SUMMARY OF THE INVENTION: The baler comprises a frame, a pick-up, a compacting device, a pre-chamber and a bale chamber, a device for securing the rolls. The coil fixing device is equipped with active piercing elements and an eccentric drive, and in the sealing device the upper drum is offset from the center of the lower drum and has spring-loaded fingers. 3 hp ff, 5 ill.

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery specifically to round balers for hay materials.

The purpose of the invention is to ensure the reliability and continuity of the extrusion process, increase productivity and provide a non-clamping roll.

FIG. 1 shows a general view of the baler (diagram); in fig. 2 - roller of the sealing device; in fig. 3 - lead drum; in fig. 4 — tensioning device of the pressing element; in fig. 5 - device of baseless fastening (firmware) of rolls.

The round baler (Fig. Contains a frame 1 on which the pick-up 2 is mounted, compacting rollers 3 are immediately behind the pick-up; the upper roll is shifted forward relative to the lower one; the preliminary chamber 4 consisting of three working elements - 5, 6 , 7 conveyor type, press chamber 8, continuous belt

the pressing element 9, the tension device 10, the roll density sensor 11 in the form of a spring-loaded swinging two-arm lever with rollers, a lever-eccentric device (mechanism) 12 for opening the press chamber, levers 13, active piercing rollers 14. 15 and a driving drum. The press chamber 8 consists of two semi-cylinders 16 with rollers 17, and the sealing rollers 3 have spring-loaded fingers 18 and grooves 19, the driving drums 15 are made in the form of a torus with grooves in which rubber bands 20 are laid

The device works as follows.

The material to be pressed is picked up from the surface by the floor by the pick-up 2 and is fed to the compacting rollers 3, where material is pre-compressed to reduce the elastic properties of the stems, then the material passes the preliminary chamber 4, enters the press chamber 8, where a coil is formed with continuous belts 9 . When the roll reaches the required density,

The pressure sensor 11 and then the mechanism 12 for opening the lower part of the bale chamber is triggered and the roll under the influence of the belts 9, which will return to the initial position by the tension device 10, will come out to the levers 13. active rollers and stitched (fixed) from unwinding. Later the cycle repeats: a new roll from the bale chamber enters the tray, and the fixed roll enters the vehicle.

In order to ensure the continuity of the process of pressing the feed without stopping the press assist, after the removal of the HRD from the press chamber, a preliminary chamber 4 is provided, which serves to cut off the feed flow and initial formation of the roll core. This is done in the following way: when the roll is formed in the press chamber, the feed passes freely through the preliminary chamber, during this period the working elements (belts) of the conveyors 5, 6, 7 move in the direction of feed movement. At the moment when the pressure sensor 11 is triggered, the press chamber starts to open with mechanism 12. But reversing of the conveyors 5, 6 also occurs, and also the conveyor 5 lowers, hiding the window into the press chamber. Thus, the feed is cut off, and then everything repeats.

Claims (4)

Claims 1.
