Harvesting machine of the hopper type
HARVESTING MACHINE OF THE HOPPER TYPE (EN: tanker harvester; DE: Bunkerlader; FR: charge use à trémie; ES: cargadora de tolva; RU: бункерная уборочная машина) is the trailed machine, which is purposed for the harvesting of the milled peat, which has been gathered preliminarily into the rolls. The first models of the harvesting machine of the hopper type (UMPF) have been developed within the USSR during the start of the 1940-ies. They connect the harvesting machine of the hopper type with the tracked tractor with the engine with the power of at least 55 kilowatts. On the tracked chassis of the machine, there is situated the hopper with the scraper, with the bucket elevator, and with the movable bottom of the type of the tabular or scraper conveyor. During the working passage, the tractor with the harvesting machine of the hopper type moves along the roll, so that the roll should be located between the tracks. At the same time, the peat from the roll is gathered by the scraper, and is continuously transported by the bucket elevator into the hopper. At the end of each pass, the peat is poured from the hopper into the stockpile with the help of the movable bottom. The pivotal connection of the scraper with the frame of the machine permits to copy the relief of the surface at the deposition, which ensures the varying degree for the cleanliness during the harvesting of the peat from the roll.
With the introduction of the harvesting machine of the hopper type, there has been implemented the comprehensive mechanization for the extraction of the milled peat. Within the harvesting machines of the hopper type, which are issued within the USSR, and which are working as the trailer with the D-75 or B-75 tractors, the voluminous capacity of the hopper is up to 21 cubic metres, and the working speed is up to 10.7 kilometres per hour. Certain models of the harvesting machines of the hopper type are equipped with the automatic devices for the accounting of the peat, which has been harvested.
