SU18990A1 - Adaptation to the harvesting machines for lifting the dead stems and placing them on the platform - Google Patents

Description

The invention relates to an overlapping fixture, for harvesting machines, preferably in conjunction with sheaves by rungs, in which up to the present time for shifting

the stalks j), the rods were used exclusively on a horizontal axis rotating the rods, grabbing the stems from the top parallel to the cutting cord and then laying them on the platform. Such a device, giving good results and working properly with vertically standing stems, does not always cope with the dead bread. ,

Instead of the above-mentioned reel,

apply a fixture in which

almost horizontally located

rods grip, rotate, stems

 ale, entrance to them from the side, after which they are laid on platforms. Due to the fact that the Kintsa of these rods describe an ellipse, more

the axis of which is parallel to the direction of movement, one gets a slow capture of the ears, prolonged folding and then quickly pulling out the rods of cut stalks. In the case of using the device with normal bread, it is equipped with a ring attached to

drive cross and intended to press the top of the stems inside.

The drawing shows an overlaying device with a sheave stub sheave, where FIG. 1 is a rear view of the device and FIG. 2 is a view from above.

The overlay device consists of four rotating rods with which are placed in front, on the right side, with the machine's over-cutting knife. These rods, on the one hand, are hinged on an approximately horizontally rotating frame, which is rotated, and, on the other side, are extended back far beyond the mentioned hinges, their ends, the slippers, are held in a stationary state; on the frame of the machine guide ring d. Owing to this, when the cross is rotated, the angle between the rods and the stems, the KOTOpbie must be compressed, all the time and changing. The crosspiece, revolving away from the axis of the traveling wheel, is provided with pins V at the ends of its four spokes for attaching the claws / holding the rods a. The cross receives rotation from the almost vertical shaft g located below it, which in the lower end is equipped with a universal joint and is rotated by means of

bevel gear i from the axis associated with the general mechanism of the machine. The crosspiece can be moved along the shaft along, for which the latter in its upper part has a quadrilateral section. Moving the cross over along the shaft, in order to bring the device into line with the height of the stems, is made by hand with a lever t, which rotates around a non-axial axis n, and the other shoulder of which forms a fork with shoulders lateral fingers of the ring q, located under the hub of the cross. This ring is not involved in the rotation, but only when moving the lever t. Raises the cross to the proper height. The lever is moving in a known manner along the groove segment r supplied with the groove; to balance the load of the lever, it is equipped with a spring S.

In order to establish each time the most suitable angle of inclination of the rods and to the ears, the guide ring d can be rearranged around the circumference of the arc t, concentric with respect to the shaft g of the cross. This also results in straightening and proper pressure on the standing stems of dangling ears.

The knitting needles of the cross of b are interconnected by a ring and protruding to the outer ends of the rods and rotating together with them, eliminating the ingress of the stems between the rods a and the cretin b, where they can become entangled and stop working.

 On the left, in front, to the net (Fig. 1), an external river separator of ears, which consists of two rods converging in front at an acute angle of v, which are parallel to each other in the rear part, is already attached in a known manner. The inner core of this separator is placed below the ends of the rotating rods a, so that the latter remove the spike from the separator during its rotation. /

The subject of the patent.

Claims (4)

1. An attachment to the harvesting machines for lifting the lodged stems and placing them on the platform, with rotating rods, characterized in that the rods a are articulated with the axle e of the cross, rotated from the axis of the running shaft, the wheels, and the idle ends of the rods are aligned with the possibility of sliding in the guide ring d. 2. The form of implementation of the device specified in Clause 1, characterized in that, in order to change the angle of the rods entering the bread mass, the guide ring d is made adjustable along the arc t, concentric with respect to the shaft of the cross. 3. The form of making the device according to claim 1 and 2, characterized in that for adjusting the height position of the rods, the cross b is mounted on the shaft g with the possibility of axial displacement with the help of the lever t, etc. 4. The form of execution of the device specified in p. 1-3, which is distinguished by using the envelope, the spokes of the cross of the ring, whose rim stands for the trunnion e, in order to prevent the cross from clogging with the stalks.
