As a labor-saving and efficient means of transportation, automobiles have been widely used all over the world. Trucks are commercial vehicles designed and equipped mainly for carrying goods. In order to improve loading efficiency and reduce labor costs, people gradually adopt automatic vehicles. Unloading is used to load, unload and transport goods. Most of the current dump trucks use a single lifting mechanism to jack up the carriage, so that the carriage forms a tilted state of high front and low rear, high left and low right, or high right and low left, so that the goods can be placed on the other side. The self-weight slides along the inclined bottom surface of the carriage and is unloaded from the unloading door. Usually, the cargo capacity of the car reaches several tons or even dozens of tons. The lifting mechanism needs to have sufficient lifting force and also need to maintain sufficient stability. In addition, when the truck is unloading, it is necessary to open the tailgate of the tipping bucket. In the prior art, it is usually opened manually, which is time-consuming and laborious; This tail plate installation structure is difficult to ensure the airtightness around the tipping bucket, especially for small goods such as muck and stones, which are easy to spill.

When it needs to be disassembled, you only need to pull the fastener to make it swing away from the clamp, and the locking can be quickly and conveniently released.

In the above automatic unloading vehicle, the power of the first hydraulic cylinder is greater than the power of the second hydraulic cylinder. Preferably, the power of the first hydraulic cylinder is three to five times that of the second hydraulic cylinder. During the unloading process of the hopper, the hydraulic cylinder together acts as the main thrust and bears the gravity of the hopper and the goods in the hopper. The second hydraulic cylinder pushes the connecting plate to change the direction of the connecting plate, so that the connecting plate is always facing the hopper, so that the hydraulic cylinder one is highly efficient. The force applied to the hopper realizes the inclined discharge of the hopper.

In the above-mentioned automatic unloading vehicle, the lower side of the tailgate is hinged on the bottom plate of the hopper; the frame has a hinged seat hinged with the bottom of the hopper, and the hinged seat is connected with A push rod capable of rotating the tailgate around the hinge point of the tailgate. The lower end of the tailgate is hinged on the hopper, so it will not fall off, and there will be no large gap between the tailgate and the bottom plate of the hopper, which can effectively prevent the goods from falling. , The hopper rotates around the hinged seat, and the push rod on the hinged seat can push the tailgate to rotate around the hinge point of the tailgate, so as to open the tailgate and realize unloading conveniently and quickly.

Compared with prior art, the utility model has the following advantages:

1. In the utility model, the connecting plate moves along the arc track of the mounting seat at the bottom of the hopper to ensure that the connecting plate is always facing the bottom plate of the hopper, and the hydraulic cylinder can exert effective thrust on the bottom plate of the hopper.
