Description

Technical Field

[0001] The utility model relates to a container semi-trailer and belongs to the technical field of semi-trailers. Background Art

[0002] A semi-trailer is a trailer with an axle placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and there are many types of semi-trailers, such as 11-meter barn semi-trailers, 13-meter barn semi-trailers, and low-bed semi-trailers. It is a heavy-duty transportation vehicle connected to the semi-trailer head through a traction pin. Semi-trailers are mainly used to transport large and difficult-to-disassemble bulky goods, such as excavators, etc. The fence type is more suitable for pulling fresh goods, such as vegetables, fruits, etc. The box type is more suitable for pulling bulk goods and moisture-proof and more valuable goods.

[0003] A Chinese patent (publication number: CN 219487277 U) discloses an easy-to-discharge container semi-trailer, comprising a front, a chassis fixedly connected to the surface of the front, a box fixedly connected to the surface of the chassis, a hinge threadedly connected to the surface of the box, a positioning piece fixedly connected to the surface of the box door, a latch penetrating the surface of the positioning piece, a conveying mechanism disposed inside the box, and a rotating mechanism disposed on the side of the conveying mechanism;

[0004] The easy-to-unload container semi-trailer is provided with a conveying mechanism. When unloading is required, the motor is first started. The running of the motor drives the rolling shaft to start rotating, and the goods are placed on the surface of the transmission belt. At the same time, the partition on the surface of the transmission belt increases the friction of the transmission belt, making the transmission of the goods more stable, thereby completing the transmission of the goods. At the same time, the buffer plate rotates through the rotating shaft. When it rotates to the required position, the transmission belt will transmit the goods to the buffer plate, thereby unloading the goods from the box body. However, during the transportation process, the goods lack a fixing device inside the container, which makes it easy for the goods to collide with the container due to bumps inside the container, causing damage to the outer surface of the goods, and even causing damage to the goods in severe cases. In addition, at the container door in the patent, people need to manually open the door to load and unload the goods. However, when the door is heavy, it may be inconvenient to open it by manpower, so it is not convenient for people to use.

[0005] For this purpose, a container semi-trailer is proposed. Utility Model Content
