Abstract

This invention relates to the mechanization of loading and unloading operations and can be used in the chemical, food, construction and mining industries. The purpose of the invention is to increase productivity and prevent loss of bulk material. The meshes fall between one rotating drum of reel 2 with grooved protrusions 8 and knives 3. Tara is cut and the material is poured through a sieve into a receiving bin. The pieces of the slip material are destroyed by the protrusions 8. The inclination of the knives moves the material and the pieces of the container to the middle to enhance the destructive effects. 2 Il.

FIG. 2

This invention relates to the mechanization of loading and unloading operations and can be used in the chemical, food, construction and mining industries.

The purpose of the invention is to increase productivity and prevent loss of bulk material.

The use of the invention in the national economy in unpacking bags of bulk material allows for improved emptying of the bags and reduced losses.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

The bag unloading device comprises a tilting device 1 of a stack of bags, mounted below it rotatably about a horizontal axis, drums 2 with knives 3, a sieve 4, a receiving hopper 5 and discharge conveyors 6 and 7 for the material and bags. It is provided with corrugated linings 8, a funnel 9. The bags are fed to the drums 2, which rotate in opposite directions. At the same time, they are ripped by knives 3 and moved by their side surface set at an acute angle ct,

 to the middle. At the same time, the pads 8 with a corrugated convex surface effectively crush lumps of material. Bulk material and container pieces are pushed through the gap between the drums 2 and fall onto a cylindrical sieve 4, where the bulk material separates from the container pieces and enters the hopper 5 and further onto the conveyor 6. The container pieces are conveyed by the conveyor 7.

Invention Formula A device for unloading bags with bulk material, containing a tilting device of a stack of bags, mounted on the surface of the drums 20 under it rotatably between knives 3, and the latter are mounted with an acute angle about the horizontal axis of the drums ( sieve, receiving hopper and outgoing bones of radial section of drums 2. In the conveyor for the material and bag, the upper part of the device is mounted in such a way that, in order to increase the funnel 9. From the average radial 25 output and to prevent the cutting of the drums 2, the knives 3 are directed to rub in the bulk material. The device operates as follows: the drums between the knives, and the last ones are installed at an acute angle to the top. The stack of bags is placed on the radial plane of the cannula section Product 1 and then overturn in the reception of 30 drums. funnel 9. Bags are fed to drums 2, which rotate in opposite directions. At the same time, they are ripped by knives 3 and moved by their side surface set at an acute angle ct, to the middle. At the same time, the pads 8 with a corrugated convex surface effectively crush lumps of material. Bulk material and container pieces are pushed through the gap between the drums 2 and fall onto a cylindrical screen 4, where the bulk material separates from the container pieces and enters the hopper 5 and further onto the conveyor 6. The container pieces are removed by the conveyor 7. /five Invention Formula
