[0002] The mixing truck, also known as a concrete mixing truck, is a special vehicle widely used in the construction of buildings, roads, bridges and urban infrastructure, and is mainly used for mixing concrete raw materials during transportation to ensure the uniformity and fluidity of concrete when it reaches the construction site.

[0003] Most of the mixing trucks on the market are divided into two categories. One is mainly used to hold mixed concrete and continues to mix during transportation to prevent the concrete from solidifying. The other type can actively add concrete raw materials to the corresponding mixing tank during movement through the corresponding feeding assembly and then mix and prepare.

[0004] However, most self-feeding mixing truck devices rely on external feeding machines such as common screw feeders and scraper feeders for feeding, and the vehicle must also move synchronously with the movement of the feeding machine during the feeding process. The lack of convenient feeding components in the vehicle itself limits the convenience of the vehicle and makes it difficult to achieve more convenient and automatic feeding during vehicle movement. In view of this, we propose a self-feeding flat mouth mixing truck device. UTILITY MODEL CONTENTS
