Rollover-preventing self-unloading semitrailer

Technical Field

The utility model relates to the technical field of dump semi-trailers, in particular to an anti-rollover dump semi-trailer.

Background

The semitrailer is a trailer with an axle arranged behind the center of gravity of the vehicle and provided with a connecting device capable of transmitting horizontal and vertical forces to the tractor, and is generally a three-axle semitrailer, the types of the semitrailer are classified into eleven-meter-bin semitrailer, thirteen-meter-bin semitrailer, low-bed semitrailer and the like, the self-unloading semitrailer is a common type of semitrailer, and the light and medium-sized common self-unloading trailer for highway transportation mainly bears loose goods such as sand, soil, coal and the like for transportation and is usually matched with a loader for use.

When the existing self-discharging semitrailer is used, some problems still exist:

1. when the semitrailer is unloaded, as the semitrailer is laterally unloaded, the soil is easy to adhere to one side of the tilted carriage due to the viscosity of the soil when the soil is unloaded, so that the phenomenon of side turning of the vehicle is caused because the soil falls into the carriage on the other side when the soil of the tilted carriage falls.

2. When the existing semitrailer is used for side unloading, the baffle plate is extruded by gravity of goods to perform side unloading, and finally, a small part of goods are extruded by gravity to prevent the baffle plate from being opened, so that a small part of goods remain in a carriage.

Therefore, we propose a rollover-preventing self-unloading semitrailer for solving the above problems.
