Heavy Duty Rotary Tiller Working parts

In the use of the rotary tiller, the blade is the main working parts, but also relatively easy to damage the parts.

Blade, also known as the plow knife, knife teeth, is fixed with a bolt on the knife seat, the knife is arranged in a spiral line, usually welded on the knife shaft, with the knife shaft rotation. Common chopped soil mattress effect of the blade has chisel and "L" type two. The former front edge of the narrow, was flat mouth or pointed type, with good ability to enter the soil. In the excavation of the soil when the required power is small, but there will be grass around the grass, more suitable for grass-free loose soil and farming on the ground. The latter blade by the side cutting edge and cutting edge of the two parts, very sharp, side cutting blade is generally two straight and arc, in the soil, also has a certain support side of the role of pressure. Commonly common L-type has a right-angle knife, swamp knife and machete several.

Straight angle knife stiffness, blade wide, generally used for farming soft ripe, width is larger than other knives, are generally fixed with a bolt in the cutter with a cutter blade, the side cutting edge and cutting edge by the Straight line composition. Swamp knife is used for swamps and grass, because the main used to cut off the plant roots, so the blade width, good stiffness, is very practical. Rotary blade is the main part of the equipment work, side by side distribution, as if many small hoe teeth installed in the spiral on the horizontal axis, the axis of the axle and the tractor axle parallel, by the tractor power output shaft by universal joints, gearbox drive Rotate. The blade rotates from the ground to cut the soil from above and below. As the tractor moves forward, the rotating blade is cut into the soil without cutting, and the cut soil is dropped to the rear and collided with the shell and the carriage. And then fell to the ground, and finally by the carriage flattened. And thus broken soil full, ground leveling.

Cut the clods for the wedge-shaped, longitudinal section perpendicular to the machine forward looking at the crescent-shaped. The reason for this is because the blade rotates with the arbor at the same time, but also follow the tractor forward synthetic motion results.

Crescent contours are the trajectories of the blade tip synthesis, and the speed of the blade rotation and the speed of the tractor forwards determine the size of the clod. Numerous examples show that the blade speed is large, the forward speed is small, the soil block is small; blade speed is small, the forward speed is large, the clods are coarse. Therefore, before the farming must be based on the requirements of the ground to choose the appropriate blade speed and forward speed.
