Description

The invention relates to devices for the unloading and grinding of bags with compacted mineral fertilizers and can be applied in agriculture for the preparation of mineral fertilizers before applying them to the soil.

A device for unpacking and grinding bags with compacted materials is known, comprising a hopper, a chopper, a screening device made in the form of a vibrating screen, an inclined grate and a block of rotating rollers 1.

However, this device does not efficiently clean mineral fertilizers from scraps of sack tare due to their specific properties - sticking ability, hygrocurrency, etc., which leads to a decrease in productivity, loss of fertilizer m.

A device for unloading Meshchki with bulk material is known, which contains a hopper, a cutting mechanism located at its exit, a cutting mechanism mounted under it, a device for sifting the product, consisting of two rollers installed in two rows in a checkerboard pattern with elastic strips displaced by one relative to others

at 90 ° 2.

A disadvantage of this device is the low efficiency of cleaning fertilizers from bagging machines, since the balers on each roller are located in the same plane and move the heap from the mechkotary and fertilizers along the surface only in the longitudinal direction, it is not enough to grind it, which reduces productivity.

The aim of the invention is to improve the quality of cleaning material from the bag.

The goal is achieved in that the device for unpacking bags of raw material, contains a hopper, a cutting mechanism located at the exit of it, a device for sifting the product mounted below it, consisting of rotating rollers with elastic lines arranged in two rows in a checkerboard pattern. Bilami, offset one relative to the other by 90 °, bili on each of the rollers are arranged along helical lines with the right and left direction.

FIG. Figure 1 shows schematically a device for unloading bags with bulk materials, side view; in fig. 2 - screening device; in fig. 3 - the image with elastic bilami located along the helix, in axonometry.

The device for unpacking bulk containers with bulk material consists of frame 1 and a bunker 2 mounted on it, a grinding device 3, and removable beaters

0 4 and screening device. The screening device consists of rollers 5 with elastic strips 6 and a crate 7 located above them, made of bent rods, in the slit of which during rotation

, passes bily.

The device works as follows.

Bins with packed mineral fertilizers are loaded into the hopper 2 and fed into the grinding device 3.

0 The crushed material, together with the fragments of the sack container formed after grinding, are fed by the tines 4 to the grid 7 and the rollers 5 of the screening device. Under the action of bil b, the crushed material along with fragments of the trash cage is placed on the grate 7, mineral fertilizers are spilled on the shipping conveyor, and the scraps of the meccotra are moved out of the working area. However, due to the fact that bili 6 on each of the rollers

Q 5 are arranged along helical lines with the right and left direction of the crushed material with scraps of the bag and along the lattice 7 not only moves in the longitudinal direction (the direction of rotation of the rollers), but the rifle lines move

5 to the center of the grid. Since the billes 6 of the following rollers have exactly the same location, the crushed material with scraps of the sack tars in the process of moving along the grid 7 is intensively transferred from one helix to another, which promotes the shedding of the sap tars and fertilizers and separates the fertilizers adhering to the mestchrock. In addition, the impact of b on a bag-mater when they exit from the grid 7 does not occur simultaneously, but as each moves, which tells the heap an additional rotational movement as it moves along the grid 7.

All these factors contribute to more intensive screening of fertilizers through the grid, better cleaning

0 fertilizer from the bag and increase productivity during unloading.
