Tar felt laydown machine, including the frame, the malthoid is carried and is laid the mechanism, control and running gear, the malthoid is laid in the frame back upper place, and malthoid conveying mechanism includes and leads the felt board, leads the felt board down that the slope middle part in the frame is established to the feeding wheel, leads the felt bars and establishes front end in the frame and receive membrane wheel ann on, in the malthoid below, receives the membrane wheel down at the frame middle part, and the part is laid to main dynamic wheel group and the auxiliary wheel component malthoid of forward portion under the frame, is driven main dynamic wheel group through reduction gear group by the motor in the frame, the hopper is established in the frame front upper place, is equipped with oleamen electrical heating and agitating unit in the hopper, flame utensil location middle part after the frame, the control panel is adjacent with the regulation handle in the frame back upper place, be equipped with front wheel, back universal wheel constitution running gear around the frame bottom respectively. The utility model discloses but greatly reduced workman intensity of labour improves the efficiency of construction, and with low costs, material loss is few, produces smog, dust when avoiding the oleamen heating, the non -staining environment, and the equipment investment is little, convenient operation.
