Discharging device used for waste timber

The invention relates to a timber conveying device, in particular to a discharging device used for waste timber. The discharging device comprises a machine frame, a motor, a control device and a conveying device. The conveying device comprises a discharging box, an upper throwing roller and a lower throwing roller are arranged inside the discharging box, a transmission gear is fixedly connected to the lower throwing roller coaxially and connected with a motor in a chain transmission mode, and space where the timber can pass is formed between the upper throwing roller and the lower throwing roller. The control device comprises a pressing shaft, a cam mechanism and a control pressing plate, the pressing shaft penetrates through the discharging box and is connected to the surface of the upper throwing roller, one end of the control pressing plate is fixedly connected to the pressing shaft, a linkage plate is vertically hinged to the other end of the control pressing plate and connected with the cam mechanism, and a reset spring is connected between the control pressing plate and the machine frame. By means of the discharging device, the problems that in the existing conveying process of the waste timber, efficiency is low, and time and labor are wasted are solved.
