[0002] The cantilever reclaimer is a high-efficiency professional reclaiming equipment used in bulk cargo ports, power plants and other material fields. Its working process is that the cantilever of the reclaimer rotates left and right to cooperate with the bucket wheel to extract the material onto the cantilever conveyor belt. The cantilever belt conveyor operates continuously to load the material onto the ground conveyor belt through the guide trough. When the arm rotates to reclaim materials, the material flow entering the guide trough moves in an arc around the center of rotation. The material drop position is not fixed. In addition, the drop height of the reclaimer hopper is large, and the material has a large lateral impact force when it falls, which can easily cause the ground belt to deviate, causing shutdown, affecting the reclaiming efficiency, and serious coal leakage, polluting the environment. In order to solve the problem of unstable drop point, the original design is to install two seasoning plates in the guide trough. Before each operation, the large machine driver cooperates with the belt patrol worker to adjust according to the field stack of the operation. The operation is risky and difficult, which is not conducive to safe production. Therefore, it is very necessary to design a device that can easily adjust the inner seasoning plate of the lower guide trough of the reclaimer to replace manual adjustment and improve operation safety and efficiency.
