Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of self-dumping semi-trailers, specifically a rear-tipping container self-dumping semi-trailer. Background Technology
[0002] The dump semi-trailer uses a hydraulic system to drive the cargo box for autonomous unloading, mainly including two operating modes: side tipping and rear tipping. Its cargo box is made using manganese plate welding technology and equipped with a non-independent steel plate stamping rigid suspension system, enabling it to complete the unloading of bulk materials such as sand, gravel, and coal within 30 seconds to 2 minutes, with a lower residue rate than traditional models.
[0003] Existing equipment has a complex structure and high cost. Furthermore, when goods are stored inside the container, the falling of the container will generate significant pressure, which may damage the structure. Therefore, a rear-tipping container self-unloading semi-trailer is proposed. Summary of the Invention
[0004] The purpose of this utility model is to provide a rear-tipping container self-unloading semi-trailer to solve the problems mentioned in the background art, such as the complex structure and high cost of existing devices, and the large pressure generated when goods are stored inside the container, which may damage the device structure.
[0005] To achieve the above objectives, this utility model provides a rear-tipping container self-unloading semi-trailer.
[0006] The system includes a base plate, a self-unloading mechanism fixedly mounted on the top of the base plate, a connecting member, a container fixedly mounted on the top of one side of the base plate, an assembly shell fixedly mounted inside the container, a hydraulic actuator fixedly mounted at the bottom of the assembly shell, a rotating shaft fixedly mounted at the bottom of the hydraulic actuator, a splicing member movably mounted on the outside of the rotating shaft, an electromagnetic slide groove fixedly mounted on the top of the base plate, a slider movably mounted inside the electromagnetic slide groove, the top of the slider fixedly connected to the splicing member, and a buffer mechanism fixedly mounted on the top of the base plate. The buffer mechanism includes a slot. The top of the bottom plate has a slot, and several buffer springs are fixedly installed inside the slot. A buffer plate is fixedly installed at the top of each buffer spring, and a damper is fixedly installed at the bottom of the buffer plate. A rubber ball is fixedly installed at the top of the buffer plate. By opening a slot at the top of the bottom plate, welding multiple buffer springs inside the slot, and welding a buffer plate together at the top of the buffer springs, a damper is installed at the bottom of the buffer plate, and multiple rubber balls are glued to the top of the buffer plate. When one end of the container falls, a certain pressure will be generated, which may damage the bottom plate or the cargo inside. When the container falls, it will act on the buffer plate. The buffer springs and damper are installed at the bottom of the buffer plate. Through action and reaction, the force generated when the container falls is buffered. The bottom end of the base plate is fixedly provided with several wheel frames, and wheels are movably installed inside the wheel frames. By providing multiple wheel frames at the bottom end of the base plate and installing wheels inside the wheel frames, the normal movement of the device can be ensured. The container is equipped with a hinge on one side and a door on the other side of the hinge. By installing a hinge on one side of the container and a door on the other side of the hinge, it can be ensured that the goods inside the container will not fall out. The container has a buckle fixedly installed on one side, and a locking bar is fixedly installed inside the buckle. By installing a buckle on one side of the container and a locking bar inside the buckle, the container door can be fixed during cargo transportation to ensure that the container door cannot be opened. A control switch is fixedly installed on one side of the base plate. The control switch is electrically connected to the hydraulic device. By installing the control switch on one side of the base plate, the control switch can be used to control the operation of the hydraulic device.
[0007] Compared with the prior art, the beneficial effects of this utility model are: 1. This type of rear-tipping container self-unloading semi-trailer has a connecting piece installed at the top of one side of the bottom plate, a container installed at the top of the connecting piece, an assembly shell welded inside the container, a hydraulic device installed at the bottom of the assembly shell, a rotating shaft at the bottom of the hydraulic device, a splicing piece movably installed on the outside of the rotating shaft, and an electromagnetic slide rail installed at the top of the bottom plate, with a slider movably installed inside the electromagnetic slide rail. When unloading goods inside the container, the hydraulic device is activated to lift the container, and then the electromagnetic slide rail is activated to move the slider to a suitable position to adapt to the change of fulcrum due to the change of the hydraulic device's position, thereby ensuring the normal operation of the device.
[0008] 2. This type of rear-tipping container self-unloading semi-trailer has a slot at the top of the bottom plate, with multiple buffer springs welded inside the slot. The tops of the buffer springs are welded together to a buffer plate, and a damper is installed at the bottom of the buffer plate. Multiple small rubber balls are glued to the top of the buffer plate. When one end of the container falls, a certain pressure is generated, which may damage the bottom plate or the cargo inside. When the container falls, it will act on the buffer plate. The buffer springs and dampers at the bottom of the buffer plate, through action and reaction, will buffer the force generated when the container falls. Attached Figure Description
