As a key component of a tunnel boring machine, the design, manufacturing, transportation, use, and maintenance of the conveyor have a significant impact on the entire machine.

[0003] The applicant's research revealed the following problems with conventional conveyors: 1. Different conveyor models have similar structures but differing lengths. Chutes are not fixed in length and vary in length, making them virtually incompatible across different models and resulting in poor interchangeability. 2. Once designed and manufactured, the length and angle of the conveyor cannot be quickly changed, making it inflexible and unable to quickly adapt to various operating conditions. 3. Each conveyor model, depending on the operating conditions, must be redesigned and manufactured. This small-batch, customized production of these conveyors results in high design duplication, low efficiency, and high manufacturing costs.

[0004] Therefore, it is necessary to design a modular transport aircraft in a targeted manner to reduce the duplication of transport aircraft design, reduce manufacturing costs and improve the versatility between products. Utility Model Content

[0008] Wherein, the number of the middle chutes is one or more than two.

[0009] Wherein, support plate assemblies with detachable structures are provided on the left and right sides of the outer side of the transport aircraft.
