Concrete discharging device for building construction

The invention discloses a building construction concrete discharging device which comprises a base, a discharging mechanism and a power mechanism, steering wheels and walking wheels are arranged below the base, a temporary storage cavity is formed in the base, a stock bin is arranged above the base, the stock bin is connected with the temporary storage cavity through a discharging pipe, and the discharging mechanism comprises a main shaft, a rotating ring and a hanging box. The device has the beneficial effects that the power mechanism drives the axle and the main shaft to rotate, the axle drives the walking wheels to rotate when rotating, so that the device walks along a paving path, the paving efficiency is improved, and the paving efficiency is improved. When the main shaft rotates, the first conveying cylinder and the second conveying cylinder are driven to rotate, so that discharging is carried out in a circular range, automatic discharging and device walking are achieved, efficiency is improved, labor i
