Description

The invention relates to a mechanical stalk feeder to a decorticator, in which the stalks are moved along the feeding table along their length through final ridges. Automatically protruding above the plane of the opatho-progressively moving slider as it moves toward the nursing rollers.

In drawing, 1 shows a longitudinal section of the machine; FIG. 2-general view of the machine; FIG. 3-top view of it; FIG. 4- detail of the device of the combers; FIG. 5 is a view of FIG. 4 in the plan.

The feeder consists of a metal or wooden frame /, a crank ala 2 carrying worker 4 and idle 3 pulleys and a chain sprocket 5, from which the chain transfers motion of the sprocket 6 sitting at the end of the axis of the nutrient roller 8. Rollers 7 and 8 are mounted one above the other, where the axles of the roller 7 are resting in bearings 9 that can move in the grooves W (figs 1, 2) of the frame. The springs 7 / which abut against the bearings 9 and the lining J2 constantly keep the roller J pressed against the roller 8 in order to achieve the supply of the stems without crushing them. The side walls of the frame / have grooves / J (Fig. 4) in which they move reciprocally - progressively

a slider 74, driven by a connecting rod 75 from cranked fat 2 (Fig. 1 and 3); In the slits of the slider J4 there are a number of slotted combs 76, which are integral with the levers 77, having the slits J8. 21 frame feeder. In the crest x} 6 there is a slit 24 (Fig. 4) in which the spring 25 is placed, resting with one end in the crest, and the other into the metal bar 26 attached to the lower surface of the slide 14. Spring 25 always tends to feed the crest together with the lever 77 up Sleeves 29 are screwed to the frame cross-member 57, in which pins 27 with L-shaped ends and a shaped washer 28 are placed. The lower ends of the pins 27 are under the action of springs 57. The sleeves are provided with stop lugs 30 fixing a certain angle of rotation of the pins 27. K cross-piece 57, parallels 32 (fig. 5) are also strengthened; they adjoin lateral edges during the movement of the slide 14 from the rollers with the processes of the long arms of the rotary 90 squares 55 installed at the leading edge

slider 14. Cone protrusions 5 - / (Fig. 5), mounted on the upper plane of the slider near the ridges, are used for preliminary fractional division of the stalk layer into bundles. The area of the table of the feeder, not overlapped by the slider 14, is covered with an iron sheet 36, under which the slider slides as it moves backwards. On the loading side, the feeder is provided with a removable grill 35 supporting the ends of the stems.

The feeder works as follows. On the table the feeder and the grille. 35 Put the unfolded. Preliminarily sheaf and put the machine into operation. When the slider 14 is in position, as indicated in FIG. 1, the tongue 16 is in the raised position, and the squares 33 are free and, with their upper L-shaped ends, stand parallel to the movement of the slide (Fig. 3). When the slider moves backward, the levers / 7, with their chamfered ends, enter under the L-shaped ends of the pins 27 and force them, along with the crests, to be pressed downward flush with the plane of the slider 14, giving a free code to the slider under a layer of stems. Upon further movement of the slide back, the squares 33 enter with their lower ends in parallels 32 and, therefore, rotate 90 °, with the upper L-shaped ends set across the ridges. At this time, the ends of the pins 27 drop into the notches 18 of the levers / 7, and the latter, together with the ridges, under the action of the springs 20 and 25, rise up, thereby pressing the bundles of stems to the L-shaped ends of the squares 33. When the slide 14 moves back to the right the tufts of stems clamped over the ridges are advanced to the rollers 7, S, captured by them and fed to the decorticator. The pins 27, which are at this time in the notches 18, when moving the shank 14 to the right, are pressed to the side until they come out of the notches 18 of the levers 17, after which they are. the action of the springs 57 is set to its original position. Thus, during reciprocating movement of the slide for each revolution of the drive pulley, a decorticator is fed

. a certain number of bunches to be processed stems.

The subject matter of the invention.

Claims (4)

1. Mechanical stalk feeder to decorticators, characterized by the use of reciprocating, below the plane-feed table with a slit, the moving slide 4 (Figures 1-4), fitted, at the front edge, with several notched combs 16, automatically protruding over the slide when moving to the nursing rollers 7-8, in order to move the stems along their length along the table while simultaneously pressing the stems turning 90 ° around their axes with the angles 33, also located at the leading edge of the slide. 2. The form of making the feeder according to claim 1, characterized in that the ridges 25 / upwardly pressed upwards by springs 25 (FIG. 4), which are one piece with the levers 17 rotatable on the 7P earrings and provided with notches 18, are passed through the slots near the edge of the slide. in it, in order to press the levers 77 to the slider serve spring-loaded, swiveling on the hinges 23, pawls 22, with the aim of lowering downwards the levers 17 are provided with bevelled ends, for pressing which downward bent ends of the springs of the springs 37 pressed down are used have ceasing occurs at the recesses 18, 77 of levers. 3. Form of execution of the feeder according to claims 1 and 2, characterized by the use of parallels 32 fixed to the cross-frame (Fig. 5), which adjoin the lateral edges with the processes of the long arms, turning 90 ° of the squares 33. 4.When the feeder according to claims 1 and 2 use reinforced several conical protrusions 34 (Fig. 5) at the leading edge of the slider, which serve for the preliminary fractional division into handfuls of a layer of stems. fmp fig 2 FIG 4    “-, a - / y HHTD .i4L2: i g si ha , F // “, zg: 3} .-L-, t-. .  : f t-I g - R-1Sh -f -f;
