Description

Technical Field

[0001] The present invention relates to the technical field of transport vehicles, and in particular to a screw-propelled wetland general-purpose transport vehicle. Background Art

[0002] The wetland environment has muddy and soft ground conditions. Ordinary transport vehicles are easily stuck in the mud in this environment, making it difficult to start or even unable to continue driving. Once stuck in the mud, it will not only affect the transportation efficiency, but may also require manual rescue or long waiting, greatly increasing the cost and time consumption.

[0003] In addition, shallow water areas may be encountered in wetland environments. Traditional transport vehicles may easily get stuck in water and become unable to move after entering shallow water areas, or because the water resistance is relatively small, the vehicle may continue to move forward due to inertia, making it difficult to brake and posing a safety risk.

[0004] When the transport volume is large, the weight of traditional transport vehicles will increase, requiring the vehicle to overcome greater inertia when starting and stopping. Not only is starting difficult, but emergency braking is also more difficult, increasing safety risks.

[0036] As a further technical solution, the buffer pad and one end of the buoyancy plate facing the forward direction of the transport vehicle are shuttle-shaped.

[0037] The working principle and beneficial effects of the present invention are:

[0038] In the present invention, the frame is used as the main structure of the transport vehicle, and provides installation and support for other components. The isolation plate is arranged at the lower side of the frame, and forms an installation space with the frame. This installation space can be used to accommodate the drive or other components, and at the same time play a certain role of isolation and protection. The isolation plate has a through hole, which provides a channel for the lifting and lowering of the emergency stop part. The emergency stop part is arranged relative to the frame and is located in the installation space. Its lifting path passes through the through hole of the isolation plate. The emergency stop part can be lowered when needed, playing the role of emergency braking. The buoyancy plate is arranged relative to the isolation plate and is located below the isolation plate. It has an emergency stop perforation, and when the emergency stop part is lowered, it can penetrate the emergency stop perforation to realize the emergency stop function. The buoyancy plate may provide a certain buoyancy for the transport vehicle in special environments such as wetlands, thereby increasing the stability and passability of the transport vehicle. The spiral propulsion roller is rotatably arranged below the isolation plate. The rotation of the spiral propulsion roller can push the transport vehicle forward in complex terrains such as wetlands, and overcome muddy and soft ground conditions. The telescopic pusher is arranged on one side of the isolation plate. It can be extended to push obstacles such as mud in front of the transport vehicle, opening up a way forward for the transport vehicle. The connecting frame is arranged on the vehicle frame and is located at the lower side of the vehicle frame. The connecting frame cooperates with the telescopic push piece and the spiral propulsion roller to jointly maintain the stable operation and propulsion of the transport vehicle.

[0039] When the transport vehicle is stuck in the mud after an emergency stop, the starting torque of the spiral conveyor roller increases. Due to being stuck in the mud, the spiral conveyor roller is subjected to greater resistance, resulting in an increase in the starting torque. This makes it difficult to start the transport vehicle normally. In order to solve the problem of difficult starting, the buoyancy plate is lowered. The descent of the buoyancy plate generates an upward thrust, which causes the transport vehicle to rise as a whole. This can reduce the contact area between the transport vehicle and the mud and reduce resistance. As the transport vehicle rises as a whole, the spiral conveyor roller is suspended in the air. At this time, the spiral conveyor roller can rotate without the resistance of the mud. The purpose of the rotation is to generate forward propulsion to prepare for the transport vehicle to start again. When the spiral conveyor roller rotates, the buoyancy plate rises relative to the frame. This is to restore to the normal working position, while avoiding contact with the buoyancy plate and mud during the forward movement of the transport vehicle, increasing resistance, so as to ensure that the transport vehicle can start normally after the spiral conveyor roller enters the mud. Finally, when the spiral conveyor roller enters the mud again, since the previous rotation has generated a certain propulsion force, the normal start of the transport vehicle can be guaranteed at this time. The rotation of the spiral transport roller can push the silt backwards, thereby driving the transport vehicle forward, improving the reliability and adaptability of the transport vehicle in the complex wetland environment, avoiding the problem of being unable to continue driving due to being stuck in the silt, reducing the need for manual rescue or long waiting due to being stuck in the silt, and improving transportation efficiency.

[0040] In a wetland environment, a transport vehicle may enter a shallow water area, and the role of the buoyancy board is prominent at this time. The buoyancy board can provide sufficient buoyancy to keep the transport vehicle floating on the water surface, thereby ensuring the safety of the vehicle and preventing the vehicle from sinking into the water and being unable to drive. However, when the transport vehicle floats on the water surface, due to the relatively small resistance of the water, the vehicle may continue to move forward due to inertia, making it inconvenient to brake. This will bring certain safety risks, which may cause the vehicle to lose control and hit obstacles or enter dangerous areas. In order to solve the braking problem caused by inertia, the emergency stop plays an important role. The emergency stop quickly falls as an anchor and inserts into the wetland soil layer. Since the wetland soil layer usually has a certain friction and stability, the emergency stop can quickly stop the transport vehicle from moving forward after insertion. The rapid fall of the emergency stop and the action of inserting into the soil layer can generate greater resistance in a short time, allowing the transport vehicle to stop quickly. This ensures the emergency stop needs of the transport vehicle in shallow water areas or other special situations, and improves the safety and controllability of the vehicle. This design enables the transport vehicle to adapt to different situations in the wetland environment, including shallow water areas and muddy areas. The combination of buoyancy plates and emergency stop parts ensures that the transport vehicle can maintain a safe and stable operating state in various complex environments. Whether in shallow water or other situations, the existence of emergency stop parts provides a reliable emergency braking method for the transport vehicle, which greatly improves the safety of the vehicle and reduces the possibility of accidents.

[0041] Once the transport vehicle stops suddenly in a muddy environment, mud will accumulate in front of the spiral conveyor roller. This accumulated mud will produce greater resistance to the transport vehicle, making it more difficult to start and stop the transport vehicle. This not only affects the transportation efficiency, but may also cause the vehicle to fail to operate normally. In order to solve this problem, the transport vehicle is equipped with a telescopic push piece. The telescopic push piece is set on one side of the isolation plate. When the vehicle needs to be started, the telescopic push piece extends to push the mud in front of the vehicle. By pushing the mud, the telescopic push piece can clear a channel, reduce the resistance of the mud to the vehicle, and facilitate the starting of the vehicle. This design makes the transport vehicle more adaptable in a muddy environment. The telescopic push piece can effectively deal with the problem of mud accumulation and ensure that the vehicle can still operate normally under harsh working conditions. Facilitating the starting of the vehicle means reducing the time wasted due to difficulties in starting and stopping, and improving transportation efficiency. The transport vehicle can complete the transportation task faster and meet the needs of production and work. In a muddy environment, difficulties in starting and stopping may cause the vehicle to lose control or sink into deeper mud, posing a danger to the operator and the vehicle. The use of telescopic push pieces can reduce this risk and ensure safe operation.

[0042] When the transport volume of the spiral transporter is large, the overall weight of the vehicle will increase, which will bring greater pressure to the various components of the vehicle. When the vehicle is under high load for a long time, the structure of the vehicle is easily damaged, which will affect the service life of the vehicle. After the self-weight increases, the vehicle needs to overcome greater inertia when starting and stopping. This not only requires more power when starting, but also makes emergency braking more difficult, increasing safety risks. The connecting frame can connect the transport vehicle sections and disperse the transport volume to multiple sections. In this way, the weight borne by each part is relatively reduced, which reduces the pressure on the individual vehicle parts, thereby reducing the damage to the overall structure of the vehicle and helping to extend the service life of the vehicle. When the transport volume is dispersed, the inertia force of the vehicle when starting and stopping is also reduced accordingly. This makes it easier to start and the required power is relatively reduced. At the same time, in emergency braking, the vehicle can stop faster, which improves safety and convenience of operation and solves the problem of difficulty in starting and stopping. The design of the connecting frame solves the problem without reducing the transport capacity of the transporter. On the contrary, by reasonably allocating the transport volume, the transporter can carry out the transportation task more efficiently, improving the overall transportation efficiency. This design enables the spiral transporter to better adapt to the needs of different transport volumes. Whether it is a small amount of cargo transportation or a large-scale transportation task, the best transportation effect can be achieved by adjusting the number of connected vehicle sections. Reducing dead weight and optimizing start-stop performance help improve the safety and stability of the vehicle. It reduces the risk of vehicle failure during driving and provides more reliable protection for operators and goods. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Reference Figure 1 to Figure 7, which is the first embodiment of the present invention, proposes a spiral-propelled wetland general transport vehicle, including a frame 1, an isolation plate 2 is arranged at the lower side of the frame 1, and forms an installation space 101 with the frame 1, the isolation plate 2 has a through hole 201, the emergency stop part 3 is arranged to be lifted and lowered relative to the frame 1, the emergency stop part 3 is located in the installation space 101, the emergency stop part 3 is configured to have a lifting path passing through the through hole 201, the buoyancy plate 4 is arranged to be lifted and lowered relative to the isolation plate 2, and is located below the isolation plate 2, the buoyancy plate 4 has an emergency stop through hole 401, the emergency stop part 3 is configured to pass through the emergency stop through hole 401 after descending, the spiral propulsion roller 5 is rotatably arranged below the isolation plate 2, the telescopic push member 6 is arranged on one side of the isolation plate 2, the connecting frame 7 is arranged on the frame 1, and is located at the lower side of the frame 1, the connecting frame 7 and the telescopic push member 6 are respectively arranged on both sides of the spiral propulsion roller 5, and the telescopic push member 6 is used to push the sludge in front of the transport vehicle after being extended.

[0057] In this embodiment, the frame 1 serves as the main structure of the transport vehicle, providing installation and support for other components. The isolation plate 2 is arranged on the lower side of the frame 1, and forms an installation space 101 with the frame 1. This installation space 101 can be used to accommodate drive or other components, and at the same time play a certain role of isolation and protection. The isolation plate 2 has a through hole 201, which provides a channel for the lifting and lowering of the emergency stop part 3. The emergency stop part 3 is set to be lifted relative to the frame 1 and is located in the installation space 101. Its lifting path passes through the through hole 201 of the isolation plate 2. The emergency stop part 3 can be lowered when needed, playing the role of emergency braking. The buoyancy plate 4 is set to be lifted relative to the isolation plate 2 and is located below the isolation plate 2. It has an emergency stop perforation 401, and when the emergency stop part 3 is lowered, it can pass through the emergency stop perforation 401 to realize the emergency stop function. The buoyancy plate 4 may provide a certain buoyancy for the transport vehicle in special environments such as wetlands, thereby increasing the stability and passability of the transport vehicle. The spiral propulsion roller 5 is rotatably arranged below the isolation plate 2. The rotation of the spiral propulsion roller 5 can push the transport vehicle forward in complex terrain such as wetlands, and overcome muddy and soft ground conditions. The telescopic push member 6 is arranged on one side of the isolation plate 2. It can be extended to push obstacles such as mud in front of the transport vehicle, and open up a way for the transport vehicle to move forward. The connecting frame 7 is arranged on the frame 1 and is located at the lower side of the frame 1. The connecting frame 7 cooperates with the telescopic push member 6 and the spiral propulsion roller 5 to jointly maintain the stable operation and propulsion of the transport vehicle.

[0058] When the transport vehicle is stuck in the mud after an emergency stop, the starting torque of the spiral transport roller increases. Due to being stuck in the mud, the spiral transport roller is subjected to greater resistance, resulting in an increase in the starting torque. This makes it difficult to start the transport vehicle normally. In order to solve the problem of difficult starting, the buoyancy plate 4 is lowered. The descent of the buoyancy plate 4 generates an upward thrust, which causes the transport vehicle to rise as a whole. This can reduce the contact area between the transport vehicle and the mud and reduce resistance. As the transport vehicle rises as a whole, the spiral transport roller is suspended. At this time, the spiral transport roller can rotate without the resistance of the mud. The purpose of the rotation is to generate forward propulsion to prepare for the restart of the transport vehicle. When the spiral transport roller rotates, the buoyancy plate 4 rises relative to the frame 1. This is to restore to the normal working position, while avoiding contact with the buoyancy plate 4 and the mud during the forward movement of the transport vehicle, increasing resistance, so as to ensure that the transport vehicle starts normally after the spiral conveying roller enters the mud. Finally, when the spiral conveying roller enters the mud again, since the previous rotation has generated a certain propulsion force, the normal start of the transport vehicle can be guaranteed at this time. The rotation of the spiral transport roller can push the silt backwards, thereby driving the transport vehicle forward, improving the reliability and adaptability of the transport vehicle in the complex wetland environment, avoiding the problem of being unable to continue driving due to being stuck in the silt, reducing the need for manual rescue or long waiting due to being stuck in the silt, and improving transportation efficiency.

[0059] The transport vehicle may enter shallow water in a wetland environment, and the role of the buoyancy board 4 is prominent at this time. The buoyancy board 4 can provide sufficient buoyancy to allow the transport vehicle to float on the water surface, thereby ensuring the safety of the vehicle and preventing the vehicle from being trapped in the water and unable to drive. However, when the transport vehicle floats on the water surface, due to the relatively small resistance of the water, the vehicle may continue to move forward due to inertia, which is not convenient for braking. This will bring certain safety risks and may cause the vehicle to lose control and hit an obstacle or enter a dangerous area. In order to solve the braking problem caused by inertia, the emergency stop 3 plays an important role. The emergency stop 3 falls quickly as an anchor and is inserted into the wetland soil layer. Since the wetland soil layer usually has a certain friction and stability, the emergency stop 3 can quickly stop the transport vehicle from moving forward after being inserted. The rapid fall of the emergency stop 3 and the action of inserting the soil layer can generate a large resistance in a short time, so that the transport vehicle stops quickly. This ensures the emergency stop requirements of the transport vehicle in shallow water or other special situations, and improves the safety and controllability of the vehicle. This design enables the transport vehicle to adapt to different situations in the wetland environment, including shallow water and muddy areas. The use of the buoyancy plate 4 and the emergency stop 3 ensures that the transport vehicle can maintain a safe and stable operating state in various complex environments. Whether in shallow water or other situations, the presence of the emergency stop 3 provides a reliable emergency braking means for the transport vehicle, which greatly improves the safety of the vehicle and reduces the possibility of accidents.

[0060] Once the transport vehicle stops suddenly in a muddy environment, mud will accumulate in front of the spiral conveyor roller. These accumulated muds will produce greater resistance to the transport vehicle, making it more difficult to start and stop the transport vehicle. This not only affects the transportation efficiency, but may also cause the vehicle to fail to operate normally. In order to solve this problem, the transport vehicle is equipped with a telescopic push piece 6. The telescopic push piece 6 is arranged on one side of the isolation plate 2. When the vehicle needs to be started, the telescopic push piece 6 extends to push the mud in front of the vehicle. By pushing the mud, the telescopic push piece 6 can clear a channel, reduce the resistance of the mud to the vehicle, and thus facilitate the starting of the vehicle. This design makes the transport vehicle more adaptable in a muddy environment. The telescopic push piece 6 can effectively deal with the problem of mud accumulation and ensure that the vehicle can still operate normally under harsh working conditions. Facilitating the starting of the vehicle means reducing the time wasted due to difficulties in starting and stopping, and improving transportation efficiency. The transport vehicle can complete the transportation task faster and meet the needs of production and work. In a muddy environment, difficulties in starting and stopping may cause the vehicle to lose control or fall into deeper mud, causing danger to the operator and the vehicle. The use of the telescopic push piece 6 can reduce this risk and ensure operational safety.

[0061] The spiral transporter will increase the overall weight of the vehicle when the transport volume is large, which will bring greater pressure to the various components of the vehicle. When the vehicle is in a high-load state for a long time, the structure of the vehicle is easily damaged, thereby affecting the service life of the vehicle. After the dead weight increases, the vehicle needs to overcome a greater inertial force when starting and stopping. This not only requires more power when starting, but also makes it more difficult during emergency braking, increasing safety risks. The connecting frame 7 can connect the transport vehicle sections and disperse the transport volume to multiple sections. In this way, the weight borne by each part is relatively reduced, reducing the pressure on a single vehicle part, thereby reducing damage to the overall structure of the vehicle and helping to extend the service life of the vehicle. When the transport volume is dispersed, the inertial force of the vehicle when starting and stopping is also reduced accordingly. This makes starting easier and the required power is relatively reduced. At the same time, during emergency braking, the vehicle can stop faster, improving safety and convenience of operation, and solving the problem of difficulty in starting and stopping. The design of the connecting frame 7 does not reduce the transport capacity of the transporter while solving the problem. On the contrary, by reasonably allocating the transport volume, the transporter can carry out the transport task more efficiently, improving the overall transport efficiency. This design enables the spiral transporter to better adapt to the needs of different transport volumes. Whether it is a small amount of cargo transportation or a large-scale transportation task, the best transportation effect can be achieved by adjusting the number of connected vehicle sections. Reducing dead weight and optimizing start-stop performance help improve the safety and stability of the vehicle. It reduces the risk of vehicle failure during driving and provides more reliable protection for operators and goods.

[0062] Furthermore, it also includes a buffer pad 8, which is arranged below the isolation plate 2, and the buoyancy plate 4 is arranged on the lower side of the buffer pad 8. The buffer pad 8 has a through slot 801, and the emergency stop member 3 is configured to pass through the through slot 801 after descending, and the through hole 201, the through slot 801 and the emergency stop through hole 401 are configured to be connected in sequence.

[0063] In this embodiment, the buffer pad 8 is arranged below the isolation plate 2 to buffer and protect the transport vehicle. The buffer pad 8 has a through groove 801 to provide a channel for the emergency stop part 3 to descend, and cooperates with the through hole 201 of the isolation plate 2 and the emergency stop hole 401 of the buoyancy plate 4, so that the emergency stop part 3 can pass through these parts in sequence during the descent process to achieve the emergency stop function. Located on the lower side of the buffer pad 8. The buoyancy plate 4 provides buoyancy for the transport vehicle in a wetland environment, helping the vehicle to overcome muddy and soft ground conditions, and cooperates with the emergency stop part 3 to achieve emergency braking.

[0064] During the operation of the transport vehicle, the buffer pad 8 can reduce the impact and vibration from the ground and protect other parts of the vehicle from damage. Especially in complex terrains such as wetlands, the vehicle may encounter uneven ground and obstacles. The buffer pad 8 can effectively absorb the impact force and improve the stability and reliability of the vehicle. The through hole 201, the through groove 801 and the emergency stop perforation 401 are connected in sequence, providing an accurate path for the descent of the emergency stop part 3. This design ensures that the emergency stop part 3 can quickly and accurately pass through each component when needed to achieve emergency braking. It avoids the situation where the emergency stop function fails due to position deviation between components or blocked channels. The combined use of the buffer pad 8 and the buoyancy plate 4 further enhances the stability of the transport vehicle in a wetland environment. The buoyancy plate 4 provides buoyancy, and the buffer pad 8 reduces the vibration caused by ground obstacles to the frame 1 and / or the partition. The two work together to make the vehicle more stable during driving and emergency stopping, reducing the risk of accidents caused by unstable factors. This structural design makes each component relatively independent, which is convenient for maintenance and adjustment. The cushion pad 8 is made of lightweight material, which increases the buoyancy of the vehicle when the transport vehicle is traveling in shallow water areas. If a fault occurs or parameter adjustment is required, the cushion pad 8, buoyancy plate 4 or emergency stop part 3 can be operated separately, reducing maintenance costs and difficulty.

[0065] Furthermore, the cushion 8 is an air cushion.

[0066] In this embodiment, the air cushion is used as a buffer pad 8, and its simple structure means that it is more convenient and quick in the production and installation process, reducing the production cost and assembly difficulty. The light weight reduces the overall load of the transport vehicle, which helps to improve the maneuverability and passability of the vehicle and reduce energy consumption for transport vehicles traveling in wetlands and other environments that are sensitive to vehicle weight. In wetland environments, buoyancy is an important factor for the transport vehicle to maintain stability and safe driving. The air cushion can provide more buoyancy, so that the transport vehicle can float better in the water and avoid being stuck too deep and unable to drive. By inflating and exhausting the air cushion, the lifting and lowering of the buoyancy board 4 can be conveniently achieved. When it is necessary to increase the buoyancy or raise the transport vehicle, the air cushion is inflated, and the expansion of the air cushion pushes the buoyancy board 4 down; when it is necessary to reduce the buoyancy or adjust the height of the vehicle, the exhaust causes the air cushion to shrink, and the buoyancy board 4 rises accordingly. This flexible lifting method provides great convenience for the operation of the transport vehicle in different working scenarios. The inflation and deflation operation is relatively simple and quick, and can be completed in a short time, so that the transport vehicle can respond quickly to different road conditions and work requirements. The operator can adjust the state of the air cushion at any time according to the actual situation to achieve the best driving performance and working effect. The inflation and deflation function of the air cushion enhances the adaptability of the transport vehicle to various complex environments. Whether it is waters of different depths, wetlands of different muddy degrees, or the need to adjust the height of the vehicle to adapt to loading and unloading of goods, the needs can be met by inflation and deflation, which improves the versatility and practicality of the transport vehicle.

[0067] Furthermore, it also includes a first connecting member 9, which is arranged on the connecting frame 7 and is located on the side of the connecting frame 7 away from the frame 1. The first connecting member 9 has a sliding cavity 901. Several first connecting members 9 are arranged in sequence. The second connecting member 10 is slidably arranged in the sliding cavity 901. An elastic buffer member 11 is arranged in the sliding cavity 901, one end of which acts on the first connecting member 9 and the other end acts on the second connecting member 10 to provide a force for the second connecting member 10 to slide out of the sliding cavity 901. A mounting frame 12 is arranged on the second connecting frame 7 for mounting a trailer.

[0068] In this embodiment, the first connecting member 9 is arranged on the connecting frame 7 and is located on the side of the connecting frame 7 away from the frame 1, and has a sliding cavity 901. The first connecting member 9 is arranged in sequence for a plurality of first connecting members 9, which provides a basis for the subsequent cooperation with the second connecting member 10. The second connecting member 10 is slidably arranged in the sliding cavity 901 of the first connecting member 9, and can slide relatively in the sliding cavity 901. The elastic buffer 11 is arranged in the sliding cavity 901, one end of which acts on the first connecting member 9 and the other end of which acts on the second connecting member 10. It provides the force for the second connecting member 10 to slide out of the sliding cavity 901, and plays a role of buffering and adjusting in the connection process. The mounting frame 12 is arranged on the second connecting member 10, and is used to mount the trailer to realize the expansion function of the transport vehicle. The combined design of the first connecting member 9 and the second connecting member 10 makes the connection between the transport vehicle and the trailer more flexible. The second connecting member 10 can slide in the sliding cavity 901, which can adapt to different distance changes, and improve the adaptability and reliability of the connection. The elastic buffer 11 plays a buffering role in the connection process. When the transport vehicle is traveling on complex terrain such as wetlands, bumps and vibrations will occur. The elastic buffer 11 can absorb these impact forces, reduce the impact on the connection parts and the trailer, and protect the safety of the vehicle and cargo. The mounting frame 12 is arranged on the second connecting member 10, providing a convenient interface for mounting the trailer. The operator can easily connect the trailer with the transport vehicle to achieve extended transportation of goods and improve transportation efficiency. By mounting the trailer, the transportation capacity of the transport vehicle is significantly improved. More goods or equipment can be transported at one time to meet the needs of large-scale transportation, especially in areas with inconvenient transportation such as wetlands. This expanded transportation capacity is particularly important. The reasonable connection design and the role of the elastic buffer 11 enable the transport vehicle to maintain good stability after mounting the trailer. The shaking and instability factors during driving are reduced, and the safety and comfort of driving are improved.

[0069] Furthermore, a buffer space 1201 is formed between the mounting frame 12 and the connecting frame 7, the first connecting member 9 and the second connecting member 10 are both located in the buffer space 1201, and also include a flexible buffer member 13, the flexible buffer member 13 is arranged on the connecting frame 7 and is located in the buffer space 1201, the first locking member 14 is swingably arranged relative to the connecting frame 7, and has the first locking member 14, the second locking member 15 is arranged on the mounting frame 12, and has the second locking member 15, and the second locking member 15 is configured so that after the second connecting member 10 slides, the second locking member 15 is connected to the first locking member 14.

[0070] In this embodiment, the buffer space 1201 formed between the mounting frame 12 and the connecting frame 7 provides a location for other components to be placed, and at the same time plays a buffering role during transportation, reducing the impact of the impact force caused by bumps, vibrations, etc. on the connection part. The flexible buffer 13 is arranged on the connecting frame 7 and is located in the buffer space 1201, which further enhances the buffering effect. The flexible buffer 13 can absorb and alleviate the impact force from different directions, protect the connection part and the mounted trailer. The first lock 14 is swingably arranged relative to the connecting member, and has a first lock 14. Its swinging design allows it to flexibly cooperate with the second lock 15 when locking is required to achieve the locking function of the connection. The second lock 15 is arranged on the mounting frame 12 and has a second lock 15. When the second connecting member 10 slides, the action of connecting the second lock 15 with the first lock 14 is triggered, thereby ensuring a firm connection between the mounting frame 12 and the connecting frame 7.

[0071] Due to the effect of inertia, when the transport vehicle stops suddenly, the trailer will continue to move forward. If there are no corresponding measures, the trailer will collide with the frame 1 of the transport vehicle, causing damage to the vehicle and the cargo. The first lock 14 and the second lock 15 play an important locking role in this case. When the vehicle stops suddenly, the second connecting member 10 slides under the action of inertia, triggering the second lock 15 to connect with the first lock 14, and firmly locking the mounting frame 12 and the connecting frame 7 together. This locking can effectively prevent the movement of the trailer under the action of inertia and elasticity, and avoid repeated collisions between the trailer and the frame 1. By locking, the impact force caused by the collision is reduced, the structural integrity of the transport vehicle and the trailer, as well as the safety of the cargo on the vehicle are protected, and problems such as vehicle damage and cargo scattering caused by collision are avoided, thereby improving the safety and reliability of transportation.

[0072] The transport vehicle is designed with an elastic buffer 11, one end of which acts on the first connecting member 9 and the other end acts on the second connecting member 10. In the emergency stop state, the elastic buffer 11 is in a state of storing elastic potential energy. When starting, the elastic buffer 11 first releases the elastic potential energy. Due to the effect of the elastic buffer 11, there is no need to immediately overcome the resistance brought by the trailer at the moment of starting. Under the action of factors such as inertia, the connection force between the trailer and the transport vehicle is alleviated to a certain extent during the process of the elastic buffer 11 releasing the elastic potential energy. This means that the transport vehicle does not need to bear all the resistance from the trailer at once when starting, thereby reducing the power required at the moment of starting. The starting process of the transport vehicle is achieved through the action of the elastic buffer 11. First, the elastic buffer 11 releases the elastic potential energy, adjusts the connection structure, and reduces the influence of the trailer resistance; then gradually increases the power output, so that the transport vehicle and the trailer start to move as a whole. This hierarchical starting method is similar to gradually increasing the load, avoiding the instantaneous excessive load at the start, and protecting the vehicle's power system and transmission system.

[0073] Reduce the power required for vehicle startup: Through staged startup, the power required for startup is effectively reduced, which is very important for transport vehicles operating in complex environments such as wetlands. In wetland environments, the ground resistance is large, and vehicle startup itself is difficult. Reducing the startup power requirement can improve the vehicle's startup performance and reliability. It avoids the impact of instantaneous high loads on vehicle components during startup, reduces the risk of wear and damage, and thus extends the service life of the vehicle.

[0074] Furthermore, it also includes a swinging member 16, which is swingably set on the connecting frame 7, and the first locking member 14 is set on the swinging member 16. The swinging member 16 is configured so that the first locking member 14 and the second locking member 15 are unlocked after swinging. The first locking member 14 is located at one end of the swinging member 16, and the unlocking member 17 is arranged at the other end of the swinging member 16. The unlocking member 17 has an unlocking through hole 1701 and a hooked portion 1702. The emergency stop member 3 is configured to pass through the unlocking through hole 1701 and abut against the hooked portion 1702 after rising. After the emergency stop member 3 abuts against the hooked portion 1702, the hooked portion 1702 drives the swinging member 16 to swing, thereby achieving unlocking.

[0075] In this embodiment, the swinging member 16 is swingably arranged on the connecting frame 7. The first locking member 14 is arranged on the swinging member 16, and the swinging of the swinging member 16 can realize the unlocking of the first locking member 14 and the second locking member 15. The first locking member 14 is located at one end of the swinging member 16. The unlocking member 17 is arranged at the other end of the swinging member 16. It has an unlocking through hole 1701 and a hooked portion 1702. The emergency stop member 3 is configured to pass through the unlocking through hole 1701 after rising and abut against the hooked portion 1702. After the emergency stop member 3 abuts against the hooked portion 1702, the swinging member 16 is driven by the hooked portion 1702 to swing, thereby realizing unlocking. When unlocking is required, the swinging of the swinging member 16 can separate the first locking member 14 from the second locking member 15, thereby realizing the unlocking between the mounting frame 12 and the connecting frame 7. This unlocking method can be conveniently performed when it is necessary to separate the trailer or perform other operations. After rising, the emergency stop member 3 can abut against the hooked portion 1702 of the unlocking member 17, and unlocking can be achieved by driving the swinging member 16 to swing through the hooked portion 1702. This design allows unlocking to be achieved through the action of the emergency stop member 3 in certain circumstances, such as in an emergency or when quick unlocking is required, thereby improving the flexibility and safety of operation. The synergy between the swinging member 16, the unlocking member 17 and the emergency stop member 3 enables the transport vehicle to achieve corresponding functions under different working conditions. When an emergency stop is required during normal driving, the first locking member 14 and the second locking member 15 are locked to reduce the reciprocating collision between the trailer and the transport vehicle; when unlocking is required, unlocking can be achieved by operating the swinging member 16 or by utilizing the rising action of the emergency stop member 3. This unlocking method can avoid unexpected situations during the unlocking process and improve the safety and reliability of unlocking. At the same time, it also provides operators with a variety of unlocking methods, which is convenient for operation in different working scenarios.

[0076] Furthermore, the first lock member 14 has a first guide surface 1401, and the second lock member 15 has a second guide surface 1501. The second lock member 15 is configured so that after the first guide surface 1401 abuts against the second guide surface 1501, the second lock member 15 pushes the swing member 16 to swing. After the swing member 16 swings, the first lock member 14 and the second lock member 15 are locked. The elastic member 18 also includes an elastic member 18, one end of which acts on the unlocking member 17, and the other end acts on the isolation plate 2, to provide a force for locking the first lock member 14 and the second lock member 15.

[0077] In this embodiment, the first lock 14 has a first guide surface 1401, and the second lock 15 has a second guide surface 1501. When the two lock parts are in contact, the guide surface plays a guiding role. One end of the elastic member 18 acts on the unlocking member 17, and the other end acts on the isolation plate 2. Provides a force to lock the first lock 14 and the second lock 15. When the second lock 15 abuts against the first guide surface 1401, due to the action of the guide surface, the second lock 15 will push the swing member 16 to swing. After the swing member 16 swings, the first lock 14 and the second lock 15 are locked. This design allows automatic locking without additional operation during the connection process, thereby improving the convenience and efficiency of the connection. The locking force provided by the elastic member 18 further enhances the connection stability between the first lock 14 and the second lock 15. When the transport vehicle stops suddenly, the force of the elastic member 18 can prevent the lock part from loosening, ensure that the mounting frame 12 and the connecting frame 7 remain firmly connected after the collision, and improve the safety of transportation. The presence of the elastic member 18 can adapt to different road conditions and transportation conditions. When unlocking is required, it is only necessary to overcome the force of the elastic member 18 and operate the unlocking member 17 or the emergency stop member 3 to achieve unlocking. This design makes it more convenient and quick for operators to separate the trailer or perform other operations. The hierarchical start makes the starting process smoother, reduces the probability of vehicle loss of control or other safety problems caused by excessive power at the moment of starting, and improves the stability and safety of operation.

[0078] Furthermore, the telescopic push piece 6 has a conical head 601 , and the conical head 601 is located at the end of the telescopic push piece 6 .

[0079] In this embodiment, the telescopic push member 6 has a conical head 601, and the conical head 601 is located at the end of the telescopic push member 6. The design of the conical head 601 makes it easier for the telescopic push member 6 to insert into obstacles such as mud in front of the transport vehicle when pushing them, reducing the resistance during the pushing process. The conical head 601 can first break the harder mud layer or other obstacles, creating better conditions for the subsequent overall pushing of the telescopic push member 6, and improving the efficiency of clearing obstacles.

[0080] Furthermore, the emergency stop member 3 has a hook portion 301, and the emergency stop member 3 is configured to abut against the hooked portion 1702 after rising, and hook into the wetland after descending. It also includes a lifting roller 19, and the lifting roller 19 is rotatably arranged in the installation space 101. The lifting chain 20 is wound around the lifting member, and one end of the lifting chain 20 is connected to the emergency stop member 3. The lifting roller 19 is configured to drive the emergency stop member 3 to rise or fall after rotating.

[0081] In this embodiment, the emergency stop member 3 has a hook portion 301, which can abut against the hooked portion 1702 of the unlocking member 17 after rising, and can hook into the wetland after falling. The lifting roller 19 is rotatably arranged in the installation space 101, and the lifting chain 20 is wound around the lifting member, and one end is connected to the emergency stop member 3. When the lifting roller 19 rotates, it can drive the emergency stop member 3 to rise or fall. This design makes the lifting and lowering operation of the emergency stop member 3 more convenient and precise. By controlling the rotation of the lifting roller 19, the emergency stop member 3 can be quickly raised to perform the unlocking operation, or lowered to hook it into the wetland to achieve emergency braking of the transport vehicle. The transmission method of the lifting chain 20 can ensure the stability and reliability of the emergency stop member 3 during the lifting process, and avoid jamming or unexpected situations.

[0082] After the emergency stop part 3 is hooked into the soil, the lifting roller 19 still lowers one end of the lifting chain 20. This operation allows the transport vehicle to retreat a certain distance when it needs to be started. Lowering the lifting chain 20 can adjust the connection state between the emergency stop part 3 and the soil, providing a certain amount of activity space for the transport vehicle to retreat. At the same time, the distance the transport vehicle retreats can also be accurately controlled by controlling the lowering length of the lifting chain 20. The transport vehicle retreats a certain distance to ensure that the first locking member 14 and the second locking member 15 are locked. In the emergency stop state, the locking part may be in an unstable state due to various reasons. By retreating, the locking part is tightly combined again to ensure the reliability of the connection during the startup process. This locking state is crucial for graded startup. Only when the locking part is locked can the operation be carried out according to the predetermined graded startup steps to ensure the smooth progress of the startup process. When the transport vehicle needs to be officially started, the emergency stop part 3 rises. After the emergency stop part 3 rises, it is disengaged from the hooked part 1702 of the unlocking member 17, thereby achieving unlocking. Unlocking is an important part of graded startup. Before unlocking, the transport vehicle is in a restricted state and cannot be started normally. Only when the emergency stop 3 rises and is unlocked, can the vehicle enter the next starting stage. The rising and unlocking process of the emergency stop 3 ensures that the hierarchical starting is guaranteed. Hierarchical starting requires a series of operations to be performed in a specific order, and the rising and unlocking of the emergency stop 3 is one of the key steps. By controlling the rising timing of the emergency stop 3, the process of hierarchical starting can be accurately controlled to ensure that each stage can be completed smoothly, thereby improving the reliability and stability of the starting. At the same time, this operation method can also prevent the telescopic push member 6 from pushing away less soil and affecting the starting of the vehicle. If the telescopic push member 6 does not push away enough soil before starting, it may increase the resistance when the vehicle starts, resulting in difficulty in starting. By retreating to lock the lock part and raising the emergency stop 3 to unlock it at the right time, it can ensure that the telescopic push member 6 has enough time and space to clean the soil in front, creating good conditions for starting the vehicle.

[0083] Furthermore, the end of the buffer pad 8 and the buoyancy plate 4 facing the forward direction of the transport vehicle is shuttle-shaped.

[0084] In this embodiment, the end of the buffer pad 8 and the buoyancy plate 4 facing the forward direction of the transport vehicle is shuttle-shaped. During the forward movement of the transport vehicle, the shuttle-shaped design can effectively reduce water resistance and soil resistance. When the transport vehicle is traveling in an environment such as a wetland, it often encounters water and muddy ground. The shuttle-shaped front end can more smoothly push away the water flow and mud, reduce resistance, make the transport vehicle travel more easily, and reduce power consumption. The shuttle-shaped front end shape helps to improve the passability of the transport vehicle. When encountering narrow passages or complex terrain, the shuttle-shaped design can make it easier for the transport vehicle to pass and reduce the risk of being stuck. Especially in wetlands, there may be various obstacles and narrow waterways. The shuttle-shaped buoyancy plate 4 and buffer pad 8 can better adapt to these environments and ensure that the transport vehicle can move forward smoothly. The shuttle-shaped design can also enhance the stability of the transport vehicle. When the transport vehicle is traveling, the shuttle-shaped front end can better guide the flow direction of water and mud, reduce the lateral impact on the vehicle body, and thus improve the stability of the transport vehicle. On unstable ground such as wetlands, stability is crucial for the safe driving of the transport vehicle. The shuttle-shaped design can protect the cushion 8, the buoyancy plate 4 and other related parts to a certain extent. When encountering a collision or impact, the front end of the shuttle can bear part of the force first, reducing the damage to the rear parts. At the same time, the shuttle shape can also make the force more evenly distributed on the entire structure, improving the durability of the parts.
