Description

Technical Field

[0001] This utility model relates to the field of dump truck technology, specifically to a rear-tipping dump truck cargo box. Background Technology

[0002] Dump trucks are a type of cargo truck equipped with an automatic tipping device in the cargo compartment. Also known as tipper trucks, they consist of a chassis, hydraulic lifting mechanism, cargo box, and power take-off (PTO). In civil engineering, dump trucks are frequently used in conjunction with excavators, loaders, belt conveyors, and other construction machinery to form loading, transporting, and unloading production lines for earthwork, sand, gravel, and bulk materials. Dump truck cargo boxes are available in two types: rear-tipping and side-tipping. The movement of a piston rod is controlled by a control system; rear-tipping is more common, as it involves pushing the piston rod to tip the cargo box.

[0003] As disclosed in CN219806743U, a rear-tipping self-unloading cargo box includes: a cargo box and a frame; a first chute, which is located inside one side of the bottom of the cargo box, and has a snap-fit ​​groove on the top of its inner side; a second chute, which is located inside one side of the top of the frame, and has several second rotating seats fixedly installed on the bottom of its inner side, with a connecting rod rotatably connected to the inner side of each second rotating seat; and a snap-fit ​​plate. This utility model provides a rear-tipping self-unloading cargo box. Through the cooperation of the cargo box, first chute, snap-fit ​​groove, snap-fit ​​plate, first rotating seat, hydraulic rod, hydraulic cylinder, frame, second chute, second rotating seat, and connecting rod, the cargo box can be side-lifted for unloading during use, reducing the space occupied inside the cargo box and increasing the cargo loading capacity.

[0004] However, in the existing technology CN219806743U, a rear-tipping self-unloading freight box, if it is used to transport gravel and sand, will leave some unloaded goods in the compartment when unloading, which makes it less practical. Summary of the Invention

[0005] The purpose of this utility model is to provide a rear-tipping self-unloading cargo box to solve the problem mentioned in the background art that when transporting goods such as crushed stone and gravel, some unloaded goods will remain in the cargo box during unloading, resulting in poor practicality.

[0006] To achieve the above objectives, this utility model provides a rear-tipping self-unloading cargo container.

[0007] The vehicle includes a carriage, the top of which is fixedly connected to a roof plate. One end of the roof plate has a transverse sliding groove, and the interior of the transverse sliding groove has a symmetrical first sliding groove. At the end away from the transverse sliding groove, a longitudinal sliding groove is formed, and the interior of the longitudinal sliding groove has a symmetrical second sliding groove. A servo motor is fixedly connected to the top of the roof plate, and a connecting rod is fixedly connected to the output end of the servo motor. A push plate is movably connected inside the transverse and longitudinal sliding grooves. A scraper is fixedly connected to the bottom end of the push plate, and symmetrical recessed handles are formed at both ends of the push plate.

[0008] The first cargo box door is movably connected to one end of the carriage. The two ends of the first cargo box door are fixedly connected to symmetrical first buckles. A first rotating pin is fixedly connected to the end away from the first buckle. By setting the first cargo box door, the first buckle and the first rotating pin, the operator can open the first cargo box door by rotating the first rotating pin to make it disengage from the first buckle, thereby achieving the purpose of opening and closing the first cargo box door. The second cargo door is movably connected to both ends away from the first cargo door. The two ends of the second cargo door are fixedly connected to symmetrical second buckles, and the end away from the second buckle is fixedly connected to a second rotating pin. By setting the second cargo door, the second buckle and the second rotating pin, the operator can open the second cargo door by rotating the second rotating pin to make it disengage from the second buckle, thereby achieving the purpose of opening and closing the second cargo door. The bottom of the carriage is fixedly connected to a stabilizing hydraulic rod, and a symmetrical first hydraulic cylinder is fixedly connected to the end away from the stabilizing hydraulic rod. The first hydraulic cylinder is movably connected to a first hydraulic rod, and the top of the first hydraulic rod is fixedly connected to a first U-shaped plate. Several first rotating rods are movably connected to the inside of the first U-shaped plate. The first rotating rods and the first sleeve plate are sleeved together. By setting up the first hydraulic cylinder, the first hydraulic rod, the first U-shaped plate, the first rotating rods and the first sleeve plate, the operator can activate the first hydraulic cylinder on the left or the first hydraulic cylinder on the right according to the unloading surface, so that the carriage tilts to transport the goods, thereby achieving the purpose of unloading from the side. A second hydraulic cylinder is fixedly connected to the end away from the first hydraulic cylinder. A second hydraulic rod is movably connected inside the second hydraulic cylinder. A second U-shaped plate is fixedly connected to the top of the second hydraulic rod. Several second rotating rods are movably connected inside the second U-shaped plate. The second rotating rods and the second sleeve plate are sleeved together. By setting up the second hydraulic cylinder, the second hydraulic rod moves upward. As the second hydraulic rod moves, the second rotating rods in the second U-shaped plate cause the second sleeve plate to begin to slide stably in the second U-shaped plate. Finally, the carriage tilts to transport the goods, thereby achieving the purpose of unloading towards the rear of the vehicle. The bottom end of the stabilizing hydraulic rod is fixedly connected to a mounting base, and the two ends of the mounting base are fixedly connected to mounting plates. The top of the mounting plate has several mounting holes, and the mounting holes are movably connected to fixing bolts. By setting up the mounting plate, mounting holes and fixing bolts, the workers install the fixing bolts into the mounting holes and install the carriage on the vehicle body through the mounting plate, thereby achieving the purpose of fixing the carriage. The servo motor, the first hydraulic cylinder, and the second hydraulic cylinder are electrically connected to the controller. The top of the controller is movably connected to a start button and a control button. By setting the controller, the start button, and the control button, the operator can start and control the servo motor, the first hydraulic cylinder, and the second hydraulic cylinder, thereby achieving the purpose of starting and controlling the servo motor, the first hydraulic cylinder, and the second hydraulic cylinder.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This type of rear-tipping self-unloading cargo container, by setting up transverse chutes, longitudinal chutes, a servo motor, a push plate, and a scraper, allows the following: After unloading at the rear of the vehicle, due to inertia, the push plate, carrying the scraper, moves towards the first cargo door in the transverse chutes to push out any remaining goods from the cargo compartment. After unloading from the side, when the push plate slides to the position of the connecting rod, a small telescopic mechanism in the connecting rod connects the connecting rod and the push plate. The operator starts and controls the servo motor using the start and control buttons on the controller. The servo motor drives the push plate to rotate, causing it to enter the longitudinal chutes. After adjustment, the push plate and the connecting rod separate. Due to inertia, the push plate, carrying the scraper, moves towards the second cargo door in the longitudinal chutes to push out any remaining goods from the cargo compartment, thus improving the practicality of the device.

[0010] This rear-tipping self-unloading cargo box features a first and a second hydraulic cylinder. Workers can choose to open the first and second cargo box doors based on the unloading angle. For rearward unloading, workers open the first cargo box door by rotating the first rotating pin to disengage it from the first latch. Then, the second hydraulic cylinder is activated using the start and control buttons on the controller. This causes the second hydraulic rod to move upwards. As the rod moves, the second rotating rod in the second U-shaped plate causes the second sleeve plate to slide stably within the U-shaped plate, ultimately tilting the cargo box to transport the goods. For side unloading, workers activate either the left or right first hydraulic cylinder based on the unloading surface. Rotating the second rotating pin disengages it from the second latch to open the second cargo box door. This flexibility allows for selection of the unloading direction based on the specific situation. Attached Figure Description

[0015] Example 1: After the goods are unloaded, when the push plate 9 slides to the position of the connecting rod 8, the small telescopic mechanism in the connecting rod 8 connects the connecting rod 8 and the push plate 9. The operator starts and controls the servo motor 7 through the start button 34 and control button 35 on the controller 33. The servo motor 7 drives the push plate 9 to start rotating, so that it enters the longitudinal slide 5. After adjustment, the push plate 9 and the connecting rod 8 separate. Due to inertia, the push plate 9, along with the scraper 10, moves towards the second cargo door 15 in the longitudinal slide 5 to push the remaining goods in the carriage 1 out of the carriage 1.

[0016] Example 2: When there is not enough time to start the servo motor 7, the operator can adjust the angle of the push plate 9 by using the recessed handle 11 on the push plate 9.

[0017] In this embodiment, a rear-tipping self-unloading cargo box is used by the operator who installs the fixing bolts 32 into the mounting holes 31 and installs the cargo box 1 onto the vehicle body via the mounting plate 30.

Upon arrival at the designated location, the operator selects to open the first cargo box door 12 and the second cargo box door 15 according to the unloading angle. If unloading is done towards the rear of the vehicle, the operator opens the first cargo box door 12 by rotating the first rotating pin 14 to disengage it from the first latch 13. Then, the operator activates the second hydraulic cylinder 24 via the start button 34 and control button 35 on the controller 33. The second hydraulic cylinder 24 causes the second hydraulic rod 25 to move upward. As the second hydraulic rod 25 moves, the second rotating rod 27 in the second U-shaped plate 26 causes the second sleeve plate 28 to begin sliding stably within the second U-shaped plate 26. Finally, the cargo box 1 tilts to transport the cargo and unload it. At that time, due to inertia, the push plate 9, along with the scraper 10, moves towards the first cargo door 12 in the transverse chute 3 to push out the remaining goods in the cargo compartment 1. When unloading from the side, the staff activates the first hydraulic cylinder 19 on the left or right side according to the unloading surface. By rotating the second rotating pin 17 to disengage it from the second latch 16, the second cargo door 15 is opened. After the goods are unloaded, when the push plate 9 slides to the position of the connecting rod 8, the small telescopic mechanism in the connecting rod 8 connects the connecting rod 8 and the push plate 9. The staff starts and controls the servo motor 7 through the start button 34 and control button 35 on the controller 33. The servo motor 7 drives the push plate 9 to start rotating, so that it enters the longitudinal chute 5. After adjustment, the push plate 9 and the connecting rod 8 separate. Due to inertia, the push plate 9, along with the scraper 10, moves towards the second cargo door 15 in the longitudinal chute 5 to push out the remaining goods in the cargo compartment 1.
