The use method of the shuttle unloading device capable of controlling the lifting angle for the building is characterized in that the shuttle unloading device capable of controlling the lifting angle for the building is the shuttle unloading device according to claim 4, and the use method comprises the following steps:
s1, after a shuttle car for construction reaches a discharging position, when stones around a stone field are accumulated and cannot be discharged, lifting motors of lifting devices on a left baffle plate and a right baffle plate drive lifting spoons on a lifting chain to operate, the lifting spoons in a retracted state are pressed to be in a horizontal state through the weight of the stones, the stones in the shuttle car are conveyed out of the shuttle car through the lifting chain, and after the stones are lifted to the upper end of the shuttle car through the lifting spoons, the stones are ejected out of the shuttle car through the elasticity of a spring rotating shaft, so that the stones around the stone field can be discharged in a long distance, and the problem of accumulation of the stones around the stone field is solved;
s2, when residual stones cannot be lifted after being lifted by the lifting device, starting the lifting button, lifting the first lifting rod and the second lifting rod in the lower right direction of the shuttle car main body to form a left inclined state, accelerating stone unloading, pressing the reset button after stone unloading is finished, rotating the potentiometer, accelerating resetting of the hydraulic device and the lifting device, and completing automatic unloading operation;
s3, in the unloading process, stones at the unloading position are piled up and can not be unloaded again, lifting of different inclination angles can be completed by respectively adjusting lifting heights of the first lifting rod and the second lifting rod according to different positions, the unloading direction of the shuttle car is adjusted to be the right side for unloading, the unloading work of different positions is completed, and the unloading work of different positions can be adjusted according to requirements.
