Description
ne между рабочими ножами установпены аопопнитепьные ножи 7, выт нутые и иаогнутыв по спирали в направпеик. всась|ваемо го потока гидросмеси. Ножи 7 выполнены /Ьо- рочеины ми по сравнению с ножами 3 и не доход т до их рабочей зоны, не дьэдава в этой области допоп итепьных сопротивлений. Внутренние кромки ножей 7 заточены, по форме|ЭКрана 2. Таким образом, между кромками ножей 7 и кромкой отверсти всасывающей трубы 1 образуетс равномерный по ширине иамельчитепьный зазор.ne between the working knives are installed aopopnite knives 7, elongated and bent in a spiral in a directional key. suction of the slurry stream. The knives 7 are made / crocheted compared to the knives 3 and do not reach their working area, not in this area of additional resistance. The inner edges of the knives 7 are sharpened in the shape of | Screen 2. Thus, a uniform width and a thin gap is formed between the edges of the knives 7 and the edge of the opening of the suction pipe 1.
Ножи 3 также изогнуты по спирапи и изнутри могут иметь режущую кромку, по форме соответствующую экрану 2, чем может быть обеспечена более эффективна защита веасывающей трубы от засор.ени ,The knives 3 are also curved in a spiral and can have a cutting edge on the inside, which is shaped in accordance with shield 2, which can be more effective in protecting the suction pipe from clogging.
работе устройства грунт режетс рабочими ножами 3, образукта с гидросмесь поступает во всасывающую трубу 1, всасываемый поток интенсифицируетс врашшошимис ножами 3 и 7. During operation of the device, the soil is cut by the working knives 3, the formation of the slurry enters the suction pipe 1, the suction flow is intensified by the large knives 3 and 7.
При наличии в грунте больших частей растений они попадают в зазор между внутренними кромками ножей 3 или 7 и кромкой всасывшошего отверсти .трубы 1 и разру баютс на части.If there are large parts of plants in the soil, they fall into the gap between the inner edges of knives 3 or 7 and the edge of the suction hole of the pipe 1 and are broken apart.
