Description

Technical Field

[0001] This invention belongs to the field of mineral transportation, specifically relating to a mineral transport vehicle and an automatic loading and unloading system for rail transport in mines. Background Technology

[0002] Currently, in the process of mining rail transport, the loading and unloading of ore buckets in ore transport vehicles largely relies on manual labor, resulting in high labor intensity, low efficiency, and high safety risks. Traditional loading devices are usually semi-automated, such as using fixed chutes or manual operation to load the ore buckets. Simultaneously, unloading operations mostly depend on manually pushing the ore buckets to discharge the material. The entire loading, transport, and unloading process requires significant manual intervention, heavily relying on the strength and experience of the operators, and is prone to considerable errors. Furthermore, workers are exposed to long-term ore dust pollution, which harms their health. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a ore transport vehicle to solve the problem of loading and unloading difficulties caused by the need for manual operation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a ore transport vehicle, including a truck head and a plurality of ore buckets sequentially connected behind the truck head. Each ore bucket includes: a bucket body with an inlet at its top and an outlet on one side; the bucket body includes a bottom plate, first side plates located on both sides of the outlet, and a second side plate opposite to the outlet; the second side plate is connected to the two first side plates on both sides respectively, forming the bucket body together with the bottom plate; and a baffle assembly, including a baffle plate, a transmission shaft fixed to the top of the baffle plate, and a motor located outside the bucket body. The baffle plate is rotatably connected to the two first side plates via the transmission shaft, and the motor drives the baffle plate to rotate via the transmission shaft connected to it. The device includes an opening and closing discharge port; and a pushing assembly, located within the hopper, for pushing ore out of the discharge port when the baffle plate opens the discharge port. The pushing assembly includes a pushing plate and a pushing / pulling member. The pushing plate includes a pushing bottom plate and a pushing side plate rotatably connected via a pushing shaft. The pushing / pulling member is connected between the transmission shaft and the pushing shaft. The pushing plate has a transport position and a pushing position. When the pushing plate is in the transport position, the pushing bottom plate horizontally covers the bottom plate, and the pushing side plate vertically covers the second side plate. When the pushing plate is in the pushing position, the pushing bottom plate and the pushing side plate are inclined towards the discharge port. The pushing / pulling member moves the pushing shaft to switch the pushing plate between the transport position and the pushing position. This technical solution has the following technical effects: This invention designs a ore hopper with a baffle assembly on one side that has an openable / closable discharge port, and an internal pushing assembly. This allows the pushing assembly with the closed discharge port and the pushing plate in the transport position to work together to hold the ore during loading and transportation. When the pushing plate is in the transport position, the pushing bottom plate horizontally covers the bottom plate, and the pushing side plate vertically covers the second side plate. The space occupied by these components within the hopper is minimal, thus having little impact on the ore loading capacity and maximizing the ore loading. During unloading, the motor can drive the baffle plate to rotate and open the discharge port. Driven by the push-pull components, the pusher shaft at the feed inlet can move the pusher plate to the pusher position, causing the horizontally extending pusher bottom plate and the vertically extending pusher side plate to tilt towards the discharge port. This assists in the sliding of all the ore towards the discharge port, achieving automatic unloading of the ore hopper. Without manual assistance from staff, the ore in the hopper can be automatically unloaded, avoiding long-term pollution of ore dust to staff and ensuring their health. At the same time, the tilted pusher bottom plate and pusher side plate can also prevent the ore from accumulating at the angle between the pusher bottom plate and the pusher side plate, ensuring complete unloading.

[0005] In the aforementioned type of ore transport vehicle, a limiting shaft is provided on the side of the pusher base plate near the discharge port. The pusher base plate is rotatably connected to two first side plates via the limiting shaft. When the pusher shaft moves one side of the pusher base plate, the side near the discharge port always rotates around the limiting shaft. This allows the slope of the pusher base plate to be controlled according to the different viscosities of the ore, thereby ensuring that all the ore can be unloaded. It also prevents the height of the pusher base plate near the discharge port from changing, which could create a large gap and thus prevent the ore from accumulating in that gap.

[0006] In the aforementioned type of ore transport vehicle, the push-pull component is an electric push rod. The electric push rod extends and retracts to move the pushing shaft, thereby switching the pushing plate between the transport position and the pushing position. Because all the ore in the hopper is on the pushing bottom plate, the push-pull component experiences a significant load when pulling the pushing shaft on one side of the pushing bottom plate. Using an electric push rod as the push-pull component allows for stable pulling of the pushing shaft under high loads, extending the service life of the push-pull component. Furthermore, the high precision of the electric push rod ensures accurate control of the slope of the pushing bottom plate, reducing the difficulty of unloading ore.

[0007] In the aforementioned type of ore transport vehicle, the push-pull component is a pull chain with one end wound around a drive shaft. The drive shaft rotates to extend and retract the pull chain, thereby moving a pusher shaft and switching the pusher plate between a transport position and a pusher position. By rotating the drive shaft to extend and retract the pull chain, the length of the pull chain between the drive shaft and the pusher shaft is changed, thus moving the pusher shaft and allowing the pusher plate to switch between the transport and pusher positions. The pull chain structure is simple, reducing the production cost of the push-pull component.

[0008] In the aforementioned type of ore transport vehicle, two push-pull components are provided, located on both sides of the push plate and connected to both ends of the push shaft. Because the push plate is large and prone to deformation due to uneven force, providing two push-pull components on both sides of the push plate ensures uniform force distribution on the push plate.

[0009] In the aforementioned type of ore transport vehicle, an electronically controlled lock is provided on the first side panel. The electronically controlled lock is configured to lock the pushing side panel in the transport position. The electronically controlled lock is locked to the pushing side panel to secure it in the transport position, ensuring that the pushing side panel remains stably in the transport position during ore bucket transport, preventing the pushing side panel from shaking, and thus avoiding noise caused by the shaking of the pushing side panel during transport.

[0010] In the aforementioned type of ore transport vehicle, the pusher side plate is provided with an insertion hole facing the first side plate. The locking pin of the electric lock is horizontally inserted into the insertion hole to lock the pusher side plate in the transport position. The structure is simple and reliable.

[0011] This invention also provides an automated loading and unloading system for rail-based mining transportation, including the aforementioned ore transport vehicle, with a drive module on the vehicle head, and further including: a track, along which the ore transport vehicle can move between the loading area and the unloading area; an ore discharge machine, located in the loading area and on one side of the track, with multiple parking points on one side of the ore discharge machine, so that when the vehicle head stops sequentially at the multiple parking points, each ore bucket is sequentially parked on one side of the ore discharge machine; a first video detection device, located in the loading area on the other side of the track and opposite to the ore discharge machine, to collect image information of the ore buckets opposite to the ore discharge machine; and a control module, configured to determine whether the ore buckets are aligned with the ore discharge machine based on the ore bucket image information collected by the first video detection device, and to adjust the position of the corresponding ore buckets through the drive module. When the ore buckets passing by the ore discharge machine are aligned with the ore discharge machine, the control module controls the ore discharge machine to work to dump ore into the corresponding ore buckets. By setting up tracks, ore transport vehicles, control modules, ore discharge machines, and a first video detection device, the fully automated loading, transportation, and unloading of ore is achieved. The entire loading and unloading process does not require on-site personnel participation, which avoids large errors and also prevents workers from being exposed to ore dust pollution in the mine for a long time, thus ensuring the health of the workers. Because the various ore buckets are connected by chains, and the ore buckets are connected to the tractor, the distance between the ore buckets and between the ore buckets and the tractor may change during the stopping process. This can lead to a problem where the ore bucket and the ore feeder cannot be precisely aligned when any ore bucket is placed between them. As a result, some ore may spill out when the ore feeder pours it into the placed ore bucket, leading to poor loading efficiency. The first video detection device can collect image information of the ore buckets opposite the ore feeder. The control module can determine whether the ore buckets are aligned with the ore feeder based on the image information collected by the first video detection device, and adjust the position of the corresponding ore buckets through the drive module to ensure precise alignment between the ore buckets and the ore feeder. This ensures accurate alignment and loading of each ore bucket with the ore feeder, improving loading efficiency.

[0012] The aforementioned automated loading and unloading system for rail-guided mining also includes a second video detection device. This device is located in the unloading area to collect image information of all ore buckets within the area. The control module is configured to determine whether all ore buckets have entered the unloading area based on the image information collected by the second video detection device, and adjusts the position of the ore buckets via a drive module. When all ore buckets enter the unloading area, the control module controls the ore buckets to push out all the ore. This ensures that all ore buckets accurately unload the ore into the designated storage area, achieving fully automated and precise unloading.

[0013] In the aforementioned automated loading and unloading system for rail-guided mining, a weight detection device connected to the control module is installed on the bottom plate. When the pushing component is in the transport position, the weight detection device detects the weight of the material above it through the pushing bottom plate. During loading of the hopper, the control module can detect the weight of the ore in the hopper using the weight detection device. When the weight of the ore in the hopper reaches a set value, the module controls the unloading machine to stop dumping ore, preventing overflow. During unloading of the hopper, the control module can detect the remaining ore in the hopper using the weight detection device. If the ore in the hopper fails to leave the hopper during the initial push due to high viscosity or other reasons, the module controls the pushing component to switch from the transport position to the pushing position again to push the remaining ore in the hopper a second time, ensuring that the hopper can be completely unloaded with good unloading efficiency.

Detailed Implementation

[0017] This invention proposes a ore transport vehicle, comprising a truck head and multiple ore buckets sequentially connected behind the truck head. Each ore bucket includes: a bucket body with a feed inlet at its top and a discharge outlet on one side; the bucket body includes a bottom plate, first side plates located on either side of the discharge outlet, and a second side plate opposite to the discharge outlet; the second side plate is connected to the two first side plates on both sides, forming the bucket body together with the bottom plate; and a baffle assembly, including a baffle plate, a drive shaft fixed to the top of the baffle plate, and a motor located outside the bucket body. The baffle plate is rotatably connected to the two first side plates via the drive shaft, and the motor drives the baffle plate to rotate via the drive shaft to open and close the discharge outlet; and The material pushing assembly, located inside the hopper, is used to push the ore inside the hopper out of the discharge port when the baffle plate opens the discharge port. The material pushing assembly includes a material pushing plate and a push-pull component. The material pushing plate includes a material pushing bottom plate and a material pushing side plate rotatably connected by a material pushing shaft. The push-pull component is connected between the transmission shaft and the material pushing shaft. The material pushing plate has a transport position and a material pushing position. When the material pushing plate is in the transport position, the material pushing bottom plate horizontally covers the bottom plate, and the material pushing side plate vertically covers the second side plate. When the material pushing plate is in the material pushing position, the material pushing bottom plate and the material pushing side plate are inclined towards the discharge port. The push-pull component drives the material pushing shaft to move, so that the material pushing plate switches between the transport position and the material pushing position. This invention designs a ore hopper with a baffle assembly on one side that has an openable / closable discharge port, and an internal pushing assembly. This allows the pushing assembly with the closed discharge port and the pushing plate in the transport position to work together to hold the ore during loading and transportation. When the pushing plate is in the transport position, the pushing bottom plate horizontally covers the bottom plate, and the pushing side plate vertically covers the second side plate. The space occupied by these components within the hopper is minimal, thus having little impact on the ore loading capacity and maximizing the ore loading. During unloading, the motor can drive the baffle plate to rotate and open the discharge port. Driven by the push-pull components, the pusher shaft at the feed inlet can move the pusher plate to the pusher position, causing the horizontally extending pusher bottom plate and the vertically extending pusher side plate to tilt towards the discharge port. This assists in the sliding of all the ore towards the discharge port, achieving automatic unloading of the ore hopper. Without manual assistance from staff, the ore in the hopper can be automatically unloaded, avoiding long-term pollution of ore dust to staff and ensuring their health. At the same time, the tilted pusher bottom plate and pusher side plate can also prevent the ore from accumulating at the angle between the pusher bottom plate and the pusher side plate, ensuring complete unloading.

[0023] Example 1:

[0024] A type of ore transport vehicle, such as Figures 1 to 4 As shown, the system includes a truck head 600 and multiple ore buckets connected in sequence and positioned behind the truck head 600. Each ore bucket includes a bucket body 100, a baffle assembly 200, and a pusher assembly 300. The top of the bucket body 100 has a feed inlet 140, and one side of the bucket body 100 has a discharge outlet 150. Figure 2 As shown, the bucket body 100 includes a bottom plate 110, first side plates 120 located on both sides of the discharge port 150, and a second side plate 130 opposite to the discharge port 150. The two sides of the second side plate 130 are respectively connected to the two first side plates 120. The first side plates 120 and the second side plates 130 are fixed to the edge of the bottom plate 110 so as to form the bucket body 100 together with the bottom plate 110. The baffle assembly 200 includes a baffle plate 210, a transmission shaft 220, and a motor 230. The transmission shaft 220 is fixed to the top of the baffle plate 210 to move in conjunction with the baffle plate 210, so that the upper part of the baffle plate 210 is rotatably connected to the two first side plates 120 through the transmission shaft 220. The motor 230 is located outside the bucket body 100, and the output shaft of the motor 230 is connected to the transmission shaft 220 to move in conjunction with the transmission shaft 220. When the output shaft of the motor 230 rotates, the transmission shaft 220 drives the baffle plate 210 to rotate together. The baffle plate 210 swings around the transmission shaft 220 to open or close the discharge port 150.

[0025] The pushing assembly 300 is disposed inside the bucket body 100 and is used to push the ore inside the bucket body 100 out of the discharge port 150 when the baffle plate 210 opens the discharge port 150. The pushing assembly 300 includes a pushing plate 310 and a push-pull member. The pushing plate 310 includes a pushing bottom plate 311 and a pushing side plate 312. The bottom of the pushing side plate 312 is rotatably connected to the side of the pushing bottom plate 311 away from the discharge port 150 through a horizontally extending pushing shaft 313. The push-pull member is connected between the transmission shaft 220 and the pushing shaft 313 to drive the pushing shaft 313 to move inside the bucket body 100. When the pushing shaft 313 moves inside the bucket body 100, the pushing bottom plate 311 and the pushing side plate 312 of the pushing plate 310 move under the drive of the pushing shaft 313. The pusher plate 310 has a transport position and a pusher position. The push-pull component moves the pusher shaft 313 to switch the pusher plate 310 between the transport position and the pusher position. During the process of the ore feeder 700 dumping ore into the ore bucket and the ore bucket transporting ore, such as... Figure 1 and Figure 2 As shown, the baffle plate 210 closes the discharge port 150, and the pusher plate 310 is always in the transport position. At this time, the pusher bottom plate 311 horizontally covers the bottom plate 110, and the pusher side plate 312 vertically covers the second side plate 130, with the ore above the pusher bottom plate 311. When the ore hopper reaches the unloading area and needs to be unloaded, as... Figure 3 and Figure 4As shown, the baffle plate 210 opens the discharge port 150, and the push-pull component drives the pusher shaft 313 to move. First, the pusher shaft 313 is driven to rise and move towards the discharge port 150, so that the pusher plate 310 in the transport position moves to the pusher position. During this process, the pusher bottom plate 311 and the pusher side plate 312 are tilted towards the discharge port 150 to assist the ore above the pusher bottom plate 311 to slide towards the discharge port 150 and be unloaded into the unloading area through the discharge port 150. Then, the pusher shaft 313 is driven to reset, so that the pusher plate 310 in the pusher position moves back to the transport position to wait for loading ore again.

[0026] This invention configures the ore hopper as a baffle assembly 200 with an openable / closeable discharge port 150 on one side, and an internal pusher assembly 300. This allows the pusher assembly 300 with the discharge port 150 closed and the pusher plate 310 in the transport position to work in conjunction with the hopper body 100 to hold the ore during loading and transportation. When the pusher plate 310 is in the transport position, the pusher bottom plate 311 horizontally covers the bottom plate 110, and the pusher side plate 312 vertically covers the second side plate 130. Both occupy minimal space within the hopper body 100, thus having a minimal impact on the ore loading capacity, maximizing the ore loading capacity of the hopper. During unloading, the motor 230 can drive the baffle plate 210 to rotate. With the discharge port 150 opened, the pusher shaft 313, driven by the pusher, can move the pusher plate 310 to the pusher position, so that the horizontally extending pusher bottom plate 311 and the vertically extending pusher side plate 312 become inclined towards the discharge port 150, in order to assist all the ore to slide towards the discharge port 150, realizing automatic ore unloading from the ore bucket. No manual assistance from the staff is required on site, and the ore in the ore bucket can be automatically unloaded, avoiding long-term pollution of ore dust in the mine and ensuring the health of the staff. At the same time, the inclined pusher bottom plate 311 and pusher side plate 312 can also prevent the ore from accumulating at the angle between the pusher bottom plate 311 and pusher side plate 312, so as to ensure complete ore unloading.

[0027] In order to ensure the stable change of the tilt angle of the pusher base plate 311 when the pusher shaft 313 moves, this embodiment provides a limiting shaft 330 on the side of the pusher base plate 311 near the discharge port 150. The pusher base plate 311 is rotatably connected to the two first side plates 120 through the limiting shaft 330. That is, when the pusher shaft 313 drives one side of the pusher base plate 311 to move, the side near the discharge port 150 always rotates around the limiting shaft 330. This allows the slope of the pusher base plate 311 to be controlled according to the different viscosities of the ore, thereby ensuring that the ore can be completely discharged. It also avoids the large gap caused by the change in height of the side of the pusher base plate 311 near the discharge port 150, thus preventing the ore from accumulating in the gap.

[0028] In this embodiment, the push-pull component is preferably an electric push rod 320. The electric push rod 320 drives the pusher shaft 313 to move by extending and retracting, thereby causing the pusher plate 310 to switch between the transport position and the pusher position. The electric push rod 320 has the advantages of high precision and high load capacity. Because all the ore in the hopper is on the pusher bottom plate 311, the push-pull component has a large load when pulling the pusher shaft 313 on one side of the pusher bottom plate 311. Using the electric push rod 320 as the push-pull component can stably pull the pusher shaft 313 under high load, extending the service life of the push-pull component. At the same time, the high precision of the electric push rod 320 can ensure precise control of the slope of the pusher bottom plate 311, reducing the difficulty of unloading ore. Of course, it is understandable that in another embodiment, a pull chain can also be used as the push-pull component. One end of the pull chain is wound around the drive shaft, and the other end is connected to the push shaft. The drive shaft rotates to retract and extend the pull chain, thereby changing the length of the pull chain between the drive shaft and the push shaft, and thus driving the push shaft to move, so that the push plate switches between the transport position and the push position. The pull chain structure is simple and reduces the production cost of the push-pull component.

[0029] In this embodiment, when the pusher plate 311 is in the transport position, it completely covers the bottom plate 110 of the bucket body 100. That is, the two sides of the pusher plate 311 abut against the first side plate 120, so that when the pusher plate 311 is tilted, all the ore can be pushed to slide towards the discharge port 150, improving the unloading effect. Because the pusher plate 311 is large, it is easy to deform due to uneven force. Therefore, in order to ensure that the pusher plate 310 is subjected to uniform force, this embodiment preferably provides two push-pull members. The two push-pull members are located on both sides of the pusher plate 310 and are respectively connected to the two ends of the pusher shaft 313.

[0030] To prevent the top of the pusher side plate 312 from shaking when it is in the transport position, this embodiment provides an electric lock 400 on the first side plate 120. When the pusher side plate 312 is in the transport position, the electric lock 400 locks the pusher side plate 312 to lock the pusher side plate 312 in the transport position, so that the pusher side plate 312 is stably maintained in the transport position during the transport of the ore bucket, avoiding the pusher side plate 312 from shaking. This also avoids the noise caused by the shaking of the pusher side plate 312 during the transport process, and also avoids the shaking pusher side plate 312 changing its angle and affecting the loading of ore. When it is necessary to unload the ore, the electric lock 400 unlocks the pusher side plate 312, so that the pusher side plate 312 can move under the drive of the pusher shaft 313. Preferably, the pusher side plate 312 is provided with an insertion hole facing the first side plate 120, and the electric lock 400 has a retractable locking pin. The locking pin is horizontally inserted into the insertion hole to lock the pusher side plate 312 in the transport position. The structure is simple and reliable.

[0031] Example 2:

[0032] An automated loading and unloading system for rail-based ore transportation in mines, such as Figure 5 and Figure 6 As shown, the system includes the ore transport vehicle in the above embodiment, as well as a control module, a track 500, an ore discharge machine 700, and a first video detection device 910. A drive module is provided on the tractor head 600 to drive the tractor head 600 to move or stop. Under the drive of the drive module, the tractor head 600 of the ore transport vehicle can drive multiple buckets 100 to move along the track 500 between the loading area (i.e., the area for loading ore into the buckets 100) and the unloading area (i.e., the area for unloading ore from the buckets 100). Both the ore discharge machine 700 and the first video detection device 910 are located in the ore loading area. The ore discharge machine 700 is located on one side of the track 500, and the first video detection device 910 is located on the other side of the track 500 and is set opposite to the ore discharge machine 700. The ore discharge machine 700 is used to dump ore into the bucket 100, and the first video detection device 910 is used to collect image information of the bucket 100 opposite to the ore discharge machine 700. Multiple parking points 800 are provided on one side of the ore discharge machine 700.

[0033] Because the buckets 100 are connected by chains, and the buckets 100 are connected to the locomotive 600, the distances between the buckets 100 and between the buckets 100 and the locomotive 600 may change as the locomotive stops. This can lead to a problem where, when any bucket 100 is positioned between the ore discharger 700 and the first video detection device 910, the buckets 100 and the ore discharger 700 may not be precisely aligned. Consequently, when the ore discharger 700 dumps ore into the positioned buckets 100, some of the ore may spill out. Spillage can lead to poor ore loading. The first video detection device 910 can collect image information of the buckets 100 opposite to the ore feeder 700. The control module can determine whether the buckets 100 are aligned with the ore feeder 700 based on the image information collected by the first video detection device 910, and adjust the position of the corresponding buckets 100 through the drive module to ensure precise alignment between the buckets 100 and the ore feeder 700, thereby improving loading efficiency. Of course, it is understandable that the control module can also determine whether the buckets 100 are full based on the image information collected by the first video detection device 910 during loading.

[0034] The automatic loading and unloading system in this embodiment also includes a second video detection device 920. The second video detection device 920 is located in the unloading area to collect image information of all buckets 100 in the unloading area. The control module can determine whether all buckets 100 have entered the unloading area based on the image information collected by the second video detection device 920. It can also control the movement of the tractor head 600 through the drive module to adjust the position of the buckets 100. When all buckets 100 enter the unloading area, the control module controls the pushing components of each bucket 100 to push out the ore in each bucket 100 at the same time, ensuring that all buckets 100 accurately unload the ore into the storage area, thus achieving fully automatic and accurate unloading.

[0035] Preferably, a weight detection device connected to the control module is provided on the base plate. When the pushing assembly is in the transport position, the weight detection device is located between the base plate and the pushing base plate, and the pushing base plate abuts against the weight detection device. The weight detection device can detect the weight of the material above it through the pushing base plate. When loading ore into bucket 100, the control module can detect the weight of the ore inside bucket 100 through a weight detection device. When the weight of the ore inside bucket 100 reaches a set value, the control module will stop the ore discharger 700 from dumping the ore, thus preventing the ore from overflowing from bucket 100 and reducing the difficulty of loading. When unloading ore from bucket 100, the control module can detect the remaining amount of ore inside bucket 100 through a weight detection device. If the ore in bucket 100 fails to leave the bucket 100 during the initial push of the pushing component due to reasons such as high ore viscosity, the control module will switch the pushing component from the transport position to the pushing position again to push the remaining ore in bucket 100 a second time, ensuring that bucket 100 can be completely unloaded with good unloading effect.

[0036] The operation process of the automated ore loading and unloading system is as follows: Step 1: The control module first controls the ore transport vehicle to move on the track 500 through the drive module. When the ore transport vehicle is in the loading area, the tractor 600 stops when it reaches the first stopping point 800 under the control of the control module, so that the first bucket 100 behind the tractor 600 passes and stops between the ore discharge machine 700 and the first video detection device 910.

[0037] Step 2: The first video detection device 910 collects image information of the bucket 100 opposite to the ore discharger 700. Then, the control module determines whether the bucket 100 is aligned with the ore discharger 700 based on the image information of the bucket 100 collected by the first video detection device 910. If the bucket 100 is precisely aligned with the ore discharger 700, the control module controls the ore discharger 700 to pour ore into the bucket 100. If the bucket 100 is not precisely aligned with the ore discharger 700, the control module controls the ore transport vehicle to move through the drive module to make the bucket 100 precisely aligned with the ore discharger 700, and then controls the ore discharger 700 to pour ore into the bucket 100 to complete the loading of the bucket 100.

[0038] Step 3: After the first bucket 100 is loaded with ore, the truck head 600, under the control of the control module, stops at the second parking point 800, so that the second bucket 100 behind the truck head 600 passes and stops between the ore discharge machine 700 and the first video detection device 910. Then, the relevant work in Step 2 is performed again. The truck head 600 stops at each parking point 800 in sequence, so that when the bucket 100 passing the ore discharge machine 700 is aligned with the ore discharge machine 700, the control module controls the ore discharge machine 700 to work and dump the ore into the corresponding bucket 100, so as to complete the loading of all buckets 100.

[0039] Step 4: The control module controls the ore transport vehicle to move on track 500 through the drive module, so that the ore transport vehicle moves from the loading area to the unloading area, and then the tractor 600 stops at parking point 800 in the unloading area.

[0040] Step 5: The second video detection device 920 collects image information of all buckets 100 within the unloading area. The control module determines whether all buckets 100 have entered the unloading area based on the image information collected by the second video detection device 920. If all buckets 100 have entered the unloading area, the control module controls the material blocking components of each bucket 100 to open the discharge port, and then controls all pushing components to simultaneously push out the ore in each bucket 100, achieving automatic unloading. Then, the pushing components and material blocking components are reset. If any bucket 100 fails to enter the unloading area, the control module controls the ore transport vehicle to move through the drive module to bring all buckets 100 into the unloading area, and then controls the material blocking components and pushing components on the buckets 100 to unload the ore.
