Abstract

PNEUMATIC VEGATABLE MILLING PEAT, including a frame with rollers, mounted on the frame a cyclone-precipitator with a housing, bottom and suction nozzles and a fan inside the housing, characterized by the fact that the slope of the transport and made porous, while the cyclone precipitator is equipped with valves located under the porous bottom and pivotally mounted on the housing with the possibility of rotation and located inside the building usa in the zone of the porous bottom with sludge paddles.

Description

The invention relates to peat machinery, and, in particular, to pneumatic rolls. The purpose of the invention is to reduce the energy intensity of the peat transport process. FIG. 1 shows a rake, side view; in fig. 2 is a diagram of unloading of a swather; in fig. 3 is a section A-A in FIG. 2j in FIG. 4 is a section BB in FIG. 2. Pneumatic rake contains frame 1 with rollers 2, cyclone precipitator 3 located on frame 1 along its entire length, with fan 4 and inclined porous transporting bottom 5, with hinged valves 6, which are spread inside the cyclone - precipitator 3 at an angle of about 90 (to avoid peat hanging), precipitator vanes 7 and suction nozzles 8. The rake works as follows. During the forward movement along the peat field of the nozzle 8, the peat is sucked into the cyclone precipitator 3 due to the discharge created by the fan 4 built in the cyclone precipitator 3. Due to the discharge in the cyclone precipitator 3 through the porous transporting bottom 5 into the cyclone precipitator 3 some (5-10%) amount of atmospheric air enters, which aerates the layer of milling chips released in the cyclone precipitator 3, and informs it of flow in the direction of the slope of the porous transporting bottom 5. The peat is discharged into the shaft version The precipitator vanes 7, which impede the free movement of peat particles over the porous transporting bottom 5, promotes better separation of peat from the air mixture and exclude the possibility of some entrainment of particles by the upward flow. The control flaps 6 allow changing the resistance of the porous transporting bottom 5, since for normal operation of the machine it is necessary to have equal resistance of the parallel sections of the pneumatic system: a nozzle - a cyclone and a porous bottom with peat.
