Изобретение относитс к области промышленного транспорта, а именно к устройствам ДЛЯ разгрузки ленточных конвейеров .The invention relates to the field of industrial transport, namely, devices for unloading belt conveyors.

Известно устройство дл разгрузки ленточных конвейеров, которое содержит сбрасывающий плужок и выполаживлющий ленту СТОЛ 1. Такое устройство малоэффективно в работе, так как требует приводного механизма значительной мощности дл подъема выполаживающего ленту стола.A device for unloading belt conveyors is known which contains a drop plow and a tape-drying TABLE 1. Such a device is ineffective in operation, as it requires a drive mechanism of considerable power for lifting the table-cutting tape.

Известно также устройство дл промежуточной разгрузки ленточного конвейера, которое содержит плужок и выполаживающие ленту ролики, св занные посредством рычажной системы с приводным механизмом подъема плужка и установленные на опорной раме 2.It is also known a device for intermediate unloading of a belt conveyor, which contains a plow and tape-drying rollers connected by means of a lever system with a drive mechanism for raising the plow and mounted on a supporting frame 2.

Целью изобретени вл етс уменьщение т гового усили приводного механизма за счет уравновешивани усилий, действующих на ролики и на плужок.The aim of the invention is to reduce the pulling force of the drive mechanism by balancing the forces acting on the rollers and on the plow.

Дл этого устройство снабжено расположенными ВДОЛЬ конвейера полыми валами с жестко закрепленными на них выполаживающими ленту роликами и смонтированными в подшипниковых опорах на опорных рамах , при этом внутри полые валы имеют торсионы с КОНСОЛЯМИ квадратного сечени , одна из которых размещена в квадратном отверстии вала, г друга консоль снабжена ДЛЯ обеспечени предварительного закручивани торсиона двуплечим рычагом с выступом на каждом плече, расположенным в прорези подшипниковой опоры.To do this, the device is equipped with hollow shafts arranged along the conveyor with rollers flattening the rollers and mounted in bearing supports on the support frames, while inside the hollow shafts have torsions with square CONSOLES, one of which is housed in a square shaft hole, another console Equipped to provide a pre-tightening of the torsion with a double-arm lever with a protrusion on each shoulder located in the slot of the bearing support.

Claims

The device for intermediate unloading of belt conveyors with grooved roller supports comprises frame 1. on which a lifting and lowering plow 2 and tapered rollers 3 are mounted, connected by a system of levers 4 to a plow lifting drive 5. In order to reduce the pulling force of the plow, the device is equipped with hollow shafts 6 installed in bearings 7 and 8 along the conveyor and made with square internal holes at one end, with a torsion bar 9 with consoles 10 mounted throughout each hollow shaft and 11 square sections, one of which 10 is placed in the square hole of the hollow shaft, and the other 11 is equipped at the end for pre-twisting the torsion 9 with a double-arm lever 12, each arm of which has fixing protrusions 13, and on the supports 7 of the hollow shafts there are arcuate slots 14 interconnected with the protrusions of the levers. The force from the plow lift drive is transmitted to the swivel rollers through the lever system 4 by means of the rod 15. When the torsion bar is twisted, a square bracket 10 fixed in the square hole of the hollow shaft 6 is resting in the sub-holder 8, and the double-arm lever 12 having a square hole fixed the square cantilever 11 rotates to the required angle and is fixed with the help of the locking protrusions 13 of the two shoulders lever 12 and the arcuate slots 14 made on the flange of the support 7. The twisted torsion 9 tends to turn the floors shaft with castors. The plow, when it is lowered to the belt through a system of levers 4, returns the rollers to the horizontal position by means of the cable 15 and twists the torsion bar. When the plow is lowered, the material from the conveyor belt is unloaded. Swivel rollers occupy a horizontal position. The torsion is twisted at the same time and has potential energy. The plow and the swivel rollers are interconnected by a lever system so that the force from the torsion is balanced by the moment created by the mass of the plow. In the process of lifting the plow, the drive moment is generated by the mass of the plow, the torsion, giving away potential energy, helps to lift the plow when. In this case, the swivel rollers, turning, give the rotary belt a grooved shape, passing the material to the next unloading point. The forces from the plow and torsion are balanced so that the force from the drive needed to lift the plow can be close to zero. Apparatus of the Invention A device for intermediate unloading of a belt conveyor, comprising a plow and tape-drying rollers connected by a lever system with a plow lifting mechanism and mounted on a support frame, characterized in that, in order to reduce the driving force of the drive mechanism, it is provided with conveyor hollow shafts with tape rollers which are rigidly fixed on them and mounted in bearing supports on supporting frames, while inside the hollow shafts have The ribs with square consoles, one of which is located in the square hole of the shaft, and the other console is equipped to ensure that the torsion is pre-twisted with a double-arm lever with a protrusion on each shoulder, located in the slot of the sub-support.
