[0002] In the operation of logistics and freight, goods need to be classified according to different requirements, and then the classified goods are transferred. With the development of science and technology, AGV (Automated Guided Vehicle) vehicles have appeared in the market. These AGV vehicles can identify cargo information and then dispatch the cargo according to the set route based on the identified information, thereby improving the efficiency of cargo transfer and dispatch.

[0003] A prior art Chinese patent (CN110979506A) discloses an AGV (Automated Guided Vehicle) including a vehicle shell with wheels at the four corners of the lower part of the shell. The wheels are rotatably connected to a fixed frame. A wheel rotation assembly that drives the wheels to rotate along a horizontal axis is installed inside the shell. A wheel steering assembly that drives the shell to rotate along a vertical axis is also installed inside the shell. The wheel rotation assembly and the wheel steering assembly are stacked vertically. This invention provides an AGV that controls the rotation and steering of its wheels through a linkage assembly.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When using AGV carts to dispatch and transfer goods placed in the material bins, the material bins are placed directly on the frame for use, which makes them prone to slipping off the frame due to the shaking of the AGV cart.

[0007] field

[0008] This invention relates to the field of logistics and freight equipment technology, specifically to a cargo identification and scheduling device for logistics and freight.

[0009] In the operation of logistics and freight, goods need to be classified according to different requirements, and then the classified goods are transferred. With the development of science and technology, AGV (Automated Guided Vehicle) vehicles have appeared in the market. These AGV vehicles can identify cargo information and then dispatch the cargo according to the set route based on the identified information, thereby improving the efficiency of cargo transfer and dispatch.

[0010] A prior art Chinese patent (CN110979506A) discloses an AGV (Automated Guided Vehicle) including a vehicle shell with wheels at the four corners of the lower part of the shell. The wheels are rotatably connected to a fixed frame. A wheel rotation assembly that drives the wheels to rotate along a horizontal axis is installed inside the shell. A wheel steering assembly that drives the shell to rotate along a vertical axis is also installed inside the shell. The wheel rotation assembly and the wheel steering assembly are stacked vertically. This invention provides an AGV that controls the rotation and steering of its wheels through a linkage assembly. It has a simple structure, is suitable for small interior spaces, and offers flexible and efficient adjustments.

[0011] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When using AGV carts to dispatch and transfer goods placed in the material bins, the material bins are placed directly on the frame for use, which makes them prone to slipping off the frame due to the shaking of the AGV cart. This can cause the goods to spill out of the material bins or even be damaged, increasing the requirements of the AGV carts on the usage site and reducing the practicality of the AGV carts.

[0012] Therefore, we propose a cargo identification and scheduling device for logistics freight.

[0013] The purpose of this invention is to provide a cargo identification and scheduling device for logistics freight, so as to solve the problems mentioned in the background art.

[0014] To achieve the above objectives, the present invention provides the following technical solution: a cargo identification and dispatching device for logistics freight, comprising a frame, a control panel mounted on the side wall of the frame, four wheels mounted on the lower surface of the frame, and a material box placed on the upper surface of the frame; further comprising limiting structures respectively disposed on both sides of the frame to prevent the material box from slipping off the frame, the limiting structures comprising four electric push rods fixedly mounted on the side wall of the frame, a mounting plate for squeezing the material box, and several anti-slip tubes for increasing the friction between the mounting plate and the material box; a support structure respectively disposed on the side wall of the frame for supporting the material box during uphill operation, the support structure comprising an electric telescopic rod fixedly mounted on the side wall of the frame, two rotating plates and adjusting plates for supporting the material box, and two external pressure rods and internal pressure rods for adjusting the position of the rotating plates and adjusting plates; and a protective structure respectively disposed on the frame relative to the control panel for protecting the control panel, the protective structure comprising two lead screws, a buffer plate for buffering, and a flexible wire.

[0015] The aforementioned components achieve the following effects: By setting a limiting structure and using a horizontally sliding mounting plate to compress the material box, the position of the material box is restricted, minimizing the possibility of the material box slipping off the frame and causing goods to spill out or even break. This improves the frame's mobility, reduces the AGV's site requirements, and enhances its practicality. Furthermore, during emergency braking, two springs and friction pads cushion the material box and its contents, facilitating the placement of fragile items. A support structure, using adjusting plates and rotating plates to support the material box, prevents it from sliding along the frame surface when traveling uphill or on bumpy roads, thus increasing stability and further facilitating the placement of goods. A protective structure, using flexible wires to shield the control panel during frame movement, prevents direct impact with obstacles. Additionally, a buffer plate made of elastic steel cushions collisions, minimizing the risk of the flexible wires breaking and extending their lifespan.

[0016] Preferably, the output end of the electric actuator is fixedly connected to an L-shaped plate, and the surfaces of the long arms of the two L-shaped plates are fixedly connected to fixed blocks. A rectangular frame is slidably fitted onto the surface of the fixed block, and the rectangular frame is fixedly connected to the mounting plate. Several anti-slip tubes are evenly fixedly installed on the surface of the mounting plate. The anti-slip tubes are made of rubber, and a bent tube is fixedly connected to the inner wall of the anti-slip tube. The bent tube is made of SUS301 stainless steel, and the cross-section of the bent tube is "8". Springs are fixedly connected to both sides of the fixed block, and the other end of the spring is fixedly connected to the rectangular frame. A friction pad is fixedly connected to the side of the fixed block closest to the mounting plate. The friction pad is slidably connected to the mounting plate, and the friction pad is made of rubber.

[0017] The aforementioned components achieve the following effects: After the material box is placed on the upper surface of the frame, four electric actuators are activated simultaneously. The retraction of the output end of the electric actuators causes the L-shaped plate to slide, which in turn causes the fixing block to slide. The sliding of the fixing block causes the mounting plate to slide, and the sliding of the mounting plate causes the anti-slip tube to press against the outer wall of the material box. At this time, the rubber anti-slip tube will deform under pressure, increasing the friction between the mounting plate and the material box. It also helps to prevent rigid compression between the mounting plate and the material box, thus preventing damage to the material box and improving the limiting effect of the mounting plate on the material box. When the anti-slip tube deforms, it will compress the bent tube. At this time, the bent tube with an "8" shaped cross-section will fold together, transmitting the pressure on the anti-slip tube. This allows the anti-slip tube to be evenly stressed, improving its performance. Furthermore, the SUS301 stainless steel bent tube has the advantages of corrosion resistance and high elasticity, allowing the anti-slip tube to quickly return to its original shape when the material box is not in contact with it.

[0018] Preferably, two dust baffles are fixedly connected to the side of the fixed block away from the material box. The dust baffles are slidably connected to the rectangular frame, and the size of the dust baffles is adapted to the size of the rectangular frame.

[0019] The effect achieved by the above components is that when the rectangular frame slides along the surface of the dust baffle, the dust baffle can prevent stones from falling into the rectangular frame and causing the stones to affect the normal extension or contraction of the spring, thereby ensuring that the spring can properly buffer the rectangular frame.

[0020] Preferably, the surface of the rectangular frame has two strip holes, and the surface of the fixing block has two protrusions fixedly connected, with the protrusions slidably connected to the inner wall of the strip holes.

[0021] The effect achieved by the above components is that when the rectangular frame slides, the inner wall of the strip hole will slide along the surface of the protrusion. At this time, the protrusion restricts the sliding path of the rectangular frame and prevents the rectangular frame from losing contact with the fixed block as much as possible.

[0022] Preferably, a connecting plate is fixedly connected to the lower surface of the two short arms of the L-shaped plate, a support rod is fixedly connected to the lower surface of the connecting plate, and a ball bearing is rotatably connected to the lower end of the support rod.

[0023] The effect achieved by the above components is as follows: the connecting plate moves with the help of the L-shaped plate, which in turn drives the support rod to move. The movement of the support rod causes the ball bearings to roll along the ground. At this time, the support rod and the roller increase the contact area between the frame and the ground, thereby preventing the frame from tipping over during driving.

[0024] Preferably, the output end of the electric telescopic rod is fixedly connected to an arc-shaped plate, the inner pressure rod and the outer pressure rod are both fixedly connected to the upper surface of the arc-shaped plate, two fixed rods are fixedly connected to the upper surface of the frame, the two rotating plates are rotatably connected to the two fixed rods respectively, the rotating plates are slidably connected to the adjusting plate, the rotating plates are located between the inner pressure rod and the outer pressure rod, and one end of the adjusting plate is fixedly fitted with a rubber sleeve.

[0025] The above components achieve the following effect: when the electric telescopic rod is activated, the extension of the output end of the electric telescopic rod will cause the arc plate to slide. The sliding of the arc plate will cause the outer pressure rod to slide along the surface of the rotating plate and the adjusting plate. At this time, the outer pressure rod will squeeze the rotating plate and the adjusting plate, causing the two rotating plates to rotate towards each other along the arc surface of the fixed rod. The adjusting plate will rotate with the rotating plate, causing the rubber sleeve to press against the side wall of the material box. When the frame is traveling on an uphill road, the adjusting plate will support and lift the material box, trying to prevent the material box from sliding down the surface of the frame, thereby further improving the limiting effect of the material box.

[0026] Preferably, the surface of the adjusting plate is provided with a threaded hole, and a screw is threadedly connected to the inner wall of the threaded hole on the adjusting plate. A pressure plate is fixedly connected to the arc surface of the screw.

[0027] The effect achieved by the above components is as follows: when the screw is rotated, the screw will drive the pressure plate to move downwards through the thread. When the pressure plate contacts the rotating plate, the pressure plate will limit the position of the adjusting plate.

[0028] Preferably, a clamping plate is fixedly connected to the surface of the rotating plate, a limiting plate is fixedly connected to the upper surface of the arc-shaped plate, the vertical cross-section of the limiting plate is "H" shaped, and the clamping plate is slidably connected to the inner wall of the limiting plate.

[0029] The effect achieved by the above components is that the sliding of the arc plate will cause the limiting plate to slide along the surface of the clamping plate. At this time, the clamping plate will limit the sliding path of the limiting plate and prevent the limiting plate from rotating as much as possible, thereby limiting the sliding path of the arc plate.

[0030] Preferably, the lead screw is fixedly installed on the upper surface of the frame, a U-shaped plate is fixedly connected to the arc surface of the lead screw, a perforated plate is slidably connected to the inner wall of the U-shaped plate, the lead screw passes through the perforated plate, a round rod is rotatably connected to the side of the two perforated plates that are close to each other, both buffer plates are fixedly connected to the round rod, the buffer plates are made of elastic steel, a rectangular plate is fixedly connected to the end of the buffer plate away from the round rod, both ends of the flexible wire are fixedly connected to the two rectangular plates respectively, the flexible wire is made of transparent polypropylene, a threaded sleeve is threaded to the arc surface of the upper end of the lead screw, and the lower end of the threaded sleeve abuts against the surface of the perforated plate.

[0031] The aforementioned components achieve the following effects: When protection of the control panel is required, the perforated plate slides downwards along the arc of the lead screw. The perforated plate slides into the inner wall of the U-shaped plate, at which point the U-shaped plate restricts the position of the perforated plate. Then, the threaded sleeve is aligned with the lead screw and rotated. The threaded sleeve moves downwards with the help of the thread. When the threaded sleeve abuts against the surface of the perforated plate, it further restricts the position of the perforated plate. When the frame encounters an obstacle during travel, the rectangular plate and flexible wire will come into contact with the obstacle. At this time, the transparent polypropylene flexible wire will shield the control panel, minimizing the possibility of the control panel being damaged by contact with the obstacle. Simultaneously, the rectangular plate under pressure will cause the buffer plate to bend. The elastic steel buffer plate will cushion the collision between the control panel and the obstacle, minimizing the breakage of the flexible wire and extending its service life.

[0032] Preferably, a positioning rod is fixedly connected to the surface of the U-shaped plate, and the positioning rod is slidably connected to the buffer plate.

[0033] The effect achieved by the above components is that the buffer plate will come into contact with the positioning rod due to its own weight, and the positioning rod will restrict the position of the buffer plate, thereby maintaining a certain distance between the rectangular plate and the control panel.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] This invention uses a limiting structure with a horizontally sliding mounting plate to compress the material box, thereby restricting its position and preventing it from slipping off the frame and spilling or breaking goods. This improves the vehicle's mobility, reduces the AGV's site requirements, and enhances its practicality. Furthermore, during emergency braking, two springs and friction pads cushion the material box and its contents, making it convenient for storing fragile items.

[0036] This invention provides a support structure that uses an adjusting plate and a rotating plate to support the material box. This prevents the material box from sliding along the surface of the vehicle frame when the vehicle is traveling uphill, making the material box more stable and facilitating the use of the material box to hold goods.

[0037] This invention, by setting up a protective structure, uses flexible wires to shield and protect the control panel during vehicle movement, minimizing the possibility of the control panel directly colliding with obstacles. Furthermore, the use of a buffer plate made of elastic steel can cushion the impact in the event of a collision, minimizing the breakage of the flexible wires and extending their service life.

Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please see Figure 1-9This invention provides a technical solution: a cargo identification and scheduling device for logistics freight, including a frame 1, a control panel 2 installed on the side wall of the frame 1, four wheels 3 installed on the lower surface of the frame 1, and a material box 4 placed on the upper surface of the frame 1. It also includes limiting structures 5 respectively disposed on both sides of the frame 1 to prevent the material box 4 from slipping off the frame 1. The limiting structure 5 includes four electric push rods 501 fixedly installed on the side wall of the frame 1, a mounting plate 506 for pressing the material box 4, and several anti-slip tubes 507 for increasing the friction between the mounting plate 506 and the material box 4. A support structure 6, separately installed on the side wall of the frame 1, is used to support the material box 4 during uphill operation. The support structure 6 includes an electric telescopic rod 601 fixedly installed on the side wall of the frame 1, two rotating plates 606 and an adjusting plate 607 for supporting the material box 4, and two external pressure rods 603 and an internal pressure rod 604 for adjusting the position of the rotating plates 606 and the adjusting plate 607. A protective structure 7, respectively installed on the frame 1 relative to the control panel 2, is used to protect the control panel 2. The protective structure 7 includes two lead screws 71, a buffer plate 75 for buffering, and a flexible wire 77.

[0050] The following section will explain the specific design and function of its limiting structure 5, supporting structure 6, and protective structure 7.

[0051] like Figure 2-5As shown, an L-shaped plate 503 is fixedly connected to the output end of the electric actuator 501. Fixing blocks 504 are fixedly connected to the surfaces of the long arms of the two L-shaped plates 503. A rectangular frame 505 slides on the surface of the fixing block 504. The rectangular frame 505 is fixedly connected to the mounting plate 506. Several anti-slip tubes 507 are evenly fixedly installed on the surface of the mounting plate 506. The anti-slip tubes 507 are made of rubber. A bent tube 508, made of SUS301 stainless steel, is fixedly connected to the inner wall of the anti-slip tube 507. The cross-section of 508 is shaped like an "8". Springs 509 are fixedly connected to both sides of the fixing block 504. The other end of the springs 509 is fixedly connected to the rectangular frame 505. A friction pad 510 is fixedly connected to the side of the fixing block 504 closest to the mounting plate 506. The friction pad 510 is slidably connected to the mounting plate 506 and is made of rubber. After the material box 4 is placed on the upper surface of the frame 1, the four electric actuators 501 are activated simultaneously. The retraction of the output end of the electric actuators 501 causes the L-shaped plate 503 to slide. The sliding of plate 503 causes the fixing block 504 to slide, which in turn causes the mounting plate 506 to slide. The sliding of mounting plate 506 causes the anti-slip tube 507 to press against the outer wall of the hopper 4. At this time, the rubber anti-slip tube 507 will deform under pressure, increasing the friction between the mounting plate 506 and the hopper 4. Simultaneously, it helps to prevent rigid compression between the mounting plate 506 and the hopper 4, thus preventing damage to the hopper 4 and improving the limiting effect of the mounting plate 506 on the hopper 4. When the anti-slip tube 507 deforms, it will compress the bent tube 508. At this time, the bent tube 508, which has an "8" shaped cross-section, will fold together. The bent tube 508 can transmit the pressure on the anti-slip tube 507, so that the anti-slip tube 507 can be evenly stressed, thus improving the performance of the anti-slip tube 507. In addition, the bent tube 508, made of SUS301 stainless steel, also has the advantages of rust resistance and high elasticity. When the material box 4 is not in contact with the anti-slip tube 507, the anti-slip tube 507 can quickly return to its original shape.

[0052] like Figure 3 and Figure 4As shown, two dust baffles 513 are fixedly connected to the side of the fixing block 504 away from the material box 4. The dust baffles 513 are slidably connected to the rectangular frame 505. The size of the dust baffles 513 is adapted to the size of the rectangular frame 505. When the rectangular frame 505 slides along the surface of the dust baffles 513, the dust baffles 513 can prevent stone particles from falling into the rectangular frame 505 and causing the stone particles to affect the normal extension or contraction of the spring 509, thereby ensuring that the spring 509 can properly buffer the rectangular frame 505. Two strip holes 511 are opened on the surface of the rectangular frame 505. Two protrusions 512 are fixedly connected to the surface of the fixing block 504. The protrusions 512 are slidably connected to the inner wall of the strip holes 511. When the rectangular frame 505 slides, the inner wall of the strip holes 511 will slide along the surface of the protrusions 512. At this time, the protrusions 512 achieve the function of restricting the sliding path of the rectangular frame 505 and preventing the rectangular frame 505 from losing contact with the fixing block 504. A connecting plate 502 is fixedly connected to the lower surface of the two L-shaped plates 503 short arms. A support rod 514 is fixedly connected to the lower surface of the connecting plate 502. A ball bearing 515 is rotatably connected to the lower end of the support rod 514. When the connecting plate 502 moves with the help of the L-shaped plates 503, it will drive the support rod 514 to move. When the support rod 514 moves, it will drive the ball bearing 515 to roll along the ground. At this time, the support rod 514 and the roller will increase the contact area between the frame 1 and the ground, thereby preventing the frame 1 from tipping over during driving.

[0053] like Figure 6 and Figure 7 as well as Figure 8As shown, the output end of the electric telescopic rod 601 is fixedly connected to an arc-shaped plate 602. The inner pressure rod 604 and the outer pressure rod 603 are both fixedly connected to the upper surface of the arc-shaped plate 602. Two fixed rods 605 are fixedly connected to the upper surface of the frame 1. Two rotating plates 606 are rotatably connected to the two fixed rods 605 respectively. The rotating plate 606 is slidably connected to the adjusting plate 607. The rotating plate 606 is located between the inner pressure rod 604 and the outer pressure rod 603. One end of the adjusting plate 607 is fixedly fitted with a rubber sleeve 608. When the electric telescopic rod 601 is activated, the output end of the electric telescopic rod 601 extends, which drives the arc-shaped plate 602... 02 Sliding: The sliding of the arc plate 602 will cause the outer pressure rod 603 to slide along the surface of the rotating plate 606 and the adjusting plate 607. At this time, the outer pressure rod 603 will squeeze the rotating plate 606 and the adjusting plate 607, causing the two rotating plates 606 to rotate towards each other along the arc surface of the fixed rod 605. The adjusting plate 607 will rotate with the rotating plate 606, causing the rubber sleeve 608 to abut against the side wall of the material box 4. When the frame 1 is traveling on an uphill road, the adjusting plate 607 will support and lift the material box 4, trying to prevent the material box 4 from sliding down the surface of the frame 1, thereby further improving the limiting effect on the material box 4. The adjusting plate 607 has a threaded hole on its surface. A screw 611 is threaded onto the inner wall of the threaded hole on the adjusting plate 607. A pressure plate 612 is fixedly connected to the arc surface of the screw 611. When the screw 611 is rotated, it will drive the pressure plate 612 downward through the thread. When the pressure plate 612 contacts the rotating plate 606, the pressure plate 612 will limit the position of the adjusting plate 607. A clamping plate 609 is fixedly connected to the surface of the rotating plate 606. A limiting plate 610 is fixedly connected to the upper surface of the arc plate 602. The vertical cross-section of the limiting plate 610 is "H" shaped. The clamping plate 609 is slidably connected to the inner wall of the limiting plate 610. When the arc plate 602 slides, it will drive the limiting plate 610 to slide along the surface of the clamping plate 609. At this time, the clamping plate 609 will limit the sliding path of the limiting plate 610 and prevent the limiting plate 610 from rotating as much as possible, thereby limiting the sliding path of the arc plate 602.

[0054] like Figure 9As shown, a lead screw 71 is fixedly installed on the upper surface of the frame 1. A U-shaped plate 72 is fixedly connected to the arc surface of the lead screw 71. A perforated plate 73 is slidably connected to the inner wall of the U-shaped plate 72. The lead screw 71 passes through the perforated plate 73. A round rod 74 is rotatably connected to the side of the two perforated plates 73 that is close to each other. Two buffer plates 75 are fixedly connected to the round rod 74. The buffer plates 75 are made of elastic steel. A rectangular plate 76 is fixedly connected to the end of the buffer plate 75 away from the round rod 74. The two ends of a flexible wire 77 are fixedly connected to the two rectangular plates 76 respectively. The flexible wire 77 is made of transparent polypropylene. A threaded sleeve 78 is threaded to the arc surface of the upper end of the lead screw 71. The lower end of the threaded sleeve 78 abuts against the surface of the perforated plate 73. When it is necessary to protect the control panel 2, the perforated plate 73 is slid downward along the arc surface of the lead screw 71. The sliding of the perforated plate 73 will cause it to slide into the U-shaped plate 73. The inner wall of plate 72, at this time, U-shaped plate 72 serves to restrict the position of hole plate 73. Then, threaded sleeve 78 is aligned with lead screw 71 and threaded sleeve 78 is rotated. Threaded sleeve 78 will move downwards. When threaded sleeve 78 abuts against the surface of hole plate 73, threaded sleeve 78 further restricts the position of hole plate 73. When frame 1 encounters an obstacle during driving, rectangular plate 76 and flexible wire 77 will come into contact with the obstacle. At this time, the transparent polypropylene flexible wire 77 will shield control panel 2 to prevent control panel 2 from being damaged by contact with the obstacle. At the same time, the rectangular plate 76 will be compressed and cause buffer plate 75 to bend. Elastic steel buffer plate 75 will buffer the collision between control panel 2 and obstacle to prevent flexible wire 77 from breaking and extend the service life of flexible wire 77. A positioning rod 79 is fixedly connected to the surface of the U-shaped plate 72. The positioning rod 79 is slidably connected to the buffer plate 75. When the buffer plate 75 comes into contact with the positioning rod 79 due to its own weight, the positioning rod 79 will restrict the position of the buffer plate 75, thereby maintaining a certain distance between the rectangular plate 76 and the control panel 2.

[0055] Working principle: After the material box 4 is placed on the upper surface of the frame 1, the four electric actuators 501 are activated simultaneously. The retraction of the output end of the electric actuator 501 causes the L-shaped plate 503 to slide. The sliding of the L-shaped plate 503 causes the fixing block 504 to slide. The sliding of the fixing block 504 causes the mounting plate 506 to slide. The sliding of the mounting plate 506 causes the anti-slip tube 507 to press against the outer wall of the material box 4. At this time, the rubber anti-slip tube 507 will be deformed under pressure. The anti-slip tube 507 increases the friction between the mounting plate 506 and the material box 4, and at the same time, it can prevent rigid compression between the mounting plate 506 and the material box 4, which could damage the material box 4. It improves the limiting effect of the mounting plate 506 on the material box 4. When the anti-slip tube 507 deforms, it squeezes... When the bending tube 508 is pressed, the "8"-shaped bending tube 508 folds together, transmitting the pressure on the anti-slip tube 507. This ensures the anti-slip tube 507 is evenly stressed, improving its performance. Made of SUS301 stainless steel, the bending tube 508 is also rust-resistant and highly elastic. When the material box 4 is not in contact with the anti-slip tube 507, it quickly returns to its original shape. Then, the electric telescopic rod 601 is activated. The extension of the output end of the electric telescopic rod 601 causes the arc plate 602 to slide. The sliding of the arc plate 602 causes the outer pressure rod 603 to slide along the surfaces of the rotating plate 606 and the adjusting plate 607. At this time, the outer pressure rod 603 presses against the rotating plate 606. 6. Adjusting plate 607 causes two rotating plates 606 to rotate towards each other along the arc of the fixed rod 605. Adjusting plate 607 rotates with rotating plate 606, causing rubber sleeve 608 to press against the side wall of the material box 4. The sliding of arc plate 602 causes limiting plate 610 to slide along the surface of clamping plate 609. At this time, clamping plate 609 restricts the sliding path of limiting plate 610, preventing rotation of limiting plate 610 and thus limiting the sliding path of arc plate 602. When the frame 1 travels on an uphill road, adjusting plate 607 supports and lifts the material box 4, preventing it from sliding downwards along the surface of the frame 1, further improving the limiting effect on the material box 4. When the frame 1 brakes suddenly during travel, the material box 4 is subjected to its own force and the force of the cargo... The inertia of the object causes it to slide closer to the control panel 2. Since the anti-slip tube 507 is in close contact with the hopper 4 at this time, the sliding of the hopper 4 causes the mounting plate 506 to slide along the surface of the friction pad 510. The friction pad 510 slows down the sliding speed of the mounting plate 506, thus buffering the hopper 4. This reduces the impact force between fragile goods and the hopper 4 when it is used to hold them. The sliding of the mounting plate 506 causes the rectangular frame 505 to slide along the surface of the fixing block 504. At this time, one spring 509 is compressed and the other spring 509 is stretched. The two springs 509 buffer the rectangular frame 505, further buffering the hopper 4.Simultaneously, the rectangular frame 505 slides along the surface of the dust baffle 513. At this time, the dust baffle 513 effectively prevents stones from falling into the rectangular frame 505, thus avoiding any impact on the normal extension or contraction of the spring 509. This ensures that the spring 509 can properly buffer the rectangular frame 505. When the rectangular frame 505 slides, the inner wall of the slot 511 also slides along the surface of the protrusion 512. At this time, the protrusion 512 restricts the sliding path of the rectangular frame 505, preventing the rectangular frame 505 from disengaging from the fixing block 504. During the movement of frame 1, the connecting plate 502, moving with the aid of the L-shaped plate 503, drives the support rod 514 to move. The movement of the support rod 514 causes the ball bearings 515 to roll along the ground. At this time, the support rod 514 and the rollers increase the contact area between frame 1 and the ground, thereby minimizing the risk of frame 1 tipping over during movement. Furthermore, the larger the size of the material box 4, the greater the extension of the output end of the electric actuator 501, and therefore the greater the distance between the two support rods 514. This allows for the adjustment of the contact area between frame 1 and the ground according to the size of the material box 4.

[0056] When it is necessary to support material boxes 4 of different sizes, rotate screw 611. Screw 611 will move upward along the inner wall of the threaded hole by means of the thread. The movement of screw 611 will drive pressure plate 612 to move. The movement of pressure plate 612 will disengage from rotating plate 606 and adjusting plate 607. Then, adjust plate 607 will slide along the inner wall of rotating plate 606, so that adjusting plate 607 can abut against the side wall of material box 4 of different sizes. After adjustment, rotate screw 611 in the opposite direction. Screw 611 will drive pressure plate 612 downward by means of the thread. When pressure plate 612 contacts rotating plate 606, pressure plate 612 will achieve the function of restricting the position of adjusting plate 607.

[0057] When protection of control panel 2 is required, the perforated plate 73 is slid downwards along the arc of the lead screw 71. The perforated plate 73 slides into the inner wall of the U-shaped plate 72, at which point the U-shaped plate 72 restricts the position of the perforated plate 73. Then, the threaded sleeve 78 is aligned with the lead screw 71 and rotated. The threaded sleeve 78 moves downwards using its threads. When the threaded sleeve 78 abuts against the surface of the perforated plate 73, it further restricts the position of the perforated plate 73. At this point, the buffer plate 75, under its own weight, will contact the positioning rod 79, which will restrict the position of the buffer plate 75. Maintaining a certain distance between the rectangular plate 76 and the control panel 2 ensures that when the frame 1 encounters an obstacle during travel, the rectangular plate 76 and the flexible wire 77 will come into contact with the obstacle. At this time, the transparent polypropylene flexible wire 77 will shield the control panel 2, minimizing the possibility of the control panel 2 being damaged by contact with the obstacle. Simultaneously, the rectangular plate 76 will bend under pressure, and the elastic steel buffer plate 75 will cushion the collision between the control panel 2 and the obstacle, minimizing the possibility of the flexible wire 77 breaking and extending the service life of the flexible wire 77.

[0058] When it is necessary to remove the material box 4, first activate the electric telescopic rod 601. The retraction of the output end of the electric telescopic rod 601 will drive the arc plate 602 to move away from the material box 4. The movement of the arc plate 602 will drive the inner pressure rod 604 to move. The movement of the inner pressure rod 604 will contact the rotating plate 606 and the adjusting plate 607. At this time, the two rotating plates 606 will rotate away from each other. The adjusting plate 607 will rotate with the rotating plate 606, causing the rubber sleeve 608 to disengage from the material box 4. Then, activate the electric push rod 501 again. The extension of the output end of the electric push rod 501 will cause the anti-slip tube 507 to disengage from the material box 4. At this time, the material box 4 can be removed.
