Abstract

The invention relates to conveyor equipment. The purpose of the invention is to reduce spillage and laboriousness of installation of the device in the operating position. The device includes two side posts 5, rollers (P) 11 with axles 10. Around P 11 are closed sealing tapes (UL) 12 that interact with the load-carrying tape 3. There are 5 main horizontal levers mounted on the uprights 5, spring-loaded in vertical and pivotal in horizontal planes. On levers 7, additional levers 9 are mounted obliquely and rotationally in a vertical plane. Axis 10 R 11 spring-loaded relative to the levers 9 and are made conical at the bottom. On the inner surface of the UL 12 have protrusions located on R 11 by means of grooves formed in them. Racks 5 are installed movably with the help of carts 6. When the belt 3 is moving, UE 12 is turned, which interact with the belt 3 with their ends, ensuring compaction and formation of the traffic flow. The position of the belts is adjusted by the levers 7 and 9, as well as by the trolleys 6. Thus, the spills and the laboriousness of installing the device in the working position are reduced. 4 il.

The invention relates to conveyor equipment, namely, devices for compacting the loading point of a belt conveyor.

The aim of the invention is to reduce the spillage and labor intensity of the device in the working position. On league. Figure 1 shows schematically the proposed device for compacting the loading point of a belt conveyor, side view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows an arrangement of an additional lever with a roller} in FIG. 4 - cart layout.

A device for sealing the belt conveyor overload site is mounted, for example, in an aspiration sheath housing 1 with a suction air duct 2 located above the conveyor belt 3 and a drum 4 of the discharge head of the conveyor.

The device includes two side racks 5 movably mounted with the help of carriages 6. On the racks the main horizontal levers 7 are spring-loaded with springs 8 in vertical and rotatable in horizontal planes. On the main levers 7 mounted additional levers 9 obliquely and pivotally in a vertical plane. The levers 9 are spring-mounted on axles 10 rollers 11. Axes 10 are inclined and made tapered at the bottom for better interaction with the tape 3 and two sealing tapes 12. The tapes 12 on the inner surface have protrusions 13 located on the rollers 11 by means of in them along the generatrix 14. The belts 12 are closed around the rollers 11 and installed with the possibility of the lower ends interacting with the load-carrying belt of the conveyor. The lever 7 is mounted on a rack 5 equipped with a nut 15 and a fixing bolt 16 One end of the spring 8 is connected to the lever 7 and the other to the rack 5. The axes 10 of the t1 role are spring-loaded relative to the lever 9 by the springs 17 and have a nut 18.

The supports 5 are fixed on the guides 18 by means of the bolts 20.

The device works as follows.

When the movement of the conveyor belt 3 due to the presence of friction forces between the surface of the conveyor belt 3 and the ends of the internal branches of the belts 12, the belts 12 turn around the rollers 11. At the same time, the force of the belts 12 against the surface of the belt 3 and preventing the belts 12 from coming off the rollers during their rotation is achieved protrusions 13. When transporting the tape 3 of the crushed material of the tape 12 prevent the formation of spills. As the belts 12 approach each other, the formation of a bulk material is improved. The force of pressing the end of the belts 12 to the surface of the belt 3 is controlled by rotating the nut 18. Springs 17 mounted on the axis 10 provide the mobility of the roller 11 along the axis of rotation.

The presence of levers 7 and 9 allows you to change the angle of inclination of the roller 11 to the plane of the conveyor belt 3, as well as the force of pressing the axis 10 to the end of the belt 3 and the position of the belts 12 on the surface of the belt 3. The nut 15 fixes the position of the lever 7 on the rack during compression of the spring 8 , and the bolt 16, if necessary, secures the lever 7 on the rack.

For ease of movement of the belts 12 along the conveyor belt, the 3 racks are fixed on the carriages 6. The position of the carriage is fixed by the bolt 20. To seal the transported flow, the carriage moves towards the drum 4 until the rollers 11 are above or behind the vertical axis of the drum 4. In this case, the rollers 11 are reduced, if necessary, to the longitudinal axis of the conveyor belt 3. As the mass of the transported material increases, the rollers are diluted and reduced to the axis of the conveyor belt 3 as the mass of the material decreases, and the material itself condenses.

The compacted stream of material falls down from the surface of the conveyor belt 3. In this case, a reduction in the removal of dust from the volume of the falling stream of material is achieved.

Thus, the use of the proposed device allows reducing spills and the laboriousness of installing it in a working position.
