However, for powder and granular materials with coarse particles, high specific gravity, high water content and poor fluidization performance, ordinary horizontal powder and granular material vehicles cannot achieve the expected purpose. For example, lime powder and iron powder must be loaded, transported and unloaded with lifting powder and granular material transport vehicles.

[0003] However, when the carriage of the existing powder and particle material transport semi-trailer is lifted, the lifting is mostly carried out by a hydraulic device. However, when the hydraulic device is lifted, the hydraulic device is mostly fixed, which limits the angle or height adjustment range of the carriage during lifting, affecting the adaptability and unloading efficiency under different working conditions. When the entire vehicle is stagnant on an uneven ground, it will affect the smooth lifting of the carriage and even cause the vehicle to overturn. Therefore, it is necessary to propose a new carriage lifting structure for the powder and particle material transport semi-trailer. Utility Model Content

[0025] In this embodiment, the base support seat 101 is installed on the top of the chassis of the semi-trailer through the mounting member 104, and two sets of slide grooves 102 are set on the surface of the base support seat 101 for installing and guiding the slide column 103. When the car body needs to be lifted, the hydraulic cylinder 108 is started, and the hydraulic cylinder 108 is used to push the push rod 109, so that the push rod 109 synchronously drives the lifting component 3 to slide outside the slide column 103.
