Description

Aggregates are known for pressing large-stalked plants, in particular, for pressing reeds into bales, including a chassis and a chamber with sub-pressing and limiting levers.

In these aggregates, a clamshell loader is used to load reeds into the bale chamber and to ship finished bales.

In the proposed unit, in order to increase productivity, the shipment of finished bales is dried by an unloading mechanism, made in the form of pivoting arms, the free ends of which in the initial position cover the bottom of the bale chamber.

In order to improve the ejection conditions of the bale, the subpress levers and the limiting posts on the discharge side are made with pivot ends, which are connected to the levers of the unloading mechanism by means of tilting of the pivot ends of the limiting racks before the unloading mechanism operates, and form pitched guides when ejecting the bale.

FIG. 1 shows the proposed unit, side view; in fig. 2 and 3 - subpressing and unloading mechanisms; in fig. 4 is a view along arrow A in FIG. one.

On the undercarriage, for example, on a self-propelled chassis 1, a loader 2, a pressing chamber 3 with a subpressing mechanism and an unloading mechanism 4 are installed. The prepressing mechanism is mounted on frame 5 with two bodies 6, on which a pile is formed, subpressing front levers 7, prepressing rear levers 5 , cutters 9, front 10 and rear // limiting racks, hydraulic cylinders 12 and 13 of the pressing, hydraulic cylinders 14 cutters, locking / 5 sub-pressures, blocking the cutters of the control platform 16.

The unloading mechanism is mounted on frame 17 and is made in the form of pivoting arms 18, the free ends of which, in the initial position, enclose the bale chamber 5 from below. The pivoting levers 18 are moved by means of a hydraulic cylinder 19. At the top of the frame 17, a slope 20 is installed for derailing finished bales.

To improve the conditions of the ejection of the bale, the preloading rear levers 8 and the rear limiting posts // are made with pivotal ends. The rear arm 8 consists of a base 21 and apex 22 connected by a hinge 23.

A hydraulic cylinder 24 is mounted on the base 21, which serves to pivot the top 22 relative to the base in position 22a.

The cylinders 19 and 24 are engaged from one spool, but when turned on, the hydraulic cylinder 24 operates faster than the hydraulic cylinder 19, since the latter is throttled. Rear Restraints // Fold

in position Pa around the hinges 25 under the influence of the lever 26 mounted on the shaft 27 of the pivoting levers 18 and ti 28.

After the next bale is installed, the pressure levers are retracted to their original open position. The ejection hydraulics is activated. The first is folded to the cusp 22 and the tops of the 22 podpressovaniya levers. Behind them, the hydraulic cylinder 19 shuffles, the new levers 18 to the nano-step 18a. At the same time, when the arms of the t 28 are folded upright 11. When the levers 8 come to the top position, the kin falls out of them and rolls down to the ground.

Subject invention

1. A unit for pressing large plants, such as reeds, into bales,

including a chassis base, a chamber with a pre-press, im levers and limiting racks, loading and unloading mechanisms, characterized in that, with a new productivity, the unloading mechanism is made in the form of pivoting levers, the free ends of which in the initial position embrace the pressing chamber from the bottom. 2. An assembly according to claim 1, characterized in that

In order to improve the conditions of the ejection, the bales, subpress levers and limiting racks on the ejection side are made with pivot ends that are connected to the levers of the unloading mechanism by rods, ensuring that the pivot ends of the pivoting ends are tilted earlier by the unloading mechanism and form pitched guides when ejecting the bale.
