Description

The invention relates to cotton harvesting machines with spindles installed in different planes within the normal height of the bushes on endless belts or chains and rotating when passing through cotton bushes to pick cotton in one direction and after leaving them to another to release the harvested cotton on them. In the proposed machine, in order to facilitate the fall from the spindles of the heated cotton, while rotating them outside cotton bushes and in order to protect the leaves from injury, the spindles are equipped with a cord tape with hooks, the ends of which are bent at an acute angle.

In FIG. 1 shows a perspective view of a cotton picker; FIG. 2 is a top view of it; FIG. 3 is a top view of one section of the machine; FIG. 4-side section view; -fig 5 is a longitudinal section of the spindle; FIG. b-type spindle from the butt.

The cotton harvesting machine consists of several sections, each of which is formed from pairs of vertical 7 ps 7 with horizontally mounted 2 teeth on top and bottom of them, carrying endless belts or chains 3. The chains are interconnected by vertical bars Za-Za on which horizontally or inclined, mutually in the chess order, the spindles are installed

4, equipped with a cord tape 5 with hooks 5a, the ends of which are bent at an acute angle. Near the chains, along the edges of the latter, are guides

6, on which these spindles rest, retain their horizontal or inclined position. Near the protruding links on the other side of the chain of spindle ends, made in the form of rollers 4a with a friction surface, there are guides 7, to which the said rollers 4a of spindles 4 are adjacent. Guides 7 on one side of the section are located under rollers 4a, and on the other, above rollers. This is intended so that, when the chain moves, the spindle, which are driven by the rotational friction clutch of the rollers 4a with these guides

7, vrash on one side, in one direction, and on the other in another. The pairs of axles / - / with the parts described above are mounted on a frame with a wheel travel and so that the distances between the rows of spindles rotating in the direction of the crook of their hooks correspond to the normal distance between the rows of cotton bushes. The number of pairs of axles 7 with 2-2 gears, chain of flax 3 and spindles 4 can be different. FIG. 2 shows schematically, in plan, for example, a machine with four pairs of such axes.

When picking cotton, the machine is installed on the heads of cotton plants so that the spindles rotating in the direction of bending their hooks fall in the plane of these plants and between the branches, i.e. entered the bushes when driving this car along the ladies; axis 7 with the above details, by means of gears known in the art (for example, shafts with bevel gears, gall chains, etc.), is rotated.

P dviereten; rotating their hooks in the direction of bending, the passage through the bushes of cotton, touch its heads (boxes) and, grabbing ripe cotton with hooks from open boxes, wind it up on itself. The removal of cotton from the spindles occurs when the chain moves with the spindles outside the bushes, that is, over the space between the rows of cotton plants. Here, the spindle, due to the position of the guide 7 (Fig. 1) above their friction rollers 4a, is rotated in the direction opposite to the bend of their hooks, so that the cotton is easily removed from them, for example, with fixed brushes 8 (Fig. 2), installed in places where the spindles change their direction of rotation. The cotton removed from the spindles falls down, for example, on a platform located under the machine bed, and conveyor belts can be installed on this platform to deliver the harvested cotton to a special

storage following the car. Hooks 5a, bent at an acute angle, make it easier for cotton to fall off during rotation of the spindles outside the cotton bushes and, in addition, protect the leaves and branches of the cotton as the spindles pass between the bushes.

In order to increase the plane of capture of cotton and the favorable angle of the spindles in relation to the bushes, a pair of axles 7 with the above details can be tilted to the desired angle by tilting the bed on which they are mounted, for example, by means of a lever I associated with the bed suspended on the 7L axis. The angle of inclination of the frame is fixed by the arc 77 with the gear, with which the prong of the lever I

The subject invention.

A cotton harvesting machine with spindles mounted on endless belts or chains and rotating when going through cotton bushes to one side and after leaving them to another, characterized in that the spindles are provided with a cord tape with hooks whose ends are bent at an acute angle , in order to facilitate the falling off of the hooked cotton when the spindles are rotated outside the cotton bushes in the opposite direction and in order to protect the cotton leaves from being wounded by hooks.
