Description

Technical Field

[0001] This application relates to the field of bulk material collection and disposal technology, and in particular to an automated system and method for collecting bulk materials left behind by timber transport vehicles. Background Technology

[0002] In timber logistics transportation, especially in port transshipment and yard transfer, after unloading, the loading docks of transport vehicles often retain a large amount of loose materials such as bark and wood chips. Currently, the cleaning of such loose materials mainly relies on manual labor, with workers using brooms, shovels, and other tools to sweep at fixed locations. To improve cleaning efficiency, some operations have introduced mechanical cleaning equipment, such as rotating brush rollers combined with conveyor belts or screw conveyors, to automatically sweep and collect materials from the vehicle loading docks at dedicated workstations.

[0003] However, these mechanical cleaning devices still have some shortcomings in practical applications: First, although the cleaning action is completed by machinery, operators are still required in the stages of equipment positioning, start-stop control, and residual material handling, resulting in limited improvement in overall operational efficiency and the problem of queuing and congestion of transport vehicles has not been fundamentally alleviated; Second, the open dust generated during the cleaning process spreads directly into the surrounding atmosphere, affecting the environmental quality of the port and storage yard, which does not meet the requirements of modern green ports and environmentally friendly operations. Summary of the Invention

[0004] To address the aforementioned problems, this application provides an automated system and method for collecting loose materials left behind by timber transport vehicles.

[0005] On the one hand, the automated collection system for loose materials left behind by timber transport vehicles provided in this application adopts the following technical solution: An automated collection system for loose timber left behind by timber transport vehicles includes a working channel module. The working channel module has a passageway for transport vehicles, with air outlets and collection inlets on opposite side walls of the channel. When a transport vehicle passes through the channel, its cargo platform is positioned between the air outlets and the collection inlets. A blowing module is installed at the air outlets to deliver directional airflow into the channel, blowing loose timber left behind on the vehicle's cargo platform towards the collection inlets. A collection and separation module is installed at the collection inlets to receive the loose timber blown in and separate the solid material from the dust-laden airflow. The system also includes an intelligent control module electrically connected to both the blowing module and the collection and separation module, used to automatically control the start, stop, and coordinated operation of these modules based on vehicle passage signals.

[0006] By adopting the above technical solution, during operation, after the transport vehicle enters the working channel module, the intelligent control module automatically identifies the vehicle and activates each actuator. The high-speed airflow generated by the purging module is blown out directionally through the air outlet and crosses the vehicle's cargo platform bearing surface, blowing the remaining loose materials such as bark and sawdust to the collection port on the opposite side. These materials then enter the collection and separation module for solid-gas separation. Heavier solid materials settle due to gravity and inertia, while the dust-laden gas is filtered and purified. The transport vehicle can automatically complete the cleaning of loose materials while passing through the working channel, without needing to stop and wait, significantly improving the logistics turnover efficiency in ports, storage yards, and other scenarios. At the same time, the fully unmanned operation reduces labor costs and safety risks.

[0007] Optionally, a conveying module is provided below the collection and separation module. The conveying module is used to receive the solid materials separated by the collection and separation module and convey them to a preset collection position. The conveying module is also electrically connected to the intelligent control module.

[0008] By adopting the above technical solution, continuous automatic collection and conveying of solid materials is achieved, avoiding the accumulation of materials at the bottom of the collection box and ensuring the system's ability to operate continuously for a long time.

[0009] Optionally, the purging module includes a centrifugal fan and an adjustable blower mechanism. The air outlet of the centrifugal fan and the air inlet of the adjustable blower mechanism are connected by an air supply pipe. The adjustable blower mechanism is located on the side of the channel near the air outlet, and the air outlet of the adjustable blower mechanism is oriented towards the collection port. The pitch angle and horizontal angle of the air outlet of the adjustable blower mechanism are adjustable.

[0010] By adopting the above technical solution, a stable high-pressure air source is provided by a centrifugal fan, and the blowing direction can be flexibly adjusted through an adjustable blowing mechanism, which can accurately cover the cargo platform surface of different vehicle models, improving blowing efficiency and adaptability.

[0011] Optionally, the adjustable blower mechanism includes a blower bracket, on which a rotary bearing and a drive motor for driving the rotary bearing to rotate horizontally are provided. A mounting base is provided on the rotary bearing, and a mounting frame and an electric cylinder for driving the mounting frame to rotate in a vertical plane are provided on the mounting base. The bottom end of the mounting frame is rotatably connected to the mounting base, and the top end is provided with a blower. The air inlet end of the blower is connected to an air supply pipe, and the air outlet end faces the vehicle cargo platform bearing surface.

[0012] By adopting the above technical solution, the blower can be adjusted in two dimensions in the horizontal and vertical directions through the coordinated action of the drive motor and the electric cylinder. It has a compact structure, reliable operation, and can automatically adapt to vehicles with different platform heights and positions.

[0013] Optionally, the air outlet of the blower is narrowed to a flat opening.

[0014] By adopting the above technical solution, the blower duct shrinks from a large cross-section to a flat opening from the air inlet to the air outlet. This shrinking structure, which changes from round to flat, can effectively improve the airflow speed and concentration at the air outlet, thereby generating a stronger blowing force and ensuring that the loose material is completely blown away from the platform.

[0015] Optionally, the collection and separation module includes a collection box with a feed inlet on the top side of the collection box, the feed inlet being sealed to the collection port, a discharge port at the bottom of the collection box, a conveying module located below the discharge port, a dust collector above the collection box, the air inlet of the dust collector being connected to the top of the collection box, and the air outlet of the dust collector being connected to the air inlet of a centrifugal fan through a suction pipe.

[0016] By adopting the above technical solution, a closed airflow circulation system was constructed. The air output from the centrifugal fan is used for purging, and the return air is filtered by the dust collector and then re-enters the centrifugal fan, thus avoiding the discharge of dust-laden air and realizing environmentally friendly and pollution-free circulation operation.

[0017] Optionally, the collection and separation module further includes a backflushing device for cleaning the dust collector filter element.

[0018] By adopting the above technical solution, the backflush machine can automatically spray high-pressure airflow onto the filter element at regular intervals or according to the pressure difference to remove dust adhering to the surface of the filter element, ensuring long-term efficient operation of the dust collector and reducing the frequency of manual maintenance.

[0019] Optionally, the conveying module is configured as a belt conveyor.

[0020] By adopting the above technical solutions, the belt conveyor has a simple structure and stable operation, and can reliably transport the separated solid materials to the designated collection point, coordinating with other modules of the system.

[0021] Optionally, the intelligent control module includes a vehicle detection sensor, a height sensor, a PLC controller, and a human-machine interface. The vehicle detection sensor is used to detect the approaching vehicle and trigger the system to start. The height sensor is used to detect the height of the vehicle's cargo platform and feed the signal back to the PLC controller to adjust the blowing angle of the blowing module. The human-machine interface is used for touch screen operation.

[0022] By adopting the above technical solution, the system can automatically identify and start the incoming vehicle, and automatically adjust the blowing angle according to the height of the platform. Operators can set parameters and monitor the status through the human-machine interface, which improves the intelligence and ease of use of the system.

[0023] On the other hand, this application also provides a method for collecting leftover materials using the aforementioned automated collection system for timber transport vehicles, comprising the following steps: S1: Drive the transport vehicle through the channel of the operation channel module so that the vehicle's cargo platform is located between the air outlet and the collection port; S2: The intelligent control module automatically detects the incoming vehicle signal, starts the purging module, and delivers directional airflow into the channel through the air outlet to blow the residual loose material on the platform towards the collection port; S3: The bulk material blown in is collected through the collection port, and the solid material and dust-laden airflow are separated by the collection and separation module. S4: Filter the separated dust-laden airflow and transport the separated solid material to the preset collection location via the conveying module.

[0024] This application includes at least one of the following beneficial technical effects: 1. By constructing a closed-loop airflow system, unmanned and low-emission bulk material cleaning operations are achieved while vehicles are in motion, which significantly improves the logistics turnover efficiency in ports, storage yards and other scenarios, while eliminating dust spillage and meeting green environmental protection requirements. 2. By setting an adjustable blower mechanism and a multi-sensor fusion intelligent control system, it can automatically identify the platform height and passage speed of different vehicle models, and adjust the blowing angle and air volume in real time, which has a wide range of adaptability and stable cleaning effect; 3. By combining the dust collector and the back-flushing device in the collection and separation module, the effective separation of solid materials and dust-laden airflow and the automatic cleaning of the filter element are achieved, ensuring the reliability of the system for long-term continuous operation and the convenience of maintenance.

[0028] To make the objectives, features, and advantages of this patent more apparent and understandable, the technical solutions of this patent will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this patent, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] Example 1 Embodiment 1 of this application discloses an automated collection system for loose materials left behind by timber transport vehicles.

[0031] Reference Figure 1 An automated collection system for loose timber left behind by timber transport vehicles includes a working channel module 1, a blowing module 2, a collection and separation module 3, a conveying module 4, and an intelligent control module. The intelligent control module is electrically connected to the blowing module 2, the collection and separation module 3, and the conveying module 4. During operation, after the transport vehicle 5 enters the working channel module 1, the intelligent control module automatically identifies the vehicle and activates each actuator. The high-speed directional airflow generated by the blowing module 2 crosses the vehicle's cargo platform, blowing the loose materials such as bark and sawdust to the collection and separation module 3 on the opposite side for solid-gas separation. Heavier solid materials settle due to gravity and inertia and are transported out in real time via the conveying module 4. The dust-laden gas is filtered and purified, and the clean air returns to the blowing module 2 to form a closed loop. The entire cleaning process is completed automatically while the vehicle is in normal passage without stopping or slowing down, exhibiting significant technical advantages such as high operating efficiency, no dust spillage, and no need for manual intervention.

[0032] Reference Figure 1The working passage module 1 includes an inverted U-shaped steel structure frame 11, which is enclosed by steel plates on the outside. Inside the frame 11, a passage 12 is formed for transport vehicles 5 to pass through. Air outlets 13 and collection ports 14 are respectively opened on the two vertical side walls inside the passage 12. The lower edges of the air outlets 13 and collection ports 14 are designed to ensure that when various common timber transport vehicles 5, such as flatbed trailers and skeleton trucks, pass through, their loading platforms are precisely located between the airflow cross-sections of the air outlets 13 and collection ports 14.

[0033] Reference Figure 1 The purging module 2 includes a centrifugal fan 21, an air supply duct 22, and an adjustable blower mechanism 23. The centrifugal fan 21 is installed inside the frame 11 on the side near the air outlet 13, and the adjustable blower mechanism 23 is located inside the channel 12 on the side near the air outlet 13. The centrifugal fan 21 and the adjustable blower mechanism 23 are connected by the air supply duct 22, which passes through the air outlet 13.

[0034] Reference Figure 1 and Figure 2 The adjustable blower mechanism 23 includes a blower bracket 231, a rotary bearing 232, a drive motor 233, a mounting base 234, a mounting frame 235, a blower tube 236, and an electric cylinder 237. The blower bracket 231 is located inside the channel 12 near the air outlet 13 and can be welded or bolted to the foundation of the channel 12. The rotary bearing 232 and the drive motor 233 are both mounted on the top of the blower bracket 231. The rotary bearing 232 is vertically axially positioned. The drive motor 233's power is reduced and steered via a reducer. The reducer's output end is a worm gear, which meshes with the gear ring of the rotary bearing to drive the rotary bearing 232 to rotate in the horizontal plane. The mounting base 234 is bolted to the top surface of the rotary bearing 232. The bottom end of the mounting frame 235 is hinged to the mounting base 234, and the top end is fixedly connected to the blower tube 236. One end of the electric cylinder 237 is hinged to the mounting base 234, and the other end of the telescopic shaft is hinged to the mounting bracket 235. When the electric cylinder 237 extends or retracts, it can push the mounting bracket 235 to swing around the bottom pivot in a vertical plane, thereby adjusting the pitch angle of the blower 236. The air inlet of the blower 236 is connected to the air supply duct 22, which is a flexible hose to accommodate the movement of the blower 236. The air outlet of the blower 236 faces the collection port 14. In addition, the air outlet of the blower 236 narrows into a flat opening. This transitional structure from round to flat helps to improve the airflow velocity and concentration at the outlet, thereby generating a stronger blowing force.

[0035] Reference Figure 1 and Figure 3The collection and separation module 3 includes a housing 31, a collection box 32, a dust collector 33, a back-blowing device 34, and a suction duct 35. The frame 11 has a space to accommodate the housing 31 on the side near the collection port 14. The collection box 32, dust collector 33, and back-blowing device 34 are all located inside the housing 31. The collection box 32 is fixedly connected to the lower end of the housing 31, and the dust collector 33 is fixedly connected to the upper end of the housing 31. A feed inlet 321 is opened on the top of the side wall of the collection box 32 facing the channel 12. A corresponding opening is made on the housing 31 for the feed inlet 321 of the collection box 32. The feed inlet 321 of the collection box 32 is sealed to the collection port 14 on the side wall of the channel 12 via a flange and a gasket. The bottom of the collection box 32 is cone-shaped and has a discharge port 322. The conveying module 4 is located directly below the discharge port 322. The top of the collection box 32 has an opening and is connected to the air inlet of the dust collector 33 through a pipe. The dust collector 33 is usually a cartridge or bag filter dust collector, which is equipped with a high-efficiency filter component inside.

[0036] Reference Figure 3 The clean air chamber outlet of the dust collector 33 is connected to the air inlet of the centrifugal fan 21 via the suction pipe 35, thus forming a closed airflow circulation system. The dust-laden airflow after purging enters the dust collector 33 for purification through the collection box 32. The clean air is then drawn back into the centrifugal fan 21 through the suction pipe 35 and pressurized before being output. There is no dust-laden gas discharged throughout the process, achieving a clean and environmentally friendly cyclic purging operation. In addition, the suction pipe 35 is laid out along the inside of the frame 11 of the working channel module 1, making full use of the steel space of the frame 11 for concealed pipe routing. This effectively protects the pipes from external impacts and makes the overall equipment look simple and compact, reducing the floor space occupied.

[0037] Reference Figure 3 The backflush unit 34 is installed on the dust collector 33. The backflush unit 34 includes a pulse valve and a compressed air tank. It can periodically spray high-pressure pulse airflow into the filter element of the dust collector 33 to remove dust adhering to the outer surface of the filter element and ensure filtration efficiency.

[0038] Reference Figure 3 The conveying module 4 can be configured as a belt conveyor to transport the solid material falling from the discharge port 322 of the collection box 32 to the preset collection position.

[0039] Reference Figure 1 and Figure 4The intelligent control module is the core of the entire system, which includes a PLC controller, a human-machine interface, vehicle detection sensors, a height sensor, and a vehicle speed sensor. The human-machine interface is used for touch screen operation; the vehicle detection sensor is installed in front of the entrance of channel 12 and can be set as a proximity switch or photoelectric sensor to detect the approaching vehicle and trigger the system to start; the height sensor is installed on the top or side of channel 12 and can be set as a laser rangefinder or ultrasonic sensor to measure the actual height of the vehicle platform and feed the signal back to the PLC controller to adjust the blowing angle of the blowing module 2; the vehicle speed sensor is installed at the entrance of channel 12 and can be set as a radar speedometer to detect the real-time speed of the entering vehicle and feed the signal back to the PLC controller to control the air volume of the blowing module 2; the vehicle speed sensor can sense the actual speed of the vehicle passing through channel 12 in real time and transmit the speed signal to the PLC controller in real time. The PLC controller can automatically adjust the output frequency of the variable frequency mechanism of the centrifugal fan 21 so that the blowing air volume and wind speed are dynamically matched with the vehicle passing speed, ensuring that a uniform cleaning effect can be obtained at different vehicle speeds, and ensuring the consistency and reliability of each bulk material cleaning operation.

[0040] The implementation principle of Embodiment 1 of this application is as follows: When the transport vehicle 5 drives towards the channel 12, the vehicle detection sensor triggers a signal to the PLC controller, waking the system from standby mode. The centrifugal fan 21 starts operating, generating a strong blowing airflow at the outlet of the blower 236, while a negative pressure suction is formed at the top of the collection box 32. After the height sensor detects the height of the vehicle's cargo platform, the PLC controller instructs the drive motor 233 and the electric cylinder 237 to adjust the blower 236 to a preset optimized position. As the vehicle passes through the channel 12, the vehicle speed sensor detects the real-time speed of the vehicle, and the PLC controller instructs the frequency converter of the centrifugal fan 21 to adjust the outlet speed and airflow of the centrifugal fan 21.

[0041] A directional airflow blows all loose material on the platform towards the collection port 14. Larger, heavier solid materials, such as bark and sawdust, settle after impacting the box wall due to inertia, falling into the collection box 32 and being discharged from the discharge port 322. Fine dust and light debris are drawn into the dust collector 33 and captured by the filter element under the negative pressure at the top of the collection box 32. Clean air is drawn in by the centrifugal fan 21 and circulated for purging. The solid material falling from the discharge port 322 and the dust cleaned up by the back-blowing device 34 are all transported away in real time by the belt conveyor below.

[0042] After the vehicle has completely driven away, the collection and cleaning of the loose materials left on the loading platform is also completed automatically. The system automatically shuts down and resets after a delay, waiting for the next vehicle.

[0043] Based on the principles of pneumatic conveying and inertial settling, this system uses intelligently controlled directional high-speed airflow to blow up and collect residues on the vehicle's cargo platform, and completes solid-gas separation within a closed-loop system, achieving non-stop, unmanned, and low-emission bulk material cleaning operations.

[0044] Example 2 A method for collecting leftover bulk materials using the automated collection system for timber transport vehicles described in Example 1 specifically includes the following steps: S1: Drive the transport vehicle 5 through the channel 12 of the operation channel module 1, so that the vehicle's cargo platform is located between the air outlet 13 and the collection port 14. S2: The intelligent control module automatically detects the incoming vehicle signal, starts the blowing module 2, and delivers directional airflow into the channel 12 through the air outlet 13, blowing the residual loose material on the platform to the collection port 14; S3: The bulk material blown in is received through the collection port 14, and the solid material and dust-laden airflow are separated by the collection and separation module 3. S4: The separated dust-laden airflow is filtered, and the filtered clean air is used as the air source for the purging module 2. S5: The separated solid material is transported to the preset collection position via the conveying module 4.

[0045] The above method is completed automatically and continuously during vehicle operation without stopping. The entire process is coordinated by the intelligent control module, which achieves unmanned and highly efficient bulk material cleaning operation.

[0046] The above description of the disclosed embodiments enables those skilled in the art to implement or use this patent. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this patent. Therefore, this patent is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
