwork receiving structure and a telescopic conveying mechanism and is used for earthwork transportation and unloading.

[0060] The excavator conveying mechanism, the first machine platform conveying mechanism 210, the second machine platform conveying mechanism 220, the soil receiving mechanism, and the telescopic conveying mechanism are connected in sequence. The excavator 100 sends the excavated soil into the excavator conveying mechanism through the rotary excavator head 110, and then transports it to the designated unloading point for unloading in sequence through the first machine platform conveying mechanism 210, the second machine platform conveying mechanism 220, and the telescopic conveying mechanism.

[0061] It should be noted that in the existing technology, since the excavator 100 performs excavation work independently, while the earthwork transportation work requires a separate transport vehicle, in the actual construction process, when the excavator 100 is excavating at the construction site, a loading point is set up near the construction site. The excavated earthwork is placed at this loading point, waiting for the transport vehicle to transport it. However, since the excavation area at the construction site is large, when the excavator 100 is excavating at a location far from the loading point, another excavator 100 is needed to transport the earthwork excavated by the first excavator 100 to the loading point. Only then can the transport vehicle transport the earthwork from the loading point outwards, which results in low overall efficiency.

[0062] In addition, multiple transport vehicles are needed for round-trip transportation. Due to the narrow space at the construction site, when multiple transport vehicles participate in earthwork transportation at the same time, traffic congestion is easily caused due to the limited space. This forces the excavators to stop working and wait for the transport vehicles to finish loading and leave. This work stoppage seriously affects the overall construction progress and further reduces work efficiency.

[0063] In contrast, in this embodiment, the excavator 100, the transition conveyor 200, and the telescopic conveyor 300 form a vehicle system that integrates earthwork excavation, transportation, and unloading. As a result, there is no need to arrange a separate transporter for earthwork transportation at the construction site. Only the excavator 100 is used for excavation work at the entire excavation site. This avoids the time waste and inefficiency caused by separate transporters entering and leaving the construction site in traditional construction. There is also no need to arrange another excavator 100 to transport the earthwork to the loading point at the construction site, which greatly improves the overall construction efficiency (about 4-5 times).

[0064] Specifically, such as Figure 2 The following is a description of the excavator 100:

[0065] Preferably, the excavator 100 includes:

[0066] Support frame 120 is installed at the front end of excavator 100;

[0067] The drive arm assembly consists of a rotating arm 130 and a first hydraulic rod 140. The rotary excavator head 110 is connected to the rotating arm 130. The rotating arm 130 and the first hydraulic rod 140 are hinged to form a first rotating joint. The first hydraulic rod 140 is hinged to the support frame 120 to form a second rotating joint.

[0068] This dual-joint structure design gives the drive arm assembly a greater range of motion, especially in terms of vertical extension capability, which is greatly enhanced. It enables effective excavation at deeper locations, which is particularly important for projects such as basements and subway stations that require deep excavation. In actual excavation, the rotary excavator 110 can dig up to 20 meters deep. On the other hand, it also improves the flexibility of machine operation and allows for more precise control of the position and attitude of the rotary excavator 110.

[0069] Preferably, the excavator conveying mechanism includes:

[0070] The first excavator conveyor belt 150 is mounted on the rotating arm 130 and located at the head of the excavator 100;

[0071] The front conveyor frame of the excavator and the front conveyor belt of the excavator 160 are arranged at the bottom of the support frame 120 and the front conveyor belt of the excavator 160 is arranged inside the front conveyor frame of the excavator.

[0072] The excavator rear conveyor frame and the excavator rear conveyor belt 170 are provided. The excavator rear conveyor frame is located at the rear of the excavator 100, and the excavator rear conveyor belt 170 is located inside the excavator rear conveyor frame.

[0073] The excavator transition conveyor frame and the excavator transition conveyor belt 180 are configured. The excavator transition conveyor frame is mounted on the excavator 100, and the excavator transition conveyor belt 180 is mounted inside the excavator transition conveyor frame.

[0074] The feed end of the excavator transition conveyor belt 180 is located at the bottom of the front conveyor belt 160 of the excavator, and the discharge end of the excavator transition conveyor belt 180 is located at the top of the rear conveyor belt 170 of the excavator.

[0075] In actual operation, the earthwork transportation process on the excavator 100 is as follows:

[0076] 1. Initial earthwork transport: After the rotary excavator 110 completes excavation and lifts the earthwork, the earthwork will automatically fall onto the first excavator conveyor belt 150. As the first excavator conveyor belt 150 moves, the earthwork is further transported to the front conveyor belt 160 of the excavator.

[0077] 2. Transition and lifting of earthwork: The front conveyor belt 160 of the excavator delivers the earthwork to its end. At this time, the earthwork naturally falls to the feed end of the transition conveyor belt 180 of the excavator. Since the middle conveyor belt is set at an inclination, it can effectively lift the earthwork upward and overcome the height difference, ensuring that the earthwork smoothly reaches the higher rear conveyor belt 170 of the excavator.

[0078] 3. Final transport and unloading of earthwork: After being lifted by the excavator's transition conveyor belt 180, the earthwork reaches the top of the excavator's rear conveyor belt 170, and is then transported outward by the excavator's rear conveyor belt 170, and finally unloaded onto the transition conveyor 200.

[0079] Among them, several baffles 151 are arranged at intervals on the first excavator conveyor belt 150. The baffles 151 ensure that no matter what angle the rotating arm 130 is in, the soil can be transported along the first conveyor belt without falling off.

[0080] Preferably, the bottom of the rear conveyor frame of the excavator is provided with a first active rotating component 191. The first active rotating component 191 is driven to rotate by a motor, which in turn drives the rear conveyor frame of the excavator to rotate. In other words, the setting of the first active rotating component 191 allows the rear conveyor belt 170 of the excavator to be adjusted in direction according to actual needs, while the excavator 100 itself does not need to rotate or move, thereby better adapting to the layout of different construction sites.

[0081] Preferably, the rotary excavator head 110 has a rotary track 111 on its surface, and a number of digging plates 112 are arranged at intervals on the rotary track 111. The outer edge of the digging plate 112 is set with a toothed structure. The toothed structure of the digging plate 112 can cut into the ground more easily during the rotation of the rotary track 111, reduce digging resistance, improve digging efficiency, and also lift the excavated soil along the rotary track 111 through the digging plate 112 until it finally falls into the first excavator conveyor belt 150.

[0082] The rotary excavator 110 is also equipped with a baffle 113 at its front end. The baffle 113 is designed to prevent soil from falling and ensure that the rotary excavator 110 can smoothly lift the excavated soil upwards. The lower edge of the baffle 113 is designed as an arc surface and bends towards the direction of the rotary excavator 110. This design helps to guide the flow path of the soil.

[0083] In addition, this excavator 100 is also equipped with a real-time depth monitoring system, as detailed below:

[0084] 1. System Composition

[0085] Distance sensor: Installed on the rotary excavator head 110, used to accurately measure the distance between the rotary excavator head 110 and the ground or other reference objects.

[0086] Data transmission module: responsible for wirelessly or wiredly transmitting the data collected by the ranging sensor to the receiver on the vehicle body.

[0087] Receiver: Located inside the vehicle, it receives data from the ranging sensor and converts it into visualized depth information through an internal processing unit.

[0088] Display screen: Located in the control room, it is used to display the current depth of the rotary excavator 110 and other relevant information in real time.

[0089] 2. Arrangement of ranging sensors

[0090] Multi-point ranging: Multiple ranging sensors (e.g., three or more) are installed on the rotary excavator head 110, distributed at different locations, to ensure accurate measurement of depth at different angles. These sensors can be ultrasonic sensors, laser rangefinders, or infrared rangefinders, etc., depending on the application scenario and accuracy requirements.

[0091] 3. Data Processing and Transmission

[0092] Signal processing: Each ranging sensor is equipped with its own microprocessor for preliminary processing of the raw ranging data, such as filtering and calibration.

[0093] Wireless / Wired Communication: Processed data is transmitted to a receiver inside the vehicle via wireless (e.g., Wi-Fi, Bluetooth, Zigbee) or wired (e.g., CAN bus, Ethernet) methods. A suitable communication protocol is selected to ensure the stability and real-time performance of data transmission.

[0094] 4. Receiving and Displaying

[0095] Reception and Decoding: After receiving the ranging data, the receiver inside the vehicle decodes and processes it to calculate the specific depth of the rotary excavator 110.

[0096] Visual Interface: The depth information of the rotary excavator 110 is presented intuitively on the screen in the control room. Various formats, including digital displays, graphical representations (such as analog dashboards), and color coding, can be used to help the operator quickly understand the current working status.

[0097] Workflow

[0098] Initialization: After power-on, all ranging sensors perform self-tests to confirm that they are in good working order; at the same time, the control room screen initializes to prepare for receiving and displaying depth information.

[0099] Real-time monitoring: When the rotary excavator head 110 starts working, each ranging sensor continuously collects depth data and sends it to the receiver via the data transmission module. The receiver processes the received data and updates the depth information displayed on the control room screen in real time.

[0100] Feedback control: The operator adjusts the digging action based on the depth information displayed on the screen to ensure that the operation meets the design requirements.

[0101] This real-time depth monitoring system significantly improves the operational accuracy and safety of the excavator 100, especially in underground space excavation projects such as basement and subway station construction. Precise depth monitoring can help avoid over-excavation or under-excavation, ensuring project quality while reducing repair costs.

[0102] like Figure 3-5 As shown, the description of the transition transport vehicle 200 is as follows:

[0103] The transition conveyor 200 is used to construct a transition bridge between the excavator 100 and the telescopic conveyor 300. It includes a first platform conveyor mechanism 210, a platform transition conveyor belt 230, and a second platform conveyor mechanism 220. The excavator 100 transports soil through the first platform conveyor mechanism 210, the platform transition conveyor belt 230, and the second platform conveyor mechanism 220 in sequence, and then smoothly delivers it to the telescopic conveyor 300. Finally, the telescopic conveyor 300 delivers the soil to the designated unloading point for unloading.

[0104] Preferably, both the first machine conveying mechanism 210 and the second machine conveying mechanism 220 are configured as multi-segment conveyor belt assemblies. Each segment of the conveyor belt assembly includes a machine conveying frame 240 and a machine conveyor belt 250. The machine conveyor belt 250 is installed inside the machine conveying frame 240. Through the continuous operation of the machine conveyor belt 250, the purpose of conveying earthwork is achieved.

[0105] The two adjacent conveyor frames 240 are connected end to end, and a first follower rotary member 241 is provided at the connection between them. The first follower rotary member 241 allows relative rotation between adjacent conveyor sections. A second active rotary member 242 is provided between the transition conveyor 200 and the conveyor frame 240. By driving the second active rotary member 242 to rotate by a motor, the conveyor frame 240 can be rotated, which improves the flexibility of adjustment.

[0106] Therefore, during the excavation process of the external excavator 100, the transition conveyor 200 can move freely within the range of the excavator 100 as the center and the first machine conveyor mechanism 210 as the radius.

[0107] Meanwhile, the telescopic conveyor 300 can also move freely within a range with the transition conveyor 200 as the center and the second machine platform conveyor mechanism 220 as the radius.

[0108] This design allows the entire conveying system to move freely within a large range while in operation, dynamically adjusting its posture to adapt to the ever-changing working environment, thus expanding its effective working area and greatly improving the flexibility of the entire conveying system.

[0109] Preferably, the machine transition conveyor belt 230 is inclined, with its feed end located at the bottom of the first machine conveyor mechanism 210 and its discharge end located at the top of the second machine conveyor mechanism 220. The machine transition conveyor belt 230 is used for the transition conveying of earthwork between the first machine conveyor mechanism 210 and the second machine conveyor mechanism 220.

[0110] It is worth mentioning that in the first conveyor mechanism 210, the height of each section of the conveyor belt 250 decreases gradually from far to near, and in the second conveyor mechanism 220, the height of each section of the conveyor belt 250 decreases gradually from near to far. This design of gradually decreasing height allows the earthwork to be transported smoothly, maintains the continuity of material transmission, and avoids interruptions in the intermediate links.

[0111] It should also be noted that, since the conveyor belt 170 of the excavator can adjust its conveying direction through the first active slewing component 191, and the conveyor belts 250 of each machine are automatically adjusted through the first follower slewing component 241, the first active slewing component 191 is responsible for the overall angle adjustment, and the first follower slewing component 241 allows the relative rotation between the conveyor frames 240 of each machine. The two work together to improve the flexibility of the entire vehicle system when adjusting its position.

[0112] like Figure 6-9 As shown, the description of the telescopic conveyor 300 is as follows:

[0113] Preferably, the earthwork receiving agency includes:

[0114] At least one earthwork receiving frame 310 is provided and is used to connect with the telescopic conveyor 300. A second follower rotary member 311 is provided between adjacent earthwork receiving frames 300, and an earthwork receiving conveyor belt 312 is provided on the earthwork receiving frame 300.

[0115] Preferably, the telescopic conveyor mechanism includes:

[0116] The outer conveyor frame 320, the inner conveyor frame 330, and the telescopic conveyor belt 340 are provided. The outer conveyor frame 320 is rotatably connected to the telescopic conveyor vehicle 300 via a third active rotating member 321. The inner conveyor frame 330 is axially movable and is disposed within the outer conveyor frame 320. The telescopic conveyor belt 340 is located within the outer conveyor frame 320 and the inner conveyor frame 330.

[0117] The effective conveying length of the telescopic conveyor belt 340 can be dynamically adjusted by moving the axis of the inner conveyor frame 330. This means that when the conveying distance needs to be increased or decreased, the working length of the conveyor belt can be easily adjusted by simply stretching or shrinking the conveyor frame accordingly, without having to re-lay or dismantle the conveyor belt. This expands the unloading range of the telescopic conveyor 300, enabling it to transport materials to the designated unloading point within a certain range. This reduces intermediate transfer links and time costs, and significantly improves the efficiency of earthwork transportation.

[0118] The telescopic conveyor mechanism allows for flexible adjustment of the effective length of the conveyor belt according to actual working conditions, making it suitable for earthmoving tasks of various distances. In particular, it provides an effective solution for long-distance unloading needs in underground space excavation projects such as basements, parking lots, and subway stations.

[0119] Preferably, the telescopic structure is designed as follows:

[0120] The inner conveying frame 330 has a rack 331 on its surface, and the rack 331 is arranged along the axial direction of the inner conveying frame 330.

[0121] The outer conveying frame 320 is equipped with a rotating shaft 350 and a gear 351. The gear 351 is mounted on the rotating shaft 350 and meshes with the rack 331. The rotating shaft 350 is driven to rotate by the hydraulic motor 352, which in turn drives the gear 351 to rotate, ultimately realizing the movement of the inner conveying frame 330. This transmission mechanism is compact and efficient, ensuring direct power transmission and fast response.

[0122] It is worth mentioning that the transmission system driven by the hydraulic motor 352 provides efficient and fast power transmission, enabling the inner conveyor frame 330 to complete the extension and retraction action in a short time, thereby improving work efficiency. The matching design of the rack 331 and gear 351, as well as the precise power transmission provided by the hydraulic motor 352, ensures the movement accuracy of the inner conveyor frame 330 and realizes accurate adjustment of the conveyor belt length.

[0123] Preferably, the device also includes fixed plates 353 on both sides of the outer conveyor frame 320. The two ends of the rotating shaft 350 are mounted on the fixed plates 353 through bearing assemblies. The fixed plates 353 ensure that the rotating shaft 350 always rotates in a fixed position, that is, the gear 351 always rotates in its original position. This drives the inner conveyor frame 330 to move. The high-precision bearing assembly ensures the rotational accuracy of the rotating shaft 350, making the meshing between the gear 351 and the rack 331 tighter and smoother. This avoids the problem of inaccurate movement of the inner conveyor frame 330 due to transmission errors, realizes precise adjustment of the conveyor belt length, and also reduces friction and wear between mechanical parts, reduces the need for daily maintenance, extends the service life of the equipment, and reduces the long-term operating cost.

[0124] This stable transmission system reduces safety hazards caused by mechanical failures and ensures the stability and reliability of the entire conveyor frame during adjustment and extension.

[0125] Preferably, the outer conveying frame 320 has an upper space and a lower space, and the inner conveying frame 330 is located in the lower space. That is, the inner conveying frame 330 always moves within the lower space of the outer conveying frame 320 and will not affect the layout of the upper space.

[0126] Furthermore, the telescopic conveyor belt 340 includes an upper conveying section 341 and a lower conveying section 332. The upper conveying section 341 is located in the upper space, and the lower conveying section 332 is located in the inner conveying frame 330. As the inner conveying frame 330 moves axially, the effective conveying length of the lower conveying section 332 is adjusted to adapt to the unloading requirements of different distances.

[0127] In other words, the upper conveying section 341 of the telescopic conveyor belt 340 is located in the upper space of the outer conveying frame 320, and the lower conveying section 332 of the telescopic conveyor belt 340 is located in the lower space of the outer conveying frame 320. In the actual feeding process, the soil is first conveyed along the upper telescopic conveyor belt 340, and then automatically falls onto the lower telescopic conveyor belt 340 for conveying. Therefore, once the effective conveying length of the lower telescopic conveyor belt 340 is adjusted, the soil only needs to be transported to the upper telescopic conveyor belt 340 to automatically complete the feeding and unloading to the designated unloading point.

[0128] Preferably, the telescopic conveyor 300 is provided with a telescopic conveyor transition conveyor belt 360, which is inclined and has its inlet end located at the bottom of the earthwork conveying frame 310 and its outlet end located at the top of the outer conveying frame 320.

[0129] In addition, it should be noted that the excavator 100, the transition conveyor 200, and the telescopic conveyor 300 are all equipped with a counterweight mechanism 400. The counterweight mechanism 400 includes a fixed frame 410, a rotating frame 420, and a drive motor (not shown in the figure). One end of the rotating frame 420 is connected to the fixed frame 410 through a fourth active rotating component 430. The other end of the rotating frame 420 is provided with a counterweight block 440. The drive motor drives the fourth active rotating component 430 to rotate, thereby driving the rotating frame 420 to rotate.

[0130] The counterweight mechanism 400 can be dynamically adjusted according to the actual working conditions to ensure that the vehicle always maintains a good center of gravity position during operation, preventing tilting or instability caused by material transmission. Especially when operating on uneven ground or under high load conditions, the counterweight mechanism 400 can effectively counteract the influence of external torque, improving the stability and safety of the entire system.

[0131] Preferably, the excavator 100, the transition conveyor 200, and the telescopic conveyor 300 are all equipped with gyroscopes (not shown in the figure) in the direction of their center of gravity. The gyroscopes monitor the tilt angle and rotation rate of the vehicle body relative to the horizontal plane in real time and transmit them to the control system. The control system automatically controls the drive motor to adjust the position of the counterweight 440.

[0132] Through real-time monitoring by the gyroscope, the control system can accurately grasp the tilt and rotation of the vehicle body, thereby enabling fine-tuning of the 440° position of the counterweight block. This ensures that the vehicle maintains optimal balance under various working conditions. The automated control system reduces reliance on operators, lowers the possibility of human error, and reduces the workload of operators. It not only ensures the smooth transportation of earthwork but also protects the safety of operators and the construction site.

[0133] To ensure smooth docking of the excavator 100, transition conveyor 200, and telescopic conveyor 300 in different terrains, the rear conveying frame of the excavator, the conveying frame of the machine platform 240, the earth receiving frame 310, and the outer conveying frame 320 are all designed to be vertically rotatable. Specifically:

[0134] The excavator 100 is equipped with an excavator adjustment frame 190. The rear conveying frame of the excavator is connected to the excavator adjustment frame 190 through a first active rotating component 191. The other end of the excavator adjustment frame 190 is hinged to the vehicle body. The excavator 100 is also equipped with a second hydraulic rod 192. The telescopic end of the second hydraulic rod 192 is connected to the excavator adjustment frame 190. As the telescopic end of the second hydraulic rod 192 is lifted, the connection end between the excavator adjustment frame 190 and the rear conveying frame of the excavator can be driven to rotate upward, thereby adjusting the height of the rear conveying frame of the excavator.

[0135] Meanwhile, a third hydraulic rod 193 is provided between the support frame 120 of the excavator 100 and the adjusting frame 190 of the excavator, and the support frame 120 and the adjusting frame 190 of the excavator are hinged together. As the third hydraulic rod 193 moves, it pushes the support frame 120 to rotate, further adjusting the position of the rotary excavator head 110.

[0136] Similarly, the transition conveyor 200 is equipped with a transition conveyor adjustment frame 260, and also with a fourth hydraulic rod 261 and a fifth hydraulic rod 262. The telescopic end of the fourth hydraulic rod 261 is connected to the second machine platform conveying mechanism 220, and the telescopic end of the fifth hydraulic rod 262 is connected to the first machine platform conveying mechanism 210, which are used to adjust the height of the first machine platform conveying mechanism 210 and the second machine platform conveying mechanism 220, respectively.

[0137] Similarly, the telescopic conveyor 300 is equipped with a telescopic conveyor adjustment frame 370, and also with a sixth hydraulic rod 371 and a seventh hydraulic rod 372. The telescopic end of the sixth hydraulic rod 371 is connected to the outer conveyor frame 320, and the telescopic end of the seventh hydraulic rod 372 is connected to the earthwork receiving frame 310, which are used to adjust the height of the outer conveyor frame 320 and the earthwork receiving frame 310, respectively.

[0138] In addition to facilitating smooth docking between the excavator 100, the transition conveyor 200, and the telescopic conveyor 300 in various terrain conditions, it also enables the telescopic conveyor 300 to reach a conveying height of up to 15 meters during actual operation.

[0139] It should also be noted that the excavator 100, the transfer vehicle 200, and the telescopic transport vehicle 300 are all equipped with engines and electric motors. On the way to the construction site, the engine is used as the power system, and after arriving at the construction site, the electric motor can be used as the power system to save costs.

[0140] Furthermore, the vehicle system provided in this embodiment can be used not only for the excavation and transportation of earthwork (soil, sand, and stones), but also for the transportation of concrete, thus having a wider range of applications.
