Abstract

FIELD: agricultural engineering; device for undercutting forest tree seedlings. SUBSTANCE: device has frame 1, band saw 11 whose ends are secured on sliders 9 installed on guides 10 rigidly coupled with frame 1 and mechanism providing reciprocating of band saw 11 over arc of circumference. Geometrically equal eccentrics 4 are installed skew-symmetrically on ends of driving shaft 3 of reciprocating motion mechanism of band saw 11. Eccentrics 4 are spline-connected with geometrically equal eccentric bushings 6 also installed skew-symmetrically Rolling bearings 7 are secured on eccentric bushings 6. Outer races of bearings are arranged in ports of frames 8 rigidly coupled with corresponding sliders 9. EFFECT: improved operation of device. 1 dwg

Изобретение относится к сельскохозяйственному машиностроению, в частности к устройствам для подрезания корней сеянцев лесных культур. Цель изобретения - повышение эксплуатационных качеств устройства. Устройство для подрезания корней содержит раму, ленточную пилу, концы которой закреплены на ползунах, установленных на жестко связанных с рамой направляющих, механизм возвратно-поступательного движения ленточной пилы по дуге окружности. Новым в устройстве является то, что на концах ведущего вала механизма возвратно-поступательного движения ленточной пилы кососимметрично установлены геометрически равные эксцентрики, шлицевыми соединениями связанные с геометрически равными и кососимметрично установленными эксцентриковыми втулками, на которых закреплены подшипники качения, наружные обоймы которых расположены в окнах рамок, жестко связанными с соответствующими ползунами.The invention relates to agricultural machinery, in particular to a device for cutting the roots of seedlings of forest crops. The purpose of the invention is improving the performance of the device. The device for cutting roots contains a frame, a band saw, the ends of which are fixed on sliders mounted on rails rigidly connected with the frame, a mechanism for reciprocating the band saw along an arc of a circle. New in the device is that at the ends of the drive shaft of the band saw reciprocating mechanism, geometrically equal eccentrics are mounted obliquely, splined with geometrically equal and obliquely mounted eccentric bushings, on which rolling bearings are mounted, the outer cages of which are located in the frame windows, tightly connected to the corresponding sliders.
