SU143688A1 - Unloader for handling material from stack - Google Patents

Description

Unloaders for transferring materials from the stack are known, including cantilever supports, which can be mounted on both sides of the frame of the undercarriage, rotatable in a vertical planar, and dump conveyors. However, these unloaders are not applicable for unloading the wool.

In order to eliminate this drawback, the conveyors of the proposed unloader are equipped with tools with a collar set and knocking drums installed at the coptice drums of the conveyors.

FIG. 1 shows the described unloader in general; in fig. 2 - its kinematic scheme.

The unloader is mounted on the frame of the undercarriage 1, moving with the help of a two-drum trailer winch along a narrow gauge track along the mills, from which the wool is discharged. The unloader consists of a feed conveyor 2 and a dump conveyor 3, which are mounted on a trolley / console. The feed conveyor is made in the vertical plane relative to the hinge 4. The conveyor belts have a pin headset 5 for taking the wool and the possibility of transporting it at large angles of inclination of the conveyors. To remove the wool from the headset, knocking drums 6 and 7 are provided, located at the end drums of the conveyors 2 and 3. The knocking drums are made in the form of cylinders, which form corners around the cylinders. Both conveyors are enclosed in a common casing 8. The conveyors are driven from electric motor 9 via gearbox 10. Power from the output shaft of the gearbox is transmitted to the main shaft 11, onto which an asterisk 12 is rigidly mounted. From this sprocket, rotation is transmitted through a series of chain gears the conveyor drum 3. From the second drum of the conveyor 3 through the chain transmission is transmitted rotation to the shaft 14 1436882

water drum conveyor 2. On the main shaft 11 is also firmly planted sprocket 15 and gear six. 16, from which through a chain drive, and. gears are transmitted to the two-way clutch clutch 17. Drum 18, cables of which are connected to the ends of the upper drum of the rotary transnorter 2, are loaded onto the shaft of the coupling 17. Lowering and raising of the conveyor 2 is carried out when the cam coupling 17 is turned on (right or left). Pulley 19 is mounted on the other output shaft of the gearbox 40, through which the belt drive system is transmitted to the shafts of the knocking drums b and 7.

Discharger works as follows. Approaching a labaze with a double-track track with a double-drum reversible winch, the unloader is connected to the electrical network, after which the conveyors begin to work. When the coupling 17 is turned on, the conveyor 2 descends slowly into the storage shed and, with its headset, picks up the fur, which, approaching the churning drum 6, lowering together with the conveyor 2, knocks onto the conveyor 3. transporting it to its destination.

The lifting of the conveyor 2 from the warehouse after the unloading of wool takes place when the clutch 17 is switched and is much faster than lowering, since in this case the shaft of the drums 18 is connected to the main shaft // only through a chain drive.

The Stavropol Economic Council informs that according to this proposal the design bureau of the light and furniture industry is developing drawings for the production of a prototype.

Subject invention

An unloader for unloading materials from the stack, which includes a cantilever reinforced on both sides of the frame of the undercarriage, rotatable in a vertical plane, and a dump conveyor, characterized in that, in order to use it for unloading wool, the conveyors are equipped with a tape with a calf headset and knocking drums, installed at the end drum conveyors.
