Automatic loading system for screening wood shavings and intelligent screening line

An automatic loading system for screening wood shavings, comprising a material receiving and conveying mechanism, wherein a discharging side of the material receiving and conveying mechanism is connected to a feeding side of a plurality of shaving arranging and conveying mechanisms, each of the plurality of the shaving arranging and conveying mechanisms comprises a first slide-down board, a first conveying mechanism, a second slide-down board, a second conveying mechanism, a third slide-down board, and a third conveying mechanism sequentially disposed along a conveying direction of wood shavings, a width of the first slide-down board is gradually reduced along the conveying direction of the wood shavings to cause the width of the first slide-down board on a discharging side of the first slide-down board to correspond to a width of the wood shavings, the first slide-down board comprises a bottom board and material blocking boards disposed on two sides of the bottom board, and the first slide-down board is connected to a vibration motor, to enable the wood shavings to pass through a discharging end of the first slide-down board only in a posture having a length direction that is set along the conveying direction, to direct the wood shavings;

• and a baffle board is disposed above a feeding end of the second conveying mechanism, a set gap exists between a bottom end of the baffle board and a top surface of the second conveying mechanism to allow only a single wood shaving to pass through the gap between the baffle board and the second conveying mechanism, and the third slide-down board has a feeding end located below a discharging end of the second conveying mechanism at a first set distance, and a discharging end of the third slide-down board is located above a feeding end of the third conveying mechanism at a second set distance;
• a fourth conveying mechanism is disposed in front of the first conveying mechanism at a third set distance, and a top surface of the fourth conveying mechanism is higher than a top surface of the first conveying mechanism by a fourth set distance to initially spread the stacked-up wood shavings;
• and the stacked-up wood shavings are capable of being initially spread when passing through a gap between a feeding end of the fourth conveying mechanism and a discharging end of the first conveying mechanism, wood shavings located above enter the fourth conveying mechanism, and wood shavings located below fall along the second slide-down board;
• and
• a tail end of the fourth conveying mechanism is connected to the material receiving and conveying mechanism.
