Description

The portable device belongs to metallurgy and can be used for crushing single-use soft containers of the "Big-Bag" type with heavy-flowing lumpy materials, for example, with ferrosilicon, ferromanganese or with calcium carbide and other materials for loading into hoppers or container grabs.

A well-known device for crushing soft containers with loose material (USSR Patent Мо1209515, В658В 69/00, 1984), which contains a chamber with a loading window, which has a double-leaf door and a sealed double-leaf cover and an unloading hole, which are mounted with the possibility reciprocating movement of empty needles connected to the compressed air supply system and a cutting mechanism, while on both sides of the chamber there are upper and lower carriages with drives for their reciprocating movement along the guides, while the empty needles are placed on the upper carriages, and the saw-shaped knives are fixed on the lower carriages with the help of rods, in addition, two four-sided knives are installed on the rod of the additional carriage in the plane of the saw-shaped knife. On the side of the chamber there is a flange for the exhaust ventilation system, and in the upper part of the chamber, the flaps of the sealing cover are connected by flexible rods through the blocks to the upper trolleys, while the hole in the lower part of the chamber is covered with a grid designed to prevent the container from falling into the hopper.

The analogue of the device coincides with the proposed invention only in that the device for crushing soft containers of bulk materials contains four-sided and saw-shaped knives on rods.

The disadvantages of this device include the fact that the device cannot be installed on a hopper or on a grab container, in addition, the presence of five carts with pneumatic cylinders complicates the design of the device and increases its dimensions, which will not allow the device to be installed in narrow places between existing technological facilities.

It should be noted that this execution of four-sided and saw-shaped knives is permissible when crushing soft containers for heavy-flowing materials, for example, cement, since the knives, having pierced the fabric of a soft container, will easily move in the cement in a horizontal plane, than in the case of pieces of heavy-flowing materials .

A well-known device for crushing bags with loose material, such as cocoa beans (USSR Copyright Mo946998, B65B 69/00, 1979), containing a mechanism for feeding bags into

From the receiving hopper, the dropping tray is made straight with a support on the receiving hopper grid, and a dihedral knife of an isosceles triangular shape with inclined ribs in the form of stretches connecting the upper part of the knife with the receiving hopper grid and located in a plane is also fixed parallel to the bottom of the dropping tray , perpendicular to the knife plane.

The analogue of the device coincides with the proposed invention only in that the device for crushing bags with loose materials contains a triangular-shaped dihedral knife.

The disadvantages of this device include the fact that the device cannot be installed on a hopper or on a grab container, in addition, the presence of a grid will not allow pieces of heavy-flowing materials to pass through without vibration. It should be noted that the presence of only two blades of a triangular-shaped knife, if there are stretches in the form of ribs, will not allow cutting a soft container with pieces of loose materials, since these ribs, resting on pieces of loose materials, will inhibit the cutting of the container and emptying of the soft container

A well-known device for crushing bags with bulk material, adopted as a prototype (USSR Copyright Certificate Mo1279915, В65В 69/00, 1985), containing a hollow body with a receiving funnel, a discharge opening and a perforated wall, an air suction system connected to the body cavity through a perforated wall, and a nozzle having a hollow perforated pointed part in the form of a truncated cone with cutting knives and slots for the passage of material, the knives around the nozzle forming a four-sided knife, covering the conical part of the nozzle.

The closest analogue coincides with the proposed invention only in that the device for crushing bags with loose materials contains a four-sided knife installed on the body in the form of a nozzle.

The disadvantages of this device include the fact that the device cannot be installed on a hopper or a grab container. It should be noted that the presence of a cone-shaped nozzle between the tops of the knives in the upper part will prevent the bag from being cut, since the bag will not be cut in the area of the truncated cone and pieces of loose materials will rest against the surface of the truncated cone between the knives and the soft container will not be emptied.

The task of the invention is to carry out the crushing of soft disposable containers of the "Big-

Beg" with heavy-flowing lumpy materials.

The solution to the given problem is achieved by the fact that the device is portable for crushing single-use soft containers of the "Big-Bag" type with heavy-flowing lumpy material, for example, in bunkers or in grab containers, contains a funnel-shaped body with supports, in which holes are made for gripping devices cargo-grabbing mechanism, a four-sided knife, placed on the rods between the walls of the funnel-shaped body, and between the funnel-shaped body and the mentioned rods, holes are formed for the passage of pieces of material. The four-edged knife is mounted with the possibility of removal and consists of a two-edged flat knife and a one-edged flat knife, in which the tops are made of blades and below the blades there is a saw, and the blades of the two-edged flat knife intersect to form a point of intersection, and the one-edged flat knives are installed on either side of of the dihedral flat knife, facing each other, forming the point of intersection of the blades below the point of intersection of the blades of the dihedral flat knife, and fixed in the bearings made in the dihedral flat knife, which fix the one-sided flat knives above the walls of the rods, while the dihedral flat knife is located on two rods , and two one-sided flat knives are located on the other two rods and the rods are equipped with walls with fasteners for fixing the knives, and the fasteners of the two-sided flat knife and one-sided flat knives are made in the form of an axis with a shoulder and with a wedge-shaped hole for a wedge, while the shoulder of the axis is in contact with two-sided flat knife and one-sided flat knives, and the walls of the rods are in contact with the wedge. It should be noted that in the two-sided flat knife and in the one-sided flat knives, holes are made for gripping by devices of the load-grabbing mechanism when installing and removing these knives from the portable device.
