SUMMARY OF THE INVENTION: A self-unloading container comprises two half-bucket pivotally interconnected with lifting brackets, a horizontal cross-arm with a pulling frame fixed to the half-bucket hinges. The horizontal beam is made in the form of a support beam and a discharge beam placed with a gap relative to one another. The beams are mounted for movement along vertical rails rigidly connected to the lifting brackets. Hooks are mounted on the unloading beam. The axis of the hooks is located in one vertical plane passing through the axis of the pull frame and the lifting brackets. Along the unloading beam, an axis is installed with a two-arm lever rigidly fixed on it and eccentric cams mounted with the possibility of contact with hooks. A counterweight is mounted at one end of the two-shouldered lever, and a flexible bar is fixed at the other end. Pull chrome mounted on the unloading beam. 2 C.p. f-ls, 10 ill. ate with

the traverse 3 is made in the form of beams placed with one gap relative to the other, 7 and unloading 8 beams installed with the possibility of movement along vertical guides 9, rigidly connected with lifting brackets 2. At the same time, hooks 11 are installed on the unloading beam on the axis x 10, moreover, their axes are located in one vertical plane passing through the axis 12 of the stick frame 4 and lifting brackets. Along the unloading beam 7, an axis 13 is installed with a two-arm lever 14 rigidly fixed on it and eccentric cams 15 installed with the possibility of contact with the hooks 11. At the same time, a counterweight 16 is installed at one end of the two-arm lever 14, and at the other end the bending of the rod 17 is fixed. The pull rod 4 is fixed on the unloading beam 8, which in the initial position lies on the stops 18.

Loading and unloading using the proposed container is carried out as follows.

In the initial position, when filling the container with a load, its half-bucket is 1 s. The rods 6 provide a constant vertical position to the entire horizontal traverse 3. Thanks to this, the unloading beam 8 with the pulling frame 4, hooks 11 and the two-arm lever 14 and the eccentric cams 15 is oriented in the plane of the vertical rails 9 and lies on their stops 18. Moreover, between there is a clearance between the supporting 7 and the unloading 8 beams. The loosely suspended hooks 11 occupy a vertical position. Their yawns are located below the lifting brackets 2 with a gap. The two-armed lever 14 in the initial (horizontal) position is balanced by a counterweight 16, while the eccentric cams 15 do not act on the hooks 11. When lifting a loaded container, the hook of the lifting mechanism (not shown) is inserted into the pull rmo 4 of the unloading beam 8. When lifting the unloading beam 8, its hooks 11, picking up the gap, pick up the lifting brackets 2 of the container. At the same time, the unloading beam 8, moving along the vertical rails 9, rises from the stops 18 and lifts the whole onteyner. Then, by moving the container, for example, into the body of a motor vehicle, it is unloaded. To do this, it is necessary to install the container on a supporting surface, with further lowering of the hook of the lifting mechanism together with it under its own weight, sliding on the guides 9 lowers and rests on the stops 18 the unloading beam 8. The yawns of the hooks 11 fall below the lifting brackets 2 with the possibility getting out of contact with them. At this time, the sling located below, by tensioning the flexible link 17, acts on the two-arm lever 14, turning it at a certain angle. Since the two-arm lever 14 is rigidly mounted on the axis 13, on which the eccentric cams 15 are also rigidly mounted, it rotates the axis 13, and with it the cams 15, which abut against the hooks 11, turning them and deviating from the vertical position by an angle sufficient to bring their pharynx out of contact with the lifting brackets 2. At this time, the crane operator of the load-lifting mechanism lifts the hook, and with it through the chute rmo 4, the unloading beam 8. The latter selects a free gap; covers the support beam 7 and raises it. The beam 7 through the rods 6 raises the half-bucket 1, turning them relative to the central axis by an angle of up to 90 °. When lifting, the container opens and the contents are unloaded. At the beginning of the opening of the half-bucket 1, the sling removes the load from the two-shouldered lever 14. The axis 13, and with it the eccentric cams 15, are returned to their original position by balancing the two-shoulder lever 14 by the counterweight 16. The free-hanging hooks 11 again occupy a vertical position. The container freed from the load is lowered onto the supporting surface. With further lowering of the hook of the load-lifting mechanism, the unloading beam 8 slides downward along the vertical guides 9 under the action of its own weight and lowers to the stops 18. By pressing, the hooks 11 lower oblique sections, sliding along the lifting brackets 2, deviate from the vertical position. Passing an oblique cut, the hooks 11 break down from the lifting bracket 2: and, having adopted, the vertical position, the throat goes under the bracket 2. Having reached the stops 18 on the vertical guide 9, the lowering of the unloading beam 8 has stopped. At this time, the crane operator changes direction - moving the container up, the unloading beam 8 is lifted, and the hooks 11 pick up the lifting brackets 2, lifting the container. In this case, the half-bucket 1, under its own weight, unfolds and returns to its original position. The support beam 7 has taken its initial position, creating a gap between it and the unloading beam 8. Next, the container with closed half-buckets 1 is transported and installed in the loading zone by lowering the hook of the lifting mechanism. The unloading beam 8 lowered, lay on the stops 18 vertical

guides 9. The sling removes the hook of the load-lifting mechanism from the pulling frame. 4. The container is ready for loading and transportation.,

The design of the self-unloading container is easy to operate, safe to maintain, and increases labor productivity.
