FIG. 2
NOVEL CLOSED TAIL DEVICE OF BELT CONVEYOR
TECHNICAL FIELD The present disclosure belongs to the technical field of belt conveyors, and particularly relates to a novel closed tail device of a belt conveyor.
BACKGROUND Belt conveyors are widely applied to the field of bulk cargo conveying of grains, coal, metallurgy and the like, and various powdery, granular and small-block materials are extremely prone to generating diffusion of small-particle dust in the conveying process. A tail device of a conveyor is close to a feeding section, so that materials are easily accumulated at the tail of the conveyor; then, the diffused small-particle material dust is extremely easily adhered to the surfaces of a roller and a bend pulley, so that a conveyor belt deviates, and the aging of the conveyor belt is accelerated; and in addition, small-particle dust invades into the roller and a bearing of the bend pulley, the service life of the bearing is shortened until the bearing is damaged, potential safety hazards are generated, and the problems seriously affect normal work of the closed belt conveyor.

DETAILED DESCRIPTION As shown in FIG. 1 and FIG. 2, dust particles generated by materials under a closed conveying condition are adhered to the surfaces of a novel dumbbell type transition roller 3 and a novel bend
pulley 7. A gap is reserved between left and right arc curved steel plates 3.2.3, 3.2.3' on the novel dumbbell type transition roller 3, and dust particles are driven to be discharged along the gap along with operation of the novel dumbbell type transition roller 3. A pulley body 7.4 in the novel bend pulley 7 is composed of twelve arc curved steel plates uniformly distributed in the peripheral direction, gaps are reserved among the arc curved steel plates, dust particles are driven to be discharged along the gaps along with operation of the novel bend pulley 7, and the dust particles flow through a material guide barrel body 7.5 to be distributed to the two sides and finally fall to the two sides of the bottom of a tail protective cover 9. When materials are accumulated on the two sides of the bottom of the tail protective cover 9, left and right bucket type feedback devices
7.2, 7.2' continuously throw the materials to left and right guide plates 5.4, 5.4', the materials
are guided to the middle of a conveyor belt 6 along the left and right guide plates 5.4, 5.4', the materials are automatically returned to the conveyor belt, and the tail materials are swept.
