RU2442310C1 - Rotary windrower with stacking of mowed stuff on belt - Google Patents

Abstract

FIELD: agricultural engineering.

SUBSTANCE: invention refers to agricultural engineering and can be used in machines for mowing and stacking of the grass roll on the belt. The windrower includes a belt roll fixed on the axis and consists of the frame with a reel, conveyor, and finger beam. The belt roll is situated opposite to the windrower discharge opening. Below the belt roll along its axis the pressure roller for forcing the belt against the stubble is situated. It is pivotally tied up to the roll axis with the drag bars. The loose end of the belt is fixed on the soil surface with a pintle. The sprocket is mounted on the belt roll axis. The end of the cantilever fitted plate made of an elastic material penetrates into the slots between the sprocket teeth. Due to the plate resistance, a spontaneous inertial belt unrolling is prevented in case of an abrupt change in the windrower running speed.

EFFECT: increase in the performance capability of the windrower operation.

Description

The invention relates to agriculture, in particular to haying equipment, and is intended for mowing and stacking the grass roll on a tape, performed simultaneously with the formation of the roll.

The closest in combination of essential features is a roll reaper with a film tape laying, consisting of a frame on which a reel, conveyor and finger bar are installed and containing a tape roll placed on the axis, located opposite the discharge window of the header, and below the tape roll and parallel to its axis a clamping roller is arranged pivotally connected to the axis of the leads, adapted to press the tape against the stubble (patent RU 2294081 C1, IPC A01D 34/125 (2006.01), A10D 57/20 (2006.01), 02.27.2007).

Technical disadvantage of this device: in the case of a sharp change in the header’s speed of movement, during braking or acceleration, a freely rotating ribbon roll under the influence of inertia is unwound in proportion to the header’s movement speed, as a result of which an excess of ribbon appears between the roll and the pressure roller, which does not exclude its probability crushing and shifting away from the unloading window of the header, which in turn leads to the dumping of the beveled mass on the stubble.

Technical task: to ensure the unwinding of the tape from the roll in proportion to the speed of the header and, as a result, its constant tension to prevent wrinkling or shifting away from the unloading window of the header.

Effect: increase the operational and technical performance of the header.

The specified technical result is achieved in that the roll header with laying the beveled mass on the tape consists of a frame on which the reel, conveyor and finger bar are installed, and contains a tape roll fixed to the axis, located opposite the discharge window of the header, and below the tape roll and parallel to it on the axis there is a pressure roller pivotally connected to the axis of the leads, adapted to press the tape against the stubble, and an asterisk is mounted on the axis of the tape roll, the end of which has a cantilever end a captive plate of elastic material.

The figure shows a schematic side view of a roller header with the laying of the beveled mass on a tape.

The roll header with laying the beveled mass on the tape (see Fig.) Contains a frame 1, an axis 2 with a roll of tape 3 mounted on it, mounted against the unloading window of the header and placed in front of reel 4, a pressure roller 5 located in front of finger bar 6 of the header on the level of the stubble and parallel to the axis 2 of the roll of tape 3. The pressure roller 5 by leads 7 is pivotally connected to the axis 2, mounted, in turn, on two arcuate brackets 8, enveloping the reel 4 and rigidly connected to the frame 1. The free end of the tape 9 is fixed with a pin 10 .On axis 2 of roll 3 rigidly behind an asterisk 11 is attached, into the hollows between the teeth of which the end of the cantilevered plate 12 of elastic material enters. Part of the finger beam 6 in the area of the discharge window of the header is covered with a protective casing 13.

The work of the roller header with laying the beveled mass on the tape is as follows.

To prepare the header for work, the following operations are performed. The roll of tape 3 is fixed on the axis 2. The free end of the tape 9 of roll 3 is brought under the pressure roller 5 and the unloading window of the header and is fixed to the soil surface with a pin 10. The part of the finger bar 6, which is opposite the unloading window, is closed with a protective casing 13.

When the header moves, the roll of tape 3 is unwound, rotating on axis 2. Tape 9, enveloping the pressure roll 5, is pulled by it and sent under the unloading window of the header. The slanted mass by the conveyor (not shown) of the header moves to the unloading window and is dumped onto the belt 9.

In the case of a sharp change in the header’s movement speed during braking or acceleration, the inertial forces arising in the roll are damped by the resistance of the plate 12 made of elastic material entering the depressions between the teeth of the sprocket 11. The working process takes place until the roll 3 is completely unwound, after which the next roll is installed.

At the end of the work or the transfer of the header to normal operation, the axis 2 and the pressure roller 5, as well as the protective casing 13 are removed.

Claims (1)

A roll header with laying the beveled mass on a tape, consisting of a frame on which a reel, conveyor and finger bar are installed, and containing a roll of tape fixed on the axis, located opposite the discharge window of the header, and pivotally connected to the axis below the roll of the tape and parallel to its axis with leashes, a pressure roller, made with the possibility of pressing the tape against the stub, characterized in that an asterisk is mounted on the axis of the tape roll, in the hollows between the teeth of which enters the end of the cantilevered plate of elastic mat iala.
