(54) DEVICE FOR CONTAINER EXPANSION

I

The invention relates to container shipping and cargo handling, and is mainly intended for mechanization of unloading of soft disposable containers.

Soft containers are made from polyethylene and polypropylene-based polymer yarns; they are used for transporting and storing bulk materials, such as sulphates, soda, charcoal, silica sand, cement, mineral fertilizers, and non-ferrous metal concentrates.

A device for unloading containers is known, which contains a bunker, supporting bars fixed above it and knife plates 1 arranged in them.

However, the known device does not provide loosening of the material, which leads to congestion during unloading.

The aim of the invention is to increase the reliability of operation.

The goal is achieved by the fact that in the container unloading device containing a bunker, supporting bars fixed above it and the new plates located in them ;; s, the ends of the latter located in the supporting bars x, are adjustable to the distance between them; their free ends are interconnected.

In this case, the supporting bars are removable.

FIG. 1 shows a device for unpacking containers, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 is a diagram of the operation of the device.

The device includes a hopper 1, on which four lugs 2 are firmly fixed, in the grooves of which the support bars 3 and 4 are freely installed. The bars 3 and 4 are fixed 15 in the lugs 2 with screws 5 and have slots 6 in which the knife plates 7 and 8 with their tail portions 9. The tail portions 9 of the blade plates 7 and 8 have rounded edges 10 resting on the bars and are fixed in slot 6

20 by means of bolts 11, passed through holes 12 and 13. Holes 12 serve to change the angle of inclination of the knife plates, holes 13 to change their position in height. In the upper part of the plate pivotally connected, for example, using rivets 14 and 15. Knife plates 7 and 8 have notches made in the form of notches 16, which improve the loosening of the load in the container 17. The device works as follows. The container 17 is placed on the blade plates 7 and 8, at which time the shell of the container is cut and the plates loosen the lower layers of the load. The container is lifted by 100-150 mm, and the load under its own weight moves from the container to the hopper 1. When lifting the container, the notches 16 have an additional loosening effect on the cargo. For each load and the size of the bottom of the container, a certain angle of inclination ol is selected. and the height of the knives. Considering that the angle of repose; 5 for known bulk materials is 15-45 °, and the sizes of the bottom of the containers are from 900 X 900 to 1200 X 1200 mm, it is recommended to adjust the angle of inclination of the knives from 20 to 50 °, i.e. the angle of inclination of the knives compared to the angle of repose by 5 °. Such an increase ensures an optimal intersection of the slip planes and a sufficient volume of loosening of the load. To adjust the position of the knife plates, it is necessary to remove the bolts And, dilute or move the knife plates 7 and 8, having combined the holes in the tail parts of the knife plates with the holes in the bars 3 and 4, put and fix the bolts. The chamfering of the edge 10 is carried out in such a radius so as to ensure its contact with the bars when adjusting the blade plates. This ensures that the load on the knife plates is perceived not only by bolts AND, but also by the longitudinal section of the knife plates. increasing design reliability. The rounding of the groove is selected in such a way as to ensure that it contacts the blade plate 7, i.e. the rigidity of the structure. When adjusting the blade plates for the height of the edge 10, they no longer come into contact with bars 3 and 4. The device can be installed not only with a bunker, but also above the discharge funnel. Placing the support bars with a support in the middle of the walls of the bunker, and not in the corners, allows the use of shorter bars with a smaller cross section. Using screws with screws allows you to remove the device from the hopper if necessary. Knife plates can also be easily removed for replacement. The proposed device allows you to speed up the emptying of containers by 10-15%, which can reduce the cost of transporting goods by 0.4-0.5 rubles / ton. Claim 1. A device for unloading containers, containing a bunker, supporting bars fixed above it and knife plates arranged in them, characterized in that, in order to increase reliability of operation, the ends of the knife plates located in the support bars are mounted with the possibility of adjusting the distance between them, and their free ends are connected to each other pivotally. 2. A device according to claim 1, characterized in that the supporting bars are removable. Sources of information taken into account in the examination 1.
