Abstract

The utility model discloses a no-button scoop lifter, belonging to the storage and transportation mechanism device of machines for grain and oil process. The protrusion part on the head of the lifter is formed by the tangency of an arc surface and two planes. The protrusion part is in gooseneck shape. The separation angle between the two planes which are tangential to the arc surface is less than 90 DEG. The separation angle between the upper plane and the horizontal plane of a bottomless bucket is greater than 0 DEG. The clearance is 0 to 5 mm. A squirrel-cage tail wheel is welded and provided with an inclined discharging wide plate. A trapezoidal discharging device is arranged in the machine base. The no-button scoop lifter solves the problems of multiple backflow grain, low efficiency, and high material breaking rate in the existing lifters. The utility model has the advantages of high full charge coefficient, high efficiency, energy saving, less backflow grain, and low material breaking rate.

Description

No-button scoop lifter

The utility model belongs to a kind of accumulating mechanical equipment in the grain and oil machinery.

At present, in the numerous grain depot of China, Grain and Cooking Oil Processing Factory or feed-processing plant, widely used is that end winnowing pan gig is arranged, and the grain depot of only a few and Grain and Cooking Oil Processing Factory, feed factory use bottomless bucket elevator.These two kinds of elevating gears can satisfy the operating needs that promotes material in the production substantially, are bringing into play certain effect.But, because the selection of above-mentioned old-fashioned gig structure and design parameters, it is improper to determine, as square or arc head, steel plate rolls or base, bottomless bucket basic specification and the clearance etc. of the squirrel-cage tail wheel of the as cast tail wheel or the discharge former that do not tilt, flat-bottom structure, make that existing two class gig ubiquities that the backflow flow vector is big, coefficient of fullness and operating efficiency be low, shortcomings such as power consumption and material percentage of damage height.

The purpose of this utility model designs a kind of later-model bottomless bucket elevator exactly, make its with in China produces, use at present all kinds ofly have the end or bottomless bucket elevator to compare, have the coefficient of fullness height, lifting capacity is big, backflow grain is few, percentage of damage is low, power consumption economizes, cleaning material advantage easily.

Basic design of the present utility model is, the head of this novel bottomless bucket elevator is forwards outstanding with respect to the mouth of putting out cereal, and its overhang is by arc surface and the plane is tangent constitutes, and is the gooseneck boom shape; Simultaneously, dwindle the clearance between bottomless bucket, the angle of inclination of plane and frontal plane is welded with inclination discharge former on the change bottomless bucket on the squirrel-cage tail wheel, sets up trapezoidal discharge device in the support.Thus, realize improving operating efficiency, save the purpose of the energy, reduction percentage of damage.

Below in conjunction with accompanying drawing the utility model embodiment is described in detail.Head (1), machine barrel (8), support (10), bottomless bucket band (7) and (6) five basic building blocks of bottomless bucket are formed novel bottomless bucket elevator.Bottomless bucket band (7) is surrounded between great wheel (2) and the squirrel-cage tail wheel (11).On bottomless bucket band (7), utilize bucket bolt fixing several bottomless buckets (6), the clearance L that its bottomless bucket (6) is gone up after fixing at bottomless bucket band (7) is 0～5 millimeter, by machine barrel (8) bottomless bucket band (7) and bottomless bucket (6) is sealed.The last plane of bottomless bucket (6) and the angle α of horizontal surface are greater than 0 °, and the angle β of frontal plane and vertical surface is 45 °.Head (1) is positioned at the top of whole gig, and forwards outstanding with respect to discharging opening (5), and preceding teat part is by arc surface and two planes are tangent constitutes, and is the gooseneck boom shape, and the angle γ between the tangent plane of two and arc surface is less than 90 °.In head (1) the inside great wheel (2) is installed.Squirrel-cage tail wheel (11) and trapezoidal discharge device (13) are installed in the support (10).On squirrel-cage tail wheel (11), be welded with inclination discharge former (14).Trapezoidal discharge device (13) is to be made by angle bar and iron plate processing welding.On support (10), also be provided with inlet point (9) and plate (12).Electrical motor (3), retarder (4) are installed on the platform on gig top.When promoting operation, electrical motor (3) is given great wheel (2) by retarder (4) with power transmission, and drive bottomless bucket band (7) and bottomless bucket (6) is surrounded on great wheel (2), squirrel-cage tail wheel (11) moves, at this moment, the material that is raised is fallen in the gig by inlet point (9), after bottomless bucket (6) takes, with bottomless bucket (6) upward movement, when walking around great wheel (2), material is dished out.The material of being dished out is because the restriction of the inwall of head (1) gooseneck boom shape, the preceding kinematic velocity of throwing reduces rapidly, and changes sense of motion, under positive action, material can only move to discharging opening (5) along the lower plane of head (1), and discharges through discharging opening (5).So just reduced material and dished out behind the bottomless bucket (6), the backflow index of flow amount that causes because of collision, rebound.Entering squirrel-cage tail wheel (11) in-to-in material in time discharges along inclination discharge former (14), drop in the support (10) and is promoted again, reduced the material percentage of damage that causes owing to the extruding between squirrel-cage tail wheel (11) and the bottomless bucket band (7) thus by bottomless bucket (6).When the material obstruction takes place in support (10), extract plate (12), the material of obstruction is discharged support (10) automatically along two waist inclined-planes of trapezoidal discharge device (13).
