Description

Patent No. 17190 describes a device for automatically cutting off a molded peat belt in which a system of levers and springs periodically drives an eccentric controlling the raising and lowering of a knife that cuts peat

, tape into pieces of a certain length., This invention provides

/ adaptation of knives to a variable speed of peat

, the ribbons and the prevention of weight loss when lowering the knife, for which purpose the lever connected to the shaft on which the knives are mounted, is connected to the eccentric by means of a spring, and the eccentric guide curve has a CYCLONE to the plane of rotation of its supporting disk. The specified device causes not only the alternate movement of the knives in the vertical plane, but also their simultaneous translational motion, which coincides with the displacement of the peat belt.

In FIG. 1 shows a general view of this device; FIG. 2 is a side view of FIG.

The longitudinal shaft 1 bears on itself a clutch 2 having the ability to engage with the insertion 3 by means of a system1 of levers and springs / described 9 patent & 17190 / with clutch

The latter carries on itself an eccentric curved guide surface with which the roller b fixed on the lever 8 can come in contact spring 19 (Fig. 2). The plane of the guide curve of the surface of the disk 5 is inclined with respect to its plane of rotation, in order to communicate to the shaft 9, to which the lever 8 is connected, periodic axial movements. The shaft 9, which rotates in the supports 10 above the system of rollers 14, on which the backing boards 13 with peat ribbon are pushed, is under the action of the spring 18, which pushes the shaft 9 in axial direction, and bears on itself knives 11 designed to cut the peat tape.

During the passage of the backing board carrying the peat tape on itself, along the rollers 14, the protrusion 12 on the board, via the pedal 15, connects the coupling 2 constantly rotating a1 with the insert 3, jointly rotating the axis of the disk 5. The curve directing the surface of the latter tells through the roller 6, the oscillatory movements of the lever 8, pressed by the spring 19, and the oscillations of the lever 8 and its displacement
