Description

couples. One of the circular knives, adjacent to the pulley that is adjustable on the shaft, is mounted on the shaft 5 on the key, with the aim of installing it on the shaft depending on the length of the cuttings being cut. Shaft bearings 5 in brackets 5 installed

, movably in order to adjust the disc knives relative to the pulleys 2 by means of appropriate devices. The workers who sit in seats 47 and 48 pick up the prepared grapevine from the trays fortified in front of the seats and lay one by one in the grips of 4 ribbons 3. The latter, rotating in the direction of the arrows; (Fig. 1) carry the vine to the circular knives which, rotating in the opposite direction with respect to the pulleys 2, cut off both ends of the vines protruding from the grippers - #, and, the lower cut, due to the fact that one end of the vine lays in the grips 4 under the knot is cut along the diaphragm. The stalk cut from both sides is transported by ribbons to the furrow mechanism (Figs. 1, 3 and 4) installed in the middle part of the machine frame on the path of the lower branch of the transport belts passing between the guiding strips 10 with the ends 10a bent in reverse directions transversely movements of the belts 3. At some distance from the slats 10 and parallel to them, slats // are installed (Figs. 3 and 4), which, in combination with slats H, form guides for sliders 12, which are simultaneously bearings for the rollers 13. On the rollers 13 impaled qi Lindra 14, fixed in the desired position on the valts with the help of springs pressed into the corresponding depressions of the cylinders 14. To the latter, dies 18, made from the system of steel springs 18a (Fig. 4), are used to form grooves on the cuttings and remove excessive buds. The slides 12 are driven in a periodic reciprocating motion, slipping in the guides of 10- / Lot daoyin rods 22 (Fig. 2 and 3) connected to the axles of the rollers 13. The opposite ends of the rods 22 end with bearings 27, wearing fingers 2 of the levers 29 ( Fig. 1 and 2), mounted on the shaft 30. To the last

in its middle part, the paw 31 (Fig. 2 and 3) is rigidly riveted, receiving a swinging movement from the finger of the crank 32, by means of a connecting rod 33, which can move along the paw 31 and fasten on it in four positions corresponding to four lengths of grooves. The crank 32 is mounted on the shaft 34 (FIG. 2), the opposite end of which is provided with a bevel gear 55 rotated from the gear 36 of the shaft 37 carrying the pin gear 38 with twelve rollers -. The pinwheel receives a periodic movement from sector 39 with three teeth attached to a rotating shaft 45. At the same time, sector 59, turning with the owner 45, also knobs 40 of the conveyor shaft 5a also receive periodic rotation into periodic rotation. a worm gear pair 41, 42. A worm shaft 42 at one end carries a worm gear 43 coupled to a screw 44; receiving rotation from the tractor. The transmission is calculated in such a way that at 300 revolutions of the worm 44, sector 39 makes half a turn ..

The cutting of the cuttings takes place during the stopping of the conveyor belts. At the beginning of each stop of the conveyor, the slides 72 with cylinders 14, and, consequently, with combs 18, are in the initial initial position. When the conveyor stops, the cylinders (1NDry / 4, which, by teeth 19 (Fig. 3), abut against the ends of the stop dogs 20, begin to turn a certain part of the rotation, begin to make a forward movement, thereby driving the comb, the grooves are cut through them. The cylinders 14, moving further, meet the stops 77, which, abutting the recesses (Fig. 4), formed in the washers 16, mounted on the ends of the cylinders 14, rotate them to their original position, retraction from the cuttings of the comb 18. The transporter begins to move on. device, removes cuttings from tapes in the substituted baskets. This device consists of a roller 25 (FIG. 1), with radial grippers 46, driven in rotation by the shaft 1a by a chain transmission, b, c, d.
