Implement for unloading bunker silos

摘要

Attached to the upper end region of the mounting (1) of the implement for unloading bunker silos is a guide frame (3), along which a cutting unit (5) is guided. The blade holder (19) of the cutting unit (5), which carries the cutter (4), is connected to the piston rod (18) of a working cylinder (17) designed as a double-acting cylinder. The cylinder chambers (23 and 24) of the working cylinder (17) are connected via hydraulic lines (15 and 16) to the cylinder chambers (21 and 22) of a pumping cylinder (14), the piston rod (13) of which can be driven by means of a crank drive (10). The crank drive (10) for its part can be coupled to the power take-off shaft (9) of a tractor (not shown). The crank drive (10) can, for example, be mounted directly on the power take-off shaft (9). All the cylinder chambers (21 to 24) are continuously full of oil, with the result that the working cylinder (17) and hence the blade holder (19) together with blade (4) are actuated by the forced forward and backward movement of the piston rod (13) of the pumping cylinder (14) brought about via the crank drive (10). <IMAGE>
