Description

Technical Field

[0001] This utility model relates to the technical field of semi-trailers for transporting powder materials, specifically a lower outlet structure for a semi-trailer for transporting medium-density powder materials. Background Technology

[0002] Currently, the main type of specialized vehicle used for bulk transportation of powdery materials on the market is the horizontal tank truck, while the semi-trailer is the most practical means of transportation for medium and short-distance bulk powdery materials transportation.

[0003] A search revealed that the application "A Lower Outlet Structure for a Medium-Density Powder Material Transport Semi-Trailer" with application number "202123054428.9" utilizes a drive mechanism, a spiral feed rod, a three-way air inlet valve, and two U-shaped auxiliary blowing pipes. When the drive motor is activated, the drive shaft rotates, which in turn drives the first bevel gear. Since the first and second bevel gears mesh, they in turn drive the rotating rod, thus rotating the spiral feed rod. This rotation forces the powder in the transport tank to be transported into the L-shaped discharge pipe, ensuring stable transport, preventing blockages, and increasing the powder density in the L-shaped discharge pipe, thereby improving unloading efficiency. Then, one end of the three-way air inlet valve is connected to an external air pump, injecting airflow into the two U-shaped auxiliary blowing pipes. The airflow is blown into the L-shaped discharge pipe from the two U-shaped auxiliary blowing pipes, forming an airflow along the discharge direction of the L-shaped discharge pipe. The powder follows the airflow and is automatically discharged from the L-shaped discharge pipe through the discharge valve.

[0004] Although a three-way air inlet valve and two U-shaped auxiliary blowing pipes are used to assist in pushing the powder particles, the narrow internal space of the pipe makes it easy for rotating airflow to be generated, causing the powder particles to flow back into the U-shaped auxiliary blowing pipes and cause blockage. Once the U-shaped auxiliary blowing pipes are blocked, they cannot complete the pushing, which leads to poor material discharge. Moreover, the three-way air inlet valve and the two U-shaped auxiliary blowing pipes are fixed on the outer wall of the L-shaped discharge pipe, which is a whole, making maintenance more difficult.

[0005] The purpose of this utility model is to provide a lower outlet structure for a semi-trailer transporting medium-density powder materials. The discharge pipe adopts a three-section design. The middle section uses a reversing device to transmit the rotation of the input shaft to the output shaft. Moreover, the lower pipe is inclined, which allows the upper and lower spiral blades to transport materials stably for a long time, greatly improving the discharge efficiency and stability of powder materials. The structure is simpler and the operation is more convenient.

[0006] To achieve the above objectives, a lower outlet structure for a medium-density powder material transport semi-trailer is provided, comprising: a discharge assembly, which includes an upper pipe, a middle pipe, a lower pipe, an input shaft, an upper spiral blade, a protective cover, a commutator, an output shaft, and a lower spiral blade.

[0008] According to the aforementioned lower outlet structure of a semi-trailer for transporting medium-density powder materials, the lower pipe forms a 15-degree angle with the horizontal line, facilitating powder discharge.

[0009] According to the lower outlet structure of a semi-trailer for transporting medium-density powder materials, the input shaft passes through a protective cover, a commutator, and a central pipe, and is fixedly connected to the output end of the main motor. When the main motor is started, the input shaft can rotate, and the output shaft can be rotated through the commutator, facilitating the discharge of powder materials.

[0010] According to the lower outlet structure of a medium-density powder material transport semi-trailer, the top of the bracket and the upper pipe are both fixedly connected to the storage tank of the transport semi-trailer.
