Peat windrower

The three-section windrower

PEAT WINDROWER (EN: peat swath collector; DE: Torfhockenmaschine; FR: andaineur de tourbe; ES: colector de turba por ringleras; RU: валкователь торфяной) is the trailed device for the gathering of the dried milled peat from the loose layer into the windrows.

The peat windrower is moved by the tracked tractor (with the motor with the power capacity of at least 55 kilowatts). They distinguish the mechanical and pneumatic peat windrowers. There are most distributed the mechanical peat windrowers of the blade type, for which there serves as the working tool the blade (scraper), which is situated at the angle of approximately 30 degrees to the direction of the movement. During the advancing movement, the peat windrower moves the peat from the loose layer into the windrow. For the provision of the gathering of the peat with minimal losses and wetting, the blade has the sectioned structure, with the possibility for the control of the pressure onto the deposition. The peat windrowers of the blade type are manufactured either as the single-bladed and multiple-bladed devices, which are hinged onto the tractor, or as the trailing device with several working sections, each of which represents by itself two blades, which are forming the united windrow.

During the extraction of the peat, they use also the mechanical peat windrowers, for which there serves as the working tool the rotating cylindrical brush, which sweeps the dry milled peat from the surface of the deposition onto the conveyor, which is transporting the peat into the windrow. The power for all the mechanisms within the pneumatic peat windrowers is delivered from the motor of the tractor. The peat from the loose layer is sucked by the flow of the air, which is supplied into the nozzles by the fan. The aerial mixture, which has been formed within the nozzles, arrives into the cyclone-settler, from which the peat is directed onto the conveyor, and then is unloaded into the windrow.
