[0002] With the implementation of infrastructure projects such as highways, water conservancy, and railways, a large number of construction excavations have emerged, resulting in a large number of exposed soil slopes and rock slopes, changing the original landform and stress state, altering the stability of some slopes, damaging the original ecosystem, and leading to serious problems of soil erosion and environmental ecological imbalance. To ensure the stability of slopes, corresponding slope protection projects need to be built to prevent hazards such as collapse and scouring of slopes of related projects, thereby protecting the normal use of the main project. Currently, slope protection bricks are usually used for slope protection, and slope protection bricks play a role in preventing soil erosion. In the prior art, slope protection bricks are mainly hexagonal slope protection bricks. The preparation process of hexagonal slope protection bricks usually includes two processes: casting and demolding.

[0003] For example, the patent with the application number CN202410772817.4 discloses a slope protection brick demolding production line, which includes a first roller conveyor, a turning structure, a vibrating conveyor structure, and a second roller conveyor arranged in sequence along the conveying direction of the production line; a feeding structure is arranged at one end of the first roller conveyor away from the turning structure; the turning structure is arranged at the end of the first roller conveyor along the conveying direction of the first roller conveyor, and the turning structure is used to turn the mold with an upward opening and the slope protection brick inside to a state with a downward opening and then move it to the subsequent vibrating conveyor structure; a picking structure is arranged at one end of the vibrating conveyor structure close to the second roller conveyor, and the picking structure straddles the vibrating conveyor structure; the second roller conveyor is arranged at the end of the vibrating conveyor structure along the conveying direction of the vibrating conveyor structure, and a stacking structure is arranged at one end of the second roller conveyor away from the vibrating conveyor structure. The turning mechanism includes a base and a circular ring seat rotatably arranged on the base. A pair of circular ring seats are symmetrically arranged, and a plurality of support rods are evenly distributed between the two circular ring seats along the axis of the circular ring seat. A driving component is arranged at the lower end of the circular ring seat; two clamping units with the same structure and symmetrically arranged are arranged between the plurality of support rods. Each clamping unit includes a first belt conveyor and a third roller conveyor arranged in parallel at intervals. A first oil cylinder for driving the first belt conveyor to approach or move away from the third roller conveyor is arranged on the circular ring seat. The telescopic rod of the first oil cylinder is hinged to the corresponding first belt conveyor, and one end of the cylinder body of the first oil cylinder is hinged to the circular ring seat; four first oil cylinders are arranged on the circular ring seat in each clamping unit.

[0004] The structure of the aforementioned turning mechanism is relatively complex and requires a large space. Summary of the Utility Model
