The invention provides a dredging type
silt cleaning device. The dredging type
silt cleaning device comprises a ship body, a lifting
conveyor belt, a dredging mechanism and a
transfer mechanism; the dredging mechanism comprises supporting rods, a sliding block, a sleeve, a lead screw, a connecting shaft, a
shovel plate, torsional springs, a big gear, a small gear and a motor; the sliding block isinstalled on the ship body through the supporting rods; one end of the lead screw is installed on the ship body, the other end of the lead screw penetrates through the sleeve and the sliding block, and the lead screw is in power connection with the motor; the
shovel plate is rotatably installed on the sliding block through the connecting shaft; and the
transfer mechanism is fixedly installed on the ship body. The rotation movement between the lead screw and the sleeve is transformed into linear movement, and then the
shovel plate is pushed to dredge
silt; the shovel plate can rotate around thesliding block, and then the shovel plate is folded when the shovel plate move towards a silt stack; the shovel plate is prevented from generating counter-acting force by being in contact with the silt stack, and then it is ensured that the ship body cannot tempestuously waggle when dredging is carried out; and the silt is automatically transported outside of the ship body through the
transfer mechanism, and the dredged silt is prevented from being transferred through manual work.
