Abstract

The utility model relates to a spiral stirring feeder. A half shaft 9 which is fixed to an output shaft of a speed reducer is connected with a stirring feeding shaft 11 through a flange, the outer part of the half shaft is provided with a seat cavity 10 and the outer part of the seat cavity is provided with a rubber sleeve 8. A flange 6 which is arranged on the outer part of the half shaft 9 is fixed with a connecting flange 2 on the speed reducer 1 through a short shaft 3 which is arranged in a shaft sleeve 5 on the connecting flange 2, and a rubber sleeve 4 is arranged between the short shaft 3 and the shaft sleeve 5. A connecting plate 14 which is connected to one end of the seat cavity 10 by bolts is also connected with a bolt 15 on the flange 6, and a rubber sleeve 13 is arranged in a matching hole of the bolt 15 and the connecting plate 14. The single end flexible supporting structure is used for the stirring mixing feeding shaft of the utility model, a discharge opening of a charging barrel is not provided with supporting obstructs and the feeding resistance force is reduced. When the radial abrasion of a vane of the stirring feeding shaft occurs, the single end flexible supporting structure can automatically generate compensation to make the stirring feeding shaft assembly not generate the deflection deformation and cause the abnormal abrasion of a sealing member on the shaft.

Description

The helical stir pay-off

Technical field

The utility model relates to a kind of helical stir pay-off that concrete is carried that is used for.

Technical background

Be used for concrete helical stir conveying device in the prior art, it is very long that it stirs feed spool, needs at head and the tail supporting to be set.Because the barrel discharging opening is provided with supporting, nature can hinder concrete conveying, increases the feeding resistance of feed spool blade.As if supporting dismounting with the barrel discharging opening, make the stirring feed spool be an end bearing form, then can influence the mechanical performance of clutch end, increase wearing and tearing, rotating the position owing to being correlated with all is that rigidity contacts supporting with connecting portion.

Summary of the invention

The purpose of this utility model is the helical stir pay-off that a kind of single-ended sinking support will be provided.

The technical solution of the utility model is: will stir the rotating mechanism of pay-off clutch end, and be designed to single-ended sinking support form, and in relevant contact site rubber sleeve will be set.

Stirring feed spool of the present utility model adopts single-ended flexible supporting structure, and the barrel discharging opening does not support obstruct, has reduced the feeding resistance.When gauge wear appearred in the blade that stirs feed spool, its single-ended flexible supporting structure can produce compensation automatically, made to stir that the feed spool assembly can not produce deflection deformation and the heel and toe wear that causes a last seal.

The specific embodiment

Introduce the utility model below in conjunction with accompanying drawing.

With reference to Fig. 1,2, by motor-operated reductor 1, its power output shaft is fixed on an end in the semiaxis 9, and the semiaxis other end is connected by the stirring feed spool 11 of flange with band blade 12.The semiaxis 9 outer chamber 10 of being equipped with, rubber sleeve 8 outside the seat chamber has retainer ring 7 outside the rubber sleeve 8.Be installed in the outer flanged plate 6 of semiaxis 9, fixing with the connecting flange 2 on the reductor 1 by minor axis 3, minor axis 3 places in the axle sleeve 5 on the connecting flange 2, is adorning rubber sleeve 4 between minor axis 3 and the axle sleeve 5.

With reference to Fig. 3,4, described seat chamber 10 1 ends are with bolted gusset piece 14, also are connected with bolt 15 on the flanged plate 6, in bolt 15 and the hole that gusset piece 14 cooperates rubber sleeve 13 are housed.

Claims

1, a kind of helical stir pay-off, have by motor-operated reductor (1), its power output shaft is fixed in the semiaxis (9), semiaxis is equipped with a chamber (10) outward, semiaxis one end is connected with stirring feed spool (11) by flange, is installed in the outer flanged plate (6) of semiaxis (9), and is fixing with the connecting flange (2) on the reductor (1) by minor axis (3), it is characterized in that: rubber sleeve (8) is equipped with in the outer seat chamber (10) of described semiaxis (9), and retainer ring (7) is arranged outside the rubber sleeve (8); Between the axle sleeve (5) on described minor axis (3) and the connecting flange (2) rubber sleeve (4) is housed; Described seat chamber (10) one ends are with bolted gusset piece (14), also are connected with bolt (15) on the flanged plate (6), in bolt (15) and the hole that gusset piece (14) cooperates rubber sleeve (13) are housed.
