Description

one

The invention relates to the field of loading and unloading operations, in particular to machines for unloading bags with various loose materials.

A device for unloading bags of bulk material is known, comprising a housing, a bag feeding device located therein, consisting of rotating trays and needles for holding bags, and a cutting mechanism 1.

A disadvantage of the known device1 is the complexity of the design and incomplete emptying of the bags.

The aim of the invention is to more completely empty the bag.

This goal is achieved by the fact that the device for supplying the decoys is provided with thumbscrews, and the needles are hollow and communicated with a source of compressed air, while the pushers and needles are hingedly mounted on pivot trays. The cutting mechanism is a mechanism consisting of two curved gratings, between which a sawtooth knife is placed.

FIG. 1 shows the device in ms of the feed of pulp on the firing table, longitudinal section; in fig. 2 device at the time of bag feeding

knife, longitudinal section; in fig. 3 device at the time of pouring the product from the cut bag, longitudinal section; in fig. 4 is a top view, in FIG. 5 is a section A-L in FIG. one.

The device consists of a housing 1 on which a funnel 3 is installed on elastic shock absorbers 2 with a vibrating 6p 6 m mounted on its wall. Inside the jO panel there is a cutting unit MBITIkov consisting of two curved grids 5, between which a fixed saw-like blade 6 is fixed. Above the funnel is fixed Swivel trays 5, 7 rigidly connected with pushers 8, planted on two parallel axes 9 together with hollow needles 10, are fixed on racks 11. On the outer side of the body, there is a frame on the frame

0 drive 12 needles, pushers and swivel trays.

The device works as follows.

The bag, oriented in a horizontal position, is fed to the mouth of the trays. When the axis 9 is rotated, the needles 10 pierce the edges of the bag and, with their uprights 11, abut the pushers 8, turning them together with the trays 7.

0 Pushers feed the bag on. Fixed

sawtooth b, which pierces and rips its side surfaces. A full cut occurs as a result of the bursting of the bag, forcibly supplied by the pushers to the receptacles 5. At the time of the completion of the rotation of the unloading table, along with the bag halves divided into two parts, air is blown through the needle through the needle and the simultaneous vibrator is turned on. After the bag has been emptied, the needles, the pushers and the trays together with the bag halves returned to their original position. The next sacks arriving on the filling, the halves of the emptied miik collide with the firing table,

The use of the proposed device for unpacking bags with bulk material will ensure reliable emptying due to the possibility of repeated shaking of the halves of the opened bag, reliable control of emptying the bags when returning the table to its original position, simplifying the design by eliminating knife drives, dumping mechanisms and throwing out bags.

Claims (2)

1. A device for expanding the mesh material with a bulk material, comprising a housing, a bag supplying device, a rotating tray and needles for holding the bags, and a cutting mechanism that is different in that, With the Purpose of more complete emptying of the bags, the device for supplying the bags, the pushers are provided, and the needles are hollow and communicated with a source of compressed air; for example, the pushers and needles are hingedly mounted on the axles of the swivel trays. 2. The device according to claim 1, which is the fact that the cutting mechanism consists of two curved grids, between which a sawtooth knife is placed.
