Description

Folding arm bulk conveyer

The folding-jib bulk conveyor that the utility model relates to is the conveying machinery of loose unpacked material, more specifically says to be the grain conveying machinery that puts in storage.

When the large-scale warehousing of domestic each bulk cargo is at present put in storage, use at most when using the warehousing of direct shipment type band conveyor, particularly grain to carry, but original machinery can not adapt to the Hatch Opening design that large span and height do not wait more.As: to the large span storehouse, after putting in storage, grain is piled up in a side of nearly Hatch Opening, need carry out artificial secondary turn over smash, smooth, when so both taking a lot of work, labor strength is also big, and operating environment stirs up a cloud of dust, and influences healthy, moreover turn over and smash expensive 3 yuan approximately in grain per ton, increased unnecessary expenditures virtually.To the Hatch Opening superelevation, low excessively adjustment that can not be flexible adapts to, and can not adjust the drop point of grain (or other material) simultaneously, can only directly transport, and can not equal fortune, more can not mention flat fortune behind the desired height, so can not satisfy the use of privileged sites.Through detailed patent retrieval and Ministry of Commerce's scientific findings retrieval, domesticly do not find same design of the present utility model, in the Searches of Patent Literature, " the high dip angle belt conveyer of flexible arrangement " of No. 2088096 patent announcements of Chinese patent utility model though but flexible arrangement, to adapt to the Hatch Opening height and to stretch in the Hatch Opening, but be not folding-jib, load-transfer device is a scraper-type." the telescopic belt conveyer " of No. 2105477 bulletins, just flat fortune is flexible, does not all have same idea with the utility model.

The purpose of this utility model is to overcome the deficiency of above-mentioned direct shipment type band conveyor, provide a kind of can adapt to large span and differing heights Hatch Opening can adjust the material drop point, but and the folding-jib bulk conveyor of the flat fortune of folding arm.

The utility model is achieved in that sets up a movable folding arm (big frame and folding arm are the middle empty class cuboid frame that four angle bar or pipe are welded into) in big upper end of direct shipment type conveyer bevelled, below the big frame trolley wheel slideway is arranged, link to each other with front and back support respectively with the after poppet anchor shaft by trolley wheel, connect the ground wheel assembly again, as supporting.Big frame links to each other with the folding arm cardan axle with folding arm, is equipped with above the two and lifts roller, little carrying roller, guardrail, flap roller, and there are changed course roller, conveyer stretcher, elevating hopper, tail wheel down in the lower end of big frame.Changed course roller before the front end of folding arm has.The space is provided with the suspender belt roller in the frame of big frame, Ban Yaochu has deceleration actuating unit, middle changed course roller, worm gear (bar) assembly, load-transfer device is on each carrying roller, suspender belt roller, changed course roller, deceleration actuating unit, the side of big frame and folding arm is provided with the upper and lower pulley of accent arm, the changed course pulley of lifting pulley, dead sheave and the activity of adjustment folding arm front end of adjusting big frame lifting, each wheel is wound with corresponding lifting respectively or transfers the arm steel cable, is connected in respectively again on the deceleration actuating unit of worm gear (bar) assembly and band power-transfer clutch.

Advantage of the present utility model is: newly-increased folding arm can stretch into and adjust the material drop point in the Hatch Opening, make the material one-time-reach-place of putting in storage, adapt to large span warehousing pan feeding, avoided artificial secondary to turn over and smash, saved labour and spending, also exempted the workman and turn over the environment that stirs up a cloud of dust when smashing, influence healthy disadvantage, the folding arm angle, big frame height is adjustable in pairs, adapts to the Hatch Opening of differing heights and superelevation (low), can equal fortune simultaneously and promote after reach the flat again fortune of certain altitude, widened range of use, satisfied special requirement, load-transfer device is sideslip not, has prolonged fed distance and height, reasonable in design operating steadily, lifting freely, noise is low, operating troubles is few.
