Technical Field

[0001] The utility model relates to the technical field of concrete processing, and particularly relates to a feeding and discharging device for a concrete mixer truck. Background Art

[0002] Concrete mixer trucks are widely used equipment in the construction industry, mainly used for transporting and mixing concrete. Its feeding and discharging device, especially the discharging part, has a crucial impact on the operation efficiency of the concrete mixer truck and the quality of the concrete. However, in the existing feeding and discharging devices of concrete mixer trucks, the discharging pipe is often designed to be fixed and cannot adjust its discharging angle according to actual needs.

[0003] This fixed discharging pipe design has many inconveniences in practical applications. First of all, due to the fixed discharging angle, the mixer truck often needs to repeatedly adjust the position and angle of the vehicle during discharging to adapt to different discharging environments. This not only increases the complexity of operation but also reduces the discharging efficiency. Secondly, the fixed discharging pipe cannot flexibly adjust the discharging angle according to the actual situation of the discharging point, easily causing concrete spillage or accumulation, affecting the uniformity and quality of the concrete. In addition, the fixed discharging pipe may also limit the operation range of the mixer truck, making the mixer truck unable to work properly in some complex terrains or narrow spaces.

[0004] Therefore, it is necessary to improve and innovate the existing feeding and discharging device of the concrete mixer truck, especially for the design of the discharging pipe. Content of the Utility Model

At the bottom of the right side wall of the support seat, a motor is detachably provided. The output end of the motor is locked with a main shaft through a coupling. The outer wall of the main shaft penetrates through the support seat and is rotationally connected to the outer wall of the top end of the support seat through a bearing. At the top end of the main shaft, there is a connecting seat. At the top end of the connecting seat, there is a fixed seat. At the top end of the fixed seat, there is a discharging pipe.

[0008] Furthermore, the discharging pipe includes a chute, a round groove, and a cylinder. The left end of the chute is provided with a round groove. The chute and the round groove are arranged at the top end of the fixed seat. The right end of the chute is provided with a cylinder.
