Description

The invention is sucking machines for pulling flax using a reel, at the ends of the spokes of which are mounted movable blades for pressing the stems to the rotating drum under the action of springs. In the proposed machine, the blades are rotatable on the reel trunnions, and to interact with them, drums are installed that are installed with the possibility of vertical movement of their bearings. In order to straighten flax stalks, another reel was used, equipped with fingers, pivotally mounted on reel needles.

In FIG. 1 depicts the view; a lively view of the machine; FIG. 2 is a schematic side view of it; FIG. 3 is a side view of a device for straightening flax stems.

The carriage a (Fig. 1) is mounted on two pairs of wheels, of which the rear ones, somewhat larger in diameter, are equipped with spikes to increase the grip between the rim and the ground. On the right side of the cart, a moving flax-holding mechanism is fitted, which is rotated by means of chain 3 from a sprocket b, which is tightly attached to the rear axle pair of wheels. The circular motion of the same direction is transmitted to the reel b, to which the blade spokes r made of angle iron are attached by means of couplings. At the ends of these spokes, wooden blades e are put on, which can rotate on the axles o (Fig. 2) by a quarter of a turn and retain their constant position in the direction of the spokes by means of strip (trigger) steel springs attached to the spokes by bolts to. Below The reel is placed in three wooden drums l so that when the blades approach them, the blades turn, as shown in the drawing, and create between the rotating drums and the horse blade (jaws pressing force exceeding the resistance of the pulled flax. In order to increase the friction and elasticity necessary to keep the stem from deterioration, the blades and drums are covered with sheet rubber Kka with another rubber-replacing material (for example, tarpaulin on sawdust). The drums -t rotate in frame bearings .1 having vertical movement in the side of the squeezing spring W, which has an elastic resistance equal to the force of pressure of the blade on the drums. The drum l is located slightly below the drum l-2, with a whole more

reliable grasping of flax stems when bending them with reel blades. The rear drum l serves to transfer the plucked stems to the trellis, which directs the stems to the surface of the field. Gud with a grid of angular iron arranged cross-link f of the machine. A device for straightening flax stems (Fig. 3), consisting of a shaft, with a mounted reel of H1 several rows of straightening fingers, is installed in front of the pulling apparatus. Each finger is made compound and has the shape of a broken line; This form is maintained by a trigger or coil spring, which can resist in terms of: rotating forces, and in the case of significant resistance to flax (for example, with strong entanglement and interweaving of the stems, the finger overcomes the elastic resistance of the spring and, turning around the hinge p for some reason, releases from the resistance of flax in order to then emerge from the plexuses and take the initial position.

The movement of the rectifier apparatus is carried out through a chain drive along ijenHbiM wheels on shafts e and g of the same diameter.

For placing in the correct rows of harvested flax, a folding wooden lattice w (Fig. 1) is applied, which goes through flax and, as it accumulates, unloads across the field, lying flat, convenient for shearing transverse strips (as if resting). In this bluchae, the stems will not entice each other, and will also be confused, as they will, when rolling between the blade and the barabads.

Husking flax grains when it is pulled out will follow, since the upper seed part of the stem will not be subjected to pressure and rolling will capture mainly the lower half of the stem and its root.

The right side of the machine is supported by two wheels rolling on the ground. The frame of the trolley and flax-yielding apparatus are made of angular iron. The flooring of the cart is simple, wooden, with a seat: for one person and a crate for storing the necessary tools and spare parts.

The subject matter of the invention.

1. A machine for pulling out flax with a reel, at the ends of the spokes of which are mounted movable blades designed to press the stems to the rotating drum under the action of springs, characterized in that the blades are rotatable on the axles of the reel, and for interacting with them the drums l, installed with the possibility of vertical movement of their bearings m against the action of springs and from which drums L: and 2 the first one is located somewhat lower than the second, in order to more reliably seize the flax stems during the first his bending blades miovil (Fig. 1).

2. In the case of the use of a device for straightening flax stems, made in the form of a reel equipped with y-fingers, installed in front of the pulling machine, specified in clause 1. mounted on the needles of the reel pivotally on the hinges with the aim to ensure that they can be deflected against the action of the springs, if they fall into a mass of tangled. stems (Fig. 3).
